When installing pipelines in pipeline engineering, multiple sets of pipelines need to be connected. In order to reduce labor intensity and improve pipeline connection efficiency, pipe pulling devices are used to pull the pipelines for connection.

Secondly, existing technologies mostly use fixed installation dimensions, which have certain limitations in use. Furthermore, existing pipe pulling devices often require hoisting equipment to participate in the splicing work, which not only carries certain operational risks but also results in low pipe splicing efficiency.

[0017] Reference Figure 1-4 A pipe pulling device for pipeline engineering includes a slope-adjustable pipe pulling support component 1, with adjustable pipe pulling components 2 detachably connected to both ends of the slope-adjustable pipe pulling support component 1. The number of adjustable pipe pulling components 2 is two sets, and the two sets of adjustable pipe pulling components 2 have the same structure. The adjustable slope-type pipe pulling support assembly 1 includes a pipe pulling docking platform 101. A left slope-type guide plate 102 is fixedly connected to one side of the pipe pulling docking platform 101, and a right slope-type guide plate 103 is fixedly connected to the other side of the pipe pulling docking platform 101. A hydraulic push rod 104 is fixedly connected to the middle of the pipe pulling docking platform 101, and a lateral connecting plate 105 is fixedly connected to one end of the hydraulic push rod 104. First, the positions of the adjustable pipe pulling assemblies 2 at both ends of the adjustable slope-type pipe pulling support assembly 1 are adjusted according to the pipe diameter. The hydraulic push rod 104 inside the pipe pulling docking platform 101... The spacing between the two adjustable pipe-pulling assemblies 2 is adjusted by the lateral connecting plate 105. When the adjustable pipe-pulling assembly 2 pulls the pipe to connect, the pipe is guided by the left slope guide plate 102 and the right slope guide plate 103 on both sides of the pipe-pulling docking platform 101. The pipes on both sides are guided to the pipe-pulling docking platform 101 for docking by the left slope guide plate 102 and the right slope guide plate 103. The slope support is provided for pipes with different inner diameters to avoid wear at the pipe docking point and affect the sealing of the pipe connection. The adjustable tube assembly 2 includes a lateral adjustment support plate 201. Lateral limiting plates 202 are fixedly connected to both sides of the lateral adjustment support plate 201. An internal thread limiting box 203 is fixedly connected to the upper center of the lateral adjustment support plate 201. A screw drive box 204 is fixedly connected to the center of the internal thread limiting box 203. A screw drive motor 205 is detachably connected to the center of one side of the screw drive box 204. A limiting sliding rail 206 is provided at the upper center of the lateral adjustment support plate 201. An internal thread sliding block 208 is movably connected to the upper end of the lateral adjustment support plate 201. A bidirectional threaded drive rod 207 is movably connected to the center of the internal thread limiting box 203. A lifting adjustment rod 209 is fixedly connected to the upper center of the internal thread sliding block 208. An arc-shaped pull rod 210 is detachably connected to the upper end of the lifting adjustment rod 209. A lateral adjustment rod 210 is movably connected to the center of the arc-shaped pull rod 210. The adjusting rod 211 is used to adjust the spacing between the two sets of arc-shaped tie rods 210 according to the pipe diameter, and to adjust the support height of the lifting adjusting rod 209. After adjustment, the two sets of arc-shaped tie rods 210 are used to limit the connection of the two sets of pipes to be connected. After connection, the screw drive motor 205 drives the bidirectional threaded drive rod 207 inside the internal thread limit box 203 through the screw drive box 204. After rotation, the bidirectional threaded drive rod 207 engages with the middle of the two sets of internal threaded sliding blocks 208. After engagement, the internal threaded sliding blocks 208 are pulled by the arc-shaped tie rod 210 and the adjusting rod 211 to connect the two sets of pipes. This method is suitable for pipe pulling operations of different sizes. The synchronous automatic pipe pulling and connecting operation can improve the stability of pipe pulling, the efficiency of connecting, and the accuracy.

