Abstract
The utility model relates to a pin tooth type opening-closing machine for hydraulic engineering, comprising a power transmission system which is composed of a power source, a reduction box, a drive gear and a main shaft (7). A gate (11) is fixedly connected with a gantry (10), and upright posts arranged at both sides of the gantry (10) are provided with pin teeth. Both ends of the main shaft (7) are provided with gears (8) which are engaged with the pin teeth (19) arranged on the gantry (10), and the place where the back of the gantry corresponding to the action point of pin tooth drive is provided with an energy dissipating wheel (18). As the utility model adopts a pin tooth drive structure, the utility model has large drive torque, accurate stroke position and long service life, because a cylindrical pin is detachable, the utility model has convenient maintenance.
Description
The utility model relates to a kind of water engineering machinery, specifically a kind of headstock gear.
Headstock gear is a kind of of many uses and important plant equipment in the hydraulic engineering, as pumping plant, reservoir, hurdle, river course dam etc. in order to regulating pondage.Headstock gear at present commonly used has screw mandrel formula and steel wire rope type, and in use, screw mandrel formula headstock gear be because the little flexible and not anti-use of rigidity and because of single-point opens and closes gate can cause the gate swing, and it is inaccurate to open and close the stroke location; The steel wire rope type headstock gear is that the gravity fall by gate self is come closed shutter, and it is unreliable to open and close, is subject to buoyancy effect and is difficult for locating when causing gate to fall.Moreover wire rope and gate seat connected mode be science very not also, and obscission can take place, and easily causes the accident.
The purpose of this utility model provides the accurate positioning of a kind of keying stroke, headstock gear safe in utilization, reliable with regard to being to overcome the deficiency of above-mentioned prior art existence.
The purpose of this utility model can realize by following measure:
The utility model comprises power drive system, the gate of being made up of power source, reduction box, travelling gear and main shaft, and gate is fixed on the portal frame; Be provided with the pin tooth on the column of portal frame both sides; The gear that is meshed with pin tooth on the portal frame is being installed on the main shaft; Be provided with the power apparatus that disappears at the portal frame back side.
Portal frame is made by channel-section steel, also can adopt other material to make; The pin tooth is to be welded on the steel plate that is parallel to each other on the portal frame and the straight pin that is equally spaced that installs thereon constitutes, and straight pin is dismountable; The power apparatus that disappears is the wheels that disappears that is installed in portal frame back side correspondence and pin tooth gearing point place, its width is less than the width of portal frame channel-section steel groove, its effect is that the wheels face that disappears can fully be contacted with portal frame, to eliminate the horizontal component that acts on the portal frame in pin tooth transmission process.
Because the utility model has adopted pin tooth drive mechanism, so driving torque is big, the stroke accurate positioning, long service life, and because straight pin is dismountable, easy to maintenance.
Drawing of the present utility model is described as follows:
Fig. 1 is the front view of the utility model pin tooth driving opening closing gate.
Fig. 2 is the utility model power drive system figure.
Fig. 3 is a portal frame pin rack top plan view.
The utility model is described in further detail below in conjunction with specific embodiment (accompanying drawing):
The utility model provides power by motor 1, man-operated mechanism 14,13, handle 12 and gear clutch 15 as shown in the figure, and reduction box 4, travelling gear 5,6 and main shaft 7 are formed power drive system, and gate 11 is fixed on the portal frame of being made by channel-section steel 10; Be provided with pin tooth 19 on the column of portal frame 10 both sides, pin tooth 19 constitutes for the straight pin that is equally spaced that is welded on the steel plate that is parallel to each other on the portal frame 10 and install thereon, straight pin removably connects with the form and the steel plate of Luo bolt, be beneficial to maintenance, replacing to straight pin: main shaft 7 two ends all are equipped with the gear 8 that is meshed with pin tooth 19 on the portal frame 10 by bearing support 9 supportings that are fixed on the ground foundation at the two ends of main shaft 7; Correspondence is provided with the wheels 18 that disappears with pin tooth gearing point place at the back side of portal frame 10, width is less than the width of portal frame channel-section steel groove, its effect is that the wheels face that disappears can fully be contacted with portal frame 10, to eliminate the horizontal component that in pin tooth transmission process, acts on the portal frame 10, prevent that portal frame 10 from tilting, the wheels 18 that disappears is by axle 17, bearing support 16 supportings; Limit by row and following limit by row place all are equiped with limit switch on portal frame, with the keying limit of restriction portal frame.
The operating principle of the present utility model and the course of work are as follows:
Power source is provided by motor 1, when needs open and close gate, connect power supply, electromagnetic brake 2 is opened automatically, manually open gear clutch 15, man-operated mechanism 14 and motor 1 are broken away from, press start button then, motor 1 rotation passes to the pin tooth 19 that is arranged on 10 liang of heel posts of portal frame with power by reducer 4, gear 5,6,8 and main shaft 7, force portal frame 10 to drive gate 11 and vertically move, after gate opening/closing is finished, deenergization 1, electromagnetic brake 2 lockings make gate be parked in preposition.
When having a power failure, power source can be by manually providing, deenergization at first, manually open electromagnetic brake, by gear clutch 15 man-operated mechanism 14,13 is linked to each other with motor shaft, manpower provides power by shaking handle 12, the power transmission process is identical with the motor power transmission process, after gate opening/closing is finished, manually, make gate be parked in preposition with electromagnetic brake 2 lockings.
