Description
Technical field
The utility model relates to the coal engineering, is used to connect the gas pumping hose connection device of gas pumping flexible pipe in particularly a kind of gas pumping process.
Background technique
In the continuous progress that mine is produced, along with the coal seam of being exploited is more and more darker, it is not increasing by the gas pressure in the working seam yet, safe and efficient for guaranteeing that mine is produced, need a large amount of construction extraction boreholes, and, utilize the gas pumping flexible pipe to carry out the extraction of gas by the extraction passage that several extraction boreholes constituted.Because down-hole extraction borehole degree varies with a varied topography, run through that needed gas pumping hose length also has nothing in common with each other between the extraction borehole, therefore need the gas pumping flexible pipe is closed the hole extraction.In the prior art, close the hole extraction and generally adopt the gas pumping flexible pipe directly to use the socketing method of iron wire colligation, therefore gas leakage easily influenced the effect of closing the hole extraction because the socket place sealing is poor, restricted the efficient of closing the hole extraction.Further, some coal mine adopts the gas pumping flexible pipe that has flange plate to close the hole extraction down at present, the technical problem of having leaked gas easily though solved socket place sealing difference, but there is defect of high cost in the gas pumping flexible pipe that has flange plate, and since have the gas pumping hose length of flange plate limited and and do not fit into complex-terrain variation mine under.
The model utility content
The purpose of this utility model provides a kind of gas pumping hose connection device, close the high technological deficiency of gas pumping flexible pipe cost that tube socket place of the existing gas pumping of hole extraction seals difference and has flange plate to solve prior art, realize that gas pumping tube socket place seals purpose good and reduction gas pumping flexible pipe cost.
For achieving the above object, the utility model provides a kind of gas pumping hose connection device, wherein, comprising: ring-like reinforcing bar, and described ring-like reinforcing bar becomes spring-like, and the other end of an end of described ring-like reinforcing bar and described ring-like reinforcing bar is greater than 360 degree stacks; First nut is arranged on an end of described ring-like reinforcing bar; Second nut is arranged on the other end of described ring-like reinforcing bar; The 3rd nut is that axis and described first nut are symmetricly set on the described ring-like reinforcing bar with the diameter of ring-like reinforcing bar, and described the 3rd nut and the described first nut concentric; The 4th nut is that axis and described second nut are symmetricly set on the described ring-like reinforcing bar with the diameter of described ring-like reinforcing bar, and described the 4th nut and the described second nut concentric.
By above technological scheme as can be known, a kind of gas pumping hose connection device provided by the utility model, solved the high technological deficiency of gas pumping flexible pipe cost that prior art is closed the existing gas pumping of hole extraction tube socket place sealing difference and had flange plate, realized that gas pumping tube socket place seals purpose good and reduction gas pumping flexible pipe cost.
