Abstract
A conveniently-maintained braking resistor device for railway locomotive and underground train comprises a blower, an air outlet drum, and a resistor cabinet. The resistor cabinet includes a blower mounting plate, a lower sealing plate, a stopper plate, a guide rail, left and right lateral plates, an air pressure switch, a temperature protective device, a braking resistor outlet box, rollers, resistor elements, an upper sealing plate, a braking resistor suspending device, and an insulator. Each resistor element is inlaid into a pair of guide rail chutes. The stopper plate is arranged under the guide rail for preventing detachment of the resistor elements. Four mica plates arranged on each resistor element and in vertical and horizontal directions form an air duct in front and back directions. Twelve resistor elements are arranged in parallel to form a total air duct. The resistor elements to be maintained can be conveniently dragged out of the resistor cabinet, from which the lower sealing plate is dissembled, so the utility model has the advantages of convenient maintenance, labor-saving, time-saving, and reduced cost.
Description
Technical field
The utility model relates to a kind of railway locomotive easy to maintenance, Brake resistance device for metro vehicle.
Background technology
Braking resistor is a kind of being installed on railway locomotive, the railcar, the electric apparatus that when rolling stock adopts regenerative brake unnecessary electric energy is converted to heat energy and makes it to dissipate.Because the heat element of braking resistor is that resistance unit heats repeatedly for a long time, cools off, and adds the vibration of rolling stock, thereby cause resistance unit overheated or short circuit scaling loss easily, so its frequency of maintenance is the highest.And for traditional design, resistance unit all is to adopt with the braking resistor cubicle skeleton to fixedly mount by insulator, when resistance unit need be safeguarded, must unload braking resistor and disassemble the resistor box skeleton from vehicle, not only the labour intensity of service personnel is big, and maintenance time is long, the cost height.
Summary of the invention
The purpose of this utility model is to provide a kind of railway locomotive easy to maintenance, Brake resistance device for metro vehicle, and it should be able to overcome the defective of prior art, obviously reduces and safeguards labour intensity, shortens maintenance time, reduces maintenance cost.
The technical solution of the utility model is---a kind of railway locomotive easy to maintenance, Brake resistance device for metro vehicle, it comprises blower fan, chimney fan and resistor box, it is characterized in that: described resistor box contains blower fan adapter plate, following shrouding, ends plate, guide rail, left side plate, blast switch, temperature protective device, braking resistor outlet box, roller, resistance unit, upper sealing plate and braking resistor erecting by overhang and insulator; Described resistance unit is embedded on the guide rail by roller and ends plate in case anti-avulsion goes out by being installed under the guide rail, and guide rail then is connected and fixed by insulator and left side plate, forms a pull-alongs resistance unit system;
Described guide rail respectively is symmetrically installed with 12 on left side plate, and a resistance unit is installed on symmetrical per 2 guide rails, and resistance unit is embedded in the guide rail chute by 4 rollers and can moves along chute; Each resistance unit also has the air channel of 4 agalmatolite plates composition fore-and-aft direction up and down except that 4 rollers are respectively arranged, just form a total air channel after 12 resistance units are installed side by side.
The skeleton of above-mentioned resistor box is formed by connecting with screw by 4 3mm plate irons of left-right and front-back, and disassembly and assembly are convenient, and they are left side plate, blower fan adapter plate and chimney fan adapter plate.
The most outstanding advantage of the present utility model is easy to maintenance, after certain resistance unit in the device goes wrong, only need to pull down the following shrouding of resistor box from the vehicle bottom, unload the copper busbar of connection resistance unit and the only plate on the respective track then, just the resistance unit that needs are safeguarded can be hauled out from the guide rail chute, not only laborsaving but also save time.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure, 1-blower fan, 2-blower fan adapter plate; 3-following shrouding, 4-only plates, 5-guide rail; 6-left side plate, 7-blast switch, 8-temperature protective device; 9-braking resistor outlet box, 10-roller, 11-resistance unit; 12-upper sealing plate; 13-chimney fan, 14,15-braking resistor erecting by overhang, 16-insulator.
The specific embodiment
Referring to accompanying drawing; a kind of railway locomotive easy to maintenance, Brake resistance device for metro vehicle; it comprises blower fan 1, blower fan adapter plate 2, down shrouding 3, end plate 4, guide rail 5, left side plate 6, blast switch 7, temperature protective device 8, braking resistor outlet box 9, roller 10, resistance unit 11, upper sealing plate 12, chimney fan 13, braking resistor erecting by overhang 14,15 and insulator 16.Wherein blower fan adapter plate 2, left side plate 6 and chimney fan 13 adapter plates constitute the resistor box skeleton, resistor box skeleton and shrouding 12,3 and end plate 4, guide rail 5, blast switch 7, temperature protective device 8, braking resistor outlet box 9, roller 10, resistance unit 11 and add braking resistor erecting by overhang 14,15 and insulator 16 composition resistor boxs up and down.Each element in 12 resistance units 11 all is embedded in the chute of guide rail 5 of a pair of balanced configuration by 4 rollers 10, because end is equipped with only plate 4 under each guide rail chute, deviates from from the guide rail chute so can prevent resistance unit; Guide rail 5 then is connected and fixed by insulator 16 and left side plate 6, forms a pull-alongs resistance unit system; Each resistance unit also has the air channel of 4 agalmatolite plates composition fore-and-aft direction up and down except that 4 rollers are respectively arranged, just form a total air channel after 12 resistance units are installed side by side in order to the cooling resistance unit that ventilates.When certain resistance unit needs to be serviced, only need to pull down the following shrouding 3 of resistor box, unload the copper busbar of connection resistance unit and the only plate 4 of respective track lower end then, just respective resistive elements can be hauled out from the guide rail chute and safeguard from the vehicle bottom, not only laborsaving but also save time, cost is also low.
