Abstract
The invention belongs to the technical field of parts for railway freight wagons, in particular to a sealing structure for a bottom door of a hopper wagon, which solves the problems that the bottom door of the conventional railway freight wagon cannot meet requirements of sealing and safe transportation of materials with larger stack density and smaller particles. In the sealing structure, the lower end of a middle hopper plate of the hopper wagon is beveled downwards; the upper end of a flow ballast plate is beveled upwards; the beveled angles of the middle hopper plate and the flow ballast plate are welded together in a staggered manner; a box-shaped structure is formed between the welded parts of the flow ballast plate and the middle hopper plate; the beveled angle of the middle hopper plate and a bottom door wrapping plate are sealed firstly; the flow ballast plate and the bottom door wrapping plate are tightly attached to be sealed secondarily; a labyrinth-type sealing structure between the bottom door and a hopper discharging opening is formed by first seal and second seal; and flow guide plates are arranged at all corners of the hopper discharging opening formed by a side hopper plate, a hopper partition plate, the middle hopper plate and the bottom door wrapping plate. The sealing structure for the bottom door of the hopper wagon has the advantages that: the sealing effect of the discharging opening is enhanced; safe transportation of cargoes such as iron ores with larger stack density and smaller particles can be realized; and the long-time use stability of vehicles can be improved.
Description
Technical field
The invention belongs to the technical field of railway truck, be specifically related to a kind of hopper car bottom door hermetically-sealed construction with parts.
Background technology
Mainly contain the hopper car of shipment grain, ore, coal, the stone tiny fragments of stone, coal, etc., cement in the domestic railway truck hopper car series.Grain and cement hopper car adopt central funnel unloading mode, and lural sealing means is flat closure plate structure, and closure plate and bell mouth seal through rubber pad.Adopt the hopper car negligible amounts of this kind sealing means, the cement hopper car makes progressively to have been replaced the unloading difficulty by the bulk cement carrier of wind-force unloading also owing to problems such as cement harden.The main hopper car of the large bulk freight of Chinese Transport is ore, coal, stone tiny fragments of stone, coal, etc. hopper car, and the applicant is designed with vehicles such as K13 type stone tiny fragments of stone, coal, etc. hopper car, K18 moulded coal charcoal hopper car, K13B type limestone hopper car respectively according to the characteristic of loose goods.These several kinds of hopper cars adopt the bell mouth of both sides unloading, and the sealing of goods realizes through closing of movable bottom door.Just because of the influence of bottom door opening and closing, (general gap is 10mm ~ 15mm), for the big thermal coal of the bigger stone tiny fragments of stone, coal, etc. of particle and viscosity, can also satisfy seal request like this between bottom door and bell mouth, to have bigger gap.(particle is 5 mm ~ 10mm), because iron ore viscosity is little, so the funnel of this several kinds of vehicles, bottom door hermetically-sealed construction obviously do not have sealing function to make steel required a large amount of shot iron ore for steel mill.
Summary of the invention
The present invention can not satisfy the sealing of the big and less material of particle of bulk density and transport problem safely in order to solve existing railway truck hopper car bottom door, and a kind of hopper car bottom door hermetically-sealed construction is provided.
The present invention adopts following technical scheme to realize:
A kind of hopper car bottom door hermetically-sealed construction; The lower ends downward knuckle that it is characterized in that the middle funnel plate of hopper car; The welding that offsets of the upper end of the stream tiny fragments of stone, coal, etc. plate knuckle that makes progress, the knuckle of middle funnel plate and stream tiny fragments of stone, coal, etc. plate forms box type construction between stream tiny fragments of stone, coal, etc. plate and the middle funnel plate weld; The knuckle of middle funnel plate and bottom door wrapper sheet form once sealing; Stream tiny fragments of stone, coal, etc. plate and bottom door wrapper sheet are adjacent to the formation secondary seal, and once sealing and secondary seal constitute the labyrinth seal structure between bottom door and the funnel discharging hatch, and each corner of the funnel discharging hatch that side leakage strickle, funnel dividing plate, middle funnel plate and bottom door wrapper sheet form is provided with deflecting plate.Deflecting plate adopts accurate blanking and die mould, plays sealing function with bottom door and other structure.
Another preferred version of the present invention: bottom door is set up the grooved gusset at the back.
The relative prior art of the present invention has following beneficial effect:
1, the use of new bottom door hermetically-sealed construction has improved the sealing effectiveness of discharging hatch, can satisfy the cargo security transportations that bulk density is big and particle is less such as iron ore.
2, stream tiny fragments of stone, coal, etc. plate and middle funnel plate box-structure design has improved lural strength and stiffness, and the strength and stiffness of stream tiny fragments of stone, coal, etc. plate and middle funnel plate.Existing packaging technology has been satisfied in the design of bell mouth position while welding, pattern, has improved welding quality.This bell mouth simultaneously can improve the stability of vehicle long-term use.
3, maximized employing existing structure characteristics, little to the packaging technology influence of existing vehicle, production efficiency is constant, and assembling, welding quality can be improved.Can satisfy simultaneously existing daily utilization, maintenance and overhauling system.
Description of drawings
Fig. 1 is a structural representation of the present invention
Fig. 2 is the partial enlarged drawing of Fig. 1
Among the figure: 1-divides Zha Liang, 2-side leakage strickle, 3-bottom door, 4-bottom door wrapper sheet, 5-funnel dividing plate, 6-stream tiny fragments of stone, coal, etc. plate, 7-stiffener angle, funnel plate among the 8-, 9-deflecting plate.
The specific embodiment
Be described further in conjunction with the accompanying drawing specific embodiments of the invention.
The present invention strengthens, strengthens the branch tiny fragments of stone, coal, etc. beam 1 in the funnel, reduces goods bottom door (is seen Fig. 1: pressure piece number 3).Middle funnel plate 8 bottoms increase an angle steel 7, the rigidity of funnel plate in the raising.To flow tiny fragments of stone, coal, etc. plate 6 knuckles and middle funnel plate 8 knuckles offsetting welding, and form a box-structure at stream tiny fragments of stone, coal, etc. plate 6 and 8 of middle funnel plates, and improve lural strength and stiffness, the strength and stiffness that flow tiny fragments of stone, coal, etc. plate and middle funnel plate simultaneously also are improved.And this lural design can adopt welding machine special concerning welding process, makes the weld seam one-shot forming to improve welding quality.
Bottom door has increased grooved gusset 2 for improving its rigidity and intensity at the back at bottom door, and bottom door folding and bottom door wrapper sheet 4 thickness increase 1mm.
Be designed to labyrinth seal structure between bottom door and the funnel discharging hatch; The knuckle limit of funnel plate and bottom door wrapper sheet form the long seal clearance of 60mm in the utilization; When bottom door is in closed condition; Knuckle and bottom door wrapper sheet through middle funnel plate form once sealing, and the bottom door wrapper sheet is adjacent to the formation secondary seal with stream tiny fragments of stone, coal, etc. plate.Loose goods at bottom door and bell mouth gap location because the variation of loading angle, make flow out goods in first seals at insufficient pressure promoting the goods of gap location, thereby play sealing function.This structure can adopt existing frock, technology, and the gap of bottom door be also easy to control so that bottom door and bell mouth have certain clearance.In funnel dividing plate 5 and bell mouth place die mould deflecting plate 9 is set, reduces the possibility that goods flows out from the bottom door side.
