Problems solved by technology

There are many ways to connect pipes. Commonly used connection methods include threaded connection, flange connection, welding, threaded connection, etc. When connecting pipes with small diameters, some pipe joints with threaded threads are generally used. In the process, it is often necessary to replace the old pipe and install a new pipe. Since the pipe is in a difficult-to-operate working position and there is no action point for disassembly tools outside, it is difficult to directly disassemble and install the pipe with ordinary disassembly and installation tools.
[0003] At present, there are not many dismantling pipe buckle devices in China, and they are mainly tools for replacing or installing all pipes after they are removed from the working position. This installation and disassembly process is not only time-consuming, but also increases the labor intensity of workers. The most important What is more important is that for some time-critical projects, the more time wasted, the greater the economic loss it will cause
To disassemble and install the pipe buckle, there is currently no tool for dismantling the old pipe buckle or installing a new pipe buckle in the pipeline

Embodiment example 1

[0018] As shown in Figure 1-Figure 5, a pipe buckle installation and removal device in the pipe is mainly composed of a stepped shaft 1, an adjustment nut 2, a baffle plate 3, a thrust ball bearing 4, a set screw 5, a limit block a6, and a slip base a7, slips 8, spring 9, slip base 10, limit block b11, lock nut 12, lock nut 13;

[0019] It is characterized in that: a pipe buckle installation and disassembly device in the pipe, mainly composed of a stepped shaft 1, an adjusting nut 2, a baffle plate 3, a thrust ball bearing 4, a set screw 5, a limit block a6, a slip base a7, and a slip 8 , spring 9, slip base 10, limit block b (11), lock nut 12, lock nut 13;

[0020] It is characterized in that: the stepped shaft 1 is composed of a hexagonal 1a, a spline shaft 1b, a first adjusting thread 1c and a second adjusting thread 1d, wherein the hexagonal 1a is in the shape of a hexahedron; the shape of the adjusting nut 2 is stepped, adjusting The middle section of the step of the nut...

Embodiment example 2

[0023] The installation and removal pipe buckle device in a pipe is characterized in that the disassembly process is as follows: the adjusting nut 2 is threadedly connected with the stepped shaft 1, and moves axially on the stepped shaft 1 by rotation, pushing the thrust ball bearing 4 to move axially, and the thrust ball Bearing 4 pushes the slip base a7 to move along the spline shaft 1b in the stepped shaft 1, the slip base b10 is locked on the stepped shaft 1 by the lock nut 12 and the lock nut 13 together, and the slip base a7 pushes The slip 10 moves upward along the dovetail guide groove 7a of the slip base a7 and the dovetail guide groove 10a of the slip base b10 to contact the limit ring a6 and the limit ring b11 until the adjusting nut 2 can no longer be screwed. Clamp the inner wall of the dismantled pipe, and then turn (manual wrench, electric motor, hydraulic drive, etc.) to turn the hexagon 1a on the stepped shaft 1 to remove the dismantled pipe from the working po...

Abstract

The invention relates to a device for installing and removing pipe buckles in pipes in the field of connecting and dismounting devices for pipes. The adjusting nut and the stepped shaft are connected by threads, the top of the adjusting nut step is connected with the bottom of the baffle step as clearance fit, the top of the baffle step and the slip base a are connected by set screws, and the slip base a and slip base b are installed In the spline shaft section of the stepped shaft, the slips are installed in the dovetail guide grooves on the slip base a and slip base b. The base b is the step at the bottom, the limit ring a and the limit ring b are in interference connection with the slip base a and the slip base b, and the lock nut, lock nut and the stepped shaft are all threaded, and the slips The tail of the base b is tight. The device is used for dismantling broken pipes and installing new pipes in pipelines. It is not necessary to remove two connected pipelines from the working position at the same time, which is convenient for workers to operate, reduces replacement costs, and reduces pipeline replacement time.

Description

technical field [0001] The invention relates to the field of petroleum equipment, in particular to a device for installing and removing pipe buckles in coiled tubing. Background technique [0002] In daily production and life, metal pipes are widely used in many industries and have been widely used in oil refining, chemical industry, nuclear power, thermal power, ships, military industry, construction, aviation, electronics, food, pharmaceuticals, textiles and transportation industries. The pipeline system has become the core component of the pipe equipment in the pipeline system. Such as coiled tubing used in oil and gas exploitation, tap water pipes in daily life, etc. There are many ways to connect pipes. Commonly used connection methods include threaded connection, flange connection, welding, threaded connection, etc. When connecting pipes with small diameters, some pipe joints with threaded threads are generally used. In the process, it is often necessary to replace t...
