The automatic closure device is characterized in that the car arrester capable of lifting automatically is arranged on a running track of the lifting container in a slope mine, an electro-magnetic inductor is mounted above the car arrester, and a place relay is added in the electrical control system. The utility model realizes the connection of a single circuit of the car arrester and the electrical control system of a winch, improves the safety system of the winch passing through the car arrester on the original foundation, effectively prevents the generation of losing control, ensures the safe production, and further improves the comprehensive benefit of an enterprise.
Description
Technical field
The utility model relates to the inclined shaft hoisting system, relates to a kind of inclined shaft hoisting system stop device forced locking device specifically.
Background technology
Along with the needs of production development and the progress of science, former winch elevator system control path adopts relay-contactor control system along with the developing rapidly of Eltec, changes the automation and the computer control of whole process of production into.The new beautiful colliery hoister control system of Dengfeng, Henan is the PLC programmable controller; this system is controlled by two FX2N series of PLC; adopt silicon control excision rheostatic speed regulation mode; have upper monitoring digital displaying meter and digital depth indicator; every fender guard is complete; and sensitive reliable, and satisfy " safety regulations in coal mine " requirement to protecting equipments for elevating conveyor.
According to regulation in " safety regulations in coal mine ", the auxiliary facility of inclined shaft must be installed sloping three retainings.This ore deposit is gone into 15 meters of well head at subincline Obstruct apparatus has been installed as requested, and this stop device is installed the hydraulic lifting take-off and landing device, and installing is sought to wheel, promoted the steel rope that rises and falls, and interlocks with winding engine indicator.Vehicle is during apart from well head 50m, and automatic deceleration is 2m/s, and during apart from well head 30m, stop device begins action and rises, and falls after rise automatically in the vehicle back that puts in place, realizes automatic guidance.The winch operative employee look on the depth indicator by sight start, hold up traffic, traffic pilot lamp determines stop device action situation.
By using, when (as: disconnected rope, stop device misoperation etc.) situation having occurred after stop device rises, falling suddenly again, operating personal can not in time be found, even find the back because inertia can not stop immediately, add that lifting container run location and stop device are very near, very easily cause vehicle and stop device collision accident.
Summary of the invention
The utility model is just at the weak point that exists in above-mentioned original technology, and the inclined shaft hoisting system stop device forced locking device of a kind of high safety factor that provides.
The purpose of this utility model can realize by following technique measures: this inclined shaft hoisting system stop device forced locking device, comprise that gig, gig hauling rope by electric control system controls are connected with lifting container by pulley frame, wherein: the orbit of the lifting container in the inclined shaft is provided with the stop device that can rise automatically, and an electromagnetic induction switch is installed above stop device, in electric-control system, increase by the relay that puts in place, by electromagnetic inductor and the signal transmission of the relay that puts in place and then closing and opening of control stop device.
In the utility model, stop device is controlled by hydraulic efficiency gear.
Operation practical approach of the present utility model is as follows:
The inclined shaft hoisting container is during apart from well head 50m, it is 5 seconds to rising to bit time that stop device begins action, the back electromagnetic induction switch that puts in place is subjected to induction to send signal and reaches the relay that puts in place, traffic pilot lamp is bright on operator's station, the depth indicator, and transmits signal to the PLC safety return circuit, under the situation that this condition satisfies, lifting container can pass through safely, prevent that derailing accident from taking place, otherwise gig cuts off the power supply automatically, out of service.
The single circuit of the utility model realization stop device is connected with the winch electric-control system, compares with original base and has improved the safety system of winch by stop device, makes the safety benefit of enterprise be able to further raising.
Description of drawings
Accompanying drawing is the utility model connection diagram.
Among the figure: the 1st, lifting container, the 2nd, electromagnetic inductor, the 3rd, stop device, the 4th, well head, the 5th, pulley frame, the 6th, gig, the 7th, the relay that puts in place, the 8th, depth indicator, the 9th, track.
The specific embodiment
The utility model is described further below in conjunction with accompanying drawing: this inclined shaft hoisting system stop device forced locking device, comprise gig 6 by electric control system controls, the gig hauling rope is connected with lifting container 1 by pulley frame 5, wherein: the orbit 9 of the lifting container in the inclined shaft is provided with the stop device 3 that can rise automatically, stop device is controlled by hydraulic efficiency gear, one electromagnetic inductor 2 is installed above stop device, in electric-control system, increase by the relay 7 that puts in place, by electromagnetic inductor 2 and the signal transmission of the relay 7 that puts in place and then closing and opening of control stop device 3.
Its working process is as follows:
As shown in the figure, in the normal lifting process, when lifting container 1 when stop device (3) moves below the 50m, stop device 3 is in normally off (normally off is in blocking state exactly), when lifting container 1 is promoted to apart from well head 50m, electromagnetic inductor 2 receives induced signal and sends signal relay 7 actions that put in place to the hoist control system, the hydraulic efficiency gear power supply of stop device 3 under the conducting well head, the hydraulic actuating cylinder release, traction wheel rotates, stop device 3 begins to mention, and lifting container 1 safety is passed through.When the pointed fixed position on the winding engine indicator 8, the relay 7 that must put in place in the hoist control system disconnects, signal hydraulic efficiency gear to the well head is sent in the action of another relay (M200) in the electric-control system, and its power turn-on traction wheel begins action rotation stop device 3 and comes back to normally off.
When lifting container 1 is transferred in the down-hole, depth indicator 8 begins to descend with gig 6, the relay 7 (M129) that puts in place when the pointed fixed position in the PLC loop receives signal, current lamp (M811) on depth indicator 8 and the operator's station is bright simultaneously, and the electromagnetic inductor on the stop device under the well head 32 sends signal to hydraulic efficiency gear, power turn-on, hydraulic actuating cylinder begins the release traction wheel and rotates, stop device 3 begins to rise, container 1 to be hoisted is by behind the 50m, electromagnetic inductor 2 signal that loses induction disconnects, another relay (M200) conducting in the hoist control system, stop device 3 hydraulic efficiency gear energising traction wheel is rotated, and stop device 3 is got back to normally off again.
