Description

Technical Field

[0001] This utility model relates to the field of wire rope technology, and in particular to a protruding annular wire rope sling. Background Technology

[0002] Wire ropes are widely used in hoisting construction. They generally consist of a wire rope body and a ring at one end of the wire rope body, which is secured by a clamp.

[0003] In existing technologies, the fixing clamp is generally a closed loop, fitted onto both ends of the ring. Then, a stamping machine is used to flatten the fixing clamp, clamping it to the inner ring to form an extended annular wire rope sling. While this type of wire rope sling is simple to manufacture, the deformation of the fixing clamp during stamping, and the release of stored elastic strain energy after the stamping pressure is unloaded, can easily cause the fixing clamp to spring back, reducing the clamping effect on the ring and affecting the ring's forming stability. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an extended annular steel wire rope rigging that can effectively prevent the rebound of the fixing clamp and ensure the forming stability of the ring sleeve.

[0005] To solve the above-mentioned technical problems, this utility model provides an extendable annular steel wire rope sling, including a steel wire rope and a fixing clamp. The steel wire rope includes a steel wire rope body and a ring sleeve disposed at one end of the steel wire rope body. The ring sleeve includes a first end and a second end disposed opposite to each other. The first end and the second end are connected and fixed by the fixing clamp. The steel wire rope body is connected to the first end. The fixing clamp includes a top plate, a bottom plate spaced apart from the top plate, and a side plate connecting the top plate and the bottom plate. The first end and the second end are both sandwiched between the top plate and the bottom plate, and the first end and the second end are spaced apart to form a gap. The gap is filled with cast metal, and the cast metal connects the first end, the second end, and the fixing clamp.

[0006] As a preferred improvement, the base plate is divided into a first base plate unit and a second base plate unit, with the first base plate unit and the second base plate unit being spaced apart. The first end is sandwiched between the top plate and the first base plate unit, and the second end is sandwiched between the top plate and the second base plate unit.

[0007] As a preferred improvement, the fixing clamp further includes a flange, which is divided into a first flange unit and a second flange unit. The first flange unit is formed by bending the first base plate unit toward the direction close to the top plate, and the second flange unit is formed by bending the second base plate unit toward the direction close to the top plate. The first end is clamped between the side plate and the first flange unit, and the second end is clamped between the side plate and the second flange unit.

[0008] As a preferred improvement, the top plate, bottom plate, and side plate are integrally formed from metal sheets, the first flange unit is formed by stamping and bending the first bottom plate unit, and the second flange unit is formed by stamping and bending the second bottom plate unit.

[0009] As a preferred improvement, a through hole is provided through the top plate, which communicates with the gap for injecting molten metal into the gap.

[0010] As a preferred improvement, the number of through holes is multiple, and the multiple through holes are arranged at equal intervals along the axial direction of the wire rope body.

[0011] As a preferred improvement, the through hole is located directly above the gap.

[0012] As a preferred improvement, the through hole is also filled with cast metal, and is connected with the cast metal filled in the gap to form an integral whole.

[0013] As a preferred improvement, the inner surface of the fixing clamp is rough, and the outer surface of the flange is also rough.

[0014] This invention creates a gap between the first and second ends of the ring sleeve, and then sets a through hole on the top plate of the fixing clamp. Molten metal is injected into the gap through the through hole. After the molten metal hardens, it can effectively connect the first end, the second end and the fixing clamp, which can effectively avoid the springback problem after the fixing clamp is stamped and ensure the forming stability of the ring sleeve.

[0022] The present invention will be further described below with reference to the accompanying drawings and examples.

