Summary of the invention

The technical issues that need to address of the present invention, be in the prior art, if single rely on electrical control to carry out the feed ditch gate when controlling automatically, can be because certain electric part performance be malfunctioning, and cause control appliance to lose efficacy finally causing gate out of hand and serious consequence takes place, need to increase by one safeguard procedures for this reason.The object of the present invention is to provide a kind of mechanical clutch protector of automatic control gate; under the situation that electic protection lost efficacy; play a role by it; stop gate that commander's action takes place not listen; the objective of the invention is to take following technical scheme to realize; a kind of mechanical clutch protector of automatic control gate; comprise a motor that is used to drive the vertical axis screw mandrel of gate lifting moving; horizontal axis of rotation of this driven by motor; it is characterized in that; one side end of horizontal axis of rotation is provided with a wheel disc; wheel disc drives a driven separation wheel, and this driven separation wheel drives the same central shaft rotation of coaxial driving wheel, and this axostylus axostyle passes through worm gear; worm component mechanism is connecting the gate axis screw mandrel cover that vertically is provided with; at worm gear; worm component mechanism top also is provided with the mechanism of cutting off that protects the bolt composition.In the middle of axial filament bar cover when rotating along axle, but the gate that axis screw mandrel below is connected then oscilaltion play the effect that opens and closes current.

Described driven separation wheel is fixed a sprocket wheel I with the other end of the coaxial axostylus axostyle of driving wheel, and a sprocket wheel II who places the lower end in its interlock, and this sprocket wheel II is connected with one and is equipped with the active handwheel that has a power failure and described horizontal rotary shaft continuation is rotated.

Described by cutting off in the mechanism that driving axle housing, passive axle sleeve, three protection bolts are formed; this protection bolt is made by the soft metal of easy fracture; three bolts are 120 ° of angles and are separately fixed on this mechanism's holder, move up and down thereby make upper and lower axle sleeve compress drive axis screw mandrel.

The invention has the beneficial effects as follows; this mechanical clutch protector can be controlled the effect of playing in the safety protecting method with the electrical control cabinet complementation automatically at gate; when electrical control division lost efficacy for some reason, this device can replace up, prevented that gate action was lost efficacy and the injury that brings.
