Abstract

The invention discloses a manhole cutting auxiliary tool suitable for different round covers. The manhole cutting auxiliary tool comprises a bottom plate. The upper end of the bottom plate is providedwith a rotating base. The rotating base is internally provided with a rotating shaft. The upper end of the rotating shaft is fixedly provided with a sliding platform. The two ends of the sliding platform are provided with lead screw bases. The lead screw bases are internally provided with a bi-directional lead screw. The bi-directional lead screw is located in the sliding platform. The center ofthe bi-directional lead screw coincides with the center of the rotating base. The bi-directional lead screw is provided with two centrosymmetric sliding bases. The sliding bases are fixedly provided with upper supporting plates. The sides, facing the center of the bi-directional lead screw, of the upper supporting plates are provided with two supporting rods. The supporting rods are symmetric withrespect to the length direction of the bi-directional lead screw. The upper ends of the supporting rods are provided with positioning rods. The bottom plate is provided with an L-shaped support. Thefront end of the support is provided with a burning torch positioning hole, and the distance between the burning torch positioning hole and the center of the bi-directional lead screw is the radius ofa manhole. Compared with the traditional cutting method, the manhole cutting auxiliary tool has the beneficial effects of being high in cutting precision, the profile tolerance of the manhole is good, the following manhole cover installation error is small, and meanwhile the manhole cutting auxiliary tool is suitable for cutting operation of different sizes of water tank covers.

Description

technical field

[0001] The invention relates to the field of water tank processing, in particular to a manhole cutting auxiliary tool suitable for different round covers. Background technique

[0002] The top of the stainless steel water tank usually has a through hole that people can enter, which is convenient for workers to enter the water tank for cleaning and maintenance. The conventional method for workers to open a hole on the top cover of the water tank is to first draw the outer contour of the manhole on the top cover with a marker pen, and then use a cutting tool to The gun cuts off the manhole part along the scribed line. In order to ensure the smooth installation of the manhole cover, it is usually necessary to perform secondary grinding on the manually cut round hole so that the manhole cover can be embedded in the opened round hole. The method has low efficiency and poor precision. The present invention designs an auxiliary tooling that can not only improve the ...
