Description

Technical Field

[0001] This utility model relates to the field of cable production technology, specifically to a cable tensile strength testing device. Background Technology

[0002] As an important carrier for power transmission and signal transmission, the mechanical properties of cables, especially tensile strength, are directly related to the reliability of power supply systems and the stability of communication networks.

[0003] According to CN222013752U, a cable tensile strength testing device is disclosed. This technology discloses a technical solution including "a testing platform, a testing component fixedly connected to the top surface of the testing platform, two sets of clamping components fixedly connected to the inner side of the testing component, four sets of moving wheels rotatably connected to the bottom surface of the testing platform, and a controller fixedly installed on the top surface of the testing platform with the controller located on the front of the testing platform". It has the technical effect of "clamping and fixing a cable of a predetermined length through two sets of clamping components, which can fix and clamp cables of different diameters while maintaining connection stability, and then performing tensile strength testing on the cable fixed by the testing component. During the testing process, the cable is pulled upward to ensure that the cable is subjected to uniform force when stretched, and the tensile strength data of the cable is quickly obtained after the cable breaks and displayed on the display panel".

[0004] Existing cable tensile strength testing devices generally adopt a box-type protective structure. Although this design provides basic safety protection, it has obvious limitations in actual operation: due to the limited internal space of the box, the operator's arm movement is severely restricted when clamping and adjusting the cable. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cable tensile strength testing device that adopts a manual lifting baffle design. The baffle is raised for easy operation during clamping and lowered to provide protection during testing. It is simple and safe to operate, ensuring testing efficiency while effectively preventing the risk of cable breakage and splashing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cable tensile strength testing device, comprising a base, wherein a testing mechanism is mounted on the base and used for cable tensile strength testing, the testing mechanism comprising:

[0007] The main components include servo motor ball screws fixed on the left and right sides of the upper end of the base, a lifting frame fixed between the sliders of the servo motor ball screws on both sides, a pressure sensor installed at the bottom of the lifting frame, and clamps on both the pressure sensor and the base for clamping the two ends of the cable.

[0008] The support assembly includes protective covers fixed to the left and right sides of the top of the base and used to protect the lifting frame. The front end of the protective cover is fixed with a guide rail.

[0009] The adjustment assembly includes a slide car mounted between two guide rails. A pull rod is slidably mounted through the lower end of the slide car. A guide plate is fixed to the upper end of the pull rod. The guide plate has symmetrical slots at both ends. Pins are slidably mounted through the left and right ends of the slide car, and the inner ends of the pins are slidably mounted with the slots. Springs are fitted on both sides of the upper end of the pull rod and located below the guide plate. A baffle is mounted on the slide car.

[0010] Preferably, the support assembly further includes an upper insertion hole at the upper end of the guide rail and a lower insertion hole at the lower end of the guide rail.

[0011] Preferably, the clamp includes a clamping seat fixed to the lower end of the pressure sensor and the upper end of the base. Inclined slot seats are fixed to the inner walls of both ends of the clamping seat. A chuck is slidably installed inside the inclined slot seat. A movable block is slidably installed laterally at the upper end of the chuck. A cylinder is installed at the upper end of the clamping seat, and the output end of the cylinder is connected to the movable block.

[0012] Preferably, the adjustment assembly further includes two guide wheels rotatably mounted at the left and right ends of the carriage and located inside the guide rail.

[0013] Preferably, the adjustment assembly further includes a mounting groove formed on the upper end of the carriage, and the lower end of the baffle is fixed inside the mounting groove by bolts.

[0014] Preferably, the adjustment assembly further includes a handle fixed to the front end of the carriage.

[0015] Beneficial effects

[0016] This invention provides a cable tensile strength testing device. Compared with the prior art, it has the following advantages:

[0017] 1. When the baffle position needs to be adjusted, the guide plate is moved downward by pulling the lever. The guide plate moves the pin inward through the slot, disengaging it from the insertion hole on the guide rail. The baffle can then be raised or lowered by adjusting the assembly. When clamping the cable, the operator raises the baffle, creating sufficient operating space between the baffle and the clamp, facilitating cable positioning and clamping. When entering the testing phase, the baffle is lowered to prevent debris from flying in case of accidental cable breakage during testing, ensuring operator safety and preventing external interference from affecting the testing process.

[0018] 2. After the adjustment component moves the baffle to the desired position, release the pulling rod. The spring's return pressure pushes the guide plate upward. The guide plate extends the pin outward through the slot, allowing it to be inserted into the corresponding upper or lower insertion hole to complete the locking. The adjustment process eliminates cumbersome steps and shortens the test preparation time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 - Figure 7 This utility model provides a technical solution: a cable tensile strength testing device, including a base 1, on which a testing mechanism 2 is disposed and used for cable tensile strength testing, the testing mechanism 2 including:

[0029] The main component 21 includes servo motor ball screws 211 fixed on the left and right sides of the upper end of the base 1. A lifting frame 212 is fixed between the sliders of the servo motor ball screws 211 on both sides. A pressure sensor 213 is installed at the bottom of the lifting frame 212. Both the pressure sensor 213 and the base 1 are equipped with clamps 214 for clamping both ends of the cable.

