Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This specific embodiment is a mobile generator set, and its structural schematic diagram is shown below. Figures 1 to 4As shown, the system includes a frame frame 1, with support columns 2 fixed to the lower ends of both sides of the frame frame 1. Guide wheels 3 are installed at the bottom of the four support columns 2. Reinforcing frames 4 are fixed to the inner sides of the two support columns 2. A hollow groove 5 is formed in the middle of the frame frame 1, and preset grooves 6 are formed around the inside of the frame frame 1. A lifting mechanism 7 is installed inside the multiple preset grooves 6 and inside and outside the frame frame 1. The lifting assembly 71 includes a motor 711, which is installed on one side of the frame frame 1. A first rotating rod 712 is installed at the output end of the motor 711, and a first synchronous pulley 713 is fixed around one end of the first rotating rod 712. A synchronous belt 714 is sleeved around the first synchronous pulley 713. A second synchronous pulley 715 is engaged on the inner side of the other side of belt 714. A second rotating rod 716 is fixedly mounted in the middle of the second synchronous pulley 715. First bevel gears 717 are fixedly mounted on both sides of the middle of the first rotating rod 712 and the second rotating rod 716. A second bevel gear 718 is engaged on one side of multiple first bevel gears 717. A transmission screw 719 is fixedly mounted in the middle of multiple second bevel gears 718. A screw sleeve 7110 is screwed around one side of each of the four transmission screws 719. Four screw sleeves 7110 are provided, and the four screw sleeves 7110 are respectively located on both sides of the bearing housing 8 and are fixedly connected to it. The bearing housing is fixedly mounted on the inner side of the four screw sleeves 7110. 8. A generator set 9 is installed in the middle of the support box 8, and second slots 11 are provided on both sides of the support box 8. Locking mechanisms 10 are installed on both sides of the frame frame 1. Lifting components 71 are installed inside multiple preset slots 6 and inside and outside the frame frame 1. Guide rods 72 are fixed inside one pair of preset slots 6. The guide rods 72 are movably guided to the support box 8. Anti-slip pads 73 are fixed to the bottom of the support box 8. The anti-slip pads 73 are fixed to the bottom of the support box 8. When the generator set 9 moves to the placement location with the moving components provided on both sides of the frame frame 1, the personnel can start the motor 711 to rotate the first rotating rod 712. A first synchronous motor is fixed around one end of the first rotating rod 712. The wheel 713 will rotate accordingly. At this time, the synchronous belt 714 meshing with the synchronous wheel will drive the second synchronous wheel 715 and the second rotating rod 716 in the middle to rotate. As a result, the two rotating rods will drive the first bevel gears 717 on their respective sides to rotate synchronously. The second bevel gears 718 meshing with the four first bevel gears 717 will drive the transmission screws 719 in the middle to rotate. As a result, the corresponding screw sleeves 7110 that interact with the four screws can carry the bearing housing 8 and the generator set 9 inside to descend along the hollow groove 5 with the guide rod 72 until the anti-slip pad 73 at the bottom of the bearing housing 8 is in contact with the ground, thereby fixing the position of the bearing housing 8 and the generator set 9.

[0028] The locking mechanism 10 includes a mounting frame 101, which is located on both sides of the frame 1. A threaded groove 102 is formed in the middle of the mounting frame 101, and a threaded bolt 103 is threaded into the middle of the threaded groove 102. A rotating shaft 104 is connected to the top of the threaded bolt 103, and a guide frame 105 is connected to the other end of the rotating shaft 104. Guide grooves 106 are formed on both sides of the mounting frame 101, and the guide frame 105 is connected to the guide grooves 106 on both sides of the mounting frame 101. Locking support rods 107 are fixed on both sides of the inner end of the guide frame 105. First slots 108 are formed on both sides of the frame 1, and the first slots 108 are approximately the same size as the second slots 11. All are connected to the locking support rod 107 in a snap-fit ​​manner. When it is necessary to adjust the position of the bearing housing 8 and the generator set 9, the lifting mechanism 7 can be used to raise the bearing housing 8. After it is raised to the corresponding height, the personnel manually tighten the threaded bolt 103. Since the rotating shaft 104 at the end of the threaded bolt 103 is movably connected to the guide frame 105, when the threaded bolt 103 is in the state of interacting with the screw groove 102 in the middle of the fixed frame 101, the guide frame 105 and the locking support rods 107 on both sides of its inner end can be guided and aligned with the guide groove 106 and inserted into the first slot 108 of the frame 1 and the second slot 11 of the bearing housing 8, thereby assisting in the bearing support of the bearing housing 8 and improving safety.

[0029] Working principle: When the generator set 9 moves to the placement location along with the moving components on both sides of the frame 1, the operator can start the motor 711 to rotate the first rotating rod 712. The first synchronous pulley 713 fixed around one end of the first rotating rod will rotate accordingly. At this time, the synchronous belt 714 meshing with the synchronous pulley will drive the second synchronous pulley 715 and the second rotating rod 716 in the middle to rotate. Thus, the two rotating rods will drive the first bevel gears 717 on their respective sides to rotate synchronously. The second bevel gears 718 meshing with the four first bevel gears 717 will drive the transmission screws 719 in the middle to rotate. Thus, the corresponding screw sleeves 7110 that interact with the four screws can carry the bearing housing 8 and the generator set 9 inside, guided by the guide rod 72, to descend along the hollow groove 5 until... The anti-slip pad 73 at the bottom of the bearing housing 8 can be placed against the ground to fix the position of the bearing housing 8 and the generator set 9. When the position of the bearing housing 8 and the generator set 9 needs to be adjusted later, the lifting mechanism 7 can be used to raise the bearing housing 8. After it is raised to the corresponding height, the threaded bolt 103 is manually turned. Since the rotating shaft 104 at the end of the threaded bolt 103 is movably connected to the guide frame 105, when the threaded bolt 103 is in the state of interacting with the screw groove 102 in the middle of the fixed frame 101, the guide frame 105 and the locking support rods 107 on both sides of its inner end can be guided and inserted into the first slot 108 of the frame 1 and the second slot 11 of the bearing housing 8 in coordination with the guide groove 106. This helps to support the bearing housing 8 and improve safety.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
