It usually includes components such as boom, clamping arm, and frame, and can be adaptively adjusted according to photovoltaic panels of different sizes and thicknesses to ensure the safety and stability of photovoltaic panels during the hoisting process. For example, the prior art publication number is CN221759294U, and the patent disclosed is named: A photovoltaic panel hoisting equipment patent, which includes a main body module, the main body module includes a frame, a U-shaped frame movably installed on both sides of the frame, a vacuum suction cup symmetrically installed on the U-shaped frame, an electric telescopic rod symmetrically fixed on the frame and fixedly connected to the U-shaped frame at the end, a structural frame rotatably installed in the middle of the frame, a driving member installed on one side of the structural frame, a worm gear installed on one side of the frame and engaged with the driving member, a plurality of hooks symmetrically fixed on the top of the structural frame, and a vacuum pump installed on the structural frame. The frame is used to install other components to ensure the stability of each component. Grooves are opened on both sides of the frame, and the ends of the U-shaped frame are slidably embedded in the grooves, which facilitates the extension and retraction of the U-shaped frame and ensures the stability of the U-shaped frame during the extension and retraction process. The problem with the prior art is that when the photovoltaic panel needs to be placed on the main module, although the above patent can adsorb photovoltaic panels of different specifications, during installation, since the module is set as an integral whole and the photovoltaic panel is directly installed through the adsorption structure, this requires high installation accuracy. The four corners of the photovoltaic panel need to be installed on the photovoltaic panel mounting frame at the same time, which has high requirements on accuracy and relatively high fault tolerance, resulting in insufficient convenience during installation. Summary of the invention

[0003] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments.

The specific scheme is as follows: A hoisting device for photovoltaic assembly installation, comprising a mobile vehicle for movement, a base fixedly mounted on a rear box of the mobile vehicle, a suspension arm mounted above the base, the suspension arm being used to hoist the photovoltaic panel, and further comprising: A clamping plate, the clamping plate being connectable to the top of the boom via a suspension rope; A clamping block is slidably mounted on both ends of the clamping plate. Slide grooves are provided at both ends of the clamping plate. The clamping block is slidably connected to the slide grooves to clamp both ends of the photovoltaic panel. A negative pressure chamber, the negative pressure chamber is opened inside the clamping plate, the bottom of the negative pressure chamber is closed, and the negative pressure chamber is used to adsorb the photovoltaic panel on the clamping plate; The main body is installed below the top of the boom; A first steel rope is fixedly connected to both ends of the top of the main body, and the top of the first steel rope is connected to the upper end of the boom; A movable frame, movably mounted on both ends of the main body, and a second guide wheel is rotatably mounted on the end of the movable frame; There are four second steel ropes, which are respectively arranged at the two ends of the main body, and are fixedly connected to the bottom of the main body. The four second steel ropes pass through the upper part of the second guide wheel and extend to the four corners of the clamping plate. The position of the second guide wheel is moved up and down by the rotation of the movable frame, so that the second steel ropes drive the two ends of the clamping plate to move up and down.

[0005] Preferably, one end of the boom is rotatably connected to the base, the boom is divided into multiple sections, a hydraulic rod is arranged under a section of the boom close to the base, the top of the hydraulic rod is hinged to both ends of the boom, the bottom of the hydraulic rod is slidably connected to the upper part of the tail box of the mobile vehicle, the middle part of the clamping block has a groove limiting structure, and the inner side of the slide groove is provided with a limiting protrusion matching the groove limiting structure.

[0006] Preferably, the top of the negative pressure chamber passes through to the upper part of the clamping plate, and a filter plate is provided on the top of the negative pressure chamber, and a number of through holes are evenly provided on the filter plate. When the photovoltaic panel is placed on the upper surface of the clamping plate, the bottom surface of the photovoltaic panel is in close contact with the top surface of the clamping plate, thereby blocking the through holes on the filter plate at the top of the negative pressure chamber, thereby forming a closed space inside the negative pressure chamber. At this time, when negative pressure is formed in the negative pressure chamber, the photovoltaic panel can be adsorbed on the upper part of the clamping plate.

