Description

Technical Field

[0001] This invention relates to the field of engineering machinery technology, and in particular to a scissor lift aerial work platform, a control method, a storage medium, and a processor. Background Technology

[0002] Scissor lifts are a widely used type of lifting machinery. They have lifting capabilities and can be stopped at any point within their lifting range, facilitating construction. Currently, scissor lifts are widely used in shipbuilding, construction, municipal engineering, power, telecommunications, landscaping, stadiums, airports, ports, fire protection and advertising installations, and various large industrial and mining enterprises.

[0003] Scissor lifts are typically designed for indoor use only, or for operation at a single height outdoors. However, this design has significant limitations. Platforms designed for indoor use only, or for operation at a lower outdoor height, cannot meet the needs of outdoor operations at various heights; while allowing full-height outdoor use requires increasing the overall weight to ensure safety, but this increased weight leads to a significant increase in manufacturing costs. Summary of the Invention

[0004] This invention provides a scissor lift aerial work platform, a control method, a storage medium, and a processor to address the limitations of existing scissor lift aerial work platforms that are limited to indoor or single-height outdoor use, as well as the increased weight and manufacturing costs associated with full-height outdoor use. This invention expands the application scenarios for scissor lift aerial work platforms, improves their adaptability, and reduces the risk of tipping over during operation.

[0005] This invention provides a scissor lift aerial work platform, comprising: The work platform body is used to carry workers or materials; A chassis, which is mounted on the mobile device; A scissor lift mechanism, which is connected between the chassis and the work platform body; A drive component is connected to the scissor lift mechanism, and the drive component is used to drive the scissor lift mechanism to lift the work platform body. A mode setting component is used to set the working mode of the scissor lift aerial work platform, including an indoor working mode and an outdoor working mode. A weighing mechanism is provided on the work platform body, and the weighing mechanism is used to collect the working load of the work platform body when the outdoor working mode starts. The control system is communicatively connected to the weighing mechanism, the drive component, and the mode setting component, and automatically matches different preset lifting height limits according to different working loads.

[0006] According to the present invention, when the scissor lift aerial work platform is in an outdoor working state, the control system is configured with n load thresholds and n lifting height thresholds, where n≥2, and the n load thresholds correspond one-to-one with the n lifting height thresholds. Wherein, the n load thresholds are w1, w2, w3, ... and wn in sequence, and w1 > w2 > w3 > ... > wn; The n lifting height thresholds are hn, hn-1, ..., h2, h1, and hn < hn-1 < ... < h2 < h1; When the control system detects that the working load wx of the scissor lift platform satisfies wx≤wn, it controls the lifting height hx≤h1 of the scissor lift platform.

[0007] According to the present invention, a scissor lift aerial work platform further includes an angle sensor, which is disposed on the scissor lifting mechanism and is used to collect the angle information of the scissor lifting mechanism in real time.

[0009] The present invention also provides a control method for a scissor lift aerial work platform, comprising the following steps: Configure the working mode of the aerial work platform using the mode setting component; The operating mode of the aerial work equipment is determined according to the mode selection command. The operating modes include indoor operating mode and outdoor operating mode. The upper limit of the lifting height of the scissor lift mechanism is determined according to the working mode. When the working mode is indoor, the upper limit of the lifting height is the full height. When the working mode is outdoor, the upper limit of the lifting height is set to a preset upper limit of the lifting height corresponding to the size of the working load. When the lifting height of the scissor lift reaches the upper limit, the scissor lift mechanism is controlled to stop lifting.

[0010] According to the control method of the scissor lift aerial work platform provided by the present invention, when the working mode is outdoor working mode, the method further includes the following steps: Receive the working load signal from the weighing mechanism to determine the magnitude of the working load; The working load signal is compared with a preset load threshold to determine the preset upper limit of the lifting height corresponding to the working load signal; Receive the lifting height signal from the scissor lift mechanism and determine the lifting height; Compare the lifting height signal with the preset lifting height limit; When the lifting height reaches the preset upper limit, the scissor lift will stop lifting.

[0011] According to the control method of the scissor lift aerial work platform provided by the present invention, an angle sensor is installed on the scissor arm connected to the chassis of the scissor lifting mechanism. The scissor lifting mechanism detects the rotation angle of the scissor arm relative to the horizontal plane or the chassis in real time through the angle sensor to determine the lifting height.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0027] The following is combined Figures 1 to 4 The present invention provides a detailed description of a scissor lift aerial work platform, control method, storage medium, and processor through specific embodiments and application scenarios.

