The utility model content
The utility model aim to provide a kind of simple and reasonable, rapid operation, flexibly control sluice gate aperture, improve the sluice gate elevating mechanism of metering accuracy, to overcome the deficiencies in the prior art.
A kind of sluice gate elevating mechanism by this purpose design, comprise door frame, main shaft, gear and tooth bar door, tooth bar engaged transmission on the wheel and rack door, its architectural feature are that main shaft one end is provided with click transmission and rocking arm thereof, by the lifting of rocking arm driving rack door.
Described rocking arm one end is provided with an open slot, and the transmission of ratchet and ratchet is installed in the open slot; Ratchet is installed in an end of main shaft by key, and ratchet is fixed on the rocking arm by bearing pin.
Described ratchet is the two-way shape ratchet that colludes.Ratchet is circular arc dihedral or water caltrop shape, and inward at both ends is provided with colludes the shape ratchet.Rocking arm open slot bottom is provided with an endoporus, is provided with spring and steel ball in the endoporus, and ratchet stage casing and steel ball be against contacting, and commutates up and down by extrusion spring.
Compared to existing technology, the utility model is simple and reasonable, processes easily and assembles, and manufacturing cost is lower, rapid operation, and the aperture of sluice gate can be controlled flexibly, and has improved metering accuracy.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Referring to Fig. 1-Fig. 2, this sluice gate elevating mechanism comprises door frame 6, main shaft 5, gear 4 and tooth bar door 7, tooth bar 7.1 engaged transmission on gear 4 and the tooth bar door 7, and rocking arm 8 bottoms are provided with an open slot 8.1, and the transmission of ratchet 13 and ratchet 11 is installed in the open slot 8.1.Ratchet 13 is installed in an axle end of 5 by key 3, and ratchet 11 is installed in the open slot 8.1 by bearing pin 12.Door frame 6 is fixed on the body, and door frame 6 both sides are provided with U-shaped or L shaped groove, and tooth bar door 7 is plugged in the groove of door frame 6, but above-below direction moves.Bearing 2 and bearing support 1 are equipped with in the two ends of main shaft 5, and bearing support 1 is anchored on the door frame 6.Rocking arm 8 is limited on the axle 5 by spring washer 15, nut cap 14 and positioning sleeve 16, alignment pin 17.
Referring to Fig. 3, open slot 8.1 bottoms of rocking arm 8 are provided with an endoporus 8.2, and endoporus 8.2 is provided with spring 9 and steel ball 10.Spring 9 is pressed in the endoporus 8.2 by steel ball 10 under the effect of ratchet 11.Ratchet 11 is the two-way shape ratchet that colludes.The last ratchet of ratchet 11 inserts in the gear teeth of ratchet 13, and the involute extrados of ratchet 11 is contacted at the basic circle place of ratchet 13 with the involute cambered surface of ratchet 13, and the active force of 13 pairs of ratchets 11 of ratchet just passes through the center of rotation of ratchet 11.Because the active force of 13 pairs of ratchets 11 of ratchet by the center of rotation of ratchet 11, is minimum so rotate the power of rocking arm 8, reaches the labour-saving purpose.The last ratchet of ratchet 11 and ratchet 13 gear teeth meshing, rocking arm 8 clockwise rotates, and drives ratchet 11 and gear 4 clockwise directions and rotates, and tooth bar door 7 moves downward under the drive of tooth bar 7.1.After turning over certain angle,, need to switch the ratchet 11 and ratchet 13 positions of engagement this moment if tooth bar door 7 does not reach desired falling head.During switching, counter-rotation rocking arm 8, ratchet 11 can be deviate from from the engaging groove of ratchet 13, but because steel ball 10 is under the active force of spring 9, can make ratchet 11 near ratchet 13 all the time, therefore in rocking arm 8 counter-rotation processes, ratchet 11 can enter in the next teeth groove of ratchet 13 automatically.Continue to clockwise rotate rocking arm 8, until meeting the requirements of falling head.
Referring to Fig. 4, when during the following ratchet of ratchet 11 and ratchet 13 gear teeth meshing, rotating counterclockwise rocking arm 8, can drive tooth bar door 7 by rotating mechanism and engaging mechanism and rise by external force, in like manner also can regulate the engaging tooth position of ratchet 13 and ratchet 11, meet the requirements of lifting height.
Referring to Fig. 5, gear 4 is installed on the axle 5 by key 3, and the tooth bar 7.1 on the gear teeth on the gear 4 and the tooth bar door 7 meshes, and accurately controls the heave amplitude of tooth bar door 7.
Among Fig. 3, " II " is the meshing point of ratchet and ratchet, the application point of power just, and ratchet is to the active force " F1 " of the ratchet center of rotation by ratchet; " F2 " is the force direction of steel ball to ratchet.The rotation direction of arrow is respectively rocking arm rotation direction and ratchet rotation direction.
