Description

Technical Field

[0001] The invention relates to the technical field of lifting slings, in particular to a fracture-resistant high-strength rigging steel rope for lifting. Background Art

[0002] Lifting lock wire rope refers to the wire rope and its matching lock combination used in lifting and hoisting operations to connect the hoisted object and lifting equipment (such as cranes, hooks, etc.) and bear the load weight. It is the core load-bearing component in lifting operations, mainly used to transmit tension, fix objects or form lifting points. Its safety and reliability directly affect the success of lifting operations and the safety of personnel and equipment.

[0003] The invention of the existing publication number CN114701944B discloses a wire rope hoisting rigging, which includes a balance control box. A hook connected to the wire rope of the crane is installed on the top of the balance control box. The length of the pull rope is adjusted by the wire wheel and the tension adjustment motor to make the steel pipe in a horizontal hoisting state. The tension on the two pull ropes is basically the same, which can effectively prevent the steel pipe from swinging and ensure the safety of the operation. The above scheme avoids the swing of the hoisted objects during lifting and hoisting by controlling and adjusting the two steel ropes. During the lifting and hoisting operation, in addition to the swing of the objects during the lifting process, In addition to the danger it can bring to people, the supporting strength of the lock rope is also crucial. When the lock rope breaks, the cargo will fall and injure people. There are many factors that affect the breakage of the rigging rope. For example, after the wire rope is used for a long time, the deformation and friction between the single wires can easily cause the single wire or wire rope to break. In addition, a heart-shaped ring will be set at the position of the wire rope connection hook to reduce the possibility of wear and tear of the wire rope. When the heart-shaped ring is worn for a long time and needs to be replaced, it is often necessary to disassemble the heart-shaped ring before the heart-shaped ring can be inserted into the ring connection formed by the wire rope, which is inconvenient to maintain and use.

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Please see the attached Figure 1-14 , this application provides the following technical solutions.

[0037] A high-strength rigging steel rope for hoisting with an anti-breakage property comprises a hoisting steel rope 1, a steel rope rigging 6 is sleeved on one side of the hoisting steel rope 1, the steel rope rigging 6 comprises a first connecting sleeve 29 and a second connecting sleeve 30, the hoisting steel rope 1 passes through the first connecting sleeve 29 and changes to the second connecting sleeve 30 and is surrounded by a hanging ring, and a heart ring 7 is provided in the hanging ring, a constraint sleeve groove 8 is opened on one side of the first connecting sleeve 29, the diameter of the constraint sleeve groove 8 is larger than the diameter of the hoisting steel rope 1, the end of the hoisting steel rope 1 passes through the constraint sleeve groove 8 of the first connecting sleeve 29, and the hoisting A cast anti-slip block 9 is provided on one side of the steel rope 1 located in the constraint sleeve 8. After the lifting steel rope 1 passes through the constraint sleeve 8 of the first connecting sleeve 29, molten metal is poured into the constraint sleeve 8 with the lifting steel rope 1 through a meltable metal. The molten metal can be an aluminum-tin based babbitt alloy, and a cast anti-slip block 9 is formed after solidification to ensure that the constraint sleeve 8 and the cast anti-slip block 9 cannot break and detach from the first connecting sleeve 29 of the steel rope sling 6. When the constraint sleeve 8 is mixed with the cast anti-slip block 9, the end of the constraint sleeve 8 can disperse the broken strands, so that the monofilament forms a fluffy ball.

[0038] The inner maintenance component is provided to replenish lubricating oil internally for the hoisting steel rope 1 during use, so as to reduce excessive wear between the monofilaments of the hoisting steel rope 1. The hoisting steel rope 1 includes a central maintenance tube 3 and a plurality of winding strands 2. The plurality of winding strands 2 are wound. The central maintenance tube 3 is provided at the center of the plurality of winding strands 2. The central maintenance tube 3 is evenly embedded with a plurality of metal support rings 4. A plurality of oil mist spray holes 5 are connected between two adjacent metal support rings 4 in the winding strands 2. One end of the hoisting steel rope 1 and the central maintenance tube 3 is provided with a protruding cast anti-slip block 9. When the restraining sleeve groove 8 and the cast anti-slip block 9 are combined, the monofilaments of the winding strands 2 need to ensure basic protection of the central maintenance tube 3. At the same time, the central maintenance tube 3 is a composite elastic material that is corrosion-resistant, high-temperature resistant and has a certain strength. The interval setting of the metal support rings 4 can ensure that the central maintenance tube 3 bends along with the hoisting steel rope 1, while the metal support rings 4 can support the wound winding strands 2 to avoid excessive squeezing and deformation of the central maintenance tube 3.

[0039] When the lifting steel rope 1 is in normal use, the heart-shaped ring 7 of the lifting steel rope 1 is connected to the lifting hook. The heart-shaped ring 7 serves as the main wear point of the lifting steel rope 1 to prevent the monofilament of the lifting steel rope 1 from wear and breakage. When the lifting steel rope 1 is used for a long time and the winding rope strands 2 and the internal monofilaments are relatively dry, a high-pressure airflow containing lubricating oil is blown into the central maintenance tube 3 through the end of the central maintenance tube 3. The high-pressure airflow flows in the central maintenance tube 3. At the same time, the high-pressure airflow blows the lubricating oil-containing airflow to the winding rope strands 2 from the inside of the lifting steel rope 1 through a number of oil mist nozzles 5, thereby realizing lubrication of the lifting steel rope 1 from the inside out. Compared with the traditional external lubricating oil application or immersion in lubricating oil, it has the effects of high efficiency and worry-free and convenient operation. In addition, when the central maintenance tube 3 is in use, the two ends can be in a closed and open state. When not in use, both ends can be sealed by rubber caps.

There are bite grooves 24; when the two fixing bolts 16 partially position the two constraint ends 15, one end of the first combined pipe 11 and the second combined pipe 12 has been constrained. At this time, the closing sleeve 19 is sleeved by means of pressure such as hammering. It is connected to the annular structure composed of two arc-shaped combined plates 18. During the press-fitting process, the two arc-shaped combined plates 18 can be quickly docked by abutting the conical guide groove 20 with the conical surface of the arc-shaped combined plate 18. At this time, the closing sleeve 19 and the two fixing bolts 16 respectively constrain the two ends of the junction of the first combined tube 11 and the second combined tube 12. Then the constraining threaded piece 22 is threadedly inserted into the arc-shaped combined groove 17 to push the closing sleeve 19 to limit its position and keep the closing sleeve 19 tightly positioned.
