Steel wire liner conveyor belt joint sensing device

Abstract

The present invention discloses a steel wire liner conveyor belt joint sensing device which comprises a shell (4), a base (12), a screw rod (8), a magnet steel (10), a magnet steel fixing frame (9), ferromagnetic collector blocks (14, 16), and a Hall sensing module (15). Two ends of the screw rod are supported on the base through two fixed frames (5, 13) inner threaded holes. The magnet steel is installed on the magnet steel fixing frame. The screw rod goes through the threaded hole on the magnet steel fixing frame such that the magnet steel fixing frame can move along the screw rod. The ferromagnetic collector blocks are up and down distributed, the gap between the two ferromagnetic collector blocks is equipped with the Hall sensing module. The lower ferromagnetic collector block is installed on the base and is at the tail end of the screw rod. A magnetic line collector is formed by the upper and lower ferromagnetic collector blocks and the Hall sensing module. The shell is covered by the ferromagnetic collector blocks, the magnet steel and the base to be closed. A screw rod head (7) extends out of the shell and can be rotated and adjusted. The distance between the magnet steel fixing frame and the magnetic line collector can be adjusted by adjusting the screw rod head.

Description

technical field [0001] The invention relates to a detection device for a steel wire-lined conveyor belt, in particular to a sensor device for a joint of a steel wire-lined conveyor belt. Background technique [0002] The conveyor belt is the lifeline of the port area. For a busy ore transit port of an enterprise, the conveyor belt is loading and unloading iron ore from all over the world day and night. The conveyor belt has a wide surface, fast speed, long line and high carrying capacity. Larger, used conveyor belts are steel wire lined conveyor belts. According to the measurement of the wharf area, the length is nearly 1,000 meters, the circumference is nearly 2,000 meters, and the 2,000-meter steel wire-lined conveyor belt must be spliced ​​in sections according to the manufacturing process. The spliced ​​conveyor belt section is called "belt joint." ", generally speaking, a steel wire-lined conveyor belt with a circumference of 2000 meters is composed of nearly 10 "belt ...

AI Technical Summary

Problems solved by technology

In the past, the method of embedding magnetic nails in the "joints" of steel wire-lined conveyor belts has been used for identification, that is, the magnetic nails are embedded in the "joints", and then read by Hall sensors, but the recognition rate is not high, and the error rate is low. There are a lot of actions, the reason is that the magnetic nails are easy to fall off, lose their magnetism, and the Hall sensor is often deaf. In addition, there is no better way to support the identification technology
