Abstract

The utility model discloses a special lathe-dog assembly for well cleanout, which comprises an upper lathe-dog piece taking the shape of a semicircle, a lower lathe-dog piece taking the shape of the semicircle, a I-typed shaft pin and a T-typed threaded bolt. Left clamping blocks are arranged at the left ends of the upper lathe-dog piece and the lower lathe-dog piece, and right clamping blocks are arranged at the right ends thereof; U-shaped holes are formed at the middle parts of the left clamping blocks and the right clamping blocks; a group of right shaft pin seats are respectively arranged at the rear ends of the two groups of the right clamping blocks; the two ends of the I-typed shaft pin are inserted into the two groups of the right shaft pin seats; a group of left shaft pin seats are arranged at the rear ends of the left clamping blocks on the upper lathe-dog piece; and one end of the T-typed threaded bolt is inserted in the left shaft pin seats, and a nut is arranged at the other end thereof. The special lathe-dog assembly obtains the beneficial effects as follows: (1) the structure is simple and the carrying is easy; and (2) when fastening a lathe-dog, the threaded bolt and the nut need to be tightened only, so the manpower is saved, the operating time is reduced, and the working efficiency is increased.

Description

Well-flushing clamp special assembly

Technical field

The utility model relates to a kind of clip assembly, particularly a kind of well-flushing clamp special assembly.

Background technology

It is an extremely important and regular job that oil field oil recovery unit carries out well-flushing to producing well, particularly heavy oil wells, paraffin-troubled well, sand output well, often regularly well-flushing can improve pump efficiency, reduces the oil pumper load, reduce frictional resistance, cleaning deep well pump travelling valve seat and the standing valve seat of oil pumping rod tube, thereby improves well yield.

In the washing well process, it is exactly the water under high pressure tengential belt of high pressure pump truck to be connected link together with the well head sleeve gate that an essential job is arranged, connecting portion be two clip head rests together, a ring gasket is put in the centre, be stuck on the clip head that ring gasket is housed with biplate four hole clip sheets again, two screw rods are through respectively in the clip eyelet, last jack panel plays fixed effect, at present, in practical operation, above-mentioned steps need be finished in double harness, one people accomplishes fluently back-up tong, another human spanner firmly tightens, and hocketing up to tightening in both sides, relatively wastes time and energy.

Summary of the invention

Problem to be solved in the utility model is: a kind of well-flushing clamp special assembly of saving manpower, reducing the operating time and can increase work efficiency is provided.

In order to solve the problems of the technologies described above, well-flushing clamp special assembly of the present utility model, comprise the semicircular hoop sheet of going up, the semicircular sheet of hoop down, worker's profile shaft pin and T type bolt, the described left end of going up hoop sheet and following hoop sheet is equipped with a left clamp, right-hand member is equipped with a right clamp, the centre of left side clamp and right clamp all has the U-shaped hole, the rear end of described two groups of right clamps respectively is provided with one group of right pivot pin seat, the two ends of described worker's profile shaft pin are inserted in two groups of right pivot pin seats, described rear end of going up the left clamp of hoop sheet is provided with one group of left side pivot pin seat, one end of described T type bolt is inserted in the left pivot pin seat, and an other end is provided with a nut.

Well-flushing clamp special assembly of the present utility model, described going up in the inner chamber that binds round sheet and bind round sheet down is equipped with inner card cage.

The beneficial effect that the utility model is obtained is: (1) simple in structure, be easy to carry about with one.(2) during fastening clip, only a bolt and nut need be tightened and get final product, so save manpower, reduce the operating time, improve operating efficiency.

The specific embodiment

Extremely shown in Figure 5 as Fig. 1, well-flushing clamp special assembly of the present utility model, comprise the semicircular hoop sheet 4 of going up, the semicircular sheet 9 of hoop down, worker's profile shaft pin 7 and T type bolt 2, the described left end of going up hoop sheet 4 and following hoop sheet 9 is equipped with a left clamp 10, right-hand member is equipped with a right clamp 8, the centre of left side clamp 10 and right clamp 8 all has U-shaped hole 11, the rear end of described two groups of right clamps 8 respectively is provided with one group of right pivot pin seat 6, the two ends of described worker's profile shaft pin 7 are inserted in two groups of right pivot pin seats 6, described rear end of going up the left clamp 10 of hoop sheet 4 is provided with one group of left side pivot pin seat 3, one end of described T type bolt 2 is inserted in the left pivot pin seat 3, an other end is provided with a nut 1, and described going up in the inner chamber that binds round sheet 4 and bind round sheet 9 down is equipped with inner card cage 5.

During concrete operations, hoop sheet 4 and following hoop sheet 9 block water under high pressure tengential belt and well head sleeve gate in the rotation, then T type bolt 2 are passed down the U-shaped hole 11 of the left clamp of hoop sheet 9, and last jack panel 1 gets final product.The whole operation process only need tighten a nut 1, therefore, has therefore saved manpower, has reduced the operating time, has improved operating efficiency.
