Description

Technical Field

[0001] This utility model relates to the field of wire rope locking technology, specifically to a quick-locking device for wire rope. Background Technology

[0002] Currently, various metal protective nets and barriers formed by connecting steel wire ropes between two upright posts are widely used for protection due to their ease of installation and good impact resistance. During installation, these metal protective nets and barriers require the use of a quick-locking device to connect and tighten the steel wire ropes, applying a certain pre-tension. Existing quick-locking devices consist of an adjusting screw, a variable-diameter spring, a locking sleeve, steel balls, and a locking sleeve. In use, the locking sleeve is pressed upwards. The contraction of the variable diameter spring reduces the contact strength between the hollow frustum of the locking sleeve and the conical hole of the locking sleeve, thus decreasing the clamping strength of the steel ball. When the locking sleeve is released, the variable diameter spring expands, restricting the free rolling of the steel ball and increasing the clamping strength. However, the existing quick-locking device for steel wire ropes has the following shortcomings: the steel ball is limited by the contact between the inclined surfaces of the hollow frustum of the locking sleeve and the conical hole of the locking sleeve. The squeezing distance of the steel ball is small, and it cannot ensure that multiple steel balls can be tangent to each other, which limits the size of the steel wire rope that can be used. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a wire rope quick locking device that can achieve rapid locking of wire rope, and the contact between the inner truncated cone and the steel ball is the inclined surface of the inner truncated cone and the spherical surface of the steel ball. The clamping stroke range between multiple steel balls is larger, and it can ensure that multiple steel balls are tangent to optimize the minimum outer diameter of the lockable wire rope, so as to be compatible with more wire ropes with a wider outer diameter.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A wire rope quick locking device includes a limiting rod, a frustum cylinder, steel balls, a spring, and a spring limiting mechanism. The frustum cylinder has a frustum cavity extending through both ends. The limiting rod is coaxially arranged with the frustum cylinder and is sleeved in the frustum cavity, allowing relative axial movement. The limiting rod has a rope-passing channel extending through both ends. The outer circumferential surface of the limiting rod has multiple limiting holes evenly arranged along its circumferential direction and communicating with the rope-passing channel. The limiting holes contain matching and movable steel balls. The spring limiting mechanism is located on the side of the frustum cylinder with a large opening. The spring is located between the spring limiting mechanism and the limiting rod and is used to always apply an elastic force to the limiting rod, pushing multiple steel balls to move towards the narrow end of the frustum cavity and, with the cooperation of the inner frustum surface of the frustum cavity, causing multiple steel balls to move synchronously towards the central axis of the rope-passing channel.

[0005] Furthermore, the outer diameter of the steel ball is not less than the inner diameter of the rope-threading channel.

[0006] Furthermore, an annular protrusion for abutting against the spring is fixed on the outer circumferential surface of the limiting rod.

[0007] Furthermore, when all the steel balls inside the limiting rod are tangent to each other, the diameter of the outer tangent circle that is tangent to all the steel balls is greater than the maximum outer diameter of the limiting rod.

[0008] Furthermore, the spring limiting mechanism includes a limiting sleeve, which has a limiting cavity that is open at one end and adapted to the frustum cylinder. The limiting sleeve is fitted onto the outside of the frustum cylinder through the limiting cavity and the two are fixedly connected. The other end face of the limiting sleeve has a through hole that communicates with the limiting cavity and is located on the side of the frustum cylinder with a large opening. One end of the limiting rod is adapted to the through hole and extends outward and passes through the through hole.

[0009] Furthermore, the other end of the limiting rod extends outward and passes through the side of the frustum-shaped cylinder with a small opening.

[0010] Furthermore, a snap-fit ​​assembly is provided between the limiting sleeve and the frustum cylinder. The snap-fit ​​assembly includes matching slots and blocks. Multiple slots are provided on the outer circumferential surface of the open end of the limiting sleeve, and multiple blocks are fixedly provided on the outer circumferential surface of the end with the small opening on the frustum cylinder. The multiple blocks correspond one-to-one with the multiple slots and snap-fit ​​together.

