Description

Technical Field

[0001] This invention relates to the field of lifting operation technology, and more specifically, to a mobile manned lifting platform. Background Technology

[0002] In the daily operation and maintenance of large-scale water conservancy projects such as locks and ship lifts, high-altitude and deep-pit operations are frequently required. For example, high-altitude operations are carried out on the top of the lock head and the upper structure of the miter gate, and deep-pit operations are carried out at the bottom of the lock chamber, water conveyance corridor and gate slot.

[0003] Current aerial work operations primarily rely on telescopic boom aerial work platforms, which typically use wheeled chassis. Their mobility and passability depend on relatively flat and firm road conditions. However, at water conservancy construction sites, such as dam crests, sluice gate edges, and maintenance platforms, the terrain is often narrow and uneven, or there are temporary obstacles, making it difficult for wheeled chassis to move and position stably, affecting the scope and efficiency of operations. Existing deep pit or vertical surface operations mostly use electric suspended platforms. These platforms require complex and bulky installation and suspension mechanisms, typically including front / rear supports, front / middle / rear beams, and numerous counterweights, and must be erected at a stable support point at the top of the building's working surface. On special structures such as locks and ship lifts, which are complex in structure, have limited top space, or lack standard suspension points, the installation and dismantling of this mechanism are quite difficult. This limits the applicable scenarios and mobility of the equipment.

[0004] Therefore, current high-altitude and deep-pit operations rely on specialized equipment with single functions, which has significant limitations in complex construction environments. There is a need to design a mobile manned lifting platform to achieve the core objectives of dual-purpose functionality and flexibility and efficiency, meeting the maintenance and repair needs of large-scale water conservancy projects in complex and harsh environments.

[0021] It should be noted that the terms "a" and "a plurality of" used in this invention are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0022] To address the problems existing in the aforementioned related technologies, the present invention provides a mobile manned lifting platform.

[0023] See Figures 1 to 3As shown, the present invention provides a mobile manned lifting platform, including a chassis mechanism, multiple folding support legs 21, a folding arm assembly, a drive assembly, and a working assembly. The chassis mechanism includes a tracked chassis 11 and a rotary drive component 12, the rotary drive component 12 being mounted on the tracked chassis 11; multiple folding support legs 21 are disposed on the tracked chassis 11 for supporting the chassis mechanism during operation; the folding arm assembly includes a first folding arm 31 and a second folding arm 32, the first end of the first folding arm 31 being hinged to the rotary drive component 12, and the first end of the second folding arm 32 being hinged to the second end of the first folding arm 31; the drive assembly includes a first drive component 41 and a... The second drive component 42 is connected between the first drive component 41 and the rotary drive component 12, and is used to drive the first folding arm 31 to rotate relative to the rotary drive component 12; the second drive component 42 is connected between the first folding arm 31 and the second folding arm 32, and is used to drive the second folding arm 32 to rotate relative to the first folding arm 31; it includes a climbing basket 51 and a suspended basket 52. The climbing basket 51 is installed at the second end of the second folding arm 32 through a leveling mechanism; the suspended basket 52 is connected to the first folding arm 31 through a suspension mechanism 6; wherein, by switching between using the climbing basket 51 and the suspended basket 52, the lifting platform can be used for high-altitude operation mode or deep pit operation mode respectively.

[0024] Furthermore, the leveling mechanism ensures that the basket 51 remains horizontal during lifting, providing a safe and stable platform for high-altitude operations. The suspension mechanism 6 provides reliable redundant suspension for the basket 52.

[0025] It should be noted that this invention integrates two types of work support devices: the aerial work platform 51 and the suspended platform 52, which can be quickly switched to form either a high-altitude work mode or a deep-pit work mode. This changes the traditional work method that relies on two separate systems: an aerial work vehicle and an electric suspended platform.

[0026] The articulated arm assembly, consisting of the first articulated arm 31 and the second articulated arm 32, combined with the drive of the first drive component 41 and the second drive component 42, can flexibly achieve a wide range of pitch and extension. It can lift the basket 51 to a high altitude or lower it into a deep pit via a suspension mechanism. Therefore, this equipment can cover multiple operational scenarios, including high-altitude and deep-pit operations, with just a single unit. In particular, addressing the challenges of narrow and uneven roads at water conservancy construction sites, the tracked chassis 11 used in this solution has the advantages of a larger ground contact area and lower ground pressure compared to traditional wheeled chassis, allowing it to easily traverse soft and rugged terrain. Simultaneously, the stable support formed by the unfolding of multiple folding support legs 21 during operation ensures the stability of the equipment when operating on complex terrain. In addition, the slewing drive 12 can drive the articulated boom assembly to rotate in the horizontal plane relative to the tracked chassis 11, giving the entire articulated boom assembly the ability to rotate in the horizontal plane, enabling the working device to flexibly adjust the coverage range in a limited space, and enhancing the mobility and positioning accuracy in narrow and confined spaces such as locks and dams.

