[0045] The present utility model will be further described below in conjunction with the drawings.

[0046] Embodiment 1

[0047] As Figures 1 to 6 shown, the present utility model provides a locomotive shock absorber tilting tool. The locomotive shock absorber tilting tool includes a main frame 10, a lifting mechanism 20 and a driving mechanism 30. The lifting mechanism 20 is used to tilt the shock absorber; the driving mechanism 30 is arranged on the main frame 10, the driving mechanism 30 is connected to the lifting mechanism 20, and the driving mechanism 30 can drive the lifting mechanism 20 to lift and lower along the first direction; the locomotive shock absorber tilting tool is configured such that the lifting mechanism 20 can partially extend into the bottom gap of the shock absorber, and the driving mechanism 30 can lift the lifting mechanism 20 along the first direction, so that the lifting mechanism 20 tilts the shock absorber.

[0048] In the above setting, the lifting mechanism 20 and the driving mechanism 30 are integrally arranged in the locomotive shock absorber tilting tool. The driving mechanism 30 is used to drive the lifting mechanism 20 to lift the shock absorber, so as to realize the tilting of the shock absorber. This tilting method uses the driving mechanism 30 to provide power, and can replace the method of prying the pry bar by hand in the prior art, thus avoiding the problems of labor consumption and low tilting efficiency caused by this method. Thereby saving on-site labor and improving the tilting efficiency at the same time.

[0049] Specifically, as Figures 1 to 6 shown, in one embodiment, the main frame 10 includes a support frame 11, a support plate 12 and a cover plate 13. Among them, the support plate 12 is arranged at the bottom of the support frame 11; the cover plate 13 covers one end of the support frame 11; the support plate 12 is used to increase the contact area between the support frame 11 and the ground, the driving mechanism 30 is arranged in the cavity formed by the cover plate 13 and the support frame 11, and a part of the lifting mechanism 20 extends out of the cavity, and the part of the lifting mechanism 20 extending out of the cavity can extend into the bottom gap of the shock absorber.

[0050] In the above setting, the support plate 12 increases the contact area between the support frame 11 and the ground, so as to ensure that the main frame 10 can be stably placed on the ground and is convenient for fixing. The cavity formed by the cover plate 13 and the support frame 11 serves as a protection structure, which can protect the driving mechanism 30 arranged therein. Avoid the driving mechanism 30 being damaged by the impact of external objects.

[0051] Specifically, as Figures 1 to 6 shown, in one embodiment, the lifting mechanism 20 includes a connecting plate 21 and a lifting component 22. Among them, one end of the connecting plate 21 is connected to the driving mechanism 30; the lifting component 22 is arranged on the connecting plate 21, and the lifting component 22 can extend into the bottom gap of the shock absorber to lift the lifting mechanism 20.

[0052] In the above setting, setting the connecting plate 21 can strengthen the connection strength between the lifting component 22 and the driving mechanism 30. Thus, it is ensured that the locomotive shock absorber lifting tool can work stably and reliably.

[0053] Specifically, as Figures 1 to 6 shown, in one embodiment, the lifting component 22 includes at least one support column 221. One end of at least one support column 221 is connected to the connecting plate 21 and can extend into the bottom gap of the shock absorber.

[0054] Specifically, as Figures 1 to 6 shown, in one embodiment, the lifting component 22 includes two support columns 221. One end of the two support columns 221 is connected to the connecting plate 21 and can extend into the bottom gap of the shock absorber.

[0055] In the above setting, multiple support columns 221 are provided. The multiple support columns 221 can simultaneously extend into the bottom gap of the shock absorber to lift the shock absorber, thus avoiding the problem of insufficient support strength of a single support column 221. Thus, it is ensured that the locomotive shock absorber lifting tool can smoothly lift the shock absorber.

[0056] Of course, the specific number of the support columns 221 can be set according to the actual weight of the shock absorber. For example, the number of the support columns 221 can be set to three or more.

[0057] Specifically, as Figures 1 to 6 shown, in one embodiment, the end of the support column 221 away from the connecting plate 21 is provided with a conical structure. In this way, one end of the support column 221 has a guiding function, so that the support column 221 can smoothly extend into the gap of the shock absorber. Thus, the convenience of its use is improved.

