Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy cable processing technology, specifically to an aluminum alloy cable tensile testing device. Background Technology

[0002] The aluminum alloy cable tensile testing device is a specialized instrument used to test the tensile strength of cables. Driven by hydraulic pressure or a servo motor, it applies axial tension to the cable sample, monitors and records the tensile force, displacement changes, and fracture critical point in real time, and generates stress-strain curves to evaluate the material's strength, ductility, and reliability. This tensile testing device is suitable for product quality inspection in fields such as power and rail transportation. Its compact structure and intelligent operating interface improve testing efficiency and ensure the safety of cables in engineering applications.

[0003] The cable tensile testing device disclosed in Chinese Patent Publication No. CN221174121U utilizes the cooperation of components such as a first servo motor, a first worm gear, a second worm gear, a transmission belt, a first worm wheel, a straight rod, a drive rod, a connecting rod, and a second L-shaped plate. Under the rotation of the two first worm wheels, the drive rod fixed to adjacent first worm wheels causes adjacent fixed frames to move to opposite sides, limited by two adjacent telescopic rods. The connecting rod fixed to adjacent fixed frames causes adjacent second L-shaped plates to move to opposite sides, facilitating the fixing of cables of different sizes and expanding the device's applicability. However, the overall safety of the tensile testing device is relatively low. As the tensile force applied to the aluminum alloy cable gradually increases, the aluminum alloy cable may break. The stress generated by the breakage could cause injury to the testing personnel, thus affecting the safety and stability of the testing device. Utility Model Content

[0004] The purpose of this invention is to provide an aluminum alloy cable tensile testing device to solve the problems mentioned in the background art.

[0006] Preferably, the first limiting mechanism includes positioning holes evenly spaced around the inside of the upper surface of the fixed cylinder, a bolt is threaded inside the upper surface of the fixed cylinder, a pressure plate is rotatably connected to the bottom end of the bolt, limiting blocks that slide inside the fixed cylinder are fixedly connected to both sides of the pressure plate, a throttle is sleeved on the outside of the upper surface of the bolt, and positioning rods are fixedly connected to the left and right sides of the lower surface of the throttle.

[0007] Preferably, the second limiting mechanism has the same specifications as the first limiting mechanism, both of which are provided with positioning holes, bolts, pressure plates, limiting blocks, throttles, and positioning rods. The second limiting mechanism can limit the aluminum alloy cable inside the movable cylinder.

[0008] Preferably, the moving mechanism includes a servo motor fixedly connected to the center position on the right side inside the testing platform. A threaded rod is installed on the output shaft end of the servo motor, and a threaded block is connected to the external thread of the threaded rod. The upper surface of the threaded block is fixedly connected to the tensile testing instrument.

[0009] Preferably, the end of the pull rope away from the movable cylinder is fixedly connected to the movable cover, and the movement of the movable cylinder can drive the movement of the movable cover by the pull rope.

[0010] Preferably, the fixed cylinder, movable cylinder, fixed cover, and movable cover are all made of reinforced glass, and the tensile testing instrument is an Instron 3365 testing instrument.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This aluminum alloy cable tensile testing device has a fixed cover fixed to the center of the test platform surface. The fixed cover can cover the center of the aluminum alloy cable tensile test inside. At the same time, the two sides of the movable cylinder are connected to the movable cover inside the fixed cover by pull ropes. When the movable cylinder pulls the cable to move, the pull ropes on both sides of the movable cylinder can pull the movable cover to move synchronously, thereby effectively protecting the aluminum alloy cable tensile test and improving the overall safety of the tensile testing device.

[0013] 2. This aluminum alloy cable tensile testing device features limiting mechanisms in both the fixed and movable cylinders. By rotating the bolts on both cylinders, the bolts can push the pressure plate to compress and limit the aluminum alloy cable within the cylinders. Furthermore, by placing the throttle handle over the bolt's upper surface, the positioning rod on the throttle handle can be inserted into the positioning hole on the fixed cylinder, thus stabilizing and limiting the bolt and pressure plate. This prevents cable loosening during subsequent testing, which could affect the test results, and improves the overall stability of the aluminum alloy cable tensile testing device.

[0024] The end of the pull rope 701 away from the movable cylinder 7 is fixedly connected to the movable cover 901. The movement of the movable cylinder 7 can drive the movable cover 901 to move through the pull rope 701.

[0025] Fixed cylinder 2, movable cylinder 7, fixed cover 9, and movable cover 901 are all made of reinforced glass, and tensile testing instrument 6 uses Instron 3365 testing instrument.

[0026] Example 2 differs from Example 1 mainly in that:

[0027] A tensile testing device for aluminum alloy cables includes a testing platform 1. A fixed cylinder 2 is fixedly connected to the middle position of the left side of the upper surface of the testing platform 1. A first limiting mechanism 3 is provided inside the top of the fixed cylinder 2. A moving mechanism 5 is provided at the center position of the right side inside the testing platform 1.

A movable cover 901 is slidably connected inside the right side of the fixed cover 9.

[0028] The first limiting mechanism 3 includes positioning holes 201 evenly spaced around the inside of the upper surface of the fixed cylinder 2. A bolt 301 is threaded inside the upper surface of the fixed cylinder 2. A pressure plate 302 is rotatably connected to the bottom end of the bolt 301. Limiting blocks 303 that slide inside the fixed cylinder 2 are fixedly connected to both sides of the pressure plate 302. A handle 4 is sleeved on the outside of the upper surface of the bolt 301. Positioning rods 401 are fixedly connected to the left and right sides of the lower surface of the handle 4. Rotating the bolt 301 can push the lower pressure plate 302 to move up and down. At this time, the pressure plate 302 can perform the pressing work of the aluminum alloy cable inside the fixed cylinder 2 and sleeve the handle 4 on the outside of the upper surface of the bolt 301. At this time, the positioning rod 401 at the bottom end of the handle 4 can be inserted into the positioning hole 201 on the fixed cylinder 2 to complete the stable limiting work of the bolt 301 and the pressure plate 302.

[0029] The second limiting mechanism 8 has the same specifications as the first limiting mechanism 3, both of which are equipped with positioning holes 201, bolts 301, pressure plates 302, limiting blocks 303, throttles 4, and positioning rods 401. The aluminum alloy cable inside the movable cylinder 7 can be limited through the second limiting mechanism 8.

[0030] The moving mechanism 5 includes a servo motor 501 fixedly connected to the center position on the right side inside the testing table 1. A threaded rod 502 is installed on the output shaft end of the servo motor 501. A threaded block 503 is connected to the external thread of the threaded rod 502. The upper surface of the threaded block 503 is fixedly connected to the tensile testing instrument 6.

[0033] In this embodiment, the aluminum alloy cable to be tested is passed through the inside of the fixed cylinder 2 and inserted into the inside of the movable cylinder 7. By rotating the bolts 301 on both the fixed cylinder 2 and the movable cylinder 7, the bolts 301 can be pressed against both ends of the aluminum alloy cable by the pressure plate 302. The throttle 4 is then placed on the outside of the upper surface of the bolts 301, and the positioning rod 401 at the bottom of the throttle 4 can be inserted into the positioning hole 201 on the fixed cylinder 2, thus stabilizing and limiting the bolts 301 and the pressure plate 302. The servo motor 501 is then started, driving the threaded rod 502 to rotate. The threaded block 503 on the threaded rod 502 can then be moved by the tensile testing instrument 6, causing the movable cylinder 7 to move.
