Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel wire ropes, in particular to a steel wire rope connecting device. Background Technique
[0002] When connecting steel wire ropes, the two ends of the steel wire ropes are fixedly connected through a connecting device, such as using a threaded cylinder, and a hole is opened in the middle of the threaded cylinder. The two ends of the steel wire ropes are respectively inserted into the threaded cylinder from both ends and then pulled out from the hole. Then, two nuts screwed on the threaded cylinder are used to move closer to each other from both sides of the hole to squeeze and clamp the ends of the two steel wire ropes for fixation.
[0003] The above-mentioned fixing method of the steel wire rope is single. Once the nut rotates accidentally, the two steel wire ropes will directly spread apart, lacking an accidental protection structure. Content of the Utility Model
[0004] The utility model aims to solve at least the problem of single fixing means after the butt joint of the steel wire rope in the prior art and the lack of accidental temporary protection.
[0005] This solution provides a steel wire rope connecting device, which is achieved by the following specific technical means: including an external threaded cylinder, a hole is opened in the middle of the external threaded cylinder. The two ends of the steel wire ropes are respectively inserted into the external threaded cylinder from both ends and then pulled out from the hole. Two nuts are sleeved on the external threaded cylinder. Temporary limiting mechanisms are arranged at both ends of the external threaded cylinder. The temporary limiting mechanism includes an installation hole opened in the side wall of the external threaded cylinder near the end part. A connecting shaft is fixed in the installation hole, and a limiting member is rotatably installed on the connecting shaft. One end of the limiting member extends into the inner cavity of the external threaded cylinder, and the other end extends to the outside of the external threaded cylinder. A spring is connected between the outer end of the limiting member and the end of the external threaded cylinder. When the nut approaches the outer end of the limiting member, the inner end of the limiting member is pushed away from the steel wire rope, facilitating the feeding of the steel wire rope. After the end of the steel wire rope is pulled out from the hole, when the two nuts move inwards to clamp the steel wire rope, the limitation on the limiting member is released, so that the inner end of the limiting member contacts the steel wire rope to achieve temporary protection.
[0006] Preferred Technical Solution 1: A plurality of groups of the installation holes are distributed on the circumferential side of the external threaded cylinder, so that the inner ends of the plurality of groups of limiting members at one end of the external threaded cylinder form a limiting clamping opening. When the nut squeezes the outer end of the limiting member to compress the spring, the limiting clamping opening opens. When the nut moves away from the limiting member, the limiting clamping opening closes and surrounds the steel wire rope in contact.
[0007] Preferred Technical Solution 2: An annular seat is fixed at the end of the external threaded cylinder. The side wall of the annular seat surrounds the external threaded cylinder, and at the same time, the spring is located inside the annular seat for protection.
[0008] Preferred Technical Solution 3: An active ring slides within the annular seat. The active ring is slidably sleeved on the external thread cylinder, and both ends of the spring are connected to the end wall of the annular seat and the active ring respectively. The active ring is used to contact the side of multiple limiting members away from the nut simultaneously.
[0009] Preferred Technical Solution 4: The installation hole is located inside the annular seat.
[0010] Preferred Technical Solution 5: When multiple limiting members are in the same plane, the size of the limiting clamp opening is minimized. At this time, the size of the enclosed limiting clamp opening is smaller than the diameter of the wire rope.
[0011] Adopting the above structure enables this solution to have the following beneficial effects:
[0012] 1. When the nut rotates accidentally and the clamping force on the wire rope disappears, it can temporarily limit the pre-dispersed wire rope, preventing the wire rope from directly coming loose and affecting the use safety.
