Abstract

PURPOSE:To simplify and facilitate unloading in a heavy cargo unloading bed for a truck by vertically moving the underside movable plate provided with metal balls relative to the upside bed plate provided with small through holes so as to protrude the balls from the through holes in transferring a load. CONSTITUTION:A bed plate 2 provided with numeraous small through holes 1 is secured fixedly to a rear body of a truck by a fixed plate 3 and a movable plate 5 is disposed right below said bed plate 2. Metal balls 4 fit rotatably in the small through holes 1 respectively and the movable plate 5 is moved vertically by a cam mechanism 6 such that the balls 4 enter and exit the small through holes 1. Thus, the cam 6 is rotated by a rod 7 advanced and withdrawn by a hydraulic cylinder 8, so that cargos can be shifted under the projecting condition of balls and cannot be shifted under the sinking condition to facilitate the unloading of cargo.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is effective when used for transporting or moving heavy objects, or for cargo, etc., but is particularly applicable to heavy object loading in freight vehicles. Concerning the improvement of a simple transport platform σ) that is useful for unloading cargo, etc.

<Conventional technology> Conventionally, small cranes have been used to load and unload single heavy objects on freight vehicles, etc., but this has limited space and
There are problems such as cent σ) and other troublesome installations.Currently, it is not practical and is not commonly used.

<Problems to be Solved by the Invention> Based on the above, the present invention is not limited to freight vehicles for transporting heavy goods, but is intended to solve the problem by simply renovating the loading platform of general freight vehicles. Even if I tried to grate it, it would be Q).

<Means for Solving the Problems> To explain the present invention with reference to drawings of embodiments, the present invention is applied to a loading platform of a freight vehicle, in which a loading platform plate (2 ) is fixed by a fixed plate (3), and a movable plate (5) is positioned directly below the movable plate (5) to which a ball (4) is attached so as to rotate in accordance with the position of a small through hole provided in the carrier plate. The movable plates (5) are all movable up and down by a cam mechanism, and all the poles (4) attached to the movable plates are connected to the loading platform plate (2).
) so that a part of the ball protrudes into and out of the plate surface through the entire through-hole (1) of γ and σ). However, the movable source for vertically moving the movable plate is a hydraulic cylinder (8) in Fig. 4.
) to the rod (by force.

This is done by a cam (6) connected to this rod.

Fig. 5 also shows the cam mechanism, but a movable plate (6) mounted on the cam (6) associated with the arrow-shaped σ cam mechanism (6) is shown in Fig. 5.
In 5), the movable plate is raised to a predetermined height using the inclined surface by the pressure of the arrow-shaped cam, and the ball attached to the movable plate is made to protrude from the small hole in the platform plate. Also, the one in Figure 6 has the same movable source as in Figure 5, but a continuous cam (
The ball (4) is installed on the γ-column (9), which is installed separately in front of the inclined surface of the cam (6).
) is lifted along the inclined surface of the cam to cause the ball to protrude from the through hole in the platform plate (0).

<Effects of the Invention> As described above, the present invention consists of a loading plate (2) having numerous through holes on the upper surface, and a movable plate having a ball attached to the lower side thereof so as to freely rotate.

This movable plate is lifted up by a cam operating mechanism, and when it is lifted, some of the metal balls of the movable plate protrude from the through holes. After that, heavy objects can be loaded from the rear or sides of a freight vehicle by freely and easily sliding it on the loading platform by the rotation of the ball, and when loading is completed, the cam mechanism is activated. When the movable plate is lowered by the operation of This is an ideal heavy object transport device that can be easily carried out by a combination of a ball-mounted movable plate and a cam operating mechanism that moves the movable plate up and down.

As shown in Fig. 2 σ), this device uses the entire loading platform, and in Fig. 3, a part of the loading platform is used as a transport platform for this device, and heavy objects are slid from the rear of the loading platform and transferred to the front. Loading can be carried out in sequence. Furthermore, this device can be effectively used for loading and unloading freight cars, foreign freight cars, heavy metal objects, cargo aircraft, etc.

Claims (2)

[Claims] (1) For loading heavy goods such as freight cars and other sliding type transport platforms, the upper fixed loading platform has numerous small through holes drilled in an orderly manner, and the small holes provided in the loading platform directly below the fixed loading platform. A movable plate fitted to the through hole is positioned so that a part of the metal ball protrudes from the small through hole and rotates freely, and the movable plate is moved by a vertical movement mechanism. A heavy object transport platform characterized by: (2) In the above-mentioned conveyance platform, the vertical movement mechanism of the movable plate provided on the lower side with respect to the upper fixed loading platform plate uses a cam mechanism, an air or hydraulic cylinder mechanism, etc. A heavy object transport platform according to scope 1.
