Abstract
A lift device of light rail track girders refers to the rail girder lifting device solves the problem of safely changing the anchor screw of the rail girder. The utility model includes jacks, fixed frames, guiding frames, and pull rods. At the two ends of the lift rail girder, near to the front and back of the fixed rail girder, fixed frames are set face to face. The upside and underside of each fixed frame are fixed to the fixed rail girder by pull rods. The guiding frame is fixed to the same side of each fixed frame. The two ends of the lift rail girder are movably located in the guiding slide way consisted by the guiding frame and the pull rods. While working, put two jacks on cut-resistance tenons of two abutments of the two ends of the same lift rail girder respectively The device works safely, avoiding shaking, declining and turnover; the device only consists of jacks and a few parts; easy to transport, simple to use, space saving, low labor cost, low monetary cost and wider applications.
Description
Technical field:
The utility model relates to a kind of light rail rail beam lifting apparatus.
Background technology:
After the light rail circuit built up operation, the special-purpose main equipment that sets up rail beam was separated.In service at light rail train, when changeing light rail rail beam anchorage screw, needs do not have special arrangement lifting rail beam when safeguarding.Usually with this rail beam binding back utilization crane with its lifting, and then anchorage screw taken out from pier changes.Because the deadweight of light rail rail beam is bigger, the dismounting anchorage screw expends a large amount of manpower and financial resources.Along the line at the light rail route, a lot of highway sections do not have enough spaces to carry out dismounting with crane, can't in time change when safety problem appears in anchorage screw at all, cause light rail train normally not move, and operation has caused serious potential safety hazard to light rail.Simultaneously, utilization crane lifting rail beam because non-displacement constraint on the horizontal direction, causes to be lifted rail beam rocking in the horizontal direction easily.
Summary of the invention:
The purpose of this utility model is to provide a kind of light rail rail beam lifting apparatus, is convenient to safety and changes the rail beam anchorage screw.
This device comprises jack, fixed frame, guide frame, pull bar.Jack places on each shearing resistance tenon.Each is equipped with fixed frame relatively on the front and back sides of the adjacent trapped orbit beam in lifting rail beam two ends.The upper and lower end of each framework that is relatively fixed is fixed on the trapped orbit beam by pull bar respectively, constitutes the clamp mechanism of trapped orbit beam.Be fixed with relative guide frame on the homonymy of each relative fixed framework, the upper end of each relative guide frame connects and composes guide slide by pull bar, and the two ends of lifting rail beam are positioned at relative guide slide respectively versatilely.
This practical purpose can reach by following proposal: two frameworks that are relatively fixed are placed respectively on the front and back sides of the trapped orbit beam adjacent with lifting rail beam two ends, and clamping two trapped orbit beams by pull bar respectively, two relative guide frames are fixed on the respective fixation framework and by pull bar and connect; Two jack are placed respectively on the shearing resistance tenon on two piers at same lifting rail beam two ends, take down the whole nuts that loosen that are positioned on the anchorage screw that is lifted beam, two jack of simultaneously operating, the bearing by the lifting rail beam makes to be lifted and stops after rail beam slowly rises to the precalculated position; After treating anchorage screw changed, two jack of simultaneously operating again make to be lifted rail beam and slowly to drop to initial position, tighten at last and loosen nut, finish the safety of rail beam anchorage screw is changed.
Technique effect of the present utility model:
1. the rail beam that is lifted is constrained in the guide slide by strictness and moves up and down, and work safety has avoided rail beam to rock, fall partially, tumble in the lifting process.
2. this device only is made up of jack and a small amount of component, and convenient transportation is simple to operate, occupies little space, and use occasion is wider, and the manpower financial capacity of consumption still less.

The specific embodiment:
Each guide frame 20 and each fixed frame 21 are rectangle or triangle or rhombus or other polygons; Be distributed with reinforcing rib 18 in guide frame 20 and fixed frame 21, reinforcing rib 18 is horizontal or vertical or diagonal angle distribution along framework; Each guide frame 20 and each fixed frame 21 and strengthen 18 muscle and be formed by fixedly connecting with round steel or channel-section steel or i iron or angle steel fixedly connectedly comprise that welding or riveted joint or screw connect; Upper end opposite position in the framework of trapped orbit beam clamp mechanism has been fixed vertical locating piece 17, and fixed form comprises that welding or riveted joint or screw connect; Upper and lower end in trapped orbit beam clamp mechanism is processed the through hole 19 of fixedlying connected with pull bar [2,3,13,14] relatively, through hole 19 is connected by bolt 16 with the draw ring 15 at pull bar [2,3,13,14] two ends respectively, tights a bolt 16 to make fixed frame 21 firm being fixed on the trapped orbit beam [1,6]; At the through hole 19 that the processing of the upper end of each guide slide is connected with pull bar 4, through hole 19 is connected by bolt 16 with the draw ring 15 at pull bar 4 two ends, with guide frame 20 tensions; Pull bar [2,3,4,13,14] can be welded with shaped steel and two draw rings 15, also can directly use the screw rod of diameter 10～50mm to mix the nut formation.
