Interior to be provided with arc anchor fluke, the outer surface of anchor fluke is curved surface, and consistent with the curvature of curved surface of body；The inner surface of anchor fluke is provided with spacing
Plate, spacing plate shape is consistent with the groove shapes on body, and is located at same cambered surface, is formed in limiting plate and body recess surface
Cavity inner support have back-moving spring；Be provided with sand-proof pipe in the inner surface of limiting plate, the both ends of sand-proof pipe respectively with top connection and
The spacing contact in end face of lower contact；The wide feed liquor seams of several 0.1~0.19mm are offered on sand-proof pipe.
Described limiting plate and the contact surface of sand-proof pipe are provided with vulcanised rubber layer.
Described groove is strip hole or arc hole shape.
Described limiting plate is provided with spring base hole, and back-moving spring one end is landed in spring base hole, and the other end is supported on
On body recess bottom surface.
The hydraulic anchor sets the anchor fluke with back-moving spring by setting groove in body in groove, outside anchor fluke
Portion set sand-proof pipe carry out it is spacing, so as to ensure that anchor fluke sand-proof pipe with groove cavity according to pressure it is different realize anchor and
The function of deblocking.
The contact surface of limiting plate and sand-proof pipe is provided with vulcanised rubber layer, for sealing the limiting plate of anchor fluke, makes limiting plate
Produce piston effect.
Groove is strip hole or arc hole shape, and strip hole is easy to process, easy for installation；Arcuate socket processing difficulties, still
The corresponding lifting surface area for adding limiting plate, the pressure born is bigger, and stability is more preferable.
Limiting plate is provided with spring base hole, spacing to back-moving spring progress, further ensures the stability of work.

Embodiment
Embodiment one
As shown in Figures 1 to 5, a kind of hydraulic anchor, top connection 1 and lower contact 2 are tightly connected respectively at the both ends of body 4,
The both ends of top connection 1 and lower contact 2 are connected with external equipment respectively, and top connection 3 sets internal thread, and lower contact 2 sets external screw thread；
In the inner periphery of body 4, the groove of three strip hole shapes of circumference uniform distribution, as shown in Figure 2；The depth of groove is less than body 4
Wall thickness, two round tube holes 11 are offered in groove, be provided with arc anchor fluke 3 in each round tube hole 11, the outer surface of anchor fluke 3 is
Curved surface, and it is consistent with the curvature of curved surface of body 4；The inner surface of two anchor flukes 3 connects limiting plate 5 jointly, spacing in the present embodiment
Plate is structure as a whole with anchor fluke；The shape of limiting plate 5 is consistent with the groove shapes on body, and is located at same cambered surface, in limiting plate 5
The cavity inner support formed with the groove surfaces of body 4 has back-moving spring 6, in the both ends of limiting plate 5 and the centre of two anchor flukes 3 point
Not She You spring base hole 9, the one end of back-moving spring 6 is landed in spring base hole 9, and the other end is supported on body recess bottom surface；
The inner surface of limiting plate 5 is provided with sand-proof pipe 7, the both ends of sand-proof pipe 7 respectively with the end face of top connection 1 and lower contact 2 is spacing contacts；
The wide feed liquor seams 8 of several 0.1~0.19mm are offered on sand-proof pipe 7, when being filled with highly pressurised liquid in body 4, you can pass through
The promotion limiting plate of feed liquor seam 8 and anchor fluke are displaced outwardly, and so as to play a part of anchoring, while the grains of sand thing in sand-proof pipe 7 is hindered
Gear.
As shown in figure 5, the contact surface of described limiting plate 5 and sand-proof pipe 7 is provided with vulcanised rubber layer 10, for sealing anchor
The limiting plate of pawl, limiting plate is set to produce piston effect.
Embodiment two
As shown in Figure 6 to 8, except opening up the groove of circumference uniform distribution on body, while phase is also opened up in the axial direction
With the groove of group, a limiting plate 5 is threadedly coupled an anchor fluke 3, and limiting plate is easy to process with anchor fluke Split type structure, and limiting plate
Arcuate structure is employed, corresponding body recess structure is also miniature consistent with limiting plate 5, plays spacing plate suqare increase,
Pressure area is improved, therefore improves anchoring effect.Remaining structure is identical with embodiment one.
Embodiment three
Three anchor flukes 3 are set on a limiting plate 5 as shown in figure 9, removing, remaining structure is identical with embodiment one.
In summary, the body 4 of appropriate length, while the anchor fluke number set in body 4 can be selected according to need of work
Amount, can be set according to the length of body, also can using embodiment one into embodiment three any two kinds of combination settings.
The course of work of hydraulic anchor is：After instrument is with process pipe string tripping in precalculated position, pressurizeed in oil pipe body 4, by
Hydraulic drive, the caulking gum deformation of the bottom periphery of anchor fluke 8, produces piston effect with body, promotes anchor fluke 3 to expand outwardly, directly
Extremely it is bonded completely with the borehole wall；After the completion of construction, oily overpressure emptying, promote the hydraulic thrust power of anchor fluke to disappear, resetting
Under the promotion of spring 6, anchor fluke 3 is bounced back to tool interior until being bonded with sand-proof pipe 7, completion anchor fluke retraction.
The hydraulic anchor of the application uses brand-new design, has abandoned waterpower anchor lining this structure design, and anchor fluke piston uses
Elliptic structure, anti-rotation, the righting area of anchor fluke are effectively increased while anchor fluke piston effect is ensured, it is ensured that anchor fluke is lived
Fill in the free walker of motion；Simultaneously by back-moving spring installation diagram body, the installation site of spring and the work of spring is effectively ensured
Condition.
The present invention not only solves righting, anti-rotation and the telescopicing performance of hydraulic anchor anchor fluke, meanwhile, by the piston of anchor fluke bottom
Area increases to more than 3 times of original design, considerably increases hydraulic anchor anchor fluke caused anchorage force under the effect of equal pressure,
Further enhancing the anchoring ability of hydraulic anchor, for safely, smoothly complete the job executions such as underground fracture, acidifying and provide more
Complete protection.
