[0001] The present invention relates to the technical field of building platforms, and in particular to a multi-dimensionally adjustable hydraulic building platform device and a method for using the same. Background Art

[0002] In fields such as construction, industrial assembly, and logistics warehousing, adjustable platforms are essential for high-altitude operations, precision positioning, and heavy-load handling. Currently, common platform devices on the market primarily achieve single- or dual-dimensional adjustment through mechanical screws, electric guide rails, or pneumatic drives. Lifting platforms are widely used. Existing lifting platforms generally rely on mechanical screws or pneumatic drives, resulting in large size, high clearance requirements, and limited single- or dual-dimensional adjustment, making them difficult to adapt to the assembly of unusually shaped workpieces and operations in confined spaces. Summary of the Invention

[0009] Furthermore, a universal wheel with a braking function is installed at the bottom of the base.

[0010] Furthermore, it also includes a controller, which is signal-connected to the lifting mechanism, the lateral moving mechanism and the first telescopic mechanism.

[0011] Furthermore, the controller adjusts the pitch angle or roll angle of the standing board by independently controlling the extension and retraction amounts of multiple groups of the first retractable mechanisms.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a communication between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0022] Example 1 like Figures 1-9 As shown, A multi-dimensionally adjustable hydraulic building platform device includes a base 1, a lifting mechanism 5 is provided on the top of which a top plate 3 is fixedly installed on the top of the lifting mechanism 5, a mounting plate 10 is slidably connected to the top plate 3 along its length direction, and a lateral moving mechanism 4 is provided on the top plate 3 for driving the mounting plate 10 to slide.

[0023] The mounting plate 10 is mounted on the standing plate 7. Multiple sets of first telescopic mechanisms 9 are installed on the mounting plate 10 to drive the multi-dimensional angle adjustment of the standing plate 7. These first telescopic mechanisms 9 are hinged to the standing plate 7 and the mounting plate 10, respectively. The multiple first telescopic mechanisms 9 are hinged in a ring-shaped pattern between the mounting plate 10 and the standing plate 7. The standing plate 7 and connecting rod assembly are made of carbon fiber reinforced polymer (CFRP), reducing weight by 30% while improving rigidity.

[0024] A controller 11 is mounted on the base 1. Specifically, controller 11 sends signals to the lifting mechanism 5, driving the top plate 3 to rise or fall, adjusting the platform height. The horizontal position is adjusted by the lateral movement mechanism 4, which drives the mounting plate 10 to slide along the length of the top plate 3. Multiple sets of annularly distributed first telescopic mechanisms 9, through different telescopic strokes (e.g., extension of the front telescopic mechanism and shortening of the rear telescopic mechanism), cause the standing plate 7 to produce pitch or roll angle changes. This hydraulically driven, multi-dimensional adjustment allows for complex working postures within a confined space. The angle adjustment range is wider and there are no mechanical dead zones, making it suitable for assembling special-shaped workpieces, thereby enhancing the versatility of the device.

[0025] In this embodiment, the angle adjustment accuracy and feedback control of the standing board 7 can be increased. A high-precision MEMS tilt sensor is integrated at the bottom of the standing board 7 to provide real-time feedback of the pitch / roll angle to the controller 11 to achieve closed-loop control (e.g., ±0.1° accuracy).

[0026] In this embodiment, the first telescopic mechanism 9 is provided with a hydraulic cylinder displacement monitoring mechanism. By adding a linear displacement sensor (LVDT) to the first telescopic mechanism 9, the telescopic amount of each push rod is accurately controlled to avoid distortion of the standing board caused by asynchronous multi-cylinder movement.

[0027] In this embodiment, if Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the lifting mechanism 5 includes a bottom frame 51, a top frame 56 is provided on the top of the bottom frame 51, and two groups of connecting rod assemblies are relatively hinged between the bottom frame 51 and the top frame 56. Each group of connecting rod assemblies includes a first connecting rod 52 and a second connecting rod 53 that are relatively crossed and movably connected. One end of the first connecting rod 52 is rotatably set on the top frame 56, and the other end is slidably set on the bottom frame 51. One end of the second connecting rod 53 is rotatably set on the bottom frame 51, and the other end is slidably set on the top frame 56. A connecting plate 55 is mounted on the two first connecting rods 52. A second telescopic mechanism 54, whose other end is hinged to the connecting plate 55, is hinged on the bottom frame 51. The second telescopic mechanism 54 is signal-connected to the controller 11. Specifically, the second telescopic mechanism 54 extends and retracts to push the connecting plate 55, driving the crossed first and second connecting rods 52, 53 to rotate. The sliding ends of the first and second connecting rods 52, 53 slide on the bottom frame 51 and the top frame 56, respectively, to achieve smooth raising and lowering of the top plate 3. The cross-link mechanism is smaller in size when retracted, making it suitable for use in indoor spaces with low ceilings.

