Abstract

PURPOSE:To make it possible to simply and surely allocate a cargo vehicle to a predetermined position, by engaging an elevatable and retractable male member provided with a tire chock, with a female member which is secured to a platform. CONSTITUTION:When a cargo vehicle is moved backward and stopped at a predetermined position on a platform, parallel links 9, 10 are rotated by extending an elevating cylinder 13 to raise inner and outer cylinders 11, 12 in order to disengage a male member 16 from a female member 8. Then, the inner cylinder 12 is moved forward further from the outer cylinder 11 by extending a retractable cylinder 14. When a tire chock 6 abuts against a rear wheel RW, the extension of the retractable cylinder 14 is ceased, and as well the elevating cylinder 13 is retracted to rotate the parallel links 9, 10 downward. As a result, the male member 16 is engaged with the female member 8, the tire chock is fastened in the predetermined position, that is, the rear wheel WR is surely abutted against the tire chock 6.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a positioning device for stopping a vehicle at a predetermined position.

Generally, a stationary tilting device is used to discharge loads such as waste collected by a truck that is not equipped with a box tilting device to a predetermined position 1a, such as a bit.

When discharging a load using such a stationary tilting device, the rear wheels of the vehicle are held in a predetermined position by tire chocks to prevent the vehicle from falling into a pit.

In this case, since the rear overhang (distance from the rear wheels to the rear end of the cargo box) differs depending on the type of truck, it is necessary to move the tire chock described above to a specified position suitable for the type of truck.

However, in the conventional position determining device, the tire chocks had to be moved individually by manual operation, making the operation complicated.

The present invention has been made in view of the above points, and is provided with tire chocks on the engaged parts (A) and (B) fixed on the platform, and holds a retaining member that is movable and extendable in a predetermined position as appropriate. In this way, the truck is positioned at a specified position.

Embodiments of the present invention will be described below based on the drawings. Reference numeral 1 denotes a garbage processing factory, which has a garbage bit 2 and a platform facing the garbage bit 2 and having a sufficient area to place a truck 6. 4 are provided.

The vjS of this platform 4 is pivotally mounted on a base and is tilted rearward by an appropriate hoist mechanism 5, and the rear wheels RW of the truck 6 are mounted on the platform 4 in a specified position. A tire chock 6 for holding the tire is provided.

A positioning device for the tire chock 6 is shown in FIGS. 2 and 6.

A recess 7 is formed in a suitable position at the rear of the platform 4, and an engaged member 8, such as a saw blade, is implanted in the recess 7.

Further, an outer cylinder 11 supported by parallel links 9 and 10 is disposed within the above-mentioned recess 7, and an inner cylinder 12 is slidably inserted into the outer cylinder 11. .

In addition, one of the parallel links 9 and 10 is provided with an elevating cylinder 16 for rotating the parallel link, and a telescopic cylinder 14 for expanding and contracting the inner cylinder 12 is provided between the outer cylinder 11 and the inner surface 12. connected.

By the way, the connecting body 15 is located in the recessed part 7 on the inner cylinder 16 mentioned above.
The lower surface of this connecting body 15 has a retaining member 16 that can freely engage with the engaged member 8, and the above-mentioned tire chocks 6 are attached to both ends of the retaining member 16. Each is fixed.

Next, the operation of the present invention will be described. The freight vehicle 6 enters the platform 4 in a backward position and stops at a predetermined position. Next, when the lifting cylinder 16 is extended, the parallel links 9 and 10 rotate as shown by the chain line in FIG.
Since the outer cylinder 11 and the inner cylinder 12 rise slightly, the engaging member 16 reaches a state separated from the engaged member 8. When the telescopic cylinder 14 is extended in this state, the inner cylinder 12
moves forward from the outer cylinder 11. After stopping the extension operation of the envoy cylinder 14 at the position where the tire chock 6 comes into contact with the rear wheel, the elevating cylinder 16 is contracted and the parallel links 9 and 10 are rotated downward. Therefore, since the engaging member 16 fixed to the inner cylinder 12 is engaged with the engaged member 8, the tire chock 6 is secured at a predetermined position. At that time, Shin Jti? If the piston rod side oil chamber and the piston side oil chamber of the cylinder 14 are communicated with an oil reservoir (not shown), the engaging member 16 will be reliably moved to the appropriate engaged member 8 by forced descent due to contraction of the elevating cylinder 16. engage.

Since the tire chock 6 moves slightly rearward due to the downward rotation of the parallel links 9 and 10, the truck 6 is moved backward by that amount, and the rear wheel R'W is brought into contact with the tire chock 6 reliably.

Thereafter, when the platform 4 is tilted by the hoist mechanism 5 as shown by the chain line in FIG. The collected waste is discharged into the garbage pit 2.

In addition, by arranging the inner and outer cylinders within the recess formed in the platform, there is no interference with the differential or suspension system of the truck.

As described above, according to the present invention, the tire chock and the engaging member are provided in the elevating and retractable inner cylinder, so that the vehicle can be held in a predetermined position with a simple operation.
