A kind of locomotive car body
Technical field
The utility model relates to a kind of locomotive car body, relates in particular to each machine chamber side wall and top cover detouchable locomotive car body in a kind of locomotive, belongs to the diesel locomotive technical field.
Background technology
The pattern of conventional locomotive car body is divided into outside hall type and inside corridor formula.In China, outside hall type locomotive all is be used to the hauling engine of shunting basically, and inside corridor formula locomotive then is used for the main line hauling engine.The locomotive of two kinds of patterns is according to the difference of its effect and greatest differences is arranged in shape.Imbody is as follows: traditional outer corridor locomotive car body driver's cab generally all is arranged in locomotive end or close end, but driver's cab, other machine chamber side wall, partition and main car frame are by weld together, and top cover and side wall etc. is actively coupled by modes such as bolts; And the nearly all driver's cab of inside corridor locomotive car body is arranged in two ends, driver's cab, side wall and main car frame weld together, and top cover and side wall etc. is actively coupled by modes such as bolts.In addition, the nearly all locomotive that moves in Chinese Railway all adopts all steel welding car body, especially inside corridor locomotive, all is the structure that is welded as a whole between its car body main car frame, driver's cab and vehicle body side wall, the partition wall.This body construction is assembled at locomotive, large, the sight line of Existential Space limitation and light difference when inspection and maintaining, deficiency that the operability limitation is larger.
The utility model content
The purpose of this utility model is: a kind of locomotive car body is provided, main car frame top body construction is designed to movable removable structure, the above part of car body main car frame is connected by movable bolt with main car frame, by the above part of detouchable main car frame, make locomotive when assembling, examination and maintenance maintenance, solve the existing technical matters that the locomotive attainability is not high, use and maintenance is inconvenient, thereby can solve above-mentioned problems of the prior art by actv..
The purpose of this utility model is to realize by following technical proposals: a kind of locomotive car body, comprise main car frame and car body, and described car body comprises side wall, partition, driver's cab and covering for roofs, is movable demountable structure between described car body and the main car frame.
As optimal way, bolt connects between described side wall and the covering for roofs.
As another optimal way, described side wall and covering for roofs are the integral type structure.
As optimal way, described main car frame is that bolt is connected with side wall, and main car frame is that bolt is connected with driver's cab.
Compared with prior art, the beneficial effects of the utility model: the utility model locomotive car body adopts Split type structure, improved the comfort feature of locomotive when assembling and Maintenance and Repair, each machine chamber side wall, top cover and main car frame all detachably separate, so that the equipment that is installed on the main car frame can be presented to the operator fully, carrying out locomotive when always assembling, each equipment can be assembled at the platform of main car frame on the car, greatly strengthen the space availability ratio of locomotive assembling, improved the manufacturability of locomotive, maintenance is convenient.

Fig. 1 is the structural representation of locomotive car body;
Fig. 2 is the cross section structure schematic diagram of Fig. 1;
Fig. 3 is A place enlarged diagram among Fig. 2;
Fig. 4 is the B place enlarged diagram of Fig. 2.
Among the figure: 1-main car frame, 2-driver's cab, 3-covering for roofs, 4-car body, 5-side wall, 6-partition.
The specific embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
Disclosed all features in this specification sheets, or the step in disclosed all methods or the process, except the speciality and/or step of mutual repulsion, all can make up by any way, unless special narration all can be replaced by other equivalences or the alternative features with similar purpose, namely, unless special narration, an embodiment in a series of equivalences of each feature or the similar characteristics.
As shown in Figure 1 and Figure 2, the utility model locomotive car body comprises main car frame 1 and car body 4, and described car body 4 comprises side wall 5, partition 6, driver's cab 2 and covering for roofs 3, is movable demountable structure between described car body 4 and the main car frame 1.
Specifically, bolt connects between described side wall 5 and the covering for roofs 3.
As another mode, described side wall 5 is the integral type structure with covering for roofs 3.
Described main car frame 1 and side wall 5 are for bolt is connected, and main car frame 1 is connected for bolt with driver's cab 2.
Embodiment 1:
When this locomotive is the inside corridor structure, the width of covering for roofs 3 is arranged to the width corresponding with plane on the main car frame 1, will form like this inside corridor formula locomotive as shown in Figure 3, Figure 4.
The connection mode of main car frame and car body is specially: plane one side is provided with boss near the outer edge place on the described main car frame 1, and the side wall bottom of car body 4 is provided with the Ka Tai corresponding with boss, and car body 4 is threaded with boss by Ka Tai and fixes with main car frame 1.
This connection mode can be used as main car frame and car body being connected of a car sidewall wherein, it also can be the connection mode of both sides, except this connection mode, main car frame and car body also can adopt following connection mode, namely, the edge, plane is provided with L shaped mat on side wall bottom and main car frame 1, and car body 4 is fixing by mat and main car frame 1.
When this locomotive need to be designed to the outside corridor structure, only need to select the covering for roofs less than plane width on the main car frame, by being connected of side wall and main car frame, just formed outside corridor like this.
In addition, each machine chamber of car body is designed to module, again side wall and main car frame is linked together, improved attainability, working service and the maintenance performance of locomotive.Adopt the car body of this structure, carrying out locomotive when always assembling, each equipment can be assembled at the platform of main car frame on the car, greatly strengthens the space availability ratio of locomotive assembling, has improved the manufacturability of locomotive, and maintenance is convenient.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
