Description

Technical Field

[0001] The utility model relates to the technical field of filling pipelines, in particular to a clamp type joint for mine filling pipelines. Background Art

[0002] Backfill mining refers to a mining method that uses backfill materials to fill the goaf during ore dropping, transportation and other operations. The purpose of backfilling is to support the rocks on both sides of the goaf and to create a base for continued stratified mining above. It is suitable for deposits where the ore and surrounding rock are unstable and no large exposed surface is allowed, deposits that need to be protected on the surface, deposits of rare precious metals or high-grade, sulfide deposits with spontaneous combustion, and deposits with complex occurrence conditions. Among them, the commonly used backfilling method is the cementing backfilling method, which uses crushed stone, river sand, tailings, and Gobi aggregate as aggregates, and mixes them with cement and other cementitious materials to form a paste or slurry, which is pumped through pipes or transported to the backfill area by gravity flow.

[0003] After the filling pipeline is installed, it may be affected by the external environment and produce a certain impact on the pipeline itself, causing the pipeline to vibrate. In addition, when the material is transported inside the filling pipeline, the internal material has strong impact force and fast flow rate, which will increase the pressure on the pipeline connection, thereby causing the connection to vibrate. At present, the connection of the filling pipeline is mostly connected by a clamp-type joint, which is fixed by bolts. In actual use, the bolts will become loose, affecting the stability of the pipeline connection.

[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0026] See also Figure 1-Figure 3 Moreover, a screw 15 is provided through the interior of the fixed block 9 and the auxiliary block 11 of the utility model, and the screw 15 can control the movement of the auxiliary block 11.

[0027] See also Figure 1-Figure 4 Better yet, the screw 15 of the utility model is rotatably connected to the fixed block 9, and the screw 15 is threadedly connected to the auxiliary block 11.

[0029] The working principle of this utility model:

[0030] First, the staff will place the pipeline to be connected in the groove 3 and seal it with the sealing ring 4. Then, the upper clamp 1 and the lower clamp 2 are abutted, and the first connecting block 5 and the second connecting block 6 are connected by the bolt 7. At this time, it is necessary to rotate the screw 15 first. The rotation of the screw 15 drives the auxiliary block 11 to move downward. When the auxiliary block 11 moves to the bottom of the bolt 7, the rotation of the screw 15 can be stopped. At this time, it is convenient to connect the nut 8 with the bolt 7. After the nut 8 and the bolt 7 are connected, the screw 15 is rotated in the opposite direction so that the screw 15 drives the auxiliary block 11 to move upward. When the abutment plate 13 on the auxiliary block 11 abuts against the bottom surface of the nut 8, the rotation of the screw 15 can be stopped. At this time, the abutment between the abutment plate 13 and the nut 8 can prevent the nut 8 from moving downward due to vibration, so that the nut 8 can be better and stably connected with the bolt 7, thereby improving the stability of the nut 8 and the bolt 7 when subjected to vibration.
