Description

Technical Field

[0001] The invention belongs to the technical field of cable processing and testing, and in particular relates to a cable strength detection device. Background Art

[0002] Cables are carriers in the process of electric power transmission and are also indispensable carriers for the use of electric energy. Electric energy generated by power plants can be transmitted to various power consumption areas through cables. Therefore, the primary function of cables is long-distance power transmission. The length of the cable determines the transmission distance. Since the cable body is relatively long, it is particularly important to understand its transmission effect in various environments. Therefore, the tensile test of the cable is also an important part of cable processing.

[0003] Cable strength testing is a key step to ensure that the cable can withstand the expected mechanical stress, environmental factors and other potential impacts during installation and use; this involves a variety of tests to verify whether the physical and electrical properties of the cable meet the relevant standards and specifications. There are several tests: tensile test, bending test, impact test and other tests.

[0004] The tensile test is to fix the cable sample on the tensile testing machine and gradually apply tensile force until the sample breaks. The maximum tensile force value at the time of breakage is recorded, and then the tensile strength of the cable is judged to meet the design requirements based on the maximum tensile force value; the bending test is to repeatedly bend the cable for a certain number of times or keep it at a fixed curvature radius for a period of time, that is, repeated bending test and fixed bending test, and check whether the cable has cracks, breakage or other forms of damage.

[0005] When the cable breaks due to the unbearable tension during the tensile test, the tensile machines on both sides are still providing tension to the cable. The tension inside the cable is released at the moment the cable breaks, causing the cable to rebound quickly. During this process, the broken cable may whip the staff near the detection device, posing a safety hazard and needs to be improved.

[0006] At the same time, the existing test equipment only fixes the cable by clamping. In some cases, the cable is very easy to slip off, which may cause inaccurate detection and damage to the staff. Summary of the invention

[0007] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a cable strength detection device.

[0008] The technical solution adopted to solve the above technical problems is: a cable strength testing device, including a base, a control host is fixedly arranged on one side of the upper outside of the base, a display is arranged inside the control host, a stretching mechanism is arranged in the middle part of the upper outside of the base, the stretching mechanism performs a tensile test on the cable, a bending mechanism is arranged on the side of the upper outside of the base away from the control host, the bending mechanism performs a bending test on the cable, a fixed cable rack is arranged on the upper outside of the base, and cables are arranged between the fixed cable racks.

[0009] Through the above technical solution, the various baffles on the outside of the stretching mechanism can play a protective role while performing tensile tests, and the bending mechanism can perform two different modes of bending tests on the cable to increase the detection range of the cable. Finally, the setting of the cable rack is fixed, so that the cable fixation will be different from the conventional clamping fixation method, and the position of the cable can be better adjusted to facilitate multiple tests.

[0010] Furthermore, the stretching mechanism includes a tensile testing machine fixedly arranged in the middle of the upper part of the base, a mobile end is arranged outside the tensile testing machine, a fixed cable rack is fixedly connected to the lower surface of the outer part of the mobile end, a fixed hook is fixedly connected to the upper part of the outer part of the mobile end, a fixed guide wheel is fixedly connected to the front side of the upper part of the outer part of the tensile testing machine, a lifting rope is arranged outside the fixed guide wheel, one end of the lifting rope is wrapped around the outside of the fixed hook, and the lifting rope is fixedly connected to an end plate at the end away from the fixed hook.

[0011] Through the above technical solution, the mobile end will drive the fixed cable rack to move, and at the same time drive the lifting rope to move up and down, and the lifting rope is restricted by the fixed guide wheel and will not fall off easily.

[0012] Furthermore, the stretching mechanism also includes a locking baffle fixedly connected to the outside of the tensile testing machine, a locking rope plate is fixedly connected to the upper part of the locking baffle, a first telescopic baffle is arranged inside the locking baffle, a first rope plate is fixedly connected inside the first telescopic baffle, a second telescopic baffle is arranged inside the first telescopic baffle, a second rope plate is fixedly connected inside the second telescopic baffle, rope holes are opened inside the locking rope plate, the first rope plate and the second rope plate, and the lifting rope is located in the rope holes opened inside the locking rope plate, the first rope plate and the second rope plate.

[0013] Through the above technical solution, when the lifting rope moves upward near the moving end, the first telescopic baffle and the second telescopic baffle will rely on their own gravity and drive the other end of the lifting rope to descend through the end plate, thereby achieving a protective effect.

[0014] Furthermore, the engaging baffle, the first telescopic baffle and the second telescopic baffle are all made of transparent materials.

[0015] Through the above technical solution, the staff can directly observe the cables inside the cable at close range through the engaging baffle, the first telescopic baffle and the second telescopic baffle.

