Description

Technical Field

[0002] A lifting device is a mechanical device whose main function is to move objects up and down in the vertical direction. Lifting devices are widely used in various scenarios, including but not limited to industry, agriculture, construction, logistics and other fields.

[0003] Existing lifting devices also have significant shortcomings in the context of petrochemical oil storage tank areas. When it is necessary to hoist portable gas detectors to specific locations such as inside oil storage tanks for detection, traditional lifting devices lack intelligent control functions. Most of them can only be operated manually locally, and cannot achieve convenient remote control. In oil storage tank areas, operators often need to operate from safe areas far away from the tanks, and local manual control severely limits the flexibility and efficiency of operation. Moreover, traditional lifting devices do not have signal relay functions, which cannot improve the harsh communication environment of oil storage tank areas and cannot meet the needs of modern petrochemical industries for efficient and intelligent safety monitoring systems. Therefore, developing an automatic lifting device that integrates convenient control, precise lifting, and signal relay functions is of extremely important practical significance for improving the safety monitoring level of petrochemical oil storage tank areas.

[0023] 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.

[0024] like Figures 1 to 3 As shown, an automatic lifting monitoring device is disclosed, comprising a housing 1. A reduction drive assembly is fixedly installed inside the housing 1. A main shaft 9 is fixedly connected to the movable end of the reduction drive assembly. The reduction drive assembly includes a sealing shell 7, which is sealed and fitted onto the outer surface of the main shaft 9 and fixedly installed at the inner bottom of the housing 1. A motor 8 is fixedly connected to one side of the outer surface of the sealing shell 7. A worm gear 16 is fixedly connected to the drive end of the motor 8, and the worm gear 16 passes through the sealing shell 7 and is rotatably connected to it. A worm wheel 17 is meshed with the outer surface of the worm gear 16. The worm wheel 17 and the worm gear 16 have a large reduction ratio and can output a large torque to meet the power requirements of lifting equipment. The worm wheel 17 is fixedly fitted onto the outer surface of the main shaft 9. An encoder 10 is fixedly installed at one end of the main shaft 9 at the inner bottom of the housing 1, and the input shaft of the encoder 10 is fixedly connected to the main shaft 9. The encoder 10 can accurately measure the rotation angle and number of turns of the winch 2.

[0025] The main shaft 9 penetrates the housing 1 and is fixedly connected to the winch 2. The winch 2 is made of high-strength cast steel, possessing excellent structural strength and capable of withstanding large torque and tension, ensuring stable operation during hoisting operations. A bearing seat 6 extends through the housing 1 to one side of its outer surface, and the bearing seat 6 is fixedly connected to the housing 1. The inner ring of the bearing inside the bearing seat 6 is fixedly fitted onto the outer surface of the main shaft 9. An antistatic fiber belt 3 is wound around the outer surface of the winch 2, and a triangular lifting ring 5 is movably installed at the end of the antistatic fiber belt 3. The antistatic fiber belt 3 is woven from special antistatic fibers, possessing excellent flexibility for smooth winding and unwinding on the winch 2, and effectively preventing the accumulation and release of static charge, thus reducing the risk of safety accidents caused by static electricity at the source. The surface of the antistatic fiber belt 3 is treated with an anti-slip coating to increase friction at the connection point with the triangular lifting ring 5, preventing slippage during hoisting and ensuring the safe lifting and lowering of the hoisting equipment.

[0026] Two limiting rollers 4 are rotatably connected to one side of the outer surface of the housing 1, and the antistatic fiber belt 3 is positioned between the two limiting rollers 4.

[0027] A battery 15 is fixedly mounted on the inner wall of one side of the housing 1. The battery 15 is electrically connected to the power control module 14. The battery 15 is a 12V / 20Ah ternary lithium battery, which has high energy density, good charge and discharge performance, and relatively light weight, providing stable and long-lasting power support for the device. The power control module 14 integrates a sophisticated charging management circuit, which can achieve constant current and constant voltage charging in both 220V AC mains charging and solar charging modes. During AC mains charging, the charging management circuit ensures that the current and voltage output by the adapter accurately match the battery's charging needs; while during solar charging, it can dynamically adjust the charging parameters according to changes in the output power of the solar panel.

[0028] A microcontroller 11, a communication module 12, a drive module 13, and a power control module 14 are fixedly installed on one inner wall of the housing 1. The microcontroller 11 is electrically connected to the communication module 12, the drive module 13, the power control module 14, the encoder 10, and the motor 8.

