Description

Technical Field

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

[0002] Bridge cable is a kind of steel wire rope fixed on the front railing. It is generally used to protect people crossing the bridge and prevent them from falling under the bridge. The cable is hard and not easy to break. It has the ability to provide stable support and can carry heavy objects. With the rapid development of modern life, bridge designs are appearing more and more in our lives, and the situations in which cables need to be used for protection are also gradually increasing.

[0003] Bridge cables need to undergo multiple performance tests before they are manufactured and shipped out of the factory. Only when they meet a certain qualification coefficient can they be shipped out of the factory. When conducting a tensile test on bridge cables, existing tensile test devices generally perform tensile tests at the same level at both ends.

[0004] For example, the Chinese utility model patent with patent number 202320591145.8 provides a bridge cable traction force detection device. When in use, the two ends of the cable to be tested are respectively connected to the tension sensors of the two movable plates, and then the motor is started to drive the screw to rotate. The screw drives the two movable plates to move relative to each other, thereby tensioning the cable to detect the tension through the tension sensor.

[0005] However, when bridge cables are actually used, the connection points at both ends of the cables are generally not at the same height. When the cables are in an inclined state, their own performance will change to a certain extent due to their own gravity and other factors. The existing bridge cable tension detection device is not convenient for simulating the stress conditions of bridge cables in an inclined state and performing tension detection thereon, which makes it impossible to simulate the actual use of bridge cables well, making the test data relatively one-sided and unconvincing.

[0040] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0041] Example:

[0042] like Figure 1 , 2 As shown, the utility model provides a bridge cable detection device for detecting the tension of a cable to be tested 106, comprising a frame 101, a mounting frame 201 is arranged on the frame 101, a first winding assembly is arranged on the frame 101, and one end of the cable to be tested 106 is wound by the first winding assembly. The first winding assembly comprises a support frame 102 fixedly arranged on the frame 101, a first winding roller 103 is rotatably arranged on the support frame 102, one end of the cable to be tested 106 is wound on the first winding roller 103, a first winding motor 104 is fixedly arranged on the support frame 102, and the output shaft of the first winding motor 104 is connected to the first winding roller 103.

[0043] When in use, one end of the cable 106 to be tested can be wound around the first winding roller 103, and the first winding motor 104 can be controlled to start and drive the first winding roller 103 to rotate. During the rotation, the first winding roller 103 can tighten one end of the cable 106 to be tested, and the other end of the cable 106 to be tested is restricted by other mechanisms, so that the cable 106 to be tested is in a tensioned state, so as to facilitate the detection of the tension of the cable 106 to be tested.

[0044] like Figure 3 , 4 As shown, in the present embodiment, a second winding assembly is movably arranged on the mounting frame 201, and the other end of the cable to be tested 106 is wound up by the second winding assembly. The second winding assembly includes a lifting block 202 movably arranged on the mounting frame 201, and a rotatable second winding roller 203 is arranged on the lifting block 202. The other end of the cable to be tested 106 is wound up on the second winding roller 203. A second winding motor 205 is arranged on the lifting block 202, and the output shaft of the second winding motor 205 is connected to the second winding roller 203.

[0045] By controlling the second winding motor 205 to start and drive the second winding roller 203 to rotate, the second winding roller 203 can wind up the other end of the cable to be measured 106 during the rotation process, and because the cable to be measured 106 is tensioned by the winding force of the first winding component, the second winding roller 203 can apply tension to the cable to be measured 106 when it rotates, thereby facilitating the detection of the tension of the cable to be measured 106.

[0046] like Figure 1 , 3 As shown, in this embodiment, a first limit plate 105 is provided on the support frame 102, a second limit plate 204 is provided on the lifting block 202, and both ends of the cable 106 to be tested are respectively wound on the first limit plate 105 and the second limit plate 204. When winding the cable 106 to be tested, the cable 106 to be tested can be wound around the first winding roller 103 and the second winding roller 203 for several turns, and then the cable 106 to be tested can be wound around the first limit plate 105 and the second winding roller 203 for several turns, so as to effectively avoid the two ends of the cable 106 to be tested from slipping, thereby improving the accuracy of detection.

