Description
Technical Field
[0001] This utility model belongs to the field of hoisting device technology, and more specifically, it relates to a prefabricated component anti-collision hoisting device. Background Technology
[0002] Precast components refer to building parts that are prefabricated in factories or on construction sites. They usually have standardized designs, which facilitates their assembly into the main structure through transportation and hoisting. During construction, safe and efficient hoisting of precast components is one of the key aspects of their installation.
[0003] According to application number CN202421222262.8, a precast component hoisting tool includes a left base plate, a right base plate, and a bidirectional screw. A stepper motor is fixedly mounted on the left end of the bidirectional screw. A screw block is threadedly connected to the outer side of the bidirectional screw. A linkage rod is fixedly mounted on the upper side of the screw block. A guide block is fixedly mounted on the upper end of the linkage rod. An L-frame is fixedly mounted on the lower side of the screw block. An arc-shaped tube segment is arranged on the inner side of the L-frame. A counterweight block is arranged on the right side of the right base plate. A traction rope is fixedly mounted on the upper side of the left base plate. A lifting head is fixedly mounted in the middle of the traction rope. A motor fixing component is fixedly mounted on the outer side of the stepper motor. This utility model, through the coordinated use of the L-frame, stepper motor, bidirectional screw, screw block, guide block, guide rod, lifting head, and traction rope, can clamp and fix arc-shaped tube segments of different diameters. It eliminates the need for customized hoisting tools adapted to the diameter of the arc-shaped tube segments, reducing costs and improving practicality.

When the precast components collide with surrounding buildings, construction equipment, or other components, they are easily damaged, resulting in economic losses. Utility Model Content

Simultaneously, the length of the adjusting telescopic rod can be changed to accommodate components of different sizes. After inserting the hoisting plate into the lower end face of the precast component, hoisting operations begin. During hoisting, the structural design of the fixed diagonal rod and connecting hinge rod causes the hoisting hinge rod to tilt inward, thus clamping the precast component and preventing it from falling off. At the same time, the connecting sliding rod slides downward during hoisting, and drives the limiting block via the connecting cable. Moving downwards allows it to insert into the limiting slot, thus limiting the adjustment telescopic rod and improving the device's adaptability to precast components of different specifications, enhancing its practicality. The protective mechanism protects the precast components; the connecting protective rod effectively protects both sides of the component, preventing collisions due to swaying during hoisting, thereby reducing the risk of damage, minimizing economic losses, and improving construction safety. Through these mechanisms, not only is efficient hoisting of precast components achieved, but also excellent adaptability and protective performance, significantly improving the safety and economy of the construction process.
