Rail vehicle bottom frame equipment mounting structure

Abstract

The invention discloses a rail vehicle bottom frame equipment mounting structure comprising a bottom frame with a hollow mold cavity, at least one first mounting hole formed in the lower surface of the bottom frame and corresponding to the hollow mold cavity and an adjusting sliding block assembly matched with the first mounting holes. The adjusting sliding block assembly comprises adjusting sliding blocks capable of being clamped into the first mounting holes and sliding in the first mounting holes but not being pulled away and fasteners enabling bottom frame equipment to abut against the lower surfaces of the adjusting sliding blocks for fastening. According to the rail vehicle bottom frame equipment mounting structure, a transitional mounting seat of complex structure and a mounting structure matched with a C-shaped groove are abandoned, the limited mounting space of the bottom frame is saved, mounting of equipment of various structural styles and sizes can be met, and certain adjusting margin is taken into consideration.

Description

technical field [0001] The invention belongs to rail vehicle technology, and in particular relates to a rail vehicle underframe equipment installation structure. Background technique [0002] The underframe of rail vehicles generally adopts hollow aluminum alloy extruded profiles, and a C-shaped groove 100 is arranged at the bottom of the underframe profile for installing equipment, see figure 1 . The installed equipment needs to be hung by means of an additional transitional mounting base 200 , the transitional mounting base 200 is connected to the C-shaped groove 100 first, and then the equipment is connected to the transitional mounting base 200 . [0003] transition mount 200 as figure 2 As shown, this part is mostly forged (a few types use welded parts), the manufacturing process is relatively complicated, and the corresponding connecting seat needs to be designed according to the structure of the transitional mounting seat on the equipment to match it.

Problems solved by technology

[0003] transition mount 200 as figure 2 As shown, this part is mostly forged (a few types use welded parts), the manufacturing process is relatively complicated, and the corresponding connecting seat needs to be designed according to the structure of the transitional mounting seat on the equipment to match it

[0004] Secondly, the space between the chassis 1 and the rail surface is small, especially for the car body with a low-floor structure, so the installation space for the equipment under the car is tight. Using the transition mount 200 will further restrict the installation space, and even cause some large equipment to be unable to install at all. Installation, the selection of equipment structure is further limited
