Eccentric hingeless curved steel gate structure

Abstract

The invention discloses an eccentric, hingeless and arc-shaped steel gate structure, which comprises an eccentric, hingeless and arc-shaped steel gate, wherein the top end of the eccentric, hingeless and arc-shaped steel gate is connected with a hydraulic rod of a hydraulic cylinder through a lug; dam bodies at the two sides of eccentric, hingeless and arc-shaped steel gate are respectively provided with an arc-shaped track slot corresponding to the eccentric, hingeless and arc-shaped steel gate; and the two sides of the eccentric, hingeless and arc-shaped steel gate are symmetrically provided with multiple idler wheels rolling along the arc-shaped track slots. In the opening process of the gate in the invention, an arc-shaped panel of the gate and sludge are separated, thus reducing the friction between the arc-shaped steel gate and the sludge in the opening process and inhibiting the gate opening force from being increased due to sedimentation of sludge in front of the gate; and as the eccentric, hingeless and arc-shaped steel gate is in a hingeless support type, the weight of the whole arc-shaped gate is reduced. The eccentric, hingeless and arc-shaped steel gate structure has lowered construction cost of the arc-shaped steel gate.

Description

technical field [0001] The invention relates to a curved steel gate. In particular, it relates to an eccentric hingeless arc steel gate structure capable of reducing the frictional force of silt on the arc steel gate. Background technique [0002] The door leaf of the arc-shaped steel gate can be rotated around the fixed horizontal hinge shaft by the traction of the opening and closing machine. To open the door in clear water, it only needs to overcome the self-weight of the gate and the resistance moment of the frictional resistance of the water stop and the hinge shaft to the hinge shaft. The opening and closing of the curved steel gate is labor-saving, rapid and reliable. At the same time, it can close a relatively large orifice size according to the needs of the project; the pier thickness of the curved steel gate is smaller. Compared with the plane gate, the opening and closing force is smaller. The number of embedded parts is small. Therefore, arc-shaped steel gates ...

AI Technical Summary

Problems solved by technology

During the opening process, the curved steel gate and the silt 7 are always in a sliding friction state. The opening force varies with the thickness and duration of the silt 7 in front of the door. It is difficult to determine the capacity of the gate hoist. Accidents caused by sedimentation, overloading the gate hoist, and affecting normal opening
