Description

A kind of rolling stock top cover switching mechanism

Technical field

The present invention relates to rolling stock technical field, specially a kind of rolling stock top cover switching mechanism.

Background technology

The rolling stock runed at present is gondola car mostly, and in blowing and raining, the loose goods that in-car loads are not only It is possible to impaired, and easily leaks out pollution surrounding enviroment.The existing lid vehicle that has is essentially all that operator climbs up Roof is opened and closed top cover, laborious time-consuming and dangerous, has only a few capping hopper wagon to be opened and closed top cover by pneumatic form, it is opened It is more complicated to close mechanism, cost is higher, reliability it is poor, it is necessary to blast it is higher.

The content of the invention

The present invention is mostly gondola car or has lid vehicle to be climbed up using operator to solve existing rolling stock The roof opening and closing mode such as top cover, material be present and drench with rain impaired, operation the problems such as wasting time and energy, there is provided a kind of rolling stock top cover is opened Close mechanism.

The present invention adopts the following technical scheme that realization:A kind of rolling stock top cover switching mechanism, including by driving machine Structure controls and stretches out car body through the rotating shaft in car body below top cover and the crank throw positioned at top cover both sides, rotating shaft both ends Both sides, crank throw one end are connected with rotating shaft, and the other end is hinged by round pin and top cover one end, and the top cover other end is provided with two top covers Roller, car body are provided with the roller track to be cooperated with top cover roller.

Described roller track is the broken line shape formed that joined end to end by some straightway tracks, to control top cover to roll The speed of wheel, and reach(When closing top cover)Labour-saving effect.

Described roller track end is provided with shoulder block, continues to roll to limit top cover roller, reaches reliable, safe effect Fruit.

Using the structure design of invention, the side of top cover is swung centered on rotating shaft, and opposite side is rolled by roller along track It is dynamic, reduce the frictional resistance that top cover is turned on and off;The Track desigh of top cover roller is into the rectilinear(-al) by different angle Broken line shape, to control the speed of top cover roller, reach labour-saving effect, track end is designed to shoulder block shape, to limit Top cover roller processed rolls, and reaches reliable, safe effect.

Compared with prior art, the present invention does not need operator to climb up roof opening and closing top cover, and simple in construction, operation saves Power, good reliability, cost is low, can be applied to various rolling stock and install top cover additional.

Brief description of the drawings

Fig. 1 is the front view of the present invention;

Fig. 2 is the top view of the present invention;

In figure:1- top covers;2- car bodies;3- rotating shafts;4- crank throws;5- round pins;6- top cover rollers;7- roller tracks;8- shoulder blocks.

Embodiment

A kind of rolling stock top cover switching mechanism, as shown in Figure 1, 2, including by driving mechanisms control and through top Car body both sides are stretched out at rotating shaft 3 in the lower section car body 2 of lid 1 and the crank throw 4 positioned at top cover both sides, rotating shaft both ends, crank throw one end with Rotating shaft is connected, and the other end is hinged by round pin 5 and top cover one end, and the top cover other end is provided with two top cover rollers 6, is set on car body There is the roller track 7 to be cooperated with top cover roller.Roller track 7 is the broken line formed that joined end to end by some straightway tracks Shape, the broken line shape of roller track are generally:Top cover opening procedure is formed for the upward slope section of different small slope angles, and top cover was closed Journey forms for the lower slope section of different small slope angles;The end of roller track 7 is provided with shoulder block 8.Drive mechanism can use cylinder, hydraulic cylinder or Motor drives.Crank throw moves in a circle all around rotating shaft during top cover opening and closing, and rotating shaft position and crank throw length should be able to meet Top cover opens or closes completely,

As shown in figure 1, bold portion represents that top cover is in closure state, when needing to open top cover, start driving structure, Rotating shaft rotation is driven, then crank throw is rotated, the crank throw other end drives top cover slowly to open, the top cover of top cover opposite side Roller slides along track, until shoulder block position, both cause top cover to open completely at collective effect, such as dotted portion in Fig. 1.

Claims (2)
