Description

Technical Field

[0001] The present application relates to cable defect detection technology, and in particular to a cable climbing device. Background Art

[0002] A cable-stayed bridge is a type of bridge that is composed of one or more main towers and cables to support the bridge deck. It is a structural system composed of compression towers, tension cables and bending beams.

[0003] At present, when the cable-stayed bridge is in normal use, it will be subjected to the pressure of dynamic loads such as vehicles on the bridge deck. At the same time, the cables of the cable-stayed bridge will be eroded by wind, rain and sunlight in the environment, resulting in defects such as local rust on the cables, and even cable breakage in severe cases. In the related technology, it is usually necessary to manually check the defects of each cable using a telescope or a high-altitude hanging basket so as to perform timely maintenance on the cables.

[0004] However, the method of using a telescope or a high-altitude hanging basket requires manual labor and is greatly affected by the environment, making it extremely inconvenient to detect cable defects. Utility Model Content

[0005] In view of this, the present application provides a climbing rope device, which aims to solve the problem that the detection of defects in the existing cable-stayed bridge cables relies on manual labor and is greatly affected by the environment, resulting in inconvenient detection.

[0006] In order to achieve the above-mentioned purpose, the present application provides a climbing rope device, which adopts the following technical solutions:

[0007] The present application provides a cable climbing device for climbing on a cable, comprising: a mounting frame, a power assembly and an auxiliary clamping assembly;

[0008] The mounting frame is used to provide a mounting position for the magnetic flux leakage detection device, and the mounting frame is used to be passed through the cable;

[0009] The power assembly is arranged on the mounting frame and abuts against the cable, and the power assembly is used to drive the mounting frame to move along the length direction of the cable;

[0010] The auxiliary clamping assembly is arranged at the bottom of the mounting frame, and the auxiliary clamping assembly abuts against the cable and is used to clamp the cable on the auxiliary clamping assembly.

[0011] By adopting the above technical solution, when the above climbing device is used, the leakage magnetic detection device can be first installed on the mounting frame, and then the mounting frame can be installed on the cable, so that the cable passes through the mounting frame, and the auxiliary clamping component is operated to abut against the cable, and then the component is started. The power component drives the mounting frame to move along the length direction of the cable, and the leakage magnetic detection device on the mounting frame can perform defect detection on the cable. There is no need to use a telescope or other means to observe the cable, which greatly improves the convenience of detecting cable defects.

[0012] In addition, the auxiliary clamping assembly also adds more support points to the installation frame, making the climbing rope device more stable when moving and less affected by factors such as wind speed and sunlight in the environment, thereby improving stability.

[0013] In a possible implementation, the auxiliary clamping assembly includes a plurality of auxiliary rods and a plurality of springs;

[0014] The same end of each auxiliary rod is rotatably connected to the bottom of the mounting frame, and the other end of each auxiliary rod is abutted against the cable. Multiple springs correspond to multiple auxiliary rods one by one, and the auxiliary rods are also connected to the mounting frame through the springs. The springs are used to provide pulling force to the auxiliary rods so that the ends of the auxiliary rods away from the mounting frame are pressed against the cable.

[0015] Here, when operating the auxiliary clamping assembly to abut the cable, the auxiliary rod can be dragged away from one end of the mounting frame. After the cable is passed through the mounting frame, each auxiliary rod can be loosened. Under the action of the spring, the end of the auxiliary rod away from the mounting frame automatically abuts the cable, and under the action of the spring tension, the cable is pressed tightly, providing more support points for the movement of the climbing device.

[0016] In a possible implementation, the auxiliary clamping assembly further includes an auxiliary wheel, which is disposed at the other end of the auxiliary rod, and is used to abut against the cable, and the auxiliary wheel can rotate relative to the cable.

[0017] Here, the auxiliary wheel can rotate relative to the cable, reducing the friction between the end of the auxiliary rod and the cable, making it easier and less power consuming when moving.

[0018] In addition, an auxiliary wheel is provided at the end of the auxiliary rod, which can effectively reduce the wear of the cable when the auxiliary rod moves along the cable, reduce the wear rate of the cable, and thus play an effect of protecting the cable.

[0019] In a possible implementation manner, the auxiliary rod is a hollow rod.

