[0076] As mentioned in the background technology section, each photovoltaic string uses an inverter, which is installed on a bracket next to the photovoltaic string, and then enters the AC power grid after convergence. The number of photovoltaic modules in each photovoltaic string is different, and the specifications and sizes of the inverters used are also different. Photovoltaic string inverters are usually rectangular box structures, and the lifting tools used usually include manual hoists, hanging baskets, etc. On the one hand, it is not convenient to fix the inverter on these lifting tools, and it is not convenient to quickly separate the inverter from the lifting tools after the installation is completed. On the other hand, it cannot be flexibly adjusted as the size of the inverter changes, and its versatility is poor. In addition, due to the uneven distribution of the electrical components inside the inverter, the weight of each part of the box is unbalanced. It is not easy to align the mounting holes on the box with the mounting holes on the bracket during lifting, which makes it inconvenient to tighten and affects the installation efficiency.

[0077] In view of the above problems existing in the prior art, the utility model provides a lifting tool. The lifting tool provided by the utility model includes a support assembly 100, a lifting assembly 200 and a supporting mechanism 300, and the lifting assembly 200 is arranged on the support assembly 100. Among them, the supporting mechanism 300 includes a supporting seat 310, two connecting assemblies 320 and two supporting members 330, and the supporting seat 310 is connected to the lifting assembly 200 by setting the supporting seat 310 to lift and lower. By arranging a plurality of first connection parts 311 at intervals along the first direction and the second direction on the lower surface of the supporting seat 310, a second connection part 321 matching the first connection part 311 is arranged at one end of the connecting assembly 320, and two second connection parts 321 are correspondingly connected to two of the first connection parts 311, so as to select a suitable supporting position according to the length or width of the inverter body 10, and two supporting members 330 are correspondingly connected to the other ends of the two connecting assemblies 320, and a supporting cavity 301 is formed between the supporting seat 310, and the inverter body 10 is placed in the supporting cavity 301. The supporting mechanism 300 is driven to move by the lifting assembly 200 to lift the inverter body 10 to a predetermined position on the bracket 20. That is, according to the length or width of the inverter body 10, the two connecting assemblies 320 are moved along the first direction or the second direction to select the connection part, so as to support the appropriate position on the inverter body 10, which can adapt to the lifting of photovoltaic string inverters of different sizes, and has a wider range of applications and stronger versatility.

[0078] The following specific embodiments are combined with the accompanying drawings to describe the technical solution of the utility model in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0079] Reference Figures 1 to 5 As shown, the lifting tool provided in this embodiment is used to lift the inverter body 10 onto the bracket 20 . The lifting tool includes a support assembly 100 , a lifting assembly 200 and a supporting mechanism 300 . The lifting assembly 200 is arranged on the support assembly 100 .

[0080] The supporting mechanism 300 includes a supporting seat 310 , two connecting components 320 and two supporting members 330 . The supporting seat 310 is connected to the lifting component 200 .

[0081] A plurality of first connection parts 311 are arranged at intervals along the first direction and the second direction on the lower surface of the supporting seat 310 . A second connection part 321 matching the first connection part 311 is arranged at one end of the connecting component 320 .

[0082] The two supporting members 330 are connected to the other ends of the two connecting components 320 , and form a supporting cavity 301 with the supporting seat 310 . The supporting cavity 301 is used to place the inverter body 10 .

[0083] The lifting assembly 200 is configured to drive the supporting mechanism 300 to move so as to lift the inverter body 10 to a predetermined position on the bracket 20 .

[0084] In this embodiment, the inverter body 10 is a roughly elongated box structure, and has a first mounting portion, such as a plurality of first mounting holes, on its back. The bracket 20 is used to fix the inverter body 10, and can be composed of two vertical poles and a plurality of cross bars, the two vertical poles are arranged side by side, and the two ends of the plurality of cross bars are respectively connected to the two vertical poles, and the cross bars have a second mounting portion matching the first mounting portion, such as a plurality of second mounting holes matching the first mounting holes, wherein the first mounting holes and the second mounting holes are connected by fasteners, such as bolt and nut assemblies.