[0029] The microcontroller 11 utilizes the high-performance STM32 series, which boasts abundant peripheral resources and powerful data processing capabilities. It integrates a dedicated hardware accelerator for communication protocol processing, enabling rapid parsing and execution of various control instructions. The chip features multiple general-purpose input / output (GPIO) pins for stable data interaction with a mobile app; another set of GPIO pins connects to an RS485 interface chip, providing a reliable communication channel for local control devices. To ensure stable operation of the control module in complex electromagnetic environments, a power supply filtering circuit is also included. This circuit employs a π-type filter structure composed of multilayer ceramic capacitors and inductors to effectively filter out noise interference from the power supply.

[0030] The drive module 13 employs an H-bridge drive circuit based on MOSFETs, which allows for flexible control of the forward and reverse rotation and speed of the motor 8. The MOSFET's on and off times are adjusted via a PWM signal, thereby precisely controlling the motor 8's speed. To prevent damage to the circuit from the back electromotive force generated during motor 8's start-up and stop, a freewheeling diode is connected in parallel across the motor 8 to absorb the back electromotive force.

[0031] The communication module 12 integrates a LoRa wireless communication module, a 4G remote communication module, and a GPS positioning module. The LoRa wireless communication module uses the LLCC68 chip as its core, offering excellent high sensitivity and low power consumption. The module has a built-in power amplifier, effectively enhancing signal transmission strength and ensuring long-distance communication in the complex environment of the oil tank area. A high-gain, anti-interference antenna is used. The LoRa self-organizing network function allows the device to build a communication network with numerous LoRa devices in the area, enabling data interaction and sharing between devices, effectively expanding signal coverage and improving data transmission efficiency. The 4G communication module supports mainstream 4G communication frequency bands, enabling fast and stable access to mobile networks. This module is equipped with an independent power management circuit, which dynamically adjusts power consumption according to communication load, extending the overall battery life of the device. Through 4G communication, the device can overcome the local limitations of the LoRa self-organizing network and conduct real-time data transmission with a remote monitoring center or cloud server. The GPS positioning module can obtain the device's geographical location information in real time.

[0032] The communication module 12 is also equipped with an intelligent communication protocol processing unit, which can automatically adapt to and parse various communication protocols according to different communication scenarios and device types, such as custom protocols, standard Modbus protocols and MQTT protocols, to facilitate seamless connection and data interaction with various devices.

[0033] Drivetrain System:

[0034] When the microcontroller 11 sends a start command to the motor 8 through the drive module 13, the output shaft of the motor 8 drives the worm gear 16 to rotate. The worm gear 16 and the worm wheel 17 form a worm gear 16 mechanism, which converts the high-speed rotation of the motor 8 into a low-speed, high-torque output of the worm wheel 17. Since the worm wheel 17 is fixedly sleeved on the main shaft 9, the main shaft 9 rotates accordingly and drives the winch 2 to wind or release the antistatic fiber belt 3.

[0035] The worm gear 17 and worm 16 mechanism have a self-locking characteristic, which can prevent the main shaft 9 from rotating in the opposite direction due to load when power is off, ensuring the safety of the lifting process. The sealing shell 7 seals and protects the transmission components to prevent dust from entering and affecting the transmission accuracy. The main shaft 9 is supported in both directions by the bearing seat 6 to ensure rotational stability.

[0036] Exercise monitoring feedback:

[0037] The encoder 10 is fixed coaxially with the main shaft 9, and detects the rotation angle and speed of the main shaft 9 in real time, feeding the data back to the microcontroller 11. The microcontroller 11 analyzes the pulse signal of the encoder 10 to accurately calculate the lifting height and speed of the antistatic fiber belt 3.

[0038] Two limit rollers 4 provide physical guidance for the antistatic fiber belt 3 to prevent it from running off-track; the triangular lifting ring 5 is the load connection point at the end of the antistatic fiber belt 3 and is used to connect the equipment.

[0039] Intelligent control and communication:

[0040] The microcontroller 11 serves as the core processing unit, integrating encoder 10 data, preset programs, and remote commands (received via communication module 12) to dynamically adjust the operating parameters of the motor 8.

[0041] The communication module 12 integrates LoRa (short-range low-power communication), 4G (remote data transmission), and GPS (location tracking) modules, supporting multi-mode communication: LoRa is used for local area network device networking, 4G enables cloud monitoring, and GPS provides device location information, forming a complete Internet of Things monitoring system.

[0042] Energy Management System:

[0043] The power control module 14 manages the charging and discharging process of the battery 15 and distributes power to components such as the motor 8 and the microcontroller 11. When insufficient power is detected, a low power alarm can be triggered and the status can be uploaded through the communication module 12.

[0044] The antistatic fiber belt 3 eliminates static electricity accumulation during the lifting process through its material properties, thus avoiding interference with the operation of electronic components.
