Abstract
This patent relates to a kind of climb and fall tunnel lattice door recloser, for drive security protection.The technical solution adopted in the utility model is: a kind of climb and fall tunnel lattice door recloser, comprise lattice door, pneumatic cylinder, winch run signal comprehensive guarantor circuit, it is characterized in that, the hinged access place being fixed on climb and fall tunnel of described lattice door, lattice door is connected to pneumatic cylinder motion bar and can rotates to block pedestrian side, upper and lower tunnel around hinged bearing, described pneumatic cylinder pipeline connects air pressure system, described pipeline is also provided with the work of solenoid control source of the gas pneumatic cylinder, and described electromagnetic valve circuit signal is connected to winch run signal and combines in guarantor's circuit.The utility model has the advantage of, when winch runs, in advance sidewalk is closed according to winch run signal, confirm synchronously to carry out with potential job safety, eradicate the potential safety hazard of driving pedestrian from source, decreased shipping accident rate, ensure that safe handling.
Description
Technical field
This patent relates to a kind of climb and fall tunnel lattice door recloser, for drive security protection.
Background technology
When winch of going down the hill in exploiting field runs, forbid pedestrian, the weak personnel of some awareness of safety, when hook personnel are not found, violating the regulationsly to pass through, bury potential safety hazard.Strict implement " pedestrian does not drive a vehicle, drive a vehicle not pedestrian, not operation ", how regulation being become interlock automatic control, is the difficult problem that management transported safely by puffer.
Summary of the invention
The purpose of this utility model is to provide a kind of climb and fall tunnel lattice door recloser.
For achieving the above object, the technical solution adopted in the utility model is: a kind of climb and fall tunnel lattice door recloser, comprise lattice door, pneumatic cylinder, winch run signal is combined and is protected circuit, it is characterized in that, the hinged access place being fixed on climb and fall tunnel of described lattice door, lattice door is connected to pneumatic cylinder motion bar and can rotates to block pedestrian side, upper and lower tunnel around hinged bearing, described pneumatic cylinder pipeline connects air pressure system, described pipeline is also provided with the switch of solenoid control blast and the work of pneumatic cylinder, described electromagnetic valve circuit signal is connected to winch run signal and combines in guarantor's circuit.
The utility model has the advantage of, when winch runs, in advance sidewalk is closed according to winch run signal, confirm synchronously to carry out with potential job safety, eradicate the potential safety hazard of driving pedestrian from source, decreased shipping accident rate, ensure that safe handling.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
In accompanying drawing: 1, lattice door; 2, pneumatic cylinder; 3, air pressure system; 4, electromagnetic valve; 5, winch run signal is combined and is protected circuit.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The utility model as shown in Figure 1,
A kind of climb and fall tunnel lattice door recloser, comprise lattice door 1, pneumatic cylinder 2, winch run signal comprehensive guarantor circuit 5, it is characterized in that, the hinged access place being fixed on climb and fall tunnel of described lattice door 2, lattice door 2 is connected to pneumatic cylinder 2 motion bar and can rotates to block pedestrian side, upper and lower tunnel around hinged bearing, described pneumatic cylinder 2 pipeline connects air pressure system 3, described pipeline is also provided with electromagnetic valve 4 and controls the switch of blast and the work of pneumatic cylinder, and described electromagnetic valve 4 circuit signal is connected to winch run signal and combines in guarantor's circuit 5.
At upper and lower mountain, exploiting field, down-hole pavement side fixed installation lattice door, adopt electromagnetic valve to coordinate pneumatic cylinder, connect 127v signal power source and air pressure system, electromagnetic valve with on winch signal of going down the hill be connected by controller, winch run signal combines guarantor's power supply.According to winch run signal, solenoid control pneumatic cylinder, promote lattice door action, winch run signal lattice door is closed automatically, and winch stop signal lattice door is opened automatically, reaches that 2 acoustic signals hook up, 3 acoustic signals pine cars, and sidewalk lattice door is closed automatically; During 1 sound fixed point, lattice door is opened automatically.
Lattice door indicates " driving forbid pedestrian " caution slogan.
This patent achieves the automation that lattice door opens and closes; Effectively eradicate the potential safety hazard of driving pedestrian by onsite application, ensure that safe handling.
Have received good effect by installing and using, when winch runs, in advance sidewalk being closed, confirm synchronously to carry out with potential job safety, eradicated the potential safety hazard of driving pedestrian from source, decreased shipping accident rate, ensure that safe handling, annual safe fund drops into 4.5 ten thousand yuan less.
