Problems solved by technology

[0004] At present, the technological bogies used on the curved track are mainly transformed from freight car bogies. The specific transformation method is: a bolster is set on the core plate of the freight car bogie, and the bolster can carry the running of the car body. The bogie has the following defects: the main frame is a casting, the welding performance is poor, and there are great hidden dangers in terms of safety

Embodiment Construction

[0023] Describe the present invention in detail below in conjunction with accompanying drawing and embodiment

[0024] A process bogie for maintenance, see attached figure 1 To attach Figure 4 , in the figure: track 101, intermediate frame 102, recess 103, wheel 2, shock absorbing device 3, bolster 4, lower core plate 5, ring groove 501, upper core plate 6, elastic side bearing 7, connector 801, spring 802, mandrel 803, sleeve rod 804, bent plate 901, baffle plate 902, blind hole 10, support base 11, stopper 1101, platform 1102, pin shaft 1103, positioning pin 1104, tubular support body 1105.

[0025] In this embodiment, the main frame is formed by connecting two parallel rails 101 through an intermediate frame 102; each rail 101 is provided with a recess 103, and the bolster 4 is supported by the intermediate frame 102 and located above the recess 103.

[0026] The track 101 of the main frame is equipped with wheels 2 through the damping device 3, the main frame ...

Abstract

The invention relates to a device for locomotive maintenance, in particular to a technical bogie for maintenance, which comprises a main frame, wheels and a swing bolster, wherein the wheels are mounted on the main frame through damping devices; a lower core plate and elastic side bearings are mounted on the main frame; an upper core plate is mounted on the swing bolster and embedded in a ring groove of the lower core plate; the elastic side bearings are in contact with the lower surface of the swing bolster. Compared with the prior art, the technical bogie for maintenance has the advantages that the damping devices and the elastic side bearings can offset impact generated when the bogie bears a vehicle body, and the main frame can achieve the purpose of safely bearing the vehicle body eventually through tracks with small curvature radiuses.

Description

technical field [0001] The invention relates to a device for locomotive maintenance, in particular to a technological bogie for maintenance. Background technique [0002] When the locomotive is undergoing overhaul, the safe operation of the car body after separation from the bogie is a very important part. If the car body cannot run stably, it will directly threaten the safety of the maintenance personnel and the integrity of the car body. [0003] At this stage, most of the new bases use straight-line track and moving car devices, and the track has good operating conditions. The bogies of the original factory can meet the car body transfer operations, but the existing vehicle factory, the old maintenance section and some newly-built factories There are often curved sections of track in and around the section maintenance depot, and the gauge of the track and the height difference between the inner and outer tracks are relatively large. [0004] At present, the technological...
