Abstract
A pneumatic railroad switch which is convenient in utilization comprises a moving railroad switch, and a cylinder which is fixedly connected at the side of the moving railroad switch. The utility model has the advantages that the cylinder is adopted by the utility model to be considered as an executing mechanism, a mini-type air compressor is self-provided, and the cylinder is used for controlling the movement and the resetting of the moving railroad switch, thereby achieving time-saving and labor-saving effects, and convenient utilization.
Description
Technical field
The utility model relates to a kind of mine rail transport facility, relates in particular to a kind of pneumatic track switch.
Background technology
Along with the expansion day by day of mine scale, the improving constantly of mine output, the transportation safety demand improves constantly.Safety is placed above the other things always in current mine production, and this just means input, transformation and the management that will strengthen mine transportation safety facility; According to national official statistics, 1990-2002 whole nation industrial accident death toll is average annual to rise 6.28%; Coal in China output accounts for 35% of the whole world, and the death by accident number but accounts for 80%; Safe production equipment was invested low, was not complementary with the requirement that should have of GDP growth.Developed country's coal industry level of mechanization is near 100%, and China is below 70%.State-owned emphasis colliery quality standardization requires: inclined alley stopping device should meet " safety regulations in coal mine " regulation, and manual dexterity is reliable.Must use alley stopping device and buffer stop when using tube-train hoisting in " safety regulations in coal mine " the 370th requirement, gradient tunnel.The interlocking tumbler that generally use now in the colliery, pull rail transport facilities such as hanging beam, track switch and all have the irrational situation of design, especially control operation part, existing switch structure comprises: handle, and handle is connected with mobile track switch, during use, when mine car need pass through track switch, need manually move handle, mobile track switch is alignd with Fixed frog, after mine car passes through fully, move handle again, make track switch resetting.This kind track switch must be used manual operation, and is time-consuming during use, and effort is extremely inconvenient.
Summary of the invention
The purpose of this utility model provides a kind of pneumatic track switch easy to use.
For achieving the above object, the technical scheme that the utility model adopted is:
A kind of pneumatic track switch, comprising: mobile track switch, its characteristics are: the side of mobile track switch is fixedly connected with cylinder.
According to above-mentioned pneumatic track switch, its characteristics are: be fixedly connected with an air inlet pipe on the above-mentioned cylinder, an end of an air inlet pipe is connected with hand change over valve.
According to above-mentioned pneumatic track switch, its characteristics are: above-mentioned hand change over valve is the 3-position 4-way hand change over valve.
According to above-mentioned pneumatic track switch, its characteristics are: be connected with air inlet pipe on the above-mentioned hand change over valve, an end of air inlet pipe is connected with source of the gas and handles the bigeminy part.
According to above-mentioned pneumatic track switch, its characteristics are: above-mentioned source of the gas is handled on the bigeminy part and is connected with main air inlet pipe, and an end of main air inlet pipe is connected with shutoff valve.
The utility model has the advantages that: adopt cylinder to make actuating unit in the utility model, itself has mini air compressor; Control moving of mobile track switch and reset with cylinder, can save time, laborsaving, the convenient use.
Description of drawings
Fig. 1 is an actuating unit structural representation in the utility model.
Fig. 2 is a pneumatic control system scheme drawing in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:
A kind of pneumatic track switch, as shown in Figure 1, comprising: common mobile track switch 2 under the mine, the side of mobile track switch 2 is fixedly connected with cylinder 1.In the present embodiment, the control of the air pressure of cylinder is to adopt following scheme to realize, as shown in Figure 2, in the present embodiment, is fixedly connected with an air inlet pipe 3 on the cylinder 1, and an end of an air inlet pipe 3 is connected with hand change over valve common under the mine 4; In the present embodiment, hand change over valve 4 is a 3-position 4-way hand change over valve common under the mine; In the present embodiment, be connected with air inlet pipe 5 on the hand change over valve 4, an end of air inlet pipe 5 is connected with source of the gas common under the mine and handles bigeminy part 6; In the present embodiment, source of the gas is handled on the bigeminy part 6 and is connected with main air inlet pipe 7, and an end of main air inlet pipe 7 is connected with shutoff valve 8.
The wind regime that the utility model adopts the down-hole generally to use, by hand change over valve, direct drive actuating unit cylinder makes mobile track switch move or reset.The utility model uses down-hole liquid valve commonly used, and pressure duct is reliability and durability, safeguards simply there are not problems such as explosion-proof simultaneously; Propulsion source in the utility model is a source of the gas, and is inexhaustible from atmosphere, free from environmental pollution, safe in utilization.
