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 and has an improved working environment and 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 have a large number of lifts that can inspect and maintain a large number of vehicles at the same time, a place to move the vehicles to be placed on and off the lifts, and a place where various types of work can be done at the same time. The conditions were extremely poor, both in terms of the 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 testing and research with the aim of creating a mobile maintenance workbench that allows maintenance work to be carried out reliably without any hassle,
By performing maintenance inspection while moving the vehicle to be serviced on the erected rails, it is possible to separate and simplify the maintenance and inspection work.
When moving on the rail, we use a dolly mounted on the rail that can be arbitrarily engaged and released by a clutch attached to the drive device attached to the rail, and when getting on and off the bogie, it is possible to move up and down freely on both ends of the installed rail. We have completed a mobile vehicle maintenance platform that improves work efficiency and saves space in the workshop by installing a lifting platform perpendicular to the rail direction.

In the present invention, a rail equipped with a drive device is installed, a truck with a clutch is placed on this rail, and a lifting platform is attached at right angles to both ends of this rail. This improves the working environment and improves work efficiency. It is also a mobile vehicle maintenance stand that saves space in the workshop.

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

FIG. 1 is a plan view of a mobile vehicle maintenance stand of the present invention, and FIG. 2 is a front view of the same maintenance stand (however, excluding the trolley).

The mobile vehicle maintenance stand of the present invention is provided with supports (supported at a predetermined height, approximately sufficient for an operator to stand and inspect and service the bottom of the vehicle body).

erect. This rail (1) has a drive device on its top surface,
For example, an endless chain (2) connected to and driven by a drive unit is attached. The length of the rail will be long enough to provide a work space where several inspections and maintenance can be carried out simultaneously depending on the work item.

Note that when several rails are used, the spacing on both sides must be smaller than the spacing between the front and rear wheels of the automobile, since the vehicle body is placed on a bogie on the rails.

Elevating platforms (3) that ascend and descend from the ground to the rail surface are attached to both ends of the rail (1). This elevating platform (3) functions to move the vehicle to be serviced onto the rail, lower the vehicle that has been serviced from the rail to the ground, and also places the vehicle to be serviced on the trolley (4) on the rail (1). It is also used for the purpose of placing Therefore, the structure has the same width as the part (3-1) which has an area large enough for a vehicle to ride on, and the part (3-2) which is a cutout of the rail part, which has the same area as the part (3-1). 3) It is made up of parts.

Several sets of carts (4) on which vehicles to be serviced are placed and moved are placed on the rail EllO.

An example of the structure of this truck is shown in Figs. 3 and 4.

FIG. 3 is a front sectional view of the truck, and FIG. 4 is a side sectional view.

This trolley is formed into a cylindrical shape having a cushion (6) on the upper surface of the trolley frame (5) that contacts the body of the vehicle to be serviced, and a drive device such as a chain (2) attached to the rail +11 is engaged with the central part of the cushion (6). The clutch (7) is connected to a clutch bar (8), and the eccentric cam 00
), a clutch mechanism is provided which can arbitrarily disengage the clutch (7) from the chain (2) from the outside. Furthermore, wheels (11) suitable for sliding on the rails (1) are provided on both sides of the clutch part.

It is the pillar of

In the mobile vehicle maintenance stand of the present invention, when two rails are used, the above-mentioned trolley usually has four rails to support one vehicle.
By using one set of vehicles and using several sets of this one set of trolleys, several vehicles can be placed on this maintenance stand and inspection and maintenance can be carried out at several locations at the same time.

The central part (3-2) of the elevating platform (3) at both ends of the rail +11 of this mobile vehicle maintenance stand, and several places (14), (15), (16) in the middle of the rail (11)
...A workbench will be provided and used as a scaffold for work such as inspecting, servicing, and cleaning the inside of the vehicle. This workbench (14)
, (15), (16) ...and the central part (3-2) of the elevator platform is 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 stand of the present invention will be explained.

Place the vehicle to be inspected on the (3-1) part of the lowered elevator platform (3) at the right end using the self-sawing blade. This lifting platform (3)

)put on top. At that time, the front and rear wheels of the car are on a platform (3-1)
, in part (1-3). Then, the cushions (6) of the trolley (4) are applied to four locations on a portion of the body of the automobile, and the elevator platform (3) is lowered. As a result, the vehicle body is supported by the bogie (4) and placed on the rail (gJ:).

At this stage, the worker inspects and cleans the bottom of the vehicle body on the lowered platform (3-2).

During this time, the clutch (7) of the trolley (4) is connected to the thalassotile lever (
9), it is placed in an open state with the driven chain (2).

When the above first inspection and maintenance work is completed, the worker operates the thalassotile lever (9) and the clutch (7) of the trolley (4).
is in mesh with the drive chain (2). Dolly (4
) is moved in the driving direction, that is, to the left, perpendicular to the vehicle body due to the engagement of the clutch (7) with the chain (2). Then, move to the next workbench (14) and release the clutch lever.
(9), the clutch (7) of the truck (4) is opened to the drive chain (2) to stop the truck, and the second
Perform inspection and maintenance work (disassembly, repair). Then, the operator repeats the same operation of the tara no chi lever, stops at a place where there is no workbench, and works on the bottom of the car body. Operate the latch lever in the same way, move and stop at the work platform (15), perform the third inspection and maintenance work (assembly, maintenance), and then operate the thalasso lever in the same way to move to the work platform (16). It moves to a certain position and stops to perform the fourth inspection and maintenance work (inspection). In this way, the vehicle body is stopped at an arbitrary position by operating the trolley (4), and inspection and maintenance work is performed according to each procedure. 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 (3-1).
When part (3-2) matches the height of the rail, a part of the body is separated from the trolley (4) by the front and rear wheels of the vehicle, and is moved onto the lifting platform (3-1) using the rear self-blade. 3) is lowered and moved 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.

(1) Since several vehicles can be mounted and moved simultaneously on one workbench, vehicles to be serviced can enter and exit from only one place for each 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 tools, parts, and workers can be eliminated.

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

(4) The vehicle body can be moved extremely easily by operating the clutch on the trolley, and the vehicle body can be stopped at any desired location on the workbench, making the work extremely convenient.
