[0002] Stairs are common climbing and transportation facilities on construction sites and in outdoor tank environments. However, climbing stairs carries the risk of falls, especially during high-altitude work or in slippery conditions, where falls are a major safety hazard. Existing fall protection devices, such as safety belts and ropes, offer some protection but have several shortcomings, including slow response times, insufficient timeliness after a fall, limited applicability, and some devices only being suitable for specific scenarios. Therefore, there is an urgent need for a steel cable tilting fall protection device. Utility Model Content

[0008] The fixed bracket is the basic support component of the entire device. Its core function is to securely install the device on the stair handrail. The stair handrail provides a relatively fixed and easy-to-install position for the device. The fixed bracket, through its connection with the stair handrail, ensures that the device will not loosen or shift during use, providing a stable support foundation for the subsequent steel cable and braking mechanism. The steel cable is fixed to the fixed bracket and is made of high-strength material to ensure that the steel cable will not break easily. It extends along the direction of the stair handrail, allowing the steel cable to make full use of the space of the stair handrail and provide a continuous and stable sliding track for the braking mechanism.
[0009] Preferably, the triggering component includes a mechanical inertial sensor that, when a falling acceleration is detected, triggers the friction plate in the locking component to contact the steel cable for braking.
[0010] Preferably, the surface of the steel cable is provided with an anti-slip coating, and the locking assembly includes a groove structure that matches the steel cable to enhance friction during braking.
[0011] The mounting bracket includes an adjustable snap-fit structure, allowing the device to fit stair handrails of different sizes, making it highly versatile.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] This utility model provides the following technical solution:
[0022] Example 1
[0023] Please see Figure 1 , Figure 2 , Figure 3 A steel cable tilting anti-fall device includes: a fixed bracket 1 for installation on a stair handrail to provide support;
[0024] Steel cable 2, made of high-strength material, is fixed to a fixed bracket and extends along the stair handrail;
[0025] The braking mechanism 3 is slidably connected to the steel cable and includes a triggering component and a locking component.
[0026] Through the above technical solution, the fixed bracket 1 is the basic support component of the entire device. Its core function is to securely install the device on the stair handrail. The stair handrail provides a relatively fixed and easy-to-install position for the device. The fixed bracket 1, through its connection with the stair handrail, ensures that the device will not loosen or shift during use, providing a stable support foundation for the subsequent steel cable 2 and braking mechanism 3. The steel cable 2 is fixed on the fixed bracket 1 and is made of high-strength material to ensure that the steel cable will not break easily. It extends along the direction of the stair handrail, allowing the steel cable 2 to make full use of the space of the stair handrail and provide a continuous and stable sliding track for the braking mechanism 3. The braking mechanism 3 is slidably connected to the steel cable 2. The braking mechanism 3 can move freely on the steel cable 2, but at the same time is constrained by the steel cable 2 and will not detach from the steel cable 2. When a fall is detected, the braking mechanism 3 performs the braking function to prevent people from falling.
[0027] The fixed bracket 1 includes an adjustable buckle structure to adapt to stair handrails of different sizes and is fixed by bolts.
[0028] Through the above technical solution, the fixed bracket 1 includes an adjustable buckle structure, which enables the device to adapt to stair handrails of different sizes and has strong versatility. During installation, the fixed bracket 1 is firmly fixed to the stair handrail with bolts to ensure the stability of the device during use.
[0029] The triggering component includes a mechanical inertial sensor that, when a fall acceleration is detected, triggers the friction plate in the locking component to contact the steel cable for braking.
[0030] Through the above technical solution, the triggering component includes a mechanical inertial sensor. When a person falls, a certain acceleration will be generated. The mechanical inertial sensor can detect this falling acceleration and trigger the locking component to act. Under the triggering of the triggering component, the friction plate inside it will contact the steel cable 2 and prevent the braking mechanism 3 from sliding on the steel cable 2 through friction, thereby realizing the braking function.
[0031] The surface of the steel cable 2 is provided with an anti-slip coating, and the locking assembly includes a groove structure that matches the steel cable to enhance friction during braking.
[0032] Through the above technical solution, the surface of the steel cable 2 is provided with an anti-slip coating, which can increase the friction between the locking component and the steel cable. During braking, it can more effectively prevent the braking mechanism from sliding and improve the braking effect. The locking component includes a groove structure that matches the steel cable 2, which can make the friction plate and the steel cable contact more closely, increase the friction, and further enhance the braking effect.
[0033] The braking mechanism 3 also includes a reset button for manually resetting the locking component and restoring the sliding function after the brake is released.
[0034] Through the above technical solution, the braking mechanism 3 also includes a reset button. After the brake is released, the operator can manually press the reset button to restore the locking component to its initial state, release the brake on the steel cable 2, and restore the sliding function of the braking mechanism on the steel cable 2 so that the device can be used normally again.
[0035] The device also includes an auxiliary guide rail 4, which is set parallel to the steel cable 2 to guide the sliding path of the braking mechanism 3 and prevent deviation.
[0036] Through the above technical solution, the auxiliary guide rail 4 provides a stable sliding track for the braking mechanism 3, ensuring that the braking mechanism 3 can slide smoothly on the steel cable in a predetermined direction, thereby improving the stability and reliability of the device and avoiding problems such as braking failure due to deviation.
[0037] In use, the fixed bracket 1 is installed on the stair handrail to support the entire device. The braking mechanism 3 slides freely on the steel cable 2, and the auxiliary guide rail 4 ensures the stability of the sliding path. Once a person falls, the mechanical inertial sensor detects the falling acceleration and triggers the locking component to act. The friction plate contacts the steel cable, and the friction force stops the braking mechanism 3 from sliding, thereby preventing the person from falling further. After the brake is released, the locking component is reset by pressing the reset button, the braking mechanism 3 resumes its sliding function, and the device can be put into use again.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