[0085] The support assembly 100 is used to provide an installation base for the lifting assembly 200 and the supporting mechanism 300. It can be a rod-shaped, frame-shaped structure, etc., which can play a supporting role and is easy to use. The lifting assembly 200 is used to drive the supporting mechanism 300 to move up and down. It can be a manual or electric hoist, a pull rope and reel assembly, a gear and rack mechanism, etc., which can drive the supporting mechanism 300 to move up and down. It should be noted that in order to prevent the lifting assembly 200 from falling freely and falling to the ground during the lifting process, the lifting assembly 200 needs to have a self-locking function or a self-locking mechanism.

[0086] The support seat 310 is used to provide a mounting base for the connecting assembly 320 and the supporting member 330. It can be a plate-shaped, frame-shaped structure, such as a rectangular supporting plate. The support seat 310 can be directly connected to the lifting assembly 200, or indirectly connected to the lifting assembly 200 through other mechanisms or components. The lower surface of the support seat 310 is provided with a plurality of first connecting portions 311 along the first direction and the second direction, respectively. Figure 1 The X-axis direction is distributed along Figure 4 The first connecting parts 311 are arranged in a rectangular array on the lower surface of the support seat 310 in the middle Z-axis direction. It should be noted that the first direction and the second direction are perpendicular to each other so as to be adjusted according to the length and width of the inverter body 10.

[0087] The connecting component 320 is used to connect the supporting member 330 and the supporting seat 310 to form a supporting cavity 301 capable of placing the inverter body 10. It can be a rod-shaped, strip-shaped structure, and there are two of them, or more. The upper end of the connecting component 320 has a second connecting portion 321, and the second connecting portion 321 matches the first connecting portion 311. The first connecting portion 311 at a suitable position is selected according to the length and width of the inverter body 10 to be hoisted. The second connecting portions 321 on the two connecting components 320 are correspondingly connected to the two first connecting portions 311 at suitable positions. Among them, the first connecting portion 311 and the second connecting portion 321 can be detachably connected by means of screw connection, snap connection, plug connection, etc., to ensure that the connection is stable and detachable.

[0088] The supporting member 330 is used to support the bottom of the inverter body 10, and it can be a plate-shaped, strip-shaped, tubular or other structure. The two supporting members 330 can be connected to the other end of the two connecting components 320 away from the supporting seat 310 by plugging, screwing, snapping, etc., and the supporting member 330 is connected to the connecting component 320 and the supporting seat 310 to form a supporting cavity 301 with an opening on one side, and the supporting cavity 301 is used to place the inverter body 10.

[0089] Specifically, combined Figure 1 , Figure 4 , Figure 5 As shown, the lifting tool is placed next to the bracket 20. On the one hand, for a photovoltaic string inverter with a larger outer size, first connect the two connecting components 320 as shown in FIG. Figure 1 Move in the opposite direction of the X axis and along Figure 4 The positive and negative directions of the middle Z axis are relatively far apart to select the appropriate first connection part 311, and each second connection part 321 is connected to each first connection part 311 accordingly to accommodate the placement of a longer and wider inverter body 10. On the other hand, for a photovoltaic string inverter with a smaller size, first connect the two connection components 320 as shown in FIG. Figure 1 Move in the positive direction of the X axis, and respectively along Figure 4 The positive and negative directions of the middle Z axis are relatively close to each other to select a suitable first connection part 311, and each second connection part 321 is correspondingly connected to each first connection part 311 to accommodate the placement of a shorter and thinner inverter body 10. Finally, the lifting assembly 200 drives the supporting mechanism 300 to move, so as to lift the inverter body 10 to a predetermined position on the bracket 20, and the first mounting part and the second mounting part are fixed by fasteners, and the lifting tool is moved.

