The invention provides an encoder fixing device. The encoder fixing device comprises a first cross beam, a second cross beam, an encoder connecting plate fixed on the first cross beam, a housing, an elastomer installed inside the housing, a regulating lead screw, and a mandrel, wherein the housing is a structure of a bucket shape. One end of the elastomer presses against an inner wall on a closed end of the housing. One end of the mandrel is fixedly connected with the encoder connecting plate. The regulating lead screw is threaded with the second cross beam. The purpose of regulating an expansion amount of the elastomer is achieved by the regulation to the regulating lead screw, thereby achieving the purpose of relieving an impact force applied by a roller to the encoder, thus reducing errors in output pulse signals of the encoder, enabling speed feedback signals to be stable, removing faults such as uncontrolled speed and overspeed, as well as improving the safety. Meanwhile, the housing is the structure of the bucket shape with one end open, thereby the purpose of changing the elastomer therein can be achieved. Therefore, the cost is saved effectively.
Description
Technical field [0001] The invention relates to 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 of the mine main shaft, and this encoder is responsible for detecting speed and feedback speed in the automatic control system. [0003] During the use of the encoder, a rigid welded encoder bracket is required to fix the encoder in a suitable position so that the rubber ring of the encoder directly contacts the inner side of the hoist drum, so as to measure 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 Speed feedback signal, which will cause speed out of control, overspeed and other faults, affect...
