Abstract
Description
Technical Field
[0001] This invention relates to the technical field of pipeline installation equipment, and in particular to an auxiliary device and method for pipe threading operations inside a pipe jacking system. Background Technology
[0002] In the construction of heating pipelines, a jacking pipe is first installed on the outside of the heating pipeline, and then the heating pipeline is installed inside the jacking pipe. In the pipeline installation process after the jacking pipe is installed, the jacking pipe has a diameter of 1600mm, and the heating pipeline has a diameter of 1200mm and a length of 12 meters. The welded heating pipeline needs to be threaded through the jacking pipe to achieve continuity. However, the internal space of the jacking pipe is narrow, making it impossible to use a crane to lift the heating pipeline into the jacking pipe. Existing construction methods lack specialized equipment suitable for the jacking pipe and pipeline dimensions, resulting in high difficulty and low efficiency in the pipeline threading operation, seriously affecting the construction progress. Summary of the Invention
[0003] In order to solve the problems existing in the prior art, the present invention provides an auxiliary device and method for pipe laying operation in pipe jacking.
[0004] On the one hand, the present invention provides an auxiliary device for pipe threading operations inside pipe jacking, which adopts the following technical solution: A pipe-laying auxiliary device for pipe jacking includes a jacking pipe, a pipe support plate, and a heating pipe. The pipe support plate is located between the bottom of the heating pipe and the bottom wall of the jacking pipe. The bottom of the pipe support plate is provided with a movable component that can roll on the inner wall of the jacking pipe. Multiple pipe support plates are evenly distributed along the length of the heating pipe.
[0005] Optionally, the moving component includes multiple steel balls embedded in the bottom of the pipe support plate, which is an arc-shaped steel plate.
[0006] On the other hand, the present invention also discloses a method for using an auxiliary device for pipe threading operations in pipe jacking, comprising the following steps: S1. Place the pipe support plate on the outer wall of the heating pipe, so that the pipe support plate is below the heating pipe, and multiple pipe support plates are evenly distributed along the length of the heating pipe. S2. The heating pipe is dragged by an external traction device, causing the steel balls under the pipe support plate to roll along the inner wall of the jacking pipe, thereby smoothly inserting the heating pipe into the jacking pipe and achieving connection.
[0007] Compared with the prior art, the present invention has the following technical effects: Adaptable to confined spaces, the device is designed to fit the clearance between the jacking pipe and the heating pipe, allowing for smooth operation within narrow spaces and solving the problem of crane-impacted lifting. Steel balls convert sliding friction into rolling friction, significantly reducing the traction force required for dragging; this simplifies the installation process of heating pipes within the jacking pipe, reduces manpower and material consumption, and accelerates construction progress. Constructed with thick-walled arc-shaped steel plates and high-strength steel balls, the structure boasts high strength, adaptability to the complex working environment within the jacking pipe, and a long service life.

[0009] Explanation of reference numerals in the attached diagram: 1. Pipe support plate; 2. Steel ball; 3. Heating pipe; 4. Jacking pipe. Detailed Implementation
[0010] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 The present invention will be described in further detail below.
[0011] Reference Figures 1-3 This invention discloses an auxiliary device for pipe installation in a jacking pipe, comprising a jacking pipe 4, a pipe support plate 1, and a moving assembly. The pipe support plate 1 is an arc-shaped steel plate, and its curvature matches that of the heating pipe 3, ensuring stable support for the heating pipe 3. The length of the pipe support plate 1 is adapted to the operational requirements of the pipe, and its width is designed according to the gap between the jacking pipe 4 and the heating pipe 3 (jacking pipe diameter 1600mm, heating pipe 3 diameter 1200mm, gap 200mm), ensuring smooth movement of the device within the jacking pipe 4.
[0012] The moving component includes multiple high-strength steel balls 2 positioned below the pipe support plate 1. These steel balls 2 are embedded in the bottom of the pipe support plate 1 and can rotate. They contact the inner wall of the jacking pipe 4, utilizing their rolling characteristics to convert the sliding friction between the heating pipe 3 and the inner wall of the jacking pipe 4 into rolling friction, thus reducing dragging resistance. The pipe support plate 1 is positioned along the length of the jacking pipe 4, with one plate every 6 meters, ensuring that the heating pipe 3 experiences uniform force and maintains stability during dragging.
[0013] This invention also discloses a method for using an auxiliary device for pipe threading operations inside a pipe jacking system, comprising the following steps: S1. Place the pipe support plate 1 on the outer wall of the heat pipe 3, so that the pipe support plate 1 is below the heat pipe 3, and the multiple pipe support plates 1 are evenly distributed along the length of the heat pipe 3. S2. The heating pipe 3 is dragged by an external traction device, so that the steel ball 2 under the pipe support plate 1 rolls along the inner wall of the jacking pipe 4, thereby smoothly inserting the heating pipe 3 into the jacking pipe 4 and achieving connection.
[0014] The present invention has the following technical effects: 1. Adaptable to narrow spaces: The device is adapted to the size gap between the jacking pipe 4 and the heating pipe 3, and can operate smoothly in the narrow space of the jacking pipe 4, solving the problem that cranes cannot lift the pipes.
[0015] 2. Reduce drag resistance: Steel ball 2 converts sliding friction into rolling friction, which greatly reduces the traction force required for dragging, reducing construction difficulty and equipment wear.
[0016] 3. Ensure pipeline stability: Install a device every 6m to ensure that the heating pipeline 3 is subjected to uniform force during dragging, and avoid pipeline displacement, jamming or deformation.
[0017] 4. Improved work efficiency: The installation process of the internal heating pipe 3 of the pipe jacking 4 is simplified, reducing the consumption of manpower and material resources and accelerating the construction progress.
[0018] 5. Robust and durable structure: Made of 20mm thick arc-shaped steel plate and high-strength steel balls, the structure has high strength and can adapt to the complex working environment inside the pipe jacking, with a long service life.
[0019] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
