Description

Locking mechanism of bottom cross shaft steel dam gate

Technical Field

The utility model relates to a hydraulic engineering technical field, concretely relates to locking mechanism of end cross axle steel dam gate.

Background

The rotary steel gate with the cross shaft at the bottom of the steel dam is a novel, attractive and used steel gate for the profile steel of the barrage dam, and the main control principle is that the cross shaft is controlled to rotate through a hydraulic device arranged in hoist chambers on two sides of a river channel, so that a gate leaf is driven to rotate, the gate leaf is toppled to the downstream during flood discharge, and the river channel is closed during water storage. Compared with the traditional rubber dam, the service life of the steel dam bottom cross shaft rotating steel gate is greatly prolonged, and remote control can be performed through a sensor. In addition, the opening and closing time of the steel dam bottom cross shaft rotating steel gate is short, the opening and closing of the gate can be completed generally only in more than ten minutes, the overflow amount can be regulated and controlled as required, and the sudden flood can be effectively guaranteed to discharge flood in time. The gate runs to the required height of blocking water, under the condition of cutting off power, the gate can reliably stay at the required position for a long time, although the driving oil cylinder can be locked by adopting elements such as a hydraulic lock, the hydraulic locking is unreliable after the power source is cut off due to the influence of leakage inside and outside the oil cylinder, and therefore the locking problem of the gate is related to the safety and the reliable running of the water gate.

The utility model patent with application number CN201721879770.3 discloses the following technical scheme of "a crank arm locking mechanical system of bottom shaft drive steel gate": a crank arm locking mechanism of a bottom shaft driven steel gate comprises a hoist cylinder arranged in a hoist chamber and hinged on a cylinder hinged support, wherein a piston rod of the hoist cylinder is extended to be hinged with one end of a crank arm, the other end of the crank arm is fixed with a bottom shaft, the bottom shaft is rotatably arranged in the bottom shaft hinged support, a gate leaf is arranged on the bottom shaft, a locking mechanism is arranged in the hoist chamber and comprises a locking seat and a first side plate and a second side plate which are arranged on the locking seat at intervals, a support is arranged on the outer side of the first side plate, a linear driving mechanism is fixed on the support and connected with a positioning pin, the axis of the positioning pin and the rotary surface of the center of the crank arm are positioned in the same plane, a locking plate is fixed on the crank arm, locking holes are formed in the locking plate, the first side plate and the second side plate, and when the gate leaf is positioned at a position needing to be locked, the locking plate is located between the first side plate and the second side plate, the positioning pins are opposite to the positions of the three locking holes and can be inserted into the three locking holes, and a detection component for detecting the positions of the positioning pins is further arranged on the locking mechanism.

According to the scheme, the crank arm and the gate are locked by matching the positioning pin and the three locking holes, the stress is balanced, the structure is stable, and the locking seat is in a fixed state and cannot be locked at any angle; however, the existing urban water gate not only needs to meet the requirements of flood control, water diversion and navigation, but also needs to control the angle of the gate according to the water level and form the landscape effect of artificial waterfall by utilizing the water passing from the top of the gate door; therefore, the locking mechanism with a single angle cannot meet the use requirement, and a novel locking mechanism is very necessary to be developed.
