The specific embodiment
As shown in Figure 1, mining inclined-drift rail safety automatic protection device has one to be used for providing the winch 2 of power and the speed detector 3 of detection winch speed to mine car 4.Upper end and place, bottom in inclined gallery all are equipped with stop device 5, and the stop device of upper end, inclined gallery is a normally off, and the stop device of lower end, inclined gallery is a normally open.A plurality of grid 6 of holding up traffic evenly are installed on the inclined gallery; The described grid 6 of holding up traffic are made up of the actuating unit 63 that is installed in grid frame 61 on the tunnel, inclined gallery, is installed in the gate 62 on the grid frame and is used for opening and closing shutter 62; It is the gate of circular arc that described gate 62 adopts the surface; When having an accident, gate 62 provides a buffering can for mine car 4, reduces the damage to mine car.Described actuating unit adopts winch, and the motor of winch is connected with PLC control box 1, accepts the executive command of PLC control box 1.An essential safe type all being installed near switch 7 and safety switch 8 on each grid 6 of holding up traffic, is a kind of sensors near switch 7, and the object in its energy perception certain distance scope is approaching, produces on-off signal.A PLC control box 1 is all installed at upper and lower end platform place in inclined gallery.PLC control box 1 is electrically connected with motor, speed detector 3, stop device 5, actuating unit 63 and the safety switch 8 of winch 2 respectively.Stop pull switch 10 along a plurality of urgency are installed on the wall of inclined gallery, urgency stops interconnecting by steel rope on the one hand between the pull switch 10, is electrically connected by in parallel on the other hand, and one of them suddenly stops pull switch and is electrically connected with the PLC control box.Mine car enters inclined gallery transportation the time should shift to an earlier date 10s and gives the grid start signal of holding up traffic that is installed on the inclined gallery, and the array that is installed in the inclined gallery grid of holding up traffic are opened and closed successively.The minimum mounting distance of grid in inclined gallery of holding up traffic should be the distance of mine car inclined gallery running velocity * 35～50s.Hold up traffic grid quantity and position come according to the on-the-spot tunnel gradient and length fixed.
As shown in Figure 2, electric part of the present invention by PLC control box 1, respectively with PLC control box 1 bonded assembly winch 2, speed detector 3, stop device 5, actuating unit 63, near switch 7, safety switch 8, urgency is stopped pull switch 10 and flame-proof type pressure transformer 11-2 forms.
Described speed detector 3 adopts the flame-proof type rotary encoder; Described flame-proof type rotary encoder 3 is installed on winch 2 flower wheels.Steel rope drives the flower wheel rotation by flower wheel; The flame-proof type rotary encoder calculates the speed of winch according to step-by-step counting.
Described weighting apparatus 11 comprises the Hydraulic Station 11-1 that is used to weigh, is connected the flame-proof type pressure transformer 11-2 that is used to gather the Hydraulic Station pressure signal with Hydraulic Station 11-1; Described flame-proof type pressure transformer 11-2 is electrically connected with PLC control box 1.The flame-proof type pressure transformer is passed to PLC with the signal of the pressure on the Hydraulic Station, and in allowed limits whether the weight that PLC judges mine car let pass if surpass setting value then do not allow, and then allows to let pass in the scope of setting.
Adopt essential safe type near switch near switch 7, the object in its energy perception certain distance scope is approaching, produces on-off signal.
Personnel positioning detecting device 9 is installed on the tunnel of inclined gallery, and described personnel positioning detecting device is connected with the PLC control box.Do not detect the pedestrian is arranged in the inclined gallery in conjunction with mine personnel positioning system, realize " the not pedestrian that drives a vehicle, the pedestrian does not drive a vehicle ".
Suddenly stopping pull switch 10 is installed on the wall along the line of inclined gallery and (People's Bank of China's ladder one side is arranged); about 1.5 meters a kind of devices that can produce on-off signal of highly installing; suddenly stop connecting with steel rope between the pull switch 10; adopt in parallel the electrical connection simultaneously; as long as once drawing steel rope to produce on-off signal; on-off signal send PLC, and PLC carries out and shuts down action.
Working process: the mine car for the treatment of injection is at first weighed by Hydraulic Station, send quantity of information to PLC by the flame-proof type pressure transformer again, after the PLC calculation process, compare with the value of setting, the PLC system lets pass under the not overweight situation of mine car, under normal operating speed, PLC system operation stop device falls, and mine car passes through, and can carry out the transportation of normal inclined gallery; Otherwise, the overweight PLC system of weighing locking; Can release if any specific (special) requirements.When mine car transports, surpass setting value, the grid closure of holding up traffic if detect the speed of winch in inclined gallery; Effectively prevent the generation of " amplifying sliding " accident.
