[0034] The features and exemplary embodiments of various aspects of the present application will be described in detail below with reference to the drawings. The following detailed description is merely intended to explain the present application, and is not intended to limit the present application. The present application can be implemented without some of the specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by showing examples of the present application.

[0035] As Figures 1 to 12As shown, the embodiment of the present application provides a hoisting system, which comprises: a hoisting device 10 comprising a vehicle frame 11 and at least two hoisting mechanisms 12, the at least two hoisting mechanisms 12 being movably connected to the vehicle frame 11 along a first direction X and being arranged at intervals in the first direction X; at least two material cages 20, the material cage 20 being configured to load a photovoltaic array semi-finished product 100, the photovoltaic array semi-finished product 100 comprising a plurality of photovoltaic panels 101; a first material cage of the at least two material cages 20 being located at a discharging station 31 of the photovoltaic array semi-finished product 100 and loaded with at least one photovoltaic array semi-finished product 100, and a second material cage of the at least two material cages 20 being located at a loading station 32 of a transport vehicle and being in an empty state; wherein the at least two hoisting mechanisms 12 are configured to simultaneously hoist the at least two material cages 20, and are configured to hoist the first material cage to the loading station 32 and hoist the second material cage to the discharging station 31.

[0036] In the embodiment of the present application, as shown, Figure 1 The material loaded in the material cage 20 is a photovoltaic array semi-finished product 100, which comprises a plurality of photovoltaic panels 101 arranged in a certain form, and the plurality of photovoltaic panels 101 are fixed together via a fixing structure, which comprises but is not limited to at least one connecting beam arranged on the back of the photovoltaic panel. In some embodiments, the connecting beam comprises a plurality of purlins 102 and a plurality of diagonal beams 103, the plurality of purlins 102 are arranged at intervals and in parallel, the plurality of diagonal beams 103 are arranged at intervals and in parallel, the purlin 102 intersects with the diagonal beam 103 and is superimposed to form a frame, and the plurality of photovoltaic panels 101 are installed on the side of the purlin 102 away from the diagonal beam 103 to form a photovoltaic array semi-finished product. In other embodiments, the connecting beam can comprise a main shaft capable of rotating the photovoltaic panel 101 therearound.

[0037] The assembly of the photovoltaic array semi-product 100 can be performed in a factory to ensure installation accuracy and installation efficiency, for example, a plurality of photovoltaic panels 101 and their fixing structures can be assembled in the form of a flow line, and the specific assembly method of the photovoltaic array semi-product 100 is not limited in the present application. After the assembly is completed and the complete photovoltaic array semi-product 100 is formed, at least one photovoltaic array semi-product 100 is transported to the unloading station 31 of the hoisting system, and is loaded into the cage 20 at the unloading station 31, so that the cage 20 can form a first cage with at least one photovoltaic array semi-product 100. For example, an additional hoisting system can be used to load the photovoltaic array semi-product 100 at the unloading station 31, and the specific unloading method of the photovoltaic array semi-product 100 is not limited in the present application. After the hoisting operation of the hoisting equipment 10, the first cage is hoisted to the loading station 32, and a transport vehicle is parked at the loading station 32. The first cage is specifically hoisted to the transport vehicle for loading, and the photovoltaic array semi-product 100 in the first cage is transported to the installation site after being loaded into the transport vehicle. Among them, in some embodiments, the empty cage, i.e. the second cage, is loaded on the transport vehicle parked at the loading station 32, and the hoisting equipment 10 is also used to directly or indirectly hoist the second cage to the unloading station 31, so that the transport vehicle is emptied to load the cage containing at least one photovoltaic array semi-product 100, for example, the above-mentioned first cage; in addition, the empty cage is placed at the unloading station 31, and new photovoltaic array semi-products can be continuously loaded.

