Description

Technical Field

[0001] This utility model relates to the field of wire rope end fixing technology, specifically a wire rope end fixing device. Background Technology

[0002] The existing method of securing wire rope ends involves binding two strands of wire rope together with a U-shaped clamp, which causes significant damage to the wire rope. Furthermore, existing wire rope end clips are cumbersome to operate and do not provide a secure binding. This does not meet the requirements for a simple and reliable wire rope end clip.

[0003] Utility model CN215370786U discloses a wire rope end binding and fixing device, relating to the technical field of wire rope binding auxiliary equipment, and particularly to a quick wire rope end binding and fixing device. This utility model includes: a compression core rod, a wire rope clip outer sleeve, and a locking and fixing structure; the wire rope clip outer sleeve has through holes machined inside; the locking and fixing structure is installed at one end of the compression core rod; the compression core rod is installed in the wire rope clip outer sleeve and locked by the locking and fixing structure; the two ends of the wire rope are placed at the two ends of the compression core rod and inserted into the wire rope clip outer sleeve along with the compression core rod, and the locking and fixing structure secures the two ends of the wire rope against the wire rope end binding and fixing device. The technical solution of this utility model solves the problems of existing U-shaped clips for binding wire rope ends, such as cumbersome operation, unreliable binding, and significant damage to the wire rope.

[0004] However, the above-mentioned existing technology still has shortcomings in use: the wire rope is pressed into the through hole inside the clamp jacket by the extrusion core rod to achieve the binding and fixation of the rope end, but due to the increased hardness of the wire rope, it is easy to slip under force, so there is a hidden danger of slippage under force and insufficient safety.

[0005] Therefore, this utility model provides a wire rope end fixing device. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wire rope end fixing device to solve the problems mentioned in the background technology. Compared with the existing technology, this utility model has the function of further improving the binding friction of the wire rope end, which greatly improves the reliability of binding and fixing.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wire rope end fixing device, comprising a rope body, a clamp sleeve, a tapered pin, a pad, a screw, and a locking nut. The clamp sleeve has a tapered through hole with a taper adapted to the tapered pin. The tapered pin, through the pad, screw, and locking nut, secures the rope body between the tapered pin and the clamp sleeve. A groove is formed on the opposite tapered wall within the tapered through hole. A positioning hole, connecting the tapered through hole and close to the groove, is formed on one side of the clamp sleeve. A limiting shaft is fitted inside the positioning hole. The limiting shaft and the positioning hole are rotatably and detachably connected, and a clearance plane is formed on its outer peripheral wall.

[0008] Furthermore, there are two positioning holes, which are located near the bottom of the clip sleeve, and the two positioning holes are respectively located near the grooves on the two conical walls inside the conical through hole.

[0009] Furthermore, the positioning hole is a round hole that fits with the limiting shaft with a clearance, and a drive sleeve is fixedly connected to one end of the limiting shaft. The axis of the drive sleeve is perpendicular to the axis of the limiting shaft and parallel to the clearance plane.

[0010] Furthermore, the two tapered surfaces of the tapered pin are provided with clearance notches that cooperate with the limiting shaft.

[0011] Furthermore, the tapered pin has a through hole for insertion into the screw, and the pad has a through hole for clearance fit with the screw.

[0012] Furthermore, a gate-shaped plate is welded to one side of the pad, with the top of the gate-shaped plate facing the through hole, and C-shaped clips that engage with the rope are welded to both sides of the gate-shaped plate.

[0013] Furthermore, the locking nut has an external hexagonal structure, and the distance between the two symmetrical planes on it is equal to the distance between the inner sides of the portal plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting positioning holes, grooves, limiting shafts and clearance planes, facilitates bending of local positions on the rope body that is compressed and fixed, thereby greatly improving the friction between the rope body and the tapered through hole. Compared with the prior art, it has the advantages of stronger anti-slip ability and more reliable fastening connection.

[0016] 2. This utility model uses a drive sleeve, which makes it easy to rotate the limiting shaft with the help of external tools, thus saving effort. Moreover, when the two limiting shafts press the rope in the through hole, the drive sleeves on the two limiting shafts are in a coaxial state, which makes it easy to use an external pin to insert the two drive sleeves to lock the limiting shaft, thus ensuring reliable locking.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: a wire rope end fixing device, including a rope body 1, a clamp sleeve 2, a tapered pin 3, a pad 4, a screw 5, and a locking nut 6. The clamp sleeve 2 has a tapered through hole 21 with a taper that matches the tapered pin 3. The tapered pin 3 secures the rope body 1 between the tapered pin 3 and the clamp sleeve 2 through the cooperation of the pad 4, the screw 5, and the locking nut 6. In use, one end of the rope body 1 is passed through the tapered through hole 21, and then the bent end of the rope body 1 is passed back through the tapered through hole 21. The tapered pin 3 is then inserted into the tapered through hole 21 from the bottom of the clamp sleeve 2. When the tapered pin 3 is slid into the tapered through hole 21 to its limit position, the outer tapered surface of the tapered pin 3 and the inner tapered surface of the tapered through hole 21 will squeeze the rope body 1.

