Description
Technical field
The present invention relates to petroleum and natural gas drilling technique field, in particular to a kind of fracturing pump crosshead device.
Background technique
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 usually all using cunning
Dynamic bearing, crosshead pin 5 ' are fixed in 3 ' hole of crosshead, and copper sheathing 4 ' is fixed on small end of connecting rod inner hole, small end of connecting rod and copper sheathing
It is assemblied on crosshead pin 5 ', it is opposite between crosshead pin 5 ' and copper sheathing 4 ' when operating to swing；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 crankshaft 1 ', then passes through the oil duct in connecting rod
A ' enters small end of connecting rod.
Conventional linkage, crosshead, the connection structure of copper sheathing and crosshead pin are limited by crosshead and connecting rod monnolithic case knot
The limitation of structure size, copper sleeve inner hole size is small, and width direction 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, and reliability reduces.The lubricating oil of small end of connecting rod is from company simultaneously
Bar major part, lubricating oil oil mass is insufficient, and lubricating oil, after big end sliding friction pair, oil temperature has built up, therefore
The ratio pressure of sliding bearing of the sliding bearing of small end of connecting rod relative to big end, sliding bearing is bigger, lubricating oil fuel delivery
Less, oil temperature is higher, these unfavorable factors make small end of connecting rod sliding bearing at a weak spot of equipment, to the excellent of equipment
It is totally unfavorable to change design.
Summary of the invention
It is an object of the invention to：A kind of structure novel, reliable operation, one kind that convenient for disassembly and assembly, work efficiency is high are provided
Fracturing pump crosshead device.
In order to achieve the above object, the present invention provides following technical solutions.
A kind of fracturing pump crosshead device, which is characterized in that including：
Crosshead offers big oil groove, oilhole one, oilhole two and oilhole three in the crosshead；
Copper sheathing, the copper sheathing are mounted in the crosshead, and through-hole is offered in the crosshead and is matched with the copper sheathing,
The copper sheathing is made 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
Equipped with oil groove one, oil groove two is offered on the bearing shell, offers oil groove three on the right copper sheathing；
Briquetting, the briquetting are used to fix the bearing shell, and the quantity of the briquetting is 2, are respectively used to fixed bearing shell
Upper and lower two sides offer N number of screwing through hole on the briquetting, and N is the positive integer more than or equal to 2, corresponding inside crosshead
Position offer with the matched screw hole of above-mentioned screwing through hole, screw pass through the briquetting on screwing through hole enter described ten
The briquetting is pressed on the bearing shell by the screw hole on prefix, and the bearing shell is fixed, and prevents the bearing shell from rotating.
As a preferred solution of the present invention, the oilhole one is connected to the big oil groove and the oil groove one, the oilhole two
It is connected to the big oil groove and the oil groove two, big oil groove and the oil groove three described in the oilhole tee joint, in the big oil groove
Oil directly the left copper sheathing, right copper sheathing and bearing shell are lubricated.
As a preferred solution of the present invention, the left copper sheathing and right copper sheathing are mounted in the crosshead by interference fit
Two sides, prevent the left copper sheathing and right copper sheathing from rotating relative to the crosshead, the bearing shell is fixed on by the briquetting
In the crosshead and between the left copper sheathing and right copper sheathing.
Compared with prior art, beneficial effects of the present invention：
1, copper sheathing is divided into three parts and is installed, easy for installation, and stock utilization is high, and interchangeability is good and processing is simpler
It is convenient；
2, due to increasing the contact area of connecting rod small-end bearing and crosshead pin copper sheathing stress surface is increased, thus stress ratio
Pressure reduces, and the reliability of part is higher；
3, lubricating oil directly enters copper sheathing from crosshead and copper sheathing is lubricated and is cooled down, so that drop of the lubricating oil to copper sheathing
Mild lubricant effect is more preferable.
