When actuator 3 is arranged in the middle of car body, only can reserve the installing space of actuator 3 in the centre of car body, then before and after car body, the space of both sides all can be used for the carrying of goods, improves the capacity utilization of car body largely; On the other hand, actuator 3 is arranged on centre, propulsive effort comparatively balancedly can be delivered to each door 21 of both sides, front and back, improves the synchronism of door 21 action, realizes the synchronous opening/closing of a mouth 11, to improve the control accuracy of rate of discharging and outturn.

Attaching parts 22 can also be set in the centre of car body, in the both sides of attaching parts 22, spacing hole is set, spacing hole extends in the vertical, and spacing hole's length is in the vertical arranged according to propping up the distance vertically moved when mouth 11 is propped up in door 21 keying, the distance vertically moved when usually can equal or prop up mouth 11 slightly larger than door 21 keying; The Men Tijun being in both sides is provided with locating part within it, and described locating part can be limit pull rod etc., and position-limited lever is movably connected in the spacing hole corresponding with it, and vertically moves in the scope that spacing hole limits.That is, before and after actuator 3 drives while the inside and outside movement in the vertical of the door body of both sides, to the position-limited lever that door body connects also corresponding movement in spacing hole.

Usually, position-limited lever and door body can adopt to weld etc. and be fixedly connected with mode; Described flexible connection can be the sliding block joint modes such as pinned connection, also can be the rolling connection modes such as roller; Described spacing hole can be set to length direction slotted hole structure in the vertical.

The door body of both sides, front and back connects as one by arranging of above-mentioned attaching parts 22, plays certain position-limiting action to the relative motion of two bodies, prevents each door 21 from vertically moving apart from excessive and affect the keying of adjacent mouth 11, improves motion credibility; Meanwhile, attaching parts 22 makes both be in same plane after being connected by the door body of both sides, front and back, two bodies are avoided to produce crooked, ensure the driving reliability of actuator 3, there will not be a body crooked and stuck or cause comparatively galling, improve the stability of motion.

Please further refer to Fig. 6, Fig. 6 be car body provided by the present invention complete gear door open and close process schematic.

In detail, actuator 3 can comprise front rod 31, rear linking rod 32 and cylinder 33, and front rod 31 and rear linking rod 32 are hinged, and front rod 31 is hinged with the door body being in front side, rear linking rod 32 is hinged with the door body being in rear side, and cylinder 33 is hinged between front rod 31 and rear linking rod 32; Cylinder 33 stretches in the vertical, when the piston rod of cylinder 33 is protruding, cylinder 33 outwards promote front rod 31 and rear linking rod 32 mutually away from, to be in the door body outwards movement of both sides, front and back, as shown in dotted portion in Fig. 6, then prop up the below that door 21 is pushed to a mouth 11, a mouth 11 is in closure state, as shown in Figure 5; Or the piston rod of cylinder is inwardly retracted to cylinder barrel, with pull front rod 31 and rear linking rod 32 close to each other, so that the door body being in both sides, front and back moves inward, as shown in bold portion in Fig. 6, then prop up door 21 and be pulled to region between two mouths 11, mouth 11 will be propped up open, as shown in Figure 4.

Be appreciated that cylinder 33 can also adopt other propulsions source to substitute, such as, telescopic oil cylinder or motor etc. can be adopted to drive front rod 31 and rear linking rod 32 is close to each other or away from, to realize the driving to door 21.

In the above-described embodiment, front rod 31 and rear linking rod 32 is adopted to realize the connection with front/rear door body, and then realize vertically moving of front/rear door body by the mode of cylinder 33 drive link longitudinal sliding motion, due between front rod 31 and rear linking rod 32, between two connecting rods and cylinder 33, be between two connecting rods and door body hinged, then above-mentioned connection mode requires lower to the right alignment between the piston rod of cylinder 33 and door body, there will not be the stuck phenomenon between two bodies of cylinder 33, and then ensure that the reliability of driving.

Those skilled in the art are to be understood that, due between front rod 31 and rear linking rod 32, between two connecting rods and cylinder 33, be between two connecting rods and door body hinged, and only need a body to vertically move in a process of mouth 11 keying, therefore, the inhibiting device such as the longitudinal sliding motion track of a body can be set, opposite house body vertical and laterally to limit, prevents it from moving up and down or double swerve, to ensure a stability of body motion.

Be appreciated that, vertical and the horizontal restriction of door body described herein not refers to that whole door body is vertical and transversely do not have degree of freedom completely, door body is completely fixed, just say door body vertical and transversely only can limit space in move, its degree of freedom is less, substantially there is not horizontal and vertical displacement, namely sense of motion exists only in longitudinal direction, not the connection modes such as the vertical of door body and horizontal employing welding is fixed.Such as, the thickness direction of door body is present in vertical, therefore needs the installation that enough spaces complete a body on vertical, and has necessarily little gap, its generation can be allowed to vertically move, but not it be fixed completely; The width of door body is in transverse direction, certainly also needs enough installing spaces to realize holding door body structure in the horizontal, is unlikely to that it is laterally completely stuck simultaneously and hinders it to vertically move.Visible, transverse direction described herein and vertical spacing be comparatively speaking, its objective is the stability in order to ensure body movement in the vertical.

For realizing the installation of actuator 3, leg-of-mutton installing space can be formed in the middle of car body, the slide bar 34 of longitudinal extension is set between the limit being then in both sides, front and back in triangle space, slide bar 34 is arranged the slide block 35 with its sliding block joint, slide block 35 is connected with the barrel of cylinder 33, as shown in Figure 4; The piston rod of cylinder 33 is hinged with the door body of wherein side, the barrel end of cylinder 33 and the door body of opposite side hinged, then slide block 35 and slide bar 34 are equivalent to guide, when the piston rod of cylinder 33 stretches, cylinder 33 is subject to the spacing of slide block 35 and stretches in the vertical, thus drive the door body of its both sides longitudinally in move or move outward.

That is, actuator 3 can be set to three linkage rod slide block mechanisms be made up of slide block 35 and front rod 31, rear linking rod 32, cylinder 33, and when actuator 3 adopts above-mentioned three linkage rod slide block mechanism, its structure is simple, the stability of moving can be ensured, and be easy to safeguard.
