Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a sliding device for ensuring the lifeline of high-altitude operations. Background Technology

[0002] In high-speed, high-altitude operations (such as tower crane work, scaffolding work, bridge maintenance, and wind turbine tower maintenance), the lifeline system is the core safety guarantee for workers to prevent falls. Traditional lifeline sliding devices mostly use welded fixed guide rings or simple pulley structures, which have three major drawbacks:

[0003] Rigid connections lead to installation limitations: welded bases need to be pre-positioned on steel beams and cannot be dynamically adjusted according to the work path, resulting in high frictional resistance of the safety rope and affecting personnel movement efficiency;

[0004] Missing anti-derailment structure: Ordinary open pulleys are prone to detaching from the lifeline steel wire rope (φ8-12mm) under vibration and impact. A highway maintenance accident report showed that 19% of fall accidents were caused by the derailment of the sliding device.

[0005] Low maintenance efficiency: Existing equipment requires special tools to disassemble and replacement takes more than 15 minutes per unit, which seriously affects the progress of emergency repair operations.

[0006] Meanwhile, existing safety ropes require frequent changes to the attachment point, causing inconvenience to work and making outdoor workers unwilling to hang safety ropes. Therefore, a sliding device is provided to ensure the lifeline of high-altitude operations. Utility Model Content

[0007] To overcome the shortcomings of existing technologies, a sliding device is provided to ensure the lifeline of high-altitude operations.

[0008] This utility model is achieved through the following solution:

[0009] A sliding device for ensuring the lifeline of high-altitude operations includes an L-shaped fixed base, a U-shaped retaining ring correspondingly provided inside the fixed base, a steel wire rope correspondingly inserted into the U-shaped retaining ring, an mounting hole correspondingly provided inside the fixed base, the mounting hole being fixedly connected to a clamping bracket by bolts, and an anti-detachment ring correspondingly fitted on the steel wire rope.

[0010] The clamp holder is correspondingly installed on the outside of the fixed base.

[0011] The fixing base includes a first fixing plate and a second fixing plate. The side of the first fixing plate is perpendicularly arranged to the side of the second fixing plate. A U-shaped retaining ring is provided in the first fixing plate. The first fixing plate matches the anti-detachment ring. A mounting hole is provided in the second fixing plate.

[0012] A locking slot is provided on one side of the anti-detachment ring. The distance of the locking slot is greater than the thickness of the first fixing plate and less than the diameter of the wire rope.

[0013] The anti-detachment ring includes a fixed ring and a corresponding pull rope ring. A steel wire rope passes through the fixed ring. The fixed ring is connected to a movable block. An open lock is provided on one side of the fixed ring. The open lock passes through the fixed ring and is connected to the movable block.

[0014] The fixed ring includes an arc-shaped first ring body and a second retaining ring. The first ring body is connected to one end of the pull rope ring, and the other end of the pull rope ring is connected to the second retaining ring. The second retaining ring is movably connected to the movable block through an open lock.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model provides a sliding device for ensuring the lifeline of high-altitude operations. The device connects the safety rope through an anti-detachment ring, eliminating the need to change the position of the attachment point or disassemble the safety rope, which greatly facilitates the construction work of workers.

[0017] 2. This utility model provides a sliding device for ensuring the lifeline of high-altitude operations. The open-end lock facilitates the installation and removal of the anti-detachment ring and the wire rope. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0023] like Figure 1 and Figure 3As shown, a sliding device for ensuring the lifeline of high-altitude operations includes an L-shaped fixed base 2, with a U-shaped retaining ring 3 correspondingly provided inside the fixed base 2. A steel wire rope 1 is inserted into the U-shaped retaining ring 3. The fixed base 2 also has a corresponding mounting hole 4, which is fixedly connected to a clamping bracket 5 by bolts. An anti-detachment ring 6 is also fitted onto the steel wire rope 1. This utility model uses the anti-detachment ring 6 to significantly improve operational convenience and work efficiency. The safety rope directly passes through the pull rope ring 62 in the anti-detachment ring 6 to connect the worker. When the anti-detachment ring 6 slides along the steel wire rope 1, it can automatically cross the obstacle of the fixed base 2 and slide through the retaining ring 65 to pass over the first fixed plate 21, eliminating the need for frequent disassembly or re-suspension of the safety rope. This not only reduces maintenance time but also reduces the risk of workers abandoning the use of the safety rope due to inconvenience. In this utility model, the anti-detachment ring 6 can be made of high-strength material, maintaining impact resistance while reducing weight, and adapting to harsh outdoor environments such as strong winds or temperature changes.

