[0024] The following specific embodiments are only explanations of the present invention, and they are not limitations of the present invention. Those skilled in the art can make modifications without creative contributions to this embodiment after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0025] Example 1, as Figure 1 shown, a C-type continuous elevator loading platform includes a loading platform main body and upper and lower turning mechanisms respectively connected to the left and right sides at the front end of the loading platform main body 1. The upper and lower turning mechanism 2 includes a turning plate a connected to the loading platform main body 1. Through the design of the turning plate a, the loading platform main body 1 can be turned.

[0026] The turning plate a is rotatably connected to the loading platform main body 1. Specifically, the turning plate a includes an inner vertical plate a1 rotatably connected to the loading platform main body 1, an outer vertical plate a2 for connecting the outer chain, and a transverse connecting plate a3 connected between the inner vertical plate a1 and the outer vertical plate a2. The inner vertical plate a1, the outer vertical plate a2 and the transverse connecting plate a3 are integrally connected, and can be realized through processes such as integral casting, forging, and welding. For example, the turning plate a is a steel casting plate, which has good toughness and impact resistance, and helps to stably turn and convey. Therefore, the turning plate a is in a U-shaped state.

[0027] The loading platform main body 1 specifically includes: a front support link 11 and a rear support link 12 distributed front and rear. The loading platform main body 1 further includes a left inner chain 13 and a right inner chain 14 connected between the front support link 11 and the rear support link 12, and a plurality of loading plates 15 connected between the left inner chain 13 and the right inner chain 14. The loading plates 15 can be made of aluminum alloy plates. Both the left inner chain 13 and the right inner chain 14 are pallet chains, that is, chains that can be turned 90 degrees, and the chain links are in a square-shaped structure, which is more common in the prior art and will not be elaborated here.

[0028] Both the left and right ends of the front support link 11 are connected with mounting seats b for mounting the flip plate a. The mounting seat b is in a U-shaped groove structure with an opening facing forward. The mounting seat b has a rotating space for the inner vertical plate a1 to rotate up and down, and a central axis b0 extending in the left-right direction is installed at this rotating space. That is, the U-shaped groove of the mounting seat b with an opening facing forward is the rotating space, and the U-shaped groove is open at the top, bottom, and front, so that the inner vertical plate a1 can be flipped 180 degrees up and down. This makes the entire cargo platform body 1 more smooth during C-shaped deformation flipping and not prone to failure. The axial direction of the central axis b0 is also along the left-right direction, and the central axis b0 passes through the U-shaped side plates on both sides of the mounting seat b and the inner vertical plate a1 for installation, so that the inner vertical plate a1 can be flipped, and thus the entire flip plate a can be flipped.

[0029] The above-mentioned cargo platform body 1 is driven by 4 external chains. Both ends of the rear support link 12 are connected to two chains, and the flip plates a on both left and right sides are connected to two outer chains. The first outer connection holes a201 for connecting with the chains are opened on the outer vertical plates a2, and the second outer connection holes a202 for connecting with the chains are also opened at both ends of the rear support link 12. The chains connected to the outer vertical plates a2 are called the first outer chains, and the chains connected to the second outer connection holes a202 are called the second outer connection strips. The connection with the chains can be axially connected through a pin shaft or a bolt structure.

[0030] The structure has two flip plates that can rotate 180 degrees. When the cargo platform is operating horizontally for shipping, the U-shaped flip plate flips to avoid the internal structures such as the horizontally driven chains, and then the whole is flipped to change the direction of the cargo platform to achieve continuous C-direction transportation with the import and export in the same direction.

[0031] Embodiment 2, as Figure 2 shown, a circulating chain structure of a hoist includes a cargo platform and two chains are connected to both the left and right sides of the cargo platform, namely the first outer chain c1 and the second outer chain c2. The left-right spacing between the first outer chain c1 on the same side and the cargo platform is farther than that between the second outer chain c2 on the same side. Through the design of the four chains, the cargo platform can better achieve C-shaped transportation and flipping operations, and the cargo platform can adopt the structural design of the cargo platform in Embodiment 1. The second outer chain c2 is more outboard in the left-right direction than the first outer chain c1. Thus, the interference between the chains and the internal components between the chains and the hoist can be further reduced.

[0032] Further, flip plates a are connected to both the left and right ends of the front side of the cargo platform. The left and right flip plates a are respectively installed and connected to the left and right first outer chains c1. The outer vertical plate a2 is provided at the position of the flip plate a near the outside of the cargo platform, and the outer vertical plate a2 is installed and connected to the first outer chain c1. The rear side of the cargo platform is provided with a rear support link 12, and the left and right ends of the rear support link 12 are respectively connected to the left and right second outer chains c2.

