Description

Technical Field

[0001] This application relates to the field of mining pipeline support structure technology, and in particular to a pipeline support with adjustable cross-section. Background Technology

[0002] With the rapid development of the national economy, the management of hot work operations in underground mining projects in the non-metallic mining industry is becoming increasingly stringent, leading to a higher risk of fire caused by hot work underground. Currently, due to the uneven rock formations on both sides of various underground mine roadways, it is difficult to fix pipe supports and level them when installing ventilation and water pipes. Traditional supports are mostly fixed by welding angle steel or bolting, which are bulky, inconvenient to install and disassemble, and difficult to adapt to the fixing requirements of different pipe specifications. They also lack effective anti-vibration measures, which can easily lead to pipe loosening and falling off. Moreover, traditional methods require hot work to be carried out underground.

[0003] Furthermore, traditional support installation is complex, requiring tools for welding or bolting, which consumes significant manpower and time. Existing supports are ill-suited to the needs of laying pipes of varying diameters and quantities, exhibiting poor versatility. Insufficient load-bearing capacity and inadequate shock absorption measures can easily lead to pipe detachment, threatening the safety of personnel underground. The high frequency of hot work during pipe installation makes fire safety management difficult. However, using 18# threaded steel bars fixed to the sides of the tunnel and 15# channel steel as the bottom support for the pipes, adjusting the diagonal bracing at the bottom of the channel steel by twisting the screws and nuts allows the supports to be adjusted according to the actual installation conditions.

[0004] Therefore, there is an urgent need to provide a technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0005] The purpose of this application is to provide a pipe support with an adjustable cross-section, which overcomes the problems of uneven installation and fixing, inability to adjust the height of existing pipe supports, and high frequency of underground hot work operations.

[0006] To achieve the above objectives, this application provides the following technical solution: An adjustable cross-section pipe support includes a 16# channel steel. A first 18# threaded steel bar and a second 18# threaded steel bar are respectively provided on one side of the 16# channel steel. A 16# long threaded rod is provided below the 16# channel steel. An M24 welding nut is provided on the 16# long threaded rod. A first 16# steel bar and a second 16# steel bar are respectively provided on both sides of the M24 welding nut. A 12# steel plate is provided between the first 16# steel bar and the second 16# steel bar, away from the M24 welding nut. A third 18# threaded steel bar is provided on the 12# steel plate. A pipe bracket is provided on the 16# channel steel.

[0007] Preferably, the pipe bracket is horizontally arranged, and the top of the pipe bracket is provided with an arc-shaped pipe bracket, and the central angle of the arc-shaped pipe bracket is less than or equal to 180°.

[0008] Preferably, the plane of symmetry of the central angle of the arc-shaped pipe bracket is perpendicular to the length direction of the 16# channel steel.

[0009] Preferably, the 16# channel steel is arranged horizontally along its length, and the length directions of the first 18# threaded steel bar and the second 18# threaded steel bar are parallel to the length direction of the 16# channel steel.

[0010] Preferably, half the length of the first and second 18# threaded steel bars is located outside the 16# channel steel.

[0011] Preferably, the angle between the 16# long threaded screw and the 16# channel steel along its length is less than or equal to 90°.

[0012] Preferably, the length directions of the 16# long threaded rod, the first 16# steel bar, the second 16# steel bar, and the third 18# threaded steel bar are parallel to each other.

[0013] More preferably, the first #16 steel bar and the second #16 steel bar are symmetrically arranged about the #16 long threaded screw.

[0014] Beneficial effects: This invention overcomes the problems of uneven installation and fixing, inability to adjust the height of pipe supports, and high frequency of downhole hot work in the prior art. It provides a method for adjusting the support height with screws and nuts, and pre-supporting the downhole installation from the surface. The modular design enables rapid installation and disassembly, improving installation efficiency.

[0015] This invention features a rubber pad on the inner surface of the pipe bracket, employing elastic shock-absorbing rubber pads and an anti-fall-off structural design (arc-shaped pipe bracket). This effectively absorbs pipe vibration and prevents the pipe from loosening and falling off. This method offers high work efficiency, is particularly suitable for working environments with significant fire hazards, and can be applied industrially. Attached Figure Description
