Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, the present embodiment is implemented under premised on technical solutions of the utility model, should understand these embodiments and only be not used in restriction scope of the present utility model for illustration of the utility model.
As shown in Figure 1, the anti-tripping fastening devices of a kind of hydraulic sucker rod, comprise buffer and clamping device, described buffer is provided with spherical cavity 1, outward open mouth 2, bulb 3, connecting rod 4, balance bunker 5, slide plate 6, seal groove 7, sealing ring 8, on Compress Spring 9, lower Compress Spring 10, spring location-plate 11, tie rod holes 12, liquid flow hole 13; Described clamping device is provided with upper linking rod 21, screwed hole 22, circular hole clipping 23, cylinder dop 24, threaded rod 25, interior hex slot 26, lower linking rod 27, threaded column 28, cotter way 29.
Spherical cavity 1 is positioned at the lower end position of upper linking rod 21, open the center, lower surface that mouth 2 is positioned at upper linking rod 21 outward, opening is inwardly communicated with spherical cavity 1, one end of connecting rod 4 is fixedly connected with bulb 3, the other end is fixedly connected with slide plate 6, in order to ensure that the bulb 3 of connecting rod 4 upper end can have certain rotation amplitude, the bundle mouth diameter opening mouth 2 is outward less than the diameter of spherical cavity 1, but is greater than again connecting rod 4 diameter.
Seal groove 7 is positioned at the centre of slide plate 6 cylinder, be connected with sealing ring 8, described tie rod holes 12 is positioned at the upper surface of balance bunker 5, be connected with connecting rod 4, because the slide plate 6 in balance bunker 5 needs to carry out moving up and down repeatedly, main rubbing surface concentrates on sealing ring 8, so the inner surface of balance bunker 5 needs to have higher machining accuracy grade, roughness controls below 1.6, reduces because the tool marks on surface destroy the possibility of sealing ring 8.
Liquid flow hole 13 is positioned at the upper and lower end face of balance bunker 5, symmetrical, spring location-plate 11 is positioned at the upper and lower end face of slide plate 6, be fixedly connected with, upper Compress Spring 9 is enclosed within connecting rod 4, be positioned at the upper end of slide plate 6 and balance bunker 5 inner chamber, lower Compress Spring 10 is positioned at the lower end of slide plate 6 and balance bunker 5 inner chamber, balance bunker 5 arranges the effect that liquid flow hole 13 mainly plays a hydraulic cushion, the effect of a mechanical damping is played during the arranging of Compress Spring, the buffering of two vertical variable forcees is set herein simultaneously, mainly because of vertical variable force repeatedly, frequently, main applying power.
Upper linking rod 21 relies on the spherical cavity 1 of lower end and connecting rod 4 to be flexibly connected, and screwed hole 22 is positioned at the upper end of upper linking rod 21, is connected with the threaded column of upper end sucker rod.
Circular hole clipping 23 is positioned at the flank centre position of screwed hole 22, cylinder dop 24 is placed in circular hole clipping 23, one end of threaded rod 25 is fixedly connected with cylinder dop 24, the end face center of the other end is provided with interior hex slot 26, described rotating threaded rod 25, controls cylinder dop 24 movable in circular hole clipping.
The upper end of lower linking rod 27 is fixedly connected with the lower surface of balance bunker 5, lower end is fixedly connected with threaded column 28, cotter way 29 is positioned at the centre position of threaded column 28, left and right Parallel Symmetric, advance when cylinder dop 24 rotates, be stuck in after in cotter way 29, again play the fixing effect of an anticreep at connection of thread, after screw thread grinds off, sucker rod can not come off easily.
Whole device does the undertaking of a power between sucker rod, and whole device alleviates the stressed polytropy in sucker rod screw thread place in two, thus alleviates the wearing and tearing at screw thread place, increases application life.
When sucker rod is at transition location downwards or upwards, inspiration lower end, liquid flow hole 13 upper end on balance bunker 5 extrudes or inspiration upper end, lower end extrudes liquid, give the buffering course of a sucker rod power, Compress Spring up and down simultaneously in balance bunker 5 gives a buffering effect equally, reduce sucker rod screw thread screw thread place axially stressed suddenly, screw thread is split, repeatedly comes off after wearing and tearing.
A spherical movable joint is set at connecting rod 4 place, make the radial up and down of sucker rod can swing by a small margin, when sucker rod due to vibrations, tube wall collision etc. cause radial variable force time, the spheroid of connecting rod 4 upper end conforms needs, can multidirectionally change, the power that should be applied on screw thread place and sucker rod is dissolved, and again ensures the fastness of screw thread, and greatly reduce sucker rod due to fracture probability during construction, reduce engineering and to lie the quantity of well.
