Abstract
The utility model is a gear-rack type headstock gear for gate, which is characterized in that: the panel of the arc shaped gate in hydropower station is provided with the large gear ring of an open gear or the panel of the plane gate is provided with a rack, the large gear ring or the rack are fixed on the arc shaped gate or the plane gate, the front end of the panel is provided with a deceleration motor and a pinion coordinated with the deceleration motor, the pinion is meshed with the large gear ring. The gear-rack type headstock gear of the utility model does not need to design a special headstock gear room, the working is reliable, the applicability is strong, when applied to water conservancy and hydropower engineering, the amount of civil engineering works can be greatly reduced.
Description
Technical field
The present invention relates to water conservancy, power station engineering infrastructure technical field, specifically be used for the pinion and-rack headstock gear of gate.
Background technology
The hydroelectric development of China is just entering the developing stage of a high speed, a large amount of large, medium and small type power stations go into operation just successively, the gate hoist number of devices of required use is numerous, and traditional gate hoist equipment kind is very limited, and all types of headstock gears also have corresponding shortcoming.
The opening and closing device that is used for the power station gate at present mainly contains following several types: hydraulic hoist, gantry gate hoists, fixation winding type hoist, mobile winch hoist (chassis) and electric block.These several gate opening/closing equipment all need bigger arrangement space and basis in actual applications.With arc door opening and closing device is example, what use was more at present is hydraulic hoist, hydraulic hoist is made up of equipment such as hydraulic jack, pumping plant, pipelines, and down-the-hole type Segment gate hydraulic hoist need be opened a very big hoist chamber and a corresponding transport channel of size usually and be used to arrange the hydraulic pressure opening and closing device.For down-the-hole arc door, the excavation of large-sized hoist chamber and relevant access gallery will be extremely uneconomic.In addition, because the needs that hydraulic hoist is arranged, its hoisting capacity is arc door radius vertically, has reduced the keying moment of gate, causes the bigger hoisting capacity of gate needs for same size thus.Fixation winding type hoist also has similar use shortcoming.
Summary of the invention
The purpose of this utility model provides a kind of gate opening/closing very for convenient and swift, can save the pinion and-rack headstock gear of headstock gear arrangement space.
The utility model is at the shortcoming of existing gate opening/closing equipment, by the research to the gate opening/closing process, for the keying of gate provides a kind of brand-new solution.The pinion and-rack headstock gear utilizes the principle of gears engaged, directly provides reliable moment for the keying of gate by a pair of exposed gear.
The technical solution of the utility model is: (keying with Segment gate is an example) installs tooth bar on the bull gear of installing exposed gear on the panel of Segment gate or the panel at plane gate, bull gear or tooth bar are fixedly on the Segment gate or on the plane gate, arrange reducing motor and cooperate pinion with it in the place ahead of panel
Pinion and bull gear engagement drive gear wheel and rotate, and make gate obtain to open and close required moment; Pinion drives by reducing motor.
The pinion and-rack headstock gear of power station Segment gate is two suspension centre settings, synchronous for guaranteeing two Hanging Point Gate headstock gear two points, improve the stressing conditions in the gate opening/closing process, realize being rigidly connected (again two drive motors being aided with electric sychronisation) by the mechanical synchronization axle between two suspension centres of headstock gear.
Pinion and-rack headstock gear of the present utility model does not need to be the special hoist chamber of its layout design, reliable operation, and applicability is strong, is applied to can reduce civilwork engineering quantity greatly in the Hydraulic and Hydro-Power Engineering.
Description of drawings
Fig. 1 is a pinion and-rack headstock gear structural representation of the present utility model.
Fig. 2 is the A-A sectional drawing among Fig. 1.
Among the figure, the 1-Segment gate, the 2-bull gear, the 3-pinion, 4-mechanical synchronization shaft stool, the 5-synchronizing shaft, 6-(three-in-one) slows down into motor, the 7-panel.
The specific embodiment
The layout of waterpower formula ship lift ship railway carriage or compartment, water of hydration power station door headstock gear describes in detail the utility model.
As shown in Figure 1, about the panel 7 of arc ship railway carriage or compartment door, arrange an opposite opened bull gear 2, the open type bull gear is fixed on (or installing tooth bar on the panel of plane gate) on the Segment gate panel, reducing motor 6 and pinion 3 are arranged in the place ahead of panel, pinion and bull gear engagement, drive bull gear and make gate obtain to open and close required moment, by the reducing motor driving pinion, reducing motor and pinion are arranged in the hoist chamber of end, ship railway carriage or compartment.Because the keying speed of gate is much smaller with respect to the rotating speed of motor, for obtaining the keying speed that gate needs, also needing lower rotating speed of reducing motor output except exposed gear speed reducing ratio reasonable in design, is the drive motors of pinion and-rack headstock gear so select the planetary reduction gear motor.For improving the stressing conditions in the gate opening/closing process, eliminate because 2 the asynchronous gate that causes is subjected to unnecessary external force, two suspension centres of pinion and-rack headstock gear should be able to be realized driven in synchronism, directly couple together with mechanical synchronization shaft device 4,5 reducing motors two suspension centres, the rigidity that realizes driving force synchronously (can be when being provided with the mechanical synchronization system, electric synchro system is set, auxiliary and supplementary function) to the synchronization onwards of two suspension centres.The power that the rack-and-pinion headstock gear is provided is vertical with arc door radius, therefore can effectively reduce the headstock gear capacity, has also saved the headstock gear arrangement space simultaneously greatly.
Claims (2)
1. pinion and-rack headstock gear that is used for gate, it is characterized in that on the bull gear of installing exposed gear on the panel of power station Segment gate or panel, installing tooth bar at plane gate, bull gear or tooth bar are fixedly on Segment gate or the plane gate, arrange reducing motor and the pinion that cooperates with it in the place ahead of panel, pinion and bull gear engagement.
2. the pinion and-rack headstock gear that is used for gate according to claim 1 is characterized in that being rigidly connected by the mechanical synchronization axle between two suspension centres of headstock gear.
