Description
Technical field
The utility model relates to tramway train construction applications, a kind of tramway train front shroud opening and closing structure.
Background technology
Existing front shroud opening and closing is all research object with motor train unit, front shroud is divided into two pieces, left and right, front shroud unfolding mode is opened about in horizontal surface, because motor train unit front end narrow space is not accessible and the feature such as the opening direction of cover plate, existing front shroud opening and closing all have employed propulsions source such as pushing cylinder.
And for the tramway train of middle low speed, radius of curve is less, hitch in horizontal surface and vertical plane all have comparatively big swing angle, and then require the overall lifting of front shroud.
Therefore, realize the overall rapid uplift of tramway train front shroud, and can be in stabilized conditions after lifting, be this area technical barrier urgently to be resolved hurrily.
Utility model content
The feature such as lower for tramway train floor level, front shroud is accessible, the utility model aims to provide a kind of tramway train front shroud opening and closing structure, this opening and closing structure adopts the mode of manual unlocking, without the need to extra power source, and structure is simple, practical function, stable performance.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of tramway train front shroud opening and closing structure, its constructional feature is, described front shroud is contained on car body by least one group of four-bar linkage in vertical plane surface.
Described vertical plane surface refers to that the path of motion of four-bar linkage is perpendicular to horizontal surface, and thus, operator is front shroud upwardly, and the described car body of four-bar linkage on car body does vertical motion and open front shroud.
Be below the technical scheme of further improvement of the utility model:
As a kind of concrete version, described four-bar linkage comprises the permanent seat be fixed on car body, one end is hinged on the first rotating arm of permanent seat lower end, one end is hinged on the second pivot arm of permanent seat upper end, the other end of this first rotating arm and one end of a connecting arm are hinged and connected, the other end of this connecting arm and the other end of the second pivot arm are hinged and connected, and make permanent seat, first rotating arm, connecting arm and the second pivot arm form four-bar linkage; The connecting panel be fixedly linked with front shroud the connecting arm of described first rotating arm and connecting arm junction is equipped with.
Open to make front shroud when putting in place and keep fixing, described permanent seat is equipped with the locking device of the locking first rotating arm when front shroud is opened completely.
Exert a force to prevent operator and excessively cause failsafety, described permanent seat is equipped with shock absorber.
In order to prevent front shroud from opening excessively, described permanent seat being equipped with and preventing first rotating arm or the second pivot arm from rotating excessive inhibiting device.
Preferably, the four-bar linkage of two cover same structures described front shroud is equipped with, the two cover four-bar linkages with lateral clearance are arranged in same level and two cover four-bar linkages are arranged symmetrically with about car body line of centers, thus, can ensure Joint strenght and the stability of front shroud.
Further, described first rotating arm and the second pivot arm are bending part, and two pivot arms are oppositely arranged, and the line keeping parallelism quadrangle of each hinge-point, thus form similar hexagonal structure.
Above structure, the utility model has filled up the blank of tramway train integral type front shroud unfolding mode, adopts manual mode, without the need to extra power source, simple and practical, makes the overall lifting in vertical plane of cover plate, and is in stabilized conditions.
For making the overall lifting in vertical plane of cover plate, adopt two cover parallel four-bar linkages, Liang Tao mechanism is symmetrical about car body line of centers, and ensures that Mei Tao mechanism only has one degree of freedom, when manually applying pulling force to cover plate, connecting rod mechanism and integral type cover plate have well-determined path of motion.The connecting panel, inhibiting device, locking device, shock absorber etc. of two cover connecting rod mechanisms and integral type cover plate, connecting rod mechanism and an integral type cover plate constitute the switching mechanism of complete set jointly.As shown in Figure 1.
Often overlap parallel―ordinal shift structure to be made up of a permanent seat, two pivot arms and a connecting arm 4.Its schematic diagram as shown in Figure 3.
Integral type front shroud is applied to the power of any direction, this power can be delivered to the connecting arm 4 shown in accompanying drawing 2, then four-bar linkage starts to rotate around attachment point.As shown in Figure 4.At an arbitrary position, connecting arm 4 is all parallel with initial position (A position).When first rotating arm 2 and the second pivot arm 3 go to level attitude (C position), integral type front shroud is in foremost.When pivot arm continues motion, pivot arm and connecting arm 4 will reach coUinear state.Pivoted arm continues motion, and four-bar mechanism movement position is as shown in E position.
Consider engineering practicability, when cover plate reaches D position, connecting rod mechanism is in locking states, and front shroud is in settling position.
Compared with prior art, the beneficial effects of the utility model are: opening and closing structure of the present utility model effectively can support front shroud and front shroud is moved along particular track, and by front shroud rapid uplift in vertical plane, ensure train rescuing or when heavily joining, connecting rod mechanism is in locking states, and front shroud is in ad-hoc location.Simultaneously because front shroud is easy to close, adopt manual mode, without the need to extra power source, make integral type cover plate be in ad-hoc location.
Below in conjunction with drawings and Examples, the utility model is further elaborated.
