Description

Technical Field

[0001] This invention relates to the field of metal wire technology, and in particular to a novel steel wire rope connector. Background Technology

[0002] As a widely used industrial product, wire ropes usually require end fastening in most cases. There are generally five methods of fastening: casting, pressing, splicing, and using wire rope wedge joints or wire rope clips. The first three are used for permanent fastening, while the latter two are used for easy replacement, such as end fastening of wire ropes for mobile cranes, where one end of the wire rope is connected to the crane boom using wire rope wedge joints. However, when using wedge-shaped joint boxes for wire ropes, it is impossible to fold back the wire rope ends and connect them to other equipment. When using wire rope clips, it is quite difficult to connect two wire ropes, especially when the diameter of the connection end cannot change too much and a large fixing force is required. There are many limitations, see GB / T5976. In particular, the U-bolts of the wire rope clips will cause the wire rope to be flattened.

[0003] In industrial applications, there are many situations where two steel wire ropes need to be connected for use. For example, when temporarily extending two steel wire ropes, or when connecting a steel wire rope into a loop, the outside of the connection point needs to be wrapped with steel wire rope, without too much change, and it needs to be easy to disassemble. In these cases, since the steel wire rope is mainly made of high carbon steel, it will crack after welding. The current practice is to press the two ends together with an aluminum tube. However, a large bulge will appear at the aluminum tube crimping point. If the rope loop needs to pass through a pulley, it will be very difficult to pass smoothly.

[0004] Therefore, there is an urgent need for a new type of flexible wire rope connector to connect two wire ropes and facilitate passage through pulleys. Summary of the Invention

[0005] The purpose of this invention is to provide a novel wire rope connector to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A novel wire rope connector includes two fastening joints and a universal joint connecting the two fastening joints; The fastening joint includes an upper half-plate, a lower half-plate, and auxiliary pressure plates.

The other fastening ear plate is inserted into the opening groove. The other fastening ear plate is fixed to the second connecting part by passing through the first ear hole and the third ear hole with a second pin.

[0011] Furthermore, the end of the second connecting portion near the opening groove is chamfered towards the opening groove.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] The specific implementation method is as follows: like Figures 1-6 As shown, this invention discloses a novel wire rope connector, comprising two fastening joints and a universal joint connecting the two fastening joints. The fastening joint includes an upper half-slab 1, a lower half-slab 2, and auxiliary pressure plates 3. The upper half-slab 1 and the lower half-slab 2 are fixedly connected by the two auxiliary pressure plates 3. The upper half-slab 1 has a first cavity 4 on the side near the lower half-slab 2, and the lower half-slab 2 has a second cavity 5 on the side near the upper half-slab 1. The first cavity 4 and the second cavity 5 are combined to form a receiving cavity for accommodating the end of the wire rope 24. Adjacent upper half-slabs 1 are connected by a universal joint.

[0021] Specifically, the first cavity 4 is a semi-circular arc groove on the inner side of the upper half tile 1, and the second cavity 5 is a semi-circular arc groove on the inner side of the lower half tile 2. The two are combined to form a circular receiving cavity with a diameter that matches the steel wire rope 24.

[0022] The present invention sets up a universal joint to connect two fastening joints, which allows for flexible angle adjustment while connecting the wire rope 24, making it convenient for the wire rope 24 to pass through the pulley; the upper half-plate 1, the lower half-plate 2 and the auxiliary pressure plate 3 are set up to press and fix the wire rope 24, which can effectively fix the wire rope 24 and facilitate disassembly and replacement.

[0023] In this embodiment, an extension 7 is integrally connected to one side of the upper half tile 1 towards the lower half tile 2. An ear plate 8 is fixedly connected to the side of the extension 7 away from the upper half tile 1. A first ear hole 9 is provided on the ear plate 8. Several first fitting grooves 10 are evenly provided on the side of the upper half tile 1.

[0024] In this embodiment, a first groove 11 is provided on the side of the upper half tile 1 near the lower half tile 2, and a first protrusion 12 is provided on the lower half tile 2 to fit into the first groove 11. A second fitting groove 15 corresponding to the first fitting groove 10 is provided on the side of the lower half tile 2. The auxiliary pressing tile 3 is located on one side of the first fitting groove 10 and on the other side of the second fitting groove 15. The auxiliary pressing tile 3 is fixedly connected to both the upper half tile 1 and the lower half tile 2 by fastening screws 16.

[0025] In this embodiment, the ear plate 8 is welded to the middle position of the extension 7, and one half of the end face of the ear plate 8 is welded and fixed to the extension 7, while the other half of the end face of the ear plate 8 is welded and fixed to the upper half tile 1.

[0026] In this embodiment, the first groove 11 is disposed near the extension 7, and the second protrusion 14 is disposed near the first groove 11.

[0027] The present invention provides an extension 7 to facilitate the welding of the ear plate 8 to the middle position of the extension 7, avoiding the ear plate 8 being located at the edge and breaking under tension. The lower half tile 2 and the upper half tile 1 are positioned by the cooperation of the first groove 11 and the first protrusion 12, and then the auxiliary pressure tile 3 is set in the first fitting groove 10 and the second fitting groove 15. The upper half tile 1 and the lower half tile 2 are fixed by screws to prevent the upper and lower half tiles 2 from lateral displacement during use, which would cause the wire rope 24 to loosen.

