[0002] With the continuous development of aerial work equipment, rotating suspended platform devices, as an important construction tool, are widely used in construction of building exterior walls, equipment installation and maintenance and other operation scenarios.

[0003] The rotating suspended platform device in the related technology (such as CN104847100B) connects the L-shaped anchor plate fixed on the vertical wall to the cantilever beam through the screw. The cantilever beam can rotate at multiple angles around the screw, realizing multi-angle coverage of the suspended platform at the corner of the narrow column structure, and meeting the needs of different working surfaces in high-altitude operations.

[0004] However, the rotating suspended platform device in the related technology has poor flexibility in adjusting the angle of the suspended platform, resulting in poor applicability and ease of operation in complex construction scenarios. Utility Model Content

[0005] Therefore, it is necessary to provide a rotating suspended platform device to address the problem that the rotating suspended platform in the relevant technology has poor flexibility in adjusting the angle of the suspended platform, resulting in poor applicability and ease of operation in complex construction scenarios.

[0010] The first hydraulic telescopic rod has one end rotatably connected to the rotary table about the axis of the second direction;

[0011] A second drive mechanism connected to the rotary table is used to drive the first hydraulic telescopic rod to rotate;

[0012] The first connecting rod has one end rotatably connected to the end of the first hydraulic telescopic rod away from the rotary table about an axis in a second direction, which is perpendicular to the first direction.

[0013] A third drive mechanism connected to the first hydraulic telescopic rod is used to drive the first connecting rod to rotate;

[0014] The fourth drive mechanism is connected to the end of the first link away from the first hydraulic telescopic rod; and

[0015] The suspended platform connected to the fourth drive mechanism can rotate relative to the first link under the drive of the fourth drive mechanism. The axis of rotation of the suspended platform relative to the first link is perpendicular to the length direction of the first link.

[0016] In some embodiments, the fourth drive mechanism includes: a housing, a first motor, a first gear transmission assembly, and a main shaft;

[0017] Both the first motor and the first gear transmission assembly are located inside the housing, and the first motor is connected to the main shaft through the first gear transmission assembly.

[0018] The main shaft is rotatably connected via a bearing housing, with one end of the main shaft extending out of the housing and fixedly connected to the suspended platform.

[0019] In some embodiments, the fourth drive mechanism further includes an annular support platform, which is sleeved and fixed to the main shaft. An annular groove is provided at one end of the annular support platform facing the suspended platform, and the central axis of the annular groove coincides with the central axis of the main shaft.

[0020] An annular bearing bracket is installed inside the annular groove, and universal balls are installed inside the annular bearing bracket. The universal balls abut against and roll with the inner surface of the outer shell.

[0021] In some embodiments, the fourth drive mechanism further includes:

[0022] The adjusting stud has its central axis perpendicular to the central axis of the main shaft. The adjusting stud is threaded to the side wall of the housing. One end of the adjusting stud is located inside the housing, and the other end is located outside the housing.

[0023] The guide rod is fixed to the inner side of the housing, and its central axis is parallel to the central axis of the adjusting stud; and

[0024] The brake pads are rotatably connected to one end of the adjusting stud that extends into the housing via a bearing. The brake pads are used to abut against the spindle to brake the spindle.

[0025] In some embodiments, the outer peripheral side of the spindle is provided with friction patterns, and the brake pad is opposite to and abuts against the friction patterns.

[0026] In some embodiments, the first drive mechanism is located inside the base and is connected to one end of the rotary table along a first direction;

[0027] A first hinge support is provided at the other end of the rotary table along the first direction, and one end of the first hydraulic telescopic rod is rotatably connected to the rotary table through the first hinge support.

[0028] In some embodiments, the first hydraulic telescopic rod is a multi-stage hydraulic telescopic rod.

[0029] In some embodiments, the second driving mechanism is a second hydraulic telescopic rod, one end of which is connected to the outer periphery of the rotary table, and the other end is connected to the first hydraulic telescopic rod.

[0030] In some embodiments, the third driving mechanism is a third hydraulic telescopic rod, one end of which is connected to the first hydraulic telescopic rod and the other end of which is connected to the first connecting rod.

[0031] In some embodiments, a battery box is provided on the suspended platform, and a rechargeable battery pack is installed inside the battery box.

