Description
TECHNICAL FIELD
[0001] The utility model belongs to gas gas pumping technical field especially relates to a gas gas pumping pipeline device. BACKGROUND
[0002] In the process of coal mining, the gas in the mining underground needs to be pumped out, specifically, in the process of mining operation, once the gas in the coal seam exceeds the safe concentration, the risk of explosion is extremely easy to occur. Therefore, the pumping pipeline for pumping out gas is often used in the roadway. Specifically, the gas pipeline is laid along the trend of the roadway to avoid affecting the normal equipment and personnel flow.
[0003] In the actual application process, the gas pipeline can only be installed in an exposed manner, and the working environment in the mine is relatively complex. Large equipment often produces flying stones during operation, such as drilling holes in the roadway. The flying stones have a large kinetic energy, and once they hit the gas pipeline, the gas pipeline may be deformed, or the gas pipeline may be damaged if the sealing of the interface is not high, and the gas near the gas pipeline has a certain concentration, which may cause the flying stones to collide with the pipeline and produce sparks, thereby causing accidents.
[0004] In addition, unlike the traditional pipeline for pumping water, the diameter of the gas pipeline is often large in order to improve the pumping effect, thereby further increasing the probability of the gas pumping pipeline being hit by flying stones.
[0005] During the pumping of gas, especially the gas pipeline near the gas pumping end, the gas concentration in the environment near the pumping end is relatively high due to the high gas concentration in the coal seam. Therefore, if the gas pipeline is not protected to avoid damage to the gas pipeline by flying stones or roadway falling stones, the safety of the gas pumping operation cannot be guaranteed.

[0042] Example 1
[0043] like Figures 1-5 As shown, a gas extraction pipeline device includes an extraction pipeline 1 for extracting gas, and several anti-flying rock impact mechanisms are installed on the extraction pipeline 1. In actual operation, the anti-flying rock impact mechanisms are installed on the extraction pipeline 1, especially on pipelines laid near the operating area of large equipment, to increase the safety of the extraction pipeline 1.
[0044] Specifically, each anti-rock impact mechanism comprises a pair of clamp structures 4 arranged at intervals on the front and back sides, the clamp structures 4 are clamped on the exhaust pipeline 1, the clamp structure 4 comprises a pair of clamp bodies arranged in a hinged manner, specifically the same as the existing clamp structure 4, the clamp structure 4 comprises a first clamp body 41 and a second clamp body, the lower end of the first clamp body 41 is fixedly connected with a hinged boss 411, the lower end of the second clamp body is provided with a hinged notch, and the hinged boss 411 is hingedly connected in the hinged notch through a pin shaft.
[0045] Meanwhile, the upper end of the first clamp body 41 is integrally formed with a first protrusion 41, and the upper end of the second clamp body is integrally formed with a second protrusion; a fixed screw 412 is threadedly connected to the first protrusion, and a bayonet hole matched with the fixed screw is formed in the second protrusion, and the fixed screw 412 is clamped into the bayonet hole when the first clamp body 41 and the second clamp body are closed; a positioning nut 51 is threadedly connected to the fixed screw 412.
[0046] In this way, the clamp structure 4 is clamped on the pipeline. Meanwhile, in order to improve the clamping tightness between the pipeline, a rubber pad (in an arc shape) is fixed on the inner side wall of the first clamp body 41 and the second clamp body according to the existing mode.
[0047] Meanwhile, the first clamp body 41 is fixedly connected with a first fixed plate 42, and the second clamp body is fixedly connected with a second fixed plate; when the first clamp body 41 and the second clamp body are combined, the first fixed plate 42 and the second fixed plate are combined.
[0048] In order to realize protection of the exhaust pipeline 1, the above anti-rock impact mechanism further comprises a plurality of protection rods 5 slidably installed between the annular fixed plates.
[0049] Specifically, the protection rods 5 are distributed between the first fixed plate 42 and the second fixed plate, and are distributed in a ring shape.
[0050] When the flying rock hits the cage-shaped structure formed by the circumferential distribution of the protection rods 5, the protection of the exhaust pipeline 1 is realized under the protection of the protection rods 5.