[0090] It should be noted that when hoisting to the predetermined position, Figure 5As shown, the first mounting part and the second mounting part are roughly in the same horizontal direction, but have a certain distance between them. At this time, the lifting tool together with the inverter body 10 can be moved closer to the bracket 20 to make the first mounting part contact with the second mounting part. A plurality of rollers (not shown in the figure) can also be set at the bottom of the support assembly 100 to facilitate movement.

[0091] Compared with the hoisting tool with a single determined hoisting position, the hoisting tool provided in this embodiment can move the two connecting components 320 along the first direction or the second direction to select the connection position according to the length or width of the inverter body 10, so as to support the appropriate position on the inverter body 10, and can adapt to the hoisting of photovoltaic string inverters of different sizes, with a wider range of applications and stronger versatility. Moreover, by adjusting the appropriate connection position, the center of gravity of the inverter body 10 and the supporting mechanism 300 is roughly in the same vertical direction as the lifting point of the lifting component 200, ensuring that the inverter body 10 is basically not skewed during the hoisting process, which facilitates the alignment and connection of the first mounting part and the second mounting part.

[0092] It can be understood that the lifting tool provided by the utility model includes a support assembly 100, a lifting assembly 200 and a supporting mechanism 300, and the lifting assembly 200 is arranged on the support assembly 100. Among them, the supporting mechanism 300 includes a supporting seat 310, two connecting assemblies 320 and two supporting members 330, and the supporting seat 310 is connected to the lifting assembly 200 by setting the supporting seat 310 to lift the supporting seat 310. By arranging a plurality of first connecting parts 311 at intervals along the first direction and the second direction on the lower surface of the supporting seat 310, a second connecting part 321 matching the first connecting part 311 is arranged at one end of the connecting assembly 320, and the two second connecting parts 321 are correspondingly connected to two of the first connecting parts 311, so as to select a suitable supporting position according to the length or width of the inverter body 10. The two supporting members 330 are correspondingly connected to the other ends of the two connecting assemblies 320, and a supporting cavity 301 is formed between the supporting seat 310, and the inverter body 10 is placed using the supporting cavity 301. The lifting assembly 200 drives the supporting mechanism 300 to move, so as to lift the inverter body 10 to a predetermined position on the bracket 20. That is, the two connecting assemblies 320 are moved in the first direction or the second direction to select the connecting position according to the length or width of the inverter body 10, so as to support the appropriate position on the inverter body 10, which can adapt to the lifting of photovoltaic string inverters of different sizes, has a wider application range and stronger versatility.

[0093] In a possible design, the connection assembly 320 includes a first connection member 3201, a second connection member 3202 and a first driving member 3203, and the second connection portion 321 is located at one end of the first connection member 3201. The other end of the first connection member 3201 is connected to one end of the second connection member 3202 through the first driving member 3203, and the other end of the second connection member 3202 is connected to the supporting member 330. The first driving member 3203 is configured to drive the first connection member 3201 and the second connection member 3202 to move relatively closer or farther, so as to adjust the distance between the supporting member 330 and the supporting seat 310.

[0094] For example, in combination Figure 1 , Figure 4 As shown, the first connecting member 3201 can be a first screw, the upper end of the first screw has a second connecting portion 321, the second connecting member 3202 can be a second screw, the lower end of the second screw is connected to the supporting member 330, the first screw and the second screw have opposite thread rotation directions, and the first driving member 3203 can be a screw sleeve that matches the first screw and the second screw respectively, and the lower end of the first screw and the upper end of the second screw are connected by the screw sleeve respectively. In this way, when the screw sleeve is rotated, the first screw and the second screw can be moved closer or farther relative to each other, so as to adjust the distance between the supporting member 330 and the supporting seat 310 according to the height of the inverter body 10, and the application range is wider. At the same time, during the hoisting process, the upper surface of the inverter body 10 is pressed against the lower surface of the supporting seat 310, which can also prevent the inverter body 10 from tipping over from the supporting member 330 to a certain extent, thereby ensuring safety.

[0095] Of course, the connecting component 320 can also be replaced by other mechanisms or components with telescopic adjustment functions, such as a telescopic mechanism consisting of two racks and a gear, etc. The specific type of the connecting component 320 can be determined according to actual needs and is not specifically limited in this embodiment.

