Description
Technical Field
The utility model belongs to the technical field of the boxcar improves, concretely relates to automatic door opening mechanism of boxcar.
Background
At present, the automatic mechanism of opening door of normal boxcar, it is taut to all lean on hydraulic telescoping device's pulling force with the carriage when the carriage door is closed, the carriage door is lifted and is pushed up the door by hydraulic telescoping device's reasoning, but when transporting some heavier article of self weight, the carriage door is probably opened by oneself under the effect of article self weight, there is the phenomenon that goods oneself falls down, in order to prevent the appearance of this type of phenomenon, generally install lock lever mechanism on the carriage door among the prior art, lock lever mechanism all needs manual operation when opening or closing, so can and inconvenient at the in-process that uses, for this reason, we propose an automatic mechanism of opening door of boxcar.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an aim at above-mentioned prior art current situation, propose to exist on the prior art not enough, provide an automatic mechanism of opening door in boxcar.
In order to realize the purpose, the utility model discloses specifically adopt following technical scheme:
the utility model provides an automatic mechanism of opening door of boxcar, includes carriage 1, supporting shoe 2, railway carriage or compartment door 3, supporting shoe 2 be located the left side in carriage, supporting shoe 2 fixes in carriage 1's the outside, the right side of supporting shoe 2 is equipped with waist shape connecting block, the inboard of connecting block is equipped with hydraulic telescoping device 10, hydraulic telescoping device 10 is articulated with the connecting block, its characterized in that: the top of carriage 1 is equipped with railway carriage or compartment door hoist mechanism 8, and the second connecting piece 11 that the right-hand member of railway carriage or compartment door hoist mechanism 8 and 1 upper portion in carriage were equipped with is articulated, and the left side of railway carriage or compartment door hoist mechanism 8 is articulated with the top of railway carriage or compartment door 3, and the top of hydraulic telescoping device 10 is articulated with first connecting piece 9 that the railway carriage or compartment door hoist mechanism 8 bottom was equipped with.
Furthermore, the left side and the right side of the compartment door 3 are symmetrically provided with driving blocks 6, and the driving blocks 6 are fixed on the upper part of the compartment door 3.
Further, a gap 7 is reserved between the bottom of the lifting mechanism 8 and the right side of the driving block 6.
Furthermore, the left side and the right side of the compartment door 3 are symmetrically provided with first wedge-shaped fixture blocks 5.
Furthermore, the left side and the right side of the supporting block 2 are provided with second wedge-shaped fixture blocks 4, and the second wedge-shaped fixture blocks 4 are matched with the first wedge-shaped fixture blocks 5.
Compared with the prior art, the beneficial effects of the utility model reside in that: the hidden hinge structure of the dangerous chemical van vehicle has the advantages that the top surface of the hidden handle 11 is lower than the upper surface of the box body 1, the hidden handle 11 is not easily interfered by external force to open, and the transportation safety of dangerous chemicals is guaranteed; in addition, the hidden handle 11 that hinge structure was hidden to danger article van was equipped with makes the railway carriage or compartment door 2 of opening comparatively convenient with the cooperation of hiding lock thick stick fixed block 4 to the second.
Compared with the prior art, the beneficial effects of the utility model reside in that: the utility model provides a freight train carriage automatic door opening mechanism need not lock lever mechanism and also need not manual operation can accomplish opening and shutting of railway carriage or compartment door in operation process, and the design of second wedge fixture block 4 and first wedge fixture block 5 makes railway carriage or compartment door 3 and the inseparable laminating of supporting shoe 2 be in the same place, has guaranteed that the railway carriage or compartment door can not oneself open.
Drawings
Fig. 1 is a schematic structural view of the box 1 and the car door 3 of the present invention.
In the figure: carriage 1, supporting shoe 2, railway carriage or compartment door 3, second wedge fixture block 4, first wedge fixture block 5, drive block 6, clearance 7, railway carriage or compartment door hoist mechanism 8, first connecting piece 9 is articulated, hydraulic telescoping device 10, second connecting piece 11 is articulated.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Example 1