[0027] In one embodiment of the present invention, the mobile manned lifting platform includes four foldable support legs 21, which are respectively disposed at the four corners of the tracked chassis 11; each foldable support leg 21 includes a first leg rod, a second leg rod and a support leg drive cylinder, one end of the first leg rod is hinged to the tracked chassis 11, and the other end is hinged to the second leg rod through a rotating joint, and the two ends of the support leg drive cylinder are respectively hinged to the tracked chassis 11 and the rotating joint.

[0028] It should be noted that the extension and retraction of the outrigger drive cylinder can directly and efficiently control the unfolding and retraction of the entire folding support leg 21. When unfolded, it forms a stable support surface, and when retracted, it can fit tightly against the side of the tracked chassis 11, significantly reducing the width of the equipment during travel and ensuring passability in narrow spaces. The four folding support legs 21 are symmetrically arranged at the four corners of the tracked chassis 11. When they extend synchronously and support the ground, they can stably lift the entire chassis mechanism off the ground, forming a large, rigid platform supported by four independent points. This evenly transmits the overturning moment and dynamic load generated by the movement of the folding arm assembly during operation to the ground, fundamentally overcoming the risks of settlement, swaying, or even overturning that may occur when traditional wheeled equipment operates on soft or uneven ground. This stable support mechanism, combined with the superior terrain adaptability provided by the tracked chassis 11, ensures that the lifting platform can move flexibly into place and obtain an extremely stable working foundation in complex and demanding construction sites such as locks and dam tops, providing a fundamental guarantee for subsequent precise and safe high-altitude or deep-pit operations.

[0029] In one embodiment of the present invention, the first driving member 41 is a first luffing cylinder, the cylinder body end of which is hinged to the rotary driving member 12, and the piston rod end of which is hinged to the first folding arm 31; the second driving member 42 is a second luffing cylinder, the cylinder body end of which is hinged to the first folding arm 31, and the piston rod end of which is hinged to the second folding arm 32.

[0030] It should be noted that the use of the first and second luffing cylinders as driving components, connected by a hinge, is the core of achieving the equipment's wide-range, highly flexible, and stable and reliable operation. The cylinder body of the first luffing cylinder is hinged to the slewing drive 12, and the piston rod drives the first articulated boom 31. This arrangement provides powerful initial lifting force and direct, precise control over the pitch angle of the first articulated boom 31. The cylinder body of the second luffing cylinder is hinged to the first articulated boom 31, and the piston rod drives the second articulated boom 32, allowing the movement of the second articulated boom 32 to be based on the first articulated boom 31, achieving a combined movement of the two-stage boom. This drive and connection design enables the articulated boom assembly to achieve an ultra-wide spatial coverage, from a deep pit horizontally below to a high altitude vertically above. Its hydraulic drive system boasts advantages such as high output, stable speed, easy stepless speed regulation, and lock-in retention. This ensures smooth movement and precise positioning when lifting or lowering the work components (elevation basket 51 or suspended basket 52), and reliable locking at any position, providing the necessary dynamic stability and static safety for high-altitude and deep-pit operations. It is a key performance guarantee for the equipment to achieve dual-function operation and flexibly adjust its working position and posture in confined spaces.

[0031] In one embodiment of the present invention, the first folding arm 31 is a T-beam structure and includes a vertical section and a horizontal section; one end of the vertical section is hinged to the rotary drive member 12, and the other end is hinged to the first end of the second folding arm 32; the two ends of the horizontal section are respectively provided with a double-head structure 311 for connecting the suspension mechanism 6.

[0032] It should be noted that the T-beam structure of the first folding arm 31 rigidly integrates the vertical and horizontal sections, enabling the vertical section to efficiently bear the rotational driving force from the slewing drive component 12 and the lifting force from the first luffing cylinder, and smoothly transmit it to the second folding arm 32 or the horizontal section, which serves as the execution end. The symmetrically arranged double-head structure 311 at both ends of the horizontal section provides two independent and stable mechanical anchor points for the suspension mechanism 6 of the basket 52. This double-head design constitutes a physically redundant load-bearing system, fundamentally improving the suspension safety margin in deep pit operation mode. Even if a single wire rope or a single connection point malfunctions, the other system can still provide effective support to prevent the risk of falling. At the same time, this integrated design achieves the integration of high-altitude lifting and deep pit suspension functions within a limited space, which not only simplifies the structure and reduces the weight, but also makes the switching between the two operation modes faster and more direct.

