Description
Technical field
The utility model relates to a kind of derrick accessory equipment, particularly a kind of threading device air winch.
Background technology
Drilling derrick is because its volume is big, Heavy Weight, highly high factor, and its difficulty that hoists and fell is very big, need could accomplish by means of the lift system of complicacy.Generally overhead traveling crane and tourist bus need be installed on Drilling derrick; Overhead traveling crane is the fixed pulley group; Be installed in crown, be made up of parts such as sky vehicle frame, pulley, sheave shaft bearing and auxiliary pulleys, tourist bus pumps in derrick inside; Big rope is worn on request successively on the numerous pulley of overhead traveling crane and tourist bus, the hoisting or falling of the winch big rope realization derrick of traction.Because the length of big rope is long, Heavy Weight; Wearing around need of big rope accomplished by means of messenger; Promptly earlier thin slightly messenger is worn on request on the assembly pulley of overhead traveling crane and tourist bus; The fag end that to restrict greatly again is connected on the messenger, furls the big rope of messenger traction and realizes wearing using steel cable to take out to install to put around, the process need of cable-feeding and assist to accomplish.
The steel cable that uses is at present taken out to install and is put the employing motor-driven, carries out transmission through chain between motor shaft and the messenger winch spool axle, and entire exercise is controlled by electric system, has following weak point:
(1) can transfer the files be merely low speed with two grades at a high speed, infinite speed variation as required in use.Owing in taking out the process of cable-feeding, there are many complicated factors, when crossing tourist bus, overhead traveling crane grooving, be prone to hard extension, hard card phenomenon such as fag end, therefore only not strong with two grades of control of height operability.From security consideration, only use low gear in actual use, it is slower to take out cable-feeding speed.
(2) because steel cable is taken out and installed that to put not be frequent use, add that the field work working environment is relatively poor, the inner member of electric control box breaks down easily, and is stuck such as relay, and button is malfunctioning etc., not easy care.In addition, this equipment adopts chain gear, does not use for a long time to get rusty easily, and is yielding or rupture during use.
(3) situation of closing often appears being difficult to hang in arrangement of clutch, and is in use out of supply easily again, causes uncontrollablely, needs often adjustment.
(4) because the well head of oil well has fire gases to exist; Higher to requirement of explosion; Though the steel cable that uses is at present taken out and is installed the electrical controller of putting explosion proof ratings is arranged, circuit card make moist short circuit, spark phenomenon still appear under the moist rural atmosphere of wind and rain easily, the potential danger of hurting sb.'s feelings is arranged.
The utility model content
The purpose of the utility model is, overcomes the problem that exists in the prior art, provides a kind of and is easy to control and threading device air winch safe, good reliability.
For solving above technical matters, a kind of threading device air winch that the utility model provided comprises air motor, speed reduction gearing and the power transmission flange of band brake handle, and said air motor and speed reduction gearing are fixedly mounted on the same horizontal base; Said speed reduction gearing comprises fluted disc in main shaft, miniature gears one, big gear wheel, Large Gear Shaft During, miniature gears two and the takeoff output; The axis of said main shaft and Large Gear Shaft During is parallel to each other; Said miniature gears one is installed on the said main shaft with the interior fluted disc of takeoff output; The front end of said main shaft stretches out the outer and axle head of the casing of said speed reduction gearing and is provided with spline; The mouth of said air motor is in transmission connection through the spline of spline housing and said main shaft, said miniature gears one and said big gear wheel engagement, and said big gear wheel and miniature gears two are installed on the said Large Gear Shaft During; Said miniature gears two is meshed with the internally toothed annulus of fluted disc in the said takeoff output, and said power transmission flange is fixedly connected on the aft end face of fluted disc in the said takeoff output.
With respect to prior art; The utility model has been obtained following beneficial effect: adopt the air motor driving main shaft to rotate; Main shaft drives miniature gears one rotation, and miniature gears one drives the big gear wheel rotation and realizes slowing down, and big gear wheel drives miniature gears two through Large Gear Shaft During and rotates synchronously; Miniature gears two drives takeoff output internal tooth disc spins and realizes slowing down, and the power transmission flange provides power to threading device; Adopt air motor to do propulsion source and can realize infinite speed variation, no electro spark produces, and turning round does not generate heat can not burn out, the rotating direction can, the ability that adapts to abominable working environment is strong.
