Description

Technical Field

[0001] This utility model relates to the field of operating platform technology, specifically to a flipping platform. Background Technology

[0002] Due to the high altitude of aircraft, a work platform is needed to support workers during manufacturing or maintenance. To save space, existing methods use a flip-up platform design. The platform rotates to its working position when needed and retracts when not in use, saving space. However, existing flip-up platforms rely solely on a flipping arm for rotation support and lack a locking mechanism. Under load, the platform is prone to continuing to rotate or sway. When maintenance or production personnel stand on the flip-up platform, stability is poor, safety is low, and accidents are easily caused. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a flipping platform, which prevents the flipping component from falling off by setting an anti-fall-off structure between the drive device and the flipping component, so that the flipping component can maintain a stable working state, thereby ensuring the stability and safety of the flipping platform during use.

[0004] This utility model provides a flipping platform to solve the above-mentioned technical problems, comprising:

[0005] Base

[0006] A flipping component is rotatably connected to the base, and an extension component is movably provided on the flipping component. A telescopic mechanism drives the extension component to extend or retract from the flipping component.

[0007] A driving device drives the flipping component to flip, and an anti-detachment structure is provided between the driving device and the flipping component.

[0008] Furthermore, the driving device includes a driving component, multiple sets of rotating arms, and a connecting component. The driving component includes a fixed part connected to the flipping assembly and a movable part connected to the connecting component. The movable part can move along the axial direction of the flipping assembly. One end of the rotating arm is hinged to the base, and the other end is hinged to the connecting component.

[0009] Furthermore, the fixed part is a drive motor, the output end of which is connected to one end of a lead screw rotatably mounted on the flipping assembly, and the movable part is a threaded sleeve that is threadedly engaged with the lead screw.

[0010] Furthermore, the flipping assembly is provided with several sets of axially extending first slide rails, and the connecting member is provided with a first slider that slides in cooperation with the first slide rails.

[0011] Furthermore, the anti-detachment structure includes a limiting rod extending along the axial direction of the flipping assembly on the flipping assembly and a solenoid valve on the connecting member. The limiting rod is provided with a plurality of limiting ports that cooperate with the limiting blocks on the solenoid valve in the axial direction.

[0012] Furthermore, the flipping assembly includes a flipping frame with an opening on one side, and the flipping frame has a cavity for accommodating the extension assembly. The extension assembly extends or retracts from the opening, and a first anti-slip plate is provided on the side of the flipping frame away from the driving device.

[0013] Furthermore, the extension component includes an extension frame, and a second anti-slip plate is provided on the side of the extension frame away from the driving device. The telescopic mechanism includes a telescopic cylinder provided on the flipping component, and the output end of the telescopic cylinder is connected to the extension frame.

[0014] Furthermore, the flipping assembly is provided with multiple sets of axially extending second slide rails, and the expansion frame is provided with a second slider that slides in cooperation with the second slide rails.

[0015] Furthermore, the flipping assembly is provided with a stop that can abut against the base.

[0016] Furthermore, the flipping assembly is also provided with a protective cover, and the bottom of the protective cover is provided with a clearance opening to allow the rotating arm to move.

[0017] The beneficial effects of this utility model are as follows: The base is used to install the tilting platform, fixing it in the required position. The tilting component is rotatably connected to the base and tilted by a drive device. When the tilting platform is needed, the drive device drives the tilting component to tilt and unfold from the base to the required angle, facilitating worker standing or placing objects. When not in use, the drive device drives the tilting component to tilt in the opposite direction, folding it back onto the base, saving space. The anti-fall-off structure restricts the tilting component's tilting when the drive device's limit switch fails, thus ensuring the stability of the tilting platform during use and increasing safety. The movable extension component on the tilting component expands the usable range of the platform. When a larger operating platform is needed, the extension component can be extended from the tilting component via a telescopic mechanism to increase the platform area. In summary, this utility model can both expand the working area of ​​the tilting platform as needed and restrict the tilting component's tilting when the self-locking mechanism fails, preventing fall-off, improving support, and ensuring the stability and safety of the tilting platform during use.

Detailed Implementation

[0024] Referring to the accompanying drawings, the specific embodiments of this utility model will be described in detail.

[0025] Reference Figures 1 to 4 This utility model provides a flipping platform, including a base 100, a flipping component 200, and a driving device 500. The base 100 is used to install the flipping platform and fix it in the desired position. The driving device 500 is located at the bottom of the flipping component 200, and the flipping component 200 can rotate relative to the base 100 through the driving device 500, so that it can be unfolded or retracted from the base 100.

[0026] The flipping assembly 200 is rotatably connected to the base 100. Further, the flipping assembly 200 includes a flipping frame 220 with an opening on one side, the upper end of which is hinged to the base 100 via a shaft. The flipping frame 220 adopts a frame structure, which reduces weight and provides installation space for the expansion assembly 300. Further, a first anti-slip plate 222 is provided on the side of the flipping frame 220 away from the drive device 500, i.e., the operating surface of the flipping frame 220 is provided with a first anti-slip plate 222 to prevent workers from slipping and improve safety. Further, the flipping assembly 200 is also provided with a protective cover 250, the bottom of which has a clearance opening to allow space for the rotating arm 520. The protective cover 250 protects the drive device 500.

[0027] An extension component 300 is movably mounted on the flipping component 200, and a telescopic mechanism 400 drives the extension component 300 to extend or retract from the flipping component 200. Further, the flipping frame 220 has a cavity 221 for accommodating the extension component 300. When the extension component 300 extends or retracts from the opening, it is hidden within the cavity 221 and stored there when not in use. The cavity 221 also restricts the movement of the extension component 300, causing it to move along the axial direction of the flipping component 200. This expands the usable range of the flipping platform; when a larger operating platform is needed, the extension component 300 can be extended from the flipping component 200 via the telescopic mechanism 400.