[0024] The clamp holder 5 is correspondingly arranged on the outside of the fixed base 2. The external layout of the clamp holder 5 of this utility model moves the stress point to the outside of the fixed base 2, which maintains the reliability of bolt tightening and leaves a complete passage space for the wire rope 1.

[0025] The fixing base 2 includes a first fixing plate 21 and a second fixing plate 22. The sides of the first fixing plate 21 and the second fixing plate 22 are perpendicularly arranged. A U-shaped retaining ring 3 is provided in the first fixing plate 21, which matches the anti-detachment ring 6. A mounting hole 4 is provided in the second fixing plate 22. The split design of the L-shaped fixing base 2 of this utility model modularizes the function of the device. The U-shaped retaining ring 3 embedded in the first fixing plate 21 is specifically designed to support the longitudinal load of the lifeline wire rope, while the second fixing plate 22 independently bears the lateral locking force of the clamp seat 5 through the mounting hole 4. This force decomposition structure significantly reduces stress concentration, and even under high-frequency vibration conditions, the bolt connection points are not easy to loosen. At the same time, the vertical interlocking of the two fixing plates forms a stable base, avoiding the sliding path deviation of the welded base due to thermal deformation.

[0026] like Figure 1 and Figure 2 As shown, a corresponding notch 65 is provided on one side of the anti-detachment ring 6. The distance of the notch 65 is greater than the thickness of the first fixing plate 21 and less than the diameter of the wire rope 1. In this invention, the diameter of the wire rope is 8-12mm, the thickness of the first fixing plate 21 is 6mm, and the distance of the notch 65 in the anti-detachment ring 6 can be set to 7±0.3mm. The size of the notch 65 is precisely controlled to prevent the wire rope from slipping out accidentally, while allowing the device to slide freely between the fixing seats without disassembling or replacing the attachment points, which is convenient for workers working outdoors and eliminates the need to replace the attachment points of the safety rope.

[0027] The anti-detachment ring 6 includes a fixed ring 61 and a corresponding pull rope ring 62. A steel wire rope 1 passes through the fixed ring 61. The fixed ring 61 is connected to a movable block 64. An open lock 63 is provided on one side of the fixed ring 61, passing through the fixed ring 61 and connected to the movable block 64. The movable block 64 and the open lock 63 of this invention adopt a dynamic locking structure. During normal sliding, the open lock 63 tightens the movable block 64, locking the latch, preventing the steel wire rope from sliding out of the latch 65, while allowing the latch 65 to slide past the first fixed plate 21. When the anti-detachment ring 6 is hung on the steel wire rope 1, the open lock 63 is opened, and the movable block 64 rotates open, making the distance between the latches 65 greater than the diameter of the steel wire rope, facilitating the hanging of the anti-detachment ring 6 on the steel wire rope 1. Once installed, the open lock 63 is locked, keeping the movable block 64 in the closed state.

[0028] The fixing ring 61 includes an arc-shaped first ring body 611 and a second retaining ring 612. The first ring body 611 is connected to one end of the pull rope ring 62, and the other end of the pull rope ring 62 is connected to the second retaining ring 612. The second retaining ring 612 is movably connected to the movable block 64 via an open lock 63. During normal operation, the movable block 64 and the second retaining ring 612 are in a closed state to maintain the constraint of the bayonet 65. However, during disassembly, the movable block 64 can be loosened by rotating the open lock 63, and the movable block 64 and the second retaining ring 612 can be set perpendicularly to expand the gap of the bayonet 65, facilitating quick installation or removal of the anti-detachment ring 6. The movable block 64 and the second retaining ring 612 are in a locked state during normal sliding, enhancing reliability. Workers only need to pull the pull rope ring through the first fixing plate 21 to continue working.

[0029] In a specific embodiment, the wire rope 1 is laid along the tower crane or outdoor work platform, and multiple L-shaped fixing seats 2 are sequentially fixed to the outdoor equipment, allowing the wire rope 1 to cover the work area. Then, the open lock 63 in the anti-detachment ring 6 is opened, so that the movable block 64 is in a horizontal position, allowing the wire rope 1 to enter the fixing ring 61. Once installed, the open lock 63 is locked, so that the movable block 64 is in a closed position. Finally, the safety rope is passed through the rope loop 62 and tied to the worker. When working outdoors, the worker pulls the safety rope. When encountering a fixing seat 2, there is no need to disassemble the equipment; the locking clip 65 can be directly passed through the first fixing plate 21, ensuring safety while improving convenience.

[0030] Although the technical solutions of this utility model have been described and enumerated in detail, it should be understood that modifications to the above embodiments or the adoption of equivalent alternatives are obvious to those skilled in the art. Such modifications or improvements made without departing from the spirit of this utility model are all within the scope of protection claimed by this utility model.
