The elevating means is provided with a plurality of cylinders (11) mounted on the inner side of the lower housing (10) and supported by a support bracket (13) and driven by the hydraulic force of the vehicle, and the rod of the cylinder ( 12 is fixed to the upper housing (20).

In addition, as a main configuration of the present invention, the door 30 and the door 30 for opening and closing the rear portion of the stacking box 1 is provided to slide along the rail groove (H) formed in the lower housing 10 and the upper housing 20; A pair of wires, one side of which is connected to the front part of the door 30 and supported by a plurality of rollers R to pivot the inside of the loading box 1, and the other side of which is connected to the rear part of the door 30 ( 31, wire winding means mounted on the inner side of the lower housing 10 so as to move the door 30 by winding the wire 31, and the upper housing with the door 30 stopped. And a wire length adjusting means for adjusting the spacing of the wires 31 to raise and lower the 20.

Here, the door 30 may be smoothly moved in the horizontal direction and the vertical direction along the rail groove H, and may be provided in a shutter shape so that it can be bent freely in a curved shape.

In addition, the wire 31 is connected to the front and rear portions of the door 30, respectively, as shown in Figs. 1 and 5, and inside the stacking box 1, that is, the lower housing 10 and the upper housing ( It is a state supported by a plurality of rollers (R) to turn to the edge of 20, the wire 31 to open and close the door 30 by pulling the door 30 to the front / rear side.

The wire winding means for providing a driving force to pull the wire 31, the forward / reverse rotation motor 40 is provided with a circular sprocket 41 on the rotating shaft, and the prime mover of the forward / reverse rotation motor 40 A driven sprocket 43 connected to the sprocket 41 and the chain 42 is provided on the shaft, and a pair of shaft rods 44 supported by bearings on the inner side of the lower housing 10 and a pair of shaft rods 44. And a drum 45 for winding one side of the wire 31.

When the forward / reverse rotation motor 40 is rotated in the forward direction, the shaft bar 44 and the drum 45 are integrally rotated, thereby winding the wire 31 so that the door 30 is rotated. By pulling the rear portion of the), the door 30 is moved to the upper housing 20 side in the opening direction, on the contrary, if the forward / reverse rotation motor 40 is rotated in the reverse direction the wire 31 is the Pulling the rear portion of the door 30 is implemented to move the door 31 toward the lower housing 10 in the sealing direction.

The wire length adjusting means is mounted inside the lower housing 10 and has a pair of brackets 51 having a through hole 52 formed at a central portion thereof, and the upper portion so as to be moved through the through hole 51 of the bracket 51. The first and second adjustment rollers (54) mounted on the inner side of the housing (20) and the brackets (51) and the frame (54) respectively correspond to the wires (31) to move in a pulley principle. 53,55).

The frame 54 is fixed to the upper housing 20 and is integrally operated. The distance between the first and second adjusting rollers 53 and 55 increases and decreases in proportion to the height of the upper housing 20. As a result, the length of the wire 31 is flexibly adjusted.

Here, as shown in FIG. 7, if the height change amount of the upper frame 20 is raised and lowered as ΔP, and the length change amount of the wire is ΔQ (L is the wire length corresponding to ΔP), The relation is established.

ΔP = L ---- (1)

ΔQ = 2L --- (2) ∴ ΔQ = 2 ΔP --- (3)

According to the relational expression, when the upper housing 20 is lifted by 1 m, the length change amount ΔQ of the wire 31 is 2 m, which is the wire (1 m high) by which the upper housing 20 is lifted. The distance 31 m is moved in the vertical direction and the upper housing 20 is the sum of the distances in which the wire 31 is moved 1 m in the horizontal direction so that the upper body 20 can be lifted up and down. Indeed.

The door 30 is installed in a “┑” shape in which the upper part is bent, and the horizontal direction of the length change amount ΔQ of the wire 31 is moved by 1 m so that the door (when the upper housing 20 is elevated) is moved. The bent upper portion of 30 may be unfolded in the vertical direction, thereby allowing the upper enclosure 20 to be smoothly lifted and lowered without interfering with the door 30.

As described above, the length of the wire 31 is flexibly adjusted according to the height change amount ΔP of the upper case 20, as shown in FIGS. 1 and 2, the door 30 of the stacking box 1. The upper housing 20 can be raised and lowered while keeping the rear portion sealed.

