[0029] In the lifting device provided by the embodiment, the wiring structure 300 is used for arranging the connecting lines of the secondary lifting structure 200, wherein the wiring arm 310 is connected between the first end of the first drag chain 320 and the first supporting seat 220, so that the wiring arm 310 and the first end of the first drag chain 320 can synchronously move up and down with the first supporting seat 220; the first end of the second drag chain 330 is connected to the first supporting seat 220, and the second end of the second drag chain 330 is connected to the second supporting seat 240, so that the second end of the second drag chain 330 can synchronously move up and down with the second supporting seat 240 relative to the first supporting seat 220.

[0030] In the assembly, the connection lines involved in the secondary lifting structure 200 at least include the first connection line of the first lifting assembly 210, the second connection line of the electrical components located in the first holder 220 and the third connection line of the electrical components located in the second holder 240, wherein the first connection line extends away from the first lifting assembly 210 to the first end of the first drag chain 320 and is arranged to extend in the first drag chain 320, then extends out of the second end of the first drag chain 320 and is connected to the power supply; the second connection line extends away from the first holder 220 to the first end of the wiring arm 310 and is arranged along the extension direction of the wiring arm 310 to the wiring arm 310, then extends to the first end of the first drag chain 320 and is arranged to extend in the first drag chain 320, then extends out of the first drag chain 320 and is connected to the power supply; the third connection line extends away from the second holder 240 to the second end of the second drag chain 330 and is arranged to extend in the second drag chain 330, then extends out of the first end of the second drag chain 330 and extends to the first end of the wiring arm 310, then is arranged along the extension direction of the wiring arm 310 to the wiring arm 310 and extends to the first end of the first drag chain 320, then is arranged to extend in the first drag chain 320, then extends out of the first drag chain 320 and is connected to the power supply, so as to realize the wiring of the connection lines involved in the secondary lifting structure 200, and ensure the follow-up protection of the wiring structure 300 to the connection lines during the operation of the secondary lifting structure 200, thereby improving the arrangement neatness and stable connection of the connection lines, and ensuring the stable operation of the secondary lifting structure 200 and the lifting device, and reducing the occurrence of the connection lines being hung, pulled, short-circuited and stretched to be broken during the operation.

[0031] In the lifting device, the first drag chain 320 is arranged in the first accommodating area 10A, and the first holder 220 and the second holder 240 for supporting the materials are arranged in the second accommodating area 10B, so as to reduce the occupation of the first drag chain 320 to the side areas of the first holder 220 and the second holder 240, thereby reducing the limitation on the horizontal supporting size of the first holder 220 and the second holder 240, making the horizontal supporting size range of the first holder 220 and the second holder 240 larger, and being applicable to the support of materials with a larger size range, thereby improving the size application range of the lifting device for supporting materials.

[0032] In addition, the lifting device is provided with the secondary lifting structure 200 for supporting and lifting driving of the materials, and the lifting stroke is the sum of the lifting strokes of the first lifting assembly 210 and the second lifting assembly 230, thereby increasing the lifting stroke of the lifting device and reducing the requirement on the lifting stroke of the first lifting assembly 210 and the second lifting assembly 230, and correspondingly improving the stroke application range of the lifting device for supporting and lifting movement of the materials.

[0033] The secondary lifting structure 200 can increase the lifting stroke of the lifting device, reduce the requirement for the lifting stroke of the first lifting assembly 210 and the second lifting assembly 230, and correspondingly improve the stroke application range of the lifting device for supporting the lifting movement of the material. The wiring structure 300 can realize the wiring of the connecting lines involved in the secondary lifting structure 200, and can ensure the follow-up protection of the connecting lines by the wiring structure 300 during the operation of the secondary lifting structure 200, correspondingly improve the arrangement neatness and stable connection of the connecting lines, and further ensure the stable operation of the secondary lifting structure 200 and the lifting device, and reduce the occurrence of the hanging, pulling, short circuiting and stretching to breaking of the connecting lines during the operation. The first drag chain 320 and the first and second supporting seats 220 and 240 are arranged in different accommodation areas, which can reduce the occupation of the first drag chain 320 to the side areas of the first and second supporting seats 220 and 240, thereby reducing the limitation on the horizontal supporting size of the first and second supporting seats 220 and 240, making the horizontal supporting size range of the first and second supporting seats 220 and 240 larger, and being applicable to the supporting of materials with a larger size range, and further improving the size application range of the lifting device for supporting the material.

[0034] Specifically, the top of the second supporting seat 240 can be provided with a position sensor 400 for detecting the state of the material supported by the second supporting seat 240, and the connecting lines of the position sensor 400 can be arranged in the second drag chain 330, the wiring arm 310 and the first drag chain 320 in sequence.