[0051] During work, the clamp structures 4 on both sides are installed on the exhaust pipeline 1 in advance, and then the protection rods 5 are installed on the clamp structures 4 on both sides, specifically inserted between the first fixed plate 42 and the second fixed plate (specifically, the protection rods 5 are slidably connected with the first fixed plate 42 and the second fixed plate; the end portions of the protection rods 5 protrude correspondingly to the first fixed plate 42 and the second fixed plate). A cage-shaped protection structure is formed, and since the protection rods 5 are made of steel, the cage-shaped protection structure has high strength and is more resistant to the impact force of flying rocks, thereby realizing protection against large flying rocks.
[0052] Meanwhile, since multiple anti-flying stone impact mechanisms are used in conjunction to achieve the layout along the length of the pumping pipe 1, in order to fix adjacent anti-flying stone impact mechanisms in sequence, the ends of the above-mentioned protective rods 5 are threaded with connecting nuts, and adjacent anti-flying stone impact mechanisms are fixedly connected by connecting nuts.
[0053] The anti-flying stone impact mechanism is fixedly connected in sequence by nuts.
[0054] Example 2
[0055] like Figures 1-5 As shown, based on the structure of Embodiment 1, this embodiment further includes an elastic protective cylinder 3 sleeved on the outside of the protective rod 5. The elastic protective cylinder 3 is made of thickened plastic material, specifically formed by winding steel plates, thus possessing a certain degree of elasticity. Furthermore, because it is sleeved on the cage-like structure formed by the protective rod 5, the elastic protective cylinder 3 exhibits high stability under the support of the protective rod 5.
[0056] The purpose of installing the elastic protective sleeve 3 is to prevent small flying stones from penetrating through the gaps in the cage structure and hitting the pipe.
[0057] Specifically, the upper part of the elastic protective cylinder 3 is an open structure, and the upper two sides of the elastic protective cylinder 3 are closed and opened by several clamping structures 31.
[0058] Similar to the existing elastic snap-fit structure 31, the above-mentioned snap-fit structure 31 includes a snap-fit post 311 (metal material welded and fixed) fixedly connected to one side of the open structure, and a spring seat 312 is installed on the top of the snap-fit post 311. Specifically, a spring groove is provided on the top of the snap-fit post 311, and an inner spring (not shown in the figure) is fixedly connected to the bottom of the spring seat 312, with the inner spring fixedly connected to the bottom of the spring groove.
[0059] Correspondingly, a slot is provided on the other side of the above-mentioned open structure to cooperate with the locking post 311, and the slot is integrally formed with a through groove 313 for engaging the spring seat.
[0060] Simultaneously, pressing the spring retainer causes the spring retainer 312 to retract elastically into the spring groove, and the retaining post 311 engages with the groove. Under the elastic reset of the inner spring, the spring retainer 312 elastically engages with the through groove and protrudes from the opening 3131 of the through groove 313 (the curved top of the spring retainer 312 makes it easier to protrude from the opening 3131 of the through groove 313). During disassembly, pressing the spring retainer 312 retracts it into the through groove 313, and then prying it open.
[0061] During the insertion of the elastic protective cylinder 3, the elastic protective cylinder 3 is pre-bent (due to its elasticity) until the opening at the top gradually increases, and then it is inserted onto the outside of the protective rod 5. Each locking structure is then secured in the manner described above. This forms a sealed cylindrical protective structure that protects the outside of the protective rod 5, while the gaps between the protective rods 5 are completely covered under the cover of the cylindrical protective structure.
[0062] Example 3
[0063] like Figures 1-5 As shown, in this embodiment, based on the structure of embodiment 2, in order to further avoid damage to the protective mechanism by flying stones, especially flying stones with high kinetic energy, the outer side of the above-mentioned elastic protective cylinder 3 is wrapped with a rubber protective pad 2; under normal circumstances, the rubber protective pad 2 is in a flat state, but when wrapped, it is rolled into a cylinder and wrapped around the outer side of the elastic protective cylinder 3.
[0064] The specific method for fixing the free ends of the wound rubber protective pad 2 is as follows: Following the existing fixing method, the free ends of the rubber protective pad 2 are fixed using a hook and loop fastener. That is, adhesive fibers are fixed to one side of the free end of the rubber protective pad 2, and corresponding adhesive spikes are fixed at the hook and loop fastener positions (on the rubber protective pad 2) to achieve fixation after winding.
[0065] When a flying stone impacts the structure, the rubber protective pad 2 further cushions the impact force, thus further protecting the entire protective structure.
[0066] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
