Description
Technical Field
[0001] The utility model relates to the technical field of crossbeam hoisting, in particular to a crossbeam hoisting and fixing mechanism. Background Art
[0002] A crossbeam is a horizontal beam, which is generally perpendicular to the longitudinal beam and distributed along the short axis of the building. The crossbeam and the longitudinal beam jointly support the top surface of the building. The installation of crossbeams is generally carried out by hoisting. In order to ensure the safety of the crossbeam hoisting operation, a special crossbeam lifting and fixing mechanism is required to lift the crossbeam.
[0003] The connecting and fixing hooks of the existing beam lifting and fixing mechanisms are usually in an inclined hook state, which can easily cause the user to get stuck on the edge of the beam when removing the beam when the crane is not lowered far enough, making it inconvenient to remove the beam, thereby wasting a lot of work time. In addition, the universal performance is poor and the mechanism can only be used for lifting and fixing beams of a single specification. Utility Model Content
[0004] The present invention relates to a crossbeam lifting and fixing mechanism, which solves the problem that the connection and fixing hook of the existing crossbeam lifting and fixing mechanism is usually in a tilted hook state, which makes it easy for the user to get stuck on the edge of the crossbeam when removing the crossbeam when the crane is not lowered far enough, making it inconvenient to remove the crossbeam, thereby wasting a lot of working time, and has poor universal performance and can only be used for lifting and fixing crossbeams of a single specification.

[0010] Furthermore, two movable holes are provided at the bottom of the fixed hook, the movable holes are connected to the movable grooves, a limiting movable column is provided inside the hook block, and the end of the limiting movable column moves in the movable hole provided in the fixed hook.
[0011] Furthermore, the spring is located in the movable hole, the bottom end of the spring is welded to the bottom of the movable hole, the top end of the spring is welded to the end of the limiting movable column, and the fixed hook is driven upward by the crane. When the beam contacts the hook-shaped part at the bottom of the fixed hook, the inner end of the hook block is squeezed and rotated by the beam, so that the inner end of the hook block is horizontal and the outer end of the hook block is tilted. The spring contracts and accumulates force due to the squeezing, and the tilted outer end of the hook block stabilizes the beam to prevent the beam from falling off from the hook-shaped part at the bottom of the fixed hook.

[0014] In addition, the fixed hook is driven upward by the crane, and when the cross beam contacts the hook-shaped part at the bottom of the fixed hook, the inner end of the hook block is squeezed and rotated by the cross beam, so that the inner end of the hook block is horizontal and the outer end of the hook block is tilted. The spring contracts and accumulates force due to the squeezing, and the tilted outer end of the hook block stabilizes the cross beam to prevent the cross beam from falling off from the hook-shaped part at the bottom of the fixed hook. When the cross beam is placed at the designated position, the crane drives the fixed hook to move downward, and the inner end of the hook block is rotated and reset by the thrust of the spring, so that the inner end of the hook block is tilted and the outer end of the hook block is horizontal. The user can more easily separate the fixed hook from under the cross beam. By adding a hook block that can be tilted, horizontal, and automatically reset, the user can more conveniently take out the fixed hook when removing the cross beam, which effectively improves the work efficiency of the staff and can reduce the amplitude of the crane lowering.
