Description

Technical Field

[0001] This utility model relates to the field of steel structure operation safety technology, and in particular to a steel wire rope fastening system for steel beam operations. Background Technology

[0002] Currently, steel structure engineering is increasingly widely used in super high-rise buildings. In steel-concrete composite tube structures, steel structures are used around the core tube, especially at the ends of steel beams, which are typically connected by anchor bolts and welded. Processes such as grinding the welds and applying anti-rust paint require high-altitude work. Needless to say, safety is paramount in construction. Regulations regarding high-altitude work management stipulate that safety belts should be suspended high and used low, therefore, lifelines for suspending safety belts during high-altitude work must be set up in advance.

[0003] In the past, safety ropes were mostly fixed to temporary operating platforms during steel structure construction. However, once the safety ropes were fixed to the operating platform, they could not move freely. When the operators adjusted their working positions, they had to untie the safety ropes and readjust and fix them to the operating platform. In this process, there was a risk to personal safety if there were any special circumstances such as sudden wind. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a steel wire rope fastening system for steel beam operations, which overcomes the deficiencies of existing technologies and effectively solves the problem that when operators adjust their working positions, they need to untie the safety rope and readjust and fix it to the operating platform, which poses a personal safety risk in the event of sudden winds or other special circumstances.

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

[0006] A steel wire rope fastening system for steel beam operations includes a steel wire rope body. A suspension assembly is fastened to the outer wall of the steel wire rope body, and a fastening assembly is also provided on the outer wall of the steel wire rope body. The suspension assembly includes a connecting plate, a first hanging ring welded and fixed to the bottom of the connecting plate, second hanging rings welded and fixed to both ends of the top of the connecting plate, a safety rope fastened and fixed to the outer wall of the second hanging rings, and a hook fastened and fixed to the top of the safety rope. The fastening assembly includes a fixing rod, a fixing cylinder welded and fixed to the top of the fixing rod, a locking screw screwed to the top of the fixing cylinder, a support plate welded and fixed to the bottom of the fixing rod, a bidirectional screw rod rotatably connected to the support plate, a guide rod welded and fixed through the support plate, L-shaped blocks connected to both ends of the bidirectional screw rod and the guide rod, a handle screw rod rotatably connected to the bottom of the L-shaped blocks, sliding rods welded and fixed to both sides of the bottom of the L-shaped blocks, and a clamping plate screwed to the wall of the handle screw rod.

[0007] By placing the support plate against the top of the steel beam, rotating the double-ended screw drives the screwed L-shaped block to slide along the guide rod. Adjusting the distance between the two L-shaped blocks, and then rotating the handle screw drives the screwed clamp plate to move up and down, clamping the clamp plate and L-shaped block against the steel beam. The wire rope is then passed through the fixed cylinder. The locking screw is tightened downwards at the top of the fixed cylinder, pressing the bottom end of the locking screw down to the bottom of the fixed cylinder and tightly biting the wire rope with the teeth to prevent the wire rope from loosening inside the fixed cylinder. The hooks in the suspension assembly are then fastened to the wire rope. During use, the operator fastens the safety buckle on their body to the first hanging ring. When moving past the fastening assembly, the two hooks are fastened to the wire rope in sequence.

[0008] Preferably, through holes are provided on both sides of the outer wall of the fixed cylinder, and the inner diameter of the through holes is larger than the outer diameter of the wire rope.

[0009] The wire rope is inserted into the fixed cylinder through the through hole.

[0010] Preferably, the bottom end of the locking screw is welded with convex teeth that are evenly distributed.

[0011] By tightening the locking screw downwards at the top of the fixed cylinder, the bottom end of the locking screw presses the wire rope down to the bottom inside the fixed cylinder, and the protruding teeth tightly bite into the wire rope, thus preventing the wire rope from loosening inside the fixed cylinder.

[0012] Preferably, the L-shaped block has a first screw hole and an insertion hole at both ends of one side of its outer wall, and the first screw hole forms a threaded engagement with the bidirectional lead screw, while the insertion hole forms a sliding engagement with the guide rod.

[0013] By rotating the bidirectional lead screw, the screwed L-shaped block slides along the guide rod, which can adjust the distance between the two L-shaped blocks.

[0014] Preferably, the top of the clamping plate is provided with a second screw hole, and the first screw hole forms a threaded engagement with the handle screw.

[0015] By turning the handle screw, the screwed clamp plate moves up and down.

[0016] Preferably, the second screw hole is provided with sliding holes on both sides of the bottom of the clamping plate, and the sliding holes and the sliding rod form a sliding fit.

[0017] The sliding rods provide guidance and support for the up-and-down movement of the clamping plate.

[0018] The beneficial effects of this utility model are as follows:

[0019] By placing the support plate against the top of the steel beam, adjusting the distance between the two L-shaped blocks by rotating the double-acting screw, and then rotating the handle screw to clamp the clamping plate and L-shaped blocks onto the steel beam, the wire rope is passed through the fixed cylinder. Tightening the locking screw presses the wire rope down to the bottom to prevent it from loosening inside the fixed cylinder. The hooks in the suspension assembly are then fastened to the wire rope. During use, the operator fastens their safety buckle to the first hanging ring. When moving past the fastening assembly, the two hooks are fastened to the wire rope sequentially. This effectively solves the problem in existing technologies where operators need to unfasten the safety rope and readjust their position on the operating platform when adjusting their work position, which poses a personal safety risk in case of sudden winds or other special circumstances.
