Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a hookless safety rope guidance system and its construction method. Background Technology

[0002] In the construction industry, working at heights is a widespread and crucial aspect. According to the national standard GB / T3608-2008 "Classification of Working at Heights," any work performed at a height of 2 meters or more above the reference plane where there is a possibility of falling is considered working at heights. Due to the unique nature of working at heights, there are numerous safety hazards, and falls from heights are among the most common safety accidents in the construction industry.

[0003] In the process of investigating and analyzing a series of falls from heights, in addition to the workers' weak safety awareness and low level of construction management, the most prominent cause of the accidents was that the installation of safety belts restricted the workers' range of movement (the range of movement of conventional safety belts is within 2 meters), which led to the phenomenon that workers would only wear safety belts but not fasten them during actual high-altitude operations. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a hookless safety rope guiding system and its construction method, which avoids the pain point of having to constantly hook the safety rope. It can meet the needs of workers' range of movement on the work surface and effectively reduce the probability of falls from heights.

[0005] To achieve the above objectives, the present invention provides a hookless safety rope guiding system, wherein the safety belt buckle can be freely slidably attached to the safety rope. The guiding system includes at least two guiding devices, and the number and arrangement of all guiding devices are such that, with each guiding device serving as a buckle fixing point, it can cover any working position within the safety rope knot range; wherein, the guiding device includes:

[0006] Fixtures are used to securely connect to components at the work location;

[0007] An impeller is rotatably mounted on the fixture via a shaft, and a notch is formed between each pair of adjacent blades on the impeller to accommodate the snap fastener;

[0008] Two limiting members are fixedly installed on the fixing device and located on both sides of the impeller along the extension direction of the safety rope. Both limiting members are located above the rotating shaft and extend towards the side of the fixing device opposite to the component, so as to form a passage for the safety rope to pass through between them and the rotating shaft.

[0009] The impeller can switch between a first state where the buckle is locked at the current buckle fixing point and a second state where the buckle is allowed to slide to the next buckle fixing point by rotating. In the locked state, the buckle is locked in a notch at the current buckle fixing point. In the sliding state, the buckle disengages from the notch and moves to the next buckle fixing point.

[0010] Preferably, the impeller includes two impeller bodies coaxially fixedly connected to both ends of the rotating shaft, and the threading channel is formed between the two impeller bodies to prevent the safety rope from deviating from the threading channel.

[0011] Preferably, the fixture includes a fixing clamp and a plurality of fastening bolts for clamping and fixing the fixing clamp to the component, and the fixing clamp has a clamping groove adapted to the outer contour of the component.

[0012] Preferably, the fixing clamp is fixed with a connecting bolt, and a fixing rod is fixedly connected between the two limiting members. The fixing rod is located on the outside of the fixing clamp and has a connecting hole at its center for the connecting bolt to be inserted and fixed.

[0013] Preferably, the rotating shaft has a hollow structure, and the connecting bolt passes through the connecting hole and rotatably through the rotating shaft to connect with a connecting nut, wherein the outer diameter of the connecting nut is larger than the inner diameter of the connecting hole.

[0014] A method for guiding a safety rope without using a barbed wire guide system is provided. The method includes the following steps:

[0015] Provide at least two guide devices, fix the guide devices to the component at the working position by means of a fastener, and ensure that the number and layout of all guide devices can cover any working position within the safety rope knot range when each guide device serves as a snap-fit ​​fixing point.

[0016] A safety rope is installed so that it passes through the channel formed between the two limiting members and the rotating shaft in each guide device;

[0017] Attach the buckle of the safety belt to the safety rope and slide the buckle freely along the safety rope to the current working position. Use the guide device that can cover the current working position as the buckle fixing point. Lock the buckle by engaging it in a notch at the current buckle fixing point.

[0018] After completing the work at the current work position, rotate the impeller to disengage the buckle from the notch and slide it along the safety rope to the next buckle fixing point.

[0019] By adopting the above technical solution, the present invention has the following beneficial effects:

[0020] 1) It avoids the pain point of having to constantly hook the safety rope, which can meet the needs of workers' range of movement on the work surface, reduce workers' resistance to wearing safety belts, and ensure a safe working environment for working at heights.

[0021] 2) By setting up the limiting component and the impeller, the safety rope can be limited and guided, and at the same time, the safety belt buckle hooked on the safety rope can pass smoothly through the gap between two adjacent blades on the impeller. Attached Figure Description

The safety belt buckle has a notch 43; two limiting members 22 are fixedly installed on the fixing device 1 and located on both sides of the impeller 4 along the extension direction of the safety rope. Both limiting members 22 are located above the rotating shaft 42 and extend towards the side of the fixing device 1 opposite to the component, so as to form a passage channel between them and the rotating shaft 42 for the safety rope to pass through; preferably, the impeller 4 can switch between a first state of locking the buckle at the current buckle fixing point and a second state of allowing the buckle to slide to the next buckle fixing point by rotating. In the locked state, the buckle is locked in a notch 43 at the current buckle fixing point, and in the sliding state, the buckle disengages from the notch 43 and moves to the next buckle fixing point. It should be noted that in this embodiment, the impeller 4 includes two impeller bodies coaxially fixedly connected to both ends of the rotating shaft 42, and the passage channel is formed between the two impeller bodies to prevent the safety rope from deviating from the passage channel.

[0032] Furthermore, in this embodiment, the fixture 1 includes a fixing clamp 11 and a plurality of fastening bolts 13 for clamping and fixing the fixing clamp 11 to the component, and the fixing clamp 11 has a clamping groove 12 adapted to the outer contour of the component.