[0011] Furthermore, the spring limiting mechanism includes a fixed limiting plate, which is spaced apart from the frustum cylinder. The limiting plate has an insertion hole through which the spring can pass. A limiting cap for abutting against the spring is detachably installed in the insertion hole. The limiting cap has a rope hole that passes through both ends of it.

[0012] Furthermore, the limit cap is threaded into the insertion hole of the limit plate, and a first rotating operation hole is provided on the outer circumferential surface of the limit cap.

[0013] Furthermore, two symmetrically arranged guide blocks are fixedly provided on the outer circumferential surface of the frustum cylinder. A moving drive assembly for moving the frustum cylinder relative to the limiting plate is provided on one side of the frustum cylinder with a small opening. The moving drive assembly includes a driving outer sleeve and a driving inner sleeve. The driving outer sleeve has a first inner cavity that passes through both ends and allows the limiting rod to pass through. The driving inner sleeve has a second inner cavity that passes through both ends and allows the limiting rod to pass through. The driving outer sleeve is stepped and includes a large sleeve and a small sleeve that are fixedly connected in sequence. One end of the driving inner sleeve is fixedly connected to the end of the frustum cylinder with a small opening. The large sleeve is sleeved on the outside of the driving inner sleeve and the two are threaded together. A second rotating operating hole is provided on the outer circumferential surface of the small sleeve. One end of the limiting post extends outward into the small sleeve.

[0014] As described above, the wire rope quick-locking device provided by this utility model has the following beneficial effects: By providing multiple limiting holes on the limiting rod, it is convenient to place multiple steel balls inside the limiting rod, and a clamping cavity for clamping the wire rope is formed between the multiple steel balls. The spring limiting mechanism facilitates the stable installation of the spring between the spring limiting mechanism and the limiting rod, maintaining a certain elastic force on the limiting rod. Simultaneously, in conjunction with the use of a frustum cylinder, a frustum cavity with a large opening at one end and a small opening at the other is provided, forming an inner frustum surface. The inner diameter of the frustum cavity gradually decreases. Thus, under the elastic force maintained by the spring on the limiting rod, multiple steel balls can be pushed... Each steel ball moves towards the narrow end of the frustum cavity, and with the cooperation of the inner frustum surface, the multiple steel balls move synchronously towards the central axis of the rope threading channel, thereby increasing the clamping strength of the steel balls on the wire rope and achieving rapid locking of the wire rope. The contact between the frustum cylinder and the steel balls is achieved by the inclined surface of the inner frustum surface and the spherical surface of the steel balls, which directly limits the movement of the steel balls and increases the clamping stroke range between the multiple steel balls. It also ensures that the multiple steel balls are tangent to each other. When the multiple steel balls are tangent, the outer diameter of the clamping cavity formed between the multiple steel balls is the smallest, which optimizes the minimum diameter of the lockable wire rope and can accommodate more wire ropes with different outer diameters.

Detailed Implementation

[0026] The present invention will be further described below through specific embodiments. Example

[0027] like Figures 1 to 6 As shown, the present invention provides a quick-locking device for steel wire rope, comprising a limiting rod 1, a frustum cylinder 2, steel balls 3, a spring 4, and a spring limiting mechanism 5. The frustum cylinder 2 has a frustum cavity 21 extending through both ends. The limiting rod 1 is coaxially arranged with the frustum cylinder 2 and is axially movable relative to it, fitted within the frustum cavity 21. The limiting rod 1 has a rope-passing channel 11 extending through both ends. The outer circumferential surface of the limiting rod 1 has multiple limiting holes 12 evenly arranged along its circumference and communicating with the rope-passing channel 11. The limiting hole 12 contains a matching and movable steel ball 3. The spring limiting mechanism 5 is located on the side of the frustum cylinder 2 with a large opening. The spring 4 is located between the spring limiting mechanism 5 and the limiting rod 1 and is used to apply an elastic force to the limiting rod 1 at all times, which pushes the multiple steel balls 3 to move toward the narrow end of the frustum cavity 21 and, with the cooperation of the inner frustum surface 211 of the frustum cavity 21, makes the multiple steel balls 3 move synchronously toward the central axis of the rope channel 11.

