Abstract
An externally-locked tank cover of bulk cement tanker is characterized in that three pressure plates are uniformly distributed on the external circumference of a tanker port; a lower pressure ring is fixed on the upper hole of the tanker port; an annular groove is formed on the upper annular surface of the lower pressure ring; a seal ring is arranged in the groove; the upper hole of the lower pressure ring corresponds to an upper cover; a nut is fixed at the center of the upper cover; a screw is connected with the screw hole of the nut; a pressure disc having three claws capable of pressing the ends of the pressure plates is screwed on the screw; a handle is hinged with the end of the screw; a lower bearing is fixed on the side edge of the tanker port; an upper bearing is hinged with the lower bearing through a connection rod to form a parallel four-bar linkage mechanism; a rotation shaft is arranged on the upper bearing; and the rotation shaft is fixed on the upper cover through a connection plate. The externally-locked tank cover can rapidly clamp and release the upper cover by the simple and effort-saving operation; and the port seal ring is arranged at the reasonable position so as to ensure high tightness of the tank cover.
Description
Technical field:
The utility model relates to a kind of closing appliance of bulk cement tanker top loading mouth, especially a kind of outer locking-type bulk cement car cover.
Background technology:
Original outer locking-type bulk cement car cover, uniform hinged three pressing plates of tank car mouth circle periphery, tank car mouth lower clamping ring device loam cake suitable for reading, the capping device seal ring, loam cake center screw is connected with screw mandrel, be rotary with three-jaw on the screw mandrel and can push down the platen of pressing plate end, screw mandrel end hinged handle is connected through the hinge between loam cake side and the tank car mouth circle, and it is big to open the cover angle of need turning over, cover breaks away from jar mouth apart from little, operation inconvenience; Seal ring is embedded in the loam cake, in use comes off easily.
Summary of the invention:
The purpose of this utility model provides a kind of outer locking-type bulk cement car cover, the defective of inconvenient operation when the solution cover is opened; Solve the defective that seal ring comes off easily between loam cake and the lower clamping ring.
The purpose of this utility model realizes as follows: uniform hinged three pressing plates of tank car mouth circle periphery, the tank car mouth encloses fixedly lower clamping ring suitable for reading, mouth sealing device loam cake on the lower clamping ring, loam cake center fixation screw, screw internal thread hole is connected with screw mandrel, be rotary with three-jaw on the screw mandrel and can push down the platen of pressing plate end, screw mandrel end hinged handle, tank car mouth circle side is undersetting fixedly, there is a upper bracket to constitute parallel four-bar linkage by connecting rod and undersetting hinge, axis of revolution is set on the upper bracket, and axis of revolution is fixed by connecting plate and loam cake.When opening loam cake, rotating handles drives screw mandrel and rotates, unclamp the thrust of platen to pressing plate, rotate angle of platen, platen and pressing plate are broken away from, upwards open pressing plate, upwards open loam cake, loam cake upwards moves under the effect of parallel four-bar linkage backward, after lower clamping ring exposes fully, makes loam cake center on the axis of revolution rotation and leans against tank car mouth circle side.
The lower clamping ring upper ring surface has cannelure, in this groove seal ring is housed.The seal ring underlying in use is not easy to come off.
The utility model can make loam cake clamp fast, unclamp, and is easy and simple to handle laborsaving; Jar opening sealer circle positional structure is reasonable, guarantees that the cover sealing is tight.
Description of drawings:
Fig. 1 is a front view of the present utility model.
Fig. 2 is a birds-eye view of the present utility model.
The specific embodiment:
With reference to Fig. 1, Fig. 2, the tank car mouth encloses uniform hinged three pressing plates 2 of 13 peripheries, the tank car mouth encloses 13 fixedly lower clamping rings 10 suitable for reading, lower clamping ring 10 upper ring surfaces have cannelure, seal ring 11 is housed in this groove, lower clamping ring 10 is suitable for reading to loam cake 5 should be arranged, loam cake 5 center fixation screws 12, screw 12 internal thread holes are connected with screw mandrel 4, be rotary with three-jaw on the screw mandrel 4 and can push down the platen 3 of pressing plate 2 ends, the negative thread of screw 12 and platen 3 is for revolving in the opposite direction, and the two sections of same screw mandrel 4 are cooresponding anti-silk, screw mandrel 4 end hinged handles 1, the tank car mouth encloses fixedly undersetting 9 of 13 sides, have a upper bracket 6 to constitute parallel four-bar linkage by connecting rod 8 and undersetting 9 hinges, axis of revolution 7 is set on the upper bracket 6, axis of revolution 7 is fixing by connecting plate and loam cake 5.At the opposite side of corresponding upper bracket 6, loam cake 5 is provided with secure latch with tank car mouth circle 13.
