Description

Carrier roller bearing extractor Technical Field The utility model relates to the technical field of carrier rollers, in particular to a carrier roller bearing extractor. Background The carrier roller is a main vulnerable part of the underground belt conveyor, the rejection rate of the bearing is gradually increased year by year under the influence of the underground environment, a plurality of scrapped carrier rollers are damaged only by the bearing, and the processing and the assembly of the carrier roller are a complete production line, but the replacement of the bearing in the carrier roller still has low efficiency, and the replacement is difficult, the material is wasted and other reasons to give up the repair. At present, a more traditional and extensive mode is generally adopted when the inner bearing is replaced by the carrier roller with the damaged roller skin and the intact bearing, although the damaged bearing can be tried to be taken out, secondary damage to the bearing and other materials cannot be avoided in the taking-out process, so that a large amount of originally repairable carrier roller is abandoned due to the damage of the materials, or a large amount of manpower and material resources and labor and time are consumed when the bearing is replaced, the carrier roller repairing efficiency is low, the reutilization rate is low, and the production cost is increased. Disclosure of utility model The utility model aims to solve the defects that in the prior art, secondary damage to a bearing seat and other materials cannot be avoided in the process of taking out, so that the carrier roller repairing efficiency is low, the recycling rate is low, and the production cost is increased. In order to achieve the above purpose, the present utility model adopts the following technical scheme: a carrier roller bearing extractor comprising: A main clamp, wherein one side of the main clamp is hinged with an auxiliary clamp, and one side, far away from one end of the auxiliary clamp, of the main clamp is provided with a hook leg; The main clamp and the auxiliary clamp are provided with the same adjusting component, the adjusting component is used for adjusting the opening angles of the main clamp and the auxiliary clamp, the main clamp and the auxiliary clamp are further provided with a taking-out component, and the taking-out component is used for being matched with the adjusting component to take out the bearing. In one possible design, the adjusting component comprises a screw rod which is connected with the rear end of the main clamp in a threaded manner, an adjusting nut is fixedly arranged at one end of the screw rod, a strip-shaped hole is formed in one side of the auxiliary clamp, the other end of the screw rod penetrates through the strip-shaped hole and extends to the outer side of the auxiliary clamp, and a limiting block is fixedly arranged at one end of the screw rod extending to the outer side of the auxiliary clamp.
