Technical field
The present invention relates to hydraulic engineering gate opening/closing technology, particularly a kind of balance gate gear drive opening/closing system.
Background technology
In hydraulic engineering retaining and sluicing process, steel-slag sand ensures that whole engineering is normal, the visual plant of safe operation.In the opening and closing device of steel-slag sand, the hoisting system mostly adopting traditional wire rope stressed according to hydraulic engineering feature and the stressed hydraulic system of piston rod.The feature of above-mentioned opening and closing device is the frictional resistance that hoisting capacity will overcome that steel-slag sand is conducted oneself with dignity and water pressure is brought.
Summary of the invention
For the deficiencies in the prior art, the object of this invention 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, balance gate gear drive opening/closing system provided by the invention, 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 balancing the 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.
Preferably, described backwater gate is the curved metal structure rotated around power transmission shaft.
Further, described counterweight is metal derby or the concrete block of adjustable weight.
Further, be also provided with the spring bearing of annular in the centre bore of described gate pier, described power transmission shaft is connected by the inwall of spring bearing with gate pier centre bore.
Further, described power set are that at least one fluid motor-driven or at least one reducing motor drive.
Further, described gear is internal messing or the external toothing of a gear wheel and at least one pinion.
The invention has the advantages that: novel structure of the present invention, keying scope are large, can realize 360 ° of omnidistance keyings, reduce force of opening and closing, the power set power used obviously diminishes.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention 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 passes through gear train 6 and power set 7 spline joint.
Above-mentioned backwater gate 1 is the curved metal structure rotated around power transmission shaft 2; Counterweight 4 is metal derby or the concrete block of adjustable weight; Also be provided with the spring bearing 5 of annular in the centre bore of gate pier 8, power transmission shaft 2 is connected with the inwall of gate pier 8 centre bore 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 internal messing 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 by the balance arm of force 3 two ends rotated around power transmission shaft 2, the weight of adjustment counterweight 4, the moment that backwater gate 1 is produced is equal with the countertorque that counterweight 4 produces, and power set 7 just overcome the frictional resistance moment that power transmission shaft 2 is formed 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 is H to power transmission shaft 2 center of rotation vertical distance
z, the deadweight of counterweight 4 is W
p, its center of gravity is-H to power transmission shaft 2 center of rotation vertical distance
p, namely form moment in the other direction with metal construction backwater gate 1, have balanced type: G
z× H
z-W
p× H
p=0, the frictional resistance moment that power transmission shaft 2 is formed on gate pier 8 is M
z, it is-N that the power that power set 7 produce forms kinetic moment
z, have balanced type: N
