Description

Wire Rope Core Load Capacity Testing Device Technical Field

[0001] This utility model relates to the technical field of steel wire rope core load-bearing capacity testing device, specifically a steel wire rope core load-bearing capacity testing device. Background Technology

[0002] A wire rope core load-bearing capacity testing device is used to evaluate the strength, durability, and load-bearing capacity of wire ropes under working conditions. It simulates the working conditions that wire ropes may endure in real-world applications, determining the safety factor and suitability of the wire rope. Wire ropes are widely used in various industrial sectors, such as cranes, mines, steel mills, ports, and construction. Therefore, testing their load-bearing capacity is crucial to ensure their safety and reliability. Precise measurement and analysis can help companies ensure that the wire ropes they use meet industry standards, avoiding accidents or equipment damage due to insufficient load-bearing capacity.

[0003] The shortcomings of existing technology:

[0004] When installing and using current wire rope core load-bearing capacity testing devices, traditional clamps often cause wire rope slippage or uneven clamping force due to fixed specifications. Furthermore, repeated adjustments to the positioning are required during clamping, resulting in unstable connections and cumbersome wire rope installation and clamping procedures. Summary of the Invention

[0005] The purpose of this invention is to provide a testing device for the load-bearing capacity of a wire rope core, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire rope core load-bearing capacity testing device, comprising a support frame, a crossbeam slidably connected to the inner side of the support frame, a clamping mechanism fixedly connected to both the crossbeam and the top of the support frame, and a protective mechanism slidably connected to the surface of the support frame, the clamping mechanism comprising:

[0007] A connecting rod is fixedly connected to the bottom of the crossbeam;

[0008] A positioning piece, which is sleeved on the surface of the connecting rod body;

[0009] A sliding ring, which is slidably connected to the surface of the connecting rod body;

[0010] The fixing plate is fixedly connected to the top of the connecting rod body;

[0011] Two sets of hydraulic push rods are sleeved on both sides of the positioning plate.

[0012] Preferably, the protective mechanism includes:

[0013] Limiting strips are slidably connected to both sides of the front of the support frame;

[0014] A protective cover, which is fixedly connected to one side of the limiting strip;

[0015] The four sets of damping hydraulic rods are fixedly connected to one side of the protective cover in a rectangular array.

[0016] A buffer spring is sleeved on the surface of a damping hydraulic rod.

[0017] Preferably, a protective plate is fixedly connected to one end of the damping hydraulic rod, and a cushioning pad is fixedly connected to the surface of the protective plate. The cushioning pad is made of rubber.

[0018] Preferably, two sets of connecting plates are fixedly connected to one side of the protective cover, and one side of the connecting plates is fixedly connected to the surface of the crossbeam.

[0019] Preferably, the clamping mechanism further includes:

[0020] The four sets of supporting spring components are fixedly connected to the top surface of the sliding ring in a circular array.

[0021] A pressure ring is fixedly connected to the top of the supporting spring.

[0022] Preferably, both ends of the crossbeam are threadedly connected to lifting screws, and a drive motor is fixedly connected to the top of the lifting screws.

[0023] Preferably, one end of one of the connecting rods is provided with a tension sensor, and the bottom of the support frame is fixedly connected with four sets of support seats in a rectangular array.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] 1. The wire rope core load-bearing capacity testing device includes a clamping mechanism comprising a connecting rod, a positioning plate, a sliding ring, a fixing plate, a hydraulic push rod, a support spring, and a pressure ring. In use, both ends of the wire rope are passed through the notches on the positioning plates and wrapped around the connecting rod once, then lowered through the notches. Activating the hydraulic push rod causes it to push the sliding ring, which slides on the surface of the connecting rod, pushing the pressure ring and the fixing plate to press against the surface of the wire rope, thus achieving convenient clamping of the wire rope. Simultaneously, the support spring, during the pushing of the pressure ring, reduces the direct impact on the wire rope surface through its elasticity, reduces the number of clamping steps, and increases clamping stability.

[0026] 2. The wire rope core load-bearing capacity testing device includes a protective mechanism comprising a limit bar, a protective cover, a damping hydraulic rod, and a buffer spring. During use, when excessive tension causes the test wire rope to break, the wire rope instantly strikes the surface of the buffer pad, and the instantaneous impact force pushes the protective plate, causing the damping hydraulic rod to contract under force and the buffer spring to deform under force and generate elastic force, thereby achieving a buffering and shock-absorbing effect. This prevents the wire rope from breaking during the test and causing injury to personnel or equipment, thus improving the safety of the wire rope core load-bearing capacity testing device.

