Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a safety device for regulating the movement of a vehicle when the vehicle is tilted in a vehicle tilting device.

A conventional vehicle tilting device is provided with a positioning device that positions the vehicle and restricts backward movement.

However, such a positioning device must be formed low due to the relationship with the vehicle's rear bumper, leaf spring, etc. Therefore, when the vehicle tilting device is tilted, the positioning device has to be made low enough to restrict the backward movement of the vehicle. Because it was not high enough, there was a danger that the wheels would climb over the positioning device and fall.

In order to solve the above-mentioned drawbacks, the present invention moves the regulating member of the safety device, which is higher than the positioning device, so that it does not get in the way of bumpers or leaf springs when the vehicle is moving, and when the vehicle is tilted, the regulating member of the safety device is moved to the rear of the wheel when the vehicle is tilted. By moving it, it is possible to reliably restrict the backward movement of the vehicle.

The embodiment will be explained below with reference to the drawings. Reference numeral 1 denotes a frame having an area large enough to place a freight vehicle 2. The frame 1 is supported on a base 3 and its rear end is supported pivotably. , mount 1
It is tilted rearward by a hydraulic cylinder 4 provided between the base and the base 3.

A pair of underframes 6, 6 for positioning the rear wheels 5, 5 are provided on the rear left and right sides of the pedestal 1, facing inward from the sides of the pedestal 1. The height is sufficiently lower than that of the leaf springs 7, 7, etc.

The underframes 6, 6 are provided with safety devices 8, 8, which will be described later, and have a sufficiently higher height than the leaf springs 7, 7, etc. When rear wheel 5,
This is to restrict the rearward movement of 5.

Reference numeral 9 denotes a storage pit for garbage and the like provided at the rear of the pedestal 1. The pit 9 receives garbage and the like discharged when the freight car 2 is tilted. A conveyor 10 is provided to transport garbage and the like.

Since the pair of safety devices 8 and 8 have the same structure, only one side will be explained.
A threaded rod 13 supported via bearings 12, 12 is provided, and one end of the threaded rod 13 is directly connected to a hydraulic motor 15 fixed to a support frame 14, and when the hydraulic motor 15 is operated, the screw is rotated. The rod 13 is designed to rotate.

A movable member 16 is screwed into the threaded rod 13, and the movable member 16 has a vertical portion 18 projecting upward from a long hole 11 provided in the upper part of the underframe 6 in parallel with the screw rod 13. An L-shaped regulating member 20 consisting of a horizontal portion 19 extending horizontally from the upper end of the portion 18 in one direction of the mount is fixed, and movement of the regulating member 20 is regulated by the elongated hole 17. , the moving member 16 moves the screw rod 13 by rotation of the screw rod 13.
It is supposed to move on top.

Reference numeral 21 denotes a support member that extends rearward and diagonally downward from the horizontal portion 19 of the regulating member 20 and has a free end that abuts the locking piece 22 on the pedestal 1;
The support member 21 supports the regulation member 20 when the rear wheel 5 abuts the horizontal portion 19 of the regulation member 20.

Reference numeral 23 denotes a limit switch provided on the side of the vertical part 18 of the regulating member 20. The limit switch 23 is activated when the regulating member 20 moves inward from the side of the pedestal 1 by the operation of the hydraulic motor 15, and the horizontal part 19 The limit switch 23 comes into contact with the leaf spring 7 when facing the rear wheel 5, and the hydraulic motor 15
It is designed to stop.

Reference numeral 24 denotes a rubber plate that covers the elongated hole 17 at the top of the underframe 6, and the rubber plate 24 is fixed around the circumference with a stopper 25 and allows the vertical portion 18 of the regulating member 20 to protrude from the center along the elongated hole 1T. A slit 26 is provided for this purpose.

In the embodiment, one pair of safety devices is provided on the left and right sides, but the present invention can also be satisfied by providing one pair of safety devices on at least one side and using wires or the like to prevent the front wheels from shifting in the left-right direction.

Furthermore, the present invention can be satisfied even if a recess is provided on the frame instead of the frame as a positioning device.

The present invention has the above-mentioned structure. Next, the operation will be explained. First, the freight car 2 that has collected garbage, etc. is placed on the pedestal 1 while moving backward, and the rear wheels 5, 5 abut against the pedestals 6, 6. Freight vehicle 2 is stopped at the point where the freight vehicle 2 is located.

After that, the hydraulic motors 15, 15 are operated to control the regulating member 20.
．． 20 is moved from the two-dot chain line to the solid line in FIG.

When the regulating member 20.20 moves to the solid line in FIG. 3, the limit switch 23.23 comes into contact with the plate springs 7, 1, and the hydraulic motors 15, 15 are stopped.

At that time, the horizontal portions 19, 19 of the regulating members 20, 20 are arranged to face the rear wheels 5, 5, and when the hydraulic cylinder 4 is extended in this state, the pedestal 1 moves from the solid line in Fig. 1 to the dashed line. It is tilted, and garbage from the freight car 2 is discharged into the pit 9.

At that time, even if the rear wheels 5, 5 try to move backwards by climbing over the low wheels 6, 6, the restriction members 20, 20 are sufficiently high so that the movement of the rear wheels 5, 5 cannot be reliably restricted. It is now possible to do so.

Next, when the discharge is completed, the hydraulic cylinder 4 is contracted and the pedestal 1 is returned to its original position.

After that, the hydraulic motors 15, 15 are used to control the regulating member 20.20.
3 from the solid line to the two-dot chain line in Figure 3, and move the freight vehicle 2 forward without getting in the way of rear bumpers, etc.
As described above, in the present invention, the regulating member of the safety device can be moved inward from the side of the mount, and the regulating member restricts the backward movement of the rear wheels. It does not get in the way of springs, etc., and can move to the rear of the wheels when the vehicle is tilted, reliably fulfilling its role as a safety device.

In addition, even if the wheels are incorrectly positioned in the left-right direction, the vehicle can be operated satisfactorily as a safety device, making the vehicle extremely easy to operate.
