Description

Technical Field

[0001] This utility model relates to the field of mechanical safety monitoring technology, and in particular to a wire rope loosening and slippage early warning device. Background Technology

[0002] Steel wire ropes, as high-strength transmission and load-bearing components, are widely used in various heavy equipment and public facilities. However, during long-term operation, factors such as vibration and impact, load fluctuations, installation deviations, wear and aging, and environmental corrosion can cause abnormal conditions such as loosening and slippage at the ends of the steel wire ropes. If these abnormalities are not detected in time, they can lead to anything from reduced equipment operating accuracy and downtime for maintenance to serious safety accidents such as wire rope breakage, falling objects, and cableway shutdown, resulting in huge economic losses and casualties.

[0003] Currently, the industry's monitoring methods for wire ropes have significant limitations: First, manual inspection relies on the experience of staff, resulting in long monitoring cycles, high missed detection rates, and the inability to monitor in real time. This is especially true in harsh environments such as high altitudes, underground mines, and at night, where monitoring efficiency and accuracy are significantly reduced. Second, traditional sensor monitoring solutions mostly focus on wire rope wear, fatigue, or broken wires, lacking targeted monitoring of end loosening and slippage. Furthermore, some devices have complex structures, are difficult to install, and require destructive modifications to the wire rope, resulting in poor adaptability. Third, existing displacement monitoring components mostly use contact rollers or non-contact infrared sensors. The former is prone to false triggering due to wear on the wire rope surface, while the latter is greatly affected by environmental factors such as dust and oil, making it difficult to guarantee monitoring accuracy. Therefore, in view of the above situation, there is an urgent need to develop a wire rope loosening and slippage early warning device that can capture the loosening and slippage status of the wire rope end in real time, quickly trigger an early warning mechanism, provide real-time protection for the safe operation of equipment, effectively reduce the risk of safety accidents caused by wire rope end failure, and ensure the safety of personnel and property in industrial production and people's livelihood scenarios, so as to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a wire rope loosening and slippage early warning device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wire rope slippage warning device includes a metal induction probe, an arc-shaped claw, fastening bolts, a housing, an anti-slip pad, a displacement signal generator, a signal processing component, a warning component, and a wire rope. The arc-shaped claw is inserted into the housing. An arc-shaped groove is provided at the upper end of the housing, and an anti-slip pad is fixed in the arc-shaped groove. The wire rope passes through the space between the arc-shaped claw and the anti-slip pad. The inner wall of the arc-shaped claw has serrated protrusions adapted to the spiral pattern on the surface of the wire rope. The displacement signal generator is installed inside the housing. The metal induction probe is elastically connected to the displacement signal generator through a return spring. The metal induction probe passes through the housing and the anti-slip pad and contacts the wire rope. The bottom end of the arc-shaped claw is connected to two fastening bolts, and adjusting nuts are installed on the fastening bolts. The signal processing component and the warning component are installed inside the housing. The displacement signal generator and the warning component are electrically connected to the signal processing component through wires.

[0007] Preferably, a dustproof sealing ring is installed at the junction of the metal sensing probe and the outer shell.

[0008] Preferably, the signal processing component includes: a signal amplifier, a filtering module, a microprocessor, and a threshold setting unit.

[0009] Preferably, the early warning component includes: a fault indicator light, an audible and visual alarm, and an external signal interface.

[0010] Preferably, a power module is installed inside the housing.

[0011] The beneficial effects of this utility model are as follows: In use, the wire rope loosening and slippage early warning device involves passing the wire rope between the arc-shaped claw and the anti-slip pad. The arc-shaped claw is then adjusted using the fastening bolt and adjusting nut to clamp the wire rope. A metal induction probe detects the wire rope. When the wire rope becomes loose or slips, it causes the metal induction probe to move synchronously, thereby pushing the metal induction probe to compress the reset spring and transmitting the signal to the displacement signal generator. This triggers the displacement signal generator to generate an electrical signal, which is then sent to the signal processing component. The signal processing component amplifies the weak electrical signal output from the displacement sensing component. The signal is amplified to a recognizable range, and the filtering module filters out noise signals generated by environmental electromagnetic interference. The microprocessor analyzes the processed signal in real time and compares it with the preset displacement threshold in the threshold setting unit to determine whether the wire rope is in an abnormal state. When the signal processing component determines that the wire rope is loose or slipping, it immediately controls the audible and visual alarm to sound a buzzer and flash a red light, while simultaneously illuminating the fault indicator. The external signal interface can transmit the warning signal to the equipment's main control system or remote monitoring platform, triggering the equipment's emergency shutdown procedure or pushing alarm information to the management personnel's terminal, thereby achieving multiple alarms. In summary, this utility model can capture the loosening and slipping status of the wire rope end in real time, quickly triggering an early warning mechanism, providing real-time protection for the safe operation of equipment, effectively reducing the risk of safety accidents caused by wire rope end failure, and ensuring the safety of personnel and property in industrial production and civilian scenarios.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Specific implementation examples are given below.