[0020] By adopting the above technical solution, the hollow structure helps to reduce the weight of the auxiliary rod, so that the overall weight of the climbing device is smaller, while achieving weight reduction while ensuring the load-bearing capacity and reducing costs.

[0021] In a possible implementation, the power assembly includes at least two driving wheels and at least two motors;

[0022] The driving wheels are arranged on the mounting frame and rotate relative to the mounting frame. Each driving wheel is used to abut against the cable. The motor is connected to the driving wheels one by one to drive the driving wheels to rotate so that the mounting frame moves along the length direction of the cable.

[0023] By adopting the above technical solution, when the power component drives the installation frame to move along the length direction of the cable, the output end of the motor drives the driving wheel to rotate, and the driving wheel rolls on the cable, thereby driving the installation frame to move. This structure is simple, easy to operate, and convenient to maintain.

[0024] In a possible implementation manner, the motor is a direct current motor.

[0025] By adopting the above technical solution, the DC motor has better starting characteristics and speed regulation characteristics, and has a large torque, which can better drive the installation frame to move. Moreover, since the movement of the installation frame on the cable is not uniform, the speed and direction need to be adjusted according to detection, and the DC motor can better respond to control.

[0026] In a possible implementation, the power assembly further includes at least two driven wheels, which are disposed on the mounting frame and rotate relative to the mounting frame, and each of the driven wheels is used to abut against the cable.

[0027] By adopting the above technical solution, when the driving wheel drives the installation frame to move, the driven wheel can follow the installation frame and roll on the cable at the same time. The driven wheel and the driving wheel together provide support points for the movement of the installation frame, which can make the movement of the installation frame more stable.

[0028] In a possible implementation, the mounting frame includes a frame body and a frame side cover; the power assembly and the auxiliary clamping assembly are both arranged on the frame body, and the frame side cover is detachably connected to the frame body.

[0029] By adopting the above technical solution, the installation frame is installed on the cable. When the cable is passed through the installation frame, the frame side cover can be removed, and the frame body can be moved from one side of the cable. After the cable is passed through the frame body, the frame side cover can be reinstalled on the frame body, which can facilitate the installation of the installation frame and make the operation simple.

[0030] In a possible implementation, the frame side cover is connected to the frame body by bolts.

[0031] By adopting the above technical solution, the bolt connection belongs to a fastener connection, which has the characteristics of easy disassembly and assembly, and can facilitate and quickly disassemble the frame side cover.

[0032] In addition, the bolt connection can increase the pre-tightening force to separate the frame side cover from the frame body when the frame is installed and prevent the frame side cover from being lost.

[0033] In a possible implementation, the device further includes a controller;

[0034] The controller is in communication connection with the power assembly, and the controller is configured to receive a control signal and drive the power assembly to start and stop.

[0035] By adopting the above technical solution, the control signal is remotely transmitted to the controller on the ground, and the controller then controls the start and stop of the power component. The defect detection of the cable can be completed remotely, which reduces the risk and is less affected by environmental factors.

[0036] In summary, this application has the following beneficial effects:

[0037] 1. The power component drives the installation frame to move on the cable, and the installation frame can drive the leakage magnetic detection device to detect defects in the cable. The overall climbing device shakes with the shaking of the cable. It can be understood that the climbing device is fixed relative to the cable, which can improve the stability of the detection. There is no need to use a telescope or other means to observe cable defects, and it is less affected by environmental factors, which greatly facilitates the defect detection of the cable.

[0038] 2. The auxiliary wheels in the auxiliary clamping assembly also add more support points to the installation frame, making the climbing device more stable when moving and less affected by factors such as wind speed and sunshine in the environment, thereby improving stability. In addition, the auxiliary wheels can effectively reduce the wear of the cable when the auxiliary rod moves along the cable, reducing the wear rate of the cable, thereby protecting the cable.

[0039] 3. The control signal is transmitted remotely to the controller on the ground, and the controller controls the start and stop of the power component. The defect detection of the cable can be completed remotely, which reduces the risk and is less affected by environmental factors. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] A cable-stayed bridge is a type of bridge that is composed of one or more main towers and cables to support the bridge deck. It is a structural system composed of compression towers, tension cables and bending beams.

