[0002] The locomotive spring damping buffer device is a shock absorption and buffer device specifically designed for locomotives. It combines the elasticity of springs with the resistance characteristics of dampers to effectively absorb impact forces and reduce vibrations.

[0003] Currently, existing locomotive spring damping buffer devices typically utilize the energy storage characteristics of spring elastic deformation and the energy dissipation characteristics of dampers for buffering. However, the springs and dampers in traditional locomotive spring damping buffer devices often need to be used in conjunction with brackets and buffer seats. Since the springs and dampers are usually installed internally, when the internal springs and dampers need to be inspected after long-term use, it takes a lot of time for the staff to complete the work, thus reducing the convenience of device maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a novel spring damping buffer device for electric locomotives, aiming to solve the problem that existing spring damping buffer devices in the prior art typically utilize the energy storage characteristics of spring elastic deformation and the energy dissipation characteristics of dampers for buffering. However, the springs and dampers in traditional electric locomotive spring damping buffer devices often need to be used in conjunction with brackets and buffer seats. Since the springs and dampers are usually installed internally, after long-term use, when it is necessary to inspect and maintain the internal springs and dampers, the staff needs to spend a lot of time to complete the task, thus reducing the convenience of device maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel electric locomotive spring damping buffer device, comprising a buffer seat, wherein multiple hydraulic dampers are installed inside the buffer seat, one end of each hydraulic damper is connected to a buffer head, an alloy spring is sleeved on the outer wall of each hydraulic damper, and an inspection port is provided on the top of the buffer seat.

[0006] The inspection port has positioning grooves at both ends, and a limit slot is provided on the inner side of the positioning groove. A top plate is provided on the inner side of the inspection port, and mounting bases are connected to both ends of the top plate. A bidirectional lead screw is rotatably connected inside the mounting base. Two threaded connecting blocks are threaded to the outer wall of the bidirectional lead screw. Limiting blocks are connected to the outer walls of the two threaded connecting blocks. A guide rod is connected inside the mounting base.

[0007] As a preferred embodiment of the novel electric locomotive spring damping buffer device of this utility model, the mounting base can be embedded inside the positioning groove, and the positioning groove is connected to the inspection port.

[0008] As a preferred embodiment of the novel electric locomotive spring damping buffer device of this utility model, the end of the limiting plug away from the threaded connecting block is adapted to the size of the limiting slot.

[0009] As a preferred embodiment of the novel electric locomotive spring damping buffer device of this utility model, the outer wall of the bidirectional lead screw is connected with a first bevel tooth, the top of the mounting base has a knob that passes through it, and the through end of the knob is connected with a second bevel tooth.

[0010] In a preferred embodiment of this novel electric locomotive spring damping buffer device, the first bevel tooth and the second bevel tooth mesh with each other.

[0011] As a preferred embodiment of the novel electric locomotive spring damping buffer device of this utility model, the buffer head has mounting grooves at both ends, a pulley is rotatably connected to the inner side of the mounting groove, and a sliding groove is formed on the inner wall of the buffer seat.

[0012] In a preferred embodiment of this novel electric locomotive spring damping buffer device, one side of the pulley is located inside the slide groove, and the buffer head can form a sliding connection structure with the buffer seat through the mounting groove, pulley, and slide groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

At this time, the two threaded connecting blocks connected by the thread on the outer wall will drive the limit plug to move towards each other along the guide rod, and one end of the limit plug will disengage from the limit slot. Then, by lifting the top plate with the knob, the inspection port can be opened, which makes it convenient for staff to inspect the internal hydraulic damper and alloy spring.

In addition, the pulleys will also slide along the sliding channels when the buffer head is subjected to force, thereby playing a guiding role and improving the stability of the buffer head when it is subjected to force.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-5 The present invention provides the following technical solution: a novel electric locomotive spring damping buffer device, including a buffer seat 1, a plurality of hydraulic dampers 2 installed inside the buffer seat 1, a buffer head 3 connected to one end of the plurality of hydraulic dampers 2, an alloy spring 4 sleeved on the outer wall of the plurality of hydraulic dampers 2, and an inspection port 5 opened on the top of the buffer seat 1.

[0025] Among them, the alloy spring 4 adopts a variable stiffness design. The initial stiffness is small, which can quickly absorb small impacts. When the impact increases, the stiffness increases to prevent excessive compression and effectively cope with impacts of different degrees.

