Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting rope protection, and in particular relates to a steel wire rope protection device used for hoisting beams and slabs. Background Art

[0002] The pile-slab bridge is a new type of pile-slab structure, which is a pile-slab consolidation hyperstatic structural system composed of factory-prefabricated bridge decks and prefabricated pipe piles. Compared with traditional roadbed solutions, the pile-slab bridge has high rigidity and small post-construction settlement. It can be used to replace 3 to 8 meters of fill roadbed, which can effectively improve the construction efficiency. During the construction of the pile-slab bridge, it is necessary to use cranes and other lifting equipment to lift the beams for assembly. In the process of lifting the beams, steel wire ropes are sleeved on both ends of the beams, and wear will occur at the corners between the steel wire ropes and the side and bottom of the beams, which will cause safety hazards due to the wear of the steel wire ropes. In the prior art, baffles and other items are set at the contact points between the steel wire ropes and the beam corners to reduce the wear between the steel wire ropes and the beams. However, the above method is cumbersome and complicated, and baffles and other items of different sizes are required for beams of different sizes. Based on this, we propose a device that can protect the steel wire rope when lifting the beam slab. Utility Model Content

[0021] In this embodiment, the bottom protection assembly 2 includes a second protective plate 21, one end of the second protective plate 21 is arc-shaped and tilted, and a second ring 22 is fixedly installed at the bottom end of the second protective plate 21, and the second ring 22 is sleeved on the surface of the wire rope.

[0022] Specifically, by setting the second ring 22, the position of the second protective plate 21 on the surface of the wire rope can be adjusted, so that the second protective plate 21 is placed on both sides of the bottom of the beam and the arc-shaped raised portion of the end is placed on the side of the beam. The second protective plate 21 and the arc-shaped raised portion of the end can effectively reduce the wear between the wire rope and the bottom of the beam.

[0023] In this embodiment, the limiting assembly 18 includes a connecting rod 181. The top of the first protective plate 11 is provided with a mounting hole 3. The connecting rod 181 is inserted and installed in the mounting hole 3. The top of the connecting rod 181 is fixedly connected with a fixing block 182. The surface of the connecting rod 181 is sleeved with a spring 183. The two ends of the spring 183 are respectively connected to the first protective plate 11 and the fixing block 182. One end of the connecting rod 181 located in the first protective plate 11 is fixedly connected with a tooth tip 184. The tooth tip 184 is meshed with the gear. The size of the connecting rod 181 matches the size of the mounting hole 3.

[0024] Specifically, when the first protective plate 11 is placed on both sides of the beam, the insertion rod 14 is pulled outward, and the two insertion rods 14 are moved away from each other with the cooperation of the tooth marks 16, so that the side of the beam can be set between the two clamps 15, and the tooth tip 184 is engaged with the adjusting gear 13, so that the adjusting gear 13 can be limited and fixed to prevent the adjusting gear 13 from rotating, so that the position of the insertion rod 14 can be fixed, and then the position of the clamp 15 can be fixed. In this way, the stability of the side protection assembly 1 during use can be improved.

[0025] In this embodiment, the number of the side protection components 1 and the number of the bottom protection components 2 are both two, and the two bottom protection components 2 are located between the two side protection components 1 .

[0026] Specifically, through this arrangement, when the two bottom protection components 2 are respectively placed at the bottom of the beam and slab, the two side protection components 1 can be respectively placed on both sides of the beam and slab, so that the side protection components 1 and the bottom protection components 2 can respectively protect the steel wire rope and the corners of the beam and slab, thereby reducing the wear of the steel wire rope and the surface of the beam and slab.

[0027] Working principle: When the beam is hoisted, the positions of the first protective plate 11 and the second protective plate 21 are adjusted respectively by the first ring 17 and the second ring 22, so that the two first protective plates 11 are respectively placed on both sides of the beam and the second protective plates 21 are located on both sides of the bottom of the beam. The connecting rod 181 is pulled up to separate the tooth tip 184 from the adjusting gear 13, and then the position of the plug rod 14 is adjusted, so that the tooth marks 16 on the surface of the plug rod 14 can drive the adjusting gear 13 to rotate, and then the two plug rods 14 are moved toward or away from each other under the action of the adjusting gear 13 to adjust the position of the clamping plate 15, so that both sides of the beam are clamped between the clamping plates 15, and through The setting of this structure enables the side protection assembly 1 to adapt to the side protection of beams and slabs of different sizes. Then, the connecting rod 181 is loosened, and the connecting rod 181 is inserted downward under the action of the spring 183. Then, under the action of the tooth tip 184, the adjusting gear 13 can be limited and fixed, and the position of the insertion rod 14 can be fixed, thereby improving the stability of the side protection assembly 1 during use. The arc-shaped raised part at the end of the second protective plate 21 can prevent the steel wire rope from contacting the bottom side of the beam and slab. The first protective plate 11 and the second protective plate 21 can prevent the steel wire rope from contacting the corner of the beam and slab, thereby reducing the wear between the steel wire rope and the beam and slab, and improving the safety of beam and slab lifting.
