Description

Technical Field

[0001] The invention belongs to the technical field of steel cable fixing components, and in particular relates to an anti-dropping component for the end of a steel cable. Background Art

[0002] As the demand for slope and tunnel construction continues to penetrate into difficult-to-develop and underdeveloped areas, the existing projects have objectively been faced with increasingly complex and difficult engineering environments and conditions, bringing with them more uncertain engineering problems and disasters.

[0003] Rock collapse, landslide and rockfall are quite sudden and sometimes have great impact energy, which is a huge test for the protective measures taken. Similarly, in indoor impact tests, the accuracy of the research on the impact resistance of the experimental object also depends on whether the experimental object is stable.

[0004] When a protective structure composed of steel cables is used, the stability of the fixed end of the steel cables plays a decisive role in the overall protective effect. The ends of traditional steel cables are usually fixed by fixing buckles. When the steel cables are impacted for a certain period and subjected to high impact, the buckles at the ends of the steel cables are at risk of slipping off. The slipping of the ends of the steel cables will not only cause the overall failure of the protective structure in engineering, but also cause distortion and failure of the test during the experiment, and even cause danger.

[0005] Therefore, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the prior art. Summary of the invention

[0006] The object of the present invention is to provide an anti-slip assembly for the end of a steel cable, so as to solve the technical problem that the end fixing method of the existing steel cable protection structure is easy to loosen and cause the end of the steel cable to slip.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] An anti-drop assembly for the end of a steel cable, comprising:

[0009] An anti-slip body, the anti-slip body having a plurality of channels for the ends of the steel cables to bend and extend through, each of the channels having a tapered section, and the tapered sections of any two adjacent channels are arranged with opposite tapers;

[0010] The locking unit is a conical cylinder structure surrounded by a plurality of arc-shaped petals, the middle of the conical cylinder structure has a through hole for the steel cable to pass through, the conical cylinder structure is arranged in the conical section and slides in the same direction as the conical section, and each locking unit moves along the channel in the direction of radial contraction so that the inner side wall of the conical section presses the arc-shaped petals to lock the steel cable.

[0011] As a further optimized technical solution, an elastic ring is sleeved on the outer side of the locking unit to maintain the integrity of the conical cylinder structure.

[0012] As a further optimized technical solution, a fixing groove is circumferentially arranged on the outer side wall of the conical cylinder structure, and the elastic ring is arranged in the fixing groove.

[0013] As a further optimized technical solution, a limit block is arranged on the outer side wall of each arc-shaped petal, and a guide groove extending along the direction of the busbar of the tapered section is arranged on the inner side wall of the channel at the position corresponding to the limit block, the cross-section of the guide groove is adapted to the cross-section of the limit block, the limit block is arranged in the guide groove and slidingly cooperates with the guide groove, and the locking unit moves in the radially increasing direction along the channel to expand the diameter of the through hole to facilitate the insertion of the steel cable.

[0014] As a further optimized technical solution, the limiting block includes a connecting section and a limiting section that are integrally connected, and the width of the limiting section is greater than the width of the connecting section.

[0015] As a further optimized technical solution, an elastic driving member is arranged in the channel, and the elastic driving member is arranged on one side of the large diameter end of the conical cylinder structure, and is used to press the locking unit so that the locking unit is automatically locked.

[0016] As a further optimized technical solution, the elastic driving member is a coil spring.

[0017] As a further optimized technical solution, the channel also has an equal diameter section connected to the conical section, the equal diameter section is arranged at the small diameter end of the conical section, and the diameter of the equal diameter section is the same as the diameter of the small diameter end of the conical section.

[0018] As a further optimized technical solution, a baffle is provided at one end of each channel away from the equal-diameter section, and the baffle is used to prevent the locking unit from escaping from the channel. The baffle has a through hole for the steel cable to pass through.

[0019] As a further optimized technical solution, the fixing groove is arranged on a side close to the large diameter end.

