[0014] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0015] Please also read Figure 1 and Figure 2 In one embodiment of the present application, an automatic lifting operation platform 100 is provided, and the operation platform 100 includes a pillar 10, a lifting shield 20, a lifting mechanism 30, an operation platform 40, and a multi-section hydraulic cylinder 50. The pillar 10 is used as a supporting structure of the entire operation platform 100, and is used to provide support for the lifting shield 20, the lifting mechanism 30, the operation platform 100, and the multi-section hydraulic cylinder 50. The lifting mechanism 30 is used to drive the lifting shield 20 and the operation platform 40 to perform lifting movements, and the multi-section hydraulic cylinder 50 assists the lifting mechanism 30 in driving the operation platform 40 to perform lifting movements.

[0016] Specifically, the pillar 10 is used to stand on the foundation. A stable foundation connection member or base may be provided at the bottom of the pillar 10 to ensure that the entire operating platform 100 does not tilt or move during operation. It is understandable that the pillar 10 may also be installed on other platforms.

[0017] The lifting shield 20 is disposed on the outside of the pillar 10, and is slidably connected to the pillar 10, and can be lifted and lowered along the pillar 10. As a supporting component of the operating platform 100, the lifting shield 20 can not only connect the operating table 40, but also protect the internal components (such as transmission components) of the pillar 10 from the external environment.

[0018] The lifting mechanism 30 includes a first reduction motor 31 and a first transmission assembly 32 . The first reduction motor 31 is connected to the lifting shield 20 via the first transmission assembly 32 to drive the lifting shield 20 to perform lifting motion along the support column 10 .

[0019] The first reduction motor 31 is the main driving force source for the lifting shield 20 to perform lifting and lowering movements. It can convert electrical energy into mechanical kinetic energy, reduce the speed and increase the torque output through a reducer (not shown). The first transmission assembly 32 includes any one of a chain, a gear set, and a screw, and is responsible for transmitting the rotational force generated by the first reduction motor 31 to the lifting shield 20, so that it rises or falls along the support 10.

[0020] The operating platform 40 is connected to the lifting shield 20 to perform lifting motion driven by the lifting shield 20. The operating platform 40 serves as a support platform for the operator, providing support and protection for the operator during the operation process.

[0021] The multi-section hydraulic cylinder 50 is installed on the support column 10 . The extension direction of the output shaft of the multi-section hydraulic cylinder 50 is the same as the extension direction of the support column 10 , and the output shaft of the multi-section hydraulic cylinder 50 is connected to the lifting cover 20 .

[0022] In one application scenario, when the load of the lifting mechanism 30 is large or in order to further increase the lifting speed of the lifting shield 20, the multi-section hydraulic cylinder 50 can assist the lifting mechanism 30, thereby providing additional support force for the lifting shield 20 and the operating platform 40 connected to the lifting shield 20.

[0023] In other application scenarios, when the lifting mechanism 30 mainly based on the electrical system fails, the operating platform 100 can also rely on the multi-section hydraulic cylinder 50 mainly based on the hydraulic system to drive the lifting shield 20 and the operating platform 40 connected to the lifting shield 20 to slowly return to the ground, thereby increasing the system reliability of the entire automatic lifting operating platform 100. At the same time, since the multi-section hydraulic cylinder 50 has multiple telescopic sections (not shown in the figure), it can more accurately adjust the lifting shield 20 and the operating platform 40 connected to the lifting shield 20 to the required height position.

[0024] In the above-mentioned automatic lifting operating platform 100, the lifting height of the lifting cover 20 and the operating platform 40 connected to the lifting cover 20 is adjusted by setting a first reduction motor 31 and a multi-section hydraulic cylinder 50 in combination, which can improve the stability of the operating platform 100 during the lifting process. At the same time, the multi-section hydraulic cylinder 50 can also provide safety measures for the operating platform 40, so that the operating platform 40 can remain stable during the lifting process, further improving the safety performance of the operator during operation.

[0025] Please also read Figure 2 and Figure 3 In one embodiment, the first transmission assembly 32 includes a rack 321 and a first gear 322. The rack 321 is disposed on the pillar 10, and its extension direction is the same as that of the pillar 10. The first gear 322 is connected to the output shaft of the first reduction motor 31, and the first gear 322 is meshed with the rack 321.

