Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary structures of hoisting equipment, in particular to a steel wire rope protection device for hoisting section steel. Background Art

[0002] In the prior art, during the hoisting of large steel components, precast concrete components, etc., very high requirements are often placed on the safety, appearance quality, and applicability of the components during the construction process. In general lifting and hoisting situations, a lifting wire rope is used to directly connect to the component lifting point, and the other end is connected to the hook of the lifting machinery. In this case, the lifting wire rope has an angle with the plane, and the lower part of the wire rope is in direct contact with the steel section. The wire rope is triangular as a whole, and the same wire rope has a lateral component of inward extrusion on both sides of the steel section, so that an inward pressure is generated in the horizontal direction, which is borne by the component itself. In the lifting process of large components, due to the large weight of the large components, the horizontal pressure is too large, which can easily cause the large components to be squeezed and deformed, have missing edges and corners, and have anti-corrosion and fireproof coatings damaged during the lifting process. In severe cases, it can lead to component damage, which can easily cause major quality and safety accidents, is not conducive to safe and civilized management and protection of component quality, and is not conducive to the safety of surrounding facilities and destroys the image of civilized construction. At present, the existing technology usually puts a rubber tube on the wire rope as an isolation layer to reduce the wear of the wire rope by the sharp corners of the hoisted heavy objects. However, the above method does not achieve the expected purpose in actual use. After the rubber tube is damaged, the wire rope will still be worn and broken, and its service life will be greatly reduced.

[0003] The Chinese utility model patent application number: 202122637457.1 discloses a steel section hoisting wire rope protection device, including a protection device body, the inner side surface of the protection device body is processed into an L-shaped structure for supporting the steel section to be hoisted, and the outer side surface is processed into an arc-shaped structure, and a wire rope guide unit is provided on the outer side surface, and the outer side surface of the protection device body is composed of a vertical section, a horizontal section, and an arc section connecting the vertical section and the horizontal section. However, the structure of this type of steel section hoisting wire rope protection device is too simple. It puts the L-shaped protection device body on the hoisting steel wire to protect the wire rope. During the hoisting process, relative sliding is likely to occur between the protection device body and the wire rope, which affects the hoisting stability and may cause the steel section to fall off, posing certain safety hazards.

[0026] The adjusting assembly includes an adjusting base 4, an adjusting motor 5, an adjusting shaft 6, an adjusting ratchet 7 and an angle-adjusting ratchet bar 8.

[0033] Working principle:

[0034] When it is necessary to hoist the profiled steel, install the wire rope protection device on the wire rope. First, set the locking rope sleeve 11 on the wire rope, and then set the handcuff-like structure composed of the adjusting ratchet bar and the locking collar 3 on the outside of the corresponding locking rope sleeve 11. Then, drive the adjusting shaft 6 and the adjusting ratchet 7 to rotate through the adjusting motor 5, so that the adjusting ratchet bar contracts to reduce the inner diameter of the handcuff-like structure formed by the adjusting ratchet bar and the locking collar 3. Then, tighten the locking screw to fixedly connect the locking ratchet 10 with the adjusting base 4. The locking ratchet 10 cannot rotate to lock the adjusting shaft 6 and the adjusting ratchet 7 through the connecting ratchet 9, realizing the relative locking between the locking mechanism and the wire rope. Then, limit and guide the lower part of the wire rope through the limit block 17. Place the profiled steel on the L-shaped supporting structure composed of the supporting pillar 12, the supporting cross beam 13 and the supporting protective pad 14, and the profiled steel can be hoisted.

[0035] The beneficial effects of the present utility model are that there is a cooperation between the locking mechanism and the supporting mechanism, which can stably assemble the supporting mechanism on one side of the wire rope, avoiding the falling-off phenomenon of the supporting mechanism. The tightening and loosening adjustment between the locking mechanism and the wire rope is realized through the cooperation of the ratchet and the ratchet teeth, and the adjustment is simple and fast. The supporting mechanism provides support for the wire rope, which can effectively protect the wire rope during the hoisting process, being beneficial to improving the safety of hoisting. There is a limiting mechanism, which can cooperate with the locking mechanism to limit and guide the wire rope to improve the hoisting stability.

[0036] The above has described in detail an embodiment of the present utility model, but the content is only the preferred embodiment of the present utility model and cannot be considered as limiting the implementation scope of the present utility model. All equal changes and improvements made according to the scope of the application of the present utility model shall still fall within the scope covered by the patent of the present utility model.
