Description

Technical Field

[0001] This utility model belongs to the field of wire rope testing technology, and in particular relates to a single-strand wire rope tensile testing mechanism. Background Technology

[0002] A single-strand wire rope tensile testing mechanism is a specialized device used to test the tensile strength, breaking load, and other mechanical properties of single-strand wire ropes. It is commonly used in wire rope production, quality inspection, and scientific research. This mechanism typically applies axial tension to the wire rope through mechanical or hydraulic devices, while simultaneously monitoring the tension value and wire rope deformation until the wire rope breaks, in order to evaluate its mechanical properties.

[0003] Normally, when conducting tests, it is necessary to first fix both ends of the wire rope. The existing fixing method is mostly to use flat-nose pliers to fix the wire rope. This fixing method is relatively simple and not secure enough. When the tension is large, the wire rope is prone to slipping, causing the wire rope to come off the flat-nose pliers, which affects the accuracy of the test. Therefore, we propose a single-strand wire rope tension testing mechanism. Utility Model Content

[0004] The purpose of this invention is to provide a single-strand steel wire rope tensile testing mechanism. This invention utilizes a fixing part, specifically by winding one end of the steel wire rope around the outer surface of the winding column of the upper winding drum, and tightening the hexagonal nut clockwise with a wrench. This causes the three clamping blocks on the back of the movable circular block to press the steel wire rope, partially inserting it into the clamping groove, thus fixing one end. After winding the steel wire rope around the outer surface of the upper winding drum, the remaining portion is wound onto the lower winding drum. The other end is fixed in the same way. By fixing both ends and increasing friction through double-drum winding, the steel wire rope can be firmly fixed to the winding drum, ensuring accurate test results. This solves the problem that existing fixing methods often use flat-jaw pliers, which can easily cause the steel wire rope to detach from the pliers under high tension, thus affecting test accuracy.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a single-strand steel wire rope tensile testing mechanism, comprising a testing machine.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0038] Please see Figures 1-7 As shown, this utility model is a single-strand steel wire rope tensile testing mechanism, including a testing machine 1. The testing machine 1 includes a base 11, with support frames 12 fixedly connected to the top left and right sides of the base 11. A back plate 17 is fixedly connected to the top back of the base 11, and a top plate 16 is fixedly connected to the top of the two support frames 12. It also includes:

[0039] Fixing part 2, installed inside the testing machine 1, is used to fix the wire rope; and

[0040] Protective part 3 is installed on the front of the testing machine 1. Protective part 3 is used to prevent the wire rope from flying and injuring people.

[0041] A hydraulic cylinder 15 is fixedly connected to the top left side of the base 11, and a lifting plate 13 is fixedly connected to the top output end of the hydraulic cylinder 15. A limit post 14 is fixedly connected to the top right side of the base 11. The lifting plate 13 and the limit post 14 are in sliding limit cooperation. The lifting plate 13 and the two support frames 12 are in sliding limit cooperation. The two support frames 12 and the limit post 14 work together to keep the lifting plate 13 stable when it moves.

[0042] The fixing part 2 includes two winding rollers 21, both of which are installed inside the testing machine 1. The two winding rollers 21 are used to wind the wire rope around its outer surface.

[0043] The clamping assembly 22 is installed on the front of the winding drum 21 and is used to fix one end of the wire rope.

[0044] The winding roller 21 has a mounting plate 211 fixedly connected to its back. The upper winding roller 21 is fixedly connected to the bottom of the lifting plate 13 through the mounting plate 211, and the lower winding roller 21 is fixedly connected to the top of the base 11 through the mounting plate 211.

[0045] The protective section 3 includes a storage door 31, a telescopic door 32, and an observation door 33. The storage door 31, the telescopic door 32, and the observation door 33 are all installed on the front of the testing machine 1. The storage door 31, the telescopic door 32, and the observation door 33 are used to prevent the wire rope from splashing out of the testing machine 1.

[0046] The sliding door 32 and the storage door 31 are in sliding limit cooperation, and the observation door 33 is in sliding limit cooperation with the sliding door 32. The observation door 33 has an observation window on the front, and an acrylic plate is installed inside the observation window.

[0047] The front of the winding roller 21 is fixedly connected to the winding column 212. The winding column 212 has a locking groove 213 inside. The front of the winding column 212 has two limiting grooves 214. The front of the winding roller 21 has three pressing grooves 215.

[0048] Among them, the two limiting grooves 214 are symmetrically arranged, and the winding column 212 is used to wind the wire rope around its outer surface.

[0049] The clamping assembly 22 includes a bolt 222, with an internal hex nut 223 fixedly connected to the front of the bolt 222, an anti-loosening round block 224 fixedly connected to the back of the bolt 222, and a rotating round block 225 fixedly connected to the outer surface of the bolt 222.

