Abstract

The invention discloses a single and double hanging point conversion type lifting device which comprises working motors, speed reducers driven by the working motors, and wind drums for winding steel wires, wherein two working motors, two speed reducers and two wind drums are arranged symmetrically; the other end of each of output shafts of the working motors is connected with a synchronizing shaft through a coupling; two synchronizing shafts are connected through an electromagnetic clutch in a transmission mode; and the outer sides of the output shafts of the speed reducers on the ends of the two winding drums are respectively provided with a lifting range indicating device and a position controlling device. The invention has the advantages that after the working motors drive the speed reducers to change speed, the winding drums are driven to rotate and drive a gripping beam and a gate thereof to raise or fall by releasing or extending the steel wires on the winding drums; two mechanisms are connected in the transmission mode through the coupling, the synchronizing shafts and the electromagnetic clutch between the two synchronizing shafts so that conversion between single hanging point and double hanging points and synchronization when operation in double hanging points can be realized; and compared with a lifting mechanism of a conventional gantry crane, one secondary lifting mechanism is saved and the integral structure is simple.

Description

technical field [0001] The invention relates to a two-way door crane for a reservoir, in particular to a single-double lifting point conversion type lifting device for a two-way door crane. Background technique [0002] In power stations of large reservoirs (such as the Xiaolangdi Water Conservancy Project of the Yellow River - Xixiayuan Anti-regulation Reservoir), according to the layout of hydraulic structures, the dam crest gate hoist (hereinafter referred to as the gate hoist) needs to open and close the power station inlet trash rack and its maintenance Gates, open and parapet floodgate accident inspection gates, sand discharge tunnel inlet accident gates, installation room sand discharge tunnel inlet accident gates, sand discharge bottom hole inlet accident gates and diversion sluice accident repair gates, etc., power station water inlet accident inspection and repair The installation and maintenance of the gate and its hydraulic hoist are also operated by this gate ma...