[0016] Furthermore, the bending mechanism includes a support plate fixedly connected to the base, the support plates are symmetrically arranged, and slide grooves are opened inside the support plates. An electric telescopic rod is arranged between the support plates, and the fixed end of the electric telescopic rod is fixedly connected to the base, and the movable end of the electric telescopic rod is fixedly connected to a lifting wheel, and sliding rods are fixedly connected to the two sides of the outside of the lifting wheel, and the sliding rods are located inside the slide groove, and a groove is opened inside the lifting wheel.

[0017] Through the above technical solution, the cable will be stuck in the groove when undergoing a bending test, and the lifting wheel can be moved up and down by an electric telescopic rod, which is convenient for cooperating with the mobile end to adjust different bending curvatures.

[0018] Furthermore, a first fixing rod and a second fixing rod are fixedly arranged inside the fixed cable rack, a wire groove is opened on one side inside the fixed cable rack, a winding wheel is connected to one side outside the fixed cable rack, a bending hole is opened inside the winding wheel, the bending hole is opened from the middle of the side surface of the winding wheel, and is bent inside the winding wheel and terminated from above the winding wheel.

[0019] Through the above technical solution, the first fixing rod has the effect of winding the cable, and the second fixing rod has the effect of adjusting the cable after the cable is wound around the first fixing rod. At the same time, the cable will pass through the bending hole and be wound around the outside of the winding wheel, so that the cable will not move easily or fall off easily.

[0020] Furthermore, a guide rod is fixedly connected to the outside of the fixed cable rack above the side where the winding wheel is located, a screw rod is provided on one side of the guide rod, the screw rod is fixedly connected to the fixed cable rack, a knob is sleeved on the outside of the screw rod, and a spring is connected to the outside of the guide rod.

[0021] Furthermore, a pressure plate is arranged outside the guide rod and the screw rod, the pressure plate is in an "Ω" shape, mounting holes are opened on both sides of the pressure plate, the guide rod and the screw rod are located inside the mounting holes, and a clamping barb is fixedly connected to the middle of the pressure plate.

[0022] Through the above technical solution, the pressure plate will compress and fix the end of the cable. At the same time, when the card is stuck, it can pierce into the inside of the cable, making the cable fixed more securely. Finally, the setting of the knob can adjust the degree of compression of the pressure plate, so that the cable can be quickly compressed and loosened.

[0023] The beneficial effects of the present invention are as follows: (1) The present invention can perform a tensile test on the cable through the setting of the stretching mechanism, and the multiple baffles carried on the outside can autonomously drop during the tensile test and enclose the cable to provide protection without causing harm to the staff. At the same time, the staff can closely observe the condition of the cable during the tensile test; (2) The setting of the bending mechanism includes a lifting wheel, and the lifting wheel can be lifted and moved autonomously and independently.

[0032] like Figure 5 - Figure 7As shown, a first fixing rod 505 and a second fixing rod 506 are fixedly arranged inside the fixed cable rack 500. The arrangement of the second fixing rod 506 can play a role in adjusting the cable. A wire groove 504 is provided on one side inside the fixed cable rack 500. A winding wheel 502 is connected to one side outside the fixed cable rack 500. A bending hole 503 is provided inside the winding wheel 502.

[0033] A guide rod 508 is fixedly connected to the outside of the fixed cable rack 500 above the side where the winding wheel 502 is located. A screw rod 501 is set on one side of the guide rod 508. The screw rod 501 is fixedly connected to the fixed cable rack 500. A knob 511 is placed on the outside of the screw rod 501. The outside of the guide rod 508 is connected to a spring 507.

[0035] The working principle of this embodiment is as follows. When using this device for detection, first connect one end of the cable to be detected to the inside of the fixed cable rack 500 outside the mobile end 104, that is: first wrap the cable around the outside of the first fixed rod 505, and reserve a part to pass through the wire groove 504 and enter the bending hole 503, then wrap it around the outside of the winding wheel 502, and finally pass it between the pressing plate 509 and the fixed cable rack 500, and then rotate the knob 511 to press the pressing plate 509 to move toward the fixed cable rack 500 until the thorn 510 penetrates into the inside of the cable, and the cable is pressed and fixed by the pressing plate 509, so that one end of the cable can be fixed, and then choose where to fix the other end of the cable according to the type of test that the cable needs to be tested.

[0037] When performing a bending test, the cable needs to be bent outside the second fixed rod 506 for adjustment. At the same time, the other end of the cable is fixed inside the fixed cable rack 500 on the outer side of the bending mechanism according to the above method, and the cable is located inside the groove opened inside the lifting wheel 403, so that the bending test can be performed. When performing a repeated bending test, the mobile end 104 of the tensile testing machine 100 can be controlled by the control host 200 to continuously move back and forth, so that the cable is continuously bent back and forth outside the lifting wheel 403 to complete the repeated bending test; when performing a fixed bending test, the mobile end 104 of the tensile testing machine 100 is controlled by the control host 200 to move to a fixed position, and the cable is bent around the lifting wheel 403 to a fixed curvature radius and maintained for a period of time, and the fixed bending test can be completed in this period.