[0020] Beneficial effect: By using the technical solution of the present invention, when fixing the rope, the end of the rope is bent and extended to pass through the locking units of the conical tube structure in multiple channels at the same time. When the rope is tightened, each section of the rope passing through a channel drives the locking unit to move along the channel in the direction of radial contraction, so that the conical section of the channel squeezes the arc-shaped petal, and then the rope is locked. The greater the tension on the rope, the tighter the arc-shaped petal is squeezed, so that the rope is locked tighter. In this way, during specific use, the risk of slipping of the end of the steel cable is effectively reduced, and the stability of the protective structure is ensured.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention belong to the scope of protection of the present invention.

They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention. The terms "connected" and "connected" used in the present invention should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0031] The present invention provides an anti-slip assembly for the end of a steel cable. A plurality of channels are opened on an anti-slip body, and locking units are installed in the channels. The locking units cooperate with the channels to lock the steel cable when the steel cable is tightened. The greater the degree of tightening of the steel cable, the more firmly the steel cable is locked, thereby ensuring that the steel cable is not prone to slipping.

[0032] Example 1

[0033] like Figure 1-5 For details, please refer to Figure 2 The anti-drop assembly for the end of the steel cable includes an anti-drop body 1 fixed on the steel cable 4 and a locking unit 3.

[0034] The anti-drop body 1 is assembled from two blocks. Specifically, multiple groups of mounting holes for bolts 7 to pass through are processed on the two blocks. When assembling, the two blocks are assembled together by using nuts 8 to cooperate with the bolts 7 after the bolts 7 pass through the mounting holes. During the assembly process, in order to ensure the accuracy of the two blocks when docking, two trapezoidal positioning blocks 10 are provided on one of the blocks, and correspondingly, two positioning grooves adapted to the positioning blocks 10 are provided on the other block. The positioning blocks 10 cooperate with the positioning grooves to enable the two blocks to be accurately assembled together.

[0035] A plurality of grooves with a semicircular cross section and running through the ends are respectively provided on the opposite sides of the two blocks. After the two blocks are assembled, the plurality of grooves are assembled in pairs to form a channel 2 for the steel cable 4 to pass through. Each channel 2 has a tapered section 201, and the tapered sections 201 of any two adjacent channels 2 are arranged with opposite tapers. In this embodiment, two channels 2 are provided, and after the end of the steel cable 4 passes through one channel 2, it will bend and extend on the side of the channel 2 to pass back into the other channel 2. In other implementations, there may be more than two channels 2, so that when the steel cable 4 is fixed, the end bends and extends through all channels 2.

[0036] Please refer to Figure 2 , Figure 4 The locking unit 3 is a conical cylinder structure surrounded by a plurality of arc-shaped petals 301. The middle of the conical cylinder structure has a through hole 302 for the steel cable 4 to pass through. The conical cylinder structure is arranged in the conical section 201 and is slidably arranged in the same direction as the conical section 201. It should be noted here that the conical cylinder structure and the conical section 201 are in the same direction, which means that the conical setting direction of the conical cylinder structure is the same as the conical setting direction of the conical section 201, so that when the conical cylinder structure slides in the conical section 201, the steel cable 4 can be loosened or locked. Specifically, when each locking unit 3 moves along the channel 2 in the direction of radial contraction, the inner side wall of the conical section 201 will press the arc-shaped petals 301, thereby locking the steel cable 4. Otherwise, it is used to remove the steel cable 4.

[0037] In order to ensure the integrity of the tapered tube structure, an elastic ring 303 is sleeved on the outside of the locking unit 3. Specifically, a circumferentially arranged arc groove is opened at the same position of each arc-shaped petal 301, and all the arc grooves together enclose a circumferentially arranged annular fixing groove 304 on the outer wall of the tapered tube structure. The elastic ring 303 is installed in the fixing groove 304, thereby ensuring that the position of the elastic ring 303 is fixed and it is not easy to slide off when the arc-shaped petals 301 are relatively opened and closed.

[0038] Further, a limit block 305 is provided on the outer wall of each arc-shaped petal 301, and a guide slot 306 extending along the generatrix direction of the tapered section 201 is provided on the inner wall of the channel 2 at the position corresponding to the limit block 305, and the cross section of the guide slot 306 is adapted to the cross section of the limit block 305, and the limit block 305 is arranged in the guide slot 306 and slidably cooperates with the guide slot 306, so that when the locking unit 3 moves in the radially increasing direction along the channel 2, the circumferential spacing between each arc-shaped petal 301 can be increased by the action of the guide slot 306, so that the diameter of the through hole 302 is enlarged, that is, the diameter of the through hole 302 can be enlarged to facilitate the insertion of the steel cable 4. In this embodiment, in order to ensure the matching effect between the locking unit 3 and the tapered section 201, the taper of the locking unit 3 is processed to be the same as the taper of the tapered section 201.

