Description

Technical Field

[0001] The utility model belongs to the technical field of winch-type door openers, and in particular relates to a winch-type door opener motorized pulley mechanism. Background Art

[0002] The winch gate hoist is a kind of opening and closing equipment specially used for operating the fast gate. The fast gate is used to protect the unit or steel pipe. It is usually hung above the orifice. When an accident occurs in the generator, water pump or steel pipe, the water flow can be quickly cut off to prevent the accident from expanding. The closing time of the fast gate should meet the protection requirements for the unit and steel pipe. Generally, the gate hoist is required to close the fast gate within 2 minutes. At the same time, in order to prevent the bottom edge and sill of the gate from being damaged due to violent collision, the fast winch gate hoist should be equipped with a speed limiting device to limit the descent speed of the gate when it approaches the sill to within 5m / min, but there is no speed limit during the descent process, as long as it does not cause damage to the parts of the gate hoist.

[0003] The existing winch-type opening and closing motorized pulley structure is relatively simple and does not have the function of adjusting the inner wheelbase of the movable pulley. When the rope is subjected to force on the surface of the movable pulley, it will move irregularly on the surface rotating shaft of the movable pulley, thereby increasing the friction of the movable pulley and reducing the effect of use. For this reason, we propose a winch-type opening and closing motorized pulley mechanism. Utility Model Content
