The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, steel rail microadjuster of the present invention is symmetrical, the centre links together by horizontal connecting screw rod 11, laterally connecting screw rod 11 and the hasp 12 at two ends are for being threaded, one end is set to left hand thread, the other end is set to right-handed thread, by rotate horizontal connecting screw rod 11 can tighten up two ends base 1, make it to be fixed on concrete track plate or the concrete base; Hasp 12 is installed on the base 1 by bolt 15, and the both sides of base 1 are respectively arranged with 4 lightening holes, to alleviate the weight of whole device; Pedestal 4 is connected on the base 1 by horizontal adjustment screw rod 2, and base 1 is provided with only screw 3, deviates from base 1 when adjusting to prevent that the whole screw rod 2 of water Heibei provincial opera from rotating; Be provided with 3 rolling steel balls 8 that diameter is identical at pedestal 4 respectively with the slide plane place, both sides of base 1, as shown in Figure 4, make the relative motion between pedestal 4 and the base 1 become rolling, reduce the resistance of motion; Pedestal 4 is provided with stop screw 16, and stop screw 16 can move in the stopper slot on being arranged on base 1 17, with the distance that moves horizontally of restriction pedestal 4; Pedestal 4 is provided with rail cant and adjusts screw rod 5, and adapter sleeve 7 is adjusted rail cant screw rod 5 and just adjusted screw rod 6 and links together, and height is adjusted screw rod 6 and is arranged on the zigzag rail pawl 10, and rail pawl 10 is locked by rail pawl tie down screw 9 and rail 13.
Above-mentioned horizontal adjustment screw rod 2 is arranged to parallel with base 1 lower plane.Rail cant is adjusted screw rod 5 and is arranged to parallel with base 1 lower plane.Height is adjusted screw rod 6 and is arranged to vertical with base 1 lower plane.Horizontal adjustment screw rod 2 is parallel and vertical with the axis of just adjusting screw rod 6 respectively with the axis that rail cant is adjusted screw rod 5.Height is adjusted the bottom of screw rod 6 and preferably is arranged to bulb, and when the buffer rail base slope was adjusted screw rod 5, the bulb of adjusting screw rod 6 bottoms with height swung as fulcrum like this, and oscillation center is constant, can reduce friction, reduces wearing and tearing.For the intensity of reinforcing rail pawl, alleviate overall weight, the last plane and the lower plane shape of rail pawl 10 have a certain degree, and thicken gradually to both sides from the centre.The angle of inclination of rail pawl tie down screw 9 does not have specific (special) requirements, and its effect is fixing rail 13.
Outward flange at base 1 is provided with curved pawl 14, so that base 1 abuts against the outside of track plate, curved pawl 14 is an integrative-structure with base 1.
When carrying out rail accurate adjustment construction, the present invention is placed on the concrete track plate or concrete base of waiting to transfer the rail below, utilize the whole adjusting device of hasp 12 tensions on horizontal connecting screw rod 11 and two wing bases 1, to wait to transfer rail 13 to be placed in the rail pawl 10, and by rail pawl tie down screw 9 locking rail 13.(rail is not that vertical is installed to height, level and the rail cant that utilizes survey tools such as rail lofting instrument or track checking car to measure again to wait to transfer rail 13, two one steel rails are to tilt to the inside, this angle of inclination is exactly the rail cant angle, and this angle is generally 1: 40 definite value.) wait adjustment amount, adjust screw rod 5 by the rotation rail cant earlier then, realize the adjustment of rail 13 rail cants; Adjust screw rod 6 by the rotation height again, realize the height adjustment of rail 13 verticals; By rotation horizontal adjustment screw rod 2, realize the adjustment of rail 13 horizontal directions.