[0028] The rope-passing channel 11 on the limiting rod 1 allows the steel wire rope 7 to pass smoothly through. Multiple limiting holes 12 are provided on the limiting rod 1, facilitating the placement of multiple steel balls 3 within the limiting rod 1. Clamping cavities for holding the steel wire rope 7 are formed between the multiple steel balls 3. The spring limiting mechanism 5 ensures that the spring 4 is stably installed between the spring limiting mechanism 5 and the limiting rod 1, maintaining a certain elastic force on the limiting rod 1. Simultaneously, in conjunction with the use of the frustum cylinder 2, a frustum cavity 21 with one large opening and one small opening is provided, forming an inner frustum surface 211. The inner diameter of the frustum cavity 21 gradually decreases. Thus, under the elastic force maintained by the spring 4 on the limiting rod 1, multiple steel balls 3 can be pushed towards the limiting rod 1. The narrow end of the frustum cavity 21 moves and, with the cooperation of the inner frustum surface 211 of the frustum cavity 21, the multiple steel balls 3 move synchronously toward one side of the central axis of the rope passage 11, thereby increasing the clamping strength of the multiple steel balls 3 on the wire rope 7, so as to achieve rapid locking of the wire rope 7. Moreover, the contact between the frustum cylinder 2 and the steel balls 3 is the inclined surface of the inner frustum surface 211 and the spherical surface of the steel ball 3, so as to directly limit the steel balls 3, which is beneficial to increase the compression movement distance of the steel balls 3, thereby increasing the clamping stroke range between the multiple steel balls 3, and ensuring that the multiple steel balls 3 can be tangent. When the multiple steel balls 3 are tangent, the outer diameter of the clamping cavity formed between the multiple steel balls 3 is the smallest, so as to optimize the minimum diameter that can lock the wire rope 7, and can adapt to more outer diameter sizes of wire rope 7.

[0029] Preferably, the outer diameter of the steel ball 3 is not less than the inner diameter of the rope channel 11, which helps to simplify the assembly process and prevents the steel ball 3 from easily falling out of the rope channel 11 of the limiting rod 1 during assembly or use.

[0030] In addition, an annular protrusion 13 is fixedly provided on the outer peripheral surface of the limiting rod 1 for abutting against the spring 4, so as to ensure stable abutment between the spring 4 and the limiting rod 1, and so that the spring 4 can maintain applying a corresponding elastic force to the limiting rod 1.

[0031] When all the steel balls 3 inside the limiting rod 1 are tangent to each other, the diameter of the outer tangent circle that is tangent to all the steel balls 3 is greater than the maximum outer diameter of the limiting rod 1. At this time, the limiting rod 1 cannot continue to move relative to the inner sleeve, and can be adapted to the use of steel wire ropes 7 with more outer diameters. Correspondingly, the outer diameter of the steel ball 3 is greater than the depth of the limiting hole 12.

[0032] Preferably, the number of limiting holes 12 is 2-4, and correspondingly, the number of steel balls 3 is also 2-4.

