As shown in Fig. 3 to Fig. 6, the bogie body 5 of the vehicle suspension maintenance work vehicle 2 has four support legs 7, 7, ... with cassette wheels 6, 6, ... rolling on the floor G. , These support A rectangular lower shelf 8 fixed to the upper part of the legs 7, 7… and a similarly rectangular upper shelf 9 connected to the lower shelf 8 via four columns 10, 10… The mounting flange 1 la of the bearing bracket 11 is fixed to the center of the upper surface of the upper shelf 9 with a plurality of ports 29, 29. The bearing bracket 11 has a bearing cylinder 11b protruding upward from the mounting flange 11a.

The pivot 13 provided on the wheel receiver 12 is rotatably fitted on the inner peripheral surface of 1b. The wheel receiver 12 is where the wheel H removed from the lifted automobile V is placed. A pair of relatively long and parallel side bars 14, 14; and a pair of relatively short shafts 15, 15, 15 interconnecting both ends of these side bars 14, 14, and these shafts 15, 15, 1 5 and rollers 16 and 16 rotatably fitted to the wheel 5. The shafts 15 and 15 support the wheel H in an upright state via the rollers 16 and 16, and the rollers 16 and 16 This allows smooth rotation of the wheel H.

A pair of grips 17, 17 extending upward are integrally connected to both ends of one side rod 14, and an operator Ma (see Fig. 2) holds these grips 17, 17 to maintain the leg area. The work cart 2 can be moved.

As clearly shown in Figs. 4 and 5, a plurality of (three in the example shown) cylindrical tool holders 18, 18, ... are attached to the periphery of the upper shelf plate 9, and these are used as pneumatic impact wrenches. 19, nut runner 20, and tire air replenisher 21 with air pressure gauge 21a are held. On the upper surface of the upper shelf 9, a fixture tray 38 for holding various wrenches is fixed.

Further, as shown in FIG. 9, a plurality of nut support pins 23, 23,... For supporting a plurality of wheel nuts 22, 22,.

The bogie body 5 is also provided with the pneumatic impact wrench 19 and the nut runner 20, and a high-pressure air conduit 24 for supplying high-pressure air to the tire air replenisher 21. The high-pressure air conduit 24 is L-shaped from one side surface to the bottom surface of the bogie main body 5. The upper end of this high-pressure air conduit 24 projects above the upper shelf 9. It is equipped with an upper joint 25 for connecting the high-pressure air supply main pipe of the factory, and the operator Ma connects the high-pressure air supply main pipe to the upper joint 25 without bending down. You can connect. In the middle of the high-pressure air conduit 24, a pressure regulator 26 is connected. A plurality of lower joints 28a to 28c are provided on the lowermost surface of the high-pressure air conduit 24, and a flexible conduit 27a connected to the impact wrench 19, the nut runner 20, and the tire air replenisher 21 is provided. ~ 27c are connected.

As shown in Fig. 7 and Fig. 8, on the inner peripheral surface of the bearing cylinder 11b of the bearing bracket 11, the outer peripheral surface of the pivot 13 of the wheel receiving portion 12 is rotatably fitted. Bush 30 is fitted. A flange 31 is formed at the upper end of the bearing cylinder 11b, and a flange 32 supported on a plurality of flat washers 34, 34 is formed on the pivot 13 on the upper surface. A pin hole 35 is formed in the flange 31 so that a stop pin 36 with an image 36a can be freely inserted and removed. On the other hand, the flange 32 is provided with a sector-shaped notch 37 for receiving the stopper pin 36, and the stopper pin 36 comes into contact with both side walls 37a and 37b of the notch 37. The rotation of the wheel receiving portion 12 with respect to the bogie body 5 is restricted to a predetermined angle, for example, 45 ° in the illustrated example. Therefore, the stopper pin 36 and the notch 37 constitute a rotation restricting means 39 for stopping the rotation of the wheel receiving portion 12 around the pivot 13 at a predetermined position. If the stop pin 36 is pulled out from the pin hole 35, the rotation of the wheel receiving portion 12 becomes free.

