[0047] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0048] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] Reference Figures 1 to 7 As shown, this embodiment provides a photovoltaic panel lifting device for photovoltaic power station construction, including a lifting box 2 and a guide vehicle 3. The lifting box 2 is connected to the hook 4 of the crane through a hanging ring 24 hinged thereto, and the hanging ring 24 is rotatably set on the top of the lifting box 2. The guide vehicle 3 is slidably set on a plurality of purlins 1. After the lifting box 2 is filled with photovoltaic panels 6, it is lifted by the crane and seated on the guide vehicle 3, so as to facilitate the subsequent uniform laying of the photovoltaic panels 6 on the bracket.

[0050] A main box 21 and a cargo box 22 with an opening at the bottom are arranged in the hanging box 2. The main box 21 is connected to the guide vehicle 3. The cargo box 22 extends out of the guide vehicle 3 and is located above a plurality of purlins 1. Then, the photovoltaic panels 6 in the cargo box 22 can be accurately dropped onto the plurality of purlins 1 after being discharged from the opening at the bottom of the cargo box 22. Usually, two purlins 1 are arranged to fix the upper and lower ends of the photovoltaic panels 6.

[0051] More specifically, Figure 1-Figure 3 As shown, two storage conveyor belts 5 are symmetrically arranged in the cargo box 22, and the storage conveyor belt 5 includes a plurality of rollers 51 arranged at vertical intervals, and a chain belt 52 wound around the plurality of rollers 51, and a plurality of rubber strips 53 are arranged at intervals on the chain belt 52, and a U-shaped groove 54 is formed between adjacent rubber strips 53; a plurality of photovoltaic panels 6 are stored between the two storage conveyor belts 5, and the two ends of the photovoltaic panel 6 are respectively placed in two U-shaped grooves 54 on the same plane of the two storage conveyor belts 5; and a driving assembly 7 is also included, and the driving assembly 7 is used to drive the storage conveyor belt 5 to rotate. The storage conveyor belt 5 is driven to rotate by the driving component 7. When the two U-shaped grooves 54 at the same position rotate to be out of alignment with each other, that is, after rotating to the roller 51 at the lower end, the two U-shaped grooves 54 are separated from the two ends of the photovoltaic panel 6 at the same time, and then the photovoltaic panel 6 falls out of the cargo box 22 and falls on multiple purlins 1. Then the guide vehicle 3 moves the hanging box 2 to a lower position on the purlin 1, and the workers fix the photovoltaic panel 6 that has just fallen into place to the purlin 1 by screws, etc., and in this way, multiple photovoltaic panels 6 can be laid on the same row of brackets. The hanging box 2 maintains a relatively fixed position with the purlin 1 through the guide vehicle 3, and then when the photovoltaic panel 6 falls, it can be quickly aligned with the purlin 1, which is convenient for workers to fix, greatly improving the installation efficiency of the photovoltaic panel 6, and it can be completed without using too much manpower and material resources.

[0052] like Figure 1-Figure 7 As shown, the guide vehicle 3 includes a frame 31 and a guide wheel group 32. A plurality of guide wheel groups 32 are arranged at the bottom of the frame 31, and the main box 21 is arranged on the frame 31. Usually, two guide wheel groups 32 are arranged, and the positions of the guide wheel groups 32 are determined according to the number of purlins 1. When there are multiple purlins 1, the two guide wheel groups 32 are respectively arranged on the two purlins 1 located on the outside.

[0053] More specifically, as shown in FIG7 , the guide wheel group 32 includes a plurality of main pulleys 321 and a plurality of secondary pulleys 322. The main pulleys 321 are arranged on the frame 31 at intervals and are located at the bottom of the frame 31. The plurality of main pulleys 321 on the same purlin 1 are all in rolling contact with the top of the purlin 1 to support the frame 31 and the hanging box 2.

[0054] The bottom of the frame 31 is also provided with a side plate 33, and a plurality of secondary pulleys 322 are arranged at intervals at the lower end of the side plate 33 along the traveling direction, and the secondary pulleys 322 are in rolling contact with the bottom of the purlin 1. The secondary pulleys 322 are mainly used to prevent the frame 31 from being separated from the purlin 1, especially when a plurality of purlins 1 with height differences are arranged on the inclined bracket, and the two guide wheel groups 32 are not in the same horizontal plane so that the entire frame 31 and the hanging box 2 are inclined at a certain angle, the secondary pulleys 322 can be used to hook the purlin 1 to prevent the frame 31 from being separated from the purlin 1.

[0055] More specifically, Figure 4-Figure 7 As shown, the guide wheel group 32 also includes a plurality of adjusting screws 323 that are arranged through the side plates 33. The adjusting screws 323 are threadedly matched with the side plates 33. A universal ball 324 is arranged at the end of the adjusting screw 323. The universal ball 324 rolls against the outer wall of the purlin 1. The position of the universal ball 324 can be adjusted by rotating the adjusting screw 323, so that the universal ball 324 rolls against the outer side wall of the purlin 1. It is mainly used to keep the relative position of the frame 31 and the purlin 1 fixed when the frame 31 and the hanging box 2 are tilted, thereby preventing the frame 31 from sliding along the inclined surface.