[0033] The spring limiting mechanism 5 includes a limiting sleeve 51. The limiting sleeve 51 has a limiting cavity 511 that is open at one end and adapted to the frustum cylinder 2. The limiting sleeve 51 is sleeved on the outside of the frustum cylinder 2 through the limiting cavity 511 and the two are fixedly connected. Preferably, the limiting sleeve 51 and the frustum cylinder 2 are locked and fixed by a locking screw 53, which makes the installation simpler. The other end face of the limiting sleeve 51 has a through hole 512 that communicates with the limiting cavity 511 and is located on the frustum cylinder 2 with a large opening. One end of the limiting rod 1 is adapted to the through hole 512 and extends outward and passes through the through hole 512. In this embodiment, the limiting sleeve 51 is cylindrical. In other embodiments, the external structure of the limiting sleeve 51 can be changed to cooperate with other accessories, and there are more ways to cooperate.

[0034] Furthermore, the other end of the limiting rod 1 extends outward and passes through the side of the frustum cylinder 2 with a small opening. In use, pressing the limiting rod 1 inward can compress the spring 4, thereby reducing the squeezing strength of the inner frustum surface 211 of the frustum cylinder 2 on the steel balls 3. This reduces the clamping strength of the multiple steel balls 3 on the wire rope 7. When the limiting rod 1 is released, the spring 4 expands, and under the elastic force of the spring 4 expansion, the limiting rod 1 moves outward. As a result, the inner frustum surface 211 of the frustum cylinder 2 restricts the free rolling of the steel balls 3 and squeezes the multiple steel balls 3 to move synchronously toward the central axis of the rope channel 11, thereby increasing the clamping strength of the multiple steel balls 3 on the wire rope 7. This achieves rapid locking of the wire rope 7, allowing the locking operation to be completed in a short time, improving work efficiency, and the locking and releasing operations are simple and convenient.

[0035] In addition, the quick-locking device in this embodiment can be first installed on the support frame 9, and then assembled into the column 8 together with the support frame 9.

[0036] A locking assembly 52 is provided between the limiting sleeve 51 and the frustum cylinder 2. The locking assembly 52 includes matching slots 521 and locking blocks 522. Multiple slots 521 are provided on the outer circumferential surface of the open end of the limiting sleeve 51. Multiple locking blocks 522 are fixedly provided on the outer circumferential surface of the end with a small opening on the frustum cylinder 2. The multiple locking blocks 522 correspond one-to-one with the multiple slots 521 and are locked together. This helps to further improve the stability of the connection between the limiting sleeve 51 and the frustum cylinder 2. Preferably, the number of slots 521 and locking blocks 522 are both 2-4. Example

[0037] like Figures 7 to 10 As shown, the difference between this embodiment and Embodiment 1 is that the spring limiting mechanism 5 includes a fixedly installed limiting plate 54. Correspondingly, in this embodiment, the support frame 9 includes two symmetrically spaced bending brackets, which are connected and fixed by bolt assemblies. The bending brackets are provided with insertion slots, and the limiting plate 54 is installed in the insertion slots of the two bending brackets to achieve relative fixation of the installation position of the limiting plate 54. The limiting plate 54 is spaced apart from the frustum cylinder 2 to ensure that the frustum cylinder 2 has a certain amount of movement space. In addition, the limiting plate 54... The device has an insertion hole 541 through which the spring 4 can pass to facilitate the smooth assembly of the spring 4. A limiting cap 55 for abutting against the spring 4 is detachably installed in the insertion hole 541 to ensure the stability of the spring 4's installation position. The limiting cap 55 has a rope hole 551 through both ends, which allows the wire rope 7 to pass through smoothly. In addition, the rope hole 551 has a conical surface, and one end of the spring 4 can also extend into the rope hole 551 and abut against the conical surface to limit one end of the spring 4.

[0038] Preferably, the limiting cap 55 is threaded into the insertion hole 541 of the limiting plate 54 to facilitate quick assembly and disassembly between the limiting cap 55 and the limiting plate 54. Accordingly, the insertion hole 541 is a threaded hole, and the limiting cap 55 is a limiting nut to facilitate threaded connection between the two. In addition, the outer circumferential surface of the limiting cap 55 is provided with a first rotation operation hole 552, which facilitates the use of a corresponding rotation tool to be inserted into the first rotation operation hole 552 to drive the limiting cap 55 to rotate, thereby tightening or loosening it.