[0032] In actual use, the aforementioned rotating suspended platform device utilizes a first drive mechanism to drive the rotating platform to rotate relative to the base around an axis in a first direction, thereby causing the suspended platform to rotate along a circular trajectory around the first (vertical) axis. A second drive mechanism drives the first hydraulic telescopic rod to rotate relative to the rotating platform around an axis in a second direction, allowing the suspended platform to rotate in the pitch direction along the first hydraulic telescopic rod around the second (horizontal) axis. Furthermore, a third drive mechanism drives the first connecting rod to rotate relative to the first hydraulic telescopic rod around an axis in the second direction, ensuring that the bottom support plate of the suspended platform remains horizontal, guaranteeing stable operation for construction personnel. Adjusting the extension length of the first hydraulic telescopic rod allows for adjustment of the suspended platform's position along a direction parallel to its length. A fourth drive mechanism drives the suspended platform to rotate relative to the first connecting rod, further adjusting the angle of the suspended platform relative to the first connecting rod. In this way, the suspended platform can be adjusted at multiple rotation centers. The rotating table can rotate 100 degrees, thus driving the suspended platform to rotate 100 degrees along a circular trajectory. When the fourth drive mechanism drives the suspended platform to rotate relative to the first link, the suspended platform can rotate 100 degrees, making the angle adjustment of the suspended platform highly flexible and the rotation range comprehensive. Furthermore, it ensures that the bottom support plate of the suspended platform always remains horizontal, guaranteeing stable operation for construction personnel. Thus, in complex construction scenarios, the aforementioned rotating suspended platform can be easily and flexibly adjusted to various construction positions, thereby improving the ease of operation for construction personnel and the applicability of the rotating suspended platform in complex construction environments.

[0045] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0046] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and 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, and therefore should not be construed as a limitation of this application.

[0047] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0048] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0049] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0050] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0051] As mentioned in the background section, the rotating suspended platform devices in related technologies (such as CN104847100B) have poor flexibility in adjusting the angle of the suspended platform working platform, resulting in poor applicability and ease of operation in complex construction scenarios. The inventors have discovered that the main reason for this is that in the rotating suspended platform devices of related technologies, the suspended platform working platform can only rotate with the cantilever beam, that is, it can only rotate around the screw as the center of rotation, the center of rotation is fixed, and the rotation range is less than 360 degrees.

[0052] For complex construction scenarios, highly flexible adjustments to the angle of the suspended platform are required, such as in the construction of irregularly shaped building facades, bridge maintenance, and wind turbine blade maintenance. In the case of irregularly shaped building facades, such as those of spherical stadiums or spiral towers, the suspended platform needs to continuously traverse various points along the curved surface of the facade during construction. In bridge maintenance scenarios, the angle of the suspended platform needs to be flexibly adjusted to avoid steel cable obstacles and work close to the bridge piers. In wind turbine blade maintenance scenarios, multi-angle positioning of the suspended platform is required within the confined space of the nacelle platform.

[0053] If the conventional rotating suspended platform device described above is applied to complex construction scenarios, the platform's poor flexibility in adjusting its angle makes it difficult to adjust to different construction positions. This results in poor ease of operation for construction workers on the platform, meaning that conventional rotating suspended platform devices are not well-suited for complex construction scenarios.

[0054] Please combine Figure 1 and Figure 2 One embodiment of this application provides a rotating suspended platform device, which includes: a base 100, a rotating table 200, a first drive mechanism 110, a first hydraulic telescopic rod 300, a second drive mechanism 310, a first connecting rod 400, a third drive mechanism 410, a fourth drive mechanism 500, and a suspended platform 600.

[0055] The rotary table 200 and the base 100 are rotatably connected about an axis in a first direction. Specifically, the rotary table 200 and the base 100 can be rotatably connected via bearings. The central axis of the rotary table 200 coincides with the central axis of the base 100.

[0056] A first drive mechanism 110 is disposed on the base 100 and connected to the rotary table 200, and is used to drive the rotary table 200 to rotate, thereby enabling the rotary table 200 to rotate relative to the base 100 about an axis in a first direction. The axis of rotation of the rotary table 200 relative to the base 100 coincides with its central axis. The rotary table 200 is capable of rotating 360 degrees relative to the base 100 about the axis in the first direction.