[0028] In embodiments of the present invention, such as Figure 1As shown, a scissor lift aerial work platform 10 includes a work platform body 11, a chassis 12, a scissor lifting mechanism 14, a drive assembly 15, a mode setting assembly, a weighing mechanism, and a control system. The work platform body 11 is used to carry workers or materials. The chassis 12 is mounted on a mobile device 13. The scissor lifting mechanism 14 is connected between the chassis 12 and the work platform body 11. The drive assembly 15 is connected to the scissor lifting mechanism 14 and is used to drive the scissor lifting mechanism 14 to raise and lower the work platform body 11. The mode setting assembly is used to set the working mode of the scissor lift aerial work platform 10, which includes an indoor working mode and an outdoor working mode. The weighing mechanism is mounted on the work platform body 11 and is used to collect the working load of the work platform body 11 when the outdoor working mode begins. The control system is communicatively connected to the weighing mechanism, the drive assembly 15, and the mode setting assembly, and automatically matches different preset upper limits of lifting height according to different working loads.

[0029] The work platform body 11 is the load-bearing component of the entire scissor lift aerial work platform 10, and its most direct function is to carry workers or materials. In various high-altitude work scenarios, workers need to stand on the work platform body 11 to operate; at the same time, some materials that need to be transported to high places are also placed on the work platform body 11 to ensure the safety and stability of personnel and materials during the operation.

[0030] The chassis 12 is mounted on the mobile device 13, providing a stable support foundation for the entire scissor lift aerial work platform 10. The mobile device 13 (such as wheels, tracks, etc.) is installed under the chassis 12, enabling the platform to move flexibly on the ground, facilitating its transport to different work locations, and improving the equipment's versatility and operational efficiency.

[0031] The chassis 12 serves as the connecting base for the scissor lift mechanism 14, connecting the scissor lift mechanism 14 with the moving device 13, making the entire platform an organic whole, and ensuring the stability of the relative positions of the components during lifting and moving.

[0032] The scissor lift mechanism 14 is connected between the chassis 12 and the work platform body 11, and is the component that enables the work platform body 11 to be raised and lowered. Through the action of the drive assembly 15, the scissor arms of the scissor lift mechanism 14 can extend or retract relative to each other, thereby driving the work platform body 11 to move up or down in the vertical direction to meet the needs of high-altitude operations at different heights.

[0033] The drive assembly 15 is connected to the scissor lift mechanism 14, and its function is to provide power to the scissor lift mechanism 14 to drive the extension and retraction of the scissor arms. Optionally, the drive assembly 15 can be a hydraulic cylinder, electric push rod, or other device, and the extension and retraction movement of these devices can drive the scissor lift mechanism 14 to achieve the lifting and lowering of the work platform body 11.

[0034] The mode setting component is used to set the working modes of the scissor lift aerial work platform 10, including indoor working mode and outdoor working mode. Different working modes correspond to different working environments and requirements. Through the mode setting component, operators can select the appropriate working mode according to the actual working scenario, enabling the platform to better adapt to various working conditions.

[0035] When different operating modes are selected, the mode setting component will transmit the corresponding signals to the control system. The control system will trigger the corresponding control strategy based on the received signals and adjust the equipment's operating parameters, such as lifting height limit and speed control, to ensure the safe and efficient operation of the equipment in different operating modes.

[0036] The weighing mechanism is located on the work platform body 11 and is mainly used to collect the working load of the work platform body 11 at the start of outdoor work mode. In outdoor working environments, due to factors such as ground conditions and wind, the safety requirements of the equipment are higher. By collecting the weight information on the work platform body 11 in real time through the weighing mechanism, the load-bearing status of the equipment can be understood in a timely manner.

[0037] The weighing mechanism transmits the collected working load data to the control system. The control system analyzes and judges the data to provide a basis for subsequent lifting height control, ensuring that the equipment operates within a safe load range.

[0038] The control system is communicatively connected to the weighing mechanism, drive assembly 15, and mode setting assembly, acting as an information hub. Through communication with each assembly, the control system can acquire the working load data collected by the weighing mechanism and the working mode information set by the mode setting assembly in real time, and send control commands to the drive assembly 15 to achieve coordinated operation among the assemblies.

