Anti-tipping control methods, devices, equipment and media for aerial work platforms
[0001] This application claims priority to Chinese Patent Application No. 202411448323.7, filed on October 17, 2024, the entire contents of which are incorporated herein by reference. Technical Field
[0002] This application relates to the field of engineering machinery technology, such as a method, device, equipment and medium for preventing tipping over of an aerial work platform. Background Technology
[0003] In aerial work platforms of related technologies, the boom unit and the turntable unit are usually rigidly connected. The boom unit rotates around a fixed pin mounted on the turntable to reach a specified angle position. However, under different tilting application conditions, the whole machine is limited by the working range of the boom unit and cannot flexibly adjust the stabilizing torque to counteract the tilting torque.
[0004] Meanwhile, the permissible tilt range of currently available aerial work platforms is relatively small, imposing strict limitations on the working environment. To improve the safety and stability of aerial work platforms, counterweight units are added to the turntable unit to make the platform's center of gravity more stable. However, the selection of counterweight weight is not flexible enough, resulting in poor effectiveness in reducing the impact of slopes on the platform's tilt. Furthermore, when the counterweight weight is too high, it leads to a waste of the machine's energy consumption. Summary of the Invention

[0034] Before introducing the specific embodiments of this application, the aerial work platform of this application will be described with reference to Figure 2.

[0035] Example 1
[0036] Figure 1 is a flowchart of an anti-tipping control method for an aerial work platform provided in Embodiment 1 of this application. This embodiment is applicable to the situation of adaptive movement control of an aerial work platform. The method can be executed by an anti-tipping control device for the aerial work platform. The device can be implemented in hardware and / or software and can be configured in an adaptively movable aerial work platform. As shown in Figure 1, the method includes:
[0037] S110. Obtain the center of gravity position and weight of each functional unit under the current aerial work platform; wherein each functional unit includes: work platform, boom unit, hinge unit, counterweight unit, turntable unit and chassis unit.
[0038] Aerial work platforms in related technologies typically consist of a work platform, a boom unit, a turntable unit, and a chassis unit from top to bottom. In this embodiment, the hinge unit refers to a functional unit that can drive the upper boom unit and the work platform to move horizontally within the turntable unit's track. The movement distance of the hinge unit is flexibly adjusted to offset some of the overturning moment. The counterweight unit can be pre-set with an appropriate weight to balance the overall machine's torque. Flexibly adjusting the weight of the counterweight unit allows the entire system to output the most reasonable energy consumption, thereby improving the machine's endurance. Therefore, the counterweight unit and the hinge unit are described as separate functional execution units. A structural reference diagram of the aerial work platform in this embodiment is shown in Figure 2.
[0039] S120. Collect the rotation angle of the whole machine, and select the corresponding tilt line calculation formula according to the angle range in which the rotation angle falls, and calculate the tilt line of the whole machine.
[0040] In this embodiment, a rotation angle sensor is installed at the connection between the turntable unit and the chassis unit to monitor the relative angle between them in real time. This sensor allows for the real-time acquisition of the overall rotation angle. The rotation angle is pre-divided into multiple intervals, and different tilt line calculation formulas are set for each interval. When the rotation angle is determined, an angle interval is defined based on that angle, and the tilt line position of the entire machine can be calculated using the corresponding tilt line calculation formula. The overall tilt line refers to a baseline for the machine to achieve balance under different tilting conditions. Tilting moments and stabilizing moments are distributed on both sides of the overall tilt line.
[0041] In some embodiments, since the counterweight unit, boom unit, etc. are all connected to the turntable unit through rigid pins, they together form a superstructure. Therefore, the rotation angle of the whole machine refers to the relative rotation angle between this superstructure, which includes the turntable unit and all the units connected to it, and the chassis unit.
[0042] In some embodiments, the rotation angle of the entire machine is collected, and the corresponding tilt line calculation formula is selected according to the angle range in which the rotation angle falls, to calculate the tilt line of the entire machine, which may include:
[0043] Obtain the wheelbase of the front and rear axles, the track width between the left and right tires, and the cross-sectional width of the tires in the chassis unit.
[0044] The rotation angle is calculated by using a rotation angle sensor installed at the connection between the turntable unit and the chassis unit.