[0026] The inspection port 5 has positioning grooves 6 at both ends, and a limit slot 7 is provided on the inner side of the positioning groove 6. The inspection port 5 has a top plate 8 on the inner side, and mounting bases 9 are connected to both ends of the top plate 8. A two-way screw 10 is rotatably connected inside the mounting base 9. Two threaded connecting blocks 11 are threadedly connected to the outer wall of the two-way screw 10. Limiting blocks 12 are connected to the outer wall of the two threaded connecting blocks 11. A guide rod 13 is connected inside the mounting base 9.

[0027] It should be noted that the locomotive spring damping buffer device is a device that stores energy through the elastic deformation of the spring when the locomotive encounters an impact, and then buffers the impact by dissipating the energy through the damper.

[0028] Preferably, the mounting base 9 can be embedded inside the positioning groove 6, and the positioning groove 6 is connected to the inspection port 5. The end of the limiting plug 12 away from the threaded connecting block 11 is adapted to the size of the limiting slot 7. The outer wall of the bidirectional screw 10 is connected to the first bevel tooth 14. The top of the mounting base 9 has a knob 15 through it, and the through end of the knob 15 is connected to the second bevel tooth 16. The first bevel tooth 14 and the second bevel tooth 16 mesh with each other.

[0029] In practical use, the second bevel tooth 16 is rotated counterclockwise by the knob 15. The second bevel tooth 16 and the first bevel tooth 14 drive the bidirectional lead screw 10 to rotate. At this time, the two threaded connecting blocks 11 connected to the outer wall will drive the limiting plug 12 to move towards each other along the guide rod 13. One end of the limiting plug 12 will disengage from the limiting slot 7. Then, the inspection port 5 can be opened by lifting the top plate 8 by the knob 15, which makes it convenient for staff to inspect the internal hydraulic damper 2 and alloy spring 4.

[0030] Conversely, when installing the top plate 8, first insert the top plate 8 into the inspection port 5 and insert the end mounting seat 9 into the positioning groove 6. Then, rotate the second bevel tooth 16 clockwise by turning the knob 15. The second bevel tooth 16 and the first bevel tooth 14 drive the bidirectional lead screw 10 to rotate. At this time, the two threaded connecting blocks 11 connected by the outer wall will drive the limiting plug 12 to move in opposite directions along the guide rod 13. One end of the limiting plug 12 will be inserted into the limiting slot 7, thereby achieving fixation.

[0031] Preferably, the buffer head 3 has mounting grooves 17 at both ends, and a pulley 18 is rotatably connected to the inner side of the mounting groove 17. The inner wall of the buffer seat 1 has a sliding groove 19, and one side of the pulley 18 is located inside the sliding groove 19. The buffer head 3 can form a sliding connection structure with the buffer seat 1 through the mounting groove 17, the pulley 18, and the sliding groove 19.

[0032] In practical use, by installing groove 17, pulley 18 and slide 19, when the buffer head 3 is subjected to force, the alloy spring 4 stores energy through elastic deformation, and then the energy is buffered by the energy dissipation characteristics of the hydraulic damper 2. In addition, the pulley 18 will also slide along the slide 19 when the buffer head 3 is subjected to force, thereby playing a guiding role and improving the stability of the buffer head 3 when it is subjected to force.

[0033] Working principle: First, the device is firmly connected to the locomotive frame using the mounting holes and bolts at both ends of the buffer seat 1. When the buffer head 3 is under force, the energy is stored by the elastic deformation of the alloy spring 4, and then buffered by the energy dissipation characteristics of the hydraulic damper 2. The pulley 18 also slides along the slide groove 19 when the buffer head 3 is under force, thereby playing a guiding role and improving the stability of the buffer head 3 when it is under force. Then, by rotating the second bevel tooth 16 counterclockwise by the knob 15, the second bevel tooth 16 and the first bevel tooth 14 drive the bidirectional lead screw 10 to rotate. At this time, the two threaded connecting blocks 11 connected by the thread on its outer wall will drive the limit plug 12 to move towards each other along the guide rod 13, and one end of the limit plug 12 will disengage from the limit slot 7. Then, by lifting the top plate 8 by the knob 15, the inspection port 5 can be opened, which makes it convenient for the staff to inspect the internal hydraulic damper 2 and alloy spring 4.

[0034] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
