Description

Technical Field

[0001] This invention relates to the field of safety devices for construction operations, and in particular to a mobile safety belt padlock device for high-altitude operations. Background Technology

[0002] In the construction of superstructures for building projects such as elevated highways and bridges, it is mandatory to wear professional safety belts to prevent workers from accidentally falling. The current mainstream protection method is safety rope protection: one end of the safety belt worn by the worker is connected to the safety rope, and the other end is fixed to the body. When walking, the safety belt moves synchronously along the safety rope to achieve fall protection.

[0003] In existing technologies, safety ropes are typically erected on construction platforms such as steel beams and trusses by setting fixed posts at both ends or adding transition posts in the middle. This method has significant drawbacks: firstly, the additional post installation and safety rope erection are time-consuming and labor-intensive, affecting construction efficiency; secondly, when the safety belt moves to the vicinity of the transition post, it is often difficult to pass smoothly. It is necessary to first detach the safety belt from the safety rope on one side of the transition post and then reattach it to the safety rope on the other side of the transition post. During this process, the safety belt is temporarily without an attachment point, still leaving a risk of fall. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a mobile safety belt padlock device for high-altitude operations. This device has a simple and reasonable structure, is safe, convenient, reliable, and stable to use, and can effectively replace the traditional safety rope protection scheme, thereby significantly optimizing the protection effect for high-altitude operations.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A mobile safety belt padlock device for high-altitude operations includes: The walking frame is in or approximately U-shaped, can be fitted onto the outer surface of the building structure, can move relative to the building structure, and is limited in position to the building structure along the direction of the walking frame's fall. A roller device is provided on the traveling frame. The roller device includes rollers, at least a portion of which is located inside the traveling frame. When the traveling frame is fitted onto the building structure, the rollers roll in contact with the outer surface of the building structure. An anchoring device, which is fixedly connected or limited to the traveling frame, and is used to connect the safety belt.

[0007] Furthermore, the traveling frame includes a main beam and side beams respectively disposed at both ends of the main beam. The side beams are fixedly connected or limited to the main beam. The extension direction of the main beam is defined as a first direction. When the traveling frame is fitted onto the outer surface of the building structure, the side beams can at least restrict the degree of freedom of the traveling frame along the first direction.

[0008] Furthermore, the roller includes a first roller, and the roller assembly includes a first roller frame, the first roller frame being disposed on the inner side of the main beam, and the first roller being rotatably disposed on the first roller frame.

[0009] Furthermore, a reinforcing beam is provided between the main beam and the side beam, and the reinforcing beam is provided with a connecting rod, with the first roller frame disposed on the connecting rod.

[0010] Furthermore, the direction in which the walking frame moves relative to the building structure is defined as the second direction, and the connecting rod extends along the second direction.

[0011] Furthermore, the roller includes a second roller, and the roller assembly includes a second roller frame, the second roller frame being disposed on the inner side of the side beam, and the second roller being rotatably disposed on the second roller frame.

[0012] Furthermore, the anchoring device is configured as an anchoring ring, which is disposed on the side beam.

[0013] Furthermore, the anchoring ring is disposed at the end of the side beam away from the main beam.

[0014] Furthermore, each of the side beams is provided with the anchoring ring.

[0015] Furthermore, the walking frame is made of stainless steel.

[0016] The beneficial effects of this invention are as follows: The mobile safety belt padlock device for high-altitude operations provided by this invention, through the setting of a walking frame in a shape or approximately "U" shape, and the installation of roller devices and anchoring devices on the walking frame, allows for easy use. In operation, the walking frame is fitted onto the outer surface of the corresponding building structure, and the safety belt is connected to the anchoring device. Through the interaction between the walking frame and the building structure, when workers move along the construction platform, they use their safety belts to pull the walking frame relative to the building structure, thus not affecting the workers' work. Simultaneously, the fall protection effect of the building structure on the walking frame is utilized to achieve fall protection for the workers. Compared with existing technologies, this invention has a simple and reasonable structure, is safe, convenient, reliable, and stable in use, and can effectively replace traditional safety rope protection schemes, significantly optimizing the protection effect for high-altitude operations.

[0019] The invention will now be further described with reference to the accompanying drawings.

[0020] See Figure 1 As shown, a mobile safety belt padlock device for high-altitude operations includes a traveling frame 1, a roller device, and an anchoring device 3. The traveling frame 1 is made of stainless steel to improve its overall strength. The traveling frame 1 includes a main beam 11 and side beams 12 respectively disposed at both ends of the main beam 11. The side beams 12 are fixedly connected to or limited by the main beam 11. In this embodiment, the side beams 12 and the main beam 11 are fixed by welding. Of course, in other embodiments, the side beams 12 and the main beam 11 can also adopt other connection methods, such as fixing them with bolts.

[0021] The side beam 12 is connected to the main beam 11, so that the traveling frame 1 is in or approximately in the shape of a "U". The traveling frame 1 can be fitted onto the outer surface of the building structure. The traveling frame 1 can move relative to the building structure. Furthermore, the traveling frame 1 is limited and matched with the building structure along the falling direction of the traveling frame 1.

[0022] The extension direction of the main beam 11 is defined as the first direction. When the walking frame 1 is fitted onto the outer surface of the building structure, the side beam 12 can at least restrict the degree of freedom of the walking frame 1 along the first direction. That is, along the first direction, the side beam 12 cooperates with the building structure to restrict the degree of freedom of the walking frame 1 relative to the building structure.

