[0039] A limiting blind hole 6 is arranged on the core rod body 5, the number of the limiting blind hole 6 is several, the limiting blind hole 6 is uniformly arranged from the upper part of the core rod body 5 to the lower part of the core rod body 5, and the opening of the limiting blind hole 6 faces forward; a core L-shaped limiting hook 7 is fixedly arranged on the upper end of the core rod body 5; an auxiliary limiting protrusion 8 is fixedly arranged on the upper side of the front part of the middle core frame 1; the L-shaped limiting hook 7 and the auxiliary limiting protrusion 8 are hooked on the side wing part of the H-shaped steel, which ensures that the device does not separate from the side wing part of the H-shaped steel, and ensures stability.
[0040] A core rotating plate body 9 is rotatably arranged in the middle inner part of the middle core frame 1 through a hinged connection, the middle upper part of the core rotating plate body 9 is rotatably connected with the middle inner part of the middle core frame 1,
[0041] A limiting pin 10 is arranged on the upper rear side of the core rotating plate body 9, the limiting pin 10 penetrates through the front wall of the guide pipe body 4 and extends into the interior of the guide pipe body 4, the limiting pin 10 is inserted into the limiting blind hole 6 arranged on the core rod body 5, which plays a limiting role and limits the sliding of the core rod body 5 on the guide pipe body 4.
[0042] A spring 11 is arranged on the upper front part of the core rotating plate body 9, the other end of the spring 11 extends forward, and the front distal end of the spring 11 is fixedly connected with the inner wall of the front part of the middle core frame 1.
[0043] Preparation work:
[0044] Firstly, the user needs to check whether each component of the device is intact, including the middle core frame 1, the U-shaped frame body 2, the construction safety rope 3, the guide pipe body 4, the core rod body 5, the limiting blind hole 6, the core L-shaped limiting hook 7, the auxiliary limiting protrusion 8, the core rotating plate body 9, the limiting pin 10, and the spring 11, etc., to ensure that each component is firmly connected without looseness, deformation or damage, etc.
[0045] Confirm that the length and strength of the construction safety rope 3 meet the safety standards, and that the other end can be normally tied to the designated position on the safety vest worn by the worker, and ensure that the buckle is firmly and reliably tied and will not accidentally come loose during use.
[0046] Install to the H-shaped steel side wing part:
[0047] The user holds the device, places the middle core frame 1 close to the H-shaped steel side wing part, and aligns the core L-shaped limiting hook 7 and the auxiliary limiting protrusion 8 with the corresponding positions of the H-shaped steel side wing part.
[0048] If the distance between the L-shaped limiting hook 7 and the middle core frame 1 is not suitable for the size of the current H-shaped steel side wing part, the user needs to press the core rotating plate body 9 with his hand, and the pressing position is at the middle and lower part of the core rotating plate body 9, so as to facilitate the application of appropriate pressure. At this time, the core rotating plate body 9 rotates around the hinge point, and the limiting pin 10 on the rear side of the upper part of the core rotating plate body 9 gradually comes out of the limiting blind hole 6 on the core rod body 5, and the spring 11 is compressed. The front part of the spring 11 moves towards the inner wall of the front part of the middle core frame 1 with the rotation of the core rotating plate body 9, storing elastic potential energy.
[0049] When the limiting pin 10 completely comes out of the limiting blind hole 6, the user can move the core rod body 5 up and down along the guide pipe body 4. Since the cross sections of the guide pipe body 4 and the core rod body 5 are both square, the core rod body 5 will not rotate when sliding in the guide pipe body 4, ensuring the stability of the movement. By adjusting the position of the core rod body 5, the distance between the L-shaped limiting hook 7 and the middle core frame 1 can be appropriately hooked to the H-shaped steel side wing part.
[0050] When the distance is adjusted appropriately, the user slowly releases the pressing of the core rotating plate body 9, and the spring 11 releases the elastic potential energy, pushing the core rotating plate body 9 to rotate in the opposite direction. The limiting pin 10 will reinsert into the corresponding limiting blind hole 6 on the core rod body 5 under the action of the spring 11. During the insertion process, the user can appropriately fine-tune the position of the core rod body 5 to ensure that the limiting pin 10 is accurately inserted into the limiting blind hole 6, thereby limiting the sliding of the core rod body 5 on the guide pipe body 4 and ensuring that the L-shaped limiting hook 7 and the auxiliary limiting protrusion 8 are stably hooked to the H-shaped steel side wing part, so that the entire device is firmly installed on the H-shaped steel side wing part and will not easily come off.
[0051] Use during construction:
[0052] After the device is installed, the user ties the construction safety rope 3 to his safety clothes, ensures that the safety rope is not entangled or knotted, and can freely stretch without hindering the construction action.
