Description

Technical Field

[0001] The utility model relates to the field of combined rope saw machines, in particular to a rope saw vibration detection device. Background Art

[0002] When processing large stone panels (height ≥1.5 meters, length ≥2 meters), the combination wire saw machine has the advantages of high efficiency, simple equipment operation, low production cost, high stone utilization rate, less environmental pollution, etc. compared with traditional sand saws and circular saws. The combination wire saw machine represents the development trend of stone large panel cutting and processing; and the diamond wire saw is an important component of the combination wire saw machine, which can cut large stone blocks into multiple large panels. If the wire saw vibrates too much during cutting, it will directly affect the cutting quality of the panel. In the past, a reference object was placed about 20mm below the wire saw. If the combination wire saw machine does not touch the reference object during the process of adjusting the online speed to the highest, it is considered that the wire saw vibrates in accordance with the requirements. This detection method has the problems of low and inaccurate detection accuracy, which is not conducive to equipment quality detection.

[0003] Prior art CN201610002992.0 discloses a device for detecting the vibration amplitude of a wire rope, including: a detection head, a tilt adjuster, an elevation adjuster, a bracket, a support leg, and a data collector; the detection head is installed on the tilt adjuster, the tilt adjuster is connected to the elevation adjuster, and the elevation adjuster is installed in the middle of the axis at the top of the bracket, the support leg is connected to the bottom of the bracket through a hinge, and the data collector is connected to the detection head through a data cable. Although the invention uses a measuring light curtain as a sensing element to achieve non-contact measurement of the vibration amplitude of the wire rope, the following problems still exist:

[0004] 1. The invention can only detect the jitter change at one angle, but has limited monitoring capability for the three-dimensional complex jitter pattern (including multi-directional vibrations such as lateral, longitudinal and torsional vibrations) generated by the wire saw of the combination wire saw machine during wire saw cutting, and may not be able to fully reflect the jitter condition under actual working conditions.

[0005] 2. Although a non-contact measurement method is used, the measuring light curtain of the device may not be sensitive enough when facing a high-speed moving rope saw, and because the rope saw has a small vibration amplitude, it is impossible to accurately capture the subtle vibration changes of the rope saw, affecting the accuracy of the detection results.

[0006] 3. In the operating environment of the combined wire saw machine, changes in light conditions (such as direct strong light, shadow blocking) and on-site dust, water mist, etc. may interfere with the normal operation of the light curtain, thereby affecting the reliability of the detection data. Utility Model Content

[0007] In view of this, the purpose of the utility model is to provide a rope saw jitter detection device, which makes the rope saw electrified by using a conductive device, and uses the cooperation of the detection device to make the rope saw contact with the detection scale when it jitters, thereby triggering a signal. The control system displays the scale position data and then analyzes the jitter state of the rope saw.

[0008] The technical solution adopted by the utility model to solve its technical problems is:

[0009] A rope saw vibration detection device is provided, comprising: a conductive device, a detection device and a control system, wherein the control system is electrically connected to the conductive device and the detection device, and the conductive device is in contact with the rope saw and can charge the rope saw;

[0010] The detection device includes a detection scale, a detection box and an adjustment bracket. The detection box is arranged on the adjustment bracket. A through hole is provided in the middle of the detection box for the rope saw to pass through. The detection scale is evenly arranged on the detection box outside the through hole around the rope saw, and the detection scale can move radially along the through hole.

[0011] It should be noted that the conductive device only needs to be able to energize the rope saw when the rope saw is running. A contact wheel or a contact pick or other equipment that does not affect the operation of the rope saw can be used. This solution contacts the rope saw through a conductive device (such as a contact wheel) to energize the rope saw. In the detection device, the detection scales are arranged around the rope saw on the outside of the through hole on the detection box, and these detection scales can move along the radial direction of the rope saw, that is, perpendicular to the direction of movement of the rope saw. The control system is connected to the conductive device and the detection device. When the rope saw contacts any detection scale due to jitter during high-speed movement, the circuit is closed, and the control system can receive the signal and record the event, and display the scale position data through the control system, and then analyze the jitter state of the rope saw, so as to determine whether the rope saw jitter meets the requirements, and monitor the jitter state of the rope saw at different linear speeds in real time, improve the accuracy and sensitivity of the detection, and make the monitoring of the rope saw jitter more direct and real-time, avoiding the inaccuracy of traditional detection relying on static reference objects, which helps to improve the cutting quality and equipment maintenance efficiency.

