[0045] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0046] Currently, two pneumatic cylinders are used to lift photovoltaic substrates. However, the two cylinders cannot guarantee that they transmit the same force to the structure to be lifted. This can cause the two ends of the lifting mechanism to be subjected to different forces, resulting in tilting, which in turn can cause the entire mechanism to become stuck or even cause the cylinder or other parts to malfunction. Therefore, the present application provides a single pneumatic cylinder. By using a single cylinder to drive the lifting mechanism, the lifting structure will not tilt due to uneven force, thereby reducing the failure rate of the lifting structure.

[0047] like Figures 1 to 3 As shown, the present application provides a single-cylinder lifting mechanism 1, comprising:

[0048] The cylinder 11 has a piston rod 111. When driven by the cylinder 11, the piston rod 111 moves in a first direction or a direction opposite to the first direction.

[0049] A first linkage assembly 12, the first linkage assembly 12 is connected to the piston rod 111, so as to rotate in a counterclockwise direction or a clockwise direction under the action of the piston rod 111;

[0050] Two second linkage components 13, the two second linkage components 13 are respectively rotatably connected to the first linkage component 12, so as to rise or fall in the vertical direction under the drive of the first linkage component 12;

[0051] The two lifting assemblies 14 are respectively connected to the two second linkage assemblies 13 . The lifting assemblies 14 are extended in the vertical direction to be lifted and lowered under the drive of the second linkage assemblies 13 .

[0052] The single-cylinder lifting mechanism 11 provided in the present application includes a cylinder 11, a first linkage assembly 12, two second linkage assemblies 13 and two lifting assemblies 14. The cylinder 11 has a piston rod 111, which is connected to the first linkage assembly. The piston rod 111 can be extended and retracted in the cylinder 11. Under the drive of the cylinder 11, the retractable rod can move in a first direction or in a direction opposite to the first direction. The piston rod 111 of the cylinder 11 is connected to the first linkage assembly 12. When the piston rod 111 moves in a first direction or a direction opposite to the first direction, it can drive the first linkage assembly 12 to rotate in a clockwise or counterclockwise direction. The two sides of the first linkage assembly 12 are also respectively connected to the second linkage assembly 13, so that the counterclockwise or clockwise rotation of one first linkage assembly 12 can simultaneously drive two second linkage assemblies 13 to rise or fall in the vertical direction, and each second linkage assembly 13 is connected to a lifting assembly 14, so that each second linkage assembly 13 can drive a lifting assembly 14 to rise or fall in the vertical direction when lifting.

[0053] Thus, the single-cylinder lifting mechanism 1 provided by the present application, through the arrangement of a first linkage assembly 12 and two second linkage assemblies 13, can simultaneously lift and lower two lifting assemblies 14 by a single cylinder 11. Since they are driven by the same cylinder 11, the two lifting assemblies 14 are subjected to the same force during the lifting process, and the problem of tilting of the lifting assemblies 14 due to different forces in the related art will not occur. This avoids the occurrence of jamming of the mechanism and damage to parts in the mechanism. Therefore, the single-cylinder lifting mechanism 1 provided by the present application can reduce the failure rate of the mechanism.

[0054] like Figures 1 to 3 As shown, in the embodiment of the present application, it also includes:

[0055] A first rotating shaft 15, the first rotating shaft 15 is rotatably connected to the first linkage assembly 12, and two ends of the first rotating shaft 15 are fixedly connected to two second linkage assemblies 13;

[0056] The fixing member 16 is connected to the first rotating shaft 15 so that the position of the first rotating shaft 15 remains unchanged.

[0057] In this embodiment, the single-cylinder lifting mechanism 1 includes a cylinder 11, a first linkage assembly 12, two second linkage assemblies 13, two lifting assemblies 14, a first rotating shaft 15 and a fixing member 16. The piston rod 111 of the cylinder 11 is connected to the first linkage assembly 12. When the piston rod 111 moves in a first direction or a direction opposite to the first direction, it can drive the first linkage assembly 12 to rotate in a counterclockwise direction or a clockwise direction. The first linkage assembly 12 is also rotationally connected to the first rotating shaft 15. The first rotating shaft 15 is positioned by the first fixing member 16 while being rotationally connected to the first linkage assembly 12, so that the position of the first rotating shaft 15 remains unchanged. Therefore, when the first linkage assembly 12 rotates, the first rotating shaft 15, which remains in the same position, can be driven to rotate. Two second linkage components 13 are fixedly connected to both ends of the first rotating shaft 15. When the first rotating shaft 15 rotates, the two second linkage components 13 can both rotate. After the second linkage components 13 rotate, the second linkage components 13 can be raised or lowered in the vertical direction, thereby driving the two lifting components 14 to rise and fall.