[0057] One end of the first hydraulic telescopic rod 300 is rotatably connected to the rotary table 200 about the axis in the second direction.

[0058] The second drive mechanism 310 is connected to the rotary table 200 and the first hydraulic telescopic rod 300, and is used to drive the first hydraulic telescopic rod 300 to rotate, thereby enabling the first hydraulic telescopic rod 300 to rotate relative to the rotary table 200 about an axis in a second direction. Figure 1 As shown, the first hydraulic telescopic rod 300 can rotate to a state tilted in the first direction.

[0059] One end of the first connecting rod 400 is rotatably connected to the end of the first hydraulic telescopic rod 300 away from the rotary table 200 about the axis of the second direction, which is perpendicular to the first direction.

[0060] Specifically, one end of the first connecting rod 400 and the end of the first hydraulic telescopic rod 300 away from the rotary table 200 can be rotatably connected by a hinge support.

[0061] The third drive mechanism 410 is connected to the first hydraulic telescopic rod 300 and the first connecting rod 400, and is used to drive the first connecting rod 400 to rotate, thereby enabling the first connecting rod 400 to rotate relative to the first hydraulic telescopic rod 300 about an axis in a second direction. Figure 1 As shown, by rotating the first link 400 relative to the first hydraulic telescopic rod 300 about the axis in the second direction, the length direction of the first link 400 can be positioned in the third direction. This third direction is perpendicular to both the first and second directions.

[0062] In actual use, the rotating suspended platform device has the first direction along the vertical direction, the second direction along the horizontal direction, and the third direction along the horizontal direction.

[0063] The fourth drive mechanism 500 is connected to the end of the first connecting rod 400 away from the first hydraulic telescopic rod 300, and is also connected to the suspended platform 600. The fourth drive mechanism 500 drives the suspended platform 600 to rotate 360 ​​degrees relative to the first connecting rod 400. The suspended platform 600 can rotate relative to the first connecting rod 400 under the driving action of the fourth drive mechanism 500. The axis of rotation of the suspended platform 600 relative to the first connecting rod 400 is perpendicular to the length direction of the first connecting rod 400.

[0064] In actual use, the base 100 of the aforementioned rotating suspended platform serves as the bottom support for the entire rotating suspended platform and can be fixed to the top of a building, a support frame, or a mobile trolley platform, etc.

[0065] The first drive mechanism 110 drives the rotary table 200 to rotate relative to the base 100 around the axis of the first direction. Thus, the rotary table 200 can drive the first hydraulic telescopic rod 300, the first connecting rod 400, the fourth drive mechanism 500, and the suspended platform 600 to rotate around the axis of the first direction. That is, the suspended platform 600 can rotate around the axis of the first direction (vertical direction) along a circular trajectory.

[0066] The first hydraulic telescopic rod 300 is driven by the second drive mechanism 310 to rotate relative to the rotary table 200 around the axis of the second direction. As a result, the end of the first hydraulic telescopic rod 300 away from the rotary table 200 can make pitching motion around the axis of the second direction (horizontal direction). Consequently, the first connecting rod 400, the fourth drive mechanism 500 and the suspended platform 600 can rotate in the pitching direction with the first hydraulic telescopic rod 300 around the axis of the second direction (horizontal direction).

[0067] Understandably, after the first link 400, the fourth drive mechanism 500, and the suspended platform 600 rotate in the pitch direction with the first hydraulic telescopic rod 300 around the second direction (horizontal direction) axis, the length direction of the first link 400 may tilt to the horizontal direction, and the bottom support plate of the suspended platform 600 may also tilt to the horizontal direction. Therefore, in this embodiment, the first link 400 is driven to rotate relative to the first hydraulic telescopic rod 300 around the second direction axis by the third drive mechanism 410. This adjusts the length direction of the first link 400 to remain in the third direction (horizontal direction), and the bottom support plate of the suspended platform 600 can also remain in the horizontal direction, allowing construction personnel to work stably on the suspended platform 600. In other words, it ensures that while the suspended platform 600 rotates in the pitch direction with the first hydraulic telescopic rod 300 around the second direction (horizontal direction) axis, the bottom support plate of the suspended platform 600 remains in the horizontal direction.