[0056] The lower end of the side plate 33 is hinged with a sub-plate 34, and the sub-pulley 322 is arranged on the sub-plate 34; a plurality of first locking holes 341 are arranged at intervals on the outer side of the side plate 33, and a plurality of second locking holes 342 are arranged at intervals on the outer side of the sub-plate 34, and the plurality of second locking holes 342 correspond to the plurality of first locking holes 341 one by one; it also includes a locking handle 343, and a plurality of locking pins 344 are arranged at intervals on the locking handle 343. After the plurality of locking pins 344 are simultaneously inserted into the plurality of first locking holes 341 and the second locking holes 342, the sub-pulley 322 rolls and abuts against the bottom of the purlin 1.

[0057] When implementing it, Figure 4-Figure 7As shown, when the vehicle frame 31 is set on the purlin 1, the main pulley 321 is first rolled and placed on the corresponding purlin 1, and the adjusting screw 323 is rotated to make the universal ball 324 roll and abut against the side wall of the purlin 1, so that the main pulley 321 is further aligned with the purlin 1, and then the auxiliary plate 34 is rotated to make the auxiliary plate parallel to the side plate 33, so that the first locking holes 341 are respectively aligned with the second locking holes 342. Usually, when the auxiliary pulley 322 rolls and abuts against the bottom of the purlin 1, the first locking holes 341 and the second locking holes 342 can be aligned, and finally the lock handle 34 is picked up. 3. By simultaneously inserting a plurality of locking pins 344 into the corresponding first locking holes 341 and second locking holes 342, the secondary pulley 322 can be always in rolling contact with the bottom of the purlin 1. At the same time, since the center of gravity of the secondary pulley 322 is not located below the hinge between the secondary plate 34 and the side plate 33, there is a moment that causes the second locking hole 342 to deviate from the first locking hole 341. As a result, the locking pins 344 can overcome their own gravity by relying only on the friction between the first locking hole 341 and the second locking hole 342 without the action of external force, and will not be separated from the first locking hole 341 and the second locking hole 342.

[0058] like Figure 4-Figure 7 As shown, the driving assembly 7 includes a worm wheel 71, a worm 711, a first bevel gear 712 and a second bevel gear 713. The rotating shaft of a roller 51 extends out of the main box 21 and is connected to the worm wheel 71; the rotating shaft is also rotatably connected to the main box 21;

[0059] The worm 711 is arranged on the frame 31 for approximately vertical rotation. The worm 711 can be set at a certain inclination. When the hanging box 2 is seated on the frame 31, the worm wheel 71 first rolls on the worm 711, thereby driving the storage conveyor belt 5 to rotate. After the storage conveyor belt 5 discharges the photovoltaic panel 6 at the bottom, the worm 711 is meshed with the worm wheel 71.

[0060] The lower end of the worm 711 passes through the frame 31 and is connected to the first bevel gear 712 ; the rotating shaft of a main pulley 321 extends out of the side plate 33 and is connected to the second bevel gear 713 , and the second bevel gear 713 is meshed with the first bevel gear 712 .

[0061] When implementing it, Figure 2-Figure 7 As shown, by driving the frame 31 to move on the purlin 1, the main pulley 321 also rotates, thereby driving the second bevel gear 713 to rotate, the second bevel gear 713 drives the first bevel gear 712 to rotate, the first bevel gear 712 synchronously drives the worm 711 to rotate, the worm 711 drives the storage conveyor belt 5 to rotate by driving the worm wheel 71 to rotate, when the frame 31 moves to the next predetermined position, the storage conveyor belt 5 also discharges the next photovoltaic panel 6, the speed ratio between the main pulley 321 and the storage conveyor belt 5 can be adjusted by changing the gear ratio of the worm wheel 71 and the worm 711, thereby adjusting the placement spacing of the photovoltaic panels 6, and the placement spacing can also be adjusted according to photovoltaic panels 6 of different widths.

[0062] A guide groove 72 is vertically arranged on the main box 21, a driving screw 721 is rotatably arranged in the guide groove 72, a slider 723 is slidably arranged in the guide groove 72, the slider 723 is threadedly matched with the driving screw 721, and a first guide wheel 724 is arranged on the slider 723; two second guide wheels 725 are symmetrically arranged on the main box 21, and the two second guide wheels 725 are located on both sides of the upper end of the guide groove 72; two third guide wheels 726 are symmetrically arranged on the main box 21, and the two third guide wheels 726 are located on both sides of the lower end of the guide groove 72;

[0063] The connector 73 is also provided with a cavity at one end thereof, a sleeve 731 is rotatably provided in the cavity, the sleeve 731 passes through the connector 73, and a fourth guide wheel 732 is sleeved on a portion of the sleeve 731 located in the cavity;

[0064] A transmission belt 727 is wound around the first guide wheel 724 , the second guide wheel 725 , the third guide wheel 726 and the fourth guide wheel 732 . The connector 73 is detachably connected to the guide vehicle 3 . In specific implementation, a special-shaped groove 74 is provided on the side plate 33 , and the connector 73 is engaged with the special-shaped groove 74 .