[0038] As Figure 2 and Figure 3As shown, the hoisting system of the embodiment of the present application comprises a hoisting device 10 and at least two material cages 20, the material cages 20 are capable of loading photovoltaic array semi-finished products 100 comprising a plurality of photovoltaic panels 101, the material cages 20 comprise the first material cage and the second material cage, and optionally, can further comprise other spare empty material cages, and / or material cages located at other stations, to be transported, and loaded with at least one photovoltaic array semi-finished product. The hoisting device 10 comprises a vehicle frame 11 and at least two hoisting mechanisms 12, the at least two hoisting mechanisms 12 are movably connected to the vehicle frame 11 along the first direction X, specifically, the vehicle frame 11 comprises a sliding guide extending along the first direction X above each station of the hoisting system, so that the hoisting mechanisms 12 can be moved on the vehicle frame along the extension direction of the sliding guide to accurately reach the positions of different stations; the sliding tracks of these hoisting mechanisms are the same, and one hoisting mechanism 12 cannot slide above another hoisting mechanism 12; preferably, the hoisting device 10 comprises two hoisting mechanisms 12, thereby shortening the length of the vehicle frame 11 and simplifying the design of the hoisting system. Further, the at least two hoisting mechanisms 12 are capable of simultaneously hoisting at least two material cages 20 to move on the vehicle frame 11 along the first direction X, for example but not limited to, capable of simultaneously hoisting the first material cage and the second material cage, or capable of simultaneously hoisting one of the first material cage and the second material cage and other material cages.

[0039] It should be noted that the simultaneous hoisting here refers to that there is a moment when the at least two material cages 20 are simultaneously hoisted on the at least two hoisting mechanisms 12, but the hoisting operation and the lowering operation of the at least two material cages 20 do not necessarily occur simultaneously. In addition, it can be understood that the hoisting device of the present application can comprise three or more hoisting mechanisms 12, which can be configured to simultaneously hoist three or more material cages 20, and capable of hoisting the first material cage to the loading station 32 and hoisting the second material cage to the unloading station 31.

[0040] For example, after one hoisting mechanism 12 hoists the first material cage from the unloading station 31, it can move along the first direction X, thereby making the first material cage leave the unloading station 31; at the same time, the other hoisting mechanism 12 can hoist an empty material cage 20, for example, the second material cage or other spare empty cage, and also can move along the first direction X, thereby placing the empty material cage 20 at the unloading station 31 without being disturbed by the first material cage. For another example, after one hoisting mechanism 12 hoists the second material cage from the loading station 32, it can move along the first direction X, thereby making the second material cage leave the loading station 32; at the same time, the other hoisting mechanism 12 can hoist a material cage loaded with at least one photovoltaic array semi-finished product, for example, the first material cage or other material cage, and also can move along the first direction X, thereby placing the material cage loaded with at least one photovoltaic array semi-finished product at the loading station 32 without being disturbed by the second material cage.

[0041] Therefore, the hoisting system of the embodiment of the present application improves the synchronous hoisting quantity of the material cages 20, avoids the mutual interference between the material cages 20 in different stations, and improves the unloading and loading rhythm of the photovoltaic array semi-finished products 100, thereby improving the loading and transportation rhythm of the photovoltaic array semi-finished products 100 in the material cages 20 and improving the overall efficiency.

[0042] As shown in Figure 2 The hoisting system of the embodiment of the present application, wherein the vehicle frame 11 is arranged on both sides of the at least two material cages 20 in the first direction X, and the width of the vehicle frame 11 in the first direction X is at least 3 times the width of the material cage 20 in the first direction X.

[0043] In specific implementation, the vehicle frame 11 is arranged on both sides of the at least two material cages 20 in the first direction X, and the plurality of hoisting mechanisms 12 can slide on the vehicle frame 11 in the first direction X, and the sliding range of the plurality of hoisting mechanisms 12 in the first direction X can cover all the material cages 20, so that the plurality of hoisting mechanisms 12 can hoist any material cage 20, thereby ensuring the hoisting flexibility of the hoisting system.