[0068] Meanwhile, by adjusting the extension length of the first hydraulic telescopic rod 300, the position of the suspended platform 600 can be adjusted in a direction parallel to the length of the first hydraulic telescopic rod 300.

[0069] When the length direction of the first link 400 is along the third direction, the fourth drive mechanism 500 can drive the suspended platform 600 to rotate 360 ​​degrees relative to the first link 400 around the axis of the first direction, thereby further adjusting the angle of the suspended platform 600 relative to the first link 400 around the axis of the first direction.

[0070] In actual use, the aforementioned rotating suspended platform device drives the rotating platform 200 to rotate relative to the base 100 around an axis in a first direction via the first drive mechanism 110, which in turn drives the suspended platform 600 to rotate along a circular trajectory around the axis in the first direction (vertical direction). The first hydraulic telescopic rod 300 is driven to rotate relative to the rotating platform 200 around an axis in a second direction via the second drive mechanism 310, allowing the suspended platform 600 to rotate in the pitch direction along with the first hydraulic telescopic rod 300 around the axis in the second direction (horizontal direction). Furthermore, the first connecting rod 400 is driven to rotate relative to the first hydraulic telescopic rod 300 around an axis in the second direction via the third drive mechanism 410, ensuring that the bottom support plate of the suspended platform 600 remains horizontal, guaranteeing stable operation for construction personnel on the suspended platform 600. By adjusting the extension length of the first hydraulic telescopic rod 300, the position of the suspended platform 600 can be adjusted in a direction parallel to the length of the first hydraulic telescopic rod 300. The fourth drive mechanism 500 drives the suspended platform 600 to rotate relative to the first link 400, which can further adjust the angle of the suspended platform 600 relative to the first link 400.

[0071] The aforementioned rotating suspended platform device allows the suspended platform 600 to adjust its angle around multiple rotation centers. The rotating table 200 can rotate 360 ​​degrees, thus driving the suspended platform 600 to rotate 360 ​​degrees along a circular trajectory. When the fourth drive mechanism 500 drives the suspended platform 600 to rotate relative to the first connecting rod 400, the suspended platform 600 can rotate 360 ​​degrees, resulting in highly flexible angle adjustment and a comprehensive rotation range. Furthermore, it ensures that the bottom support plate of the suspended platform 600 remains horizontal, guaranteeing stable operation for construction personnel. Therefore, in complex construction scenarios, the suspended platform can be easily and flexibly adjusted to various construction positions, improving the ease of operation for construction personnel and the applicability of the rotating suspended platform device in complex construction environments.

[0072] Please combine Figure 3 and Figure 4 In some embodiments, the fourth drive mechanism 500 includes: a housing 510, a first motor 520, a first gear transmission assembly 530, and a main shaft 540.

[0073] The first motor 520 and the first gear transmission assembly 530 are both located inside the housing 510, and the first motor 520 is connected to the main shaft 540 through the first gear transmission assembly 530.

[0074] The main shaft 540 is rotatably connected to the housing 510 via a bearing (which may be a thrust bearing), and one end of the main shaft 540 extends out of the housing 510 and is fixedly connected to the suspended platform 600.

[0075] Specifically, the outer shell 510 is a cylindrical shell, which can be a cylindrical, square prism, or other cylindrical shells. The central axis of the outer shell 510 coincides with the central axis of the main shaft 540.

[0076] The outer casing 510 can be fixedly connected to the end of the first connecting rod 400 away from the first hydraulic telescopic rod 300 via a connector.

[0077] The first motor 520 can be a stepper motor. The first motor 520 is installed inside the housing 510.

[0078] The rotation axis of the main shaft 540 is aligned with its own central axis. The suspended platform 600 is fixedly connected to the main shaft 540, thus enabling them to rotate synchronously.

[0079] Optionally, the first gear transmission assembly 530 includes a first gear 531 and a second gear 532. The first gear 531 is coaxially connected to the main shaft 540, and the second gear 532 is coaxially connected to the output shaft of the first motor 520. The first gear 531 and the second gear 532 mesh. Thus, when the second gear 532 rotates with the output shaft of the first motor 520, it can drive the meshed first gear 531 to rotate, thereby causing the main shaft 540 and the first gear 531 to rotate synchronously.

