Electrohydraulic control constant tension winch with rope storage device

Abstract

The invention provides an electrohydraulic control constant tension winch with a rope storage device. The winch comprises a winch main body and the rope storage device, wherein the winch main body comprises a main friction drum device assembly, a rope self-adaption pressing device, a transition gear, a rope, an auxiliary friction drum device assembly and an electrohydraulic control system; the main friction drum device assembly comprises a winch hydraulic motor, a speed reducer with a brake, a main friction drum and a main gear; the auxiliary friction drum device assembly comprises an auxiliary friction drum, a supporting end cover and an auxiliary gear; the electrohydraulic control system comprises a multi-way valve set, a main friction drum device assembly balance valve set, a rope presser self-adaption pressure reduction throttling control valve set and a rope storage device balance valve set; and the rope storage device and the winch main body can be of a split structure, the installation position can be determined according to needs, and a user only needs to guide the rope into the rope storage device in use. The electrohydraulic control constant tension winch has the characteristics that installation and use are convenient, safety and reliability are achieved, the working efficiency is high, the rope storage tensioning force can be automatically adjusted, and self-adaption oil makeup protection and self-adaption pressing are achieved.

Description

technical field [0001] The invention belongs to the field of construction machinery lifting, traction operation and vehicle rescue, in particular to an electro-hydraulic control constant tension winch with a rope storage device. Background technique [0002] The winch is a lifting and traction device for vehicles or equipment to implement self-rescue and rescue. At present, most of the hydraulic winches used in civil rescue vehicles and military rescue equipment are single cylinder winches and double friction roller constant tension hydraulic winches, among which: [0003] Single-drum winch, which is a reel fixedly connected to the output mechanism of the reducer driven by a motor, and drives the rope (including wire rope, the same below) wound on it to move through the reel to achieve pulling force output. The single-drum winch is in the working process As the winding rope layer changes, the working radius of the reel changes; because the motor speed and output power are f...

Problems solved by technology

This method makes the hydraulic damping decrease or disappear due to the leakage of the valve body when the stretcher stops for too long, and the wires and cables between the rope storage device and the stretcher become loose and slip.
