[0031] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0032] like Figure 1 , Figure 2 and Figure 3As shown, a vehicle-mounted generator loading and unloading device includes a pair of rails 1 and a detachable slide rail 2 mounted on the floor 00 of a vehicle compartment. The upper end of the slide rail 2 can connect with the rail 1, and the lower end of the slide rail 2 can rest on the ground. The floor 00 of the vehicle compartment is provided with a positioning structure for limiting the generator 00, and the positioning structure is located on the side of the rail 1. The bottom of the generator 00 is provided with rollers 3 that can cooperate with the slide rail 2. One end of the generator 01 is connected to a traction rope 4, and the other end of the traction rope 4 is connected to an automatic retraction mechanism 10 inside the vehicle compartment 02. The interior of the vehicle compartment 02 is provided with a guide assembly for guiding the traction rope 4. The slide rail adopts a segmented ladder structure, with the two side slide rails connected by multiple crossbeams, and the top protrusion cooperates with the rollers. The upper section of the slide rail is inserted into the end of the track beforehand, the middle section of the slide rail is laid on the ground, and the lower section of the slide rail is placed on the ground. Then, the generator is placed on the lower section of the slide rail, and the automatic retraction mechanism is started to pull the generator through the traction rope. Under the guidance of the guide component, the generator moves along the slide rail into the carriage. Finally, the positioning structure is used to position the generator to ensure that the generator is firmly fixed in the carriage.

[0033] As a preferred structure, such as Figure 4 As shown, the automatic winding and unwinding mechanism 10 includes a housing 101, a motor 102, and a reel 103 for winding the traction rope 4. The housing 101 is located outside the motor 102 and the reel 103. The bottom of the housing 101 has an opening for the traction rope 4 to pass through. The output shaft of the motor 102 is connected to the reel 103. The housing 101 is equipped with a power control button and a button 104 for controlling the start and stop of the motor. With this structure, the operator only needs to control the winding and unwinding of the traction rope through the button, making operation simple and convenient.

[0034] In specific embodiments of this utility model, such as Figure 2 , 3 As shown in Figures 5 and 6, the guiding assembly includes a guide wheel, a first fixed pulley 6, a second fixed pulley 7, and a third fixed pulley 8. The guide wheel 5 is positioned between two tracks 1 and inside the carriage door. The first fixed pulley 6 is mounted on a first bracket 9 on the outer side of the end of track 1 inside the carriage 02. The second fixed pulley 7 is mounted on a second bracket 11 on the side of the first fixed pulley 6. The third fixed pulley 8 is mounted on the lower part of the support frame 12 outside track 1. The heights of the first fixed pulley 6, the second fixed pulley 7, and the third fixed pulley 8 are matched. The center lines of the first fixed pulley 6 and the second fixed pulley 7 are vertically aligned, while the center line of the third fixed pulley 8 is horizontally aligned. The automatic retraction mechanism 5 is located on the upper part of the support frame 12 and directly above the third fixed pulley 8. The traction rope, guided by the above-mentioned guiding assembly, can transmit the direction of traction force, enabling the smooth loading and unloading of the generator.

[0035] Further optimize the above structure, such as Figure 5 As shown, the lower part of the first bracket 9 is provided with a hanging ring for fixing the end of the traction rope 4, and the hanging ring is located below the first fixed pulley 6; the end of the generator 01 is provided with a movable pulley 13 that cooperates with the traction rope 4, and the end of the traction rope 4 passes sequentially around the third fixed pulley 8, the second fixed pulley 7, the first fixed pulley 6 and the movable pulley 13 and is connected to the hanging ring. By setting the movable pulley, the traction speed of the generator can be reduced, ensuring that the generator moves smoothly.

[0036] In specific embodiments of this utility model, such as Figure 5-7 As shown, the positioning structure includes a positioning block 14, a positioning rod 15, and a self-locking mechanism. The positioning block 14 and the self-locking mechanism are located between two tracks 1 and on the outside of the generator 01 position inside the carriage 02. The positioning rod 15 can pass through the protrusion 16 on the side wall of the generator 01 and engage with the positioning hole in the middle of the positioning block 14. The self-locking mechanism is used to fix the generator 01. The upper end of the positioning rod 15 is provided with an end cap, and the middle of the protrusion 16 is provided with a through hole that matches the positioning rod 15. The size of the end cap is larger than the diameter of the through hole. When the generator travels along the tracks to its placement position inside the carriage, the positioning rod is inserted into the positioning block, and the protrusion uses the self-locking mechanism to position the generator, ensuring that the generator is firmly fixed inside the carriage.

