Oscillating arm type bulkhead gate locking mechanism driven by hydraulic cylinders

Abstract

The invention discloses an oscillating arm type bulkhead gate locking mechanism driven by hydraulic cylinders. A plurality of oscillating arm type bulkhead gate locking mechanism bodies (7) driven by the hydraulic cylinders are successively arranged in the longitudinal direction; each oscillating arm type bulkhead gate locking mechanism body (7) driven by the corresponding hydraulic cylinder comprises a driving oil cylinder (1), an oscillating arm (2), a locking shaft, a shaft sleeve (3), a supporting block (4), a locking supporting track (5) and a step locking rack (6); each driving oil cylinder (1) is assembled below the corresponding oscillating arm (2); the tail of each driving oil cylinder (1) is hinged to a corresponding gate side column hinged support (1.1) arranged on a corresponding gate side column (2.1); and an oil cylinder piston rod (1.2) is arranged on each driving oil cylinder (1). The shortcoming that once functions of a gate lifting device fail, a gate drops to cause serious accidents in the prior art is overcome. The oscillating arm type bulkhead gate locking mechanism has the advantages that the structure is simple, the technology is reliable, each oscillating arm is driven to unfold and fold through the corresponding hydraulic cylinder, and therefore, locking or unlocking during opening and closing of the gate is realized rapidly.

Description

technical field [0001] The invention relates to the field of water conservancy and hydropower engineering, and more specifically relates to a swing arm type flat gate locking mechanism driven by a hydraulic cylinder. Background technique [0002] Vertical ship lifts built on water conservancy and hydropower projects are generally equipped with flat-plate working gates at the upper and lower gates. Usually, the water level of the downstream channel is affected by the tail water of the power station and the flood discharge of the dam, and the water level has a large amplitude and high frequency conversion. In order to meet the normal docking between the ship lift and the lock head, it is necessary to frequently adjust the height of the lock head working door. In order to ensure the normal operation of the ship lift, it is necessary to set up a locking mechanism that can adapt to the changing conditions of the water level of the channel, provide support for the front plate work...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing working doors at the head of the gate adopt hydraulic pin-type locking devices. This kind of device has extremely high requirements on the positioning accuracy of the gate. The gate can only be locked at a certain fixed position in the height direction, and it is difficult to quickly enter and out of lock

It is also possible to use the function of the hoist mechanism itself to lock the working door of the gate head, such as: holding the hydraulic hoist to maintain pressure, fixing the brake of the winch, etc.; this method has high requirements on the performance of the hoist. Once the hoist functions failure, the gate will fall and cause serious accidents
