Description

A kind of new fracturing pump crosshead device
Technical field
The utility model is related to petroleum and natural gas drilling technique field, more particularly to a kind of new fracturing pump crosshead dress Put.
Background technology
Fracturing pump is widely used in petroleum gas pressure break scene, and the large and small head of traditional pressure break pump rod 2 ' is generally all using cunning Dynamic bearing, crosshead pin 5 ' is fixed in the hole of crosshead 3 ', and copper sheathing 4 ' is fixed on small end of connecting rod endoporus, small end of connecting rod and copper sheathing It is assemblied on crosshead pin 5 ', opposing oscillatory between crosshead pin 5 ' and copper sheathing 4 ' during operating;Copper sheathing 4 ' and crosshead pin 5 ' it Between lubricating oil come from big end, lubricating oil enters big end from the axle journal of bent axle 1 ', then by the oil duct in connecting rod A ' enters small end of connecting rod.
The attachment structure of conventional linkage, crosshead, copper sheathing and crosshead pin is limited by crosshead and connecting rod monnolithic case knot The limitation of structure size, copper sleeve inner hole size is small, and width pressure-bearing surface length is only small end of connecting rod width so that fracturing pump Copper sheathing stress is obvious bigger than big end than pressing in the course of work, reliability reduction.The lubricating oil of small end of connecting rod is from company simultaneously Bar major part, lubricating oil oil mass is not enough, and lubricating oil, after big end sliding friction pair, oil temperature has built up, therefore The sliding bearing of small end of connecting rod is relative to the sliding bearing of big end, and the ratio pressure of its sliding bearing is bigger, lubricating oil fuel delivery Less, oil temperature is higher, and these unfavorable factors cause small end of connecting rod sliding bearing an into weak spot of equipment, to the excellent of equipment Change design totally unfavorable.
Utility model content
The purpose of this utility model is:A kind of structure novelty, reliable operation, convenient disassembly, high working efficiency are provided A kind of new fracturing pump crosshead device.
In order to achieve the above object, the utility model provides following technical scheme.
A kind of new fracturing pump crosshead device, it is characterised in that including:
Crosshead, offers big oil groove, oilhole one, oilhole two and oilhole three in the crosshead;
Copper sheathing, the copper sheathing is arranged in the crosshead, through hole is offered in the crosshead and is matched with the copper sheathing, The copper sheathing is made up of left copper sheathing, right copper sheathing and the bearing shell between the left copper sheathing and right copper sheathing, is opened on the left copper sheathing Oil groove one is provided with, oil groove two is offered on the bearing shell, oil groove three is offered on the right copper sheathing;
Briquetting, the briquetting is used for fixing the bearing shell, and the quantity of the briquetting is 2, is respectively used to fix bearing shell Upper and lower two sides, offer N number of screwing through hole on the briquetting, N is the positive integer more than or equal to 2, the correspondence inside crosshead Position offer the screw hole matched with above-mentioned screwing through hole, screw enters described ten through the screwing through hole on the briquetting Be pressed in the briquetting on the bearing shell by the screw hole on prefix, and the bearing shell is fixed, and prevents the bearing shell from rotating.
Used as preferred scheme of the present utility model, the oilhole one connects the big oil groove and the oil groove one, the oil Hole two connects the big oil groove and the oil groove two, big oil groove and the oil groove three, the big oil described in the oilhole tee joint Oil in groove is directly lubricated to the left copper sheathing, right copper sheathing and bearing shell.
Used as preferred scheme of the present utility model, the left copper sheathing and right copper sheathing are arranged on the cross by interference fit Both sides in head, prevent the left copper sheathing and right copper sheathing from being rotated relative to the crosshead, and the bearing shell is solid by the briquetting It is scheduled in the crosshead and is located between the left copper sheathing and right copper sheathing.
Compared with prior art, the beneficial effects of the utility model:
1st, copper sheathing is divided into three parts and is installed, and easy for installation, stock utilization is high, and interchangeability is good and processes simpler It is convenient;
2nd, due to increase connecting rod small-end bearing and crosshead pin contact area so that copper sheathing stress surface increase so that stress ratio Pressure reduces, and the reliability of part is higher;
3rd, lubricating oil is directly lubricated and lowers the temperature into copper sheathing from crosshead to copper sheathing so that drop of the lubricating oil to copper sheathing Gentle lubricant effect is more preferable.
