Screw type open-close system for radial gate

Abstract

The invention discloses a screw type open-close system for a radial gate. The screw type open-close system comprises the radial gate arranged at the low place of a river dike and a gate hoist arranged at the high place of the river dike, wherein the gate hoist comprises fixed mounting bases, a movable mounting base, a motor, a transmission, a nut and a screw, the fixed mounting bases are fixedly arranged on the river dike, the movable mounting base is movably arranged on the fixed mounting bases and rotates in the current direction under the river dike, the motor, the transmission and the nut are arranged on the movable mounting bases, a rotating shaft of the motor is connected to the nut through the transmission and drives the nut to rotate, screw threads are arranged on the hole wall of a central through hole of the nut, the central through hole of the nut sleeves the upper section of the screw, the lower end of the screw is connected to a lifting lug of the radial gate, and the screw can rotate relative to the lifting lug. The screw type open-close system for the radial gate adopts the screw to drive the radial gate to rotate to open and close, the boundary dimension of the gate hoist is shortened, the structure is compact, the confined space of a room of the gate hoist is saved and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to a gate opening and closing system, in particular to a screw type arc gate opening and closing system. Background technique [0002] The curved gate is a gate whose water-retaining surface is a partial arc of a cylinder. The supporting hinge seat of its support arm is located at the center of the circle, and the gate rotates around the supporting hinge seat when opening and closing. Because the arc gate does not have a door slot, the opening and closing force is small, and the hydraulic conditions are good, it is widely used in various types of waterways as a working gate. The arc gate hoisting system is composed of arc gate and hoist. The arc gate is generally installed at the lower part of the river dam, and the hoist is installed at the high place of the river dam. The hoist is used to open and close the arc gate. . [0003] In the existing arc gate hoisting system, the hoist mostly adopts the hoist type arc gate hoist, and...

Problems solved by technology

However, due to the large transmission ratio of the driving device of the hoist type arc door hoist, the diameter of the steel wire rope is relatively large, so the size of the entire hoist is relatively large.

Large appearance, heavy weight, large space occupation, inconvenient installation, and high cost are the obvious shortcomings of the existing hoist hoist
