Abstract
The utility model relates to a transition hood of a railway vehicle cab. The transition hood structure in smooth transition installation and sealed connection with the external curved surface of a cab shell main body is additionally arranged without influencing the prior shell main body bearing structure of the cab, so as to improve the mounting reliability of the prior front opening/closing mechanism, reduce the unsmooth degree of the external curve surface of a cab head part caused by manufacturing and installation errors, and improve the overall appearance uniformity. The rear part of the transition hood is fixedly connected with the cab shell main body; an inward flanging structure is arranged at the connection part of the transition hood and the cab shell main body; a plurality of screw holes are formed on the flanging structure; and the transition hood is made of a material identical to that of a front opening/closing mechanism, such as glass fiber reinforced plastics, so as to ensure the sealing performance between the transition hood and the front opening/closing mechanism.
Description
Technical field
The utility model is a kind of transition head-shield of driver's cab, is applied to have the high-speed track vehicle driver's cab housing structure improvement of front end switching mechanism particularly, belongs to mechanical manufacturing field.
Background technology
The speed per hour of present domestic guideway vehicle has reached velocity stage more than 300 kilometers, therefore has higher requirement for the dynamics design of driver's cab head shell.The headstock of high-speed track vehicle all adopts airflow design, disposes the front end switching mechanism of split type automatic shutter for satisfying the user demand that connects extension between the vehicle.When vehicle normally moved, front end switching mechanism closure was to reduce air resistance.When needs connect other vehicles of extension separately, thereby the front end switching mechanism is opened the space of reserving necessity for hitch even extension.
The driver's cab head of existing high-speed track vehicle generally adopts the form of " housing main body+front end switching mechanism ".Because technological problemses such as the manufacturing of front end switching mechanism cover body, installation can form phenomenons such as appearance curved surface transition irregularity between switching mechanism cover body and the driver's cab housing main body, construction and maintenance inconvenience usually.
In addition, the driver's cab housing main body also adopts different materials with the front end switching mechanism, and this also is after just causing the front end switching mechanism to close, and housing main body and front end switching mechanism leave certain interval, close major cause is not closed completely.
The said structure defective can cause the driver's cab head to bleed air usually and form the air-negative-pressure zone, thus the head air resistance when increasing vehicle operating.
The utility model content
The transition head-shield of guideway vehicle driver's cab described in the utility model, be to address the above problem and on the basis of not destroying the existing housing main body carrying structure of driver's cab, increase by a transition head cover structure, to form transition installation, the airtight connection structure smooth-going with the housing main body appearance curved surface.
Design goal of the present utility model is, increase a transition installation, connection structure to improve the installation reliability of existing front end switching mechanism, reduction improves the unanimity of overall appearance moulding because of the uneven compliance of driver's cab head outward appearance curved surface that manufacturing, installation error cause.
Another design goal is, a kind of connection, closed structure of being convenient to front end switching mechanism dismounting maintenance is provided.
Design goal is that also the airtight performance when raising front end switching mechanism is closed reduces the air resistance that the driver's cab housing main body is subjected to effectively.
For realizing above-mentioned design goal, be increase by one transition head-shield between the housing main body of the driver's cab head of existing high-speed track vehicle and front end switching mechanism, the rear portion of this transition head-shield and driver's cab housing main body are fastenedly connected.
The connecting portion of transition head-shield and driver's cab housing main body is provided with inside turnup structure, and turnup structure is provided with several screws.
As above-mentioned basic scheme, the rear portion of transition head-shield and driver's cab housing main body adopt the mounting means that is spirally connected.
For guaranteeing and the airtight performance of front end switching mechanism that described transition head-shield adopts the material identical with the front end switching mechanism, as adopting glass-reinforced plastic material.
For the rigidity intensity that further improves described transition head-shield and with the outward appearance curved surface harmony of driver's cab housing main body, can take following improvement project:
The transition head-shield is by the stamping forming integral structure of integral body, and has the outer surface profilograph identical with the driver's cab housing main body.
The transition head-shield adopts integral forming technique, carry out the design of local moulding according to requirement of strength, thereby fully take into account manufacturing, installation error, and and housing main body between the smooth-going degree of outward appearance curved surface.
The width of described transition head-shield is not a certain value, can be optimized selection according to the head-shield size of front end switching mechanism.
For optimizing coordination performance is installed,, is provided with bearing cap shim at the turnup structure of described transition head-shield and the bolted connection place between the driver's cab housing main body.
For increase with driver's cab head shell main body between be connected tightness, at the turnup structure of described transition head-shield and the bolted connection place between the driver's cab housing main body, be coated with adhesives and body solder.
As mentioned above, the transition head-shield of the utility model guideway vehicle driver's cab has following advantage and beneficial effect:
1, by the transition installation and the connection structure of increase, improve the installation reliability of front end switching mechanism effectively, reduce the uneven compliance of the driver's cab head outward appearance curved surface that causes because of manufacturing, installation error, improve the unanimity of overall appearance moulding.
2, be convenient to connection, the closed structure of front end switching mechanism dismounting maintenance.Such as, run into the damage that collision waits the switching cover body that unforeseen circumstances causes, when but driver's cab housing main body structure is not damaged, behind the promptly detachable transition head cover switching mechanism is checked or directly changed corresponding damage parts, thereby improved front end switching mechanism maintainability.
Airtight performance when 3, improving the front end switching mechanism and close effectively reduces the air resistance of driver's cab housing main body.
4, do not destroy the carrying structure of existing driver's cab housing main body, guarantee its mechanical strength, and simple in structure, anufacturability is strong.
