Description

[Detailed explanation of the invention] (Industrial application field) This invention is installed in an automobile inspection and maintenance factory, and allows the vehicle body to be maintained to be transported to each work location, and inspection and maintenance work can be performed without having to transfer it directly. This invention relates to an improvement of a vehicle body transfer device for automobile body inspection and maintenance.

(Prior art) Conventional vehicle body transfer devices for inspection and maintenance of automobile bodies include one in which a lift is freely suspended from a guide rail installed on the ceiling, and the other in which a lift is freely suspended on a traveling rail laid on the floor. It is known that it was set up in

(Problem that the invention aims to solve) However, in the former case, the large traveling mechanism and lifting mechanism are concentrated on the top of the lift, so the traveling mechanism and lifting mechanism may get in the way in places with low ceilings. There are problems in that it cannot be installed and is not stable, causing shaking and twisting, making it difficult to perform safe inspection and maintenance.Also, in the latter case, the running rails laid on the floor get in the way of work and are difficult to run. Dust, oil, etc. tend to accumulate in the grooves along the rail, resulting in a poor working environment, and there is also the problem that the lift is likely to derail due to tools remaining on the guide rail.

(Means for Solving the Problems) The present invention was completed with the aim of creating a vehicle body transfer device for inspection and maintenance of automobile bodies that does not have the above-mentioned problems. In a device that is suspended and supported on a guide rail such that it can run and move up and down, the lift has a suspension frame that is suspended from the guide rail so that it can run freely, and a lifting frame that is attached to the front of the frame via wheels so that it can move up and down. a frame, an elevating cylinder with a piston rod tip attached to the middle of the axles of a pair of wheels guided by guide grooves on the inside of both side pillars of the hanging frame, and a lower end attached to the hanging frame, the lifting frame and the hanging frame. It is a cantilever type consisting of a chain wheel attached to an axle so as to wrap around a chain with a fixed end, and the hanging frame is attached to a guide rail provided laterally between the floor and ceiling. It is characterized by a guide roller provided on the rear surface of the lower part of the holder in contact with the guide roller.

(Function) With this structure, the lifting frame of the lift, which is freely suspended from the ceiling guide rail, is lowered along the front surface of the hanging frame by the operation of the lifting cylinder of the lifting mechanism. Then, the lifting frame of the vehicle to be serviced is supported by a body holding arm at the lower end of the lifting frame, and then the lifting cylinder of the lifting mechanism is operated in reverse to raise the lifting frame supported in a cantilevered manner on the hanging frame. , the vehicle may be transported to the work site while suspended by a lift frame, and inspection and maintenance may be performed while suspended in the air.

(Embodiment) Next, the present invention will be described in detail with reference to the illustrated embodiment. Reference numeral 1 is a lift that is movably suspended from a guide rail 2 on the ceiling. It consists of a suspension frame 4 which is suspended so as to be freely movable via wheels 3, and an elevator frame 6 which is attached to the front surface of the suspension frame 4 via wheels 5 so as to be movable up and down,
Vehicle body holding arms 7, 7 are attached to the lower end of the elevating frame 6 so as to be pivotable in the horizontal direction. 8
is a lifting mechanism that moves the lifting frame 6 up and down. A lift cylinder 12 with the tip of the piston rod 11 attached and a lower end attached to the suspension frame 4, and a chain 13 with one end fixed to the lift frame 6 and the other end fixed to the suspension frame 4 are wrapped around the axle 10. Installed chain wheel 14
It depends on this. Reference numeral 15 denotes a guide rail provided laterally between the floor and the ceiling, and a guide roller 16 pivotally supported on the rear surface of the lower end of the hanging frame 4 is brought into contact with the guide rail 15 to facilitate the movement of the lift 1. It is for the purpose of Further, the pillars on both sides of the suspension frame 4 also serve as rails for guiding the pair of front and rear wheels 5 of the lifting frame 6, and the guide rails 17 are vertically installed from the ceiling toward the floor surface in order to support the guide rails 15. It is a pillar. In addition, in the illustrated embodiment, the elevator frame 6 has three
A vehicle body holding arm 7 is provided on each of the main pillars, but the central pillar that extends forward is eliminated, and the vehicle body holding arms 7 provided on the two left and right pillars are lengthened to create a forklift type. It can also be used as a.

