Description
Technical field
The utility model relates to oil drilling and extracting equipment technical fields, and lifting system is worn before being particularly used for drilling machine raising
Draw a kind of telescopic wire rope handling guide pulley device of drilling line.
Background technique
Rotation lift-type is a kind of common oil-well rig raising form, and is widely used in deep-well and ultra-deep well rig.Rotation rises
Before churn raising, most important preparation first is that drilling line is worn between crown sheave group and tourist bus pulley blocks
Lead plate is around in place.
Drilling line diameter is often larger, and flexibility is poor, in wire rope handling operation, must first connect rope, i.e. diameter is smaller soft
The better wirerope of toughness.Messenger successively bypasses the fast rope sheave of A-frame, overhead traveling crane fast line first from the messenger roller rope stretching of rope rewind machine
Wheel, into crown sheave group, is then coiled between crown sheave group and tourist bus pulley blocks, finally from crown sheave group rope stretching,
Enter the dead line anchor for being fixed on derrick leg.Messenger by messenger rope end and is located at rope rewind machine after dead line anchor rope stretching
Drilling line rope end on another roller connects together securely.The rotation of rope rewind machine roller, returns and drags messenger, drilling line is suitable
The route of messenger successively put on each pulley and pulley blocks；After drilling line rope sheave fast across A-frame, unlocks and draw
Rope, drilling line rope end is wound on the winch drum of pedestal table top, and wire rope handling operation is completed.
Since the fast rope sheave of A-frame is in the top of A-frame cross bearer, and rope rewind machine is in the side that derrick is droped to the ground, messenger from
Rope rewind machine rope stretching, when directly around fast rope sheave above A-frame cross bearer, can and A-frame cross bearer generate friction.Raising is worn
Rope reaches certain number, and A-frame cross bearer can be ground long and narrow groove by wirerope, so that its structural strength is affected, deposit
In serious security risk.In addition, this direct wire rope handling route, when passing through derrick, according to the difference that structure is arranged, back fan
Rigid frame may also generate interference to it.
Utility model content
The purpose of the utility model is to provide a kind of telescopic wire rope handling guide pulley devices, are wearing to avoid before derrick lifting
The friction of wirerope and A-frame cross bearer and derrick back fan rigid frame, guarantees that wire rope handling operation safety efficiently carries out during rope.
In order to achieve the above objectives, technical solution adopted in the utility model are as follows:
A kind of telescopic wire rope handling guide pulley device, it includes hollow fixing pipe, and fixing pipe is vertically welded in drilling machine bottom
On the front-axle beam of seat pipe setback beam, it is located at below pipe setback beam table top, is socketed with telescoping tube, the length of telescoping tube in the inner cavity of fixing pipe
Degree is less than the length of fixing pipe；Fixing pipe and the corresponding position of telescoping tube offer the array pin hole that can be overlapped, in pin hole
Tail cone pin is plugged with to position fixing pipe and telescoping tube；The top of telescoping tube is welded with support, and pulley is connected by pin shaft
On the support.
Preferably, at least 2 groups of the pin hole.
When the utility model is used, being inserted into the position of adjustable pulley in different pin holes by tail cone pin.This is practical new
Type is located at the lower section of pipe setback beam table top, and when working condition can stretch out the edge of pipe setback beam table top, off working state or
It may be withdrawn into when travel position in pipe setback beam mesa edge.
The utility model has the following beneficial effects:
(1) wire rope handling route when the utility model improves drilling machine raising wire rope handling between rope rewind machine and A-frame, avoids steel
The friction of cord and A-frame cross bearer and derrick back fan rigid frame, guarantees that wire rope handling operation safety efficiently carries out；
(2) fixing pipe and telescoping tube are telescopic connection in the utility model, and the pulley position positioned at telescoping tube top can
It adjusts, it is scalable to be retracted within pipe setback beam table top range after the completion of wire rope handling, it is big not change pedestal packaging unit outer dimension
It is small, convenient transportation.

Contracting formula wire rope handling guide pulley device, 9, dead line anchor, 10, tourist bus pulley blocks, 11, rope rewind machine, 12, crown sheave group, 13, day
The fast rope sheave of vehicle, 14, the fast rope sheave of A-frame.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
A kind of telescopic wire rope handling guide pulley device as shown in Figure 1, it includes hollow fixing pipe 1, and fixing pipe 1 is vertical
It is welded on the front-axle beam of rig substructure pipe setback beam, is located at below pipe setback beam table top, be socketed in the inner cavity of fixing pipe 1 flexible
Pipe 2, the length of telescoping tube 2 are less than the length of fixing pipe 1；Fixing pipe 1 and the corresponding position of telescoping tube 2 offer and can be overlapped
2 groups of pin holes 5, be plugged with tail cone pin 3 in pin hole 5 and fixing pipe 1 and telescoping tube 2 positioned；The top of telescoping tube 2 is welded with
Support 4, pulley 6 are connected on the carrier 4 by pin shaft.
Fixing pipe 1 is vertically welded on the front-axle beam of rig substructure pipe setback beam, entire telescopic wire rope handling guide pulley device 8
Below the table top, working condition can spread from the table avris.When pedestal Integral transporting or pipe setback beam individually transport, telescoping tube
2 be retracted state, and two tail cone pins 3 are inserted into two groups of pin holes 5 of fixing pipe 1 and telescoping tube 2 respectively, are fixed, pulley 6 is whole
Body is taken within pipe setback beam table top avris.
Before wire rope handling operation starts, first messenger and drilling line are respectively wound around on two rollers of rope rewind machine 11.
Messenger is from 11 rope stretching of rope rewind machine, before reaching A-frame, initially passes through the cunning of the telescopic wire rope handling guide pulley device of the utility model
Wheel 6, further around A-frame fast line wheel 14, the fast rope sheave 13 of overhead traveling crane is crossed, into crown sheave group 12, then in crown sheave group 12 and trip
It is coiled between pulley sheave group 10, finally from 12 rope stretching of crown sheave group, enters the dead line anchor 9 for being fixed on derrick leg.Draw
Rope is secured by messenger rope end and the drilling line rope end on another roller of rope rewind machine 11 after 9 rope stretching of dead line anchor
Ground connects together.The rotation of 11 roller of rope rewind machine, returns and drags messenger, drilling line along messenger route successively in each pulley and cunning
It is put in wheel group；Behind drilling line rope sheave 14 fast across A-frame, messenger is unlocked, in place by the winding of drilling line rope end
In on the winch drum 7 of pedestal table top, wire rope handling operation is completed.
Wire rope handling road by the use of the utility model, when improving drilling machine raising wire rope handling between rope rewind machine and A-frame
Line avoids the friction of wirerope and A-frame cross bearer and derrick back fan rigid frame, guarantees that wire rope handling operation safety efficiently carries out.
