Description

Technical Field

[0001] This utility model relates to the field of mine safety monitoring technology, and in particular to a safety monitoring device for mine hoisting wire ropes. Background Technology

[0002] In mines, hoists are used to lift materials. Typically, a motor drives a single-rope winding or multi-rope friction drum. The object being lifted moves up and down by winding steel wire ropes onto the drum. When multiple steel wire ropes are used for lifting, uneven force during lifting can lead to tension imbalances in the individual steel wire ropes. This can cause the less tensile wire ropes to vibrate significantly during operation, resulting in displacement or collisions and posing safety hazards. Therefore, regular manual inspections are necessary.

[0003] Since manual inspection is not only inefficient, but also cannot monitor the wire rope in real time, it cannot completely eliminate safety hazards. Therefore, a safety monitoring device for mine hoisting wire ropes is proposed. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a safety monitoring device for mine hoisting wire ropes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a safety monitoring device for mine hoisting wire rope, comprising a wire rope and a mounting plate, wherein a microcontroller is fixedly mounted on one side of the mounting plate, a pressure sensor is fixedly mounted on the other side of the mounting plate, and a monitoring alarm structure is fixedly mounted below the microcontroller.

[0007] The monitoring and alarm structure includes a mounting box for installation. An alarm is fixedly mounted on the front of the mounting box. A support column is fixedly mounted on the inner wall of the back of the mounting box. A guide plate is movably mounted on the support column. A data storage module is fixedly mounted on the inner wall of the bottom of the mounting box. A motor is fixedly mounted on the inner wall of the back of the mounting box. A threaded rod is fixedly mounted on the output end of the motor. A sleeve is movably mounted on the threaded rod.

[0009] A connecting post is fixedly provided on the inner wall of the front side of the mounting box, and a conductive block is fixedly provided on the side of the connecting post that is close to the guide plate.

[0010] As a further description of the above technical solution:

[0011] A spring is fixedly installed on the inner wall of the back of the mounting box, and the other end of the spring is attached to the guide plate.

[0018] This utility model has the following beneficial effects:

[0019] 1. Compared with existing technologies, this mine hoisting wire rope safety monitoring device, through the installation of an alarm, a microcontroller, a motor, a pressure sensor, and a data storage module, enables real-time monitoring of the wire rope. When the wire rope vibrates, it strikes the pressure sensor on one side, which transmits the pressure value to the microcontroller. The microcontroller then compares the real-time data with a preset alarm value. When the pressure value exceeds the preset value, the microcontroller starts the motor, which drives the threaded rod to rotate clockwise. The threaded rod then drives the sleeve, which extends outward to compress the guide plate. The guide plate then drives the conductive block on one side. When the conductive block on the guide plate contacts the conductive block on the connecting column, the alarm is activated, alerting relevant personnel to a wire rope malfunction. This enables real-time monitoring of the wire rope and allows the device to locate and repair areas of significant wire rope vibration based on the pressure data in the data storage module.

[0020] 2. Compared with existing technologies, the safety monitoring device for mine hoisting wire ropes improves the heat dissipation rate by setting aluminum strips and heat dissipation fins. The aluminum strips absorb the heat inside the mounting box and dissipate it through multiple heat dissipation fins. Attached Figure Description

[0029] To enhance real-time security, a monitoring and alarm structure 5 is fixedly installed below the microcontroller 3. The monitoring and alarm structure 5 includes a mounting box 501 for installation. An alarm 502 is fixedly installed on the front of the mounting box 501. A support column 503 is fixedly installed on the inner wall of the back of the mounting box 501. A guide plate 504 is movably mounted on the support column 503. A spring 506 is fixedly installed on the inner wall of the back of the mounting box 501, with the other end of the spring 506 fitting against the guide plate 504. The bottom inner wall of the mounting box 501... A data storage module 507 is fixedly installed.

A sleeve 511 is movably sleeved on the threaded rod 510. The inner wall of the sleeve 511 is threaded. The threads of the threaded rod 510 and the inner wall of the sleeve 511 are compatible. The motor 509's front... Two limiting rods 512 are fixedly installed on the surface, and two limiting plates 513 are fixedly installed on the outside of the sleeve 511. The limiting plates 513 and the limiting rods 512 are movably connected. The pressure sensor 4 transmits the received pressure to the microcontroller 3 and the data storage module 507. The data in the data storage module 507 allows relevant personnel to more intuitively see the range of high pressure values, making it easier for them to find the range where the wire rope vibrates significantly. The microcontroller 3 compares the real-time data with the preset alarm value. When the pressure value... When the preset value is exceeded, the microcontroller 3 starts the motor 509, which drives the threaded rod 510 to rotate clockwise. The threaded rod 510 then drives the sleeve 511, which extends outward to press the guide plate 504. The guide plate 504 then drives the conductive block 505 on one side. When the conductive block 505 on the guide plate 504 contacts the conductive block 505 on the connecting post 508, the alarm 502 is powered on to alert relevant personnel that the wire rope has malfunctioned, thereby realizing real-time monitoring of the wire rope and improving safety.

[0030] To improve heat dissipation, several aluminum strips 514 are fixedly installed on the top inner wall of the mounting box 501. Heat dissipation fins 515 are fixedly installed on the top of the aluminum strips 514. The heat dissipation fins 515 are made of aluminum. The aluminum strips 514 absorb the heat inside the mounting box 501 and dissipate it through the multiple heat dissipation fins 515, which can improve the heat dissipation speed inside the mounting box 501.

[0031] Working principle: The conductive block 505 on the guide plate 504 is connected to the positive terminal of the battery via a wire. The conductive block 505 on the connecting post 508 is connected to the positive terminal of the alarm 502 via a wire. The negative terminal of the alarm 502 is connected to the negative terminal of the battery via a wire. Before use, the alarm pressure value is input into the microcontroller 3. When the wire rope vibrates, it will strike the pressure sensor 4 on one side. The pressure sensor 4 transmits the pressure value to the microcontroller 3 and the data storage module 507. The data in the data storage module 507 allows relevant personnel to more intuitively see the range of high pressure values, making it easier for them to find the area where the wire rope vibrates excessively. Within the specified range, the microcontroller 3 compares the real-time data with the preset alarm value. When the pressure value exceeds the preset value, the microcontroller 3 starts the motor 509. The motor 509 drives the threaded rod 510 to rotate clockwise. The threaded rod 510 then drives the sleeve 511. The sleeve 511 extends outward to compress the guide plate 504. The guide plate 504 then drives the conductive block 505 on one side. When the conductive block 505 on the guide plate 504 contacts the conductive block 505 on the connecting column 508, the alarm 502 is powered on to alert relevant personnel that the wire rope has malfunctioned. Multiple aluminum strips 514 and heat dissipation fins 515 can improve the heat dissipation speed of the mounting box 501.