[0028] In this embodiment, a second groove 13 is provided on the side of the lower half-tile 2 near the upper half-tile 1, and a second protrusion 14 is provided on the upper half-tile 1 to fit into the second groove 13. The upper half-tile 1 and the lower half-tile 2 are further positioned and fixed by the second groove 13 and the second protrusion 14 to prevent displacement after the upper half-tile 1 and the lower half-tile 2 are connected, which could cause the wire rope 24 to loosen and cause an accident.

[0029] In this embodiment, the universal joint includes a first connecting part 19 and a second connecting part 20. One end of the first connecting part 19 is integrally connected to one end of the second connecting part 20. A second ear hole 21 is provided on the first connecting part 19. An opening groove 23 is provided on the side of the second connecting part 20 away from the first connecting part 19 towards the first connecting part 19. A third ear hole 22 is provided on the second connecting part 20 along the direction perpendicular to the opening groove 23. One of the fastened ear plates 8 is fixed to the first connecting part 19 by a first pin passing through the first ear hole 9 and the second ear hole 21. The other fastened ear plate 8 is inserted into the opening groove 23. The other fastened ear plate 8 is fixed to the second connecting part 20 by a second pin passing through the first ear hole 9 and the third ear hole 22.

[0030] In this invention, the lug hole of one fastening joint corresponds to the positioning hole and is fixed by a pin, so that the universal joint and the fastening joint can change angles around the first pin. The lug plate 8 of the other fastening joint is inserted into the opening groove 23 and fixed by a pin, so that the universal joint and the fastening joint can change angles around the second pin. The first pin and the second pin are perpendicular, so the two fastening joints can change angles in both the horizontal and vertical directions, which is convenient for bending and turning. When passing through the pulley, the angle can be flexibly changed as it moves, so that the connection of the wire rope 24 can pass smoothly through the pulley.

[0031] In this embodiment, the end of the second connecting portion 20 near the opening groove 23 is chamfered at 45° towards the opening groove 23.

[0032] Since the second connecting part 20 abuts against the upper half tile 1 and the extension part 7, when the ear plate 8 and the second connecting part 20 rotate relative to each other, the end of the second connecting part 20 will collide with the upper half tile 1 and the extension part 7, making the rotation inflexible. The present invention makes a chamfered treatment so that when the ear plate 8 and the second connecting part 20 rotate relative to each other, the second connecting part 20 will not affect its rotation, making the angle change more flexible.

[0033] In this embodiment, spiral grooves 6 for fitting steel wire rope 24 are provided on the inner surfaces of both the upper half-tile 1 and the lower half-tile 2.

[0034] The present invention provides a spiral groove 6 so that after the end of the wire rope 24 extends into the receiving cavity, its spiral outer surface can completely fit the groove, increasing the contact area between the wire rope 24 and the upper half tile 1 and the lower half tile 2, increasing the friction, preventing slippage, and making the wire rope 24 more firmly fixed.

[0035] In this embodiment, four clamping grooves 17 are provided on both the upper half tile 1 and the lower half tile 2, and each clamping groove 17 is provided with a clamping screw 18.

[0036] When the clamping screw 18 of the present invention is tightened along the axial direction of the clamping groove 17, the pressure can be directly applied to the steel wire rope 24 in the receiving cavity to clamp and fix the steel wire rope 24, thereby better fixing the steel wire rope 24 and improving the stability of the steel wire rope 24.

[0037] In this embodiment, the wire rope 24 is made of multiple strands of steel wires braided together. Preferably, the wire rope 24 is a 6-strand or 8-strand wire rope 24, which is spiral in shape and corresponds to and fits the spiral groove 6. After the clamping screw 18 clamps the wire rope 24, the spiral of the wire rope 24 increases the frictional tension and keeps the wire rope 24 intact.

[0038] In this invention, the specifications of the spiral groove 6 are different according to the different specifications of the wire rope 24. Each spiral groove 6 corresponds to a different specification of the wire rope 24. Specifically, the spiral groove 6 is set on the inner wall of the first cavity 4 and the second cavity 5. Its pitch and spiral direction are consistent with the braiding pitch and spiral direction of the wire rope 24, ensuring that the wire rope 24 is completely fitted to the inner wall of the cavity after being embedded.

[0039] The present invention utilizes the above-mentioned novel steel wire rope connecting joint to connect steel wire rope 24 in the following manner: First, select upper half-strip 1 and lower half-strip 2 that are compatible with the specifications of steel wire rope 24. Place the end of steel wire rope 24 into the second cavity 5 of lower half-strip 2, fitting it against the spiral groove 6 of lower half-strip 2. Then, fit the first groove 11 and second protrusion 14 of upper half-strip 1 into the first protrusion 12 and second groove 13 of lower half-strip 2, bringing upper half-strip 1 and lower half-strip 2 together. Place the auxiliary pressure plate 3 into the first fitting groove 10 and the second fitting groove 10. At groove 15, the auxiliary pressure plate 3 is screwed into the upper half plate 1, the auxiliary pressure plate 3 and the lower half plate 2 by fastening screw 16, and tightened to fix the upper half plate 1 and the lower half plate 2. Then, the corresponding clamping screw 18 is screwed into the clamping groove 17 to tighten the wire rope 24. Repeat the above steps to fix the end of the other wire rope 24 to the other fastening knot. Then, the ear plates 8 of the two fastening knots are fixed to the first connecting part 19 and the second connecting part 20 of the universal joint by the first pin and the second pin, respectively, to complete the connection of the two wire ropes.

[0040] This invention enables the extension of two steel wire ropes 24 by joining, and can also connect one steel wire rope 24 into a ring; it can be reused, is simple and convenient, the steel wire ropes 24 are not overlapping, have a small diameter, will not bulge again, and are easy to use.
