Description

Technical Field

[0001] This invention relates to the field of aerial work platform technology, specifically to an integrated biomimetic elephant trunk multi-joint boom assembly and an intelligent aerial work platform. Background Technology

[0002] Aerial work platforms are specialized engineering vehicles used to transport personnel and equipment to designated heights for specific operations. They are widely used in municipal maintenance, building construction, infrastructure development, and fire rescue. With accelerating urbanization and expanding infrastructure construction, the market demand for aerial work platforms continues to grow. The boom mechanism, as a crucial functional component of aerial work platforms, directly impacts the working space range and operational flexibility. Furthermore, tilting of the work platform can lead to decreased operational stability and affect operational accuracy.

[0003] Aerial work platforms typically consist of a chassis, a turntable, a main boom, and a work platform. The turntable is mounted on the chassis, with the rear end of the main boom connected to the turntable and the front end connected to the work platform. The turntable rotates relative to the chassis, and after the main boom is deployed and raised, it moves the work platform to the designated aerial work area. Aerial work platforms equipped with a boom mechanism connect the main boom and the work platform to enhance operational flexibility.

[0004] However, existing boom mechanisms have limited working range and degrees of freedom, with motion freedom mainly concentrated on boom folding and amplitude adjustment, making it difficult to cover complex spatial trajectories and limiting operational flexibility and spatial accessibility. Traditional leveling systems have low real-time leveling accuracy during worktable movement. While some systems use multi-stage transmissions to expand the leveling range, their complex structure, heavy weight, and high cost limit their application in high-stability operation scenarios.

[0005] Therefore, there is an urgent need for an aerial work platform with multi-degree-of-freedom motion capability and high-precision real-time leveling to improve the operational flexibility, stability and overall performance of aerial work platforms. Summary of the Invention

[0006] The purpose of this invention is to provide an integrated biomimetic elephant trunk multi-joint boom assembly and an intelligent aerial work platform, which enables flexible and precise adjustment of the work platform with a large number of degrees of freedom, thereby improving the working range, flexibility and precision of the work platform.

[0009] Preferably, the support frame includes a main frame and side frames disposed on opposite sides of the main frame; Between two adjacent support frames, the front end of one main frame is hinged to the rear end of the other main frame, and the two ends of the telescopic cylinder are respectively connected to the side frames on the same side of the two adjacent support frames.

[0010] Preferably, it also includes an angle sensor and a controller; An angle sensor is installed on the support frame. The angle sensor is used to monitor the swing angle between two adjacent support frames. The controller is connected to the control end of the swing drive mechanism and the angle sensor respectively.

[0011] Preferably, it also includes a support base, with the lower end of the support frame at the end connected to the support base, a working platform provided on the support base, and a plurality of levelers provided between the support base and the working platform, the levelers being used to adjust the levelness of the working platform.

[0012] Preferably, the leveler includes a base, a first track support, a second track support, a support member, a leveling seat, and a leveling drive mechanism; The base is mounted on the support base; The first track support can swing relative to the base in the left and right directions, and the first track support is provided with a first arc-shaped track that extends in the front and rear directions.

The second track support is provided with a second arc-shaped and hollowed-out second track that extends in the left and right directions. The lower end of the support passes through the second track, and the support slides into the second track. The lower end of the support slides into the first track. A leveling seat is provided at the upper end of the support, and the leveling seat is connected to the work platform. The leveling drive mechanism drives the first track support to swing relative to the base in the left and right directions, and the leveling drive mechanism drives the second track support to swing relative to the base in the front and back directions.

[0013] Preferably, four levelers are provided, with one leveler arranged at each of the four corners of the support base and the working platform; The two ends of the support member can extend and retract relative to each other.

[0014] Preferably, the leveler is a single unit, positioned at the midpoint between the support base and the work platform.

[0015] The present invention also provides an intelligent aerial work platform, including a chassis and a turntable, and the aforementioned integrated bionic elephant trunk multi-joint boom assembly, wherein the rear end of the main boom is connected to the turntable.

[0016] Preferably, the main boom includes several telescopic booms arranged in a nested manner, with adjacent telescopic booms capable of relative extension and retraction.

