Technical Field

[0001] This invention relates to the field of construction site technology, and in particular to an intelligent fall-prevention safety hoist for construction sites. Background Technology

[0002] On construction sites such as buildings and bridges, high-altitude hoisting operations and personnel working at height are very frequent, making fall protection a core aspect of construction safety management. Traditional fall protection equipment used on construction sites is mostly a single-load structure, which generally suffers from problems such as limited functionality, insufficient connection stability, and poor flexibility in lifting and adjustment.

[0003] The traditional fall arrestor widely used in the industry today mostly adopts a single load-bearing structure design, which has obvious technical shortcomings: On the one hand, these types of fall arrestors generally rely on a single steel cable, a single hook or a simple buckle to achieve suspension and fixation, lacking multiple redundant protection and reinforcement designs. On the other hand, construction sites are often accompanied by complex working conditions such as mechanical vibration, load fluctuations, and wind interference, which can easily lead to loosening and slippage at the connection points, greatly increasing the risk of falling. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an intelligent fall-prevention safety hoist for construction sites.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: it includes a lifting device assembly, wherein lifting components are fixedly connected to the upper left and right sides of the lifting device assembly, connecting components are fixedly connected to the front and rear ends of the lifting component, and a reinforcing component is installed on the lower outer side of the connecting component.

[0006] Preferably, the lifting device assembly includes a crossbeam, with a lifting lug fixedly connected to the upper middle part of the crossbeam, and hanging devices tightly connected to both the left and right ends of the outer side of the crossbeam.

[0007] Preferably, the connecting assembly includes a fixing tube, and a steel cable is fixedly connected to one end of the fixing tube away from the lifting assembly. The steel cable wraps around the crossbeam and is arranged in a U-shape.

[0009] Preferably, the lower end of the lifting frame is fixedly connected to a connecting shaft near the left and right sides of the fixed frame, and a roller is rotatably connected to the end of the connecting shaft near the support rod, and the roller is rotatably connected to the fixed frame.

[0010] Preferably, the reinforcement component includes a retaining ring, a connecting rod is fixedly connected to the lower end of the retaining ring, a hook is installed at the end of the connecting rod away from the center of the lifting assembly, mounting holes are provided at the middle of the front end of the connecting rod and the upper side of the front end of the hook, a retaining bolt is installed at the rear end of the hook, and a nut is threadedly connected to the outer side of the retaining bolt.

[0011] Preferably, the mounting brackets are respectively installed in the middle of the lifting frame and the upper end of the fixed frame, and the fixed shaft passes through the mounting bracket and the rotating block.

[0016] Compared with existing technologies, this intelligent fall protection safety hoist for construction sites, through the setting of lifting components, reinforcement components and electric telescopic rods, the lifting components work together with the reinforcement components, the reinforcement components drive the ropes on the object to pull upward, increase the tightness, thereby improving the stability of the object at high altitudes, forming a complete fall protection system, and ensuring the safety and stability of hoisting operations at construction sites.

[0017] Compared with existing technologies, this intelligent fall protection safety hoist for construction sites uses a fixed bolt and an embedded rod. The through hole and the embedded rod work together to further tighten the fixed bolt, prevent the nut from loosening, and improve the vibration resistance and stability of the reinforcement component. After the fixed bolt is installed in place, the embedded rod passes through the through hole of the fixed bolt to limit the fixed bolt laterally, preventing it from shifting or loosening during use.

[0035] As a further implementation of the above technical solution: the fixed frame 301 provides a stable installation frame, the connecting block 302 cooperates with the support rod 303 to achieve sliding adjustment, and the lifting frame 305 is linked with the mounting frame 310 through the rotating block 309, so that the height of the lifting device can be flexibly adjusted.

[0036] Preferably, the lower end of the lifting frame 305 is fixedly connected to a connecting shaft 306 near the left and right sides of the fixed frame 301, and a roller 307 is rotatably connected to the end of the connecting shaft 306 near the support rod 303, and the roller 307 is rotatably connected to the fixed frame 301.

[0046] Preferably, the hook 403 is tightly connected to the front and rear sides with a gasket 408, and the gasket 408 is made of a silicone plate.

[0047] As a further implementation of the above technical solution: the silicone pad 408 has cushioning and anti-slip functions, reducing frictional damage between the hook 403 and the connecting parts, while enhancing the stability of the connection. The pad 408 is attached to the front and back sides of the hook 403.

[0048] Working principle:

[0049] When using this invention, during operation, the entire lifting device is first attached to the lifting equipment at the construction site via the lifting lug 102 at the upper end of the crossbeam 101 in the lifting device assembly 1. Simultaneously, the hanging brackets 103 at both ends of the crossbeam 101 are connected to the object being lifted or the protective equipment of the construction personnel, establishing the core load-bearing structure. Then, the connection and fixing procedure is initiated. The fixing pipe 201 of the connecting assembly 2 is securely connected to the lifting assembly 3. One end of the U-shaped steel cable 202 is fixed to the fixing pipe 201, and the other end is fixed to the upper end of the lifting assembly 3. Simultaneously, the fixing ring 401 of the reinforcing assembly 4 is fixed to the lower end of the connecting assembly 2. The connecting rod 402 extends to the outside, and the hook 403 is attached to the external fixing point. The fixing bolt 405 passes through the corresponding mounting hole 404 and is initially locked with the nut 409. The embedded rod 406 passes through the through hole 4 of the fixing bolt 405. 07. After the lateral limit is completed, the item is fixed to the lifting assembly 1 by ropes. The reinforcement assembly 4 is then reinstalled by ropes. During the hoisting process, if the lifting assembly 1 shakes or becomes loose, the intelligent equipment inside the crane remotely activates the lifting assembly 3. The connecting block 302 of the lifting assembly 3 slides along the corner of the fixed frame 301, driving the support rod 303 to move. The lifting frame 305 rotates around the fixed shaft 311 via the rotating block 309. The lower connecting shaft 306 drives the roller 307 to roll along the fixed frame 301 to reduce friction, thus achieving a smooth lifting of the lifting equipment to the required height. At the same time, the reinforcement assembly 4 pulls the ropes on the item upward to increase the tightness, thereby improving the stability of the item at a high altitude and forming a complete anti-fall system to ensure the safety and stability of the hoisting operation at the construction site.
