Description

Technical Field

[0001] The utility model relates to the technical field of pipeline butt joint, in particular to a pipeline butt joint device used in municipal construction. Background Art

[0002] At present, municipal gas pipes mostly use PE gas pipes for gas transportation. In the process of laying gas pipes, docking equipment is often needed to hot-melt dock the gas pipes. However, when using the docking equipment in the prior art, construction workers are required to first fix the pipe on the docking equipment, and then manually cut the end of the pipe. After cutting, the cut port is hot-melt treated with a hot-melt device, and finally manually press the docking. Obviously, this will not only reduce the efficiency of the pipe docking operation, but also cause the pipe incision to be exposed to the air for a long time, thereby affecting the quality of the pipe docking. Utility Model Content

It has the advantages of being able to effectively shorten the time that the incision is exposed to the air and effectively improve the docking quality.

[0005] Preferably, the hot melt butt joint mechanism includes a fixed bracket arranged in the middle of the butt joint platform, the fixed bracket is slidably connected to a mounting frame, a cutting tool is detachably mounted on the mounting frame, an electric heating plate is arranged above the cutting tool, and a driving cylinder for driving the mounting frame to move up and down is arranged above the fixed bracket. When the mounting frame moves downward under the action of the driving cylinder, the cutting tool will cut the PE pipe body, thereby ensuring the flatness of the butt joint surface.

[0006] Preferably, the two clamping assemblies are respectively threadedly matched with the two threaded sections of the bidirectional screw rod. When the bidirectional screw rod rotates around its own axis, the two clamping assemblies will approach each other, thereby clamping and limiting the PE pipe body.

[0007] Preferably, two sliding bases are symmetrically arranged, and the electric telescopic rods are symmetrically arranged on both sides of the horizontal slide rail. During the pipeline docking operation, the two sliding bases will approach each other under the action of the electric telescopic rods.

[0020] Embodiment 1

[0021] When the docking equipment in the prior art is used, the construction workers are always required to assist, which is not only inefficient, but also causes the pipe cut to be exposed to the air for a long time, which may affect the quality of the pipe docking. In order to solve this technical defect in the prior art, Figure 1-Figure 4As shown, this embodiment proposes a pipeline docking equipment for municipal construction, which can automatically position and transport the PE pipe body 3 and apply a certain pressure to the PE pipe body 3 during the hot melting process without manual operation by construction personnel. The equipment docking platform 1 is symmetrically equipped with a pipeline limiting mechanism 2 for transporting the PE pipe body 3. A hot melting docking mechanism 4 for cutting and heating the PE pipe body 3 is arranged in the middle of the docking platform 1. When the pipelines are docked, the pipeline limiting mechanism 2 will transport the two PE pipe bodies 3 to the two sides of the hot melting docking mechanism 4 respectively. Next, the hot melting docking mechanism 4 will perform hot melting docking operations on the PE pipe body 3. Specifically, the pipeline limiting mechanism 2 comprises a horizontal slide rail 201 fixedly mounted on the docking platform 1, a sliding base 202 is movably mounted on the horizontal slide rail 201, a clamping assembly 203 is symmetrically mounted on the upper end of the sliding base 202, the two clamping assemblies 203 are respectively threadedly matched with the two threaded sections of the bidirectional screw rod 204, when the bidirectional screw rod 204 rotates around its own axis, the two clamping assemblies 203 are brought close to each other, so as to clamp and limit the PE pipe body 3, the bidirectional screw rod 204 for driving the clamping assembly 203 is movably mounted inside the sliding base 202, and a driving motor 205 for rotating the bidirectional screw rod 204 is fixedly mounted outside the sliding base 202, An electric telescopic rod 206 for pushing the sliding base 202 is fixedly installed on the horizontal slide rail 201. When the electric telescopic rod 206 is extended, the sliding base 202 will move horizontally along the horizontal slide rail 201. Specifically, two sliding bases 202 are symmetrically arranged, and the electric telescopic rods 206 are symmetrically arranged on both sides of the horizontal slide rail 201. During the pipe docking operation, the two sliding bases 202 will approach each other under the action of the electric telescopic rods 206. The hot-melt docking mechanism 4 includes a fixed bracket 401 arranged in the middle of the docking platform 1, and a mounting frame 402 is slidably connected to the fixed bracket 401. A cutting tool 403 is detachably installed on the mounting frame 402. Two cutting tools 403 are provided, which can cut two PE pipe bodies 3 at the same time, so as to ensure that the end cuts of the two PE pipe bodies 3 have consistent flatness. An electric heating plate 404 is provided above the cutting tool 403, and a docking area is provided between the cutting tool 403 and the electric heating plate 404. After heating, the two PE pipe bodies 3 will be hot-melt docked in the docking area. A driving cylinder 405 for driving the mounting frame 402 to move up and down is provided above the fixed bracket 401. When the mounting frame 402 moves downward under the action of the driving cylinder 405, the cutting tool 403 will cut the PE pipe body 3, so as to ensure the flatness of the docking surface.

[0022] In this embodiment, when the municipal construction personnel connect the PE pipe body 3, Figure 1As shown, first, the two PE pipe bodies 3 that need to be connected are placed on the upper end of the sliding base 202 respectively, and the position of the PE pipe body 3 is adjusted. Then, the clamping components 203 located on both sides of the PE pipe body 3 are moved closer to each other under the action of the bidirectional screw rod 204, thereby clamping and limiting the PE pipe body 3.

[0023] Next, the two sliding bases 202 will approach each other under the drive of the electric telescopic rod 206, thereby moving the two PE pipe bodies 3 to the inside of the fixed bracket 401 at the same time. Subsequently, the installation frame 402 will move downward rapidly under the action of the driving cylinder 405. When the installation frame 402 moves downward, the cutting tool 403 will synchronously cut the ends of the two PE pipe bodies 3 respectively, thereby ensuring the consistency of the incision.

[0024] Subsequently, the electric heating plate 404 will move downward between the two PE pipe bodies 3. At the same time, the PE pipe body 3 will contact the electric heating plate 404 under the action of the sliding base 202, thereby completing the hot melt processing.

[0025] After a preset time, the installation frame 402 will move upward a certain distance so that the PE pipe body 3 is located in the docking area. Next, the two PE pipe bodies 3 will be in close contact under the action of the electric telescopic rod 206, thereby completing the pipeline docking operation.

[0026] This embodiment provides a pipeline limiting mechanism 2, and utilizes the mutual cooperation between the sliding base 202 and the clamping assembly 203 to automatically position and transport the PE pipe body 3, and applies a certain pressure to the PE pipe body 3 during the hot-melt process, without the need for manual operation by construction personnel, which can improve the safety of pipeline docking operations and the quality of pipeline docking processing; moreover, this embodiment provides a hot-melt docking mechanism 4, and utilizes the mutual cooperation between the installation frame 402 and the driving cylinder 405 to quickly complete the end cutting and hot-melt docking operations of the PE pipe body 3, effectively shortening the time that the pipeline incision is exposed to the air, which can ensure the quality of pipeline docking and improve the efficiency of docking.

The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