[0045] Select the corresponding tipping line calculation formula based on the angle range in which the rotation angle falls, and use at least one of the rotation angle, wheelbase, track width, and cross-sectional width, along with the tipping line calculation formula, to determine the position of the overall machine tipping line.
[0046] Define the wheelbase between the front and rear axles in the chassis unit as P, the distance between the center planes of the left and right tires of the front and rear axles as the track width Q, the cross-sectional width of the tire as O, and the tilt line of the whole machine as K.
[0047] For example, when the turntable unit and the chassis unit of the whole machine are at 0° or 180° (parallel), that is, the rotation angle α is within the angle range of 0° or 180°, the tilt line K of the whole machine can be defined as half of the wheelbase, that is: When the turntable unit of the entire machine is perpendicular to the chassis unit at 90° or 270°, that is, when the rotation angle α is within the angle range of 90° or 270°, the tilt line K of the entire machine can be defined as half of the wheelbase plus one-quarter of the tire width, that is: When the turntable unit and chassis unit of the whole machine are not parallel or perpendicular during rotation, assuming the turntable unit rotates counterclockwise relative to the chassis unit, if the rotation angle α falls within the range of [315°, 45°) or [135°~225°), the tilting line K of the whole machine can be determined according to... To determine; if the rotation angle α falls within the range of [45°~135°) or [225°~315°), the tilting line K of the whole machine can be determined according to To determine.
[0048] Where α is the value fed back by the rotation angle sensor installed at the connection between the turntable unit and the chassis unit.
[0049] S130. Obtain the real-time tilt status of the whole machine based on the tilt angle sensor on the turntable unit, and select the corresponding torque calculation formula based on the real-time tilt status of the whole machine.
[0050] In this embodiment, a tilt angle sensor is installed on the turntable unit to measure the tilt angle of the work platform and monitor the tilt state of the entire machine in real time. The tilt state can refer to two tilting methods, and each of the two different tilting methods corresponds to a separate torque calculation formula.
[0051] In some embodiments, the real-time tilt state of the entire machine is obtained based on the tilt angle sensor on the turntable unit, and a corresponding torque calculation formula is selected based on the real-time tilt state of the entire machine, which may include:
[0052] When the machine is tilted in a positive direction in real time, the torque calculation formula is M1 = G × (Xcosθ - Zsinθ).
[0053] When the real-time tilt of the whole machine is negative, M2=-G×(Xcosθ+Zsinθ) is selected as the torque calculation formula;
[0054] Specifically, when the angle θ collected by the tilt angle sensor is within the range of [-90°, 0°), the real-time tilt state of the whole machine is determined to be negative tilt; when the angle θ collected by the tilt angle sensor is within the range of [0°, 90°), the real-time tilt state of the whole machine is determined to be positive tilt.
[0055] Where G is the weight of each functional unit; θ is the angle collected by the tilt angle sensor; X and Z are the abscissa and ordinate values of the center of gravity of each functional unit relative to the tilt line of the whole machine in the torque calculation plane, respectively.
[0056] In some embodiments, a two-dimensional coordinate system is established in a moment calculation plane (used for longitudinal or lateral force analysis) perpendicular to the contact horizontal plane, with the overall tilting line K as the reference: the origin is set as a fixed point on the overall tilting line (the intersection point O of the overall tilting line and the contact horizontal plane as shown in Figure 2-4); the horizontal coordinate X is set along the horizontal direction perpendicular to the overall tilting line, and X is positive when the center of gravity of each functional unit is to the right of the overall tilting line, negative when it is to the left of the overall tilting line, and 0 when it falls on the overall tilting line; the vertical coordinate Z is set along the vertical direction perpendicular to the contact horizontal plane, and Z is positive when the center of gravity of each functional unit is above the contact horizontal plane, negative when it is below the contact horizontal plane, and 0 when it falls on the contact horizontal plane, so as to quantify the spatial position of the center of gravity of each functional unit relative to the overall tilting line.
[0057] For example, the angle collected by the tilt angle sensor is denoted as θ. When θ is in the range of [0°, 90°), the whole machine is defined as being in a positive tilt state, as shown in Figure 3; when θ is in the range of [-90°, 0°), the whole machine is defined as being in a negative tilt state, as shown in Figure 4.
