The variable loading device 1 according to an embodiment of the present invention is a product capable of loading various types of vehicles by being installed on a loading means 41 provided in a transport equipment 40 such as a truck for consignment.

To this end, the loading device 1 according to an embodiment of the present invention may include at least one of the loading unit 10, the adjusting units 20a and 20b, and the variable unit 30.

The loading unit 10 is seated on the upper surface of the loading means 41 provided in the transfer equipment 40.

At this time, the loading means 41 is a well-known configuration, and a detailed description thereof will be omitted.

The loading unit 10 is deployed or returned to its original position by the deployment device 50 installed on the loading means 41 .

The loading part 10 is in a state as shown in FIG. 4 when it is not unfolded, and when it is unfolded, the entirety is inclined at a certain angle as shown in FIG. 9 .

In addition, the end of the loading part 10 faces the ground.

At this time, the end portion becomes the facing area 10a facing the ground.

At this time, the deployment device 50 may include a guide rail 51, a slide unit 52, a deployment cylinder 53, a belt and a tilt cylinder 55.

The guide rails 51 are formed as a pair of two and disposed to face each other.

The guide rail 51 is formed in a substantially 'c' cross-sectional shape, and a space in which the slide unit 52 slides is formed therein.

For example, a substantially central portion of the guide rail 51 may be axially fixed to an end portion of the loading means 41 .

Accordingly, one side and the other side of the guide rail 51 may be rotated in an up and down direction based on an axis.

As another example, bottom surfaces of the central portions of the bottom surfaces of the guide rails 51 may be connected through a single connection bar (not shown).

In addition, both sides of the connecting bar may be shaft-fixed to the end of the loading means 41 .

Therefore, the connecting bar may be rotated based on the axis, and thus the guide rail 51 may be rotated in the up and down directions based on the axis.

A support roller 512 may be formed on an outer surface of the guide rail 51 to minimize friction by supporting the bottom surface of the loading unit 10 to be deployed or returned to its original position.

That is, the support roller 512 smoothly guides the movement of the loading part 10 while being rotated in place by friction while the loading part 10 is deployed or returned to its original position.

The slide unit 52 may be formed in a substantially rectangular frame shape.

Rollers (not shown) that roll along the inner space of the guide rail 51 may be formed on both sides of the slide unit 52 at regular intervals.

The deployment cylinder 53 is a hydraulic cylinder in which a piston expands or contracts as hydraulic pressure is supplied or discharged, and its body is coupled to the right side of the slide part 52 based on FIG. It is coupled via the connection block 531 on the left side of

At this time, pulleys 532 are coupled to both sides of the connection block 531, respectively.

And, although not shown in the drawing, pulleys 532 (not shown) positioned on the same line as the pulley 532 are formed on both sides of the body of the deployment cylinder 53, respectively.

The pulley 532 of the body and the pulley 532 of the connection block 531 are connected to each other through one timing belt 54.

Any one of the pulley 532 of the body and the pulley 532 of the connection block 531 may be rotated in a forward or reverse direction by a motor (not shown).

When the pulley 532 rotates, the timing belt 54 may rotate while forming an endless track corresponding to the rotation direction of the pulley 532 .

Furthermore, a mounting hole 25b (not shown) mounted on the timing belt 54 may be formed on the bottom surface of the loading part 10 .

The loading part 10 operates integrally with the timing belt 54 by the mounting hole 25b.

The interaction of the deployment cylinder 53 and the timing belt 54 described above will be described below.

In the state shown in FIG. 6, when the piston advances (extends) and the slide part 52 advances in the direction of the cab 40a, the loading part 10 is seated on the upper surface of the loading means 41, and as shown in FIG. keep the state

Then, when the piston contracts (reverses) and moves the slide part 52 backward in a direction away from the driver's cab 40a, the loading part 10 is transported to a substantially central portion of the loading means 41.

Accordingly, the right area of the loading unit 10 protrudes outward from the loading means 41 .

In this state, when the motor rotates the pulley 532 clockwise, the loading part 10 is transferred to the right end of the slide part 52.

On the other hand, the inclination cylinder 55 is configured to incline the loading part 10 at a predetermined angle as shown in FIG. 7 .

The tilting cylinder 55 is a hydraulic cylinder in which a piston expands or contracts as hydraulic pressure is supplied or discharged. It is rotatably installed on a pair of pivot brackets 5111 formed on the installation bar 511 installed to connect.

7 shows a state in which the piston of the tilt cylinder 55 is raised and the guide rail 51, the slide part 52, the deployment cylinder 53, and the loading part 10 are tilted at a predetermined angle, FIG. 4 shows a state in which the piston of the tilt cylinder 55 is lowered so that the guide rail 51, the slide part 52, the deployment cylinder 53, and the loading part 10 are leveled.

