Abstract
An opening-closing unit for the front end cover of high-speed train features that said front end cover is divided into left and right halves fixed respectively to separatedly moving mechanism, and the symmetrical left and right opening-closing methaniscs are installed inside the front end cover.
Description
The present invention relates to railway locomotive, particularly high speed train or have that streamlined contour train train head lid is opened, closed isolated plant.
The effect of train train head lid is, not only will guarantee aerodynamic performance of train, and will guarantee that train connects with other locomotives easily and hang, and guarantees that train passes through curve smoothly satisfying under the condition of vehicle gauge of the locomotive.Existing high speed train or streamlined contour train and external part high speed train all do not adopt the end cap switching mechanism, and its train head lid is the integral demounting formula.Because the end cap oad is big, and out-of-shape, dismounting, install and transportation all difficult, bring great inconvenience for the shunting of train, maintenance and settlement of accident.Because the restriction of vehicle gauge of the locomotive, the end cap after the unlatching can only place the inside of head construction; The inner space of excuse bilge construction is narrow and small and irregular again, this limited and in the fitfull space according to selected end cap running orbit realize the switching campaign of end cap, reliable lock when guaranteeing that end cap is closed, the while does not move interference with other structures of head just becomes an end cap switching mechanism design-calculated difficult problem.
At present external more later-model high-speed train head end cap has adopted the design plan of switching mechanism, but its privacy degrees is very high, there is no report about the structural principle of end cap switching mechanism and scheme drawing etc., and it is also never open with this type of data to manufacture and design unit.
The objective of the invention is:
Overcome the shortcoming of integral demounting formula end cap, develop a kind of need not be with the high speed train or the stream line pattern external form opening and shutting end shield on head of railroad train special mechanism of end cap integral demounting, this mechanism can guarantee the aerodynamic configuration of train when it is closed, and end cap is placed within the head construction when opening, can guarantee that high speed train or streamlined contour train and hauling engine normally connect extension.The present invention is for achieving the above object, and the technical scheme of employing is:
About train head lid is divided into along the vertical plane of symmetry of car body 2, but about being separately fixed in the mechanism of 2 self-movements; Symmetrical two groups of switching mechanisms are installed in train head lid.
Switching mechanism partly is made up of end cap 1, end cap anchor fitting 2, portable plate (3,4), fixing plate device (5,6), slide way mechanism (7,8,9), rocking bar 10, support 11, pneumatic actuating device (12,13), manual unit 14 etc.End cap 1 is fixed on by anchor fitting 2 on the portable plate 3 that guidepost 4 is housed, and guidepost 4 can slide in the sleeve on being fixed in adapter plate 56; Portable plate 3 is hinged with connecting rod 7, and connecting rod 7 is hinged with loose slot 8, and loose slot 8 is hinged with hold down groove 9, and hold down groove 9 is affixed with adapter plate 5, and adapter plate 5 is hinged with rocking bar 10, and rocking bar 10 is hinged with mount pad 11.Mount pad 11 is fixed on the under-carriage.Cylinder 12 is fixed on the underframe, and push rod 13 is connected with cylinder piston rod, and the roller on the push rod 13 slides in the groove of hold down groove and loose slot.Manual unit is made up of push rod 13 and hand lever 14.
The present invention compared with the prior art, its advantage and good effect show as:
Solved the very inconvenient problem of installation, dismounting and transportation of integral type end cap, both can guarantee the aerodynamic configuration of streamlined train or high speed train and normally connect extension, brought great convenience for again the operation management of train and utilization maintenance with hauling engine.
Be further described below in conjunction with accompanying drawing:
Fig. 1 is the present invention's switching mechanism scheme drawing of (closed position) under the end cap closure state.
Fig. 2 is the present invention's switching mechanism scheme drawing of (translational shifting) under end cap translation state.
Fig. 3 is the present invention's switching mechanism scheme drawing of (standard-sized sheet position) under the end cap full-gear.
The end cap motion is made up of translation and plane motion two parts.Opening process is: behind the cylinder piston rod shipper pole moving be under the closure state end cap 1 backward translation one segment distance to translational shifting; Shipper pole moved end, piston rod continuation back lid 1 is opened laterally, and end cap 1 bounces back to the standard-sized sheet position simultaneously, can guarantee that high speed train or streamlined contour train and hauling engine safety connect extension this moment.Closing course and opening process reversed in order.No matter whether pneumatic system breaks down, and mechanism all can be locked with end cap, and can utilize manual unit with end cap unlatching, closed, release or locked.
Accompanying drawing has also been described working condition of the present invention:
1. end cap translation
See Fig. 1, Fig. 2, move behind the piston rod and move after making push rod 13, driving loose slot 8 rotates, when rotating, moves behind the drivening rod 7 loose slot 8, after driving portable plate 3, moves by connecting rod 7, end cap 1 moves to translational shifting along car body after vertically, this moment loose slot 8 runner rear end medial surface and the inboard coplane of the runner rear end of hold down groove 9, end cap and head configuration medial surface maintenance certain clearance.Above process is the translation process of end cap when opening, and the translation process when end cap is closed is opposite with said process.
2. end cap standard-sized sheet
See Fig. 2, Fig. 3, move after the moving push rod 13 of shipper pole continues behind the piston rod, the push rod roller moves in the chute of hold down groove 9 and loose slot 8, the double rocker mechanism motion that drive is made of adapter plate 5, rocking bar 10, make end cap 1 make plane motion along projected path, in the time of can guaranteeing end cap 1 motion and each parts of locomotive head do not move interference.End cap 1 closing course is opposite with said process.
3. the end cap closed position is locked
See Fig. 1, when end cap 1 was in closed position, cylinder piston rod all stretched out, and the mechanism top that loose slot 8 and connecting rod 7 constitute is also pinned to the dead point, and the cylinder back cavity keep-ups pressure at this moment.Even pneumatic system breaks down at this moment, when cavity pressure is zero behind the cylinder, mechanism is pinned because of the piston rod present position, piston rod itself also is lockable simultaneously, and locomotive vibration can not make its release, can guarantee that end cap 1 can self-opening.
4. end cap closed position release
See Fig. 1, Fig. 2, move behind the cylinder piston rod when being in closed position end cap 1 and carrying out release, move after driving cylinder push-rod 13, loose slot 8 is rotated make the mechanism that constitutes by loose slot 8 and connecting rod 7 break away from the dead point, thereby make mechanism's release.
5. hand gear
See Fig. 1, Fig. 2, mechanism adopts when manual, hand lever 14 is inserted and it is moving to cylinder one thruster, moves after driving push rod 13, with the switching mechanism release; Continue to promote hand lever 15, it is follow-up to drive push rod 13 continuation, realizes end cap 1 translation backward.Translation and process that mechanism is locked are opposite with said process forward to adopt hand gear to realize end cap 1.