[0028] Furthermore, the extension component 300 includes an extension frame 310, and a second anti-slip plate 311 is provided on the side of the extension frame 310 away from the driving device 500. That is, the operating surface of the extension frame 310 is provided with a second anti-slip plate 311 to prevent slipping when used after extension, thereby improving safety. At the same time, the extension frame 310 also adopts a frame structure, which can reduce the weight.

[0029] Furthermore, the telescopic mechanism 400 includes a telescopic cylinder mounted on the flipping assembly 200. The output end of the telescopic cylinder is connected to the extension frame 310. The telescopic cylinder can be a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder. In this embodiment, an electric cylinder is used. The extension and retraction of the electric cylinder's telescopic rod drives the extension frame 310 to extend or retract from the flipping frame 220. Furthermore, the flipping assembly 200 is provided with multiple sets of axially extending second slide rails 230, and the extension frame 310 is provided with second sliders 312 that slide in cooperation with the second slide rails 230. Through the cooperation of the second slide rails 230 and the second sliders 312, the movement of the extension frame 310 can be guided, ensuring its stable operation.

[0030] The driving device 500 is used to drive the flipping assembly 200 to flip. When the flipping platform is needed, the driving device 500 drives the flipping assembly 200 to flip and unfold from the base 100 to the required angle, making it convenient for workers to stand or place objects. When it is not needed, the driving device 500 drives the flipping assembly 200 to flip in the opposite direction, so that it is folded up on the base 100, saving space. Furthermore, the flipping assembly 200 is provided with a stop 240 that can abut against the base 100. At this time, when the flipping assembly 200 is flipped to a perpendicular state to the base 100, the stop 240 can abut against the base 100, limiting its movement and supporting the flipping assembly 200.

[0031] Further, the driving device 500 includes a driving member 510, multiple sets of rotating arms 520, and a connecting member 530. The driving member 510 includes a fixed part connected to the flipping assembly 200 and a movable part connected to the connecting member 530. The movable part can move along the axial direction of the flipping assembly 200. One end of the rotating arm 520 is hinged to the base 100, and the other end is hinged to the connecting member 530. When the movable part of the driving member 510 moves along the axial direction of the flipping assembly 200, it drives the connecting member 530 to move along the axial direction of the flipping assembly 200. Due to the length limitation of the rotating arm 520, the rotating arm 520 pushes the flipping assembly 200 to flip around the base 100. The flipping angle of the flipping assembly 200 can be controlled according to the moving distance of the movable part. The driving member 510 can be a hydraulic motor, an electric motor, an electric cylinder, a hydraulic cylinder, etc., as long as it can make the movable part move along the axial direction of the flipping assembly 200.

[0032] In this embodiment, the fixed part is a drive motor 511, and the output end of the drive motor 511 is connected to one end of the lead screw 513 rotatably mounted on the flipping assembly 200. The movable part is a threaded sleeve 512, which is threadedly engaged with the lead screw 513. Since the movable part is the threaded sleeve 512 and is mounted on the connecting member 530, the threaded sleeve 512 can be prevented from rotating. When the drive motor 511 drives the lead screw 513 to rotate, the threaded sleeve 512 drives the connecting member 530 to move along the axial direction of the lead screw 513. Furthermore, the flipping assembly 200 is provided with several sets of axially extending first slide rails 210, and the connecting member 530 is provided with first sliders 531 that slidably engage with the first slide rails 210. In this case, the cooperation between the first slide rails 210 and the first sliders 531 can guide the sliding of the connecting member 530 and also prevent the connecting member 530 from rotating.

[0033] A non-detachment structure 600 is provided between the drive device 500 and the tilting assembly 200 to prevent the tilting assembly 200 from detaching, thereby ensuring the stability of the tilting platform during use. Preferably, two sets of non-detachment structures 600 are provided and arranged symmetrically along the axis of the tilting assembly 200. Further, the non-detachment structure 600 includes a limiting rod 610 extending axially from the tilting assembly 200 and a solenoid valve 620 on the connector 530. The limiting rod 610 has a plurality of limiting ports 611 arranged axially to cooperate with the limiting blocks 621 on the solenoid valve 620.

[0034] In this manner, when the flipping assembly 200 is unfolded or retracted, the solenoid valve 620 is energized and the limit block 621 is not extended. When the flipping assembly 200 is flipped to the required position for load use, the solenoid valve 620 is de-energized. At this time, the limit block 621 may be located between two adjacent limit ports 611. Due to the restriction of the limit rod 610, the limit block 621 is always in a retracted state; the limit block 621 may also be located at the limit port 611 position, extending into the limit port 611.

[0035] Under normal circumstances, the rotation angle of the flipping assembly 200 is limited by the limiter of the drive device 500 itself. When the limit block 621 is between the two limit ports 611 and the limit of the drive device 500 on the flipping assembly 200 fails, the flipping assembly 200 will continue to rotate. During the rotation of the flipping assembly 200, the limit rod 610 and the solenoid valve 620 move relative to each other. When the limit block 621 on the solenoid valve 620 moves to the position of the adjacent limit port 611, the limit block 621 extends into the limit port 611 to limit the rotation of the flipping assembly 200 and lock it. This prevents the flipping assembly 200 from falling due to wear between the lead screw 513 and the screw sleeve 512 or the failure of the self-locking of the drive device 500. It also prevents the flipping assembly 200 from rotating due to misoperation, which causes the lead screw 513 to rotate and the screw sleeve 512 to move, driving the connecting piece 530 to move. This greatly improves the stability and safety of the flipping platform during use.