[0044] In addition, the width of the vehicle frame 11 in the first direction X is at least 3 times the width of the material cage 20 in the first direction X, that is, there is a sliding space of at least one material cage width in the first direction X when each hoisting mechanism 12 hoists the material cage 20. In one example, the hoisting device 10 includes two hoisting mechanisms, and can simultaneously hoist two material cages 20. The width of the vehicle frame 11 in the first direction X is 3 times the width of the material cage 20 in the first direction X, and each hoisting mechanism can have a sliding space of about one material cage width. Thus, when the hoisting device 10 simultaneously hoists two material cages 20, a rotating space can be provided to prevent interference between the material cages 20. In another example, the hoisting device 10 includes three hoisting mechanisms 12, and can simultaneously hoist three material cages 20. The width of the vehicle frame 11 in the first direction X is 5 times the width of the material cage 20 in the first direction X, and each hoisting mechanism can have a sliding space of about two material cage widths. In yet another example, the hoisting device 10 includes four hoisting mechanisms 12, and can simultaneously hoist four material cages 20. The width of the vehicle frame 11 in the first direction X is 6 times the width of the material cage 20 in the first direction X, and each hoisting mechanism 12 can have a sliding space of about two material cage widths. The width of the vehicle frame 11 in the first direction X allows at least two material cages 20 to be simultaneously hoisted by at least two hoisting mechanisms 12 and transferred, thereby improving the hoisting efficiency. In addition, the vehicle frame 11 does not need to move in the first direction X, thereby simplifying the design of the vehicle frame 11.

[0045] In some optional embodiments, the vehicle frame 11 is configured to be movable in a second direction Y, and the second direction Y intersects the first direction X. For example, the first direction X is perpendicular to the second direction Y.

[0046] In particular embodiments, the vehicle frame 11 is configured to be movable in the second direction Y, so as to drive the lifting mechanism 12 to move in the second direction Y, and thus to align the lifting mechanism 12 with the desired work station to be reached, thereby ensuring the flexibility of the lifting system as a whole, especially when the unloading work station 31 and the loading work station 32 are arranged in the second direction.

[0047] In particular, the lifting system can further comprise two guide rails 40 arranged in the first direction X and spaced apart between the two sides of the at least two cages 20, both of the two guide rails 40 extending in the second direction Y, and the vehicle frame 11 is slidably mounted on the two guide rails 40 in the second direction Y, so that the two guide rails 40 guide the movement of the vehicle frame 11, and thus ensure the accuracy of the movement direction of the vehicle frame 11 and the lifting mechanism 12, thereby enabling the lifting mechanism 12 to align with the desired work station to be reached in the second direction Y.

[0048] In some alternative embodiments, the lifting system of the present application, wherein the unloading work station 31 and the loading work station 32 are arranged in the second direction Y; the at least two lifting mechanisms 12 are configured to lift the first cage directly or via the first work station 33 to the loading work station 32, and to lift the second cage directly or via the second work station 34 to the unloading work station 31; wherein the first work station 33 is arranged on the first side of the unloading work station 31 and the loading work station 32 in the first direction X, and the second work station 34 is arranged on the second side of the unloading work station 31 and the loading work station 32 in the first direction X. Direct lifting of the first cage to the loading work station 32 means that the first cage is lifted by the lifting mechanism 12 and then directly lifted to the loading work station 32; lifting of the first cage to the loading work station 32 via the first work station 33 means that the first cage is first lifted by the lifting mechanism 12 to the first work station 33, and then lifted from the first work station 33 to the loading work station 32 after a certain period of time, and the same applies to the second cage.

[0049] The first work station 33 for the first cage and the second work station 34 for the second cage can be provided simultaneously or alternatively. In the case of simultaneous provision of the first work station 33 and the second work station 34, preferably, the first side and the second side are opposite sides, the first side being specifically the lower side in the first direction X, and the second side being specifically the upper side in the first direction X, which can simplify the system design and maximize the lifting efficiency.

