Abstract
The present invention relates to a kind of double lifting point worm and gear manual opening-closing machine.Including two worm and gear manual opening-closing machines, connected by jackshaft between described two worm and gear manual opening-closing machines, the worm and gear manual opening-closing machine includes support, worm gear, worm screw and output shaft, transmission case is installed above support, the bearing I that worm gear is socketed by upper and lower ends is in the upper and lower axle bearing in transmission case, worm gear center in the hole is connected in output shaft, worm screw is connected with worm-drive positioned at worm gear side, bearing I I that worm screw is socketed by two ends is in the bearing block of both sides in transmission case, worm screw one end is provided with connected manual pulley, the worm screw other end is located at outside transmission case.The present invention is by adopting Worm Wheel System mode, and is double lifting point again, can realize large-tonnage switching motion, due to being provided with manual pulley in worm screw one end, even if can also carry out switching motion in the case of nothing from far-off regions electricity.
Description
Technical field
The present invention relates to a kind of headstock gear, more particularly to a kind of double lifting point worm and gear manual opening-closing machine.
Background technology
Headstock gear be for all kinds of large-scale plumbing, Hydraulic and Hydro-Power Engineering, for controlling the lifting of all kinds of large and medium-sized cast-iron lock gates and steel gate to reach the purpose of opening and closing.Screw open-close machine is generally divided into rising stem and two kinds of blind rod type, and keying tonnage is little, needs motor to drive and completes switching motion.In this way, under remote mountain areas and the situation without electric power, headstock gear cannot just be operated.
Content of the invention
For drawbacks described above, it is an object of the invention to provide a kind of open and close tonnage greatly, and a kind of double lifting point worm and gear manual opening-closing machine of switching motion can also be carried out under the situation of nothing from far-off regions electricity.
For this technical solution adopted in the present invention it is：Including two worm and gear manual opening-closing machines, connected by jackshaft between described two worm and gear manual opening-closing machines, the worm and gear manual opening-closing machine includes support, worm gear, worm screw and output shaft, transmission case is installed above support, the bearing I that worm gear is socketed by upper and lower ends is in the upper and lower axle bearing in transmission case, worm gear center in the hole is connected in output shaft, worm screw is connected with worm-drive positioned at worm gear side, bearing I I that worm screw is socketed by two ends is in the bearing block of both sides in transmission case, worm screw one end is provided with connected manual pulley, the worm screw other end is located at outside transmission case.
The adapter sleeve that described two worm and gear manual opening-closing machines are socketed by jackshaft two ends is connected with the worm screw of worm and gear manual opening-closing machine.
The bearing I and bearing I I are thrust roller bearing.
It is an advantage of the invention that：The present invention is by adopting Worm Wheel System mode, and is double lifting point again, can realize large-tonnage switching motion, due to being provided with manual pulley in worm screw one end, even if can also carry out switching motion in the case of nothing from far-off regions electricity.
