Detailed description of the invention
The utility model provides a kind of rail transit locomotive cab side-window, and described side window comprises 1-cross member, 2-draw-in groove one, 3-spring locating piece, 4-preloading spring, 5-side window fixed frame, 6-glass support beam, 7-glass holder profile, 8-side window glass, 9-handle, 10-side window inside casing, 11-side window housing, 12-draw-in groove two, 13-pull bar, 14-crank fixed head, 15-crank, 16-connecting rod, 17-slide rail and 18-slide block.On the floor that described side window fixed frame and cross member are all fixedly installed on drivers' cab or sidewall; Side window glass is fixedly installed in glass holder profile, and the width of the width of glass holder profile fore-and-aft direction in drivers' cab and side window fixed frame is adaptive, the height of glass holder profile is less than side window fixed frame height, and thus side window glass can slide up and down to be arranged in side window fixed frame with glass holder profile; Described glass support beam to be horizontally set in side window fixed frame and for supporting described glass holder profile and glass; The length direction of described slide rail to be arranged and slide rail is positioned at the center of the width of side window fixed frame in vertical, the width of side window fixed frame is fore-and-aft direction in drivers' cab, the bottom of slide rail is fixedly connected on cross member, and the top of slide rail is directly or indirectly fixedly connected on locomotive cab sidewall; The slide block supporting with slide rail is connected with described glass support beam; One end of described crank rod assembly is fixedly connected on side window fixed frame, and the other end is connected to support that slide block is taken side window glass and vertically moved up and down in described slide rail with slide block.
In the side window structure that the utility model provides, crank connecting rod sliding block mechanism is formed by 14-crank fixed head, 15-crank, 16-connecting rod, 17-slide rail, 18-slide block, the two ends of 17-slide rail are fixed by welding in above 1-cross member and 11-side window housing, for playing the guiding role to slide block, adjustment the stressed of side window glass is played a crucial role.15-crank and 16-connecting rod control slide block and move up and down, and ensure that side window can open and close freely.4-preloading spring is positioned, on 5-side window fixed frame, to provide pretightning force by 13-pull bar for crank connecting rod sliding block mechanism by 3-spring locating piece, guarantees that side window glass can come to a complete stop on arbitrary height.15-crank is fixed on 5-side window fixed frame by 14-crank fixed head, and such as adopts rivet interlacement between 15-crank and 14-crank fixed head, ensure that freely rotating of crank.As can be seen from crank connecting rod sliding block mechanism above, side window glass is by slider support, slide block is positioned at the center of side window glass, thus when ensureing that side window glass slides up and down, the situation of stressed bias can not be there is, avoid the side grinding that side window fixed frame is subject to glass holder profile, ensure that normal use and the durability of window frame.
Wherein, crank fixed head 14 and crank 15 are the straight plate of length 150 ~ 160mm, width 24mm and thickness 6mm, wherein crank 15 first is flexibly connected point and the distance between second is flexibly connected a little is 130mm, and the first flexible connection to put the distance between being flexibly connected a little with the 3rd be 25mm.Described connecting rod 16 is for having the sheet material at two bending angles, and the angle at bending angle is about 160 ° ~ 170 °, and the length of described connecting rod 16 is 240mm, and thickness and the width of thickness and width and crank fixed head 14 and crank 15 are consistent.
Wherein draw-in groove 1 and draw-in groove 2 12 are arranged on sustained height, the two acting in conjunction, support-side window glass when droping to lowest part for side window glass.
Preloading spring 4 shown in Fig. 1 is each one up and down, but those skilled in the art are accessible, and described spring can be one or more, such as, on vertical direction four springs arranged in parallel.One end of preloading spring 4 is fixed, and its other end stretches in the horizontal direction.Handle drives glass when sliding downward or upward, and in order to offset the downward gravity of side window glass, preloading spring 4 produces the power that acts on pull bar 13 to balance this gravity.
In the utility model, the height of side window fixed frame 5 is 1.1 ~ 1.5m, such as, be 1.2m, and width is 0.5 ~ 0.7m, such as, be 0.6m.Described side window glass 8, glass holder profile 7, side window inside casing 10 and side window housing 11 are the rounded square being dimensioned slightly smaller than 0.6m.In a kind of detailed description of the invention, the distance between the vertical height of described slide rail 17 with the base of side window housing 11 to cross member 1 is consistent.Side window inside casing 10 and side window housing 11 mainly provide support and sealing function for side window glass 8 and glass holder profile 7.
In cab side-window use procedure described in the utility model, handle 9 is pulled to provide in the process of active force downward or upward, move downward or upward with the glass holder profile 7 that side window glass 8 is fixedly connected with, glass support beam 6 and slide block 18 are all synchronous, slide block drives each anglec of rotation be flexibly connected between the upper each parts (mainly crank 15 and connecting rod 16) connected of point to change, preloading spring 4 provides pretightning force to be passed on slide block 18 by pull bar 13, crank 15 and connecting rod 16, and slide block 18 can be come to a complete stop the optional position on slide rail 17.
The rail transit locomotive cab side-window that the utility model provides can have all using function of current drivers ' cab side window structure, and it has again the advantage that frictional dissipation is little, application life extends simultaneously.The rail transit locomotive cab side-window that the utility model provides, can realize standard-sized sheet and the complete shut-down of side window, and the feature that optional position is surely stopped, and facilitates locomotive crew member to window and observes the situation of pantograph.Side window of the prior art departs from center due to stressed, causes side window outside framework to wear and tear severe, the application life of side window is reduced greatly.And the introducing of the crank connecting rod sliding block mechanism of specific setting in the utility model, change the force-bearing situation of side window, cab side-window center is by upper and lower support force effect, the friction that the eccentric force that side window outside framework is no longer subject to side window inside casing causes, greatly reduce the wearing and tearing of side window framework, extend the application life of cab side-window.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
