Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mobile vehicle maintenance workbench that can continuously and efficiently carry out various maintenance work on vehicles, has an improved working environment, and has an improved work area.

Regular vehicle inspections and maintenance are required by law to check over 80 inspection items.

Conventionally, for such inspection and maintenance, a lift was used for each car, and several workers carried out inspection and maintenance on each car body by placing each car body on the lift and raising and lowering it.

Therefore, in order to quickly process this inspection and maintenance, it is necessary to install a large number of lifts that can inspect and maintain a large number of vehicles at the same time, to set up a place to move the vehicles to be placed on and off the lifts, and to carry out work on multiple ports at the same time. The conditions were poor, both in terms of work environment and work efficiency, including the number of skilled workers required to carry out the work.

Inspection and maintenance requires quick work, which not only requires a large work area and skilled workers who can quickly handle the work, but also requires several people to raise and lower each vehicle. The work environment is poor and efficiency is low due to multiple workers working at the same time.

Therefore, for vehicle maintenance, especially regular inspections required by law, which have many inspection items, we adopt an assembly line method for maintenance work, and by dividing and simplifying the work, it is necessary to speed up the work and require a large number of skilled workers. As a result of repeated tests and research aimed at creating a mobile maintenance workbench that allows maintenance work to be carried out reliably without any hassle, we have found that maintenance and inspection work can be carried out while moving the vehicle being serviced on an erected rail. Division of labor and simplification are possible, and the vehicle to be serviced is placed on this rail and moved on the rail by a drive device attached to the rail. When the vehicle is moved to a vehicle lifting platform installed at a predetermined position between the rails, the vehicle is released from the drive device and maintenance can be performed by raising the vehicle ascending platform. When getting on and off a vehicle on this rail, a movable platform that can be raised and lowered is attached at right angles to the direction of the rail at both ends of the installed rail, improving work efficiency and saving space in the workplace. Completed vehicle maintenance workbench.

The present invention improves the work environment by constructing rails equipped with drive devices, installing a vehicle lifting platform between these rails, and installing lifting platforms at right angles to both ends of the rails.
This is a mobile vehicle maintenance workbench that has good work efficiency and saves space in the workshop.

The mobile vehicle maintenance workbench of the present invention will be explained with reference to the accompanying drawing.

FIG. 1 is a plan view of a mobile vehicle maintenance workbench according to the present invention, and FIG. 2 is a front view of the same maintenance workbench.

The mobile vehicle maintenance workbench of the present invention has supports (1
According to 2), several, preferably two, rails fl) are erected in parallel. This rail (11) is equipped with a drive device (for example, a chain (2)) having an endless top plate that is connected to the drive section and driven on the top surface.The length of the rail is determined by the work items, and several pieces can be inspected and maintained at the same time. The construction should be long enough to provide sufficient work space.

In a case where several rails are used, the distance between the rails must be smaller than the distance between the front and rear wheels of the vehicle, since the body of the vehicle is placed across the rails.

Elevating platforms (3) that go up and down from the ground to the rail surface are connected to the rail +11 at both ends of this rail (110).This elevating platform (3) moves the vehicle to be serviced onto the rail, and also moves the vehicle that has been serviced onto the rail. It serves the function of lowering the vehicle to the ground, and is also used to place the vehicle to be serviced on the drive chain (2) on the rail (11).

Therefore, its structure consists of a part (3-1) that has an area large enough for a vehicle to ride on, a part (3-2) that is the same width as the part (3-1) and a cutout of the rail part, and (3-1). It consists of part (3-3) which has the same area as part 1).

A vehicle lift platform (4) is placed at a predetermined location between the above rail +11.
Set up. For example, as shown in Fig. 3, this vehicle lifting platform (4) has a lift cylinder (5) which is provided with a lift arm (7) having a portion (6) that contacts the bottom of the vehicle body. The base of the vehicle lifting platform (4) may be fixed to the ground or may be movable by means of a suitable moving device.

The drive device of the mobile vehicle maintenance workbench of the present invention is, for example, a third
As shown in the figure, a roller conveyor chain (2) having a fract (9) is fitted onto the rail (1), and this roller conveyor chain (2) is driven.

In the figure, 00) is a conveyor frame, (11) is a return roller, and (12) is a column.

There are several places (13), (14), (15) in the middle part (3-2) of the lifting platform (3) at both ends of the rail (11) of this mobile vehicle maintenance workbench, and in the middle part of the rail +11.
) ...A workbench is set up to inspect and maintain the inside of the vehicle.
It is used as a scaffold for work such as cleaning. This workbench (1

(14), (15) ...and the central part (3-2) of the elevator platform is usually made of a steel frame with a steel plate placed on it. It is convenient to have appropriate notches for simultaneous inspection and maintenance.

The use of the mobile vehicle maintenance workbench of the present invention will be described.

Place the vehicle to be inspected and maintained on the front part (3-1) of the lowered elevator platform (3) at the right end using the self-blade. This lifting platform (
3) Raise it to the height of rail (1). Afterwards, the vehicle is further advanced by its own blade and placed on the central part of the lifting platform (3-2) at the same height as the rail (1). At this time, the front and rear wheels of the vehicle are located at the front (3-1) and rear (3-3) of the platform. When descending from the platform (3), a part of the body of the vehicle is moved by the chain (
2) Contact the top fract (9) and chain (2)
The vehicle moves on the rails (11) in a direction perpendicular to the vehicle body.Then, when the vehicle moves to several vehicle lifting platforms (4) installed in the middle of the rails (1), the vehicle lifts (4).
A contact portion (6) provided on the lift arm (7) of the vehicle is brought into contact with the body of the vehicle. Then the lift cylinder (5
) to raise the cylinder shaft (8), the vehicle body is released from the chain (2) and is supported by the lift arm (7) of the vehicle lift platform (4) to ascend. Since the vehicle is stopped in this state, inspection and maintenance work (assembly, maintenance) on the bottom of the vehicle can be performed. After the predetermined work has been completed, the vehicle is moved to the elevator platform (3) at the left end, and the elevator platform (3) is raised by 2' to the front section (3-1).

When the rear part (3-3) matches the height of the rail, a part of the body is separated from the chain <2) by the front and rear wheels of the vehicle, and is moved to the front part of the lifting platform (3-1) using the rear self-blade and raised and lowered. Stand (3)
lower it and move it from this mobile vehicle maintenance workbench.

Since the mobile vehicle maintenance workbench of the present invention is constructed as described above, it has the following various advantages.

fll Since several vehicles can be mounted and moved at the same time on one workbench, vehicles to be serviced can enter and exit at one place per workbench, and the workspace area is small.

(2) Since the vehicle being serviced moves, the same work can be done at a specific location, creating a division of labor in which specific tasks are performed by specific workers. Therefore, difficulties in work management due to movement of one tool, one part, and one worker can be eliminated.

(3) Since the lifting, lowering, and movement of the car body can all be performed uniformly at a specific location, compared to the conventional lifting and lowering of each car using a lift, the work time is 9 hours, and the working environment such as location is significantly improved.
