Description
Technical Field
The utility model belongs to the technical field of rail vehicle makes, concretely relates to rail vehicle front windshield mounting structure.
Background
In a railway vehicle, a front windshield is generally arranged at the front end (cab) of the vehicle and is bonded to a glass fiber reinforced plastic hood or an aluminum alloy skin head to provide a sufficient view for a driver to drive the vehicle; the traditional front windshield structure is only glass with a certain thickness, a window frame is not arranged, and an interface between the traditional front windshield structure and a glass fiber reinforced plastic head cover or an aluminum alloy skin head cover is of an adhesive structure. Although the structure has good sealing performance, the time for mounting and dismounting is long, if the glass of a vehicle is accidentally damaged in the running process, the glass needs to be replaced quickly, the structure cannot be replaced within 1 hour or less due to the long adhesive curing period caused by cleaning and gluing of the adhesive, and the maintainability is poor.
SUMMERY OF THE UTILITY MODEL
The invention aims to solve the problem that the maintainability of a front windshield glass structure in a traditional railway vehicle is poor, and the front windshield glass structure capable of being rapidly disassembled and assembled is designed, so that the replacement and the assembly can be rapidly completed when the front windshield glass needs to be replaced in an emergency in a short time.
In order to achieve the above purpose, the technical scheme of the utility model is that:
the utility model provides a rail vehicle front windshield mounting structure which characterized in that: the automobile hood comprises an automobile hood, an outer window frame, a windshield and an inner window frame, wherein the inner window frame is fixedly connected with the automobile hood through inner frame mounting screws and sealed through inner frame sealing rubber strips; the windshield is installed between the inner window frame and the outer window frame through a glass adhesive tape and is fastened through an outer frame installation screw, and the inner window frame and the outer window frame are sealed through an outer frame sealing adhesive tape.
Furthermore, the inner side surfaces of the inner window frame and the outer window frame are provided with integrated grooves, and the windshield and the glass rubber strip are embedded in the grooves.
Furthermore, the inner frame mounting screws and the outer frame mounting screws are installed in a staggered mode.
Furthermore, the glass adhesive tape is of a concave structure and is matched with the integrated grooves in the inner window frame and the outer window frame.
Furthermore, an outer frame sealing strip is arranged between the inner window frame and the outer window frame.
Furthermore, the inner frame mounting screws for connecting the inner window frame and the vehicle head cover are countersunk screws.
The utility model discloses change the bonding structure between traditional front windshield and the hood, increase excessive window frame between glass and preceding end cover, the mounting means of window frame and preceding end cover is the screw fastening, and the adhesive tape is sealed, and glass itself is fixed in between the inside and outside window frame, and through the screw fastening, the adhesive tape is sealed. Compared with the traditional front end windshield structure in the prior railway vehicle, the front windshield structure disclosed by the invention not only can achieve the same sealing effect as the traditional structure, but also greatly improves the maintainability, so that the replacement and installation can be quickly completed in case of emergency, short time and the need of replacing the front windshield, and precious time is won for the smooth operation again after the vehicle fails.
Drawings
FIG. 1 is an exploded view of the present invention;
FIG. 2 is a schematic view of the outer window frame of the present invention;
fig. 3 is a schematic cross-sectional view of the inner window frame of the present invention.
In the figure: 1-mounting screws on the outer frame; 2-outer window frame; 3-outer frame sealing rubber strip; 4-a windshield; 5-glass adhesive tape; 6-mounting screws on the inner frame; 7-inner window frame; 8-inner frame sealing rubber strips; 9-vehicle hood.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and embodiments
As shown in fig. 1 to 3, the windshield 4 is sandwiched by the outer sash 2 and the inner sash 7 by the bead glass 5, fastened by the outer frame mounting screws 1, and sealed by the outer frame bead glass 3. The inner window frame 7 is arranged on a front end hood 9 through inner frame mounting screws 6 and is sealed through an inner frame sealing rubber strip 8, and the inner frame mounting screws and the outer frame mounting screws are arranged in a staggered mode.
When the front windshield 4 is installed, the inner window frame 7 is installed on the front end hood 9 through the inner frame installation screws 6 and sealed through the inner frame sealing rubber strips 8 with the sequence numbers, and then the outer window frame 2, the windshield 4 and the glass rubber strips 5 are fixed on the inner window frame 7 through the outer frame installation screws 1 and the outer frame sealing rubber strips 3 to complete installation.
When only the front windshield 4 is replaced, the outer frame mounting screws 1, the outer window frame 2, the glass 4, the glass rubber strips 5 and the outer frame sealing rubber strips 3 need to be detached, and the replacement of the windshield is completed after the replacement of the glass according to the repeated process of the detachment.
When the whole front windshield structure is replaced, firstly, the outer frame mounting screws 1, the outer window frame 2, the glass 4, the glass rubber strips 5 and the outer frame sealing rubber strips 3 need to be detached, then the inner frame mounting screws 6, the inner window frame 7 and the inner frame sealing rubber strips 8 are replaced by new parts, and the whole replacement of the front windshield is completed.
