Abstract
The invention discloses a parking brake state indicator of a railway locomotive. The parking brake state indicator comprises a shell, a cylinder and piston assembly and a color plate. The cylinder and piston assembly is positioned in the shell 1, a display window 2 is arranged on a side surface of the shell 1, a lower port of a cylinder 3 is connected to a parking brake pipe 9, the lower end of a spring 4 in the cylinder 3 presses a piston 5, the upper end of the spring 4 is butted to the inner side of an upper end cover of the cylinder 3, the lower end of an upright column 6 is hinged to the piston 5 by a hinge pin 7, the upper end of the upright column 6 penetrates a hole of the upper end cover of the cylinder 3 via the spring 4, the inverted-L-shaped color plate 8 is close to the display window 2 and is fixed to the upper end of the upright column 6, and different colors are coated on the inverted-L-shaped color plate 8 from top to bottom in a sectionalized manner. The parking brake state indicator of the railway locomotive has the advantages that the parking brake state indicator is of a purely mechanical structure and can be used even if the locomotive is not powered on; parking brake implementation and relief of the locomotive can be indicated by the different colors according to a pressure condition of the parking brake pipe, accordingly, operation staffs can conveniently judge and identify a parking brake state of the locomotive, and the operation safety can be improved.
Description
Technical field
The present invention relates to a kind of railway locomotive parking brake positioning indicator, belong to railway locomotive manufacturing technology field.
Background technology
When the locomotive long period stops or parks for a long time, need to implement parking brake to locomotive.Trainman is indoor has parking brake indicator lamp, when red to represent that parking brake implements, and red light goes out and represents that parking brake alleviates.The outer service personnel of car, as needed the locomotive under repairing bogie truck lower external device of waiting for bus, must first confirm whether locomotive has implemented parking brake.But vent external does not have parking brake state indicating device, service personnel must be got on the bus and be entered the state that driver's cab could be observed parking brake indicator lamp.If locomotive microcomputer does not power on, parking brake indicator lamp can not be used, and this causes a lot of inconvenience to service personnel.
Summary of the invention
Object of the present invention overcomes the deficiency of above-mentioned prior art exactly, and a kind of railway locomotive parking brake positioning indicator is provided, and makes service personnel can know and whether locomotive implemented to parking brake under car.
The object of the present invention is achieved like this: a kind of railway locomotive parking brake positioning indicator, it is characterized in that by housing, cylinder piston assembly and colour table form, cylinder piston assembly is positioned at the housing that side has display window, the lower port of cylinder body is connected to parking brake pipe, in cylinder body, the lower end of spring is pressed on piston, upper end withstands on the upper end cover inner side of cylinder body, the lower end of column is by bearing pin and piston hinge, upper end passes from the upper end cover hole of cylinder body through spring, near display window, the inverted L-shaped colour table that segmentation scribbles different colours is from top to bottom fixed on the upper end of column.
Technical scheme of the present invention is Purely mechanical structure, is arranged on vent external visibility point, even if locomotive does not power on, also can not use.According to parking brake pipe pressure situation, with enforcement and the alleviation of different colours indication locomotive parking brake.Handled easily personnel identify the judgement of locomotive parking brake state, have improved the safety of operation.
Accompanying drawing explanation
Fig. 1 is the railway locomotive parking brake positioning indicator principle schematic (enforcement state) of the embodiment of the present invention.
Fig. 2 is the railway locomotive parking brake positioning indicator principle schematic (alleviation state) of the embodiment of the present invention.
In figure, be labeled as: 1-housing, 2-display window, 3-cylinder body, 4-spring, 5-piston, 6-column, 7-bearing pin, 8-colour table, 9-parking brake pipe.
The specific embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Referring to accompanying drawing, the railway locomotive parking brake positioning indicator of the present embodiment, be arranged on vent external visibility point, by housing, cylinder piston assembly and colour table form, cylinder piston assembly is positioned at the housing 1 that side has display window 2, the lower port of cylinder body 3 is connected to puts parking brake pipe 9, in cylinder body 3, the lower end of spring 4 is pressed on piston 5, upper end withstands on the upper end cover inner side of cylinder body 3, the lower end of column 6 is by bearing pin 7 and piston hinge, upper end passes from the upper end cover hole of cylinder body through spring, near display window 2, the inverted L-shaped colour table 8 that segmentation scribbles different colours (for example red and green) is from top to bottom fixed on the upper end of column.
Implement parking brake, parking brake pipe 9 is in low pressure passive state even, and the spring 4 in cylinder piston assembly is free state, and piston 5 is positioned at bottom dead point, and the red color area section on colour table 8 is positioned at display window 2.
Parking brake is alleviated, and parking brake pipe 9 is in high pressure conditions, and the spring 4 in cylinder piston assembly becomes compressive state by free state, and piston 5 is positioned at top dead point, and the green section on colour table 8 is positioned at display window 2.
Finally it should be noted that: above embodiment only, in order to technical scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