[0039] The control system automatically matches different preset lifting height limits according to different working loads. In outdoor working mode, after the weighing mechanism collects the working load of the work platform body 11, the control system calculates the maximum allowable lifting height under the load according to the preset algorithm and safety standards, and controls the drive component 15 to limit the lifting height of the work platform body 11, so as to avoid tipping over due to excessive load and excessive lifting, thereby reducing the risk of tipping over during operation and improving the safety and reliability of the equipment.

[0040] This application's scissor lift aerial work platform 10 supports both indoor and outdoor working modes via a mode setting component. In outdoor mode, a weighing mechanism is mounted on the platform body 11 to collect the working load of the platform body 11 at the start of outdoor working mode. Simultaneously, the control system is communicatively connected to both the weighing mechanism and the drive component 15, and automatically matches different preset lifting height limits according to different working loads. In this way, when working outdoors, the lifting height is limited based on the actual load, avoiding tipping due to excessive load and excessive lifting height, thereby reducing the risk of tipping during operation.

[0041] In some embodiments, when the scissor lift aerial work platform 10 is in an outdoor working state, the control system is configured with n load thresholds and n lifting height thresholds, where n≥2, and the n load thresholds correspond one-to-one with the n lifting height thresholds; Wherein, the n load thresholds are w1, w2, w3, ... and wn in sequence, and w1 > w2 > w3 > ... > wn; The n lifting height thresholds are hn, hn-1, ..., h2, h1, and hn < hn-1 < ... < h2 < h1; When the control system detects that the working load wx of the scissor lift platform 10 satisfies wx≤wn, it controls the lifting height hx≤h1 of the scissor lift platform 10.

[0042] Understandably, by setting multiple load thresholds and corresponding lifting height thresholds, with the load thresholds decreasing sequentially (w1 > w2 > w3 > ... > wn) and the lifting height thresholds increasing sequentially (hn < hn-1 < ... < h2 < h1), a tiered limit on the lifting height is achieved based on different load conditions. When the working load is large, the corresponding upper limit of the lifting height is lower; when the working load is small, the corresponding upper limit of the lifting height is higher. This tiered control method can effectively prevent equipment tipping accidents caused by excessive load and excessive lifting height during outdoor operations, greatly improving operational safety.

[0043] The control system can dynamically adjust the upper limit of the lifting height based on the real-time detected workload, better adapting to different outdoor working environments. For example, in windy conditions, even with a light workload, the control system can appropriately reduce the upper limit of the lifting height according to preset rules to enhance the equipment's wind resistance and stability.

[0044] Reference Figure 1According to the present invention, a scissor lift aerial work platform 10 further includes an angle sensor 16, which is disposed on the scissor lifting mechanism 14 and is used to collect the angle information of the scissor lifting mechanism 14 rising in real time.

[0045] It is understandable that the lifting height of the scissor lift mechanism 14 has a fixed geometric relationship with the unfolding angle of the scissor arms. After the angle sensor 16 collects the angle information of the scissor lift mechanism 14 in real time, the control system can convert the angle value into accurate lifting height data based on a preset geometric model, providing a direct basis for judging whether the height has reached the threshold.

[0046] In outdoor operating mode, the control system has matched the corresponding upper limit of lifting height according to the load. The angle information fed back in real time by the angle sensor 16 is converted into height and compared with the upper limit value in real time: when the actual height is detected to be about to reach or exceed the upper limit, the control system can immediately send a stop command to the drive component 15 to avoid lifting beyond the upper limit.

[0047] Reference Figure 1 According to the present invention, a scissor lift aerial work platform 10 further includes an upper controller 17 and a lower controller 18. The upper controller 17 is disposed on the work platform body 11, and the lower controller 18 is disposed on the chassis 12. The upper controller 17 and the lower controller 18 are respectively connected to the control system.

[0048] Understandably, during operation of the scissor lift aerial work platform 10, operators may be in different positions. The upper controller 17 is located on the platform body 11, allowing operators to directly control the equipment's functions while working on the platform, such as adjusting the platform body's slight posture and controlling tools mounted on it. The lower controller 18 is located on the chassis 12. When operators are preparing or debugging the equipment on the ground, or when monitoring and operating it during the platform's descent, they can control the equipment through the lower controller 18, such as starting the equipment, selecting working modes, and controlling its movement. This dual-controller setup allows operators to conveniently operate the equipment whether on the platform or on the ground, improving operational flexibility and efficiency.

