Description
Technical field
The utility model relates in a kind of slope rail transport by winch traction mine car and promoting in the material process along the track of laying in the inclined shaft, the guard technology of derailing accident takes place, particularly a kind of novel normally closed buffer stop.
Background technology
In the slope rail transport, promote material along the track of laying 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 following yardman.Therefore, derail avoidance is a very important safety measure in mine.
Buffer stop is pressed the arrester mode of operation, is divided into Chang Kai and normally closed two kinds of main standards.
The arrester of buffer stop open in usual often is in open mode, and the sport car state sensor sends control signal when monitoring the mine car sport car, stops the control setup action and makes arrester pass through gravity or other external force quick closedowns.Such device advantage is: it is fast to close arrester speed, and maintenance is little.Shortcoming is: be difficult for to check, may be because of electric or mechanical breakdown, and cause that arrester can not quick closedown when sport car.
The arrester of normally closed buffer stop often is in closed condition, and the parking stall sensor near arrester, outputs signal to the start-stop system to mine car, and arrester is opened in control.The parking stall sensor is left arrester to mine car, outputs signal to opening/shutting controller, and arrester is closed in control.Such device advantage is: the keying position of arrester is reliable, and action is directly perceived.Shortcoming is: arrester is opened numerous frequency, causes the fault rate height, easily causes mine car to scrape net or the anti-accident of drawing, and is the key point that perplexs the colliery transportation at present.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of flexible operation, novel normally closed buffer stop that fault rate is low.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of novel normally closed buffer stop, be provided with arrester, arrester start-stop system and sport car state monitoring apparatus, be characterized in: the traction winch of mine car is provided with winch monitoring running state device, and winch monitoring running state device and sport car state monitoring apparatus join by control circuit and arrester start-stop system.
The technical problems to be solved in the utility model can also come by the following technical programs further to realize that the sport car state monitoring apparatus is by comprising that the sensor device that detects the mine car hypervelocity or detect car haul winch cable strained condition constitutes.
The technical problems to be solved in the utility model can also come by the following technical programs further to realize that winch monitoring running state device comprises winch start-stop signal circuit and manual control signal circuit in parallel.
Under the normal condition, when the car haul winch did not start, winch monitoring running state device was by control circuit control arrester start-stop system, and arrester is closed the obstruction state that is in; When the car haul winch started, winch monitoring running state device was by control circuit control arrester start-stop system, and the arrester start-stop system controls arrester and opens; Start at traction winch and to put in the car process, arrester is in the clearance state of opening always,
When the race accident took place, the sport car state monitoring apparatus detected the mine car sport car, sent closing signal by control circuit and gave the start-stop system, and the start-stop system controls arrester and in time closes the obstruction sport car.
The utility model compared with prior art, arrester is opened and closed by the control of winch start-stop signal or manual signal, opens when putting car, closes when not putting car, hoistman is opened arrester enough predicted times.And normally closed arrester of the prior art is opened when car is close to arrester, if et out of order is not opened, causes and scrapes the online story event.Can realize different distance control modes, send electricity as remote control signal as adopting winch, realize working unlatching arrester, come off duty and close, significantly reduce arrester and open number of times, probability failure significantly reduces, and has realized high current rate.Arrester is in open mode, and the function of closing once again when having sport car has solved the work dead band of normally closed buffer stop of the prior art and the contradiction that arrester is opened lead.Its flexible operation, fault rate are low.
