A rain-shielding device for an open-air storage yard and its application method

Abstract

The invention discloses a rain shielding device used for an open storage ground. The rain shielding device comprises rain shielding canvas, an arc portal and a plurality of operating mechanisms used for supporting and driving the portal. Hanging rings are arranged on the rain shielding canvas, two sets of electric hoists distributed in rows are arranged on the portal, and lifting hooks on the electric hoists are connected with the hanging rings; the operating mechanisms are in a tire type, and every tire type operating mechanism comprises a frame, a balance beam, a positioning pin, wheels, a three-in-one speed reducer, a chain transmission component and a cable winding device, wherein the balance beam is arranged at the top of the frame, the positioning pin is used for fixing the balance beam and the frame, the wheels are arranged at the bottom of the frame, the three-in-one speed reducer is arranged on the frame, and the chain transmission component is used for connecting the three-in-one speed reducer and the wheels. The invention further discloses a usage method of the rain shielding device used for the open storage ground. By the adoption of the rain shielding device and the usage method, the rain shielding canvas is pulled through the portal and covers the storage ground, goods stacks are used for supporting the rain shielding canvas, and the amount of labor is reduced; rapid storage ground transferring is achieved by using the operating mechanisms, and operation is convenient.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a rain-shielding device for an open-air storage yard and a method for using the rain-shielding device for the open-air storage yard. Background technique [0002] At present, in order to reduce capital investment, many grain terminals in China use the method of covering canvas in open yards to store grain. There is such a problem like this: When it rains, the grain should be covered with canvas to prevent the grain from being eroded by rainwater. [0003] At this stage, the wharf is covered manually. In a conventional grain storage yard (60m×40m), using manual covering canvas has problems such as heavy labor, long operation time, low efficiency and rainwater leakage. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a rain-shielding device for an open-air storage yard and a method for using the rain-shiel...