[0033] See Figure 4 and Figure 5As shown, in one embodiment of the present invention, the suspension mechanism 6 includes two lifting units corresponding to the two ends of the suspended basket 52. Each lifting unit includes a working rope 62, a safety rope 63, a hoist 64, and a safety lock. The hoist 64 and the safety lock are respectively installed at one end of the suspended basket 52. One end of the working rope 62 and the safety rope 63 are respectively passed through the hoist 64 and the safety lock, and the other end is respectively connected to the double-head structure 311 and secured by rope clamps.

[0034] Furthermore, the lifting unit can refer to the electric suspended platform system used in construction, and may include a working rope 62, a safety rope 63, a hoist 64, and a safety lock. Specifically, the hoist 64 is a winch device with integrated braking and electromechanical components, responsible for winding and releasing the working wire rope 62, providing the main lifting power; the safety lock is an independent safety device that automatically locks the safety wire rope 63 when the working wire rope 62 breaks or the suspended platform 52 descends at excessive speed, providing redundant protection. One end of the working wire rope 62 and the safety wire rope 63 are respectively firmly fixed to the corresponding double-head structure 311, and the other end is respectively passed through the hoist 64 and the safety lock, and finally reliably connected to the suspended platform 52 by fasteners such as rope clamps, forming two independent and mutually backup bearing paths. This double-rope, double-safety-lock suspension design is an existing suspended platform technology solution, which is directly integrated into the mobile platform of this invention, providing a proven and highly reliable suspension guarantee that meets safety standards for the deep pit operation mode of this invention.

[0035] In one embodiment of the present invention, the leveling mechanism includes a mounting plate 71 and a leveling drive cylinder 72; One end of the mounting plate 71 is connected to the second end of the second folding arm 32 via a hinge shaft; the climbing basket 51 is mounted on the mounting plate 71; the leveling drive cylinder 72 is connected between the second folding arm 32 and the mounting plate 71, and is used to drive the mounting plate 71 to rotate around the hinge shaft to adjust and achieve that the climbing basket 51 is in a horizontal state.

[0036] Furthermore, a typical structure of the leveling mechanism may include a mounting plate 71 hinged to the end of the second folding arm 32, one or a set of leveling drive cylinders 72 (usually hydraulic cylinders), and an angle sensor and hydraulic control system. Its working principle is as follows: when the second folding arm 32 and / or the first folding arm 31 undergoes luffing motion, the posture of the mounting plate 71 will tilt accordingly. At this time, the angle sensor (such as a tilt sensor) mounted on the mounting plate 71 detects its horizontal angle deviation in real time and feeds the signal back to the control system. The control system then issues a command to the leveling drive cylinder 72 according to the deviation value, driving it to perform a corresponding extension and retraction action, thereby adjusting the rotation angle of the mounting plate 71 around its hinge axis in the opposite direction, counteracting the tilt caused by the movement of the folding arm assembly. Ultimately, the aerial work platform 51 mounted on the mounting plate 71 automatically maintains a horizontal state throughout the entire operation, providing a stable and safe working plane for the workers. This ensures the basic safety and reliability of the invention in high-altitude operation mode.

[0037] In one embodiment of the present invention, the leveling mechanism further includes a rotation mechanism 73, which is disposed between the mounting plate 71 and the climbing basket 51, and the rotation axis of the rotation mechanism 73 is perpendicular to the plane on which the mounting plate 71 is located; the climbing basket 51 is mounted on the rotating part of the rotation mechanism 73 and is driven by the rotation mechanism 73 to rotate horizontally relative to the mounting plate 71.

[0038] Furthermore, the slewing mechanism 73 is a functional component disposed between the mounting plate 71 and the climbing basket 51, used to drive the climbing basket 51 to rotate in the horizontal plane. This mechanism is essentially a general technology for achieving horizontal rotation of a platform or working device. Its typical structure typically includes: a slewing bearing (or turntable bearing) fixed to the mounting plate 71, the slewing bearing having an inner ring, an outer ring, and rolling elements; a rotating seat fixedly connected to the bottom of the climbing basket 51, the rotating seat being tightly connected to the ring (e.g., the outer ring) of the slewing bearing; and a slewing drive device, which is typically composed of a hydraulic motor or servo motor integrated with a reducer, with its output pinion meshing with an internal gear ring on the other ring (e.g., the inner ring) of the slewing bearing. When the slewing drive device receives a command from the control system, it drives the pinion to rotate. The meshing motion of the pinion and the internal gear ring is converted into a low-speed, high-torque, precise slewing motion of the rotating seat relative to the mounting plate, thereby driving the entire climbing basket 51 to rotate horizontally.

