Description

Technical Field

[0001] This utility model belongs to the field of gas pipeline fixing, specifically relating to a gas pipeline fixing bracket inside a well. Background Technology

[0002] In coal mining, natural gas development, and underground engineering operations, the gas extraction pipeline system serves as a core safety guarantee, and its structural stability directly affects the operational safety of the entire production system. Due to the complex environment of the shaft (vertical or inclined), gas pipelines need to withstand multiple complex loads over long periods. Therefore, fixed supports play a crucial role in the gas pipeline system.

[0003] Existing gas pipeline fixing supports generally adopt welded rigid supports or simple clamp structures. During the installation process, the fixing support first needs to be connected to the embedded parts in the well to ensure the stability of the fixing support. However, in actual operation, when we connect the fixing support to the gas pipeline, due to the errors in the well construction or gas pipeline construction, there is a small deviation between the gas pipeline and the fixing support. This deviation not only significantly increases the difficulty of installation, but misalignment exceeding 3mm will also cause local stress concentration in the pipeline.

[0004] Therefore, corresponding improvements should be made to address the shortcomings of existing fixed supports. Utility Model Content

[0005] In view of the fact that existing gas pipeline fixing supports generally adopt welded rigid supports or simple clamp structures, in actual operation, when we connect the fixing support to the gas pipeline, due to the error of well construction or gas pipeline construction, there is a small deviation between the gas pipeline and the fixing support, which increases the difficulty of installation and construction. This utility model provides a gas pipeline fixing support inside the well.

[0006] The solution adopted by this utility model to solve its technical problem is: a gas pipeline fixing bracket in a well shaft, including a U-shaped plate, a connector, a fixing sleeve, a U-shaped screw, and a pre-embedded rod for pre-embedding on the well shaft, wherein the U-shaped plate and the pre-embedded rod are detachably connected by a fixing component;

[0007] The fixing sleeve is set at the front end of the U-shaped plate, and a connector is fixedly installed between the fixing sleeve and the U-shaped plate;

[0008] The fixed sleeve has a strip-shaped hole, in which an adjusting arm is installed. The adjusting arm can slide along the inner cavity of the fixed sleeve, and there are two through holes on the adjusting arm.

[0009] The U-shaped screw is fitted onto the outside of the gas pipe. One end of the U-shaped screw protrudes through a strip hole and a through hole, while the other end protrudes through another through hole. Both ends of the U-shaped screw are threaded with fastening nuts.

[0010] Preferably, the connector includes a fixing nut and a high-strength screw. The fixing nut is welded and fixed inside the front opening of the U-shaped plate. One end of the high-strength screw is threadedly connected to the fixing nut, and the other end is fixedly connected to the fixing sleeve.

[0011] Preferably, the fastener is a bolt or a pin.

[0012] Preferably, the adjusting arm has two trapezoidal blocks welded and fixed on one side of the gas pipeline, and the two trapezoidal blocks are in contact with the outer surface of the gas pipeline.

[0013] Preferably, the fixing sleeve and the adjusting arm are made of square or rectangular tubes, and the U-shaped plate is made of channel steel.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model uses a threaded connection structure between a high-strength screw and a fixing nut to achieve the adjustment of the distance between the fixing sleeve and the U-shaped plate. The adjusting arm can slide laterally within the fixing sleeve. Through multi-directional adjustment, it can effectively adapt to the deviation between the gas pipeline and the fixed support, reduce the local stress concentration problem caused by the misalignment of the gas pipeline and the fixed support, and not only improve the safety and stability of the pipeline system, but also improve the installation efficiency.

[0016] 2. The fixed bracket designed in this utility model is connected by fasteners, high-strength screws, U-shaped screws and other components, which can be quickly disassembled or assembled. This not only makes the installation more flexible and convenient, but also allows for quick disassembly and replacement of specific components during later maintenance. Attached Figure Description

[0022] Example 1:

[0023] according to Figure 1 and Figure 2 As shown, it includes a U-shaped plate 1, a connector, a fixing sleeve 7, a U-shaped screw 8, and a pre-embedded rod 2 for pre-embedding on the well shaft. The U-shaped plate 1 and the pre-embedded rod 2 are detachably connected by a fixing member 3, which is a bolt or a pin, so that the U-shaped plate 1 and the pre-embedded rod 2 can be quickly assembled or disassembled.

[0026] The U-shaped screw 8 is fitted onto the outside of the gas pipeline. One end of the U-shaped screw 8 passes through a strip hole 71 and a through hole, and the other end passes through another through hole. Both ends of the U-shaped screw 8 are threaded with fastening nuts 10 to fix the gas pipeline and improve the safety and stability of the pipeline system.

Then, the U-shaped plate 1 is connected to the pre-embedded rod 2 through the fixing part 3. Then, the U-shaped screw 8 is pre-fitted on the outside of the gas pipeline and the adjusting arm 6 is pushed to slide in the fixing sleeve 7. Then, the two ends of the U-shaped screw 8 are respectively passed through the two through holes of the adjusting arm 6. Finally, the fastening nuts 10 on both sides are tightened alternately to fix the gas pipeline.