[0017] The integrated biomimetic elephant trunk multi-joint boom assembly and intelligent aerial work vehicle of the present invention achieve the following significant technical effects by combining the biomimetic elephant trunk multi-degree-of-freedom flexible motion principle with high-precision real-time leveling technology: 1. This invention significantly improves the operational flexibility and spatial accessibility of aerial work platforms. The boom employs a multi-segment support frame connected sequentially by hinges, and features a structure that alternately swings around a first and second mutually perpendicular axis. Combined with the coordinated control of the swing drive mechanism, the boom can simulate the multi-degree-of-freedom bending motion of an elephant's trunk, enabling flexible and precise positional adjustments of the work platform in three-dimensional space. This design overcomes the limitations of traditional boom mechanisms, which can only achieve folding and variable angle adjustments, significantly expanding the operational range. It can cover more complex spatial trajectories and adapt to various aerial work scenarios, especially demonstrating excellent obstacle avoidance capabilities when navigating obstacles such as pipelines, eaves, and trees.

[0018] 2. This invention ensures high stability and levelness of the work platform under all working conditions. The innovative design of the leveler, through the base, the swingable first and second track supports, and the slidingly fitted support components and leveling seat, achieves real-time, high-precision leveling of the work platform during the multi-degree-of-freedom movement of the boom. Whether using levelers arranged at the four corners or a single leveler arranged in the center, it effectively compensates for platform tilt caused by changes in boom posture, ensuring the work platform remains level at all times. This greatly improves operational stability and safety, and guarantees the precision of high-altitude operations.

[0019] 3. This invention integrates the boom assembly onto an intelligent aerial work platform. By combining the telescopic movement of the main boom, the rotation of the turntable, and the luffing of the lifting hydraulic cylinder, it works in conjunction with the bionic flying boom and leveler, enabling the vehicle to possess a wide range, high precision, and intelligent operating capabilities. This meets the increasing demands for flexibility and efficiency in modern urban maintenance, installation, firefighting, and other high-altitude operations, thereby enhancing the product's core competitiveness.

They are used only for the convenience of describing this invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] Example 1: Please refer to Figures 1 to 12 As shown in the embodiment of the present invention, an integrated biomimetic elephant trunk multi-joint boom assembly and an intelligent aerial work platform are provided.

[0024] An integrated biomimetic elephant trunk multi-joint flying boom assembly includes a main boom 1, a flying boom 2, a leveler 3, and a work platform 4.

[0025] The main boom 1 includes several telescopic booms 11 arranged in a nested manner, and adjacent telescopic booms 11 can extend and retract relative to each other.

[0026] The boom 2 includes multiple support frames 21 that are hinged to each other at the front and rear by hinges 23. Several pairs of adjacent support frames 21 swing relative to each other around a first axis 51, and several pairs of adjacent support frames 21 swing relative to each other around a second axis 52. The first axis and the second axis 52 are arranged perpendicularly to each other. Adjacent support frames 21 are driven to swing relative to each other by a swing drive mechanism.

[0027] The upper end of the support frame 21 at the front end is connected to the front end of the main boom 1, and the lower end of the support frame 21 at the rear end is connected to the working platform 4 via the leveler 3.

[0028] The swing drive mechanism is configured as a pair of telescopic cylinders 22. The swing drive mechanism uses a pair of telescopic cylinders 22, which has a compact structure, large driving force, and direct control. For two adjacent support frames 21 that swing relative to each other around the first axis, a telescopic cylinder 22 is arranged on each side of the first axis. The cylinder body end of the telescopic cylinder 22 is connected to the edge of one support frame 21, and the telescopic end of the telescopic cylinder 22 is connected to the edge of the other support frame 21. For two adjacent support frames 21 that swing relative to each other around the second axis 52, a telescopic cylinder 22 is arranged on each side of the second axis 52. The cylinder body end of the telescopic cylinder 22 is connected to the edge of one support frame 21, and the telescopic end of the telescopic cylinder 22 is connected to the edge of the other support frame 21.

[0029] The support frame 21 includes a main frame 211 and side frames 212 disposed on opposite sides of the main frame; between two adjacent support frames 21, the head end of one main frame 211 is hinged to the tail end of another main frame 211 via a hinge 23, and the two ends of the telescopic cylinder 22 are respectively connected to the side frames 212 on the same side of the two adjacent support frames 21.

[0030] One telescopic cylinder 22 extends while the other telescopic cylinder 22 retracts, causing adjacent support frames 21 to swing relative to each other around the first axis 51 or the second axis 52. Specifically, adjacent support frames 21 swing relative to each other left and right around the first axis 51, and swing relative to each other forward and backward around the second axis 52.

[0031] An angle sensor is installed on the support frame 21 to monitor the swing angle between two adjacent support frames 21. The controller is connected to the control end of the swing drive mechanism and the angle sensor respectively. Based on the angle data monitored in real time by the angle sensor, the controller precisely adjusts the swing angle between two adjacent support frames 21. In this way, by monitoring and precisely controlling the swing angle between two adjacent support frames 21 in real time, closed-loop control and intelligent planning of the motion trajectory of the work platform 4 are achieved, improving the precision and controllability of the operation and reducing the difficulty of operation.

