Description

Technical Field

[0001] This utility model relates to the field of wire rope monitoring, and in particular to a real-time wear monitoring and early warning device for crane wire ropes. Background Technology

[0002] A crane is a mechanical device used for vertical lifting and horizontal transport of heavy objects. Its core function is to lift, transport, and install materials using a lifting hook or other lifting tools. It mainly consists of a metal structure (such as a bridge frame or boom), a hoisting mechanism, a running mechanism, and a control system. It is widely used in construction, port terminals, factory workshops, logistics warehousing, and other scenarios. There are different types, such as bridge cranes, tower cranes, truck cranes, and crawler cranes, to meet different operational needs.

[0003] The wire rope of a crane is mainly used to connect the hook to the lifting equipment. It bears the weight of the load through its own strength and flexibility, realizing the vertical lifting and horizontal movement of the load. It is a key component for transmitting lifting power and completing material hoisting operations. Its reliability directly affects the working safety and efficiency of the crane.

[0004] Currently, the most widely used method for monitoring crane wire ropes is electromagnetic detection. This method is based on detecting changes in the cross-sectional area of ​​the metal inside the wire rope, using the principle of electromagnetic induction to detect defects such as broken wires, wear, and corrosion. Existing monitoring devices use magnetization devices, specifically a circular magnetic yoke placed on the outside of the wire rope to ensure it is uniformly magnetized to saturation for subsequent monitoring. However, during operation, because the wire rope is wound on a drum, it moves back and forth during winding and unwinding. Existing circular magnetic yokes cannot move with the wire rope, potentially leading to incomplete magnetization, monitoring blind spots, and wear on both the wire rope and the yoke.

[0005] Therefore, it is necessary to provide a real-time wear monitoring and early warning device for crane wire ropes to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a real-time wear monitoring and early warning device for crane wire ropes, which solves the problem that in some existing crane wire rope monitoring devices, the circular magnetic yoke cannot move with the wire rope, resulting in potential monitoring blind spots due to unsaturated magnetization, and wear on the wire rope and magnetic yoke.

[0007] To solve the above-mentioned technical problems, this utility model provides a real-time wear monitoring and early warning device for crane wire rope, comprising: a mounting plate, wherein a monitoring component is provided at the bottom of the mounting plate; The monitoring component includes two sliding frames mirror-imagely positioned at the bottom of the mounting plate. Each sliding frame has a sliding groove on its inner side, and a roller is provided on the inner side of each sliding groove, which can slide back and forth along its length. A guide support frame is provided on the opposite side of the two rollers, and guide wheels are provided at the top and bottom of the guide support frame.

[0008] Preferably, an excitation coil module is provided on the right side of the inner wall of the guide support frame.

[0009] Preferably, the bottom of the guide support frame is provided with an annular support block, and three magnetic sensors are arranged in an array on the inner side of the annular support block. The ends of the three magnetic sensors away from the annular support block are all provided with wires.

[0010] Preferably, a data processing module is fixedly installed on the inner side of the guide support frame, and the ends of the three wires away from the corresponding magnetic sensors are all connected to the data processing module.

[0011] Preferably, a controller is provided on the left side of the sliding frame on the left side, and a warning light is provided on the inner side of the controller.

[0012] Preferably, the inner side of the mounting plate is provided with a through groove for the passage of a steel wire rope.

[0013] Compared with related technologies, the crane wire rope real-time wear monitoring and early warning device provided by this utility model has the following beneficial effects: This utility model provides a real-time wear monitoring and early warning device for crane wire ropes. By passing the wire rope through the inner side of two guide wheels, the two guide wheels will synchronously drive the guide support frame to move back and forth during the process of the wire rope being wound up. This ensures that the excitation coil module is always located on the outer side of the wire rope and will not contact its surface, thereby avoiding the problems of unsaturated magnetization and wear.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Please refer to the following: Figure 1 , Figure 2 , Figure 3 A real-time wear monitoring and early warning device for crane wire rope includes: a mounting plate 1, and a monitoring component 2 is provided at the bottom of the mounting plate 1; The monitoring component 2 includes two sliding frames 21 that are mirror images of each other on the bottom of the mounting plate 1. Each sliding frame 21 has a sliding groove 22 on its inner side. Each sliding groove 22 has a roller 23 that can slide back and forth along its length on its inner side. A guide support frame 24 is provided on the opposite side of the two rollers 23. Guide wheels 25 are provided on the top and bottom of the guide support frame 24.

