Detailed description of the invention
Known in conjunction with Fig. 1 and 2, a kind of Attention problems loop wheel machine, including support unit and lift unit two parts: support unit includes main support 1, main support 1 connects main support base 2, pneumatic capstan winch base 16, arm base 7, auxiliary support adapter 5, variable-amplitude steel wire rope base 14 from bottom to top respectively.
Arm 6 connects arm base 7, Wirerope fixing device 9, arm pulley 8 from bottom to top respectively.Arm 6 is connected to the variable-amplitude steel wire rope base 14 in main support 1 by arm pulley 8, variable-amplitude steel wire rope adapter 13, variable-amplitude steel wire rope group 12, forms suspension arm support mechanism.
Auxiliary supports 3 lower ends and is connected on deck by auxiliary support base 4, and upper end is connected in main support 1 by auxiliary support adapter 5, forms main supporting mechanism.Lift unit includes compressed air hoist 15, and compressed air hoist 15 is connected with main support 1 by pneumatic capstan winch base 16.Compressed air hoist 15 is connected on Wirerope fixing device 9, arm pulley 8 by boom hoist cable 11, gib head and pulley 10, forms lift unit.
Its operation principle is:
Support concept: support unit is divided into main supporting mechanism and suspension arm support mechanism two parts.Main supporting mechanism is by including main support 1, auxiliary support 3, auxiliary support base 4, auxiliary support adapter 5, main support base 2 totally five part.Main support 1 is main load-carrying members, is primarily subjected to loop wheel machine dead weight and vertical stress when hanging thing and part moment of flexure.Support compressed air hoist 15 by pneumatic capstan winch base 16 simultaneously.Auxiliary supports 3 and is mainly used in the side force that dispersion variable-amplitude steel wire rope base 14 place is raw by hanging produce, thus reducing the moment of flexure of main support 1 bottom.Main support 1 adopts direct insertion type of attachment with main support base 2, and contact surface adopts machining, it is achieved loop wheel machine main body spinfunction.Suspension arm support mechanism is by including arm 6, arm base 7, Wirerope fixing device 9, arm pulley 8, variable-amplitude steel wire rope adapter 13, variable-amplitude steel wire rope group 12, variable-amplitude steel wire rope base 14 totally seven part.Arm 6 is main load-carrying members, is primarily subjected to hang the weight of thing, and is delivered to hanging the raw power of produce respectively in main support 1 by variable-amplitude steel wire rope adapter 13, variable-amplitude steel wire rope group 12, variable-amplitude steel wire rope base 14, arm base 7.
Promote principle: lift unit includes compressed air hoist 15, pneumatic capstan winch base 16, boom hoist cable 11, gib head and pulley 10, Wirerope fixing device 9, arm pulley 8 totally six part.Compressed air hoist 15 is for driving power, and boom hoist cable 11 is by being connected on Wirerope fixing device 9 after arm pulley 8 and gib head and pulley 10.By compressed air hoist 15 twist boom hoist cable 11 during lifting, boom hoist cable 11 drives gib head and pulley 10 to reach enhanced feature by arm pulley 8.