[0062] At present, when a cable-stayed bridge is in normal use, it will be subjected to the pressure of dynamic loads such as vehicles on the bridge deck. At the same time, the cables of the cable-stayed bridge will be eroded by wind, rain and sunlight in the environment, resulting in defects such as local rust of the cables, and even cable breakage in severe cases.

[0063] In the related art, it is usually necessary to use a telescope or an aerial hanging basket to check the defects of each cable so as to perform timely maintenance on the cables.

[0064] The method of using a telescope is to manually use a telescope on the ground to observe the cables at a high altitude. The method of using an aerial basket is to use a crane to lift the inspectors to the cables, and then manually inspect the cables.

[0065] It is very necessary to detect defects in cables, especially the defects in the steel wires inside the cables. Regular inspection and maintenance of cables can significantly improve the safety of bridges.

[0066] However, the use of telescopes or aerial baskets is greatly affected by the environment. When encountering windy and rainy weather, it will greatly affect the progress of work. For example, the shaking of the cable caused by wind and rain will make the telescope observation unclear, and there is a certain degree of danger.

[0067] Based on this, an embodiment of the present application provides a climbing cable device. The climbing cable device is provided with an installation frame, a power component and an auxiliary clamping component. The installation frame is used to provide an installation position for a leakage magnetic detection device, and the installation frame is used to be passed through the cable; the power component is arranged on the installation frame and abuts against the cable, and the power component is used to drive the installation frame to move along the length direction of the cable; the auxiliary clamping component is arranged at the bottom of the installation frame, and the auxiliary clamping component abuts against the cable and is used to clamp the cable on the auxiliary clamping component. When using the climbing cable device to perform defect detection on the cable, the cable is first passed through the installation frame, and the auxiliary clamping component is used to clamp the cable on the auxiliary clamping component, and then the power component is operated to start, and the power component drives the installation frame to move, and the leakage magnetic detection device on the installation frame can remotely perform defect detection on the cable, and the defects of the cable can be observed without using a telescope. At the same time, the climbing cable device can also work normally in windy and rainy weather, and is less affected by the environment. The problem that the detection of defects in the existing cable-stayed bridge steel cables relies on manual labor, is greatly affected by the environment, and causes inconvenience in detection is solved.

[0068] Figure 1 This is a schematic diagram of the structure of the climbing device provided in the embodiment of the present application. It should be noted that: Figure 1 The schematic diagram of each component of the climbing rope device is shown. The specific structure of the remaining components of the climbing rope device is not limited to Figure 1 of examples.

[0069] The present application is described in detail below with reference to the accompanying drawings and specific embodiments:

[0070] Reference Figure 1 As shown, a rope climbing device provided in an embodiment of the present application includes a mounting frame 100 , a power assembly 200 and an auxiliary clamping assembly 300 .

[0071] The mounting frame 100 is used to provide an installation position for a magnetic flux leakage detection device. The magnetic flux leakage detection device is a well-known technology in the field. The magnetic flux leakage detection device is a device applied to non-destructive testing technology, which is used to detect defects on the surface or near the surface of the cable. When the cable is magnetized, if there is a material discontinuity on the surface and near the surface (the homogeneous state or density of the material is destroyed), the direction of the magnetic field will change at the discontinuity, and magnetic poles will be generated where the magnetic lines of force leave and enter the surface of the cable, forming a leakage magnetic field. People can find defects by detecting changes in the leakage magnetic field. It is understandable that the magnetic flux leakage detection device first magnetizes part of the cable, and then detects the leakage magnetic field to find the location of the cable defect.

[0072] The installation method of the magnetic flux leakage detection device is not limited here. It only needs to be installed on the installation frame 100 and move along the cable with the installation frame 100 to complete the defect detection of the cable.

[0073] The mounting frame 100 is used to be passed through the cable, the power component 200 is arranged on the mounting frame 100 and abuts against the cable, the power component 200 is used to drive the mounting frame 100 to move along the length direction of the cable, and the auxiliary clamping component 300 is arranged at the bottom of the mounting frame 100, the auxiliary clamping component 300 abuts against the cable and is used to clamp the cable on the auxiliary clamping component 300.

