Description
Technical Field
The utility model relates to a railway vehicle body structure, in particular to a structure for quickly installing and replacing a front windshield of a motor train unit.
Background
The connection structure of the front windshield and the train body of the motor train unit has the sealing performance requirement, so that the connection is mostly carried out by adopting the sealant, and the sealant can meet the connection strength requirement and can also meet the sealing performance requirement after being cured.
According to the practical application condition of the high-speed motor train unit, glass is used as a composite material and is limited by the attributes of the glass, the glass is inevitably subjected to the occurrence of faults such as cracking and the like when encountering foreign matter high-speed impact, the glass is inevitably replaced, original position sealant is required to be removed in the changing process, the sealant is coated on the original basis, the replacement sealant is solidified, different time periods are provided according to different brands, and therefore the motor train unit needs to be reserved for a long time when the glass is replaced, and the actual application requirement is not met.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a structure capable of meeting the requirement of quickly replacing a windshield, reducing glass replacement time and improving the utilization rate of a motor train unit.
In order to achieve the purpose, the utility model provides a motor train unit front windshield quick mounting and replacing structure which comprises a transition frame, a glass frame and a glass structure, wherein the glass frame and the glass structure are bonded together into a whole through a sealant, the transition frame is of a square hollow section structure, a mounting platform is arranged on the periphery of the transition frame, a plurality of mounting holes for connecting bolts with a train body and a plurality of thread grooves for connecting the bolts with the glass frame are formed in the outer edge of the mounting platform, a groove is formed in the inner edge of the mounting platform, a sealing rubber strip is mounted in the groove, and mounting holes for connecting the bolts are formed in the positions, corresponding to the thread grooves in the transition frame, of the glass frame.
Further, the length of the groove is 27mm, and the depth of the groove is 7.5 mm.
Further, the thickness of the transition frame is 16 mm.
Furthermore, a sealant is coated between the transition frame and the vehicle body.
The utility model designs a windshield structure consisting of a transition frame, the transition frame structure is connected with a vehicle body through a sealing adhesive and a bolt structure, only the sealing adhesive on the periphery of the glass frame needs to be removed when the glass is replaced, the glass frame and the transition frame are separated, the transition frame and the vehicle body are connected without separation, and the region for removing the sealing adhesive when the change is carried out is reduced, so that the curing time of newly applied sealing adhesive is reduced, and the fault repair time of a motor train unit is shortened.

fig. 4 is a schematic view of the connection of the bezel to the transition frame.
In the figure: 1-glass structure; 2-a glass frame; 3-a transition frame; 4-sealing adhesive tape; 5-sealing glue; 6, mounting a platform; 7-a groove; 8-mounting holes; 9-thread groove; 10-vehicle body.
Detailed Description
The glass structure 1 in the prior art is bonded with the glass frame 2 through the sealant 5 to form a whole, and the glass frame 2 is connected with the vehicle body 10 through the sealant 5, so that the whole replacement is not convenient.
Referring to fig. 1 to 4, utility model a front windshield structure with transition frame, original glass structure 1 is unchangeable, does adaptability optimization with glass frame structure 2, and glass structure 1 bonds as a whole through sealed glue 5 and glass frame 2 together, and transition frame 3 and glass frame 2 pass through bolted connection, in order to guarantee sealing performance between glass frame 2 and the transition frame 3 simultaneously, increases the 4 structures of sealing adhesive tape between two intermediate structure.
The transition frame 3 be square hollow section structure, the thickness of transition frame 3 is 16mm, transition frame 3 is the aluminum alloy material, the material keeps unanimous with glass frame 2, the appearance shape keeps unanimous with glass structure 1, 3 peripheries of transition frame be equipped with mounting platform 6, the outside edge of mounting platform 6 is equipped with the mounting hole 8 of a plurality of and automobile body 10 connecting bolt and the thread groove 9 of a plurality of and glass frame 2 connecting bolt, the inboard edge of mounting platform 6 is opened has length to be 27mm, the degree of depth is 7.5 mm's recess 7, installation joint strip 4 in the recess 7, glass frame 2 and transition frame 3 on the corresponding position of thread groove 9 be equipped with connecting bolt's mounting hole 8.
When the glass frame is installed, the transition frame 3 and the glass frame 2 are connected with the vehicle body 10 as a whole, the periphery is sealed by the sealant 5, when a fault occurs, only the bolt between the transition frame 3 and the glass frame 2 needs to be removed, and the sealant 5 at the side part of the glass frame 2 is removed to complete replacement.
A windshield structure formed by a transition frame 3 is designed, the transition frame 3 is connected with a vehicle body 10 through a sealant 5 and a bolt structure, the transition frame 3 is added, so that the transition frame 3 and the glass frame 2 are only required to be separated when the front windshield structure is replaced, the sealant removing area is reduced during the replacement, and the curing time of newly applied sealant is shortened.
