This type of is existing push away celectome for workpiece be conventional symmetrical section I-rail.
In recent years, low freight volume Rail Transit System---modern tramcar more and more comes into one's own between conventional public transport and light rail, has occurred the asymmetric grooved rail in cross section (referring to accompanying drawing). The feature of this track is to be level with road surface, therefore can share road with other vehicles, and its rectangle and trapezium channel section structure can effectively be protected and guided vehicle is taken turns right wheel rim. In order to make, tramcar running noises is low, vehicle operating steadily, long service life etc., must be with the overlap that pushes away celectome excision track bond place welding position. Adopt the existing mentality of designing design that pushes away celectome be applicable to grooved rail push away celectome time there are two hang-ups: 1) because cutter hub need to have the projection that stretches into grooved rail rail groove down, and the reeded side of grooved rail tool is darker with respect to rail head than the degree of depth of opposite side, therefore pushing away celectome will, because interference is by clamping stagnation, cannot open; 2) need design to be applicable to respectively the celectome that pushes away of arranged on left and right sides grooved rail, no matter manufacture or use, all extremely inconvenient.
Summary of the invention
Primary and foremost purpose of the present invention is: the problem existing for above-mentioned prior art, a kind of open conveniently and simple in structure, light combined type pushes away celectome proposed, thereby needs are removed in the overlap that meets grooved rail fast, provide corresponding operation using method simultaneously.
Further aim of the present invention is: propose a kind of combined type that is simultaneously applicable to two strands of rail of a circuit and push away celectome.
In order to reach above primary and foremost purpose, combined type of the present invention pushes away celectome and comprises the left cutter hub, upper knife body, the right cutter hub that are connected according to the order of sequence, and retaining mechanism, the upper left side of described left cutter hub and upper knife body exterior feature in envelope is hinged, described retaining mechanism, by bearing pin and left cutter hub lower hinge, also comprises lower knife body; Wide substantially identical with the cross section gabarit of grooved rail in envelope after described left cutter hub, upper knife body, right cutter hub and lower knife body are crowded around, described upper knife body right part and right cutter hub top wide upper right side in envelope is hinged, and described right cutter hub bottom and lower knife body right part are hinged outside right side, wide base in envelope.