[0047] like Figure 1 , 3 As shown, in this embodiment, a driving assembly connected to the second winding assembly is provided on the mounting frame 201, and the second winding assembly is driven to rise and fall by the driving assembly. The driving assembly includes a screw rod 207 rotatable along its axis and arranged on the mounting frame 201. The screw rod 207 passes through the lifting block 202 and is screwed thereto. A lifting motor 208 is provided on the mounting frame 201, and the output shaft of the lifting motor 208 is connected to the screw rod 207.

[0048] The lifting motor 208 can be controlled to start and drive the screw rod 207 to rotate. The screw rod 207 can drive the lifting block 202 to rise and fall through the threaded fit during the rotation process. The lifting block 202 can drive the second winding roller 203 to rise and fall during the lifting process, so that the cable 106 to be tested is in an inclined state for testing, so as to simulate the stress condition of the cable 106 to be tested in real use. In addition, in some embodiments, the driving component can also control the lifting block 202 to rise and fall through a hydraulic lifting rod or an electric lifting rod, etc., which can be selected according to actual conditions.

[0049] like Figure 1 , 3 As shown in Figure 4, in this embodiment, a tension detection component for detecting the tension applied to the second winding component when winding the tested cable 106 is provided on the mounting frame 201, and the tension detection component includes a torque sensor provided on the output shaft of the second winding motor 205, and the torque sensor is connected to the second winding roller 203. A first display 206 is provided on the mounting frame 201, and the first display 206 is electrically connected to the torque sensor.

[0050] When the second winding motor 205 controls the rotation of the second winding roller 203, the tension generated by the tested cable 106 can be obtained according to the torque applied to the second winding roller 203, and the obtained data can be transmitted to the first display 206 for display, so that the staff can quickly obtain the test data. When the tension applied to the tested cable 106 reaches the qualified level and there is no obvious change in the tested cable 106, it indicates that the tested cable 106 has passed the tensile test. Among them, the model and installation method of the torque sensor, the electrical connection method and signal transmission method of the torque sensor and the first display 206, and the data calculation method are all common technical means of those skilled in the art, and will not be repeated here.

[0051] like Figure 1 , 2 As shown, in this embodiment, a support frame 301 is also provided on the frame 101, and an electric slider 302 on which a second display 304 can be raised and lowered is provided on the support frame 301. A pressure tester 303 is provided on the electric slider 302, and the pressure tester 303 is electrically connected to the second display 304, and the cable 106 to be tested is wound around the pressure tester 303.

[0052] The lifting of the electric slider 302 can also be driven by a hydraulic push rod, a chain drive or a ball screw. When the first winding roller 103 and the second winding roller 203 are at different height levels, the cable 106 to be tested will provide an upward pressure to the pressure tester 303. The pressure tester 303 analyzes the pressure and displays it through the second display 304. The tensile strength of the cable 106 to be tested at different tilt angles and different tensions is recorded and calculated, making the test data more comprehensive and improving the functionality of the device. Among them, the model and installation method of the pressure tester 303, the electrical connection method and signal transmission method of the pressure tester 303 and the second display 304, and the data calculation method are all common technical means of those skilled in the art, and will not be repeated here.

[0053] Specific usage and beneficial effects of the utility model:

[0054] When the device is in use, the lifting motor 208 is controlled to start and drive the screw rod 207 to rotate. During the rotation process, the screw rod 207 drives the second winding roller 203 and the second winding motor 205 to rise and fall on the mounting frame 201 through the threaded cooperation with the lifting block 202, so as to adjust the height of the second winding roller 203, so that a height difference is formed between the first winding roller 103 and the second winding roller 203, and then the two ends of the cable 106 to be measured are respectively wound around the first winding roller 103 and the second winding roller 203, and the first winding roller 103 is controlled to rotate to wind up one end of the cable 106 to be measured, so that the cable 106 to be measured is in a tensioned state, and then the second winding roller 203 rotates to adjust the height of the second winding roller 203. The other end of the cable 106 to be tested is wound up, and the second winding roller 203 detects the tension applied to the cable 106 to be tested through the torque sensor during the winding of the cable 106, and transmits the detection data to the first display 206 for display. When the tension applied to the cable 106 to be tested reaches a qualified level and there is no obvious change in the cable 106 to be tested, it indicates that the tensile force test of the cable 106 to be tested is qualified. The tension test of the cable 106 to be tested is relatively convenient, and it can simulate the stress conditions of the bridge cable under different tilt angles and perform tension test on it, thereby simulating the actual use of the bridge cable well, making the test data more convincing.
