[0028] Embodiment 2

[0029] See also Figure 1-5 The connecting pipe 202 and the hole-opening drill bit 203 are provided with different models. The rear end of the hole-opening drill bit 203 is installed at the front end of the connecting shaft 6. The electric telescopic rod 301 can be controlled separately. The front end of the connecting shaft 6 is observed to the front end of the sealing joint 201. The threaded rotating rod 8 is movably connected to the inner cavity of the equipment frame 1. The surface of the threaded rotating rod 8 is meshed and connected with the movable gear box 4. The front end of the connecting pipe 202 is bolted with a closed valve 9. The front end of the closed valve 9 is bolted with a connecting sleeve 10. The inner cavity of the front end of the connecting sleeve 10 is fixedly welded with a water supply pipe 11. The contact surface between the water supply pipe 11 and the connecting sleeve 10 is provided with a sealing pad. The front and rear sides and the top of the equipment frame 1 are fixedly connected with handles 12, and the surface of the handle 12 is provided with an anti-slip rubber sleeve.

[0030] Specifically, through the connection between the threaded rotating rod 8 and the movable gear box 4, the movable gear box 4 can be made to move at a uniform speed, thereby pushing the connecting rotating shaft 6 to move. Through the setting of the closed valve 9, it can be closed after the hole opening work is completed, thereby intercepting the water and avoiding waste caused by water outflow. Through the setting of the connecting sleeve 10, the water supply pipe 11 can be wrapped and the connection can be sealed by welding to avoid leakage during use.

[0031] Working principle: The various components of the device are operated and controlled through the PLC control panel. The surface of the water pipe 11 where the hole is to be punched is cleaned, and then the connecting sleeve 10 is wrapped and sleeved on the surface of the water pipe 11. The water pipe 11 and the contact end of the connecting sleeve 10 are welded, and the closed valve 9 is installed at the output end of the connecting sleeve 10 by using bolts. The corresponding connecting pipe 202 is installed to the rear end of the closed valve 9 by using bolts, and the sealing joint 201 is installed to the rear end of the connecting pipe 202 by using bolts, thereby completing the installation of the device, and the electric telescopic rod 301 is controlled to extend and retract to drive the connecting horizontal axis 302 to move, and the movement of the connecting horizontal axis 302 drives the support base 303 to move, so that the bottom end of the support base 303 contacts the ground, and the connecting horizontal axis 302 and the support base 303 are movably connected, so that the support base 303 can fit with various terrains, thereby supporting the device, so that the device does not move during operation. The shaking and falling may cause the closed valve 9 or the connecting sleeve 10 to loosen and rotate. The closed valve 9 is opened and the servo motor 7 is controlled to work to drive the threaded rotating rod 8 to rotate. The rotation of the threaded rotating rod 8 drives the movable gear box 4 to move. The movement of the movable gear box 4 drives the connecting shaft 6 to move. The movement of the connecting shaft 6 drives the drilling drill 203 to move to the inner cavity of the closed valve 9 and the connecting sleeve 10, so that the front end of the drilling drill 203 fits the surface of the water pipe 11. Then the driving motor 5 is controlled to work to drive the connecting shaft 6 to rotate. The drilling drill 203 is driven to rotate by the rotation of the connecting shaft 6. The water pipe 11 is drilled by the rotation of the drilling drill 203 and the forward movement of the connecting shaft 6. After the drilling is completed, the rotation of the threaded rotating rod 8 drives the movable gear box 4 to move backward, so that the drilling drill 203 returns to the inner cavity of the connecting pipe 202, and the closed valve 9 is closed so that water will not flow out when the device is dismantled.
