The application is described below with reference to specific embodiments in conjunction with the following drawings:
the present application provides a floor maintenance device 1000 for a railway gondola, as shown in fig. 1 to 8, the floor maintenance device 1000 for a railway gondola of the present embodiment includes:
a moving assembly 100 including a frame 110 and a moving wheel group 120 disposed under the frame 110;
the jacking assembly 200 comprises a jacking piece 210 arranged on the frame 110 and an adjusting piece 220 arranged on the jacking piece 210 in a liftable way; the adjuster 220 is used to level the base plate 240;
and the driving assembly 300 is arranged on the frame 110 and is used for driving the adjusting part 220 to lift relative to the jacking part 210.
The floor maintenance device 1000 of the railway gondola car has a simple structure, the floor maintenance device 1000 of the railway gondola car can be moved to the position below the floor of the gondola car to directly adjust and maintain the bottom plate 240 through the moving assembly 100, the moving assembly 100 does not need to be a rail, can be moved in any direction, and is wide in application places; when the floor of the railway gondola car is moved to a target position below the floor, the driving assembly 300 drives the adjusting piece 220 of the jacking assembly 200 to ascend, so that the adjusting piece 220 is jacked below the floor to detect and level the flatness of the bottom plate 240, the floor of the railway gondola car is prevented from being overhauled by using a special floor adjusting station, the requirement of adjusting and repairing the floor of the gondola car at different stations is met, and the railway gondola car floor has the advantages of flexible overhauling operation and simplicity and convenience in operation.
In the related technology, the railway open wagon is repaired by taking a rail flat wagon as an operation platform, and the rail flat wagon is installed on a fixed rail. After the railway open wagon is hoisted into the floor adjusting and repairing platform, the adjusting and repairing device is aligned to the position needing to be adjusted and repaired through the movement of the rail flat wagon on the rail and the transverse movement of the adjusting and repairing device on the flat wagon, and the adjusting and repairing device is started to adjust and repair the floor of the railway open wagon. Because the railway open wagon needs to be hoisted to the floor adjusting and repairing station provided with the fixed track, the existing adjusting and repairing device can only meet the requirement of adjusting and repairing the floor of the floor adjusting and repairing station fixed on the overhauling production line. When other maintenance stations appear again and need to repair the floor, because of unable adjusting and repairing, need hoist the vehicle again and transport to floor adjustment and repair station and carry out the adjustment and repair of floor, seriously influence production efficiency. In addition, in a small-batch overhaul operation place, the arrangement of a special floor adjusting and repairing station is not suitable in both economic aspects and use efficiency.
In this embodiment, a floor maintenance device 1000 for a railway gondola car is provided, which is capable of moving freely by setting a moving assembly 100 to separate from the limitation of a track, so that the floor maintenance device 1000 for a railway gondola car of the present application can realize quick maintenance of the floor without a fixed floor maintenance platform or a temporary working place.
In this embodiment, as shown in fig. 1, the moving wheel set 120 may include a plurality of universal wheels, and the universal wheels are disposed under the frame 110 to support the frame 110 and enable the frame 110 to move in any direction under the action of the universal wheels, so that the frame 110, the jacking assembly 200 and the driving assembly 300 disposed on the frame 110 can move at will, the flexibility of the floor maintenance device 1000 for the gondola car is improved, the floor maintenance requirements of the gondola car in different scenes are met, and the maintenance efficiency of the floor of the gondola car is improved.
Further preferably, the movable wheel set 120 is provided with a braking structure, so that when the railway gondola car floor repair device 1000 does not need to be moved or perform repair work, the railway gondola car floor repair device 1000 can be fixed at a predetermined position by the braking structure on the movable wheel set 120, and is prevented from being moved freely.
In this embodiment, as shown in fig. 1, the lifting range of the adjusting member 220 relative to the lifting member 210 is 400mm. Within the lifting range, the railway gondola car floor maintenance device 1000 can be conveniently moved under the railway gondola car underframe 2000 without restriction, and the adjusting member 220 can be pressed against the railway gondola car floor to be leveled after being lifted.
In the following embodiments of the present application, the maintenance process of the floor maintenance device 1000 of the railway gondola car of the present application is exemplified by hoisting the underframe 2000 of the railway gondola car to a certain position.