[0096] In order to make the supporting member 330 adapt to the adjustable width of the inverter body 10, in this embodiment, one side of the supporting member 330 has a first plug-in portion 331, and the side of the connecting component 320 away from the second connecting portion 321 has a second plug-in portion 322 that matches the first plug-in portion 331. The first plug-in portion 331 is plugged with the second plug-in portion 322, and moves relatively to adjust the length of the supporting member 330 extending into the supporting cavity 301.

[0097] For example, in combination Figure 1 , Figure 4As shown, the first plug-in portion 331 may be a plug-in rod, and the second plug-in portion 322 may be a socket matching the plug-in rod. The plug-in rod is inserted into the socket and can move laterally to adjust the length of the supporting member 330 extending into the supporting cavity 301. This can adapt to the hoisting of thicker or thinner inverter bodies 10, and sometimes can also prevent the supporting member 330 from extending too long into the supporting cavity 301 and interfering with the bracket 20.

[0098] Of course, the first plug-in portion 331 and the second plug-in portion 322 can also be replaced by other plug-in structures, as long as the supporting member 330 is adjustable in the lateral movement. It should be noted that in order to prevent the first plug-in portion 331 and the second plug-in portion 322 from freely moving, a locking member, such as a locking screw, can be provided between the first plug-in portion 331 and the second plug-in portion 322 to limit the free movement of the two. The specific types of the first plug-in portion 331 and the second plug-in portion 322 can be determined according to actual needs and are not specifically limited in this embodiment.

[0099] Furthermore, in this embodiment, a stopper 332 is provided on one side of the supporting cavity 301 of the supporting member 330, and the stopper 332 is used to abut against the side wall of the inverter body 10 to limit the position. Figure 1 As shown, the stopper 332 may be a stopper, a baffle, a protrusion, etc., which is located on the supporting member 330 on one side of the supporting cavity 301 and away from the connecting assembly 320 .

[0100] In this way, when the inverter body 10 is placed in the supporting cavity 301, the bottom of the inverter body 10 is placed on the supporting member 330, the front side wall of the inverter body 10 is pressed against the connecting assembly 320, and the lower side wall of the back side of the inverter body 10 is pressed against the stopper 332, thereby preventing the inverter body 10 from sliding off the supporting member 330. The specific type of the stopper 332 can be determined according to actual needs and is not specifically limited in this embodiment.

[0101] In order to fine-tune the height of the circumference of the inverter body 10, in this embodiment, a plurality of adjustment mechanisms 400 are further included. The adjustment mechanisms 400 include a base 410, a drive assembly 420, and a first traction member 430. Each base 410 is connected to the support seat 310 at intervals, and each drive assembly 420 is correspondingly arranged on each base 410. One end of each first traction member 430 is commonly connected to the lifting assembly 200, and the other end of each first traction member 430 is correspondingly connected to each drive assembly 420. Each drive assembly 420 is configured to move relative to each first traction member 430 when the inverter body 10 is in a predetermined position to adjust the height of the circumference of the inverter body 10 respectively, so that the first mounting portion on the inverter body 10 is aligned with the second mounting portion of the bracket 20.

[0102] Specifically, if Figures 1 to 4 As shown, the adjustment mechanism 400 is used to fine-tune the height of the supporting mechanism 300 together with the circumference of the inverter body 10, and two of them are provided. Among them, the base 410 is used to provide an installation basis for the driving assembly 420 and the first traction member 430, which can be a shell-shaped, frame-shaped structure, etc. The base 410 can be connected to the upper surface of the supporting seat 310 by screwing, welding, clamping, etc., and multiple bases 410 are arranged around the circumference of the supporting seat 310.

