Description

Technical Field

[0001] This utility model relates to the field of thermoplastic repair technology, and in particular to a thermoplastic molding repair tube connection auxiliary mechanism. Background Technology

[0002] In the field of pipeline repair, thermoplastic molding repair technology is widely used due to its advantages such as high efficiency and reliability. However, with the increasing requirements for pipeline repair, the shortcomings of traditional connection methods have become more and more obvious. For example, when connecting repair pipes of different diameters, it is often difficult to achieve a stable connection due to the lack of effective adaptation and adjustment methods. In order to improve the quality, efficiency and reliability of thermoplastic molding repair pipe connections and meet the increasingly stringent requirements for pipeline repair, it is urgent to develop a special connection auxiliary mechanism.

[0003] In the existing technology, after the liner is heated, there is no special mechanism to assist in the introduction of the liner during the guiding and repairing of the pipeline. After heating, the liner can only be manually forced into the pipeline to be repaired, which is an extremely laborious task. The installation speed of the liner is extremely slow, which seriously delays the entire pipeline repair process. During the long installation process, a large amount of heat is lost from the liner, resulting in a significant decrease in its plasticity. This situation makes it difficult for the liner to fit tightly with the pipeline to be repaired, and gaps and instability are likely to occur at the connection. Therefore, a thermoplastic molding repair pipe connection auxiliary mechanism is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a thermoplastic repair pipe connection auxiliary mechanism, which aims to improve the problem mentioned in the prior art that "the installation speed of the liner is extremely slow, which seriously delays the entire pipeline repair process, and the heat of the liner will be lost in large quantities, resulting in a significant decrease in its plasticity".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a thermoplastic repair tube connection auxiliary mechanism, including a mounting slide, an auxiliary mechanism on the top of the mounting slide, a guide mechanism on the left side of the auxiliary mechanism, a liner connected inside the guide mechanism, the auxiliary mechanism being composed of a fixing component and an auxiliary component, the auxiliary component including a hollow arc frame, an auxiliary wheel rotatably connected to the inner wall of the bottom of the hollow arc frame, and a fixing disc slidably connected to the inner wall of the hollow arc frame.

[0006] As a further description of the above technical solution: the fixing component includes a connecting plate, and the number of the connecting plates is set in two sets and they fit together. The inner wall of the connecting plate is slidably connected with a pin, and the inner wall of the pin is slidably connected with a limit block.

[0007] As a further description of the above technical solution: the bottom of the cavity arc frame is fixedly connected to the top of the mounting slide, and the auxiliary wheel is in contact with the surface of the liner.

[0008] As a further description of the above technical solution: the bottom of the connecting plate is fixedly connected to the top of the fixed plate, and a handle hole is provided in the middle of the connecting plate.

[0009] As a further description of the above technical solution: the guiding mechanism includes a fixed rod, a mounting bracket is fixedly connected to the left side of the fixed rod, an elastic rod is elastically slidably connected to the inner wall of the mounting bracket, and a support block is fixedly connected to the right side of the elastic rod.

[0010] As a further description of the above technical solution: the guiding mechanism also includes a rotating rod, and a guide block is rotatably connected to the bottom of the rotating rod.

[0012] As a further description of the above technical solution: the surface of the rotating rod is rotatably connected to the inner wall of the mounting bracket.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, through the coordinated operation of structures such as the cavity arc frame, auxiliary wheel, fixed plate, connecting plate, pin, and limiting block, the liner is heated and then guided into the pipeline to be repaired with less effort via the auxiliary wheel. This speeds up the installation of the liner, reduces the heat loss of the liner which leads to poor plasticity, and improves the pipeline repair efficiency.

[0015] 2. In this utility model, the liner can be supported by the coordinated operation of the fixed rod, mounting frame, elastic rod, support block, rotating rod, guide block and other structures. The inclination angle of the liner can be changed by the guide block, so that the liner is kept parallel to the pipeline to be repaired. This makes it easy to place the liner accurately in the correct position in the pipeline to be repaired, reduce the time and workload of adjustment and calibration, and improve construction efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 - Figure 2 One embodiment of this utility model is a thermoplastic repair pipe connection labor-saving mechanism 2, which includes a mounting slide 1. The mounting slide 1 is used for moving and transporting devices and has good support. The top of the mounting slide 1 is provided with the labor-saving mechanism 2, and the left side of the labor-saving mechanism 2 is provided with a guide mechanism 3. The guide mechanism 3 is internally connected to a liner 4. The liner 4 has good plasticity after heating and is used to repair pipes. This is the prior art and will not be described in detail below.

