Roller can ears you should know this knowledge

The roller tank ear is a kind of vertical shaft lifting container. Its structure consists of a base, a swing arm, a roller and a buffer. Combined with the characteristics of China's mines, it provides convenient conditions for the replacement of the new roller guide device for lifting vessels in operation at present, which is widely used in mining, coal and other industrial production sectors.

The roller can ears produced by our company adopt advanced sealing technology to adapt to the harsh environment such as water dashing and coal dust. The wheel head installation adopts three locking structure, completely avoiding the occurrence of wheel head accident. The roller is made of tetrahydrofuran-epoxy-propane copolymer polyurethane casting, which has the advantages of high elasticity, tear resistance, water resistance and oil resistance. Roller wear compensation adjustment adopts left and right screw, adjustment is quick and convenient. The frame and swing frame are welded by high quality steel plate, small in size, light in weight and easy to install.

Roller tank lugs are composed

Roller can ear is mainly composed of roller, bracket, spring buffer device, base, etc. The spring buffer device is composed of adjusting sleeve, adjusting screw, nut, disc spring shaft, guide sleeve, shunting cap, setting screw, disc spring, flat key, cylinder, etc.

The roller tank ear buffer device adopts a disc-shaped spring group, which conforms to the standard MT236-1991 of the coal department. Its principle of action is that the roller force is applied to the disc spring through the bracket, adjusting sleeve, adjusting screw and disc spring shaft, and the disc spring shaft is released and compressed by the upward and downward movement of the disc spring.

The disc spring shaft moves up and down in the guide sleeve and the guide hole at the bottom of the cylinder. The lower end of the disc spring shaft is milling with a keyway, and the disc spring shaft cannot rotate under the action of the flat key at the bottom of the cylinder. The guide sleeve screws into the cylinder and presses the disc spring shaft so that the shoulder of the disc spring shaft presses the disc spring. In order to be safe and reliable, the guide sleeve is used and the cap is locked, and the cylinder is matched with drilling and tapping, and the set screw is used for fastening.

Roller tank ear features

1, to replace the traditional buffer structure with hydraulic buffer, bearing capacity, stable operation, high reliability, long life, easy adjustment and maintenance.

2, the base and other parts are made of new materials, the overall structure has higher strength and strong impact resistance.

3. The buffer reset pressure is small, which can effectively avoid abnormal collision between the roller and the tank passage. It is transmitted to the shock absorber cylinder through the lever, and plays the role of guiding, buffering and stabilizing. The friction between the canisters and the lugs is changed from sliding friction to rolling friction, thus reducing power consumption, reducing noise, and significantly reducing wear on the canisters and lugs. Thus, the service life of the tank passage and the tank ear is improved.
