Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This embodiment provides a technical solution: a mine shotcrete pipe, including an outer rubber layer 1, with uniformly distributed grooves on the outer surface of the outer rubber layer 1, the outer rubber layer 1 being a wear-resistant rubber layer, and an inner rubber layer 2 inside the outer rubber layer 1, the inner rubber layer 2 being a composite layer of synthetic rubber and nanomaterials, a spiral guide groove 3 fixedly connected to the inner surface of the inner rubber layer 2, uniformly distributed steel wire ropes 6 fixedly connected between the inner rubber layer 2 and the outer rubber layer 1, and uniformly distributed spiral connecting steel wires 5 fixedly connected between the steel wire ropes 6, the spiral connecting steel wires 5 and the steel wire ropes 6 forming multiple triangular structures, improving the overall toughness and strength of the shotcrete pipe. During mine shotcrete operations, the external pipe injects slurry into the interior of the shotcrete pipe, and after being transported by the shotcrete pipe, it reaches a specific position and is sprayed out. Under the action of the spiral guide groove 3, the flowing slurry forms a swirling flow along the axial direction of the shotcrete pipe, reducing the vertical impact of the fluid on the pipe wall, thereby reducing local turbulence and frictional resistance. It also includes a protective mechanism 4.

[0023] Protective mechanism 4 includes rubber strips 41, rubber rings 42, and nylon retaining rings 43. The outer surface of the outer rubber layer 1 is provided with evenly distributed rubber strips 41. Evenly distributed rubber rings 42 are fixedly connected between the rubber strips 41. Symmetrically distributed nylon retaining rings 43 are fixedly connected to the front and rear sides of the rubber strips 41. The nylon retaining rings 43 are engaged in slots. Protective mechanism 4 also includes nylon elastic blocks 44, locking blocks 46, and insertion blocks 47. Nylon elastic blocks 44 are fixedly connected inside the nylon retaining rings 43. Locking blocks 46 are fixedly connected to the inner arc surface of nylon elastic blocks 44. Slots are provided inside the nylon retaining rings 43, and insertion blocks 47 are inserted into these slots. Evenly distributed locking grooves are provided on the upper surface of insertion blocks 47, and these grooves are all fitted with locking blocks 46. Protective mechanism 4 also includes a prying mechanism. Block 45 is fixedly connected to the outer arc surface of the nylon elastic block 44. The rubber strip 41 and rubber ring 42 form a protective layer on the outer rubber layer 1. When the spray pipe rubs against the outside, the rubber strip 41 and rubber ring 42 are worn first to prevent wear on the outer rubber layer 1 of the spray pipe. When the rubber strip 41 and rubber ring 42 are severely worn and need to be replaced, the actuating block 45 is moved to move the nylon elastic block 44, causing the locking block 46 to separate from the slot. The insertion block 47 is pulled out from the slot, thereby removing the rubber strip 41 and rubber ring 42 and replacing them with new ones. The nylon fixing ring 43 is snapped into the slot, and the insertion block 47 is inserted into the slot. The locking block 46 is snapped into the slot until the insertion block 47 is fully inserted into the slot, completing the replacement of the rubber strip 41 and rubber ring 42.

[0024] The working principle of the shotcrete pipe for mining provided by this utility model is as follows: During shotcrete operations in mining, the external pipeline injects slurry into the interior of the shotcrete pipe. After being transported by the shotcrete pipe, it reaches a specific position and is sprayed out. Under the action of the spiral guide groove 3, the flowing slurry forms a swirling flow along the axial direction of the shotcrete pipe, reducing the vertical impact between the fluid and the pipe wall, thereby reducing local turbulence and frictional resistance. The spiral connecting steel wire 5 and the steel wire rope 6 form multiple triangular structures, improving the overall toughness and strength of the shotcrete pipe. The rubber strip 41 and rubber ring 42 form a protective layer on the outer rubber layer 1. When the shotcrete pipe rubs against the outside, it preferentially... Wearing rubber strip 41 and rubber ring 42 is performed to prevent wear on the outer rubber layer 1 of the spray pipe. When rubber strip 41 and rubber ring 42 are severely worn and need to be replaced, the actuating block 45 is moved to move nylon elastic block 44, causing the locking block 46 to separate from the slot. The insertion block 47 is then pulled out of the slot, thereby removing rubber strip 41 and rubber ring 42. New rubber strip 41 and rubber ring 42 are then replaced. Nylon fixing ring 43 is snapped into the slot, and insertion block 47 is inserted into the slot. Locking block 46 engages with the slot until insertion block 47 is fully inserted into the slot, completing the replacement of rubber strip 41 and rubber ring 42.

[0025] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
