Embodiment

Below in conjunction with accompanying drawing the utility model is done further to describe in detail:

Consult Fig. 1 to Fig. 6, level crossing quick-clamping locating device includes level crossing 1, rubber cushion 2, clamping screw 3, set nut 4, set bolt 5, goes up angle steel 6, following angle steel 7, base 8 and hold-down nut 9.

Base 8 is welded by rectangular steel plates and rectangular steel pipe; Base 8 is placed on the smooth ground; Base 8 usefulness standard steel are processed, and the one, in order to alleviate the weight of base 8, the 2nd, can reduce machining amount; Perpendicular to six manholes of rectangular steel pipe broad one side symmetry processing, two set bolts 5 pass down two manholes of angle steel 7 respectively and two manholes of base 8 are fixedly connected with two hold-down nut 9 screw threads respectively.

Following angle steel 7 is made by angle steel; Two slotted holes of end face symmetry processing of following angle steel 7; Two manholes of side symmetry processing of following angle steel 7, clamping screw 3 passes down two slotted holes of angle steel 7 end faces from bottom to top and two manholes of last angle steel 6 bottom surfaces are fixedly connected with set nut 4 screw threads.

Last angle steel 6 is made by angle steel, two manholes of bottom surface symmetry processing of

last angle steel