[0039] Meanwhile, the aforementioned slewing mechanism 73, in terms of core structure and working principle, belongs to the same technical category as the aforementioned slewing drive component 12, namely, a mature drive module that enables relative rotation of components in the horizontal plane. The difference lies in the size of the slewing bearing used in the slewing drive component 12, its extremely high load-bearing capacity (axial, radial, and overturning), and the significantly higher power and torque of its drive device compared to the slewing mechanism 73. It needs to overcome the enormous overturning moment generated by the entire cantilever to ensure a smooth, sway-free slewing process. The load on the slewing mechanism 73 is relatively small (mainly the weight of the climbing basket 51 and personnel / tools), therefore its slewing bearing and drive device are smaller, focusing more on achieving lightweight and flexible micro-motion control. Further details will not be provided here.

[0040] In one embodiment of the present invention, at least one pair of anti-collision mechanisms are symmetrically arranged on both sides of the suspended basket 52; Each anti-collision stabilization mechanism includes a linear actuator 81, a connecting rod 82, and an adsorption assembly 83. The linear actuator 81 is horizontally positioned and fixedly installed on the side of the suspended basket 52, and its driving end is drivenly connected to the connecting rod 82. The connecting rod 82 extends vertically, and the adsorption assembly 83 is installed on the connecting rod 82. The linear actuator 81 is used to drive the connecting rod 82 and the adsorption assembly 83 to reciprocate in the horizontal direction so that the adsorption assembly 83 contacts or moves away from the working wall surface.

[0041] It should be noted that the anti-collision mechanisms symmetrically arranged on both sides of the suspended platform 52 are safety and stability devices specifically designed for deep pit or vertical sidewall working environments. This mechanism provides horizontal driving force through a linear actuator 81 (such as an electric push rod or hydraulic cylinder), driving the connecting rod 82 and the adsorption assembly 83 to extend towards the working wall. When the adsorption assembly 83 (usually a vacuum suction cup assembly) contacts the wall, the vacuum system is activated to firmly adsorb it, thus physically connecting the suspended platform 52 to the robust working structure into a temporary whole. Actively eliminating swaying, the rigid or semi-rigid connection suppresses the swaying of the suspended platform 52 caused by personnel movement, equipment operation, or wind, providing stability for deep pit operations. Simultaneously, as the suspended platform 52 approaches the wall, this mechanism acts as a buffer and guide, preventing hard collisions between the suspended platform 52 and the wall, and assisting in stabilizing the suspended platform 52 at a preset working distance, achieving soft contact. This ensures the suspended platform 52 is force-balanced and can adapt to working surfaces at different angles.

[0042] In one embodiment of the present invention, the adsorption component 83 includes a plurality of vacuum suction cups, which are uniformly arranged along the length of the connecting rod 82.

[0043] In one embodiment of the present invention, a control system is also included. The control system is connected to the slewing drive 12, the drive assembly and the leveling mechanism, and is equipped with a ground control console and an operation control console that can switch control permissions.

[0044] It should be noted that the ground control console and the work control console, which allow switching of control permissions and establish interlocking logic (such as automatically locking the lower control when the upper control is activated), constitute a management mechanism to ensure operational safety. This avoids the risk of misoperation caused by signal interference or accidental touches by personnel, which may occur with traditional equipment. It ensures that when working in the deep pit of the suspended platform 52 or at height in the elevated platform 51, control is always in the hands of the operator who is closest to the work site and has the best view, thus guaranteeing safe and high-quality operations.

[0045] When lowering the suspended platform 52 in deep pit mode, the control system can synchronously coordinate the slight rotation of the slewing drive component 12 to avoid obstacles and monitor the status of the leveling mechanism in real time. In high-altitude mode, it ensures that the leveling mechanism acts first to keep the elevated platform 51 horizontal before allowing the folding arm assembly to make large-scale changes in amplitude. This intelligent control enables multiple originally independent and complex mechanical actions to be performed smoothly, synchronously, and safely, simplifying the operation and lowering the barrier to entry.

[0046] In summary, this invention creatively integrates the traditionally separate functions of an aerial work platform and a deep-pit work scaffold into a unified device that can quickly switch between operating modes, by combining a highly mobile tracked chassis 11 and a multi-degree-of-freedom articulated boom assembly. This achieves dual functionality in one machine. It solves the systemic problems of difficulty in accessing the site, complex coordination, low efficiency, and high costs caused by relying on multiple single-function devices in narrow and complex construction environments. It provides an efficient, economical, and safe comprehensive solution for maintenance and repair work in special scenarios such as large-scale water conservancy projects.

[0047] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
