Description

Technical Field

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

[0002] Wire ropes have a wide range of applications. During the use of wire ropes, it is usually necessary to set the ends of the wire ropes into ring joints to facilitate connection with external equipment for hoisting or traction.

[0003] Existing wire ropes generally use a pressed joint method. In the manufacturing process of a pressed joint, the end of the wire rope is first bent back and folded against the main body of the wire rope to form a loop. Then, a sleeve is fitted over the joint, and a pressing die is used to apply pressure to the sleeve, pressing the two strands of wire rope together at the joint. After pressing, the sleeve becomes flat, effectively enclosing and constraining the joint, preventing the two strands of wire rope from separating. This method produces a reliable joint connection, but this pressing method relies on a pressing die, therefore the joint needs to be prefabricated before use, limiting the application scenarios of the wire rope. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a wire rope connector that uses assembled connectors to fasten the wire rope end and the wire rope trunk, so that the connector can be made on site during use, eliminating the reliance on the pressing mold and expanding the application scenarios of the wire rope.

[0005] To solve the above-mentioned technical problems, this utility model provides a wire rope connector, including a wire rope end and a wire rope main body. The wire rope end, after being bent back, fits against the wire rope main body, and the bent section forms a loop. The wire rope end and the wire rope main body are fastened together by a connector, which includes a sleeve, wedge blocks, a drive plate, and bolts. A through hole is provided at the center of the sleeve along the axial direction, through which both the wire rope end and the wire rope main body pass. The wedge blocks... There are two wedge blocks. One wedge block has one side attached to the left side wall of the perforation and the other side attached to the end of the wire rope. The other wedge block has one side attached to the right side wall of the perforation and the other side attached to the main body of the wire rope. The drive plate is spaced apart at the bottom end of the sleeve. The bolt connects the drive plate and the sleeve. Tightening the bolt drives the drive plate to move upward, which in turn drives the two wedge blocks to move upward within the perforation, thus clamping the end of the wire rope and the main body of the wire rope.

[0006] Preferably, the cross-section of the perforation is square; the cross-sectional shape of the wedge block is also square, and the cross-sectional area gradually decreases from bottom to top.

[0007] Preferably, of the four sides of the wedge block, the side that contacts the hole wall of the perforation and is away from the wire rope end / steel rope trunk is a wedge-shaped surface, which is inclined relative to the vertical direction, and the remaining sides are vertical planes.

[0008] Preferably, the side of the wedge block away from the wall of the perforation hole is provided with a groove, the cross-section of the groove is semi-circular, and the diameter of the semi-circle is equal to the diameter of the wire rope.

[0009] Preferably, the length of the wedge block is not less than the length of the perforation.

[0010] Preferably, the drive plate is provided with a through hole at the position corresponding to the through hole, for the main body of the wire rope and the end of the wire rope to pass through, and the diameter of the through hole is not less than twice the diameter of the wire rope.

[0011] Preferably, the bolt includes a screw head, a screw, and a nut. The screw head is located below the drive plate. The bottom end of the screw is fixed to the screw head, and the top end passes through the drive plate and the sleeve in sequence to connect with the nut.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0020] The present invention will be further described below with reference to the accompanying drawings and examples.

[0021] like Figures 1-3 As shown, this embodiment provides a wire rope connector, including a wire rope end 10 and a wire rope main body 20. After the wire rope end 10 is bent back, it fits into the wire rope main body 20. The bent section forms a loop for connecting with other external equipment, such as being fitted onto the hook of a crane or traction machine for lifting or traction operations.

[0022] The wire rope end 10 is fastened to the wire rope main body 20 by a connector 30, which includes a sleeve 1, a wedge block 2, a drive plate 3, and a bolt 4.

[0023] A through hole 5 is provided at the center of the sleeve 1. The through hole 5 penetrates the sleeve 1 along the axial direction of the sleeve 1. The cross-section of the through hole 5 is square and the cross-sectional area is equal at all points.

[0024] Both the wire rope end 10 and the wire rope main body 20 pass through the through hole 5. In use, the wire rope end 10 is first completely passed through the through hole 5 from top to bottom, and the wire rope main body 20 is driven to pass through the through hole 5. Then, the wire rope end 10 is bent back so that it passes through the through hole 5 in the opposite direction (from bottom to top) and fits against the wire rope main body 20.

[0025] The wedge block 2 is inserted into the through hole 5 from bottom to top. There are two wedge blocks 2. One wedge block 2 is attached to the left side wall of the through hole 5 on one side and to the end of the wire rope 10 on the other side. The other wedge block 2 is attached to the right side wall of the through hole 5 on one side and to the main body of the wire rope 20 on the other side. The two wedge blocks 2 cooperate to clamp the end of the wire rope 10 and the main body of the wire rope 20.

