Description

Technical Field

[0001] This utility model relates to the field of high-altitude protection, and in particular to a safety protection device for high-altitude installation of steel structure bridges. Background Technology

[0002] 1. Fall from a height Falls from height are a common safety risk in bridge construction, especially when working at heights. During the construction of steel structure bridges, workers often need to work at heights, such as on the bridge deck and piers. Due to inadequate protective measures, improper operation, or unexpected factors, workers may fall from heights, causing serious personal injury or even death.

[0003] 2. Scaffolding collapse Scaffold falls are another major risk in working at heights. The main risks include stepping on protruding scaffold boards, missing a step, tripping, falling, scaffold boards not being fully laid or being laid unstable, lack of guardrails or damaged guardrails, lack of a safety protection layer below the working level, and scaffolds being more than 20 centimeters away from the wall without any protective measures.

[0004] 3. Falls from heights while working suspended in mid-air The risk of falling while working at height mainly comes from factors such as a narrow foothold, excessive force leading to instability, center of gravity exceeding the foothold, slipping or accidentally stepping into a hole, not wearing a safety belt or not using it correctly, a safety belt hook not being secure, lack of safety ropes on site, and lack of safety nets at the work site.

[0005] 4. Falling during demolition work When dismantling certain parts of a steel bridge structure, such as scaffolding, hoisting frames, or gantry cranes, failure to take appropriate safety measures, such as not wearing safety belts or not setting up temporary wire mesh before dismantling scaffolding, may also lead to falls.

[0006] 5. Falling during ascent The absence of safe climbing facilities, the malfunction or damage of climbing facilities, the failure to conduct regular safety inspections of climbing facilities, and actions such as climbing scaffolding, well derricks, gantry cranes, or riding non-passenger transport equipment can all lead to falls during the climbing process.

[0007] Preventive measures To effectively control these fall risks, the following preventative measures can be taken: Identify the risk points of high-altitude operations and prioritize measures for safety management.

[0008] Provide professional training to those in charge of high-altitude operations and on-site management personnel so that they can master the safety regulations and preventive measures for high-altitude operations.

[0009] During high-altitude operations, workers must wear necessary protective equipment, such as safety helmets, protective shoes, and safety ropes. At the same time, the construction site should be equipped with various safety protection equipment, such as safety nets and safety ladders.

[0010] When designing and manufacturing aerial hoisting equipment, various safety factors should be considered, and corresponding safety management regulations should be formulated according to actual needs. Regular inspections and maintenance of the hoisting equipment should be carried out.

[0011] The above measures can effectively reduce the risk of falls during high-altitude operations on steel structure bridges and protect the lives of workers.

[0012] On June 3, 2025, a search was conducted in the China Patent Publication Database using "high altitude and fall and clamping and teeth and safety rope" as the full-text keywords, with the option to allow synonym expansion. No relevant literature was found.

[0013] It is completely different from the concept of this patent.

[0014] The drawbacks of these technologies are that their structures are too complex, they cannot be clamped quickly, and their costs are too high. Utility Model Content

[0015] The purpose of this utility model is to provide a more effective safety protection device for high-altitude installation of steel structure bridges. The specific purpose is explained in the detailed implementation section for several substantial technical effects.

The rope clamping position 1 includes a clamping base plate 41 that is integrated or fixed to the vertical rod 2, and also includes a clamping outer plate 42. The clamping base plate 41 and the clamping outer plate 42 can be clamped together by clamping bolts. There are clamping teeth 43 between the clamping base plate 41 and the clamping outer plate 42, and the clamping teeth 43 can clamp the rope.

[0017] A further technical solution of this utility model is that the clamping teeth 43 are located on the clamping base plate 41 and / or the clamping outer plate 42.

[0018] A further technical solution of this utility model is that the clamping teeth 43 are located at the protruding position of the clamping base plate 41, and the clamping outer plate 42 includes a groove for corresponding to the clamping teeth 43.

[0019] A further technical solution of this utility model is that the clamping base plate 41 and the clamping outer plate 42 can be fixed together by clamping bolts passing through the clamping bolt holes 5 to provide pressure and thus tighten the rope head.

[0020] A further technical solution of this utility model is that the clamping gap 33 can clamp the top wall.

[0021] A further technical solution of this utility model is that the clamping teeth 43 are arranged horizontally or vertically.

[0022] A further technical solution of this utility model is that the bottom fixing part 3, the vertical rod 2, and the rope clamping position 1 are all made of high-strength steel.

[0023] The present invention, which adopts the above technical solution, has the following beneficial effects compared with the prior art: it is used for protection during on-site installation and welding of bridges, and plays a role in being simple in structure, convenient in operation, economical, practical and efficient in use.

[0024] To achieve good welding results, the paint, dirt, and oxide layer of the weld layer must be cleaned before welding to prevent impurities from decomposing due to heat during welding.

[0025] The main function of installing welding guardrails on bridges is safety protection. They can prevent accidents during on-site welding and warn workers to pay attention to the impact of the on-site environment on the operation. If personnel safety or other hazards are endangered, workers can be evacuated from the dangerous environment in a timely manner.

[0026] It can prevent minor accidents and has advantages such as good impact resistance, low cost, long life, higher safety, and green environmental protection. Attached Figure Description