[0023] See Figure 2As shown, in some exemplary application scenarios, the mobile safety belt padlock device for high-altitude operations provided by the present invention can be applied to the construction of the elevated cap beam 4: the cap beam 4 is usually placed on the top of the pier 5, the pier 5 is also supported by a truss, the top of the truss has a construction platform 6, the construction platform 6 is located on the side of the top of the pier 5, the extension direction of the construction platform 6 is consistent with the extension direction of the cap beam 4, and the workers can move along the construction platform 6 to carry out construction operations.

[0024] During construction, the traveling frame 1 is first fitted onto the outer surface of the building structure (i.e., the cap beam 4) from top to bottom, with the "U"-shaped opening facing downwards. This ensures that the main beam 11 is located on the upper surface of the building structure, and the side beams 12 are clamped onto the side surface. When workers move along the construction platform 6, they use safety belts to pull the traveling frame 1 along the building structure. When a traction force is applied to the traveling frame 1 along the extension direction of the building structure, the traveling frame 1 can move relative to the building structure. When a force is applied to the traveling frame 1 along the falling direction, the traveling frame 1 cannot fall off the building structure because both the main beam 11 and the side beams 12 are restrained by the building structure.

[0025] See Figure 1 and Figure 2 As shown, the roller device is installed on the traveling frame 1. The roller device includes rollers, at least a portion of which is located inside the traveling frame 1. When the traveling frame 1 is fitted onto the building structure, the rollers roll in contact with the outer surface of the building structure.

[0026] In this embodiment, the rollers include a first roller 23 and a second roller 24. The roller assembly includes a first roller frame 21 and a second roller frame 22. The first roller frame 21 is disposed on the inner side of the main beam 11, and the first roller 23 is rotatably disposed on the first roller frame 21. The second roller frame 22 is disposed on the inner side of the side beam 12, and the second roller 24 is rotatably disposed on the second roller frame 22. Each side beam 12 is provided with a plurality of second roller frames 22 arranged along the extension direction of the side beam 12. In this embodiment, each side beam 12 is provided with two second roller frames 22. Of course, in other embodiments, each side beam 12 may also be provided with more second roller frames 22.

[0027] By setting a first roller 23 on the inner side of the main beam 11 and a second roller 24 on the inner side of the side beam 12, the rolling cooperation between the rollers and the building structure can reduce the frictional resistance when the traveling frame 1 moves relative to the building structure, making the construction work more labor-saving. On the other hand, it can also reduce the swaying amplitude of the traveling frame 1 relative to the building structure, making the traveling frame 1 more stable in movement.

[0028] See Figure 1 and Figure 2As shown, to improve the connection strength between the main beam 11 and the side beam 12, a reinforcing beam 13 is provided between the main beam 11 and the side beam 12. The reinforcing beam 13 is L-shaped, with one end fixedly connected to the main beam 11 and the other end fixedly connected to the side beam 12. The reinforcing beam 13 is provided with a connecting rod 14, and a first roller frame 21 is provided on the connecting rod 14. The direction in which the walking frame 1 moves relative to the building structure is defined as the second direction, which is also the extension direction of the building structure. The connecting rod 14 extends along the second direction and is provided with several first roller frames 21 arranged along the second direction. In this embodiment, each connecting rod 14 is provided with two first roller frames 21, located at opposite ends of the connecting rod 14 along the second direction. Through the above structural design, when the walking frame 1 is fitted onto the outer surface of the building structure, the first rollers 23 of each first roller frame 21 on the connecting rod 14 can effectively support the walking frame 1, preventing the walking frame 1 from tilting undesirably relative to the building structure.

[0029] See Figure 1 and Figure 2 As shown, the anchoring device 3 is fixedly connected or limited to the traveling frame 1. The anchoring device 3 is used to connect the safety belt. In this embodiment, the anchoring device 3 is set as an anchoring ring, which is welded and fixed to the side beam 12. Specifically, the anchoring ring is located at the end of the side beam 12 away from the main beam 11. By adopting the above structural design, when the traveling frame 1 is fitted onto the building surface, it is not only convenient for workers to connect the safety belt to the anchoring ring, but also, when workers pull the traveling frame 1 with the safety belt, because the anchoring ring is in a relatively low position on the traveling frame 1, it is less likely for the traveling frame 1 to fall relative to the building structure.

[0030] In this embodiment, each side beam 12 is equipped with an anchoring ring to facilitate construction by workers.

[0031] The mobile safety belt padlock device for high-altitude operations provided by this invention features a U-shaped or roughly U-shaped walking frame 1, with rollers and anchoring devices 3 mounted on it. In use, the walking frame 1 is fitted onto the outer surface of the corresponding building structure, and the safety belt is connected to the anchoring device 3. Through the interaction between the walking frame 1 and the building structure, when workers move along the construction platform 6, they use their safety belts to pull the walking frame 1 relative to the building structure. This does not interfere with the workers' work, and the building structure's fall-prevention and limiting effect on the walking frame 1 also provides fall protection for the workers. Compared to existing technologies, this invention has a simple and reasonable structure, is safe, convenient, reliable, and stable in use, and can effectively replace traditional safety rope protection schemes, significantly optimizing the protection effect for high-altitude operations.
