Abstract
The invention discloses a bottom door device of a railway freight car. The bottom door device comprises a gravity action type bottom door plate, and is characterized in that a rigid frame is fixedly mounted on the periphery of the lower edge of a funnel mouth of the railway freight car, a groove is arranged on the rigid frame, an opening of the groove is downward, a sealing strip is mounted in the groove, the sealing strip comprises a head part and a body part, the head part is embedded into the groove, and the body part extends out of the groove. The bottom door device disclosed by the invention can not only overcome the defects of poor sealing performance of a gravity action type bottom door and large impact during opening and closing of the bottom door, but also overcome the defects of poor bearing performance of the bottom door and incapability of realizing mechanical self-locking of an existing drawing plate type bottom door, has good transportation sealing property and reliability, and can meet the requirements of sealing in transportation of powdered and bulk cargoes, effectively reduce the leakage quantity of the cargoes and realize broad application prospects.
Description
Technical field
The invention belongs to the technical field of railway truck, be specifically related to a kind of railway truck bottom door device with parts.
Background technology
The bottom door and the switching mechanism of traditional railway truck are various informative; Mainly contain following two kinds of forms: a kind of is pumping board formula bottom door; Be applicable to that it is that the bottom door load-carrying properties are poor that grain, cement etc. require good sealing performance powdered goods, its shortcoming, can not realize mechanical self-latching.Second kind is action of gravity formula bottom door, and its shortcoming is a poor sealing performance, and the switch door is prone to produce greater impact.
Summary of the invention
Technical matters to be solved by this invention has provided a kind of railway truck bottom door device, overcomes above-mentioned two kinds of existing in prior technology defectives and deficiency.
For solving the problems of the technologies described above, the basic fundamental design that the present invention taked is on the basis of existing action of gravity formula bottom door, increases sealing arrangement.One of its technical scheme is: a kind of railway truck bottom door device, comprise action of gravity formula bottom door plate, and it is characterized in that; Fixedly mount rigid frame around the bell mouth lower edge of said railway truck, said rigid frame is provided with groove, and Open Side Down for said groove; Sealing band is installed in the said groove; Said sealing band comprises head, body two parts, and said head embeds in the said groove, and said body portion stretches out outside the said groove.
Further, said sealing band body cross section is a hollow structure.
Preferred, the cross-sectional plane of said groove is a dovetail form, and the cross-sectional plane of said sealing band head also is a dovetail form.
Also preferred, said sealing band head cross-sectional plane is a hollow structure.
Based on same technical conceive, two of technical scheme is: the railway truck bottom door device comprises action of gravity formula bottom door plate; It is characterized in that fixedly mount rigid frame on said bottom door plate and the one side that bell mouth contacts, said rigid frame is provided with groove; The opening of said groove is upwards installed sealing band in the said groove, said sealing band comprises head, body two parts; Said head embeds in the said groove, and said body portion stretches out outside the said groove.
Further, said sealing band body cross section is a hollow structure.
Preferred, the cross-sectional plane of said groove is a dovetail form, and the cross-sectional plane of said sealing band head also is a dovetail form.
Also preferred, said sealing band head cross-sectional plane is a hollow structure.
Technique scheme one, two relatively because action of gravity formula bottom door plate often is in the state of moving up and down, rigid frame be installed on the bottom door plate than being installed in the bell mouth, be subject to the deformation or the change in displacement influence of bottom door plate.Therefore, scheme one is more excellent solution.
The present invention had both overcome action of gravity formula bottom door poor sealing performance, the defective that the bottom door switching surge is big.The bottom door load-carrying properties that overcome simultaneously existing pumping board formula bottom door existence again are poor, can not realize the defective of mechanical self-latching.Possess good shipping seal property and reliability, can satisfy the needs of the shipping seal property of powdery, bulk freight, effectively reduce the spillage of goods, have broad application prospects.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment technical scheme of the present invention is further specified.
Fig. 1 is the structural representation of technical scheme one of the present invention.
Fig. 2 is the concrete structure figure for circular thin portion among Fig. 1.
Fig. 3 is a kind of instance schematic configuration diagram of sealing band of the present invention.
Fig. 4 is the embodiment constructional drawing of a kind of " well " shape misconstruction of rigid frame of the present invention.
Fig. 5 is the embodiment constructional drawing of a kind of docking structure of falling the 45 of rigid frame of the present invention.
The specific embodiment
Like Fig. 1, shown in Figure 2, fixedly mount rigid frame around bell mouth 4 lower edges, rigid frame is a channel doorframe 2.According to the sealing effectiveness needs, between bottom door plate 3 and bell mouth 4, reserve the gap of mounting groove iron doorframe 2 and sealing band 1.Channel doorframe 2 is provided with groove, and Open Side Down for groove, and sealing band is installed in the groove.As shown in Figure 3, sealing band comprises 5, body 6 two parts, and head 5 embeds in the grooves, and body portion 6 stretches out outside the groove.For keeping the closely connected of sealing band 1 and bottom door plate 3, increase the sealing effectiveness of bottom door plate, sealing band body cross section is a hollow structure.
For and assurance easy for installation with the channel doorframe are used reliable; The cross-sectional plane of groove is a dovetail form; The cross-sectional plane of sealing band head 5 also is dovetail form and is hollow structure that like Fig. 4, Fig. 5, the channel doorframe can be according to lural shaped design; Like bell mouth is the quadrangle that quadrangle can be designed to cooperate, if circle is circle; For ease of sealing band is installed, channel doorframe bight should be designed to " well " shape misconstruction or the docking structure of falling the 45; The channel doorframe is installed in the bell mouth, can adopt welding or riveted structure according to the needs of reality; The disconnected cross section of channel doorframe trench design becomes and the sealing band top respective outer side edges of falling dovetail shape; When sealing band is installed, can earlier the channel doorframe be advanced in one side pressure of sealing band top, through the opposite side at extruding top, make the distortion of sealing band top, reach pack into the fully groove of channel doorframe of sealing band top.
Because technical scheme two only is that with the difference of technical scheme one the channel doorframe is installed in the bottom door plate, those skilled in the art can make much of, so repeat no more.
The present invention had both overcome action of gravity formula bottom door poor sealing performance, the defective that the bottom door switching surge is big.The bottom door load-carrying properties that overcome simultaneously existing pumping board formula bottom door existence again are poor, can not realize the defective of mechanical self-latching.According to concrete railway truck bottom door structure design, extend to the transformation of corresponding vehicle bottom door closed type, have broad application prospects.
It should be noted last that; The above specific embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although with reference to preferred embodiment the present invention is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention; And not breaking away from the spirit and the scope of technical scheme of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
