Description

Chain-based vehicle loader bottom plate shuttle structure

Technical Field

The present disclosure relates to an unloading technology of a vehicle loading bin, and more particularly, to a chain-based bottom shuttle structure of a vehicle loading bin, which moves forward and backward on the bottom of the loading bin using a chain to enable automatic unloading of cargo.

Background

In general, bulk cargo refers to dry bulk cargo (such as grains, wood, or ore) loaded in a loading bin in the form of particles or powder without being packed, or wet bulk cargo (such as petroleum) loaded in a tank of a ship or a vehicle in a liquid state without being put into a container.

In order to transport dry bulk goods, such as grain, grain husks or sawdust, onto a vehicle, a dumper truck is usually used.

In general, a dump truck is a cargo vehicle for transportation that unloads cargoes loaded in a loading box via a tail gate that is automatically opened by tilting the loading box mounted at the rear of the vehicle backward by a predetermined angle using a lifting device operated by hydraulic pressure, mainly for transporting soil, crushed stones, or rocks for a construction site.

In the unloading method of the dump truck, the loading container is lifted at a predetermined angle by the lifting device, and at the same time, some of the loaded goods are dumped little by little due to the change of the potential energy. When the goods are accumulated, they are gradually moved forward, and the packing box is inclined to the maximum extent to completely pour out the goods, thereby completing the unloading work. When the loading bin is lifted to the maximum angle, the center of gravity shifts to the rear, and at the same time, the dump truck may tip over due to the dumped cargo.

In particular, since the dump truck is a special vehicle having a very large weight, a large accident may be caused, and thus measures for preventing a safety accident need to be taken during the unloading of the goods.

Recently, since the number of packages increases due to the development of electronic commerce and the like, freight trucks equipped with a box for transporting packages are widely used. In order to load or unload the cargo into or from the freight vehicle, the worker repeatedly performs physical labor, which increases the working time and causes safety accidents.

Fig. 1 is a view illustrating a vehicle equipped with a chain-based bottom shuttle structure of a vehicle loading compartment according to the present disclosure, fig. 2 is a view illustrating an exit of the vehicle loading compartment of fig. 1, and fig. 3 to 7 are views illustrating the chain-based bottom shuttle structure of the vehicle loading compartment according to the present disclosure.

Referring to fig. 1 to 7, the vehicle 10 includes a driver seat at a front portion thereof, on which a driver sits, and a loading box 100 at a rear portion thereof, in which a loading space is defined to load goods.

A rear gate 110 is formed at an outlet of the loading compartment 100, and the rear gate 110 is folded up and down to be opened and closed. A chain-based shuttle structure 200 according to the present disclosure may be mounted on the bottom of the loading compartment 100.

The rear gate 110 functions as a door that closes the loading space of the loading compartment 100 and opens the exit by folding to discharge the goods. As shown in fig. 2, the tail gate 110 may be hinged to an upper end of an outlet of the loading bin 100 via an operation shaft so as to be folded up and down, and a hydraulic device 120 may be installed on the operation shaft to perform an automatic opening and closing operation by a length adjusting mechanism that adjusts a length by hydraulic pressure generated by the hydraulic device 120. The configuration of the tailgate 110 is not intended to limit the present disclosure and is intended to describe only one embodiment thereof.

A shuttle is a system that moves back and forth between two points. Herein, the shuttle moves forward and backward by means of the chains in the loading bin 100 to push the loaded goods toward the exit and discharge them, and then returns to its original position.

The bottom shuttle structure 200 of the loading compartment according to the present disclosure may include at least one chain 210, a driving part 230, a shuttle bottom plate 250, a partition plate 270, and a controller (not shown).

At least one chain 210 having a predetermined length is disposed on the bottom surface of the loading bin 100 and moves along the bottom surface while rotating. In one embodiment, two chains 210 may be arranged in parallel on the bottom surface of the loading compartment 100. The number of chains may be appropriately determined in consideration of the bottom area, the kind of goods, or the load.

