Rotary type weld beading removing knife suitable for grooved steel rail and method for hanging and fetching weld-beading removing knife

Abstract

The invention relates to the field of cutting, in particular to a rotary type weld beading removing knife suitable for a grooved steel rail and a method for hanging and fetching the weld beading removing knife. The rotary type weld beading removing knife comprises a top knife body, a left waist knife body, a right waist knife body and a bottom knife body. The left waist knife body and the right waist knife body are arranged on the left side and the right side of the top knife body respectively, the bottom knife body is located below the top knife body, installing holes are formed in the two ends of the top knife body, the left waist knife body is hinged to the top knife body through a first hinge pin, the right waist knife body is hinged to the top knife body through a second hinge pin, the first hinge pin penetrates through the installing hole in the left end of the top knife body, the second hinge pin penetrates through the installing hole in the right end of the top knife body, the left waist knife body is hinged to the bottom knife body through a third hinge pin, and a locking mechanism is arranged between the right waist knife body and the bottom knife body. The method for hanging and fetching the weld beading removing knife is based on the three hinge pins for rotating and one handle hinge pin for locking, wherein the hinge pins are arranged on the weld beading removing knife, namely the four hinge pins are utilized to hang the weld beading removing knife on the grooved steel rail and fetch the weld beading removing knife from the grooved steel rail, and the problem that an existing weld beading removing knife can not be hung on and fetched from the grooved steel rail is solved.

Description

technical field [0001] The invention relates to a cutting field, in particular to a rotary tumor pushing knife suitable for a grooved steel rail and a method for hanging and removing the knife. Background technique [0002] Grooved rails can avoid the disadvantages of traditional rails affecting the passage of other vehicles. They have the characteristics of low operating noise, strong driving stability, low vehicle operating costs, and realization of green and low-carbon transportation. They represent the future development direction of urban rail transit and have a very good market prospects. During the construction of the grooved rail line, the welding of the steel rail must be carried out. In China, pulse flash welding technology is usually used. And the weld bead that produces in the rail welding process must be removed, adopts after most of the weld bead is removed earlier with the pusher cutter after the rail welding now, adopts the method of artificial grinding the...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the phenomenon that the existing groove-shaped rail pusher knife cannot conveniently hang the knife when pushing the tumor and cannot conveniently take the knife after pushing the tumor, a rotary pusher suitable for grooved steel rails that is easy to install and disassemble is specially proposed. Tumor knife and method for hanging knife and taking knife
