Abstract

The invention provides an encoder fixing device. It includes: the first crossbeam, the second crossbeam and the encoder connection plate fixed on the first crossbeam; the casing, the elastic body arranged in the casing, the adjusting screw and the mandrel, wherein the casing is a barrel-shaped structure, and the elastic body One end abuts against the inner wall of the closed end of the shell, one end of the mandrel is fixedly connected with the encoder connecting plate, and the adjusting screw is threadedly connected with the second beam. Among them, the purpose of adjusting the amount of expansion and contraction of the elastic body has been achieved by adjusting the screw rod, so as to alleviate the impact force of the roller on the encoder, thereby reducing the error of the encoder output pulse signal, making the speed feedback signal stable, and eliminating speed out of control. Overspeed and other faults to achieve safety improvement. Moreover, the casing is a barrel structure with one end open, which can achieve the purpose of replacing the elastic body therein, effectively saving costs.

Description

technical field [0001] The invention relates to an encoder assembly technology, in particular to an encoder fixing device. Background technique [0002] There is a speed measuring encoder on both sides of the hoist drum in the main shaft of the mine. This encoder plays an important role in detecting and feeding back the speed in the automatic control system. [0003] During the use of the encoder, it is necessary to use a rigidly welded encoder bracket to fix the encoder in a suitable position, so that the rubber ring of the encoder is in direct contact with the inner side of the elevator drum, so as to achieve the function of measuring the speed of the drum. However, during the operation of the encoder, long-term contact with the roller can easily cause fatigue damage to the encoder bracket. Once the encoder bracket structure is unstable, the encoder output pulse signal will be lost, and the speed feedback signal will have serious errors or even no The speed feedback signa...
