Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline construction, and in particular relates to a PE pipeline hot-melt connection auxiliary device. Background Art

[0002] PE pipes are made of polyethylene (PE) and have a wide range of applications and diverse properties. They offer numerous advantages, including excellent temperature resistance: PE pipes can be used in temperatures ranging from -75°C to 40°C, with a very low brittle temperature, making them suitable for winter installation and construction. They also exhibit strong corrosion resistance: Polyethylene is an inert material, resistant to a wide range of chemical media, requiring no corrosion protection and immune to rot, rust, and corrosion. They also exhibit excellent flexibility: With an elongation at break exceeding 800%, local vibrations will not cause vibrations throughout the pipe, resulting in strong shock resistance.

[0003] In existing technology, hot-melt connection is primarily used to connect PE pipes. This involves placing the mating surfaces of two PE pipes against a heating tool and heating them until their flat ends fuse. After removing the heating tool, the two fused ends are pressed together and held under pressure until the joint cools. Once cooled, the two pipe sections are joined into a single piece. Hot-melt connection is a reliable and efficient method for connecting PE pipes, widely used in water supply, drainage, gas, and other fields.

[0004] The main disadvantage of the hot melt connection method is that it has high operating requirements for workers, and improper operation can easily lead to a decline in the quality of the connection. Utility Model Content

[0005] The purpose of this utility model is to address the above-mentioned problems in the existing technology and propose a PE pipe hot-melt connection auxiliary device, which can improve the automation level of PE pipe hot-melt connection, make it more convenient to connect two PE pipes, reduce the intensity of manual operation, and improve the accuracy of hot-melt connection.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows:

[0007] A PE pipe hot-melt connection auxiliary device includes a base, a movable mechanism arranged on the base, and a fixed mechanism arranged on the base; the movable mechanism includes a driving cylinder, a sliding rail, and two pipe placement brackets arranged on the base; the pipe placement bracket includes a movable support, a pipe locking strip arranged on the movable support, and the movable support is slidably connected to the sliding rail through a slider, and the slider of the outer pipe placement bracket is connected to the piston rod of the driving cylinder, and a plurality of linkage rods are connected between the two movable supports.

[0008] Furthermore, the fixing mechanism includes a plurality of pipe placement racks and a hot melt placement rack arranged in the middle of the base.

[0009] Furthermore, the hot melt placement rack includes a support column fixed on the base, an arc-shaped support plate arranged on the support column, and a hot melt placement groove is arranged on the arc-shaped support plate.

[0010] Furthermore, the arc-shaped support plate is provided with pipeline placement steps on both sides of the heat fuser placement groove.

[0011] Furthermore, each of the pipeline placement racks includes a mounting support fixed on the base, and a pipeline locking strip arranged on the mounting support.

[0012] Furthermore, a plurality of lifting armrests are provided on the base.

[0013] Compared with existing technologies, the advantages of this utility model are as follows: First, by integrating a movable part and a fixed part on a single base, the movable part's reciprocating motion controls the movement of the two pipes to be hot-melted, reducing manual labor intensity. Second, the mechanical alignment of the pipes avoids problems such as uneven manual alignment during the hot-melt process. Furthermore, the cylinder can be used to control the extrusion and alignment of the pipes after heating, improving the hot-melt connection effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0024] like Figure 1As shown, the PE pipe hot-melt connection auxiliary device includes a base 1, a movable mechanism arranged on the base 1, and a fixed mechanism arranged on the base 1; the movable mechanism includes a driving cylinder 7, a sliding rail 8, and two pipe placement brackets 2 arranged on the base 1; the pipe placement bracket 2 includes a movable support, a pipe locking strip 5 arranged on the movable support, and the movable support is slidably connected in the sliding rail 8 through a slider, and the slider of the outer pipe placement bracket 2 is connected to the piston rod of the driving cylinder 7, and a plurality of linkage rods 6 are connected between the two movable supports.

[0025] Compared with the prior art, in the prior art, the connection of PE pipes is mainly achieved by hot-melt connection, and the general technical means include manual hand-held operation, manual clamping and hot-melt welding based on the workers' technical experience. In order to address the labor intensity of manual operation, some hot-melt welding machines have also appeared on the market. However, these hot-melt welding machines are either complex in structure or have few connecting parts for PE pipes, which leads to the PE pipe being easily warped due to the weight of the pipe during butt welding, resulting in uneven connection at the butt joint. In the present invention, a movable part and a fixed part are respectively integrated on the base 1, and multiple brackets for placing pipes are respectively provided on the movable part and the fixed part. The linkage rod 6 between the two movable supports can be replaced according to the length of the PE pipe to be welded, thereby adjusting the distance between the two movable support brackets, so that the two movable supports can distribute the force more evenly, avoiding the occurrence of pipe warping during the later butt joint. At the same time, the present invention improves work efficiency and reduces manual labor intensity through automated operation.

[0026] The fixing mechanism includes a plurality of pipe placement racks 3 and a hot melt placement rack 4 arranged in the middle of the base 1. The hot melt placement rack 4 includes a support column fixed to the base 1, an arc-shaped support plate arranged on the support column, and a hot melt placement groove 9 is provided on the arc-shaped support plate. Simple fixation is achieved by directly placing the hot melt in the groove, and the arc-shaped support plate is provided with pipe placement steps on both sides of the hot melt placement groove 9. By connecting the docking sections of the PE pipe to the placement steps respectively and moving them closer to the hot melt placement groove 9, after heating and removing the hot melt, the docking can be completed and wait for cooling.

[0027] Each of the pipeline placement racks 3 includes a mounting support fixed on the base 1 and a pipeline locking strip 5 arranged on the mounting support.

[0028] The base 1 is provided with a plurality of lifting handrails 10. The auxiliary device can be quickly carried by the lifting handrails.

[0029] During specific use, the auxiliary device provided by the utility model is pulled to the construction site, and hot melt welding construction is carried out according to on-site requirements. By adding the form of clamping tiles, PE pipes of various diameters to be hot-melted are adapted, and the PE pipes to be hot-melted are locked by the locking strip 5. One end of the two PE pipes to be hot-melted is placed on the hot melt placement rack 4, and the end faces of the two PE pipes are smoothed with a milling cutter. Then, the hot melt is placed in the hot melt placement groove 9, and the cylinder is used to push the movable mechanism to move and allow the two PE pipes to clamp the hot melt. After heating is completed, the cylinder is recovered and the hot melt is taken out, and the cylinder is used again to push the two PE pipes to tighten until the end faces of the two PE pipes cool and solidify.

[0030] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
