Steel dam gate convenient to install

Abstract

The invention discloses a steel dam gate convenient to install, and belongs to the technical field of gates. The steel dam gate convenient to install comprises a bottom shaft. The bottom shaft is supported on a plurality of hinged bases which are fixedly arranged at the bottom of a watercourse. The two ends of the bottom shaft penetrate through walls to be inserted into hoist rooms. A hoist is arranged inside each hoist room. The end portions of the bottom shaft are connected with the hoists through connecting levers. Gate leaves for stopping water are connected to the bottom shaft. The bottom shaft is connected with the walls through sealing supporting pieces. Each hinged base comprises an arc section. The bottom shaft is supported on the arc sections in a rotatable mode. The central angle of each arc section is 90 degrees to 180 degrees. A water stop piece is arranged on one side of the upper stream of the watercourse and abuts against the outer side of the bottom shaft. According to the steel dam gate convenient to install, unit-separating manufacturing according to the number of the hinged bases is not required, the number of the hinged bases can not be limited, a steel dam is wholly placed in the hinged bases after assembly is finished, taking-in-position after the assembly can be achieved, therefore, the assembly construction site and the assembly working space position are free, site installation workloads are greatly reduced, and the steel dam gate convenient to install can easily achieve sealing.

Description

technical field [0001] The invention relates to a water conservancy facility, in particular to a steel dam gate. Background technique [0002] In the prior art, there is a steel dam gate, its structure mainly includes a bottom shaft, the bottom shaft is installed on a plurality of hinge seats fixedly arranged at the bottom of the river, and the two ends of the bottom shaft pass through the wall and extend into the hoist room. There is a hoist in the hoist room, the end of the bottom shaft is connected with one end of the crank arm, and the other end of the crank arm is connected with the extension end of the cylinder piston rod of the hoist, and the door leaf for water blocking is welded on the bottom shaft . When the hoist is working, the crank arm can be used to drive the bottom shaft to rotate, so that the door leaves stand up to block water or fall down to release water. At present, for rivers with a width of tens of meters or even hundreds of meters, gates must be man...

AI Technical Summary

Problems solved by technology

At present, for rivers with a width of tens of meters or even hundreds of meters, gates must be manufactured separately and installed on site. The bottom shaft is welded and connected into unit section components in the factory. During on-site installation, the bottom shaft of the unit section needs to pass through the corresponding hinge seat. Both the bottom shaft and hinge seat are large components, and the operation is difficult during connection. Accurate positioning is very difficult. Difficult; in order to be disassembled and overhauled, the unit segment members can be connected by detachable connection methods, such as connecting adjacent door leaves with bolts, and connecting adjacent bottom shafts with flanges and bolts, because the bottom shaft It is installed through the hinge base, and the two are rotatably supported and connected. The working surface of the hinge base is a complete circle, and the pre-welded flange cannot pass through the hinge base. Therefore, it is necessary to pass through the hinge base. The inner flange is installed in the bottom shaft of the unit section of the first section. After it passes through the hinge seat, the outer flange with an outer diameter larger than the outer diameter of the bottom shaft is installed and connected with the inner flange, and then the adjacent unit section can be connected. The bottom shaft is connected

The problem brought about by this structure is: the use of flange connection, although it is easy to disassemble, but the bottom shaft is set at the bottom of the river, so it is necessary to consider how to seal between the flange and the door leaf, and the outer diameter of the flange is larger than the outer diameter of the bottom shaft. diameter, a step is formed at the flange connection, and the sealing is relatively difficult
