Technical Field
The utility model relates to the technical field of mine gas extraction, in particular to a gas extraction pipe positioner.
Background
Mine gas is a generic term for various harmful gases mainly including methane which are flushed from coal and rock in the production process of coal mines, and is a main natural factor which seriously threatens the safety production of the coal mines. Casualties and property loss caused by gas disasters are huge, so that prevention of the gas disasters has important significance for the health and sustainable development of the coal industry. At present, gas extraction is an important means for controlling gas in mine operation, and in the gas extraction process, the tight sealing of a drilling hole is required to be ensured, and the gas extraction device has a longer sealing length so as to ensure the gas extraction effect. The data show that poor sealing effect caused by the fact that the axial position of the gas extraction pipe placed in the gas extraction drilling hole deviates from the center of the gas extraction drilling hole excessively is one of main reasons for the fact that the sealing effect is not ideal.
The utility model patent with the application number of 202120539835X discloses a gas extraction pipe positioning mechanism, which comprises a sleeve base, a positioning support rod and a support tension spring, and can effectively solve the problem that a gas extraction pipe placed in a gas extraction drilling hole deviates excessively from the center of the gas extraction drilling hole. Because positioning mechanism installs on taking out the production pipe, when sealing the drilling, positioning mechanism also is sealed in the drilling, consequently belongs to the consumable that can not reutilization, among the above-mentioned technical scheme, positioning mechanism's structure is complicated, and the process is many during production, and the cost is high, and then has increased the gas and taken out the cost.
Disclosure of Invention
The utility model aims to overcome the existing defects, and provides the gas extraction pipe positioner which is simple in structure, easy to produce and low in cost, and the problems in the background technology can be effectively solved.
In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a gas extraction pipe locator, is including installing the main part in two extraction pipe junction, the main part includes the supporting legs that collar and side slope set up, and the connected mode of two extraction pipes has two kinds, is the link socket joint respectively and inserts two extraction pipe ends through the connecting pipe and connect, in two kinds of connected modes, the collar of main part overlaps respectively on link and connecting pipe, and the tip of two extraction pipes carries out the axial spacing to the main part.
As a preferable technical scheme of the utility model, the mounting ring and the supporting legs are integrally injection molded by PE materials.
As a preferable technical scheme of the utility model, the number of the supporting legs is not less than three and the supporting legs are arranged in an annular array with equal angles around the central axis of the mounting ring.
As a preferable technical scheme of the utility model, after the two extraction pipes are connected through the connecting end socket joint or the connecting pipe, the connecting parts are fixed through the adhesive.
Compared with the prior art, the utility model has the beneficial effects that: the gas extraction pipe positioner is arranged on the extraction pipe, so that the extraction pipe can be arranged at the central position of a drilling hole, the sealing performance of the subsequent hole sealing of the drilling hole by grouting is improved, the positioner is simple in structure, few in required materials, low in production cost and high in production speed, and the gas extraction cost can be obviously reduced when the gas extraction pipe positioner is used as a disposable consumable in a large amount.

FIG. 1 is a schematic diagram of the structure of the present utility model;
FIG. 2 is a schematic view of a first use state of the present utility model;
fig. 3 is a schematic view of a second use state of the present utility model.
In the figure: the device comprises a main body 1, a mounting ring 11, supporting feet 12, a connecting pipe 2, a pumping pipe 3, a pumping drilling hole 4 and a connecting end 5.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-3, the present utility model provides a technical solution: the utility model provides a gas extraction pipe locator, including installing the main part 1 in the junction of two extraction pipes 3, main part 1 includes collar 11 and supporting legs 12 that side slope set up, collar 11 and supporting legs 12 are by PE material integrative injection moulding, therefore production speed is fast, material cost is low, and supporting legs 12 elasticity is good, the quantity of supporting legs 12 is not less than three and around the axis equiangle annular array of collar 11, the connected mode of two extraction pipes 3 has two, be link 5 socket joint respectively and insert two extraction pipe 3 tip through connecting pipe 2 and connect, two extraction pipes 3 are connected the back through link 5 socket joint or connecting pipe 2, the junction is all fixed through the viscose, among the two connected modes, collar 11 of main part 1 overlaps respectively on link 5 and connecting pipe 2, the tip of two extraction pipes 3 carries out the axial spacing to main part 1.
When in use: before the extraction pipe 3 stretches into the extraction drilling 4, a plurality of extraction pipes 3 are needed to be spliced to prolong the length of the extraction pipes 3 to reach the required extraction length, no matter the connection ends 5 of the extraction pipes 3 are connected in a socket connection mode or the connection is carried out by means of additional connecting pipes 2 during splicing, the inner diameter of the mounting ring 11 of the main body 1 is slightly larger than the inner diameter of the extraction pipes 3, the mounting ring 11 can be easily sleeved on the connection ends 5 or the connecting pipes 2, after the main body 1 is sleeved, both sides of the mounting ring 11 are tightly propped by the end parts of the two extraction pipes 3, then glue is used for fixing the joint of the two extraction pipes 3, namely the main body 1 is fixed, after the extraction pipe 3 sleeved with the main body 1 stretches into the extraction drilling 4, the support legs 12 which are annularly arranged are elastically contacted with the inner walls of the extraction drilling 4, the deep penetration of the extraction pipes 3 are not too much hindered, the supporting effect is also achieved, the fact that the extraction pipes 3 can be arranged at the central position of the extraction drilling 4 is ensured, and the sealing performance of the inside of the extraction drilling 4 after grouting is improved.