[0058] S140. Obtain the center-of-gravity coordinates of each functional unit according to the tilting line of the whole machine, and substitute the center-of-gravity coordinates of each functional unit, the weight of each functional unit, and the angle collected by the tilt angle sensor into the torque calculation formula to calculate the torque of each functional unit.
[0059] As shown in S130, (X, Z) can be the center of gravity position of each functional unit, representing the horizontal and vertical coordinates of the unit on the torque calculation plane, with the overall tilting line as the reference. When solving for the torque of each functional unit, the torque calculation formula of M1 or M2 can be selected according to different tilt states.
[0060] In some embodiments, the torque of each functional unit refers to the torque calculated relative to the tilting line of each functional unit (such as the counterweight unit, boom unit, etc.) included in the whole machine based on its own weight and center of gravity position, as well as the angle data collected by the tilt angle sensor.
[0061] In some embodiments, the torques generated by each functional unit are divided based on the overall tilting line: when the center of gravity of a functional unit is located on the tilting side of the tilting line, the torque generated by that functional unit is a tilting torque; when the center of gravity of a functional unit is located on the stabilizing side of the tilting line, the torque generated by that functional unit is a stabilizing torque. For example, in a forward tilting condition, the center of gravity of the working platform is located on the tilting side of the tilting line, and the torque it generates is a tilting torque; the center of gravity of the counterweight unit is located on the stabilizing side of the tilting line, and the torque it generates is a stabilizing torque.
[0062] S150. Based on the real-time tilt state of the whole machine, determine the composition of the overturning moment and the stabilizing moment used to counteract the overturning moment; wherein, the functional unit moment is either the overturning moment or the stabilizing moment.
[0063] In some embodiments, under different tilting conditions, the total moment that may cause the entire machine to tilt, composed of the overall tilting moment (i.e., the sum of the tilting moments generated by all functional units on the tilting side), environmental moments, and operating moments, is called the tilting moment; while the total moment used to counteract the tilting moment and keep the entire machine stable is called the stabilizing moment. When the total tilting moment is equal to the total stabilizing moment, the entire machine is in a critical stable state.
[0064] In the embodiments of this application, the torque of each functional unit may serve as either a tipping torque or a stabilizing torque under different application conditions. For example, depending on different tilt states, the torque generated by the counterweight unit can serve as either a tipping torque or a stabilizing torque.
[0065] In some embodiments, determining the overturning moment and the stabilizing moment to counteract the overturning moment based on the real-time tilt state of the entire machine may include:
[0066] Obtain the maximum wind force and maximum manual operating force of the whole machine under real-time tilt state, and calculate the corresponding environmental torque and operating torque respectively;
[0067] In response to the overall machine tilting in a positive direction, the tilting moment consists of the overall machine tilting moment, the environmental moment, and the operating moment, while the stabilizing moment consists of the chassis moment, the turntable moment, and the counterweight moment.
[0068] In response to the overall machine tilting in a negative direction, the overturning moment consists of the overall machine overturning moment, the environmental moment, and the operating moment, while the stabilizing moment consists of the hinge point moment, the chassis moment, the turntable moment, the boom moment, and the working platform moment.
[0069] During operation, the machine is affected not only by the tipping force from the inclined slope, but also by the wind force and the manual operating force. The environmental torque is the torque generated by the maximum wind force, and the operating torque is the torque generated by the maximum manual operating force. Furthermore, the direction of the torques generated by each functional unit changes under different tilt conditions. Therefore, it is necessary to determine the composition of the tipping torque and stabilizing torque under the two tilt conditions.
[0070] For example, when the machine is tilted in the positive direction, the tilting moment of the machine may include the hinge point moment, the working platform moment, and the boom moment; when the machine is tilted in the negative direction, the tilting moment of the machine may include the counterweight moment.
[0071] S160. The moving distance of the hinge unit is determined by calculating the difference between the stabilizing torque and the overturning torque, so that the whole machine can reach balance.
