Description
Technical field
The present invention relates to a kind of oil field and use oil pumper, be specifically related to a kind of underlying rolling wheel formula oil pumper.
Background technology
Mostly China oil field is low energy, the stripper field of hyposmosis; Changing oil or change oil with water with electricity is the production status in China oil field, and the electricity charge have accounted for sizable ratio in the China's oil cost of winning, according to statistics; Electricity charge expenditure in the average crude oil cost per ton accounts for 20～30%; Electricity charge expenditure in the local field produces cost is bigger, so petroleum industry is attached great importance to saves energy.Because domestic oil pumper seldom has big innovation at frame for movement and control system aspects, the operational efficiency of oil pumper is low especially.At present, domesticly some energy-saving beam pumping units occur, but do not brought into play energy-saving potential to greatest extent generally.
Chinese patent " ZL 200620136374.7 " and " 200920274845.4 " disclose " the synchronous draw twin-well oil-pumping machine of rare earth permanent magnet gearless " and " a kind of twin-well column oil rig "; The traction machine cost that uses in two patented products is higher; And be not easy to change, come very big inconvenience for the work zone, oil field, and when a bite well servicing; Another mouthful well can't operate as normal, does not reach the instructions for use in oil field.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of underlying rolling wheel formula oil pumper, satisfied the maintenance requirement and the instructions for use in oil field, and have simple in structure, low cost of manufacture, stable advantage.
In order to achieve the above object, the technical scheme taked of the present invention is following:
A kind of underlying rolling wheel formula oil pumper comprises base 1, and transmission base 21 is installed on the base 1 with link 15; Switched reluctance machines 20, brake 19 and deceleration device 18 are installed on the transmission base 21, and shaft coupling 17 is installed on the deceleration device 18, and 2# power transmission shaft 12 is installed on the base 1; Reel 13 is installed on the base 1 through 2# power transmission shaft 12, and is connected with shaft coupling 17 through 2# power transmission shaft 12, and supplemental support 16 is connected with link 15 with base 1 through connecting axle 22; Top rail 14 is installed on the link 15; Two wobble wheel 7 symmetries are installed in the both sides of the last installed surface of top rail 14, and 1# power transmission shaft 8 is installed on the wobble wheel 7, and two deflecting roller 9 symmetries are installed in the both sides of the last installed surface of top rail 14; Two little deflecting roller 10 symmetries are installed in the both sides of the interior installed surface of top rail 14; Two guiding device 3 symmetries are installed in the both sides of lower bottom base 1 and top rail 14, and two counterweight assemblies 2 are installed in respectively in two guiding devices 3, and belt assembly 6 is fixed on the reel 13; Polished rod eye assembly 5 is fixed on the belt assembly 6, and sucker rod 4 is fixed on the polished rod eye assembly 5 through side's card 11.
Described wobble wheel 7 can rotate around 1# power transmission shaft 8.
The present invention has the following advantages:
Because particular design of the present invention, so another mouthful well still can operate as normal during the individual well maintenance.The present invention is simple in structure, and is stable, is convenient to install, and is convenient to safeguard.
Description of drawings
Fig. 1 is a contour structures sketch map of the present invention.
Fig. 2 removes the lateral view behind the counterweight assembly of both sides for the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done detailed description.
See figures.1.and.2, a kind of underlying rolling wheel formula oil pumper comprises base 1; Transmission base 21 is installed on the base 1 with link 15, and switched reluctance machines 20, brake 19 and deceleration device 18 are installed on the transmission base 21, and shaft coupling 17 is installed on the deceleration device 18; 2# power transmission shaft 12 is installed on the base 1, and reel 13 is installed on the base 1 through 2# power transmission shaft 12, and is connected with shaft coupling 17 through 2# power transmission shaft 12; Supplemental support 16 is connected with link 15 with base 1 through connecting axle 22, and top rail 14 is installed on the link 15, and two wobble wheel 7 symmetries are installed in the both sides of the last installed surface of top rail 14; 1# power transmission shaft 8 is installed on the wobble wheel 7; Two deflecting roller 9 symmetries are installed in the both sides of the last installed surface of top rail 14, and two little deflecting roller 10 symmetries are installed in the both sides of the interior installed surface of top rail 14, and two guiding device 3 symmetries are installed in the both sides of lower bottom base 1 and top rail 14; Two counterweight assemblies 2 are installed in respectively in two guiding devices 3; Belt assembly 6 is fixed on the reel 13, and polished rod eye assembly 5 is fixed on the belt assembly 6, and sucker rod 4 is fixed on the polished rod eye assembly 5 through side's card 11.
