Abstract
Description
Technical Field
[0001] The utility model relates to a mine underground pipeline fixing bracket, in particular to a mine vertical shaft mud discharge pipeline fixing bracket. Background Art
[0002] Due to the extension of underground mining and production, especially the continuation of deep production, the amount of deep water has increased significantly. This part of the water generally needs to be introduced into the sedimentation tank through the underground pipeline for sludge sedimentation, and the sewage generated by the subsequent overflow needs to be relayed to the mud discharge system through the underground pipeline, and then transported to the surface clarification tank through the underground pipeline. Taking the Xishan mining area of Sanshan Island Gold Mine as an example, the deep water is first led to the -960 sedimentation tank through the underground pipeline for sludge sedimentation. The overflowing water is discharged to the -1140 water tank through the drainage hole for centralized drainage. The two sludge sedimentation tanks are used in rotation. After the debris is precipitated, artificial pulping is carried out. The overflow sewage is relayed to the -435m mud discharge system through the underground pipeline using a high-lift, small-flow slurry pump, and then transported to the surface clarification tank through the underground pipeline.
[0003] The technical difficulty encountered in installing mud discharge pipelines in the shaft is that the shaft is equipped with other facilities including compressed air water supply, drainage, wire rope tank cages and cables, and the space for mud discharge pipeline installation is relatively narrow. Based on the above reasons, the current practice is generally to fix the mud discharge pipeline at the wellhead position, and the mud discharge pipeline is in a suspended state in the shaft. The main defects of this approach are: first, it occupies the wellhead space and affects other operations; second, the mud discharge pipeline is shaken or even swung by the impact of mud and sand in the shaft, which is easy to collide and damage surrounding facilities. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a mine shaft mud discharge pipeline fixing bracket, which utilizes the narrow space in the shaft to fix the mud discharge pipeline in the shaft, avoids occupying the wellhead space and keeps the mud discharge pipeline in a stable state all the time.

[0007] Furthermore, the clamping block has a curved inner concave surface on one side thereof which is used to lean against the mud discharge pipeline.
[0008] Furthermore, a support plate for supporting the outer clamping block from the bottom is fixed on the inner side of the outer fixing plate.
[0009] Furthermore, a fixing block is installed on the U-bolt on the upper side of the I-beam; the fixing block is provided with a transverse through hole at the front and rear and a sunken fixing block; the U-bolt on the upper side of the I-beam passes through the transverse through hole; the outer side of the fixing block rests on the flange plate of the I-beam, and the inner side rests on the side of the fixing nut on the U-bolt.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] First, the utility model clamps the mud discharge pipeline by squeezing the clamping block through the external fixing plate, and firmly fixes the mud discharge pipeline on the I-beam by tightening the U-bolt. It has the characteristics of compact structure, high space utilization and reliable connection.

[0018] The present invention is further described below in conjunction with the embodiments and drawings.
[0019] like Figure 1 and Figure 2 As shown, the embodiment of the mud discharge pipeline fixing bracket of the utility model includes an I-beam 10 located on one side of the mud discharge pipeline 9 and fixed at both ends to the wall of the vertical shaft. The direction of the I-beam 10 is perpendicular to the direction of the mud discharge pipeline 9. An inner fixing plate 4 is arranged outside the I-beam 10.
[0020] An external fixing plate 5 is provided on the other side of the mud discharge pipeline 9 (ie, the opposite side of the I-beam beam 10 ).
[0021] This embodiment further includes a U-shaped bolt 1 located at the upper and lower sides of the I-beam 10, respectively. The U-shaped bolt 1 passes through the through hole of the inner fixing plate 4, sandwiches the mud discharge pipeline 9 in the middle, and passes through the through hole of the outer fixing plate 5, and a fastening nut 6 is installed at the passing end. The sandwiching of the mud discharge pipeline 9 means that the mud discharge pipeline 9 passes through the middle of the U-shaped bolt 1.
[0022] This embodiment also includes two clamping blocks 8 for clamping and fixing the mud discharge pipeline 9 from both sides, wherein the outer side ( Figure 2 The left side of the middle) is against the web of the I-beam 10, and the outer side of the outer clamping block 8 ( Figure 2 The right side in the middle rests on the outer fixing plate 5.
[0023] When in use, the outer fixing plate 5 is moved to the Figure 2 The clamping block 8 on the right side is squeezed toward the left side, the clamping block 8 on the right side squeezes the mud discharge pipeline 9 toward the left side, and the mud discharge pipeline 9 squeezes the clamping block 8 on the left side toward the left side, so that the clamping block 8 on the left side is closely against the web of the I-beam 10. Finally, the purpose of fixing the mud discharge pipeline 9 to the I-beam 10 is achieved.
[0024] Furthermore, one side of the clamping block 8 that is used to lean against the mud discharge pipeline 9 has an arc-shaped inner concave surface to better fit the arc surface of the outer wall of the mud discharge pipeline 9.
[0025] Furthermore, the inner side of the outer fixing plate 5 ( Figure 2 A support plate 7 is fixed to the left side of the middle portion for supporting the outer clamping block 8 from the bottom side.
[0026] Furthermore, a fixing block 3 is installed on the U-bolt 1 on the upper side of the I-beam 10. Figure 3 The fixing block 3 is provided with a transverse through hole 3-2 at the front and rear and a sunken fixing block 3-1. The U-bolt 1 on the upper side of the I-beam 10 passes through the transverse through hole 3-2. The outer side of the fixing block 3-1 ( Figure 2 The left side of the middle part of the fixing block 3 is against the flange plate of the I-beam 10, and the inner side is against the side of the fixing nut 2 on the U-bolt 1. The fixing nut 2 is used to fix the fixing block 3.
[0027] The purpose of this design is to use the U-bolt 1 on the upper side of the I-beam 10 to cooperate with the fixing block 3 to increase the contact area with the I-beam 10 and facilitate the leveling of the device to avoid installation tilt. At the same time, the U-bolt 1 on the upper side of the I-beam 10, the inner fixing plate 4, the fixing block 3 and the fixing nut 2 are used to more stably fix the part on the I-beam 10. The clamping block can be replaced in size and can adapt to mud discharge pipes of different calibers. The position and direction of the clamping block can be adjusted more conveniently.
[0028] In this embodiment, the U-bolt 1 is made of 20mm round steel and has an M20 coarse thread; the clamping block 8 is made of pine wood block. After being installed in the mud discharge pipe 9 and before being tightened, the gap between the two clamping blocks 8 is about 30mm. After tightening the mounting nut 6, the gap between the two parts is controlled within 15mm.
[0029] All metal structure surfaces are manually derusted and painted with two coats of epoxy zinc-rich primer and epoxy asphalt black topcoat to maximize their service life and delay the corrosion of metal materials by water in the air intake shaft and chloride ions in the humid air.
