Problems solved by technology
[0002] The track beam is an important part of the rail transit system. During the assembly process of the track beam, a spreader is usually required for hoisting. The current spreader needs to lift the track beam first, and then pass the part of the spreader under the beam. The operation is very inconvenient and there is a great potential safety hazard

The invention discloses a rail beam lifting appliance. A rail beam comprises a first side beam and a second side beam which are arranged in parallel in a spaced manner, and the first side beam and the second side beam are both provided with inner flanges extending to each other. The rail beam lifting appliance comprises a lifting plate assembly, the lifting plate assembly comprises a lifting plate, the length of the lifting plate is larger than the spacing distance between the two inner flanges, lifting lugs are arranged on the two sides of the lifting plate in the length direction, and clamped connection parts are formed by the lifting lugs and the ends, on the corresponding sides, of the lifting plate. The hanging plate assembly has an unlocking state and a locking state. When the hanging plate assembly is in the locking state, the clamped connection parts of the hanging plate assembly are suitable for cooperating with the inner flanges in a clamped connection manner. When the lifting plate assembly is in the unlocking state, the length of the projection of the lifting plate assembly on the horizontal plane is smaller than the spacing distance between the two inner flanges so that the lifting plate assembly can enter and exit from the space formed by the first side beam and the second side beam. The structure is simple, operation is simple and convenient, and safety is high.
Description
technical field [0001] The invention belongs to the field of rail transportation, and in particular relates to a rail beam spreader. Background technique [0002] The track beam is an important part of the rail transit system. During the assembly process of the track beam, a spreader is usually required for hoisting. The current spreader needs to lift the track beam first, and then pass the part of the spreader under the beam. The operation is very inconvenient and there is a great potential safety hazard. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention proposes a track beam spreader, which has a simple and compact structure, and is easy to install and disassemble, and has high safety. [0004] According to the track beam hanger of the present invention, the track beam includes first side beams and second side beams arranged in parallel and at interva...
