Please continue to refer to Fig. 5 a, rotating shaft 12 is connected with pull bar 13 by a bindiny mechanism 20, this bindiny mechanism 21 comprises pull bar otic placode 211 and the tie bolt 212 pull bar otic placode 211 and pull bar 13 linked together be welded near rotating shaft 12 end, pull bar otic placode 211 and pull bar 13 realize being articulated and connected by tie bolt 212, make to have certain rotational freedom between this tie bolt 212 and pull bar 13, pull bar otic placode 211.In addition, for anti-unexpected couple so acts on handle operation mechanism, Dump gate is opened, connection otic placode 211 arranges an elastic element 213, in the present embodiment, this elastic element is spring, one end of this elastic element 213 is connected on the connecting bore of connection otic placode 211, and its other end is fixed on under(-)chassis 3 by connecting otic placode 19.By this, by being connected to the pulling force effect of elastic element 213 on pull bar otic placode 211, on the one hand handle operation mechanism being resetted rapidly, controlling the power size pulling handle operation mechanism on the other hand, preventing handle operation mechanism from moving easily.
Refer to the partial enlarged drawing that Fig. 6 a and Fig. 6 b, Fig. 6 a is Tu1Zhong B district, Fig. 6 b is the cross-sectional schematic of C-C in Fig. 2.Pull bar 13 is connected with handle operation mechanism 14.Handle operation mechanism 14 pushes away by being connected with pull bar 13, pull bar 13, makes pull bar 13 drive rotating shaft forward or reversion to rotate, to open or to close Dump gate 2.Handle operation mechanism 14 is arranged on the position away from Dump gate 2, in order to safety of operation, convenience, preferentially, handle operation mechanism 14 is arranged on the middle part bottom tank container.Handle operation mechanism 14 comprises handle 141, handle guide plate 142 and arm pivot post 143, handle 141 and arm pivot post 143 free-running fit be welded on bottom girder 32.Handle guide plate 142 is fixed on the bottom girder 32 of under(-)chassis 3, it has one for limiting the notch 1421 of handle 141 path of motion, this notch 1421 is in thin-and-long, one end of handle 141 is through this notch 1421, and this end has an axle sleeve, this axle sleeve is enclosed within arm pivot post 143, and axle sleeve is free to rotate relative to arm pivot post 143, the other end of handle 141 is control lever, when control lever is pushed into one end of notch 1421, door operating gear is opened, and when control lever is pulled to the other end of notch 1421, door operating gear cuts out.The outer end limit bolt of arm pivot post 143 prevents handle 141 from skidding off arm pivot post 143 simultaneously.Handle 141 extends a connection otic placode to the direction of pull bar 13, and this connection otic placode and pull bar 13 link together by a tie bolt 144.
Above-mentioned door operating gear realizes opening and locking function by following control step:
Open step: first taken out from rotating shaft 12 by limit bolt 17, cancel locking function, then pulling with hand handle 141 makes it move in handle guide plate 142, handle 141 drives pull bar 13 to move, rotating shaft 13 is rotated under the effect of pull bar otic placode 211, second auxiliary section 112(and latch hook) power of being rotated and moving, finally realize latch hook and depart from the first auxiliary section 112(and namely link up with), Dump gate is opened;
Locking step: first Dump gate is put down, now hook and latch hook not automatic attaching catch on, then pull with hand handle 141 and make it move in handle guide plate 142, until hook and latch hook are fitted and caught on, stop drag handle 141.Finally insert in rotating shaft 12 by limit bolt 17, recover locking function, Dump gate is locked.
The power conduction of above-mentioned door opening device starts from handle 141, end at latch hook, the motion of latch hook is controlled by handle 141, thus Dump gate (i.e. back door) the open operation position of vapor tight tank case class transport trolley is changed into the medium position of tank container by traditional position, close back door, operating personal is able to away from discharge position, thus reduce the danger of operation, finally reach the object that back door safe is opened.
The utility model rotating shaft and the point of connection between pull bar and the point of connection between pull bar with handle are undertaken being connected by the form of tie bolt and ensure that each point of connection has great freedom.
The utility model arranges elastic element makes handle reset rapidly on the one hand, controls the power size pulling handle on the other hand, prevents handle from moving easily.
By arranging limit bolt in rotating shaft, the utility model ensures that Dump gate locking state lower rotary shaft does not rotate, thus improve the reliability of this door operating gear.
These are only better possible embodiments of the present utility model, and unrestricted protection domain of the present utility model, all utilization the utility model specification sheetss and the change of the equivalent structure done by accompanying drawing content, be all included in protection domain of the present utility model.
