Abstract

A hook wedging type pipe cable clamp is a clamp used for fixing a cable and an oil pipe in the downhole operation of an electric submersible pump. The oil pipe clamping device comprises a clamping ring consisting of a circular clamping opening (1) and a groove-shaped clamping opening (2), wherein an oil pipe is clamped at the circular part in the ring, and a cable is clamped at the groove-shaped part. One side of the clamp holder is connected by a pin shaft (4) to form a hinge which can be opened and closed; the other side is provided with a hook and a long round hole to form an inner angle shape which can be self-locked. After the oil pipe and the cable are clamped, a wedge pin (5) is inserted to drive the wedge pin to a depth so as to adjust the clamping force. The center of the outer edge profile of the pipe cable clamp holder is offset from the center of the inner circle by a distance, so that the cable occupies a reasonable space and is protected. The outer edge of the holder is provided with an inclined guide righting block extending towards one end so as to facilitate the entering of a well.

Description

Gripper block for pipe and cable

The utility model is to be used for well operations under the electric submersible pump of oil field, a kind of novel clamp of clamping oil pipe and cable.

In the well operations, wherein an important procedure is the fixing of cable and oil pipe under the electric submersible pump.Conventional practice is cable to be tightened on oil pipe as clamp with stainless steel band.Because oil well is irregular, in directional well,, when removing electric pump, often, cause economic loss especially because of pushing and rubbing and damage cable because of the stainless steel clamp is not set up the function and the centralizing function at sleeve pipe and oil pipe center.The stainless steel clamp is again disposable running stores, increases lifting expenses.

Occur several cable cleats recently, and shown characteristics separately.The most outstanding advantage of the utility model is, convenient mounting and clamping, in the anchor clamps without liner, direct clamping, clamping force is big.Extend to draw tiltedly and be beneficial to into well.

The purpose of this utility model:

For the traditional handicraft that changes attached cable with overcome the problem of disposable consumption, design a kind of new anchor clamps, make it can protect cable, can make simple in structurely, easy to operate, durable in use again, obtain the substituting product that function and benefit are unified.Therefore, designed the utility model.

Particular content of the present utility model is:

Hook wedging type pipe cable clamper mainly constitutes a clamp ring by circle folder mouthful (1) and flute profile folder mouthful (2), with clamping oil pipe and cable.One side of ring connects with bearing pin (4), forms hinge, can free folding.The opposite side that encircles is made the hook of band gradient on circle folder mouth, be shaped on slotted hole on the flute profile folder mouth, and two form an interior angle with self-locking performance altogether, insert taper (5), locks with taper adjustment chucking power and with clamp ring.In the ring of clamper, circular position and oil pipe coupling, flute profile position clamping cable, and be lined with interchangeable liner (3), to adapt to the different size cable.Make on the outer rim of clamper and draw oblique wiper block, be beneficial to go into the well and the friction of minimizing and sleeve pipe.

Characteristics of the present utility model:

The characteristics of hook wedging type pipe cable clamper, the one, main clamping action is created between folder mouthful and the oil pipe, and cable only is subjected to preventing the clamping force become flexible in the middle of oil pipe and clamper, thereby can not destroy the physical property of cable.Next is a clamper with oil pipe center and distance of cover tube hub tuningout, makes cable occupy suitable locus, when removing electric pump and oil pipe, has only contacting of clamper and sleeve pipe, protects effectively that cable is not squeezed, friction and scratching.It three is that the oblique wiper block of making on the clamper outer rim that draws stretches out to an end, is not blocked by well head when going into well with the guiding clamper.Other characteristics are to make clamp with the wedging mode, reliable lock.Clamper with after do not damage any part, reusable.

Fig. 1 is the front view of hook wedging type pipe cable clamper;

Fig. 2 is the vertical view and the broken section of hook wedging type pipe cable clamper.

Introduce specific embodiment of the utility model with reference to the accompanying drawings:

As shown in the figure, the circle folder mouthful (1) and the flute profile folder mouthful (2) of hook wedging type pipe cable clamper all are to make with metal.Be lined with interchangeable liner (3) in the groove of flute profile folder mouth, to adapt to the cable of different size.During use, open clamper along hinge pin (4), with pack into flute profile folder mouthful of cable, be buckled on the oil pipe by giving the position of reserving, the garden clevis mouth that closes again gives tightly with special vice earlier, inserts taper (5) wedging that pounds with a hammer again, and soon oil pipe and cable are clamped.Taper is locking by self-locking performance.When clamper is gone into well, draw a end that oblique wiper block stretches out down.

Claims

1, hook wedging type pipe cable clamper, form a clamp ring by a circle and a flute profile folder mouth, a side that it is characterized in that circular folder mouth (1) and flute profile folder mouthful (2) connects the formation hinge with bearing pin (4), can free folding, opposite side is shaped on hook and slotted hole, composition one has the interior angle of self-locking performance, inserts taper (5) wedging.

2, hook wedging type pipe cable clamper as claimed in claim 1 is characterized in that with outer margin contour center and distance of internal diameter center tuningout, as the position of cable.

3, hook wedging type pipe cable clamper as claimed in claim 1 is characterized in that two oblique wiper blocks that draw that draw oblique wiper block and flute profile folder mouthful flute profile position on the clevis mouth outer rim of garden extend to an end.