[0028] In this embodiment, two sets of second telescopic mechanisms 54 are symmetrically arranged within the cross-link mechanism, enhancing lifting stability and distributing the load. A tungsten carbide coating is laser-clad on the sliding ends of the first link 52 and second link 53 (the interface between the bottom frame 51 and the top frame 56) to extend service life.

[0029] In this embodiment, if Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the transverse movement mechanism 4 includes a threaded rod 43 and multiple first sliders 42, which are rotatably mounted on the top plate 3. The threaded rod 43 extends through and is threadedly connected to the mounting plate 10. A motor 41 is fixedly mounted on the top plate 3 to drive the threaded rod 43. The motor 41 is a servo motor and is signal-connected to the controller 11. The multiple first sliders 42 are relatively fixedly mounted on the bottom of the mounting plate 10. The top plate 3 is provided with a slide rail 44 for the first sliders 42 to slide. Specifically, the motor 41 is activated by the controller 11, driving the threaded rod 43 to rotate. The mounting plate 10 moves linearly along the threaded rod 43 through threaded engagement, and the first sliders 42 are guided on the slide rail 44.

[0030] In this embodiment, if Figure 1 、 Figure 2 、 Figure 3 、 Figure 8 and Figure 9 As shown, the structure further includes a staircase assembly 6 comprising an upper staircase 62 and a lower staircase 61 that are slidably connected to each other. The upper staircase 62 and the lower staircase 61 are fixedly connected to the top plate 3 and the base 1, respectively. The upper staircase 62 is fixedly mounted with a second slider 12, and the lower staircase 61 is provided with a slide groove 13 for the sliding of the second slider 12. Specifically, the length of the staircase assembly 6 automatically adjusts with the platform height, maintaining connectivity between the ground and the standing plate 7. The staircase can be adapted to different heights without disassembly, avoiding the additional space occupied by traditional fixed staircases. This makes it particularly suitable for frequent height switching operations between warehouse shelves.

[0031] In this embodiment, if Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 7 As shown, multiple sets of guardrails 8 are fixedly mounted along the perimeter of the standing platform 7. The operator stands within the area enclosed by the guardrails 8, which prevent accidental falls. In this embodiment, the fixed guardrails 8 can be configured as a motorized folding structure, automatically adjusting their height as the platform tilts, ensuring the operator remains within the protective area. Infrared or ultrasonic sensors embedded in the edges of the guardrails 8 immediately lock the platform's movement and sound an alarm if a person crosses the boundary.

[0032] In this embodiment, if Figure 1 、 Figure 2 and Figure 3 As shown, multiple sets of universal wheels 2 with braking functions are fixedly installed at the bottom of the base 1, and the universal wheels 2 facilitate the movement of the device.

[0033] Both the first telescopic mechanism 9 and the second telescopic mechanism 54 are electrically controlled hydraulic push rods. Pitch angle adjustment is achieved by differentially controlling the extension and retraction of the first telescopic mechanisms on the front and rear sides of the standing platform. Conventional hydraulic pushers primarily comprise a fuel tank, a hydraulic pump, and a hydraulic cylinder. When the hydraulic pusher is energized, the oil stored in the tank is pumped into the hydraulic cylinder by the hydraulic pump. As the oil pressure in the cylinder gradually increases, the oil pushes the piston, causing the push rod on the piston to extend upward. Furthermore, in this embodiment, the electrically controlled hydraulic push rods feature dynamic load adaptation. Pressure sensors are added to the hydraulic circuit to monitor the load pressure of each first telescopic mechanism 9 in real time. When the standing platform 7 is unevenly loaded, the oil flow distribution is automatically adjusted to prevent unilateral overload. A proportional valve is integrated into the hydraulic push rods, and the damping coefficient is dynamically adjusted by the controller 11 to suppress platform shaking caused by external impacts (such as assembly vibration).