[0030] The support assembly 22 includes a protective cover 221 fixed on the left and right sides of the top of the base 1 and used to protect the lifting frame 212. The front end of the protective cover 221 is fixed with a guide rail 222.

[0031] The adjustment assembly 23 includes a slide 231 disposed between two guide rails 222. A pull rod 232 is slidably mounted through the lower end of the slide 231. A guide plate 233 is fixed to the upper end of the pull rod 232. The guide plate 233 has symmetrical slots 234 at both ends inside. Pins 235 are slidably mounted through the left and right ends of the slide 231, and the inner ends of the pins 235 are slidably mounted with the slots 234. Springs 236 are sleeved on both sides of the upper end of the pull rod 232 and located below the guide plate 233. A baffle 24 is installed on the slide 231.

[0032] In this embodiment, when it is necessary to adjust the position of the baffle 24, the guide plate 233 is moved downward by pulling the lever 232. The guide plate 233 drives the pin 235 to retract inward through the slot 234 and disengage from the insertion hole on the guide rail 222. Thus, the baffle 24 can be raised and lowered by adjusting the component 23.

[0033] When clamping the cable, the operator raises the baffle 24, which creates sufficient operating space between the baffle 24 and the clamp 214, facilitating the positioning and clamping of the cable. When entering the testing phase, the baffle 24 is lowered to prevent fragments from flying in case of accidental cable breakage during the test, ensuring the safety of the operator and avoiding external interference from affecting the testing process.

[0034] Specifically, the support component 22 also includes an upper insertion hole 223 opened at the upper end of the inside of the guide rail 222, and a lower insertion hole 224 opened at the lower end of the inside of the guide rail 222.

[0035] In this embodiment, after the adjusting component 23 drives the baffle 24 to rise and fall to the required position, the pulled rod 232 is released, and the guide plate 233 is pushed upward by the pressure of the spring 236. The guide plate 233 drives the pin 235 to extend outward through the slot 234, so that it is inserted into the corresponding upper insertion hole 223 or lower insertion hole 224 to complete the locking. The adjustment process eliminates cumbersome steps and shortens the test preparation time.

[0036] Specifically, the fixture 214 includes a clamp 2141 fixed to the lower end of the pressure sensor 213 and the upper end of the base 1. Both ends of the clamp 2141 are fixed with inclined slot seats 2142. A chuck 2143 is slidably installed inside the inclined slot seat 2142. A movable block 2144 is slidably installed on the upper end of the chuck 2143. A cylinder 2145 is installed on the upper end of the clamp 2141, and the output end of the cylinder 2145 is connected to the movable block 2144.

[0037] In this embodiment, the output end of the cylinder 2145 pushes the movable block 2144 to move laterally, causing the clamp 2143 to slide along the inclined surface trajectory of the inclined slot seat 2142, forming a self-locking clamping effect, which can adapt to the testing requirements of cables of different specifications.

[0038] Specifically, the adjustment assembly 23 also includes two guide wheels 238 that are rotatably mounted at the left and right ends of the carriage 231 and located inside the guide rail 222.

[0039] In this embodiment, the guide wheel 238 makes the lifting and lowering movement of the carriage 231 within the guide rail 222 more stable and smooth, significantly reducing the operating resistance and making it easier to adjust the position of the baffle 24.

[0040] Specifically, the adjustment assembly 23 also includes a mounting groove 239 formed on the upper end of the slide 231, and the lower end of the baffle 24 is fixed inside the mounting groove 239 by bolts.

[0041] In this embodiment, by opening an installation groove 239 at the upper end of the slide 231, the baffle 24 can be quickly disassembled and assembled using bolts.

[0042] Specifically, the adjustment assembly 23 also includes a handle 237 fixed to the front end of the carriage 231.

[0043] In this embodiment, the slide 231 can be moved smoothly along the guide rail 222 by simply pushing and pulling the handle 237, thereby precisely controlling the lifting and lowering position of the baffle 24.

[0044] The working principle and usage process of this utility model are as follows: First, the output end of the cylinder 2145 pushes the movable block 2144 to move laterally, which drives the clamp 2143 to slide along the inclined surface trajectory of the inclined slot seat 2142, forming a self-locking clamping effect, thereby clamping and fixing both the upper and lower ends of the cable.

[0045] Then, by pulling the lever 232, the guide plate 233 is moved downward. The guide plate 233 drives the pin 235 to retract inward through the slot 234, disengaging from the insertion hole on the guide rail 222. Thus, the baffle 24 can be lowered by adjusting the component 23. After the baffle 24 is raised or lowered to the desired position, the lever 232 is released. The pressure of the spring 236 pushes the guide plate 233 upward. The guide plate 233 drives the pin 235 to extend outward through the slot 234, so that it is inserted into the lower insertion hole 224 to complete the locking.

[0046] To prevent debris from flying out in the event of accidental cable breakage during testing, ensuring operator safety, and avoiding external interference from affecting the testing process;

[0047] Finally, the lifting frame 212 is driven by the servo motor ball screw 211 to perform precise lifting and lowering movements. The pressure sensor 213 at the bottom of the lifting frame 212 monitors the tensile force value in real time. Together with the clamp 214 on the base 1 and the pressure sensor 213, the cable is firmly clamped to ensure the accuracy of the test data.
