Description

Technical Field

[0001] The utility model belongs to the technical field of coal conveyor deviation correction, and more specifically relates to a coal conveyor roller belt deviation correction structure. Background Art

[0002] The coal transportation system is one of the indispensable infrastructures in power production, and the belt conveyor, as an important conveying equipment, is of great significance for improving production efficiency, ensuring production safety and reducing transportation costs.

[0003] However, during long-term, high-intensity operation of conveyor belts, deviation is a common problem. If deviation is not promptly addressed, it will seriously impact the stable and safe operation of the coal transportation system. Currently, the centerlines of the three rollers in the load-bearing roller frame are all aligned horizontally; the contact between the three rollers and the belt is a straight line, and the linear speed at the contact point is the same, making deviation prone to occur. Therefore, a coal conveyor roller belt deviation correction structure is urgently needed to solve this problem. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a coal conveyor roller belt deviation correction structure, which adopts forward-inclined conical rollers to achieve automatic belt deviation correction and ensure the normal operation of the belt.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the present utility model is as follows:

[0006] The coal conveyor roller belt deviation correction structure includes:

[0007] A crossbeam is provided with a middle roller, and forward-inclined side rollers are provided on both sides of the middle roller. The side rollers are installed on side roller frames, and the side roller frames are rotatably connected to the crossbeam. The side rollers are conical and the large ends are close to the two ends of the middle roller. The two side rollers can rotate synchronously.

[0008] As a further improvement to the present invention, the two ends of the side roller frame are respectively provided with a side roller upper mounting port and a side roller lower mounting port, and the side roller upper mounting port is further forward than the side roller lower mounting port on the vertical plane.

[0009] As a further improvement to the present invention, the middle roller is mounted on a stand, and the mounting opening of the stand and the lower mounting opening of the side roller are located in the same straight line.

[0010] As a further improvement to the present invention, the mounting opening of the stand, the upper mounting opening of the side roller, and the lower mounting opening of the side roller are all U-shaped openings.

[0011] As a further improvement to the present invention, the bottom of one side of the side roller frame is installed on the crossbeam through a rotating shaft, and a support frame is fixedly installed on the bottom of the other side of the side roller frame. A support wheel is installed on the crossbeam, and the support frame is against the support wheel.

[0012] As a further improvement to the present invention, the two rotating shafts are connected by a connecting rod assembly, and limiting bolts are provided on the beams at both ends of the connecting rod assembly.

[0013] As a further improvement to the present invention, the side roller includes a roller core and a roller sleeve, the roller core is in a truncated cone shape, and the roller sleeve is sleeved on the roller core.

[0014] As a further improvement to the present invention, the roller sleeve has a uniform thickness and is made of polytetrafluoroethylene.

[0015] The beneficial technical effects of the utility model are:

[0016] The utility model changes the installation slot position of the side roller. After the side roller enters the slot, it has a certain forward tilt angle, so that the contact line between the three-section roller body and the belt becomes a broken line, which plays an automatic deviation correction role, prevents the conveyor belt from running off, reduces material spillage, avoids conveyor belt wear and tear, and increases the service life of the conveyor belt.

[0017] The utility model will also be used in conjunction with a tapered roller. The speed of the end with a larger diameter is higher than that of the end with a smaller diameter, forming a resistance difference during the operation of the belt, which can be used to adjust the belt position and also play a role in correcting deviation.

[0018] The middle side roller of the utility model adopts a composite layer design, including a roller sleeve made of low-friction material, which can reduce friction, reduce energy loss, reduce equipment operation energy consumption, and meet green environmental protection requirements.
