Description

The sealing arrangement of railroad hopper lorry car door

The utility model relates to a kind of sealing arrangement of industrial and mineral railway truck car door, is specially adapted to the sealing arrangement of hopper car car door.

At present the railway sealing arrangement that is used to transport bulk material hopper car car doors such as lime, coal, sintering breeze mostly adopts and adds the rubber plate sealing in the doorframe inboard, also have and adopt at funnel soleplate edge stainless steel sheet, and on door, add sharp-pointed structures such as closing plate, but the sealing effectiveness of above-mentioned several structures is even unreliable, rubber plate sealing not only the having increased resistance of closing the door, and rubber is easily aging damaged, causes sealing effectiveness not good, loses sealing function even.Not only increased the installation and maintenance expense of vehicle at funnel soleplate edge stainless steel sheet, and sharp-pointed closing plate then produces the gap inevitably with the assemblage gap of funnel soleplate and the distortion of sharp-pointed closing plate, leak the still not solution of material phenomenon.

The purpose of this utility model provides a kind of simple in structure, but the crack between a door and its frame automatic seal is tight during closing of the door, no-leak goods during driving, and behind the car door opening, sealing arrangement can not influence the sealing arrangement of the railroad hopper car door that goods draws off.

The utility model is to realize like this, it is by car door, funnel soleplate, the funnel end plate is formed, it is characterized in that the control angle bar being set in the both sides, bottom of funnel soleplate, bottom at funnel soleplate is provided with folding, the folding seat, control angle bar and folding are welded on the bent plate, the folding seat is welded on the angle bar below the funnel soleplate, on the folding seat, have the bearing pin circular hole, in control angle bar and folding, also have the bearing pin circular hole, and the three hingedly is installed in the two ends, bottom of funnel soleplate by bearing pin, the midway location of angle bar welds 2～3 double spread seats equably below funnel soleplate, and folding is through in the folding seat by bearing pin, is welded with two gussets on the angle bar of the both sides, bottom of car door, one end of block is welded on the gusset, horizontal baffle is welded on the bottom of car door, and connects with brace panel, in the installed inside of funnel end plate end-stopping plate is arranged.

The utility model has the advantages that sealing is tight reliable, and is simple in structure, makes easy to maintenancely, during the shipment bulk material, when especially transporting the bulk material of 3～5mm, can prevent effectively that material from sewing from car door stitches.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the structural representation of the front view of the utility model door sealing device.

Fig. 2 is that the utility model door sealing device is in sealing state scheme drawing at closing time.

Fig. 3 is the control angle bar of the utility model door sealing device and the view that block begins contact point.

Fig. 4 is the A-A section side door seam sealed structural representation of the utility model door sealing set-up diagram 2.

Referring to Fig. 1,2, the sealing arrangement of railroad hopper lorry car door of the present utility model, be by car door, funnel soleplate, the funnel end plate is formed, its main points are that the lower side two at funnel soleplate 4 is provided with control angle bar 3, be provided with folding 5 in the bottom of funnel soleplate 4, folding seat 6, control angle bar 3 and folding 5 are welded on the bent plate 8, make it to constitute a drop in leaf, folding seat 6 is welded on the angle bar 14 below the funnel soleplate 4, on folding seat 6, have the bearing pin circular hole, in control angle bar 3 and folding 5, also have the bearing pin circular hole, and the three hingedly is installed in the two ends, bottom of funnel soleplate 4 by bearing pin 7, the midway location of angle bar 14 welds 2～3 double spread seats 6 equably below funnel soleplate 4, folding 5 is through in the folding seat 6 by bearing pin 7, make by bent plate 8, control angle bar 3, the drop in leaf that folding 5 constitutes can be around round pin axle 7 rotations of 6 li of folding seats, on the angle bar 15 of the both sides, bottom of car door 1, be welded with two gussets 11, block 2 is welded on the gusset 11, horizontal baffle 9 is welded on the bottom of car door 1, and connect with brace panel 10, after railway carriage loading at closing time, car door 1 is at the effect lower edge of external force door-hinge left-hand revolution, the inclined-plane of the control angle bar 3 on block 2 and the drop in leaf contacts (referring to Fig. 3), when door 1 continues when door-hinge rotates, block 2 promote control angle bar 3 make it around bearing pin 7 by clickwise, until the position of closing the door fully, this moment, bent plate 8 was horizontal with the closed surface of horizontal baffle 9, the horizontal closed surface of material impassabitity flows out like this, thereby the crack between a door and its frame gap, lower edge of car door 1 is sealed, in order to make the side door gap sealing, the utility model also has end-stopping plate 12 in the installed inside of funnel end plate 13, referring to Fig. 4, adopt end-stopping plate 12, stopped that effectively material sews from the side, play a part having arrived the sealing side door.When opening the door since the effect that door is subjected to external force around door-hinge by clickwise, drop in leaf when door is in door opening state, is controlled angle bar 3 half-twists also because action of gravity is pressed left-hand revolution around pivot pin 7, bent plate 8 is in vertical position, and does not draw off so sealing arrangement can not influence goods.
