Description

Technical Field

[0001] This invention relates to the field of aerial work platform technology, and more specifically to a multi-functional aerial work platform based on magnetic transport. Background Technology

[0002] Aerial work platforms are multi-functional engineering vehicles designed for high-altitude operations. Their core function is to safely and efficiently transport personnel and equipment to designated heights using machinery, platforms, or other devices to complete various high-altitude tasks. In recent years, with the acceleration of urbanization and the continuous advancement of infrastructure construction, their market demand has continued to grow. These devices are not only widely used in industries such as construction, power, and landscaping, but also demonstrate enormous application potential in specialized fields such as petrochemicals, communications, and disaster relief. As the requirements for aerial work platforms increase, traditional aerial work platforms can no longer meet the needs of social production; therefore, structural optimization of aerial work platforms has become an inevitable trend.

[0003] Currently, the main types of aerial work platforms include: aerial work vehicles, which provide a stable working platform but are difficult to quickly transport bulk materials or independently hoist heavy equipment; conveyor vehicles, such as ladder trucks, which focus on material transport efficiency but lack a safe platform for workers to work flexibly for extended periods; and cranes, which only have lifting capabilities, cannot quickly transport materials, and cannot provide a working platform. When lifting heavy objects to a high altitude, they require workers from other equipment for docking and installation, a process that often leads to high safety risks and coordination costs due to poor communication and positioning difficulties. Furthermore, aerial work platforms, conveyor vehicles, and cranes cannot efficiently meet the collaborative needs of personnel operations and material transport when working individually. When working together, they face problems such as waiting time, complex command structures, low work efficiency, and overlapping safety risks. In critical scenarios such as emergency rescue, their deployment flexibility remains limited, and their rapid response capability is insufficient. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-functional aerial work platform based on magnetic transport, which combines at least two of the following capabilities: rapid material transport, lifting, and high-altitude precision operations, thereby improving the operational flexibility, accessibility, and collaborative efficiency of the aerial work platform.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A multi-functional aerial work platform based on magnetic transport includes: The vehicle chassis has several outrigger mechanisms installed on it. The turntable is rotatably connected to the vehicle chassis; Telescopic boom, several telescopic boom sections are nested in sequence, and adjacent telescopic boom sections can extend and retract relative to each other. The first telescopic boom section is connected to the turntable. The working platform is located at the end of the telescopic boom section; The magnetic trolley is magnetically connected to the outer surface of each telescopic boom section, and the magnetic trolley can move relative to the telescopic boom. The magnetic trolley is equipped with a material box that can be loaded with materials.

[0006] Furthermore, the magnetic trolley includes a trolley chassis, tracked wheels, tracks, magnetic blocks, and a driving mechanism, wherein the material box is mounted on the trolley chassis; The front and rear sides of the trolley chassis are rotatably connected to track wheels, and the two track wheels are connected to a track. Multiple magnetic blocks are arranged at equal intervals on the track, and the magnetic blocks can magnetically connect to the outer surface of each telescopic boom section. The drive mechanism is powered by the track wheels to rotate them.

[0007] Furthermore, an assembly opening is provided on the track, and a first step is provided on the side wall of the assembly opening; It also includes a magnetic block holder and a limiting member. One end of the magnetic block is provided with a second step. The inner end of the magnetic block is assembled into the assembly opening from the outside of the track, and the second step cooperates with the first step. The inner end of the magnetic block holder is assembled and connected to the inner end of the magnetic block from the inside of the track. The outer end of the magnetic block holder is connected to the inside of the track via the limiting member.

[0008] Furthermore, the limiting component includes a limiting post, a limiting wheel, and a limiting flexible rail; Each magnetic block base has a limiting post on its left and right sides facing each other at its outer end. There is an assembly space between the limiting post and the outer end face of the magnetic block base. A limiting wheel is rotatably connected to the limiting post. The limiting soft rail runs through the corresponding assembly space on each magnetic block seat.

[0009] Furthermore, a limiting annular groove is provided at the middle position of the circumference side of the track wheel, and the limiting flexible rail cooperates with the limiting annular groove.

