[0002] With the increasing demand for aerial work in industries such as electricity, communications, and construction, various types of lifting platforms are widely used in the field of aerial work. Existing lifting platforms are generally divided into two types: manual and automatic. Among them, automatic lifting platforms have significant advantages in improving work efficiency and ensuring the safety of operators. However, most of the lifting platforms in the prior art have the following shortcomings: First, the structure is relatively simple and cannot adapt to complex terrain and uneven ground, which leads to easy tilting or overturning on soft, slippery or steep ground, thereby affecting the stability and safety of the operation; second, most of the existing lifting platforms lack effective automatic leveling functions. When the ground is uneven, the platform is prone to tilt, which increases the safety risks of the operators, especially when working at high altitudes. The instability of the equipment caused by the tilt may cause accidents. Therefore, the existing technology cannot meet the needs of stable operation under various complex terrains, especially in the high-altitude working environment where the stability of the lifting platform is required to be high, and there is still a lot of room for improvement in safety and reliability.

[0038] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Please see attached Figure 1 - Attachment Figure 4 The embodiment of the present invention provides a self-propelled insulating lifting platform, comprising:

[0040] The chassis 9 is used as a support carrier of the entire device. Two special crawlers 1 are installed at the bottom of the chassis 9. The special crawlers 1 are used to provide excellent traction to ensure the stable walking of the entire platform on various complex ground surfaces;

[0041] Specifically, the length and width of the chassis 9 should be designed to ensure that the platform will not overturn when it is raised and carrying the maximum load. The height of the chassis 9 itself should be moderate, taking into account that there is enough space below to install the crawler tracks, but not too high to cause the center of gravity of the entire lifting platform to move upward, affecting stability.

[0042] A lifting assembly is installed on the top of the chassis 9 and is used to adjust the height of the platform. A top plate 7 is installed on the top of the lifting assembly, and fixing rods 6 are installed at the four corners of the top of the top plate 7;

[0043] An adjustment component is installed on the inner side of the fixed rod 6, and the adjustment component is used to adjust the height of the railing; a control box 2 is installed on one side of the chassis 9, and an integrated weather station component is installed on the top side of the chassis 9. The integrated weather station component is used to adjust the operating state of the lifting platform in real time according to the temperature, humidity and wind speed of the environment. A radiator 14 is provided on the outer surface of the control box 2.

[0044] The integrated weather station assembly includes a wind speed sensor 3 and a temperature and humidity sensor 22. Both the wind speed sensor 3 and the temperature and humidity sensor 22 are fixedly mounted on one side of the top of the control box 2. The wind speed sensor 3 is used to monitor and measure the wind speed in the environment in real time. Through changes in wind speed, the wind speed sensor 3 can output an electrical signal proportional to the wind speed to change the operating state of the device. The temperature and humidity sensor 22 is used to measure the relative humidity of the environment.

[0045] Specifically, when the wind speed in the environment changes, the wind speed sensor 3 senses the change in air velocity and converts the wind speed change into a corresponding electrical signal through the built-in sensor element. The electrical signal is proportional to the wind speed, and the intensity and frequency changes of the signal can reflect the real-time wind speed. When the wind speed exceeds the preset range, the control system will make corresponding adjustments based on the received signal.

[0046] The temperature and humidity sensor 22 measures the relative humidity of the environment by sensing the water vapor content in the surrounding air. Through the real-time feedback of the temperature and humidity sensor 22, the system can respond in time when the humidity and temperature reach the set threshold value to avoid the environment being too wet or too dry.

[0047] An electric winch 15 is installed at the bottom end of the chassis 9, and the electric winch 15 is used to assist in providing additional pulling force.

[0048] Specifically, when the platform needs additional pulling force to complete a specific task (e.g., climbing a slope, pulling a heavy object, overcoming an obstacle, etc.), the electric winch 15 is activated. The motor drives the winch body to rotate, thereby driving the retraction and release of the steel wire rope or synthetic fiber rope. The steel wire rope transmits the pulling force by connecting with the target object, assisting the platform to complete the required operation.

