Description
Technical field
The present invention relates to mine safety appliance, is test and the control system that is used for passive jack catch motor vehicle door arrangement.
Background technology
The inclined shaft rail is manned/and to carry an ore deposit mine car usually be that a main car drags three (or four) tank cars, by winch and be hooked on wire rope on the main mine car hitch and rise to mine car on the ground or put to the down-hole; But promoting and putting down in the process, if situations such as disconnected rope, unhook or motor brake inefficacy take place, mine car is just out of hand immediately, freely glides.Because its speed is fast, kinetic energy is very big, can cause great derailing accident, and property and workman's life security are caused very big threat.The anti-sport car problem of inclined shaft is a thorny problem of being badly in need of solution during mine is produced always.
Being used for the catcher testing and control project at present has: (1) by the operation conditions that mechanical device to test mine car is installed (as lance etc.), adopts the arrester or the net of keeping off a car to stop mine car in the tunnel; (2) the radar velocity measurement device is installed in the tunnel, is adopted the arrester or the net of keeping off a car to stop mine car.
TT﹠C system in the such scheme (1) is owing to be mechanical contact type measurement, and reliability is not high, and durability degree is bad, the radar velocity measurement device that uses in the scheme (2) costs an arm and a leg, equipment cost is not suitable for all mines than higher, and especially middle-size and small-size mine is transformed installation.
Summary of the invention
Purpose of the present invention is exactly to overcome the problem that existing Catcher for mine car TT﹠C system scheme exists, and a kind of Automatic Detection and Control is provided, and response fast is durable reliable, easy for installation, the mine running-resisting car TT﹠C system scheme that cost is low.
Concrete scheme of the present invention is: optoelectronic switch group test mine car speed is installed in the tunnel, at down-hole installation testing and action control cabinet, at the indoor installation PLC of aboveground winch (programmable logic controller) control cabinet, aboveground down-hole control cabinet is connected by the power line carrier switch, it is characterized in that: the described optoelectronic switch group of a. speed measuring device, comprise three pairs of optoelectronic switches that are arranged in parallel on the sidewall of tunnel, two pairs are positioned at the vehilce-blocking door upstream, the a pair of vehilce-blocking door downstream that is positioned at, height flushes with mine car vehicle body middle part, in order to prevent that the workman from walking about system is exerted an influence, be added with the filtering wave by prolonging time to the optoelectronic switch input signal in the system program, the vehilce-blocking door above and below is equipped with travel switch; B. described aboveground and down-hole control cabinet, aboveground control include control core PLC main frame, power supply, acoustic-optic alarm, reset button, the power line carrier switch of two transmission signals and the power line carrier switch of four acknowledge(ment) signals be totally six pairs of power line carrier switches, is connected with the PLC main frame; The down-hole control cabinet includes power supply, transformer, the relay and the contactor of control motor positive and inverse, manual operation button, the power line carrier switch of four transmission signals and the power line carrier switch of two acknowledge(ment) signals be totally six pairs of power line carrier switches, is connected with sensor; Aboveground and the power line carrier switch down-hole is tied by the power line in the mine.
This TT﹠C system judges by the speed that the test mine car by the optoelectronic switch group is whether it derailing accident takes place.Under normal operating condition, vehilce-blocking door is in normally off, and mine car is before the vehilce-blocking door time, and vehilce-blocking door rises, and after the whole mistakes of car were intact, vehilce-blocking door fell.Mine car is touched the time difference Δ T2 of two optoelectronic switches and PLC internal timing value Δ T1 carry out logic and relatively calculate, Δ T1 has the mine car speed of service upper limit to calculate.When timing value Δ T1 touched the time difference Δ T2 of former and later two optoelectronic switches greater than mine car, the speed that mine car is described was greater than speed limit, and system is identified as hypervelocity with it and has an accident, and door is not opened, and sends sound and light alarm; When timing value Δ T1 touched the time difference Δ T2 of former and later two optoelectronic switches greater than mine car, the speed that mine car is described was less than speed limit, and system is identified as mine car with it and normally moves, and vehilce-blocking door is opened, and mine car is let pass.In order to prevent the influence of each side disturbing factor, in the PLC mainframe program, designed software filtering.
Can stop action when outreaching with the bottom for vehilce-blocking door, column at vehilce-blocking door is installed two travel switches in two ends up and down, both use the interface down-hole control cabinet that inserts in parallel, judge that by internal processes vehilce-blocking door is in last position or at upper/lower positions.Consider the inertia of door, there is certain distance top and bottom that travel switch should leave door.
Down-hole and aboveground data electrification carrier switch transmit by the power line in the mine.
The present invention designs uniqueness, judge according to the speed of service of mine car reality whether mine car sport car takes place, make control become more scientific and reasonable, and can just can realize adjustment by regulating timing length in the PLC internal processes according to different barghs needs to retro-speed, system flexibility is better; In addition, the present invention uses PLC as control core, reliability height; Main Control Tank is arranged in aboveground, has avoided of the influence of down-hole adverse circumstances, long service life master control unit; Electrification line carrier system carries out the signal transmission, and cost is low, good economy performance; The part of detecting compact conformation, installing space is little, and applicability is strong.
The present invention is further illustrated below in conjunction with drawings and Examples.
