Description

Technical Field

[0001] This utility model relates to the field of work platform leveling technology, and in particular to a multi-directional leveling work platform for aerial work vehicles. Background Technology

[0002] Operators of existing aerial work platforms operate machines at heights by standing inside the platform. Therefore, keeping the platform level is crucial for operators. A tilted platform not only affects the operator's work efficiency and causes discomfort, but in severe cases, it can also cause the operator to fall, posing a safety risk.

[0003] The leveling methods for aerial work platforms are mostly hydraulic or electric. By moving hydraulic cylinders or motors, the platform is adjusted to rotate in a plane, thereby achieving the leveling effect. However, this method can only achieve adjustment in one direction, front and back. When the vehicle is parked on a complex slope, it cannot guarantee that it is level in all directions, causing strong discomfort to the operator and making it impossible to perform level work.

[0004] Therefore, how to achieve multi-directional leveling of the work platform is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0045] The purpose of this utility model is to provide a multi-directional leveling platform for aerial work vehicles and a multi-directional leveling method, which can realize the leveling of the platform in multiple directions.

[0046] It should be noted that in this embodiment, the X direction in the attached figure is defined as the first direction, the Y direction as the second direction, and the Z direction as the third direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0047] To achieve the above objectives, the present invention provides the following technical solution:

[0048] Please see Figures 1 to 4 This embodiment provides a multi-directional leveling platform for an aerial work platform, installed at the end of the main boom 01 of the aerial work platform, including: a connecting frame 100 hinged to the main boom 01; a first leveling drive device 200 connected between the main boom 01 and the connecting frame 100, used to drive the connecting frame 100 to rotate around a first axis 110, the first axis 110 being parallel to a first direction; a bracket 300 connected to the connecting frame 100; a working platform 400 rotatably mounted on the bracket 300; and a second adjustment drive device 500 connected between the bracket 300 and the working platform 400, used to drive the working platform 400 to rotate around a second axis 410, the second axis 410 being parallel to a second direction; wherein, the first direction and the second direction are perpendicular.

[0049] Specifically, the multi-directional leveling platform provided in this embodiment is installed at the end of the main boom 01 of the aerial work platform. First, the connecting frame 100 is rotatably connected to the end of the main boom 01 via the first shaft 110. At the same time, the first leveling drive device 200 is disposed between the main boom 01 and the connecting frame 100. The first leveling drive device 200 can drive the connecting frame 100 to rotate around the first shaft 110, which causes other devices connected to the connecting frame 100 to rotate. The first shaft 110 is parallel to the first direction, that is, the rotation direction of the connecting frame 100 is to tilt down and tilt up in the vertical direction, so that other devices installed on the connecting frame 100 can be leveled in the vertical direction (i.e., rotated around the X-axis).

[0050] In this embodiment, the first leveling drive device 200 is preferably a hydraulic cylinder, one end of which is hinged to the lower side of the main arm 01 and the other end of which is hinged to the connecting frame 100. The connecting frame 100 can rotate around the first axis 110 by the extension and retraction of the first leveling drive device 200. The remaining components are installed on the side of the connecting frame 100 away from the main arm 01.

[0051] Furthermore, in this embodiment, the work platform 400 is a structure with a fence as in the prior art, which will not be described in detail here.

[0052] Furthermore, the work platform 400 is connected to the connecting frame 100 via the bracket 300, that is, the bracket 300 is mounted on the connecting frame 100, and the work platform 400 is mounted on the bracket 300. At the same time, the work platform 400 is mounted on the bracket 300 via the second shaft 410, and can rotate around the second shaft 410 under the drive of the second adjustment drive device 500. In this embodiment, the bracket 300 serves to support the work platform 400, and the work platform 400 can rotate around the second shaft 410, which is parallel to the second direction. It can be understood that leveling a plane usually requires independent adjustment in two directions. After the work platform 400 has been leveled in one direction (X direction) above, it only needs to be adjusted in the second direction, that is, the Y direction. The second adjustment drive device 500 is also preferably a hydraulic cylinder, one end of which is hinged to the bracket 300, and the other end of which is hinged to the work platform 400. The extension and retraction of the second leveling drive device can make the work platform 400 rotate around the second shaft 410.

[0053] In summary, the working platform 400 can be leveled from different directions by driving at least one of the first leveling drive device 200 and the second adjustment drive device 500. That is, by the coordinated automatic control of two degrees of freedom, rotation around the X-axis (first direction axis) and rotation around the Y-axis (second direction axis), the traditional single-degree-of-freedom leveling is extended to spatial attitude control, which effectively solves the problem of vehicles being unable to be leveled on complex slopes.

[0054] In one possible implementation, an angle sensor 600 is provided on the work platform 400, which is used to detect the tilt angle of the work platform 400 in a first direction and a second direction.

[0055] Understandably, in order to detect the status of the work platform 400 in real time and determine whether it is level, in this embodiment, an angle sensor 600 is installed on the work platform 400, which can detect the angle of the work platform 400 deviating from the horizontal plane, thereby facilitating subsequent adjustments to the work platform 400.