[0049] The lifting assembly includes a first hydraulic cylinder 11, which is fixedly mounted on the top of the chassis 9. The output end of the first hydraulic cylinder 11 is movably connected to a hinged rod 10, the top of the hinged rod 10 is movably connected to the bottom of the top plate 7, and the bottom of the hinged rod 10 is movably connected to the bottom of the chassis 9.

[0050] A support base 4 is fixedly connected to one side of the top end of the top plate 7, an operating platform 5 is fixedly connected to the top of the support base 4, and a forward and backward operating lever 17 and an acceleration and deceleration operating lever 18 are installed on the top of the operating platform 5 from left to right in sequence. The forward and backward operating lever 17 is used to control the forward and backward instructions of the platform, and the acceleration and deceleration operating lever 18 is used to control the speed of the platform.

[0051] Specifically, the top plate 7 serves as the upper supporting structure of the entire system, and a support base 4 is fixedly connected to one side of the top thereof. The function of the support base 4 is to provide stable support for the upper operating platform 5 to ensure that the operating platform 5 does not shift or shake during use. The support base 4 is made of engineering plastic to meet the supporting force required by the platform during operation. The operating platform 5 serves as an interface between the operator and the platform control system and is an important component for controlling the operating status of the platform. Through the operating platform 5, the operator can input various control instructions for the platform, thereby affecting the movement behavior of the platform. In the actual use of the platform, the operating platform 5 usually needs to have an ergonomically designed structure to facilitate the operator to perform convenient operations in various working environments.

[0052] The adjustment assembly includes an installation cavity 21, which is opened inside the fixed rod 6, and the movable rod 16 is slidably connected inside the installation cavity 21, wherein the rack plates 20 are fixedly connected inside the two movable rods 16, wherein the servo motors 8 are installed outside the two fixed rods 6, and the output end of the servo motor 8 is fixedly connected to the transmission shaft 19, and the outside of the transmission shaft 19 is fixedly connected to the gear 23. The outer side of the gear 23 is meshed and connected with the outer side of the rack plate 20, and the end of the transmission shaft 19 away from the servo motor 8 is rotatably connected to the inner wall of the fixed rod 6.

[0053] Specifically, the servo motor 8 drives the transmission shaft 19 to rotate, and the rotation of the transmission shaft 19 drives the gear 23 to rotate, and the gear 23 meshes with the rack plate 20, and finally the movable rod 16 slides along the installation cavity 21. The sliding direction of the movable rod 16 is consistent with the tooth shape direction of the rack plate 20, so as to achieve the height adjustment of the railing or platform. Due to the high-precision control of the servo motor 8, the entire adjustment process can achieve fast and accurate positioning, and meet the height adjustment requirements in different working environments. The adjustment component has a simple and compact structure and occupies a small space.

[0054] The second hydraulic cylinder 12 is fixedly connected to the periphery of the exterior of the chassis 9 , and the output end of the second hydraulic cylinder 12 is fixedly connected to a support plate 13 .

[0055] Specifically, the second hydraulic cylinder 12 is activated to drive the support plate 13 to move downward so that the support plate 13 can contact the ground, thereby adjusting the tilt angle of the lifting platform.

[0056] Please see attached Figure 5 - Attachment Figure 7 , a control system for a self-propelled insulating lifting platform, comprising:

[0057] The main control module is responsible for overall system control and coordination, and manages the workflow of all subsystems;

[0058] Automatic leveling module, which automatically adjusts the horizontal state of the platform according to the platform inclination to ensure that the platform remains stable;

[0059] Specifically, the control unit processes the data from the tilt sensor and decides whether the height of the legs needs to be adjusted to achieve automatic leveling of the platform.

[0060] The hydraulic outrigger control unit adjusts the height and position of the outriggers according to the instructions of the control unit, so that the platform can be automatically leveled.

[0061] Dynamic adjustment: During the lifting process, the platform will tilt slightly due to load changes, hydraulic pressure fluctuations, etc. The feedback system will dynamically adjust the legs to ensure that the platform always remains within the allowable inclination range.

