Abstract
A method is used for reducing the protection dead-zone of a normal-closed blocking column. The left end and right ends of the blocking column are connected through buffering ropes with buffers fixed on two sides of a lane. A retractable winch is driven by a monitoring speed-measuring device and an automatic control system to tow the blocking column through a traction rope so as to release or draw back the blocking column; and a releasing device used for releasing the traction rope instantaneously is arranged to lead the blocking column to fall freely and the length of the traction rope released instantaneously is not less than the release stroke of the blocking column. The releasing device is provided with a traction rope guide pulley and a releasing body; and a releasing actuation mechanism is arranged between the traction rope guide pulley and the releasing body and is connected with an automatic control system through an actuation circuit. When the blocking column is opened and the vehicle runs, the traction rope is released instantaneously to lead the blocking column to fall freely in the shortest time. Compared with the existing art, the method reduces the protection dead-zone and prolongs the effective protection distance as much as possible.
Description
Technical field
The present invention relates to the protection in a kind of slope rail transport, particularly a kind of method that shortens normally closed type tram guard protection dead area.
Background technology
In the slope rail transport, promote material along the track that lays in the inclined shaft by winch traction mine car.Promoting and transferring in the process of material, for various reasons, the mine car that may produce lifting breaks away from traction control.Mine car out of control rapidly glides along track, breaks the pit shaft facility, and causes great life to threaten to staff in the following parking lot.Therefore, derail avoidance is a very important safety measure.
In the immediate prior art of the present invention, as present common buffer stop: the patent No. be ZL200420098544.8, and the patent No. be the Chinese patent of ZL200620070130.3.Its principle of work is the normally closed buffer stop, arrester often is in closed condition, mine car is near arrester, the parking stall sensor arrives, and outputs signal to the arrester opening/shutting controller, and the control draw gear is opened arrester, mine car leaves arrester, the parking stall sensor arrives, and outputs signal to the arrester opening/shutting controller, and the control draw gear is closed arrester.It is reliable that such device opens and closes arrester, yet arrester has been opened a time course, mine car is descending near arrester, and this time course has caused tram guard protection dead area, causes lead big more slowly owing to open and close the speed of arrester, form bigger protection dead band, shortened effective protective range.
Summary of the invention
The technical problem to be solved in the present invention is at the deficiencies in the prior art, has proposed a kind of method that increases effective protection distance, shortens normally closed type tram guard protection dead area.
The technical problem to be solved in the present invention is achieved through the following technical solutions, a kind of method that shortens normally closed type tram guard protection dead area, the two ends, the left and right sides of described arrester are connected with the energy disperser that is fixed on the roadway both sides by the snub rope, drive releasing winch by monitoring speed measuring device and autonomous cruise speed system, releasing winch is realized the folding and unfolding of arrester by hauling rope traction arrester, be characterized in: be provided with one make the hauling rope abrupt release take off the branch device, realize that arrester falls by the free-falling body mode, the length of abrupt release hauling rope is not less than the stroke of transferring of arrester.
The technical problem to be solved in the present invention can also come further to realize by the following technical programs, taking off packing has installed the hauling rope leading sheave and has taken off the branch body, hauling rope leading sheave and take off to be provided with between the branch body and take off the branch actuating unit takes off the branch actuating unit and links to each other with autonomous cruise speed system by executive circuit.
The technical problem to be solved in the present invention can also come further to realize by the following technical programs, between above-mentioned arrester and energy disperser, be provided with the cover rod that hangs on the roadway top by lifting rope, the two ends of cover rod join by snub rope and energy disperser, are connected with connection cord between the two ends of cover rod and the arrester.
The technical problem to be solved in the present invention can also come by the following technical programs further to realize that described monitoring speed measuring device adopts radar velocity measurement sensor or two infrared pickoff or the two combination.
The present invention has added and has made arrester take off the branch device by what the free-falling body mode fell quick closedown, and this mechanism is by the control of monitoring speed measuring device.Sport car takes place when arrester is opened, and the monitoring speed measuring device sends overspeed signal and gives autonomous cruise speed system, takes off the branch actuating unit by executive circuit control and makes the hauling rope abrupt release, in the shortest time, arrester is fallen in the free-falling body mode.Compared with prior art, dwindle to greatest extent the protection dead band, increase effective protection distance.In the roadway of equal length, can reduce the platform number that protective device is set like this, increase safe range, save the substantial contribution input.
