Radial gate hoist

Abstract

A radial gate hoist belongs to the technical field of hydraulic and hydro-power engineering equipment. The radial gate hoist comprises a motor, a reducer, a winch, and a steel wire rope connected with a radial gate, wherein the motor provides power and is connected with the reducer through a gear, the winch is connected with the reducer through a gear rod piece, a rope groove for preventing the steel wire rope from displacing is arranged in a winding drum surface of the winch, the cross section of the rope groove takes the shape of a semicircle, a plurality of track guide devices are arranged among gate piers in the steel wire rope, the steel wire rope penetrates through the track guide devices, the track guide device is provided with an automatic steel wire rope maintenance device, and an automatic rope hole closing device is arranged on a bottom board of an on / off chamber. The radial gate hoist solves the problems in the medium and large water conservancy projects that the maintenance difficulty of the steel wire rope of the radial gate hoist is high, and an operator also has potential safety hazards as a certain sized rope hole is left on a plane of the bottom board of the on / off chamber. The radial gate hoist which is simple in structure, is automatically maintained, and is safe to operate, and whose rope hole is automatically closed is provided.

Description

technical field [0001] The invention relates to a hoist, in particular to an arc gate hoist, belonging to the technical field of water conservancy and hydropower engineering equipment. Background technique [0002] In water conservancy and hydropower projects, the lifting machinery used to control gates, trash racks and other equipment is called hoist. There are two forms of power transmission of the hoist: hydraulic transmission and mechanical transmission. The hydraulic transmission is stable, but the structure is complex. When double lifting points are used, the oil pressure in the two hydraulic cylinders needs to be the same. When the gate opening is large, the piston rod It will be very long, and the seal of hydraulic components is prone to leakage. There are screw type, winch type and other types of mechanical transmission. Screw type transmission has low efficiency and is easy to wear, so it is generally used in small water conservancy projects. The hoisting type a...

AI Technical Summary

Problems solved by technology

The screw transmission efficiency is low, easy to wear, generally used in small water conservancy projects

The hoisting type adopts the type of wire rope, mostly with double lifting points, and is generally used in large and medium-sized water conservancy projects, but the maintenance of the wire rope is difficult; when the gate is opened and closed, the trajectory of the wire rope on the bottom plate of the hoist chamber is curved, and it needs to be installed on the bottom plate. A rope hole of a certain size is reserved on the top, which poses a safety hazard to the operator

[0003] Chinese patent 201220062613.4 relates to an arc gate hoist, the driving device drives the drive gear set to work through the reducer, the drive gear set drives the gear rod to lift, and the gear rod drives the connecting rod connected with the arc gate to realize the gate opening and closing; the structure is simple , but based on the force characteristics of the rod, there is an increase in the lifting height of the hoist, the moment arm of the lifting point becomes smaller, and the hoisting force increases, which will aggravate the wear of the gears in the gear bar and the drive gear set; for the gear bar The structure and quality requirements of the movable link with the connecting rod are also particularly high; the lifting point is set on the plate surface of the arc gate, which has a certain impact on normal use
