Belt slipping detecting method of belt conveyor and belt slipping detecting device of detecting method

Abstract

The invention relates to detection for belt slipping of a belt conveyor. A belt slipping detecting method of the belt conveyor includes the following steps that firstly, a roller and a support of thebelt conveyor are fixedly provided with detecting switches and stopping blocks; secondly, with rotating of the transmission roller rotates by one circle as a period, a time quantum t is set; and thirdly, output signals of the two detecting switches are monitored in real time, if the output signals sent by the detecting switches are not detected within the time quantum t, it is judged that belt slipping occurs. A belt slipping detecting device comprises the detecting switches, intermediate relays, time relays and an alarming device. Power is supplied to the detecting switches through a switching power source; one intermediate relay is connected in a loop of each detecting switch, and one time relay is connected in a control loop of each intermediate relay; control switches of the time relays are connected in parallel, and are connected into a control loop of a time delay relay; and a control output signal of the time delay relay is connected with the alarming device or a power-off control loop of the belt conveyor.

Description

technical field [0001] The invention relates to a detection method and a detection control device for belt slippage of a belt conveyor. Use the proximity switch to detect the running status of the conveyor drive roller. Background technique [0002] Belt conveyors are widely used in material transfer in fields such as agriculture, chemical industry, electric power, coal and mines. In order to prevent safety accidents caused by conveyor failures, technicians designed deviation protection and pull rope switch devices. However, during the operation of the conveyor, due to the difference in the state and moisture content of the material, sometimes the belt will be crushed, causing the belt to slip and not work. This situation will cause the machine head motor to drive the machine head drum to run idly, consuming electric energy for no reason. But it is important to note that if the belt stalls to cause material to accumulate, in different situations, different serious consequ...

However, during the operation of the conveyor, due to the difference in the state and moisture content of the material, sometimes the belt will be crushed, causing the belt to slip and not work

This situation will cause the machine head motor to drive the machine head drum to run idly, and consume electric energy for no reason.

But it is important to note that if the belt stalls to cause material to accumulate, in different situations, different serious consequences may occur

[0003] At present, technical personnel have proposed detection and alarm devices for belt slippage. The detection and judgment methods are different, and the product structures are also different, but most of them have complex structures and high costs.
