Abstract
An NC-type retarder rail reverse opening and protection device belongs to an NC-type retarder rail reverse opening and protection device. The retarder protection device is characterized in that a down-travel retarder control sensor is arranged on the upper end of the NC retarder rail; an up-travel retarder control sensor is arranged on the lower end of the NC retarder rail; the other end of the NC retarder rail is overlapped on the retarder rail operation lever; meanwhile, the end of the overlapping end on the NC retarder rail is connected with an electric latch device; one end of the retarder rail operation lever is fixed; the other end is connected with an electrical push rod through a retarder rail operation rope; the guide rail is connected with the retarder rail operation lever; the guide wheel support is linked to the NC retarder rail; the guide wheel support is connected with the retarder rail guide wheel and the electric latch device. The utility model has the following advantages: 1. If the retarder rail cannot be switched on due to failure in sensors or operating devices, an mechanical device can be used to open the retarder rail. 2. The utility model is provided with double protections for mechanical and electric apparatus, so as to guarantee operation of the retarder rail. 3. In case of electric protection, the utility model can launch speech alarms and, simultaneously, control a winch to cut off the power source. 4. The utility model has the advantages of simple structure, convenient field operation and high practicability.
Description
Technical field
The utility model relates to a kind of, and particularly a kind of normally closed arrester is oppositely compeled out and fender guard.
Background technology
The arrester form that use inclined gallery, China's coal-mine down-hole has open in usual and two kinds of normally closeds, mode open in usual has mechanical mechanism controls and electromagnet mechanism control, misoperation often takes place or is failure to actuate when having an accident in arrester open in usual, is prohibited use by country.
At present, the normally closed arrester that people use is in closed condition at ordinary times, has only when vehicle passes through, and the mine car position detection control sensor of arrester is to vehicle, and the control motor-operating mechanism is opened arrester, and vehicle cuts out later; Mine car position detection control sensor has the position of using shaft encoder or use Programmable Logic Controller to calculate mine car, instructs electric pushrod to handle arrester then, realizes open and close.But when mine car position detecting device or any one generation fault of steering unit, arrester is not opened, mine car can directly bump against on the arrester, cause derailing accident if upwards the mine car that promotes can draw bad vehicle, break steel rope, violated the requirement that can not produce new hidden danger of installing and using of national relevant safety facilities.
Summary of the invention
The purpose of this utility model is to provide a kind of when mine car position detecting device or steering unit generation fault, prevents that arrester from missing the normally closed arrester of capturing vehicle and oppositely compeling out and fender guard.
The purpose of this utility model is achieved in that this fender guard of keeping off a car comprises electric pushrod, arrester operation rope, up arrester control sensor, descending arrester control sensor, electric blocking device, normally closed arrester, arrester control lever, guide rail, arrester track adjusting wheel and track adjusting wheel stand, in normally closed arrester upper end the descending control sensor of keeping off a car is arranged, the up control sensor of keeping off a car is arranged, the other end of normally closed arrester and arrester control lever overlap joint in the lower end of normally closed arrester; And be connected with the electric blocking device in the end of normally closed arrester lapped butt, arrester control lever one end is fixed, the other end is connected with electric pushrod by arrester operation rope, guide rail is connected the arrester control lever, the track adjusting wheel stand is connected on the normally closed arrester, is connected with arrester track adjusting wheel and electric blocking device on the track adjusting wheel stand.
The electric blocking device comprises control stay cord, stay cord track adjusting wheel and latch switch, and the control stay cord is connected with latch switch by the stay cord track adjusting wheel.
Beneficial effect, owing to adopted such scheme, when normal circumstances car group is passed through arrester, by control sensor or the control electric pushrod of keeping off a car, by arrester operation rope pulling arrester control lever, the arrester track adjusting wheel is opened arrester along guide rail movement, and the car group is closed by the back arrester; When vehicle detecting sensor or arrester steering unit fault; arrester can not normally be opened; on carry vehicle and promote the arrester control lever and push arrester open by guide rail, guide wheel; realize oppositely compeling out arrester; prevent to cause new accident, electric protective device sends arrester fault acousto-optic warning and reports to the police locking winch power supply simultaneously; realize the arrester fail safe, reached the purpose of this utility model.
Advantage: when 1, arrester was not opened because of sensor or operating control fault, this device for mechanical mechanism can self open arrester by the car group, prevented that the arrester mistake from capturing vehicle and causing the accident.2, machinery and electric two layers of protection are arranged, mechanical protection is guaranteed arrester work.3, electric protection is second layer when protection, and phonetic warning is reported to the police, and reminds hoistman, controls winch simultaneously and cuts off the electricity supply, and prevents that the arrester mistake from capturing vehicle and causing the accident.4, this apparatus structure is simple, and execute-in-place is convenient, and is practical, does not open because of arrester in the time of can effectively preventing the coal mine sloping lane tube-train hoisting and causes mistake to catch the generation of car accident.
