Description

A kind of the AC frequency conversion hoister system and its control method of removal hydraulic disc brake
Technical field
The invention belongs to petroleum drilling and mining equipment technology fields, and in particular to a kind of AC frequency conversion winch of removal hydraulic disc brake System and its control method.
Background technology
Classify according to drive form, winch has mechanically powered winch, electrical drawworks and hydraulically-powered winch.It is conventional Winch will configure a set of main brake and add a set of auxiliary brake, i.e., the configuration of two sets brakes.
Main brake refer to can directly active control and brake winch brake.Hydraulic disc brake is big with its braking capacity, Reliability and it is safe, brake sensitivity is high, remote-controlled, labor intensity is low, brake thermal diffusivity is good and thermal stability forms well For the standing main brake of various drilling machines.Hydraulic disc brake has service braking, emergency braking, parking braking, anti-collision four kinds of work(of braking Energy.
In recent years, domestic AC frequency variated rig development quickly, has winch, turntable variable speed, AC frequency conversion system Digitlization accurately controls, the advantages that automating, is intelligent of drilling machine easy to implement.But pass through the study found that becoming for exchange For all electric system configuration of frequency drilling machine, winch is equipped with hydraulic disc brake and also needs to increase additional hydraulic pressure new system:Hydraulic station, Hydraulic valve bank etc. both occupies floor space, increases weight, and bring additional cost payout, and influence AC frequency variated rig All electric system in terms of integration utilize.
Invention content
The object of the present invention is to provide a kind of the AC frequency conversion hoister systems and its control method of removal hydraulic disc brake, from strand The comprehensive mesh for realizing AC frequency conversion winch removal hydraulic disc brake of bassinet structure, pusher-tray type brake system and control method etc. Mark.
