Description

Technical Field

[0001] The utility model relates to the technical field of wire rope breaking test fixtures, in particular to a wire rope fastener anti-falling force and anti-dislocation tension fixture. Background Art

[0002] Steel wire rope is a spiral steel wire bundle twisted together according to certain rules with steel wires that meet the requirements of mechanical properties and geometric dimensions. It is first twisted into strands by multiple layers of steel wires, and then a certain number of strands are twisted into a spiral rope with the rope core as the center. It has the advantages of being light to use and having high tensile strength. During the production process of steel wire rope, it is necessary to conduct a wire rope breaking test to test its maximum load-bearing capacity, that is, the breaking tension, so as to evaluate the quality and reliability of the steel wire rope.

[0003] The applicant retrieved and obtained the following prior art, specifically, the patent with publication number CN220104661U discloses a wire rope breaking test fixture, which relates to the technical field of wire rope breaking test fixtures. A wire rope breaking test fixture, including an outer frame installed on a tensile machine, the outer frame is provided with a mounting groove, and also includes: an inner ring conical connection seat installed in the mounting groove of the outer frame, a first three-claw conical clamping block for clamping the wire rope is slidably connected in the inner ring conical connection seat; a connecting rod, the connecting rod is arranged on the outer frame, and is used to connect one end of the wire rope; the utility model changes the original method of clamping and fixing the wire rope by the clamp to connecting by the connecting rod by adding a connecting rod, thereby reducing the clamping force of the first three-claw conical clamping block and the second three-claw conical clamping block on the wire rope, thereby effectively avoiding the wire rope from breaking from the clamping end face during the pulling test.

[0004] It can be seen from the above patent that although this wire rope breaking test fixture effectively avoids the wire rope from breaking from the clamping end face during the pulling test by adding a connecting rod, in actual use, since the connecting rod is horizontally arranged inside the push screw sleeve, the tester needs to wrap the wire rope around and tie it to the connecting rod, which not only makes the installation operation of the wire rope difficult, but also reduces the test efficiency, and is not convenient to remove and replace the wire rope for secondary experiments. It is also not convenient to disassemble and replace the first three-claw conical clamp and the second three-claw conical clamp to test wire ropes of different diameters. Utility Model Content

[0005] The main purpose of the utility model is to provide a wire rope fastener anti-fall-off force and anti-dislocation tension clamp, aiming to solve the problems that the existing wire rope breaking test clamp is difficult to install and operate the wire rope, reduces the test efficiency, is inconvenient to dismantle the wire rope for secondary testing, and is inconvenient to test wire ropes of different diameters.

[0007] Preferably, the conical limiting hole has the same taper as the conical chuck and the length of the conical chuck is greater than the length of the chuck, so that one end of the conical chuck used to extend into the chuck passes through the conical limiting hole and extends out of the chuck.

[0008] Preferably, a notch groove is provided on the outer wall of the tapered chuck, and the notch groove extends from an end surface of one end of the tapered chuck to the annular groove.

[0009] Preferably, a jacket is provided in the through hole, and a limiting groove for the jacket to extend into is formed on an end surface of the conical jacket barrel close to the notch groove.

[0029] Embodiment 1:

[0030] The utility model provides a steel wire rope fastener anti-falling force and anti-dislocation tension clamp.

[0031] In one embodiment of the utility model, a wire rope fastener anti-dropping force and anti-dislocation tension clamp includes a chuck 1 and a conical chuck 2, the conical chuck 2 is provided with a through hole 3 for the wire rope to pass through, the chuck 1 is provided with a conical limiting hole 4 for the conical chuck 2 to extend into along its extension direction, one end of the conical chuck 2 is provided with an annular groove 5 for accommodating the wire rope, and an end cover 10 for abutting against the conical chuck 2 is detachably installed at one end of the chuck 1 close to the annular groove 5, and a plurality of protrusions 11 are formed at intervals on one side of the end cover 10 facing the conical chuck 2, and an adjustment hole 12 is provided on the other side of the end cover 10.