[0018] Specifically, there are four sets of hydraulic push rods 104 and two sets of side connecting plates 105. The outer surface of one end of each pair of hydraulic push rods 104 is detachably connected to the middle of one side of the side connecting plate 105. The side connecting plate 105 is pushed synchronously by the two sets of hydraulic push rods 104, which can have good pushing force and pushing accuracy.

[0019] Specifically, the two sides of the pipe-connecting platform 101 are fixedly connected to one side of the left slope guide plate 102 and the right slope guide plate 103, respectively. The left slope guide plate 102 and the right slope guide plate 103 have the same support angle. The pipe is guided by the left slope guide plate 102 and the right slope guide plate 103, which can avoid pipe dragging and wear.

[0020] Specifically, both ends of the bidirectional threaded drive rod 207 are movably connected to the middle of the lateral limiting plate 202, and the outer wall of the bidirectional threaded drive rod 207 is movably connected to the middle of the internal threaded sliding block 208. The bidirectional threaded drive rod 207 can ensure the synchronicity of the sliding of the two sets of internal threaded sliding blocks 208 and improve the clamping stability.

[0021] Specifically, the upper middle part of the horizontal adjustment support plate 201 is movably connected to the lower end of the internal thread sliding block 208 through the limiting slide rail 206. The limiting slide rail 206 restricts the movement track of the internal thread sliding block 208, which can ensure the horizontality of the movement. Specifically, the middle of one end of the screw drive motor 205 is movably connected to the middle of the screw drive box 204, and the middle of the screw drive box 204 is movably connected to the outer wall of the bidirectional threaded drive rod 207. The screw drive motor 205 drives the bidirectional threaded drive rod 207 through the screw drive box 204, which can ensure the coaxiality of the rotation of the bidirectional threaded drive rod 207 and avoid shaking during driving.

[0022] Specifically, the rear middle of the internal thread limit box 203 is movably connected to both ends of the pipe docking platform 101 through the side connecting plate 105 and the hydraulic push rod 104. The side connecting plate 105 and the hydraulic push rod 104 adjust the position of the docking platform 101 to make it suitable for use with pipes of different diameters.

[0023] Working Principle: When pipeline engineering requires pipe pulling and connection, the positions of the adjustable pipe pulling components 2 at both ends of the slope-type adjustable pipe pulling support component 1 are adjusted according to the pipe diameter. First, the spacing between the two sets of arc-shaped tie rods 210 is adjusted via the horizontal adjustment rod 211, and the support height of the lifting adjustment rod 209 is adjusted. After adjustment, the two sets of arc-shaped tie rods 210 are used to limit the connection at the joint of the two sets of pipes to be connected. After connection, the screw drive motor 205 drives the bidirectional threaded drive rod 207 inside the internal thread limit box 203 through the screw drive box 204. After rotation, the bidirectional threaded drive rod 207 synchronously engages with the middle of the two sets of internal threaded sliding blocks 208. After thread engagement, the internal threaded sliding blocks 208 are controlled by the arc-shaped tie rods 210 and the horizontal adjustment rod. 211 Pulls two sets of pipes for docking, suitable for pipe pulling operations of different sizes. The synchronous automatic pipe pulling docking operation can improve the stability of pipe pulling, docking efficiency and accuracy. The hydraulic push rod 104 inside the pipe pulling docking platform 101 adjusts the distance between the two sets of adjustable pipe pulling components 2 through the side connecting plate 105. When the adjustable pipe pulling components 2 pull the pipes for connection, the pipes are guided by the slope guide plate 102 on the left side and the slope guide plate 103 on the right side of the pipe pulling docking platform 101. The pipes on both sides are guided to the pipe pulling docking platform 101 for docking. The slope support is provided for pipes with different inner diameters to avoid wear at the pipe docking point and affect the sealing of the pipe connection.
