Description

Technical Field

[0001] This invention relates to the field of lifting equipment, specifically to a wire rope testing device for gantry cranes. Background Technology

[0002] In the fields of industrial production and logistics transportation, gantry cranes, as an important lifting equipment, are widely used in ports, docks, railway freight yards, and other places, undertaking key tasks such as loading, unloading, and handling of goods. Like a crucial gear in a highly efficient logistics hub, its powerful lifting capacity and flexible operation ensure the smooth flow of goods between different transportation links, serving as a vital support for ensuring the stability of the logistics supply chain and the continuity of industrial production.

[0003] As a critical load-bearing component of gantry cranes, the performance of the wire rope directly affects the crane's operational safety and reliability. Under the complex and variable operating conditions of gantry cranes, the wire rope not only bears enormous axial tensile forces, which fluctuate significantly with the weight of the hoisted goods, placing extremely high demands on its strength and toughness, but it is also subjected to lateral forces generated by factors such as side wind loads and crane swaying. For example, during port operations, strong sea winds exert a continuous lateral thrust on the suspended wire rope; during crane startup, braking, or movement, the wire rope is also subjected to lateral tensile forces due to inertia. These lateral forces cause the wire rope to bend, twist, and deform. Prolonged exposure to this complex stress environment intensifies the friction between the internal wires, making it highly susceptible to wear, breakage, and other failures. The consequences of a wire rope failure are unimaginable. At best, it could cause goods to fall, resulting in equipment damage and cargo loss, affecting normal production operations; at worst, it could lead to major safety accidents such as crane overturning, threatening the lives of on-site workers and causing huge economic losses and adverse social impacts to enterprises and society.

[0004] To improve the service life and operational safety of wire ropes, testing equipment is needed to inspect their mechanical properties and surface wear. According to the inventor's research, conventional testing equipment includes the following:

[0005] 1) Announcement No. CN114624119B discloses a wire rope strength testing device for cranes. In this patent application, an operating table is included. Placement platforms are fixedly connected to the left and right sides of the upper surface of the operating table. A first clamping plate is provided above each of the two placement platforms. A first placement groove is opened at the center of the upper surface of each of the two placement platforms. Multiple first toothed grooves are opened on the upper surface of each of the two placement platforms. Multiple first locking teeth that match the first toothed grooves are fixedly connected to the lower surface of each of the two first clamping plates. The wire rope body is fixed by the toothed grooves and locking teeth between the clamping plates. At the same time, one end of the wire rope body is fixed twice, avoiding the trouble of the wire rope body easily loosening when the strength test is performed by the tension hydraulic cylinder. This makes the two ends of the wire rope body more stable and the strength test more accurate.

[0006] 2) Announcement No. CN114923619B discloses a multi-rope tension detection device and method for hoist wire ropes. In this patent application, the multi-rope tension detection device for hoist wire ropes includes: a support system, wherein the bracket can be fixed to the ground by a base and its height can be adjusted by a position adjustment hole; a testing system, wherein the striking device is fixed to the bracket via a crossbeam, and a suspended beam is connected by a swing arm, with several adjustable-spaced striking hammer connectors fixed on the suspended beam; and an electromagnetic control system, wherein the electromagnetic control component is rigidly connected to the crossbeam of the striking device and includes a synchronous shaft assembly and a one-way self-locking assembly. The electromagnetic control component also includes a one-way self-locking assembly. This multi-rope tension detection device and method for hoist wire ropes can simultaneously measure the tension of multiple wire ropes and provide adjustment suggestions, realizing the tension detection of wire ropes in mining hoists.

