Abstract
The utility model relates to a screw head fixed device of a reduction box of an oil pumping machine. The screw head fixed device of the reduction box of the oil pumping machine comprises a multi-ridge sleeve head, a U-shaped seat, an ejector wire and an adjusting rod, wherein the adjusting rod is in threaded connection with the U-shaped seat, the adjusting rod penetrates through the U-shaped bottom of the U-shaped seat and is connected with the multi-ridge sleeve head, and the multi-ridge sleeve head is arranged in the U-shaped seat. The ejector wire is in threaded connection with the outer side of the U-shaped bottom of the U-shaped seat, and the maximum diameter of the horizontal direction of the multi-ridge sleeve head is larger than the diameter of the inner side of the U-shaped seat. The screw head fixed device of the reduction box of the oil pumping machine has the advantages of being simple in structure and convenient to install, achieving safe and rapid disassembly and assembly of a screw, reducing well-remaining time, improving oil production rate, simultaneously reducing damage rate of the screw, reducing cost consumption, and reducing labor intensity of workers.
Description
Technical field
The utility model relates to the screw fixture, particularly a kind of fixture for the oil pumping unit reduction gearbox screw terminal.
Background technology
The pumping well ground management is oil recovery worker's an important daily management mission.In the normal production of rod-pumped well, because the factors such as formation oil is thick, sand card can make pumping unit load increase, often cause occurring some loosened screws, cause great potential safety hazard.For guaranteeing the safe and efficient running of oil pumper, need regularly each position screw of oil pumper to be carried out fastening adjustment work.Because the position narrow space such as reduction box, personnel's difficulty that cooperatively interacts is large, does not use strength, and to use the instrument that is fit to according to the screw size, the easy slippage of the instrument personnel that cause such as use spanner injure, and because the space is little, make easily the screw discontinuity, when operating, easily cause the screw slide fastener, the dismantling screw of having to is changed again, and it is long to cause stopping the well time, rate when having a strong impact on the oil recovery of oil well also increases operating personnel's operational danger.Especially in winter, also cause easily the high wax containing well blocking pipeline because holding screw stops the well overlong time, increase operating personnel's workload.
The utility model content
For the defective that exists in the prior art, the purpose of this utility model is to provide and can adapts to small space, reduces the oil pumping unit reduction gearbox screw terminal fixture of worker's labour intensity.
For reaching above purpose, the technical scheme that the utility model is taked is:
A kind of oil pumping unit reduction gearbox screw terminal fixture, comprise pullover, the U-shaped seat of many ribs, jackscrew and adjusting rod, described adjusting rod is threaded with U-shaped seat, the U-shaped bottom that described adjusting rod passes U-shaped seat is connected with many ribs are pullover, described many ribs are pullover to be placed in the U-shaped seat, described jackscrew is threaded at U-shaped bottom outside place with U-shaped seat, and the pullover horizontal direction maximum gauge of described many ribs is greater than the inboard footpath of described U-shaped seat.
On the basis of such scheme, described many ribs are pullover to be that six ribs are pullover.
The beneficial effects of the utility model: simple in structure, easy for installation, realize safety, quick demolition, installation screw, reduce and stop the well time, improve rate when recovering the oil, reduce simultaneously the screw spoilage, Cost reduction consumption reduces worker's labour intensity.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, a kind of oil pumping unit reduction gearbox screw terminal fixture, comprise pullover 1, the U-shaped seat 2 of many ribs, jackscrew 3 and adjusting rod 4, described adjusting rod 3 is threaded with U-shaped seat 2, the U-shaped bottom that described adjusting rod 4 passes U-shaped seat 2 is connected with many ribs pullover 1, described many ribs pullover 1 are placed in the U-shaped seat 2, and described jackscrew 3 is threaded at U-shaped bottom outside place with U-shaped 2, and the horizontal direction maximum gauge of described many ribs pullover 1 is greater than the inboard footpath of described U-shaped seat 2.
Preferably, described many ribs pullover 1 are that six ribs are pullover.
During use, with pullover 1 card of many ribs of oil pumping unit reduction gearbox screw terminal fixture with on the screw terminal of needs dismounting, by regulating jackscrew 3, oil pumping unit reduction gearbox screw terminal fixture is fixed.
With the nut of the nut spanner set screw other end, can be with screw dismounting.
This oil pumping unit reduction gearbox screw terminal fixture, in use have save time, laborsaving, safety, not only greatly reduce operating personnel's labour intensity, raise labour efficiency, also improved safety coefficient simultaneously.