[0080] In this embodiment, the first motor 520 drives the first gear transmission assembly 530 to move, thereby enabling the first gear transmission assembly 530 to drive the main shaft 540 to rotate, and the main shaft 540 to drive the suspended platform 600 to rotate. The fourth drive mechanism 500 in this embodiment has a simple structure and is convenient for driving the suspended platform 600 to rotate.

[0081] Please combine Figure 3 and Figure 4 In some embodiments, the fourth drive mechanism 500 further includes an annular support platform 550, which is sleeved and fixed to the main shaft 540. The annular support platform 550 has an annular groove at one end facing the suspended platform 600, and the central axis of the annular groove coincides with the central axis of the main shaft 540.

[0082] An annular bearing bracket is installed in the annular groove, and a universal ball bearing 560 is installed in the annular bearing bracket. The universal ball bearing 560 abuts against and rolls with the inner surface of the housing 510.

[0083] Specifically, the central axis of the annular groove coincides with the central axis of the annular bearing bracket, and multiple universal balls 560 are arranged sequentially along the circumference of the annular bearing bracket. Each universal ball 560 can rotate freely around its own center on the annular bearing bracket.

[0084] As the suspended platform 600 rotates with the main shaft 540, the weight of the suspended platform 600 acts on the main shaft 540, which in turn acts on the inner surface of the outer casing 510 through the main shaft 540, the annular support platform 550, and the universal ball bearings 560. Understandably, when the length of the first connecting rod 400 is along a third direction (horizontal), the axial direction of the main shaft 540 is along a first direction (vertical). Therefore, the weight of the suspended platform 600 acts on the bottom wall of the outer casing 510 through the main shaft 540, the annular support platform 550, and the universal ball bearings 560. This enhances the support strength of the suspended platform 600. Furthermore, during the rotation of the main shaft 540 relative to the outer casing 510, the rolling contact between the universal ball bearings 560 and the inner surface of the outer casing 510 allows the annular support platform 550 and the main shaft 540 to rotate smoothly, reducing rotational resistance.

[0085] Please combine Figure 3 and Figure 4 In some embodiments, the fourth drive mechanism 500 further includes an adjusting stud 570, a guide rod 580, and a brake pad 590. The central axis of the adjusting stud 570 is perpendicular to the central axis of the main shaft 540. The adjusting stud 570 is threadedly connected to the side wall of the housing 510, with one end of the adjusting stud 570 located inside the housing 510 and the other end located outside the housing 510. The guide rod 580 is fixed to the inner side of the housing 510, and the central axis of the guide rod 580 is parallel to the central axis of the adjusting stud 570. The brake pad 590 is rotatably connected to the end of the adjusting stud 570 that extends into the housing 510 via a bearing. The brake pad 590 is used to abut against the main shaft 540 to brake the main shaft 540.

[0086] When braking of the main shaft 540 is required, the operator can rotate the adjusting stud 570, which extends out of the housing 510, and use the threaded drive to push the adjusting stud 570 into the housing 510, thereby moving the brake pad 590 closer to the main shaft 540. Due to the engagement of the guide rod 580 and the brake pad 590, the brake pad 590 cannot rotate with the adjusting stud 570, but can only move along the guide rod 580. This allows the brake pad 590 to abut against the main shaft 540 when it reaches the main shaft, using friction to prevent the main shaft 540 from continuing to rotate. Conversely, rotating the adjusting stud 570 in the opposite direction will move the brake pad 590 away from the main shaft 540, releasing the braking of the main shaft 540.

[0087] During construction, if the suspended platform 600 needs to be adjusted to a specific angle to maintain stability (such as when construction workers are working or passing tools), the brake pads 590 of this embodiment can be used to brake the main shaft 540 to stabilize the angle of the suspended platform 600. Additionally, in case of dangerous situations such as strong winds or abnormal vibrations at the construction site, the brake pads 590 of this embodiment can also be used to brake the main shaft 540 to stabilize the angle of the suspended platform 600, thereby ensuring construction safety.

[0088] Please refer to Figure 4 In one embodiment, the outer peripheral side of the spindle 540 is provided with friction texture 541, and the brake pad 590 is opposite to the friction texture 541 and is used to abut against the friction texture 541.

