PE pipe installation device for air purification system

Abstract

The invention belongs to the field of PE pipe through-wall installation, and particularly relates to a PE pipe installation device for an air purification system. The PE pipe installation device comprises an electric device, a drill bit mechanism and a guide mechanism, the bent-arc-shaped drill bit mechanism which is fixedly installed on the electric device and is in transmission connection with an electric shaft on the electric device is matched with the guide mechanism installed on a wall body or a main beam. Under the guidance of the guide mechanism, the bent-arc-shaped drill bit mechanism continues to conduct deep curve drilling on a drilled hole groove in the wall body around the circle center axis of the bent-arc-shaped drill bit mechanism to form a bent groove A so as to bypass deep reinforcing steel bars, axially meeting the hole groove, in the wall body. Then a bent groove B which is tangent to the previous bent groove A and is communicated with the bent groove A is drilled in the other side of the wall body or the main beam, so that a complete PE pipe penetrating hole is drilled, it is guaranteed that deep reinforcing steel bars, axially meeting the hole groove, in the wall body cannot be cut off by a drill bit, and then it is guaranteed that the strength of the bearing wall body or the main beam cannot be damaged.

Description

technical field [0001] The invention belongs to the field of wall-piercing installation of PE pipes, in particular to a PE pipe installation device for an air purification system. Background technique [0002] The PE pipe used as the air supply pipeline in the air purification system can be bent and wound and has a long length. During the installation of the air purification system, the PE pipe used as the air supply line needs to pass through the main beam or load-bearing wall of the house when necessary. When drilling PE pipes with water drills on the main beam or load-bearing wall, first detect the steel bars in the main beam or load-bearing wall with a metal detector, and then use the drill to drill holes at positions avoiding the steel bars. [0003] However, the thickness of the main beam or load-bearing wall is relatively large. Generally, there are three layers of steel reinforcement structures distributed in the main beam or load-bearing wall. Due to the limited de...

Problems solved by technology

[0003] However, the thickness of the main beam or load-bearing wall is relatively large. Generally, there are three layers of steel reinforcement structures distributed in the main beam or load-bearing wall. Due to the limited detection depth of metal detectors, generally only two layers on the outermost sides of the wall or main beam can be detected. Steel structure, the steel structure in the middle cannot be accurately detected and determined

This will cause the drill bit to avoid the outermost reinforcement layer of the main beam or load-bearing wall to drill holes, and it is likely to encounter the middle layer of reinforcement structure, resulting in drilling failure.

[0004] After the drilling fails, it is necessary to drill holes in different positions and seal the original hole slots. Repeated drilling will weaken the strength of the main beam or load-bearing wall and cause a certain degree of damage to the main beam or wall.
