Abstract
The invention relates to a protective circuit of a mining scraper conveyor. The protective circuit of the mining scraper conveyor solves the problems that an SCD chain breakage protector does not have protective effect when faults such as chain floating, chain falling and tooth jumping happen to the scraper conveyor. The protective circuit of the mining scraper conveyor comprises a reset, a first proximity switch K1, a second proximity switch K2, a first intermediate relay, a second intermediate relay, a first time relay and a second time relay. The protective circuit of the mining scraper conveyor completely replaces the SCD chain breakage protector, protects the mining scraper conveyor when chain breaking, chain falling, tooth jumping and chain floating happen to the mining scraper conveyor, and increases safe operation factors of the scraper conveyor.
Description
Technical field
The present invention relates to coal mine scraper conveyor equipment technical field, specifically a kind of mine flight conveyer protective circuit.
Background technology
Traditional mine flight conveyer SCD break chain protector is arranged on the driven shaft of slat conveyer; when slat conveyer normally moves; its driven shaft together rotates with imput shaft; when chain rupture fault occurs; it is even zero that its output speed declines to a great extent; break chain protector detects output speed; when output speed is during lower than setting value (driven shaft normal speed 80%); break chain protector action; export an on-off signal, control drive motor out of service, send sound and light alarm simultaneously; thereby protection equipment, alert handling failure.But SCD break chain protector exists significant limitation, what cannot occur at slat conveyer floats chain, falls chain, plays a protective role while jumping the faults such as tooth.
Summary of the invention
The object of the invention is in order to solve above-mentioned problems of the prior art, and a kind of mine flight conveyer protective circuit is provided, this protective circuit floats chain at slat conveyer, falls chain, jumps tooth, chain rupture, the chain that falls, can play a protective role while jumping chain.
The present invention is achieved by the following technical solutions:
A mine flight conveyer protective circuit, comprises reset switch Reset, the first approach switch K1, the second approach switch K2, the first intermediate relay, the second intermediate relay, very first time relay and the second time relay; Wherein, the coil KA1 of the first approach switch K1, the second approach switch K2 and the first intermediate relay is composed in series the first branch road, and one end of the first branch road is connected with slat conveyer contactless switch return signal Return, the other end is connected with zero line N; The open contact KA1 ' of the first intermediate relay and the coil KT1 of very first time relay are composed in series the second branch road, and one end of the second branch road is connected with slat conveyer contactless switch return signal Return, the other end is connected with zero line N; The normally closed contact KA1 ' ' of the first intermediate relay and the coil KT2 of the second time relay are composed in series the 3rd branch road, and one end of the 3rd branch road is connected with slat conveyer contactless switch return signal Return, the other end is connected with zero line N; Open contact KA2 ' one end for the second intermediate relay is connected with slat conveyer contactless switch return signal Return, the other end is connected with digital quantity input module DI; Another open contact KA2 ' ' of the second intermediate relay, the open contact KT1 ' of very first time relay and the open contact KT2 ' of the second time relay compose in parallel parallel branch, the coil KA2 of reset switch Reset, parallel branch and the second intermediate relay is composed in series the 4th branch road, and one end of the 4th branch road is connected with live wire Y2, the other end is connected with zero line N.
During use, protective circuit of the present invention is arranged on slat conveyer, as shown in Figure 1; specifically on two, slat conveyer great wheel 50CM place guide rail, each makes a call to an aperture; 1 approach switch K1 and K2 are respectively installed in two apertures, then use resin shutoff, by Fig. 2 wiring.
(1) while floating chain, jumping tooth; scraper plate is crooked; the first approach switch K1, the second approach switch K2 are elongated opening time while; the coil KA1 adhesive of the first intermediate relay; the coil KT1 time closing of very first time relay; the coil KA2 adhesive of the second intermediate relay, the digital quantity input module DI shutdown of reporting to the police.
(2) while falling chain, chain rupture, the first approach switch K1, the second approach switch K2 are failure to actuate, the coil KT2 time closing of the second time relay, the coil KA2 adhesive of the second intermediate relay, the digital quantity input module DI shutdown of reporting to the police.
(3) after operating personal trouble-shooting, manually by " Reset " push-button reset, starting outfit operation.
Protective circuit of the present invention has replaced traditional SCD break chain protector completely, and the perfect chain rupture of mine flight conveyer, falls chain, jumps tooth, floats the protections such as chain, has improved slat conveyer safe operation coefficient.