[0050] In the present application, the first work station 33 is provided so that the first cage of the unloading work station 31 does not have to wait for the transport vehicle and is temporarily stored in the first work station 33 when the transport vehicle has not returned to the loading work station 32; and the second work station 34 is provided so that the second cage does not have to wait for the unloading work station 31 to be empty and is temporarily stored in the second work station 34.

[0051] exist Figure 3 and Figure 4 In the illustrated embodiment, the lifting equipment 10 includes two lifting mechanisms 12, capable of simultaneously lifting two material cages 20, as an example. The width of the frame 11 in the first direction X is approximately three times the width of the material cage 20 in the first direction X, and each lifting mechanism has a sliding space approximately the width of one material cage. Figure 3 In the first embodiment shown, the unloading station 31 and the loading station 32 are arranged along the second direction Y. At least two lifting mechanisms 12 are capable of directly lifting the first material cage from the unloading station 31 to the loading station 32, and directly lifting the second material cage from the loading station 32 to the unloading station 31. It should be noted that... Figure 3 The loading and unloading station 31 and the loading station 32 each have two dashed frame structures on the first and second sides of the first direction X. These dashed frame structures represent the operating positions of the lifting mechanism 12, not the actual work positions. They are only used to illustrate the operating positions of the two lifting mechanisms 12. The material cage 20 will not be placed in this position.

[0052] exist Figure 3 The specific hoisting process in the first embodiment shown is as follows: the first hoisting mechanism 12, i.e. Figure 3 The upper and middle lifting mechanisms and the second lifting mechanism 12 are... Figure 3 The lower and middle lifting mechanisms move to the loading station 32 and the first side of the loading station 32, respectively. The first lifting mechanism 12 lifts the second material cage on the loading station 32. The first lifting mechanism 12 and the second lifting mechanism 12 move along the first direction X to the second side of the loading station 32 and the loading station 32. The frame 11 moves along the second direction Y, so that the first lifting mechanism 12 and the second lifting mechanism 12 move along the second direction Y to the second side of the unloading station 31 and the unloading station 31. The second lifting mechanism 12 lifts the first material cage at the unloading station 31. At this time, the first material cage and the second material cage are lifted at the same time. The first lifting mechanism 12 and the second lifting mechanism 12 move along the first direction X to the unloading station 31 and the running position on the first side of the unloading station 31. The first lifting mechanism 12 places the second material cage at the unloading station 31. The frame 11 moves along the second direction Y, so that the first lifting mechanism 12 and the second lifting mechanism 12 move along the second direction Y to the loading station 32 and the running position on the first side of the loading station 32. The first lifting mechanism 12 and the second lifting mechanism 12 move along the first direction X to the running position on the second side of the loading station 32 and the loading station 32. The second lifting mechanism 12 places the first material cage at the loading station 32, thereby completing the complete lifting process.

[0053] Although Figure 3The illustrated embodiment uses the simultaneous lifting of two material cages 20 by two lifting mechanisms 12 as an example. However, it is understood that under the same concept, more lifting mechanisms 12 can be set to lift more material cages 20 simultaneously. For example, two unloading stations 31 and two loading stations 32 can be set along the first direction X. Each unloading station 31 and each loading station 32 are arranged along the second direction Y. The vehicle frame can include four lifting mechanisms 12, and the width of the vehicle frame along the first direction X can be approximately the width of six material cages. The specific lifting process is as follows... Figure 3 The embodiments shown are similar and will not be described again here.

[0054] exist Figure 4 In the second embodiment shown, the unloading station 31 and the loading station 32 are arranged along the second direction Y. Two lifting mechanisms 12 are capable of lifting a first material cage from the unloading station 31 via a first station 33 to the loading station 32, and lifting a second material cage from the loading station 32 via a second station 34 to the unloading station 31. The first station 33 is located on a first side of the unloading station 31 and the loading station 32 in the first direction X, and the second station 34 is located on a second side of the unloading station 31 and the loading station 32 in the first direction X. The lifting system also includes a spare material cage located at a spare station 35 and in an unloaded state. The spare station 35 is located on the second side of the unloading station 31, and the two lifting mechanisms 12 are further configured to lift the spare material cage to the unloading station 31.

