Abstract
The utility model discloses a normally closed anti-slip and pedestrian safety control device for inclined shaft comprising a carriage stopping protective device. The normally closed anti-slip and pedestrian safety control device for inclined shaft is characterized in that the normally closed anti-slip and pedestrian safety control device for inclined shaft also comprises a PLC controller (8), wherein, an electromagnetic type anti-slip device (3) is aranged at the rail of the inclined shaft at an interval; a magnetic couple is arranged on the electromagnetic type anti-slip device (3); the lower part of the magnetic couple is fixed with an electric magnet (2); the output terminal (B) of the controller (8) is connected to the coil of the electric magnet (2); the input terminal (A) of the controller (8) is connected to a detecting head of man carriage in and out tunnel (1); the input terminal (C) of the controller (8) is connected to a magnetic induction probe (6); the output terminal (D) of the controller (8) is connected to an electric relay (4); the output terminal (E) of the controller (8) is connected to a display (7). Adopting the structure, the normally closed anti-slip and pedestrian safety control device for inclined shaft can effectively obtain the integration of the anti-slip device and pedestrian safety control and the management automation of the safety in production for an incline shaft.
Description
Technical field
The utility model relates to a kind of safety of coal mines control device, more particularly, relates to anti-sport car of a kind of inclined shaft and pedestrains safety control device.
Background technology
According to present safety regulations in coal mine regulation, colliery inclined shaft (inclined gallery) must be installed the normally closed type catcher, so-called normally closed type is exactly that catcher is in blocked state constitutes always, that is: in inclined shaft, whenever keep at a certain distance away one group of protector of keeping off a car is set, when mine car through the time device get out of the way the mine car process automatically, mine car is in the state of keeping off a car again through later, wire rope is out of control when having an accident, because of catcher is in the state of keeping off a car, mine car is stopped.At present, catcher mostly uses a mechanical lever to control the unlatching of stopper, and this mechanical type is easy to malfunctioning, causes the accident.In addition, safety regulations in coal mine is also stipulated the inclined shaft haulage drift not pedestrian that drives a vehicle, and promptly people and car can not be gone together, and is sought after a kind of automatic control in this case and satisfies the device that the pedestrian does not drive a vehicle and requires.
Summary of the invention
The purpose of this utility model provides anti-sport car of a kind of inclined shaft normally closed type and pedestrains safety control device, the safety requirements of not driving a vehicle when solving the malfunctioning easily problem of mechanical type catcher and satisfying the pedestrian.
For achieving the above object, the technical solution adopted in the utility model is as shown in Figure 1:
Find out that by Fig. 1 it is that input at the PLC controller is connected with magnetic strength detecting head and people's car turnover tunnel detecting head, is connected with personnel's situation indicator, winch control relay and catcher at output to rise-falls to carrying out electrical equipment.
Wherein the magnetic strength detecting head is installed in winch drum wheel rim place, and with winch turn signal input controller, is used to measure the winch stroke; People's car turnover tunnel detecting head is installed in the tunnel import and export, it comprises a pair of common infrared tube and a thermal infrared spool, lead by separately is connected the controller input, be used for the identification personnel and pass in and out signal, with signal input controller, show by number in the controller calculating inclined shaft and by display; Personnel's situation indicator is installed in hoist house, grasps roadway number situation for drumman; The winch control relay is connected on the winch power supply patchboard.Man-hour is arranged in the tunnel, and the PLC controller is discerned the control relay automatic disconnection automatically has a power failure winch and braking, avoids the drumman maloperation to make winch continue operation; Catcher rises-falls to carrying out electrical equipment to be connected with the control device of car lug in the inclined shaft, and master controller sends the order of switching electricity according to the mine car travel of measuring to carrying out electrical equipment, thus the lifting or land of control catcher.
Adopt the good effect that technique scheme produced:
1. realized that with the modern programming controller anti-sport car control is integrated with pedestrains safety control, the inclined shaft production safety management is automatic
2. safe and reliable with the action of rising and falling of carrying out the electrical equipment control catcher, anti-derailing accident takes place.
3. satisfied not pedestrian's the safety management requirement of inclined shaft middle rolling car.
Description of drawings
Fig. 1 is the control device structural representation.
Among the figure: the side head is visited in 1-people's car turnover tunnel, the 2-catcher plays-fall electromagnetic block, 3-electromagnetic type catcher, 4-relay 5-winch, 6-magnetic strength probe, 7-personnel situation indicator, 8-PLC controller
Application principle below in conjunction with 2 couples of embodiment of the present utility model of accompanying drawing is described:
Be mounted on people's car turnover tunnel of importing and exporting in the tunnel at the input A of PLC controller 8 and visit side 1, lay electromagnetic type catcher 3 in the certain distance of inclined shaft orbital spacing, the magnetic couple below fixed electromagnet 2 of device, the output B of PLC controller 8 is connected on the coil of electromagnet 2, the input C of PLC controller 8 is connected on the magnetic strength probe 6 at winch 5 wheel rim places, the output D of PLC controller 8 is connected on the relay 4 on winch 5 patchboards, and the output of PLC controller 8 is connected on the display in drumman room.
People's car turnover tunnel is visited side 1 and is made up of common infrared mutual-tube and thermal infrared spool, and it is people or car that the Thermal Infra-Red pipe is used for distinguishing, and common infrared mutual-tube is used for the difference personnel and enters or withdraw from the tunnel.
When winch 5 travels in the tunnel, the magnetic strength probe 6 that is installed in winch drum wheel rim place is with measured winch stroke input controller 8, controller 8 begins to calculate mine car and has arrived where organize catcher 3 after receiving signal, and play-fall electromagnet 2 to this group catcher and send switching electricity order, thereby the control car lug lifts or lands under the adhesive of electromagnet 2.
When having the people to pass in and out in the tunnel, the people's car turnover tunnel detecting head 1 that is installed in the tunnel import and export begins the identification personnel and passes in and out signal, and with signal input controller 8, controller 8 begins counting automatically after receiving signal, and the result is offered display 7, and grasping at any time for drumman has people's situation in the tunnel, when the driver is having man-hour still to start winch, controller 8 sends signal and makes relay 4 automatic disconnections behind the time-delay certain hour, winch has a power failure and braking, and mine car is out of service.When in the tunnel nobody the time, controller 8 counting is zero, display 2 shows that personnel's situations are zero, drumman is known the unmanned winch that starts in the tunnel, controller 8 immediate instruction relays 4 auto-closings, mine car energising operation by display 7.
