The existing cab wall top plate mainly comprises a side wall plate, a side top plate, a middle top plate, a cover plate, an air return grating plate and a buckle plate. The side wall plates are positioned at the first position side and the second position side of the cab, a side window is formed in the middle of the side wall plates, and the side wall plates are fixed on a vehicle body mounting seat through bolts; the side top plates are positioned at the left and right corners of the upper side of the cab and are connected to the side wall plates and the vehicle body mounting seat through bolts; the cover plate is positioned around the windshield and the sunshade curtain and is respectively connected with the side wall plate, the side top plate and the middle top plate; the middle top plate is provided with an inspection door, is positioned at the top of the cab and is fixed on the roof mounting seat through bolts, and two sides of the middle top plate are lapped on the flanges of the side top plates; the return air grid plate is fixed on the turned edge of the middle top plate through a bolt; the pinch plate is positioned between the rear sides of the left and right wallboards and the dividing wall and is fixed on the vehicle body mounting seat through bolts.
The above structure has the following problems:
1. the middle top plate is provided with an inspection door, so that the middle top plate is easy to deform in the long-time use process and inconvenient to maintain and disassemble;
2. the buckle plate is arranged between the side wall plate and the dividing wall, and due to the reasons of vehicle body error, built-in installation precision and the like, the buckle plate is difficult to match with the wall plate and the dividing wall according to the theoretical size, so that the installation effect is influenced;
3. sunshade screen cover plate and sunshade screen formula structure as an organic whole, the installation accuracy is difficult to guarantee.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a novel EMUs cab wall roof structure dismantles easy maintenance, improves the installation accuracy, improves the driver's room air conditioner effect.
In order to realize the utility model discloses the purpose, the utility model provides a novel EMUs cab wall roof structure, overhaul cover plate, style grid tray, its characterized in that including side wall board, side roof, well roof, sunshade screen: three insertion points are arranged on the reverted grid plate, L-shaped angle irons are arranged at the positions of the partition wall of the cab, which correspond to the insertion points of the return air grid plate, and the insertion points on the reverted grid plate are sleeved in the L-shaped angle irons to finish the installation; the middle top plate and the side top plate are connected in a plugging mode; a sticky plate is arranged between the left side wall plate, the right side wall plate and the partition wall and is used for carrying out on-site vehicle research and matching according to an actual gap between the wall plates and the partition walls; sunshade screen and sunshade screen overhaul cover plate are split type structure, fix the sunshade screen earlier during the installation, and its maintenance cover plate of back installation makes both installations not restrict each other, has promoted the installation accuracy.
Furthermore, the side roof is close to on side wallboard one side is fixed in the automobile body mount pad through the bolt, is equipped with four connecting pieces near middle one side, and well roof then is equipped with four corresponding insertion points, and four insertion points of well roof overlap on the corresponding connecting piece of both sides roof, and both easy to assemble is firm reliable again, and convenient the dismantlement simultaneously need not to set up the electrical part on the inspection roof of inspection door alone.
The utility model optimally designs the wall roof of the Jingzhang high-speed rail cab, cancels the roof inspection door with the original structure, changes the connection mode of the main blocks into a full-splicing mode, and improves the convenience of installation and disassembly; the buckle plate at the rear part of the wallboard is changed into a sticky plate so as to be convenient for gap grinding and matching; the sun-shading maintenance cover plate is changed into a split structure so as to improve the installation precision.