[0056] In one possible implementation, a valve block unit 700 is included. The valve block unit 700 is disposed on the bracket 300. The valve block unit 700 is connected to the first leveling drive device 200 and the second adjustment drive device 500 respectively, and is used to control the operation of the first leveling drive device 200 and the second adjustment drive device 500.

[0057] In this embodiment, both the first leveling drive device 200 and the second adjustment drive device 500 are preferably hydraulic cylinders. Therefore, a valve block unit 700 is provided to drive the two devices. It is fixedly installed on the bracket 300 and is connected to both the first leveling drive device 200 and the second adjustment drive device 500 by two oil pipes, one inlet pipe and one return pipe. When it receives an action command or signal, it controls the action of the first leveling drive device 200 and the second adjustment drive device 500 by controlling the oil inlet and outlet.

[0058] Furthermore, a control unit 800 is included, which is connected to the angle sensor 600 and the valve block unit 700 respectively. The control unit 800 is configured to control at least one of the first leveling drive device 200 and the second adjustment drive device 500 via the valve block unit 700 in response to the tilt angle detected by the angle sensor 600, so as to drive the first axis 110 and / or the second axis 410 of the work platform 400 to rotate so that the work platform 400 remains level.

[0059] Understandably, the leveling action of the work platform 400 can be manually controlled by the valve block unit 700 when the angle sensor 600 detects that it deviates from the horizontal plane. However, in order to make the leveling action of the work platform 400 faster, more timely and more accurate, this embodiment is provided with a control unit 800, which is directly connected to the angle sensor 600. It can directly receive the angle signal detected by the angle sensor 600, determine the angle of deviation, and calculate the angle that the first leveling drive device 200 and the second adjustment drive device 500 need to adjust. Then, it controls the valve block unit 700 to enter and exit the corresponding volume of hydraulic oil to complete the leveling action.

[0060] It should be noted that it can not only control the first leveling drive device 200 and the second adjustment drive device 500 to operate simultaneously, but also control the operation of one of them individually, and the two do not affect each other when they are operating.

[0061] In one possible implementation, a swing drive device 900 is also included, which is disposed between the connecting frame 100 and the bracket 300. The swing drive device 900 is connected to the valve block unit 700. The swing drive device 900 drives the bracket 300 to rotate around the third axis 310 through the valve block unit 700. The third axis 310 is parallel to the third direction. The third direction is perpendicular to the first direction and the second direction, respectively.

[0062] Furthermore, in order to enable the work platform 400 to rotate arbitrarily in three-dimensional space within the safety limit, in this embodiment, the bracket 300 is connected to the connecting frame 100 through a swing drive device 900. In this embodiment, the swing drive device 900 is preferably a swing cylinder. The swing cylinder is a structure in the prior art, and will not be described in detail here. The swing drive device 900 includes an outer cylinder body and an inner ring rotatably connected inside it. The cylinder body of the swing drive device 900 is fixedly installed on the connecting frame 100, while the bracket 300 is fixedly connected to the inner ring. The bracket 300 rotates together with the inner ring.

[0063] It should be noted that the rotation axis of the swing drive device 900 is vertical, which is the third direction in this article. It can only make the bracket 300 swing in the horizontal direction, but cannot interfere with the leveling of the work platform 400.

[0064] In one possible implementation, the first leveling drive device 200, the second adjustment drive device 500, and the swing drive device 900 are specifically one of a hydraulic cylinder, an electric cylinder, and a pneumatic cylinder.

[0065] Understandably, the first leveling drive device 200, the second adjusting drive device 500, and the swing drive device 900 are power source components, and they can be selected from hydraulic cylinders, electric cylinders, and pneumatic cylinders as needed. Of course, when an electric cylinder or a pneumatic cylinder is selected, the valve block unit 700 should also select components that can control its action according to the actual situation.

[0066] In one possible implementation, the bracket 300 has an L-shaped structure, which includes a connecting part 320 that is rotatably connected to the connecting frame 100 and a supporting part 330 for supporting the work platform 400. The upper side of the supporting part 330 is provided with a mounting seat 331 for rotatably connecting to the work platform 400.

[0067] Specifically, such as Figure 3 As shown, the bracket 300 has an overall L-shaped structure. Its vertical part is the connecting part 320, and its horizontal part is the bearing part 330. The back of the connecting part 320 is connected to the swing drive device 900. The upper side of the bearing part 330 is provided with a mounting seat 331 along the second direction. Specifically, the mounting seat 331 is a pair of parallel connecting ears. The middle of the connecting ears is provided with a through hole along the second direction. The through hole is used to install the second shaft 410.

[0068] Of course, the shape of the bracket 300 is preferred but not limited to an L-shaped structure. The shape of the bracket 300 can be selected according to actual needs, as long as it can support the work platform 400 and rotate to connect with the connecting frame 100. This article does not make specific limitations here.

