Problems solved by technology
[0003] The existing gantry crane is fixed at the working position, with large dimensions and heavy weight. It stands on the ground of the inspection warehouse during non-working hours. The space in the warehouse is relatively narrow. The existing gantry crane is bulky, which directly affects the movement in the warehouse. The running route of the maintenance equipment affects the daily maintenance function of the maintenance depot
Due to the very low frequency of bogie replacement, the existing gantry locomotives cause a waste of space resources in the maintenance garage
In addition, the supporting beam of the existing gantry locomotive is fixed, the operation is cumbersome, and the positioning accuracy is poor

The invention relates to the technical field of railway locomotive maintaining and discloses a portal frame vehicle machine. The portal frame vehicle machine comprises a travelling unit, a supportingunit, a lifting unit and a control unit. The travelling unit comprises two travelling bases arranged in a spaced manner and two travelling wheel assemblies; the two travelling wheel assemblies are correspondingly installed at the bottoms of the different travelling bases; each travelling wheel assembly comprises a driving travelling wheel, a driven travelling wheel and a travelling driving device,and the driving travelling wheels are connected with the travelling driving devices; the supporting unit is erected and installed on the two travelling bases; the lifting unit is installed on the supporting unit in a height adjustable manner; and the controller unit is electrically connected with the travelling driving devices and the lifting unit. The portal frame vehicle machine is convenient to transfer, can be transferred to an idle area without affecting daily maintaining operation of a maintaining library in the non-work period, the travelling route of other movable maintaining devicesin the library is not affected, the space utilizing rate in the library is increased, and the maintaining efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of railway locomotive maintenance, in particular to a gantry locomotive. Background technique [0002] When replacing a single bogie of a high-speed rail EMU in the maintenance depot of the EMU, a gantry machine is used to support the body of the high-speed rail EMU, and at the same time provide a channel for the bogie to be removed. [0003] The existing gantry crane is fixed at the working position, with large dimensions and heavy weight. It stands on the ground of the inspection warehouse during non-working hours. The space in the warehouse is relatively narrow. The existing gantry crane is bulky, which directly affects the movement in the warehouse. The walking route of the maintenance equipment affects the daily maintenance function of the maintenance depot. Due to the very low frequency of bogie replacement, the existing gantry locomotives cause a waste of space resources in the maintenance garage. I...