[0049] The control method of the scissor lift aerial work platform 10 provided by the present invention is described below. The control method of the scissor lift aerial work platform 10 described below can be referred to in correspondence with the scissor lift aerial work platform 10 described above.

[0050] Reference Figure 2 and Figure 3The present invention also provides a control method for a scissor lift aerial work platform 10, comprising the following steps: Configure the working mode of the aerial work platform using the mode setting component; The operating mode of the aerial work equipment is determined according to the mode selection command. The operating modes include indoor operating mode and outdoor operating mode. The upper limit of the lifting height of the scissor lift mechanism 14 is determined according to the working mode. When the working mode is indoor working mode, the upper limit of the lifting height is the full height. When the working mode is outdoor working mode, the upper limit of the lifting height is set to a preset upper limit of the lifting height corresponding to the size of the working load. When the lifting height of the scissor lift mechanism 14 reaches the upper limit of the lifting height, the scissor lift mechanism 14 is controlled to stop lifting.

[0051] Understandably, setting the working mode of an aerial work platform through mode setting components provides users with an intuitive and convenient way to express their desired work scenarios and needs. Mode setting components (such as buttons on the control panel, options on the touch screen, etc.) establish an interactive bridge between users and the equipment, enabling users to quickly and accurately set the working mode according to the actual working environment (indoor or outdoor), providing basic input information for subsequent control logic.

[0052] The operating mode of the aerial work platform is determined based on the mode selection command. This includes indoor and outdoor operating modes. This step processes and parses the commands input by the user through the mode setting component, converting them into an operating mode recognizable by the equipment. Clearly distinguishing between indoor and outdoor operating modes helps in developing differentiated control strategies for different scenarios. Because indoor and outdoor operating environments differ significantly, such as space limitations, ground conditions, and wind influences, differentiating the operating mode is a crucial prerequisite for subsequent targeted control.

[0053] The upper limit of the lifting height of the scissor lift mechanism 14 is determined according to the operating mode. In indoor operating mode, the upper limit is the full height. In outdoor operating mode, the upper limit is set to a preset upper limit corresponding to the workload. In indoor operations, the space is typically relatively enclosed, with less external interference from wind; therefore, the limitation on the lifting height primarily considers the equipment's structure and safety performance. Setting the upper limit to the full height allows for full utilization of the equipment's performance, meets the operational needs at different indoor heights, and improves operational efficiency and flexibility.

[0054] The outdoor environment is complex and changeable, with factors such as wind force and ground stability significantly impacting the safety of aerial work platforms. The size of the working load is closely related to the stability and wind resistance of the equipment. Setting an appropriate upper limit for the lifting height based on the working load is a safety precaution. When the working load is large, lowering the upper limit of the lifting height can reduce the risk of the equipment overturning under external forces such as wind, ensuring operational safety. The preset upper limit of the lifting height is determined based on the equipment's performance parameters and extensive experimental data, enabling a reasonable balance between operational needs and safety requirements under different load conditions.

[0055] When the lifting height of the scissor lift mechanism 14 reaches its upper limit, the mechanism stops lifting. By monitoring the lifting height of the scissor lift mechanism 14 in real time and stopping the lifting action promptly when the preset upper limit is reached, overloading or exceeding the limits of the equipment can be effectively prevented. Overloading or exceeding the limits of the equipment may lead to serious safety accidents such as structural damage or overturning, endangering the lives of operators and surrounding personnel. This step ensures that the equipment operates within a safe range and is an important measure to ensure the safety of high-altitude operations.

[0056] In one embodiment, the control method for a scissor lift aerial work platform 10 according to the present invention further includes the following steps when the working mode is outdoor working mode: Receive the working load signal from the weighing mechanism to determine the magnitude of the working load; The working load signal is compared with a preset load threshold to determine the preset upper limit of the lifting height corresponding to the working load signal; Receive the lifting height signal fed back by the scissor lift mechanism 14 and determine the lifting height; Compare the lifting height signal with the preset lifting height limit; When the lifting height reaches the preset upper limit, the scissor lift platform 10 will stop lifting.

[0057] It is understandable that the working load signal received from the weighing mechanism is used to determine the size of the working load. This provides basic data for subsequent judgments on whether the working load exceeds the safe range and for determining the corresponding upper limit of the lifting height.

