During the operation of the aerial work platform, the boom drives the platform to move. During this process, the height of the platform is monitored in real time. When the height H of the platform is greater than a preset height h, the aerial work platform is determined to be in a dangerous mode. At this time, if the aerial work platform passes over a pothole road surface, the aerial work platform is at risk of tipping over.

Therefore, the pothole tilting device is controlled to be in a folded state, and the walking mechanism is switched to a high-speed mode, so that the aerial work platform can move quickly. By determining the height of the platform and then the state of the pothole tilting device, the overturning of the aerial work platform is avoided, the personal safety of the operators is improved, and damage to the aerial work platform is avoided.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0047] like Figures 1 to 3As shown, this embodiment provides an aerial work platform, including a walking mechanism 1, a boom 2, a platform 3 and an anti-pothole tilting device 4, one end of the boom 2 is pivotally connected to the walking mechanism 1, and the other end of the boom 2 is pivotally connected to the platform 3, and the anti-pothole tilting device 4 is arranged on the chassis of the walking mechanism 1, and the anti-pothole tilting device 4 includes a driving assembly and two support plates 45, and the two support plates 45 are pivotally connected to both sides of the chassis along the vehicle width direction, and the driving assembly drives the two support plates 45 to swing synchronously so that the two support plates 45 have an unfolded state and a folded state. In the unfolded state, the distance between the support plate 45 and the ground is less than the distance between the chassis and the ground, and in the folded state, the distance between the support plate 45 and the ground is greater than or equal to the distance between the chassis and the ground. When the aerial work platform is working, the walking mechanism 1 is used to drive the aerial work platform to move in the horizontal plane, and the arm 2 is used to adjust the height of the platform 3 in the vertical direction. When the vehicle is driving on a pothole road and there are workers working on the platform 3, in order to prevent the aerial work platform from tipping over, the support plates 45 of the anti-pothole tilting device 4 are switched to the unfolded state. At this time, the two support plates 45 reduce the ground clearance of the aerial work platform. When the wheels of the walking mechanism 1 fall into a pothole, the support plates 45 are supported on the ground, which can effectively reduce the overall tilt angle of the aerial work platform to avoid the tipping of the aerial work platform or reduce the danger of the workers. When the aerial work platform needs to move horizontally quickly, in order to prevent the walking mechanism 1 from bottoming out, the two support plates 45 are switched to the folded state to increase the ground clearance of the walking mechanism 1 and improve the passability of the aerial work platform.

[0048] Optionally, the driving assembly includes a telescopic member 41, two inner swing arms 42, two outer swing arms 43 and two connecting rods 44. The telescopic member 41 is arranged on the symmetry line of the two support plates 45 along the vehicle width direction, and the telescopic end of the telescopic member 41 is telescopic along the vehicle height direction. One end of the two inner swing arms 42 is pivoted to the telescopic end of the telescopic member 41, and the other ends of the two inner swing arms 42 are respectively pivoted to one end of the two outer swing arms 43, and the middle parts of the two outer swing arms 43 are respectively pivoted to the chassis, and the other ends of the two outer swing arms 43 are respectively pivoted to one end of the two connecting rods 44, and the other ends of the two connecting rods 44 are respectively pivoted to the two support plates 45, and the pivoting position of the support plate 45 and the chassis is spaced apart from the pivoting position of the support plate 45 and the corresponding connecting rod 44. In this embodiment, the telescopic end of the telescopic member 41 drives one end of the two inner swing arms 42 to move along the vehicle height direction. At the same time, the other ends of the two inner swing arms 42 act on one end of the two outer swing arms 43 respectively, thereby causing the two outer swing arms 43 to rotate around the pivot shafts on the chassis respectively. The other ends of the two outer swing arms 43 act on the two connecting rods 44. Since the pivot position between the support plate 45 and the chassis and the pivot position between the support plate 45 and the corresponding connecting rod 44 are arranged at intervals, the support plate 45 is swung relative to the chassis to switch the support plate 45 between the unfolded position and the folded position.

[0049] Specifically, the telescopic member 41 is arranged on the symmetry line of the two support plates 45 along the vehicle width direction, and this arrangement can make the two support plates 45 swing synchronously.

[0050] Optionally, the outer swing link 43 is bent into an L shape, and the bending part of the outer swing link 43 is pivoted to the chassis. In this embodiment, the outer swing link 43 includes a first rod 431 and a second rod 432 that are fixed to each other and are L-shaped, and the first rod 431 is pivoted to the other end of the corresponding inner swing link 42. When the telescopic member 41 drives one end of the inner swing link 42 to swing along the vehicle height direction, the other end of the inner swing link 42 drives the first rod 431 to swing, thereby driving the second rod 432 to swing, and the swing of the second rod 432 drives the corresponding connecting rod 44 to swing accordingly.

[0051] Optionally, a protrusion 433 is convexly provided on the peripheral wall of the bend of the outer swing rod 43; the anti-pothole tilting device 4 also includes two travel switches 46, which are respectively fixed to the chassis and respectively opposite to the two protrusions 433, and the contacts of the travel switches 46 abut against the corresponding protrusions 433. In this embodiment, when the outer swing rod 43 swings relative to the chassis, the protrusion 433 drives the contact to move, and the travel switch 46 can determine the swing angle of the support plate 45 by judging the movement of the protrusion 433, and can switch the support plate 45 between the unfolded state and the folded state by controlling the working state of the telescopic member 41. Specifically, the travel switch 46 is a prior art and will not be described in detail here.

