Abstract
The utility model relates to a freeze-proofing apparatus of a door lock for a carriage door of a railway passenger train, which belongs to the technical field of railway vehicles. The utility model is provided with a heating element 5 inside; the inner and the outer sides of the heating element 5 are respectively provided with insulating protective layers 4, 6; the insulating protective layer 4 on the inner side is coated on a heat radiating layer 3, and the insulating protective layer 6 on the outer side is coated on an insulating layer 7 and a casing body protective layer 8. The utility model has the advantage of good freeze-proofing effect that the freeze-proofing problem of the carriage door of the passenger train can be fully solved; the utility model has the advantages of simple structure and convenient installation without changing the existing structure of a vehicle body; the utility model has the advantages of high heat efficiency, high speed of one-way heat radiation, low heat loss and small electrical power occupation of the vehicles; the utility model can be safety by that the utility model has a function of automatic overheat protection, and the overheat protection value can be chosen as required; the utility model also has the advantages of explosion proof, fire proof, all-weather work and long service life without pollution.
Description
Technical field
The utility model relates to a kind of defroster that is contained on the passenger train stopping sliding door door lock.Belong to the rail truck technical field.
Background technology
At present, the domestic defroster that also is not used in the stopping sliding door door lock.In northern China winter, because passenger vehicle stopping sliding door door lock freezes, make stopping sliding door to open, influence the normal operation of passenger vehicle.
Summary of the invention
The purpose of this utility model is the defective at above-mentioned existence, proposes a kind of door lock defroster that is used on the passenger train stopping sliding door, and this defroster can guarantee that the stopping sliding door door lock can normally use at extremely frigid zones.Technical solution of the present utility model: in adorn a heater, in the inside and outside both sides of heater insulating protective layer is set respectively, its inboard insulating protective layer covers heat dissipating layer, outside insulating protective layer covers insulation layer and housing overcoat.
Housing overcoat arranged outside temperature regulating device.Temperature regulating device adopts electronic temperature transmitter or machinery control temperature pick up.
Make the door lock zone form a relative closure space at door lock arranged outside case, contact with door lock to reduce extraneous moisture laden air; Make case self produce heat by certain mode, make this closed area keep higher temperature, to prevent moisture laden air condensation and door lock of thawing and having freezed on door lock.Advantage of the present utility model: 1. good freezing protection effect can solve the antifreeze problem of passenger train stopping sliding door fully; 2. simple in structure, easy for installation, need not to change existing body construction; 3. heating efficiency height, the unidirectional speed of distributing of heat is fast, and thermal losses is low, and it is little to take vehicle electrical power; 4. safe and reliable, establish automatic overheat protective function, the overtemperature value can be selected as required; 5. have explosion-proof, fire prevention and all weather operations, long service life, pollution-free.
Description of drawings: accompanying drawing 1 is that the utility model scheme of installation figure accompanying drawing 2 is 1 to be the door lock defroster among the structural representation figure of the present utility model, the 2nd, passenger train stopping sliding door door lock, the screw of defroster 1 by inclined-plane and side makes the space of a relative closure of door lock internal end of travel on door lock.3 is heat dissipating layer among Fig. 2, and 4 is interior insulating protective layer, and 5 is heater, and 6 is the external insulation overcoat, and 7 is insulation layer, and 8 is the housing overcoat, and 9 is temperature regulating device.
The specific embodiment
Door lock defroster 1 is installed on the door lock 2, interior dress heater 5, heater 5 inside and outside both sides are provided with insulating protective layer 4,6, and inboard insulating protective layer 4 covers heat dissipating layer 3, outside insulating protective layer 6 covers insulation layer 7 and housing overcoat 8, at housing overcoat 8 arranged outside temperature regulating devices 9.Temperature regulating device 9 adopts electronic temperature transmitter or machinery control temperature pick up etc.Heat dissipating layer 3 and insulating protective layer 4 adopt the heat-conducting glue can between insulating protective layer 4 and the heater 6, heater 5 and insulating protective layer 6, and insulating protective layer 6 and insulation layer 7 adopt the adiabatic gum sealing between insulation layer 7 and the housing overcoat 8.After heater 5 heatings; the unidirectional door lock 2 that is distributed to of heat; make the space of door lock 2 relative closures raise; when temperature reaches the antifreeze needed temperature value of door lock, by being installed in the empty temperature device 9 collecting temperature signals on the housing overcoat 8, and judge whether overheated; in case it is overheated then start power-off protection function; to reach safe and energy-conservation effect, the overtemperature value can be selected as required simultaneously, to satisfy different requirements.Heater 5 inboards are used heat-conducting glues and heat dissipating layer 3 are set and make heat be delivered to door lock 2 zones rapidly, improve the thermal efficiency, heater 5 outsides are used adiabatic gum and insulation layer 7 are set and make that heat is difficult to outwards distribute, and reduce thermal losses, and the unidirectional speed of distributing of heat is fast.
