[0032] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or there can be one or more centered elements therebetween. When an element is described as "connected to" another element, it can be directly connected to the other element, or there can be one or more centered elements therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are for illustrative purposes only.

[0033] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this utility model belongs. The terms used in this specification and in the description of this utility model are only for the purpose of describing specific embodiments and are not intended to limit the utility model. The term "and / or" used in this specification includes any and all combinations of one or more of the relevant listed items.

[0034] See also Figure 1 The lifting mechanism 1000 includes an installation assembly 1, a first lifting assembly 2, and a second lifting assembly 3, wherein the first lifting assembly 2 and the second lifting assembly 3 are both rotatably connected to the installation assembly 1. The first lifting assembly 2 and the second lifting assembly 3 are spaced apart along a first direction, and the first lifting assembly 2 and the second lifting assembly 3 are both used to connect to the equipment to be lifted, so that the first lifting assembly 2 and the second lifting assembly 3 jointly drive the equipment to be lifted to rise or fall along a second direction. The rotation axes of the first lifting assembly 2 and the second lifting assembly 3 are both parallel to a third direction, and the first direction, the second direction, and the third direction are perpendicular to each other. Initially, the equipment to be lifted is in a horizontal state, that is, the equipment to be lifted is parallel to the first direction and the second direction, and the first lifting assembly 2 and the second lifting assembly 3 are in a vertical state, that is, the first lifting assembly 2 and the second lifting assembly 3 are both arranged along the third direction. The first lifting assembly 2 and the second lifting assembly 3 drive the equipment to be lifted to rise or fall by the same distance, so that the equipment to be lifted can be stably lifted or fallen in a horizontal state. When the distances driven by the first lifting assembly 2 and the second lifting assembly 3 to move the device to be lifted are different, the first lifting assembly 2 and the second lifting assembly 3 rotate to adjust the device to be lifted to a tilted state with one end higher than the other. The first lifting assembly 2 and the second lifting assembly 3 can continue to drive the device to be lifted to move, and the first lifting assembly 2 and the second lifting assembly 3 continue to rotate, and the tilt angle of the device to be lifted changes accordingly, so that the lifting movement of the device to be lifted will not get stuck. In addition, by adjusting the distances driven by the first lifting assembly 2 and the second lifting assembly 3 to move the device to be lifted, the device to be lifted can be readjusted to a horizontal state, thereby allowing the device to be lifted and lowered smoothly.

[0035] For installation component 1 above, see Figure 1, the installation component 1 is used to fix the connection of the equipment to be installed. The installation component 1 includes a first installation component 11 and a second installation component 12, and the first installation component 11 and the second installation component 12 are arranged relative to each other along the first direction. The first installation component 11 is used to install the first lifting component 2, and the second installation component 12 is used to install the second lifting component 3. The first installation component 11 includes a first base plate 111, a first side plate 112 and a first limiter 113. There are two first side plates 112, and the first side plates 112 are arranged on the first base plate 111.

The first side plate 112 is provided with a first rotating hole 1121, and the two first rotating holes 1121 are arranged relative to each other along the third direction. The first rotating hole 1121 is used to be rotatably connected to the first lifting component 2. Along the second direction, the first limiter 113 and the first side plate 112 are arranged on the same side of the first base plate 111. In a direction parallel to the first direction and away from the second mounting member 12, the first rotation hole 1121 and the first stopper 113 are sequentially spaced apart, such that the first stopper 113 limits the maximum angle by which the end of the first lifting assembly 2, which is connected to the device to be lifted, can deflect away from the second lifting assembly 3. In the second direction, the first rotation hole 1121 and the first base plate 111 are spaced apart, such that the first base plate 111 limits the maximum angle by which the end of the first lifting assembly 2, which is connected to the device to be lifted, can deflect away from the second lifting assembly 3. Optionally, the first stopper 113 may be omitted, with the first base plate 111 alone limiting the position of the first lifting assembly 2. Optionally, this embodiment does not limit the connection method between the first bottom plate 111, the first side plate 112 and the first limiting member 113. The first side plate 112 and / or the first limiting member 113 can be detachably connected to the first bottom plate 111, or at least two of the first side plate 112, the first bottom plate 111 and the first limiting member 113 can be integrally formed.