[0013] 2. The nut and the temporary limiting mechanism can be interlocked with each other. When the wire rope is fed in, the opening of the limiting clamp opening can be controlled by the nut, and when the nut completes the clamping of the wire rope, the working state of the temporary limiting mechanism can be automatically turned on.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1-5 , a wire rope connection device, including an external thread cylinder 1. A hole 11 is provided in the middle of the external thread cylinder 1. Two groups of wire rope ends respectively extend into the external thread cylinder 1 from both ends and are pulled out from the hole 11. Two groups of nuts 2 are sleeved on the external thread cylinder 1. The two groups of nuts 2 approach each other from both sides of the opening to squeeze and clamp the ends of the two groups of wire ropes for fixation;
[0023] Temporary limiting mechanisms 3 are provided at both ends of the external thread cylinder 1. The temporary limiting mechanism 3 includes a mounting hole 31 provided in the side wall of the external thread cylinder 1 near the end part. A connecting shaft 32 is fixed in the mounting hole 31, and a limiting member 33 is rotatably mounted on the connecting shaft 32. One end of the limiting member 33 extends into the inner cavity of the external thread cylinder 1, and the other end extends to the outside of the external thread cylinder 1. A spring 34 is connected between the outer end of the limiting member 33 and the end of the external thread cylinder 1. The spring 34 is used to push the outer end of the limiting member 33 to swing towards the middle of the external thread cylinder 1, so that the inner end of the limiting member 33 swings towards the port direction. One group of nuts 2 contacts the side of the limiting member 33 close to the middle of the external thread cylinder 1. When feeding the wire rope, the nut 2 is at a position far from the hole 11 to squeeze the outer end of the limiting member 33 to compress the spring 34 and swing towards the port, so that the inner end of the limiting member 33 swings towards the middle of the external thread cylinder 1, facilitating the feeding of the wire rope. After the wire rope end is pulled out from the hole 11, when the nut 2 is screwed in to clamp the wire rope, the limitation on the limiting member 33 is released, so that the inner end of the limiting member 33 swings close to the wire rope and contacts the wire rope.
[0024] Please refer to Figures 1-5 , a wire rope connection device. A plurality of groups of mounting holes 31 are distributed on the circumferential side of the external thread cylinder 1, so that the inner ends of the plurality of groups of limiting members 33 at one end of the external thread cylinder 1 enclose a limiting clamp opening 35. When the nut 2 squeezes the outer end of the limiting member 33 to compress the spring 34, the limiting clamp opening 35 is opened. When the nut 2 is far from the limiting member 33, the limiting clamp opening 35 is closed and surrounds the wire rope in contact. When the nut 2 is accidentally loosened, the wire rope loosens and moves outwards. Then, because the wire rope contacts the ends of the plurality of groups of limiting members 33, it will drive the limiting members 33 to further press on the wire rope, increasing the frictional resistance and preventing the wire rope from directly coming out of the external thread cylinder 1, realizing temporary protection; when the plurality of groups of limiting members 33 are in the same plane, the size of the limiting clamp opening 35 is the smallest, and the size of the enclosed limiting clamp opening 35 is smaller than the diameter of the wire rope.
[0025] Please refer to Figures 1-4 , for a wire rope connecting device, an annular seat 36 is fixed at the end of the external thread cylinder 1. The side wall of the annular seat 36 surrounds the external thread cylinder 1. Meanwhile, a spring 34 is located inside the annular seat 36 for protection. A movable ring 37 slides inside the annular seat 36. The movable ring 37 is slidably sleeved on the external thread cylinder 1. Both ends of the spring 34 are respectively connected to the end wall of the annular seat 36 and the movable ring 37. By using the movable ring 37 to simultaneously contact the sides of multiple limit members 33 away from the nut 2, the technical effect of providing elastic support to multiple limit members 33 by one spring 34 is achieved.
[0026] Please refer to Figure 2 and Figure 5 , for a wire rope connecting device, an insertion cylinder 21 is fixed on the side of the nut 2 away from the hole 11. The insertion cylinder 21 surrounds the external thread cylinder 1. And when the nut 2 approaches the corresponding limit members 33, the ports of the insertion cylinder 21 simultaneously contact the outer ends of multiple limit members 33. The installation hole 31 is located inside the annular seat 36. When the insertion cylinder 21 is inserted into the annular seat 36, it contacts the limit members 33.
[0027] Please refer to Figure 5 , for a wire rope connecting device, an anti-slip layer is provided on the opposite side of the nut 2, and the anti-slip layer is used to contact the wire rope.
