The battery 3 is connected to the generator 19 through a circuit board and a corresponding circuit, and is used to store the electric energy generated by the generator 19. A limit frame 10 is fixed to the surface of the power supply box 2, and a lifting component is installed between the side wall of the power supply box 2 and the inside of the limit frame 10. A cross bar 21 is fixed on the top of the lifting component, and a symmetrically arranged conical lamp is installed on the surface of the cross bar 21 through a movable bracket. Seat 22, both side outer walls of the limit frame 10 are constructed with dovetail grooves 11, dovetail sliders 12 are slidably arranged in the dovetail grooves 11, and the side walls of the dovetail sliders 12 are installed with wire winding components, the wires connected between the battery 3 and the conical lamp holder 22 pass through the wire winding components, and the lifting components are used to change the height of the cross bar 21 and the conical lamp holder 22 to meet the needs of different working scenes. When the lifting components are adjusted, the height of the conical lamp holder 22 changes accordingly. Under the action of the dovetail grooves 11 and the dovetail sliders 12, the wire winding components can be adjusted and moved up and down to avoid excessive winding of one end of the wire when winding and wrapping the wire, resulting in the separation of the wire end from the connection point.
[0027] Specifically, the wire winding assembly includes a wire winding drum 13 which is fitted and fixed on the side wall of the dovetail slider 12. The outer periphery of the wire winding drum 13 is configured with a wire through-hole 17 in the same vertical direction. The inner wall of the wire winding drum 13 is rotatably mounted with a symmetrically arranged rotating shaft 14, and a winding shaft 16 is fixed between the ends of the rotating shaft 14. The outer periphery of the winding shaft 16 is configured with a straight through groove for the wire to pass through. A torsion spring 15 is installed between the outer periphery of the rotating shaft 14 and the inner wall of the wire winding drum 13 to facilitate the rotation of the rotating shaft 14. After the wire passes through the straight through groove, when the winding shaft 16 rotates with the rotating shaft 14 under the action of the torsion spring 15, the wire can be evenly wound around the outer periphery of the winding shaft 16.
[0028] Specifically, a protective frame 18 is installed on the surface of the lighting vehicle chassis 1, and the protective frame 18 is arranged on the outside of the generator 19. The protective frame 18 can shield the generator 19 from the outside to prevent pedestrians from colliding with the generator 19 or the generator 19 from being damaged by external objects. The protective frame 18 has a frame structure, which is convenient for crane equipment to lift it, thereby facilitating the lifting of the mobile lighting vehicle.
[0029] Specifically, the side wall of the power supply box 2 is nested with a side panel 4, and the outer wall of the side panel 4 is flush with the outer wall of the power supply box 2. The side panel 4 is provided to facilitate maintenance of the components inside the power supply box 2.
[0030] Specifically, the lifting assembly includes a height-adjusting motor 5 fitted on the side wall of the power supply box 2, a first bevel gear 6 is fixedly mounted on the end of the output shaft of the height-adjusting motor 5, a screw 8 extending to the inside of the limit frame 10 is rotatably mounted on the top of the power supply box 2 through a ball bearing, a second bevel gear 7 meshing and transmission connected to the first bevel gear 6 is fixedly mounted on the bottom of the screw 8, a lifting rod 9 is threadedly connected to the outer periphery of the screw 8 and can slide up and down against the inner wall of the limit frame 10, the top of the screw 8 is not higher than the top of the limit frame 10, a screw groove matching the screw 8 is arranged inside the lifting rod 9, when the screw 8 rotates, the lifting rod 9 and the screw 8 are relatively displaced, so that the lifting rod 9 moves up and down, thereby changing the height of the conical lamp holder 22.
[0031] Specifically, the wire reel 13 is disposed on a side of the limiting frame 10 close to the generator 19 , and the wire is distributed along with the wire reel 13 on a side of the limiting frame 10 close to the generator 19 .
[0032] Specifically, a traction frame 20 is welded and fixed to the end of the lighting vehicle underframe 1 , and the cross-section of the traction frame 20 is L-shaped, so that the lighting vehicle underframe 1 is conveniently connected to the traction vehicle through the traction frame 20 .
[0033] It should be noted that the utility model is a lighting vehicle that is easy to hoist and move. When in use, the lighting vehicle chassis 1 is fixed to the towing hook of the towing vehicle through the towing frame 20, and the lighting vehicle chassis 1 and the upper equipment are pulled by the towing vehicle to move. When performing outdoor lighting operations, the generator 19 is started in advance, and the generator 19 stores electric energy in the battery 3 and supplies power to the conical lamp holder 22 and the height adjustment motor 5. The lifting component is started according to the lighting range during the operation, and the output shaft of the height adjustment motor 5 is connected through the first bevel gear 6 and the second bevel gear 6. The meshing transmission of the bevel gear 7 drives the screw 8 to rotate, and the lifting rod 9 moves up and down in contact with the inner wall of the limit frame 10 under the action of the screw 8, thereby changing the lighting height of the conical lamp holder 22, thereby achieving the effect of adjusting the lighting range, and when the conical lamp holder 22 rises, the torsion spring 15 is stretched, and the wire wound around the outer periphery of the winding shaft 16 is slowly released. When the conical lamp holder 22 is reset, the torsion spring 15 drives the rotating shaft 14 and the winding shaft 16 to rotate, and winds the wire back around the outer periphery of the winding shaft 16 to avoid the wire being dragged on the ground.