[0007] Preferably, it also includes: A negative pressure plate is installed inside the negative pressure cavity, and the edge of the negative pressure plate contacts the inner wall of the negative pressure cavity. When the negative pressure plate slides downward, negative pressure is formed on the upper part of the negative pressure cavity, thereby adsorbing the photovoltaic panel; A sliding column, fixedly connected to the lower part of the negative pressure plate, and a first spring is connected between the bottom of the sliding column and the bottom of the inner wall of the negative pressure chamber; A hanging block is fixedly connected to the bottom of the sliding column by a soft rope. The hanging block mainly plays the role of a counterweight. The hanging block cooperates with the energized first spring to form a downward force, pulling the sliding column and the negative pressure plate downward, so that negative pressure is quickly formed inside the negative pressure chamber; The suction cup is fixedly connected to the clamping plate.

[0008] Preferably, the outer wall of the clamping block is connected to a second spring, the other end of the second spring is fixedly connected to the inner wall of the slide groove, and the ends of the two clamping blocks close to each other are also connected to a pull rope, the pull rope passes through the inside of the clamping plate into the negative pressure chamber, and the end of the pull rope away from the clamping block is connected to the top of the negative pressure plate. When the negative pressure plate moves downward, the pull rope can be pulled to make the two clamping blocks approach each other, thereby clamping the two ends of the photovoltaic panel. Pulleys are provided at both ends of the clamping blocks, and the pulleys can contact the top surface of the clamping plate. When the clamping blocks slide, the pulleys can roll on the clamping plate.

[0009] Preferably, the side wall of the counterweight seat is provided with a shift block, which is slidably connected to the side wall of the counterweight seat, and one end of the shift block located inside the negative pressure chamber is provided with a slope, and an elastic member is connected between the shift block and the side wall of the counterweight seat. When the negative pressure plate slides upward, under the action of the slope, the shift block can be slid to the outside of the counterweight seat until the lower part of the negative pressure plate is resting on the upper part of the shift block. Under the action of the elastic member, the shift block automatically rebounds, thereby clamping the negative pressure plate in the upper part of the negative pressure chamber. When the photovoltaic panel is installed on the clamping plate, the shift block is pulled out from the outside of the shift block, so that one end of the shift block leaves the bottom of the negative pressure plate, thereby allowing the negative pressure plate to move downward.

[0010] Preferably, the four corners of the clamping plate are respectively provided with lifting ears, and the bottom ends of the four second steel ropes are respectively fixedly connected to the four lifting ears.

A cavity is provided in the middle part of the main body, and the cavity can adapt to the rotation of the gear. A rack is also provided in the cavity, and the rack is meshed with the gear. A third spring is also connected between the bottom of the rack and the bottom of the inner wall of the cavity, and a sliding rod is connected to the top of the rack, and the sliding rod is sealingly and slidably connected to the cavity. A first interface is opened at the top of the cavity, and the first interface is used to connect to an external hydraulic pipeline.

[0012] Preferably, it also includes: A sliding sleeve, fixedly connected to the top end of the boom; An adjusting column, mounted in the sliding sleeve; A sliding block is fixedly connected to the middle of the adjusting column, the sliding block is slidably mounted in the middle of the sliding sleeve, and both ends of the sliding sleeve also have sliding spaces; The second interface is provided at both ends of the sliding sleeve and is connected to an external hydraulic pipeline.

[0013] A method for installing a photovoltaic module comprises the following steps: S1. The mobile vehicle moves to the vicinity of the stacking position of the photovoltaic panels, and then controls the crane arm to move the clamping plate above the photovoltaic panels; S2, the two movable frames respectively drive the two second guide wheels to descend, unwind the second steel rope, and make the two ends of the clamping plate descend in sequence, and move the photovoltaic panel onto the clamping plate; S3, the negative pressure cavity on the clamping plate generates negative pressure, adsorbing the photovoltaic panel on the clamping plate, and the two clamping blocks clamp the two ends of the photovoltaic panel; S4, the crane moves the photovoltaic panel to the location where it is to be installed; S5. The movable frame then drives the two second guide wheels to descend respectively, unwinds the second steel rope, and allows the two ends of the clamping plate to descend in sequence. When one end of the clamping plate descends, the two corners of one end of the photovoltaic panel are placed on the mounting frame, and then the other end of the clamping plate descends, so that the other end of the photovoltaic panel is placed on the mounting frame, and then the energized first spring is de-energized. Under the upward restoring action of the first spring, the negative pressure of the negative pressure chamber loses its effectiveness, and then the photovoltaic panel is separated from the clamping plate to complete the installation.

