In hydraulic engineering retaining and sluicing process, steel gate is to ensure that whole engineering is normal, the visual plant of safe operation.In the opening and closing device of steel gate, mostly adopt traditional stressed hoisting system and stressed hydraulic system of piston rod of wire rope according to hydraulic engineering feature.The feature of above-mentioned opening and closing device is that hoisting capacity will overcome the frictional resistance that steel gate is conducted oneself with dignity and water pressure is brought.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of balance gate gear drive opening/closing system that the hoisting capacity of headstock gear is greatly reduced.
For achieving the above object, the balance gate gear drive opening/closing system that the utility model provides, comprises backwater gate, power set and is provided with the gate pier of centre bore, it is characterized in that: be also provided with the balance arm of force, counterweight, power transmission shaft and gear train; The two ends of the described balance arm of force are connected with backwater gate and counterweight respectively; Described power transmission shaft is placed in the centre bore of gate pier, and one end of power transmission shaft is connected with the middle part of the balance arm of force through the centre bore of gate pier, and the other end of power transmission shaft is by gear train and power set spline joint.
As preferred version, described backwater gate is the curved metal structure around power transmission shaft rotation.
Further, described counterweight is adjustable weight metal derby or concrete block.
Further, be also provided with annular spring bearing in the centre bore of described gate pier, described power transmission shaft is connected with the inwall of gate pier centre bore by spring bearing.
Further, described power set are that at least one fluid motor-driven or at least one reducing motor drive.
Further, described gear is interior engagement or the external toothing of a gear wheel and at least one pinion.
The utility model has the advantage of: the utility model novel structure, keying scope are large, can realize 360 ° of omnidistance keyings, reduce force of opening and closing, the power set power using obviously diminishes.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Balance gate gear drive opening/closing system as shown in Figure 1, 2, comprises backwater gate 1, power set 7 and is provided with the gate pier 8 of centre bore, it is characterized in that: be also provided with the balance arm of force 3, counterweight 4, power transmission shaft 2 and gear train 6; The two ends of the balance arm of force 3 are connected with backwater gate 1 and counterweight 4 respectively; Power transmission shaft 2 is placed in the centre bore of gate pier 8, and one end of power transmission shaft 2 is connected with the middle part of the balance arm of force 3 through the centre bore of gate pier 8, and the other end of power transmission shaft 2 is by gear train 6 and power set 7 spline joints.
The curved metal structure of above-mentioned backwater gate 1 for rotating around power transmission shaft 2; Metal derby or concrete block that counterweight 4 is adjustable weight; In the centre bore of gate pier 8, be also provided with annular spring bearing 5, power transmission shaft 2 is connected with the inwall of gate pier 8 centre bores by spring bearing 5; Power set 7 are that at least one fluid motor-driven or at least one reducing motor drive; Gear train 6 is interior engagement or the external toothing of a gear wheel and at least one pinion.
Operating principle is as follows: curved metal structure backwater gate 1 and counterweight 4 are fixed on the two ends that rotate around power transmission shaft 2 by the balance arm of force 3, the weight of adjustment counterweight 4, the moment that backwater gate 1 produces is equated with the countertorque that counterweight 4 produces, and power set 7 just overcome the frictional resistance moment that power transmission shaft 2 forms on gate pier 8.
The course of work is as follows: the deadweight of curved metal structure backwater gate 1 is G
z, its center of gravity to power transmission shaft 2 center of rotation vertical distances are H
z, the deadweight of counterweight 4 is W
p, its center of gravity to power transmission shaft 2 center of rotation vertical distances are-H
p, form moment in the other direction with metal construction backwater gate 1, there is balanced type: G