[0033] The specific distribution of the chains can be as follows: The first outer chain c1 includes a first front up-and-down extension section c11 near the front side of the elevator, a first lower front-and-back extension section c12 extending backward connected to the lower end of the first front up-and-down extension section c11, a first rear up-and-down extension section c13 near the rear side of the elevator connected to the rear end of the first lower front-and-back extension section c12, and a first upper front-and-back extension section c14 connected to the front end of the first rear up-and-down extension section c13 and connected to the upper end of the first front up-and-down extension section c11. The first outer chain c1 forms a relatively square-shaped loop structure, enabling the flip plate to be turned and transported better. The second outer chain c2 includes two second up-and-down extension sections c21 distributed front and back near the rear side of the elevator, and the upper ends of the two second up-and-down extension sections c21 are connected. A V-shaped connection section c22 with an opening facing backward is connected between the lower end of the front second up-and-down extension section c21 and the lower end of the rear second up-and-down extension section c21. Both of the two second up-and-down extension sections c21 are near the rear side of the elevator, making the overall structure an L-shaped structure, thereby further improving the use effect. Further, the lower end of the front second up-and-down extension section c21 is higher than the lower end of the second up-and-down extension section c21.

[0034] Steering components are provided at the corner positions of the first outer chain c1 and the second outer chain c2. The steering components can be components such as steering wheels installed on the elevator. In addition, ordinary figure-eight chains can be used for both the first outer chain c1 and the second outer chain c2.

[0035] Example 3, as Figure 3As shown in the figure, a transition structure of a hoist includes a front conveying roller d1 and a rear conveying roller d2 for installation on the hoist. A passage interval d12 for the loading platform to pass up and down is formed at an interval between the front conveying roller d1 and the rear conveying roller d2. The transition structure further includes a horizontal mounting beam d3 for installation on the hoist, and vertical guiding wheels d4 for guiding the up and down movement of the loading platform are mounted on the horizontal mounting beam d3. In this solution, the loading platform is a deformable and flipable one. When the goods enter and exit the hoist through the front conveying roller d1 and the rear conveying roller d2, after the goods are output from the loading platform, the loading platform can move up and down through the passage interval d12, or the loading platform first moves up and down through the passage interval d12 and then horizontally flips and deforms to receive the goods conveyed in. This can prevent the goods from easily falling from the large interval between the conveying rollers at the existing exit position. In this solution, with the cooperation of the vertical guiding wheels d4, the effective up and down movement of the loading platform is ensured.

[0036] Preferably, first sprockets d5 are installed on the same side (left and right) of the front conveying roller d1 and the rear conveying roller d2, and a first drive chain d51 is wound around these two first sprockets d5, so that these two rollers run synchronously.

[0037] The transition structure further includes a third sprocket d7 and a second sprocket d6 connected to the rear conveying roller d2. A second drive chain d52 is wound around the third sprocket d7 and the second sprocket d6, and the third sprocket d7 is installed on a drive roller shaft d8. A fourth sprocket 8 for driving the chain for driving the loading platform to operate is installed on the drive roller shaft d8. First, it is driven by the drive roller shaft d8. Second, the synchronous operation of the loading platform and the conveying rollers can be maintained. The chains for driving the loading platform to operate refer to structures such as the first outer chain c1 and the second outer chain c2. Of course, the loading platform in this embodiment can adopt the structure of the loading platform in the previous embodiment.

[0038] Further optimized, two relatively arranged upper L-shaped support plates d31 are fixedly installed on the upper side of the horizontal mounting beam d3, and at least two of the vertical guiding wheels d4 are arranged vertically on the upper L-shaped support plates d31. Two relatively arranged lower L-shaped support plates d32 are fixedly installed on the lower side of the horizontal mounting beam d3, and at least one of the vertical guiding wheels d4 is installed on the lower L-shaped support plates d32.

[0039] A C-type hoist includes the aforementioned transition structure of a hoist and further includes a loading platform. The loading platform can adopt the structure of the previous embodiment. Among them, the loading platform has a left inner chain 13 and a right inner chain 14 distributed left and right. Further, the vertical guiding wheels d4 on the left and right sides respectively abut against the left inner chain 13 and the right inner chain 14 front and rear, making the operation of the loading platform more stable and reliable.

[0040] For the C-type elevator mentioned in this application, the C-type operation of the loading platform is reversible, that is, it can rotate clockwise or counterclockwise, as long as the traveling direction of the outer chain connected to the loading platform is changed.

