In recent years, low between conventional public transport and light rail the freight volume Rail Transit System---modern tramcar more and more comes into one's own, and the asymmetric grooved rail in cross section (referring to accompanying drawing) occurred.The characteristics of this track are to be level with road surface, therefore can share road with other vehicles, the wheel rim that its rectangle and trapezium channel section structure can effectively be protected and the guided vehicle wheel is right.The tramcar running noises is low in order to make, 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 the grooved rail push away celectome the time have 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 of interference by clamping stagnation, can't open; 2) need design to be fit to respectively the celectome that pushes away of arranged on left and right sides grooved rail, no matter make or use, all extremely inconvenient.
Summary of the invention
Primary and foremost purpose of the present invention is: for the problem of above-mentioned prior art existence, 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 the grooved rail fast, provide simultaneously corresponding operation using method.
Further aim of the present invention is: propose a kind of combined type that is fit to simultaneously 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 left cutter hub, upper knife body, the right cutter hub that is 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; In envelope after described left cutter hub, upper knife body, right cutter hub and lower knife body are crowded around, wide cross section gabarit with the grooved rail is substantially identical, 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.
Theory and practice proves, if the pin joint position that upper knife body and right cutter hub etc. are located is undesirable, and clamping stagnation while easily causing hanging cutter.Therefore optimization of the present invention is, the pin joint of described upper knife body and right cutter hub is positioned at grooved rail web of the rail center line, the horizontal line through grooved rail tread peak, the square area that the vertical extension line through the grooved rail flange of rail rightmost side surrounds.
