Description

Light rail track beam lifting device

Technical field:

The utility model relates to a light rail track beam lifting device.

Background technique:

After the light rail line was completed and put into operation, the dedicated large-scale equipment for erecting track beams was dismantled. During light rail train operation, there is no special device to lift the track beam when the light rail track beam anchor screw needs to be replaced and maintained. Often the track beam is tied up and lifted by a crane, and then the anchor screw is taken out from the pier for replacement. Due to the heavy weight of the light rail track beam, it takes a lot of manpower and financial resources to disassemble and assemble the anchor screw. Along the light rail route, many road sections do not have enough space to use cranes for disassembly and assembly. When the anchor screw has a safety problem, it cannot be replaced in time, resulting in the non-normal operation of the light rail train and causing serious safety hazards to the light rail operation. At the same time, using a crane to lift the track beam, since there is no displacement constraint in the horizontal direction, it is easy to cause the raised track beam to shake in the horizontal direction.

Invention content:

The purpose of the utility model is to provide a light rail track beam lifting device, which is convenient for safe replacement of the track beam anchor screw.

The device includes a jack, a fixed frame, a guide frame and a pull rod. A jack is placed on each shear tenon. The front and back sides of the fixed track beams adjacent to the two ends of the lifting track beam are respectively equipped with fixed frames. The upper and lower ends of each relative fixed frame are respectively fixed on the fixed track beam through pull rods to form a clamping mechanism for the fixed track beam. A relative guide frame is fixed on the same side of each relative fixed frame, and the upper end of each relative guide frame is connected by a tie rod to form a guide slideway, and the two ends of the lifting track beam are respectively movably located in the relative guide slideway.

The purpose of this utility can be achieved through the following scheme: two opposite fixed frames are respectively placed on the front and rear sides of the fixed track beam adjacent to the two ends of the lifting track beam, and the two fixed track beams are respectively clamped by pull rods , the two opposite guide frames are fixed on the corresponding fixed frames and connected by tie rods; respectively place the two jacks on the shear tenons on the two piers at the two ends of the same raised track beam, and remove the anchor screws located on the raised beam Loosen all the nuts on the top, operate the two jacks synchronously, and make the lifted track beam slowly rise to the predetermined position by lifting the support of the track beam and then stop; after replacing the anchor screw, operate the two jacks synchronously to make the lifted track beam The beam is slowly lowered to the initial position, and finally the loosening nut is tightened to complete the safe replacement of the anchor screw of the track beam.

Technical effect of the present utility model:

1. The raised track beam is strictly restricted to move up and down in the guide slideway, which is safe to work and avoids shaking, tilting and tipping of the track beam during the lifting process.

2. The device is only composed of a jack and a small number of parts, which is convenient for transportation, easy to operate, takes up less space, has wider application occasions, and consumes less manpower and financial resources.
