Description

Technical Field

[0001] This application relates to the field of aerial work platforms, and more specifically to an aerial work platform, a control system, a control method, and a machine-readable storage medium. Background Technology

[0002] Telescopic boom forklifts are widely used, highly adaptable to different terrains, and flexible in operation. A telescopic boom forklift consists of a retractable boom and a platform at the top of the boom for carrying personnel to perform aerial work. To ensure personnel safety, telescopic boom forklifts are equipped with an anti-tipping system, of which the operating curve is a crucial component. For example... Figure 1 As shown, the operating curve describes the change in the horizontal length L of the boom as a function of the height H, depending on different load values, when the telescopic boom forklift is in a critical state of imminent tipping. The telescopic boom forklift uses the operating curve to determine whether the vehicle is at risk of tipping: if the real-time position coordinates of the boom tip are located in the tipping zone outside the operating curve, the vehicle is at risk of tipping; if the real-time position coordinates of the boom tip are located in the stable zone inside the operating curve, the vehicle is stable.

[0003] A retractable platform is a common multi-functional platform consisting of a main platform 1 and a secondary platform 2. When the secondary platform 2 is retracted into the main platform 1, it reduces the overall width of the retractable platform, improving the vehicle's maneuverability in narrow areas; when the secondary platform 2 is extended relative to the main platform 1, it provides a larger working space and operating range. Figure 2 The diagram shows the retracted and extended states of the telescopic forklift platform. The line connecting the ground contact points of the front wheels of the forklift is the preset tipping line C. In the retracted state, the load center is at point A, at a distance L1 from the preset tipping line C; in the extended state, the load center is at point B, at a distance L2 from the preset tipping line C, where L2 is greater than L1. Therefore, the tipping moment is greater in the extended state, making it more prone to tipping. This difference necessitates the use of different operating curves for the retracted and extended states to ensure operational safety. Currently, when using the telescopic forklift platform in the retracted state, the tipping decision curve is based solely on the operating curve in the extended state. This conservative approach narrows the operating range of the platform in the retracted state and fails to fully utilize the overall operational performance of the forklift. Summary of the Invention

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for illustration and explanation of the embodiments of this application and are not intended to limit the embodiments of this application.

[0050] In this application, the embodiments involve descriptions such as "first" and "second." These descriptions are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include at least one of those features. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, such a combination should be considered non-existent and not within the scope of protection claimed in this application.

[0051] like Figures 3 to 6 As shown, a control system for aerial work machinery includes:

[0052] Platform detection equipment is used to detect the real-time status of the extension and retraction platforms of aerial work platforms; and

[0053] The processing equipment communicates with the platform detection equipment and is configured to select different operation curves as the overturning judgment curves for aerial work machinery based on different real-time conditions.

[0054] In this application, the control system has preset different operating curves according to different forms of the deployment and retrieval platform. After the platform detection equipment detects the real-time form of the deployment and retrieval platform, the processing equipment selects the corresponding operating curve as the tipping judgment curve. Since the operating curve of the deployment and retrieval platform in the deployed form is no longer used alone as the tipping judgment curve, but the corresponding operating curve is selected according to the real-time form of the deployment and retrieval platform, the deployment and retrieval platform can always obtain the maximum working range under different real-time forms. This solves the problem of the single tipping judgment curve selection for aerial work platforms and achieves the effect of improving the working range of the deployment and retrieval platform.

[0055] Specifically, the processing equipment is also configured as follows:

[0056] When the real-time form is fully deployed, the first operating curve Z1 is used as the overturning judgment curve.

[0057] When the real-time state is fully recovered, the second operating curve Z2 is used as the overturning judgment curve;

[0058] The stable region defined by the second operating curve Z2 is larger than the stable region defined by the first operating curve Z1.