[0055] exist Figure 4 In the middle, the second side of the unloading station 31 is the spare station 35, the second side of the loading station 32 is the second station 34, and the first side of the unloading station 31 and the loading station 32 are respectively set with two first stations 33.

[0056] exist Figure 4 In the second embodiment shown, the specific hoisting process is as follows: before the transport vehicle returns to the loading position, the first hoisting mechanism 12... Figure 4 The upper and middle lifting mechanisms and the second lifting mechanism 12 are... Figure 4The middle and lower side lifting mechanisms respectively run to the standby station 35 and the unloading station 31, and respectively lift the standby cage of the standby station 35 and the first cage of the unloading station 31; the first lifting mechanism 12 and the second lifting mechanism 12 run to the unloading station 31 and the first station 33 on the first side of the unloading station 31 along the first direction X, and respectively place the standby cage and the first cage in the unloading station 31 and the first station 33; after being placed, the standby cage in the unloading station 31 can be filled with materials. At this time, the first station 33 on the first side of the loading station 32 can have been placed with the first cage filled with the photovoltaic array semi-finished product; and the second station 34 can also be placed with the standby cage, and the first lifting mechanism 12 can lift the standby cage in the second station 34 to the standby station 35. In the case that the transport vehicle returns to the loading station, the frame 11 moves along the second direction Y, so that the first lifting mechanism 12 and the second lifting mechanism 12 run to the loading station 32 and the first station 33 on the first side of the loading station 32; the first lifting mechanism 12 lifts the second cage in the loading station 32, and the second lifting mechanism 12 lifts the first cage in the first station 33, and both move to the first side along the first direction X, so that the first lifting mechanism 12 and the second lifting mechanism 12 respectively move to the second station 34 and the loading station 32; the first lifting mechanism 12 and the second lifting mechanism 12 respectively place the second cage and the first cage in the second station 34 and the loading station 32, at this time, the first cage of the loading station can be operated for loading; the second lifting mechanism 12 can lift the first cage of the first station 33 on the first side of the unloading station 31 to the first station 33 on the first side of the loading station 32, thereby completing the complete lifting process. In this embodiment, the unloading rhythm of the photovoltaic array semi-finished product is relatively fast, so the standby cage in the standby station 35 and the second station 34 and the two first stations 33 on the first side of the unloading station 31 and the loading station 32 are used. As a variation of the embodiment, if the unloading and loading operation rhythm difference is not large, only the standby cage in the standby station 35 can be used, that is, the standby station 35 and the second station 34 are the same station, or only one first station 33 can be used; or more standby stations 35, second stations 34, more first stations 33 can be used according to specific needs.

[0057] Although Figure 4 Although the embodiment in the above description takes two lifting mechanisms 12 that can simultaneously lift two cages as an example, it can be understood that under the same concept, the frame 11 can include more lifting mechanisms 12 to be able to simultaneously lift three or more cages 20, and the specific standby station 35, first station 33, second station 34, etc. and the specific lifting process can be set according to needs.

[0058] According to the above hoisting process, the setup of the first station 33, the second station 34 and the standby station 35 enables at least three material cages 20 to rotate synchronously, allowing at least one of the unloading station 31 and the loading station 32 to carry the material cage 20 for unloading or loading. This allows the hoisting mechanism 12 to perform the unloading or loading steps synchronously during the hoisting process, thereby improving the overall efficiency of loading and unloading materials and hoisting.

[0059] It should be noted that the hoisting process in the first and second embodiments is a counterclockwise hoisting process, but the direction can also be reversed to a clockwise hoisting process.

[0060] In some alternative embodiments, at least two lifting mechanisms 12 are capable of directly lifting the first material cage from the unloading station 31 to the loading station 32, and lifting the second material cage from the loading station 32 to the unloading station 31 via the second station 34.