[0039] Please refer to Figure 5 The limiting block 305 includes a connecting section 3051 and a limiting section 3052 which are integrally connected, and the width of the limiting section 3052 is greater than the width of the connecting section 3051. In this way, the limiting section 3052 will be stuck in the guide slot 306, and the locking unit 3 can ensure that the arc-shaped petal 301 does not disengage from the inner side wall of the tapered section 201 when sliding along the tapered section 201.

[0040] Please refer to Figure 2 , Figure 3 A coil spring is provided in the channel 2 as an elastic driving member 5, and the elastic driving member 5 is provided at one side of the large diameter end of the conical cylinder structure, and is used to press the locking unit 3 so that the locking unit 3 is automatically locked. In this way, in a normal state, the locking unit 3 is in an automatically locked state.

[0041] Furthermore, each channel 2 is provided with a baffle 6 at one end away from the equal diameter section 202. The baffle 6 is installed at the end of the channel 2 by means of screws 9. The baffle 6 is used to prevent the locking unit 3 from escaping from the channel 2. The baffle 6 has a through hole 601 for the steel cable 4 to pass through. In this embodiment, the elastic driving member 5 is installed on the side of the large diameter end of the conical cylinder structure. Therefore, the baffle 6 is also used to compress the elastic driving member 5.

[0042] Furthermore, the channel 2 also has a constant diameter section 202 connected to the tapered section 201, and the constant diameter section 202 is arranged at the small diameter end of the tapered section 201, and the diameter of the constant diameter section 202 is the same as the diameter of the small diameter end of the tapered section 201. In this way, when the steel cable 4 is fixed, the constant diameter section 202 has a guiding function, guiding the steel cable 4 to pass into the locking unit 3.

[0043] Furthermore, in order to make it easier to push the locking unit 3 to slide along the guide groove 306 when installing the steel cable 4, the fixing groove 304 is arranged on a side close to the large diameter end.

[0044] Furthermore, in order to more accurately install the steel cable 4 , an installation indicator mark 11 is provided on the surface of the anti-slip body 1 to guide the installation direction of the steel cable 4 .

[0045] Please refer to the Figure 1The present invention selects a suitable model, and it is necessary to ensure that the diameter of the through hole 302 in the unused self-locking state is smaller than the diameter of the steel cable 4. The end of the steel cable 4 has a first fixed section 401 and a second fixed section 402 that are integrally connected, and the second fixed section 402 is close to the end position. When installing the steel cable 4, the second fixed section 402 at the end of the steel cable 4 first penetrates from the bottom of the right channel 2 according to the guidance of the installation indication mark 11. At this time, the end of the steel cable 4 is facing the small diameter end of the locking unit 3. Because the steel cable 4 has a certain rigidity, it will push the locking unit 3 upward to slide upward under the guidance of the equal diameter section 202. During the sliding process, as the limit block 305 and the guide groove 306 cooperate with each other, all the arc petals 301 of the locking unit 3 are separated from each other, and the integrity of the locking unit 3 is maintained under the action of the elastic ring 303. The diameter of the through hole 302 increases accordingly, thereby facilitating the insertion of the steel cable 4. After the second fixed section 402 of the steel cable 4 passes through the channel 2 on the right, the first fixed section 401 finally stays in the channel 2 on the right, and then the steel cable 4 is bent, and the end of the second fixed section 402 is passed from top to bottom into the channel 2 on the left. The same principle is used to make the second fixed section 402 pass through the channel 2 on the left, so that the installation of the steel cable 4 is completed. After the installation of the steel cable 4 is completed, the elastic driving member 5 will give the locking unit 3 a preliminary pre-tightening force to lock the steel cable 4. When the steel cable 4 is subjected to a downward pulling force as a whole, it will further drive the locking units 3 in the two channels 2 to further lock the ends of the steel cable 4, thereby ensuring the stability of the ends of the steel cable 4.

[0046] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