[0010] Furthermore, the magnetic trolley also includes a connecting rod and a guide seat, with one end of the connecting rod hinged to the rear end or both ends of the trolley chassis, and the other end of the connecting rod hinged to the guide seat; Each telescopic boom section has a limit groove along the axial direction on its outer surface. After each telescopic boom section extends relative to the other, the limit grooves on each telescopic boom section are connected in sequence, and the guide seat is fitted into the limit groove.

[0011] Furthermore, in the two adjacent nested telescopic boom sections, the front end of the outer telescopic boom limiting groove is provided with an extension, the extension is arranged at an angle, and the end of the extension extends into the inner telescopic boom limiting groove. When the trolley chassis descends at a speed exceeding the set speed, the guide seat impacts the extension, causing the extension to break or deform, and the guide seat becomes embedded in the gap between two adjacent nested telescopic boom sections.

[0012] Furthermore, the magnetic trolley also includes a support rod, a pushing block, a lead screw, a lead screw, and a drive motor; The front end of the material box is hinged to the front end of the trolley chassis, and the rear end of the material box is hinged to one end of the support rod. The other end of the support rod is hinged to the push block, and the nut is provided on the push block. At least one end of the lead screw is rotatably connected to the chassis of the trolley via a bearing, one end of the lead screw is driven by the drive motor, and the lead screw is engaged with the lead nut.

[0013] Furthermore, it also includes a hook and a lifting drive mechanism. The hook is connected to the end telescopic boom, and the hook is connected to the lifting drive mechanism via a transmission cable. The lifting drive mechanism drives the hook to rise and fall via the transmission cable.

[0014] Furthermore, the lifting drive mechanism includes a fixed pulley, a movable pulley, and a winch. Each section of the telescopic boom is equipped with at least one fixed pulley, the hook is equipped with one movable pulley, the winch is mounted on the rotary table, one end of the transmission rope is connected to the end of the last section of the telescopic boom, the transmission rope passes through the movable pulley and each fixed pulley in sequence, and the other end of the transmission rope is connected to the winch.

[0015] Compared with the prior art, the multi-functional aerial work platform based on magnetic transport provided by the present invention has the following significant advantages: 1. This invention integrates aerial work platform, material conveying, and lifting functions into a single device, achieving "multi-purpose functionality in one machine." By incorporating a magnetic trolley that can move along the telescopic boom, rapid material conveying can be completed simultaneously with aerial work. Combined with the hook structure on the final boom section, it further enhances lifting and hoisting capabilities. These three functions can be executed independently or collaboratively, effectively solving the problems of long waiting times, complex command structures, low efficiency, and overlapping safety risks inherent in traditional equipment during collaborative operations.

[0016] 2. The magnetic trolley of this invention adopts a tracked structure and magnetic adsorption method. It utilizes the closed magnetic circuit formed by the magnetic blocks and the telescopic boom to generate a stable normal adsorption force, ensuring the trolley is firmly attached to the telescopic boom. The magnetic blocks on the track adopt a modular installation structure and cooperate with the limiting annular grooves on the track wheels through limiting soft rails, ensuring the smoothness and guiding accuracy of the track operation and effectively preventing the trolley from deviating or falling off during transportation.

[0017] 3. This invention features a limiting groove and an extension structure on the telescopic boom, which works in conjunction with the guide seat at the rear of the magnetic trolley. When the trolley slides down uncontrollably, the guide seat impacts the extension, deforming or breaking it and embedding it into the gap between adjacent booms, forming a mechanical buffer lock that effectively prevents the trolley from falling and significantly improves the safety of high-altitude material transportation.

[0018] 4. The magnetic trolley of this invention is equipped with an adjustable tilting hopper, which can automatically adjust the hopper's posture according to the lifting angle of the telescopic boom, keeping it level and preventing materials from slipping during transportation. Meanwhile, the hook section adopts a lifting structure using a combination of moving and fixed pulleys, with the transmission rope arranged along the telescopic boom. The structure is compact, occupies little space, and does not affect the normal extension and retraction of the boom or platform operations.

[0019] 5. By setting up a weighing sensor, a speed sensor, and a controller, this invention can monitor the magnetic trolley and its load weight in real time, and automatically adjust the upper limit of the driving speed according to the load, ensuring that the trolley can operate stably within a safe speed range under different loads, further improving the reliability and intelligent control level of the transportation process.

