Description

The invention relates to a vehicle for the transport of heavy hollow bodies according to the preamble of claim 1.

Such a vehicle is known from DE-GM 7 71 685. Here the lateral movement of the lifting arm is only from the inner telescope, which is in the outer telescope guided inner telescope with the help of two opposing ones Horizontal cylinder is movable laterally. Therefore at Creation of free passage between the lifting arm and the lifting mechanism retracted the piston rods of the lifting gear, after one between the outer telescope and the bearing block Plate has been swung in, which the swiveling down of the lifting arm prevented. Taking that into account to be transmitted in the outer telescope considerable load moments, so is the possibility of lateral movement of the inner telescope unfavorable, because the side Movement must be carried out just like the telescopic movement. This makes the lateral movement difficult and unsafe. In addition, the possibility of lateral movement through the Limited internal dimensions of the outer telescope. In addition the possibility of movement is restricted in that not the entire lifting arm, but only its outer part on the side is mobile. This affects difficult installation options the prefabricated garage, e.g. B. in narrow garage yards, disadvantageous.

DE 26 33 683 A1 describes a transport vehicle for prefabricated garages u. Like. Known one essentially rigid lifting arm that only at the top Telescope has, however, only for the adjustment of the garage suspension is mobile. Accordingly, it is Swivel bearing of the boom on the vehicle frame in the longitudinal direction the vehicle is movably mounted. Is agile  hence the support of the swivel mechanism on the vehicle frame in its longitudinal direction. The result is a complicated one Kinematics, which u. a. two parallel horizontal Swivel axes of the lifting arm and next to the vertical Swivel axis still a transverse guide of the lifting arm on one which requires pedestals. Characteristic of this known vehicle is also that there the storage of Lift arm also through the formation of the horizontal and the vertical Lift arm pivot axis is provided as a universal joint.

DE-OS 23 06 186 is finally a vehicle for the transport of reinforced concrete room cells, especially of Prefabricated garages, known, the bearing block is not on the Vehicle frame is attached, but on this in the longitudinal direction movable for loading and unloading. A hoist for supporting the Lifting arm in the area of the pedestal to create a free passage between the lifting arm and Vehicle frame for the bottom of the load and for carrying the Lift arms are not provided. Rather, at the rear end of the Lifting arms arranged by recesses in the bottom of the load extendable supports which the lifting arm is pivotable in height. The lifting arm is in the bearing block supported in such a way that a vertical lifting arm pivot axis is offset from a horizontal lifting arm pivot axis.

The displacement is included for loading and unloading a hollow body the hollow body suspension completely in the hollow body.

The object of the invention is to create a generic To improve the transport vehicle so that it has a Conveniently designed in terms of height and side pivoting Lift arm, which on the one hand a safe Garage parking guaranteed and on the other hand an optimal, even in difficult to access and narrow places allows accurate parking of the garage, the lifting arm during garage pick-up and drop-off by simple Is kept safe and stable.  

This object is achieved according to the generic transport vehicle by the characterizing features of claim 1 solved.

The bearing block preferably has one between two side shields around a horizontal one Axle height-adjustable frame box in the the circumferential distance the bearing end of the lifting arm engages, which by a vertical pivot axis is pivotally connected to the frame box.  

Seen in the direction of travel behind the bearing block are on the side of the vehicle frame two support cylinders or others Support elements arranged, which with their vertically movable Pressure part with laterally protruding abutments of the lifting arm interact to pivot its height.

The hoist located in the rear of the vehicle has one swiveling on the vehicle frame supporting carrying and sliding frame, which of the Lift arm is guided sideways and in which the lift arm by side pressure medium cylinders in one of the frame certain height range can be pivoted. Under a transverse slewing gear extends across the hoist with two pressure medium cylinders facing each other, whose piston rod for the side pivoting of the Lifting arm has an upwardly projecting driver, the detachable with the lower crossbar of the hoist frame is connectable.

The lifting arm is preferably formed by telescopes consisting of four positive interlocking square tubes (box profiles) exist and by two pressure medium cylinders arranged on the outside and an inner pressure medium cylinder in the vehicle longitudinal direction can be moved apart and moved together.  

The carrying arm arranged at the free end of the lifting arm and swivel device has one through a pressure medium cylinder height-adjustable lifting arm and one attached to it by a pressure medium cylinder Support arm, on which is a vertical Axis swiveling by means of pressure cylinder Supporting the recording table.

The vehicle according to the invention for the transport of heavy hollow bodies, in particular prefabricated garages 1 with or without floor 1 a, has a lifting arm 4 which is mounted on its transport frame 2 with a length end and can be pivoted in the longitudinal direction of the vehicle by means of pressure medium cylinders 3 a to 3 c, which extends from several, for example four, telescoping telescopes that can be pulled apart and formed in the form of tubes (hollow profiles, box girders or the like) 4 a to 4 d.

