Abstract

PURPOSE:To facilitate the operation for unloading loads even from an ordinary truck, by providing a tilting table near an unloading site, which is rotatably pivoted at one end to be tilted by a dump cylinder and has a car stop projection on the upper surface at the end. CONSTITUTION:A lock lever 7 is rotated clockwise around a pivot 8 by extending the piston rod of a lock cylinder 9, and fallen down below the upper surface of a tilting table 3. In this state, a truck 1 is reversely moved onto the tilting table 3 and stopped when the rear wheels touch a car stop 4. Then, the lock lever 7 is risen up to lock the rear wheels to the car stop 4 for placing the truck on the tilting table 3. Thereafter, the tilting table 3 is rotated counter- clockwise around a pivot 5 by extending the piston rod of the dump cylinder 6, and the tilting table 3 and the truck 1 are risen up and tilted backward. Consequently, the loads of the truck 1 are fallen down on an unloading site 2.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a stationary vehicle tilting device used for unloading work of a freight vehicle that is not equipped with a load ejecting mechanism such as a dump mechanism.

In general, dirt, waste materials, and other garbage generated from construction sites are transported by truck to a designated dumping site and disposed of. At this time, if the truck is equipped with a cargo discharge mechanism such as a dump mechanism, the cargo is unloaded to a dumping site by the discharge mechanism.

By the way, in a freight vehicle that is not equipped with a cargo discharge mechanism such as a dump mechanism, a worker climbs onto the cargo box and unloads the cargo manually each time.

However, as mentioned above, freight vehicles equipped with a cargo discharge mechanism such as a dump mechanism can easily unload the cargo, but freight vehicles not equipped with a cargo discharge mechanism such as a dump mechanism In each case, a worker must climb onto the cargo box and unload the cargo manually, which is hard work and requires immeasurable effort.

. ° This invention was proposed in view of the above problem, and the technical means for solving this problem is to install a stationary vehicle tilting device at the unloading area, and this vehicle tilting device is installed at the unloading area. The structure of the device is to provide a tilting table near the unloading area with its tip pivoted so that it can be tilted by a dump cylinder, a wheel stop protruding from the top surface of the tip of this tilting table, and a wheel stop facing the A lock lever is provided on the tilting table so that it can be rotated by a lower cylinder.

If a stationary vehicle tilting device is installed at the unloading area, as in the above-mentioned technical means, unloading work will be made easier even for freight vehicles that are not equipped with a load ejection mechanism such as a dump mechanism. This solves the problem.

The drawings are schematic diagrams showing one embodiment of the stationary vehicle tilting device according to the present invention, in which (1) is a freight vehicle that is unloading cargo using the device of this invention, and (2) is a freight vehicle that is unloading cargo using the device of this invention. The unloading area (3) for unloading the cargo of the automobile (1) is a tilting platform with a car stop (4) protruding from the upper surface of the tip. 5) so as to be tiltable by a dump cylinder (6). (7) is a tilting table (3)
The lock cylinder (9) is a dogleg-shaped lock lever whose middle part is supported by a pivot (8), and is attached to the tilting table (3).
It is rotatably provided.

Next, the operating procedure of the apparatus of the present invention in the above configuration will be explained.

First, extend the piston rod of the lock cylinder (9) and rotate the lock lever (7) clockwise around the pivot (8) as shown in the figure by the two-dot chain line. , the table is lowered below the top surface of the tilting table (3). In this state, the freight vehicle (1) is carried backward onto the tilting platform (3) and stopped when the rear wheels hit the stop (4). After that, the piston rod of the lock cylinder (9) is moved back and forth, and the lock lever (7) is rotated counterclockwise in the figure with the pivot (8) as a fulcrum. Stand up as shown by the solid line, lock the rear wheels to the car stopper (4) with the lock lever (7), and place the truck (1) on the tilting platform (
3) Place it on top. In this way, when the truck (1) is placed on the tilting table (3), the piston rod of the tamp cylinder (6) is extended and the tilting table (3) is moved around the pivot (5) as the fulcrum in the figure. It rotates counterclockwise and tilts the tilting table (3) and the freight vehicle (1) placed on the tilting table (3) rearward and upward as shown by the two-dot chain line in the figure. As a result, the cargo of the truck (1) naturally falls due to its own weight and is unloaded at the unloading location (2). When the unloading of the freight vehicle (1) is completed, the piston rod of the dump cylinder (6) is retracted and the tilting table (3) is rotated clockwise in the figure about the pivot (5). The tilting table (3) and the tilting table (
3) Tilt the freight vehicle (1) placed a above it forward and downward to the original position shown by the solid line in the figure, and then release the lock cylinder (
The piston rod 9) is extended to lower the lock lever (7), and the rear wheels of the truck (1) are unlocked by the lock lever (7).

By the way, the above explanation describes the unloading work for a truck that is not equipped with a load ejection mechanism such as a dump mechanism, but in the case of a truck that is equipped with a load ejection mechanism such as a dump mechanism, it is necessary to Instead of operating the device, the cargo may be unloaded at the unloading location by operating the ejection mechanism installed on the truck.

In addition, when unloading using a freight vehicle equipped with an ejection mechanism,
For freight vehicles that dump cargo boxes and unload cargo, if the bollards (4) of the tilting platform (3) are high as shown in the figure, it will interfere with the dumping operation of the cargo boxes, so please set the bollards (4) appropriately. It would be better to make it possible to move up and down with the mechanism.

Since this invention provides a vehicle tilting device which is provided with a tilting platform having a protruding wheel stopper on the top surface of its tip that can be tilted by a dump cylinder, it is not equipped with a load ejection mechanism such as a dump mechanism. Loading and unloading work can be done easily even on freight cars, and the labor of the workers can be significantly reduced.
