The controlling device of an electric and air brake machine for a locomotive is characterized in that the utility model comprises an integrated electric screen and an integrated air circuit screen, and the two screens are fixed on a frame by screw bolts. The electric screen is composed of components such as a screen board, a relay, a contactor, a socket, an electric integrated package, etc. The integrated air circuit screen is composed of components, such as an air circuit board, an air valve, a pressure switch, an electric and air valve, etc. Various air ducts are arranged in the air circuit board, and a primary brake air cylinder of the electric and air brake machine is replaced by a wide and long air duct arranged in the air circuit board. Each component of the integrated air circuit screen carries out air connection through the air circuit board. The utility model has the advantages compact structure, simple structure, increased brake performance, reliable operation, less maintenance, etc.
Description
The utility model belongs to railway vehicle brake control system category, particularly electro-pneumatic brake control device.
Air damper was adopted in the braking of rolling stock, particularly electric locomotive in the past, and the back is improved and used electro-pneumatic brake, its control is general by brake controller (being commonly called as large and small lock), various air valves, electropneumatic valve, parts such as relay are implemented, these parts often dispersed placement shield at locomotive corresponding site and control of braking, occupy locomotive than large space, and connecting line is long and complicated, adaptor union is a lot, thereby cause brake reaction and opening time longer, leak hidden danger point and reach shortcomings such as maintenance capacity is big more.Adopted brak control unit scheme (with reference to the 1st, 2 phases of " railway vehicle " nineteen ninety-five of four directions vehicle research institute of Ministry of Railways publication) in recent years, this scheme is that the brake snub function unit is installed on the aluminum alloy gas path plate, control setup structure trend is oversimplified, modularization, overcome above-mentioned shortcoming to a certain extent, but exist function simple, connect shortcomings such as loose with electric controling part.
It is complete that the purpose of this utility model provides a kind of controllable function, reliable operation, and traction long and big train time control deceleration and stopping performance is good, compact conformation, simple for assembly process and locomotive electro-pneumatic brake control setup that maintenance capacity is little.
For achieving the above object, the electro-pneumatic brake control setup that the contriver develops includes electric screen and integrated gas circuit screen, and electric screen is by screen board and be installed in relay on the screen board, contactless switch, change-over swith, socket, component set-ups such as electric integrated package; Integrated gas circuit screen is by gas path plate and be installed in air valve, pressure switch on the gas path plate, component set-ups such as electropneumatic valve, and brake is provided with initial service air cylinder, and this reservoir places gas path plate inside, i.e. wide and long groove on the gas path plate base plate; Electric screen and integrated gas circuit screen is by being bolted on the framework, and the parts on two screens are electrically connected by the multicore connector.Gas path plate is synthetic by the welding of base plate and panel, and narrow air drain more than two is arranged on the base plate, wide and long groove and two above pores and screw more than one; Two above circular holes and rectangular opening are arranged on the panel; Electric integrated package on the electric screen is by printed circuit board (PCB) and be installed in second tube sheet on the printed circuit board (PCB), pizo-resistance, toggle switch, component set-ups such as time relay.
Compare with known electro-pneumatic brake control setup, the utility model is owing to concentrated the function unit of electro-pneumatic brakes all except that the big lock of driver's cab, so compact conformation, realized integrated, facilitation, especially various air valves, pressure switch, electropneumatic valve carries out the gas connection by the gas path plate that inside has air drain, numerous connecting tubes have been omitted, valve seat and adaptor union, significantly reduce leakage hidden danger, keep in repair also simply, and overcome because gas circuit length causes the shortcoming grown brake reaction and opening time; External initial service air cylinder with a wide and long groove replacement brake on the gas path plate base plate had both had the effect that improves traction long and big train deceleration and stopping performance, had further simplified control setup again and had alleviated installation weight.
Below in conjunction with accompanying drawing in detail embodiment is described in detail.
The general layout of Fig. 1 locomotive electro-pneumatic brake control setup
Fig. 2 gas path plate base plate
Fig. 3 gas path plate panel
The electric integrated package of Fig. 4
The contriver all concentrates on electric screen (7), integrated gas circuit screen (2) to the electro-pneumatic brake function unit except that the big lock of driver's cab, these two screens are installed on the U-shaped framework (1) by bolt.Electric screen is by screen board and be installed in socket (4) on the screen board, contactless switch (5), intermediate relay (6), electric integrated package (8), change-over swith (10) constitutes, wherein, electric integrated package is by electric wire bonded assembly toggle switch (22) former dispersed placement, second tube sheet (24), pizo-resistance (25), and time relay (26) is welded on the modular unit that printed circuit board (PCB) (23) forms.Integrated gas circuit screen is by gas path plate and installation pressure switch (3) onboard, electropneumatic valve (9), change-over valve (11), relay valve (12), emergency valve (13), electronic vent valve (14), distributing valve (15) formation; Gas path plate is synthetic by base plate (16) and panel (21) soldering, is milled with many narrow air drains (20) on the base plate (16), and wide and long air drain (17) and a plurality of pipe thread hole (18) that connects are installed screw (19), also have some circular holes; Panel (21) has a plurality of circular holes and rectangular opening, the part circular hole on the panel on most of circular hole and the base plate and screw is installed each is corresponding.Narrow air drain (20) on the gas path plate base plate has replaced gas circuit connecting tube complicated originally between each air valve, pressure switch, the electropneumatic valve, and groove (17) has replaced heavier external initial service air cylinder.Parts on electric screen (7) and the integrated gas circuit screen (2) are electrically connected by the multicore connector at the screen back side, and the electrical connection of The whole control device fgn is by socket (4), and the connection of fgn gas circuit realizes by connecing pipe thread hole (18).Need glancing impact in the locomotive operation process, the electricity instruction of the big lock of driver control (being E P brake controller) → big lock enters relevant electrical equipment action → corresponding locking contact on the electric screen → electric screen of this device through socket (4) electric signal enters integrated gas circuit through the multicore connector and shields → command relevant air valve, electropneumatic valve, pressure switch and move → connect or close corresponding gas circuit, make brake enter braking, or alleviate, or pressurize, or urgent, or heavy state such as connection.
The entrucking of this device is through 200,000 kilometers trail runs, and benefit is good, removes and omits numerous valve seats, connect steel pipe and copper pipe, parts such as adaptor union and external initial service air cylinder make beyond cost savings, installation weight alleviate, and mainly are reflected in and have largely reduced leak point, shorten pipeline, the brake performance improves greatly, and makes the electro-pneumatic brake control device facilitation, and is integrated, be convenient to carry out centralization, all many-sides such as automated production.Thereby help the production of locomotive and the raising of drive ability.