[0074] In the above embodiment, when using the above-mentioned climbing rope device, the leakage magnetic detection device can be first installed on the mounting frame 100, and then the mounting frame 100 can be installed on the cable, so that the cable passes through the mounting frame 100, and the auxiliary clamping component 300 is operated to abut against the cable, and then the component is started. The power component 200 drives the mounting frame 100 to move along the length direction of the cable. The leakage magnetic detection device on the mounting frame 100 can perform defect detection on the cable, and there is no need to use a telescope or the like to observe the cable, which greatly improves the convenience of detecting cable defects.

[0075] In addition, the auxiliary clamping assembly 300 also adds more support points to the mounting frame 100, so that the climbing rope device is more stable when moving and is less affected by factors such as wind speed and sunlight in the environment, thereby improving stability.

[0076] In a possible implementation, the auxiliary clamping assembly 300 includes a plurality of auxiliary rods 310 and a plurality of springs 320 .

[0077] The same end of each auxiliary rod 310 is rotatably connected to the bottom of the mounting frame 100, and the other end of each auxiliary rod 310 is abutted against the cable. Specifically, multiple auxiliary rods 310 are evenly distributed along the circumference of the cable. There are four auxiliary rods 310, and the four auxiliary rods 310 are evenly arranged at the four corners of the bottom of the mounting frame 100, which helps to evenly distribute the support points.

[0078] The plurality of springs 320 correspond to the plurality of auxiliary rods 310 one by one. The auxiliary rods 310 are also connected to the mounting frame 100 via the springs 320. The springs 320 are used to provide tension to the auxiliary rods 310 so that the ends of the auxiliary rods 310 away from the mounting frame 100 are pressed against the cables.

[0079] Specifically, one end of the spring 320 is connected to the middle section of the auxiliary rod 310, and the other end is connected to the bottom of the mounting frame 100 close to the cable direction, so that the end of the auxiliary rod 310 away from the mounting frame 100 is pressed against the cable.

[0080] Here, when operating the auxiliary clamping assembly 300 to abut against the cable, the auxiliary rod 310 can be dragged away from one end of the mounting frame 100. After the cable is passed through the mounting frame 100, each auxiliary rod 310 is loosened. Under the action of the spring 320, the end of each auxiliary rod 310 away from the mounting frame 100 automatically abuts against the cable, and under the action of the tension of the spring 320, the cable is pressed tightly, providing more support points for the movement of the climbing device. At the same time, multiple auxiliary rods 310 are helpful in preventing the climbing device from spiraling or tipping over when moving along the cable.

[0081] In a possible implementation, in order to reduce the friction between the end of the auxiliary rod 310 and the cable, the auxiliary clamping assembly 300 also includes an auxiliary wheel 330, which is arranged at the other end of the auxiliary rod 310. The auxiliary wheel 330 is used to abut against the cable, and the auxiliary wheel 330 can rotate relative to the cable.

[0082] The auxiliary wheel 330 can rotate relative to the cable, which can effectively reduce the wear of the cable when the auxiliary rod 310 moves along the cable, reduce the wear rate of the cable, and thus play an effect of protecting the cable.

[0083] In a possible implementation, in order to reduce weight and lower costs, the auxiliary rod 310 is a hollow rod. The hollow structure helps to reduce the weight of the auxiliary rod 310, so that the overall weight of the climbing rope device is smaller, while achieving weight reduction while ensuring the load-bearing capacity and reducing costs.

[0084] In a possible implementation, the power assembly 200 includes at least two driving wheels 210 and at least two motors 220 .

[0085] The driving wheels 210 are arranged on the mounting frame 100 and rotate relative to the mounting frame 100. Each driving wheel 210 is used to abut against the cable. The motor 220 is connected to the driving wheel 210 in a one-to-one correspondence to drive the driving wheel 210 to rotate so that the mounting frame 100 moves along the length direction of the cable. The driving wheels 210 are evenly distributed along the circumference of the cable, which helps to prevent the climbing device from tipping over.

[0086] Here, when the power component 200 drives the installation frame 100 to move along the length direction of the cable, the output end of the motor 220 drives the driving wheel 210 to rotate, and the driving wheel 210 rolls on the cable, thereby driving the installation frame 100 to move. This structure is simple, easy to operate, and convenient for maintenance.