[0059] like Figure 4 As shown in the figure, the solid line represents the first operating curve Z1, with region I being the stable zone and regions II and III being the rollover zones. The dashed line represents the second operating curve Z2, with regions I and II being the stable zones and region III being the rollover zone. Compared to existing technologies that only use the first operating curve Z1 as the rollover determination curve, this application selects the corresponding operating curve as the rollover determination curve based on the real-time configuration. This allows the deployment platform to obtain the operating range of region II when fully retracted, thus more efficiently utilizing the load-bearing capacity of the deployment platform and fully leveraging the stability performance of the entire vehicle.

[0060] Specifically, the platform detection device includes: a limit switch 3, which is set between the main platform 1 of the retractable platform and the retractable secondary platform 2, and is configured to switch its on / off state accordingly when switching between the fully extended form and the fully retracted form.

[0061] Those skilled in the art will understand that the platform detection device is not limited to the aforementioned limit switch 3, but can also be a position sensor. Other structural forms capable of detecting the real-time shape of the deployment and retraction platform should also fall within the scope of protection of this application.

[0062] Specifically, the control system also includes a horizontal distance detection device and a vertical distance detection device for respectively detecting the horizontal and vertical distances of the boom tip of the aerial work platform relative to a preset tilting line C; the processing device communicates with the horizontal distance detection device and the vertical distance detection device, and is further configured as follows:

[0063] If at least one of the horizontal and vertical spacings is located in the overturning zone defined by the first operating curve Z1, an overturning warning trigger signal is issued and / or the unfolding platform is prohibited from performing unfolding actions.

[0064] In this application, the control system senses the position of the boom tip using horizontal and vertical spacing detection devices. The horizontal and vertical spacing together form the real-time position coordinates of the boom tip. When the retractable platform is in its fully extended state, the processing equipment selects the first operating curve Z1 as the rollover judgment curve. If the processing equipment determines that the real-time position coordinates of the boom tip are within the rollover zone, the entire vehicle is at risk of rollover, requiring a rollover warning to be issued, and the retractable platform to be prohibited from performing any deployment actions.

[0065] Furthermore, the control system also includes a constant-lock mechanism for locking the real-time configuration and a deployment trigger mechanism for generating a deployment trigger signal; the processing device communicates with the constant-lock mechanism and the deployment trigger mechanism, and is further configured to:

[0066] Upon receiving the deployment trigger signal, determine whether both the horizontal and vertical spacing are within the stable region defined by the first operating curve Z1;

[0067] When both the horizontal and vertical spacing are within the stable zone defined by the first operating curve Z1, the constant lock mechanism is unlocked so that the unfolding platform can perform the unfolding action.

[0068] In this application, after the user initiates the deployment and retrieval platform to perform the deployment action through the deployment trigger mechanism, the processing equipment selects the first operating curve Z1 as the overturning judgment curve. Only when the real-time position coordinates of the boom tip are in the stable zone will the processing equipment control the normally locked mechanism to unlock and control the deployment and retrieval platform to perform the deployment action; at the same time, the normally locked mechanism is in a locked state by default, physically preventing erroneous operation of the deployment action; thereby ensuring that the deployment and retrieval platform performs the deployment action under safe conditions and reducing the risk of overturning.

[0069] Specifically, the control system also includes an alarm device for issuing tilt warning signals, and horizontal and vertical distance detection devices for detecting the horizontal and vertical distances of the boom tip of the aerial work platform relative to a preset tilt line C, respectively; the processing device communicates with the horizontal distance detection device, the vertical distance detection device, and the alarm device, and is further configured as follows:

[0070] If at least one of the horizontal and vertical spacings is located within the overturning zone defined by the overturning determination curve, an overturning warning trigger signal is issued to trigger the alarm device to issue an overturning warning signal.

[0071] In this application, the processing equipment selects the corresponding operating curve as the rollover judgment curve based on the real-time situation, and the horizontal and vertical spacing constitutes the real-time position coordinates of the boom tip. If the processing equipment determines that the real-time position coordinates of the boom tip are located in the rollover zone, then the entire vehicle is at risk of rollover, and the alarm device can issue a rollover warning.

