Description

Lifting belt anti-slip roller structure

Technical Field

The utility model relates to a lifting belt technical field, in particular to gyro wheel structure that skids is prevented to lifting belt.

Background

The traditional elevator assembly structure consists of a head roller, an elevator belt tensioning mechanism, an elevator bucket and an elevator belt assembly. The periphery of the head roller is of a smooth and flat structure with an arc, and when the lifting belt assembly normally works, the lifting belt assembly needs to be delayed for 3-10 seconds due to unilateral load, and the lifting belt assembly stops after the material with the load on the single side is thrown up. If the operation in-process breaks down promptly, need promptly to stop the lifting machine, lead to the lifting belt because of unilateral heavy burden, appear that the lifting belt skids or the head gyro wheel reverses, finally lead to unilateral heavy burden material to flow backwards to the lifting barrel in, can not normally start operation work next time with lifting barrel stifled, need artificial clearance to operate again afterwards.

SUMMERY OF THE UTILITY MODEL

The utility model provides an among the correlation technique gyro wheel periphery be smooth, level and smooth structure of taking the circular arc, cause the elevator belt to skid easily and lead to the problem of material refluence jam lifting machine, a pulley structure that the elevator belt skidproof is proposed, through set up the elasticity step in gyro wheel body periphery, the elasticity step is when receiving pressure, the step can infinitely be close the smooth face of gyro wheel body with tension spring, let the winnowing pan smoothly pass through, pass through the back when the winnowing pan, owing to pressure has not been had, the step can be rebounded to initial position again by tension spring's elasticity, when the machine breaks down and needs emergency shutdown, if when leading to skidding because the unilateral load of lifting machine is too big, the bolt bottom of winnowing pan below can be blocked in the situation to this structure can make the elevator belt stop in this position, the material refluence jam lifting machine phenomenon that the elevator belt skidded and causes has been stopped.

In order to solve the technical problem, the utility model discloses a realize through following technical scheme: the utility model provides a gyro wheel structure that hoisting belt prevented skidding, includes the gyro wheel body, the periphery of gyro wheel body is provided with a plurality of elasticity steps.

Preferably, the elastic steps are arranged on the periphery of the roller body at equal intervals.

As an optimal scheme, the elastic step comprises a step and a tension spring, one end of the step is hinged to the roller body, the other end of the step is connected with one end of the tension spring, and the other end of the tension spring is connected with the roller body.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a set up elasticity step in the gyro wheel body periphery, the elasticity step is when receiving pressure, the step can infinitely be close the glossy face of gyro wheel body with tension spring, let the winnowing pan smoothly pass through, pass through the back when the winnowing pan, owing to not had pressure, the step can be kick-backed again to initial position by tension spring's elasticity, when the machine breaks down and needs emergency shutdown, if when leading to skidding because the unilateral load of lifting machine is too big, the bolt bottom of winnowing pan below can be blocked in the situation to this structure, thereby can make the lifting belt stop in this position, the material refluence jam lifting machine phenomenon that the lifting belt skidded and caused has been stopped.
