Anti-impact structure for transfer point chute of belt conveyor

Abstract

The invention relates to an anti-impact structure for a transfer point chute of a belt conveyor. According to the anti-impact structure for the transfer point chute of the belt conveyor, a guide groove plate and a transfer chute plate are matched to form a protection part, and then multiple anti-impact rollers on the protection part are matched to form a protection curved surface, so that a material falling parabolic curve of a transfer point is subjected to step-by-step direction adjustment, materials are guided, and matching with buffer springs is achieved to buffer and unload the impact force of the materials. The anti-impact structure is characterized in that the section of the guide groove plate is in an arc shape, one side of the transfer chute plate is connected with one side of the guide groove plate, the edge of the other side of the transfer chute plate and the edge of the other side of the guide groove plate are coplanar, and the guide groove plate is matched with the transfer chute plate, to form the protection part. The section of a supporting frame is in a U shape, the middle of the supporting frame is arranged on the outer side of the protection part, the two ends of the supporting frame penetrate through the protection part and extend to the inner side of the protection part, multiple buffer springs are arranged between the middle of the supporting frame and the protection part, and two buffer sliding rods are arranged at the two ends of the supporting frame respectively.

Description

technical field [0001] The invention discloses an anti-shock structure for a transfer point chute of a belt conveyor, relating to a structure capable of avoiding impact on the transfer point chute of a belt conveyor, and belongs to the field of coal mine equipment. In particular, it relates to a protective part formed by the cooperation of the guide groove plate and the transfer chute plate, and then a plurality of anti-impact rollers on the protective part are used to form a protective curved surface, so as to adjust the direction of the parabolic curve of the falling material at the transfer point step by step, thereby The anti-shock structure guides the material and cooperates with the buffer spring to buffer and unload the impact force of the material.

AI Technical Summary

Problems solved by technology

[0002] When the material passes through the reloading point of the belt conveyor, because it has a certain kinetic energy endowed by the belt conveyor, coupled with the increase in kinetic energy brought about by the drop of the reloading point, the material itself will have a relatively large impact force, especially the ore material. Not one has a sharp part, which is very easy to impact, wear and even damage the chute at the material transfer point. Usually, in order to protect the chute at the material transfer point, a liner is added to it for protection, but due to the protection of the liner Mostly, the material of the liner itself is used to improve the impact resistance. The impact force when the material is reloaded directly impacts the liner rigidly, so that the liner is easily damaged by the impact force of the material.

[0003] Notification No. CN108891842A discloses a rubber chute liner for impact-resistant self-cleaning material transfer point, which is composed of a rubber liner wall and a chute. It is characterized in that the rubber liner wall is composed of several rubber liners head to tail. Bolts are fixed on the chute wall; the rubber liner is a whole, made of high-performance rubber and reinforced fabric skeleton composite vulcanization, in the shape of a double H, including a bottom plate, a bearing plate and a connecting rib; the bottom plate Bolt holes are set on the top and fixed on the chute wall with bolts; the surface of the bearing plate is provided with groove patterns along the direction of the material, and there is a skeleton layer of aramid fiber mesh inside; the connecting ribs are connected between the bottom plate and the bearing plate. When preventing material impact, the impact force of the material directly acts on the surface of the lining plate, and the lining plate bears a large force and is easy to be damaged