[0023] In this technical solution, a groove 22 is provided on the opposite conical wall inside the conical through hole 21. A positioning hole 23 is provided through one side of the clip sleeve 2, which is connected to the conical through hole 21 and close to the groove 22. The groove 22 can be a semi-circular groove structure coaxial with the positioning hole 23. A limiting shaft 7 is sleeved inside the positioning hole 23. The limiting shaft 7 is provided through the positioning hole 23. The limiting shaft 7 and the positioning hole 23 are rotatably and detachably connected and fitted, and a relief plane 71 is provided on its outer peripheral wall. That is to say, the limiting shaft 7 can be pulled out from the positioning hole 23. When in use, when the relief plane 71 and the groove 22 are opposite, the rope 1 will not be squeezed when it is squeezed. When the limiting shaft 7 is rotated 180°, the outer arc surface of the limiting shaft 7 will squeeze the rope 1, and the rope 1 will bend into the groove 22. Therefore, the friction between the rope 1 and the conical pin 3 and the clip sleeve 2 can be further improved, and the anti-slip performance is stronger.

[0024] Furthermore, there are two positioning holes 23, which are located near the bottom of the clip sleeve 2. The two positioning holes 23 are respectively located near the grooves 22 on the two conical walls inside the conical through hole 21. In other words, both ends of the rope 1 passing through the conical through hole 21 will be squeezed and fixed by the corresponding limiting shaft 7.

[0025] In this embodiment, the positioning hole 23 is a round hole that fits with the limiting shaft 7 with a clearance. This arrangement facilitates the insertion and removal of the limiting shaft 7. One end of the limiting shaft 7 is fixedly connected to a drive sleeve 72. The axis of the drive sleeve 72 is perpendicular to the axis of the limiting shaft 7 and perpendicular to the clearance plane 71. The drive sleeve 72 is a pry bar docking sleeve. In use, one end of the pry bar is inserted into the drive sleeve 72, and the limiting shaft 7 can be easily rotated using the lever principle. This has the advantage of making it easier to control the rotation of the limiting shaft 7. Moreover, after the two limiting shafts 7 squeeze and lock the rope 1, the drive sleeves 72 on them are easily in a coaxial state. At this time, when the external pin is inserted into the two drive sleeves 72, it can effectively prevent the limiting shaft 7 from rotating and loosening. The two conical surfaces of the tapered pin 3 are provided with clearance notches 31 that cooperate with the limiting shaft 7. The clearance notches 31 facilitate the insertion of the limiting shaft 7 through the positioning hole 23.

[0026] In this embodiment, a connecting hole 32 is provided through the tapered pin 3 to engage with the screw 5, and a through hole 42 is provided on the pad 4 to engage with the screw 5. In use, one end of the screw 5 is passed through the connecting hole 32, with the larger end of the screw 5 located within the loop formed by the rope 1. Then, the pad 4 and the locking nut 6 are used to drive the tapered pin 3 to press against the outer wall of the rope 1 inside the tapered through hole 21. This method has the advantage of making it more convenient to operate the screw 5.

[0027] Among them, a gate-shaped plate 41 is welded to one side of the pad 4. The top of the gate-shaped plate 41 is opposite to the through hole 42. C-shaped clips 411 that engage with the rope body 1 are welded to both sides of the gate-shaped plate 41. When in use, the C-shaped clips 411 are fastened to the outside of the rope body 1, which has the function of preventing the pad 4 from twisting.

[0028] Furthermore, the locking nut 6 has an external hexagonal structure and the distance between the two symmetrical planes on it is equal to the distance between the inner sides of the door plate 41. This setting has the function of preventing the locking nut 6 from rotating without manual control. In other words, it is only necessary to use a wrench to tighten the large end of the screw 5.

[0029] Working principle: When the tapered pin 3 is inserted into the inner sleeve 2 of the clip, and the rope 1 is in a slightly compressed state, manually insert one end of the limiting shaft 7 into the positioning hole 23, and then insert one end of the pry bar into the drive sleeve 72. Twist the pry bar to make the limiting shaft 7 rotate. When the limiting shaft 7 rotates, the outer arc surface will squeeze the rope 1. With the relief of the groove 22, the rope 1 will bend and knot. Then tighten the screw 5. At this time, the binding and fixing of the wire rope end is completed.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
