Embodiment
Further specify the technical scheme of the embodiment of the invention below in conjunction with accompanying drawing and specific embodiment.
Fig. 1 is the structural representation of locomotive engine power line water-tight device embodiment of the present invention.Please with reference to Fig. 1; The locomotive engine power line water-tight device that present embodiment provides comprises; One has the bucker 1 of accommodation space, offers the cabling hole 12 of at least one on the end face of bucker 1, and power line is arranged in respectively in the cabling hole 12; Be set with the elastic joint part 112 of accordion around each cabling hole 12, and elastic joint part 112 is fixedly connected with the circumferential surface of power line; Bucker 1 is fixedly attached on the locomotive car body floor around the motor inserting-coil mouth.Particularly; Bucker 1 can be for comprising the cube of end face and side; Its inner accommodation space that forms; Its end face can be used as the anti-water surface 11, can adopt mode such as gluing to achieve a fixed connection between the circumferential surface of elastic joint part 112 and power line, can adopt mode gluing or that weld to be fixedly connected between bucker 1 and the motor inserting-coil mouth locomotive car body floor on every side; Wherein, It is the multilayered fold of ring-type of axle that elastic joint part 112 can be arranged to the power line; The existence of these folds; Make the elasticity of elastic joint part 112 better, make when vehicle operating, power line locomotive car body floor relatively moves within the specific limits and reduces the destruction of pullling to being fixedly connected between power line and the cabling hole 12.
From the above; The locomotive engine power line water-tight device of present embodiment; Through the motor inserting-coil mouth is sealed in the inside of bucker 1, thereby realized that anti-sealing flow to the effect at the connection box for motor place of car body underframe below along power line, can also play the good dust-proof effect simultaneously; Guarantee the trouble free service of locomotive engine circuit, thereby further ensured the safe operation of train.
In the above-described embodiments, as shown in Figure 1, bucker 1 is processed by elastomeric material, and the bottom of bucker 1 extends to form the mount pad 21 that is used to be installed on the locomotive car body floor towards periphery.Particularly, elastomeric material can adopt rubber, fitting with the locomotive car body floor surface better; Extended mount pad 21 has increased the contact area of bucker 1 and locomotive car body floor surface, makes being connected around the motor inserting-coil mouth on the locomotive car body floor that bucker 1 can be more firm, has improved this locomotive engine power line water-tight device dependability.
In the above-described embodiments, as shown in Figure 1, the bottom surface of mount pad 21 is provided with and is used to be bonded to the binder on the locomotive car body floor; The end face of mount pad 21 is provided with and is used for bucker 1 is screwed to the rigidity press strip 3 on the locomotive car body floor.Particularly, adhesive can adopt glass cement; Can be earlier on the locomotive car body floor around the locomotive winding installing port position of corresponding mount pad 21 weld a plurality of bolts (also can weld a plurality of nuts); Then on the locomotive car body floor position of corresponding mount pad 21 smear one the circle glass cement; The position of corresponding bolt is put bucker 1 and rigidity press strip 3 successively again; After utilizing nut to screw at last, accomplished that just bucker 1 is fixedly attached to the operation on the locomotive car body floor.Wherein, being arranged on to also help when playing adhesive effect of glass cement remedies exist on the locomotive car body floor uneven, makes bucker 1 and the locomotive car body floor can good seal; The fixed connection mode of this adhesive fitted bolt, simple to operate, quality of connection is high, has further improved airtight quality.
In the above-described embodiments; As shown in Figure 1, elastic joint part 112 is fastened on the circumferential surface of power line through band 2, and is provided with binder between elastic joint part 112 and the power line; Particularly; Binder can be glass cement, utilize glass cement to seal up the slit between said power line and the elastic joint part 112 after, with band elastic joint part 112 is tied up on the side of power line again; Binder can seal up small gaps not enough because of cabling hole 12 machining accuracies or that the power line air spots forms between power line and elastic joint part 112; Prevent to have improved sealing property, simultaneously by too coarse cause poorly sealed close in power line surface; Cooperate the fastening effect of band; Make power line and elastic joint part 112 firmly, link into an integrated entity closely,, also can guarantee the sealed waterproof effect good the electrical locomotive power line even under locomotive operation jolts bigger situation.
Fig. 2 is the structural representation of rigidity press strip 3 among Fig. 1.In the above-described embodiments, as shown in Figure 1, bucker 1 and mount pad 21 are rectangle, and rigidity press strip 3 is the rectangle frame of a side opening of corresponding mount pad 21, and mount pad 21 is provided with rigidity press strip 3 and is used for the installation through holes 23 that bolt passes.The next door of general motor inserting-coil mouth on the locomotive car body floor all is provided with the gantry beams that is used for installing the main variable flow cabinet; In this case; Can a limit of the mount pad 21 of rectangle be pressed against the bottom of this gantry beams; Mount pad 21 remaining three limit are fastened on the floor with rigidity press strip 3,, further improve the efficient of locomotive assembling to make things convenient for the fitting operation of this water-tight device.
The embodiment of the invention provides a kind of locomotive, comprise locomotive car body and be arranged on the locomotive car body floor like the locomotive engine power line water-tight device among above-mentioned arbitrary embodiment.The locomotive of present embodiment; Setting through locomotive engine power line water-tight device has prevented that water from flowing to the connection box for motor place of car body underframe below along power line; Play excellent waterproof, dustproof effect, guaranteed the safety of locomotive engine circuit, further ensured the safety traffic of locomotive.
What should explain at last is: above embodiment is only in order to explaining technical scheme of the present invention, but not to its restriction; Although with reference to previous embodiment the present invention has been carried out detailed explanation, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these are revised or replacement, do not make the spirit and the scope of the essence disengaging various embodiments of the present invention technical scheme of relevant art scheme.
