Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, and in particular to a PC component hoisting assembly with a weighing sensor. BACKGROUND

[0002] In the process of building industrialization, PC (precast concrete) components are increasingly widely used due to their advantages such as high efficiency and environmental protection. PC component hoisting is a key link in the construction of fabricated buildings. After being prefabricated in a factory, the components need to be transported to the construction site for installation. Hoisting operation is an important bridge connecting the factory and the construction site. Precise hoisting can ensure that the components are not damaged, improve installation efficiency and quality, and promote the rapid and orderly construction of fabricated buildings, which is of great significance to the realization of building industrialization. However, there are still some problems in current hoisting operations as follows: 1. The existing hoisting assembly ropes do not have good buffering effect. In the moment of hoisting PC component movement, the component will sway to a certain extent due to inertia, making it difficult for the component to move smoothly during transportation, reducing hoisting efficiency, and the rope sway can easily cause the component to fall off, which can seriously threaten the safety of personnel below, damage surrounding equipment, and cause major safety accidents.

[0003] 2. The clamping assembly of the existing hoisting assembly has poor stability because it can only clamp on both sides of the component. Unstable clamping can cause the component to sway, slip or even fall during hoisting. Slippage can cause the component to deviate from the predetermined position, increasing the difficulty and error of subsequent installation, reducing construction precision. In addition, when the component slips, it is difficult to discover in time, thus missing the best time for maintenance, leading to serious safety accidents. SUMMARY

[0023] As shown in Figure 3 and Figure 4As shown, the first buffer mechanism 64 includes a buffer frame 641. A first connecting block 642 is fixedly installed on the outer surface of the buffer frame 641. A first button 643 is provided on the outer surface of the first connecting block 642. The first button 643 is electrically connected to a first alarm 63, and pressing the first button 643 controls the first alarm 63 to sound an alarm. A first sliding groove 644 is formed on the outer surface of the buffer frame 641. A buffer plate 645 is provided on the lower surface of the buffer frame 641. A first sliding rod 646 is fixedly installed on the outer surface of the buffer plate 645. A first spring 647 is sleeved on the outer surface of the first sliding rod 646. A washer 648 is slidably connected to the outer surface of the first sliding rod 646. The first spring 647 is located between the buffer plate 645 and the washer 648. The washer 648 is used to prevent the washer 648 from rubbing against the inner wall of the buffer frame 641. The washer 648 and the inner wall of the buffer frame 641 are slidably connected.
