Description

Technical Field

[0001] This invention belongs to the technical field of construction safety measures, specifically relating to a safety belt fixing device for high-altitude operations and its usage method. Background Technology

[0002] In the construction of large-span steel structure workshops and stadiums, steel roof installation is a typical high-altitude, edge-prone operation. During steel beam installation, it is difficult to secure workers' safety belts, and finding anchor points is challenging. Traditionally, construction teams weld columns onto the steel structure and thread steel cables across them. However, this traditional safety belt securing method has the following drawbacks: 1. Discontinuous anchor points: Workers need to frequently change the safety belt attachment points, resulting in unprotected gaps during the transfer process, which poses an extremely high risk of falling. 2. Destructive fixing methods: These methods often involve welding temporary ear plates or drilling, which damages the base material and increases the cost of subsequent rust prevention treatment. 3. Poor adaptability: Traditional steel wire rope flexible tracks are prone to sagging and swaying, making it difficult to ensure levelness and providing stable horizontal movement support; 4. Low turnover efficiency: Temporary measures are difficult to dismantle and cannot be quickly moved to another location for reuse. Summary of the Invention

[0003] To address the aforementioned technical problems, we provide a field solution that is easy to assemble and disassemble, safe, reliable, and highly adaptable.

[0004] The technical solution adopted by the present invention to solve the aforementioned problem is as follows: A safety belt fixing device for high-altitude operations includes a column, a connecting seat at the lower end of the column, and a safety rope suspension mechanism at the upper end of the column. The connecting seat includes a U-shaped clip and a high-strength bolt. The U-shaped clip is fastened to the structural plate of the high-altitude building. The high-strength bolt is inserted through the bottom plate of the U-shaped clip, and the end of the high-strength bolt abuts against the surface of the structural plate. The safety rope suspension mechanism includes a track, a sliding block is provided inside the track, and a neck column is fixedly connected to the surface of the sliding block. The neck column is set in the groove of the track and its upper end extends out of the track. A hanging ring is fixedly connected to the outer end of the neck column.

[0005] Compared with the prior art, the present invention employing the above structure has the following advantages: This invention, through a modular design that combines rigid tracks and sliding supports, achieves continuous, non-destructive, and reusable safety protection for workers performing high-altitude operations during the installation of large-span steel roofs. It has significant safety and economic advantages and is suitable for widespread application.

[0006] As a preferred option, a further technical solution to the above structure is: The track is made of steel pipe, and the groove of the track is a through hole set axially on the surface of the steel pipe. The sliding block is a sphere that is movably set inside the steel pipe. Steel pipe is a low-cost and easy-to-manufacture track with a large internal space. The sphere chosen for the sliding block has low friction with the inner wall of the steel pipe, allowing it to move smoothly in the cavity.

[0007] The track consists of multiple segments, with an internally threaded connection at one end and an externally threaded connection at the other. The length of the steel pipe is compensated and adjusted through these internal and external threaded connections.

[0008] Stop blocks are installed at both ends of the track to prevent the ball from coming out of the steel pipe and to ensure safety.

[0009] A rubber friction pad is installed between the top plate of the U-shaped clamp and the structural plate to improve the connection stability between the U-shaped clamp and the H-shaped steel beam.

[0010] The above-mentioned high-altitude work safety belt fixing device is used in the following way: Step 1, Ground Pre-assembly: Based on the span of the steel beam, multiple steel pipe segments are connected on the ground through internal and external threaded connections to form a complete track. The straightness of all segments is adjusted and pre-tightened to ensure that the tracks of each segment are aligned.

[0011] Step 2, Install the connector: A connecting seat is arranged approximately every 3 meters on the flange of the steel beam. U-shaped clips are then attached to the flange of the steel beam, high-strength bolts are inserted, and wrenches are used to tighten them simultaneously, so that the rubber friction pads are in close contact with the steel beam.

[0012] Step 3, Install the track: The pre-assembled track is hoisted to the top of the column and fixed to the top of the column with connectors. The track level is adjusted to ensure that the whole track is straight.

[0013] Step 4, Install the sliding block: Install the sliding blocks one by one into the track from the end of the steel pipe. The number of sliding blocks is determined according to the number of workers. After installation, test whether the sliding is smooth. After confirming that there are no problems, seal both ends of the steel pipe and install stop blocks at both ends of the track or at the bend.

[0014] Step 5, Safe Use: Workers directly fasten their safety belt hooks into the safety rings of the sliding support. When moving along the steel beam, the sliding block slides along the track with the workers.

[0015] Step 6, Dismantling and Relocation: After the work is completed, the connecting seat is removed, the device is released from the steel beam, the track is dismantled in sections, the steel pipe is separated section by section, the sliding block is removed and cleaned and inspected, all components are hoisted to the ground, packaged and transferred to the next work surface for reassembly and use.

[0016] Compared with the prior art, the present invention employing the above method has the following advantages: 1) Workers can move continuously along the track without changing the attachment points, achieving full-process fall protection; 2) Clamping fixation eliminates the need for welding or drilling, protecting the steel beam base material; 3) Rigid tracks are not prone to sagging or swaying, providing stable support; 4) Modular design allows for quick installation, dismantling, and reuse; 5) The track length can be adjusted according to the span to adapt to different engineering needs.

