Abstract
The invention relates to a diesel locomotive muffler mounting structure. A reinforcing ring 10 is arranged on the inner side of a shell nearby an exhaust port of a muffler, a connecting lug 11 extending outwards from the reinforcing ring is arranged at the mounting position of the shell, a mounting framework 1 is in a -shaped structure with two ends fixed on a large cover 5 of a locomotive body, and supporting columns 3 parallel to framework side legs 2 and a crossbeam 4 of the framework form a T-shaped support. The connecting lug 11 is seated on a mounting seat 12 mounted on the crossbeam of the framework, and fastened through a bolt structure 13. The muffler is ensured to be mounted firmly and prevented from vibration, the problem that a skin of the muffler is torn is solved, a rain cover and a head cover are prevented from colliding with each other, and noise produced due to vibration of the muffler in the locomotive running process is lowered effectively. Besides, the muffler is convenient to mount and dismount, and beneficial to overhauling and maintenance.
Description
Technical field
The present invention relates to a kind of diesel locomotive mounting structure of silencer, belong to the railway locomotive technical field.
Background technology
The installation of diesel locomotive silencer, normally rainproof cover and chuck for installing are welded on to the removable top cover covering of diesel engine top, the silencer air duct passes top cover from the removable top cover lower opening, by adjusting after pad is adjusted height, with chuck for installing, tighten, silencer hangs on the removable top cover below, after assembling, fully by top cover carrying, interface is connected with diesel engine with diesel smoke pipe pipe clamp below silencer.In order to lift the maintenance diesel-engine equipment, top cover is generally all detachable, and only by eyelet bolt, connects between both walls, is not rigidly connected.Produce strong air-flow during diesel engine work, can make the silencer strenuous vibration, and then drive the top cover vibrations, cause the silencer covering to tear damage, or it is insecure to cause diesel smoke pipe pipe clamp place to be connected with diesel engine, easily causes gas leakage.Silencer only relies on chuck to be fixed in below top cover simultaneously, and the end face covering generally adopts thin plate, and long-time vibrations may cause the top cover distortion.And silencer also easily produces strong noise with the top cover vibrations.In addition, because silencer hangs on the top cover below, from following installation or removal silencer, very inconvenient after top cover need to being sling during maintenance.
Summary of the invention
Purpose of the present invention overcomes the deficiency of above-mentioned prior art exactly, and a kind of diesel locomotive mounting structure of silencer is provided.
The object of the present invention is achieved like this: a kind of diesel locomotive mounting structure of silencer is characterized in that:
Near the housing inboard silencer exhausr port is provided with fixing collar, in the installation position of housing, arranges by the outwardly directed connection lug of fixing collar;
Mounting framework is that two ends are fixed in car body and are covered greatly
The shape structure, arrange the pillar parallel with skeleton side leg, with the crossbeam of skeleton, forms the support of T shape;
Described connection lug is sitting on the mount pad on the mounting framework crossbeam, fastening by bolt arrangement.
In order to realize better purpose of the present invention, described fixing collar consists of rectangular tube, and described connection lug consists of the wedge-like rectangular tube.
The solution of the present invention, can not only guarantee the silencer installation firmly, avoid the silencer vibrations, solve the silencer covering and torn problem, prevented from colliding between rainproof cover and top cover, effectively reduced the noise produced because of the silencer vibration in the locomotive operation process.But also make the Assembly &Disassembly of silencer convenient, be conducive to repair and maintenance.
The accompanying drawing explanation
The diesel locomotive mounting structure of silencer principle schematic that Fig. 1 is the embodiment of the present invention.
The A-A that Fig. 2 is Fig. 1 is to part sectional view.
In figure, be labeled as: the 1-mounting framework, 2-skeleton side leg, the 3-pillar, the 4-framework beam, the large lid of 5-, the 6-side wall, the 7-underframe, the 8-silencer, the 9-diesel engine, the 10-fixing collar, 11-connects lug, 12-mount pad, 13-bolt arrangement.
The specific embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment obtained, belong to the scope of protection of the invention.
Referring to accompanying drawing 1, the diesel locomotive mounting structure of silencer of the present embodiment, for two ends are fixed in, car body covers greatly its mounting framework 1
The shape structure, arrange the pillar 3 parallel with skeleton side leg 2, with the crossbeam 4 of skeleton, forms the support of T shape.Mounting framework 1 firmly is connected with large lid 5, cover greatly 5 and side wall 6, partition wall (not shown) between weld, side wall, partition wall are welded on underframe 7.Be and be rigidly connected between each several part, combine together, can make silencer 8 and diesel engine 9 be fixed on underframe 7, stable connection simultaneously.Pillar 3 and the T-shaped support that framework beam 4 forms, can evenly transmit the various load that silencer 8 brings.
Referring to Fig. 2, near housing inboard silencer 8 exhausr ports surrounds fixing collar 10 with rectangular tube, in the installation position of housing, by rectangular tube fixing collar 10 openings, inserts the wedge-like rectangular tube and connects lug 11, full weld on every side.Connection lug 11 is sitting on the mount pad 12 on mounting framework crossbeam 4, fastening by bolt arrangement 13, evenly bears the weight of silencer 8.
Finally it should be noted that: above embodiment only, in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment, the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: its technical scheme that still can put down in writing aforementioned each embodiment is modified, or part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of various embodiments of the present invention technical scheme.
