[0034] In related technologies, steel supports are fixed only by welding, resulting in low structural strength and potential safety hazards.

[0035] To address the aforementioned technical problems, this application provides a steel-supported anti-fall device.

[0036] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a steel support fall arrestor provided in some embodiments of this application. Figure 2 This is a partial schematic diagram of a steel-supported fall arresting device provided in some embodiments of this application. The steel-supported fall arresting device 100 may include a diaphragm wall 1, a steel support 2, a first steel wire rope 3, a first adjusting member 4, and a fixed bracket 5.

[0037] One end of the steel support 2 is fixed to the diaphragm wall 1. Specifically, one end of the steel support 2 is connected to the diaphragm wall 1, and the other end extends away from the diaphragm wall 1.

[0038] The first wire rope 3 has a fixed opening, and the steel support 2 passes through the fixed opening. Specifically, the first wire rope 3 has a fixed opening that allows the steel support 2 to pass through, so that the first wire rope 3 can be sleeved on the end of the steel support 2.

[0039] The first adjusting member 4 is connected to the first steel wire rope 3 and is used to adjust the size of the fixing opening. Specifically, the first adjusting member 4 is disposed on the first steel wire rope 3, and the size of the fixing opening can be adjusted by adjusting the first adjusting member 4, thereby fixing the first steel wire rope 3 to the steel support 2.

[0040] Along the height of the diaphragm wall 1, the fixing bracket 5 is located on one side of the steel support 2. One end of the fixing bracket 5 is connected to the diaphragm wall 1, and the other end is connected to the first steel wire rope 3. Specifically, along the height of the diaphragm wall 1, the fixing bracket 5 is located above the steel support 2, and the first steel wire rope 3 can be connected to the diaphragm wall 1 through the fixing bracket 5.

[0041] According to the steel support anti-fall device 100 of this application embodiment, by passing the steel support 2 through the fixing opening formed by the first steel wire rope 3, and adjusting the size of the fixing opening by the first adjusting member 4, the first steel wire rope 3 can be connected and fastened to the steel support 2. At the same time, by using the first steel wire rope 3 to connect the steel support 2 to the fixing bracket 5, the steel support 2 can be connected to the fixing bracket 5 through the first steel wire rope 3, thereby preventing the steel support 2 from falling, and thus improving the safety and reliability of the steel support 2.

[0042] Please continue reading. Figure 1 and Figure 2 In some embodiments, the steel support fall arrestor 100 may include a plurality of first adjusting members 4, which are spaced apart on the first steel wire rope 3. By providing a plurality of first adjusting members 4, the reliability of adjusting the size of the fixing opening can be ensured, thereby improving the safety and reliability of the steel support 2.

[0043] The first adjusting element 4 can be a rope clamp. This makes it easy for operators to secure the device and is relatively inexpensive, thus helping to reduce the manufacturing cost of the steel support fall arrestor 100.

[0044] For example, the first adjusting member 4 may include a first adjusting part 41, a first main body part 42, and a first locking part 43. The first main body part 42 may have a first slide rail 421, within which a first locking hole 421 and multiple first sliding grooves may be provided. The first locking hole 421 penetrates the first slide rail 421. The first adjusting part 41 slidably passes through the first slide rail 421, and the first adjusting part 41 may have a first protrusion 411 that mates with the first sliding grooves. The first adjusting part 41 also has a fixing hole 412 and a mounting groove 413 penetrating through it, and the first steel wire rope 3 passes through the mounting groove 413. The first locking part 43 is used to pass through the locking hole and the fixing hole 412. Specifically, when it is necessary to fix the first wire rope 3, a portion of the first wire rope 3 passes through the mounting groove 413, and the first adjusting part 41 slides along the first slide rail 421. When a portion of the first wire rope 3 contacts the first main body part 42, the first protrusion 411 engages with the first slide rail, and the first locking part 43 passes through the first locking hole 421 and the fixing hole 412, thus fixing the first wire rope 3. This structure is simple and facilitates quick fixing of the first wire rope 3.

