The working process of the track maintenance device comprises the following steps: the first and second bases 200 and 201 are respectively seated on the front and rear sides of the deformed rail 100, and the adjustment rod 120 is sequentially screwed into the first and second clamping plates 10 and 11, and the distance between the first and second clamping plates 10 and 11 is ensured to pass through the rail head 1000. Then, the grabbing structure 101 of the first clamping plate 10 and the grabbing structure 101 of the second clamping plate 11 are placed at the rail waist 1001, meanwhile, the first clamping plate 10 and the second clamping plate 11 are kept in an upright state, the jacking connecting portion 14 is sequentially arranged in the sliding opening 13 of the first clamping plate 10 and the sliding opening 13 of the second clamping plate 11 in a penetrating mode, then the handle 1202 is manually held to rotate the adjusting rod 120, so that the first clamping plate 10 and the second clamping plate 11 move towards each other until the first clamping plate 10 and the second clamping plate 11 clamp the track 100. The two retaining members 121 are screwed in from both ends of the adjustment rod 120 until the two retaining members 121 abut against the side surfaces of the first clamping plate 10 and the side surfaces of the second clamping plate 11, respectively. The stopper pin 1210 is inserted into the appropriately positioned stopper hole 1211. The lifting driving member 21 (here, a hydraulic jack is exemplified) is arranged on the connecting plate 203 and is positioned below the lifting connecting portion 14, the lifting driving member 21 is operated, a plunger of the lifting driving member 21 is lifted to prop up the lifting connecting portion 14 to lift up, the lifting connecting portion 14 simultaneously drives the first clamping plate 10 and the second clamping plate 11 to lift up, the first clamping plate 10 and the second clamping plate 11 clamp the track 100 to lift up, and therefore the purpose of lifting up the track 100 is achieved, and the track 100 deformed downwards is reset. After the lifting of the track 100 is completed, the lifting driving piece 21 is restored to the non-working state, and then the track 100 maintenance device can be moved out of the track 100, so that the device is convenient and quick.

The track maintenance device disclosed by the utility model is light in overall design and convenient to move, can be applied to a track maintenance site, reduces the excavation amount of a cement coating, saves manpower and material resources, improves the maintenance efficiency, ensures that track equipment can be quickly recovered for production, and creates more effects.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