The piston of the inclination cylinder 55 rises after the loading part 10 is completely moved to the right end of the guide rail by the timing belt 54, or the loading part 10 is moved by the timing belt 54. It can be raised while moving to the right end of the guide rail.

The control units 20a and 20b prevent the facing area 10a from causing friction with the ground while the loading unit 10 is being deployed, and the facing area 10a of the loading unit 10 is grounded without great friction or impact. It is a configuration that allows contact with

To this end, the control units 20a and 20b move the supporting means 21 in contact with the ground instead of the loading unit 10 before the loading unit 10 is fully deployed.

At this time, the control units 20a and 20b may be applied in at least one, and the drawing shows an example in which two are applied as a pair.

The supporting means 21 may be formed of a roller to help the deployment of the mounting unit 10 by minimizing friction with the ground.

2 shows an embodiment of the adjusting unit 20a, which may include an adjusting cylinder 21a and a moving unit 22a.

The control cylinder 21a is a hydraulic cylinder in which a piston expands or contracts as hydraulic pressure is supplied or discharged.

The moving part (22a) is coupled to the axis support means (21) at one end.

The moving part 22a advances when the piston of the adjusting cylinder 21a expands (advance), and transfers the supporting means 21 to the facing area 10a.

Conversely, when the piston of the control cylinder 21a is contracted (backward), the moving part 22a moves backward and moves the supporting means 21 in a direction away from the facing area 10a.

Meanwhile, FIG. 3 shows another embodiment of the adjusting unit 20b, and may include a motor 21b, a screw bar 22b, a moving guide 23b, and a moving unit 24b.

The motor 21b is coupled to the lower surface of the loading unit 10 and may be formed of an AC motor or a DC motor and a hydraulic motor in which a motor shaft rotates in a forward or reverse direction.

The screw bar 22b is formed in a bar shape having a certain length, and a spiral for moving the moving part 24b is formed along the longitudinal direction.

The screw bar 22b may be rotated in a forward or reverse direction by the power of the motor 21b.

A plurality of moving guides 23b are applied and installed on the lower surface of the loading unit 10 at regular intervals.

The moving guide 23b is formed in a shape surrounding the top and both sides of the moving part 24b based on FIG. 3, and guides the moving part 24b to move without rotating in place.

That is, the movement guide 23b is such that the rotational action of the screw bar 22b is applied to the moving part 24b as a movement action.

The moving part (24b) is coupled to the axis support means (21) at one end.

A mounting hole 25b mounted on the screw bar 22b is formed on one side of the moving part 24b.

A spiral hole fastened to the screw bar 22b is formed in the mounting hole 25b.

With this configuration, the supporting means 21 advances according to the direction of rotation of the motor 21b and moves forward toward the facing area 10a of the loading unit 10 or moves backward to return to its original position.

That is, when the motor 21b is rotated in the forward direction, the moving part 24b is gradually moved to the right of the screw bar 22b so that the supporting means 21 is transferred to the facing area 10a, and the motor 21b is moved in the reverse direction. When rotated as , the moving part 24b is gradually moved to the left side of the screw bar 22b so that the supporting means 21 moves away from the facing area 10a.

The control units 20a and 20b described above are performed before the loading unit 10 is deployed, that is, before the deployment cylinder 53 and the timing belt 54 operate, or when the loading unit 10 moves the deployment cylinder 53 and In the process of being deployed by the timing belt 54 , the supporting means 21 may be transferred to the side of the facing area 10a of the loading unit 10 .

Meanwhile, the variable unit 30 is configured to adjust the height and inclination of the loading unit 10 by rotating the guide rail 51 in an upward or downward direction in a manner of elevating and lowering the guide rail 51 .

To this end, the variable parts 30 are composed of two pairs and coupled to one side of each guide rail 51 .

The variable part 30 may include a variable cylinder 31 , a support 32 and a seating part 33 .

The variable cylinder 31 is a hydraulic cylinder in which a piston expands or contracts as hydraulic pressure is supplied or discharged, and its body is coupled to the right end region of the guide rail 51 based on FIG. 5 . Then, the piston of the variable cylinder 31 faces the ground.

The support 32 is coupled to the guide rail 51, and is connected to the piston of the variable cylinder 31 through the medium of the lifting guide 321 and the connecting member 322 spaced apart from the variable cylinder 31 at a predetermined interval to form a variable cylinder ( 31) includes a support 32 including a lifting unit 323 that is lifted and operated by driving.

The elevating guide 321 has a tubular structure with an open bottom and an empty space inside, and the elevating part 323 moves the inner space of the elevating guide 321 as the piston of the variable cylinder 31 rises and falls. rises and falls along

The connecting member 322 may be formed in a cross-sectional shape of a 'c' shape when viewed from a plane.

