Description
Technical field
The invention belongs to coal hopper car water-tight equipment technical field, specifically a kind of sealed hopper wagon bottom door.
Background technology
The bottom door structure of domestic existing coal hopper car and some other hopper wagon is basically identical.To ensure that bottom door locking can
Lean on, there must be certain gap between bottom door upper door frame and curb girder, between bottom door lower edge and funnel plate and bottom door both sides and funnel end
Also there must be certain gap between plate.Gap can infilter sleet, be possible to when hopper wagon transport needs the goods of moistureproof and waterproof
Attacked by sleet；Gap between gap and bottom door both sides and funnel end plate easily leaks goods.All it is in the past from manufacturing process
Reduce these gaps as far as possible, but can not fundamentally solve the above problems.
The content of the invention
The present invention easily leaks asking for goods to solve the gap between hopper wagon gap and bottom door both sides and funnel end plate
There is provided a kind of sealed hopper wagon bottom door for topic.
The present invention takes following technical scheme：A kind of sealed hopper wagon bottom door, including curb girder, bottom door folding, upper door frame,
It is provided with and visits in door-plate, door bottom girder, V-seal bar, funnel plate and hopper wagon bottom door lower seal structure, bottom door folding
Frame, is provided with V-seal bar, upper door frame between upper door frame and curb girder and is provided with door-plate, and door-plate side is provided with door bottom girder, door bottom girder
Bottom is provided with hopper wagon bottom door lower seal structure, and described hopper wagon bottom door lower seal structure includes passing through nut and pressing plate
The funnel plate of sealing gasket on door-plate, sealing gasket side and lower section is tightly connected.
Further, the material of V-seal bar is elasticity is good and wear resistant corrosion resistant rubber, its natural subtended angle can for 40 °~
60°。
Further, the material of sealing gasket is wear resistant corrosion resistant rubber, and pressing plate is provided with some mounting holes being arranged side by side,
Mounting hole is elongated hole, the adjustment amount having along elongated hole direction.
Compared with prior art, the present invention effectively improves bottom door sealing by V-seal bar and adjustable sealing gasket
Property, existing hopper wagon bottom door is solved because of structure gap, and caused sleet penetrates into, cargo leakage inertia problem.With structure letter
Single, low cost, easy access is changed, and efficiently solves the inertia problem of coal hopper car and other hopper wagon bottom doors sealing difference.

Embodiment
To make the technical problem to be solved in the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and tool
Body embodiment is described in detail.
As shown in Figure 1, 2, a kind of sealed hopper wagon bottom door, including curb girder 1, bottom door folding 2, upper door frame 3, door-plate 4, door
Upper door frame 3 is installed in bottom girder 5, V-seal bar 6, funnel plate 9 and hopper wagon bottom door lower seal structure, bottom door folding 2,
It is provided between upper door frame 3 and curb girder 1 on V-seal bar 6, upper door frame 3 and door-plate 4 is installed, the side of door-plate 4 is provided with door bottom girder 5, door
The bottom of bottom girder 5 is provided with hopper wagon bottom door lower seal structure.As shown in figure 4, described hopper wagon bottom door lower seal structure bag
Include the sealing gasket 7 being arranged on by nut 10 and pressing plate 8 on door-plate 4, the funnel plate 9 of the side of sealing gasket 7 and lower section is tightly connected.
Referring to Fig. 3, the material of V-seal bar 6 for elasticity is good and wear resistant corrosion resistant rubber, its natural subtended angle can for 40 °~
60°.V-seal bar can be directly bonded on curb girder by seccotine or is fastened on pressing plate, bolt and nut on curb girder, and V-type is close
Strip of paper used for sealing must have certain pre compressed magnitude when assembling, to ensure that bottom door can keep sealing during opening or closing.
Referring to Fig. 5, the material of sealing gasket is wear resistant corrosion resistant rubber, and pressing plate 8 is provided with some mounting holes being arranged side by side
11, mounting hole is elongated hole, the adjustment amount having along elongated hole direction.The gap of bottom door lower edge and funnel plate is eliminated or reduced with this,
Its gap is 1.5mm to the maximum.The sealing of bottom door both sides and funnel end plate is similarly.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, on the premise of principle of the present invention is not departed from, some improvements and modifications can also be made, these improvements and modifications
It should be regarded as protection scope of the present invention.