[0024] Reference Figure 1 - Figure 3 The labor-saving mechanism 2 consists of a fixed component and an auxiliary component. The auxiliary component includes a hollow arc frame 201, which has a hollow interior to support the liner tube 4. An auxiliary wheel 202 is rotatably connected to the inner wall of the bottom of the hollow arc frame 201. The auxiliary wheel 202 is used to assist in the introduction of the liner tube 4. A fixed plate 203 is slidably connected to the inner wall of the hollow arc frame 201. The fixed plate 203 serves to seal the hollow arc frame 201 and reduce the temperature loss of the liner tube 4. The bottom of the hollow arc frame 201 is fixedly connected to the top of the mounting slide 1. The auxiliary wheel 202 is in contact with the surface of the liner tube 4.

[0025] Reference Figure 1 - Figure 3The fixing component includes a connecting plate 204. Two sets of connecting plates 204 are provided, and the connecting plates 204 are fitted together and used to fix the plate 203. The inner wall of the connecting plate 204 is slidably connected to a pin 205, which serves to fix the connecting plate 204. The inner wall of the pin 205 is slidably connected to a limit block 206, which is used to lock the pin 205, thereby achieving the effect of sealing the cavity arc frame 201. The bottom of the connecting plate 204 is fixedly connected to the top of the fixing plate 203. A handle hole is opened in the middle of the connecting plate 204, which allows the liner 4 to be guided into the pipeline to be repaired with less effort after being heated by the auxiliary wheel 202, thereby speeding up the installation speed of the liner 4, reducing the poor plasticity caused by heat loss of the liner 4, and improving the repair efficiency of the pipeline.

[0026] Reference Figure 4 The guiding mechanism 3 includes a fixed rod 301, which connects the mounting slide 1 and the mounting frame 302. The mounting frame 302 is fixedly connected to the left side of the fixed rod 301. An elastic rod 303 is elastically slidably connected to the inner wall of the mounting frame 302. Adjusting the elastic rod 303 causes the support block 304 to support the side of the liner 4. The support block 304 is fixedly connected to the right side of the elastic rod 303. The right side of the fixed rod 301 is fixedly connected to the left side of the mounting slide 1. The guiding mechanism 3 also includes a rotating rod 305. Adjusting the rotating rod 305 causes the guide block 306 to adjust the up and down of the liner 4. The guide block 306 is rotatably connected to the bottom of the rotating rod 305. The surface of the rotating rod 305 is rotatably connected to the inner wall of the mounting frame 302. This ensures that the liner 4 is parallel to the pipe to be repaired, making it easier to accurately place the liner 4 in the correct position within the pipe to be repaired, reducing adjustment and calibration time and workload, and improving construction efficiency.

[0027] Working principle: During use, when repairing a pipeline, the installer pushes the installation slide 1 to the pipeline to be repaired, drags the liner 4 into the cavity arc frame 201, and then unfolds and closes the fixing plate 203, causing the two sets of connecting plates 204 to fit together. They are then firmly fixed together by the pin 205 and the limiting block 206, keeping the liner 4 in a closed area to reduce heat loss. The operator then pulls the liner 4 from the other end of the pipeline to be repaired. The auxiliary wheel 202 smoothly pulls the liner 4 into the pipeline, allowing it to be heated and then easily guided into the pipeline for repair via the auxiliary wheel 202. In pipeline repair, the installation speed of the liner 4 is accelerated, reducing heat loss and thus improving the plasticity of the liner 4, thereby increasing the repair efficiency. When misalignment occurs between the liner 4 and the pipeline to be repaired, the operator can adjust the elastic rod 303 to drive the support block 304 to support the side of the liner 4. At the same time, the rotating rod 305 can be adjusted to drive the guide block 306 to adjust the vertical position of the liner 4, ensuring that the liner 4 is parallel to the pipeline to be repaired. This achieves accurate placement of the liner 4 in the correct position within the pipeline to be repaired, reducing the time and workload of adjustment and calibration, and improving construction efficiency.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