[0072] In some examples, taking the vehicle tilting forward as an example, the tilting moment equals the overall tilting moment plus the environmental moment plus the operating moment. The overall tilting moment can include the hinge point moment, the work platform moment, and the boom moment. The stabilizing moment equals the chassis moment plus the turntable moment plus the counterweight moment. The stabilizing moment must be equal to the tilting moment to ensure the overall balance of the machine. In the current tilted state, the tilting moment and the chassis moment, turntable moment, and counterweight moment in the stabilizing moment are all known. The only moment that can be flexibly adjusted is the moment associated with the movement of the hinge point unit. The hinge point unit itself is relatively light, and its movement will not directly have a significant impact on the overall moment balance. The key is that it will drive the connected boom unit and work platform to move synchronously. This linkage process will cause changes in the (X, Z) coordinates of the boom unit and work platform, which in turn will lead to changes in the environmental moment (related to the windward area) and the operating moment (related to the operating height), ultimately reducing the overall tilting moment of the machine. The associated torque generated by the linkage adjustment of the hinge unit offsets the difference between the overturning torque and the stabilizing torque. At this point, the associated torque is the critical value at which the balance is just achieved.
[0073] Under specific operating conditions, provided that the machine is kept in balance, the operator can control the hinge unit to move within the track of the turntable unit according to actual needs. The movement of the hinge unit drives the upper boom unit and the work platform to achieve a wider range of operations, improving both safety and work efficiency.
[0074] In some embodiments, determining the movement distance of the hinge unit by calculating the difference between the stabilizing moment and the overturning moment to achieve overall balance may include:
[0075] In response to the machine tilting in the positive direction, the first difference torque between the stabilizing torque and the overturning torque is calculated, and the hinge unit is controlled to move a first distance in the negative direction according to the first difference torque, so that the machine can reach balance.
[0076] In response to the machine tilting in the negative direction, the second difference torque between the stabilizing torque and the overturning torque is calculated, and the hinge unit is controlled to move a second distance in the positive direction according to the second difference torque, so that the machine can reach balance.
[0077] The direction of movement of the hinge unit is determined according to the tilting direction of the whole machine, so as to ensure that the associated torque generated by the linkage adjustment of the hinge unit can be used to counteract the first differential torque or the second differential torque.
[0078] This embodiment of the application, by pre-setting calculation formulas for the overall tilting line under different angle ranges, can determine the overall tilting line of the machine in its current state, and obtain the center-of-gravity coordinates of each functional unit using the overall tilting line as a baseline. Simultaneously, by pre-setting torque calculation formulas for two tilting states, the torque generated by each functional unit and the entire machine can be determined, and the movement of the hinge unit can be controlled by analyzing the composition of the tilting torque and stabilizing torque, so that the entire machine reaches a balanced state. This embodiment of the application, by acquiring the overall machine status in real time, can adaptively control the movement of the hinge unit. During the movement of the hinge unit, the boom unit and the work platform move, thus increasing the working range of the boom unit and the work platform, maximizing the utilization rate of each functional unit while ensuring the safety and stability of the aerial work platform. Embodiment Two
[0079] Figure 5 is a flowchart of another anti-tipping control method for an aerial work platform provided in Embodiment 2 of this application. This embodiment is based on the above embodiment with adjustments. As shown in Figure 5, the method includes:
[0080] S510. In the application condition of positive tilt, control the hinge unit to move to the first edge in the negative direction, and record the first counterweight weight of the counterweight unit at this time.
[0081] When the angle θ collected by the tilt angle sensor on the turntable unit is within the range of [0°, 90°), the real-time tilt state of the whole machine is determined to be positive tilt.
[0082] As a functional unit that can adjust its weight before the start of formal operation, the counterweight unit optimizes the selection of the counterweight weight by simulating real working scenarios under two working conditions of the whole machine in advance. This ensures that the whole machine meets the stability requirements under the optimal counterweight weight in both application conditions, thereby achieving overall machine lightweighting.
[0083] In some embodiments, referring to the reference diagram (Figure 3) of the machine under positive tilt conditions, the positive tilt direction can be described as tilting to the right with the machine's tilting line as the baseline. In this case, the hinge unit needs to move to the left. The first edge of the hinge unit's movement is also the maximum distance the hinge unit moves towards the counterweight unit. Under this extreme condition, when the hinge unit moves the maximum distance in the negative direction, it drives the boom unit and the work platform to move synchronously through linkage, causing the machine's tilting moment to be reduced to a minimum, thereby offsetting part of the tilting moment to the maximum extent. That is, it offsets part of the tilting moment to the maximum extent. At this time, the minimum weight of the counterweight unit under positive tilt conditions is obtained, which is the first counterweight weight.