[0037] In specific design, such as Figure 7As shown, the self-locking mechanism includes a positioning platform 17, a support 18, a swing rod 19, and a positioning pin 20. The positioning platform 17 is disposed on the outer wall of the generator 01. The lower end of the swing rod 19 is rotatably connected to the support 18. The height of the support 18 is the same as the height of the track 1. The side of the swing rod 19 is provided with a protruding tongue 21, and the positioning pin 20 can connect the positioning platform 17 and the protruding tongue 21. The self-locking mechanism also includes a positioning shaft 22. There are two of each of the support 18 and the swing rod 19. The top of the swing rod 19 is provided with connecting holes that match the two ends of the positioning shaft 22. The two ends of the positioning shaft 22 are provided with limiting holes for engaging with the pin. The pin is disposed on the outer side of the swing rod 19. The positioning pin 20 has a raised edge at its upper end, and the positioning platform 17 has a stepped hole in its middle that matches the positioning pin 20. The upper diameter of the stepped hole is smaller than the lower diameter, and the outer diameter of the raised edge is larger than the upper diameter of the stepped hole. The lower part of the stepped hole has a spring 23 that can be fitted onto the positioning pin 20, and the outer diameter of the spring 23 is between the upper and lower diameters of the stepped hole. The top edge of the tongue 21 has a guide slope, and the top surface of the tongue 21 has a limiting hole that cooperates with the positioning pin 20. At the same time, the upper end of the rocker arm 19 is rotatably engaged with the crank 24, and the end of the crank 24 is rotatably engaged with the crank handle 25. The rocker arm 19 can be easily driven to swing up and down by the crank handle 25. When the generator is in place, the crank handle is turned to make the rocker arm stand upright, the two positioning pins are inserted into the two protruding tongues on both sides, and then the positioning shaft is inserted into the connecting holes of the two rocker arms on both sides to securely lock the generator.

[0038] To facilitate the loading and unloading of the generator, a detachable base 24 can be installed at the bottom of the generator 01. The roller 3 is located at the bottom of the base 24, and the traction rope 4 is connected to the base 24. The generator 01 can be fixed to the base 24 with bottom bolts. An upright baffle (not shown in the figure) is fixed to the rear side of the base 24. The protrusion 16 and positioning platform 17 can be installed on the outside of the baffle, eliminating the need to pre-reserve the protrusion 16 and positioning platform 17 on the side of the generator 01, which makes installation and unloading more convenient.

[0039] To further optimize the above scheme, one outer end of the track 1 is rotatably connected to the bottom of the carriage 02. An electric hoist 25 is installed on the inner top wall of the carriage 02. The end of the wire rope of the electric hoist 25 is connected to the inner side of the track 1. The electric hoist 25 is used to pull the track 1 so that it tilts downwards towards the exit end of the carriage 02. In specific manufacturing, the first bracket can be connected to the track via a connecting rod. The tilting progress of the track is adjusted by the electric hoist, and the convex tongue drives the first bracket to tilt accordingly, avoiding interference from the traction rope. After the track tilts, it facilitates the smooth transition of the generator between the track and the slide rail, reducing the difficulty of loading and unloading the generator.

[0040] In summary, this utility model has the advantages of reasonable design, compact structure, and convenient and quick operation. In use, the upper section of the slide rail is connected to the track, the lower section of the slide rail is placed on the ground, and the generator is placed on the slide rail. Starting the motor pulls the generator via a traction rope, which, guided by the guide assembly, moves the generator along the slide rail. When the generator reaches the carriage door, the electric hoist is activated to tilt the track to a certain extent, allowing the generator to smoothly enter its position on the track. Then, the positioning rod is inserted into the positioning block, and the two positioning pins are inserted into the protruding tabs on both sides. The positioning shaft is inserted into the connecting holes of the swing arms on both sides to securely lock the generator, ensuring it is firmly fixed inside the carriage. This utility model has a high degree of automation, improving work efficiency and reducing the labor intensity of workers.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