[0020] In summary, the multi-functional aerial work platform based on magnetic transport provided by this invention has achieved significant technological advancements in functional integration, operational coordination, transportation safety, posture adaptation, and intelligent control, and has high practical value and promising prospects for widespread application.

Certain embodiments of the invention will be described more fully below with reference to the accompanying drawings, and some, but not all, of these embodiments will be shown. In fact, various embodiments of the invention can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to enable the invention to meet applicable legal requirements.

[0023] In the description of this invention, it should be noted that the terms "inner," "outer," "upper," "lower," "front," and "rear," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In this embodiment of the invention, a multi-functional aerial work platform vehicle based on magnetic transport is provided. Please refer to [reference needed]. Figures 1 to 18 As shown.

[0025] A multi-functional aerial work platform based on magnetic transport includes a chassis 1, a turntable 2, a telescopic boom 3, a work platform 4, a magnetic trolley 5, a material box 6, and a hook 7.

[0026] Several outrigger mechanisms 11 are installed at the bottom of the chassis 1. The outrigger mechanisms 11 provide stable support for the chassis 1 and its components, enabling the aerial work vehicle to operate safely and stably.

[0027] The turntable 2 is rotatably connected to the chassis 1. The turntable 2 can rotate horizontally relative to the chassis 1, thereby driving the components on it to rotate horizontally to a set position.

[0028] Four telescopic boom sections 3 are nested sequentially, with adjacent sections capable of relative extension and retraction. The boom drive mechanism drives the relative extension and retraction of adjacent sections. The first telescopic boom section 3 (the lowest section) is hinged to the turntable 2. One end of the lifting hydraulic cylinder 21 is hinged to the turntable 2, and the other end is hinged to the first telescopic boom section 3. The extension and retraction of the lifting hydraulic cylinder 21 relative to the fixed end causes the telescopic boom 3 to swing in the up and down directions.

[0029] The work platform 4 is located at the end of the last telescopic boom 3 (the uppermost telescopic boom 3). Through the rotation of the turntable 2 and the extension and retraction of the telescopic boom 3, the work platform 4 is moved to a set position in space, and the operator performs high-altitude work on the work platform 4.

[0030] In this embodiment, the end of the telescopic boom 3 is connected to the work platform 4 via a flying arm 41. The flying arm 41 swings relative to the telescopic boom 3 to further increase the operational flexibility of the work platform 4.

[0031] The magnetic trolley 5 is magnetically connected to the outer surface of each telescopic boom 3, and the magnetic trolley 5 can move relative to the telescopic boom 3. The magnetic trolley 5 is equipped with a material box 6 that can be loaded with materials.

[0032] The magnetic trolley 5 includes a chassis 51, tracked wheels 52, tracks 53, magnetic blocks 54, and a driving mechanism. A material box 6 is mounted on the chassis 51. A tracked wheel 52 is rotatably connected to each side of the chassis 51, front and rear, with the tracks 53 connecting the two tracked wheels. The tracked wheels 52 are configured as gears, and the inner wall of the tracks 53 is configured as a toothed belt, with the gears meshing with the toothed belt. Multiple magnetic blocks 54 are evenly spaced on the tracks 53, magnetically connecting to the outer surfaces of each telescopic boom section 3. The driving mechanism is powered by the tracked wheels 52, driving them to rotate. The driving mechanism is a hydraulic motor mounted on the chassis 51, connected to the input shaft of a transmission, and the output shaft of the transmission is connected to the tracked wheels 52.

[0033] The magnetic trolley 5 travels along each section of the telescopic boom 3 as follows: During adsorption: When the track 53 drives the magnetic block 54 close to the telescopic boom 3, the magnetic block 54 and the telescopic boom 3 form a closed magnetic circuit. The magnetic lines of force form a loop through the telescopic boom 3, generating a large normal adsorption force. The adsorption force is perpendicular to the telescopic boom 3, firmly pressing the magnetic trolley 5 onto the telescopic boom 3.

