A double-hanging fixed winch

Abstract

The invention provides a double-hanging fixed winch, which includes a frame, a driving mechanism, and a winding mechanism; the driving mechanism, winding mechanism, braking mechanism and installation mechanism are respectively installed on the frame; the driving mechanism It is in transmission connection with the winding mechanism, and the driving mechanism is used to drive the winding mechanism so that the winding mechanism can rotate around its own central axis for winding and / or releasing the traction rope; it also includes a braking mechanism and Installation mechanism; the brake mechanism includes a first brake disc and a second brake disc; a bump is provided on the side of the first brake disc close to the second brake disc; one side of the second brake disc is connected to the second brake disc One end of the winding mechanism is fixedly connected. In the present invention, a protrusion is provided on the first brake disc, and an annular groove is provided on the second brake disc. When the surfaces of the first brake disc and the second brake disc are attached, the protrusion and the annular groove are also attached. The friction contact area between the two is increased, and the braking effect is increased.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, in particular to a double-hanging fixed winch. Background technique [0002] A hoist is a light and small lifting device that uses a drum to wind a traction rope to lift or pull heavy objects, also known as a winch. Hoists are mainly used in material lifting or flat towing operations in construction, water conservancy projects, forestry, mines, docks, etc. The hoist can be used alone, such as a mobile hoist; the hoist can also be used as a component of large mechanical equipment, such as a fixed hoist. [0003] The hoist is divided into two types: single hoisting point hoist and double hoisting point hoist. The double hoisting point hoist is to connect two single hoisting point hoists together through the connecting shaft for synchronous operation. For example, when lifting a large waterway gate, it is necessary to use a double hoisting fixed hoist so that the gate can be lifted an...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the existing double-suspension fixed hoist usually has the following disadvantages: the contact area of ​​the brake disc is small, resulting in poor braking effect; The stability of the bolt fixing method is not high, easy to loosen, and has potential safety hazards;

[0005] At the same time, in the process of mechanical failure, the heavy objects in the hoisting will fall, which causes a certain degree of danger.
