Description

Technical Field

[0001] This utility model relates to the field of fracturing pipe blasting, and in particular to a liquid oxygen fracturing rock pipe terminal seal. Background Technology

[0002] Gas fracturing tubes utilize the thermal expansion of gas, which is then rapidly released at high pressure to break rocks or cause coal to fall. Due to their controllable expansion capacity, high power, and lack of shockwave generation, they are widely used in urban redevelopment, construction, and mining. Currently, in existing technologies, the connection between the gas pipe and the electrical wire of a gas fracturing tube and the main body of the tube requires sealing to prevent sand, air, etc., from entering the tube body through the gaps between the gas pipes, thus ensuring product quality and blasting effect. However, the current sealing method involves manually wrapping the gas pipe and electrical wire with tape, starting from the gas pipe end and extending to the main body, then injecting glue between the gas pipes to achieve a seal. This method is inconvenient, and manual construction has a certain failure rate; if the tape is not wrapped tightly, the seal may fail. Utility Model Content

[0003] The purpose of this invention is to provide a liquid oxygen-induced fracturing rock pipe terminal seal.

[0004] The technical solution to achieve the purpose of this utility model is: a liquid oxygen fracturing rock pipe terminal seal, comprising a sealing plastic pipe, a sealing sleeve, and a positioning cable tie; the sealing plastic pipe is sleeved on the fracturing rock pipe pipeline; the sealing sleeve is disposed inside the sealing plastic pipe and seals and isolates the axial ends of the fracturing rock pipe pipeline; the positioning cable tie is sleeved on the outer surface of the sealing plastic pipe and directly fixes and seals the sealing plastic pipe and the sealing sleeve.

[0005] The sealing sleeve is provided with pipe holes and wire holes for the rock-cracking pipe to pass through.

[0006] The sealing sleeve is composed of a left half and a right half.

[0007] The sealing sleeve has a glue injection groove connecting the pipe hole and the wire hole; the glue injection groove has a glue injection hole extending to the outer periphery of the sealing sleeve.

[0008] The sealing sleeve has a positioning groove on its outer periphery.

[0009] By adopting the above technical solution, this utility model has the following beneficial effects: This utility model has an ingenious structure. The gap between the pipelines of the fracturing tube can be sealed by the sealing tube, the sealing sleeve, and the positioning strap, which prevents sand and air from entering the fracturing tube body. The operation is more convenient and the sealing effect is good. The sealing sleeve seals the gas tube and the wire and fixes their position, which effectively improves the stability of the fracturing tube. It can reduce the friction between the gas tube and the wire, making it less likely to be damaged and less likely to cause short circuit in the fracturing tube, thus better ensuring the product quality and detonation effect of the fracturing tube.

[0012] Example

[0013] See Figures 1 to 4 The liquid oxygen fracturing rock pipe terminal seal of this embodiment includes a sealing plastic tube 1, a sealing sleeve 2, and a positioning cable tie 3. The sealing plastic tube 1 is fitted onto the fracturing rock pipe. The sealing sleeve 2 is disposed inside the sealing plastic tube 1 and seals and isolates the axial ends of the fracturing rock pipe. The positioning cable tie 3 is fitted onto the outer surface of the sealing plastic tube 1 and directly fixes and seals the sealing plastic tube 1 and the sealing sleeve 2.

[0014] See Figure 2 and Figure 3The sealing sleeve 2 has two pipe holes 2-1 and two wire holes 2-2 for the pipeline of the rock-fracturing tube. The wire hole 2-2 is located between the two pipe holes 2-1. The sealing sleeve 2 is composed of a left half 2-3 and a right half 2-4. When the left half 2-3 and the right half 2-4 of the sealing sleeve 2 are separated, the wire hole 2-2 is on each half of the left half 2-3 and the right half 2-4. A glue injection groove 2-5 is provided between the pipe hole 2-1 and the wire hole 2-2 of the sealing sleeve 2, connecting the pipe hole 2-1 and the wire hole 2-2. The glue injection groove 2-5 has a glue injection hole extending to the outer periphery of the sealing sleeve 2. A positioning groove 2-6 is provided on the outer periphery of the sealing sleeve 2. The sealing plastic tube 1 is made of flexible material. The positioning strap 3 squeezes the outer wall of the sealing plastic tube 1, so that the inner wall of the sealing plastic tube 1 is tightly attached to the outer wall of the sealing sleeve 2, achieving a sealing effect.

[0015] In use, the left half 2-3 and the right half 2-4 are fitted onto the pipeline of the cracking tube, so that the inner walls of the pipe hole 2-1 and the wire hole 2-2 are respectively attached to the outer surface of the pipeline of the cracking tube. Glue is injected through the injection hole, and the glue flows through the injection groove 2-5 through the inner walls of the pipe hole 2-1 and the wire hole 2-2, filling their inner walls and the outer surface of the pipeline of the cracking tube. The sealing plastic tube 1 is fitted onto the pipeline of the cracking tube. The positioning strap 3 is used to attach the sealing plastic tube 1 to the positioning groove 2-6 of the sealing sleeve block 2, and the sealing plastic tube 1 and the sealing sleeve block 2 are pressed to fit precisely, so as to seal the gap between the sealing plastic tube 1 and the pipeline of the cracking tube, so that sand, air and other particles cannot enter the other end of the sealing plastic tube 1 through the gap between the pipeline of the cracking tube.
