Abstract

The roller device of the auxiliary stress mechanism comprises a vertical plate and a roller, a front-back through connecting hole is formed in the upper portion of the vertical plate, an upper beam body protruding backwards is arranged on the upper middle portion of the rear side plate face of the vertical plate and below the connecting hole, and a guide body protruding backwards is arranged on the lower portion of the rear side plate face of the vertical plate. A plurality of roller mounting holes are formed in the guide body, the axes of the roller mounting holes horizontally extend front and back, the top and the bottom of each roller mounting hole are respectively provided with a top notch and a bottom notch which are through front and back, one roller is arranged in each roller mounting hole, the rollers are mounted on the vertical plate, and gaps are kept between the rollers and the roller mounting holes; the highest point of the idler wheel is higher than the top face of the guiding body, and the upper beam body, the idler wheel and the vertical plate part located between the upper beam body and the guiding body define a three-face surrounding structure with a backward opening. The device is used in an auxiliary stress mechanism, and is used for applying constant downward thrust to a walking system, so that the walking mechanism is always kept in a normal meshing state, and effective traction force is provided.

Description

technical field [0001] The invention relates to a roller device, which is mainly used on an auxiliary force-bearing mechanism used in conjunction with the track of a shearer traveling system. The auxiliary force-bearing mechanism can provide a constant downward force for the traveling system, so that the traveling mechanism can always maintain In the normal meshing state, the roller device is the part of the auxiliary force bearing mechanism that is in direct contact with the track. Background technique [0002] When the shearer guide shoe encounters a large amount of hard and difficult-to-break block rock environment, the walking system is easy to fail prematurely, especially the hardened layer of the guide shoe bottom hook wears rapidly, and the guide frame of the guide shoe wears too much. The normal meshing between the traveling wheel and the pin row cannot be guaranteed, which will eventually lead to a greatly weakened climbing ability of the shearer, which will serious...
