[0021] See also Figure 1 and Figure 4 The utility model provides a technical solution: a single-motor electric lifting frame of a locomotive, comprising a mounting frame 2 connected to a frame, the mounting frame 2 is connected to the frame by fasteners, a first transmission assembly 5 is fixed at one end of the mounting frame 2, a motor 6 is connected to the first transmission assembly 5, an output end of the motor 6 is connected to the first transmission assembly 5 to form a reduction motor, the motor 6 can drive the first transmission assembly 5 to operate, a rotating shaft 3 is rotatably connected to the lower end of the mounting frame 2, a rotating gear 55 and two supporting assemblies 4 are sleeved on the rotating shaft 3, the two supporting assemblies 4 are respectively sleeved at both ends of the rotating shaft 3 and located on both sides of the mounting frame 2, the supporting assembly 4 is connected to the rotating gear 55 to rotate together, the rotating gear 55 is meshed with the gear inside the first transmission assembly 5, the motor 6 drives the first transmission assembly 5 to operate and drives the rotating gear 55 and the supporting assembly 4 to rotate, when the supporting assembly 4 is in a vertical state, the supporting assembly 4 can lift and support the frame, so that the locomotive can be parked stably and convenient for maintenance, when the supporting assembly 4 is in a horizontal state, the supporting assembly 4 is in a retracted state, the frame will not be subjected to supporting force, and can travel normally.

[0022] like Figure 2 and 3As shown, the first transmission assembly 5 includes a base plate 57, a cover 51 and a cover plate 58. The base plate 57 is connected to the end surface of the mounting frame 2 by fasteners, and the cover 51 is also fixed to the base plate 57 by fasteners. The housing of the motor 6 is connected to the side of the cover 51 by fasteners. The base plate 57 is rotatably connected to the third transmission gear 54 and the fourth transmission gear 56 by a pin shaft. The rotating gear 55 is meshed with the fourth transmission gear 56. The lower end of the third transmission gear 54 is provided with a first transmission shaft 53, and the first transmission shaft 53 is rotatably connected to the cover plate 58. The first transmission shaft 53 is connected to the second transmission gear 531 and the first transmission gear 52 by a key. The wheel 531 is meshed with the third transmission gear 54, and the first transmission gear 52 is meshed with the output end of the motor 6. The operation of the motor 6 will drive the first transmission gear 52 to rotate, so that the first transmission shaft 53 and the second transmission gear 531 thereon will rotate, and the second transmission gear 531 will drive the third transmission gear 54 to rotate. The third transmission gear 54 and the fourth transmission gear 56 are both connected to the same pin shaft, and the two rotate synchronously, so that the fourth transmission gear 56 will also rotate, further driving the rotating gear 55 and the rotating shaft 3 to rotate, and the rotation of the rotating shaft 3 will cause the support assembly 4 to rotate, thereby controlling the rotation angle of the support assembly 4 and adjusting the lifting height of the locomotive.

[0023] like Figure 2 and 4 As shown, the support assembly 4 includes a support leg 41 sleeved on the rotating shaft 3. The rotation of the rotating shaft 3 will drive the support leg 41 to rotate, thereby adjusting the angle of the support leg 41. The support leg 41 is connected to the rotating gear 55, and the rotating gear 55 will also drive the support leg 41 to rotate. A support foot 43 is formed at the lower end of the support leg 41, and the support foot 43 is L-shaped, which enhances the contact area between the support foot 43 and the ground, and further improves the support stability of the support assembly 4.

[0024] A guide wheel 42 is rotatably connected to the surface of the leg 41 via a pin shaft. The guide wheel 42 is located above the leg 43. When the leg 41 contacts the ground, the guide wheel 42 will contact the ground first, while increasing the distance between the leg 43 and the ground, thereby preventing the leg 41 from interfering with the ground after landing, making it difficult for the leg 41 to rotate.

[0025] The rotating gear 55 is a sector gear, and the sector angle of the rotating gear 55 is at least 90 degrees, so that the movement stroke of the support assembly 4 is also greater than 90 degrees, so that the support assembly 4 can meet the use requirements of the locomotive.

[0026] like Figure 5As shown, a mounting plate 21 is formed on the side of the mounting frame 2, and the first transmission assembly 5 is fixed on the mounting plate 21. A first limiting boss 22 and a second limiting boss 23 are formed on the outer side of the mounting plate 21. The end faces of the first limiting boss 22 and the second limiting boss 23 are both flush with the outer end face of the rotating gear 55. The first limiting boss 22 and the second limiting boss 23 are used to limit the rotation stroke of the rotating gear 55 respectively, and the rotation angle of the rotating gear 55 is controlled, so that the support assembly 4 can rotate between vertical downward and horizontal states.

[0027] A connecting plate 1 is also fixed to the mounting frame 2. The connecting plate 1 has a C-shaped cross section and is connected to and wrapped around the crossbeam of the frame, thereby increasing the contact area with the frame and enhancing the connection strength with the frame.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