[0058] like Figures 1 to 3 As shown, in the embodiment of the present application, the first linkage component 12 includes:

[0059] A fisheye bearing 121 , wherein a first end of the fisheye bearing 121 is connected to the piston rod 111 of the cylinder 11 ;

[0060] A second rotating shaft 122 , on which the second end of the fisheye bearing 121 is sleeved;

[0061] The first connecting plate 123 has a first end rotatably connected to the second rotating shaft 122 , and a second end rotatably connected to the first rotating shaft 15 .

[0062] In this embodiment, the fisheye bearing includes an outer ring / inner ring / ball and a retaining frame. Its principle is to minimize the contact area between the outer ring / inner ring and the ball, thereby reducing friction and wear. The ball of the fisheye bearing is pressed into two "V"-shaped grooves, which can reduce the lateral (radial) movement of the ball, thereby increasing its load-bearing capacity. The fisheye bearing fixes the ball through a retaining frame, which can be made of metal or plastic, depending on the purpose of the fisheye bearing. In the gap of the retaining frame, the ball will be able to move freely and evenly distribute the load on the entire contact surface, which helps to reduce friction and wear and can withstand higher loads. The fisheye bearing can be a structure that has been disclosed in the relevant technology, so it will not be described in detail here.

[0063] In this embodiment, the first linkage assembly 12 includes a fisheye bearing 121, a second rotating shaft 122, and two first connecting plates 123. The fisheye bearing 121 has a first end and a second end. The first end of the fisheye bearing 121 is screwed onto the piston rod 111 of the cylinder 11 to connect with the piston rod 111, so that the fisheye bearing 121 can move in the first direction or the second direction under the drive of the piston rod 111. The second end of the fisheye bearing 121 is sleeved outside the second rotating shaft 122, and the second rotating shaft 122 is fixed to the fisheye bearing 121 by a retaining spring to prevent it from falling out. The two ends of the second rotating shaft 122 along the length direction are rotatably connected to the first rotating shaft 15 by two first connecting plates 123. The fixing member 16 is a bearing with a seat, so that the fixing member 16 can be rotatably connected to the first rotating shaft 15. The other end of the fixing member 16 is fixed to the working plate 17 by a bolt, so that the position of the first rotating shaft 15 is restricted by the fixing member 16, so that the first rotating shaft 15 can rotate without changing its position. When the fisheye bearing 121 moves in the first direction or in a direction opposite to the first direction, it can drive the second rotating shaft 122 to rotate counterclockwise or clockwise. The first rotating shaft 15 and the second rotating shaft 122 are rotatably connected via two first connecting plates 123, and the position of the first rotating shaft 15 remains unchanged. Therefore, when the second rotating shaft 122 rotates, it can drive the first rotating shaft 15 to rotate in the same direction as the second rotating shaft 122, thereby achieving rotation of the first rotating shaft 15.

[0064] like Figures 1 to 3 As shown, in the embodiment of the present application, the second linkage component 13 includes:

[0065] A second connecting plate 131, a first end of the second connecting plate 131 is fixedly connected to the first rotating shaft 15;

[0066] The third connecting plate 132 has a first end rotatably connected to the second connecting plate 131 , and a second end connected to the first end of the lifting assembly 14 .

[0067] In this embodiment, the second linkage assembly 13 includes a second connecting plate 131 and a third connecting plate 132. The third connecting plate 132 is arranged relative to the second connecting plate 131 away from the first rotating shaft 15. The first end of the second connecting plate 131 is fixedly connected to one end of the first rotating shaft 15. The second end of the second connecting plate 131 is rotatably connected to the first end of the third connecting plate 132 through a rotating bearing and a pin. The second end of the third connecting plate 132 is connected to the first end of the lifting assembly 14. Therefore, when the first rotating shaft 15 rotates, the second connecting plate 131 fixedly connected to the first rotating shaft 15 can be driven to rotate. When the second connecting plate 131 rotates, it can drive the first end of the third connecting plate 132 rotatably connected to it to rotate, and the second end of the third connecting plate 132 is connected to the lifting assembly 14. The lifting assembly 14 extends in the vertical direction and can only move in the vertical direction. Therefore, the second end of the third connecting plate 132 is lifted and lowered in the vertical direction under the joint action of the second connecting plate 131 and the lifting assembly 14, and the lifting of the third connecting plate 132 will drive the lifting of the lifting assembly 14.

[0068] like Figures 1 to 3 As shown, in the embodiment of the present application, it also includes:

[0069] A working plate 17 is provided above the first linkage assembly 12 and the second linkage assembly 13 and is spaced apart from the first linkage assembly 12 and the second linkage assembly 13;

[0070] The first rotating shaft 15 is connected to the working plate 17 through a fixing member 16 so that the position of the first rotating shaft 15 remains unchanged; the lifting assembly 14 passes through the working plate 17 so that the lifting assembly 14 can move vertically relative to the working plate 17 under the restriction of the working plate 17.

