Description

Flat pushing type screw hoist Technical Field The utility model relates to the technical field of screw openers, in particular to a horizontal pushing type screw openers. Background The flat-pushing screw hoist is a special machine for hydraulic engineering, and is mainly used for small reservoirs, channels, pump stations, sewage treatment, water conservancy and hydropower, municipal construction, aquaculture, farmland hydraulic construction engineering and other scenes, and the gate is opened and closed through screw rod transmission. The manual flat-pushing screw hoist is used in a plurality of days, and the screw hoist is controlled to lift due to the fact that the screw hoist is required to be controlled, so that a screw lifting opening cannot be installed for sealing protection, inner parts of the hoist are easy to rust and corrode due to rainwater entering the hoist in rainy and snowy weather, abrasion is aggravated, and the service life of the hoist is shortened. Disclosure of utility model The utility model aims to solve the problems that the screw lifting opening cannot be installed for sealing protection because the screw lifting opening is controlled by controlling the hoist, and internal parts are easy to rust and abrade when rainwater enters the hoist in rainy and snowy weather, so that the service life of the hoist is shortened.