One or two of the four casings 6 are provided with a brake 6a for preventing rotation of the wheels.

In the maintenance work around the foot of the vehicle V, first, as shown in Fig. 1, the vehicle V is lifted up by the lift 1 to a predetermined height slightly higher than that of the work vehicle 2, and then the worker is lifted. Ma moves the maintenance work carriage 2 by gripping the grips 17 and 17, and arranges its wheel receiving portion 12 immediately below the wheel H of the vehicle V, and applies the brake 6a of the cascade 6 with a brake. Let At this time, one side wall 37a of the notch 37 of the flange 32 of the pivot 13 is brought into contact with the stop pin 36 inserted into the pin hole 35 of the flange 31. Flatten the long side of 9 and the long side of the wheel receiver 1 2 Let go.

Therefore, the wheel nuts 22, 22 ... of the wheel H of the car V are removed by the impact wrench 19 taken out from the tool holder 18, the wheel H is removed, and the wheel H of the wheel receiving portion 12 is removed. 6, Place it in an upright position on 16. At this time, the wheel nuts 2 2, 2 2... Removed from the wheels H are held over nut support pins 2 3, 2 3.

After that, when servicing the brakes and suspension system, grip the grips 17 and 17 and rotate the wheel receiving part 12 around the pivot 13, but the notch 3 7 in the flange 3 2 When the other side wall 37b of the wheel abuts against the stopper pin 36, the rotation of the wheel receiving portion 12 is restricted to 45 ° in the illustrated example. In this way, the tool tray 38 on the upper shelf 9 can be revealed by the relatively small angle rotation of the wheel receiving portion 12, so that the desired tool required for maintenance can be easily obtained from the tool tray 38. Can be taken out.

After the maintenance is completed, the wheel H on the wheel receiving section 12 can be mounted on the vehicle V in the reverse manner.

By the way, since the undercarriage maintenance work vehicle 2 has the wheel receiving portion 12 disposed at the uppermost portion, the wheel support portion 12 can be attached to the vehicle V without causing the maintenance work vehicle 2 to interfere with each part of the vehicle V. Can be placed immediately below the wheel H of the vehicle. Therefore, the work of transferring the wheel H between the vehicle V and the wheel receiving portion 12 can be easily performed, and the labor of the worker Ma can be reduced.

In addition, since the tool tray 38 is disposed on the upper shelf 9 of the bogie body 5, the wheel receiving portion 12 is set at a predetermined angle in order to use a tool such as a wrench on the tool tray 38. The tool tray 38 does not move even when the wheel H is moved away from the tool tray 38 by rotating, and the direction of the tool on the tool tray 38 is not changed. The efficiency of maintenance work can be improved without losing even a moment.

In addition, since the rotation angle of the wheel receiving portion 12 is regulated by the cooperation of the stopper pin 36 of the flange 31 and the notch 37 of the flange 32, excessive rotation is prevented and work efficiency is reduced. Further improvement can be achieved. In the wheel receiving portion 12, the outer periphery of the standing wheel H is supported by a plurality of spindles 15, 15 having rollers 16, 16, so that the rotation of the rollers 16, 16 causes the wheel H to rotate lightly. This makes it possible to easily perform checks such as damage checks over the entire circumference of the tire and to adjust the phase when the wheel H is mounted on the vehicle V, thereby further improving work efficiency. .

Next, a description will be given of the maintenance work vehicle 4 around the vehicle engine with reference to FIGS. 1, 2, and 10 to 12. FIG.

