Description

Technical Field

[0001] The utility model relates to the technical field of polyethylene pipe hole opening devices, in particular to a hole opening device for fixed spacing. Background Art

[0002] Polyethylene pipe is a water supply pipe made of polyethylene resin as the main raw material and formed by extrusion. It is suitable for indoor and outdoor low-temperature water supply pipelines, etc. Polyethylene pipe processing refers to the process of making polyethylene pipe by extrusion molding with polyethylene resin as the main raw material, adding a certain amount of heat stabilizer, colorant and processing aid. In the secondary processing of pipes, especially in the process of on-site installation, it is sometimes necessary to open holes in the pipes through a hole-opening device.

[0003] The existing hole-opening device generally includes a base, with a sleeve made on both sides of the base, and a lifting screw is installed in each sleeve. A lifting plate is jointly mounted on the outer sides of the two screws, and a motor is installed above the lifting plate. A cutter head is installed on the output end of the motor, and a chain is installed below the base. When in use, the entire hole-opening device is mounted on the outer periphery of the pipe for fixation through the chain, and then the cutter head is controlled to move down to open a hole. After the hole-opening device has opened a hole once, if a second hole is to be opened at other positions of the pipe, the chain is loosened. After the hole-opening device is removed, it is moved to the next hole-opening position and the chain is installed again for the second hole-opening. However, during the disassembly and reinstallation process, it is difficult to ensure that the hole-opening device only changes position along the axial direction, which can easily cause the position of the two holes to shift. In addition, if more than two through holes need to be opened in a pipe, other measuring tools are required to measure the distance between two adjacent through holes, which is very inconvenient to operate. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that after a hole-opening device has opened a hole once, if a second hole is needed to be opened at other positions of a pipe, the chain is loosened, and after the hole-opening device is removed, it is moved to the next hole-opening position and the chain is installed again for the second hole-opening. However, during the disassembly and reinstallation process, it is difficult to ensure that the hole-opening device changes position only along the axial direction, which can easily cause the positions of the two holes to shift. In addition, if more than two through holes are needed to be opened in a pipe, other measuring tools are required to cooperate in measuring the spacing between two adjacent through holes, which is very inconvenient to operate. Therefore, a hole-opening device for fixed spacing is proposed.
