Abstract
The utility model relates to a petroleum engineering equipment field, concretely relates to winch, including a speed change gear, the cylinder, a speed change gear output shaft, first bearing, second bearing, a speed change gear output shaft extend connects cylinder, a first bearing and a speed change gear output shaft, a second bearing and a speed change gear output shaft. This kind of structure has reduced the volume, has alleviateed weight, has prolonged life, has reached reduce cost, the purpose of raising the efficiency.
Description
Technical field
This utility model is related to petroleum works apparatus field, and in particular to a kind of winch.
Background technology
At present, hoist gearbox of petroleum drilling machine output shaft couples general using independent tooth-like shaft coupling with the transition of drum shaft
Device, the axial length dimension and weight shared by this layout structure is all very big, during for structure and limited space, increased
Design difficulty, accordingly increases rig size, poor for applicability for marine mining platform；Also have using gear-box and drum shaft
Associated mode is to reduce space length, however, due to the bearing alignment error of cylinder two, particularly cylinder is worked in high-speed rotation
Cheng Zhong, due to being subject to cable radial pull for a long time, makes drum shaft produce flexural deformation, and deformation causes to the drum shaft and above tooth
Roller box drive system produces destruction, greatly reduces reliable transmission, shortens service life, improves use cost.
Utility model content
In view of this, it is necessary to which a kind of a kind of convenient winch is provided.
A kind of winch, including
First speed change gear；
First transmission output shaft；
Cylinder；
It is characterized in that：
First transmission output shaft extends the connection cylinder.
A kind of described winch, it is characterised in that：
Also include
Clutch shaft bearing；
Second bearing；
The clutch shaft bearing connects first transmission output shaft；
The second bearing connects first transmission output shaft.
First speed change gear is planetary reduction gear.
A kind of winch, including：
First speed change gear；
First transmission output shaft；
Rope draw off gear；
Second speed change gear；
First transmission output shaft extends the connection rope draw off gear；
First transmission output shaft extends connection second speed change gear.
A kind of described winch, it is characterised in that：
Also include
Clutch shaft bearing；
Second bearing；
The clutch shaft bearing connects first transmission output shaft；
The second bearing connects first transmission output shaft.
First speed change gear is planetary reduction gear；
Second speed change gear is planetary reduction gear.
As a result of above-mentioned technical proposal, the beneficial effects of the utility model are：
Volume is this arrangement reduces, weight is alleviated, service life is extended, reduces cost has been reached, efficiency is improved
Purpose.

103 extend connection rope draw off gear 70, and the first transmission output shaft 103 extends the second speed change gear 50 of connection, first axle
Hold 101 to be connected with the first transmission output shaft 103, second bearing 102 is connected with the first transmission output shaft 103, two
Motor 40 is connected with the first speed change gear 10, and two motors 60 are connected with the second speed change gear 50.
First speed change gear 10 is planetary reduction gear and carries two grades of gearshifts.Second speed change gear 50 is planetary reduction gear
Device simultaneously carries two grades of gearshifts.
Rope draw off gear 70 includes cylinder 20, and brake gear 30, cylinder 20 is connected with brake gear 30.
As a result of above-mentioned technical proposal, the beneficial effects of the utility model are：
This structure reduces spring bearing by coaxial connection, reduces volume, alleviates weight, extends and uses
In the life-span, reduces cost is reached, put forward efficient purpose.
In a word, preferred embodiment of the present utility model is the foregoing is only, it is all not to limit this utility model
Any modification, equivalent and improvement made within spirit of the present utility model and principle etc., should be included in this practicality
Within new protection domain.
