Description
Technical field
The present invention relates to rail vehicle technical field, in particular to a kind of windscreen of Fast Installation integrates and its installing and dismounting
Method.
Background technique
The pressure loss caused by train vehicle end resistance is predominantly vortexed, accounts for the large percentage of full vehicle resistance.For this purpose, using
Outer hood is installed at the vehicle end of train, mainly plays flexible connection, makes car body that there is good continuity.Pass through the peace of outer hood
Dress, reduces the windage and wind-dryness of train, while protecting the damper and interior windscreen of vehicle end position, while avoiding passenger when waiting
Fall into vehicle end position.
As shown in Figure 1 to Figure 3: outer hood (B) has all been applied in domestic position train vehicle end (A, C) at present, still
It is substantially using bolt fastening in mounting base, then again connect mounting base with car body, installation method is cumbersome, regular to deposit
In following problems:
A, installation bolt is more, it is desirable that is first first mounted in mounting base outer hood capsule, then again integrates assembled windscreen
It is mounted on train body headwall.
Once b, outer hood capsule fails, disassembly is complicated, time-consuming and laborious.
In consideration of it, assembly working amount can be reduced it is necessary to design a kind of windscreen structure for being easily installed and dismantling, reduce
Failure risk is assembled, assembling product efficiency and use reliability are improved.
Do not retrieved temporarily by patent retrieval with the patent literature report of same technique of the present invention, have certain pass with the present invention
The patent of system has following patents:
It is " 2014.12.18 " application No. is " CN201410796478.X ", the applying date, Publication No. " CN104608780A ", public affairs
It opens and day is " 2015.05.13 ", entitled " Motor train unit body and its split type outer hood ", applies for artificial " southern vehicle Qingdao four directions
The Chinese invention patent of rolling stock limited liability company ", a kind of Motor train unit body of the patent disclosure and its split type exogenous wind
Gear, split type outer hood are installed on the headwall of Motor train unit body, the outer hood include split settings sealing windscreen section and
Dismountable maintenance windscreen section, the maintenance windscreen section correspond to the maintenance position of the headwall.When needing to overhaul, as long as will
Maintenance windscreen section is dismantled and can be carried out, and is not necessarily to overall pulling down, can be reduced the repair time, improve efficiency.The patent is intended merely to just
In maintenance, in the local overhauling position of outer hood, the dismountable maintenance windscreen section of setting, is not to be designed as entire outer hood
The windscreen for capableing of Fast Installation disassembly is integrated, and its structure is more complex, connector is more, installation is inconvenient.
Summary of the invention
The technical problem to be solved by the present invention is in view of the deficiencies in the prior art, provide a kind of wind of Fast Installation
Gear integrates and installing/dismounting method.
In order to solve the above technical problems, the technical solution used in the present invention are as follows: a kind of windscreen of Fast Installation is integrated, packet

Usage amount and weight, reduce cost, meet the light-weighted requirement of vehicle, while also can be reduced the rigidity of windscreen capsule, be convenient for
It is deformed when windscreen capsule mutual extrusion.
Further, the auxiliary section is the card slot one being arranged on the short bottom edge of the right-angled trapezium and is arranged described
Card slot two on the long bottom edge of right-angled trapezium.This notch is simple, produces convenient for manufacture.
Further: wall ratio of the cavity far from two position of the card slot one or card slot is close to the card slot one or card
The wall thickness at two position of slot is thin.To guarantee that the root of windscreen capsule has biggish strength and stiffness, the top of windscreen capsule has
Lesser rigidity, convenient for being deformed at the top of windscreen capsule in mutual extrusion.
Further, the mating connection portion one is fixing strip, and the fixing strip is embedded into the windscreen capsule
In card slot one；The mating connection portion two is movable strip, and the activity strip is embedded into the card slot two of the windscreen capsule.
This strip structure is simple, further increases work convenient for manufacture production, reduction production cost convenient for being rapidly assembled and disassembled
Efficiency.
Further, the fastener is bolt, and the threaded hole with bolt cooperation is provided on the fixed clamping piece；Institute
State the through-hole for being provided on active clamping piece and passing through for bolt, separate one with the fixed clamping piece contact surface of the through-hole
Side is provided with the cylindricality counterbore that can accommodate bolt head, and locking pad is additionally provided between the bolt and the active clamping piece
Piece is screwed into the threaded hole after check washer and through-hole described in the screw bolt passes, by the active clamping piece and institute
It states fixed clamping piece and clamps connection.The check washer of setting can prevent bolt looseness, it is ensured that connection is reliable.
Further, the fastener is sunk screw, is provided on the fixed clamping piece and sunk screw cooperation
Threaded hole；It is provided with the through-hole passed through for sunk screw on the active clamping piece, the through-hole is separate with the fixing clamp
The side of tight part contact surface is provided with the cone shaped countersink that can accommodate sunk screw head, and the sunk screw is twisted across the through-hole
Enter in the threaded hole, the active clamping piece and the fixed clamping piece are clamped and connected.Using sunk screw, wind can be made
It is beautiful to keep off surfacing, while also reducing windage.
The invention further relates to the installing/dismounting methods that above-mentioned windscreen integrates: it is provided with fixed clamping piece on vehicle end margin,
It is provided with active clamping piece on the fixed clamping piece, by fastener by the active clamping piece and the fixed clamping piece
Connection forms clamping structure, and the windscreen capsule clamping between the active clamping piece and the fixed clamping piece will be arranged in
Tightly, to carry out the integrated installation of windscreen；Or the active clamping piece is fixed to clamp with described by unloading the fastener
Part mutually separates, and unclamps the clamping to the windscreen capsule, to carry out the integrated disassembly of windscreen.It is this method simple installation, fast
Speed improves work efficiency.
Further, installation steps are as follows:
S1: the windscreen capsule is cooperated towards the auxiliary section of car body side and the mating connection portion one of the fixed clamping piece and is connected
It connects；
S2: the active clamping piece is fitted on the windscreen capsule, by the mating connection portion two on the active clamping piece
