Description

Technical Field

[0001] This utility model relates to the field of winch-type gate hoisting technology, and in particular to a winch-type hydraulic gate hoisting machine. Background Technology

[0002] A winch-type gate hoist is a hydraulic machinery device that raises or lowers a gate by winding a steel wire rope around a drum. It is widely used in reservoirs, rivers, hydropower stations, and other scenarios, and features reliable structure, flexible operation, and strong load-bearing capacity.

[0003] A search revealed existing winch-type gate hoists, such as the one disclosed in publication number CN218667413U. This winch-type gate hoist allows for more stable fixing of the winch drum. By utilizing the principle that the turbine cannot drive the worm gear, the steel cable is prevented from tightening or loosening arbitrarily, resulting in a more stable gate fixation and safer operation. However, when the winch drum winds up the steel cable, the cable can only be wound at a fixed position on the winch drum. This concentrated distribution of the steel cable can easily lead to cable breakage, affecting the normal winding and unwinding of the steel cable by the winch drum, and thus affecting the normal raising and lowering of the gate. Therefore, a winch-type hydraulic gate hoist is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that when the winch is winding the steel cable, the steel cable can only be wound at a fixed position on the winch. The concentrated distribution of the steel cable can easily lead to cable breakage, which affects the normal winding and unwinding of the steel cable by the winch, and thus affects the normal raising and lowering of the gate. Therefore, a winch-type hydraulic gate opening and closing machine is proposed.

[0026] The winch drum 22 is located on one side of the mounting frame 7. A rectangular opening 11 is provided on the movable plate 6. One end of the steel cable wound on the winch drum 22 extends downward from the rectangular opening 11 after passing through the fixed pulley 8, thereby connecting with the gate below the mounting plate 1.
