Pipe fitting clamp and minisize PP-R pipe fitting automatic connection machine using same

Abstract

The invention relates to a pipe fitting clamp and a minisize PP-R pipe fitting automatic connection machine using the same, and is characterized in that the pipe fitting clamp includes a knob rod, a toothed belt and a pressure plate which are connected together, a positioning plate and a positioning chamber which are connected together, and the pipe fitting clamp is flexible and convenient since different pipe fitting diameters can be adapted by adjusting the occlusion between an occlusal belt and the toothed belt on the pressure plate; and the minisize PP-R pipe fitting automatic connection machine includes a power device, a transmission device, a displacement device and a pipe fitting clamping device, and enables the conventional PP-R pipe fitting welding operation which relies on experiences to be changed into an automatic connection after heating, thus being suitable for various complicated working environments, greatly reducing labor intensity, and increasing labor productivity.

Description

technical field [0001] The invention relates to a pipe fitting fixture and a miniature PP-R pipe fitting automatic connecting machine using the fixture, in particular to a fixture that adapts to different pipe diameters without replacement and is suitable for different jobs when used in the welding operation of PP-R pipe fittings Automatic connection machine for miniature PP-R pipe fittings. Background technique [0002] In the practice of engineering technology, it is often necessary to fix pipes and pipe fittings. Generally, matching special fixtures are used. If the diameter of the pipe is different, the fixtures need to be replaced, which is troublesome. It is often necessary to bring multiple sets of fixtures to the site, which increases a lot of workload. For example: for on-site welding of PP-R pipe fittings, when it is necessary to weld a variety of pipes and fittings of different specifications on site, it is necessary to prepare multiple sets of fixtures, and somet...

Problems solved by technology

[0004] The large diameter of PP-R pipe generally refers to: 50mm ~ 160mm. When the pipe diameter is greater than 75mm, 2 to 3 people are required to manually operate the hot-melt connection, and when the pipe diameter is greater than 110mm and the length is greater than 10 meters (this It is a common situation for large pipe diameter welding), and it needs three people to lift it to advance. One or two people need to align the connection part, and one or two people need to lift the rear part of the pipe. Urgent need for mechanical alignment

After the connecting part is heated and carbonized by a heater, it must be connected within 10 seconds, otherwise it must be cooled and then reheated. If it is not aligned and welded, it will not meet the needs and must be sawed off and then welded again, which is time-consuming and laborious. Do not let go within 1 to 2 minutes after connecting, and let it go after it is completely cooled, otherwise it will still be deformed. Due to the large diameter and long pipe material of PP-R, the weight is heavy and the labor intensity of the workers is high.

[0005] In addition, it is more difficult to operate large diameter pipes in special workplaces: in the upper and lower floors, ceilings or in the shaft, people need to be up and down, someone shouts and pushes, and in the shaft, people are usually hung upside down, and the fusion splicer is handed to the pipe fittings. Heating requires two people outside the well to manually align the pipe fittings. Due to the small space in the well, it cannot be moved or rotated. People are in danger of being scalded by the heater. It is difficult for three people to coordinate and align them. Advance heating within 10 seconds , it is difficult to connect quickly in step, and you cannot let go within 2 minutes after connecting. The tube is heavy and easy to deform without cooling, and the labor intensity of the workers is very high.

[0006] At present, for the welding of PP-R pipe fittings with large pipe diameters, some PP-R pipe manufacturers have launched their own brand manual thermal welding machines. The heating equipment is integrated with the connecting device, and a special fixture designed by ourselves is used. Each pipe fitting size is equipped with a set. Fixtures, fixtures are frequently changed on site, and there is no universal fixture suitable for different brands; after heating, manually turn the operating lever to complete the butt joint of pipe fittings. The machine is large in size and heavy in weight. It is only suitable for very spacious and flat occasions, and cannot work at multiple angles. It is completely unsuitable for special workplaces such as corners, dead ends, shafts, ceilings, etc.

[0007] At present, there is no general-purpose miniature PP-R pipe fitting automatic connecting machine suitable for various workplaces in the welding operation of PP-R pipe fittings in the world
