Catch wheel device

Abstract

The invention provides a catch wheel device which has the advantages of simple structure, convenient installation and convenient maintenance and greatly lowers the manufacturing and maintenance cost. The catch wheel device comprises a baffle, a catch wheel axle and catch wheels, wherein the baffle is fixedly connected with a pedestal; the catch wheel axle is fixed on the pedestal; the catch wheels are rotatablely connected to the catch wheel axle through bearings; and a clearance, into which a wheel belt can be put, is respectively arranged between the baffle and the catch wheels. The catch wheels and the catch wheel axle form a bearing fit, thereby greatly reducing the wear of the catch wheel axle, greatly prolonging the service life and reducing the maintenance cost. The invention solves the problem of bouncing up by using the baffle structure, thereby saving one catch wheel set. By integrating the baffle with the catch wheels, compared with the structure with double catch wheels, the invention has the advantages of simple structure, convenient installation, convenient maintenance, easy replacement and the like.

Description

technical field [0001] The patent of the present invention relates to a stopper device, specifically, it is a mechanical device that restricts the positions of the equipment from moving downwards (moving the tilted rotary equipment to a lower direction) and moving upwards (moving the tilted rotary equipment to a higher direction) device. Background technique [0002] The retaining wheel device is mainly used on rotary equipment such as rotary dryers. Rotary dryer is an important auxiliary equipment for drying raw materials and auxiliary materials in the production of cement and chemical industry. The rotary dryer is a rotary cylinder supported by two supporting wheels. When the cylinder is installed, there is an angle of 2° to 4° with the horizontal plane, so there will be axial movement during the rotation process. When the movement reaches a certain When it is in the position, the dryer will be resisted by the retaining wheel and cannot continue to move. During the inst...

AI Technical Summary

Problems solved by technology

In the existing two-way retaining wheel, we will find that the upper shifting retaining wheel is in an idle state and rusts, which not only wastes manufacturing and installation costs, but also increases maintenance costs; The shaft sleeve is loosely fitted and in direct contact, and the wear is serious. The shaft sleeve needs to be replaced frequently. In severe cases, the retaining wheel and the retaining wheel shaft need to be replaced, and the maintenance cost is relatively high.
