Abstract
A hanging bridge pneumatic control disaster relief door is provided. The utility model comprises a hoisting door and a high pressure pneumatic device of controlling the hoisting switch; wherein one end of the hoisting door board is connected onto the bottom of the doorframe, while the other end is provided with a fixed hole connected with a cable wire; and one end of the cable wire is fixed in the fixed hole, while the other end is fixed on a cylinder bracket striding over the doorframe top to a guide pulley block; and the cylinder device is arranged on the cylinder bracket. The high pressure gas is adopted as the power source and the control signal of the disaster relief door, and the high pressure gas is sent to the underground mine from the ground, without influencing the supply of high pressure gas due to the disaster happening in the underground mine, thus ensuring the operating power and control signal of the disaster door and greatly improving the reliability of the disaster door; due to the power and control of the disaster door is not required the electriicty, thus the hidden danger brought by the unsafe electric is avoided. The utility model is best suitable for the disasters of underground mine fire hazard or fire damp explosion, opening or closing the harmful or poisonous gas to avoid flowing or scattering into the mining area and guiding the harmful gas into the ventilation system main airway.
Description
Technical field
The utility model relates to suspension bridge type pneumatic control disaster relief door, when being particularly useful for disasters such as breaking out of fire of mine down-hole or gas explosion, block toxic and harmful mobile and diffusion effectively by starting opening or closing of this pneumatic control disaster relief door, or toxic and harmful is imported the ventilation system main return airway to the exploiting field.
Background technology
When disasters such as breaking out of fire of mine down-hole or gas explosion, the casualties that fire or gas explosion directly cause is seldom, and a large amount of toxic and harmfuls that the main cause that causes the dead group of personnel group to hinder produces when to be disaster take place cause personnel's poisoning and death by suffocation to the intrusion in exploiting field with spread in the exploiting field in.If in the zone of possible breaking out of fire or gas explosion hidden danger, set up a calamity emergency rescue system in advance, just can stop or reduce personnel in the pit's secondary injures and deaths.The major function of this emergency rescue system is: in case disaster takes place, start emergency rescue system immediately, toxic and harmful is limited in regional area, prevent that it from continuing to spread and diffusion; Or toxic and harmful imported the ventilation system main return airway.
The control gate that is used for the mine gas explosion and the fire disaster relief at present mainly contains explosion proof door, labeled door and ventilation system inverted ventilation door.The effect of explosion proof door is when gas explosion takes place, to block the shock wave and the flame transmission of gas explosion with this.But, when magnitude of explosion is higher, explosion proof door is easy to be destroyed, do not have explosion-proof effect, for example on November 27th, 95, Heilungkiang Qitaihe branch company of dragon coal group blasts explosion proof door and the heavy damage of inverted ventilation facility in the east wind colliery, dead 134 people, the overwhelming majority is to suck toxic gas to be poisoned to death.The effect of labeled door is, when the mine breaking out of fire, by closing labeled door, burned flame and toxic and harmful intercepted in the labeled door inboard, avoids it to spread and spreads.But the labeled door that just present mine uses, the problem of two aspects of existence: (1) most of existing labeled door is not realized Long-distance Control, in case breaking out of fire can not be closed in time and be incured loss through delay the best opportunity of the disaster relief; Perhaps, spreading of fire make labeled door ineffective fully owing to causing personnel to close the door.(2) labeled door of indivedual mines has been realized Long-distance Control, what its control mode adopted is automatically controlled, and automatically controlled mode is owing to adopting the cable transmission remote control signal, when disaster takes place, if the destroyed or down-hole of cable has a power failure, all can cause the malfunctioning of Long-distance Control and lose due anti-fire action.The effect of ventilation system inverted ventilation door is that when in the exploiting field disaster taking place, these inverted ventilation doors of Long-distance Control open or close, and change distinguished and admirable mobile direction in the exploiting field.Because the inverted ventilation door only plays the effect that changes wind direction, thereby have the problem of three aspects: (1) can't be limited in toxic and harmful regional area and spread and spread unavoidably; (2) when in the exploiting field disaster taking place, owing to can't accurately grasp to the destruction situation of disaster place, disaster scale and ventilation equipment, thereby cause the policymaker to be difficult to decision and whether take the inverted ventilation measure, because the possibility of result of inverted ventilation is to have rescued some people and sacrificed another part people; (3) control mode of far controlling the inverted ventilation door is automatically controlled, and automatically controlled mode when disaster takes place, if cable is destroyed or the down-hole power failure, all can cause the malfunctioning of Long-distance Control owing to adopt the cable transmission remote control signal.
The utility model content
In view of the weak point that prior art exists, the purpose of this utility model provides a kind of simple in structure, and it is convenient to open, the remote controlled suspension bridge type pneumatic control disaster relief door that it opens or closes.
For achieving the above object, the utility model is made of the high pressure gas pneumatic means that plays overhang-door and control lifting door switch, door-plate one end that plays overhang-door is hinged on the doorframe bottom, the other end is provided with the fixing hole that links to each other with wire rope, wire rope one end is fixed in the fixing hole, and the other end strides across the doorframe top and is fixed on the cylinder support through the leading block group; Pneumatic means is located on the cylinder support.
Described leading block group is made of leading block that is located at the doorframe top and the leading block that is located on the cylinder support; Described pneumatic means comprises cylinder, is provided with piston push rod in the cylinder, and the cylinder two ends are provided with the high-pressure air pipe that feeds gases at high pressure, and the high-pressure air pipe pipeline is provided with Pneumatic valve.
The beneficial effects of the utility model are:
(1) adopts power source and the control signal of gases at high pressure as disaster relief door, gases at high pressure are transported to the down-hole by ground, can be owing to the supply that disaster influences gases at high pressure does not take place in the down-hole, thereby guaranteed the operation power and the control signal of disaster relief door, greatly improved the reliability of disaster relief door;
(2) adopt the control signal of gases at high pressure as disaster relief door, only need to lay one from ground (or shaft station) to the gases at high pressure signal pipe of disaster relief door, control the action of disaster relief door by being installed in switch on the gases at high pressure signal pipe, realize the Long-distance Control of disaster relief door;
(3) because the electric dangerous potential safety hazard of bringing has been avoided in the power of disaster relief door and not electricity consumptions of control.
(4) can guarantee that disaster relief system can run well when disaster takes place, Men Tiping crouches in the tunnel when being failure to actuate at ordinary times, and people, car can normally pass through, and do not influence ordinary production;
(5) Long-distance Control its open or close, the toxic and harmful that produces after the catastrophe can be enclosed in the confined space, or toxic and harmful is imported main return airway, that avoids toxic and harmful further spreads and spreads the secondary injures and deaths that cause the personnel in the pit.Have important practical significance and practical value to improving colliery disaster accident rescue and relief work present situation.
