Hydraulic-drive winch hoist

Abstract

The invention discloses a hydraulic-drive winch host. The hydraulic-drive winch hoist comprises a rack, a reel, a steering pulley set, a balancing pulley set, a steel wire rope, rigging lantern rings, a hydraulic system, an electrical control system and the like. A hydraulic motor with a hydraulic brake is used in the hydraulic system. The hydraulic motor, the reel and a safety brake are installed on the rack. One end of the reel is provided with the hydraulic motor in power connection with the reel, and the safety brake in power connection with the reel is installed at the other end of the reel. One end of the steel wire rope is fixedly connected to the rack through one corresponding rigging lantern ring, and the other end of the steel wire rope is sequentially wound around the steering pulley set and the balancing pulley set, is wound on the reel and is finally fixedly connected to the reel through one corresponding rigging lantern ring. During stopping or a power failure, the two ends of the reel need to be braked at the same time and cannot be affected by warping of load inertia moment, and therefore braking can be more stable and more effective; the system pressure is set through an overflow valve, overloaded driving force cannot occur, and it is ensured that the phenomena that the steel wire rope is broken and a gate is stuck cannot happen; and the structure is compact, and the civil engineering is simplified.

Description

technical field [0001] The invention relates to the technical field of hoist in the water conservancy and hydropower industry, in particular to a hydraulically driven winch type hoist. Background technique [0002] At present, in the water conservancy and hydropower industry, the hoist hoist has been widely used. This hoist hoist directly drives the reducer, open gear pair, reel, and wire rope to lift or close the water conservancy and hydropower project. The gate in the middle; this kind of hoist hoist with pure mechanical transmission is a technology introduced from the former Soviet Union in the 1950s, and the domestic design and manufacture is still used today. [0003] Of course, hoist hoist technology has been continuously perfected, advanced and developed for decades. The current hoist hoist has made great progress in terms of material application, mechanism improvement, safety guarantee and automatic control means. Even so, there are still some technical deficienci...

Problems solved by technology

[0008] The technical problem to be solved by the present invention is to provide a hydraulic drive hoist hoist to solve the existing hoist hoist: when the rigid gear transmission chain is damaged, the gate cannot be protected by the brake. ; The reel is easy to run beyond the limit stroke, causing the steel wire rope to be twisted in reverse or the gate is stuck to the upper limit, and the steel wire rope is damaged or broken; and the problem is that the shape and structure are huge and the amount of civil engineering is large.