[0014] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: 1. The present invention lowers both ends of the clamping plate at one time so that both ends of the photovoltaic panel are placed on the mounting frame of the photovoltaic panel respectively. First, two points at one end of the photovoltaic panel are placed on the mounting frame, and then the other end of the photovoltaic panel is placed on the mounting frame. Compared with the four-point direct installation method of the prior art, the two-point installation method of the present application has a lower fault tolerance rate.

[0015] 2. The downward pressure is formed by the cooperation between the hanging block and the energized first spring, which pulls the sliding column and the negative pressure plate downward, so that negative pressure is quickly formed inside the negative pressure chamber, so that the photovoltaic panel is quickly adsorbed by the clamping plate, so that the photovoltaic panel can be quickly installed under the hanging arm, which is convenient for subsequent work.

[0016] 3. The clamping block is connected to the negative pressure plate by a pull rope, so that when the negative pressure plate moves downward, the pull rope can be pulled to bring the two clamping blocks closer to each other, thereby clamping the two ends of the photovoltaic panel, further improving the installation stability and speed of the photovoltaic panel, and having the advantage of flexible operation.

[0017] 4. By setting a shift block, when the negative pressure plate slides upward, under the action of the inclined surface, the shift block can be slid to the outside of the counterweight seat until the lower part of the negative pressure plate is placed on the upper part of the shift block. Under the action of the elastic member, the shift block automatically rebounds, thereby clamping the negative pressure plate in the upper part of the negative pressure chamber. When the photovoltaic panel is installed on the clamping plate, the shift block is pulled out from the outside of the shift block to allow one end of the shift block to leave the bottom of the negative pressure plate. Then, through the contraction of the energized first spring, the negative pressure plate can be moved downward, thereby facilitating the rapid adsorption of the photovoltaic panel on the clamping plate.

[0018] 5. When installing the photovoltaic panel, the present invention lowers the movable frame on one side of the main body, and lowers the second steel rope on the side, so that one side of the clamping plate is lowered, so that the workers on the ground can first move one side of the photovoltaic panel to the side where the clamping plate is lowered, and then the rack on the other side controls the rotation of another movable frame to lower the other side of the clamping plate. The workers then move the other end of the photovoltaic panel to the clamping plate, thereby completing the installation, which is more convenient than the hook form of the prior art.

[0019] Other features and advantages of the present invention will be described in the following description, and part of them will become obvious from the description, or will be understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the written description and the accompanying drawings.

[0022] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used to explain the principles of the present invention together with the embodiments of the present invention.

