DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] See also Figures 1 to 4 The utility model provides a technical solution: a dual-motor electric lifting frame for a locomotive, comprising a mounting frame 1 connected to the frame, transmission assemblies 3 are symmetrically arranged at both ends of the mounting frame 1, and motors 4 are connected to the sides of the two transmission assemblies 3, and the output ends of the motors 4 are connected to the transmission assemblies 3 to form a reduction motor, and the motors 4 drive the transmission assemblies 3 to operate, and two rotating shafts 6 are rotatably connected to the two sides of the lower end of the mounting frame 1, and the outer ends of the two rotating shafts 6 are connected to the rotating gears 2 and the supporting assemblies 5, and the rotating shafts 6 rotate with the rotating gears 2 and the supporting assemblies 5 at the same time, and the rotating gears 2 are meshed with the transmission assemblies 3, and the motors 4 on both sides run synchronously, and the motors 4 drive the transmission assemblies 3 to operate and drive the rotating gears 2 and the supporting assemblies 5 to rotate. When the supporting assemblies 5 rotate to a vertical position, the vehicle body is lifted and supported, so that the locomotive can be parked stably and is easy to maintain. When the supporting assemblies 5 rotate to a horizontal position, the supporting assemblies 5 are in a retracted state and no longer support the locomotive, thereby reducing the influence of the supporting assemblies 5 on the normal driving of the locomotive.

[0024] like Figure 3 and 4As shown, the transmission assembly 3 includes a base plate 32, a shell 31 and a cover plate 37. The base plate 32 is connected to the end surface of the mounting frame 1 through fasteners, the shell 31 is fixed on the base plate 32, the motor 4 is connected to the side of the shell 31, and the base plate 32 is rotatably connected with a first gear 33 and a second gear 34 through a pin shaft. The rotating gear 2 is meshed with the first gear 33, and a first transmission shaft 38 is provided at the lower end of the second gear 34. The first transmission shaft 38 is rotatably connected to the cover plate 37, and the first transmission shaft 38 is connected to the third gear 35 and the fourth gear 36. 6, the second gear 34 is meshed with the third gear 35, and the fourth gear 36 is meshed with the output end of the motor 4. The motor 4 can drive the fourth gear 36 to rotate, so that the first transmission shaft 38 and the third gear 35 rotate together. Because the second gear 34 is meshed with the third gear 35, the second gear 34 and the first gear 33 located on the same pin shaft as the second gear 34 are further driven to rotate, thereby rotating the rotating gear 2. The rotating gear 2 and the supporting assembly 5 are sleeved on the same rotating shaft 6, thereby rotating the supporting assembly 5 to lift the locomotive.

[0025] The support assembly 5 includes a support leg 51 sleeved on the rotating shaft 6, the angle of the support leg 51 is controlled by the rotating shaft 6, the support leg 51 is connected to the rotating gear 2 by fasteners, the support leg 51 rotates synchronously with the rotating gear 2, and a support foot 53 is formed at the lower end of the support leg 51, and the support foot 53 is L-shaped, which enhances the contact area between the support foot 53 and the ground, thereby further improving the supporting stability of the support assembly 5.

[0026] A guide wheel 52 is rotatably connected to the surface of the leg 51 via a pin shaft. The guide wheel 52 is located above the leg 53. When the leg 51 contacts the ground, the guide wheel 52 will contact the ground first, while increasing the distance between the leg 53 and the ground, thereby preventing the leg 51 from interfering with the ground after landing, making it difficult for the leg 51 to rotate.

[0027] The rotating gear 2 is a sector gear, and the sector angle of the rotating gear 2 is at least 90 degrees, so that the rotation stroke of the support assembly 5 is greater than 90 degrees, so that the support assembly 5 can meet the use requirements of the locomotive.

[0028] like Figure 5 As shown, a mounting plate 11 is formed on the side of the mounting frame 1, and the transmission assembly 3 is fixed on the mounting plate 11. A first limiting boss 12 and a second limiting boss 13 are formed on the outer side of the mounting plate 11. The end faces of the first limiting boss 12 and the second limiting boss 13 are flush with the outer end face of the rotating gear 2. The first limiting boss 12 and the second limiting boss 13 are respectively used to limit the rotation stroke of the rotating gear 2 to further control the rotation stroke of the support assembly 5. At the same time, the first limiting boss 12 and the second limiting boss 13 support the support assembly 5 to enhance the rigidity of the support assembly 5.

[0029] A connecting plate 7 is also fixed to the mounting frame 1. The connecting plate 7 has a C-shaped cross section and is connected to and wrapped around the crossbeam of the vehicle frame, thereby increasing the contact area with the vehicle frame and improving the connection strength.

[0030] Embodiment 2

[0031] like Figure 6 As shown, the two rotating shafts 6 can be connected together to form a full-length rotating shaft, connecting the support assemblies 5 on both sides together, so that the support assemblies 5 on both sides run synchronously, so that the forces on both ends of the locomotive are evenly distributed, thereby improving the stability of the locomotive.

[0032] 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. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
