Description

Technical Field

[0001] The present invention relates to the technical field of conveying devices, and in particular to a cargo conveying device that is easy to maintain and a use method thereof. Background Art

[0002] A conveying device is a device used to transport goods. Generally, a conveying device uses a conveyor belt to move the goods. The conveyor belt is generally driven by a rotating wheel. When the rotating wheel and the conveyor belt are damaged and replaced, interference is likely to occur during replacement, making replacement troublesome because the rotating wheel and the conveyor belt work together.

[0003] The defects of the existing conveying device are:

[0004] 1. The prior art KR1020140042085A discloses a belt conveyor, which does not have a structure for facilitating the replacement of a rotating wheel. If the rotating wheel is damaged while driving the belt to move, the rotating wheel contacts the belt, and the belt easily hinders the replacement of the rotating wheel. Therefore, a cargo conveying device that is easy to maintain and can easily replace the rotating wheel is needed to solve this problem.

[0005] 2. The prior art KR1020120073522A discloses a belt conveyor, which does not have a structure that is convenient for replacing the belt. When the belt needs to be replaced, the friction between the belt and the rotating wheel exists, so the belt is generally tight. When the belt is tight, it is relatively troublesome to remove and install the belt. Therefore, a cargo conveying device that can change the tightness of the belt and facilitate the replacement of the belt and is easy to maintain is needed to solve this problem.

[0006] 3. The prior art KR1020120071579A discloses a belt conveyor. This technology does not have a structure for quickly aligning multiple rotating wheels with mounting holes so as to facilitate the rapid installation of multiple rotating wheels on the conveyor. Workers are required to manually replace and install the rotating wheels one by one, which is rather troublesome. Therefore, a cargo conveying device that is easy to maintain and can quickly align multiple rotating wheels with mounting holes on the conveyor is needed to solve this problem.

[0007] 4. The prior art CN103159019B discloses a cargo conveying device, which does not have a limiting structure. When a limiting structure is set on the conveyor, the existence of the limiting structure is likely to interfere with the staff in replacing belts and other components. Therefore, a cargo conveying device that has a limiting structure and avoids the limiting structure interfering with the staff in replacing belts and other components and is easy to maintain is needed to solve this problem.

The cargo conveying device that is easy to maintain according to claim 1, characterized in that: An electric telescopic unit (12) is symmetrically mounted on one side of the right angle plate (3), and the electric telescopic unit (12) is electrically connected to the control unit (22). A push rod (13) is mounted on the output end of the electric telescopic unit (12), and a connecting block (14) is mounted on the outer side of the push rod (13), and one side of the connecting block (14) is connected to one side of the movable plate (4), and a bolt (15) is installed through one side of the connecting block (14).

5. The cargo conveying device that is easy to maintain according to claim 1, characterized in that: An electric telescopic unit 3 (24) is symmetrically mounted on one side of the right angle plate 1 (1), and the electric telescopic unit 3 (24) is electrically connected to the control unit (22). A piston rod 3 (25) is mounted on the output end of the electric telescopic unit 3 (24), and a connecting block 2 (26) is mounted on the outer side of the piston rod 3 (25), and one side of the connecting block 2 (26) is connected to one side of the movable plate 2 (23), and a bolt 3 (27) is installed through one side of the connecting block 2 (26).

6. A method for using a cargo conveying device that is easy to maintain according to any one of claims 1 to 5, characterized in that: The method for using the cargo conveying device that is easy to maintain is as follows: S1, the motor (11) drives the conveyor belt (8) to move backward, thereby driving the goods on the conveyor belt (8) to move backward, and at the same time, the hydraulic telescopic unit 2 (30) drives the limit plate (36) to move downward to limit the two sides of the goods; S2. When the rotating rod 1 (5) and the rotating rod 2 (9) need to be replaced, the right angle plate 2 (3) is driven to move to the left by the hydraulic telescopic unit 1 (16), so as to facilitate the replacement of the rotating rod 1 (5) and the rotating rod 2 (9); S3. When the conveyor belt (8) needs to be replaced, when the right-angle plate (2) (3) moves to the left, the electric telescopic unit (12) drives the movable plate (4) to move backward, thereby loosening the conveyor belt (8), thereby facilitating the replacement of the conveyor belt (8); S4. When it is necessary to install the rotating rod 1 (5) and the rotating rod 2 (9) through the right angle plate 1 (1) and the movable plate 2 (23), the supporting plate (21) is driven to move upward by the electric telescopic unit 2 (20), so that the rotating rod 1 (5) and the rotating rod 2 (9) can be supported, so that the rotating rod 1 (5) and the rotating rod 2 (9) can be aligned with the holes on the right angle plate 1 (1) and the movable plate 2 (23).

7. The method for using the cargo conveying device that is easy to maintain according to claim 6, characterized in that: The S3 also includes the following steps: S31. When replacing the conveyor belt (8), the limit plate (36) is driven to move upward by the second hydraulic telescopic unit (30), thereby preventing the limit plate (36) from interfering with the staff.