[0023] Embodiment 1: Figure 1 , Figure 2 As shown, this embodiment provides a hoisting device for photovoltaic assembly installation, which can hoist the photovoltaic panel 5, and includes: A mobile vehicle 101 for movement, a base 102 is fixedly mounted on the tail box of the mobile vehicle 101, the base 102 is divided into an upper and a lower part, the upper and lower parts of the base 102 are rotatably connected by a bearing, so that the upper part of the base 102 can rotate relative to the lower part, and the lower part of the base 102 is fixedly mounted on the tail box of the mobile vehicle 101 by bolts; The base 102 is the rotating base of the crane, which is also usually called a rotator or a rotating base. It is a key component for realizing the rotation of the boom in the crane. It is installed at the connection between the crane base and the vehicle body. The boom can rotate freely within a certain range through a rotating mechanism. The rotating mechanism may include gears and a motor. The gears are installed on the upper half of the base 102, which is movable on the base 102. The motor drives the gears to rotate, so that the base 102 can achieve a rotating effect, thereby realizing all-round lifting and handling of goods. A boom 103 is installed above the base 102, one end of the boom 103 is rotatably connected to the base 102, the boom 103 is divided into multiple sections, and the multiple sections of the boom 103 can be telescopically adjusted by hydraulic drive, so as to adapt to the hoisting work of photovoltaic panels 5 with different installation distances. A hydraulic rod 104 is arranged below a section of the boom 103 close to the base 102, the top of the hydraulic rod 104 is hinged to the two ends of the boom 103, and the bottom of the hydraulic rod 104 is slidably connected to the upper part of the tail box of the mobile vehicle 101; like Figure 3 , Figure 4 As shown, a clamping assembly 2 is provided at the top of the boom 103, and the clamping assembly 2 is used to clamp the photovoltaic panel 5 so that the photovoltaic panel 5 will not fall when it is lifted. The clamping assembly 2 specifically includes: Figure 5 The clamping plate 201 shown in the figure can be connected to the top of the boom 103 through a suspension rope, so that the clamping plate 201 can be lifted by the boom 103 to achieve the movement of the photovoltaic panel 5; Figure 6 The clamping block 202 shown is slidably mounted on both ends of the clamping plate 201, and a slide groove 203 is provided at both ends of the clamping plate 201. The clamping block 202 is slidably connected with the slide groove 203. The middle part of the clamping block 202 has a groove limiting structure, and the inner side of the slide groove 203 is provided with a limiting protrusion matching the groove limiting structure. The limiting protrusion plays the role of: when the clamping block 202 slides in the slide groove 203, the clamping block 202 will not be separated from the slide groove 203, thereby achieving a stable sliding effect; in the above scheme, the two clamping blocks 202 slide close to each other, so that the edge of the photovoltaic panel 5 is clamped by the protrusion and friction force on the upper part of the clamping block 202, thereby achieving a clamping effect on the photovoltaic panel 5; The counterweight seat 204 is connected to the middle of the lower part of the clamping plate 201. The counterweight seat 204 can make the clamping assembly 2 more stable. The counterweight seat 204 and the clamping plate 201 can be integrally formed or fixedly connected. The fixed connection method can be welding. Figure 7The negative pressure chamber 205 shown in the figure is opened inside the counterweight seat 204, the bottom of the negative pressure chamber 205 is closed, the top of the negative pressure chamber 205 passes through the upper part of the clamping plate 201, and the top of the negative pressure chamber 205 is provided with a filter plate 206, and the filter plate 206 is evenly provided with a plurality of through holes; through the above scheme, when the photovoltaic panel 5 is placed on the upper surface of the clamping plate 201, the bottom surface of the photovoltaic panel 5 is in close contact with the top surface of the clamping plate 201, thereby blocking the through holes on the filter plate 206 at the top of the negative pressure chamber 205, so that a closed space is formed inside the negative pressure chamber 205, and at this time, when negative pressure is formed in the negative pressure chamber 205, the photovoltaic panel 5 can be adsorbed on the upper part of the clamping plate 201, thereby preventing the photovoltaic panel 5 from falling; like Figure 7 , Figure 8 As shown, as a solution for the negative pressure chamber 205 to form negative pressure, it includes the following parts: The negative pressure plate 207 is installed inside the negative pressure chamber 205. The edge of the negative pressure plate 207 contacts the inner wall of the negative pressure chamber 205. When the negative pressure plate 207 slides downward, negative pressure is formed on the upper part of the negative pressure chamber 205, thereby adsorbing the photovoltaic panel 5. A sliding column 208 is fixedly connected to the lower part of the negative pressure plate 207. A first spring 210 is connected between the bottom of the sliding column 208 and the bottom of the inner wall of the negative pressure chamber 205. The first spring 210 is an electromagnetic spring that can shrink when powered on. The hanging block 209 is fixedly connected to the bottom of the sliding column 208 by a soft rope. The hanging block 209 mainly plays the role of a counterweight. Its role is to cooperate with the energized first spring 210 to form a downward pressure, pull the sliding column 208 and the negative pressure plate 207 downward, so that negative pressure is quickly formed inside the negative pressure chamber 205, so that the photovoltaic panel 5 is quickly adsorbed by the clamping plate 201, so that the photovoltaic panel 5 can be quickly installed under the suspension arm 103, which is convenient for subsequent work; The suction cup 213 is fixedly connected to the clamping plate 201. After the photovoltaic panel 5 is installed on the clamping plate 201, the photovoltaic panel 5 can be initially fixed by the initial adsorption of the suction cup 213 before the negative pressure chamber 205 generates negative pressure, so that the photovoltaic panel 5 will not slide easily.

