Portable mechanical disc brake winch

Abstract

The embodiment of the invention discloses a portable mechanical disc brake winch, and particularly relates to the technical field of winches. The portable mechanical disc brake winch comprises a mainmachine seat, wherein a motor is fixedly arranged at the top end of the main machine seat, a rope barrel plate is fixedly arranged at the output end of the motor, a rope barrel pipe is fixedly arranged at the front end of the rope barrel plate, a mechanical clutch mechanism and a mechanical disc brake mechanism are arranged at the front end of the rope barrel pipe, and the mechanical clutch mechanism and the mechanical disc brake mechanism are both arranged at the top end of the main machine seat. According to the portable mechanical disc brake winch, the mechanical clutch mechanism is tightlycombined with the rope barrel pipe, slipping-off cannot occur; the mechanical disc brake mechanism is adopted, the oil brake is abandoned, the problem of ineffective brake generated by oil leakage and maintenance is avoided, brake is sensitive and reliable, the service life is long, the maintenance is free; and waist-shaped holes are designed so that the friction force between a disc brake pad and a brake disc on a disc brake assembly can be adjusted, and an operator can easily drag and pull a lifting hook of a lifting machine to hook remotely in the clutch state.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of winches, in particular to a portable mechanical disc brake winch. Background technique [0002] In the construction of construction, decoration and installation projects, various materials need to be lifted vertically upstairs, and the equipment to be installed also needs to be lifted vertically into place, which requires the use of a portable hoist. Machines for objects can be divided into boom type hoist, mobile hoist, straight type hoist, and full-angle type. The hoist used on the hoist is a light and small lifting device that uses a reel to wind a wire rope or chain to lift or pull heavy objects. It is also called a winch. The hoist can lift weights vertically, horizontally or obliquely. There are two types of electric winches. [0003] The disadvantage of the existing public portable hoist is that the hoist part is inconvenient to carry. The hook is randomly placed when it is ...

AI Technical Summary

Problems solved by technology

[0003] The disadvantage of the existing public portable hoist is that the hoist part is inconvenient to carry, and the hook is placed randomly when storing, resulting in loose wire ropes, and it is easy to bruise fingers during handling. There is currently a hoist main rope on the market. The barrel adopts a mechanical clutch, and the brake part uses brake bands and brake pads. The brake band is easy to break after fatigue, resulting in a great safety hazard. Moreover, the rope drum is in the clutch state, and the brake band has no controllable and suitable friction force, which may easily cause the rope drum to be messed up. Rope, which affects safety and work efficiency, the braking torque of this brake device is extremely limited; there is another one on the market that uses a similar principle to a car clutch and uses friction, which can be used for both clutch and brake. This clutch is also in the clutch state. However, it is also impossible to fully control the appropriate strength, resulting in messy ropes and immobility, which affects the user experience, and requires frequent maintenance in the later period. Most of the users of small cranes are migrant workers. Occurrence of major safety accidents
