Abstract
The utility model discloses an ejector for replacement of a crank pin, which is characterized by comprising movable bearing seats, bearing connecting rods, a lifting jack, a lifting jack bearing plate and a lifting jack bracket, wherein the lifting jack bracket and adjusting holes are arranged on the lifting jack bearing plate; the lifting jack is mounted on the lifting jack bracket; and one end of each bearing connecting rod is provided with an adjusting lead screw and an adjusting screw nut, and is connected with the lifting jack bearing plate through one adjusting hole, and the other end of the bearing connecting rod is connected with one movable bearing seat through a pin. According to the ejector, the lifting jack effectively solves the problems that the conventional beam-pumping unit is complicated in processes such as the stroke adjustment and the crank pin replacement, consumes time and labor, and is low in coefficient of safety. Compared with the prior art, the ejector has the advantages that the operation is simple, the safety and the labor conservation are achieved, the operation procedure is simplified, the oil pumping unit crank shaft pin difficult to dismantle in the past is easily dismantled, and the well opening time ratio of a rod-pumped well is improved.
Description
Technical field
The utility model relates to the oil production equipment of petroleum industry, particularly is applicable to the instrument that beam pumping unit replacing crank pins is used.
Background technology
At present, the most of beam pumping unit that adopts of Shengli Oil Field oil production equipment carries out work, and equipment is in the wild environment; Because crank pins is not changed for a long time, cause rust dead, cause crank pins and crank corrosion to become one; Each crank pins of changing all need consume a large amount of manpowers and time; Cause the engineering time long,, be prone to cause the problem of well of lying if shake out or heavy oil wells.
The utility model content
The technical problem that the utility model will solve is for overcoming above-mentioned deficiency, and provides a kind of simple in structure, easy to operate, safe and reliable crank pins to change backing-out punch.
The utility model is taked following technical measures: a kind of crank pins is changed backing-out punch; Comprise activity load-bearing seat, load-bearing connecting rod, jack, jack bearing plate, jack bracket; Said jack bearing plate is provided with jack bracket and adjustment hole, and jack is installed on the jack bracket, and load-bearing connecting rod one end has regulates leading screw and adjusting nut; Be connected with the jack bearing plate through adjustment hole, the other end is connected with activity load-bearing seat through pin.
The beneficial effect of the utility model be utilize that jack has solved effectively that present beam pumping unit is transferred stroke, changed the crank pins complex procedures, time and effort consuming, problem that safety coefficient is low.Compared with prior art, have simple to operately, safety labor-saving has been simplified operation sequence, can make originally comparatively that the dismantlement work of the oil pumping machine crank pin of difficulty becomes simple, advantage such as rate when having improved the driving a well of rod-pumped well.
Description of drawings

Fig. 2 is the utility model course of work structural representation
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to detail.
As shown in the figure; A kind of crank pins is changed backing-out punch, comprises activity load-bearing seat 1, load-bearing connecting rod 3, jack 9, jack bearing plate 5, jack bracket 8, and said jack bearing plate 5 is provided with jack bracket 8 and adjustment hole 4; Jack 9 is installed on the jack bracket 8; Load-bearing connecting rod 3 one ends have regulates leading screw 7 and adjusting nut 6, is connected with jack bearing plate 5 through adjustment hole 4, and the other end is connected with activity load-bearing seat 1 through pin 2.
The concrete use of the utility model is, and is as shown in Figure 2, earlier beam type oil pumping machine crank 11 is parked in the angle of being convenient to operate after; Again with two activity load-bearing seats 1 of this device with pin 2 be the center revolve turn 90 degrees after; Inboard by crank pins through crank hole 12, again activity load-bearing seat 1 is resetted and hang over crank hole 12 outsides, load-bearing connecting rod 3 is regulated suitable lateral separation through adjustment hole 4; Radial distance is then regulated on adjusting leading screw 7 by adjusting nut 6; Hydraulic jack 9 is placed on the jack bracket 8, ejects end and withstand on the crank pins 10 screw thread ends and suppress, will reach the purpose of laborsaving safe and efficient taking-up crank pins 10 like this.
The utility model jack bracket 8 is designed to the semicircle arcuation; The support hydraulic jack 9 safely and effectively; And design with the circular arc center of circle be the axle center can 360 the degree rotation, no matter crank 11 is on any position, makes jack bracket 8 remain level and holds hydraulic jack 9; Increase effective support area, improved its security.It is that the center is revolved and turn 90 degrees that activity load-bearing seat 1 is designed to pin 2, after resetting during use, can hang over the crank hole outside safely and effectively to bear the pulling force that backing-out punch produces.
The utility model is not limited to the above specific embodiment, and every other embodiments that drawn by those skilled in the art's technical scheme according to the present invention belong to the scope of protecting of the utility model equally.
Claims (3)
1. a crank pins is changed backing-out punch; It is characterized in that comprising activity load-bearing seat, load-bearing connecting rod, jack, jack bearing plate, jack bracket; Said jack bearing plate is provided with jack bracket and adjustment hole, and jack is installed on the jack bracket, and load-bearing connecting rod one end has regulates leading screw and adjusting nut; Be connected with the jack bearing plate through adjustment hole, the other end is connected with activity load-bearing seat through pin.
2. crank pins according to claim 1 is changed backing-out punch, it is characterized in that said activity load-bearing seat is that the center can be revolved and turn 90 degrees with the pin.