The lifting arm 4 is pivotally mounted with its length end on the bearing side, specifically with the free end of its largest external telescope 4 a in a gimbal-type bearing bracket 5 which is supported on the vehicle frame 2 , in the vertical and horizontal direction, so that the partially extended or completely Extended lifting arm 4 can be pivoted with its entire length in the vertical direction or in the lateral direction to both sides.

In a certain distance from this bearing block 5, the lifting arm 4 of a lifting mechanism 8 is supported on the vehicle frame 2 by means stuff pressure cylinder 6 in a limited area höhenschwenkbar and swing cylinder 7 a of a swivel work 7 from seitenverschwenkbar. The hollow body to be lifted, e.g. B. the prefabricated garage 1 is raised and pulled with its bottom 1 a up to the lifting mechanism 8 from the lifting arm 4 . Thus, the garage can be 1 further pulled to the vehicle, is provided between the bearing block 5 and the lifting mechanism 8 is disposed at least one lift arm 4 with lifting mechanism 8 höhenverschwenkender and bearing supporting cylinder 9 to the vehicle frame 2 is held by the lifting arm 4 at a certain height, and the lifting mechanism 8 can be raised, so that between the lifting arm 4 and the vehicle frame 2 a free space for carrying out the garage floor 1 a when loading and unloading the transport vehicle with a prefabricated garage 1 and for transporting the prefabricated garage 1 is created.

The free length end of the lifting arm 2 , that is, the free end of its smallest cross-section telescopic tube 4 d is equipped with a carrying and swiveling device 10 engaging in the garage 1 , by means of which the prefabricated garage 1 is captured under the roof 1 b and lifted onto the transport vehicle as well returned by the same and parked in the correct position.

The gimbal-shaped bearing block 5 , which is shown in more detail in the drawing figures 5 to 7, has two lateral bearing plates 11 fastened to the vehicle frame 2 , between which a box-like frame 12 is mounted so that it can be pivoted up and down by means of lateral, horizontal lifting arm pivot axes 13 . In this case frame 12 4 engages with all-round spacing the outer telescopic A, and is mounted seitenverschwenkbar in the horizontal direction by a top- and a bottom-side, vertical axis fourteenth The gimbal suspension of the lifting arm 4 has been achieved by the two axes 13 , 14 which are perpendicular to one another, so that it can be pivoted in the vertical direction and in the lateral direction.

The vertical lifting arm pivot axis 14 is arranged at a short distance behind or in front of the horizontal axis 13 , as seen in the direction of travel of the vehicle. It is preferred to arrange both axes 13 , 14 in a common plane. This bracket 5 extends near the vehicle cab 15 and in the region of the front wheel axle, preferably between two front wheel axles 16 .

In the vehicle direction of travel behind the bearing block 5 , i.e. at a short distance from the pivot axes 13 , 14 , two lateral pressure medium cylinders are mounted on the vehicle frame 2 as support cylinders 9 , which, with their piston part designed as a lifting part 9 a, extend laterally under the lifting arm tube 4 a Attack abutment 17 attached above to lift and carry the lifting arm 4 (see FIGS . 1, 5 and 7).

The lifting mechanism 8 extends at a significantly greater distance from the bearing block 5 than the support cylinders 9 and is preferably arranged above a rear wheel axle, preferably between two rear wheel axles 18 of the vehicle.

This from the drawings 1, 2 and in particular 4 clearly recognizable hoist 8 has an upright support and displacement frame 19 which is lifted by the lifting arm 4 , in particular the second telescope 4 b. The second telescope 4 b is guided by the frame 19 on both sides (mutual sliding system) and is provided to be movable in the height direction up and down in a certain area in the frame 19 . The frame 19 has a rectangular basic shape with its larger lateral extent extending in the vertical direction and is connected to the second telescope 4 b in the longitudinal direction of the lifting arm.

This frame 19 is supported during the lifting and lowering of a garage 1 on or from the vehicle on the vehicle frame 2 and is provided on this side pivot. Due to the lateral guidance of the second telescope 4 b, the lifting arm 4 is carried along with the lateral movement of the frame 19 . In order to achieve a power-saving lateral movement of the frame 19 with the lifting arm 4 and load, it is advantageous to equip the vehicle frame 2 in the area of the frame support with a slidable support surface 20 , which also during the length displacement (retraction or extension of the lifting arm tube 4 b) Advantage is.

The lateral displacement of the frame 19 and thus the lifting mechanism 8 takes place through the transverse swiveling mechanism 7 arranged in the vehicle frame 2 , which has two oppositely acting pressure medium cylinders 7 a, the common piston rod 7 b of which with a driver 21 projecting vertically upward from the vehicle frame 2 a bolt is equipped (see Fig. 4).

