Technical Field
[0001] This utility model relates to the field of mining pipeline technology, specifically to a wear-resistant mining pipeline that is easy to connect. Background Technology
[0002] A mine refers to an independent production and operation unit that extracts ore within a defined mining boundary. A mine mainly includes one or more mining workshops and some auxiliary workshops. Most mines also include ore dressing plants. Mines include coal mines, metallic mines, non-metallic mines, building material mines, and chemical mines, etc.
[0003] Chinese Patent CN213064990U discloses a wear-resistant plastic alloy pipe for easy connection in mining applications. The pipe includes a pipe, a first fixing ring, and a second fixing ring. The inner wall of one end of the pipe is fixedly fitted to the outer side of the first fixing ring. Four insertion posts are fixed in a circular array on one side of the first fixing ring. The inner wall of the other end of the pipe is fixedly fitted to the outer side of the second fixing ring. Four insertion holes are formed in a circular array on one side of the second fixing ring. The four insertion posts and four insertion holes are distributed on opposite sides of the first and second fixing rings, with each pair corresponding to the other. Flanges are fixed to both ends of the pipe, and each flange has six through holes formed in a circular array, with each through hole corresponding to the other. This invention offers the advantages of quick pipe connection and positioning, and easy flange connection and fixation.

Flanges are fixed at both ends of the pipe. Six through holes are opened in a ring array on the two flanges. The through holes on the two flanges are matched one-to-one. However, when the device is used, the pipe is not only used to transport water, but also to transport slurry or dry mineral powder. During the transport, the first and second fixing rings protruding from the inner wall of the pipe will contact and collide with the solid, which will reduce the transport efficiency and damage the fixing rings themselves.

Both ends of the pipe body 1 are connected to the flange 2. The flange 2 has multiple through holes arranged in a ring array. The flange 2 has an installation groove at the end away from the pipe body 1.
[0022] In an optional embodiment, an annular groove 12 is provided on the flange 2 at either end of the pipe body, and an annular protrusion 13 corresponding to the annular groove 12 is provided on the other flange 2.
[0023] The auxiliary connection assembly consists of a first connector and a second connector. The first connector consists of a first fixing ring 3 and a guide rod 4. The first fixing ring 3 is detachably connected to the mounting groove on any flange 2, and multiple guide rods 4 arranged in a ring array are connected to the first fixing ring 3. The second connector consists of a second fixing ring 5, which is detachably connected to the mounting groove on another flange 2. The second fixing ring 5 has a receiving groove 6 corresponding to the guide rod 4. When the auxiliary connection assembly is in use, adjacent pipe bodies 1 are close to each other, and the guide rod 4 on the first fixing ring 3 and the mounting groove on the second fixing ring 5 cooperate to restrict the position of adjacent pipe bodies 1.
[0024] Example 2
[0025] like Figures 2-5 As shown, this utility model proposes a mine wear-resistant pipe that is easy to connect. Compared with Embodiment 1, this embodiment describes the detailed structure of the auxiliary connection components.

[0027] In an optional embodiment, the guide rod 4 consists of a rod body 8 and a conical block 9. The rod body 8 is connected to the flange 2, and the conical block 9 has a through hole through the rod body 8. The conical block 9 is sleeved on the outside of the rod body 8. The conical block 9 can guide the guide rod 4 when it is inserted into the receiving groove 6, and the shape of the receiving groove 6 allows the guide rod 4 to slide and match it.
[0028] In an optional embodiment, the centerlines of the plurality of rods 8 are angled at 120°, and the diameter of any one rod 8 is smaller than the diameter of the other two rods 8, which are located in the bottom area of the pipe body 1. When the pipe body 1 is transporting, under the action of gravity, the liquid containing minerals or minerals are close to the bottom of the pipe body 1, so it is necessary to maintain a large number of rods 8 in the bottom area of the pipe body 1 to enhance its strength.
