Description

Technical Field

[0001] This utility model relates to the technical field of electric locomotives, specifically to an auxiliary device for locomotive traction seats. Background Technology

[0002] A locomotive traction seat auxiliary fixture is a device used to assist in the installation and removal of locomotive traction seats. It is usually made of angle steel welded together according to the mating dimensions of the traction seat and works in conjunction with a hydraulic lifting vehicle. It can automatically calibrate the height, improve accuracy and work efficiency, thereby saving production costs.

[0003] An auxiliary device for the traction seat of an electric locomotive, disclosed in publication number CN111453650A, includes a lifting assembly and a lifting seat, with the lifting seat installed above the lifting assembly. The upper surface of the lifting assembly is provided with a slot for connecting the lifting lug of the traction seat. The lifting assembly is used to adjust the vertical lifting height of the lifting seat.

[0004] The aforementioned document can automatically calibrate the height, avoiding manual calibration, greatly improving accuracy and work efficiency, thereby saving production costs. However, the lifting component in the aforementioned document requires two sets of servo motors to be used synchronously, which is not only costly but also prone to lifting errors. Furthermore, since it rotates through a screw, the threads on the screw need lubrication after prolonged use; otherwise, the threads may dry and break, affecting its use. Therefore, we propose a locomotive traction seat auxiliary device to solve the problems mentioned above. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a locomotive traction seat auxiliary device, including a housing 1, a base plate 4, a hydraulic rod 16, and a servo motor 18. A side plate 2 is fixed to the side of the housing 1, and an opening 3 is provided at the top of the housing 1. The base plate 4 is installed inside the lower part of the housing 1. Fixing blocks 5 are fixed at both the front and rear ends of the middle of the base plate 4. A first support rod 7 is rotatably connected to the fixing blocks 5 via a first shaft 6. A second support rod 8 is rotatably connected to the middle of the first support rod 7 via a second shaft 9. A third shaft 10 is rotatably connected above the second support rod 8, and a fourth shaft 11 is rotatably connected below the second support rod 8. The upper end of the first support rod 7 rotates... A fifth shaft 12 is connected to the slot 15 on the surface of the side frame 14. The first support rod 7 and the second support rod 8 are each provided in two sets. The two sets of first support rod 7 and second support rod 8 are symmetrically arranged about the central axis of the housing 1, so that when the first support rod 7 is folded, the fifth shaft 12 at its end slides on the slot 15 on the surface of the side frame 14. The fourth shaft 11 has the same structure as the first shaft 6. The fourth shaft 11 is composed of a shaft 1101 and a connecting block 1102. The shaft 1101 is fixed at the middle of both ends of the connecting block 1102, so that the fourth shaft 11 can move threadedly with the rotating screw 19, and the rotating screw 19 can rotate on the first shaft 6.

[0022] Please see Figure 1-4The third shaft 10 is rotatably connected to the inner side of the side frame 14, and a lifting seat 13 is fixed on the top of the side frame 14. The two ends of the side frame 14 are provided with slots 15, and the two ends of the lifting seat 13 are provided with bayonets 17. The bottom plate 4 is equipped with hydraulic rods 16 at both the front and rear ends between the two sets of fixed blocks 5, and the upper end of the rods 16 is connected to the lifting seat 13. A servo motor 18 is fixed on one side of the middle part of the bottom plate 4, and a rotating screw 19 is fixed at the output end of the servo motor 18. The threads on the surface of the rotating screw 19 are symmetrically arranged about itself, and the rotating screw 19 is rotatably connected to the first shaft 6. The rotating screw 19 is threadedly connected to the connecting block 1102 on the fourth shaft 11, which can easily rotate the screw 19 to drive the fourth shaft 11 to move threadedly, so that the first support rod 7 and the second support rod 8 can be folded.

[0023] Please see Figure 1-4 A lubrication assembly 20 is installed on one side of the inner side of the housing 1. The lubrication assembly 20 includes an oil supply tank 2001, which is fixed inside the housing 1. An oil pump 2002 is installed above the oil supply tank 2001. One end of the oil pump 2002 is connected to the bottom of the oil supply tank 2001 through an oil extraction pipe 2003. The other end of the oil pump 2002 is connected to an oil drain pipe 2004 fixed on the surface of the base plate 4. A control valve 2006 is installed on the surface of the oil drain pipe 2004 to facilitate oil supply for lubrication. The oil drain pipe 2004 is located above the rotating lead screw 19. Oil drip ports 2005 are opened at both ends of the lower part of the oil drain pipe 2004, corresponding to the threads on the surface of the rotating lead screw 19. This allows lubricating oil to be dripped onto the threads on the surface of the rotating lead screw 19 through the oil drip ports 2005, thereby lubricating the rotating lead screw 19 and improving its service life.

[0024] Working principle: First, during use, the servo motor 18 can be turned on, causing the servo motor 18 to drive the rotating screw 19 to rotate. The rotating screw 19 then drives the connecting blocks 1102 on the two sets of fourth shafts 11 on the base plate 4 to move threadedly. When the fourth shafts 11 move, they will drive the first support rod 7 and the second support rod 8 to fold, which facilitates the fifth shaft 12 above the first support rod 7 to engage and slide on the slots 15 at both ends of the side frame 14 below the lifting seat 13, so that the lifting seat 13 can be raised. The thread teeth at both ends of the rotating screw 19 are symmetrically distributed about itself, and the first support rod 7 and the second support rod 8 on the base plate 4 are also symmetrically distributed about themselves, which facilitates the rotating screw 19 to drive the two sets of first support rods 7 and second support rod 8 to move synchronously. With the use of the hydraulic rod 16 below the lifting seat 13, the stability of the lifting seat 13 is improved.

[0025] During lubrication, the oil pump 2002 on the lubrication assembly 20 can be turned on so that the oil pump 2002 can drip lubricating oil onto the thread teeth on the surface of the rotating lead screw 19 through the oil drip port 2005 on the lower surface of the oil drain pipe 2004. This facilitates the lubrication of the rotating lead screw 19 and prevents the thread teeth on the surface of the rotating lead screw 19 from drying and cracking after long-term use. This is the operating principle of the locomotive traction seat auxiliary device.

[0026] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
