Detailed implementation manners

[0023] The present utility model will be further described below with reference to the accompanying drawings.

[0024] As Figure 1 shown, a locomotive maintenance tooling according to an embodiment of the present utility model includes a base 1, a placement groove 2, a positioning mechanism 3 and a wheel set 4. The placement groove 2 and the positioning mechanism 3 are both arranged on the top of the base 1, and the wheel set 4 is arranged at the bottom of the base 1. The placement groove 2 includes a bottom plate 21 and a first baffle 22, a second baffle 23, a third baffle 24 and a fourth baffle 25 arranged on the bottom plate 21. As Figure 2 shown, the third baffle 24 includes a first vertical plate 241 and a first inclined plate 242 arranged on the top of the first vertical plate 241. The fourth baffle 25 includes a second vertical plate 251 and a second inclined plate 252 arranged on the top of the second vertical plate 251. The first baffle 22 is arranged opposite to the first vertical plate 241, and the second baffle 23 is arranged opposite to the second vertical plate 251. The positioning mechanism 3 is arranged close to the first baffle 22. The positioning mechanism 3 includes a lifting assembly 31, a translation assembly 32 and a positioning plate 33. The translation assembly 32 is arranged on the lifting assembly 31, and the positioning plate 33 is arranged on the translation assembly 32 to move in the horizontal direction.

[0025] The first inclined plate 242 at the top of the first vertical plate 241 and the second inclined plate 252 at the top of the second vertical plate 251 can provide a guiding function for the components to be repaired entering the placement groove 2, enabling them to fall more smoothly into the interior of the placement groove 2. The first baffle 22, the second baffle 23, the third baffle 24, and the fourth baffle 25 jointly enclose the component to be detected, preventing it from slipping out of the placement groove 2. The positioning plate 33 in the positioning mechanism 3 adjusts the position of the positioning plate 33 through the lifting assembly 31 and the translation assembly 32, thereby tightly pressing the component to be repaired in the placement groove 2, and can fix components to be repaired with different shapes and sizes. The wheel set 4 provided at the bottom of the base 1 facilitates the movement of the locomotive maintenance tooling.

[0026] As Figure 2 shown, a buffer pad 243 is provided on the surface of the first inclined plate 242. The buffer pad 243 is made of rubber or other elastic materials, which can absorb a certain degree of impact and protect the first inclined plate 242.

[0027] As Figure 1 and Figure 2 shown, first limit plates 244 are provided at both ends of the first inclined plate 242, and second limit plates 253 are provided at both ends of the second inclined plate 252. The first limit plates 244 and the second limit plates 253 can prevent the components to be repaired from slipping when placed in the placement groove 2, thus avoiding accidents.

[0028] As Figure 1 and Figure 3 shown, the lifting assembly 31 includes a first hydraulic cylinder 311 and a supporting plate 312. The first hydraulic cylinder 311 is provided on the base 1, the supporting plate 312 is provided on the first hydraulic cylinder 311, and the translation assembly 32 is provided on the supporting plate 312. The first hydraulic cylinder 311 is vertically arranged, which can make the translation assembly 32 and the positioning plate 33 rise or fall as a whole, thereby adjusting the height of the positioning plate 33, so that the positioning plate 33 can tightly press the component to be repaired at different heights.

[0029] Furthermore, the translation assembly 32 includes a fixing plate 321 and a second hydraulic cylinder 322. The second hydraulic cylinder 322 is horizontally arranged, and the fixing plate 321 and the positioning plate 33 are respectively arranged at both ends of the second hydraulic cylinder 322. The fixing plate 321 remains stationary. When the second hydraulic cylinder 322 operates, the positioning plate 33 provided on the second hydraulic cylinder 322 can move in the horizontal direction. By adjusting the position of the positioning plate 33, it can tightly press the component to be repaired in the placement groove 2, thereby achieving fixation.

[0030] As Figure 3As shown, the positioning mechanism 3 further includes a rotating table 34. The rotating table 34 includes a first connecting plate 341, a turntable 342, and a second connecting plate 343. The turntable 342 is disposed between the first connecting plate 341 and the second connecting plate 343. The first connecting plate 341 is disposed on the supporting plate 312, and the fixing plate 321 is disposed on the second connecting plate 343. When preparing to place the component to be repaired in the placement groove 2, the positioning plate 33 is turned towards the side away from the placement groove 2, so as to provide more space for the component to be repaired to be placed. After the component to be repaired is placed, the rotating table 34 then turns the positioning plate 33 towards the placement groove 2, so that the positioning plate 33 is closer to the placement groove 2, reducing the stroke of the second hydraulic cylinder 322.

[0031] As Figure 4 shown, in another embodiment, a buffer mechanism 5 is further provided inside the placement groove 2. The buffer mechanism 5 includes a first flat plate 51, a buffer member 52, and a second flat plate 53. The buffer member 52 is disposed between the first flat plate 51 and the second flat plate 53, and the first flat plate 51 is disposed on the bottom plate 21. The buffer mechanism 5 can reduce the impact generated when the component to be repaired is placed in the placement groove 2, playing a protective role for both the locomotive repair tooling and the component to be repaired.

[0032] Specifically, the buffer member 52 includes a shock absorber 521 and a spring 522. The shock absorber 521 is disposed inside the spring 522. The shock absorber 521 can provide damping, suppressing the oscillation phenomenon of the spring 522, making the spring 522 quickly stable, and avoiding the up-and-down vibration of the component to be repaired after it is placed in the placement groove 2.

[0033] Furthermore, the buffer mechanism 5 further includes a cushion plate 54 disposed on the surface of the second flat plate 53. The cushion plate 54 is laid on the surface of the second flat plate 53, playing a protective role for the second flat plate 53, and it can be conveniently replaced after the cushion plate 54 is damaged.

[0034] As Figure 2 shown, the wheel set 4 includes rollers 41, a wheel axle 42, and a support member 43. The support member 43 is disposed at the bottom of the base 1. The wheel axle 42 passes through the rollers 41 and is disposed on the support member 43. Four wheel sets 4 are provided at the bottom of the base 1, enabling the locomotive repair tooling to move smoothly.

[0035] Although the present invention has been described with reference to the preferred embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various technical features mentioned in each embodiment can be combined in any way.
