Description

Technical Field

[0001] This utility model relates to the field of high-voltage power transmission technology, specifically to a self-locking device for preventing angle steel towers from falling. Background Technology

[0002] High-voltage power transmission is a method of transmitting power by stepping up the voltage output from generators using transformers at power plants. This method is used because, for the same transmission power, the higher the voltage, the lower the current. This reduces the current during transmission, thereby reducing heat loss caused by current and lowering the material costs for long-distance transmission. Transmission towers are tower-shaped structures used for power transmission. Their structural characteristics are that all tower types are spatial truss structures, with members mainly composed of single equilateral angle steel or combined angle steel. When climbing towers, operators usually need fall arrest devices to connect them to the tower and prevent them from falling.

[0003] A self-locking device for preventing falls from angle steel towers, disclosed in Chinese Utility Model Patent Application Publication CN205252347U, is simple and robust in structure, reduces the thickness, volume, and weight of the device, and enhances its impact resistance, sealing, and reliability. It uses sensor signals to determine external environmental conditions and a controller to manage the locking and unlocking of the device. However, this self-locking device has several drawbacks. Firstly, its structural strength is low. Secondly, it cannot promptly secure personnel to the tower surface in case of a fall, resulting in low safety for personnel climbing the tower. Thirdly, it is inconvenient to disassemble and reassemble the fall protection device, thus reducing the efficiency of power transmission inspections. Utility Model Content

[0015] (III) Beneficial Effects

[0016] This utility model provides a self-locking device for preventing falls from angle steel towers, which has the following beneficial effects:

[0017] 1. This angle steel type anti-fall self-locking device for iron towers allows operators to slide the locking plate along the wire rope while climbing the tower. During this upward movement, the locking plate simultaneously engages the clamping plate with the wire rope. If the operator accidentally slips, the locking plate quickly descends along the wire rope. The downward force of the locking plate, combined with the force of the tension spring, causes the tip of the clamping plate to quickly engage with the wire rope. The clamping plate, made of high-strength alloy, rapidly compresses and fixes the wire rope, ensuring the locking plate quickly stops on the wire rope surface. This effectively prevents accidental falls and ensures the safety of operators while climbing the iron tower.

[0018] 2. This angle steel tower anti-fall self-locking device rotates the top of the positioning plate to the position corresponding to the mounting hole, allowing the positioning rod to automatically enter the mounting hole and adjust and fix the positioning plate. At the same time, personnel can move the pull plate outward and, with the cooperation of the mounting plate, move the positioning rod out of the mounting hole to unlock the positioning plate. This effectively improves the ease of disassembly and assembly of the device, making it more convenient for operators to climb and perform operations in actual use, thus achieving the goal of efficient power transmission inspection.

The device includes an installation plate 12, a stop bar 13 fixedly installed on one inner wall of the locking plate 1, a baffle 14 fixedly installed on one outer wall of the installation collar 7, and an installation rod 15 at the bottom of one outer wall of the locking plate 1. A positioning plate 16 is movably installed on the outer surface of the installation rod 15. When an operator accidentally slips, the locking plate 1 moves quickly down along the wire rope 4. Through the downward force of the locking plate 1 and the force of the tension spring 11, the tip of the clamp 9 quickly contacts the wire rope 4. The clamp 9 is made of high-strength alloy, which enables the wire rope 4 to be quickly squeezed and fixed, so that the locking plate 1 quickly stops on the surface of the wire rope 4. This effectively prevents the operator from falling and ensures the safety of the operator when climbing the tower.

[0029] In this embodiment, a connecting block 2 is provided on the inner wall of the locking plate 1, and through the cooperation of the through groove 3, it is used to lock and position the wire rope 4, allowing the locking plate 1 to slide along the wire rope 4. This allows personnel to simultaneously slide the locking plate 1 along the wire rope 4 on the tower surface when climbing the tower. During this process, an extension plate 5 is provided on the outer wall of the locking plate 1, and through the cooperation of the mounting shaft 6, it is used to support and position the mounting collar 7, allowing the mounting collar 7 to rotate and swing along the mounting shaft 6, simultaneously driving the movable plate 8 to move. A clamping plate 9 is provided on the outer wall of the movable plate 8, and an mounting sleeve plate 10 is provided on the inner wall of the connecting block 2, for supporting and positioning the tension springs 11. The bottom ends of the two tension springs 11 are connected to the mounting plate 12 on the surface of the movable plate 8. Through the force of the tension springs 11, the movable plate 8 is kept in contact with the wire rope 4. The tip of the clamping plate 9 is brought into contact with the wire rope 4. At the same time, a baffle 14 is installed on the outer wall of the mounting ring 7, and the movement angle of the movable plate 8 is positioned by the cooperation of the stop bar 13. When the operator climbs the tower, the locking plate 1 can slide up the wire rope 4. During the upward sliding process, the locking plate 1 can simultaneously bring the clamping plate 9 into close contact with the wire rope 4. When the operator accidentally slips, the locking plate 1 moves down quickly along the wire rope 4. Through the downward force of the locking plate 1 and the force of the tension spring 11, the tip of the clamping plate 9 is brought into close contact with the wire rope 4. The clamping plate 9 is made of high-strength alloy, which can quickly squeeze and fix the wire rope 4, so that the locking plate 1 can quickly stop on the surface of the wire rope 4, which can effectively prevent the operator from falling accidentally and ensure the safety of the operator when climbing the tower.

By setting a limiting plate 29 at the end of the positioning rod 28 and by the force of the positioning spring 30, the positioning rod 28 can be kept in an extended state. By rotating the top of the positioning plate 16 to the position corresponding to the mounting hole 25, the positioning rod 28 can automatically enter the mounting hole 25, thereby adjusting and fixing the positioning plate 16.
