[0002] There are a large number of pipeline systems in large coal mines, which are used to transport water, gas, chemicals, etc. In order to ensure the safe and stable operation of the pipeline system, pipeline supports and hangers are required to support and fix the pipelines.

[0003] A support bracket is a device used to support and fix pipelines. It is used to support pipelines and ensure that the pipelines maintain a stable position and height during installation and use. It can absorb vibrations caused by fluid flow or other external factors and protect pipelines and connectors from damage. During the installation of the pipeline system, pipeline supports and hangers can be used to support pipelines to facilitate construction workers to weld, connect and install.

DETAILED DESCRIPTION

[0028] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0029] Implementation example:

[0030] like Figure 1As shown, an earthquake-resistant support and hanger for a large coal mine includes a mounting structure 2000 fixed on the top of a coal mine passage, a frame structure 1000 for placing and laying a pipeline 4000, and a connecting structure 3000 connecting the mounting structure 2000 and the frame structure 1000.

[0031] like Figure 4 As shown, the mounting structure 2000 is a mounting frame 2100 of a hollow box structure, which is fixed to the top of the mine passage by bolts, and a mounting groove 2110 is provided at the lower end of the mounting frame 2100 for the connection structure 3000 to pass through, and mounting frame slide rails 2120 are symmetrically provided on both sides of the mounting groove 2110, and a limit block 2130 is provided at one end of the mounting frame slide rail 2120 away from the mounting groove.

[0032] like Figure 3 As shown, the connecting rod 3100 in the connecting structure 3000 includes a connecting lower rod 3110 and a connecting upper rod 3120. The hollow interior of the connecting lower rod 3110 is provided with a connecting lower groove 3111. The lower end of the connecting upper rod 3120 passes through the upper end surface of the connecting lower rod 3110 and enters the connecting lower groove 3111. An elastic component is provided between the lower end surface of the connecting upper rod 3120 and the upper end surface of the connecting lower rod 3110. In this embodiment, the elastic component is a spring. The spring prevents the connecting upper rod 3120 from moving downward and the connecting lower rod 3110 from moving upward, thereby realizing the buffering of the support bracket of the utility model in the vertical direction.

[0033] like Figure 5 As shown, a connecting block 3200 is provided at the upper end of the upper rod 3120, and a connecting groove 3210 is provided at the lower end of the connecting block 3200 corresponding to the mounting frame slide rail 2120. The connecting groove 3210 matches the size of the mounting frame slide rail 2120 and can move on the mounting frame slide rail 2120. After passing through the mounting groove 2110, the connecting block 3200 is inserted into the mounting frame slide rail 2120. Springs are provided between the two ends of the connecting block 3200 and the limit blocks 2130. The springs prevent the connecting block 3200 from moving forward and backward on the mounting frame slide rail 2120, thereby realizing the buffering of the support and hanger bracket of the utility model in the forward and backward directions.

[0034] The lower connecting rod 3110 and the frame connecting part 1200 are adjustably connected and are fixed with bolts through corresponding through holes provided through the outer surfaces of the two. The installation height of the support and hanger of the utility model can be adjusted to adapt to the laying of pipelines at different heights.

[0035] like Figure 2As shown, the frame structure 1000 includes a frame support part 1100 for supporting the pipeline 4000, and frame connection parts 1200 extending upward at both ends of the frame support part 1100; the frame support part 1100 is provided with a concave clamping groove 1110 perpendicular to the pipeline laying direction, and the lower end of the clamping structure 1300 is arranged in the clamping groove 1110 and can slide in the clamping groove 1110. The clamping structure 1300 includes a plurality of clamping blocks 1310 arranged in parallel, and the clamping blocks 1310 include a clamping lower block 1312 moving in the clamping groove 1110, and the upper end surface of the clamping lower block 1312 is a clamping upper block 1311 protruding upward. The pipe 4000 is placed between adjacent clamping upper blocks 1311 and can be locked by a clamping belt 1330 arranged on the upper end surface of the adjacent clamping upper blocks 1311. The clamping belt 1330 is a belt structure with certain strength and flexibility, or a clamp with adjustable length, which clamps and closes the upper opening between the adjacent clamping blocks 1310.

[0036] The clamping blocks 1310 at both ends of the clamping structure 1300 are adjustment clamping blocks 1320, and the frame connecting parts 1200 on both sides are symmetrically provided with adjustment rods 1400. The adjustment rods 1400 pass through the frame connecting parts 1200 from the side and extend to the adjustment clamping blocks 1320. The adjustment rods 1400 are threadedly connected to the frame support part 1100. The adjustment rods 1400 are rotated to make them abut against the adjustment clamping blocks 1320. The spacing between the clamping blocks 1310 is adjusted by the degree of screwing in of the adjustment rods 1400 to adapt to pipes 4000 of different specifications and the degree of clamping. At the same time, a spring is provided between the adjustment clamping block 1320 and the frame connecting part 1200 in the clamping groove 1110. The spring prevents the clamping structure 1300 from moving left and right in the clamping groove 1110, thereby realizing the buffering of the support bracket of the utility model in the left and right directions. At the same time, the spring arrangement between the clamping blocks 1310 can also be used to compensate for the displacement of the pipeline 4000 caused by thermal expansion, ensuring that the pipeline system can still maintain a suitable position when the temperature changes.

[0037] The support and hanger of the utility model is made of alloy material, which ensures firmness and further ensures stability when the pipeline transports high-temperature media. At the same time, anti-corrosion materials are sprayed on the outside to avoid corrosion caused by a large amount of mine dust and moisture in the underground mine environment.

[0038] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
