Abstract
An auxiliary tool for taking out a crank pin of a beam-pumping unit comprises a striking head (1), a bolt (2) and a supporting barrel (3). The auxiliary tool for taking out the crank pin of the beam-pumping unit is characterized in that the supporting barrel (3) of the auxiliary tool for taking out the crank pin of the beam-pumping unit is of a one-stair-shaped cylindrical structure, inner threads matched with threads of the crank pin are arranged at the left end of the supporting barrel (3), a threaded through hole is formed in the middle of the right end of the supporting barrel (3), the bolt (2) is symmetrically arranged in the threaded through hole, the T-type cylindrical striking head (1) is symmetrically provided with guide grooves (A), the striking head (1) is inserted into the supporting barrel (3), and the bolt (2) enters the guide grooves (A). The auxiliary tool for taking out the crank pin of the beam-pumping unit is simple in structure and safe in the operation of disassembling the crank pin, saves time and labor, effectively protects the threads of the crank pin, prevents the threads from being damaged, is short in downtime, avoids a sand-blocked lay shaft caused by a well with serious sand flow, reduces expenses for oil well operation, improves oil extraction time efficiency, increases crude output and improves economic benefits of an oil field.
Description
Technical field
The utility model relates to the oil field beam pumping unit and changes the crank-pin aid, particularly is that a kind of beam type oil pumping machine crank pin takes out aid.
Background technology
At present, the manufacturing parameter of the widely used beam pumping unit in oil field is: pump footpath, stroke, jig frequency.Stroke in three parameters refers to deep well pump piston distance up and down reciprocatingly.The manufacturing parameter that can adjust has stroke and jig frequency on the ground, is to realize by the eyelet of adjusting the diverse location of crank-pin on crank in adjusting stroke procedure.This shows that adjusting stroke just must take out oil pumper both sides crank-pin, also must the protection screw thread in taking out the crank-pin process.Because crank-pin is that the conical surface contacts with the crank lining, nut is fixed, and needs to knock the screw thread position with sledgehammer in the taking-up process, takes out crank-pin.Because crank-pin is that the conical surface contact with the crank lining, nut is fixed, and does not allow to be coated with butter when mounted again, so its contact is very tight, unloads the crank-pin power of giving up very much, and causes the crank-pin thread damage easily, consequently stops the well overlong time, causes the sand card well of lying.There is potential safety hazard in operation, occurs casualty accident often.
Summary of the invention
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, designs a kind of beam type oil pumping machine crank pin and takes out aid.
The utility model is realized by following technical proposals:
The utility model comprises: bump head, bolt, support tube.The support tube that its beam type oil pumping machine crank pin takes out aid is one-level stepped cylinder shape structure, left end is provided with the internal thread that matches with the crank-pin screw thread, be provided with tapped through hole in the middle of the right-hand member, symmetry is being adorned bolt in the tapped through hole, the cylindric bump head of T-shape is arranged with gathering sill, the bump head inserts support tube, and bolt enters in the gathering sill.
The bump left end that above-mentioned beam type oil pumping machine crank pin takes out in the aid is semicircle or conical, and the right-hand member end face is plane or semicircle.
The beneficial effects of the utility model are: simple in structure; unload the crank-pin handling safety; time saving and energy saving, effectively protect the crank-pin screw thread, prevent thread damage; downtime is short; the serious well of avoiding shaking out causes the sand card well of lying, and reduces the oil well operating cost, improves rate when recovering the oil; increase crude output, improve the oilfield economic benefit.
Description of drawings
Fig. 1-the utility model The field master looks and partly cuts open structural representation.
Among the figure, 1. clash into head, 2. bolt, 3. support tube, 4. crank-pin, 5. crank; A. gathering sill.
The specific embodiment
Below in conjunction with accompanying drawing enforcement of the present utility model is further elaborated:
The beam type oil pumping machine crank pin takes out aid and is made up of bump 1, bolt 2, support tube 3.The support tube 3 that its beam type oil pumping machine crank pin takes out aid is one-level stepped cylinder shape structure, left end is provided with the internal thread that matches with the crank-pin screw thread, be provided with tapped through hole in the middle of the right-hand member, symmetry is being adorned bolt 2 in the tapped through hole, the cylindric bump of T-shape 1 is arranged with gathering sill A, bump 1 an insertion support tube 3, bolt 2 enters in the gathering sill A.When transferring stroke or changing crank-pin 4, crown nut is unloaded, with support tube 3 and being threaded at crank-pin 4, support tube 3 head-on collision is tapped the head and 1 is played centralizing function, by bolt 2 guiding, knock bump 1 with sledgehammer then, deviate from from the crank lining crank-pin 4 stressed backs.
Claims (2)
1. a beam type oil pumping machine crank pin takes out aid, comprising: bump head (1), bolt (2), support tube (3); It is characterized in that: the support tube (3) that described beam type oil pumping machine crank pin takes out aid is one-level stepped cylinder shape structure, left end is provided with the internal thread that matches with the crank-pin screw thread, be provided with tapped through hole in the middle of the right-hand member, symmetry is being adorned bolt (2) in the tapped through hole, the cylindric bump head of T-shape (1) is arranged with gathering sill (A), bump head (1) inserts support tube (3), and bolt (2) enters in the gathering sill (A).
2. beam type oil pumping machine crank pin according to claim 1 takes out aid, it is characterized in that: described bump head (1) left end is for semicircle or conical, and the right-hand member end face is plane or semicircle.