[0034] Upon disengagement: As track 53 rotates with track wheel 52, and magnetic block 54 is about to disengage from telescopic boom 3, the distance between magnetic block 54 and telescopic boom 3 increases, and the magnetic circuit is "disconnected". At this time, the magnetic force at the end of track 53 where magnetic block 54 disengages from telescopic boom 3 decreases sharply, allowing track 53 to be easily pulled away from telescopic boom 3 by track wheel 52.

[0035] When track 53 rotates around track wheel 52, a peeling angle is formed between the contact surface of track 53 and telescopic boom 3. During this peeling process, the direction of the resultant force of magnetic force and pulling force changes. Since magnetic force is inversely proportional to the square of distance, as long as the initial peeling force exceeds the maximum static friction force, and the magnetic block 54 moves slightly away from the telescopic boom 3 by a small distance (on the millimeter scale), the magnetic force will drop sharply. At this time, the hydraulic motor only needs to provide torque to overcome the "residual magnetic attraction" and "track 53 friction" to easily pull track 53 up.

[0036] An assembly opening 531 is provided on the track 53, and a first step 532 is provided on the side wall of the assembly opening 531. A second step 541 is provided at one end of the magnetic block 54. The inner end of the magnetic block 54 is assembled into the assembly opening 531 from the outside of the track 53, and the second step 541 mates with the first step 532. The inner end of the magnetic block seat 55 is assembled and connected to the inner end of the magnetic block 54 from the inside of the track 53, and the outer end of the magnetic block seat 55 is connected to the inside of the track 55 via a limiting member. An assembly hole is provided in the middle of the magnetic block seat 55, and a threaded hole is provided on the end face of the magnetic block 54. A screw 551 passes through the assembly hole on the magnetic block seat 55 and is threaded into the threaded hole on the magnetic block 54 to realize the assembly connection between the magnetic block seat 55 and the magnetic block 54.

[0037] The limiting components include limiting posts 561, limiting wheels 562, and limiting rails 563. Each magnetic block base 55 has a supporting ear 552 positioned opposite each other on its left and right outer ends. Each supporting ear 552 has at least one limiting post 561. The left and right limiting posts 561 are arranged opposite each other, with an assembly space between the limiting post 561 and the outer end face of the magnetic block base 55. A limiting wheel 562 is rotatably connected to the limiting post 561. The limiting rail 563 passes through the corresponding assembly space on each magnetic block base 55. The limiting rail 563 has an internal steel wire rope braided strip structure, and a protective layer is laid on the outside of the strip structure.

[0038] A limiting annular groove 521 is provided at the middle position of the circumference of the track wheel 52, and a limiting flexible rail 563 cooperates with the limiting annular groove 521. In this way, the limiting flexible rail 563 is used not only for limiting the assembly of the aforementioned magnetic block seat 55, but also for guiding the operation of the track wheel 52.

[0039] The magnetic trolley 5 also includes a connecting rod 571 and a guide seat 572. One end of the connecting rod 571 is hinged to both ends of the trolley chassis 51, and the other end of the connecting rod 571 is hinged to the guide seat 572. Each telescopic boom section 3 has a limiting groove 31 along its axial direction on its outer surface. After each telescopic boom section 3 extends relative to the other, the limiting grooves 31 on each telescopic boom section 3 are sequentially aligned, and the edge of the guide seat 572 fits into the limiting groove 31. Thus, through the cooperation of the guide seat 572 and the limiting groove 31, the magnetic trolley 5 is guided as it travels along the telescopic boom section 3, preventing it from tipping over.

[0040] Rollers 573 are rotatably connected to the upper and lower ends of the guide seat 572. The edge of the guide seat 572 and the lower roller 573 are located inside the limiting groove 31, while the upper roller 573 is located outside the limiting groove 31. The lower roller 573 rolls in contact with the inner wall of the limiting groove 31, and the upper roller 573 rolls in contact with the outer side of the limiting groove 31. A wear-resistant slider is provided on the side of the guide seat 572 that contacts the limiting groove 31. This reduces wear between the guide seat 572 and the limiting groove 31.

