Problems solved by technology

[0003] During normal connection and use, although the connection of the current pipe joints is relatively reliable, due to the high pressure of the delivered gas, once the pipe joints fall off, it will cause the end of the gas pipe to fly, which may cause casualties. Security cannot be guaranteed
At present, steel wire ropes are mainly used to connect the two ends, but the process of fixing and removing the wire ropes is time-consuming and laborious, and the efficiency is low

Embodiment 1

[0039] see Figure 1-9 , the mine adopts the safety protection structure of the flexible gas pipe joint, which includes a flexible gas pipe body, and the end part of the flexible gas pipe body is fixedly installed with a pipe joint 4 through a winding wire 5, and the ends of the two adjacent pipe joints 4 are installed. The head part is connected by the butt joints of the locking hoop 6, and is provided with a sealing gasket at the end faces of the two, and the outer casing 3 of the flexible gas delivery pipe body exceeds a length of the pipe joint 4, and the excess part is symmetrically cut and wound into a ring shape. Lap joints are connected by pressing the sleeve 7 at the lap joint to form a connecting ring 10 ; two adjacent connecting rings 10 are connected by a connecting buckle 9 . Through the safety protection structure of the above structure, it is arranged at the joint of the flexible gas delivery pipe, which can connect the two ends of the pipe joint reliably, there...

Embodiment 2

[0044] The production method of the safety protection structure of the flexible gas pipeline joint for mine development includes the following steps:

[0045] Step 1: Prepare two flexible gas pipe bodies that need to be docked;

[0046] Step 2: Since the outer sleeve 3 is made of a braided layer of high-strength wear-resistant fiber material, which is wrapped on the outside of the pressure-bearing inner tube 1 and the air-tight inner tube 2, the ends of the outer sleeve 3 are symmetrically cut to form a shear incision 12;

[0047] Step 3: Cut and trim the end parts of the two flexible gas pipeline bodies to be connected, cut off the pressure-bearing inner tube 1 and the air-tight inner tube 2 at the cutting opening 12, and only keep the symmetrically cut outer sleeve 3. , so that the end portion of the outer casing 3 of the flexible gas delivery pipe body is beyond the pressure-bearing inner pipe 1 and the airtight inner pipe 2 within a section of length to form a reserved ca...

Abstract

The invention provides a safety protection structure and a manufacturing method of a flexible gas transmission pipe joint used in mine openings, which comprises a flexible gas transmission pipe body, and the end of the flexible gas transmission pipe body is fixedly installed with a pipe joint through winding wires, and two adjacent pipes are installed with a pipe joint. The end parts of the joint are connected by a locking hoop, and a sealing gasket is arranged on the end faces of the two. In the lap joint, the lap joint is connected by a sleeve pressing button to form a connecting ring; the two adjacent connecting rings are connected by a connecting button. The safety protection structure is arranged at the joint of the flexible gas pipe, which can connect the two ends of the pipe joint reliably, thereby effectively preventing the problem of flying of the pipe end caused by the falling off of the gas pipe joint, and ensuring the safety of the connection.

Description

technical field [0001] The invention relates to the technical field of mine blasting and mining safety protection, in particular to a safety protection structure and a manufacturing method of a flexible gas transmission pipe joint used in mine development, which is suitable for large-scale mine blasting and mining. Background technique [0002] In the process of mining, it is necessary to use rock drilling equipment for drilling. At present, the main operation method is down-the-hole impactor. The down-the-hole impactor mainly adopts the centralized gas supply mode. The flexible gas delivery pipe is used as the gas delivery pipe, and the flexible gas delivery pipe mainly adopts the novel high-pressure flexible gas delivery pipe disclosed in CN 207268339 U, which was previously applied for by the company. The flexible gas delivery pipe mainly adopts a three-layer structure, including an airtight inner pipe 2, Pressure bearing pipe 1 and outer casing 3. In order to realize lo...