[0103] The driving component 420 and the first traction member 430 are correspondingly installed on the base 410, wherein the first traction member 430 can be a traction rope, a traction belt, a traction chain, etc., one end of each first traction member 430 is commonly connected to the lifting point of the lifting component 200, and the other end of each first traction member 430 is correspondingly connected to each driving component 420. The driving component 420 is used to move relative to the first traction member 430 or to retract the first traction member 430. It can be a winding drum, a winding mechanism, etc. The above-mentioned traction rope or traction belt or traction chain is wound on the winding drum or the winding mechanism, and the extension length of the first traction member 430 relative to the base 410 can be adjusted by rotating and retracting the winding drum or the winding mechanism.

[0104] More specifically, when the inverter body 10 is in a predetermined position, each driving assembly 420 is moved relative to each first traction member 430 to adjust the height of the circumference of the inverter body 10, so that the first mounting portion on the inverter body 10 is aligned with the second mounting portion of the bracket 20, that is, each first mounting hole can be aligned with each second mounting hole, thereby avoiding the situation where the first mounting portion cannot be aligned with the second mounting portion due to the inverter body 10 being skewed during the lifting process.

[0105] Furthermore, in the present embodiment, three adjusting mechanisms 400 are provided, wherein the connection points between the first traction member 430 and the driving assembly 420 on two of the adjusting mechanisms 400 are relatively arranged on the first side of the supporting seat 310, and both are away from the connecting assembly 320, and the connection point between the first traction member 430 and the driving assembly 420 on the other adjusting mechanism 400 is arranged on the second side of the supporting seat 310, and the second side is on the same side as the connecting assembly 320 (both relative to the first side).

[0106] Specifically, combined Figure 1 , Figure 3 As shown, in this way, by adjusting the two adjustment mechanisms 400 away from the connecting assembly 320, the height of both sides of the inverter body 10 in the length direction can be fine-tuned, and by adjusting the other adjustment mechanism 400, the inclination angle of the back of the inverter body 10 relative to the horizontal plane can be fine-tuned to ensure that the back of the inverter body 10 can better fit with the bracket 20 up and down.

[0107] Of course, the adjustment mechanisms 400 may be provided in greater numbers and arranged at intervals on the circumferential side of the supporting seat 310 . This may be determined according to actual needs and is not specifically limited in this embodiment.

[0108] Further, in this embodiment, the driving assembly 420 includes a reel 421, a worm gear 422 and a worm 423 rotatably disposed on the base 410, and the first traction member 430 is wound around the reel 421. The worm gear 422 is in driving connection with the reel 421, and the worm 423 is in driving connection with the worm gear 422. The worm 423 is configured to drive the worm gear 422 and the reel 421 to rotate so as to retract and release the first traction member 430.

[0109] Specifically, if Figure 2 As shown, the first traction member 430 is wound on the winding wheel 421, and the winding wheel 421 and the worm wheel 422 are coaxially connected through a rotating shaft. The two ends of the rotating shaft can be rotatably installed on the base 410 through bearing assemblies, and the rotating axis is arranged horizontally. The two ends of the worm 423 can also be rotatably installed on the base 410 through the shaft head. The worm 423 is matched and connected with the worm wheel 422, and the rotating axis of the worm 423 is perpendicular to the rotating axis of the worm wheel 422.

[0110] Thus, by rotating the worm 423, the worm wheel 422 and the retracting wheel 421 can be driven to rotate together, thereby realizing the retraction and release of the first traction member 430. Moreover, the worm 423 and the worm wheel 422 have a self-locking function, thereby preventing the retracting wheel 421 from rotating freely.

[0111] Of course, the driving assembly 420 can also be replaced by other types of mechanisms that can adjust the length of the first traction member 430 between the base 410 and the lifting assembly 200. In addition, the specific models of the winding wheel 421, the worm wheel 422 and the worm 423 can be determined according to actual needs and are not specifically limited in this embodiment.

[0112] Furthermore, in this embodiment, a manipulation portion 4231 is disposed at one end of the worm 423, and the manipulation portions 4231 on each worm 423 are located on the same side and away from the connection assembly 320. Figure 3 As shown, the operating part 4231 is used to drive the worm 423 to rotate, which can be a joystick with a hand-cranked part. One end of the joystick is connected to the end of the worm 423 by screwing, plugging, stopping, etc., and the other end of the joystick on each worm 423 extends toward the side away from the connecting component 320.

