Abstract
The utility model discloses underground coal mine inclined gallery insurance shelves suitable for reading and winch blocking device, including insurance pneumatic operation case, insurance shelves operation valve, air-operated solenoid valve, insurance gear air cylinder, insurance shelves；Insure shelves operation valve and air-operated solenoid valve is set in insurance pneumatic operation case, insurance shelves operation valve connection insurance gear air cylinder, insurance gear air cylinder connection insurance shelves, insurance shelves operation valve connection air-operated solenoid valve.The beneficial effects of the utility model：When winch is run, after air-operated solenoid valve is powered, insurance shelves can be just opened；When winch stops, because dead electricity is closed, insurance shelves operation valve loses source of the gas to work air-operated solenoid valve, and shelves are insured when winch stops to work, and are realized winch and are insured the locking of shelves, improve the security of coal mine sloping lane work.
Description
Technical field
It the utility model is related to the safety device of underground coal mine inclined gallery, more particularly to the insurance suitable for reading of underground coal mine inclined gallery
Shelves and winch blocking device.
Background technology
Electromechanical Transportation in Coal Mine is the important component of shaft production link, and it has run through each production link of mine,
Battle line is grown, and involves a wide range of knowledge, and special work post is more, technical strong.Shown according to the investigation and analysis of national colliery major accident, electromechanical thing
Therefore the 4th is occupied in various accidents, shipping accident accounts for the 20%~30% of total accident number.Coal production shipping accident is mainly concentrated
In main lane, three parts are transported in transport, Inclined Lane Lifting transport and digging, and wherein inclined gallery are the multiple areas of shipping accident, coal mine sloping lane
Transport is an important step of coal production, is responsible for coal, cash, the transport task of various types of materials.The safety fortune of oblique lane transport
Row is to ensure the precondition that coal production is smoothed out.According to incompletely statistics, national Coal Transportation death tolls account for entirely
More than the 20% of portion's death tolls.Oblique lane transport accident number accounts for 48% or so of Coal Transportation accident, and death toll accounts for
61% or so of Coal Transportation.As can be seen here, importance of the oblique lane transport for Safety of Coal Mine Production.
Often occur that inclined gallery insurance shelves suitable for reading are opened and caused or not charged in advance during the oblique lane transport of underground
The phenomenon of car is sent, causes magnifying slip accident.
Utility model content
Technical problem to be solved in the utility model is the provision of safe underground coal mine inclined gallery insurance suitable for reading
Shelves and winch blocking device.
The utility model is that solve above-mentioned technical problem by the following technical programs：It is pneumatic that the utility model includes insurance
Control box, insurance shelves operation valve, air-operated solenoid valve, insurance gear air cylinder, insurance shelves；Insure shelves operation valve and air-operated solenoid valve is set
Insure in pneumatic operation case, insurance shelves operation valve connection insurance gear air cylinder, insurance gear air cylinder connection insurance shelves, insure shelves operation valve
Connect air-operated solenoid valve.
Preferably, the air-operated solenoid valve is additionally attached on winch running indicator working line.
Preferably, the insurance pneumatic operation case is provided with admission line, and wind regime is sent into air-operated solenoid valve by admission line.
Preferably, the wind regime is underground pressure air source of the gas.
Preferably, insurance shelves operation valve connects insurance gear air cylinder air inlet and gas outlet respectively.
Preferably, the insurance gear air cylinder piston connection insurance shelves.
Preferably, the insurance shelves are arranged on winch.
The utility model has advantages below compared with prior art：The utility model realizes that winch is run when winch starts
Lamp loop is connected, and air-operated solenoid valve, which is powered, opens air valve, and insurance shelves operation valve connects source of the gas, now operation insurance shelves operation valve hand
Handle can just open insurance shelves；When winch stops, for air-operated solenoid valve because dead electricity is closed, insurance shelves operation valve loses source of the gas can not
Work, when winch stops, insurance shelves can not work, and realize winch and insure the locking of shelves, improve coal mine sloping lane work
Security.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model underground coal mine inclined gallery insurance shelves suitable for reading and winch blocking device.
Insure pneumatic operation case 1 and insure the insurance insurance shelves 5 winch fortune of gear air cylinder 4 of air-operated solenoid valve 3 of shelves operation valve 2
The wind regime 7 of portable lighter 6
Embodiment
Embodiment of the present utility model is elaborated below, the present embodiment using technical solutions of the utility model before
Put and implemented, give detailed embodiment and specific operating process, but the scope of protection of the utility model is unlimited
In following embodiments.
As shown in figure 1, the present embodiment insurance pneumatic operation case 1, insurance shelves operation valve 2, air-operated solenoid valve 3, insurance shelves gas
Cylinder 4, insurance shelves 5；Insure shelves operation valve 2 and air-operated solenoid valve 3 is set in insurance pneumatic operation case 1, insurance shelves operation valve 2 connects
Insure gear air cylinder 4, the insurance connection insurance shelves 5 of gear air cylinder 4, insurance shelves operation valve 2 connects air-operated solenoid valve 3.
The air-operated solenoid valve 3 is additionally attached on the working line of winch running indicator 6.The insurance pneumatic operation case 1 is provided with
Wind regime 7 is sent into air-operated solenoid valve 3 by admission line, admission line.The wind regime 7 is underground pressure air source of the gas.Insure shelves operation valve 2
The connection insurance air inlet of gear air cylinder 4 and gas outlet respectively.The insurance gear air cylinder 4 piston connection insurance shelves 5.The insurance shelves 5
It is arranged on winch.
Utility model works process is as follows,
One air-operated solenoid valve 3, the electricity of air-operated solenoid valve 3 are installed in the air inlet side of insurance 1 case operation valve of shelves pneumatic operation
Source is connected on the circuit of winch running indicator 6, and when winch starts, the loop of winch running indicator 6 is connected, and air-operated solenoid valve 3, which is powered, to be opened
Air valve, insurance shelves operation valve 2 are connected source of the gas and can worked, and insurance shelves gas can be manipulated by now pulling the handle of insurance shelves operation valve 2
Cylinder 4 opens insurance shelves 5.When winch stops, because dead electricity is closed, insurance shelves operation valve 2 loses source of the gas and is unable to work air-operated solenoid valve 3
Make, so as to realize that shelves 5 are insured when winch stops to work, and realize winch with insuring the locking of shelves.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
