Detailed description of the invention
Mode below by embodiment further illustrates the utility model, but is not therefore limited among described scope of embodiments by the utility model.
As shown in Figures 1 to 3, the underslung trolley formula grab crane in the present embodiment comprises a grab bucket 9 and for controlling the operating unit 1 that this grab bucket 9 is carried at horizontal surface.
This underslung trolley formula grab crane also comprises a lifting mechanism for driving this grab bucket 9 to hoist, this lifting mechanism comprises a hoisting drum 5, one lifting motor 10 be connected with this hoisting drum 5, one lifting speed reducing 2 be connected with this hoisting drum 5, one hoist brake, this hoisting drum 5 is provided with hoist rope 8, and this hoist rope 8 is connected with this grab bucket 9.
This underslung trolley formula grab crane also comprises a switching mechanism for driving this grab bucket 9 to capture, this switching mechanism comprises an opening and closing reel 5 ', the one opening and closing motor 10 ' be connected with this opening and closing reel 5 ', the one opening and closing reductor 2 ' be connected with this opening and closing reel 5 ', one opening and closing drg, this opening and closing reel 5 ' is provided with opening and closing steel rope 6, and this opening and closing steel rope 6 is connected with this grab bucket 9.
This hoisting drum 5 and this opening and closing reel 5 ' are for be arrangeding in parallel.
This lifting motor 10, this opening and closing motor 10 ', this lifting speed reducing 2 and this opening and closing reductor 2 ' are equipped with a primary heater (not shown), when temperature is lower than design temperature, primary heater starts to prevent this lifting speed reducing 2 and this opening and closing reductor 2 ' to be damaged by frost, and guarantees its serviceability.
