Abstract
The utility model relates to a hand winch brake device. The hand winch brake device comprises a fixing seat fixed onto a winch, wherein a rotation shaft is arranged on the fixing seat; a driving gear is fixed onto the rotation shaft through a bearing; a driving gear brake skin is arranged on the side surface of the driving gear; threads are formed in the rotation shaft; a brake disc is arranged on the fixing seat; a brake disc brake skin is arranged on the side surface of the brake disc; threads are formed in the middle of the brake disc to be matched with the threads in the axis of rotation. Through the structure, when the threads are tightly screwed, the contact of the two brake skins can have the function of brake, safe operation is achieved, the cargo can be hung at any position in the space, the structure is simple, and the operation is convenient and quick.
Description
Technical field
The utility model relates to the one brake in field of mechanical technique, especially relates to a kind of crab winch brake gear.
Background technology
Winch, with the small-sized weight-lifting equipment of reel lay winding wire ropes or chain lifting or traction weight, claims again winch.Winch is can be used alone, also can do lifting, build the road and the machinery such as mine hoisting in constituent elements, because of simple to operate, wiring amount is large, the convenient widespread use of dislocation.Mainly apply to material lifting or flat the dragging of building, hydraulic engineering, forestry, mine, harbour etc.Crab winch operates by manpower, and crab winch is absolutely necessary in some occasions, when needs handling is compared with parcel, likely causes goods to drop, and produces dangerous.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of crab winch brake gear that can conveniently brake and facilitate goods to stop aloft.
The technical scheme in the invention for solving the technical problem is: a kind of crab winch brake gear, comprise the permanent seat being fixed on winch, described permanent seat is provided with a turning cylinder, on described turning cylinder, be fixed with a driven wheel by bearing, the side of described driven wheel is provided with driven wheel brake rubber block, described turning cylinder is provided with screw thread, described permanent seat is provided with a brake disc, described brake disc side is provided with brake disc railway carriage, is provided with the screw thread fit on screw thread and turning cylinder in the middle of described brake disc.
Further concrete, described brake disc and permanent seat are provided with ratchet structure.
Further concrete, described ratchet structure comprises the ratchet being fixed on permanent seat and the ratchet being connected with turning cylinder.
The beneficial effects of the utility model are: after adopting said structure, screw by screw thread, can make the contact of two brake rubber blocks play the effect of brake, can safe in operation and can ensure the skyborne staying at random location of goods, simple in structure, convenient to operation.