[0026] Specifically, the extension direction of the rack 321 is consistent with the extension direction of the pillar 10, which can ensure that a stable meshing surface can be provided for the lifting shield 20 in the entire lifting stroke range. The first gear 322 is directly connected to the output shaft of the first reduction motor 31, and drives the lifting shield 20 to move along the pillar 10 through meshing with the rack 321. Through the close fit between the first gear 322 and the rack 321, a smooth lifting action can be provided for the lifting shield 20, reducing the risk of impact and vibration of the lifting shield 20 during the lifting process, thereby improving the operating comfort of the operator.

[0027] In one embodiment, the first gear 322 includes any one of a spur gear and a helical gear, which is not limited herein.

[0028] In another embodiment, the rack 321 can be replaced by a chain (not shown). In this case, the chain can be connected to the lifting shield 20, and the first reduction motor 31 is connected to the pillar 10 and meshed with the first gear 322 through the chain, so that the lifting shield 20 can be lifted and lowered relative to the pillar 10.

[0029] In another embodiment, the first transmission assembly 32 includes a screw (not shown) and a nut (not shown), the screw is connected to the output shaft of the first reduction motor 31, and the nut matches the screw and is fixed on the lifting shield 20. When the screw rotates, the nut moves up and down along the screw, thereby driving the entire lifting shield 20 and the operating platform 40 to rise or fall.

[0030] Please continue reading Figure 2 and Figure 3 In one embodiment, a housing space 11 is provided inside the support column 10, and the multi-section hydraulic cylinder 50 is located in the housing space 11. The lifting shield 20 is sleeved on the periphery of the support column 10, and openings 12 communicating with the housing space 11 are provided on the two opposite side walls of the support column 10, and the output shaft of the multi-section hydraulic cylinder 50 is connected to the lifting shield 20 through a connecting bracket 51 passing through the opening 12. By placing the multi-section hydraulic cylinder 50 inside the support column 10 and connecting it to the lifting shield 20 through the opening 12 and the connecting bracket 51, not only can the space be effectively utilized, but also the stability and safety of the lifting shield 20 during the lifting process can be improved.

[0031] In one embodiment, two or more groups of multi-section hydraulic cylinders 50 may be disposed inside the pillar 10 to provide dual or multiple power supports for the lifting and lowering movement of the lifting shield 20 , thereby further improving the reliability and safety of the operating platform 100 .

[0032] In one embodiment, limit switches (not shown) may be provided at the top and bottom of the support 10 to automatically cut off the multi-section hydraulic cylinder 50 based on the hydraulic system when the lifting shield 20 reaches the limit position, thereby preventing the lifting shield 20 from exceeding the stroke and causing damage.

[0033] Please refer again Figure 1 and Figure 2 In one embodiment, the lifting shield 20 is sleeved on the periphery of the pillar 10, and the automatic lifting operation platform 100 further includes a first guide rail 60 and a first slider 70. The first guide rail 60 is provided on the pillar 10, and the extension direction of the first guide rail 60 is the same as the extension direction of the pillar 10. The first slider 70 is slidably provided on the first guide rail 60 and connected to the lifting shield 20. The lifting shield 20 can move along the first guide rail 60 synchronously with the first slider 70, reducing the risk of the lifting shield 20 deviating from the moving trajectory during the lifting movement.

[0034] In one embodiment, the lifting shield 20 is a frame or box covering the periphery of the support column 10 , which not only provides additional protection but also serves as a support base for other components (such as the operating platform 40 ).

[0035] In one embodiment, the first guide rail 60 includes any one of a V-shaped guide rail, a square rail, and a cylindrical guide rail, which is not limited herein.

[0036] In one embodiment, rolling elements such as balls (not shown) or rollers (not shown) may be provided inside the first slider 70. The balls or rollers are in contact with the first guide rail 60, which can reduce the friction between the first guide rail 60 and the first slider 70, thereby improving the operating efficiency of the lifting shield 20.

[0037] In one embodiment, the number of the first guide rails 60 and the first slider 70 may include multiple, and the multiple first guide rails 60 are respectively arranged on different sides of the pillar 10, and the first slider 70 is arranged one by one with the first guide rails 60, so as to further improve the stability of the lifting shield 20 during the lifting process.

[0038] See also Figure 1 In one embodiment, the lifting mechanism 30 also includes a first tank chain wiring groove 33, which is used to accommodate multiple cables and hoses during the lifting movement. By placing multiple cables and hoses in the first tank chain wiring groove 33 in an orderly manner, the working area near the lifting mechanism 30 can be made tidy and convenient for maintenance and troubleshooting.

