Abstract

(57) [Abstract] [Purpose] To facilitate the inspection and maintenance work of the lower part of the vehicle in the pit on the floor after the vehicle is lifted up, and to facilitate the running of the vehicle when the work is not done. To do. A lifting device 2 is provided in a recess 1a formed on the side wall of the pit 1 on the floor A and opening upward, and a tread plate 3 having a through hole 4 on the opening periphery of the recess 1a is detachably locked. Then, the support rod 5a of the vehicle body support attachment 5 is erected on the elevating upper end 2c of the elevating device 2 by penetrating the through hole 4 and the elevating device 2 is raised so that the vehicle body support attachment 5 becomes a tread. It rises regardless. Further, when the attachment 5 is removed, the vehicle can run on the tread 3. Further, when the tread plate 3 is unlocked from the peripheral edge of the opening and placed on the elevating upper end portion 2c, a worker can work on the tread plate 3.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention particularly relates to a lift device suitable for inspection and maintenance of the lower surface of a vehicle.

[0002]

[Prior Art]

 As a conventional lift device of this type, there is known a lift device having an attachment for supporting the vehicle body at the upper end installed in a pit formed on the floor.

[0003]

[Problems to be solved by the device]

 According to this conventional lifting device, there is a problem that the lifting device becomes large and the large lifting device becomes an obstacle, which makes it difficult for a worker to perform inspection and maintenance work in the pit.

It is an object of the present invention to solve these problems and provide a lift device that facilitates work in a pit.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention forms a concave portion that opens upward in the side wall of a pit formed on the work floor surface, installs a lifting device in the concave portion, and disengages the tread plate from the opening peripheral edge of the concave portion. It is freely locked, a through hole is formed in the tread plate, and a support rod of the vehicle body supporting attachment is detachably erected on the upper and lower ends of the lifting device through the through hole. To do.

[0006]

[Action]

 After passing through the through hole of the tread plate through the support rod of the vehicle body support attachment and erected at the lifting upper end of the lifting device, engage the vehicle axle, for example, with the attachment and lift the vehicle by the lifting device. A worker inspects and maintains the lower part of the vehicle in the pit.

If necessary, the tread plate is removed from the opening peripheral edge of the concave portion and placed on the elevating upper end portion, and a worker is placed on the tread plate to work. Further, the tread plate can be run on the tread plate by locking the tread plate to the peripheral edge of the opening and removing the attachment from the upper and lower ends.

[0008]

【Example】

 An embodiment of the present invention will be described with reference to FIGS.

Reference numeral 1 denotes a pit. The pit 1 is formed on the work floor surface A, and a side wall of the pit 1 is provided with a concave portion 1 a that opens upward.

Reference numeral 2 denotes an elevating device installed in the recess 1a. The elevating device 2 includes an X-shaped link 2a, a lower support frame 2b, an elevating upper end 2c and a hydraulic cylinder 2d. The upper end 2c moves up and down by the operation of the cylinder 2d. Reference numeral 2e indicates a control switch for actuating the hydraulic cylinder 2d, and the upper end portion 2c is provided with a through hole 2f for supporting a vehicle body supporting attachment described later.

Reference numeral 3 denotes a tread plate, and the tread plate 3 is normally locked to the peripheral edge of the opening of the recess 1 a by locking tools 6 ...

Here, each locking tool 6 comprises, for example, a locking piece 6a pivotally supported on a corner of the tread plate 3.

Reference numeral 4 is a through hole formed in the tread plate 3, and the through hole 4 is formed to be larger than the through hole 2f of the upper end portion 2c so that the support rod 5a of the vehicle body supporting attachment 5 can pass therethrough. A plurality of through holes 2f and 4 may be provided depending on the case.

Next, the operation of the above embodiment will be described.

With the locking piece 6 of each locking tool 6 protruding outwardly and the tread plate 3 locked to the opening peripheral edge of the recess 1 a, the vehicle to be maintained is advanced into the pit 1 and the axle B of the vehicle. Stop at the position of the through hole 4 of the tread plate 3.

Next, in the through hole 2f of the upper end portion 2c, the support rod 5a of the vehicle body supporting attachment 5 penetrates through the through hole 4 of the tread plate 3 and the lower end portion is fitted and locked, and the control switch 2e is operated. When the hydraulic cylinder 2d is moved upward, as shown in FIG. 2, the attachment 5 fitted into the through hole 2f rises together with the upper end 2c, the vehicle to be maintained is lifted up, and the operator in the pit 1 is lifted. The lower part of the vehicle can be serviced.

After the maintenance, the control switch 2e is operated to move the hydraulic cylinder 2d downward to disengage the vehicle body supporting attachment 5 from the elevating upper end portion 2c so that the vehicle can travel on the tread plate 3.

Further, when the locking piece 6a of each locking tool 6 is rotated to be positioned inward of the tread plate 3, the tread plate 3 is unlocked from the peripheral edge of the opening of the recess 1a, as shown in FIG. It is also possible to place the tread plate 3 on the upper end portion 2c so that the tread plate 3 moves up and down together with the upper end portion 2c, and an operator can rest on the tread plate 3 to work.

[0019]

[Effect of the device]

 As described above, according to the present invention, the elevating device is provided in the upwardly opening concave portion formed in the side wall of the pit on the floor surface, and the elevating device raises the elevating device so that the tread plate locked to the opening side edge of the concave portion is provided. Since the support rod penetrates through the through hole and the attachment for the vehicle body support that is erected on the upper and lower ends of the lifting device is raised, the vehicle is raised while the tread plate is locked to the opening side edge of the recess. In this way, the operator can inspect and maintain the lower part of the lifted vehicle in the pit, which facilitates the work, and by removing the attachment from the upper and lower end of the lifting device, The vehicle can travel easily, and if the tread plate is released from the side edge of the opening and placed on the elevating upper end portion, an operator can sit on the tread plate and work.
