Description

Technical Field

[0001] This utility model belongs to the field of double-layer wire testing technology, specifically a double-layer wire strength testing device. Background Technology

[0002] Double-layer guy wire strength testing equipment is a specialized device used to test the strength of guy wires such as cables, ropes, and steel wires. It is widely used in construction, bridges, power, communications, shipbuilding and other fields. Guy wires play an important role in supporting and transmitting forces in various engineering structures, and their strength is directly related to the safety and reliability of the structure. Therefore, testing the strength of guy wires is a key step to ensure project quality and safe use.

[0003] Existing double-layer wire strength testing equipment has the following main shortcomings:

[0004] Existing double-layer wire strength testing equipment struggles to precisely control the clamping force when dealing with double-layer wires of varying specifications, such as thickness, material, and resulting hardness and elasticity. Excessive force can damage the wire before testing, affecting the true strength test results. Insufficient force can cause the wire to loosen or even detach during testing, interrupting the process and preventing the acquisition of complete and accurate results. Furthermore, the vibration of the tested wire severely impacts the accuracy and precision of the measurement results, requiring multiple measurements and calibrations to obtain relatively reliable data, thus reducing the overall efficiency of the testing work.

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution:

[0024] A double-layer wire strength testing device, comprising:

[0025] A base 1 has a controller 2 located on one side near the front. A buffer structure 3 is located at the center of the upper surface of the base 1. Lifting structures 4 are located on both sides of the center of the upper surface of the buffer structure 3. Horizontal plates 5 are located at the upper and lower centers of the two lifting structures 4. Stabilizing blocks 6 are located at the center of the lower surface of the upper horizontal plate 5 and the center of the upper surface of the lower horizontal plate 5. Clamping structures 7 are located at the center of the lower surface of the upper stabilizing block 6 and the center of the upper surface of the lower stabilizing block 6. A second mounting bracket 8 is located at the center of one side of the lifting structure 4. The buffer structure 3 includes four dampers 301 and four dampers 301. The four dampers 301 are arranged in a rectangular pattern at the four opposite corners of the upper surface of the base 1. Each of the four dampers 301 is fitted with a compression spring 302 on its outer side. The upper surface of the four compression springs 302 is provided with a placement platform 303. When the equipment vibrates or is impacted by external forces during operation, the compression springs 302 can absorb and buffer part of the impact force and reduce the transmission of vibration through elastic deformation. The dampers 301 further consume the vibration energy, making the components on the placement platform 303 run more stably, reducing the interference that vibration may cause to the detection, and extending the overall service life of the equipment.

[0026] The two lifting structures 4 include two first frames 401, which are respectively located on both sides of the center of the upper end face of the placement platform 303. Each of the two first frames 401 has a first groove 402 at the center of one side wall. Each of the two first grooves 402 has a first connecting block 403 at its center. Each of the two first grooves 402 has a first lead screw 404 located near the upper center of its center. One end of each lead screw 404 passes through the upper end face of the two first connecting blocks 403 and extends to the lower end face of the two first connecting blocks 403, and each end is fixedly connected to a second lead screw 405. The two first lead screws 404 and the two second lead screws 405 are threaded together. Conversely, two horizontal plates 5 are threaded onto the outer walls of two first lead screws 404 and two second lead screws 405, respectively. The other ends of the two first lead screws 404 pass through the inner walls of the two first slide grooves 402 and the inner walls of the two first frames 401, respectively, and are connected to the upper end faces of the two first frames 401. Each end is fixedly connected to a pulley 407. A belt is fitted onto the outer wall of the two pulleys 407. A first mounting bracket 406 is provided at the center of the upper end face of one side of the first frame 401. A first motor 408 is provided at the center of the upper end face of the first mounting bracket 406. The output end of the first motor 408 is fixedly connected to one end of the pulley 407 on one side.

[0027] The first motor 408 is started to drive the pulley 407 connected to it to rotate. Since the two pulleys 407 are connected by a belt, they rotate synchronously. The rotation of the pulleys 407 drives the first lead screw 404 connected to it to rotate. The threads of the first lead screw 404 and the second lead screw 405 are opposite, and the horizontal plate 5 is threaded on the outer wall of the first lead screw 404 and the second lead screw 405. Therefore, when the first lead screw 404 rotates, it will drive the horizontal plate 5 to move up and down along the first lead screw 404 and the second lead screw 405, thereby realizing the function of adjusting the distance between the upper and lower horizontal plates 5 to meet the testing requirements of double-layer wires of different specifications. If a longer double-layer wire needs to be tested, the distance between the upper and lower horizontal plates 5 can be increased through the lifting structure 4.