[0024] like Figure 7 , Fig. 9As shown, the outer wall of the clamping block 202 is connected with a second spring 212, and the other end of the second spring 212 is fixedly connected to the inner wall of the slide groove 203. The second spring 212 is in a contracted state by default. In the absence of external force, the two clamping blocks 202 are in a state of moving away from each other. The ends of the two clamping blocks 202 that are close to each other are also connected with a pull rope 211, and the pull rope 211 runs from the inside of the clamping plate 201 to the negative pressure chamber 205, and the end of the pull rope 211 away from the clamping block 202 is connected to the top of the negative pressure plate 207. When the negative pressure plate 207 moves downward, the pull rope 211 can be pulled, so that the two clamping blocks 202 are close to each other, thereby clamping the two ends of the photovoltaic panel 5, and further improving the installation stability of the photovoltaic panel 5. like Fig. 9 As shown, in order to improve the smoothness of the clamping block 202 when sliding, pulleys are provided at both ends of the clamping block 202, and the pulleys can contact the top surface of the clamping plate 201. When the clamping block 202 slides, the pulleys can roll on the clamping plate 201, thereby reducing the sliding friction generated by the movement of the clamping block 202; like Figure 8 As shown, the side wall of the counterweight seat 204 is provided with a shifting block 214, and the shifting block 214 is slidably connected to the side wall of the counterweight seat 204. One end of the shifting block 214 located inside the negative pressure chamber 205 is provided with an inclined surface. An elastic member is connected between the shifting block 214 and the side wall of the counterweight seat 204. The elastic member can be a metal elastic sheet or a coil spring, so that the default state of the shifting block 214 can extend into the negative pressure chamber 205. At this time, when the negative pressure plate 207 slides upward Under the action of the inclined surface, the shift block 214 can be slid to the outside of the counterweight seat 204 until the lower part of the negative pressure plate 207 is placed on the upper part of the shift block 214. Under the action of the elastic member, the shift block 214 automatically rebounds, thereby clamping the negative pressure plate 207 in the upper part of the negative pressure chamber 205. When the photovoltaic panel 5 is installed on the clamping plate 201, the shift block 214 is pulled out from the outside of the shift block 214, allowing one end of the shift block 214 to leave the bottom of the negative pressure plate 207, so that the negative pressure plate 207 can move downward.

[0025] Embodiment 2: Fig.10 As shown, the technical solution of this embodiment is different from that of the first embodiment in that it further includes a balancing component 3 and a fine-tuning component 4, and the balancing component 3 includes: The main body 301 is installed below the top of the boom 103; A first steel rope 302 is fixedly connected to both ends of the top of the main body 301, and its top is connected to the upper end of the boom 103; Fig.12 The fixing frame 303 shown is fixedly connected to the bottom of the main body 301, and first guide wheels 306 are rotatably mounted at both ends of the fixing frame 303; A movable frame 304 is movably mounted on both ends of the main body 301, and a second guide wheel 307 is rotatably mounted on the end of the movable frame 304; Fig.11 The second steel ropes 305 shown in the figure have four pieces, and the four second steel ropes 305 are respectively arranged at the two ends of the main body 301, and the four second steel ropes 305 are fixedly connected to the bottom of the main body 301, and the four second steel ropes 305 respectively pass through the lower part of the first guide wheel 306 and the upper part of the second guide wheel 307 to extend to the four corners of the clamping plate 201, and the four corners of the clamping plate 201 are respectively provided with lifting ears, and the bottom ends of the four second steel ropes 305 are respectively fixedly connected to the four lifting ears; like Fig.12 , Fig.13 As shown, the upper part of the movable frame 304 is hingedly mounted on the middle part of the main body 301, and a gear 308 is connected to the middle part of the hinged position of the movable frame 304 and the main body 301. A cavity 311 is provided in the middle part of the main body 301, and the cavity 311 can adapt to the rotation of the gear 308. A rack 309 is also provided in the cavity 311, and the rack 309 is meshed with the gear 308. A third spring 310 is also connected between the bottom of the rack 309 and the bottom of the inner wall of the cavity 311. A sliding rod is connected to the top of the rack 309, and the sliding rod is sealed and slidably connected to the cavity 311. A first interface 312 is provided on the top of the cavity 311, and the first interface 312 is used to connect with an external hydraulic pipeline; It should be noted that the above-mentioned movable frame 304 is arranged on both sides of the main body 301, and there are also two racks 309. When the racks 309 move up and down, the gears 308 on both sides of the main body 301 can be rotated respectively, so that the movable frame 304 can be adjusted. The specific adjustment method is: when the movable frame 304 on one side of the main body 301 is lowered, the second steel rope 305 on this side is lowered, so that one side of the clamping plate 201 is lowered, so that the workers on the ground can first move one side of the photovoltaic panel 5 to the side where the clamping plate 201 is lowered, and then the rack 309 on the other side controls the rotation of the other movable frame 304 to lower the other side of the clamping plate 201, and the workers then move the other end of the photovoltaic panel 5 to the clamping plate 201, thereby completing the installation. It is more convenient than the hook form of the prior art; When installing the photovoltaic panel 5, one end of the clamping plate 201 is lowered, and the two corners of one end of the photovoltaic panel 201 are placed on the mounting frame. Then the other end of the clamping plate 201 is lowered, so that the other end of the photovoltaic panel 5 is placed on the mounting frame. Then the energized first spring 210 is de-energized. Under the upward recovery action of the first spring 210, the negative pressure of the negative pressure chamber 205 fails. Then the photovoltaic panel 5 is detached from the clamping plate 201, and the installation is completed. Compared with the installation method of the prior art, the photovoltaic panel 5 is more stable and convenient during the hoisting process.

