Abstract
A planetary arm power type screwing device for fasteners with screw threads belongs to the technical field of screwing devices used for fixing top nets with top anchor rods in mining tunnels. The planetary clockwork type screwing device is technically characterized in that a composite type gear shaft comprises a driving connector connected with an electric motor and a main gear shaft; one end of the main gear shaft is inserted into the center hole of a screwing device body inlaid with a copper sleeve; a bearing passing through the shaft hole of the screwing device body is arranged at the other end of the main gear shaft; the main gear shaft is connected with the driving connector; four planetary gears with same structure are arranged in the radial direction in the axial middle of the screwing device body; the planetary gears are connected with the screwing device body through pin shafts; and the planetary gears are meshed with the main gear shaft, and are also meshed with inner gear rings sleeved on the screwing device body. The planetary arm power type screwing device has the advantages of safe and reliable operation, stable running, multiple functions, strong interchangeability, simple structure and easiness in onsite maintenance. The driving connector and a screwing connector can be replaced fast, so that the requirements on using different electric motors and different fasteners can be met, and the working efficiency in screwing the fasteners used for fixing the top nets with top anchor rods in a mining tunnel is effectively improved.
