März1969 ENGINEER SERIOUSNESS WIEGER AND ENGINEER ERHARD WIEGER IN DUESSELDORF (GERMANY) telescopic excavator announced at the 20.Feber 1967 (A 1666/67); Priority of the registration in Germany of the 26.Feber 1966 (W 41017 V/84d) stresses.
Beginning of the patent duration: 15.Mai 1968.
The invention refers to a telescopic excavator with an arm located on a bogie, which at least consists these of an arm part elevatortiltable connected with the bogie and opposite teleskoparüg an adjustable and Auslegertefl infinitely swivelling in a direction of rotation.
There is telescopic excavators well-known, with which the length of the hydraulic hoses, which limits to the devices in swivelling and lengthwise-adjustable arm part flthren, is so laid out that this arm part can drive out a rotating motion over only for 18o° after both sides. For the protection of the hoses attacks are intended for the delimitation of this rotating motion. In improvement of these telescopic excavators one suggested an arm at such excavators, which is infinitely swivelling in a direction of rotation at least.
The invention is not the basis the task to improve this well-known telescopic excavator in such a manner Trade Union of German Employees its range of application on the excavators remains limited, but e.g. also senkrechte drilling work and work with a swivelling Greffer with the excavator according to invention are feasible. The improvement is to be reached be able to be already attached with relatively simple means and gewünschtenfalls at existing telescopic excavators.
For the reaching of this goal the invention plans with a telescopic excavator eingangr of the kind mentioned that the arm at its front end one against a dredging bucket, drill od.dgl.
answechsdbaren cone drive for the turn of a work tool around a senkrechte axle carries.
After the excavator the Er£mdung can thus both to excavators and areas, for load lifting u.a.m, as well as as Bohreinrichtung for horizontal boring against mountain-slopes and also for senkrechten boring for holes e.g. from Telephonmasten application find. Furthermore easily senkrechte walls can be provided such as Spuntwände.
In accordance with a favourable training form of the excavator a grip arm for an unlimited period swivelling in both directions of rotation is solvable arranged at the senkrechten wave of the cone drive.
In the designs are represented Ausfülarungsbeispiele after Tdeskopbaggers the Er£mdung, u.zw show the Fig.1 and 2 the telescopic excavator with combined Lockerungsund excavator equipment.
Fig.3 the possibility of the arrangement of a well-known Baggereirners. Fig.4 the mounting Bohrund P, äumgerätes at the front end of for an unlimited period swivelling arm part, Fig.5 the front end of the same arm part with a bowl grip arm, Fig.6 a further execution form of the telescopic excavator with a Schwenkbarkeit around 180° of the arm part and Fig.7 the underframe of the excavator connected with the bogie.
On tracks --1-- or wheels (see Fig.7) displaceable vehicle frames --2-- is the bogie --3-- around a horizontal axle --4-- infinitely swivelling. On the bogie is the power supply unit --5-- and the not represented Steuerhaus attached.
Between two cheeks --6-- or a similar mechanism is the arm part --7-- around e ue horizontal axle --8-- tiltable and with two lateral beginnings --9-- provided, at their free end the piston rod --! 0-- a tiltable Hydraulikzyllnders or a pair of hydraulic cylinders attacks.
Opposite from/egerteil --7p is the further arm part --11-- toward the Doppelpfeihs --12-- verscMebbar. The arm parts --7 and Ii-- form the arm arm of the telescopic excavator, for that around the axle --8-- toward the double arrow --13-- is tiltable.
Erf'mdungsgemäß is the Teleskoptoil --11-- in relation to the telescope part --7-- at least in a direction of rotation, preferably however in both directions of rotation according to the double arrow --14-- for an unlimited period swivelling. For the reaching of these infinite swivellingness are between the Autriebsaggregat --5-- and the performing for the manipulation of the tools at the front end of the arm part --! 1-- intended hoses with actually well-known pnanmatischen or hydraulic Drehgetenken provide. A such device for the manipulation of a tool to betrayed end of the Auslegertdls --11-- is the Hydrau/ikz¥1inder --15--, its piston rod --16-- with one around an axle --17-- toward the double arrow --18-- tiltable tools --19-- is connected. This tools are in such a manner trained that it in Schwenkdchtung of the Doppe/arrow --18-- the mark as Baggereirner ---20--, other time than Lóckerungswerkzeug --21-- becomes effective, with the position of the tool --19--, with the dredging bucket --20-- one works, can be swivelled these from the represented position around 90° after both pages, i.e.
the dredging bucket is able to e.g. work on the side panels of a ditch. With the position of the equipment --19-- after Fig.2 is the loosening tool --21-- effectively, which is able to arbelfen 90° after both sides from the represented position. As the most favorable work-sore with the combined equipment a periodically interrupted rotation of the arm part in a direction results, whereby during interruption of the rotating motion in a direction the tool becomes swivelled 2s.