[0032] The lower end of the end support frame 21 is connected to the support base 24, and the working platform 4 is mounted on the support base 24. Several levelers 3 are installed between the support base 24 and the working platform 4 to adjust the levelness of the working platform 4. In this way, the working platform 4 is always kept in a horizontal position under any boom posture, which effectively ensures the stability of the working platform 4 during operation and improves the accuracy of operation.

[0033] The leveler 3 includes a base 31, a first track support 32, a second track support 33, a support member 34, a leveling seat 35, and a leveling drive mechanism.

The second track support 33 can swing relative to the base 31 in the front and back directions. The second track support 33 is provided with a second track 331, which extends in the left and right directions and is arc-shaped and has a hollow structure.

[0035] The outer contour of the first track support 32 is a hemisphere at the top and a cylinder at the bottom. A groove is cut at the center of the hemisphere to form the first track 321. The outer contour of the second track support 33 is an arc shape. A hollowed-out groove is cut along the extension direction of the second track support 33 to form the second track 331.

[0036] The lower end of the support member 34 passes through the second track 331, and the support member 34 slides in conjunction with the second track 331. The lower end of the support member 34 slides in conjunction with the first track 321. The upper end of the support member 34 is provided with a leveling seat 35, which is connected to the bottom of the work platform 4.

[0037] To improve the stability of the lower end of the support member 34 in conjunction with the first track 321, a limiting post 341 is provided at the lower end of the support member 34, and limiting grooves 322 are formed on opposite sides of the first track 321, with the limiting post 341 fitting within the limiting grooves 322. When the lower end of the support member 34 slides along the second track 331, the limiting post 341 slides along the limiting grooves 322.

[0041] The first motor 611 is mounted on the support base 24. The output shaft of the first motor 611 is connected to the input shaft of the first reducer 621 via a coupling 64. The output shaft of the first reducer 621 is connected to the first rotating rod 631, which is rotatably connected to the bearing seat 311 on the opposite side of the base 31 of the first leveler 3.

The cross-section of the mating part on the first rotating rod 631 is also square, and the mating part of the first rotating rod 631 mates with the limiting hole. The output shaft of the first motor 611 rotates forward or backward by a set angle to drive the first rotating rod 631 to rotate forward or backward, thereby causing the first track support 32 of the first leveler 3 to swing relative to the base 31 in the left and right directions.

The output shaft of the second reducer 622 is connected to one end of the second track support 33 of the first leveler 3. The two ends of the second track support 33 are rotatably connected to bearing seats 311 on the opposite side of the base 31 of the first leveler 3.

The output shaft of the third motor 613 rotates forward or backward by a set angle to drive the second rotating rod 632 to rotate forward or backward, thereby causing the first track support 32 of the second leveler 3 to swing relative to the base 31 in the left and right directions.

[0044] The first rotating rod 631 is connected to one end of the second track support 33 of the second leveler 3. The two ends of the second track support 33 are rotatably connected to the bearing seats 311 on the opposite side of the base 31 of the second leveler 3. The first rotating rod 631 rotates in the forward or reverse direction, causing the second track support 33 of the second leveler 3 to swing relative to the base 31 in the forward and backward directions.

[0045] The fourth motor 614 is mounted on the support base 24. The output shaft of the fourth motor 614 is connected to the input shaft of the fourth reducer 624 via a coupling 64. The output shaft of the fourth reducer 624 is connected to one end of the second track support 33 of the third leveler 3. The second track support 33 is rotatably connected to the bearing seat 311 on the opposite side of the base 31 of the third leveler 3. The output shaft of the fourth motor 614 rotates forward or backward by a set angle to drive the second track support 33 of the third leveler 3 to swing relative to the base 31 in the forward and backward directions.

[0046] The other end of the second track support 33 of the first leveler 3 is connected to one end of the third rotating rod 633, which is rotatably connected to the bearing seat 311 on the opposite side of the base 31 of the third leveler 3. The first track support 32 of the third leveler 3 has a through-hole with a square cross-section, and the cross-section of the mating part on the third rotating rod 633 is also square, with the mating part of the third rotating rod 633 engaging with the limiting hole. The third rotating rod 633 rotates in either the forward or reverse direction, causing the first track support 32 of the third leveler 3 to swing relative to the base 31 in the left or right direction.