[0045] Please continue reading. Figure 1 and Figure 2 In some embodiments, the steel support fall arrestor 100 may further include a second steel wire rope 6. The second steel wire rope 6 forms an installation opening, through which the fixing bracket 5 passes. The first steel wire rope 3 is connected to the fixing bracket 5 via the second steel wire rope 6. The first steel wire rope 3 and the second steel wire rope 6 are integral components. This improves the connection strength between the first steel wire rope 3 and the second steel wire rope 6, and also facilitates the fixing of the first steel wire rope 3 and the second steel wire rope 6, thereby reducing assembly difficulty and improving work efficiency.

[0046] Please continue reading. Figure 1 and Figure 2 In some embodiments, the steel support fall arrestor 100 may further include a second adjusting member 7. The second adjusting member 7 is connected to the second steel wire rope 6 and is used to adjust the size of the installation opening. By providing the second adjusting member 7, the size of the installation opening can be directly adjusted, thereby facilitating installation by workers. It also strengthens the structural strength of the second steel wire rope 6.

[0047] For example, the second adjusting member 7 can also be a rope clamp.

[0048] Please continue reading. Figure 1 and Figure 2 In some embodiments, the second wire rope 6 and the steel support 2 have a first included angle A, the value of which satisfies: 45°≤A≤60°. By limiting the angle between the second wire rope 6 and the steel support 2, the second wire rope 6 can better pull the first wire rope 3, preventing the steel support 2 from falling, thereby improving the stability and reliability of the steel support 2.

[0049] For example, the first included angle A can be 45°, 46°, 47°, 48°, 49°, 50°, 51°, 52°, 53°, 54°, 55°, 56°, 57°, 58°, 59°, 60°, etc.

[0050] Please continue reading. Figure 1 and Figure 2 In some embodiments, the steel-supported fall arrestor 100 may also include turnbuckles. The first steel wire rope 3 is connected to the fixed bracket 5 via turnbuckles. This facilitates the connection of the first steel wire rope 3 to the diaphragm wall 1, thereby improving the assembly efficiency of the steel-supported fall arrestor 100.

[0051] Please continue reading. Figure 1 and Figure 2In some embodiments, the diameter of the first wire rope 3 is greater than or equal to 20 mm. By limiting the diameter of the first wire rope 3, the supporting effect of the first wire rope 3 on the steel support 2 can be guaranteed, and the steel support 2 can be prevented from falling.

[0052] For example, the diameter of the first wire rope 3 can be 20mm, 21mm, 22mm, 23mm, etc.

[0053] Please continue reading. Figure 1 and Figure 2 In some embodiments, the fixing bracket 5 may include a first fixing part 51 and a second fixing part 52. The first fixing part 51 is fitted against the side wall of the diaphragm wall 1 and connected to the diaphragm wall 1 by expansion bolts 53. The second fixing part 52 extends from the edge of the first fixing part 51 in a direction away from the diaphragm wall, and the first steel wire rope 3 is connected to the second fixing part 52. Specifically, the fixing bracket 5 may be formed in an "L" shape. Thus, the first fixing part 51 can be more firmly fixed to the diaphragm wall 1, and the fixing method is simple, which helps to reduce costs. At the same time, the setting of the second fixing part 52 allows the operator to better connect the first steel wire rope 3 to the second fixing part 52, which can reduce the difficulty of connection and thus help to improve work efficiency.

[0054] Please continue reading. Figure 1 and Figure 2 In some embodiments, there are multiple first steel wire ropes 3, which are spaced apart on the steel support 2. This further improves the fixation of the steel support 2, thereby enhancing the stability and reliability of the fixation of the steel support 2.

[0055] Please continue reading. Figure 1 and Figure 2 In some embodiments, the steel support fall arrestor 100 may further include an anti-slip element 8. The anti-slip element 8 may have multiple anti-slip protrusions. The anti-slip element 8 covers the surface of the first steel wire rope 3, and the anti-slip protrusions contact the steel support 2. This increases the friction between the first steel wire rope 3 and the steel support 2, preventing the steel support 2 from moving during fixing, thereby improving the stability and reliability of the steel support 2's fixation.

[0056] For example, the surface of the steel support 2 that contacts the anti-slip component 8 can also be fixed with an anti-slip structure, which can further improve the anti-slip effect.

[0057] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0058] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