[0058] Specifically, as Figures 1 to 6 shown, in one embodiment, the driving mechanism 30 includes at least one rodless cylinder 31 and a connecting block 32. At least one rodless cylinder 31 extends along the first direction and is arranged in the main body frame 10; the connecting block 32 is connected to the sliding part of at least one rodless cylinder 31; the lifting mechanism 20 is fixed on the connecting block 32.

[0059] In the above setting, the rodless cylinder 31 is used as the driving member to drive the lifting mechanism 20 to move up and down, thereby realizing the lifting function of the locomotive shock absorber lifting tool.

[0060] It should be noted that the rodless cylinder 31 has a compact structure, which is convenient for reducing the overall volume of the locomotive shock absorber lifting tool. Thus, it meets the requirements of its lightweight setting, and further improves the convenience of its use.

[0061] Specifically, as Figures 1 to 6 shown, in one embodiment, the driving mechanism 30 includes two rodless cylinders 31. The two rodless cylinders 31 are arranged at intervals along the second direction. A connecting block 32 is arranged on the sliding part of each rodless cylinder 31. The two rodless cylinders 31 drive the lifting mechanism 20 simultaneously, which improves the moving stability of the lifting mechanism 20.

[0062] It should be noted that the main body frame: is made of durable metal materials, with appropriate strength and rigidity to withstand the force when prying up the locomotive shock absorber. The lifting mechanism: two metal shafts (support shafts) in the middle of the main body frame, the back of which is connected to the piston slide of the rodless cylinder, and the other end is the prying point for applying force to lift the shock absorber. The power device is two rodless cylinders, the two ends of the cylinders are fixed on the main body frame, the piston slide is connected with the lifting mechanism, and power is provided by the air compressor system to improve the prying efficiency. The fixing mechanism (support plate): a device located at the bottom of the main body frame for fixing the shock absorber lifting tool to ensure that the shock absorber remains stable during the prying process.

[0063] The method of this locomotive shock absorber lifting tool is as follows:

[0064] Step 1, insert the lifting mechanism into the gaps at both ends of the shock absorber to ensure its firm connection.

[0065] Step 2, make the fixing mechanism in close contact with the locomotive axle to ensure its stability during the prying process.

[0066] Step 3, start the pneumatic air compressor to provide power for the rodless cylinder, generate an upward force, and gradually lift the shock absorber from its fixed position.

[0067] The design of this locomotive shock absorber lifting tool takes into account portability, ease of operation and stability, making the work of replacing and repairing locomotive shock absorbers efficient and safe. Through the present invention, the operation difficulty can be reduced, the labor cost can be reduced, and the efficiency and quality of locomotive maintenance can be improved.

[0068] It should be noted that the locomotive shock absorber lifting tool in this embodiment has the following characteristics:

[0069] 1. Portability: Compared with traditional mechanical pry bar tools, this locomotive shock absorber prying tool is small in size and light in weight, making it easy to carry and operate. Maintenance personnel can conveniently carry this tool to the maintenance site without additional transportation equipment.

[0070] 2. Simple operation: This tool is simply designed and can be operated by one person to pry up the shock absorber. The operation process is more intuitive, without the need for multiple people to cooperate and complex operation steps, reducing the operation difficulty and training cost.

[0071] 3. Stability: A fixing device is used to fix the shock absorber to ensure that the shock absorber remains stable during the prying process. The design of the shock absorber fixing device makes the prying process more stable and controllable, reducing the risk of damage to the shock absorber.

[0072] 4. High efficiency: By connecting an air compression device, it provides strong power and efficiency, making it easier and more efficient to pry up the shock absorber. The speed and efficiency of shock absorber replacement and maintenance are greatly improved, saving time and human resources.

[0073] 5. Cost savings: It reduces the labor costs required for multiple people to cooperate and complex operations. At the same time, the stable prying of the shock absorber can reduce the risk of damage, reduce the repair and replacement costs, and increase the service life.

[0074] In summary, the advantages of this locomotive shock absorber prying tool, such as portability, simple operation, stability, high efficiency, and cost savings, make the replacement and maintenance of locomotive shock absorbers more convenient, fast, and safe, improving the repair efficiency and quality.