A lower crosspiece 19 a of the frame 19 has a bore 22 or an elongated hole in which (the) engages the driver 21 , so that there is a positive and movement connection between the frame 19 and swivel mechanism 7 , but which can be solved; the elongated hole 22 runs in the longitudinal direction of the vehicle.

The second telescope 4 b is provided with laterally protruding holding lugs 23 which enclose the frame 19 and thereby result in a sliding connection between the pivoting mechanism 8 and the lifting arm tube, between each of which a pressure medium cylinder 6 , preferably pivotally movable, is mounted in the vertical direction. These two lateral pressure medium cylinders 6 engage with their piston rod 6 a on a connecting piece 25 of the frame 19 so that when the piston rod 6 a is moved, a height movement (up or down) of the lifting arm 4 takes place within the height dimension of the frame 19 . The lifting arm 4 is pivoted in height independently of the support cylinders 9 about its horizontal bearing axis 13 .

Since the frame 19 must perform a certain pivoting in or against the direction of travel during this height pivoting, the frame 19 is provided on the underside with supporting pieces 26 which are articulated on the frame 19 and which are preferably formed by plates which rest on the slidable frame layer 20 and are laterally displaceable thereon, which are pivotally connected to the frame 19 by ball joints 27 and thus permit trouble-free and damage-free movement of the frame 19 relative to the vehicle frame 2 and also placement on the vehicle frame 2 (cf. exemplary embodiment left half of FIG. 4).

Another embodiment of the pivoting Aufsetzmöglichkeit of the hoist frame 19 to the vehicle frame 2 shows the right half of FIG. 4. Here, the two lateral bearing members 39 rigidly attached to the continuous lower frame web 19 a fixed and bear upwardly directed bearing plates 40, between each of which a on the frame 19 attached pivot member 41 which is movably connected by a hinge pin 42 to the tabs 40 to form a hinge pin connection between the frame 19 and support pieces 39 . The carrying and swiveling device 10 (compare FIGS. 1 to 3) has a lifting arm 29 which can be swiveled at one end in the horizontal swiveling axis 28 on the telescope 4 d, preferably by two levers running next to one another, which is articulated by two lateral, articulated on the telescope 4 d and the arm 29 engaging pressure medium cylinder 30 is pivoted about the horizontal axis 28 .

At the free end of the arm 29 , a support arm 32 is mounted in the horizontal pivot axis 31, which is pivoted by a pressure medium cylinder 24 , which acts in an articulated manner on the lifting arm 29 and on the support arm 32 . This support arm 32 carries a under the garage roof 1 b receiving table 33 , which is provided by a pressure medium cylinder 34 pivotably mounted on it and on the support arm 32 about a vertical axis 35 .

This receiving table 33 has laterally extendable, its table width-adjusting support pieces 33 a, with which the garage 1 for carrying in the corner areas between the garage roof 1 b and the side walls of the garage. The support pieces 33 a are held on pull-out guides 33 b.

The telescopically displaceable lifting arm 4 is preferably formed from form-fitting and thus directly mutually guided polygonal tubes, preferably square tubes, which represent the telescopes 4 a to 4 d. The telescopes 4 b and c 4 are two upper side on the lifting arm 4 to the outer telescopic 4 a bearing and with their piston rods to the telescopes, 4 b and 4 c acting pressure medium cylinder 3 apart in the longitudinal direction and pushed together. A third pressure medium cylinder 3 c arranged in the two telescopes 4 c, 4 d serves to extend and retract the telescope 4 d.

In the front (between the front wheel axles 16 ) area and in the rear (behind the rear wheel axles 18 ) area of the vehicle 2 height-adjustable support legs 36 are arranged on the vehicle frame, which are extended downwards onto the carriageway when the garage is taken up and when the garage is lowered, and the vehicle frame 2 underneath partially relieve the load on the wheels so that the vehicle is held stable and level by these support legs 36 .

Furthermore, on the vehicle frame 2 laterally extendable and insertable, angular guide pieces 37 are arranged, which hold the garage 1 in the lateral, lower corner area secured on the vehicle. These guide pieces 37 are adjusted according to the garage width with their pull-out guides 38 on the vehicle frame 2 .

The function of the vehicle according to the invention for receiving a prefabricated garage 1 from the floor is as follows:

The vehicle is moved backwards up to the garage 1 to be accommodated and then the front and rear support legs 36 on both sides are extended and locked on the floor by their pressure medium cylinders to secure the vehicle. Then the lateral extension of the guide pieces 37 and set up the same to the garage width, so that the garage 1 can be placed between them on the vehicle.

