Description

Technical Field

[0001] The invention relates to the field of pipeline flanging tools, in particular to a flange flanging tool for thermoplastic forming and repairing a water supply pipeline. Background Art

[0002] In the water supply system, pipes often face various damage problems after long-term use, and thermoplastic molding repair technology has become an effective repair method. In the thermoplastic molding repair process, the flange flanging operation of the water supply pipe is involved, which is crucial to the connection and sealing of the repaired pipe.

[0003] The traditional flange flanging method has many limitations. In some complex water supply pipeline environments, such as when the pipeline is located in a narrow space or there are certain installation angle restrictions, traditional tools often have difficulty in accurately completing the flange flanging work. And some existing tools may not be able to adapt to water supply pipes of different diameters, and their versatility is poor. In addition, due to the special working environment of the water supply pipeline, the quality requirements for the flanging are very high. The traditional method may not be able to guarantee the flatness of the flanging and the sealing when connected with other pipe fittings. This can easily lead to problems such as leakage in the repaired pipeline during subsequent use, affecting the normal operation of the water supply system.

[0004] Furthermore, existing flanging tools are not easy to operate. Operators may need to spend a lot of physical strength and time to complete the flanging operation during use, and may need a variety of different types of tools to assist in different working conditions, which increases the complexity and cost of the repair work.

[0005] In order to solve these problems, a flange flanging tool specifically for thermoplastic forming repair of water supply pipes is needed. This tool needs to have good versatility and be able to adapt to water supply pipes of different diameters; it must be able to conveniently and accurately complete the flange flanging operation in complex environments, ensure the flanging quality, and improve the connection sealing and overall performance of the repaired pipe. At the same time, it must also focus on the convenience of operation, reduce the labor intensity of operators and improve work efficiency, so as to meet the actual needs of thermoplastic forming repair of water supply pipes.

[0006] Therefore, it is necessary to provide a flange flanging tool for thermoplastic forming and repairing water supply pipes to solve the above technical problems. Summary of the invention

[0007] In order to overcome the above-mentioned problems of low precision, poor versatility and low convenience, the present invention provides a flange flanging tool for thermoplastic forming repair of water supply pipes.

[0011] Preferably, the connecting rings 1, 2 and 3 are all provided with screw holes in the middle and ears are arranged at intervals along the circumferential direction, and the ears are provided with rotation holes.

[0013] Preferably, the uppermost end of the screw rod is threadedly connected to a handwheel, the middle portion of the screw rod is fixedly connected to a fixing nut, and the threaded portion of the screw rod below the fixing nut has opposite rotation directions.

[0014] Preferably, a connecting ring 1 is sleeved on the top of the fixing nut fixedly connected to the middle part of the screw rod, and connecting rings 2 and 3 are threadedly connected below the fixing nut fixedly connected to the middle part of the screw rod, and connecting rings 2 and 3 are respectively located at positions of different thread rotation directions below the fixing nut on the screw rod.

[0018] Through the rotational connection of the connecting rings at different positions on the screw and the upper and lower connecting rods, as well as the cooperation with the flange flanging plate and the pipe support plate, more precise flanging operation can be achieved. The rotation of the screw can accurately control the movement of each connecting rod, thereby ensuring the accuracy of the flange flanging without being excessively affected by complex working conditions such as space and angles.

[0019] Through the synergistic effect of multiple connecting rods and connecting rings, as well as the connection between the flange flanging plate and the pipe support plate through industrial hinges, the flanging process can be made more stable and uniform, thereby improving the flatness of the flanging. The pipe support plate is arc-shaped and circular after splicing. This design can not only fit the pipe well, but also the various components are connected by bolts, which makes the entire tool highly flexible during installation, adjustment and use, and facilitates rapid deployment and use in different water supply pipe repair scenarios.

The spring 9 plays a certain pushing role on the connecting ring 2 when the device is contracted, making the contraction process of the device easier and more convenient.

[0029] Among them, the upper part of the fixing nut 8 fixedly connected to the middle of the screw rod 6 is threadedly connected with a second connecting ring 11, and the upper part of the connecting ring 11 and the screw rod 6 are sleeved with a connecting ring 1 2, and the lower part of the fixing nut 8 fixedly connected to the middle of the screw rod 6 is threadedly connected with a third connecting ring 12, and the second connecting ring 11 and the third connecting ring 12 are respectively located at different positions of the thread rotation direction of the lower part of the fixing nut 8 on the screw rod 6. This design can make the second connecting ring 11 and the third connecting ring 12 move in opposite directions when the device is working, which is convenient for the expansion and contraction of the device, making the operation smoother and more efficient, reducing the labor intensity of the operator and improving the work efficiency. The first connecting ring 2 moves continuously with the rotation of the hand wheel 1, and the spring 9 plays a certain role in promoting the first connecting ring 2 when the device is contracted, making the contraction process of the device easier and more convenient. The fixing nut 8 plays the role of supporting the spring 9, and separates the first connecting ring 2 from the second connecting ring 11 and the third connecting ring 12 to prevent them from interfering with each other during the working process.

[0030] See also Figure 1-Figure 5, screw holes are provided in the middle of the connecting ring 1 2, the connecting ring 2 11, and the connecting ring 3 12, and ear pieces are arranged at intervals along the circumferential direction, and rotation holes are provided on the ear pieces to facilitate rotational connection with the connecting rod.

This arc-shaped and circular design after being spliced ​​can not only fit the pipe well, but also reflect the compactness of the structure.

[0031] During operation, the device is first placed in the pipeline, and then the screw rod 6 is rotated. Since the connecting ring 2 11 and the connecting ring 3 12 are located at positions with different thread rotation directions below the fixing nut 8 on the screw rod 6, the connecting ring 2 11 and the connecting ring 3 12 move in opposite directions. During this process, the connecting ring 2 11 and the connecting ring 3 12 respectively drive the middle connecting rod 13 and the lower connecting rod 10 to move, thereby driving the pipeline support plate 5 to move, and making the pipeline support plate 5 close to the inner wall of the pipeline to prevent damage to the pipeline during the flanging process. Then the hand wheel 1 is rotated, and the hand wheel 1 squeezes the connecting ring 1 2 to move. The connecting ring 1 2 will drive the upper connecting rod 3 to move, and then drive the flange flanging plate 4 to move, and flanging the pipeline, and the industrial hinge 7 connects the flange flanging plate 4 and the pipeline support plate 5, thereby ensuring that the flanging process is smoother. After the flanging is completed, the hand wheel 1 is rotated in the opposite direction, and the spring 9 pushes the connecting ring 1 2 to move upward to retract the flange flanging plate 4, and then the screw rod 6 is rotated in the opposite direction to shrink the pipeline support plate 5.
