[0024] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0025] A crane lighting device includes a crane maintenance platform 1. A plurality of through grooves 15 are opened at the top and bottom of the crane maintenance platform 1. A limiting device 14 is arranged on the bottom of the crane maintenance platform 1 and on the outer surface of the plurality of through grooves 15. An elevating lamp socket plate 10 is arranged inside the limiting device 14. Limiting grooves 13 are opened on both sides of the inner surface of the limiting device 14. The limiting grooves 13 are slidably connected with limiting blocks 12. The inner sides of the two limiting blocks 12 are respectively connected to the outer sides of different elevating lamp socket plates 10;

[0026] At the top of the crane maintenance platform 1 and behind a number of through slots 15, a sliding guide rail 2 is provided. A sliding inner cavity 3 is opened on the front surface of the sliding guide rail 2. A lead screw 6 is opened at the centers of the top and bottom of the sliding inner cavity 3. A sliding plate 7 is sleeved on the surface of the lead screw 6. The sliding plate 7 is fitted and slidably connected in the sliding inner cavity 3. The front surface of the sliding plate 7 is connected to the top of the lifting lamp socket plate 10 through a connecting plate 8.

[0027] Further, a lamp socket 11 is provided at the center of the bottom of the lifting lamp socket plate 10.

[0028] Further, a driving motor 4 is provided at the center of the top of the sliding guide rail 2. The bottom output end of the driving motor 4 is connected to the top of the lead screw 6. A motor switch 5 is provided on one side of the top of the sliding guide rail 2. The motor switch 5 is electrically connected to the driving motor 4 fixed on the sliding guide rail 2 and is in the same circuit.

[0029] It should be noted that the electrical connection between the motor switch 5 and the driving motor 4 in the present utility model uses existing mature technologies, and the electrical connection structure and circuit diagram will not be described in detail herein.

[0030] Further, a fence 9 is provided on the top of the crane maintenance platform 1 and on the outer surface of a number of through slots 15. The top of the limit slot 13 penetrates the crane maintenance platform 1 and is inside the fence 9. The bottom of the limit slot 13 is above the bottom of the limiting device 14. Specifically, when the limit block 12 slides to the bottom of the limit slot 13, the bottom of the lifting lamp socket plate 10 will be on the same horizontal plane as the bottom of the limiting device 14, and it will not affect the illumination of the lighting lamp. The height of the limit slot 13 matches the height of the sliding inner cavity 3. Thus, when the bottom of the sliding plate 7 slides to the bottom of the sliding inner cavity 3, the lifting lamp socket plate 10 is located at the bottom of the limiting device 14. When the top of the sliding plate 7 slides to the top of the sliding inner cavity 3, the top of the lifting lamp base 10 will be on the same horizontal plane as the top of the fence 9. A number of gaps are provided on the surface of the fence 9 to facilitate the maintenance personnel to replace the lighting lamp.

[0031] Please refer to Figure 5 This utility model provides a technical solution:

[0032] A crane, including a crane lighting device as described above, further includes a fixed column 16, a crane running mechanism 17, a crane lifting appliance 18, and a roof truss 19. The two fixed columns 16 are symmetrically arranged. The bottom of the fixed column 16 is fixedly connected to the ground. The tops of the two fixed columns 16 are connected to both sides of the top of the roof truss 19. A crane maintenance platform 1 is fixedly connected to the inner sides of the two fixed columns 16. The top of the crane maintenance platform 1 is located at the bottom of the roof truss 19. A crane running mechanism 17 is fixedly connected to the top of the crane maintenance platform 1. A crane lifting appliance 18 is arranged at the center of the bottom of the crane maintenance platform 1. The crane lifting appliance 18 is connected to the crane running mechanism 17 through a towing rope.

[0033] Working principle: When maintenance personnel climb onto the crane maintenance platform 1, they can simultaneously perform maintenance on the crane running mechanism 17 and the lighting device. Among them, the maintenance of the crane running mechanism 17 is prior art, and its working principle will not be elaborated in detail here. For the maintenance of the lighting device, when maintenance is required, the staff comes to the sliding guide rail 2 here, and then turns on the motor switch 5 at the top. After the motor switch 5 is turned on, it will start the driving motor 4. The start of the driving motor 4 will cause the lead screw 6 to rotate, thereby causing the sliding plate 7 to move. The movement of the sliding plate 7 will cause the lifting lamp base 10 to move through the connecting plate 8, so that the lamp base 11 will move to the top of the crane maintenance platform 1, facilitating the removal of the lighting lamp at the lamp base 11 for maintenance and replacement.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