[0087] In a possible implementation, the motor 220 is a DC motor 220. The DC motor 220 has better starting characteristics and speed regulation characteristics, and has a large torque, and can better drive the installation frame 100 to move. In addition, since the movement of the installation frame 100 on the cable is not uniform, the speed and direction need to be adjusted according to the detection progress, and the DC motor 220 can better respond to the control.

[0088] In a possible implementation, the power assembly 200 further includes at least two driven wheels 230, which are disposed on the mounting frame 100 and rotate relative to the mounting frame 100, and each driven wheel 230 is used to abut against the cable. Each driven wheel 230 is also evenly distributed along the circumference of the cable to improve the stability of the cable climbing device.

[0089] In the above embodiment, when the driving wheel 210 drives the installation frame 100 to move, the driven wheel 230 can move with the installation frame 100 and roll on the cable at the same time. The driven wheel 230 and the driving wheel 210 jointly provide a support point for the movement of the installation frame 100, which can make the movement of the installation frame 100 more stable.

[0090] In a possible embodiment, an odometer (not shown in the drawings) is further included. The odometer is arranged on the driving wheel 210 and can calculate the number of rotations of the driving wheel 210. It can be understood that when the climbing rope device is located on the cable and moves, the displacement distance of the climbing rope device can be obtained by calculating the number of rotations of the driving wheel 210 and the diameter of the driving wheel 210. When the leakage magnetic detection device finds that there is a defect in the cable, the odometer records the number of rotations of the driving wheel 210, which is convenient for accurately finding the defect location and making timely repairs.

[0091] In a possible implementation, the mounting frame 100 includes a frame body 110 and a frame side cover 120 ; the power assembly 200 and the auxiliary clamping assembly 300 are both disposed on the frame body 110 , and the frame side cover 120 is detachably connected to the frame body 110 .

[0092] Specifically, the frame side cover 120 is connected to the frame body 110 by bolts.

[0093] In the above embodiment, when the mounting frame 100 is installed on the cable and the cable is passed through the mounting frame 100, the frame side cover 120 can be removed, and the frame body 110 can be moved from one side of the cable. After the cable is passed through the frame body 110, the frame side cover 120 can be reinstalled on the frame body 110. This can facilitate the installation of the mounting frame 100 and make the operation simple. The bolt connection is a fastener connection, which is easy to disassemble and install, and the frame side cover 120 can be easily and quickly removed.

[0094] In addition, the bolt connection can increase the pre-tightening force to prevent the frame side cover 120 from being separated from the frame body 110 and prevent the frame side cover 120 from being lost when the mounting frame 100 is not in operation.

[0095] In a possible implementation, a controller (not shown in the drawings) is also included.

[0096] The controller is in communication connection with the power assembly 200 , and the controller is configured to receive a control signal and drive the power assembly 200 to start and stop.

[0097] In the above embodiment, the control signal can be remotely transmitted to the controller on the ground, and the controller then controls the start and stop of the power assembly 200. There is no need to climb up to observe, and the defect detection of the cable can be completed remotely, which reduces the danger and is less affected by environmental factors.

[0098] In a possible implementation, the control signal is transmitted by using 2.4G wireless communication. 2.4 GHz ISM (Industry Science Medicine) is a publicly used wireless frequency band with a large signal transmission range and anti-interference performance, which facilitates remote control of the climbing device.

[0099] The implementation principle of a climbing rope device in an embodiment of the present application is as follows: when using the climbing rope device to detect defects in the cable, the cable is first passed through the installation frame 100, and the auxiliary clamping component 300 is used to clamp the cable on the auxiliary clamping component 300, and then the power component 200 is started by remote control, and the power component 200 drives the installation frame 100 to move. The leakage magnetic detection device on the installation frame 100 can remotely detect defects in the cable, and the defects of the cable can be observed without using a telescope. At the same time, the climbing rope device can also work normally in windy and rainy weather, and is less affected by the environment. This solves the problem that the existing cable-stayed bridge cable defect detection uses a telescope for observation or an artificial hanging basket method, which is greatly affected by the environment and causes inconvenience in detection.