[0061] In some alternative embodiments, at least two lifting mechanisms 12 are capable of lifting the first cage from the unloading station 31 through the first station 33 to the loading station 32, and lifting the second cage directly from the loading station 32 to the unloading station 31.

[0062] In both of the above embodiments, a spare workstation 35 can also be set up to enable at least three material cages 20 to rotate within the hoisting system.

[0063] like Figure 5 As shown, in some other embodiments of this application, the unloading station 31 and the loading station 32 are arranged along the first direction X. In one example, the vehicle frame includes two lifting mechanisms 12, and a lifting space 36, approximately the width of a material cage, is provided on one side of the unloading station 31 and the loading station 32 in the first direction X. The vehicle frame spans across both sides of the unloading station 31, the loading station 32, and the lifting space 36.

[0064] In a specific implementation, the first lifting mechanism 12 lifts the first cage at the unloading station 31, and the second lifting mechanism 12 lifts the second cage at the loading station 32. After the two cages are lifted simultaneously, the two lifting mechanisms 12 move along the first direction X, and the second lifting mechanism 12 drives the second cage to the lifting space 36. The first lifting mechanism 12 places the first cage at the loading station 32. After the transport vehicle carries the first cage and leaves, the two lifting mechanisms 12 move reversely along the first direction X. The second lifting mechanism 12 places the second cage at the loading station 32, and the first lifting mechanism 12 lifts the second cage and places it at the unloading station 31. In another example, the lifting space 36 is arranged on both sides of the unloading station 31 and the loading station 32. In this way, the second lifting mechanism 12 can directly place the second cage at the unloading station 31 without being exchanged to the first lifting mechanism 12. In yet another example, similar to the above embodiment, the standby station 35, the first station 33, and the second station 34 can also be arranged in the second direction Y.

[0065] Although Figure 5 Although the above embodiment illustrates that the two lifting mechanisms 12 can simultaneously lift two cages 20, it can be understood that, under the same concept, the vehicle frame 11 can include more lifting mechanisms 12 to simultaneously lift three or more cages 20, for example, multiple unloading stations 31 and multiple loading stations 32 are arranged in the first direction X.

[0066] As Figure 2 and Figures 6 to 9 shown, the lifting system of the embodiment of the present application, wherein the lifting mechanism 12 includes a lifting tool 13 and a connecting piece 14, the connecting piece 14 is used to movably connect the lifting tool 13 to the vehicle frame 11, the lifting tool 13 is used to lift the cage 20 and includes a support plate 131 and a locking piece 132 arranged on the support plate 131, the locking piece 132 has a locking block 1321 which is rotatable and in a strip block structure; the cage 20 has a matching piece 21 corresponding to the locking piece 132, the matching piece 21 is hollow inside and has a matching hole 211 penetrating through the wall thereof, the matching hole 211 is in a strip hole structure matched with the locking block 1321, and the locking block 1321 is configured to be rotatable inside the matching piece 21 to be fixedly connected to the matching piece 21.

[0067] In specific implementation, the lifting tool 13 of the lifting mechanism 12 is movably connected to the trolley frame 11 through the connecting piece 14, the lifting tool 13 comprises a support plate 131 and a locking piece 132 arranged on the support plate 131, the material cage 20 is provided with a matching piece 21 corresponding to the locking piece 132, the matching piece 21 is internally hollow and is provided with a matching hole 211 penetrating through the wall thereof, the locking block 1321 of the strip-shaped block structure of the locking piece 132 can enter the internal space of the matching piece 21 through the matching hole 211 of the strip-shaped hole structure, and the extending direction of the locking block 1321 is the same as that of the matching hole 211 during the entering process; after entering the internal space of the matching piece 21, the locking block 1321 can be rotated to make the extending direction of the locking block 1321 intersect with the extending direction of the matching hole 211, in this state, the locking block 1321 cannot be separated from the matching hole 211, thereby realizing the fixation between the locking piece 132 and the matching piece 21, and further realizing the fixation between the lifting tool 13 and the material cage 20. During the process that the lifting tool 13 of the lifting mechanism 12 hoists and moves the material cage 20 to different work stations, the relative movement between the material cage 20 and the lifting tool 13 does not occur, thereby enabling the material cage 20 to accurately reach the corresponding position to complete the unloading and loading operations, and ensuring the overall work efficiency.