[0035] In the embodiment, as shown in Figure 1 and Figure 2As shown, the middle region of the first holder 220 is provided with an embedding hole 221, and the second holder 240 is matched with the embedding hole 221. The second lifting assembly 230 is configured to drive the second holder 240 to descend into the embedding hole 221 or to rise to a target height out of the embedding hole 221. The first holder 220 and the second holder 240 are used to support the material, and the second holder 240 is located in the middle region of the first holder 220. When the second holder 240 is driven by the second lifting assembly 230 to descend into the embedding hole 221, the second holder 240 is located in the middle region of the first holder 220 and the top surface of the second holder 240 is coplanar with the top surface of the first holder 220. The top surfaces of the first holder 220 and the second holder 240 jointly form a larger supporting surface, and the material can be placed on the second holder 240. At this time, the material is located in the middle region of the first holder 220, thereby improving the stability of the first holder 220 and the second holder 240 in supporting the material. When the lifting stroke of the material is greater than the lifting driving stroke of the first lifting assembly 210 or the material is supported by the second holder 240 to move downward, the second holder 240 can be driven by the second lifting assembly 230 to support the material in the middle region and separate from the first holder 220, thereby ensuring the stability of the second holder 240 in supporting the material. When the second holder 240 supports the material to descend into the embedding hole 221, as described above, the material is located in the middle region of the first holder 220, thereby improving the stability of the secondary lifting structure 200 in supporting the material.

[0036] In this embodiment, as shown in Figure 1 and Figure 2 As shown, the top surface of the first holder 220 is provided with a first supporting plate 250 extending outward, and the length of the first supporting plate 250 extending out of the first holder 220 can be adjusted. The top surface of the second holder 240 is provided with a second supporting plate 260 extending outward, and the length of the second supporting plate 260 extending out of the second holder 240 can be adjusted. When the second holder 240 is embedded in the embedding hole 221, the top surface of the second supporting plate 260 is coplanar with the top surface of the first supporting plate 250. The top surface of the first supporting plate 250 simultaneously serves as the effective supporting top surface of the first holder 220. By adjusting the length of the first supporting plate 250 extending out of the first holder 220, the supporting area of the effective supporting top surface can be adjusted, so that the first holder 220 can adapt to the support of the material of a corresponding size. Similarly, the top surface of the second supporting plate 260 simultaneously serves as the effective supporting top surface of the second holder 240. By adjusting the length of the second supporting plate 260 extending out of the second holder 240, the supporting area of the effective supporting top surface can be adjusted, so that the second holder 240 can adapt to the support of the material of a corresponding size. Thus, the applicable range of the size of the material supported by the secondary lifting structure 200 and the stability of the material supported by the secondary lifting structure 200 are further increased, and the applicability and the running stability of the lifting device are correspondingly improved.

[0037] In the embodiment, the first support base 220 is provided with a plurality of first connecting areas 22A, and each first connecting area 22A is provided with a first connecting hole 222. Some or all of the first connecting areas 22A are used as first effective areas, and the first support plate 250 corresponds to each first effective area. The first support plate 250 is provided with a second connecting hole 251, and the first connecting hole 222 and the second connecting hole 251 are detachably connected by a first connecting piece. One of the first connecting hole 222 and the second connecting hole 251 is a waist-shaped hole extending along the length direction of the first support plate 250.

[0038] The plurality of first connecting areas 22A are distributed along the circumference of the first support base 220 and are arranged at the edge thereof. In use, some or all of the first connecting areas 22A can be determined as first effective areas according to the shape of the material, and the first support plate 250 is connected to the first effective areas. The first support plate 250 extends outwardly from the first support base 220, thereby increasing the supporting size of the corresponding area of the first support base 220, ensuring the stability of the support of the material, and improving the supporting application range of the first support base 220 to the size of the material.

[0039] Specifically, the first connecting piece is sequentially inserted into the second connecting hole 251 and the first connecting hole 222 and is locked. The direction of the first support plate 250 is adjusted so that the length direction of the waist-shaped hole is consistent with the length direction of the first support plate 250. At this time, the length direction of the waist-shaped hole is consistent with the direction in which the corresponding first connecting area 22A deviates from the central area of the first support base 220. The length of the first support plate 250 extending outwardly from the first support base 220 is adjusted along the length direction of the waist-shaped hole. Then, the relative positions of the first connecting hole 222 and the second connecting hole 251 are locked by the first connecting piece, thereby locking the first support plate 250 to the first support base 220. When it is necessary to adjust the length of the first support plate 250 extending outwardly from the first support base 220, the first connecting piece is unlocked, and the corresponding positions of the first connecting hole 222 and the second connecting hole 251 are adjusted along the length direction of the waist-shaped hole, thereby adjusting the length of the first support plate 250 extending outwardly from the first support base 220. After the adjustment is completed, the first connecting piece is locked again.

