Double-driving variable speed gate hoist

Abstract

The invention provides a double-driving variable speed gate hoist; the hoist comprises a high-speed motor, a low-speed motor, a bearing nut, a threaded rod, a planetary gear speed reduction component, a multi-stage speed reduction gear unit and a few teeth difference speed reduction gear unit; the planetary gear speed reduction component, the multi-stage speed reduction gear unit and the few teeth difference speed reduction gear unit are arranged in a transmission case; the few teeth difference speed reduction gear unit is composed of a first flow dividing gear, an idle wheel meshed with the first flow dividing gear, a second flow dividing gear meshed with the idle wheel, and a cam mechanism arranged outside the bearing nut; the cam mechanism is connected with a transmission shaft of each of the first flow dividing gear and the second flow dividing gear by a cam transmission shaft; the first flow dividing gear is meshed with a tail end gear of the planetary gear speed reduction component; the high-speed motor is connected with the input end of a planetary carrier of the planetary gear speed reduction component; the low-speed gear is connected with the input end of the planetary gear speed reduction component by the multi-stage speed reduction gear unit. According to the double-driving variable speed gate hoist disclosed by the invention, the problem that the current worm wheel and worm hoisting mechanism cannot hoist a pressure gate under a large capacity is solved, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to gate hoisting technology for water conservancy projects, in particular to a double-drive variable-speed gate hoist that can replace a screw hoist and a hydraulic hoist. Background technique [0002] In the conventional opening and closing technology of metal structure gates in water conservancy projects, there are mechanisms that are hoisted by wire ropes, such as portal hoists, bridge hoists, trolleys, fixed hoists and electric hoists, etc., and there are also mechanisms that are driven by worm gears. Screw hoist, as well as a hydraulic hoist that controls the movement of cylinders and piston rods through a hydraulic pump station. [0003] The wire rope winch hoist is a motor connected to the reel through a brake and a reducer. One end of the wire rope is connected to the reel, and the other end is connected to the fixed pulley block and its movable pulley block, and the movable pulley block is connected to the gate. The stro...

Problems solved by technology

[0004] The purpose of the present invention is to provide a new double-drive variable-speed gate hoist that can replace screw hoist and hydraulic hoist. The less difference reducer and the planetary gear reducer mesh transmission, which can not only solve the problem that the existing worm gear and worm opening and closing mechanism cannot open and close the large-capacity downpressure gate, but also reduce maintenance costs