[0019] The present invention will be further described below with reference to embodiments, which are intended only to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0020] See Figures 1 to 5 This invention provides a safety belt fixing device for high-altitude operations, including a column 3, a connecting seat 2 at the lower end of the column 3, and a safety rope suspension mechanism at the upper end of the column 3. The connecting seat 2 includes a U-shaped clip 21 and a high-strength bolt 22. The U-shaped clip 21 is fastened to the structural plate of the high-altitude building, and the high-strength bolt 22 is provided through the bottom plate of the U-shaped clip 21. The end of the high-strength bolt 22 abuts against the surface of the structural plate. The safety rope suspension mechanism includes a track 4, a sliding block 5 is provided inside the track 4, and a neck column 6 is fixed to the surface of the sliding block 5. The neck column 6 is set in the groove of the track 4 and its upper end extends out of the track 4. A hanging ring 7 is fixed to the outer end of the neck column 6.

[0021] The structural slab of the high-rise building is an H-shaped steel beam 1, and the connecting seat 2 is installed on the wing plate of the H-shaped steel beam 1; each connecting seat 2 has three high-strength bolts 22, arranged in a triangular pattern.

[0022] Alternatively, the track 4 can be a steel pipe, with the groove being an axially oriented through hole on the surface of the steel pipe. The sliding block 5 is a sphere movably disposed within the steel pipe. Using a steel pipe as the track 4 results in low cost, ease of manufacture, and a large internal space. The selection of a sphere as the sliding block 5 minimizes friction with the inner wall of the steel pipe, allowing for smooth movement within the cavity.

[0023] The track 4 of this invention is composed of multiple segments 41. Specifically, one end of segment 41 has an internally threaded connection end 401 on its inner wall, and the other end has an externally threaded connection end 402. The length compensation and adjustment of the steel pipe are achieved through the internal and externally threaded connection ends 402. The internally threaded connection end 401 is an internal thread milled into the inner wall of the end of segment 41. The externally threaded connection end 402 is connected to a threaded pipe with a smaller outer diameter that is adapted to the internally threaded connection end 401 at the end of segment 41. The threaded pipe is slotted simultaneously.

[0024] Optionally, stop blocks are provided at both ends of track 4 to prevent the ball from coming out of the steel pipe and to ensure safety.

[0025] Optionally, a rubber friction pad is provided between the top plate of the U-shaped clip 21 and the structural plate to improve the connection stability between the U-shaped clip 21 and the H-shaped steel beam 1.

[0026] The length of each segment 41 of the track 4 is selected according to the number of columns 3. One or two connectors 8 can be set on the lower side of the segment 41 for detachable connection with the column 3. Specifically, threaded connection, plug-in or snap-fit ​​fixing can be selected.

[0027] The above-mentioned high-altitude work safety belt fixing device is used in the following way: Step 1, Ground Pre-assembly: Based on the span of steel beam 1, multiple steel pipe segments 41 are connected on the ground through internal and external threaded connection ends 402 to form an integral track 4. The straightness of all segments 41 is adjusted and pre-tightened to ensure that the track 4 of each segment 41 is aligned.

[0028] Step 2, Install connector 2: A connecting seat 2 is arranged every 3 meters on the flange of steel beam 1. The U-shaped clip 21 is clipped onto the flange of steel beam 1, and high-strength bolts 22 are inserted. The bolts are tightened simultaneously with a wrench so that the rubber friction pad is tightly attached to steel beam 1.

[0029] Step 3, Install the track: The pre-assembled track 4 is hoisted onto the upper part of the column 3 and fixed to the upper end of the column 3 with connectors. The level of the track 4 is adjusted to ensure that the whole is straight.

[0030] Step 4, Install slider 5: Insert the sliding blocks 5 one by one into the track 4 from the end of the steel pipe. The number of sliding blocks 5 is determined according to the number of workers. After installation, test whether the sliding is smooth. After confirming that there are no problems, seal both ends of the steel pipe and install stop blocks at both ends of the track 4 or at the bend.

[0031] Step 5, Safe Use: The worker directly fastens the safety belt hook into the safety ring 7 of the sliding support. When moving along the steel beam 1, the sliding block 5 slides with the worker in the track 4.

[0032] Step 6, Dismantling and Relocation: After the work is completed, remove the connecting seat 2, release the device from the steel beam 1, dismantle the track 4 in sections, separate the steel pipes section by section, take out the sliding block 5 and clean and inspect each component, hoist all components to the ground, package and transfer them to the next work surface for reassembly and use.

[0033] In the installation project of the roof of a steel structure factory building with a span of 42 meters, the device of this invention was used. A total of 40 meters of track was set up, with 14 connecting seats and columns and 8 sliding blocks. The installation time was about 2 hours. During the operation, personnel could move smoothly without any gaps in protection. After the construction was completed, the device was completely dismantled and reused in the next factory building without any damage to the components.

[0034] The beneficial effects of this invention are: 1) Continuous protection: Operators can move continuously along the track without changing attachment points, achieving full-process fall protection; 2) Non-destructive installation: It adopts clamping and fixing, which eliminates the need for welding or drilling, thus protecting the steel beam base material; 3) Good stability: Rigid rails are not prone to sagging or swaying, providing stable support; 4) Easy to install and disassemble: Modular design allows for quick installation, disassembly, and reuse; 5) High applicability: The track length can be adjusted according to the span to adapt to different engineering needs.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. All equivalent changes made based on the description and drawings of the present invention are included within the scope of the present invention.
