The direction opposite with vehicle heading is slided, and then by the 3rd chain 46 link block 78 is driven to move to the left, link block
78 drive connecting rods composition 30 and are moved to the left simultaneously with the pulley assemblies 60 that connecting rod composition 30 is connected, and then open and be somebody's turn to do
The cap assembly 10 of 30 connection of connecting rod composition；Wherein, it is sliding during the left side in above-mentioned pulley assembly 60 into Figure 10 moves
Wheel assembly 60 drives the second chain 45 connected to it to left movement, so as to which the second chain 45 drives 42 turns of the second driven gear
Dynamic, the first driven gear 41 that the drive of the second driven gear engages setting rotates, and the first driven gear 41 is rotated so as to band
Dynamic the first chain 44 that setting is engaged with the first driven gear 41 moves right, the first chain 44 drive it is connected to it another
Pulley assembly 60 moves right so that another cap assembly 10 is also opened, in this way, the cap assembly 10 of opposite side is in the first chain
It is synchronously opened under the mating reaction of 44 and second chain 45 of item and gear structure.Two cap assemblies 10 are driven when fully opening
Mechanism is as shown in figure 11.After two cap assemblies 10 fully open, link block 78 is subject to backstop action stop motion, and first meets and discusses
The contact surface lower part of 76 and first sliding block 74 of device is equipped with spring, and the effect of the first sliding block 74 is subject to be risen again after compressing, under
When one vehicle drives to corresponding position, the first collision head device 76 contacts again with the first sliding block 74 set on next vehicle, weight
Double action is made, and after permutation vehicle after, the first collision head device 76 is packed up, and does not influence other rolling stocks.
After loading, vehicle continues to travel, and when the second sliding block 75 is contacted with the second collision head device 77, makes the second sliding block
75 slide along the 3rd track 73 to vehicle heading opposite direction, and then link block 78 is driven to move right, remaining action
Direction when being opened with head cover is on the contrary, drive two cap assemblies 10 to completely close, transmission mechanism is as shown in Figure 10 after closing.
In a second embodiment, using components such as the first sliding block 74, the second sliding block 75 and the 3rd chains 46 instead of
Drive motor and driving gear 43 in one embodiment remain the first driven gear 41, the second driven gear 42, the first chain
44 and second chain 45 and its matching relationship with other component.And the first collision head device 76 and the second collision head device 77 are the
One sliding block 74 and the second sliding block 75 are provided along lorry travel direction opposite effect power, the 3rd chain 46 are driven, so as to drive
Connecting rod composition 30 moves to the left.The second driven gear 42 at this time becomes the driving wheel in the transmission mechanism 40, second from
The rotation of moving gear 42 drives the reverse rotation of the first driven gear 41, so that the connecting rod composition 30 on right side breaks away to the right
It is dynamic, realize the unlatching of removable top cover device.
In this alternate embodiment two, it is not necessary to which driving device 20, driving gear 43 and connection driving device 20 and master are set
The chain of moving gear 43, saves power source, alleviates the load of car body, improves the economy of vehicle transport.
It can be seen from the above description that the above embodiments of the present invention achieve the following technical effects：When need
, it is necessary to open two groups of cap assemblies when freighting.First, by driving device drive chain, and then by chain-driving thereon
The driving gear rotation in portion, driving gear drives the rotation of the first driven gear, so that the first chain rotates；First driven gear
Rotation drive with the reverse rotation of the second driven gear of its external toothing along the first driven gear so that the second chain and the
The rotation direction of one chain is on the contrary, drive two connecting rods composition in opposite direction to car body movement outside, final realize fully opens
State, as shown in Figure 9.During head cover fully open state, it is subject to chain and self gravitation effect, can remains and fully open shape
State.
When loading terminates to need to close head cover, driving device negative direction rotates, and makes the first chain and the second chain along phase
Negative direction is moved to body inner side, and then two cap assemblies is driven to be moved to body inner side, is finally reached completely closed state, such as
Shown in Fig. 6.Two cap assemblies are subject to chain and self gravitation effect in completely closed state, can remain and completely close
State.
