Description
Technical Field
[0001] The utility model relates to the field of maintenance equipment for diesel locomotive parts, in particular to a disassembly tool for a diesel locomotive elastic coupling. Background Art
[0002] The flexible coupling on a diesel locomotive is a key component in the locomotive's power transmission system. It tightly connects the crankshaft output of the diesel generator set with the rotor of the main generator, ensuring efficient and stable power transmission. In this process, the flexible coupling not only withstands enormous torque but also plays an important role in buffering and reducing vibration, effectively protecting the stability and reliability of the entire power system.
[0003] However, precisely because of its crucial role in locomotive operation, the maintenance and overhaul of flexible couplings is particularly crucial. To ensure long-term, stable operation, they must be regularly disassembled and inspected to promptly identify and address potential faults. However, this task currently faces significant challenges: the flexible coupling's large size, complex structure, and heavy weight make manual disassembly and installation extremely difficult.

[0017] Furthermore, a plurality of reinforcing ribs are provided on the top plate.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:
[0031] like Figures 1 to 4 As shown, a diesel locomotive elastic coupling removal tool includes a top plate 1, side support plates 2 symmetrically distributed about the top plate 1, a foot plate 3 and a side connecting rod 4. The left and right sides of the top plate 1 are respectively hinged to the upper ends of the side support plates 2, and the lower ends of the side support plates 2 are hinged to the upper surfaces of the foot plates 3 (the side support plates 2 are provided with grips for conveniently adjusting their positions, which are not shown in the figure). The foot plates 3 are provided with through holes (the through holes on the foot plates 3 can be fixed to the mounting holes of the elastic coupling 11 by bolts. The mounting holes are not numbered in the figure. For details, please refer to the attached manual). Figure 3As shown in ), two groups of side connecting rods 4 are symmetrically distributed on the front and rear sides of the top plate 1, and one group of side connecting rods 4 includes two symmetrically distributed side connecting rods. The upper ends of the side connecting rods 4 are hinged to the top plate 1, and the lower ends of the side connecting rods 4 are hinged to the foot plates 3. The side connecting rods 4 are arranged parallel to the side support plates 2, so that when the side support plates 2 are rotated, the foot plates 3 can always remain parallel to the top plate 1.
[0032] Further refinement of the embodiment of the present invention is as follows: Figure 4 As shown, symmetrically distributed upper side panels 10 are provided on the front and rear sides of the top plate 1, and the upper side panels 10 are hinged to the upper end of the side connecting rod 4 through a pin shaft. Lower side panels 9 are respectively provided on both sides of the foot plate 3, and the lower side panels 9 are hinged to the lower end of the side connecting rod 4 through a pin shaft.
[0033] Further refinement of the embodiment of the present invention is as follows: Figure 1 and Figure 2 As shown, a top rod 7 is installed at the lower end of the top plate 1, and a positioning sleeve 8 is sleeved on the outer side of the top rod 7;
[0034] The above embodiment is further optimized, in which a limiting ring is provided at the lower end of the push rod 7, and a stepped through hole is provided in the positioning sleeve 8. The upper end hole of the stepped through hole is a small diameter hole, and the small diameter hole slides with the push rod 7. The lower end hole of the stepped through hole is a large diameter hole, and the large diameter hole slides with the limiting ring, and the diameter of the limiting ring is larger than the diameter of the small diameter hole. This can prevent the hydraulic jack 12 from deviating from the top and damaging the top plate. The limiting ring and the stepped through hole are not shown in the figure.
[0035] Further refinement of the embodiment of the present invention is as follows: Figures 1 to 4 As shown, a plurality of reinforcing ribs 6 and lifting rings 5 are provided on the top plate 1; the reinforcing ribs 6 can enhance the structural strength of the top plate 1, and the lifting rings 5 can be used in conjunction with an overhead crane.
[0036] The workflow of this utility model:
[0037] When the elastic coupling 11 needs to be disassembled, first rotate the support plates 2 on both sides, and then adjust the horizontal position of the two foot plates 3. When the through holes on the foot plates 3 are aligned with the mounting holes on the elastic coupling 11, use bolts to connect the through holes on the foot plates 3 with the mounting holes of the elastic coupling 11.
[0038] Then, the lower end of the hydraulic jack 12 is placed on the crankshaft, and the upper end is inserted into the positioning sleeve 8 and connected to the limit ring for positioning. This can effectively prevent the hydraulic jack 12 from deviating during operation and damaging the top plate 1. The hydraulic jack 12 can then push out the elastic coupling 11. After the elastic coupling 11 is pushed out, the overhead crane is used to hook the lifting ring 5 and lift the elastic coupling 11 to a safe position.
[0039] Compared with the prior art, the present application can quickly remove the elastic coupling 11 from the crankshaft of the diesel engine when the elastic coupling 11 needs to be maintained and repaired through the efficient cooperation of the hydraulic jack 12 and the disassembly tool, which is convenient and effortless to operate and has a better use effect;
[0040] In addition, through the connection and cooperation between the top plate 1, the side support plate 2, the foot plate 3 and the side connecting rod 4, the horizontal distance between the two foot plates 3 can be adjusted by rotating the side support plate 2, and the foot plate 3 can always remain parallel to the top plate 1, thereby avoiding the device from being deformed at will during use, and thus being able to adapt to the connection of elastic couplings 11 of different models and sizes.
[0041] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