[0037] Example 1

[0038] Please refer to Figures 1-5. The technical solution of the wire rope core bearing capacity testing device provided by this utility model includes a support frame 1, a crossbeam 2 slidably connected to the inner side of the support frame 1, a clamping mechanism 3 fixedly connected to the top of both the crossbeam 2 and the support frame 1, and a protective mechanism 4 slidably connected to the surface of the support frame 1. The clamping mechanism 3 includes a connecting rod 301, a positioning plate 302, a sliding ring 303, a fixing plate 304, and a hydraulic push rod 305. The connecting rod 301 is fixedly connected to the bottom of the crossbeam 2, the positioning plate 302 is sleeved on the surface of the connecting rod 301, and the sliding ring 303 is slidably connected to the surface of the connecting rod 301. The fixed plate 304 is fixedly connected to the top of the connecting rod 301. Two sets of hydraulic push rods 305 are sleeved on both sides of the positioning plate 302. In use, the two ends of the wire rope are passed through the notches on the positioning plate 302 and wrapped around the connecting rod 301. Then, the wire rope hangs down from the notches. The hydraulic push rods 305 are activated, which push the sliding ring 303. The sliding ring 303 slides on the surface of the connecting rod 301 and pushes the pressure ring 307 and the fixed plate 304 to cooperate and squeeze the wire rope surface, thereby achieving the effect of convenient clamping of the wire rope, reducing the work steps of wire rope installation and clamping, and increasing clamping stability.

[0039] The protective mechanism 4 includes a limit bar 401, a protective cover 402, a damping hydraulic rod 403, and a buffer spring 404. The limit bar 401 is slidably connected to both sides of the front of the support frame 1. The protective cover 402 is fixedly connected to one side of the limit bar 401. Four sets of damping hydraulic rods 403 are fixedly connected to one side of the protective cover 402 in a rectangular array. The buffer spring 404 is sleeved on the surface of the damping hydraulic rod 403. During use, when the tension is too great and the test wire rope breaks, the wire rope instantly strikes the surface of the buffer pad 6. The instantaneous impact force pushes the protective plate 5, causing the damping hydraulic rod 403 to contract under force and the buffer spring 404 to deform under force and generate elastic force, thereby achieving the effect of buffering and shock absorption. This prevents the wire rope from breaking during the test and causing damage to personnel or equipment, thus improving the safety of the wire rope core load-bearing performance testing device.

[0040] A protective plate 5 is fixedly connected to one end of the damping hydraulic rod 403, and a buffer pad 6 is fixedly connected to the surface of the protective plate 5. The buffer pad 6 is made of rubber.

[0041] Two sets of connecting plates 7 are fixedly connected to one side of the protective cover 402, and one side of the connecting plate 7 is fixedly connected to the surface of the crossbeam 2.

[0042] The clamping mechanism 3 also includes a support spring 306 and a pressure ring 307. Four sets of support springs 306 are fixedly connected to the top surface of the sliding ring 303 in a ring array. The pressure ring 307 is fixedly connected to the top of the support spring 306. During the process of pushing the pressure ring 307, the support spring 306 reduces the direct impact on the surface of the wire rope through its own elasticity.

[0043] Both ends of the crossbeam 2 are threadedly connected to lifting screws 8, and the top of the lifting screws 8 is fixedly connected to a drive motor 9.

[0044] One end of one of the connecting rods 301 is equipped with a tension sensor 10, and the bottom of the support frame 1 is fixedly connected with four sets of support seats 11 in a rectangular array.

[0045] In use, the two ends of the wire rope are passed through the notches on the positioning plate 302 and wrapped around the connecting rod 301. The rope then hangs down from the notches. Activating the hydraulic push rod 305 causes it to push the sliding ring 303. The sliding ring 303 slides on the surface of the connecting rod 301, pushing the pressure ring 307 and the fixing plate 304 to press against the surface of the wire rope, thus achieving convenient clamping of the wire rope. Simultaneously, the supporting spring 306, during the pushing of the pressure ring 307, utilizes its own elasticity... This reduces the direct impact on the surface of the wire rope, decreases the number of steps involved in installing and clamping the wire rope, and increases clamping stability. When excessive tension causes the test wire rope to break, the wire rope instantly strikes the surface of the buffer pad 6, and the instantaneous impact force pushes the protective plate 5, causing the damping hydraulic rod 403 to contract under force and the buffer spring 404 to deform under force and generate elastic force, thereby achieving the effect of buffering and shock absorption. This prevents the wire rope from breaking during the test and causing damage to personnel or equipment, thus improving the safety of the wire rope core load-bearing capacity testing device.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