[0071] In this embodiment, the single-cylinder lifting mechanism 1 includes a cylinder 11, a first linkage assembly 12, two second linkage assemblies 13, two lifting assemblies 14, a first rotating shaft 15, a fixing member 16 and a working plate 17. The cylinder 11 has a piston rod 111, which can perform telescopic movement in the cylinder 11 and move in a first direction or a direction opposite to the first direction, thereby driving the fisheye bearing 121 of the first linkage assembly 12 to move in the first direction or a direction opposite to the first direction, and the fisheye bearing 121 is sleeved on the second rotating shaft 122, so that the second rotating shaft 122 can rotate counterclockwise or clockwise. The two ends of the second rotating shaft 122 are also rotatably connected to the first rotating shaft 15 by two first connecting plates 123 respectively, and the first rotating shaft 15 is restricted by the fixing member 16 and the working plate 17, that is, it can rotate on its own, but its position remains unchanged. , so that the first rotating shaft 15 can rotate counterclockwise or clockwise under the joint action of the first connecting plate 123 and the working plate 17, but the position remains unchanged. The two ends of the first rotating shaft 15 are fixedly connected to the two second connecting plates 131. The second connecting plate 131 rotates under the action of the first rotating shaft 15, and the third rotating plate is rotatably connected to the second rotating plate, and the third rotating plate is movably connected to the working plate 17 in the vertical direction through the lifting assembly 14, so that the working plate 17 limits the movement direction of the lifting assembly 14 and the second end of the third rotating plate, and can only move in the vertical direction, and then the third connecting plate 132 can move in the vertical direction under the action of the second connecting plate 131, the lifting assembly 14 and the working plate 17, and the movement of the third connecting plate 132 can drive the lifting assembly 14 to move up and down in the vertical direction.

[0072] like Figures 1 to 3 As shown, in the embodiment of the present application, the lifting assembly 14 includes:

[0073] A lifting rod 141, wherein a first end of the lifting rod 141 is connected to the second end of the third connecting plate 132, the first end of the lifting rod 141 is located on a first side of the working plate 17, and a second end of the lifting rod 141 passes through the working plate 17 and is located on a second side of the working plate 17, and the second end of the lifting rod 141 is a free end;

[0074] The linear bearing 142 , the lifting rod 141 is movably connected to the working plate 17 along the vertical direction through the linear bearing 142 .

[0075] In this embodiment, the lifting assembly 14 includes a lifting rod 141 and a linear bearing 142. The lifting rod 141 has a first end and a second end. The first end is located on a first side of the working plate 17, and the second end is located on a second side of the working plate 17. The first side of the working plate 17 is also provided with a first linkage assembly 12, a second linkage assembly 13, and a cylinder 11, while the second side of the working plate 17 is used to accommodate a structure to be lifted, such as a photovoltaic substrate. The first end of the lifting rod 141 is connected to the second end of the third connecting plate 132. The lifting rod 141 is connected to the working plate 17 via the linear bearing 142, which is bolted to the working plate 17. This allows the lifting rod 141 to move vertically relative to the working plate 17, thereby restricting the movement direction of the second end of the third connecting plate 132 to which the lifting rod 141 is connected, allowing the second end of the third connecting plate 132 and the lifting assembly 14 to move vertically.

[0076] like Figures 1 to 3 As shown, in the embodiment of the present application, it also includes:

[0077] The bottom plate 18 is provided with a cylinder 11 , and the cylinder 11 is rotatably connected to the bottom plate 18 .

[0079] In this embodiment, when the cylinder 11 and the base plate 18 are connected through a bearing, a retaining spring is also provided at the connection point, thereby limiting the bearing through the retaining spring to prevent the bearing from running out due to excessive rotation time.

[0080] like Figures 1 to 3 As shown, in the embodiment of the present application, the fixing member 16 is a bearing with a seat, a bearing end of the bearing with a seat is rotatably connected to the first rotating shaft 15, and the other end of the bearing with a seat is fixedly connected to the working plate 17.

[0086] Thus, the single-cylinder lifting mechanism 1 provided by the present application can drive two lifting assemblies 14 to lift and lower simultaneously through the arrangement of a first linkage assembly 12 and two second linkage assemblies 13 by a single cylinder 11. Since the two lifting assemblies 14 are driven by the same cylinder 11, they are subjected to the same force during the lifting process. Therefore, the mechanism can be widely used in non-standard equipment. There is no need to consider the problem of asynchronous air intake of the two cylinders 11 caused by the different lengths of the air pipes, the load of the mechanism not being at the center point, and the unbalanced thrust generated by the cylinder 11. The problem of tilting of the lifting assembly 14 due to different forces in the related art will not occur. The mechanism is prevented from getting stuck and the damage of parts in the mechanism is also avoided. The synchronous lifting effect that originally required two cylinders 11 to achieve is now achieved by one cylinder 11, which greatly improves the stability of the entire mechanism and reduces the failure rate. The mechanism is relatively simple in structure, low in cost, and easy to operate. It utilizes one cylinder 11 to achieve the effect of synchronous lifting of two cylinders 11, and has low subsequent maintenance costs.