In addition, an open space may be formed in the rear portion of the stacking box 1 as much as the height of the upper box 20 is elevated. As the upper box 20 is elevated, the bent upper portion of the door 30 is opened. By unfolding vertically, it is possible to seal the open space naturally (see FIGS. 1 and 6).

On the other hand, the cylinder 11 for elevating the upper frame 20, the drive motor for rotating the roller installed in the horizontal direction on the inner lower portion of the loading box (1) and the forward / reverse rotation motor 40 is the operation switch (60) Driven by an electrical signal.

When explaining the operation and effect of the present invention configured as described above on the basis of the operating state of the loading box, first check the amount of the object to be loaded in the loading box (1) if the overload loading space of the loading box (1) widen In order to secure, the operation switch 60 is operated to drive the cylinder 11.

As the cylinder 11 is driven, the rod 12 is raised to raise the upper housing 20, and the frame 54 provided with the second adjusting roller 55 is also elevated. When the upper housing 20 is lifted to a height of 1m, the length change amount ΔQ of the wire 31 becomes 2m and moves by 1m in the vertical direction and the horizontal direction.

That is, as the upper housing 20 is elevated by 1 m, the wire 31 is moved 1 m in the vertical direction, and the banded upper portion of the door 30 is unfolded by the lifting operation of the upper housing 20. The wire 31 is moved 1m in the horizontal direction so that it can be.

Here, as the length of the wire 31 is properly adjusted according to the principle of the pulley, the lifting operation of the upper housing 20 is stopped at the bent upper part of the door 30 while the door 30 is stopped. Not only does not interfere smoothly, but also the open space formed in the rear of the stacking box (1) by the height of the upper housing 20 can be naturally sealed by the top of the door 30 is unfolded. It is.

Subsequently, when the operation switch 60 is operated to open the door 30 and the forward / reverse rotation motor 40 is driven to rotate in the forward direction, the shaft 44 is rotated through the chain 42. The drum 45 is wound around the wire 31 to move in the direction of W1-> W2, thereby pulling the rear part of the door 30 so that the door 30 moves along the rail groove H. The loading box 1 is opened by moving upward of the enclosure 20.

Subsequently, after the object is loaded in the loading box 1, when the forward / reverse rotation motor 40 is rotated in the reverse direction by operating the operation switch 60, the wire 31 is connected to the drum 45. W is moved in the direction of W2 → W1 while being wound, thereby closing the loading box 1 by pulling the front part of the door 30.

As described above, the operation of opening and closing the door 30 in order to withdraw the object after loading the object in the loading box 1 and transferring it to the destination is the same as the operation in the loading process, and the loading space is increased. The upper housing 20 is lowered by operating the operation switch 60 to drive the cylinder 11 to return the loading box 1 to the initial state.

In this case, when the height of the upper housing 20 is 1m, the length change amount ΔQ of the wire 31 becomes 2m and moves by 1m in the vertical direction and the horizontal direction.

That is, as the upper housing 20 is lowered to 1 m, the wire 31 is moved 1 m in the vertical direction, and the upper portion of the door 30 may be folded by the lowering operation of the upper housing 20. The wire 31 is moved 1 m in the horizontal direction so that the door 30 is lowered while maintaining the sealed state of the loading box 1.

As described above, the loading box 1 of the present invention is characterized by being able to easily secure the loading space by raising and lowering the upper housing 20 in a flexible manner, and having a shutter type in which the upper part is moved to bend. The lifting and lowering operation of the upper housing 20 can be performed smoothly without interfering with the door 30, and the upper housing 20 is formed at the rear portion of the loading box 1 as much as the lifting height. Since the upper part of the door 30 is opened by the lifting operation of the upper housing 20, the open space can be naturally sealed, so that it can provide convenience in use and reliability in operation. It is a useful design.

As described above, according to the present invention, the door of the loading box is provided with a shutter type that can be bent in a curved shape, and the loading and closing of the loading box can be easily opened and closed by operation of the forward / reverse rotation motor, thereby providing convenience for use. There is an advantage.

In addition, when the upper body is raised and lowered to secure the loading space of the loading box, the length of the wire is flexibly adjusted according to the principle of the pulley so that the upper body can be raised and lowered smoothly without interfering with the door. When the enclosure is lifted, the open space formed at the rear of the loading compartment can be naturally sealed by the door being opened by the lifting operation of the upper enclosure, thereby improving the operation reliability.