[0036] The second mounting member 12 includes a second base plate 121, a second side plate 122, and a second limiting member 123. Two second side plates 122 are provided, and the second side plates 122 are arranged on the second base plate 121. The two second side plates 122 are arranged relative to each other along the third direction. The second side plates 122 are provided with second rotation holes 1221. The two second rotation holes 1221 are arranged relative to each other along the third direction. The second rotation holes 1221 are used for rotational connection with the second lifting assembly 3. Along the second direction, the second limiting member 123 and the second side plate 122 are arranged on the same side of the second base plate 121. Along a direction parallel to the first direction and away from the first mounting member 11, the second rotation hole 1221 and the second limiting member 123 are arranged in sequence at intervals, so that the second limiting member 123 limits the maximum angle of deflection of the end of the second lifting assembly 3 used for connecting the equipment to be lifted in the direction away from the first lifting assembly 2. Along the second direction, the second rotation hole 1221 and the second base plate 121 are spaced apart so that the second base plate 121 limits the maximum angle at which the end of the second lifting assembly 3 connected to the device to be lifted can deflect away from the first lifting assembly 2. Optionally, the second limiting member 123 may not be provided, and the second lifting assembly 3 may be limited only by the second base plate 121. Optionally, this embodiment does not limit the connection method between the second base plate 121, the second side plate 122, and the second limiting member 123. The second side plate 122 and / or the second limiting member 123 may be detachably connected to the second base plate 121, or at least two of the second side plate 122, the second base plate 121, and the second limiting member 123 may be integrally formed.

[0037] For the first lifting assembly 2, see Figure 1, the first lifting component 2 is rotatably connected to the first mounting member 11 and is arranged between the two first side panels 112. The first lifting component 2 includes a first lifting member 21, a first mounting seat 22 and a first rotating part 23. The first lifting member 21 is used to drive the equipment to be lifted to rise or fall along the second direction. One end of the first lifting member 21 is used to be connected to the equipment to be lifted, and the other end of the first lifting member 21 is fixedly connected to the first mounting seat 22. There are two first rotating parts 23, and the two first rotating parts 23 are arranged on both sides of the first mounting seat 22 along the third direction. A first rotating part 23 is inserted into a first rotating hole 1121, and the first rotating part 23 can rotate in the first rotating hole 1121. It can be understood that the first rotating part 23 can be set to a circular axis type, or it can be set to a hemispherical type, etc., as long as the first rotating part 23 can be rotatably set in the first rotating hole 1121. The first lifting assembly 2 also includes a first screw connection (not shown). The first mounting seat 22 is provided with a first screw hole 221, and the first rotating portion 23 is provided with a first connecting hole 231. The first screw connection passes through the first connecting hole 231 and is screwed into the first screw hole 221, thereby fixedly connecting the first rotating portion 23 to the first mounting seat 22. Along the third direction, the central axes of the two first rotating portions 23 coincide, and the central axes of the two first rotating portions 23 are both parallel to the third direction. With this arrangement, if one of the first lifting member 21, the first mounting seat 22, or the first rotating portion 23 is damaged, the corresponding component can be repaired or replaced without repairing or replacing the entire first lifting assembly 2. Alternatively, the first mounting seat 22 may be omitted, and the first rotating portion 23 may be provided on the first lifting body 211, so that the first lifting assembly 2 can be rotatably connected to the first mounting member 11. This reduces the number of components, lowers costs, simplifies the assembly steps, and makes assembly and disassembly of the first lifting assembly 2 more convenient.

