Abstract
The utility model discloses a sealed rain-proof structure for an engine top cover. The sealed rain-proof structure consists of a large cover, detachable top covers, a movable beam, glue strips and a swing bolt, wherein the large cover and the detachable top cover are connected by adopting the swing bolt, and sealed by a longitudinal sealing glue strip; the detachable top covers are in sealed connection with transversal sealing glue strips through the movable beam; an upward flanging of a covering of the large cover is coherent and has no notch along the engine; a rain preventing groove end head bends downwards to be buckled on the outer side of the upward flanging of the covering of the large cover; the longitudinal sealing glue strip is positioned between the end head, of rain preventing groove, bending downwards and the upward flanging of the covering of the large cover. Sealing and rain preventing of the engine top cover are well solved, rainwater is prevented from entering into a machine room, meanwhile, the mounting of the movable beam is relatively convenient and accurate, the processes are reduced, the work efficiency is improved, the cost is reduced, the trouble that the movable beam is needed to be glued again after being disassembled is avoided, noise is effectively reduced under an engine starting condition, a buffer function is played on the collision of part, and a function of protecting the parts is played.
Description
Technical field
The utility model relates to a kind of locomotive top cap sealing rain-proof structure, belongs to railway locomotive technical field.
Background technology
The two driver's cab diesel locomotives of inside corridor formula of prior art often adopt ceiling structure.Ceiling is divided into detouchable top cover two parts between large lid and each machinery.Large lid is connected with removable top employing eyelet bolt, and seals with sealing joint strip.Between each machinery, top cover is detachable, is convenient to in-vehicle device lifting.So require sealing rain-proof structure can be repeatedly used and keep its sealing property.(seeing accompanying drawing 1,2).There is following problem in this scheme:
(1) existing ceiling structure form, the eaves that keeps off the rain that covers greatly the flange of keep off the rain groove and the large lid that connect removable top is interfered, and need to cover greatly gap, plays glue sealing around the groove that keeps off the rain after welding.If the defect of being welded with, sealant is aging easily to come off, and sealing effectiveness can variation, causes roof leaking, and rainwater enters between machinery, and electric wiring, pipeline system are corroded, and so goes down and can bury potential safety hazard to locomotive and personnel, also may cause machine broken.(seeing accompanying drawing 3,4,5).
(2), referring to accompanying drawing 6a, 6b, due to large lid covering flange identical with the height of the groove that keeps off the rain (the b point position in figure), cause sealing joint strip to turn elbow bend at both intersections.The material of adhesive tape own has certain degree of hardness, can not be converted into right angle completely, thereby easily forms around the corner gap, also easily causes and leaks equally.
Utility model content
The purpose of this utility model overcomes the deficiency of above-mentioned prior art exactly, and a kind of locomotive top cap sealing rain-proof structure is provided.
The purpose of this utility model is achieved in that a kind of locomotive top cap sealing rain-proof structure, by covering greatly, removable top, portable beam, adhesive tape, eyelet bolt forms, large lid adopts eyelet bolt to be connected with removable top, and use longitudinal sealing adhesive tape sealing, between removable top, be connected sealing by moved cross beam with transverse sealing adhesive tape, it is characterized in that the non-notch that longitudinally links up to upper overturning along locomotive of described large lid covering, groove end the interlocking to bending under upper overturning lateral at large lid covering of keeping off the rain, longitudinal sealing adhesive tape the reclinate termination of the groove that keeps off the rain and cover greatly covering between upper overturning.
Scheme of the present utility model, the sealing that has solved well locomotive header is rainproof, has avoided rainwater to flow between machinery, make the easier for installation, accurate of portable beam simultaneously, reduced operation, increase work efficiency, reduce costs, avoided needing again to beat after portable beam dismounting the trouble of glue.Open under machine state and effectively reduce noise at locomotive, the collision between each several part is played to buffer action, play the effect of the each parts of protection.
Brief description of the drawings
The locomotive top cap sealing rain-proof structure schematic diagram that Fig. 1～5, Fig. 6 a and Fig. 6 b are prior art.
Fig. 7～9 are the locomotive top cap sealing rain-proof structure schematic diagram of the utility model embodiment.
In figure, be labeled as: the large lid of 1-, 2-removable top, 3-eyelet bolt, 4-adhesive tape, 5-transverse sealing adhesive tape, 6-moved cross beam, 7-breach, the large lid covering of 8-, the 9-groove that keeps off the rain, 10-sealant, the large lid covering of 11-is to upper overturning, and the 12-groove that keeps off the rain is bent downwardly termination, 13-longitudinal sealing adhesive tape.
Detailed description of the invention
Referring to Fig. 7～9, the locomotive top cap sealing rain-proof structure of the present embodiment, covers greatly 1 and adopts eyelet bolt 3 to be connected with removable top 2, and seals by longitudinal sealing adhesive tape 13, between removable top 2, is connected sealing by moved cross beam 6 with transverse sealing adhesive tape 5.The non-notch that longitudinally links up to upper overturning 11 along locomotive of large lid covering 8, keep off the rain groove end 12 being bent downwardly and interlocking to upper overturning 11 outsides of large lid covering 8, longitudinal sealing adhesive tape 13 the reclinate termination 12 of the groove that keeps off the rain and cover greatly covering 8 between upper overturning 11.This structure, without flange 11 gaps to large lid covering 8, ensures the continuity of this flange weather shield along locomotive longitudinal direction, can well avoid rainwater to flow between machinery from indentation, there, reaches the object of protection the inside equipment.Owing to cancelling breach, avoid issuable error in the course of processing simultaneously, made the easier for installation of portable beam, reduce welding capacity and distortion, improved product design, reduced operation, raising work effect, has reduced cost, and also having avoided needs again to beat glue after portable beam dismounting.Between both direction sealing joint strip, do not produce in length and breadth any contact, separate, avoid the space producing because of adhesive tape knuckle.Top cover installation, can be realized transverse and longitudinal sealing joint strip and compress simultaneously tight by eyelet bolt, reaches the rainproof effect of sealing.Removable top and cover greatly flange, portable beam and keep off the rain and use sealing joint strip involution between groove; prevent that rainwater from entering; sealing joint strip can play buffer action to the collision between each several part, can play at locomotive and open under machine state and effectively reduce noise, has also reached the object of protecting each parts.
Claims (1)
1. a locomotive top cap sealing rain-proof structure, formed by large lid, removable top, portable beam, adhesive tape, eyelet bolt, large lid adopts eyelet bolt to be connected with removable top, and use longitudinal sealing adhesive tape sealing, between removable top, be connected sealing by moved cross beam with transverse sealing adhesive tape, it is characterized in that the non-notch that longitudinally links up to upper overturning along locomotive of described large lid covering, keep off the rain groove end the interlocking to bending under upper overturning lateral of large lid covering, longitudinal sealing adhesive tape the reclinate termination of the groove that keeps off the rain and cover greatly covering between upper overturning.