[0062] Tilt monitoring and alarm module, which is used to monitor the tilt angle of the platform in real time and issue an alarm when excessive tilt occurs;

[0063] Specifically, it includes a sensor detection unit, a sensor responsible for measuring the inclination, including:

[0064] Accelerometer: used to measure the acceleration changes of an object in three directions and calculate the tilt angle through the acceleration data.

[0065] Gyroscope: Used to measure changes in the rotational angle of an object, which can help detect tilt or tilt changes more accurately.

[0066] Tilt sensor: specially designed to measure the tilt angle of an object. Common types include capacitive, piezoelectric, and fiber optic.

[0067] The data acquisition unit is responsible for collecting the analog or digital signals output by the sensor and converting them into digital data that can be further processed.

[0068] Analog to digital converter, converts the analog signal of the sensor into a digital signal.

[0069] The data processing unit is used to process the collected tilt data through an algorithm to determine whether the current tilt exceeds a preset threshold. It includes:

[0070] The microcontroller is responsible for processing sensor data in real time, calculating the tilt angle, and comparing it with the preset threshold.

[0071] The tilt calculation algorithm calculates the tilt angle of an object through three-axis acceleration data, or obtains the tilt change by integrating the angular velocity of the gyroscope.

[0072] Alarm and display unit, when the tilt exceeds the set threshold, the alarm unit is responsible for issuing an alarm, including: sound and light alarm: buzzer, warning light, display screen: displays the current tilt angle and alarm information. Remote notification: alarm information is sent to a remote terminal such as a mobile phone, computer or monitoring center via wireless communication.

[0073] The fault diagnosis and self-check module is used to provide equipment self-check and fault diagnosis functions to ensure that the platform is always in good working condition during operation.

[0074] The device and lifting components are made of insulating materials, which can effectively block the current and prevent electric shock accidents caused by the platform contacting live equipment or cables, thereby ensuring the life safety of operators.

[0075] Working principle: Two special crawlers 1 are installed at the bottom of the chassis 9. These special crawlers 1 provide excellent traction to ensure that the lifting platform can move stably on soft, slippery or complex ground with large slopes. The design of the special crawlers 1 enables the platform to smoothly cross different terrains, thereby improving the platform's maneuverability and adaptability;

[0076] By starting the first hydraulic cylinder 11, since the output end of the first hydraulic cylinder 11 is connected to the articulated rod 10, when the first hydraulic cylinder 11 is working, the liquid pressure pushes the articulated rod 10 to rotate, thereby driving the top plate 7 to move up and down, thereby adjusting the height of the platform to meet different work requirements. In order to ensure the stability of the work platform, the height of the platform's railing can be adjusted through the adjustment component;

[0077] The servo motor 8 drives the transmission shaft 19 to rotate, and the gear 23 engages with the rack plate 20, so that the movable rod 16 slides in the installation cavity 21 to adjust the height of the railing. This adjustment component enables the platform to quickly adjust the railing as needed to adapt to different working environments.

[0078] The wind speed sensor 3 monitors the wind speed in the environment in real time, and outputs an electrical signal proportional to the wind speed according to the change of wind speed. The control box 2 adjusts the operating state of the lifting platform according to the signal, thereby ensuring the safe operation of the platform under different weather conditions. The temperature and humidity sensor 22 is responsible for measuring the ambient humidity and temperature to further optimize the working parameters of the platform. This system ensures that the platform can cope with external environmental factors such as changes in wind speed and humidity, and improves the safety and efficiency of operations.

[0079] The electric winch 15 ensures that the platform can move smoothly in complex terrain or perform necessary traction operations. In addition, the platform's operation control system is set on the top plate 7, and the operating table 5 is equipped with a forward and backward operating lever 17 and an acceleration and deceleration operating lever 18. The operator can easily control the platform's forward and backward movement and speed adjustment by operating these control levers, thereby ensuring the platform's flexibility and accuracy in aerial operations.
