Hammer shaft assembly system capable of monitoring bearing temperature of crusher

Abstract

The invention relates to a hammer crusher for a coal mine well, in particular to a hammer shaft assembly system capable of monitoring the bearing temperature of a crusher. In the prior art, since the running temperature of a bearing in a hammer shaft assembly can not be controlled, the bearing is damaged and cannot be used any longer within a short time because of poor lubrication and the deteriorated running status, resulting in the shutdown of the crusher. The hammer shaft assembly system capable of monitoring the bearing temperature of the crusher is characterized in that bearing blocks at two ends of the system are internally and respectively provided with a stepped long hole with a thread, the left end of a temperature fast-insertion sensor base is connected and fixed with the thread at the inlet of the stepped long hole of each bearing block, a probe is arranged in each stepped long hole, the upper part of an adapter substitute is inserted into a hole at the right end of the temperature fast-insertion sensor base and is fixed by a screw nail, the lower part of the adapter substitute is connected with a fast-insertion cable, the fast-insertion cable is connected with an electric liquid comprehensive monitoring system, and the electric liquid comprehensive monitoring system is fixed at a protective plate at the head of the crusher by a bolt. Therefore, operators can timely monitor the running of the crusher.

Description

technical field [0001] The invention relates to a hammer crusher device for underground coal mines, in particular to a hammer shaft assembly system capable of monitoring the temperature of the crusher bearing. Background technique [0002] The hammer shaft assembly is the core part of the hammer crusher. It is fixed on the frame of the hammer crusher through the bearing seat. The torque is transmitted to the hammer shaft by the motor through the transmission device. The hammer shaft rotates at a high speed, driving the hammer to crush the large coal Shock breaks into desired chunks. In the prior art, the operating temperature of the bearings in the hammer shaft assembly cannot be controlled. When the bearings are not properly lubricated or damaged due to deterioration of operating conditions, the temperature rise of the bearings in the hammer shaft assembly is abnormal or the temperature reaches an unacceptable high level, causing the bearings to It is scrapped in a short t...