[0084] S520. In the application condition of negative tilt, control the hinge unit to move in the positive direction to the second edge, and record the weight of the second counterweight of the counterweight unit at this time.
[0085] When the angle θ collected by the tilt angle sensor on the turntable unit is within the range of [-90°, 0°), the real-time tilt state of the whole machine is determined to be negative tilt.
[0086] In some embodiments, referring to the reference diagram (Figure 4) of the machine under negative tilt conditions, the negative tilt direction can be described as tilting to the left with the machine's tilting line as the baseline. In this case, the hinge unit needs to move to the right. The second edge of the hinge unit's movement is also the maximum distance the hinge unit moves away from the counterweight unit. Under this extreme condition, when the hinge unit moves the maximum distance in the positive direction, it drives the boom unit and platform unit to move synchronously through linkage, so that the tilting moment of the machine (the moment generated by the counterweight unit at this time is the tilting moment) is offset to the greatest extent. That is, it can offset part of the tilting moment when the counterweight unit is the tilting moment to the greatest extent. At this time, the maximum weight allowed by the counterweight unit under the negative tilt condition is obtained, which is the second counterweight weight.
[0087] S530. If the aerial work platform can maintain balance in a positive tilt state under the weight of the second counterweight, then compare the values of the first counterweight weight and the second counterweight weight, and select the minimum value as the final counterweight unit weight.
[0088] To determine which weight is optimal for both extreme operating conditions between the first and second counterweights, the second counterweight weight obtained under the negative tilting condition is reapplied to the positive tilting condition. If the machine remains balanced when the counterweight unit weight is the second counterweight weight, it indicates that the stabilizing torque is still greater than the overturning torque. Since the torque generated by the counterweight unit is insufficient to offset the overturning torque, a smaller counterweight unit weight results in lower overall energy consumption. Therefore, selecting the smaller weight between the first and second counterweights satisfies the balance requirements under both operating conditions while maximizing energy savings.
[0089] S540. If the aerial work platform cannot maintain balance in a forward tilted state under the weight of the second counterweight, adjust the allowable travel of the hinge unit arranged on the turntable unit and control the hinge unit to continue moving from the first edge toward the counterweight unit.
[0090] If the second counterweight is applied to a forward tilting condition and the machine cannot achieve balance, it indicates that the tilting moment is greater than the stabilizing moment. In this condition, the torque generated by the counterweight unit is used to counteract the tilting moment, but the stabilizing moment generated by the second counterweight is far from sufficient to counteract the overall tilting moment generated in this condition, thereby reducing the total overall tilting moment. Simultaneously, since the hinge unit's initial position is at the first edge when the second counterweight is applied to a forward tilting condition, to restore balance, the allowable travel of the hinge unit on the turntable unit can be adjusted. This allows the hinge unit to continue moving from the first edge towards the counterweight unit, reducing the overall tilting moment of the aerial work platform in a forward tilting state, effectively reducing the first counterweight and thus the torque generated by the counterweight unit.
[0091] S550. When the aerial work platform regains balance under the condition of forward tilting, calculate the compensation torque generated by the movement of the hinge unit at this time.
[0092] The compensation torque generated by the movement of the hinge unit during the entire adjustment process from when the second counterweight weight is applied to the positive tilting condition and does not meet the balance state until the whole machine regains balance is obtained. This compensation torque can be regarded as acting to reduce the value of the overturning moment of the whole machine, so that the overturning moment is equal to the stabilizing moment.
[0093] S560. Calculate the weight of the third counterweight of the counterweight unit based on the compensation torque, and use the weight of the third counterweight as the final weight of the counterweight unit.
[0094] The compensation torque is actually the torque that the counterweight unit should reduce under the positive tilting condition. The corresponding compensation weight can be calculated based on the compensation torque. This compensation weight is actually the counterweight weight that the counterweight unit should reduce based on the first counterweight weight. The third counterweight weight is obtained by subtracting the first counterweight weight from the compensation weight. The third counterweight weight is the optimal weight of the counterweight unit when the second counterweight weight cannot meet the balance requirements under the positive tilting condition. At the same time, the allowable motion stroke of the hinge unit as a whole is determined.
[0095] S570: Collect the rotation angle of the whole machine, and select the corresponding tilt line calculation formula according to the angle range in which the rotation angle falls, to calculate the tilt line of the whole machine.
