A device for detecting the rotation angle of the middle groove of the scraper conveyor

Abstract

The invention provides a scraper conveyor middle trough rotation angle detecting device and belongs to the technical field of mechanical performance tests of coal mine machines. The device comprises an encoder, a telescopic rod, a spherical joint, a first fixing frame and a second fixing frame, wherein the encoder is fixedly installed on the first fixing frame and is vertically arranged, and a clamping sleeve is fixedly installed on a rotating shaft of the encoder; the telescopic rod is horizontally arranged, one end of the telescopic rod is fixedly connected to the clamping sleeve, and the other end of the telescopic rod is connected with the spherical joint; a sliding groove is vertically formed in the second fixing frame, the spherical joint is located in the sliding groove and can vertically slide along the sliding groove, and the spherical joint can freely rotate in the sliding groove. An absolute photoelectric encoder is adopted as the encoder, a first protective cover is arranged above the encoder, a second protective cover is arranged above the sliding groove, and the first protective cover and the second protective cover are arranged in a staggered mode in the vertical direction. The scraper conveyor middle trough rotation angle detecting device can be used for detecting the rotation angle of a scraper conveyor middle trough online in real time, and accurate rotation angle data are provided for technical staff for carrying on research.

Description

technical field [0001] The invention belongs to the technical field of mechanical performance testing of coal mines, and in particular relates to a detection device for a groove rotation angle in the middle part of a scraper conveyor. Background technique [0002] As an important transportation equipment for underground coal mining in coal mines, the scraper conveyor not only serves as the running track of the shearer, but also provides traction and guidance for the shearer, and at the same time provides a connection point for the hydraulic support, so that the hydraulic support and scraper The conveyor moves continuously along the advancing direction of the coal face. [0003] Since the scraper conveyor can be a bridge between the shearer and the hydraulic support, whether the scraper conveyor can run stably will directly affect the smooth progress of the coal mining operation. Testing the mechanical parameters of the scraper conveyor is an important means to study the mec...

Problems solved by technology

[0004] During the actual operation of the scraper conveyor, it was found that the middle groove of the scraper conveyor would be damaged due to excessive rotation angle. coal mining operations

For this reason, technicians urgently want to understand the relationship between the angle of rotation of the middle trough of the scraper conveyor and the degree of damage, but first they must accurately obtain the data of the rotation angle of the middle trough of the scraper conveyor. After a large number of technical searches, the technicians have not found a Existing means can satisfy the measurement of the angle of rotation of the middle groove of the scraper conveyor. Therefore, there is an urgent need for a device suitable for detecting the rotation angle of the middle groove of the scraper conveyor at this stage, so as to meet the needs of technicians for the measurement of the rotation angle data of the middle groove of the scraper conveyor. Urgent need for research
