Abstract
The invention provides a gear transmission starting-stopping system of a balance gate. The gear transmission starting-stopping system comprises a water retaining gate, a power device and a gate pier provided with a central hole and is characterized by being further provided with a balance moment arm, a balance weight, a transmission shaft and a gear train. Two ends of the balance moment arm are respectively connected with the water retaining gate and the balance weight. The transmission shaft is arranged in the central hole of the gate pier, one end of the transmission shaft penetrates the central hole of the gate pier to be connected with the middle of the balance moment arm, and the other end of the transmission shaft is connected with a spline of the power device through the gear train. The gear transmission starting-stopping system is novel in structure, large in starting-stopping range and capable of achieving whole-journey 360-degree starting and stopping and reducing the gate starting-stopping force, and the power of the used power device is reduced obviously.
Description
Technical field
The present invention relates to hydraulic engineering gate opening/closing technology, concrete is a kind of balance gate gear drive opening/closing system.
Background technology
In hydraulic engineering retaining and sluicing process, steel gate is to guarantee that whole engineering is normal, the visual plant of safe operation.In the opening and closing device of steel gate, according to hydraulic engineering feature, mostly adopt traditional stressed hoisting system and stressed hydraulic system of piston rod of wire rope.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 object of this invention is to provide the balance gate gear drive opening/closing system that a kind of hoisting capacity that makes headstock gear greatly reduces.
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 counterweight with backwater gate 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 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 using obviously diminishes.

The specific embodiment
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 counterweight 4 with backwater gate 1 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.
Above-mentioned backwater gate 1 is the curved metal structure around power transmission shaft 2 rotations; 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 around the two ends of power transmission shaft 2 rotations by the balance arm of force 3, the weight of adjustment counterweight 4, the moment of backwater gate 1 generation 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
