Description
Technical field
The utility model relates to locomotive Parking control field, specifically is a kind of locomotive parking control device that can realize electric interlocking between braking and the locomotive operation.
Background technology
Traditional braking during standstill adopts mechanical device, and major part is made up of handwheel, steel rope, pull bar, leading screw etc., and it is big to take up room, install complicated, operation inconvenience (driver must rotate big handwheel, very effort), and can't realize braking and locomotive operation between electric interlocking.When locomotive is in the braking during standstill state, if driver's maloperation and start locomotive can make traction motor be in the stall operation, causes motor overload and damage insulation, even burn motor coil.
Summary of the invention
The utility model for solve the traditional mechanical holding brake device exist take up room big, complicated, operation inconvenience is installed and can't realize braking and locomotive operation between problems such as electric interlocking, a kind of locomotive parking control device is provided.
The utility model is to adopt following technical scheme to realize: the locomotive parking control device, comprise electric control unit and air brake pipeline unit, air brake pipeline unit pack contains parking braking cylinder, and three three-way magnetic valve YC that valve port is communicated with ambient atmosphere respectively, is communicated with vehicle-mounted air compressor and parking braking cylinder by the road, the connecting line between three-way magnetic valve YC and the parking braking cylinder is provided with pressure relay; Described electric control unit comprises and is parallel to the control both ends of power: brakes normally closed button 1SB, alleviates the series arm of often opening button 2SB, three-way magnetic valve YC, and the series arm of the open contact YJ of pressure relay and intermediate relay 1K; Three-way magnetic valve YC two ends are parallel with intermediate relay 2K, the open contact 2K-1 of intermediate relay 2K is parallel to alleviation and often opens button 2SB two ends, the open contact 1K-1 of intermediate relay 1K, normally closed contact 1K-2 connect with relieved state indicator lamp 2HL, braking mode indicator lamp 1HL respectively, and are parallel to the control both ends of power; The open contact 1K-3 of intermediate relay 1K is series in the current supply circuit of main circuit of electric locomotive excitation contactor magnet coil 1KM.
Working process is as follows: during the locomotive braking during standstill, in the connecting line in the parking braking cylinder, between parking braking cylinder and the three-way magnetic valve is barometric pressure, the open contact YJ of pressure relay is in off-state, intermediate relay 1K dead electricity, its open contact 1K-1,1K-3 disconnect, normally closed contact 1K-2 closure, relieved state indicator lamp 2HL goes out, 1HL is bright for the braking mode indicator lamp, the current supply circuit of main circuit of electric locomotive excitation contactor magnet coil 1KM is in off state, has avoided occurring owing to the situation that driver's maloperation causes starting locomotive under braking mode; When alleviating before locomotive starts, press alleviation and often open button 2SB, intermediate relay 2K gets, the open contact 2K-1 closure of intermediate relay 2K, form locking, unclamp alleviation and often open button 2SB, three-way magnetic valve YC gets electric, and parking braking cylinder is in inflated condition, when the pressure in the parking braking cylinder reaches when releasing the pressure, the open contact YJ closure of pressure relay, intermediate relay 1K gets electric, its open contact 1K-1, the 1K-3 closure, normally closed contact 1K-2 disconnects, and 2HL is bright for the relieved state indicator lamp, braking mode indicator lamp 1HL goes out, the current supply circuit of main circuit of electric locomotive excitation contactor magnet coil 1KM is in channel status, and locomotive can normally start; When wanting stopping brake, press the normally closed button 1SB of braking, three-way magnetic valve YC dead electricity, make parking braking cylinder switch to logical atmospheric condition pressure release, spring in the parking braking cylinder is realized braking during standstill, and simultaneously, the open contact YJ of pressure relay disconnects, intermediate relay 1K dead electricity repeats the state of above-mentioned glancing impact.
Compared with prior art, the utility model is set up pressure relay on the three-way magnetic valve YC of air brake pipeline unit and the connecting line between the parking braking cylinder, the contacts status of pressure relay is relevant with braking, the relieved state of air brake pipeline unit; Air brake pipeline unit is strengthened related by the open contact of pressure relay with electric control unit, electric control unit is by contact and the main circuit of electric locomotive electric interlocking of intermediate relay 1K, realize the electric interlocking of locomotive braking during standstill and running under power, guarantee only when locomotive is alleviated fully, main circuit of electric locomotive excitation contactor magnet coil just has excitation output, locomotive could also move by normal starting, effectively prevent cycling start when locomotive is in braking mode owing to driver's maloperation, minimizing improves the locomotive operation reliability to the damage of parts such as motor, brake shoe; The normally closed button 1SB of braking is set, alleviates and often open button 2SB, relieved state indicator lamp 2HL, braking mode indicator lamp 1HL, the driver only need press braking or alleviate and often drive button, the automatic alleviation that locomotive braking during standstill or cycling start are preceding can be realized, and the control of braking state of current locomotive can be confirmed by led status.
The utility model is rational in infrastructure, simple, and is convenient and simple for operation, and the reliability height is adapted at using on all kinds of hauling engines.