[0047] The other end of the second track support 33 of the third leveler 3 is connected to one end of the fourth rotating rod 634.

The two ends of the second track support 33 are rotatably connected to the bearing seats 311 on the opposite side of the base 31 of the fourth leveler 3. The second rotating rod 632 rotates in the forward or reverse direction, causing the second track support 33 of the fourth leveler 3 to swing relative to the base 31 in the forward and backward directions.

[0049] The leveling seats 35 of the four levelers 3 are connected to the four corners of the work platform 4. The leveling seats 35 at the four corners can be swung in any direction (front, back, left, right) to adjust the levelness of the work platform 4.

[0050] The leveler 3, through its ingenious design of circular arc tracks and swing supports (first track support 32, second track support 33), achieves multi-degree-of-freedom leveling functionality with a relatively simple mechanical structure, avoiding the problems of complex structure, heavy weight, and high cost of traditional multi-stage transmission leveling systems. The entire system improves performance while also ensuring structural reliability and economical manufacturing costs.

[0051] An intelligent aerial work platform includes a chassis 7, a turntable 8, and a lifting hydraulic cylinder 9. It also includes the aforementioned integrated biomimetic elephant trunk multi-joint boom assembly. The rear end of the main boom 1 is connected to a support boom seat 81 on the turntable 8. One end of the lifting hydraulic cylinder 9 is hinged to the support boom seat 81, and the other end of the lifting hydraulic cylinder 9 is hinged to the main boom 1. The main boom 1 includes several telescopic booms 11 arranged in a nested configuration. Adjacent telescopic booms 11 can extend and retract relative to each other. The front end of the first telescopic boom 11 is connected to the upper end of the first-end support frame 21, and the rear end of the last telescopic boom 11 is connected to the support boom seat 81 on the turntable 8.

[0052] The rotation of the turntable 8 relative to the chassis 7 causes the main boom 1, the boom 2, and the work platform 4 to swing significantly left and right. The extension and retraction of the lifting hydraulic cylinder 9 causes the main boom 1 to swing significantly up and down relative to the support boom seat 81. The relative extension and retraction of adjacent telescopic booms 11 causes the boom 2 and work platform 4 to move significantly. The relative swinging between adjacent support frames 21 via a swing drive mechanism allows the boom 2 to bend in any direction (forward, backward, left, right), mimicking an elephant's trunk, enabling flexible and wide-range coverage of the work platform 4's complex spatial trajectory and precise posture adjustment. Thus, through the above coordinated operations, the work platform 4 achieves precise adjustment with a large number of degrees of freedom, increasing its working range and operational flexibility. When encountering obstacles such as pipelines, eaves, or trees during operation, the relative swinging between adjacent support frames 21 of the boom 2 allows the work platform 4 to extend and bypass the obstacles, achieving "obstacle avoidance operation."

[0053] The leveling devices 3 located at the four corners of the work platform 4 can swing in any direction (front, back, left, right) to adjust the level of the work platform 4, improve the stability of the work platform 4 during operation, and thus improve the accuracy of the operation.

[0054] Example 2: Please refer to Figure 13 , Figure 14 As shown, the difference between this embodiment and embodiment 1 is that: the leveler 3 is set to one, and the leveler 3 is arranged in the middle position between the support base 24 and the working platform 4.

[0055] The fifth motor 615 is mounted on the support base 24. The output shaft of the fifth motor 615 is connected to the input shaft of the fifth reducer 625 via a coupling 64. The output shaft of the fifth reducer 625 is connected to the first track support 32 of the leveler 3. The opposite ends of the first track support 32 are rotatably connected to the bearing seats 311 on opposite sides of the base 31 of the leveler 3 via shafts. The output shaft of the fifth motor 615 rotates a set angle in either the forward or reverse direction to drive the first track support 32 to swing relative to the base 31 in the left or right direction.

[0056] The sixth motor 616 is mounted on the support base 24. The output shaft of the sixth motor 616 is connected to the input shaft of the sixth reducer 626 via a coupling 64. The output shaft of the sixth reducer 626 is connected to the second track support 33 of the leveler 3. The two ends of the second track support 33 are rotatably connected to the bearing seats 311 on opposite sides of the base 31 of the leveler 3 via shafts. The output shaft of the sixth motor 616 rotates forward or backward by a set angle to drive the second track support 33 to swing relative to the base 31 in the forward and backward directions.

[0057] The leveling seat 35 of the leveler 3 is connected to the middle position of the work platform 4. The leveling seat 35 can be swung in any direction (front, back, left, right) to adjust the levelness of the work platform 4.