[0039] In addition, two guide blocks 22 are fixedly arranged symmetrically on the outer circumferential surface of the truncated cone 2. Correspondingly, the two bent brackets of the support frame 9 are each provided with a guide groove 91 that is adapted to the guide block 22. The guide groove 91 is elongated. The two guide blocks 22 are respectively engaged in the two guide grooves 91 and slide together to guide the movement of the truncated cone 2 and prevent the truncated cone 2 from rotating. The side of the truncated cone 2 with a small opening is provided with a moving drive assembly 6 for driving the truncated cone 2 to move relative to the limiting plate 54.

[0040] Correspondingly, the moving drive assembly 6 includes a drive outer sleeve 61 and a drive inner sleeve 62. The drive outer sleeve 61 has a first inner cavity that extends through both ends and allows the limiting rod 1 to pass through. The drive inner sleeve 62 has a second inner cavity that extends through both ends and allows the limiting rod 1 to pass through. The drive outer sleeve 61 is stepped and includes a large sleeve 611 and a small sleeve 612 that are fixedly connected in sequence. One end of the drive inner sleeve 62 is fixedly connected to one end of the frustum cylinder 2 with a small opening. The large sleeve 611 is sleeved on the outside of the drive inner sleeve 62 and the two are threaded together. Correspondingly, the inner surface of the large sleeve 611 is provided with an internal thread, and the outer surface of the drive inner sleeve 62 is provided with an external thread to realize the threaded connection between the two. The outer circumferential surface of the small sleeve 612 is provided with a second rotating operating hole 6121, and one end of the limiting post extends outward into the small sleeve 612.

[0041] In this embodiment, the quick-locking device can be first installed between the two bent brackets of the support frame 9, and then assembled into the column 8 together with the support frame 9. Under the elastic force of the spring 4, the drive outer sleeve 61 can abut against the inner surface of the column 8 to keep the relative installation position of the drive outer sleeve 61 unchanged. In use, a corresponding rotating tool can be inserted into the second rotating operation hole 6121 to drive the drive outer sleeve 61 to rotate. Since the installation position of the drive outer sleeve 61 remains relatively unchanged, the threaded connection between the drive outer sleeve 61 and the drive inner sleeve 62, as well as the guiding effect of the guide block 22, allows the drive inner sleeve 62 to move relative to the drive outer sleeve 61. When the drive outer sleeve 61 rotates counterclockwise, the drive inner sleeve 62 moves away from the limiting plate 54 to drive the frustum cylinder 2. Simultaneously, the spring 4 moves away from the limiting plate 54, expanding outward and reducing the compressive strength of the inner truncated cone surface 211 of the truncated cone cylinder 2 on the steel ball 3. This reduces the clamping strength of the multiple steel balls 3 on the wire rope 7. When the driving outer sleeve 61 rotates clockwise, the driving inner sleeve 62 moves closer to the limiting plate 54, causing the truncated cone cylinder 2 to move synchronously closer to the limiting plate 54. At this time, the spring 4 compresses inward, and the inner truncated cone surface 211 of the truncated cone cylinder 2 restricts the free rolling of the steel ball 3, squeezing the multiple steel balls 3 to move synchronously towards the central axis of the rope channel 11. This enhances the clamping strength of the multiple steel balls 3 on the wire rope 7, enabling rapid locking of the wire rope 7. The locking operation can be completed in a short time, improving work efficiency, and the locking and releasing operations are simple and convenient.

[0042] Other technical features are the same as in Embodiment 1.

[0043] It should be understood that during the development of any practical implementation, such as in any engineering or design project, a large number of specific implementation decisions may be made. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing and production without much experimentation.

[0044] The above are only some specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