[0065] When implementing it, Figure 4-Figure 7 As shown, when the box 2 is initially lifted above the guide vehicle 3, it is difficult to align the box 2 with the guide vehicle 3, and the guide vehicle 3 is in an inclined state, so the box 2 needs to be adjusted to an inclined state to accurately sit on the guide vehicle 3. By rotating the driving screw 721, the slider 723 moves upward, and then the first guide wheel 724 moves upward. The transmission belt 727 between the first guide wheel 724 and the two second guide wheels 725 withdraws downward under the action of the gravity of the connector 73. Then, the connector 73 is lowered. After the connector 73 is lowered to the encounter position, the connector 73 is pushed horizontally and embedded into the special-shaped groove 74. There is a notch above the special-shaped groove 74 for the transmission belt 727 to move. A plurality of lock buckles 741 are rotatably arranged on the notch of the special-shaped groove 74. When the connector 73 is placed in the special-shaped groove 74, the lock buckle 741 is rotated to rotate into the special-shaped groove 74, and then abuts against the connector 73, thereby preventing the connector 73 from being separated from the special-shaped groove 74.

[0066] Then the driving screw 721 is driven to reverse, thereby driving the slider 723 to move downward, and the transmission belt 727 is pulled downward by the first guide wheel 724, so that the connecting head 73 is close to the hanging box 2, and the two sets of transmission belts 727 on both sides of the main box 21 cooperate to make the hanging box 2 initially tilted, and then the hanging box 2 continues to be lowered, and at the same time the transmission belt 727 is tightened for guidance, and finally the hanging box 2 is accurately seated on the guide vehicle 3. When the hanging box 2 is in place, the worm gear 71 moves into place on the worm 711, and at the same time, the first photovoltaic panel 6 below is discharged, and then the guide vehicle 3 is driven to move, and the photovoltaic panels 6 are evenly spaced onto the bracket, which not only can accurately and quickly place multiple photovoltaic panels 6 in place, but also saves a lot of manpower and improves the lifting efficiency.

[0067] More specifically, Figure 4-Figure 7 As shown, a balancing seat 23 is provided at one end of the main box 21 away from the cargo box 22, and a first reducer 75 and a second reducer 76 are provided on the balancing seat 23. The first reducer 75 is transmission-connected to the driving screw 721 through a first synchronous belt 751; the first reducer 75 and the second reducer 76 can balance a part of the eccentric moment of the cargo box 22 on the frame 31. Although there is a secondary pulley 322 to offset the eccentric moment, some weights can still be set on the balancing seat to reduce the eccentric moment of the cargo box 22 on the frame 31.

[0068] The second reducer 76 is connected to one of the second guide wheels 725 through the second synchronous belt 761; the shaft of a main pulley 321 extends out of the special-shaped groove 74 and is spline-connected with the sleeve 731, so that the fourth guide wheel 732 rotates synchronously with the main pulley 321; and the second reducer 76 can drive the transmission belt 727 to rotate, and the transmission belt 727 drives the fourth guide wheel 732 to rotate and then drives the sleeve 731 to rotate, and the sleeve 731 is connected to the shaft of a main pulley 321, thereby driving a main pulley 321 to rotate. There are two main pulleys 321 on both sides that rotate synchronously, thereby driving the guide vehicle 3 to move on the purlin 1, and at the same time, the storage conveyor belt 5 can be driven through the other main pulley 321 to evenly discharge the photovoltaic panels 6 to improve the installation efficiency of the photovoltaic panels 6.

[0069] like Figure 1As shown, multiple groups of hanging boxes 2 can be set for rotational use. After the photovoltaic panels 6 in the current hanging box 2 are discharged, the locking handle 343 is used to pull out several locking pins 344, and then the first reducer 75 is used to control the driving screw 721 to rotate, thereby driving the slider 723 to move up and release the transmission belt 727. The transmission belt 727 on the low side can be released slightly faster. After the hanging box 2 is horizontal at a certain height above the guide vehicle 3, the hanging box 2 is lowered, the stress of the connecting head 73 is canceled, the lock buckle 741 is opened, and the connecting head 73 is taken out from the special-shaped groove 74, so that the hanging box 2 can be separated from the guide vehicle 3. Subsequently, in the process of lifting the hanging box 2, the slider 723 is moved down and reset, and then the new hanging box 2 is placed on the guide vehicle 3 according to the above steps by the crane.
