Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated component lifting, in particular to a device for lifting prefabricated rectangular trough components with light installation and lowering. Background Art

[0002] Prefabricated rectangular trough components are large in size and heavy in weight. For safe construction, lifting equipment and hoisting devices are used to lift the prefabricated rectangular trough components, thereby moving the prefabricated rectangular trough components. When lifting and lowering the prefabricated rectangular trough components, they should be loaded and lowered gently to reduce damage to the prefabricated rectangular trough components. In order to adjust the orientation of the prefabricated components, the length of the rope is adjusted.

[0003] A Chinese utility model patent with authorization announcement number CN208814492U discloses a hoisting device for adjusting prefabricated components, comprising a fixed plate, a drive wheel, and a motor. The fixed plate has a groove-shaped cross-section, and the drive wheel is horizontally rotatably connected to the two sides of the fixed plate via a wheel axle. Two drive wheels are fixedly mounted on the same wheel axle. The motor is fixed to the fixed plate and drives the wheel axle to rotate. The hoisting rope cooperates with the drive wheel, and the rotation of the drive wheel can drive the rope to move along the rotation direction of the drive wheel. This utility model solves the problem of the time-consuming adjustment of the hoisting position of prefabricated components in the prior art. When the hoisted prefabricated component tilts, the motor is started, and the motor drives the wheel axle and the drive wheel to rotate. The drive wheel drives the rope to move along the drive wheel to adjust the length of the steel wire ropes on both sides of the hoisting device, so as to quickly adjust the prefabricated component to a relatively suitable hoisting position.

[0004] The existing light-loading and light-lowering hoisting device for prefabricated rectangular trough components is not convenient for adjusting the distance between the left and right two groups of connecting structures according to the size of the prefabricated rectangular trough component body. When adjusting the rope length, the ropes on the same side are adjusted synchronously, which is inconvenient to adjust the exposed length of the connecting ropes of each component, and thus it is inconvenient to adjust the horizontality and orientation of the prefabricated rectangular trough component body. Therefore, we propose a light-loading and light-lowering hoisting device for prefabricated rectangular trough components to solve the above-mentioned problems. Utility Model Content