[0053] When the user is working at a high place in a steel structure factory, such as walking, climbing, and carrying tools during the operation process, the middle core frame 1 of the device is always stably fixed on the side wing of the H-shaped steel through the L-shaped limiting hook 7 and the auxiliary limiting protrusion 8, and the construction safety rope 3 stretches or contracts with the movement of the user, providing reliable anti-falling protection for the user. Once the user falls accidentally, the construction safety rope 3 will quickly pull the user to avoid falling to the ground, and at the same time, other parts of the device will also bear the corresponding tension. Due to its stable structure design, it can effectively disperse and bear these tensions, ensuring the safety of the user's life.
[0054] Dismounting from the side wing of the H-shaped steel:
[0055] When the user needs to dismount the device from the side wing of the H-shaped steel after the construction is completed, the operation steps of adjusting the distance between the L-shaped limiting hook 7 and the middle core frame 1 are repeated. That is, first press the core rotating plate body 9 with your hand to compress the spring 11, and then disengage the limiting pin 10 from the limiting blind hole 6 of the core rod body 5, and then move the core rod body 5 so that the L-shaped limiting hook 7 and the auxiliary limiting protrusion 8 can smoothly disengage from the side wing of the H-shaped steel.
[0056] After successfully dismounting the device, the user should conduct a comprehensive inspection and maintenance of the device, clean the debris, dust, and other impurities that may be attached to the device, check whether each part is worn, deformed, or damaged, and if there is a problem, it should be repaired or replaced in time so that it can be used normally next time.
[0057] Through the above detailed implementation, the user can correctly, safely, and effectively use the new type of steel structure factory high-altitude construction anti-falling device to provide reliable safety protection for high-altitude construction.
[0058] Stable and firm fixation on the side wing of the H-shaped steel:
[0059] The device hooks the side wing of the H-shaped steel through the core L-shaped limiting hook 7 and the auxiliary limiting protrusion 8. This double limiting structure can fix the device from different directions, ensuring that the device is tightly connected with the side wing of the H-shaped steel, providing a stable and reliable support point for the construction personnel, greatly reducing the risk of falling due to the loosening or falling of the device.
[0060] The stable cooperation between the middle core frame 1, the guide pipe body 4 and the core rod body 5 further enhances the stability of the whole device. The square cross-section design of the guide pipe body 4 and the core rod body 5 ensures that the core rod body 5 does not rotate when sliding in the guide pipe body 4, so that the L-shaped limiting hook 7 can remain stable after adjusting the position, thereby making the fixation of the whole device on the side wing of the H-shaped steel more firm.
[0061] Adapting to different sizes of H-shaped steel side wings:
[0062] The core rod body 5 is provided with limiting blind holes 6, and the number is several, which are uniformly arranged from the upper part to the lower part. The user can adjust the position of the core rod body 5 in the guide pipe body 4 by pressing the core rotating plate body 9, so as to change the distance between the L-shaped limiting hook 7 and the middle core frame 1. This flexible adjustment mode makes the device adapt to different sizes of H-shaped steel side wings, improves the versatility and practicality of the device, reduces the trouble of preparing multiple specifications of anti-falling devices due to the size difference of H-shaped steel, and reduces the construction cost and resource waste.
[0063] Convenient operation: The operation design of the device is simple and intuitive, and the user only needs to press the core rotating plate body 9 to adjust the position of the core rod body 5, and then complete the installation and disassembly operation of the device on the side wing of the H-shaped steel. The whole operation process does not need complex tools or professional skills, and the construction personnel can quickly get started, saving construction time and labor cost, and improving construction efficiency.
[0064] The construction safety rope 3 is directly arranged on the U-shaped frame body 2, and the other end is tied to the safety clothes worn by the worker. The buckle is simple and clear, and the user can quickly complete the connection of the safety rope before construction, ensuring that the safety protection is in place in time during the construction process.
[0065] High safety: The stable and firm fixation mode and the adaptability to different sizes of H-shaped steel side wings fundamentally guarantee the reliability of the device during use, effectively preventing falling accidents caused by unstable fixation of the device.
[0066] The construction safety rope 3 as the last line of defense can timely pull the construction personnel when an accident occurs, avoiding falling to the ground. Combined with the overall structure of the device, it forms a multiple safety protection mechanism, greatly improving the safety of high-altitude construction and providing strong protection for the life safety of the construction personnel.
[0067] The above has described the utility model and its implementation mode, which is not restrictive, and the drawings only show one of the implementation modes of the utility model, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired thereby, without departing from the creative purpose of the utility model, similar structural modes and embodiments are not creatively designed, which should belong to the protection scope of the utility model.
