Background technology
In recent years, demand sustainable growth of the China to oil and gas resource is keeping conventional gas and oil yield steady
While growth, to the larger ultra-low penetration oil field of exploitation difficulty, coal bed gas, shale gas, deep-well oil gas field and deep-sea oil gas money
Source is marched, it has also become the new trend of China's fossil energy exploitation.Compared with the developed countries such as the U.S., the rate of oil and gas recovery in China is total
Body is not high, and room for promotion is larger.Hydraulic fracturing technology is one of the major measure realized oilfield reservoir transformation, increase production stable yields, can
So that oil and gas production increases several times to tens times.With the exploitation of shale gas, core of the fracturing pump as fracturing complete sets of equipment
Part, it is desirable that it is higher and higher, develop towards high pressure huge discharge direction.
The very important parameter for weighing pressure break pump capacity is connecting rod thrust, in the identical situation of pressure break pumpage
Under, connecting rod thrust is bigger, and the pressure that fracturing pump can pump is higher.And the major part for bearing fracturing pump connecting rod thrust is to draw
Bar, connecting rod thrust is up to 100t at this stage, and the endurance of each pull rod is in 25t or so, and this power is pulsating cyclic power, so
Operation field occurs the case where pull rod fatigue fracture, to cause larger loss to client.
Utility model content
A kind of the purpose of this utility model is to provide rigidity high, antifatigue, not broken combined type pressure break pump rod.
To achieve the above object, the utility model uses following technical scheme：
A kind of combined type pressure break pump rod, including pull rod shaft and drag link sleeve；The pull rod shaft include power end connection screw thread,
Positioning table, outer six side, long axis, fluid end connection screw thread, power end connection screw thread, fluid end connection screw thread are located at pull rod shaft
Both ends, close to power end connection screw thread, outer six side is set between positioning table and long axis positioning table, and outer six square set is equipped with external
Circle；The drag link sleeve is set in the periphery of long axis, and the left end of drag link sleeve is equipped with counterbore, and counter bore hole diameters size is more than circumscribed circle diameter
Size, counterbore depth dimensions are more than outer six sides location dimension, so that outer six side can sink in counterbore；In assembled state, pressure
It splits pump hydraulic end to be bonded with drag link sleeve right side, the distance between power end of fracturing pump and pressure break pump hydraulic end are by drag link sleeve
Overall dimensions ensure.
Said program can advanced optimize for：
There are slot holes at long axis inside the drag link sleeve, to realize the clearance fit of drag link sleeve and long axis.
A positioning surface is equipped on the outside of the positioning table, positioning surface is close to power end of fracturing pump in assembled state.
The pull rod shaft material uses stainless steel.
The utility model keeps pull rod overall stiffness more preferable by using fabricated structure, and fatigue life is improved, just
Existing phenomenon of rupture is often can not produce, processing is easier, versatile, and onsite application effect is fine.

Specific implementation mode
To make those skilled in the art more fully understand the utility model, below in conjunction with the accompanying drawings with embodiment to technical solution
It is described in further detail.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4.A kind of combined type pressure break pump rod, including pull rod shaft 1 and drag link sleeve 2.Pull rod shaft 1
Including power end connection screw thread 1.1, positioning table 1.2, outer six side 1.3, long axis 1.4, fluid end connection screw thread 1.5；Power end connects
Connect screw thread 1.1, fluid end connection screw thread 1.5 is located at the both ends of pull rod shaft 1；Positioning table 1.2 is close to power end connection screw thread
1.1；Outer six side 1.3 is set between positioning table 1.2 and long axis 1.4；Outer six side 1.3 is set with circumscribed circle 1.6.Outside positioning table 1.2
Side is equipped with positioning surface 1.2.1 can be screwed into fracturing pump by outer six side 1.3 in assembled state by power end connection screw thread 1.1
Power end 3 makes positioning surface 1.2.1 be close to power end of fracturing pump 3.1 material of pull rod shaft uses stainless steel, to ensure it with excellent
