Embodiment 1

[0044] Embodiment 1. The present invention is a rail transit vehicle maintenance and overhaul device. The present invention is aimed at the maintenance and repair of small rail transit vehicles in cities. For small rail transit vehicles in cities, it includes a locomotive 1, and the locomotive 1 The rear end is connected with a car body 2, and the car body 2 includes a bottom plate 3 fixedly connected to the upper end of the chassis, see Figure 4 , the vehicle head 1 and the vehicle body 2 are connected via the storage table 4, please refer to figure 2 , the upper end of the storage table 4 is fixed with a support column 5 along the vertical direction, and a lifting column 6 is threaded in the support column 5 along the vertical direction, so that the lifting column 6 moves along the vertical direction when rotating, and the lifting column 6 The upper end of the column 6 is rotatably connected with the hanging plate 7 extending to the upper end of the bottom plate 3. When th...

Embodiment 2

[0051] Embodiment 2, on the basis of Embodiment 1, in order to make the lifting column 6 complete the lifting better, please refer to Figure 6 , Figure 9 and Figure 11 , Figure 12 , the drive connection device 10 includes a first gear 11 arranged in rotation on the upper end of the support column 5, the first gear 11 is threadedly engaged with the lifting column 6, and the first gear 11 is in rotation with the storage table 4, because when the second When a gear 11 rotates, it is limited and cannot move in the vertical direction, and then the lifting column 6 is rotated. Since the lifting column 6 and the support column 5 are threadedly arranged, the lifting column 6 is moved in the vertical direction when rotating. , when the first gear 11 rotates, it drives the lifting column 6 to rotate and move vertically. The first gear 11 is meshed with a second gear 12 that rotates with the storage table 4. The outer side of the second gear 12 is coaxially fixed There is a first ...

Embodiment 3

[0053] Embodiment 3, on the basis of Embodiment 2, in order to make the ejector rod 9 lift the vehicle to be repaired better, please refer to Figure 4 , Figure 5 and Figure 7 , Figure 8 The driving connection device 10 also includes a turbine 14 placed at the lower end of the bottom plate 3, the turbine 14 is arranged in rotation with the bottom plate 3, the turbine 14 is sleeved on the outside of the push rod 9 and is threadedly arranged with the push rod 9, so that When the worm gear 14 rotates, it drives the push rod 9 to rotate and move vertically, and the worm gear 14 is engaged with a worm screw 15 arranged in cooperation with the rotation of the bottom plate 3;

[0054] In the specific use of this embodiment, first, the vehicle is transported to the upper end of the base plate 3, and the vehicle at this time is placed on the upper end of the push rod 9, and then rotates by driving the worm 15, and then the worm gear 14 meshed with the worm 15 completes the synchro...

Abstract

The invention relates to a rail transit vehicle maintenance and overhaul device which effectively solves the problems that an existing rail transit vehicle maintenance and overhaul device is inconvenient to lift, low in working efficiency and complex in operation. According to the technical scheme, the device comprises a vehicle head, the rear end of the vehicle head is connected with a vehicle body, the vehicle body comprises a bottom plate, the vehicle head is connected with the vehicle body through a storage table, a supporting column is fixed to the upper end of the storage table in the vertical direction, and a lifting column is arranged in the supporting column in a screw-thread fit mode so that the lifting column can move in the vertical direction when rotating. An ejector rod is arranged on the bottom plate in a threaded fit and penetrating mode in the vertical direction, the ejector rod moves in the vertical direction when rotating, and the ejector rod is connected with the lifting column through a driving connecting device, so that the ejector rod and the lifting column complete synchronous lifting. A dragging rope driven by a motor is arranged in the vehicle body, and adragging hook is fixed to the front end of the dragging rope. The device is high in practicability, and the safety coefficient and the working efficiency of maintenance personnel are improved.

Description

technical field [0001] The invention relates to the technical field of rail transit vehicles, in particular to a maintenance and overhaul device for rail transit vehicles. Background technique [0002] Rail transit refers to a type of transportation means or transportation system that operating vehicles need to run on specific tracks. Common rail transit includes traditional railways, subways, light rails and trams. , defines urban rail transit as "a general term for fast and large-capacity public transportation that is usually powered by electric energy and adopts wheel-rail operation." [0003] The present invention is mainly aimed at the overhaul of small rail transit vehicles in cities. With the continuous development of the times, rail transit vehicle maintenance and overhaul devices play an important role in the process of rail transit vehicle maintenance and overhaul for urban rail transit vehicles. Function, the rail vehicle maintenance and overhaul device is an aux...
