Description
Technical field
The present invention relates to oil pumper, more particularly to a kind of portable balance oil extractor for coal bed gas extraction.
Background technology
Coal bed gas is commonly called as gas, is universally acknowledged eco-friendly power source as Unconventional gas.China's coal bed gas resource ten
It is point abundant, influenceed by " three low one is high " (i.e. low pressure, low saturation, low-permeability and air content high), China's coal bed gas is opened
Adopt difficulty very big.
Due to Production of Coal-bed Gas Wells change greatly, selected apparatus and method should ensure gas storage stressor layer in a short time
It is down to below desorption pressures, makes gas-bearing reservoir aerogenesis as early as possible；Ensure balanced step-down again, prevent coal seam particle migration, destroy gas storage
Layer, influences gas production.In the prior art, the ground acquisition of coal bed gas is generally carried out using oil pumper.
Conventional 3-5 type oil pumpers, when polished rod load changes needs adjustment, it is necessary to balance fastening after shutdown
The bolt of block is unloaded down, is hung on crane, hung down or mobile balanced block, particularly to the frequent periodicity of coal bed gas well polished rod load
Change is big, need to frequently adjust the situation of balance, and it is very inconvenient that adjustment is got up, and takes a lot of work, time-consuming and laborious, for bad environments
Remote districts are more inconvenient.
Based on this, prior art is needed to be improved really.
The content of the invention
The present invention need to provide a kind of oil pumper, to solve problems of the prior art.
In order to solve the above-mentioned technical problem, the invention provides a kind of portable balanced type oil pumping for coal bed gas extraction
Machine, the technical scheme that it is used is as follows：
The shifting balance formula oil pumper for coal bed gas extraction, including base, support, walking beam, horse head, crossbeam branch
Seat, linkage, decelerator, motor, bascule, arm body and bottom bracket bearing seat, support be arranged on base on, decelerator and
Motor is fixed in the specialized agency of base, and walking beam is connected to cradle top by bottom bracket bearing seat, and walking beam is around bottom bracket bearing
Seat swings, and described horse head hangs over walking beam head by the center of circle of axis, and the horse head for hanging over walking beam head does by the center of circle of axis
Circular motion, so as to drive air exhaust rod to move up and down, realizes the purpose of extraction.Linkage upper end is by beam support and trip
Beam rear part is connected, and linkage lower end is connected with the output shaft of decelerator, decelerator and motor connection, and arm body is suspended on walking beam
Tail end, arm body is provided with bascule.Safe walkway is safety devices when overhauling walking beam, guarantor when maintenance platform is maintenance
Protection unit, safe case is the protection device of belt transmission, and centralized lubrication device is the device of each position centralized lubrication of whole machine.
Further, bascule is the rack and pinion drive with self-locking device, and bascule is engaged by gear
On arm body, bascule is driven by independent motor.During adjustment, the device can stop in any position, will not
It is mobile.
Further, horse head is formed by steel plate and the weldering of shaped steel group, and is lateral rotating type structure.
The present invention compared with prior art, has the advantages that：
1) balance mode that curved walking beam allocates loaded van is employed, the just easy many of balancing.Adjust stroke convenient, equipped with spiral shell
Bar self-locking device, can fix the walking beam of activity with support without unloading, and maximum stroke can reach 1500mm.
2) decelerator output torque and output power of motor are reduced, the stress of the parts such as crossbeam, crank-pin is improved
Situation, improves the reliability and durability of air exhauster.
3) suspension point carry does not need crane less important work after well workover.Operational maintenance is essentially identical with conventional machine, due to electronic
The torque ratio same specification routine machine that machine, decelerator are transmitted is small, and consumable accessory, tumbler are than conventional machine long lifespan.Air exhauster adjustment ginseng
Number is easy.
Brief description of the drawings
Fig. 1 is the structural representation of one embodiment of the invention；
Wherein, 1- horse heads, 2- walking beams, 3- arm bodies, 4- decelerators, 5- linkages, 6- motors, the safe cases of 7-, 8-

Specific embodiment
To make the technical problem to be solved in the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and tool
Body embodiment is described in detail.
As shown in figure 1, a kind of shifting balance formula oil pumper for coal bed gas extraction, including base 8, support 9, walking beam 2,
Horse head 1, beam support 11, linkage 5, decelerator 4, motor 6, bascule 10, arm body 3 and bottom bracket bearing seat 15, branch
Frame 9 is arranged on base 8, and decelerator 4 and motor 6 are fixed in the specialized agency of base 8, and walking beam 2 is by bottom bracket bearing seat 15
The top of support 9 is connected to, walking beam 2 swings around bottom bracket bearing seat 15, and described horse head 1 hangs over walking beam 2 by the center of circle of axis
Head, the horse head 1 for hanging over walking beam head does circular motion by the center of circle of axis, so as to drive air exhaust rod to move up and down, realizes
The purpose of extraction.The upper end of linkage 5 is connected by beam support 11 with the afterbody of walking beam 2, the lower end of linkage 5 and decelerator 4