[0052] Optionally, the chassis is provided with a limit slide groove 11 along the vehicle height direction, and the telescopic end of the telescopic member 41 is slidably provided in the limit slide groove 11. In this embodiment, when the telescopic end of the telescopic member 41 is subjected to a force along the vehicle width direction, the groove wall of the limit slide groove 11 can limit the telescopic end of the telescopic member 41 from swinging along the vehicle width direction, and this arrangement improves the synchronization of the two support plates 45.

[0053] Optionally, the telescopic member 41 is a cylinder.

[0054] like Figure 4 As shown, this embodiment also provides an anti-pothole tilt control method for an aerial work platform, which is applied to the aerial work platform and includes:

[0055] S10: Monitor the height H of the platform 3 of the aerial work platform.

[0056] In this step, the height H of the platform 3 from the ground can be measured in real time by a laser rangefinder.

[0057] S20: If H>h, execute S30; otherwise, execute S40.

[0058] In this step, by monitoring the height H of the platform 3 of the aerial work platform, it is possible to determine whether the aerial work platform is in a safe mode or a dangerous mode.

[0059] S30: Controlling the anti-pothole tilting device 4 to be in the deployed state.

[0060] S30 specifically includes:

[0061] S301: Determine whether the anti-pothole tilting device 4 is in the deployed state, if so, execute S31, if not, execute S302.

[0062] In this step, since H>h, there are workers working on the platform 3 at this time. In order to ensure the safety of the workers, it is necessary to control the anti-pothole tilting device 4 to the deployed state. If the anti-pothole tilting device 4 is in the deployed state, execute S31; if the anti-pothole tilting device 4 is not in the deployed state, execute S302.

[0063] S302: Determine whether the platform 3 of the aerial work platform is in an ascending state, if so, execute S304, if not, execute S10.

[0064] In this step, if the platform 3 is in an ascending state, it indicates that the risk factor of the staff is gradually increasing, so S303 is executed. If the platform 3 is in a descending state, it indicates that the risk factor of the staff is gradually decreasing, so S10 is executed.

[0065] Optionally, in step S301, when it is determined that the anti-pothole and tilting device 4 is not in the deployed state, step S302 is executed and an alarm is issued; in this step, the aerial work platform is provided with an audible and visual alarm, and at this time, the audible and visual alarm issues an alarm to remind the staff that the anti-pothole and tilting device 4 is not in the deployed state.

[0066] S303: The traveling mechanism 1 switches to the parking mode, and the movement of the boom 2 is not restricted.

[0067] In this step, the traveling mechanism 1 is switched to the parking mode, thereby preventing the wheels of the traveling mechanism 1 from falling into a pothole.

[0068] S304: Control the anti-pothole tilt device 4 to deploy.

[0069] Optionally, in step S304, after the anti-pothole tilting device 4 is controlled to be deployed, the alarm is turned off.

[0070] S31: The walking mechanism 1 switches to the low-speed mode, the movement of the arm 2 is not restricted, and the process returns to S10.

[0071] In this step, when the anti-pothole tilting device 4 is unfolded, the movement of the arm 2 is not restricted, and the height H of the platform 3 can be adjusted. At the same time, the walking mechanism 1 switches to the low-speed mode, thereby being able to adjust the position of the platform 3 in the horizontal plane.

[0072] S40: Controlling the anti-pothole tilting device 4 to be in a folded state.

[0073] S40 specifically includes:

[0074] S401: Determine whether the anti-pothole tilting device 4 is in a folded state, if so, execute S41, if not, execute S402.

[0075] In this step, since H≤h, the aerial work platform will not cause harm to the workers even if it encounters a pothole. If the anti-pothole tilting device 4 is in a folded state, S41 is executed; if the anti-pothole tilting device 4 is in an unfolded state, S402 is executed.

[0076] S402: Determine whether the platform 3 of the aerial work platform is in a descending state, if so, execute S403, if not, execute S10.

[0077] In this step, if the platform 3 is in an ascending state, it indicates that the risk factor of the staff is gradually increasing, so S10 is executed. If the platform 3 is in a descending state, it indicates that the risk factor of the staff is gradually decreasing, so S403 is executed.

[0078] Optionally, in step S401, when it is determined that the anti-pothole and tilting device 4 is not in a folded state, step S402 is executed and an alarm is issued; in this step, the sound and light alarm issues an alarm to remind the staff that the anti-pothole and tilting device 4 is in an unfolded state, and not to switch the walking mechanism 1 to high-speed mode to prevent the aerial work platform from bottoming out.

[0079] S403: The traveling mechanism 1 switches to the low-speed mode, and the movement of the boom 2 is not restricted.

[0080] In this step, in order to prevent the aerial work platform from bottoming out, the traveling mechanism 1 is switched to a low-speed mode.

[0081] S404: Control the anti-pothole tilting device 4 to fold.

[0082] Optionally, in step S404, after controlling the anti-pothole tilting device 4 to be folded, the alarm is turned off.

[0083] S41: The walking mechanism 1 switches to high-speed mode, the movement of the arm 2 is not restricted, and the process returns to S10.

[0084] In this step, when the anti-pothole tilting device 4 is in the folded state, the ground clearance of the chassis increases, so the walking mechanism 1 can be switched to the high-speed mode.

[0085] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
