The threaded rod passes the ring, does not influence the rotation of threaded rod, is convenient for adjust the position of sliding seat.
Furthermore, in order to be hinged with the sliding seat, the sections of the two ends of the auxiliary hanging plate are both U-shaped.
Furthermore, in order to enable the center line of the auxiliary hanging plate to coincide with the center line of the middle hanging plate and improve the range of an included angle between the auxiliary hanging plate and the middle hanging plate, the depth value of the grooves at the two ends of the auxiliary hanging plate is 1.3-1.5 times of the length value of the strip-shaped through hole.
The utility model has the advantages that:
1. according to the scheme, the movable pulley assembly and the lifting appliance assembly are respectively matched with two ends of the steel truss girder, and the movable pulley assembly and the lifting appliance assembly are respectively matched with one truss car, so that the steel truss girder can be turned over in the air.
2. The auxiliary hanging plate is hinged with the middle hanging plate, and the steel truss girder is always in contact with the auxiliary hanging plate and the middle hanging plate in the overturning process, so that stable overturning is realized, and the generation of impact force is fundamentally avoided. The steel truss girder is turned over in the air, so that safe production and time saving can be effectively guaranteed, the occupied space is avoided, the working efficiency is greatly improved, and the economic benefit is increased.
3. The auxiliary hanging plates are connected with the middle hanging plate in a sliding mode through the sliding seats, the distance between the two auxiliary hanging plates is adjustable, the auxiliary hanging plates can be used for steel trussed beams without specifications, the number of the middle hanging plates is reduced, and production cost is reduced.