With this structure, the lifting cylinder 12 of the lifting mechanism 8 is operated in reverse to move the lifting frame 6 of the lift 1, which is movably suspended from the guide rail 2 on the ceiling, through the piston rod 11 and the axle 10. By lowering the suspension frame 4, the vehicle is lowered along the front surface of the suspension frame 4 via the chain 13, and then the vehicle to be serviced is advanced to a position where it is supported by the vehicle body holding arms 7, 7 at the lower end of the elevator frame 6. When the lifting cylinder 12 of the lifting mechanism 8 is operated, the axle 10 rises via the piston rod 11, and the lifting frame 6, which is supported by the hanging frame 4 in a cantilever manner, moves along the hanging frame 4. 13, the vehicle is suspended in the air by the lifting frame 6. At this time, the lifting frame 6, which is supported in a cantilever manner by the hanging frame 4, is lifted by the weight of the vehicle. Therefore, even if the lift 1 tries to tilt backward, the lift 1 will tilt backward because the rear surface of the suspension frame 4 supports the guide rollers 16 in contact with the guide rail 15 provided laterally between the floor and the ceiling. In addition, since the pair of wheels 9 are guided by the guide grooves on the inside of both side pillars of the suspension frame 4, the vehicle can be driven smoothly without lateral sway, and the vehicle to be serviced can be placed in the designated place. Not only can it be easily transported, but it is extremely stable, so inspection and maintenance can be performed while it is supported by the vehicle body holding arms 7, 7 at the lower end of the lifting frame 6, eliminating the need for relocation. be able to. Furthermore, the elevating frame 6 is supported by an elevating cylinder 12 and a chain 13 on the front surface of the hanging frame 4, which is movably suspended with its upper end from the guide rail 2 on the ceiling, so that it can be moved up and down. Since mechanisms and traveling mechanisms are not concentrated in the upper part of the lift, the lifting frame 6 can be raised until its upper end is close to the guide rail 2 provided on the ceiling, making it possible to install it in a building with a low ceiling. Furthermore, an elevating cylinder 12 is provided, in which the tip of a piston rod 11 is attached to the middle of the axle 10 of a pair of wheels 9 guided by guide grooves inside both side pillars of the hanging frame 4, and the lower end is attached to the hanging frame 4, and The axle 1 is wound around the frame 6 and the suspension frame 4 with a chain 13 whose ends are fixed.
The elevating mechanism consisting of the chain wheel 14 attached to
In addition, since it is a hanging frame type and does not require running rails on the floor, it has improved workability and work efficiency compared to transfer equipment with running rails on the floor. There are various advantages such as no deterioration of the environment and no derailment or damage to the lift.

(Effects of the invention) As is clear from the above description, the invention is of a cantilever type, so the work space can be used effectively, and the lifting frame can tilt backward or sway sideways due to the weight of the vehicle. The vehicle can run smoothly without shaking, and the vehicle being serviced can be easily transported to the designated location.It is also extremely stable, so it can be kept supported by the vehicle body holding arm at the bottom of the lift frame. In addition, since the lifting mechanism consisting of a lifting cylinder and chain does not need to be installed centrally at the top of the lift, the upper end of the lifting frame can be raised to the vicinity of the guide rail installed on the ceiling. This makes it possible to install it in buildings with low ceilings, and since the amount of lifting and lowering is amplified to twice the amount of operation of the piston rod, excellent performance can be achieved with a small lifting cylinder, making it possible to use a conventional car body. It has a simple structure that eliminates the problems of vehicle body transfer devices for inspection and maintenance, is easy to construct, and can be provided at low cost, so it has great practical value.
