Problems solved by technology
[0004] In the prior art, when lifting the whole vehicle, the chain needs to be installed every time, which is time-consuming and labor-intensive
The above-mentioned chain-type overall lifting device and structure, due to the characteristics of its own structure, when the locomotive stays on a curve, there is a certain deflection angle between the car body and the bogie, and there is a possibility that the chain will be stuck and difficult to install.

Embodiment
[0046] The locomotive and bogie integral hoisting device of the present invention, through the suspender 6 installed under the center pin 1, lifts the lifting backing plate 5 on the frame, to realize the hoisting and connection of the locomotive and the bogie.
[0047] Such as figure 2 As shown, the bottom of the central pin 1 is equipped with a suspender 6, and the suspender 6 has a "T"-shaped structure, and the central pin 1 and the suspender 6 are connected through the pin 4. When the locomotive is assembled, the boom 6 needs to be connected to the center pin 1 through the pin 4 first, and then the force transmission seat 3 is pressed into the surface of the center pin 1, and the force transmission seat can transmit the force to the longitudinal baffle 2 And transverse baffle 8. After the above assembly is completed, the car body, center pin 1 and boom 6 are integrally completed and assembled on the bogie;

The invention discloses a device for integrally hoisting a locomotive and a bogie and a hoisting method.The device comprises a hoisting rod, the hoisting rod comprises a first connecting part, a hoisting rod body and a second connecting part which are sequentially connected from top to bottom, and the first connecting part is used for being connected with the lower end of a center pin of the locomotive; the second connecting part is connected to a bogie frame below the center pin through a connecting assembly. According to the device for integrally hoisting the locomotive and the bogie and the hoisting method, the device is provided when the locomotive runs, is integrated in the locomotive, does not need additional operation when the whole locomotive is hoisted, can be used in the locomotive pulled by a center pin, is mounted at the lower part of the center pin, and realizes connection and hoisting of the locomotive and the bogie through the hoisting rod; the structure is simple, installation is convenient and quality is reliable.
Description
technical field [0001] The invention relates to the technical field of locomotive production, in particular to a device and a hoisting method for integral hoisting of locomotives and bogies. Background technique [0002] An integral hoisting device is set between the locomotive and the bogie to realize the hoisting of the whole locomotive during the production, assembly, maintenance, shipment and delivery of the locomotive. The overall lifting structure needs to ensure reliable connection between the car body and the bogie when the whole vehicle is lifted, and the lifting position needs to ensure that the weight is evenly distributed. According to the structural forms of different locomotives, a suitable overall lifting structure is set up to make it more convenient and reasonable, improve reliability and save costs. [0003] In the prior art, locomotive and bogie integral hoisting device, such as figure 1 As shown in Fig. 1, by setting lifting seats on the bogie frame sid...
