For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] like Figure 1-3 As shown, a high-altitude fall prevention device for an in-service iron tower with a fixed track double-sided type comprises a top plate, a bottom plate, a rack track 1, an intelligent tracking fall arrester 2, a safety rope 3 and a fall arrester transmission rope 4. The device is fixed on the iron tower through the top plate, and a rack track 1 is fixedly connected between the top plate and the bottom plate. The length of the rack track 1 is determined according to the working height of the staff. The rack track 1 is designed in a long strip shape, and inclined racks are evenly distributed vertically on the exposed surface. Electric drive wheels are respectively installed on both sides of the top plate and the bottom plate, and the electric drive wheels are controlled by a built-in self-locking motor. The fall arrester transmission rope 4 is installed on the upper and lower electric drive wheels on the same side, and the fall arrester transmission rope 4 is parallel to the rack track 1. The intelligent tracking fall arrester 2 is fixedly connected to the fall arrester transmission rope 4. One end of the safety rope 3 is fixed on the intelligent tracking fall arrester 2 and the other end is connected to the staff. The built-in self-locking motor is driven by remote control to rotate the electric drive wheel to rotate the fall arrester transmission rope 4, and the intelligent tracking fall arrester 2 rises or falls accordingly.

[0018] Specifically, the intelligent tracking fall arrester 2 includes a gravity sensor 23, a connecting piece 24, a lifting ear 25, a fixing plate 1 27 and a fixing plate 2 28. The fixing plate 1 27 and the fixing plate 2 28 are symmetrically located on both sides of the rack track 1 and are fixedly connected by the connecting piece 24. The fixing plate 1 27 and the fixing plate 2 28 are parallel to the rack track 1. The fixing plate 2 28 is fixedly connected to the fall arrester transmission rope 4. The gravity sensor 23 is installed on the fixing plate 1 27 and the fixing plate 2 28 respectively. Lifting ears 25 are installed at both ends of the fixing plate 1 27. The safety rope 3 passes through the lifting ears 25 and is connected to the staff. The fixed plate 2 28 is installed with an intelligent climbing tracking module. The intelligent climbing tracking module is connected to the gravity sensor 23 signal, and the built-in self-locking motor that controls the electric drive wheel is connected to the intelligent climbing tracking module signal.

[0019] Specifically, when the gravity value received by the gravity sensor 23 exceeds the threshold set in the intelligent climbing tracking module, and this threshold is less than the weight of the worker, the self-locking motor receives a signal to lock the electric drive wheel so that the fall arrester transmission rope 4 stops rotating, and the intelligent tracking fall arrester 2 stops lifting and lowering to prevent falling.

[0020] Specifically, the intelligent tracking fall arrester 2 also includes a pawl shaft 21, a pawl 22 and an electric pallet 26. The electric pallet 26 is installed on the fixed plate 28. The pawl shaft 21 is installed on the electric pallet 26. The lower end of the pawl shaft 21 is connected to the pawl 22. A built-in motor is installed in the electric pallet 26. The intelligent climbing tracking module is arranged in the electric pallet 26. The intelligent climbing tracking module is connected to the built-in motor signal. When the gravity value received by the gravity sensor 23 exceeds the threshold value set in the intelligent climbing tracking module, the intelligent climbing tracking module receives the signal to control the built-in motor so that the pawl 22 in the pawl shaft 21 on the electric pallet 28 extends out and engages with the rack track 1, so that the intelligent tracking fall arrester 2 is in a locked state, wherein the pawl 22 is ensured to extend long enough to avoid the pawl 22 fixed on the fall arrester transmission rope 4 from contacting the rack track 1 due to the shaking of the fall arrester transmission rope 4 in strong winds or when the staff is working.

[0021] Specifically, the connecting piece 24 is a retractable structure, so that the intelligent tracking fall arrester 2 is suitable for rack rails 1 of different thicknesses. The connecting piece 24 is made of rigid material and has a strong ability to resist deformation. When subjected to pressure or tension, it can maintain the stability and integrity of the structure and is not prone to breakage. The rack rail 1 is configured as a double-sided rack. After a single-sided rack is damaged, the position of the intelligent tracking fall arrester 2 is adjusted so that the pawl 22 can engage with the rack on the other side of the rack rail 1.

[0022] Working principle: During use, the staff first puts the safety rope 3 on their body, and at the same time starts the remote control to make the electric drive wheel drive the anti-fall device transmission rope 4 to rotate, control the rise or fall of the intelligent tracking anti-fall device 2, and realize that the intelligent tracking anti-fall device 4 changes with the height of the personnel. During the ascent, the gravity sensor 23 detects the gravity changes between the intelligent tracking anti-fall device 2 and the staff in real time. Once the gravity value detected by the gravity sensor 23 exceeds the threshold set by the intelligent climbing tracking module in the intelligent tracking anti-fall device 2, the self-locking motor built into the electric drive wheel receives the signal from the intelligent climbing tracking module to self-lock, causing the electric drive wheel to stop rotating, and the anti-fall device transmission rope 4 also stops rotating. At the same time, the electric card plate 26 receives the signal from the intelligent climbing tracking module to cause the ratchet 22 in the ratchet shaft 21 to extend and engage with the rack track 1, thereby locking the intelligent tracking anti-fall device 2.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