[0034] The working principle of the present invention is as follows: the lifting mechanism 5 adopts a cross-link structure, and the second telescopic mechanism 54 pushes the connecting plate 55 to make the sliding ends of the first connecting rod 52 / the second connecting rod 53 move on the bottom frame 51 / the top frame 56, so as to achieve smooth lifting and lowering of the top plate 3; The motor 41 drives the threaded rod 43 to rotate, driving the mounting plate 10 to move along the slide rail 44 via the first slider 42; Multiple groups of hydraulic first telescopic mechanisms 9 distributed in an annular manner are differentially extended and retracted to make the standing board 7 pitch / roll ±15°; The upper staircase 62 slides in the slide groove 13 of the lower staircase 61 through the second slider 12 to achieve synchronous height expansion and contraction; The controller 11 coordinates the actions of various mechanisms.

[0035] When the present invention is used: Start the controller 11 and adjust the platform height through the second telescopic mechanism 54. The controller pushes the connecting plate 55 by extending and retracting the second telescopic mechanism 54, thereby driving the crossed first connecting rod 52 and the second connecting rod 53 to rotate. The sliding ends of the first connecting rod 52 and the second connecting rod 53 slide on the bottom frame 51 and the top frame 56 respectively, thereby achieving a smooth lifting and lowering of the top plate 3, driving the top plate 3 to rise or fall, and adjusting the platform height. The motor 41 drives the mounting plate 10 to the target horizontal position. The motor 41 drives the threaded rod 43 to rotate, and the mounting plate 10 moves linearly along the threaded rod 43 through thread engagement to achieve horizontal position adjustment; Control the designated first telescopic mechanism 9 groups to extend and retract, so that the standing plate 7 is tilted to adapt to the surface of the workpiece; through the extension and retraction of multiple groups of annularly distributed first telescopic mechanisms 9 with different strokes (such as extension of the front telescopic mechanism and shortening of the rear telescopic mechanism), the standing plate 7 produces pitch or roll angle changes. Through hydraulically driven multi-dimensional adjustment, complex working postures can be achieved in a limited space. The angle adjustment range is larger and there is no mechanical dead zone, which is suitable for the assembly of special-shaped workpieces, thereby improving the versatility of the device.

[0036] At the same time, during the adjustment process, the stair assembly 6 automatically extends to form a safe passage.

[0037] The present invention uses a lifting mechanism to drive the top plate up or down to adjust the platform height. A transverse movement mechanism drives the mounting plate to slide along the length of the top plate to achieve horizontal position adjustment. Multiple sets of annularly distributed first telescopic mechanisms, through different strokes of telescoping, cause the standing plate to produce pitch or roll angle changes. Hydraulically driven multi-dimensional adjustment enables complex operating postures within a limited space. The angle adjustment range is wider and there are no mechanical dead zones, making it suitable for assembling special-shaped workpieces, thereby improving the versatility of the device. The length of the staircase assembly of the present invention automatically adjusts with the platform height, maintaining connectivity between the ground and the standing plate. The staircase can adapt to different heights without disassembly, avoiding the extra space occupied by traditional fixed staircases. The staircase is particularly suitable for frequent height switching operations between warehouse shelves.

[0038] The annular hydraulic mechanism of the present invention realizes angle adjustment without dead zone, which is suitable for curved surface assembly; the retracted height of the cross-link lifting mechanism is reduced by 40%, which is suitable for a space with a floor height of 2.5m; the integrated staircase assembly eliminates the need for disassembly and improves storage operation efficiency.

[0039] The differential extension and retraction of the hydraulically driven first telescopic mechanism of the present invention causes the standing board to produce pitch / roll angle changes. Combined with the vertical stroke of the lifting mechanism and the horizontal displacement of the lateral moving mechanism, five-degree-of-freedom adjustment capabilities in three-dimensional space and two-axis angles are formed, which meets the positioning requirements of assembly of special-shaped curved workpieces and realizes multi-dimensional precision adjustment; the retracted height of the cross-link lifting mechanism of the present invention is lower than that of the traditional scissors-type, and with the integrated translation design, the working spacing of the device can enter narrow scenes such as shelf aisles and ship cabins; multi-dimensional adjustments are centrally coordinated by a single controller, eliminating the need for manual repeated positioning links, and the time spent on complex posture adjustments is effectively reduced.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