A guide member 220 may be installed on the lower surface of the bottom of the loading bin 100 in the longitudinal direction thereof to prevent the chain 210 from drooping and guide the movement.

The driving part 230 is located at one side of the bottom surface of the loading compartment 100 and provides a driving force to rotate the chain 210. The driving part 230 may be installed on the bottom, opposite to the outlet of the loading compartment 100. In one embodiment, the driving part 230 may include a motor 231 and a driving shaft 233, and the driving shaft 233 rotates the chain 210 by a driving force supplied from the motor 231. Here, the motor 231 may use a hydraulic motor. However, without being limited thereto, any drive motor is possible as long as it can provide the drive force to the drive shaft 233. When the motor 231 is driven, the driving shaft 233 rotates in the same direction as the driving direction of the motor 231, thereby rotatably moving the chain 210.

The shuttle base plate 250 is linked with the chain 210 at both sides thereof and moves along the chain 210. The shuttle bottom plate 250 may move forward or backward by the rotation of the chain 210 to push the goods to the outlet of the loading compartment 100. The shuttle bottom plate 250 may be formed of a plate member having elasticity and a size corresponding to the bottom of the loading compartment 100. In one embodiment, shuttle base plate 250 may be made of a rubber material. However, not limited thereto, the shuttle floor plate may be made of a flexible material to rotatably move along the chain 210. A roller member 260 may be installed below the outlet of the loading bin 100 to rotate the shuttle base plate 250.

The roller member 260 includes a pair of rollers. As the rollers rotate, the shuttle bottom plate 250 passes between the pair of rollers. The roller member 260 is a driven shaft of a driving shaft 233 of the driving section 230, which is rotated by the motor 231, and rotates in cooperation with the driving shaft 233.

The partition plate 270 is fixedly coupled to one side of the shuttle base plate 250 together with one side of the chain 210, and the other side of the chain 210 is coupled to the other side of the shuttle base plate via a link member 280. One end of the shuttle base plate 250 may be fixedly fastened to the lower end of the partition plate 270 via a fastening member such as a bolt.

The partition wall plate 270 is vertically installed in the loading space of the loading compartment 100 to form a partition wall. The partition plate 270 may be connected to the chain 210 to move forward or backward in the loading space of the loading bin 100 as the chain 210 rotates. One end of the chain 210 is fixedly coupled to a rear surface of the partition plate 270 via the bracket 271, and a front surface of the partition plate 270 faces the outlet of the loading bin 100, so that a pulling force generated by rotating the chain 210 acts on the partition plate 270. In one embodiment, one end of the chain 210 may be integrally coupled with the shuttle bottom plate 250 and the partition plate 270. In another embodiment, one end of the chain 210 may be integrally coupled with one side of the shuttle base plate 250 or the partition plate 270, and may fixedly couple the shuttle base plate 250 to the partition plate 270. The shuttle bottom plate 250 and the partition plate 270 may move forward and backward in the loading space of the loading compartment 100 by a pulling force generated by the rotation of the chain 210. The partition plate 270 may be formed of an upper vertical surface and a lower inclined surface to be stably held in the loading space, and play for mounting the driving part 230 may be secured by the lower inclined surface.

The link member 280 may be formed of a metal plate, the other end of the chain 210 may be fixedly coupled to the link member by welding, etc., and the other side of the shuttle bottom plate 250 may be fixedly coupled to the link member by a fastening member 281 such as a bolt.

As shown in fig. 5, the stopping member 290 may protrude downward from the lower surface of the bottom of the loading compartment 100. The stopping member 290 determines the stop position when the shuttle bottom plate 250 located at the upper surface of the bottom of the loading compartment 100 rotates and moves to the lower surface of the bottom. The stopping member 290 is formed on the lower surface of the bottom portion adjacent to the driving portion 230 installed at the innermost position on the bottom portion in the loading compartment 100. Therefore, if the shuttle bottom plate 250 pulled by the chain 210 moves to the lower surface of the bottom of the loading bin 100, contacting the stopper member 290, the motor 231 stops driving to stop the rotation of the chain 210.