[0026] The wedge block 2 also has a square cross-sectional shape, with the cross-sectional area gradually decreasing from bottom to top. The cross-sectional shapes of the wedge block 2 and the through hole 5 are matched, both being square, which can restrict the rotation of the wedge block 2 within the through hole 5 and maintain a stable clamping effect. Of the four sides of the wedge block 2, the side that contacts the hole wall of the through hole 5 and is away from the wire rope end 10 / wire rope trunk 20 is a wedge-shaped surface, which is inclined relative to the vertical direction, while the remaining surfaces are vertical planes.

[0027] The movement direction of the wedge block 2 is consistent with the reverse direction of the wire rope end 10, which can effectively prevent the wire rope end 10 from detaching from the through hole 5.

[0028] The wedge block 2 has a groove 6 on its side away from the wall of the through hole 5. The grooves 6 on the two wedge blocks 2 are positioned opposite each other. The cross-section of the groove 6 is semi-circular, and the diameter of the semi-circle is equal to the diameter of the wire rope. The wire rope end 10 and the wire rope main body 20 are respectively engaged in the grooves 6 of the two wedge blocks 2. The groove 6 increases the contact area between the wedge block 2 and the wire rope end 10 and the wire rope main body 20, which can better exert a squeezing effect on the wire rope end 10 and the wire rope main body 20. In addition, the groove 6 can also play a limiting role, restricting the movement of the wire rope end 10 and the wire rope main body 20, and preventing misalignment of the wire rope end 10 and the wire rope main body 20 within the through hole 5, which would affect the stability of the contact.

[0029] The length of the wedge block 2 is not less than the length of the through hole 5, so that the wedge block 2 can completely pass through the through hole 5, ensuring the contact length between the wedge block 2 and the wire rope end 10 and the wire rope main body 20.

[0030] The drive plate 3 is spaced apart at the bottom end of the sleeve 1 and is used to drive the wedge block 2 to move upward within the through hole 5. Specifically, the drive plate 3 is located below the wedge block 2, and the wedge block 2 is supported on the drive plate 3. When the drive plate 3 moves upward, it can drive the wedge block 2 to move upward within the through hole 5. As the cross-sectional area of ​​the wedge block 2 gradually decreases from bottom to top, its width increases within the through hole 5 as it penetrates deeper, gradually increasing the squeezing effect on the wire rope end 10 and the wire rope main body 20, thus locking the wire rope end 10 and the wire rope main body 20 together. By reasonably adjusting the width of the wedge block 2 and the width of the through hole 5, they are matched to ensure a good locking effect.

[0031] The bolt 4 includes a screw head 41, a screw 42, and a nut 43. The screw head 41 is located below the drive plate 3. The bottom end of the screw 42 is fixed to the screw head 41, and the top end passes through the drive plate 3 and the sleeve 1 in sequence and is connected to the nut 3. The screw 42 and the nut 43 are threadedly connected. By screwing the screw 43, the nut 42 is pressed against the drive plate 3, and the drive plate 3 moves towards the sleeve 1, driving the wedge block 2 to move upward in the through hole 5.

[0032] The sleeve 1 is provided with a stroke hole 6 corresponding to the position of the screw 42. The diameter of the stroke hole 6 is larger than the diameter of the screw 42. The screw 42 passes through the stroke hole 6. The stroke hole 6 is spaced apart from the through hole 5, and the axis of the stroke hole 6 is parallel to the axis of the through hole 5.

[0033] It is understood that, in order to allow the wire rope end 10 and the wire rope main 20 to smoothly enter the through hole 5, the drive plate 3 is provided with a through hole 7 at the position corresponding to the through hole 5, through which the wire rope main 20 and the wire rope end 10 pass. The diameter of the through hole 7 is not less than twice the diameter of the wire rope.

[0034] The drive plate 3 has through holes 30 at positions corresponding to the wire rope end 10 and the wire rope main body 20. The diameter of the through holes 30 is not less than twice the diameter of the wire rope.

[0035] In the wire rope connector provided by this utility model, the wire rope end 10 and the wire rope main body 20 are fastened together by a connector 30. The connector 30 is an assembly structure. Before use, only the individual parts need to be carried. During use, the parts can be assembled according to the connection relationship provided in this embodiment. It is quick and convenient to use and is not limited by the pressure mold in the prior art, thus expanding the application scenarios of the wire rope connector.

[0036] 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.
