Specific embodiment
Structure, ratio, size depicted in Figure of description etc., only to coordinate the revealed content of specification, with
Understand for those skilled in the art and read, be not limited to the enforceable qualifications of the utility model, therefore do not have skill
Essential meaning in art, the modification of any structure, the change of proportionate relationship or the adjustment of size are not influencing the utility model institute
Under the effect of generating and the purpose that can reach, the model that can cover in the revealed technology contents of the utility model should all be fallen
In enclosing.Meanwhile cited such as " on ", " under ", "front", "rear", " centre " term in this specification, it is merely convenient to describe
Understand rather than to limit the enforceable range of the utility model, relativeness is altered or modified, without substantive change
Under technology contents, when being also considered as the enforceable scope of the utility model.
As Figure 1-Figure 4, the utility model discloses the sash weight winch structure on a kind of pile driving barge, and sash weight winch 1 includes
Stent 11 and roller 12, roller 12 are located at by support bracket on stent 11, and roller 12 is equipped with twisted rope (generally steel wire rope),
The roller 12 is driven by motor 5, and the end of the roller 12 is equipped with brake hub 13.The winch 1 is equipped with main brake
Structure 2, main brake structure 2 are 1 original conventional structures of sash weight winch, and disk type brake may be used, and belt can also be used to stop
Vehicle does not do excessive statement.The utility model further includes auxiliary brake structure 3, and auxiliary brake structure 3 includes encoder 31, oil cylinder
32 and brake ribbon 33, the encoder 31 is connect with 32 circuit of oil cylinder and then control cylinder piston rod is flexible, on encoder 31
Equipped with for detecting the detection structure 311 of drum rotation speed, brake ribbon 33 is located at the excircle of brake hub 13, the oil cylinder 32
Cylinder body is fixed on stent 11, and brake ribbon 33 is hinged on stent 11, and the piston rod and brake ribbon 33 of the oil cylinder 32 are hinged, oil
Brake ribbon 33 is pushed to rotate when the piston rod of cylinder 32 stretches out and then brake ribbon 33 is allowed to be contacted with brake hub 13 and realize braking action.
With reference to Fig. 1-Fig. 5, operation and use principle of the utility model on pile driving barge are as follows：
(1) pile driving barge 100 is travelled to pile driving position, and pile frame 102 is erected, crab 101 by stake 200 sling and with stake
Frame 102 coordinates, and pile monkey 103 and pile cover 104 slowly fall under the lifting of sash weight winch 1, and pile cover 104 is sleeved on the upper end of stake 200.
(2) crab 101 and sash weight winch 1 put rope simultaneously, make stake 200, pile cover 104 and pile monkey 103 by gravity edge
Longkou track on pile frame 102 falls, and pile top buries after stopping, the hoisting line in stake 200 is unlocked, sash weight winch 1 open from
Clutch off the row opens main brake structure 2, start pile monkey 103 and start to drive piles.Before this, auxiliary brake structure 3 is non-always
Working condition.
