Lifting starting and stopping system for rotating gate

Abstract

The invention discloses a lifting starting and stopping system for rotating a gate, which comprises a drive mechanism for driving a cylindrical gate to forwardly and reversely rotate; the drive mechanism is two lifting starting and stopping machines which are arranged at both shores of a river channel symmetrical to the cylindrical gate; two ends of a winding cylinder of each lifting starting and stopping machine are respectively fixed with a steel wire rope and is reversely wound on the winding cylinder, and the other ends of the two steel wire ropes are respectively connected with the upper part of the cylindrical gate by a plurality of guide slide wheels; a plurality of pulley wheel seats of the guide slide wheels are top / down adjustable structures; and motors of the two lifting starting and stopping machines are in driving connection with the winding cylinder by a speed reducer. The lifting starting and stopping system has the advantages of being simple and compact in structure, and low in manufacture cost, so that the requirement of a urban ecological water system is met, and the aims of flood drainage and flood protection are achieved.

Description

technical field [0001] The present invention relates to a revolving gate, in particular to a hoisting opening and closing system for a revolving gate. Background technique [0002] With the development of the times, the urban ecological water system requires that the overall architectural layout should be organically integrated with the upstream and downstream ecological wetlands and landscape scenic spots, so as to achieve a new urban scenic spot integrating flood control, tourism, leisure and sightseeing. Therefore, the cylindrical gate with beautiful appearance came into being. However, for a river with a large span, the diameter of the cylinder gate should also increase, especially when the diameter of the cylinder gate is more than 50 meters, which requires an opening and closing mechanism with a large driving capacity to complete the gate opening and closing. Turn on and off. For the sake of beauty, the opening and closing mechanism should be set below the ground of ...

AI Technical Summary

Problems solved by technology

For the sake of aesthetics, the opening and closing mechanism should be set below the river bank ground, which limits the installation space of the opening and closing mechanism

The existing hydraulic hoist is used as the rotary opening and closing mechanism of the cylinder gate, which is not suitable due to the limitation of the stroke of the oil cylinder; the combination of the hydraulic motor and the pinion is used to drive the large gear installed on the cylinder gate to rotate, but the gear In addition to its strength requirements, transmission has high requirements on meshing accuracy, tooth surface contact length, manufacturing and installation accuracy of large-diameter ring gears; and the fixing of large-diameter ring gears on the cylindrical gate also makes the gate structure complex and improves Increased manufacturing costs; at the same time, components such as hydraulic motors and gears are not suitable for operation in wet environments