[0050] Among them, the outer surface of the bolt 222 is rotatably connected to the movable circular block 221, and the movable circular block 221 has a rotating groove 226 inside. The bolt 222 is rotatably connected to the rotating groove 226 through the rotating circular block 225.

[0051] Three clamping blocks 227 are fixedly connected to the back of the movable circular block 221, and two limiting arc blocks 228 are fixedly connected to the back of the movable circular block 221. One end of the wire rope is wound around the outer surface of the winding column 212 of the upper winding roller 21, and the internal hex nut 223 is tightened clockwise with a wrench. This causes the three clamping blocks 227 on the back of the movable circular block 221 to squeeze the wire rope so that part of it enters the clamping groove 215, thus fixing one end. After the wire rope is wound around the outer surface of the upper winding roller 21, the remaining part is wound around the lower winding roller 21. The other end is fixed in the same way. By fixing both ends and winding with double rollers to increase friction, the wire rope can be firmly fixed on the winding roller 21, ensuring accurate test results.

[0052] Among them, the two limiting arc blocks 228 are symmetrically arranged, the limiting arc blocks 228 and the limiting groove 214 slide and limit each other, and the pressing block 227 is adapted to the pressing groove 215.

[0053] The telescopic gate 32 and the observation gate 33 each have two moving slots 35 on the front and back. The storage door 31 and the telescopic gate 32 each have four anti-detachment blocks 34 fixedly connected to their right sides. When you grasp the handle on the observation door 33 and push it to the left, when the left side of the handle contacts the right side of the telescopic gate 32 and the right side of the storage door 31 respectively, the observation door 33 will drive the telescopic gate 32 to move to the left until both are stored inside the storage door 31. After the steel wire rope is fixed, push the handle to the right. When the observation door 33 moves to its limit position, it will drive the telescopic gate 32 to move to the right until the right side of the observation door 33 contacts the right support frame 12 to complete the closure. The staff can observe the status of the steel wire rope through the acrylic observation window on the observation door 33. The storage door 31, the telescopic gate 32 and the observation door 33 can prevent the steel wire rope from breaking and flying and injuring people.

[0054] Among them, the anti-detachment block 34 and the moving groove 35 are slidably limited together, and the anti-detachment block 34 and the moving groove 35 work together to prevent the telescopic gate 32 and the observation gate 33 from falling off.

[0055] A specific application of this embodiment is as follows: In use, grasp the handle on the observation door 33 and push it to the left. When the left side of the handle contacts the right side of the telescopic door 32, it will cause the telescopic door 32 to move to the left as well. When the left side of the handle contacts the right side of the storage door 31, the observation door 33 and the telescopic door 32 have been stored inside the storage door 31. At this time, one end of the steel wire rope can be wound around the outer surface of the winding column 212 located on the upper winding roller 21. Then, use a wrench to tighten the hexagonal nut 223 clockwise, causing the bolt 222 to move backward. During the backward movement of the bolt 222, the rotating block 225 on its outer surface is rotatably connected to the rotating groove 226 in the moving block 221, and the back of the moving block 221... Two limiting arc blocks 228 slide and limit the groove 214, so the moving block 221 will move horizontally backward, causing the three pressing blocks 227 on its back to squeeze the wire rope, so that part of it enters the pressing groove 215. This method, through the cooperation of the pressing blocks 227 and the pressing groove 215, can firmly fix the wire rope. Then the wire rope is wound around the outer surface of the upper winding roller 21, and the remaining part of the wire rope is wound around the lower winding roller 21. The other end of the wire rope is fixed in the same way. This method fixes both ends of the wire rope respectively, and then it is wound around the outer surface of the two winding rollers 21 to further increase the friction and ensure the accuracy of the test results.

[0056] Then, grasp the handle on the observation door 33 and push it to the right. When the observation door 33 moves to its rightmost position, it will move to the right along with the telescopic door 32 via the two anti-detachment blocks 34 on the telescopic door 32, until the right side of the observation door 33 contacts the support frame 12 located on the right side, thus completing the closing. Then, the hydraulic cylinder 15 is activated to extend, driving the lifting plate 13 to move upward. During the upward movement of the lifting plate 13, it slides and limits the movement with the limit post 14, making the movement of the lifting plate 13 more stable. The pressure sensor (DGZ-11 / K280bar) is installed inside the hydraulic cylinder 15. The force generated when the wire rope is stretched is transmitted to the hydraulic cylinder 15 through the lifting plate 13. The pressure sensor can detect the hydraulic pressure change and then calculate the tension value of the wire rope. During the test, the staff can observe the condition of the wire rope through the observation window on the observation door 33. The observation window is made of acrylic material. The storage door 31, the telescopic door 32 and the observation door 33 can effectively prevent the wire rope from breaking and flying during the test, which could cause injury to the staff. After the test, use a wrench to turn the two hex nuts 223 counterclockwise to release the wire rope and then remove it.