[0058] The working load signal is compared with a preset load threshold to determine the corresponding preset lifting height upper limit. Based on the comparison result, a suitable preset lifting height upper limit is determined. This is because the larger the working load, the greater the force the platform bears during lifting. To ensure the stability and safety of the platform during outdoor operations, its lifting height needs to be limited. Through this comparison and correspondence, the upper limit of the lifting height can be dynamically adjusted according to the actual working load, avoiding safety accidents caused by excessive load and excessive lifting height.

[0059] The system receives the lifting height signal from the scissor lift mechanism 14, determines the lifting height, and acquires the current lifting height information of the scissor lift mechanism 14 in real time for comparison with the preset upper limit of lifting height, thereby determining whether the platform has reached the maximum allowable lifting height. This ensures timely monitoring of the platform's lifting status.

[0060] The lifting height signal is compared with the preset lifting height limit. By comparing the current lifting height with the preset lifting height limit, it is determined whether the platform is approaching or has reached the safe lifting limit. This provides a basis for subsequent control actions.

[0061] When the lifting height reaches the preset upper limit, the scissor lift platform 10 stops lifting. The platform stops lifting in time when the lifting height reaches the preset upper limit, which effectively prevents the platform from exceeding its safe load-bearing range due to excessive lifting, avoids serious safety accidents such as overturning, ensures the safety of operators and equipment, and ensures the stable operation of the platform in outdoor working environments.

[0062] In one embodiment, according to a control method for a scissor lift aerial work platform 10 provided by the present invention, an angle sensor 16 is installed on the scissor arm connected to the chassis 12 by the scissor lifting mechanism 14. The scissor lifting mechanism 14 detects the rotation angle of the scissor arm relative to the horizontal plane or the chassis 12 in real time through the angle sensor 16 to determine the lifting height.

[0063] Understandably, the angle sensor 16 can directly measure the rotation angle of the scissor lift arm relative to the horizontal plane or the chassis 12. Due to the structural characteristics of the scissor lift mechanism 14, its lifting height has a definite geometric relationship with the rotation angle of the scissor lift arm. Through a pre-set mathematical model or formula, the rotation angle measured by the angle sensor 16 is accurately converted into the lifting height of the scissor lift mechanism 14. This measurement method avoids the cumulative errors that may exist in traditional measurement methods and can provide more accurate height information.

[0064] During the operation of the scissor lift aerial work platform 10, various complex working conditions may be encountered, such as uneven ground and tilted chassis 12. The angle sensor 16, mounted on the scissor arm, measures the angle without being affected by factors such as chassis 12 tilt, consistently and accurately reflecting the rotation angle of the scissor arm relative to the horizontal plane, thus accurately determining the lifting height. This allows the platform to obtain reliable height data in different working environments, improving the adaptability and accuracy of the measurement.

[0065] Figure 4 An example is a schematic diagram of the physical structure of an electronic device, such as... Figure 4 As shown, the electronic device may include a processor 810, a communications interface 820, a memory 830, and a communication bus 840. The processor 810, communications interface 820, and memory 830 communicate with each other via the communication bus 840. The processor 810 can call logical instructions in the memory 830 to execute a control method for the scissor lift platform 10. This method includes: setting the working mode of the aerial work platform through a mode setting component; determining the working mode of the aerial work equipment according to the mode selection instruction, including an indoor working mode and an outdoor working mode; determining the upper limit of the lifting height of the scissor lift mechanism 14 according to the working mode, wherein when the working mode is indoor, the upper limit of the lifting height is the full height; when the working mode is outdoor, the upper limit of the lifting height is set to a preset upper limit corresponding to the working load size; and controlling the scissor lift mechanism 14 to stop lifting when the lifting height reaches the upper limit.

[0066] Furthermore, the logical instructions in the aforementioned memory 830 can be implemented as software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of the present invention, or the part that contributes to the prior art, or a part of the technical solution, can be embodied in the form of a software product. This computer software product is stored in a storage medium and includes several instructions to cause a computer device (which may be a personal computer, server, or network device, etc.) to execute all or part of the steps of the methods described in the various embodiments of the present invention. The aforementioned storage medium includes various media capable of storing program code, such as USB flash drives, portable hard drives, read-only memory (ROM), random access memory (RAM), magnetic disks, or optical disks.