The telescopic lifting arm 4 is moved together, only the arm 4 b is extended by the pressure medium cylinder 3 a, and is supported by the lifting mechanism 8 on the vehicle frame 2 . The support cylinders 9 on the bearing side are retracted and thus ineffective, they do not give any support to the lifting arm 4 , but rather are supported horizontally in the vehicle longitudinal direction by the bearing block 5 and the lifting mechanism 8 .

Now the telescopes 4 c to 4 d are extended by the pressure medium cylinders 3 a, b, c, the carrying and swiveling device 10 being pivoted into the garage receiving position by their pressure medium cylinders 30 , 24 at the same time.

The lifting arm 4 moves with the support and pivot means 10 into the garage 1, wherein the receiving table 33 is located in an approximately horizontal position and engages under the roof of the garage 10th Should the vehicle are not in alignment with the garage 1, the lifting arm 4 can be set up 33 by the pressure medium cylinder 34 to the garage 1 by Seitenverschwenkung by means of the pressure cylinder 7 a of the swivel work 7 and / or by Seitenverschwenkung of the receiving table. Then the pressure medium cylinders 6 of the lifting mechanism 8 extend and thereby lift the lifting arm 4 , which swivels up about its horizontal pivot axis 13 in the bearing block 5 and grips with its receiving table 33 under the garage roof 10 and lifts the garage 1 off the floor.

Now the carrying and pivoting device 10 becomes effective and its pressure medium cylinders 30 , 24 extend, so that the lifting arm 29 pivots upward about its pivot axis 28 and the supporting arm 32 is pivoted against the lifting arm pivoting direction while maintaining its horizontal carrying position.

This carrying and swiveling device 10 raises the garage 1 until its garage floor 1 a comes to lie above the vehicle frame 2 . Now the telescope 4 d is retracted by the pressure cylinder 3 c and the garage 1 with its bottom 1 a under the lifting arm 4 and above the vehicle frame 2 is pulled onto the vehicle. If the garage 1 has been pulled with its front face up to the lifting mechanism 8 , the retracting movement of the telescope 4 d is interrupted. So that the garage 1 can be pulled completely onto the vehicle frame 2 , the lifting mechanism 8 must be raised to let the garage floor 1 a through. For this purpose, the support cylinder 9 now come into operation by extending its lifting part 9 a, which press under the abutment 17 of the lifting arm 4 and pivot the lifting arm 4 upward about its bracket-side horizontal lifting arm pivot axis 13 , so that the lifting mechanism 8 is thus relieved . The lifting mechanism 8 is raised by means of the pressure medium cylinder 6 , so that a passage for the garage floor 1 a is created between the lifting mechanism 8 and the vehicle frame 2 . Now the telescopes 4 b, 4 c, 4 d are retracted further, until the garage floor 1 a is pulled up to the end shields 11 . Then the support cylinder 9 and the arms 32 are retracted until the garage 1 settles on the guide pieces 37 .

Now the carrying and pivoting device 10 can be relieved by slightly retracting its cylinders 30 , 24 , since the garage 1 is supported by the vehicle frame 2 . Garage 1 can now be transported from the vehicle to its final location.

The deposition of the garage 1 is carried out in reverse order, by first moving the carrying and swiveling device 10 under the garage roof 1 b for grasping the garage 1 , then the extending support cylinders 9 lifting the garage 1 off the guide pieces 37 and then the telescopes Extend 4 b, 4 c, 4 d until garage 1 lies with its front end behind hoist 8 . Now the pressure cylinder 6 reduce the lifting mechanism 8 by lowering the frame 19 back to the vehicle frame 2, and previously to the bearing block 5 the lift arm 4 with garage 1-bearing supporting cylinder 9 to drive a, so that now the lifting arm 4 with garage 1 of the bearing block 5 and the hoist 8 is supported.

Then the telescope 4 d is extended further and as soon as the garage 1 has been pushed over the vehicle frame 2 , the carrying and swiveling device 10 places the garage 1 in its place.

Since a precise placement of the garage 1 is required, the garage 1 can be brought to its final position by pivoting the entire lifting arm 4 by means of the pressure medium cylinder 7 a of the swivel mechanism 7 and / or by pivoting the receiving table 33 by means of the pressure medium cylinder 34 .

The lateral pivoting of the entire lifting arm 4 takes place about its vertical pivot axis 14 on the bearing block side and through the pin connection 21 between the pressure medium cylinder 7 a and the lifting frame 19 , which is laterally displaced on the vehicle frame 2 .

All pressure medium cylinders 3, 6, 7, 9, 24, 30, 34, 36 are preferably formed by hydraulic cylinders.

The lateral pivoting of the center line of the lifting arm 4 and also of the pivot point 35 of the receiving table 33 is indicated in dash-dotted lines in FIG. 2.
