Accompanying drawing explanation
Fig. 1 is the integral structure schematic diagram (removing a positioning plate) of the utility model embodiment.
The specific embodiment
A kind of embodiment of bidirectional safety tongs of reliable operation, in Fig. 1, it installs framework is square, both sides have two side plates 3, two side plates 3 be arranged in parallel, in one end of two side plates 3, be fixedly installed end plate 2, end plate 2 has connected two side plates together, on end plate 2, be provided with pilot hole, in pilot hole, guiding is equipped with brake wheel gangbar 1, brake wheel gangbar 1 is in two parts between side plate 3 and is fixed with and lifts plate 7, lift and on plate 7, be provided with two chutes 8, two chutes 8 are in respectively the both sides of roller gangbar 1, and, the bearing of trend of two chutes 8 is all perpendicular to two side plates 3.On the madial wall of biside plate, be fixedly installed respectively and drive voussoir 5, two to drive between voussoirs 5 and corresponding side plate 3 to be provided with leaf spring 4.A side that drives voussoir 5 is with to lift plate 7 relative, and the opposite side in driving voussoir 5 on the medial surface of biside plate is respectively arranged with positioning plate 10, offers V-type chute 9 on positioning plate 10.It is V-type face that braking two drives the relative face 11 of voussoir.Between plate 7 and positioning plate 10, be provided with two friction shoes 6 lifting, the inside of friction shoe 6 is fixedly installed installation shaft 13, installation shaft 13 two ends are plugged in respectively in the V-type chute 9 of corresponding chute 8 and correspondence, and can be in chute 8 and the interior slip of V-type chute 9.
The side that friction shoe is relative with driving voussoir is also V-type face, drive the bottom of the V-type face of voussoir to convex with stable projection, stablize and on protruding end face, there is upper and lower Liang Ge inclined-plane, while moving on friction shoe, the VXing Mian bottom bearing fit of lower inclined plane and friction shoe, when friction shoe moves down, the VXing Mian top bearing fit of ramp and friction shoe, make friction shoe in the process moving up and down all the time in vertical state, can run-off the straight.
Drive the top, one end of voussoir 5 to be pressed on end plate 2, at the other end of biside plate 3, be fixed with supporting plate 12, drive on the supporting plate 12 that the other end top of voussoir 5 presses.
In brake wheel gangbar, be arranged with retracing spring 14, top, retracing spring 14 one end is pressed on end plate, and other end top is pressed on the steady ring being convexly equipped with in brake wheel gangbar 1.
Leaf spring in the present embodiment is manganese two silicon leaf springs.
Supporting plate 12 in the present embodiment is an other one end that is arranged on biside plate, can be also two, is arranged on the medial surface of side plate.
The present embodiment has stable projection, can certainly not establish, because in use, two friction shoes can grip track, can run-off the straights, and be that stressed some is inhomogeneous, only have the end contacting with the V-type face that drives voussoir stressed, easily produce distortion, but also can realize the object of clamping guide-rail.
The friction shoe of friction shoe for being formed by the manufacture of 15CRmo steel, is difficult for guide rail to cause damage, adds the setting of leaf spring, makes the effect of friction shoe and guide rail comparatively mild, is more difficult for guide rail to cause damage.
