Abstract

A rope hoist supporting bracket used for pump well hanging device includes an upper retaining ring, a lower retaining ring, an upright plate, a baffle, a fixing bolt, a cross board. The utility model is structured in cuboid frame, a right upright plate, a left upright plate are integrated the lower cross board and the upper cross board into a whole. A right-angle upper retaining ring is positioned front upper outside of the right and left upright plate. A step is arranged on the upper restraining ring. The right-angle lower restraining ring is positioned back down outside of the let and right upright board. A rectangle hole with a hemicycle end is arranged at the center of the cross board. The baffle with a step at the center is positioned in front of the cross board, the top surface of the step is semicircular. The step on the baffle is inserted into the rectangle hole of the cross board and forms a round hole at the center. The two end of the baffle is connected with the upright board with fixing bolts. The utility model is suitable for the production condition with thick oil, heavy load, and severe conditions, the utility model can realize the continuous production of polished rod and improve the productivity of oil pump, thus increasing oil output and economic benefits.

Description

The polished rod eye bracing frame

Technical field

The utility model relates to the disconnected polished rod resist technology of a kind of pumpingh well, particularly is a kind of polished rod eye bracing frame.

Background technology

About realizing that the quantity-produced device has four kinds behind the disconnected polished rod of pumpingh well, be respectively " polished rod breaks and takes off safe polished rod eye " at present, the patent No.: ZL89222076.7; " the anti-breaking polished rod eye of polished rod ", the patent No.: ZL200420066791.X; " outstanding rope clip combination ", the patent No.: ZL200420053973.3; These three patented technologies all take to transform the thinking of polished rod eye lower wall, have following defective: the one, and polished rod eye can not be installed during less than 20cm apart from well head when bottom dead centre; The 2nd, the heavy oil wells polished rod easy accident that the stretch bending polished rod takes place of slow following time." modified oil pumper polished rod eye ", the patent No.: ZL200420097040.4, this technology utilizes cylindrical support to add standby polished rod clamp between the polished rod eye upper lower burrs, realizes producing continuously behind the disconnected polished rod, its defective: the one, polished rod clamp setting angle is subjected to the restriction of cylindrical support, easily loses efficacy; The 2nd, heavy oil wells polished rod poor stability of slow following time.Prior art still can not address the above problem preferably.

The utility model content

The purpose of this utility model is exactly at above-mentioned weak point, designs a kind of polished rod eye bracing frame.

The technical scheme that its technical problem that solves the utility model adopts comprises: go up earflap, following earflap, riser, baffle plate, set bolt, transverse slat; It is the cuboid frame construction, left and right riser and upper and lower transverse slat are formed one, earflap is positioned at the front upper place, outside of left and right riser on the right-angle type, and last earflap has a boss, earflap is positioned at the back lower place, outside of left and right riser under the right-angle type, it is semicircular slot that the transverse slat center has an end, the baffle plate that has boss in the middle of being provided with before the transverse slat, boss end face on the baffle plate is semicircle, boss on the baffle plate inserts in the slot of transverse slat, in be formed centrally a circular hole, the baffle plate two ends have set bolt to be connected with riser.

Polished rod eye bracing frame according to the such scheme manufacturing, be installed between polished rod eye and the centralizer, the standby polished rod clamp of middle installation is when polished rod is disconnected in position, clamp lower surface, carrying side, standby polished rod clamp is seated on transverse slat and the polished rod eye, and the realization pumpingh well is produced continuously; To haul lifting rope descending when polished rod polished rod eye of slow following time, can not occur that polished rod eye is descending to be hampered, and the bending of outstanding rope is put the horse head both sides, the accident of stretch bending polished rod; Polished rod eye is along the polished rod axial rotation when turning round when outstanding rope is beaten, because the protection of last earflap, outstanding rope can not deviate from from centralizer, and can guarantee that centralizer and bracing frame rotate synchronously, has improved job stability, has avoided standby side's clamp inefficacy.The utility model is suitable for viscous crude, heavy duty, the abominable working condition of operating mode, and rate when improving oil pumper production increases crude output, has remarkable economic efficiency.

In the accompanying drawing, the last earflap of 1-, earflap under the 2-, 3-riser, the 4-baffle plate, 5-set bolt, 6-transverse slat, 7-centralizer, the 8-horse head, the outstanding rope of 9-, 10-polished rod, the 11-side of carrying clamp, the standby side's clamp of 12-, 13-polished rod eye bracing frame, the 14-polished rod eye, 15-polished rod sealer, D-square hole, the E-circular hole, F-hangs the wire clips groove, the outstanding rope of G-passage.

The specific embodiment

The utility model comprises: go up earflap 1, following earflap 2, riser 3, baffle plate 4, set bolt 5, transverse slat 6; It is the cuboid frame construction, left and right riser 3 is formed one with upper and lower transverse slat 6, earflap 1 is positioned at the front upper place, outside of left and right riser 3 on the right-angle type, and last earflap 1 has a boss, earflap 2 is positioned at the back lower place, outside of left and right riser 3 under the right-angle type, it is semicircular slot that transverse slat 6 centers have an end, the baffle plate 4 that has boss in the middle of being provided with before the transverse slat 6, boss top on the baffle plate 4 is the face semicircle, boss on the baffle plate 4 inserts in the slot of transverse slat 6, in be formed centrally a circular hole E, baffle plate 4 two ends have set bolt 5 to be connected with riser 3.

Mounting method: at first,, lay down polished rod 10 load at the side of stamping, polished rod sealer 15 top clamp; Secondly, the side's of carrying clamp 11 is unloaded pine, centralizer 7 is upwards held up, polished rod eye bracing frame 13 is installed between polished rod eye 14 and the centralizer 7, crooked outstanding rope 9 puts it in the outstanding wire clips groove F, and the boss of earflap 1 is inserted in the outstanding rope passage G of centralizer 7, is positioned at outstanding rope 9 outsides; The 3rd, baffle plate 4 is contained on the transverse slat 6, fixing by set bolt 5; The 4th, in polished rod eye bracing frame 13 square hole D, load onto standby side's clamp 12; The 5th, tighten carrying side's clamp 11, the square clamp of laying down polished rod sealer 15 tops gets final product.