A portion of the connecting member 322 is coupled to cover the lower side of the lifting part 323 and the lower side of the piston jointly.

The seating portion 33 may be formed of a roller and may be rotatably coupled to the inner space of the connecting member 322 .

A portion of the seating portion 33 protrudes downward from the connecting member 322, and is seated on the ground when the elevation portion 323 descends.

The aforementioned adjusting cylinder 21a, the motor 21b, the variable cylinder 31, and the deployment cylinder 53 and tilt cylinder 55 of the deployment device 50 may be operated remotely by a single remote controller. can

That is, buttons capable of individually controlling the control cylinder 21a, the motor 21b, the variable cylinder 31, the deployment cylinder 53, and the tilt cylinder 55 are provided on the remote controller.

Therefore, the manager can deploy the loading unit 10 or seat it on the loading means 41 through buttons on the remote control.

Next, the operation of the above-described loading device 1 and the unique effects appearing in the process will be described.

First, when the loading unit 10 is to be deployed in the state shown in FIG. 4, the support means 21 is moved by driving the adjusting cylinder 21a of the adjusting unit 20a or the motor 21b of the adjusting unit 20b. It is transferred to the facing area 10a, which is the right end of the loading part 10.

Thereafter, the lifting part 323 is lowered through the variable cylinder 31 to lower the seating part 33 .

At this time, when the seating part 33 contacts the ground, since the guide rail and the slide part 52 cannot be rotated downward, the seating part 33 is lowered through the variable cylinder 31 and It is designed to be spaced about 5 cm to 15 cm apart.

After that, the piston of the deployment cylinder 53 moves backward.

When the piston of the deployment cylinder 53 moves backward, the slide part 52 protruding outward from the guide rail 51 is accommodated inside the guide rail 51, and thus on the slide part 52 via the chain. The positioned loading part 10 is moved to an approximate central portion of the loading means 41 as shown in FIG. 6 .

Thereafter, the loading unit 10 is moved to the right end of the slide unit 52 by driving a motor (not shown) that rotates the aforementioned pulley 532 to rotate the timing belt clockwise.

At this time, after the loading part 10 is moved to the right end of the slide part 52 or in the process of moving the loading part 10 to the right end of the slide part 52, the piston of the tilt cylinder 55 it rises

Therefore, as described above, since the guide rail 51 is axially coupled to the end of the loading means 41, when the piston of the tilting cylinder 55 is raised, the loading part 10 has its left side relative to the axis. It rotates in an upward direction and its right side rotates in a downward direction. Due to this, the loading unit 10 is deployed in a form in which the facing area 10a is spaced apart from the ground at a predetermined interval while having a predetermined inclination as shown in FIG. 8 . In addition, in the process of deploying the loading unit 10, since the support means 21 rolls a certain distance along the ground, the deployment of the loading unit 10 can be smoothly performed, and the facing area of the loading unit 10 ( 10a) can be prevented from being damaged due to collision or friction with the ground.

On the other hand, after the loading unit 10 is deployed as shown in FIG. 9, the support member 21 is returned to its original position by driving the adjusting cylinder 21a of the adjusting unit 20a or the motor 21b of the adjusting unit 20b. In addition, the piston of the variable cylinder 31 is driven into the body of the variable cylinder 31.

In addition, when the variable cylinder 31 is operated, the piston is drawn into the body in a form in which the body of the variable cylinder 31 is lowered, so that the left part of the loading part 10 is further lowered, and eventually the facing area 10a as shown in FIG. As the left end of is in contact with the ground, the loading part 10 provides a gentle slope.

In this state, when the vehicle is driven and loaded onto the loading unit 10, it is possible to prevent the bumper of the vehicle from colliding with the loading unit 10, and to prevent the vehicle from shaking while riding on the loading unit 10. can be minimized

Moreover, when looking at the loading part 10 in the direction A of FIG. 5, the variable cylinders 31 are coupled to the loading part 10 so as to be spaced apart from each other in the left and right directions, and these variable cylinders 31 are individually controlled. implemented possible.

Therefore, when the ground is uneven and bumpy, the entire facing area 10a may not come into contact with the ground, and the left or right part may be spaced apart from the ground based on the perspective from the direction A of FIG. 5 .

Therefore, one variable cylinder 31 or two variable cylinders 31 corresponding to the spaced apart part of the facing area 10a is additionally controlled, that is, the withdrawal length or discharge length of the piston of the variable cylinder 31 is controlled. By adjusting, the entire end of the facing area 10a may be brought into contact with the ground. Accordingly, it is possible to stably load or unload the vehicle.
