Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of pipeline laying auxiliary tools, and relates to a PPR hot melt pipe melting automatic butt joint device. BACKGROUND

[0002] In modern construction, home decoration and various pipeline laying projects, PPR hot melt pipes have become widely used pipe materials due to their good corrosion resistance, heat preservation, hygiene and easy installation. The connection of PPR hot melt pipes mainly relies on melting butt joint technology. Through heating the connecting parts of the pipe and the pipe fitting, the melting butt joint technology makes the connecting parts melt, and then the connecting parts are quickly butt jointed and a certain pressure is applied. After cooling, a firm integrated connection is formed, which ensures the sealing and stability of the pipeline system.

[0003] At present, in many actual construction scenes, the melting butt joint of PPR hot melt pipes still generally adopts the hand-held melting butt joint mode. The above method has the following defects: On the one hand, the artificial hand-held melting butt joint has high requirements on the technical level and experience of the operator. That is, during the welding process, the heavy pipe material is easy to make the operator hold unstably, causing the pipeline butt joint to be misaligned. At the same time, the operator also needs to accurately control multiple key parameters such as hot melting temperature, heating time, butt joint pressure and angle. Any deviation in any link may lead to poor melting butt joint quality, such as unfirm butt joint at the melting butt joint or pipe diameter deformation, which seriously affects the service life and safety of the pipeline system. On the other hand, the working efficiency of hand-held melting butt joint is low. Due to the limited speed of manual operation, and the need to frequently replace the pipe material and pipe fitting during the melting butt joint process, a series of steps such as heating, butt jointing and cooling are required, which makes the overall melting butt joint progress slow, and cannot meet the construction demand of large scale and high efficiency. Especially in emergency repair engineering, the increase of time cost not only delays the construction period, but also may cause additional economic loss.

[0004] In addition, long-time hand-held melting butt joint operation is easy to make the operator tired, which further affects the quality and working efficiency of the melting butt joint. Moreover, manual operation cannot guarantee the consistency of the melting butt joint quality, which is not conducive to the overall control of the engineering quality. SUMMARY

[0005] The purpose of the present application is to solve the problems of poor butt joint quality and low butt joint working efficiency of the existing PPR hot melt pipe hand-held melting butt joint mode.

[0006] To this end, the present application adopts the following technical solutions: A PPR hot melt pipe melting automatic butt joint device, comprising symmetrically arranged clamping assemblies, and the two clamping assemblies are movably connected. The mounting assembly includes a base, with connecting rods on both sides of the base and a lower hot melt tube clamp on the top. A fixing frame is provided above the lower hot melt tube clamp, and both ends of the fixing frame are fixedly connected to the lower hot melt tube clamp. An upper hot melt tube clamp is provided below the fixing frame, and the two are movably connected by a first screw. The upper hot melt tube clamp has slots on both sides, which are engaged on the outside of the fixing frame and can move up and down along the fixing frame.

[0007] The adjacent connecting rods are movably connected by a second screw; the adjacent locking components are movably connected by a third screw; a fourth screw is provided between the adjacent locking components, and the fourth screw passes through the third screw and is connected to the connecting rod by a fixing nut.

[0008] The first, second, and third screws are all vertically arranged, while the fourth screw is horizontally arranged.

[0009] Both the lower and upper hot melt tube clamps are arc-shaped, and their curvatures are consistent; the lower and upper hot melt tube clamps are in an embracing shape.

[0010] The fixing frame is shaped like a door, with its opening facing the lower hot melt tube clamp.

[0011] The beneficial effects of this invention are as follows: During use, this invention not only helps to improve the construction efficiency of PPR hot-melt pipe fusion but also reduces construction costs, but also minimizes pipe repairs or replacements caused by fusion quality problems, avoiding adverse effects on the progress of building, home decoration and various pipe laying projects, ensuring that the entire pipe installation project can be completed efficiently and with high quality, and guaranteeing the long-term stable operation of the pipeline system.
