Tapper for fire-fighting construction

Abstract

The invention discloses a tapper for fire-fighting construction in order to facilitate collection of cut pipe pieces and prevent an operator from being injured due to the fact that the operator picks up the pipe pieces in a pipeline. The tapper comprises a base, positioning wheels are installed below the base, a lifting structure is installed on the base, a positioning structure is installed on the lifting structure, a power structure is installed on the positioning structure, a tapping structure is installed on the power structure, the tapping structure comprises a connecting rod and a tapping cover, the tapping structure is fixedly installed on the power structure through the connecting rod, tapping cutter teeth are arranged on the tapping cover, fan blade grooves are formed in the top end of the interior of the tapping g cover. negative pressure fan blades are rotationally installed in the fan blade grooves, and four sets of air outlets are symmetrically formed in the peripheral side of the tapping cover. According to the device, pipeline suspended tapping operation is facilitated, height, angle and position positioning during tapping is facilitated, and manpower is saved.

Description

Technical field [0001] The present invention relates to the field of fire protection techniques, and is specifically a fire construction opening device. Background technique [0002] The fire opening means that the tool used on the board steel plate and the electric opening device punched on the fire water pipe. The openors are installed on ordinary electric drills, which can easily cut the circular holes, square holes, triangular holes, straight lines, and curves in any curved surface of copper, iron, stainless steel sheets or spherical surfaces. Flexible, convenient, safe and wide. Commonly used in indoor and outdoor decoration. However, the current fire construction is used for opening, and the circular material cut in the circular tube is opened by the cutting hole, and during the process, the user may be scratched by sharp cutting edges. . Moreover, when opening a hollow pipe is opened, the operation platform is first required, and then the worker stands on the operation pla...

Problems solved by technology

However, the current hole opener for fire protection construction, when the circular pipe is opened, the cut circular material will fall through the cutting hole, and the user may be scratched by the sharp cutting edge during the taking process.

Moreover, when drilling the erected suspended pipeline, it is first necessary to set up an operation platform, and then the worker stands on the operation platform to drill holes on the side of the round pipe. When drilling the side, the worker needs to move the machine to the round pipe for alignment and fixation , and then punch holes, which is not only inconvenient to operate, time-consuming and labor-intensive, but also has the danger of machine falling and hurting people

[0003] A utility model patent with the patent number CN209953846U discloses a hole opener for fire-fighting construction. Its advantage is that first magnets are installed on the left and right ends of the bottom of the partition, and the iron filings generated during cutting can be removed. Adsorbed on the surface of the magnet, it can effectively prevent iron filings from flying around during cutting, thereby reducing the risk of personnel being scratched by iron filings, and a magnet is installed at the bottom of the rotating rod, which can pass the cut iron after the cutting is completed. The piece is adsorbed on the surface of the magnet, which is convenient for the user to take out the iron piece directly after cutting, but it uses magnetism, which can only be effective for opening holes in iron round pipes, and cannot adapt to opening holes for other types of pipe fittings
