AI Technical Summary
When transporting prefabricated components outdoors, the ropes of the existing lifting devices are easily affected by wind, causing the hooks to sway, which affects the stability of the prefabricated components and the safety of the lifting devices.
The design employs a combination of hydraulic cylinders, fixed plates, support rods, limit sliders, connecting components, compression springs, and anti-slip pads. The hydraulic cylinders drive the fixed plates and support rods to move downwards, while the connecting components drive the compression springs and anti-slip pads to move downwards, allowing the anti-slip pads to adhere to the surface of the precast component and provide a counterforce to fix the precast component, thus reducing hook sway.
This enabled the smooth transport of prefabricated components, reduced safety hazards associated with the lifting device, and improved the stability and safety of the lifting process.

Description
Technical Field
[0001] This utility model relates to the field of lifting device technology, specifically a lifting device for prefabricated component installation. Background Technology
[0002] Precast components are concrete building components that are manufactured before on-site construction. They are widely used in fields such as construction, transportation, and water conservancy, playing an important role in building materials. When precast components are installed and used, they need to be lifted and transported to the installation position with the help of lifting equipment. On construction sites, the installation process of precast components is generally carried out using cranes in conjunction with lifting equipment.
[0003] Existing lifting devices for prefabricated component installation use hooks and ropes to lift and transport prefabricated components to the installation location during connection and hoisting. However, when transporting prefabricated components outdoors, the ropes are easily affected by wind, causing the hooks to sway. This reduces the stability of the prefabricated components after hoisting, which in turn can affect the safety of the lifting device. Therefore, to address the above problems, we propose a lifting device for prefabricated component installation. Utility Model Content

A winding reel is fixedly connected to the outer side of the motor's main shaft. A wire rope is provided on the outer side of the winding reel. A connecting frame is fixedly connected to the lower end of the wire rope. A connecting plate is fixedly connected to the lower end of the connecting frame. A rope is fixedly connected to the lower end of the connecting plate. A hook is fixedly connected to the lower end of the rope.

A support rod is fixedly connected to the lower end of the fixing plate. A limit slider is fixedly connected to the outer side of the lower end of the support rod. An oil tank is fixedly connected to the upper end of the limit slider. A connecting pipe is fixedly connected to the lower end of the oil tank. Ball bearings are provided inside the limit slider. A connecting assembly is fixedly connected to the lower end of the fixing plate. A compression spring is fixedly connected to the lower end of the connecting assembly. A pressure plate is fixedly connected to the lower end of the compression spring. An anti-slip pad is fixedly connected to the lower end of the pressure plate. A protective shell is fixedly connected to the upper end of the tower wall.
[0007] Preferably, the motor is located inside the protective housing, the right end of the winding reel is rotatably connected to the protective housing, and one end of the wire rope passes through the tower wall.
[0008] Preferably, there are two ropes and two hooks, and the ropes are located outside the hydraulic cylinder.

[0012] In this invention, a hydraulic cylinder, a fixed plate, a support rod, a limiting slider, a connecting assembly, a compression spring, a pressure plate, and an anti-slip pad are configured. Activating the hydraulic cylinder causes the fixed plate, support rod, limiting slider, and connecting assembly to move downwards. The connecting assembly then causes the compression spring, pressure plate, and anti-slip pad to move downwards, causing the lower surface of the anti-slip pad to adhere to the upper surface of the precast component and press upwards against the compression spring. This compression spring provides a counterforce that presses down and fixes the precast component through the pressure plate and anti-slip pad. Simultaneously, the fixed plate, support rod, and limiting slider constitute a limiting device, maintaining balance between the two ropes, reducing hook sway, and allowing for stable transport of the precast component, thereby reducing safety hazards during the use of the lifting device.

The downward sliding is smoother; the support rod 11 is located on the left and right sides of the connecting assembly 16, and there are several compression springs 17. The upper end of the tower wall 1 is fixedly connected to the motor 2. The outer side of the main shaft of the motor 2 is fixedly connected to the winding reel 3.

When the hydraulic cylinder 9 is started, the hydraulic cylinder 9 drives The fixed plate 10, support rod 11, limiting slider 12, and connecting assembly 16 move downwards. The connecting assembly 16 drives the compression spring 17, pressure plate 18, and anti-slip pad 19 to move downwards, so that the lower surface of the anti-slip pad 19 fits against the upper surface of the precast component and squeezes the compression spring 17 upwards.

The motor 2 drives the winding reel 3 to rotate. The winding reel 3 pulls the wire rope 4 upward. Then, the wire rope 4 drives the connecting frame 5, connecting plate 6, rope 7, hook 8, and precast component to be lifted to a certain height. The hydraulic cylinder 9 is activated. The hydraulic cylinder 9 drives the fixed plate 10, support rod 11, limit slider 12, and connecting assembly 16 to move downward. The ball bearing 15 reduces the friction between the limit slider 12 and the rope 7 as it slides downward. The lubricating oil in the oil tank 13 flows through the connecting pipe 14 to the ball bearing 15. Lubrication is performed to make the limiting slider 12 slide downward more smoothly.
