Further, include a upper limit travel switch and limitation travel switch once, follow gate when block and rise to the upper limit travel switch and contact, this upper limit travel switch accessory drive shuts down, and this moment, gate opening was to maximum; Follow gate when block and drop to the lower limit travel switch and contact, this lower limit travel switch accessory drive shuts down, this moment closing gate.

Further, described drive unit adopts stepper motor, is connected with a shaft coupling between this stepper motor output shaft and screw tip, is provided with the motor mount of this stepper motor of supporting on described base plate.

Further, also include and be arranged at the screw rod periphery and be fixed in bearing and bearing support on motor mount.

Further, also include the gathering sill that is fixed on described base plate and is positioned at described gate both sides, described gate under the drive of screw rod along the gathering sill lifting.

Further, described screw rod also is connected with stop nut.

By above-mentioned to description of the present utility model as can be known, compared with prior art, the utlity model has following beneficial effect:

1, the gate-lowering mechanism structure in the utility model step, realize the unlatching (closing) of automatic controlling gate by the cooperation of drive unit, screw rod and lifter plate etc., and is simple in structure.

2, drive unit adopts cloth to advance motor, according to the rotating cycle drive screw that arranges just (instead) to rotation, on lifter plate (under) move and drives the extremely height of setting of whole gate opening (closing), gate opening is smooth, precision is high.

3, the utility model is provided with range controlling mechanism, for computer provides the signal that puts in place, thus the duty of accessory drive, automaticity is high.

The specific embodiment

Below the utility model will be further described by the specific embodiment.

With reference to Fig. 3, Fig. 4 and Fig. 5, a kind of gate-lowering mechanism structure is used for relative base plate 2 liftings of regulating gate 1, comprises screw rod 3, drive unit 4 and lifter plate 5.This screw rod 3 is arranged in lifter plate 5 and coordinates with lifter plate 5 inner threads, and this lifter plate 5 is fixed on gate 1 by a jam plate 51.Open the hole on jam plate 51, lifter plate 5 upper end perforates, screwed hole is opened in the lower end, can carry out auto-compensation for screw rod 3 rotations, guarantees that gate 1 switch is smooth.Drive unit 4 is fixed on base plate 2 and connects drive screw 3 and rotates 1 lifting of drive gate.

Fig. 5, Fig. 6 also include the range controlling mechanism of regulating gate 1 stroke, and the trip controlling organization comprises that one is fixed in link stopper 6 on gate 1, a upper limit travel switch 7A and limitation travel switch 7B once.Travel switch inside is provided with constant open contact, for computer provides the signal that puts in place.Following gate 1 when link stopper 6 rises to upper limit travel switch 7A and contacts, elastomeric element on upper limit travel switch 7A is depressed (constant open contact is closed), this upper limit travel switch 7A sends a signal to computer and comes accessory drive 4 to shut down, and this moment, gate 1 was opened into maximum; Following gate 1 when link stopper 6 drops to lower limit travel switch 7B and contacts, elastomeric element on lower limit travel switch 7B be depressed (constant open contact closed), this lower limit travel switch 7B sends a signal to computer and comes accessory drive 4 to shut down, and this moment, gate 1 was closed.

Further, drive unit 4 adopts stepper motors, is connected with a shaft coupling 8 between this stepper motor output shaft and screw rod 3 tops, is provided with the motor mount 41 that supports this stepper motor on base plate 2.Can customize height gate 1 and open height, only need to come regulating gate 1 to open to desired height by computer control step motor rotating cycle.
