Abstract
This utility model relates to a protecting device for a scraper conveyer, which comprises an approach switch installation bracket which is installed on a scraper of the scraper conveyer and is in parallel with the scraper, two approach switches installed on the installation brackets and a control system connecting with the output of the approach switch, wherein the two approach switches detect signals and output impulse signals to the control system. This device can protect the scraper conveyer, reduce workers' labor intensity, promote production efficiency, ensure the safe and continuous production of enterprises and reduce accidents treatment time consumption.
Description
(1) technical field
The utility model relates to a kind of fender guard, especially a kind of fender guard that is used for slat conveyer.
(2) background technology
Slat conveyer is not only the major equipment that reaches aboveground defeated coal under the coal mine, but also is the orbit of coalcutter, is indispensable major equipment in the modernized coal winning technology.The slat conveyer regular meeting that is in operation scraper chain occurs and jumps at the sprocket wheel place that tooth, scraper chain slide down, scraper chain is disconnected and scraper plate takes off the chain fault, and these faults will cause slat conveyer to damage as in time finding and shutting down and handle, and produce and interrupt.And, be blank both at home and abroad at the automatic protection of slat conveyer, and the operation conditions of slat conveyer not only can not in time be found fault always by artificial supervision, causes industrial accident, and working strength of workers is big, production efficiency is low.
(3) utility model content
[problem that will solve]
The operation conditions that the purpose of this utility model is to lack automatic safety device, slat conveyer at slat conveyer always by artificial supervision, can not in time find shortcomings such as fault, working strength of workers is big, production efficiency is low, the fender guard of the protection slat conveyer that provides a kind of and strengthen the slat conveyer protection, reduce working strength of workers, enhance productivity.
[technical scheme]
Slat conveyer fender guard described in the utility model is comprising the scraper plate top that is installed in slat conveyer and parallel with scraper plate near the switch mounting bracket be installed on this mounting bracket two near switch and control system.Two outputs near switch are connected with control system separately, and two detect signal and output pulse signal to control system near switch.
Wherein, two near the line of centres preferred parallel of switch in the scraper plate of slat conveyer.
Described sensitive face near switch is 3～30mm place above scraper plate preferably.
Describedly be preferably Omron E2E-X18ME1 near switch.
Describedly be preferably the PLC control system with the control system that is connected near switch output.
[beneficial effect]
The advantage and the good effect of the utility model slat conveyer fender guard are: fender guard of the present utility model is installed on slat conveyer is helped protecting slat conveyer; reduce working strength of workers; enhance productivity; ensure enterprise security, produce continuously, reduce the processing time of equipment breakdown.
(4) description of drawings
Specify embodiment of the present utility model below in conjunction with accompanying drawing.
When Fig. 1 is the slat conveyer normal operation, the utility model slat conveyer fender guard scheme drawing.
When Fig. 2 is the slat conveyer malfunction, the utility model slat conveyer fender guard scheme drawing.
Among the figure: 1, near the switch mounting bracket; 2,3, near switch; 4, with the control system that is connected near switch output; 5, scraper plate.
The specific embodiment
Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
Near switch: Omron E2E-X18ME1;
Parameter: detect distance: 12mm, power line voltage: 24VDC, contact capacity: below the 200mA, answer frequency: 0.1KHz, action indicator: LED (redness).
PLC control system input: CVM1D PLC 24VDC direct current load module, model: C500-ID218.
Slat conveyer: SGW-150C,
Parameter: scraper chain pattern: bilateral chain, speed: 0.868m/s, flight pitch: 1024mm, scraper thickness: 50mm, intermediate channel width: 1.6m.
As shown in Figure 1, with two scraper plate 5 tops that are installed in slat conveyer near switch Omron E2E-X18ME1 2,3 usefulness mounting brackets 1, two sensitive face 15mm places above scraper plate 5 near switch Omron E2E-X18ME1 2,3, two near switch Omron E2E-X18ME1 2,3 on same line of centers and parallel with scraper plate 5, meet the 24VDC load module C500-ID218 of CVM1D PLC control system near the output of switch Omron E2E-X18ME1 2,3.
When slat conveyer normally moves, when scraper plate 5 ran near switch Omron E2E-X18ME1 2,3 positions, near switch 2,3 actions, indicator lamp was simultaneously bright, CVM1DPLC detects the pulse near switch Omron E2E-X18ME1 2,3 outputs, pulse width 57ms simultaneously.
As shown in Figure 2, scraper plate when taking off chain appears that scraper chain jumps at the sprocket wheel place that tooth, scraper chain slide down, scraper chain is disconnected and in slat conveyer, scraper plate 5 run-off the straights, when bevelled scraper plate 5 runs near switch Omron E2E-X18ME1 2,3 positions, two near not action simultaneously of switch Omron E2E-X18ME1 2,3, time difference 73ms, CVM1D PLC can not detect the pulse near switch Omron E2E-X18ME1 2,3 outputs simultaneously, after differentiating, the output control signal makes slat conveyer out of service.The utility model slat conveyer fender guard also can adopt other model near switch, but with the control system that is connected near switch output also other control circuit.