[0026] like Fig.11 As shown, the fine-tuning component 4 includes: A sliding sleeve 401 is fixedly connected to the top of the boom 103; An adjusting column 402 is installed in the sliding sleeve 401; A sliding block 403 is fixedly connected to the middle of the adjusting column 402. The sliding block 403 is slidably installed in the middle of the sliding sleeve 401, and both ends of the sliding sleeve 401 also have sliding spaces; The second interface 404 is provided at both ends of the sliding sleeve 401 and is connected to an external hydraulic pipeline; Through the above scheme, when the second interface 404 on one side is injected with high-pressure liquid, the sliding block 403 can be pushed to one side, so that when the position of the photovoltaic panel 5 forms a slight lateral offset with the position of the ground mounting frame, the photovoltaic panel 5 on the entire clamping assembly 2 can be aligned with the mounting frame by adjusting the left and right movement of the column 402, so that the fine-tuning work can be completed without the need for the mobile vehicle 101 to move, thereby improving the installation efficiency of the photovoltaic panel 5.

[0027] Embodiment 3: The technical solution of this embodiment is different from that of Embodiment 2 in that this embodiment provides a method for hoisting a photovoltaic module, comprising the following steps: S1, the mobile vehicle 101 moves to the vicinity of the stacking position of the photovoltaic panel 5, and then controls the boom 103 to move the clamping plate 201 to above the photovoltaic panel 5; S2, the two movable frames 304 drive the two second guide wheels 307 to descend respectively, unwind the second steel rope 305, and make the two ends of the clamping plate 201 descend in sequence, and move the photovoltaic panel 5 onto the clamping plate 201; S3, the negative pressure chamber 205 on the clamping plate 201 generates negative pressure, adsorbing the photovoltaic panel 5 on the clamping plate 201, and the two clamping blocks 202 clamp the two ends of the photovoltaic panel 5; S4, the boom 103 moves the photovoltaic panel 5 to the location where it is to be installed; S5, the movable frame 304 then drives the two second guide wheels 307 to descend respectively, allowing the second steel rope 305 to unwind, and allowing the two ends of the clamping plate 201 to descend in sequence. When one end of the clamping plate 201 descends, the two corners of one end of the photovoltaic panel 201 are placed on the mounting frame, and then the other end of the clamping plate 201 descends, so that the other end of the photovoltaic panel 5 is placed on the mounting frame, and then the energized first spring 210 is de-energized. Under the upward recovery action of the first spring 210, the negative pressure of the negative pressure chamber 205 fails, and then the photovoltaic panel 5 is detached from the clamping plate 201 to complete the installation.
