Description

A steel gate with middle hinge

[technical field]

The invention relates to the technical field of gates in water conservancy projects, in particular to an upward-turning steel gate with a middle hinge.

[Background technique]

The hydraulic steel gate is one of the important components of the hydraulic structure. It can close the opening of the building according to the needs, and can also open the opening completely or partially to adjust the water level and flow of the inner and outer rivers, so as to obtain flood control. , irrigation, water supply, power generation and navigation and other benefits, but also can provide the necessary conditions for the maintenance of related buildings and equipment. The gates are usually set at the inlets and outlets of water intake and transportation buildings, etc., and the gates can be opened and closed flexibly and reliably to exert their functions and benefits and maintain the safety of the buildings. There are many types of hydraulic steel gates, and there are many classification methods. According to the structural characteristics of the gates, they can be divided into plane straight-up doors, rising doors, curved doors, miter doors, double-leaf doors, etc. The plane straight lift door is the most widely used door type in hydraulic structures. It has the advantages of simple structure, convenient and reliable operation and low cost. However, the conventional planar lift gate requires a high upper bent frame and hoist room, especially for a single building, which is difficult to coordinate with the surrounding environment, and requires a taller and thicker gate pier; it has a gate slot that affects water flow, especially When the water head is high, the existence of the gate slot will bring a lot of trouble, and more embedded parts are required; after the gate is lifted, it is suspended above the orifice, which limits the navigable height, and the dripping water of the gate also affects passing ships, and the visual effect is relatively poor. Poor; In addition, the head of the hoist required by this structure is also relatively large.

Due to the above-mentioned shortcomings of the plane straight-up gate, there are also upturned steel gates in the prior art, such as the Sancha River estuary sluice used in the Nanjing Huaihe River Improvement Project, which solves the problems of poor visual effects of the plane straight-up gate. , its structure is supported on the foundations on both sides. After the gate is opened, it can form a certain landscape effect and can prevent floods and tides. However, the structure of this design is complicated, there are many embedded parts, and the investment cost is relatively high.

In the prior art, there is a hydraulic upturning gate such as the publication number CN 101666076, which includes a gate, a hydraulic hoist, a hydraulic pump station and a control room. The gate is composed of three or more unit gates arranged horizontally. The unit gate Odd numbers are A-type doors, and even-numbers are B-type doors. Each A and B-type door and the upper head of the oil cylinder of the hydraulic hoist are respectively hung on the two boxes added upstream and downstream of the isolation belt between double-width bridges through hanging hinges. On the opposite side of the type steel structure beam, the middle part of each A and B type door is respectively connected with the lower head of each hydraulic hoist through a support hinge; the side water stop rubber pressure on both sides of each B type door On the door leaf of the adjacent A-type door, the bottom water-stop rubber on the bottom and rear side of each A and B-type door is pressed on the side of the bottom sill to form a lateral and bottom sealing structure, so that large-span gates can be built , without obstructing the landscape. This structure is suitable for large-span openings without gate pier intervals, which need to be built on the basis of double-width bridges; the door leaves are arranged in a vertical direction, which is not conducive to the flow of water; each opening is composed of multiple door leaves and multiple sets of openings. Not only the water-stop device of the gate is complex, but also must be opened or closed according to a certain operation sequence; the gate has no support arm structure, and the rotation center is located at the top of the gate, and the resulting opening and closing force is relatively large; the position of the gate after it is fully opened It is basically determined by the height of the door leaf. When the gate is required to be in a higher position after being fully opened, it may require a higher door leaf and cause waste; each gate needs 2 sets of different hydraulic locking devices when it is fully opened or fully closed. , one set is located underwater, the operation accuracy is difficult to control and the maintenance is inconvenient; the lifting lug device is set in the middle of the door leaf, and the piston rod of the hydraulic press is soaked in water for a long time, which has an adverse effect on the opening and closing equipment; in addition, the design of the bottom sill leads to The bottom of the door is prone to silting, and an additional set of scouring and silting equipment is required.
