Description

{An apparatus for moving a roll plate of the container car}

The present invention relates to a roll plate elevating device of a container car bottom plate, and more particularly, to a container car bottom which can facilitate the movement of a container by allowing a roll plate having a plurality of rollers in which the container is slid to be lifted by a fluid. It relates to a roll plate lifting device of the plate.

Generally, a container car (CAR) refers to a vehicle that carries a container, and includes a cabin mounted at the front, a frame mounted at the rear of the cabin to load the container, and a container formed at an upper side of the frame. It is characterized by consisting of a bottom plate for loading. Accordingly, the present invention is an improvement of the bottom plate.

4 is a cross-sectional view illustrating a bottom plate of a conventional container car. First, the configuration thereof will be described below.

In the bottom plate 100 of the container car in which the plurality of recessed grooves 101 are formed in the longitudinal direction, the tube 200 is installed inside the recessed groove 101 to expand and supply air. The upper side of the tube 200 is characterized in that a plurality of rollers 301 is mounted is mounted on the roll plate 300 which can be elevated.

In addition, the tube 200 is equipped with an air supply unit that is separately mounted to the vehicle, which is composed of an air compressor, an air tank and a switching valve.

Therefore, when loading the container in the container car configured as described above, first, by supplying air to the inside of the tube 200 mounted in the recessed groove 102 of the bottom plate 100 to the tube 200 As it expands, the container is moved forward by the roller 301 mounted on the roll plate 300 by raising the roll plate 300 mounted on the upper side of the tube 200 of the recessed groove 102. Containers can be loaded from the front.

However, in elevating the roll plate through the tube as described above, by supplying air to the inside of the tube to raise the roll plate, by raising the roll plate through the air pressure is lowered the lifting pressure of the roll plate when moving the container The lower surface of the container had a problem such as close contact with the bottom plate.

In addition, by using the air pressure during the lifting of the roll plate, the load having an excessive weight also had a problem that can not be lifted.

Accordingly, the present invention has been invented to solve the above-mentioned problems, and as a result of raising and lowering a roll plate having a roller from a recessed groove through an actuator operated by a fluid, the rising pressure of the roller is kept constant at all times. An object of the present invention is to provide a roll plate elevating device for a container car bottom plate that can facilitate movement.

There is also an object to enable the movement of a load having an excessive weight by raising the roll plate with fluid.

The present invention for achieving the above object, in the container car having a bottom plate which is mounted on the upper side of the frame and a plurality of recessed grooves are formed in the longitudinal direction, the inclined portion one side is raised on the lower surface of the recessed groove Branches are formed with a plurality of protruding cam, the interior of the recess includes a plurality of moving rollers are moved through the actuator mounted on the front and mounted on the lower and the lifting roller mounted on the upper side The roll plate is mounted, and the cover plate is formed on the upper side of the roll plate to seal the upper portion of the recessed groove and a plurality of opening holes are formed so that the lifting roller can be elevated.

Hereinafter, with reference to the accompanying drawings the present invention will be described in detail.

FIG. 1A is an overall schematic view showing a container car of the present invention, and FIG. 1B is an enlarged cross-sectional view taken along the line A-A of FIG. 1A. First, its configuration will be described below.

In a container car having a bottom plate (1) is mounted on the upper side of the frame and a plurality of recessed grooves 11 are formed in the longitudinal direction,

The roll plate 4 includes a plurality of moving rollers 42 and a plurality of lifting rollers 41 are lifted through the actuator 3 mounted in front of the bottom plate 1 in the recessed groove 11. ) Is mounted.

Figure 2 is a partially exploded perspective view showing a bottom plate of the container car of the present invention, Figure 3 is a main portion of the present invention, the bottom surface of the bottom plate 1, the inclined portion 21 and the flat portion one side is raised A plurality of protruding cams 2 having 22 are formed.

The roll plate 4 is mounted inside the recessed groove 11, and is moved through an actuator 3 mounted at the front and mounted at a lower portion of the roll plate 4 to move along the protruding cam 2. The moving roller 42 and the plurality of lifting rollers 43 mounted on the upper side are included.

In addition, the cover plate 5 is formed on the upper side of the roll plate 4 to seal the upper portion of the recessed groove 11 and the plurality of opening holes 51 are formed so that the lifting roller 43 can be elevated.

This will be described in more detail as follows.

As shown in FIGS. 1 to 3, the roll plate 4 includes a body bracket 41 having a front portion connected to the actuator 3 and having an open top, and a lower plate 411 of the body bracket 41. ) The moving rollers 42 mounted in a number corresponding to the protruding cams 2, the lifting rollers 43 mounted at equal intervals on the upper side of the main bracket 41, and the main bracket 41. The upper plate 44 is formed of a plurality of holes 441 so that the upper portion of the lifting roller 43 may protrude while blocking the upper portion thereof.

The main body bracket 41 includes a lower plate 411, both side plates 412, and an upper bent plate 413, and the upper side of the both side plates 412 and the inside of the bent plate 413 at equal intervals. A plurality of open grooves 414 are formed, and the rotary shaft 431 is inserted into the open grooves 414 by forming a flat portion 432 on the rotary shaft 431 of the lifting roller 43. .

On the other hand, the actuator 3 mounted to the front of the roll plate 4 is characterized in that it is operated through a fluid supply unit 31 composed of a hydraulic tank 311, a hydraulic pump 312 and the switching valve 313. .

The actuator 3 is a double acting actuator in which two fluid lines are formed to move the roll plate 4 forward and backward.

Hereinafter, the operating state of the present invention configured as described above are as follows.

1 to 3, first, when the actuator 3 mounted on the front of the roll plate 4 is operated through the fluid supply part 31, the roll plate 4 is moved forward. As a result, the moving roller 42 constituting the roll plate 4 is moved along the inclined surface 21 of the protruding cam 2 so that the lifting roller 43 is raised.

That is, by operating the fluid supply unit 31 for driving the actuator (3) to move the roll plate (4) to the front and at the same time the moving roller 42 is located at the top dead center of the protruding cam (2), Lifting roller 43 which is pulled on the upper portion of the roll plate 4 is to protrude to the top of the bottom plate (1).

Therefore, when the lifting roller 43 protrudes to the upper side of the recessed groove 11, the roll plate 4 prevents the lowering of the roll plate 4 which is raised during movement of the container loaded as it is operated by the fluid. . Therefore, the container loaded in the container car can be moved with little force.

On the contrary, after the movement of the container is completed, as the actuator 3 is returned to its original position, the roll plate 4 is reversed again so that the roll plate 4 is formed in the bottom plate 1. As it is lowered and inserted back into the inside of the container, the loaded container can be set at an appropriate position.

The present invention as described above, by increasing the roll plate through the fluid stably to facilitate the movement of the container loaded on the container car, it is possible to minimize the loading cost of the container.

In addition, it is possible to move the load having an excessive weight by raising the roll plate to the fluid, thereby also having the effect of not receiving the weight constraints of the load.