[0032] Specifically, Figures 1 to 4 As shown, in the utility model, a wire rope fastener anti-falling force and anti-dislocation tension clamp is provided with a through hole 3 in the conical clamp 2, so that the wire rope can pass through the conical clamp 2, and an annular groove 5 for accommodating the wire rope is provided at one end of the conical clamp 2, and an end cover 10 is detachably installed at the end of the clamp 1 close to the annular groove 5, and the end cover 10 and the clamp 1 can be detachably installed in a threaded connection, so that the end cover 10 is easy to disassemble and assemble, and the end cover 10 can prevent the conical clamp 2 from falling off from the clamp 1 when not in use, thereby ensuring the integrity of the device as a whole and facilitating storage and placement; at the same time, since the end cover 10 faces A plurality of protrusions 11 are formed at intervals on one side of the conical collet 2. When a breaking tension test is required for the steel wire rope, the tester passes the steel wire rope through the through hole 3 and winds it around the plurality of protrusions 11 in an "8" shape, and then winds it in the annular groove 5. At this time, the conical collet 2 and the end cover 10 are installed in the conical limiting hole 4 of the chuck 1 and the adjusting hole 12 is screwed with the help of an external tool, so that the end cover 10 gradually moves into the conical limiting hole 4 and simultaneously pushes the conical collet 2, so that the outer wall of the conical collet 2 abuts against the hole wall of the conical limiting hole 4, thereby clamping and limiting the steel wire rope in the annular groove 5. The installation operation is simple and convenient, the use is flexible, and the test efficiency is improved.

[0033] It can be understood that the utility model is a wire rope fastener anti-falling force and anti-dislocation tension clamp. By installing the conical clamp 2 in the conical limiting hole 4, and the large end diameter of the conical clamp 2 is larger than the small end diameter of the conical limiting hole 4, the conical clamp 2 can be effectively prevented from falling off from the chuck 1 during the wire rope breaking tension test. The overall structural design is simple and reasonable, saving manufacturing costs. In addition, after a single experiment is completed, the tester can remove the conical clamp 2 by disassembling the end cover 10, and can quickly and conveniently remove the broken wire rope for a secondary experiment. At the same time, different conical clamps 2 can be replaced, and the taper of different conical clamps 2 should be consistent with the taper of the conical limiting hole 4, but they are respectively provided with through holes 3 of different diameters, so that the breaking tension test can be performed on wire ropes of different diameters, and the conical clamp 2 is easy to disassemble and replace, and reliable to use.

[0034] In one embodiment, specifically, Figure 2 As shown, the conical limiting hole 4 is consistent with the taper of the conical chuck 2 and the length of the conical chuck 2 is greater than the length of the chuck 1, so that one end of the conical chuck 2 that is used to extend into the chuck 1 passes through the conical limiting hole 4 and extends out of the chuck 1, thereby preventing the small end of the conical chuck 2 from contracting in the radial direction of the wire rope and clamping off the wire rope under the continuous push of the end cover 10.

[0035] In one embodiment, a notch groove 6 is formed on the outer wall of the conical chuck 2, and the notch groove 6 extends from one end surface of the conical chuck 2 to the annular groove 5. Figures 1 to 4 As shown, specifically, after the steel wire rope is wound around a number of protrusions 11, the steel wire rope is wound into the annular groove 5 through the notch groove 6, and the notch groove 6 can provide a storage space for the steel wire rope, thereby preventing the steel wire rope from being wound around the outer wall of the conical chuck 2 and causing unstable abutment between the conical chuck 2 and the conical limiting hole 4, thereby improving the installation stability of the conical chuck 2.

[0036] In one embodiment, a jacket 7 is disposed in the through hole 3, and a limiting groove 8 for the jacket 7 to extend into is provided on the end surface of the conical jacket 2 near the notch groove 6. Figures 1 to 3 As shown, the jacket 7 replaces the conical chuck 2 to contact the wire rope, so that not only can a more uniform clamping force be applied to the wire rope to improve the stability of the wire rope, but also the conical chuck 2 can be prevented from being worn by the wire rope after long-term use, which causes the through hole 3 to become larger or deformed, thereby extending the service life of the conical chuck 2. In addition, the jacket 7 can be made of high-hardness material, and the jacket 7 can be axially limited by the limiting groove 8. The installation method of the jacket 7 can be adopted as an interference fit with the through hole 3, and the structural design is simple and reasonable.

[0037] In one embodiment, a guide hole 9 is formed at one end of the tapered chuck 2 for extending out of the chuck 1, and the guide hole 9 is gradually narrowed along the extension direction of the tapered chuck 2. Specifically, Figure 1 and Figure 2 As shown, the guide hole 9 facilitates the steel wire rope to pass through the through hole 3, which is beneficial for winding and installing the steel wire rope and is easy to use.

[0038] In one embodiment, if Figure 2 As shown, the end face edges at both ends of the conical chuck 2 are chamfered, which not only prevents the edges of the end faces of the conical chuck 2 from scratching the hole wall of the conical limiting hole 4, thereby extending the service life of the chuck 1, but also improves the smoothness of the conical chuck 2 being inserted into the conical limiting hole 4.

[0039] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