[0041] In the two nested telescopic boom sections 3, an extension 32 is provided at the front end of the limiting groove 31 of the outer telescopic boom section 3. The extension 32 is arranged at an angle, and its end extends into the limiting groove 31 of the inner telescopic boom section 3. In this way, a bridge is formed between the limiting grooves 31 of the two nested telescopic boom sections 3, allowing the guide seat 572 to move smoothly between the limiting grooves 31 of the two nested telescopic boom sections 3.

[0042] When the chassis 51 of the trolley descends at a speed exceeding the set speed, the guide seat 572 impacts the extension 32, causing the extension 32 to break or deform. The guide seat 572 then embeds itself into the gap between two adjacent nested telescopic boom sections 3. In this way, if the magnetic trolley 5 slips out of control, the guide seat 572, embedded in the gap between the two adjacent nested telescopic boom sections 3, provides a buffer lock to prevent the magnetic trolley 5 from falling.

[0043] The magnetic trolley 5 and its loading box 6 carry different weights of materials, and therefore have different set speeds. The magnetic trolley 5 needs to move along the telescopic boom 3 at a speed lower than the set speed.

[0044] A load cell is installed on the material bin 6, and the controller is connected to both the load cell and the control terminal of the hydraulic motor via signal cables. Additionally, a speed sensor is installed at the location of the hydraulic motor shaft, and the controller is also connected to the speed sensor via a signal cable. Thus, the weight data monitored in real time by the load cell is uploaded to the controller. The controller retrieves the weight data of the magnetic trolley 5 and the material bin 6 from the storage unit, calculates the current set speed, and then controls the hydraulic motor to drive the magnetic trolley 5 to move at a speed lower than the current set speed. Furthermore, the speed sensor provides real-time feedback on the output speed of the hydraulic motor shaft, corresponding to the real-time monitoring of the magnetic trolley 5's movement speed.

[0045] The magnetic trolley 5 also includes a support rod 581, a pushing block 582, a nut, a lead screw 583, and a drive motor 584. The front end of the material box 6 is hinged to the front end of the trolley chassis 51, and the rear end of the material box 6 is hinged to one end of the support rod 581. The other end of the support rod 581 is hinged to the pushing block 582, and a nut is mounted on the pushing block 582. The lead screw 583 is arranged along the front-rear direction of the trolley chassis 51. Both ends of the lead screw 583 are rotatably connected to the trolley chassis 51 via bearings. One end of the lead screw 583 is driven by the drive motor 584, and the lead screw 583 engages with the nut. The output shaft of the drive motor 584 is connected to the lead screw 583. Rotation of the output shaft of the drive motor 584 drives the lead screw 583 to rotate. Through the engagement of the lead screw 583 with the nut, and the connection of the pushing block 582 to the material box 6 via the support rod 581, the push block 582 moves along the front-rear direction, thereby changing the tilt angle of the material box 6. Thus, the tilt angle of the material box 6 is adjusted according to the lifting angle of the telescopic boom 3, so that the material box 6 can maintain a horizontal posture.

[0046] The hook 7 is connected to the last section of the telescopic boom 3. The hook 7 is connected to the lifting drive mechanism via the transmission rope 71. The lifting drive mechanism drives the hook 7 to rise and fall via the transmission rope 71.

[0047] The lifting drive mechanism includes a fixed pulley 72, a movable pulley 73, and a winch 74. A fixed pulley 72 is installed at the end of each telescopic boom section 3, and another fixed pulley 72 is installed in the middle of the first telescopic boom section 3. The hook 7 is mounted on a hook seat 75, and a movable pulley 73 is installed on the hook seat 75. The winch 74 is mounted on a rotary table 2. One end of the drive rope 71 is connected to the end of the last telescopic boom section 3, and the drive rope 71 passes sequentially through the movable pulley 73 and each fixed pulley 72. The other end of the drive rope 71 is connected to the winch 71. By rotating the winch 71 in either the forward or reverse direction, the drive rope 71 is wound up or unwound, thereby raising or lowering the hook 7.

[0048] The present invention has been described in detail with reference to the accompanying drawings. Based on the above description, those skilled in the art should have a clear understanding of the multi-functional aerial work platform based on magnetic transport of the present invention. Of course, the specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention.
