Traditional safety hanging point devices often have problems such as complex installation, inconvenient adjustment, poor stability, and weak adaptability. Especially in complex and changeable working environments, these problems are particularly prominent.

[0003] At present, most safety hanging point devices on the market adopt a single clamping structure, such as simple bolt fixation or spring clamping. When dealing with fixed points of different shapes and sizes, these devices often have risks of insufficient clamping force, easy loosening or even falling off, seriously threatening the safety of operators. In addition, although some devices have adjustment functions, the adjustment process is cumbersome and the adjustment range is limited, making it difficult to meet diverse usage requirements.

[0019] As shown in the attached Figure 1 to the attached Figure 3 figures:

[0020] A safety hanging point clamp fixture provided by the present utility model includes a hanging point clamp assembly 1, a connecting rod 2, an installation limit pin 3, a hanging point slide 4, and a safety rope 5. There are two hanging point clamp assemblies 1 in total. The two hanging point clamp assemblies 1 are respectively mirror-fixed at both ends of the connecting rod 2. The installation limit pins 3 are installed at both ends of the connecting rod 2, and the installation limit pins 3 are located outside the hanging point clamp assemblies 1. The hanging point slide 4 is slidably installed on the connecting rod 2, and the safety rope 5 is fixedly connected to the hanging point slide 4.

[0021] The hanging point clamp assembly 1 includes an adjusting clamp arm 11, a wing nut 12, an upper clamping plate 13, a lower clamping plate 14, a T-shaped sleeve 15, a fixing bracket 16, a hydraulic cylinder 17, a gland 18, a fixing plate 19 and an anti-slip pad 10. The lower end of the adjusting clamp arm 11 is slid through by one end of the connecting rod 2, and the two are fixedly installed together by the wing nut 12. The adjusting clamp arm 11 is fixedly installed with the upper clamping plate 13, the lower clamping plate 14 and the T-shaped sleeve 15 through the wing nut 12. The T-shaped sleeve 15 is fixed to one end of the fixing bracket 16 through the wing nut 12. The lower clamping plate 14 fixes the hydraulic cylinder 17 through the gland 18. The output end of the hydraulic cylinder 17 passes through the gland 18 and is fixedly connected to the fixing plate 19. The anti-slip pads 10 are fixedly installed on both the fixing plate 19 and the upper clamping plate 13.

[0022] Embodiment 1:

[0023] Specifically, the adjusting clamp arm 11 is designed with a precise chute structure to adapt to and fix the upper clamping plate 13, the lower clamping plate 14 and the T-shaped sleeve 15. These chutes are opened along the length direction of the adjusting clamp arm 11. For the T-shaped sleeve 15, the upper clamping plate 13 and the lower clamping plate 14, corresponding chutes are respectively provided on the adjusting clamp arm 11, allowing these two clamping plates and the T-shaped sleeve 15 to be finely adjusted along the chutes in the vertical direction (i.e., the upper clamping plate 13 is located above the lower clamping plate 14). This design enables the clamp to tightly hold objects of different thicknesses or shapes, improving the flexibility and adaptability of clamping. Installation holes corresponding to the wing nut 12 are opened at the bottom of these chutes. The positions and sizes of these installation holes are precisely designed to ensure that the wing nut 12 can tightly fix the upper clamping plate 13, the lower clamping plate 14 and the T-shaped sleeve 15 on the adjusting clamp arm 11 through the installation holes. The wing nut 12 not only has a fastening function but also facilitates the user to quickly loosen or fasten the components by manually rotating its wing-shaped handle, improving the convenience and efficiency of operation.

[0024] Specifically, both the upper clamping plate 13 and the lower clamping plate 14 adopt a composite structure, mainly composed of a sliding cylinder, a support arm and a clamping head. This design not only improves the strength and stability of the clamping plate but also makes the adjustment and clamping functions of the clamping plate more flexible. The sliding cylinder is fixed to the chute structure on the adjusting clamp arm 11 through the wing nut 12. The use of the wing nut 12 enables the user to easily fasten or loosen the sliding cylinder by rotation, thereby adjusting the position of the upper clamping plate 13 or the lower clamping plate 14 on the adjusting clamp arm 11. The support arm is a bridge connecting the sliding cylinder and the clamping head. It provides sufficient rigidity and stability to ensure that the clamping head will not bend or deform during the clamping process. The clamping head is the part that directly contacts the target object. It is usually made of wear-resistant and corrosion-resistant materials to ensure good clamping effect during long-term use.

[0025] Specifically, the T-shaped sleeve 15 is ingeniously designed and installed below the lower clamping plate 14. This layout not only helps to disperse and balance the overall weight of the clamp assembly but also provides a stable support point for the fixing frame 16. The cross-section of the T-shaped sleeve 15 is in the shape of a "T", and this design enables it to provide stable support in the horizontal direction and allows the fixing frame 16 to be installed and fixed inside it. The fixing frame 16 fixed to the T-shaped sleeve 15 adopts an "I"-shaped structure, which has the characteristics of high strength and high rigidity and can withstand large loads without being easily deformed. One end of the fixing frame 16 is precisely inserted into the inside of the T-shaped sleeve 15 and then fastened by the butterfly fastener 12. The use of the butterfly fastener 12 makes the installation process quick and convenient. The user only needs to rotate to achieve fastening without using additional tools. In addition, several mounting holes are provided at both ends of the fixing frame 16. The existence of these mounting holes makes it possible to further expand and customize the hanging point clamp assembly.

[0026] Embodiment 2:

[0027] The upper clamping plate 13 and the lower clamping plate 14 slide in the chute of the adjusting clamp arm 11 through the sliding cylinder. After being adjusted to the appropriate position, they are fastened by the butterfly fastener 12 to achieve clamping of the upper and lower sides of the target object. The hydraulic cylinder 17 is installed below the lower clamping plate 14 and fixed by the gland 18. Its output end is connected to the fixing plate 19. When the hydraulic cylinder 17 works, it pushes the fixing plate 19 to move upward, further increasing the clamping force on the target object. The anti-slip pads 10 are installed on the fixing plate 19 and the upper clamping plate 13 to increase the friction with the target object and prevent slipping. The two hanging point clamp assemblies 1 are mirror-mounted through the connecting rod 2, and the installation limit pins 3 are used to ensure their positions on the connecting rod 2 are fixed to prevent displacement during the working process. The hanging point slider 4 slides on the connecting rod 2, can be adjusted according to needs, and provides additional safety protection for the entire fixture system through the connection with the safety rope 5. The chute design on the adjusting clamp arm 11 allows the upper clamping plate 13, the lower clamping plate 14, and the T-shaped sleeve 15 to be finely adjusted in the vertical direction to adapt to objects of different thicknesses or shapes. The combined design of the T-shaped sleeve 15 and the fixing frame 16 not only provides stable support but also makes it possible to further expand and customize the fixture system through the mounting holes on the fixing frame 16.

[0028] Using the technical solution of the present utility model, or those skilled in the art being inspired by the technical solution of the present utility model to design similar technical solutions and achieving the above technical effects shall all fall within the protection scope of the present utility model.