[0012] Preferably, the conductive device comprises a contact wheel and a support frame, wherein the contact wheel is arranged on the support frame and can contact the rope saw.

[0013] It should be noted that the contact wheel and support frame design enables the contact wheel to directly contact the rope saw and transmit electrical signals through physical contact, while the support frame is responsible for fixing the contact wheel to ensure that it maintains stable contact with the rope saw, thereby improving the reliability of contact and the continuity of detection, making the device easier to adjust and maintain, and improving the overall stability and practicality.

[0014] Preferably, the support frame comprises a support seat and an adjusting rod, the adjusting rod is arranged on the support seat, the contact wheel is arranged on the adjusting rod, and the position of the contact wheel can be adjusted by the adjusting rod.

[0015] It should be noted that the height of the contact wheel can be adjusted by adjusting the rod to perfectly fit the rope saws of different diameters or heights; the adaptability of the system is increased, and no matter how the rope saw changes, it can ensure continuous and effective contact between the conductive device and the rope saw.

[0016] Preferably, there are four detection scales, which are respectively arranged around the rope saw on the detection box outside the through hole.

[0017] It should be noted that the four detection scales are used to form full coverage of the circumference of the rope saw in four directions: up, down, left, and right. Any jitter in any direction can be captured by at least one scale, thereby improving the comprehensiveness and reliability of the detection.

[0018] Preferably, the detection box comprises a scale mounting seat and a protective cover, the scale mounting seat is fixed on the adjustment bracket, the protective cover is arranged on the outside of the scale mounting seat, and the detection scale is correspondingly arranged on the scale mounting seat.

[0019] It should be noted that the scale mounting base can make the installation and adjustment of the detection scale faster, the protective cover can protect the scale from external damage, facilitate the adjustment of the scale position, ensure that the scale and the rope saw maintain an appropriate distance, will not touch each other in a static state, and only trigger a signal when shaking.

[0020] Preferably, the detection ruler is a telescopic ruler, and can automatically adjust its length along the radial direction of the through hole under the control of a control system.

[0021] It should be noted that the use of a telescopic ruler can automatically adjust its length and respond to the instructions issued by the control system so that the ruler can automatically adapt to the changes in the diameter of the rope saw without manual adjustment. This not only simplifies the operating process, but also improves the level of automation of detection, ensuring that each measurement accurately matches the actual size of the rope saw and improves detection accuracy.

[0022] Preferably, the adjustment bracket comprises a base and a telescopic rod, one end of the telescopic rod is arranged on the base, and the other end is connected to the detection box, and the base can move freely under the rope saw.

[0023] It should be noted that the movable base enables the entire detection device to move freely under the rope saw to adapt to rope saw detection in different positions. By adjusting the telescopic rod, the detection box can be quickly adjusted to the optimal monitoring detection height of the rope saw, so that the rope saw passes through the center of the through hole, ensuring the accuracy of the detection and improving the flexibility and adaptability of the device. No matter where the rope saw is, the detection device can be quickly adjusted to the optimal detection position, enhancing practicality and reducing the complexity of equipment adjustment.

[0025] The utility model provides a rope saw vibration detection device, which makes the rope saw electrified through a conductive device and contacts the detection scale to trigger a signal when it vibrates, and the control system immediately displays the scale position data. Compared with the traditional detection method that relies on static reference objects, the detection accuracy and instant response capability are greatly improved, which is helpful to monitor the vibration state of the rope saw in real time and ensure the cutting quality; it supports multi-dimensional vibration monitoring, including vibration in multiple directions such as lateral, longitudinal and torsional directions, solves the limitation of the prior art that only a single angle can be detected, and comprehensively reflects the actual working state of the rope saw; at the same time, the design of the telescopic scale, the scale mounting seat and the adjustment rod enables the detection device to be flexibly adjusted to adapt to the detection of rope saws in different positions, increasing the wide range of applications; the non-contact electrical conduction detection avoids the problem that optical detection is disturbed by environmental factors such as light, dust, and water mist, and improves the stability and reliability of the detection. Moreover, through the optimized design of mechanical structures such as the support frame and the adjustment rod, the stable operation and long-term durability of the equipment under various working conditions are ensured.