A controller (not shown) may fold the rear gate 110 of the loading box 100 by electrical connection through manipulation of a user to open the exit, and may drive the motor 231 of the driving part 230 to shuttle the bottom of the loading box 100 by rotation of the chain 210, thereby performing an operation of unloading the goods.

The operation of the chain-based bottom shuttle structure of the vehicle loading compartment according to the present disclosure configured as described above will be described below.

The loading box 100 of the vehicle is open at the top thereof to allow the cargo to be loaded into the loading space using heavy equipment such as a forklift, and the cargo may be transported with the open top of the loading box 100 covered by a cover or the like.

In the unloading operation for unloading the goods loaded in the loading bin 100, a rotational force is provided to the chain 210 via the driving part 230. The shuttle bottom plate 250 is linked with the chain 210 at both sides, so that the shuttle bottom plate 250 moves along the chain 210. The chain 210 may pull the shuttle bottom plate 250 forward or backward to transfer the goods loaded on the shuttle bottom plate 250 forward or backward on the bottom of the loading compartment 100.

The driving part 230 may transmit power of the motor 231 to the chain 210 via the driving shaft 233 to rotate the chain 210 and linearly and rotatably drive the shuttle bottom plate 250 linked with the chain 210 so that the goods placed thereon fall toward the outlet. When the chain 210 is rotated by the driving shaft 233 rotated as the motor 231 is rotated and the shuttle bottom plate 250 linked with the chain 210 is rotated along the roller member 260 positioned below the outlet of the loading box 100, the shuttle bottom plate moves to the lower surface of the bottom of the loading box 100. In other words, when the chain 210 rotates in the first direction in a state where the shuttle bottom plate 250 is located on the upper surface of the bottom of the loading box 100 to load goods thereon, a tensile force acts on the shuttle bottom plate 250 linked with the chain 210 by the link member 280, thereby moving the shuttle bottom plate 250 forward toward the outlet. At the same time as the shuttle bottom plate 250 moves forward, the partition plate 270 also moves to support the goods loaded on the shuttle bottom plate 250, thereby preventing the goods from moving backward. The movement of the shuttle bottom plate 250 is guided to the lower surface of the bottom of the loading compartment 100 by the roller member 260 positioned below the outlet, thereby causing the goods to freely fall toward the outlet. The link member 280 is pulled by the chain 210 to the opposite side of the outlet along the lower surface of the bottom of the loading compartment 100. When the link member reaches the installation position of the stopper member 290, the motor 231 is stopped to stop the movement.

When the goods are unloaded, the chain 210 is rotated in the second direction by the driving part 230, so that a pulling force is applied to the second side of the shuttle base plate 250, thereby moving the shuttle base plate 250 backward toward the inside of the loading compartment 100. Simultaneously with the backward movement of the shuttle bottom plate 250, the partition plate 270 is also moved, so that the shuttle bottom plate is moved to the upper surface of the bottom of the loading compartment 100 and returns to its original position.

Fig. 8 is a diagram illustrating a process of unloading cargo according to an embodiment.

Referring to fig. 8, when soil is loaded in the loading space of the loading bin 100, the chain 210 is rotated by the driving part 230 to pull the shuttle bottom plate 250 installed on the bottom of the loading bin 100 toward the outlet, thereby allowing the soil to freely fall through the outlet. At this time, the soil does not move to the inside of the loading compartment 100 by the partition plate 270 vertically installed at one side of the shuttle base plate 250, and thus, the soil can be discharged without remaining.

Although the present disclosure has been described with reference to the specific embodiments shown in the drawings, it will be apparent to those skilled in the art that the present disclosure may be changed and modified in various ways without departing from the scope of the description of the present disclosure in the appended claims.