[0089] In this embodiment, the friction texture 541 of the main shaft 540 can significantly increase the surface roughness of its outer periphery. When the brake pad 590 comes into contact with the friction texture 541, it can quickly brake the main shaft 540 through the friction texture 541, further improving the reliability of the braking structure and the safety of construction.

[0090] Please refer to Figure 3 In some embodiments, the first drive mechanism 110 is located inside the base 100 and is connected to one end of the rotary table 200 along a first direction.

[0091] A first hinge support 210 is provided at the other end of the rotary table 200 along the first direction, and one end of the first hydraulic telescopic rod 300 is rotatably connected to the rotary table 200 through the first hinge support 210.

[0092] In this embodiment, the first drive mechanism 110 is located inside the base 100, which can protect the service life of the first drive mechanism 110 and facilitate the arrangement of the first drive mechanism 110.

[0093] Specifically, the first drive mechanism 110 includes a second motor 111 and a second gear transmission assembly 112. The second motor 111 can...

[0094] In this embodiment, the second motor 111 drives the second gear transmission assembly 112 to move, thereby enabling the second gear transmission assembly 112 to rotate the rotary table 200. The second gear transmission assembly 112 may include a third gear 1121 and a fourth gear 1122. The third gear 1121 is coaxially connected to the output shaft of the second motor 111. The fourth gear 1122 is coaxially connected to the rotary table 200. The third gear 1121 and the fourth gear 1122 mesh.

[0095] In one embodiment, the first hydraulic telescopic rod 300 is a multi-stage hydraulic telescopic rod.

[0096] In this embodiment, the first hydraulic telescopic rod 300 adopts a multi-stage hydraulic telescopic rod. This multi-stage hydraulic telescopic rod can achieve a telescopic stroke far exceeding the initial length by extending multiple stages sequentially, even with a relatively short initial length. This provides a long range of telescopic adjustment in complex construction scenarios, ensuring the suspended platform 600 can stably remain in different positions, while also allowing it to retract to a shorter length for storage, reducing the space occupied by the device and facilitating transportation and installation.

[0097] In one embodiment, the second drive mechanism 310 is a second hydraulic telescopic rod, one end of which is connected to the outer periphery of the rotary table 200, and the other end is connected to the first hydraulic telescopic rod 300.

[0098] Specifically, one end of the second hydraulic telescopic rod can be rotatably connected to the outer periphery of the rotary table 200 via a hinge support, and the other end can be rotatably connected to the first hydraulic telescopic rod 300 via a hinge support.

[0099] In this embodiment, the second driving mechanism 310 is set as the second hydraulic telescopic rod, and its two ends are respectively connected to the outer periphery of the rotary table 200 and the first hydraulic telescopic rod 300. Thus, the extension and retraction of the second hydraulic telescopic rod can be used to drive the first hydraulic telescopic rod 300 to rotate, which facilitates driving the first hydraulic telescopic rod 300.

[0100] In one embodiment, the third drive mechanism 410 is a third hydraulic telescopic rod, one end of which is connected to the first hydraulic telescopic rod 300, and the other end is connected to the first connecting rod 400.

[0101] Specifically, one end of the third hydraulic telescopic rod is rotatably connected to the first hydraulic telescopic rod 300 via a hinge support, and the other end is rotatably connected to the first connecting rod 400 via a hinge support.

[0102] In this embodiment, the third drive mechanism 410 is set as a third hydraulic telescopic rod, and its two ends are respectively connected to the first hydraulic telescopic rod 300 and the first connecting rod 400. Thus, the extension and retraction of the third hydraulic telescopic rod can be used to drive the first connecting rod 400 to rotate, which facilitates the driving of the first connecting rod 400.

[0103] Each of the aforementioned hydraulic telescopic rods (first hydraulic telescopic rod, second hydraulic telescopic rod, and third hydraulic telescopic rod) can be driven to extend or retract via a hydraulic system.

[0104] In one embodiment, a battery box 700 is provided on the suspended platform 600, and a rechargeable battery pack is installed inside the battery box 700. The battery pack can power motors (such as a first motor and a second motor) and hydraulic systems.

[0105] In one embodiment, the suspended platform 600 adopts an anti-slip grating base plate, and the anti-slip grating base plate is provided with detachable guardrails around its perimeter.

[0106] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0107] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
