The present embodiment in order to facilitate understanding below shrinks intersection expansion bracket by being deployed into, then is said to rollover states
It is bright:
As shown in Fig. 7 to Figure 15, cover device is unfolded state in figures 7 and 8, and two top cover units are jointly to loading space
Top is covered, and the outside of curb girder 700 is provided with sliding shifting block 600, corresponding to be also equipped on the curb girder 700 of the other side
One sliding shifting block 600.Loading space will drive cover device and be integrally moved to the left, be now placed in curb girder 700 when mobile towards left side
On sliding shifting block 600 can be abutted with collision head device 900, subsequent collision head device 900 drives sliding shifting block 600 to move, to make
Sprocket wheel where sliding shifting block 600 rotates, successively ipsilateral since two ipsilateral chain-wheel mechanisms are connected by gear assembly
Two chain-wheel mechanisms can run simultaneously and contrary, and since two retarders of top cover unit pass through intermediate biography
Moving axis links together, and therefore, four chain-wheel mechanisms on cover device can operate normally, and its respective intersection is driven to stretch
Contracting frame 100 is shunk.Fig. 9 and Figure 10 is the schematic diagram intersected when expansion bracket 100 is contracted to half, when loading space continues to Forward
When dynamic, sprocket wheel is continued to rotate, and can make to intersect the contraction completely of expansion bracket 100, the state that as Figure 11 and Figure 12 are shown.Loading space at this time
When continuing to move along, chain-wheel mechanism can drive rotating bar 410 to continue to rotate, since shackle rod 420 is moved into guiding
The end of 430 guide groove of part, shackle rod 420 can apply torque so as to hand over to guide part 430 and intersection expansion bracket 100 at this time
It pitches expansion bracket 100 and guide part 430 rotates, as shown in FIG. 13 to 15, until sliding shifting block 600 and corresponding collision head device
900 are detached from.In figures 14 and 15, intersect expansion bracket 100 to complete to overturn to the other side of transmission shaft 500, it in this way can be by goods
Compartment opening fully opens, and intersection 100 pairs of openings of expansion bracket is avoided to block, and cargo is facilitated to be packed into or remove.
As shown in figure 16, further embodiment of this invention provides a kind of rail vehicle, which includes loading space and top
Lid arrangement, the top of loading space have an opening, and cover device is cover device provided by the above embodiment, the cover device for pair
Opening is covered.
The cover device provided through this embodiment, may have the advantage that
1. the connecting rod intersected in expansion bracket is connected using pin shaft, block piece uses pin shaft to connect with expansion bracket is intersected, and hides
There is no any connection between block piece and block piece, is not in stuck phenomenon.Intersecting expansion bracket connection has rigidity big, supports energy
The strong feature of power further increases overall stiffness after connecting with block piece, has very strong bearing capacity.
2. the expanding-contracting action of top cover is driven using retarder, after chain stop motion, top cover is able to maintain in any position
Set fixation, when top cover is in full open position, even if dump truck overturn unloading when top cover be still able to maintain it is opposite with car body
Static state.
3. top cover is bilateral to opening structure, sliding shifting block is skew symmetry arrangement, therefore when loading space is forward and reverse and collision head device
Top cover can be opened and closed when contact.
4. the settable artificial interface using the tools such as mechanical wrench, wind spanner opening and closing top cover in the end of speed reducer, increases
The flexibility of top cover opening and closing, adaptability.
Turn 5. the on-off action of top cover is converted to transmission shaft by the linear movement of sliding shifting block, chain, sprocket wheel, retarder
It is dynamic, the telescopic and flipped of top cover can be made to act continuous.
6. the expanding-contracting action of top cover does not need slideway, the guide groove by guide part is the telescopic direction that can determine top cover.
7. two identical top covers of vehicle mirror-image arrangement, to make two top cover synchronization actions, an envelope is arranged in each top cover
Chain drive is closed, intermeshing tumbler gear is set at the sprocket wheel of middle part.To prevent chain from loosening, it is arranged in chain circle
Tensioner apparatus.
8. the way of contact of sliding shifting block can adapt to vehicle empty and load and wheel wear bring height change.
9. the structure type of block piece is simple and reliable, easy access maintenance replacement.
10. the present invention program can be applied to hopper wagon, open-top car can also be applied to, versatility is good.