[0038] In some embodiments, the arrangement of the two first rotating parts 23 is not limited to the above-described method. The first rotating parts 23 can also be arranged on the first mounting seat 22 by means of snap connection, welding, interference fit, or integral molding. Alternatively, the two first rotating parts 23 can also form a whole. The first mounting seat 22 is provided with a first rotating shaft (not shown in the figure). The first rotating shaft passes through the first mounting seat 22, and both ends of the first rotating shaft extend out of the first mounting seat 22. The two ends of the first rotating shaft extending out of the first mounting seat 22 respectively form two first rotating parts 23.

[0039] Regarding the above-mentioned first lifting member 21, the first lifting member 21 includes a first lifting body 211, a first lifting rod 212 and a first driving member 213. The first lifting rod 212 is movably arranged on the first lifting body 211. The first lifting rod 212 can extend from one end of the first lifting body 211, and by adjusting the extension length of the first lifting rod 212, the lifting distance of the equipment to be lifted can be adjusted. The other end of the first lifting body 211 is fixedly connected to the first mounting seat 22. It is understandable that the driving mode of the first lifting rod 212 can be pneumatic drive, hydraulic drive or electric drive. The first driving member 213 is arranged on the first lifting rod 212 for extending from one end of the first lifting body 211, and the first driving member 213 is used to be fixedly connected to the equipment to be lifted. It is understandable that multiple first lifting rods 212 can be provided, and the multiple first lifting rods 212 are all connected to the first driving member 213.

[0040] For the second lifting assembly 3, see Figure 1 , the second lifting assembly 3 is rotatably connected to the second mounting member 12 and is arranged between the two second side plates 122. The second lifting assembly 3 includes a second lifting member 31, a second mounting seat 32 and a second rotating part 33. The second lifting member 31 is used to drive the equipment to be lifted to rise or fall along the second direction. One end of the second lifting member 31 is used to be connected to the equipment to be lifted, and the other end of the second lifting member 31 is fixedly connected to the second mounting seat 32. There are two second rotating parts 33, and the two second rotating parts 33 are arranged on both sides of the second mounting seat 32 along the third direction. A second rotating part 33 is inserted into a second rotating hole 1221, and the second rotating part 33 can rotate in the second rotating hole 1221. It can be understood that the second rotating part 33 can be set to a circular axis type, or it can be set to a hemispherical type, etc., so long as the second rotating part 33 can be rotatably arranged in the second rotating hole 1221. The second lifting assembly 3 also includes a second screw connection (not shown). The second mounting base 32 is provided with a second screw hole 321, and the second rotating portion 33 is provided with a second connecting hole 331. The second screw connection passes through the second connecting hole 331 and is screwed into the second screw hole 321, thereby fixedly connecting the second rotating portion 33 to the second mounting base 32. Along the third direction, the central axes of the two second rotating portions 33 coincide, and the central axes of the two second rotating portions 33 are both parallel to the third direction. With this arrangement, if one of the second lifting member 31, the second mounting base 32, or the second rotating portion 33 is damaged, the corresponding component can be repaired or replaced without repairing or replacing the entire second lifting assembly 3. Alternatively, the second mounting base 32 may be omitted, and the second rotating portion 33 may be provided on the second lifting body 311, so that the second lifting assembly 3 can be rotatably connected to the second mounting member 12. This reduces the number of components, lowers costs, simplifies the assembly steps, and makes assembly and disassembly of the second lifting assembly 3 more convenient.

[0041] In some embodiments, the arrangement of the two second rotating parts 33 is not limited to the above-described method. The second rotating parts 33 can also be arranged on the second mounting seat 32 by means of snap connection, welding, interference fit, or integral molding. Alternatively, the two second rotating parts 33 can also form a whole. The second mounting seat 32 is provided with a second rotating shaft (not shown in the figure). The second rotating shaft passes through the second mounting seat 32, and both ends of the second rotating shaft extend from the second mounting seat 32. The ends of the second rotating shaft extending from the second mounting seat 32 respectively form two second rotating parts 33.

