Steel gate with locking device

Abstract

The invention relates to a steel gate with a locking device. The steel gate with a locking device comprises a door frame, wherein a cross beam is arranged at the upper end of the door frame, a winch opening and closing machine is arranged on the cross beam, a steel gate is arranged in the door frame, and roller wheels are all arranged at the upper end and the lower end of the two sides of the steel gate; longitudinal guide grooves are formed in the two sides of the door frame, the roller wheels are located in the longitudinal guide grooves, a lifting lug is arranged on the steel gate, a steelwire rope of the winch opening and closing machine is connected with the lifting lug, and a V-shaped connecting rod is arranged at the upper end of the inner side of the door frame; and the corner ofthe V-shaped connecting rod is rotationally connected with the door frame through a pin shaft, and an arc-shaped groove matched with the roller wheels is formed in one end of the V-shaped connecting rod. According to the steel gate with the locking device, the structure is simple, the V-shaped connecting rod is additionally arranged, the arc-shaped groove in one end of the V-shaped connecting rodis used for supporting the roller wheels of the steel gate, the steel gate can be effectively locked, steel wire rope suspension is not needed, the safety is high, and the service life is prolonged.

Description

technical field [0001] The invention relates to a steel gate, in particular to a steel gate with a locking device. Background technique [0002] The steel gate is usually used to open and close the movable structure of the water outlet in the local hydraulic structure. It can regulate the flow, control the water level, and transport ships. When the steel gate is opened, the steel gate is lifted by the wire rope of the hoisting machine. After the steel gate is lifted, the steel gate needs to be suspended by the steel wire rope all the time. After a long time, the steel wire rope is prone to disconnection, which leads to the steel gate again. Shut off, low safety and short service life. SUMMARY OF THE INVENTION [0003] In view of the above-mentioned defects, the purpose of the present invention is to provide a steel gate with a locking device which is simple in structure and can automatically lock the lifted steel gate without wire rope suspension. [0004] For this reas...

Problems solved by technology

When the steel gate is opened, the steel gate is lifted up by the steel wire rope of the winch hoist. After the steel gate is lifted, it needs to be suspended by the steel wire rope. After a long time, the steel wire rope is prone to disconnection, causing the steel gate to re-open. Closed gate, low security, short service life
