Abstract
The present invention relates to a kind of oil pumper of high service life, the oil pumper processes double spiral groove in head sheave, two steel wire ropes linked together are provided with the double spiral groove, pass through the design of double spiral groove, it can be very good to reduce day wheel diameter, rope service-life is improved, so as to add the service life of oil pumper as transmission mechanism by the way of two steel wire ropes link together simultaneously.
Description
Technical field
The present invention relates to vertical oil-pumping machine field, specially a kind of oil pumper of high service life.
Background technology
Because present oil field requires that oil pumper need to meet sving long-stroke-distance low-stroke time requirement, stroke will meet more than 8 meters, head sheave external diameter
2500 need to be reached, therefore larger wheel footpath causes steel wire rope to install, replacing is difficult to operate, and larger head sheave increases on pylon
Added the danger of equipment, thus domestic manufacturer's head sheave diameter 1700 or so, the requirement of small stroke well, nothing can only be met
Method meets the requirement of existing oil field long stroke；Meanwhile, steel wire rope is used to be single, in use, due to the power born very
Greatly, the fracture of steel wire rope is easily caused, life requirements of the oil field on steel wire rope is can not meet.
The content of the invention
It is an object of the invention to provide a kind of oil pumper of high service life, the oil pumper designs a kind of new steel wire
Rope layout, to improve service life of steel wire rope, while under the premise of oil field stroke requirement is met, also reducing a day wheel diameter.
To achieve the above object, the present invention provides following technical scheme：A kind of oil pumper of high service life, takes out described
Processed in the head sheave of oil machine and two steel wire ropes linked together are provided with double spiral groove, the double spiral groove.
Further, the double spiral groove pitch is between 24mm-40mm.
Further, the steel wire rope is fixed in head sheave using pressing plate.
Further, in addition to a wire rope casing, for two steel wire ropes described in nesting, so that two steel wires
Rope forms an entirety.
Further, two steel wire ropes are connected by the way of winding.
Further, rotatable attachment means are used between the steel wire rope and well head or configuration end.
The present invention compared with prior art, the beneficial effects of the invention are as follows：
1. using the design of double spiral groove in head sheave, reduce day wheel diameter；Because present oil field requires that oil pumper need to meet long stroke
Low jig frequency requirement, stroke will meet more than 8 meters, and head sheave external diameter need to reach 2500, and larger wheel footpath causes steel wire rope to install, change
It is difficult to operate, and larger head sheave adds the danger of equipment on pylon；Therefore the diameter of domestic manufacturer's head sheave exists
1700 or so, the requirement of small stroke well can only be met, it is impossible to meet the requirement of existing oil field long stroke；New double spiral groove is set
Meter, steel wire rope rotates 1.5 circles in head sheave can meet 8 meters of stroke requirements, greatly reduce the external diameter of head sheave.
2. rope service-life is improved, the Novel steel wire rope end connection of design so that oil pumping function uses 8,16 steel
Cord transmission is without using movable pulley structure so that the safety coefficient of steel wire rope improves n times times of 2, in same wheel footpath
In the case of, the structure rope service-life is than improving 4-8 times under regular situation, meeting oil field will on the life-span of steel wire rope
Ask.
3. steel wire rope and the connection of well head or Balance weight end, using rotatable attachment means, it is ensured that steel wire rope stress is equal
Even, than tradition, manually pretension reaches that steel wire rope uniform force is accurate, reliable.

Embodiment, belongs to the scope of protection of the invention.
Refer to shown in Fig. 1-2, the present invention provides following technical scheme：A kind of oil pumper of high service life, described
Processed in the head sheave 1 of oil pumper in double spiral groove 2, the double spiral groove 2 and be provided with two steel wire ropes linked together 3, its
In, the pitch of double spiral groove 2 is between 24mm-40mm, and steel wire rope 3 is fixed in head sheave 1 using pressing plate, meanwhile, the steel
Rotatable attachment means are used between cord 3 and well head or configuration end.
Embodiment one：
As described in Figure 3, in the present embodiment, two steel wire ropes 3 are connected by the way of winding, so that two steel wire ropes 3
Form an entirety.
Embodiment two：
As shown in figure 4, in the present embodiment, in addition to a wire rope casing 6, for two steel wire ropes 3 described in nesting, so that
Two steel wire ropes 3 formation, one entirety.
In the present embodiment, the mode that described two steel wire ropes 3 can be set up in parallel or wind is connected.
In the present embodiment, steel wire rope 3 is not bent nesting and entered by the molten steel rope sleeve 6, but two ends are respectively stayed
10cm-50cm steel wire rope comes out.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of changes, modification can be carried out to these embodiments, replace without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
