Lifting-dropping and rotating actuating unit

Abstract

The invention provides a lifting-dropping and rotation actuating unit which comprises a steel frame. A screw rod is installed inside the steel frame and the lower end of the screw rod is connected with the steel frame in a sliding mode through a bearing. A travel switch is installed above the bearing and a screw nut is installed above the travel switch. The screw rod of the top portion of the steel frame is provided with a big belt wheel, wherein the big belt wheel is connected with a small belt wheel through a tyre. The small belt wheel is connected with a motor which is installed on a motor fixed plate. The upper segment of the steel frame is connected with the screw rod in a sliding mode through a pressure bearing. The lower portion of the presser bearing is provided with a gasket, wherein a ball circle is installed on the end face of the steel frame which is located under the gasket. A switch is installed above the ball circle. The motor drives the belt wheels to move through the belt, and therefore, the screw rod is driven to move. The screw nut moves up and down along the screw rod. When running into the gasket, the screw rod continues to rotate and drives the screw nut to rotate in a horizontal direction. The rotation is stopped when the screw nut runs to the travel switch after rotation of 180 degrees and the motor stops working. When the screw nut moves under the screw rod and the screw nut runs into the travel switch, the motor stops working. The actuating unit has the advantages of being simple in structure and easy to use.

Description

technical field [0001] The invention relates to a lifting and rotating power mechanism, which is used in the lifting and rotating process of a parking platform. Background technique [0002] With the development of the economy, the contradiction between parking land and urban land has become increasingly prominent, and the phenomenon of random parking on the roadside can be seen at will, which not only blocks traffic, but also brings certain safety hazards. Even though the appearance of the three-dimensional garage has alleviated the problem of difficult parking to a certain extent, the existing three-dimensional garage has defects such as huge structure, large floor space, and complicated operation. When some parking areas such as roadsides, factories, and family homes are limited, but only some parking spaces need to be added, building a huge three-dimensional garage not only affects the appearance, but also increases the construction cost of the garage. The emergence of ...

[0002] With the development of the economy, the contradiction between parking land and urban land has become increasingly prominent, and the phenomenon of random parking of vehicles on the roadside can be seen at will, which not only blocks traffic, but also brings certain safety hazards

Although the emergence of three-dimensional garages has alleviated the problem of parking difficulties to a certain extent, the existing three-dimensional garages have defects such as large structures, large footprints, and complicated operations.

When some parking areas such as roadsides, factories, and family homes are limited, but only some parking spaces need to be added, building a huge three-dimensional garage will not only affect the appearance, but also increase the construction cost of the garage.