[0040] Specifically, the number of first connecting holes 222 in each first connecting area 22A can be multiple, and the plurality of first connecting holes 222 are arranged in a straight line along the direction in which the first connecting area 22A deviates from the central area of the first support base 220. Correspondingly, the number of second connecting holes 251 in the first support plate 250 is also multiple, and the plurality of second connecting holes 251 are arranged along the length direction of the second support plate 260. Furthermore, some or all of the plurality of second connecting holes 251 correspond to the plurality of first connecting holes 222 one by one, and the corresponding second connecting hole 251 and first connecting hole 222 are detachably connected by the first connecting piece, thereby improving the firmness and stability of the connection between the first support plate 250 and the first support base 220.

[0041] The first connecting member can be in the form of a bolt and a nut, or other detachable locking forms capable of locking and loosening the first connecting hole 222 and the second connecting hole 251.

[0042] The first support plate 250 is arranged in a similar manner to the first support base 220. In this embodiment, the second support base 240 is provided with a plurality of second connecting areas 24A, and each second connecting area 24A is provided with a third connecting hole 241. Some or all of the second connecting areas 24A are used as second effective areas, and the second support plate 260 corresponds to each second effective area. The second support plate 260 is provided with a fourth connecting hole 261, and the fourth connecting hole 261 is detachably connected to the third connecting hole 241 by a second connecting member. One of the third connecting hole 241 and the fourth connecting hole 261 is a waist-shaped hole extending along the length direction of the second support plate 260. The second support plate 260 is connected to the second support base 240 and the relative position is adjusted by the third connecting hole 241, the fourth connecting hole 261 and the second connecting member, so as to realize the installation of the second support plate 260 on different second connecting areas 24A of the second support base 240, and the adjustment of the length of the second support plate 260 extending out of the second support base 240, thereby improving the supporting application range of the second support base 240 to the size of the material.

[0043] In this embodiment, the top of the first support base 220 is provided with a supporting boss 223, and the top surface of the supporting boss 223 is coplanar with the top surface of the first support plate 250. The supporting boss 223 is located on the first support base 220 and avoids the first connecting area 22A and the area where the second support plate 260 is located. When the second support base 240 is embedded in the embedding hole 221, the top surface of the second support plate 260, the top surface of the first support plate 250 and the top surface of the supporting boss 223 are coplanar and are spaced apart, so as to support different areas of the material, thereby further improving the supporting stability of the secondary lifting structure 200 and the lifting device to the material.

[0044] In this embodiment, as shown in FIG. 6, the first support plate 250 is provided with a plurality of first connecting areas 25A, and each first connecting area 25A is provided with a fifth connecting hole 251. Some or all of the first connecting areas 25A are used as first effective areas, and the first support plate 250 corresponds to each first effective area. The first support plate 250 is provided with a sixth connecting hole 252, and the sixth connecting hole 252 is detachably connected to the fifth connecting hole 251 by a first connecting member. One of the fifth connecting hole 251 and the sixth connecting hole 252 is a waist-shaped hole extending along the length direction of the first support plate 250. Figure 1As shown, the bottom of the first bracket 220 is fixedly connected with a bracket arm 270, the bracket arm 270 is connected to the stand plate 100 through a vertical guide structure 280 at one end of the stand plate 100, and the second lifting assembly 230 is fixedly connected to the bracket arm 270. On the one hand, in the process that the first lifting assembly 210 drives the first bracket 220 to drive the second lifting assembly 230 and the second bracket 240 to move vertically, the vertical guide structure 280 can guide the vertical movement of the first bracket 220, thereby improving the accuracy of the secondary lifting structure 200 supporting the lifting movement of the material. On the other hand, the bracket arm 270 extends away from the stand plate 100, and the extension length is greater than half the length of the first bracket 220, and the second lifting assembly 230 is directly connected to the bracket arm 270. The bracket arm 270 can support the middle region of the first bracket 220 and the second lifting assembly 230, so as to reduce the torque applied to the connection between the first bracket 220 and the stand plate 100 by the material, the second lifting assembly 230 and the second bracket 240, thereby reducing the load of the first bracket 220, and ensuring the stability and accuracy of the first bracket 220 and the second bracket 240 supporting the material.

[0045] Specifically, the bracket arm 270 can include a vertical arm body 271 and a horizontal arm body 272, the vertical arm body 271 is fixedly connected to the vertical guide structure 280, the horizontal arm body 272 is connected to the top end of the vertical arm body 271 and the bottom of the first bracket 220, and an inclined reinforcing arm body 273 is connected between the bottom end of the vertical arm body 271 and the horizontal arm body 272, so as to ensure the strength of the bracket arm 270 and the stability of supporting the first bracket 220 and the second lifting assembly 230.

[0046] Specifically, in the embodiment, the bracket arm 270 is two, and is supported on opposite sides of the embedded hole 221. The two bracket arms 270 support the first bracket 220 on both sides, and carry the second lifting assembly 230 on both sides, thereby further improving the stability of supporting the first bracket 220 and the second lifting assembly 230 by the bracket arm 270.

[0047] In the embodiment, as shown in FIG. 1, the bracket arm 270 is connected to the vertical guide structure 280 through a horizontal flange 274, and the horizontal flange 274 is fixedly connected to the vertical guide structure 280.