[0039] See also Figure 4In one embodiment, the operating platform 40 includes a pedal 41 connected to the lifting shield 20, and the pedal 41 includes a fixed sub-pedal 411, a movable sub-pedal 412 and a translation mechanism 413. The fixed sub-pedal 411 is fixedly connected to the lifting shield 20, and the movable sub-pedal 412 is movably connected to the fixed sub-pedal 411, wherein an operation box 414 is installed on the movable sub-pedal 412. The translation mechanism 413 is used to drive the movable sub-pedal 412 to approach or move away from the fixed sub-pedal 411. Through the above arrangement, the movable sub-pedal 412 can provide a working space for the operator, and the fixed sub-pedal 411 supports the movable sub-pedal 412, so that the lifting shield 20 can drive the fixed sub-pedal 411 and the movable sub-pedal 412 connected to the fixed sub-pedal 411 to perform lifting and lowering movements. At the same time, the translation mechanism 413 drives the movable sub-pedal 412 to move relative to the fixed sub-pedal 411, thereby improving the flexibility of the operating platform 40 and further increasing the operator's workable range.

[0040] In one embodiment, the operating platform 40 also includes a limit switch (not shown) or a mechanical stop component (not shown), which is used to control the movable sub-pedal 412 to automatically stop when it reaches the maximum stroke, thereby preventing the pedal 41 from being damaged due to excessive extension and retraction.

[0041] In one embodiment, the surface of the movable sub-pedal 412 may be treated to prevent slipping, such as by laying an anti-slip mat (not shown) or adding texture to prevent the operator from slipping.

[0042] Please continue reading Figure 4 In one embodiment, the operating platform 40 further includes a protective fence 42, which is arranged around the pedal 41. In order to adapt to different working heights and task requirements of operators, a protective fence 42 with adjustable height can be installed on the operating platform 40 to enhance safety.

[0043] In one embodiment, the operating box 414 installed on the movable sub-pedal 412 may include a control panel, a power socket, a tool storage space, etc., to facilitate the operator to control the equipment and access tools.

[0044] Please continue reading Figure 4 In one embodiment, the translation mechanism 413 includes a second reduction motor 4131 and a second transmission assembly 4132. The second reduction motor 4131 drives the movable sub-pedal 412 to approach or move away from the fixed sub-pedal 411 through the second transmission assembly 4132. In the above configuration, the second reduction motor 4131 is the main power source of the translation mechanism 413. The motor output with high speed and low torque is converted into low speed and high torque power through a reducer (not shown), thereby realizing the requirement that the second transmission assembly 4132 drives the movable sub-pedal 412 to move relative to the fixed sub-pedal 411.

[0045] Please also read Figure 4 and Figure 5 In one embodiment, the second transmission assembly 4132 includes a transmission chain 4132A, a second gear 4132B and a guide wheel 4132C. The transmission chain 4132A is connected to the side of the movable sub-pedal 412 facing the fixed sub-pedal 411, and the extension direction is the same as the extension direction of the movable sub-pedal 412. The second gear 4132B is connected to the output shaft of the second reduction motor 4131, and the second gear 4132B is meshed with the transmission chain 4132A. The guide wheel 4132C is connected to the side of the movable sub-pedal 412 facing the fixed sub-pedal 411, and the guide wheel 4132C is provided with a limiting groove (not shown), and the transmission chain 4132A is slidably arranged in the limiting groove. In the above arrangement, the second gear 4132B rotates under the drive of the second reduction motor 4131, so that the transmission chain 4132A can move along the extension direction of the movable sub-pedal 412, thereby realizing the translation movement of the movable sub-pedal 412. The guide wheel 4132C is used to guide and support the transmission chain 4132A. A limit groove is provided on the guide wheel 4132C, which can reduce the risk of the transmission chain 4132A deviating from the moving trajectory during movement, thereby improving the stability and safety of the operating platform 40 during translational movement.

[0046] In one embodiment, one end of the transmission chain 4132A is fixed to the movable sub-pedal 412, and the other end is maintained at an appropriate tension by a tensioning assembly (not shown).

[0047] In one embodiment, the second transmission assembly 4132 may also include a transmission method such as a gear rack assembly, a ball screw, and a belt assembly, which is not limited here.

[0048] Please refer again Figure 4 In one embodiment, a second slider (not shown) is installed on one of the fixed sub-pedal 411 and the movable sub-pedal 412 , and a second guide rail 415 is installed on the other one, and the second slider is slidably disposed on the second guide rail 415 .