[0042] Regarding the above-mentioned second lifting member 31, the second lifting member 31 includes a second lifting body 311, a second lifting rod 312 and a second driving member 313. The second lifting rod 312 is arranged on the second lifting body 311 in a liftable manner. The second lifting rod 312 can extend from one end of the second lifting body 311, and by adjusting the extension length of the second lifting rod 312, the lifting distance of the equipment to be lifted can be adjusted. The other end of the second lifting body 311 is fixedly connected to the second mounting seat 32. It is understandable that the driving mode of the second lifting rod 312 can be pneumatic drive, hydraulic drive or electric drive. The second driving member 313 is arranged on the second lifting rod 312 for extending from one end of the second lifting body 311, and the second driving member 313 is used to be fixedly connected to the equipment to be lifted. It is understandable that multiple second lifting rods 312 can be provided, and the multiple second lifting rods 312 are all connected to the second driving member 313.

[0043] In some embodiments, the first rotating portion 23 can move within the first rotating hole 1121 in a direction perpendicular to the third direction, and the second side plate 122 restricts the movement of the second rotating portion 33 on the inner wall of the second rotating hole 1221. Optionally, the cross-section of the first rotating hole 1121 is runway-shaped, with the first side plate 112 forming a runway on the inner wall of the first rotating hole 1121. The first rotating portion 23 can rotate within the first rotating hole 1121 and move along the runway within the first rotating hole 1121. This runway arrangement allows the first lifting assembly 2 to rotate by moving within the first rotating hole 1121 when the first lifting assembly 2 rotates to its extreme position, thereby allowing the tilt angle of the device to be lifted to be finely adjusted. This arrangement increases the rotation range of the first lifting assembly 2, thereby increasing the adjustment range of the first lifting assembly 2. Furthermore, the second rotating portion 33 is restricted from moving in a direction perpendicular to the third direction, preventing the device to be lifted from moving along the first direction with the first lifting assembly 2 and the second lifting assembly 3, thereby ensuring that the position of the device to be lifted does not shift in the first direction.

[0044] In an embodiment of the present invention, the lifting mechanism 1000 includes a mounting assembly 1, a first lifting assembly 2, and a second lifting assembly 3. The first lifting assembly 2 and the second lifting assembly 3 are spaced apart along a first direction. The first lifting assembly 2 and the second lifting assembly 3 are both arranged on the mounting assembly 1, and the first lifting assembly 2 and the second lifting assembly 3 are used to connect the equipment to be lifted, and the first lifting assembly 2 and the second lifting assembly 3 are used to drive the equipment to be lifted to rise or fall along a second direction. The first lifting assembly 2 and the second lifting assembly 3 drive the equipment to be lifted to move the same distance so that the equipment to be lifted can rise or fall stably. The first lifting assembly 2 and the second lifting assembly 3 are both rotatably arranged on the mounting assembly 1, and the rotation axes of the first lifting assembly 2 and the second lifting assembly 3 are both parallel to the third direction, and the first direction, the second direction, and the third direction are perpendicular to each other. When the distances driven by the first lifting assembly 2 and the second lifting assembly 3 to move the equipment to be lifted are different, the rotation of the first lifting assembly 2 and the second lifting assembly 3 allows the equipment to be lifted to be adjusted to an inclined state with one end higher and the other end lower. The first lifting assembly 2 and the second lifting assembly 3 can continue to drive the equipment to be lifted to move, and the first lifting assembly 2 and the second lifting assembly 3 continue to rotate, and the inclination angle of the equipment to be lifted changes accordingly, and the upward or downward movement of the equipment to be lifted will not be stuck.

It is understood that multiple drive devices 5 can also be provided, with one drive device 5 used to drive one conveyor belt 42.
