If the slide drive motor 27 is rotated after the storage lock lever device 14 is opened by the electric switch, the slide rack 31 is moved rearward by the slide pinion gear 29 transmitted by the rotation, and the slide platform 5 is moved rearward. It can be moved horizontally. For example, the backward movement of the slide platform 5 can be stopped by causing the front end plate 37 at the front end of the right U-shaped rail frame 24b to collide with the front roller 23a.

  Next, when the hydraulic cylinder 22 is a single-acting type, the hydraulic circuit connected to the hydraulic cylinder 22 is released, and the slide platform 5 is manually pulled out by holding the handle 38 to connect the upper arm 18a and the lower arm 18b to the upper arm lower shaft 18a1. And the lower arm shaft 18b1 about the lower arm moves rearward together with the slide platform 5, and the movement causes the slide lock lever device 33 on the transfer plate 25 between the left and right lower frames 20a1 and 20b1 to move rearward. Moves backward, the operating element contact portion 10a2 moves away from the support ring 11b of the operating element 11, and the slide lock lever 10 rotates about the support shaft 32 by the contraction action of the spring 9, and slides the contact lock portion 10a1. Engage with the tip of the lock block 8 of the platform 5 Sliding platform 5 is stopped from moving forward with respect to the plate portion 25. When the slide platform 5 is locked to the transfer plate portion 25 in this way and is further moved rearward by the handle 38, the piston rod 22b is pushed by the gravitational action to push out the oil in the hydraulic cylinder 22 to the hydraulic circuit and The slide platform 5 is lowered at a speed and is brought into contact with the landing surface 40 such as a road surface.

  If the hydraulic cylinder 22 is of the reverse operation type in which the push-up hydraulic circuit and the push-down hydraulic circuit are connected, if the push-up hydraulic circuit is opened and the push-down hydraulic circuit is closed and operated, the manual operation by the manual operation is automated. The pressing hydraulic circuit is also opened, and the slide platform 5 can be lowered at a constant speed to be brought into contact with the landing surface 40 such as a road surface.

  When the landing surface 40 on which the slide platform 5 is grounded is an inclined surface that is lowered forward as in the state shown in FIG. 1, even if a force is applied to the slide platform 5 in the direction of arrow C, that is, forward, the slide platform 5. Since the integral lock block 8 is engaged with the transfer plate portions 25 of the left and right side frames 20a and 20b via the slide lock lever 10, the forward movement is locked, and this forward force is applied to the slide platform. 5 is not transmitted only to the slide pinion gear 29 from the slide rack 31 on the upper side.

  Next, in order to raise the slide platform 5, when the hydraulic cylinder 22 is a single-acting type, the hydraulic circuit is closed and hydraulic pressure is applied to inject oil into the hydraulic cylinder 22 to push out the piston rod portion 22b. The arm 19a and the lower arm 19b are rotated about the upper arm lower stage shaft 18a and the lower arm lower stage shaft 18b, and moved upward together with the lifting mechanism 6, and the movement between the left and right lower frames 20a1 and 20b1. The slide lock lever device 33 on the transfer plate portion 25 is moved forward, and the operation member contact portion 10a2 of the slide lock lever 10 is pressed against the support wheel 11b of the operation device 11 fixed on the vehicle 2. As a result of the forward movement, the slide lock lever 10 extends the spring 9 around the support shaft 32 and slides. Is rotated from the lock block 8 de platform 5 on the inside, it is rotated to a position to avoid the path of travel of the locking block 8. Therefore, the lock between the slide platform 5 and the lifting mechanism 6 is released.

  In the case where the hydraulic cylinder 22 is a backward-acting type, the push-down hydraulic circuit is open, so the hydraulic cylinder 22 is lifted by closing the push-up hydraulic circuit, applying hydraulic pressure, injecting oil into the hydraulic cylinder 22 and pushing out the piston rod portion 22b. Similarly, the lock between the slide platform 5 and the lifting mechanism 6 is released.

  Here, the slide drive motor 27 is rotated in the opposite direction, the slide rack 31 is moved forward by the transmitting slide pinion gear 29, the slide platform 5 is horizontally moved rearward, and the slide platform 5 is disposed on the lower front end surface 5a. The collision portion 35a of the support plate 35 is caused to collide with the end stop plate 36 of the storage portion 3 and stopped, the slide platform 5 is stored in the storage portion 3, and the hook 13 of the slide platform 5 is engaged with the storage lock lever device 14. And lock to the stored state. The rear end plate 39 collides with the rear roller 23b at the rear end of the right U-shaped rail frame 24b and stops there. The front end plate 37 is removable.

Since the slide lock device of the slide platform in the vehicle lifting / lowering device of the present invention is as described above, the slide platform is reliably locked at the slide pull-out limit position outside the slide region. In addition, since it is linked to the lifting operation, it does not require new power, so it can be manufactured at low cost, and the slide lock will not be released even if an electrical trouble (such as a limit error) occurs. Therefore, the slide platform does not move.
Therefore, it is possible to provide a vehicle elevating device that is low in cost and ensures smooth operability and safety.
