Middle low speed magnetic floating traffic is safe, comfortable because of having advantages of, climbing capacity is strong, noise is low, has vast potential for future development as a kind of novel urban track traffic pattern.Middle low speed magnetic floating track switch F rail movable end vertical location apparatus is an important component part of middle low speed magnetic floating track switch, and it is the device that on the track switch walking beam, the F rail docks the location with F rail on clamped beam.This device should be able to move flexibly with the track switch beam, and moving into place rear vertical degree of freedom should be limited, make movable end F rail can with fixing F rail on the buttress beam connect flat, the phenomenon of not takeofing when crossing car.With the immediate prior art of the present invention be Tangshan test wire on probation " the vertical locating connector of middle low speed magnetic floating track switch F rail movable end ", its fixed bearing directly is welded on the track switch beam, freely movable bearing is hinged on fixed bearing, about moment, degree of freedom is not limited to cause the track switch beam to move, when the moment that the track switch beam puts in place, due to motional inertia, the phenomenon of head appears getting rid of in this device excessive movement, at left and right directions with to dock line location uncontrollable.
Summary of the invention
The technical problem that the present invention solves: a kind of middle low speed magnetic floating track switch F rail movable end locating connector is provided, guarantee this device move into place with the changing points beam after vertically under the confined prerequisite of degree of freedom, its left and right degree of freedom also is limited, not only make the changing points beam rear F rail movable end that puts in place connect flat with the F rail of buttress on beam, the phenomenon of not takeofing when crossing car, and in the moment that the changing points beam moves and the moment that puts in place, swinging can not appear in F rail movable end, and can accurately dock at left and right directions.
Technical solution of the present invention: a kind of middle low speed magnetic floating track switch F rail movable end locating connector, comprise symmetrical two sections F rail movable ends, the front end of symmetrical two sections F rail movable ends will both be fixed together by the connecting cross beam that is positioned at its below, the two ends, left and right of connecting cross beam are separately installed with guide wheel assembly, and two guide wheel assemblies respectively with the buttress beam on the corresponding cooperation of two C shape grooves on inner face.The below, rear end of described symmetrical two sections F rail movable ends all is fixedly connected with movable free bearing, and described movable free bearing is made of a pair of otic placode, upper junction plate, front side board and bearing pin; Upper junction plate is fixedly connected on the upper end of a pair of otic placode and the below of F rail movable end, and front side board is fixedly connected on the below of front end and the upper junction plate of a pair of otic placode; Described a pair of otic placode is inserted into the elongated end both sides of changing points web, and by bearing pin, a pair of otic placode is hinged on the elongated end both sides of changing points web, and adjustment screw is installed on front side board, and the front end of adjustment screw is withstood on the elongated end of changing points web.
The cantilever length of described guide wheel assembly is adjustable.
The elongated end both sides of described changing points web are fixedly connected with stiffener.
The advantage that the present invention has and effect:
1, the present invention not only can satisfy the needs of the vertical location of F rail movable end, make the changing points beam put in place rear F rail movable end can with the buttress beam on the F rail connect flat, the phenomenon of not takeofing when crossing car; And can satisfy the needs of location, F rail movable end left and right, in the moment that the changing points beam moves and the moment that puts in place, swinging can not appear in F rail movable end, and can accurately dock at left and right directions.
2, positioning accuracy of the present invention is high, and the location is reliable, installs easy to adjustly, can prevent the double swerve of track switch and vertically beat during the mistake car.The Liang Junke that overhangs for the higher movable end of required precision and fixed end docking adopts this positioner.
Description of drawings
Fig. 1 is structural front view of the present invention, and Fig. 2 is structure top view of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing 1,2, a kind of embodiment of the present invention is described.
A kind of middle low speed magnetic floating track switch F rail movable end locating connector, comprise symmetrical two sections F rail movable ends 1, the front end of symmetrical two sections F rail movable ends 1 will both be fixed together by the connecting cross beam 3 that is positioned at its below, the two ends, left and right of connecting cross beam 3 are separately installed with guide wheel assembly 4, and two guide wheel assemblies 4 respectively with the buttress beam on two C shape groove 8 phase contrapositions on 7 inner faces.The below, rear end of described symmetrical two sections F rail movable ends 1 all is fixedly connected with movable free bearing 2, and described movable free bearing 2 is made of a pair of otic placode 9, upper junction plate 10, front side board 11 and bearing pin 6; Upper junction plate 10 is fixedly connected on the upper end of a pair of otic placode 9 and the below of F rail movable end 1, and front side board 11 is fixedly connected on the below of front end and the upper junction plate 10 of a pair of otic placode 9; Described a pair of otic placode 9 is inserted into the elongated end both sides of changing points web 12, and by bearing pin 6, a pair of otic placode 9 is hinged on the elongated end both sides of changing points web 12, and adjustment screw 5 is installed on front side board 11, and the front end of adjustment screw 5 is withstood on the elongated end of changing points web 12.
Can the detour elongated end of trouble turn-out track web 12 of movable free bearing 2 of the present invention rotates, and by the elevation angle of adjustment screw 5 adjustable bearings 2, and then regulates the elevation angle of guide wheel assembly 4, and guide wheel and 8 contrapositions of C type groove that guide wheel assembly 4 cantilever ends are installed are accurate.After the changing points beam swing to drive guide wheel and enters C type groove, the needs of F rail movable end 1 vertical location were satisfied in moving up and down of C type groove restriction guide wheel, prevented that track switch from vertically beating.