[0068] Optionally, the locking piece 132 can have two rotatable buckle structures, the two buckle structures are arranged at intervals, and the protruding directions of the two buckles are opposite, during the entering process into the internal space of the matching piece 21, the arrangement directions of the two buckles are the same as the extending direction of the matching hole 211, after entering the internal space of the matching piece 21, the arrangement directions of the two buckles intersect with the extending direction of the matching hole 211, thereby completing the clamping with the matching piece 21.

[0069] Specifically, the matching hole 211 is arranged on the top wall of the matching piece 21, facilitating the cooperation with the locking piece 132 moving along the height direction; the other side walls of the matching piece 21 are further provided with auxiliary holes 212, when the locking block 1321 cannot be rotated after entering the internal space of the matching piece 21, the locking block 1321 can be rotated through the auxiliary holes 212, thereby avoiding the complete locking condition.

[0070] Specifically, the connecting piece 14 is a combined structure of a trolley and a winding drum, and can also be an electric hoist, the above structures can all realize the movement of the lifting tool 13 on the trolley frame 11, can make the lifting tool 13 slide on the trolley frame 11 along the first direction X, and can make the lifting tool 13 move up and down along the height direction to position and fix with the material cage 20.

[0071] As Figure 7 and Figure 8As shown, the hoisting system of the embodiment of the present application, wherein the locking member 132 further has a connecting rod 1322 and a first guide block 1323, the connecting rod 1322 extends along the height direction of the frame 11, the first guide block 1323 is arranged at the end of the connecting rod 1322 away from the support plate 131, the locking block 1321 is arranged at the side of the first guide block 1323 close to the support plate 131, the first guide block 1323 is in a conical structure extending along the height direction, and the inclined surface of the first guide block 1323 is matched with each edge of the matching hole 211.

[0072] In the implementation, the first guide block 1323 is arranged at the end of the connecting rod 1322 away from the support plate 131, the locking block 1321 is arranged between the first guide block 1323 and the support plate 131 and connected to the connecting rod 1322. When it is needed to extend the locking block 1321 from the matching hole 211 into the inside of the matching member 21, the first guide block 1323 needs to be aligned with the matching hole 211, each inclined surface of the conical first guide block 1323 can be matched with each edge of the matching hole 211, in the process of entering the matching hole 211 along the height direction, each inclined surface of the first guide block 1323 slides along the edge of the matching hole 211, so that the first guide block 1323 can slide towards the center of the matching hole 211, thereby realizing the guidance of the locking member 132, so that the locking block 1321 of the locking member 132 can be aligned with the matching hole 211, and the locking block 1321 will not interfere with the side wall of the matching member 21 in the process of moving along the height direction, thereby ensuring the fixing efficiency between the locking member 132 and the matching member 21.

[0073] Specifically, the locking block 1321 is rotatably installed on the outer peripheral surface of the connecting rod 1322, in the process of penetrating the matching hole 211, the locking block 1321 is rotated to the same direction as the length direction of the first guide block 1323, and after the locking block 1321 enters the inside of the matching member 21, the locking block 1321 is rotated to the direction intersecting with the length direction of the first guide block 1323.