[0049] Specifically, when the second slider is mounted on the fixed sub-pedal 411, the second guide rail 415 is mounted on the movable sub-pedal 412. Conversely, when the second slider is mounted on the movable sub-pedal 412, the second guide rail 415 is mounted on the fixed sub-pedal 411. The second slider and the second guide rail 415 cooperate to reduce the risk of the movable sub-pedal 412 deviating from the moving track during the movement relative to the fixed sub-pedal 411, thereby improving the stability of the movable sub-pedal 412 during the movement.

[0050] In one embodiment, the second guide rail 415 includes any one of a V-shaped guide rail, a square rail, and a cylindrical guide rail, which is not limited herein.

[0051] In one embodiment, rolling elements such as balls (not shown) or rollers (not shown) may be provided inside the second slider. The balls or rollers are in contact with the second guide rail 415, which can reduce the friction between the second guide rail 415 and the second slider, thereby improving the operating efficiency of the lifting shield 20.

[0052] In one embodiment, the number of the second guide rails 415 and the second slider can include multiple, and the multiple second guide rails 415 are respectively arranged on different sides of the fixed sub-pedal 411 or the movable sub-pedal 412, and the second sliders are arranged one by one with the second guide rails 415, so as to further improve the stability of the movable sub-pedal 412 relative to the fixed sub-pedal 411 during the translation process.

[0053] Please continue reading Figure 4 In one embodiment, the translation mechanism 413 also includes a second tank chain wiring groove 4133, which is used to accommodate multiple cables and hoses during the translation movement. By placing the multiple cables and hoses in the second tank chain wiring groove 4133 in an orderly manner, the working area near the translation mechanism 413 can be made tidy and convenient for maintenance and troubleshooting.

[0054] In one embodiment, the automatic lifting operation platform 100 further includes a ladder 80 and a stabilizing member 90. The ladder 80 extends in the same direction as the pillar 10, and the stabilizing member 90 connects the top of the pillar 10 with the top of the ladder 80. Through the above configuration, the ladder 80 can be provided to facilitate operators to safely go up and down the operating platform 40, and the stabilizing member 90 can improve the stability of the ladder 80 connected to the pillar 10, and reduce the risk of the ladder 80 tilting.

[0055] In one embodiment, the step surface of the escalator 80 may be treated to prevent slipping, such as adding texture, laying anti-slip mats (not shown) or applying anti-slip coating (not shown) to prevent the operator from slipping during the climbing process.

[0056] In one embodiment, a plurality of supporting ribs (not shown) are connected to the periphery of the escalator 80 so that if an operator falls from the escalator 80 while climbing the escalator 80 , the operator can grab the supporting ribs to ensure the operator's safety.

[0057] In one embodiment, the stabilizing member 90 includes any one of a steel pipe and a chain, which is not limited herein.

[0058] Please refer again Figure 1 and Figure 2 In one embodiment, the safety protection process of the automatic lifting operation platform 100 includes:

[0059] The operator enters the operating platform 40 and can control the lifting mechanism 30 and the translation mechanism 413 through the control panel on the operating box 414 to achieve lifting and translation movements. It is understandable that there will be clear operating instructions and emergency stop buttons on the control panel to ensure that the operator can quickly and accurately perform necessary controls.

[0060] Under normal circumstances, when the operator wants to return to the ground, he controls the operation of the lifting mechanism 30 through the control panel on the operating box 414. The operating platform 40 will slowly descend back to the ground driven by the first reduction motor 31 on the pillar 10 and the multi-section hydraulic cylinder 50 to achieve smooth lifting movement.

[0061] When the device is powered off or mechanically fatigued, the first reduction motor 31 will lose its lifting function. At this time, the first reduction motor 31 with a deceleration function will be controlled by the safety program to start emergency deceleration braking, and start the first layer of protection of the automatic lifting operation platform 100 to prevent the operating platform 40 from falling rapidly in an instant.

[0062] The multi-section hydraulic cylinder 50 located inside the support 10 will play a second layer of protection. The multi-section hydraulic cylinder 50 can lock the position of the operating platform 40 when the power of the first reduction motor 31 is lost, so that the operating platform 40 can be stopped steadily after the deceleration movement is completed, thereby preventing the operating platform 40 from falling suddenly. At this time, a manual release valve is also provided in the hydraulic system to facilitate the operation of ground rescue personnel or the self-rescue of the operator trapped on the operating platform 40.

[0063] When the first reduction motor 31 and the multi-section hydraulic cylinder 50 are both inoperative, the ladder 80 will serve as the third layer of protection. The operator can climb down to the ground from the ladder 80 on the side of the support 10, which maximizes the safety of the operator and provides a variety of ways for the operator to safely leave the high altitude.

[0064] The above are only implementation methods of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