[0041] Example 4, as Figure 4 、 5 shown, a hoist frame structure includes a frame e1 that surrounds to form a rectangular structure in the front, back, left, and right. The adjacent frames e1 are connected by corner strengthening connectors e2. The corner strengthening connector e2 includes a first strengthening plate e21 and a second strengthening plate e22 that are integrally connected in a vertical shape. One side of the first strengthening plate e21 away from the second strengthening plate e22 is integrally connected with a first L-shaped mounting plate e31 for inserting and fixedly connecting one end of the frame e1 on the same side as the first strengthening plate e21. One side of the second strengthening plate e22 away from the first strengthening plate e21 is integrally connected with a second L-shaped mounting plate e32 for inserting and fixedly connecting one end of the frame e1 on the same side as the second strengthening plate e22. For the structural strengthening of the corners, more hoist frame structures can be stacked, increasing the transportation height, and the fixing method can adopt existing methods such as welding or screwing.

[0042] Preferably, an inner strengthening beam e4 located inside the frame e1 is also fixedly connected between the first L-shaped mounting plate e31 and the second L-shaped mounting plate e31 on the same side to strengthen the internal structure. The inner strengthening beam e4 is a U-shaped plate structure with an opening facing the horizontal direction. Further, the inner strengthening beam e4 includes inner strengthening upright plates e41 fixedly connected to the first L-shaped mounting plate e31 and the second L-shaped mounting plate e31, and inner upper strengthening plates e42 and inner lower strengthening plates e43 integrally connected to the upper and lower sides of the inner strengthening upright plates e41 respectively.

[0043] U-shaped suspension support beams e5 with openings facing outwards are also connected to the inner lower strengthening plates e43 of the inner strengthening beams e4 on the left and right sides.

[0044] The structures of the inner strengthening beam e4 and the U-shaped suspension support beam e5 are used to improve the strength of the frame, and can also be well used to install other internal support, guiding, beam-column and other structures.

[0045] Support columns e6 extending in the up and down direction are installed on the front and rear sides of the U-shaped suspension support beam e5. The support columns e6 are used to combine with other beam-columns inside the hoist and can be used to install structures such as motors and improve the structural strength.

[0046] Further, adjacent inner reinforcing beams e4 are connected by an inner corner connector e7. The inner corner connector e7 includes a lower reinforcing connecting plate e71 fixedly connected to adjacent inner lower reinforcing plates e43 respectively, and a first inner vertical reinforcing connecting plate e72 and a second inner vertical reinforcing connecting plate e73 integrally connected to the outer edge of the lower reinforcing connecting plate e71 and respectively connected to adjacent inner reinforcing vertical plates e41. The lower reinforcing connecting plate e71 has an L-shaped structure with a rounded inner side, and the outer side of the lower reinforcing connecting plate e71 has a chamfered structure, and at the chamfer, there is integrally connected a middle vertical connecting plate e74 in an upright shape and horizontally connected to the first inner vertical reinforcing connecting plate e72 and the second inner vertical reinforcing connecting plate e73 on both sides respectively.

[0047] In addition, a mesh e8 is installed on the frame e1 to strengthen the protection of the side part, and also to observe the internal operation conditions, so as to facilitate timely problem discovery and improve safety.

[0048] A C-type hoist includes a hoist frame structure of this embodiment.

[0049] Example 5, as Figure 6 shown, a C-type hoist includes an outer frame, the outer frame is stacked up and down by several frame structures, a loading platform is installed in the outer frame, and two chains are respectively connected to the left and right sides of the loading platform, namely a first outer chain c1 and a second outer chain c2. The left and right spacing between the first outer chain c1 on the same side and the loading platform is farther than that between the second outer chain c2 on the same side. A transition structure for the loading platform to transfer goods at the inlet and outlet is also installed in the outer frame. Through the design of the frame and the structural design of the internal loading platform and chains, and in cooperation with the transition structure, the hoist structure can better convey goods, making the conveying smoother and more stable.

[0050] The frame structure, chain structure, loading platform, and transition structure can all adopt the structures of the foregoing embodiments.

[0057] On the lower side of the horizontal mounting beam d3, two relatively arranged lower L-shaped support plates d32 are fixedly installed, and at least one of the vertical guide wheels d4 is installed on the lower L-shaped support plates d32.

[0058] The frame structure includes a frame e1 that surrounds to form a rectangular structure in the front, rear, left, and right directions. Adjacent frames e1 are connected by corner strengthening connectors e2. The corner strengthening connectors e2 are integrally formed by a first strengthening plate e21 and a second strengthening plate e22 in a perpendicular shape.