[0074] As Figure 2 and Figures 10 to 12As shown, the hoisting system of the embodiment of the present application, wherein the hoisting mechanism 12 further comprises a plurality of guide pieces 133 arranged on the support plate 131 and extending along the height direction of the vehicle frame 11, and each of the guide pieces 133 is provided with a second guide block 134 at the end away from the support plate 131, the second guide block 134 has a first guide surface 1341 and a second guide surface 1342 arranged adjacently, and the first guide surface 1341 and the second guide surface 1342 are arranged at an inclined angle with the height direction; the material cage 20 further has a plurality of positioning pieces 22, the plurality of positioning pieces 22 are arranged in one-to-one correspondence with the plurality of guide pieces 133, the first guide surface 1341 of each second guide block 134 can slide against the corresponding positioning piece 22, and the second guide surface 1342 of each second guide block 134 can slide against the outside of the material cage 20.

[0075] In specific implementation, when the hoisting mechanism 12 and the material cage 20 are positioned, positioning can be performed between the plurality of guide pieces 133 and the plurality of positioning pieces 22 of the material cage 20, when the plurality of guide pieces 133 and the plurality of positioning pieces 22 abut in one-to-one correspondence, accurate positioning between the hoisting mechanism 12 and the material cage 20 is completed, and the locking piece 132 of the hoisting mechanism 12 can lock the material cage 20, thereby realizing hoisting of the material cage 20 by the hoisting mechanism 12.

[0076] In each guide piece 133, the guide piece 133 is provided with the second guide block 134 at the end, the first guide surface 1341 and the second guide surface 1342 of the second guide block 134 are arranged at an inclined angle with the height direction, and the first guide surface 1341 and the second guide surface 1342 are arranged adjacently and extend in different directions. In the positioning process, the first guide surface 1341 of the second guide block 134 needs to abut against the corresponding positioning piece 22, and at the same time, the second guide surface 1342 needs to abut against the outside of the material cage 20, if the second guide block 134 is not completely aligned with the corresponding positioning piece 22, the inclined first guide surface 1341 and the second guide surface 1342 can slide between the positioning piece 22 and the outside of the material cage 20, thereby guiding the hoisting mechanism 12 to the position accurately matched with the material cage 20, thereby completing the overall guiding and positioning.

[0077] Specifically, the second guide block 134 is composed of two inclined wall structures, and the first guide surface 1341 and the second guide surface 1342 are arranged on the surfaces of the two wall structures, respectively.

[0078] Alternatively, the second guide block 134 can be a conical structure extending along the height direction, and the conical structure has the first guide surface 1341 and the second guide surface 1342 arranged towards the positioning piece 22 and the material cage 20.

[0079] As Figure 6As shown, in the embodiment of the present application, the hoisting mechanism 12 has four guide pieces 133 arranged in a rectangular shape, respectively as the four vertices of the rectangle, which can guide the hoisting mechanism 12 towards the center of the cage 20, further improving the positioning accuracy of the hoisting mechanism 12 and the cage 20; the hoisting mechanism 12 also has four locking pieces 132 arranged in a rectangular shape, respectively as the four vertices of the rectangle, and the rectangular area formed by the four locking pieces 132 is larger than the rectangular area formed by the four guide pieces 133. It should be noted that the number and arrangement position of the guide pieces 133 and the locking pieces 132 are not limited to the above, and can be arranged according to actual needs.

[0080] As shown in the embodiment of the present application, the hoisting system, wherein each guide piece 133 further includes a guide connecting part 135 connected to the second guide block 134, the side surface of the guide connecting part 135 extends along the height direction and is provided with a sliding plate 1351, the friction force of the surface of the sliding plate 1351 is smaller than the friction force of the first guide surface 1341 and the second guide surface 1342, and the sliding plate 1351 is used for abutting cooperation with the positioning piece 22 and the cage 20. Figure 10

[0081] Specifically, when the guide piece 133 moves along the height direction to abut the guide connecting part 135 with the positioning piece 22 and the cage 20, the sliding plate 1351 with small surface friction of the guide connecting part 135 can generate small resistance between the positioning piece 22 and the cage 20, avoiding affecting the locking action between the locking piece 132 and the cooperating piece 21 of the cage 20, further improving the locking efficiency between the hoisting mechanism 12 and the cage 20, and further improving the overall work efficiency.
