Embodiment 1

[0025] The rotary tumor-removing knife suitable for grooved rails includes a top knife 1, a left waist knife 2, a right waist knife 3 and a bottom knife 4, and the left waist knife 2 and the right waist knife 3 are respectively arranged on the left and right sides of the top knife 1, The bottom knife 4 is located below the top knife 1, and it is characterized in that: the two ends of the top knife 1 are provided with mounting holes, the left waist knife 2 is hinged with the top knife 1 through the first pin 5, and the right waist knife 3 is connected through the second The pin shaft 6 is hinged with the top knife 1, the first pin shaft 5 passes through the mounting hole at the left end of the top knife 1, the second pin shaft 6 passes through the mounting hole at the right end of the top knife 1, and the left waist knife 2 and the bottom knife 4 A locking mechanism 8 is provided between the right waist knife 3 and the bottom knife 4 through the third pin shaft 7 being hinged. ...

Embodiment 2

[0027] The method of hanging and taking out the rotating tumor-pushing knife suitable for channel-shaped rails. Before pushing the tumor, first place the top knife 1 on the top of the channel-shaped steel rail, and the left waist knife 2 and the right waist knife 3 are respectively wound around the first pin shaft 5 , the second pin shaft 6 is screwed down, the bottom knife 4 will be screwed up through the third pin shaft 7, and then the locking mechanism 8 and the handle pin shaft 12 are used to connect each knife body into one body, so that the whole tumor pushing knife is hung on the groove On the shaped steel rail, the action of pushing the tumor knife to hang the knife is completed; after pushing the tumor, the handle pin 12 is pulled out, the locking mechanism 8 is released, the bottom knife 4 is separated from the lower part of the right waist knife 3, and the bottom knife 4 is wound around the third pin 7 Rotate away from the bottom of the grooved steel rail, the left w...

Embodiment 3

[0029] The rotary tumor-removing knife suitable for grooved rails includes a top knife 1, a left waist knife 2, a right waist knife 3 and a bottom knife 4, and the left waist knife 2 and the right waist knife 3 are respectively arranged on the left and right sides of the top knife 1, The bottom knife 4 is located below the top knife 1, and it is characterized in that: the two ends of the top knife 1 are provided with mounting holes, the left waist knife 2 is hinged with the top knife 1 through the first pin 5, and the right waist knife 3 is connected through the second The pin shaft 6 is hinged with the top knife 1, the first pin shaft 5 passes through the mounting hole at the left end of the top knife 1, the second pin shaft 6 passes through the mounting hole at the right end of the top knife 1, and the left waist knife 2 and the bottom knife 4 A locking mechanism 8 is provided between the right waist knife 3 and the bottom knife 4 through the third pin shaft 7 being hinged. ...

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...
