Abstract
The utility model relates to a head deviation-prevention position detector used for a coal cutter on a coal mine working face, which realizes the speed reduction and deviation control of the coal cutter at two ends of a scraper conveyer, is a part of a high-precision automatic control system of the coal cutter on a coal mine working face, and mainly solves the problems of realizing accurate and fast detection of the coal cutter at limiting positions at the left end and the right end of the conveyer, and the like. The coal cutter body and the scraper conveyer are installed with a magnetic sensor so as to realize detection on the limiting positions at the head of the scraper conveyer. The magnetic sensor is realized as follows: the coal cutter body is installed with a permanent magnetic limit switch to receive the head position signal of the scraper conveyer; and stainless steel magnetic steel is respectively installed at limiting positions at two ends of the scraper conveyer to emit the head position signal of the scraper conveyer. The head deviation-prevention position detector adopts the magnetic sensor with high accuracy, good stability and simple and convenient operation to detect the limiting positions at two ends of the scraper conveyer, thus well solving the problem of head deviation of the coal cutter, and improving the reliability and the stability of the control of the coal cutter.
Description
Technical field
The utility model relates to a kind of anti-position detecting device that slides down in termination that is used for the coal mine work area coalcutter, realizes deceleration and anti-the slide down control of coalcutter at the scraper conveyer two ends, is the part of the high precision in control system of coal mine work area coalcutter.
Background technology
Coalcutter is the nucleus equipment of fully-mechanized mining working, mainly realizes broken coal by walking about on the scraper conveyer and coalings.The positional information of coalcutter walking is to realize the key of coal mining, particularly work as coalcutter and run to two ends, transporter left and right sides extreme position, cause deceleration untimely if can't accurately judge positional information, the danger that slides down then appears easily, not only jeopardize miner's life security, and coalcutter weighs tens tons, underground equipment is limited, can't in time coalcutter be installed on the scraper conveyor, have a strong impact on the coal mining progress.
The utility model content
The purpose of this utility model is to provide a kind of anti-position detecting device that slides down in coal mine work area coalcutter termination that is used for, and mainly solves the problem that coalcutter in the past causes coalcutter to slide down owing to the two ends extreme position that can't accurately judge scraper conveyer.
The technical solution of the utility model is:
The anti-position detecting device that slides down in a kind of coalcutter termination is equipped with Magnetic Sensor on coalcutter fuselage and scraper conveyer, realize the detection of coalcutter termination extreme position.
Described Magnetic Sensor is at the fuselage of coalcutter magnetic limit switch to be installed, the tip position signal of reception scraper conveyer; Extreme position is installed the stainless steel magnet steel respectively at the two ends of scraper conveyer, the tip position signal of emission scraper conveyer.
The anti-position detecting device that slides down in described coalcutter termination, the stainless steel magnet steel is installed on the ledge of two ends, scraper conveyor left and right sides extreme position.
The anti-position detecting device that slides down in described coalcutter termination, magnetic limit switch is installed in the centre position of coalcutter fuselage.
The anti-position detecting device that slides down in described coalcutter termination, the distance of stainless steel magnet steel and magnetic limit switch is 0～130mm.
The beneficial effects of the utility model are:
1, the anti-position detecting device that slides down in the utility model coalcutter termination is placed on two ends, the scraper conveyer left and right sides respectively with two stainless steel magnet steel, sends magnetic potential and puts signal.
2, the anti-position detecting device that slides down in the utility model coalcutter termination, the anti-position probing that slides down in coalcutter termination is placed on the centre position of coalcutter fuselage with magnetic limit switch, receives magnetic potential and puts signal.
3, the anti-position detecting device that slides down in the utility model coalcutter termination has realized that coalcutter runs to the detection accurately and fast of two ends, transporter left and right sides extreme position, has avoided the anti-danger that slides down of coalcutter, has guaranteed miner's life security and ordinary production.
Description of drawings
Fig. 1 is the anti-position detecting device synoptic diagram that slides down in the utility model coalcutter termination.
Fig. 2 is the I place zoomed-in view of Fig. 1.
Among the figure, 1 coalcutter; 2 scraper conveyors; 3 stainless steel magnet steel; 4 magnetic limit switches; 5 ledges.
Embodiment
The utility model is placed stainless steel magnet steel and magnetic limit switch respectively at coalcutter fuselage and two ends, the scraper conveyer left and right sides, by placing Magnetic Sensor at coalcutter fuselage and scraper conveyer, realizes the detection of coalcutter termination extreme position.
As Fig. 1-shown in Figure 2, the anti-position detecting device that slides down in the utility model coalcutter termination mainly comprises: stainless steel magnet steel 3 and magnetic limit switch 4, stainless steel magnet steel 3 is installed on the ledge 5 of two ends, scraper conveyor 2 left and right sides extreme position, magnetic limit switch 4 is installed on the fuselage of coalcutter 1, and the distance of stainless steel magnet steel and magnetic limit switch is generally at 0～130mm.
In the utility model, two stainless steel magnet steel are installed in two ends, the scraper conveyer left and right sides respectively, are used to launch the tip position signal of scraper conveyer.
In the utility model, magnetic limit switch is installed in the centre position of coalcutter fuselage, is used to receive the tip position signal of scraper conveyer.
In the present embodiment, coalcutter is the MG500/1180-WD coalcutter, and scraper conveyor is the SGZ900/1050 scraper conveyor.
Detection principle of the present utility model is as follows:
When coalcutter 1 runs to two ends, scraper conveyor 2 left and right sides extreme position, magnetic limit switch 4 on coalcutter 1 fuselage receives the magnetic induction signal of stainless steel magnet steel 3, directly the tongue tube of adhesive magnetic limit switch 4 makes magnetic limit switch 4 be output as the 24V high level signal.When coalcutter 1 is not walked two ends, scraper conveyor 2 left and right sides extreme position, magnetic limit switch 4 on coalcutter 1 fuselage does not receive the magnetic induction signal of stainless steel magnet steel 3, the tongue tube of magnetic limit switch 4 is in off-state, and magnetic limit switch 4 is output as the 0V low level signal.The coalcutter primary controller detects by the high-low level to magnetic limit switch 4 output signals, judges the run location information of coalcutter, thereby whether slows down processing, realizes the anti-function that slides down of coalcutter.
The result shows that the utility model adopts degree of accuracy height, good stability, Magnetic Sensor easy and simple to handle to detect the two ends extreme position of scraper conveyer, has well solved the problem that slides down of coalcutter, has improved the reliability and stability of coalcutter control.
