DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention. Example 1

[0027] A solar photovoltaic panel installation crane, see Figure 1-Figure 8As shown, it includes a moving plate 1, a moving wheel 2, a column 3, a track 4, a slide 5, a motor 6, a winding wheel 7, a steel rope 8, a pulley 9, a fixed frame 10, a fixed plate 11, an electric slide rail 12 and an electric clamp 13. A plurality of moving wheels 2 are slidably arranged on the moving plate 1, and the plurality of moving wheels 2 are distributed on the left and right sides of the moving plate 1. The moving plate 1 is provided with a column 3 by welding, and the column 3 is provided with a track 4 by welding. The slide 5 is slidably arranged on the track 4, and the slide 5 is provided with a motor 6 by bolt connection. The output shaft of the motor 6 is provided with a winding wheel by welding. A wire wheel 7 is provided, and a steel rope 8 is wound around the wire wheel 7. A pulley 9 is rotatably provided on the slide 5. The steel rope 8 is wound around the pulley 9. One end of the steel rope 8 is connected to a fixed frame 10. A fixed plate 11 is welded on the fixed frame 10. Two electric slide rails 12 are bolted on the fixed plate 11. Two electric clamps 13 for clamping the solar photovoltaic panel are slidably provided inside the electric slide rail 12. A slider 15 is also included. Two first slide grooves 14 are provided on the column 3. A slider 15 is slidably provided on the two first slide grooves 14. The slider 15 is connected to the fixed plate 11.

[0028] See also Figure 8 As shown, an elastic member 23 is also included, and the moving wheel 2 and the moving plate 1 are commonly connected with the elastic member 23 for buffering.

[0029] See also Figure 3 As shown, a limiting block 24 is also included. The limiting block 24 for limiting the steel rope 8 is arranged on the slide 5 by welding.

[0030] When the crane is needed, the staff places the solar photovoltaic panel on the movable plate 1, and then the staff turns on the electric slide rail 12, controls the electric clamp 13 to move inward to clamp the solar photovoltaic panel, and after clamping, the staff turns off the electric slide rail 12, and then the staff turns on the motor 6. The output shaft of the motor 6 rotates to drive the winding wheel 7 to rotate to reel in the steel rope 8, and then the steel rope 8 pulls the fixed frame 10 and the fixed plate 11 to move upward, so that the slider 15 moves upward along the first slide groove 14, and then the fixed plate 11 is limited to prevent the fixed plate 11 from driving the solar photovoltaic panel to shake and injure the staff, thereby reducing safety hazards. The limit block 24 is used to limit the steel rope 8 The limit is set to prevent the steel rope 8 from detaching from the pulley 9. When the fixed plate 11 moves upward to a suitable height, the staff turns off the motor 6 and then pushes the movable plate 1 to the side of the mounting frame. The movable wheel 2 rotates to reduce the friction between the movable plate 1 and the ground, making it easier for the staff to push the movable plate 1. When encountering an uneven ground, the movable wheel 2 moves up and down to deform the elastic member 23 to play a buffering role, reducing the vibration amplitude of the movable plate 1. Then the staff moves the slide 5 forward, so that the steel rope 8 pulls the fixed frame 10 and the fixed plate 11 forward, thereby placing the solar photovoltaic panel above the mounting frame, and the staff closes the track 4, thereby facilitating the installation of the solar photovoltaic panel on the mounting frame. Example 2

[0031] Based on Example 1, see Figure 5 As shown, it also includes a moving rod 17 and a support rod 18. Two second sliding grooves 16 are opened inside the moving plate 1. The two second sliding grooves 16 are distributed on the left and right sides of the moving plate 1. The moving rod 17 is slidably arranged inside the second sliding groove 16. The supporting rod 18 for supporting the moving plate 1 is rotatably arranged on the moving rod 17. The supporting rod 18 can be rotated to a suitable angle to contact the ground.

[0032] When pushing the moving plate 1 to the side of the mounting frame, the worker pulls the moving rod 17 forward and out of the moving plate 1, and then rotates the support rod 18 downward to contact the ground, thereby supporting the moving plate 1 to prevent the moving plate 1 from tipping over.

[0033] See also Figure 1 and Figure 6 As shown, it also includes a cylinder 19 and a sleeve plate 20. The cylinder 19 is provided on the track 4 by bolt connection, and the sleeve plate 20 is provided on the telescopic rod of the cylinder 19 by welding. The fixing plate 11 can be embedded in the sleeve plate 20, and the sleeve plate 20 slides on the column 3.

[0034] When the steel rope 8 pulls the fixed frame 10 and the fixed plate 11 to move upward, the fixed plate 11 is embedded in the sleeve plate 20. When pushing the movable plate 1 to the side of the mounting frame, the staff turns on the cylinder 19 and controls the telescopic rod of the cylinder 19 to shorten, so that the sleeve plate 20 drives the fixed plate 11 to move forward, thereby replacing the manual movement of the slide 5.

[0035] See also Figure 7 As shown, a trigger plate 21 and an alarm 22 are also included. The trigger plate 21 is provided inside the column 3 by bolt connection, and the trigger plate 21 is connected to the alarm 22 for issuing an alarm.

[0036] When the slider 15 moves upward, the slider 15 contacts the trigger plate 21, so that the trigger plate 21 transmits information to the alarm 22, so that the alarm 22 lights up and sounds an alarm to remind irrelevant people around to stay away from the moving plate 1 and prevent irrelevant people from approaching the moving plate 1.

[0037] It should be understood that the above description is only for exemplary purposes and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be included within the scope of the claims herein.
