Belt offset detection apparatus

Abstract

A belt offset detection apparatus is characterized in that a first detection device and a second detection and a second detection device sharing the first detection device are correspondingly arrangedon a supporting rack; a first conduction roller and a second conduction roller are arranged on a rotating shaft of the first detection device and a rotating shaft of the second detection device in respective; the first conduction roller contacts with the left side of a belt and the second conduction roller has contact with the right side of the belt; transmission shafts equipped with a first bearing and a second bearing are disposed in holes of a housing; each transmission shaft is covered with one torsion spring; the left end of each torsion spring is fixed on the inner wall of the housing via a first screw; a right end of each torsion spring is fixed on each transmission shaft via a second screw; an angle sensor is fixed on an installation seat disposed in the housing in the right end via first bolts; two ends of a flexible coupler are assembled to the right end of the transmission shaft and the left end of a shaft of the angle sensor via a first pin roll and a second pin roll; anda housing cover is fixed on the housing via a second bolt, and then the belt offset detection device is formed.

Description

technical field [0001] The invention relates to a belt detection device, in particular to a conveyor belt deviation detection device. Background technique [0002] Belt conveyors are widely used in industrial fields, such as ports, docks, mines, electric power and metallurgy and chemical industries. The stable and reliable operation of the belt is the key, but during the operation of the belt, due to equipment manufacturing, installation, and uneven material distribution in the belt width direction, it is inevitable that the belt will deviate. Work is paralyzed. [0003] At present, the deviation detection methods of the conveyor belt mainly include: non-contact deviation switch detection, sensor non-contact deviation detection, angle sensor non-contact deviation detection, angle sensor contact deviation detection, etc. [0004] For example, the patent number is: 201520505161.6 utility model patent, which discloses a tape offset detection device. The stick is connected wi...

Problems solved by technology

[0005] The above detection methods have played a positive role in the deviation detection of the conveyor belt, but there are still some shortcomings in the detection device; the patent number is 201520505161.6, a belt deviation detection device, the detection device still has certain defects in structure , the connection between the angle sensor and the rotating shaft is a rigid connection, which is very easy to damage the angle sensor and does not have the function of self-protection. At the same time, it is easy to cause abnormal damage to the offset detection device, and even cause system failure to cause shutdown, which seriously affects the production efficiency of the enterprise.
