Problems solved by technology

[0002] During the use of the scraper conveyor on site, due to the harsh environment and complex conditions, failures such as underspeed of the scraper machine, broken chain, plate tilt, loose chain, asynchronous or missing scraper often occur. These failures may lead to a series of serious ACCIDENT
[0003] The existing detection technology usually sends out a signal to prompt maintenance personnel or operators to carry out troubleshooting and recovery work after a serious accident occurs. It cannot give a reminder before a serious accident occurs, so not only cannot avoid the occurrence of the accident, but also requires a long time recovery process, seriously resulting in a shutdown of the

Embodiment Construction

[0012] Embodiments of the present invention are described below with reference to the accompanying drawings. figure 1 It is a composition and installation position diagram of a detection device according to an embodiment of the present invention. As shown in the figure, the detection device mainly includes a frame assembly 1, a signal processing device 2, two idler rollers 3 and two actuating swing rods 6 (referred to as swing rod A and swing rod B respectively). The frame assembly 1 is used to directly or indirectly carry various components. The two idlers 3 are arranged on the frame assembly 1 and can rotate independently around two corresponding horizontal rotation axes. The two horizontal axes of rotation involved lie on the same horizontal line. The two touch rockers are vertically and rigidly connected to the two rollers 3 respectively. Preferably, the two actuating swing rods are respectively placed at both ends of the corresponding idler rollers away from each other...

Abstract

The invention provides a scraper conveyor fault detection device, comprising a frame assembly, a signal processing device, two carrier rollers and two touch oscillating bars, wherein the two carrier rollers are rotatably arranged on the frame assembly and can respectively independently rotate around two corresponding horizontal rotating axes, and the two horizontal rotating axes are arranged on the same horizontal line; the two touch oscillating bars are respectively, vertically and rigidly connected to the two carrier rollers; when the fault detection device of the scraper conveyor is in a non-working condition, the two touch oscillating bars naturally fall under the action of gravity; when the fault detection device of the scraper conveyor is in a working condition, the two touch oscillating bars oscillate under the action of a scraper and can drive corresponding carrier rollers to rotate around respective rotating axes; and the signal processing device comprises two sensors, wherein the two sensors are respectively used for detecting rotating processes of the two carrier rollers to generate a detection signal. The invention also provides a corresponding scraper conveyor fault detection system and a scraper conveyor fault detection method.

Description

technical field [0001] The invention relates to fault detection of mine transportation and lifting equipment, in particular to fault detection of scraper conveyors. Background technique [0002] During the use of the scraper conveyor on site, due to the harsh environment and complex conditions, failures such as underspeed of the scraper machine, broken chain, plate tilt, loose chain, asynchronous or missing scraper often occur. These failures may lead to a series of serious ACCIDENT. [0003] The existing detection technology usually sends out a signal to prompt maintenance personnel or operators to carry out troubleshooting and recovery work after a serious accident occurs. It cannot give a reminder before a serious accident occurs, so not only cannot avoid the accident, but also requires a long time The recovery process seriously leads to production stoppage. Contents of the invention [0004] In order to overcome the above defects, the present invention provides a scr...
