Detailed description of the invention
Further set forth design feature of the present utility model below in conjunction with accompanying drawing and specific embodiment.
Pneumatic the putting down of a kind of single cylinder as depicted in figs. 1 and 2 opened automatic material discharging door, and two fan door leafs 1 and the Pneumatic assembly 2 that controlled by PLC and provide are provided; The outside of described door leaf 1 be welded with respectively with discharging platform on door-hinge pit built-in fitting and lower door-hinge pit the built-in fitting upper door-hinge pit assembly 3 and the lower door-hinge pit assembly 4 that match; Described upper door-hinge pit assembly 3 and lower door-hinge pit assembly 4 are in concentric axis; The door-hinge upper end of the upper door-hinge pit assembly 3 of a door leaf 1 is provided with the long arm swing vertical with door-hinge axis 5 therein, and the angle between long arm swing 5 and door leaf 1 is 45 degree, and long arm swing 5 is centrosymmetric with door-hinge; One end of described long arm swing 5 is flexibly connected with the push rod of Pneumatic assembly 2, and the short swing arm 6 arranging on the door-hinge of the other end of long arm swing 5 by a long connecting rod 7 and the upper door-hinge pit assembly 3 of another door leaf 1 is connected, and the angle between short swing arm 6 and door leaf 1 is 45 degree.
In order to make direction that door leaf 1 opens toward the same side, one end that described long arm swing 5 is flexibly connected with the push rod of Pneumatic assembly 2 and short swing arm 6 are in the same side of door leaf 1.
For the amplitude that door leaf 1 is opened is consistent, described short swing arm 6 is 1/2 of long arm swing 5.
The centre side of the being provided with mortise of described long arm swing 5, the square tenon arranging with door-hinge end mates and is socketed; Described short swing arm 6 one end side of being provided with mortises, and the square tenon arranging with the door-hinge end of door-hinge pit assembly 3 on place door leaf 1 mates and is socketed.
Between two described door leafs 1, be provided with weather strip between door leaf 1 and body of wall, make two door leafs 1 can with body of wall close contact, under the thrust of Pneumatic assembly 2, weather strip is compressed, thereby reaches the requirement of sealing.
This equipment is under the promotion of the power that produces at the operating pressure oil of hydraulic jack of the push rod (piston rod) that utilizes Pneumatic assembly 2, promote or retract the long arm swing 5 being connected on piston rod, and the square mortise of the centre of long arm swing 5 is just enclosed within on rotating shaft side's tenon of a door, like this, upper door-hinge pit assembly 3 and lower door-hinge pit assembly 4 are all welded on a door leaf 1 with one heart, will be driven and do equidirectional rotation when switch door leaf 1.And long arm swing 5 is connecting a long connecting rod 7, the other end of this long connecting rod 7 is connecting again one end of the short swing arm 6 of another door leaf 1, the other end of short swing arm 6 is just contained in by square mortise on the square tenon of door-hinge of the upper door-hinge pit assembly 3 of another Yishanmen, so when the piston rod of Pneumatic assembly 2 is in the time releasing or retract, because the two ends of long arm swing 5 are to do respectively reciprocal rotation in the time rotating, so, Zhe Tao mechanism can complete the design action requirement of switch gate simultaneously, making counter-rotation because just inevitable when the short swing arm 6 of another door leaf 1 that long connecting rod 7 is connecting is moved, so release of the and then piston rod of Pneumatic assembly 2 that two fan doors just can be synchronous and retract simultaneously and also synchronously to complete the action request that it opens the door and closes the door.
The automatic program control system being formed by PLC, and each Dump gate independent control cabinet of having a PLC to branch away, and in control room, there is total control system, can on total display screen, see and operate the action of controlling all dischargings, so can control in time a Dump gate or several Dump gate Simultaneous Switching door or switch gate in order, can also utilize the pressure of controlling hydraulic oil pump to control the speed function of releasing and retracting, adjust with this desired door speed of opening of design that reaches.Compare with double hydraulic cylinder, can save a set of hydraulic cylinder to reduce costs, also improved the net synchronization capability of twin-tub switch gate simultaneously.
