Description

Technical Field

[0001] The present invention relates to the technical field of pipeline construction, and particularly relates to a water supply pipeline construction tool for operating without shutting off water supply. Background Art

[0002] A pipeline is a device formed by connecting pipes, pipe connectors, valves, etc. for transporting gases, liquids, or fluids with solid particles.

[0003] When new water usage demands arise and the water consumption is within the current redundancy design of the water supply pipe network. Generally, an independent water supply pipeline will not be re-laid, but instead connected to the current water supply pipe network. In existing connection methods, most often the main water pipe is first shut off, then a tee is installed on the main water pipe, and the branch pipe is installed on the tee. At this time, the main water pipe is then enabled to supply water. In this method, other water usage demands of the water supply pipe network will be affected. Summary of the Invention

[0004] To solve the above problems, the present invention discloses a water supply pipeline construction tool for operating without shutting off water supply, including a clamping fixing piece. One side wall of one clamping fixing piece is fixedly connected to a first pipe. The other end of the first pipe is fixedly connected to a second pipe. A drive motor is provided at the other end of the second pipe. One end of the drive motor extends to be provided with a motor shaft. A telescopic rod is provided below the motor shaft. An air chamber is provided inside the telescopic rod, and the motor shaft extends into the air chamber. When the drive motor operates, the motor shaft and the telescopic rod rotate. At the same time, during the rotation process, gas or liquid is injected into the air chamber, which can cause the telescopic rod to extend downward.

[0005] The lower end of the telescopic rod is fixedly connected to a cutter. The cutter is cylindrical, and serrations are provided at the lower edge. A drill bit extends in the middle of the cutter. A chamber is provided in the middle of the drill bit, and a V-shaped buckle is fitted in the chamber, and both sides of the upper part of the V-shaped buckle open outward. During the downward movement of the telescopic rod, the cutter cuts the main pipe. The pre-set drill bit first performs a drilling and positioning operation, and then the cutter cuts the main pipe. During the cutting process, the cut part of the main pipe will pass through the V-shaped buckle. Therefore, after the cutting is completed, the cut part is restricted on the drill bit and prevented from falling into the interior of the main pipe.

[0006] Preferably, a ball valve is provided in the middle of the first pipe. After the cutting is completed, the ball valve is closed, and then the second pipe can be detached from the first pipe, and a pipeline can be directly installed on the first pipe.

[0007] Preferably, a support frame is fixedly connected to the upper end of the second pipe, and the upper end of the support frame is fixedly connected to the lower end of the drive motor. This setting can expose part of the motor shaft.

[0008] Preferably, an air duct is provided in the middle of the motor shaft. The lower end of the air duct communicates with the air chamber, and the upper end of the air duct exposes from the upper side wall of the motor shaft. A rotating sleeve is rotatably fitted at this position, and an air port is provided on the side wall of the rotating sleeve. Inject gas from the air port, and the gas passes through the air duct and enters the air chamber. The provided rotating sleeve and the motor shaft are rotatably fitted, so during the rotation of the motor shaft, the gas supply will not be affected.

[0009] Preferably, a convex ring is fixedly connected to the upper side wall of the motor shaft. Guide rods are fixedly connected to the edge of the convex ring at equal angles. Guide grooves are provided on the side wall of the telescopic rod, and the guide rods are slidably fitted in the guide grooves. To prevent relative rotation between the motor shaft and the telescopic rod, guide rods and guide grooves are provided to improve the transmission strength between the motor shaft and the telescopic rod.

[0010] Preferably, several hoop rings are provided on the guide rods. To improve the stability and integrity of the guide rods and avoid the problem that the front end of the guide rod is damaged and the guide rod is separated from the guide groove.

[0011] Preferably, several overflow holes are provided at the upper end of the tool. During the cutting process, the water in the main pipe passes through the overflow holes and reaches above the tool, reducing the difficulty of the tool descending for cutting.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. Components such as clamping fixing pieces, the first pipe, and the second pipe are provided, which can perform cutting and drilling on the main pipe, and then connect the installation of the branch pipes, and reduce the impact on other water usage requirements.

[0014] 2. A V-shaped buckle is provided on the drill tool, which can limit the cut-off part on the drill tool and prevent it from falling into the main pipe and causing problems such as blockage. BRIEF DESCRIPTION OF THE DRAWINGS