[0023] like Figures 1-4 As shown, this embodiment provides an extended annular steel wire rope sling, including a steel wire rope 1 and a fixing clamp 2. The steel wire rope 1 includes a steel wire rope body 11 and a loop 12 disposed at one end of the steel wire rope body 11. The loop 12 includes a first end 121 and a second end 122 disposed opposite to each other. The first end 121 and the second end 122 are connected and fixed by the fixing clamp 2. The steel wire rope body 11 is connected to the first end 121. The fixing clamp 2 includes a top plate 21 and a bottom plate spaced apart from the top plate 21. 22 and a side plate 23 connecting the top plate 21 and the bottom plate 22, the first end 121 and the second end 122 are both sandwiched between the top plate 21 and the bottom plate 22, the first end 121 and the second end 122 form a gap 123, the gap 123 is filled with cast metal 3, the cast metal 3 connects the first end 121, the second end 122 and the fixing clamp 2, which can effectively avoid the springback problem after the fixing clamp 2 is stamped and ensure the forming stability of the ring 12.

[0024] The base plate 22 is divided into a first base plate unit 221 and a second base plate unit 222. The first base plate unit 221 and the second base plate unit 222 are spaced apart. The first end 121 is sandwiched between the top plate 21 and the first base plate unit 221, and the second end 122 is sandwiched between the top plate 21 and the second base plate unit 222.

[0025] The fixing clamp 2 also includes a flange 24, which is divided into a first flange unit 241 and a second flange unit 242. The first flange unit 241 is formed by bending the first base plate unit 221 toward the direction close to the top plate 21, and the second flange unit 242 is formed by bending the second base plate unit 222 toward the direction close to the top plate 21. The first end 121 is sandwiched between the side plate 23 and the first flange unit 221, and the second end 122 is sandwiched between the side plate 23 and the second flange unit 242.

[0026] The top plate 21, bottom plate 22, and side plate 23 are integrally formed from metal sheets. The first flange unit 241 is formed by stamping and bending the first bottom plate unit 221, and the second flange unit 242 is formed by stamping and bending the second bottom plate unit 222. The stamping method of this utility model also differs from the prior art. In the traditional technology, the stamping directly squeezes the top plate 21 and the bottom plate 22, and the side plate 23 is deformed accordingly, which is also the part that generates springback. However, in this utility model, the stamping position is at the edge of the first bottom plate unit 221 and the second bottom plate unit 222, so that they are bent and deformed and respectively abut against the first end 121 and the second end 122. The side plate 23 basically does not deform, reducing the springback force generated by the deformation of the side plate 23. The flange 24 can cooperate with the side plate 23 to clamp the ring 12. In addition, in this utility model, the forming stability of the ring sleeve 12 mainly depends on the cast metal 3, while the flange 24 is formed in the gap 123, which can be well embedded in the cast metal 3, increasing the contact area between the fixing clamp 2 and the cast metal, and forming an integral structure with the cast metal, thus ensuring the structural stability of the fixing clamp 2 itself.

[0027] The first end 121 and the second end 122 are kept apart to form the gap 123. The molten metal can cover the entire longitudinal section of the first end 121 and the second end 122, ensuring the contact area between the cast metal 3 and the first end 121 and the second end 122.

[0028] A through hole 210 is provided on the top plate 21, and the through hole 210 communicates with the gap 123 for injecting molten metal into the gap 123.

[0029] The number of through holes 210 is multiple, and the multiple through holes 210 are arranged at equal intervals along the axial direction of the wire rope body 11 to uniformly inject molten metal into each part of the gap 123. The through holes 210 are located directly above the gap 123 to ensure the uniformity of molten metal injection on both sides of the gap 123.

[0030] The through hole 210 is also filled with cast metal 3, which is connected to the cast metal 123 filled in the gap 123 to form an integral whole. The cast metal 3 filled in the through hole 210 can act as a stud, increasing the contact stability between the cast metal 3 and the fixing clamp 2, so that the cast metal 3 and the ring 12 cannot come out from the openings at both ends of the fixing clamp 2.

[0031] Furthermore, the inner surface of the fixing clamp 3 is rough, and the outer surface of the flange 24 is also rough, in order to increase the contact area with the cast metal 3 and increase the stability of the contact.

[0032] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