[0019] See Figures 1-3 In this embodiment of the present invention, a wire rope loosening and slippage early warning device includes a metal induction probe 1, an arc-shaped claw body 2, a fastening bolt 3, a housing 4, an anti-slip pad 6, a displacement signal generator 7, a signal processing component 9, an early warning component, and a wire rope 11. The arc-shaped claw body 2 is inserted into the housing 4. The upper end of the housing 4 is provided with an arc-shaped groove, and the anti-slip pad 6 is fixed in the arc-shaped groove. The wire rope 11 passes through the space between the arc-shaped claw body 2 and the anti-slip pad 6. The anti-slip pad 6 increases the friction with the wire rope 11 while avoiding damage to the surface of the wire rope 11. The inner wall of the arc-shaped claw body 2 is equipped with serrated protrusions 201 that match the spiral pattern on the surface of the wire rope 11, ensuring that the arc-shaped claw body 2 and the wire rope 11 are in close contact. The displacement signal generator 7, signal processing component 9, and early warning component 11 are provided. The generator 7 is installed inside the housing 4. The metal sensing probe 1 is elastically connected to the displacement signal generator 7 through a return spring. The metal sensing probe 1 passes through the housing 4 and the anti-slip pad 6 and contacts the wire rope 11. The metal sensing probe 1 detects the wire rope 11. The bottom end of the arc-shaped claw 2 is connected to two fastening bolts 3. An adjusting nut 301 is installed on the fastening bolts 3. The tightness of the arc-shaped claw 2 is adjusted by the fastening bolts 3 and the adjusting nut 301, so as to adapt to different specifications of wire rope 11 with diameters of 12-80mm without the need for additional processing of the wire rope 11. The housing 4 is equipped with a signal processing component 9 and an early warning component. The displacement signal generator 7 and the early warning component are electrically connected to the signal processing component 9 through wires.

[0020] A dustproof sealing ring is installed at the junction of the metal sensing probe 1 and the outer shell 4 to prevent external dust and oil from entering the interior of the outer shell 4. The detection module consists of the metal sensing probe 1, the displacement signal generator 7, and the reset spring. When the wire rope 11 becomes loose or slips, it will drive the metal sensing probe 1 to move synchronously, thereby pushing the metal sensing probe 1 to compress the reset spring and transmit it to the displacement signal generator 7, triggering the displacement signal generator 7 to generate an electrical signal.

[0021] The signal processing component 9 includes a signal amplifier, a filtering module, a microprocessor, and a threshold setting unit. The signal amplifier amplifies the weak electrical signal output by the displacement sensing component to a recognizable range. The filtering module filters out noise signals generated by environmental electromagnetic interference. The microprocessor performs real-time analysis on the processed signal and compares it with the preset displacement threshold (set to 0.3-2mm according to the equipment operating conditions) in the threshold setting unit to determine whether the wire rope 11 is in an abnormal state.

[0022] The early warning component includes: a fault indicator light 5, an audible and visual alarm 8, and an external signal interface. When the signal processing component 9 determines that the wire rope 11 has become loose or slipped, it immediately controls the audible and visual alarm 8 to emit a buzzer alarm of more than 100dB and a red flashing light, while simultaneously illuminating the fault indicator light 5. The external signal interface supports the RS485 / CAN bus protocol, which can transmit the early warning signal to the equipment main control system or remote monitoring platform, triggering the equipment emergency shutdown procedure or pushing alarm information to the management personnel terminal.

[0023] A power module 10 is installed inside the outer casing 4, and the power module 10 supplies power to the aforementioned electrical components.

[0024] Working Principle: In use, the wire rope 11 is passed between the arc-shaped claw 2 and the anti-slip pad 6. The arc-shaped claw 2 is adjusted using the fastening bolt 3 and adjusting nut 301 to clamp the wire rope 11. The wire rope 11 is detected by the metal induction probe 1. When the wire rope 11 becomes loose or slips, it causes the metal induction probe 1 to move synchronously, thereby pushing the metal induction probe 1 to compress the reset spring and transmitting the signal to the displacement signal generator 7. This triggers the displacement signal generator 7 to generate an electrical signal, which is then sent to the signal processing component 9. The signal processing component 9 amplifies the weak electrical signal output by the displacement sensing component to a detectable range through a signal amplifier. The filtering module filters out noise signals generated by environmental electromagnetic interference. The microprocessor processes the signal... The system performs real-time analysis and compares the displacement threshold with the preset threshold in the threshold setting unit to determine whether the wire rope 11 is in an abnormal state. When the signal processing component 9 determines that the wire rope 11 is loose or slipping, it immediately controls the audible and visual alarm 8 to sound a buzzer alarm and flash a red light, while simultaneously illuminating the fault indicator 5. The external signal interface can transmit the warning signal to the equipment main control system or remote monitoring platform. After receiving the signal, the equipment main control system cuts off the power supply within one second to achieve an emergency shutdown. The remote monitoring platform simultaneously receives the alarm information and pushes it to the management personnel. After the staff troubleshoots and handles the loosening and slipping of the wire rope, they manually press the metal induction probe 1 three times in succession. The metal induction probe 1 returns to its original position under the action of the reset spring, the device returns to the normal monitoring state, and the warning signal is released.

[0025] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