[0072] In some embodiments, the retractable platform includes a main platform 1 and two secondary platforms 2, which extend and retract from both ends of the main platform 1 via telescopic movement. Two limit switches 3 are located on the secondary platforms 2, and their active contacts contact the main platform 1 after the retractable platform is fully extended. The normally locked mechanism is an electronic lock 4, with two electronic locks 4 located between the main platform 1 and the secondary platforms 2, used to lock the relative positions of the secondary platforms 2 and the main platform 1. The extension trigger mechanism is an unlock button 5 located on the main platform 1, which the user presses to request the processing device to unlock the electronic locks 4. The alarm device is an alarm 6 with audible and visual alerts, located on the main platform 1.

[0073] A control method for aerial work machinery, comprising:

[0074] Detect the real-time status of the extension and retraction platform of aerial work machinery;

[0075] Different operating curves are selected as the overturning judgment curves for aerial work machinery based on different real-time conditions.

[0076] Detect the horizontal and vertical distances between the top of the boom of the aerial work platform and the preset tilting line C;

[0077] If at least one of the horizontal and vertical spacing is located in the rollover zone defined by the rollover determination curve, a rollover warning trigger signal is issued.

[0078] Specifically, the selection of the rollover judgment curve includes:

[0079] When the real-time form is fully deployed, the first operating curve Z1 is used as the overturning judgment curve.

[0080] When the real-time state is fully recovered, the second operating curve Z2 is used as the overturning judgment curve;

[0081] The stable region defined by the second operating curve Z2 is larger than the stable region defined by the first operating curve Z1.

[0082] Specifically, when the first operating curve Z1 is selected as the overturning judgment curve, if at least one of the horizontal spacing and the vertical spacing is located in the overturning zone defined by the first operating curve Z1, the deployment platform is prohibited from performing the deployment action and / or issuing an overturning warning trigger signal.

[0083] like Figure 7 As shown, in some embodiments, the control method for determining the vehicle's rollover resistance is as follows: First, limit switch 3 is used to detect whether the retractable platform is deployed, and the result is sent to the processing equipment. When deployment is detected, the processing equipment selects the first operating curve Z1 as the rollover determination curve; otherwise, it selects the second operating curve Z2 as the rollover determination curve. Then, the horizontal distance detection device and the vertical distance detection device on the boom measure the horizontal length and vertical height of the boom top from the preset rollover line C, respectively, and send the results to the processing equipment. When the horizontal length and vertical height are determined to be within the rollover zone of the rollover determination curve, the processing equipment determines that there is a rollover risk, triggers alarm 6, and does not respond to the operation; otherwise, it is determined to be safe and maintains normal operation.

[0084] like Figure 8 As shown, in some embodiments, the control method for deploying the retrieval platform is as follows: the operator presses the unlock button 5 to request the processing equipment to unlock the electronic lock 4. The horizontal distance detection device and the vertical distance detection device on the boom measure the horizontal length and vertical height of the top of the boom from the preset tipping line C, respectively, and transmit the results to the processing equipment. The processing equipment selects the first operating curve Z1 as the tipping judgment curve. When the horizontal length and vertical height are determined to be within the tipping zone of the tipping judgment curve, the processing equipment determines that there is a risk of tipping, triggers the alarm 6, does not respond to the operation, and prompts the operator that deployment is not currently allowed; otherwise, the electronic lock 4 is unlocked, and the retrieval platform is controlled to perform the deployment action.

[0085] This application detects the real-time state of the deployment and retrieval platform and selects either a first operating curve Z1 or a second operating curve Z2 as the overturning judgment curve, thereby making more efficient use of the platform's load-bearing capacity and operating range. This application also ensures operational safety by manually unlocking the platform and determining whether it can be deployed based on the first operating curve Z1.
