Description

A portable mechanical disc brake hoist

Technical field:

The embodiment of the present invention relates to the technical field of winches, in particular to a portable mechanical disc brake winch.

Background technique:

In the construction, decoration and installation engineering construction, various materials need to be lifted upstairs vertically, and the installed equipment also needs to be lifted in place vertically. This requires the use of portable cranes, which can be exchanged The machines for objects are divided into boom type hoisting machine, mobile hoisting machine, straight-in type hoisting machine, and full-angle type. The hoist used on the hoist is a light and small lifting equipment that uses a drum to wind a steel wire rope or chain to lift or haul heavy objects. It is also called a winch. The hoist can lift the heavy objects vertically, horizontally or at an angle. The hoist is divided into manual hoists and There are two types of electric winches.

The shortcomings of the existing portable hoisting machine are that it is inconvenient to carry. The hooks are placed randomly when storing, which causes the wire rope to be loose and easy to damage the fingers during transportation. There is currently a hoisting machine main rope on the market. The drum adopts a mechanical clutch, and the brake part uses brake bands and brake pads. The brake band is easy to break after fatigue, causing great safety hazards. Moreover, when the rope drum is in the clutch state, the brake band has no controllable suitable friction force, which will easily lead to the rope drum disorder. Rope affects safety and work efficiency. The braking torque of this kind of brake device is extremely limited. There is also a kind of brake on the market that uses a principle similar to that of a car clutch, and uses a friction method, which can be used for clutch and brake. This kind of clutch is also in the clutch state. It is also impossible to completely control the appropriate force, which leads to messy ropes and inability to move, affecting the user experience, and requires later maintenance.