[0113] In this way, it is convenient for the operator to stand on the side close to the back of the inverter body 10 to adjust each adjustment mechanism 400 respectively, without having to go to each adjustment mechanism 400 to adjust it, which is more conducive to adjusting while observing and more humane.

[0114] Of course, the operating part 4231 may also be replaced by other types of operating components to facilitate the operation of driving the worm 423 to rotate. The specific type of the operating part 4231 can be determined according to actual needs and is not specifically limited in this embodiment.

[0115] Optionally, in this embodiment, the support assembly 100 includes a support base 110, a first support member 120, a second support member 130 and a locking member 140, wherein the first support member 120 is connected to the support base 110. The second support member 130 includes a support section 131 and a cantilever section 132 connected to the support section 131, wherein the support section 131 is arranged on the first support member 120 for vertical movement, and the lifting assembly 200 is connected to the supporting mechanism 300 via the cantilever section 132. The locking member 140 is connected between the support section 131 and the first support member 120, and is used to limit the relative movement of the two.

[0116] Specifically, Figure 1 As shown, the support base 110 can be a block-shaped, shell-shaped structure, etc., and the support base 110 can also have legs extending in all directions to increase the support surface. The first support member 120 is used for support, which can be a rod-shaped, strip-shaped structure, etc. The first support member 120 is vertically arranged on the support base 110, and the upper end of the first support member 120 has a plug sleeve.

[0117] The second support member 130 includes a connected support section 131 and a cantilever section 132, which are roughly in the shape of a "7". The lower end of the support section 131 has a plug-in rod that matches the plug-in sleeve. The plug-in rod is inserted into the plug-in sleeve and can move relatively in the vertical direction to adjust the height of the cantilever section 132. The locking member 140 can be a pin, which is connected to the plug-in sleeve. A plurality of sockets matching the pins are arranged at intervals in the vertical direction on the plug-in rod, and the pin is plugged into one of the sockets.

[0118] Of course, the plug-in structure between the first support member 120 and the support section 131 can also be replaced by other movable structures, as long as the two can move vertically to adjust the height. In addition, the locking member 140 can also be replaced by other types of locking components, as long as the first support member 120 and the support section 131 can be quickly locked or unlocked, which is not specifically limited in this embodiment.

[0119] Further, in this embodiment, the lifting assembly 200 includes a second traction member 210 and a second driving member 220, and an upper fulcrum 101 is provided on the cantilever section 132. One end of the second traction member 210 is connected to the supporting mechanism 300, and the other end of the second traction member 210 is connected to the second driving member 220 after bypassing the upper fulcrum 101. The second driving member 220 is configured to drive the second traction member 210 to move so that the supporting mechanism 300 is lifted or lowered relative to the upper fulcrum 101.

[0120] For example, Figure 1 As shown, one or more upper fulcrums 101 are provided on the cantilever section 132, and a pulley may be provided at the upper fulcrum 101. The second traction member 210 may be a traction rope, a traction belt, a traction chain, etc., and the second driving member 220 may be a manual hoist, a winding wheel, etc. One end of the second traction member 210 is connected to the supporting mechanism 300, and the other end of the second traction member 210 is connected to the second driving member 220 after passing through the upper fulcrum 101.

[0121] In this way, the second driving member 220 can drive the second traction member 210 to move, that is, retract and release the second traction member 210, so that the supporting mechanism 300 can be raised or lowered relative to the upper fulcrum 101. It should be noted that the second driving member 220 needs to have a self-locking function to prevent the supporting mechanism 300 from falling to the ground when the second driving member 220 is released.

[0122] Of course, the lifting assembly 200 may also be replaced by other components or mechanisms with lifting functions, as long as they can realize the lifting of the supporting mechanism 300. This embodiment does not impose too many restrictions on this.
