Description

Technical Field

[0001] The present application relates to the technical field of hoisting equipment, and in particular to a hoisting alignment device for prefabricated building beams. Background Art

[0002] Precast beams are prefabricated in factories and then transported to the construction site for installation and fixation according to the design requirements. Compared with traditional cast-in-place beams, this construction method allows precast beams to be standardized in the factory, which not only improves production efficiency but also ensures the consistency of beam quality. Since the factory's production environment is relatively stable, it can better control the quality of materials and the accuracy of the process, thereby improving the overall quality of the beams. And since the beams are prefabricated in the factory, the construction site only needs to install and fix them, which greatly reduces the time and manpower investment of on-site construction. The use of precast beams can significantly shorten the construction period and improve project efficiency. After the precast beams are transported to the construction site, they need to be lifted to the required height using lifting equipment for splicing and construction. After searching, the patent document with authorization announcement number CN216785474U announced a device for aligning prefabricated building beams based on lifting, including a device main body, a lifting ring is arranged at the edge of the upper end of the device main body, a motor is arranged on one side of the lifting ring, a screw is arranged at one end of the motor, a displacement block is arranged on the outer ring surface of the screw, a fixed block is arranged at one end of the screw, a bearing is arranged on the inner side of the fixed block, a first slide groove is arranged inside the device main body, a first slider is arranged inside the first slide groove, and the displacement block can be offset by arranging the motor, the screw, the displacement block, the first slide groove and the first slider, and the first slider can be adjusted by the displacement block by cooperating with the motor and the screw, so that the load-bearing block arranged under the device main body can move laterally. In this way, the prefabricated beam can be accurately aligned by artificially controlling the device main body when the crane is not moving, thereby improving the convenience of work.

[0003] In actual use, it was found that the above scheme still has at least the following shortcomings: when the precast beam is clamped and fixed for hoisting and positioning, the position of the clamped precast beam can only be adjusted in a horizontal direction, which limits the adjustment range of the spatial position of the precast beam and cannot meet the hoisting and positioning requirements of different positions of the precast beam, affecting the work efficiency of hoisting and positioning of the precast beam.

[0004] Therefore, we propose a hoisting alignment device for prefabricated building beams to solve the above problems. Utility Model Content
