Description

Technical Field

[0001] The utility model relates to the technical field of cable testing, in particular to a cable tensile performance testing device. Background Art

[0002] Cable is a general term for items such as optical cables and electrical cables. They have many uses, mainly for controlling installations, connecting devices, and transmitting electricity. They are common and indispensable in daily life.

[0003] Existing cables need to undergo tensile testing after production, but the distance between the tension arms of current cable tensile performance testing equipment is fixed, which has poor flexibility and cannot be adjusted, thus affecting work efficiency. When testing the cable tension, it may break and cause damage to the equipment. However, there is currently a lack of protection for cable tensile performance testing equipment, which poses certain safety risks.

[0004] Therefore, in view of the problems that the above-mentioned existing cable testing equipment has poor flexibility, is inconvenient for testing small cables, and lacks a protective structure for the testing equipment, a cable tensile performance testing equipment can be designed to facilitate the adjustment of the tension arm to make it adaptable to cables of different lengths, and add a protective cover to prevent the cable from breaking and causing damage to the testing equipment. Utility Model Content

[0007] Preferably, the test equipment can fix cables of different sizes by moving the pulling arm, and the lifting plate is driven up and down by the telescopic cylinder, so that the hook pulls the cable to complete the tensile test, and the test device is protected by a protective cover set on the right side of the upper end of the base.

[0008] Preferably, a driving motor is fixedly installed on the inner side of the base, and a double-headed threaded rod is fixedly installed on the output end of the driving motor. The threads at both ends of the double-headed threaded rod are opposite and have equal pitches. The other end of the double-headed threaded rod is rotatably connected to the base. The front and rear ends of the surface of the double-headed threaded rod are threadedly connected with threaded blocks. The double-headed threaded rod is rotated by the driving motor, so that the threaded blocks threadedly connected to the double-headed threaded rod move inward or outward at the same time, which is convenient for adjusting the test device.

[0009] Preferably, a sliding groove is provided at the upper end of the base, and a slider is slidably connected in the sliding groove. One end of the slider is fixedly connected to the threaded block, and the other end of the slider is fixedly connected to the tension arm. The slider enables the tension arm to slide synchronously with the threaded block along the direction of the sliding groove, thereby facilitating the adjustment of the distance between the two tension arms.

[0010] Preferably, the end of the tension arm close to the fixed column is detachably connected to the mounting bracket by bolts, and the end of the mounting bracket surface away from the tension arm is fixedly mounted with a tension ring, which is convenient for replacement when the tension ring is damaged.

[0013] Preferably, a shock-absorbing pad is provided on the inner side of the surface of the protective cover. The shock-absorbing pad is made of rubber. Airbag columns are provided on the inner side of the shock-absorbing pad. The airbag columns are distributed at equal intervals.

[0014] Beneficial effects of the utility model:

[0015] 1. This cable tensile performance test equipment uses a drive motor, a slider, and a double-threaded rod. The drive motor first drives the double-threaded rod to rotate, causing the threaded block to move inward or outward at the same time, and drives the slider to slide synchronously along the slide groove, thereby driving the tension arm to slide along the slide groove direction. This makes it easy for staff to adjust the distance between the two tension arms at any time, making it adaptable to cables of different lengths, thereby improving the flexibility of the test equipment.

[0016] 2. The cable tensile performance testing equipment uses a protective cover, shock-absorbing pad and airbag column. When the cable breaks, the cable will hit the shock-absorbing pad, and the airbag column will further reduce the impact force of the hit, so that the impact force caused by the cable breakage is fully buffered, thereby reducing the occurrence of safety hazards. The protective cover will cover the cable, so that the cable will not fly around when it breaks, which is convenient for staff to clean and improves convenience. BRIEF DESCRIPTION OF THE DRAWINGS

The upper end of the base 1 is located on both sides of the fixing column 3 and a protective cover 7 is provided on the right side of the upper end of the base 1. A handle 75 is fixedly installed on the surface of the protective cover 7. By moving the pulling arm 2, the test equipment can fix cables of different sizes, and the telescopic cylinder 4 drives the lifting plate 5 to move up and down, so that the hook 6 pulls the cable to complete the tensile test, and the test device is protected by the protective cover 7 provided on the right side of the upper end of the base 1.

[0025] See also Figure 1 、 Figure 2 、 Figure 3 , in this embodiment, a driving motor 11 is fixedly installed on the inner side of the base 1, and a double-headed threaded rod 12 is fixedly installed on the output end of the driving motor 11. The threads at both ends of the double-headed threaded rod 12 are opposite and have equal pitches. The other end of the double-headed threaded rod 12 is rotatably connected to the base 1, and the front and rear ends of the surface of the double-headed threaded rod 12 are threadedly connected with threaded blocks 13. The double-headed threaded rod 12 is rotated by the driving motor 11 so that the threaded blocks 13 threadedly connected to the double-headed threaded rod 12 move inward or outward at the same time, which is convenient for adjusting the test device. A slide groove 14 is provided at the upper end of the base 1, and a slider 15 is slidably connected to the slide groove 14. One end of the slider 15 is fixedly connected to the threaded block 13, and the other end of the slider 15 is fixedly connected to the pulling arm 2. The slider 15 enables the pulling arm 2 to slide synchronously with the threaded block 13 along the direction of the slide groove 14, which is convenient for adjusting the distance between the two pulling arms 2.

[0026] See also Figure 1 、 Figure 4 、 Figure 5In this embodiment, the end of the tension arm 2 near the fixed column 3 is detachably connected to a mounting bracket 21 via bolts. A tension ring 22 is fixedly mounted on the end of the mounting bracket 21 away from the tension arm 2, facilitating replacement of the tension ring 22 when damaged. Preferably, four support columns 8 are fixedly mounted on the lower end of the base 1. Anti-slip pads 9 are fixedly mounted on the lower ends of the support columns 8 to support the base 1 and provide greater stability for the overall structure. The lower end of the protective cover 7 is rotatably connected to the upper end of the base 1 via a hinge. The upper end of the protective cover 7 is fixedly connected to a bonding plate 71.

[0027] When working, first open the protective cover 7 through the handle 75, and at the same time test the size of the cable as needed, start the driving motor 11 to rotate the double-headed threaded rod 12, so that the slider 15 fixed on the threaded block 13 drives the slide 15 to slide along the direction of the slide groove 14, thereby adjusting the distance between the two tension arms 2, so as to adapt to cables of different sizes. After the tension arm 2 is adjusted to the appropriate position, both ends of the cable to be tested are fixed on the tension ring 22, and then the protective cover 7 is rotated with the hinge as the axis, and the fitting plate 71 and the base 1 are fitted together. Then start the telescopic cylinder 4, and the telescopic cylinder 4 lifts the lifting plate 5, so that the hook 6 pulls the cable for tensile testing.