[0017] By setting up a sliding frame 21, a sliding groove 22, and rollers 23, the guide support frame 24 can smoothly slide back and forth on the bottom of the mounting plate 1. The guide wheels 25 are in pairs, providing a guiding effect for the wire rope. When the wire rope moves longitudinally back and forth, it will force the guide wheels 25 to drive the guide support frame 24 to slide inside the two sliding grooves 22, thereby ensuring that the monitoring structure moves with it and avoiding problems such as wear and magnetization insufficiency.

[0018] An excitation coil module 26 is installed on the right side of the inner wall of the guide support frame 24.

[0019] Using the excitation coil module 26, the wire rope can be magnetized to ensure that it is uniformly magnetized to saturation. It can be set to a loop type or a C type.

[0020] The bottom of the guide support frame 24 is provided with an annular support block 27, and three magnetic sensors 28 are arranged in an array on the inner side of the annular support block 27. The ends of the three magnetic sensors 28 away from the annular support block 27 are all provided with wires 29.

[0021] Three magnetic sensors 28 are installed on the inner side of the annular support block 27 to avoid missing local damage, such as a broken wire on only one side.

[0022] A data processing module 3 is fixedly installed on the inner side of the guide support frame 24, and the ends of the three wires 29 away from the corresponding magnetic sensors 28 are all connected to the data processing module 3.

[0023] The data processing module 3 amplifies and filters the signal from the magnetic sensor 28, then converts it into a digital signal via an ADC. Combined with an inherent algorithm, the damage type is identified, such as broken wire, wear, or deformation.

[0024] A controller 4 is located on the left side of the left sliding frame 21, and a warning light 5 is located on the inside of the controller 4.

[0025] When the data processing module 3 detects damage to the wire rope, it outputs the data to the controller 4. The controller 4 then activates the warning light 5 to alert the operator to replace and repair the rope.

[0026] The inner side of the mounting plate 1 is provided with a through groove for the passage of a steel wire rope.

[0027] The main components of the crane are located on the top of the mounting plate 1, and the wire rope pulls the heavy object through the through groove.

[0028] The working principle of the real-time wear monitoring and early warning device for crane wire rope provided by this utility model is as follows: Step 1: When in use, the wire rope is passed through the inner side of the upper and lower guide wheels 25. As the wire rope is wound up and moves back and forth, the two guide wheels 25 will synchronously drive the guide support frame 24 to move back and forth, so that the excitation coil module 26 is always located on the outside of the wire rope and will not contact its surface, thereby avoiding the problems of unsaturated magnetization and wear. Step 2: When the wire rope passes through the excitation coil module 26, the excitation coil module 26 magnetizes the wire rope to ensure that it is uniformly magnetized to a saturation state. When the wire rope passes through the annular support block 27, three magnetic sensors 28 monitor the magnetic field inside the wire rope. The data processing module 3 amplifies and filters the signal from the magnetic sensors 28, and then converts it into a digital signal through the ADC. Combined with the inherent algorithm, the damage type is identified, such as wire breakage, wear, deformation, etc. Step 3: When the data processing module 3 detects damage to the wire rope, it outputs the data to the controller 4. The controller 4 then controls the warning light 5 to illuminate, reminding personnel to replace and repair it.

[0029] Compared with related technologies, the crane wire rope real-time wear monitoring and early warning device provided by this utility model has the following beneficial effects: By passing the wire rope through the inner side of the upper and lower guide wheels 25, the two guide wheels 25 will synchronously drive the guide support frame 24 to move back and forth during the process of the wire rope being wound up. This ensures that the excitation coil module 26 is always located on the outside of the wire rope and will not contact its surface, thereby avoiding the problems of magnetization insaturation and wear.
