Double-hoisting-point fixed winch

Abstract

The invention provides a double-hoisting-point fixed winch. The double-hoisting-point fixed winch comprises a rack, a driving mechanism and winding mechanisms; the driving mechanism, the winding mechanisms, braking mechanisms and a mounting mechanism are installed on the rack separately; and the driving mechanism is in transmission connection with the winding mechanisms and used for driving the winding mechanisms so that the winding mechanisms can rotate around their central axes for winding and/or releasing traction ropes. The double-hoisting-point fixed winch further comprises the braking mechanisms and the mounting mechanism; and each braking mechanism comprises a first brake disc and a second brake disc, wherein the side, close to the second brake disc, of the first brake disc is provided with a convex block, and one side of the second brake disc is fixedly connected with one end of the corresponding winding mechanism. According to the double-hoisting-point fixed winch, the first brake disc is provided with the convex block, the second brake disc is provided with an annular groove, when the surfaces of the first brake disc and the second brake disc are attached, the convex block and the annular groove are also attached, the friction contact area of the first brake disc and the second brake disc is increased, and the braking effect is improved.

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.