The automobile engine maintenance work vehicle 4 includes a plurality of (three in the illustrated example) columns having wheels 40, 40 ... arranged on the pair of rails 3, 3, and two sets of columns 41, 41 ... An aerial work step 42 horizontally connected to the upper end of 41, 41 ..., and a pair of stairs 43, 43 connected to the left and right ends along the longitudinal direction of the rails 3, 3 of this aerial work step 42 A pair of handrails 44, 44 are provided upright at the left and right ends of the high work step 42. An extension step 45 is pivotally supported at the front end on the lift 1 side of the aerial work step 42 so that it can be deployed forward, and a shelf plate is mounted on the upper end of a support frame 46 standing from the rear end of the aerial work step 42. 47 is attached so that it protrudes rearward. On the shelf 47, a large tray 48 is fixed at the center, and a pair of small trays 49, 49 'are fixed on both sides. The large tray 48 has, for example, a pail 50 storing engine oil, The small tray 49 contains containers and lamps and other parts for storing, for example, battery fluid, window fluid, and the like, and the small tray 49 'contains various tools such as a wrench and a screwdriver.

Thus, as described above, the engine surrounding maintenance work truck 4 is used to lift the vehicle by the lift 1 and maintain the surroundings of the vehicle, and at the same time, maintain the vehicle V around the engine. You.

That is, after the vehicle V is lifted up, the maintenance work truck 4 around the engine is moved from the retreat position with the extension step 45 expanded to the work position in front of the engine room of the vehicle V lifted up, and the rail 3 , 3 Stop some wheels 40 on. By using the rail 3 to move the maintenance work truck 4 around the engine in this way, it is easy to set the maintenance work truck 4 around the engine to the working position. This also contributes to improving work efficiency.

Then, with the engine surrounding maintenance trolley 4 set in the working position, the extension step 45 enters directly below the front bumper of the vehicle V, and there is no gap between the high-level work step 42 and the front end of the vehicle V. As a result, it is possible to prevent tools and parts from falling, and also to improve the safety of work in step 42 at high places.

Next, the worker Mb (see Fig. 2), who is in charge of maintenance around the engine, goes up to the high-altitude work step 42 using the stairs 43, 43, and opens the hood B of the car V. Alternatively, open the bonnet before lifting up the car V. Then, in step 42 at high places, not only maintenance around the engine of the car V but also maintenance of lamps such as headlamps can be easily performed. In particular, when replacing the engine chill, the removal of the oil drain port at the lower part of the engine and the treatment of the discharged oil are performed by the worker Ma who performs the maintenance of the suspension of the vehicle V using the above-mentioned suspension work trolley 2. With the cooperation, oil change can be performed quickly.

In addition, since a pair of handrails 44, 44 are provided at the left and right ends of the high-level work step 42, the work in the high-level work step 42 can be safely performed by grasping or leaning against it. It can be carried out.

In addition, the large trays 48 containing the pail cans 50 and tools and the small trays 49, 49 'are fixed to the shelves 47 provided behind the high-altitude work steps 42. The operator Mb can take out the desired items from the trays 48, 49, 49 'simply by turning around, without being disturbed by the trays 48, 49, 49'. In addition, maintenance around the engine can be performed, which can contribute to improving work efficiency.

As described above, once the vehicle V is lifted up, as shown in Fig. 2, the underbody maintenance worker Ma using the undercarriage maintenance work vehicle 2 and the underbody engine maintenance work vehicle 4 are used. The engine surrounding maintenance workers Mb simultaneously perform their respective maintenance tasks and cooperate with each other, so that the entire vehicle V can be quickly maintained and the maintenance work time can be significantly reduced. It becomes possible.

In particular, four maintenance workers M a corresponding to the four wheels H, H… of the automobile V However, if they work simultaneously using the undercarriage maintenance work cart 2, the maintenance work time can be further reduced.

In addition, since the use of the lift 1, the suspension work truck 2 and the engine work truck 4 eliminates the need to form a working pit on the floor G, maintenance equipment can be obtained at relatively low cost. It can greatly contribute to cost reduction.

The present invention is not limited to the above embodiment, and various design changes can be made without departing from the scope of the gist.