With the Ausführungs£orm after Fig.4 after the working on tool the Fig.1 and 2 bzw.3 by Bohrund is l äumwerkzeug --22-- replaced, that at its front end the drilling fixture --23-- and in its middle and rear part the Käumvorrlchtung in form of a snail --24-- exhibits. Instead of the equipment --19-- or Bohrund of clearing tool --22---can after the Ausführungsbeispiet after Hg.5 at the front end of for an unlimited period swivelling arm part --11-- one over the Kegelradantrleb --30-- around a Senkrechte S infinitely swivelling grab excavator shovel --31-- solvable to be arranged. In one at the arm part --11-- hanging and opposite this swivelling housings --32-- stored Kcgekadantrieb --30-- the rotating motion of the part transfers --11-- on the Greffer --31--, their Offnungsund Schließbewegung by the cylinder --15-- or through ehen at the C-ripely arranged cylinder one causes.
] 3el of the execution form after Fig.6 is the arm part --7-- fibre doubles abgewinkdtes lever linkage --25-- with the bogie --3-- connected. The lever linkage seizes here at the rear end --7a-- the arm part --7-- on, during at the front section of the arm part --7-- the bogie lengthen-adjustable Kdben also connected --26-- attacks. This lengthen-adjustable piston is preferably with its an end a kind of the axis of rotation of the bent Hebdgestänges --27-- stored. The manipulation of the lever linkage --25-- even takes place via a also drchbaren hydraulic cylinder --28--, which is attached at the bogie swivelling.
In Fig.6 the extreme positions of the two arm parts are in broken line --7,11-- of perpendicularly upward an arranged situation into perpendicularly downward an arranged position shown, whereby each further intermediate position --2 9.29 “, 29 “, 29” “, 29IV-- is possible. One sets at the uateren end by the arm parts --7 and 11-- on, then one can provide P£ostenbohrungen to bathed Auslegearraes Bohrund clearing equipment after Fig.4 and/or attach horizontal drillings even diagonally upward or arranged drillings in mountain-slopes. With perpendicularly or diagonally downward arranged position of the arm arm and arrangement of a tool --19-- after Fig.1, 2.3 and 5 one can e.g. manufacture senkrechte of sheet pile walls easily.
As is to be recognized from Fig.7, the excavator is over the bogie --3-- with the underframe --33-- the vehicle frame connected, that the impellers --34-- as well as the detour wheels --35-- for the tracks --1-- carries. These can be propelled, retarded in well-known way and braked against each other for control.
At the underframe --33-- is at the end --36-- a pair of dreieckförmiger arms --37 and 38-- tiltable stored. The free point of the arm carries the wheel bearing --39--, which carries a Halboder solid axle, whereby the engine --40-- for the drive of the Halboder solid axle provides, on that the tire wheels --41-- are attached. The Antriebsrnotor --40-- is at that or the arms --37-- in such a manner arranged that the arms --37-- with the engine to be elevatorswivelled, so the tire wheels know Trade Union of German Employees --41-- the position --41 '-- to take are able. The swivelling of the arms --37-- becomes by one or more Druckmittdzylinder --42-- caused, their piston rod --43-- at the third Dreieckseite of the arm --44-- attacks. That or the argument cylinders --16-- are --45-- swivelling at the underframe --33-- arranged.
The second end of the underframe --33-- carries for the arms --37-- similar, dreieckförmige arms --46--, at their front point of the triangle wheel bearings --47-- for the two wheels --48-- are intended. To the Auslegem --46-- seize the piston rods --49-- on, those of argument cylinders --50--, --5! -- tiltable at the underframe attack, to be operated. --52-- tiltable arm carry a steering linkage device --53--, by those the wheels --22-- are circle expensivable.
Preferably the argument cylinders possess --42,50-- a common argument producer, by that the piston rods --43,49-- at the same time and together in such a manner to be adjusted it can that even lifting and lowering of the tire wheels --4! , 48-- to take place can.
The size and arrangement of the arms --37,46-- it is in such a way selected that not only the tire wheels --41,48-- from their positions into the positions, represented in taken off line --41,48-- to be moved it can but that also the steering system --53-- and the driving motor --40-- without impairment of this adjustment movement 'at the Amlegern place finds, so that the front end of the crane or excavator on a road is independently of a drawing means verbahrbar. 1. Telescopic excavator marked by a Amleger, which consists at least of with the bogie a elevatortiltable connected and this in relation to telescope-like adjustable and arm part infinitely swivelling in a direction of rotation, arranged on a DrehgesteU, thereby that the arm (11) at its front end carries one against a dredging bucket, drill od.dgl, replaceable Kegekadtrieb (30) for the turn of a work tool around a senkrechte axle. 2. Telescopic excavator according to requirement 1, by characterized that to the senkrechten wave of the bevel gear drive is solvable arranged in both directions of rotation for an unlimited period swivelling grip arm (31).