[0069] Furthermore, a connecting protrusion 420 is provided on the lower side of the work platform 400, and the connecting protrusion 420 is hinged to the mounting base 331 via the second shaft 410.

[0070] Correspondingly, a connecting protrusion 420 is provided on the lower side of the work platform 400. The connecting protrusion 420 can be installed between the two connecting ears of the mounting base 331. The connecting protrusion 420 is provided with a through hole, which will be aligned with the through hole on the mounting base 331. The second shaft 410 connects the work platform 400 and the mounting base 331, so that the two can rotate relative to each other, so as to facilitate the leveling of the work platform 400.

[0071] Furthermore, in this embodiment, the connecting protrusion 420 is welded to the lower side of the work platform 400, which enhances the overall structural strength of the work platform 400 and thus increases its service life.

[0072] Furthermore, both the bracket 300 and the connecting frame 100 are integral structures. Understandably, this design increases the structural strength of both, preventing accidents from happening to the work platform 400 during use. This not only increases its service life but also improves its safety during use.

[0073] This article also provides a multi-directional leveling method, applied to the aforementioned multi-directional leveling platform for aerial work vehicles, as detailed below. Figure 4 As shown, the multi-directional leveling platform of the aerial work vehicle also includes a control unit 800, a valve block unit 700, and an angle sensor 600. The control unit 800 is connected to the valve block unit 700 and the angle sensor 600 via signals. The multi-directional leveling method includes:

[0074] The tilt angle of the work platform 400 in the first and second directions is detected by the angle sensor 600.

[0075] The tilt angle is received via control unit 800;

[0076] The control unit 800 determines whether the work platform 400 is deviating from the horizontal based on the tilt angle.

[0077] When the control unit 800 determines that the working platform 400 is deviating from the horizontal, it sends a control signal to the valve block unit 700.

[0078] The valve block unit 700 controls the first leveling drive device 200 and / or the second adjustment drive device 500 to drive the work platform 400 to rotate around the first axis 110 and / or the second axis 410 until the leveling of the work platform 400 is completed.

[0079] Furthermore, the multi-directional leveling work platform of the aerial work vehicle also includes a swing drive device 900, and the swing drive device 900 is manually controlled by the control unit 800 to drive the bracket 300 to rotate around the third axis 310, thereby adjusting the orientation of the work platform 400.

[0080] In summary, in the multi-directional leveling work platform of the aerial work vehicle provided in this application, the main boom 01 is connected to the connecting frame 100 and the first leveling drive device 200. The first leveling drive device 200 can adjust the connecting frame 100 to rotate around the X-axis direction (i.e., the first direction). The swing drive device 900 is fixed to the connecting frame 100. The bracket 300 is connected to the swing drive device 900. The inner ring gear of the swing drive device 900 is fixed to the bracket 300 by bolts, and the outer ring is fixed to the connecting frame 100. Oil is supplied to the swing drive device 900 through the valve block unit 700, which can drive the bracket. The bracket 300 rotates around the Z-axis (i.e., the third direction); the valve block unit 700 is fixed on the bracket 300; the angle sensor 600 is fixed on the working platform 400, keeping it parallel to the bottom plane of the working platform 400; the working platform 400 is connected to the bracket 300 through the shaft hole of the connecting protrusion 420 on its lower side, and the second shaft 410 connects the bracket 300 and the working platform 400; one end of the second adjustment drive device 500 is hinged to the working platform 400, and the other end is hinged to the bracket 300, and the adjusting cylinder can drive the working platform 400 to rotate around the Y-axis (i.e., the second direction).

[0081] The multi-directional leveling method applied to the aforementioned mechanism is as follows: When the aerial work platform travels on non-level ground or when the work platform 400 is no longer level due to boom movement, the angle sensor 600 fixed on the work platform 400 determines the angle by which the work platform 400 deviates from the horizontal plane. This angle sensor 600 should be a dual-axis angle sensor 600, capable of monitoring angles in two directions. When the angle sensor 600 detects an angle deviation from a preset angle range, the signal is processed by the controller unit on the entire machine and sent to the valve block unit 700. The valve block unit 700 (which is connected to the swing drive device 900) can then be controlled. The first leveling drive device 200 and the second adjustment drive device 500 are each connected by two oil pipes (one inlet pipe and one return pipe). The first leveling drive device 200 and / or the second adjustment drive device 500 are driven to make the working platform 400 rotate around the X-axis (i.e., the first direction) or the Y-axis (i.e., the second direction), thereby ensuring that the working platform 400 remains horizontal. At the same time, the controller unit can directly and manually output a signal to the valve block unit 700 to drive the swing drive device 900 to rotate around the Z-axis (i.e., the third direction), thereby realizing the arbitrary rotation of the working platform 400 in three-dimensional space within the safe limit range, and realizing the multi-directional leveling of the working platform 400.

[0082] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0083] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0084] The embodiments provided by this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
