The safety control of inclined shaft (roadway) lifting transportation is achieved, great accident potential caused by falling off the roadway, breaking a rope, being overspeed and the like is avoided, and the requirement that the vehicle and people are not allowed to be in the inclined roadway at the same time is satisfied.
Description
Technical field
The utility model relates to mine safety controller, especially the people's air defense control device of transporting safely of inclined shaft, inclined gallery.
Background technology
Pedestrian walks track and the many dangerous phenomenons such as pedestrian of driving a vehicle determining very greatly to exist in degree for coal mine sloping lane transportation, and main fortune inclined gallery adopt tube-train hoisting or belt-conveying more simultaneously, once break down, pedestrains safety are constituted a serious threat.This system utilizes Programmable Logic Controller main frame, arrange that highdensity heat releases infrared sensor and outstation, pedestrian and tube-train hoisting or the belt-conveying situation of monitoring everywhere, inclined gallery, realize the omnidistance detection of high density, once when finding that there is in transit pedestrian's situation, sound and light alarm and send pedestrian's stop sign, guarantee to accomplish to drive a vehicle not pedestrian in the transportation of inclined gallery, the safety regulations requirement that pedestrian does not drive a vehicle.
Summary of the invention
The purpose of this utility model is for meeting < < safety regulations in coal mine > > requirement, provide the transportation safety of a kind of inclined shaft (lane) to control people's air defense device, the one, pedestrian's situation during controlling/monitoring inclined shaft (lane) transportation; The 2nd, control the safety door of inclined shaft (lane) and can not open when transportation promotes, prevent that pedestrian from entering in inclined shaft (lane); The 3rd, during puffer operation, safety door can not be opened, and prevents that pedestrian from swarming in inclined shaft (lane); The 4th,, personal information within showing screen display winch information and inclined shaft (lane) in real time.For achieving the above object, the utility model comprises the main frame consisting of Programmable Logic Controller, Monitor Sub-Station of Less and a peripheral circuit, and wherein Programmable Logic Controller is connected with peripheral circuit by the socket on casing, and wherein peripheral circuit comprises:
(1) safety door and the electromagnetic lock of inclined shaft haulage drift import and outlet are installed;
(2) the infrared emission sensor on tunnel safety door is installed;
(3) be arranged on the Monitor Sub-Station of Less of inside, tunnel;
(4) be arranged on the phonetic alarm device of inside, tunnel;
(5) be arranged on the hot type infrared sensor of inside, tunnel;
Above-mentioned peripheral circuit is connected on the input port of Programmable Logic Controller and outstation thereof successively;
Peripheral circuit also comprises:
(6) winch motor power supply relay, winch motor forward relay and winch motor reversion relay;
(7) the Host Security locking relay that programmable controller forms;
(8) display screen showing in real time.
The actuation coil of above-mentioned relay is connected on the delivery outlet of Programmable Logic Controller successively.
The utility model when work main frame is arranged in hoist house, above-mentioned peripheral circuit is connected errorless by socket, is electrified the work of getting final product, and principle of work is:
1,, when winch travels in tunnel, Programmable Logic Controller main website controls the anti-explosion electric magnetic padlock adhesive on safety door, from but safety door latch close, the pedestrian who wants to enter in inclined shaft (lane) cannot open safety door, has prevented swarming into of when driving pedestrian.2, when winch stops, the safety return circuit relay of Programmable Logic Controller main website disconnects, and anti-explosion electric magnetic padlock disconnects, and pedestrian can pass through in inclined shaft (lane), but winch cannot be opened because safety return circuit relay disconnects.3, system time detects the number in inclined shaft (lane), while having people in inclined shaft (lane) being detected, cannot open winch, and while having avoided having pedestrian, winch starts the hidden danger causing the accident.4, system is released infrared sensor by heat and is detected in real time the number in inclined shaft (lane), once there be people to avoid the infrared emission sensor of importing and exporting, enter in inclined shaft (lane), the uniform heat of high density is released infrared sensor can detect pedestrian information, and then send alerting signal, by audio alert, remind pedestrian and winchman, once at stop this hook of current operation of winch, winch is automatic blocking, cannot start winch, while only having nobody, putting can unlocking.
?the utility model has been realized inclined shaft (lane) and has been promoted the people's air defense control of transporting safely, can realize pedestrian monitoring, inclined shaft (lane) can not start winch while having pedestrian, and winch operation can not enter in tunnel by opening safety door time, and while having avoided driving, pedestrian swarms into inclined shaft (lane) and causes the accident.
