Abstract
Description
Technical Field
[0001] This utility model relates to the field of PE pipe hot-melt application technology, specifically a quick alignment clamp for PE pipe hot-melt butt welding. Background Technology
[0002] In the existing construction process of PE pipe hot-melt butt welding, the alignment of the pipes is crucial, as its accuracy directly affects the sealing performance of the joint and the overall quality of the pipe connection. However, traditional alignment methods have many problems. Relying on manual visual inspection and simple auxiliary tools for alignment makes it difficult to ensure the concentricity of the pipes, which can easily lead to misalignment. This not only reduces the strength of the joint but may also cause leakage and other hidden dangers in later use. Manual alignment is inefficient, especially in large-scale construction scenarios, consuming a lot of manpower and time. In addition, the complex construction site environment, such as space constraints and poor lighting conditions, also increases the difficulty of manual alignment. Therefore, we propose a rapid alignment clamp for PE pipe hot-melt butt welding. Utility Model Content
[0003] The purpose of this invention is to provide a quick alignment clamp for hot-melt butt welding of PE pipes to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a quick alignment fixture for hot-melt butt welding of PE pipes, comprising a shock-absorbing base plate, a lifting and adjusting structure, a processing plate, a first clamping assembly, a butt-joint limiting structure, and a second clamping assembly. The processing plate is mounted on the upper surface of the shock-absorbing base plate via three lifting and adjusting structures. The first clamping assembly is mounted on one side of the upper surface of the processing plate, and the second clamping assembly is mounted on the other side. The butt-joint limiting structure is mounted at the middle position of the upper surface of the processing plate. When the quick alignment fixture for hot-melt butt welding of PE pipes is in operation, the height of the processing plate can be adjusted according to actual operational needs via the three lifting and adjusting structures on the shock-absorbing base plate to adapt to the operator's needs in different working scenarios. To facilitate operation and meet the height requirements during pipe connection, a first clamping component on one side and a second clamping component on the other side of the upper surface of the processing plate are used to fix the two PE pipes to be connected. Through the combined action of the first and second clamping components, the pipes can be stably clamped to prevent shaking or displacement during the connection process, ensuring the stability of the connection process. The connection limiting structure located in the middle of the upper surface of the processing plate plays a key positioning role when the two pipes are connected. It can accurately limit the connection position of the pipes, so that the two pipes can be accurately connected according to the preset position during hot fusion connection, ensuring the accuracy of the connection, thereby improving the quality and efficiency of PE pipe hot fusion connection.
[0005] Preferably, the lifting adjustment structure is provided with a mounting ring, an extension rod is mounted on the mounting ring, and a tightening rod is mounted on the mounting ring. One end of the tightening rod passes through the mounting ring and is threadedly connected to the extension rod. By rotating the tightening rod, the extension length of the extension rod within the mounting ring can be adjusted, thereby realizing the height adjustment of the lifting adjustment structure. This structure is simple, easy to operate, and ensures the accuracy and stability of the lifting adjustment, making the height adjustment of the processing plate more flexible and meeting the needs of different working scenarios.
[0006] Preferably, the docking limiting structure is provided with a limiting mounting base, a limiting sleeve is installed at the middle position of the limiting mounting base, and limiting locking grooves are formed on both sides of the upper surface of the limiting mounting base. The limiting locking grooves make the docking limiting structure more convenient to install and disassemble, while enhancing the stability of the structure. The limiting sleeve plays a role in the precise positioning and guidance of the pipe, ensuring that the pipe moves along a preset path during docking, avoiding offset and misalignment, and further improving the accuracy and efficiency of docking.
[0007] Preferably, the second clamping assembly is provided with a vertical support plate, on which a first pushing assembly and a second pushing assembly are mounted, and the first and second pushing assemblies have identical structures. The first and second pushing assemblies are located on opposite sides of the vertical support plate, and through synchronous driving, both sides of the PE pipe can be clamped and pushed simultaneously, improving clamping efficiency and ensuring the stability and accuracy of the pipe during the connection process. Both the first and second pushing assemblies have adjustable pushing force to adapt to pipes of different specifications and materials, making the clamp have a wider range of applications.
[0008] Preferably, the second pushing component is equipped with a compression cylinder, and an annular compression sleeve is installed on the output end of the compression cylinder. A protective sleeve is installed on the inner side of the annular compression sleeve. The protective sleeve enhances the adaptability and protective effect of the annular compression sleeve to the pipe, and can also effectively prevent the pipe from being damaged during clamping. The compression cylinder provides a stable compression force, enabling the annular compression sleeve to fit tightly against the surface of the pipe, thereby ensuring the stability and quality of the pipe during the docking process. The combined use of the annular compression sleeve and the protective sleeve not only improves the clamping effect of the fixture, but also further expands the applicability of the fixture to pipes of different specifications.
[0009] Compared with the prior art, the beneficial effects of this utility model are:
[0010] 1. This utility model, through the combined action of the first clamping component and the second clamping component, can stably clamp the pipe, preventing the pipe from shaking or shifting during the docking process, thus ensuring the stability of the docking process. The docking limiting structure located in the middle of the upper surface of the processing plate plays a key positioning role when the two pipes are docked. It can accurately limit the docking position of the pipes, so that the two pipes can be accurately docked according to the preset position during hot fusion docking, ensuring the accuracy of the docking, thereby improving the quality and efficiency of PE pipe hot fusion docking.
[0011] 2. The protective sleeve of this utility model enhances the adaptability and protective effect of the annular pressure sleeve on the pipe, and can also effectively prevent the pipe from being damaged during clamping. The extrusion cylinder provides stable extrusion force, which enables the annular pressure sleeve to fit tightly against the surface of the pipe, thereby ensuring the stability and quality of the pipe during the docking process. The combined use of the annular pressure sleeve and the protective sleeve not only improves the clamping effect of the fixture, but also further expands the applicability of the fixture to pipes of different specifications.

The connection limiting structure 5 located in the middle of the upper surface of the processing plate 3 plays a key positioning role when the two pipes are connected. It can accurately limit the connection position of the pipes, so that the two pipes can be accurately connected according to the preset position during hot melt connection, ensuring the accuracy of the connection and thus improving the quality and efficiency of PE pipe hot melt connection.
