Detailed description of the invention
The cross-sectional view of a kind of cab rear wall that Fig. 1 provides for the embodiment of the present invention; The unitized construction schematic diagram of a kind of cab rear wall that Fig. 2 provides for the embodiment of the present invention, wherein part A is the schematic diagram of wall surface porous metal plate after driver's cab, part B is the combination schematic diagram that after driver's cab, other parts after surface porous metal plate opened by wall, and after this driver's cab, the concrete structure of wall is as follows:
Please refer to Fig. 1, Fig. 2, a kind of cab rear wall of the present invention, comprise base plate of support 101, the first side of base plate of support 101 is provided with skeleton 102, described base plate of support 101 be provided with fire-resistant coating for steel structure layer 104 with described first side second, opposite, side.
In the present embodiment, described base plate of support 101 can all adopt Steel material to make with skeleton 102, and base plate of support 101 and skeleton 102 can adopt and be welded to connect.
In the present embodiment; fire-resistant coating for steel structure layer 104 is fire-retardant paint layer (such as Unitherm(helps the people's livelihood) 38091 fire-retardant paint that a kind of pre-fire expands); after external temperature reaches about 200 DEG C, fire-resistant coating for steel structure layer 104 starts to expand; maximum swelling thickness is about 50 times of original thickness; form isolation layer; can effectively stop heat to be propagated to protected steel structure, prevent steel structure Yin Wendu rise too fast and distortion lose supporting capacity.In the middle of practical application, due in car between machinery the probability of presence of fire comparatively large, preferably wall after driver's cab is provided with one of fire-resistant coating for steel structure layer 104 facing between machinery, thus effectively prevents fires, the embodiment of the present invention is to this and be not particularly limited.
In the present embodiment, preferably, base plate of support 101 and skeleton 102 are coated with rust proofing primer layer 103, get rusty to avoid base plate of support 101 and skeleton 102, fire-resistant coating for steel structure layer 104 is coated on the rust proofing primer layer 103 of described second side, and fire-resistant coating for steel structure layer 104 is coated with top coat layer 105, the color of top coat layer 105 meets the standard color systcm in look synopsis (RAL), ensures that the paint that the outside face of body of wall meets car load beautifies requirement.Wherein, the paint vehicle that the rust proofing primer layer 103 contacted with fire-resistant coating for steel structure layer 104 preferably matches with the material selected by fire-resistant coating for steel structure layer 104 with the paint vehicle of top coat layer 105, to make its connectivity better, wherein, with material connectivity fire-resistant coating for steel structure layer 104 selected by the good paint vehicle of the paint vehicle matched with the material selected by fire-resistant coating for steel structure layer 104 for obtaining by experiment, certainly also can select common rust proofing primer layer 103 and top coat layer 105, the embodiment of the present invention is to this and be not particularly limited.
In addition, the thickness of fire-resistant coating for steel structure layer 104 is preferably 0.64 ~ 0.85mm, and the fire endurance of body of wall steel structure can be made to reach 30 ~ 60 minutes.When wall after driver's cab be provided with fire-resistant coating for steel structure layer 104 one facing to machinery between time; if unexpected presence of fire between machinery; fire-resistant coating for steel structure layer 104 will undergoes rapid expansion; isolation and protection is formed to body of wall; within the time of 30 ~ 60 minutes, stop deformation of wall or cave in, for the safe escape of driver and conductor gains time, certainly; the thickness of fire-resistant coating for steel structure layer 104 can adjust according to the length of fire resistance period, and the present invention is not limited to this.
In the present embodiment, preferably, the rust proofing primer layer 103 of the first side of base plate of support 101 is coated with damping pulp layer 106, thus increases the anti-vibration performance of body of wall, play noise reduction.
In the present embodiment, preferably, between skeleton 102, be provided with cold-proof filler 107, thus increase the heat-insulating property of body of wall.
In the present embodiment, preferably, the first side of base plate of support 101 is provided with breaker plate 108, and breaker plate 108 is fixed on skeleton 102 by rivet, thus increases the sound absorption qualities of body of wall, plays noise reduction.
In addition, when wall after driver's cab be provided with fire-resistant coating for steel structure layer 104 one facing to machinery between time, after driver's cab, the opposite side (i.e. described first side) of wall is towards driver's cab, if in the presence of fire of driver's cab side, damping pulp layer 106, cold-proof filler 107 and breaker plate 108 can play shielding action to fire, heat can not be transmitted to rapidly skeleton 102 at short notice, can ensure that fire between rapid spread to machinery, can not create favorable conditions for organizing fire extinguishing.
In the present embodiment, preferably, the rust proofing primer layer 103 of the first side of base plate of support 101 is coated with fire-resistant coating for steel structure layer 104, to increase the fire performance of body of wall further.
In the present embodiment, preferably, after described driver's cab, the surrounding of wall is provided with and meets fiery expansion adhesive tape 109.Meet fiery expansion adhesive tape 109 can be arranged on driver's cab after wall surrounding and steel structure of car body there is the place in gap, meeting fiery expansion adhesive tape 109 can expand when fire occurs, and stops pyrotechnics and noxious gas string between driver's cab or machinery.
In the present embodiment, wall can be provided with rear wall door 201 after driver's cab, rear wall door 201 can adopt double sealing structure, rear wall door 201 port size can be 650 × 1805, after driver's cab, wall is positioned at driver's cab side and can installs an emergency opening bar that can open the door fast, and the door lock of rear wall door 201 can be opened and reliable locking fast.After driver's cab, wall also carries out grounding by grounding jumper, is used for protecting driver and conductor to avoid unexpected trolley wire and electrostatic.
The cab rear wall that the embodiment of the present invention provides, by arranging fire-resistant coating for steel structure layer, improves the fire resistance of wall and electric locomotive after driver's cab.After driver's cab of the present invention, the coefficient of heat transmission of wall can reach 0.62(watt/sq m. degree).The no matter first presence of fire between machinery or any side of driver's cab, after driver's cab, wall can effectively stop fire to spread to opposite side.
In another embodiment of the present invention, also provide a kind of electric locomotive, to comprise in driver's cab, car between machinery and wall after driver's cab that the invention described above embodiment provides, between wall to be located in driver's cab and car between machinery after described driver's cab.Can be located by connecting with locating dowel pin when wall is installed on the car body of electric locomotive after driver's cab, can sealing adhesive be poured at the gap place with car body periphery.Because wall after driver's cab is provided with fire-resistant coating for steel structure layer, improve the fire resistance of electric locomotive.
Last it is noted that above embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments 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.