[0028] The two clamping structures 7 include two second frames 701, which are respectively located at the center of the lower end face of the upper stabilizing block 6 and the center of the upper end face of the lower stabilizing block 6. A second sliding groove 702 is provided at the center of the lower end face of the upper second frame 701 and the center of the upper end face of the lower second frame 701. A buzzer 711 is provided at the center of the upper end face of the second mounting bracket 8, and a transmission module 710 is provided at the center of the upper end face of the buzzer 711. A second connecting block 703 is provided at the center of the interior of each of the two second sliding grooves 702. A second motor 704 is provided at the lower end of the rear end face of the upper second frame 701 and the upper end of the rear end face of the lower second frame 701. The output ends of the two second motors 704 pass through the two second frames 701 sequentially. The rear end face of 01 and the rear end face of the two second slide grooves 702 are connected to the interior of the two second slide grooves 702, and the ends of the two third lead rods 705 are fixedly connected. One end of each of the two third lead rods 705 passes through the rear end face of the two second connecting blocks 703 and is connected to the front end face of the two second connecting blocks 703, and the ends of the two third lead rods 705 and the two fourth lead rods 706 are fixedly connected. The outer walls of the two third lead rods 705 and the two fourth lead rods 706 are threaded with sliders 707. The two sliders 707 at the front end face and the two sliders 707 at the rear end face are provided with slots 709. The center of the interior of each of the four sliders 707 is provided with a pressure detector 708. The two third lead rods 705 and the two fourth lead rods 706 are respectively arranged with opposite threads.

[0029] The second motor 704 is activated to drive the third lead screw 705 to rotate. The third lead screw 705 and the fourth lead screw 706 are threaded with sliders 707 on their outer walls. Due to the principle of threaded transmission, the rotation of the third lead screw 705 and the fourth lead screw 706 causes the sliders 707 to move relative to each other in the second slide groove 702. The slots 709 on the sliders 707 are used to hold the double-layer wire at the corresponding positions, thereby achieving a firm clamping of the double-layer wire. At the same time, the pressure detector 708 inside the sliders 707 can detect the pressure applied to the double-layer wire during the clamping process, so that the clamping force is appropriate, ensuring that the double-layer wire will not fall off during the detection process, and will not be damaged due to excessive clamping force.

[0030] The working principle of this utility model is as follows: By placing the double-layered pull wire to be tested between the upper and lower horizontal plates 5, the second motor 704 is started to move the slider 707 further. The corresponding position of the double-layered pull wire is locked by the slot 709 on the slider 707. During the clamping process, the pressure detector 708 inside the slider 707 detects the pressure applied to the double-layered pull wire in real time. If the pressure is too high or too low, the operation of the second motor 704 can be adjusted according to the feedback of the pressure detector 708, thereby adjusting the movement of the slider 707 to ensure that the clamping force on the double-layered pull wire is appropriate. After the double-layered pull wire is firmly clamped,

[0031] Throughout the testing process, the four dampers 301 and compression springs 302 of the buffer structure 3 are pre-installed and ready to respond to any vibrations or external impacts that may occur during equipment operation, ensuring the stability of the placement platform 303, providing a stable foundation for subsequent testing operations, absorbing and buffering the vibrations generated during testing operations and any impact forces that may be applied from the outside, ensuring stable equipment operation, and avoiding interference with the testing results from vibrations. Based on the approximate specifications of the double-layer pulley to be tested, the first motor 408 is started, driving the connected pulley 407 to rotate. Due to belt drive, the two pulleys 407 rotate synchronously, thereby driving the connected first lead screw 404 to rotate. The first lead screw 404 and the second lead screw 405 have opposite threads, and the horizontal plate 5 is threaded onto the outer wall of the first lead screw 404 and the second lead screw 405. Therefore, the rotation of the first lead screw 404 drives the horizontal plate 5 to move up and down along the first lead screw 404 and the second lead screw 405, adjusting the distance between the upper and lower horizontal plates 5 to a suitable position to accommodate the length of the double-layer pull wire to be tested. It is equipped with a buzzer 711 and an audible and visual prompting system. When the equipment encounters an abnormal situation during the testing process, the buzzer 711 can promptly issue an alarm to remind the operator. The transmission module 710 can also transmit key data to the designated equipment end, which is convenient for the operator to analyze and process, improving the ease of use and applicability of the equipment.

[0032] Furthermore, the control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0033] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
