Synchronous lifting gate

Abstract

The invention relates to a synchronous lifting gate. The synchronous lifting gate is characterized in that racks (6) with the same modulus and size are separately mounted at the two sides of the downstream surfaces of gate grooves (3), the toothed surfaces of the racks face the upstream surfaces, the mounting positions and elevations of the two racks (6) are identical, gears (5) are separately symmetrically arranged at the two sides of panels (11) not facing water of a gate (10), the gears (5) at the two sides are connected through rigid synchronous through shafts (7), the synchronous through shafts (7) are fixed to the panels (11) not facing water of the gate (10) through shaft support frames (12), the positions of the gears (5) correspond to those of the racks (6), and the gears (5) can walk on the racks (6). According to the invention, the gears with the same size are arranged at the two sides of the panels not facing water of the gate, the racks are mounted at the positions corresponding to the gears of the gate grooves, the gears can move up and down in the gate grooves along the racks, the gears on the same horizontal plane are rigidly connected through the synchronous through shafts, and the gears at the two sides can synchronously move, so that the synchronous lifting of the gate is realized.

Description

technical field [0001] The invention belongs to the field of hydraulic engineering electromechanical equipment, and relates to a large-scale hydraulic gate, which can make the plate gate evenly and synchronously lifted, can replace the currently used large-scale plate gate, and solves the problem of out-of-synchronization on both sides during the gate lifting process. Background technique [0002] As a main water retaining device, doors are widely used in various aspects of water conservancy projects, such as rivers, reservoirs, channels and other parts that need to control the water volume and level. At the same time, it is also widely used in other fields, such as water transportation, Haikou and other fields. In water conservancy projects, the flow rate is generally large, so the gates required are relatively large. For example, the control gates and diversion gates of rivers, the control gates of spillways, and the tide gates of seaports are generally large. The functio...

Problems solved by technology

This kind of common gate has the problem of asynchronous lifting on both sides during the lifting process, which will cause jamming, difficult lifting, and even the gate is stuck and cannot be lifted, resulting in accidents and affecting the safe operation of the project.

The main reasons for this problem are as follows: first, the precision of the gate grooves on both sides is not enough; second, the elongation rate and elongation of the steel wire ropes on both sides are different; third, there is rope climbing on the hoist drum

During the initial installation and subsequent maintenance, the synchronous debugging of the hoisting wire rope is very troublesome