[0007] 3) Publication No. CN118746493A discloses a crane wire rope testing device. This patent application includes a frame, a testing mechanism, and two sets of fixing mechanisms. Each fixing mechanism includes a clamp head, a slide rail, a pull rope, and a winding assembly. The slide rail is mounted on the frame. The clamp head is slidably mounted on the slide rail. One end of the pull rope is fixed to the clamp head, and the other end is connected to the winding assembly. The clamp head includes a clamp body, a first clamping plate, and a clamping bolt. The clamp body has a clamping hole for placing the end of the wire rope. The first clamping plate is slidably mounted inside the clamp body and can enter the clamping hole. The clamping bolt is threaded onto the clamp body, with one end abutting against the first clamping plate and the other end outside the clamp body. This technical solution not only offers high operational convenience but also improves the fixing effect on the wire rope, facilitating the testing of the wire rope.

[0008] The aforementioned publicly disclosed testing / inspection equipment explores and innovates wire rope testing technologies from the perspectives of wire rope strength testing, multi-rope tension testing, and ease of wire rope fixing and testing operations. However, these technologies can only optimize a specific performance characteristic or a single testing requirement of the wire rope, neglecting the interrelationships and mutual influences among the various performance characteristics of the wire rope during actual use. Furthermore, under complex working conditions, wire ropes simultaneously face multiple performance changes and potential failure risks. For example, wire rope wear not only affects its strength but also alters its tension distribution; abnormal tension can further exacerbate wear and fatigue. Therefore, existing testing equipment struggles to comprehensively and holistically assess the true condition of the wire rope, failing to provide a comprehensive and accurate basis for its maintenance and management. Summary of the Invention

[0009] The purpose of this invention is to provide a gantry crane wire rope testing device that can simultaneously and comprehensively test the mechanical properties, surface wear condition, and comprehensive state of multi-directional stress under complex working conditions of the wire rope. By collecting multi-dimensional data, it provides richer and more accurate information for the performance evaluation of the wire rope, greatly improving the reliability and comprehensiveness of the test results.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a wire rope testing device for gantry cranes.

[0019] This invention overcomes the limitations of traditional testing equipment, which can only test a single performance or force in a single direction. It can simultaneously and comprehensively test the mechanical properties of wire ropes (such as strength and tension), surface wear, and the combined state of multi-directional forces (axial tension, lateral force generated by lateral wind load, force generated by crane oscillation, etc.) under complex working conditions. Through the collection of multi-dimensional data, it provides richer and more accurate information for the performance evaluation of wire ropes, greatly improving the reliability and comprehensiveness of the test results. Specific technical effects include the following:

[0020] 1. Through the coordinated action of dragging component A (X-axis) and dragging component B (Z-axis), lateral wind load simulation (lateral shear force) and lifting axial tension can be applied simultaneously, accurately reproducing the actual stress state of wire ropes in scenarios such as ports and railway freight yards.

[0021] 2. The wear detection module uses an electric slide to drive a vision sensor to scan along the axial direction of the wire rope. Combined with an image recognition algorithm, it can detect surface wear and wire breakage defects. Attached Figure Description

The steel cable clamp 215 moves with the dragging electric cylinder 214 and causes the wire rope to be stretched or displaced laterally in the horizontal transverse direction (X-axis) (simulating the swinging of the crane or the lateral wind load). The dragging component B is located in the longitudinal extension direction of the lifting adjustment component C.

The mounting bracket 303 slides along the length of the electric slide 302. The vision sensor 304 is provided on the mounting bracket 303.

[0039] In conjunction with the above embodiments, the present invention also provides a detection principle for a gantry crane wire rope detection device, including the following:

[0040] Multi-directional tension simulation and detection: The towing component A is located on the transverse symmetrical axis of lifting adjustment components A and B. Its wire rope clamp 215 moves with the towing electric cylinder 214, causing lateral tension or displacement of the wire rope in the horizontal transverse direction (X-axis), simulating the working conditions of the wire rope under sway or lateral wind load during the operation of the gantry crane. Simultaneously, the towing component B is located in the longitudinal extension direction of the lifting adjustment component C. Its wire rope clamp 215 moves with the towing electric cylinder 214, causing tensile or compressive displacement of the wire rope in the vertical longitudinal direction (Z-axis), simulating the axial load borne by the wire rope during lifting / lowering. When the wire rope is subjected to tension in different directions, tension sensors installed on the wire rope collect tension data in real time and transmit the data to the control console 102. The integrated data acquisition card of the console 102 receives these data at a high-speed, high-precision sampling frequency. The signal conditioning module filters and amplifies the original signal to improve the signal quality. The signal is then analyzed and processed by the high-performance industrial controller to obtain the tension-displacement curves of the wire rope under different working conditions and to evaluate the tensile strength, elastic modulus and other mechanical properties of the wire rope.

[0041] Precise control and detection of tension: Wire rope tensioning component A is the upper wire rope tensioning clamp 206, and wire rope tensioning component B includes a slide plate 210, a movable support 211, an adjusting screw 212, and a lower wire rope tensioning clamp 213. The lower wire rope tensioning clamp 213 is slidably connected to the slide plate 210, and the lower wire rope tensioning clamp 213 and the upper wire rope tensioning clamp 206 respectively clamp the upper and lower ends of the wire rope. By adjusting the adjusting screw 212 hinged to the lower rear end of the slide plate 210, the position of the lower wire rope tensioning clamp 213 can be precisely adjusted, thereby controlling the tension of the wire rope. During tensioning, a tension sensor monitors the tension of the wire rope in real time and feeds the data back to the control console 102. According to the preset tension value, the control console 102 adjusts the position of the first guide plate 203 and the second guide plate 209 by controlling the driving components on the lifting adjustment components A, B and C, thereby changing the position of the wire rope tensioning component and the dragging component, realizing precise control and dynamic adjustment of the tension force, and ensuring that the wire rope is always in the set tension state during the testing process.

[0042] Wear Detection: During the detection process, the electric cylinder 301 drives the electric slide 302 to reciprocate along the length of the wire rope. Simultaneously, the electric slide 302 drives the vision sensor 304 on the mounting bracket 303 to scan in a direction perpendicular to the wire rope. The vision sensor 304 acquires image information of the wire rope surface in real time using a high-resolution image acquisition method and transmits the image data to the control console 102. The data analysis and processing software integrated into the control console 102 analyzes and processes the wire rope surface images acquired by the vision sensor 304. First, the software preprocesses the images, including noise reduction and enhancement, to improve image quality and clarity. Then, an image segmentation algorithm is used to separate the wire rope surface from the background and extract the feature information of the wire rope surface. Next, by comparing and analyzing with pre-stored standard wire rope surface images, image recognition technology is used to detect defects such as wear, cracks, and broken wires on the wire rope surface. Based on parameters such as the size, shape, and quantity of defects, and in conjunction with preset wear assessment standards, the wear degree of the wire rope is quantitatively assessed, generating a detailed wear inspection report, providing a scientific basis for the maintenance and replacement of the wire rope.

[0043] Comprehensive Performance Evaluation: Control console 102 comprehensively analyzes and processes the data obtained from mechanical performance testing and wear testing. By comprehensively evaluating the mechanical performance indicators and wear levels of the wire rope under different working conditions, a comprehensive performance evaluation model for the wire rope is established. This model considers multiple factors such as the tensile strength, elastic modulus, and wear rate of the wire rope, and uses weighted scoring methods to quantitatively evaluate the comprehensive performance of the wire rope. Based on the evaluation results, the service life of the wire rope can be predicted, providing decision support for the safe operation of the gantry crane. For example, when the comprehensive performance evaluation score of the wire rope falls below a set threshold, control console 102 issues a warning signal, prompting operators to replace the wire rope in a timely manner to ensure the safe operation of the gantry crane.

Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Any changes, modifications, substitutions and variations made by those skilled in the art to the above embodiments within the scope of the present invention should be included within the protection scope of the present invention.
