Abstract
The utility model provides an auxiliary dismounting tool for a rotary-guide hydraulic pump, which mainly comprises a pump body, a housing, an outer cylinder, a pin, a sealing ring, screws, a cover plate, a pressing plate, a lead screw and a rotating spanner, wherein the pressing plate is fixed at the bottom end of the lead screw by the screws; the pressing plate with the diameter thereof being smaller than the internal diameter of the housing is supported on the pump body of the hydraulic pump; two circular holes are symmetrically formed on the outer cylinder of the auxiliary dismounting tool; small screws are fixed on the screw holes of the outer housing of the hydraulic pump via the circular holes, and the distance between the internal diameter of the outer cylinder and the external diameter of the housing is small, thereby ensuring the close fit and preventing the pump body from being damaged by the outer cylinder and the housing which get loosened in the vertical direction in the dismounting process; and the length of the lead screw is larger than that of the outer housing of the hydraulic pump, thereby ensuring that the lead screw has enough distance for dismounting the housing through axial movement. Based on the design applying the lead-screw principle to stress conversion, an operator can easily achieve the axial movement of a cylinder sleeve by rotating a spanner, therefore, the utility model reduces the labor intensity, protects the pump body of the hydraulic pump, saves the operating time and is particularly suitable for on-field application.
Description
The utility model relates to a kind of oil, supporting extracting tool of gas drilling rotary steering technical field hydraulic pump of being used for.
Background technology
Since the eighties in 20th century, each oil field enters development late stage in succession in the world, old filed is for realizing stable yields, be faced with the development problem of difficult mining-employed reserveses such as a large amount of edge oil-gas reservoir, independent little oil-gas reservoir, complex fault block oil-gas reservoir, ultra-thin oil-gas reservoir, the oil reservoir development difficulty increases gradually, factors such as oil reservoir development situation, geology reservoir are more and more harsher to the requirement of drilling well, and various factors forces domestic drilling technology to develop to automation direction as early as possible.Rotational automatic guiding closed loop drilling technology is a most advanced and sophisticated automated drilling new technology of the multinational major company in world today competition development, and it represents one of world today's drilling technology development highest level, and this technology will make the world's drilling technology qualitative leap occur.Hydraulic pump in the rotary steerable tool is positioned at tool lower portion, in rotary steerable tool hydraulic pump unloading process, at first needs the housing of hydraulic pump is removed, and could remove inner body afterwards.Outer casing closely contacts with the pump housing, and the outer cylinder sleeve of hydraulic pump is relatively thin, is not damaged when being used for protecting pump housing work; need the special protection pump housing in the unloading process; this brings very big difficulty to dismounting, and wastes time in the unloading process at the scene, increases labour intensity.
The utility model content
For overcoming long, difficulty such as labour intensity is big of casing of hydraulic pump take-down time; utilize the utility model can be in dismounting outer casing process; the accurate protection pump housing is not damaged, and easily realizes the close installation of the outer casing and the pump housing, and convenient the fixing of the two of carrying out.The purpose of this utility model is exactly the kit that dismounting for the hydraulic pump outer casing provides a kind of quick and easy, easy realization.
The utility model design that is adopted of dealing with problems is: the supporting extracting tool of this rotary steering hydraulic pump, mainly form by the pump housing, housing, urceolus, pin, sealing ring, screw, cover plate, pressing plate, leading screw, rotary spanner ten parts.Pressing plate is fixed on the leading screw bottom by screw, and pressing plate is supported on the hydraulic pump body, and its diameter is less than the housing internal diameter.Kit urceolus symmetry has two circular holes, and primary screw is fixed on the screw hole of hydraulic pump outer casing by circular hole, and urceolus internal diameter and housing external diameter are less at interval, guarantees to cooperate closely, can the up and down damage pump housing during dismounting.Leading screw length guarantees that greater than hydraulic pump outer casing length leading screw moves axially the dismounting housing enough distances are arranged.
The utility model has the advantages that; when the rotary steering hydraulic pump is dismantled; use the leading screw principle and carry out stressed conversion; operating personnel have easily realized moving axially of cylinder sleeve by the rotation of spanner; reduced labour intensity; protect hydraulic pump body during dismounting, saved the working time, be particularly suitable for The field.
Description of drawings
The supporting extracting tool schematic diagram of a kind of rotary steering hydraulic pump of Fig. 1.
Among the figure: 1 pump housing, 2 housings, 3 urceolus, 4 pins, 5 sealing rings, 6 screws, 7 cover plates, 8 pressing plates, 9 leading screws, 10 rotary spanners
The specific embodiment
According to Fig. 1 the utility model is further described below.
Referring to Fig. 1, the supporting extracting tool of a kind of rotary steering hydraulic pump mainly is made up of the pump housing 1, housing 2, urceolus 3, pin 4, sealing ring 5, screw 6, cover plate 7, pressing plate 8, leading screw 9, rotary spanner 100 parts.During use, at first allow leading screw 9 rotations by pressing plate 8, then cover plate 7 usefulness screws 6 are fixed on the leading screw 9, the urceolus 3 of supporting extracting tool is enclosed within on the casing of hydraulic pump 2, make the pin-and-hole alignment on the two circumference, connect by pin, the rotary spanner 10 that turns clockwise is pressed on the pump housing 1 cover plate 7, be rotated further rotary spanner 10, central role power acts on the pump housing 1 by cover plate 7, the continuation of leading screw 9 is moved and is realized that urceolus 3 and the outside of housing 2 move, thereby has realized relatively moving of the housing 2 and the pump housing 1, reaches the purpose of dismounting housing 2.
The utility model carries out stressed conversion because the screw mandrel principle is used in design; operating personnel have easily realized moving axially of housing by the rotation of spanner; greatly reduce labor intensity of operating personnel; thereby the stressed evenly protection pump housing of housing was not damaged when dismantling; saved the time of repetition test; this instrument is light reliable, is convenient for carrying, and is particularly suitable for The field.
