Abstract

The utility model discloses a straightener which comprises a supporting stand and a movable sleeve with a sleeve barrel, wherein two hangers for hooking awaiting straightening member bars are arranged on the supporting stand, a top bar between the two hangers is arranged in a threaded hole on the supporting stand via screw thread, the end portion of the top bar is inserted into the sleeve barrel on the movable sleeve, a groove is arranged on the top surface of the movable sleeve, and the top bar is radially provided with a hand handle or a tool-clamping section with regular polygonal cross-section. The straightener has simple structure and convenient use, which is not only can be used for the pumping rod straightening of pumping units, but also can be used for the straightening of other member bars or pipe fittings which need to be straightened.

Description

Straightener
Technical field
The utility model relates to a kind of straightener, is used for the rod member aligning to bending, is specially adapted to the aligning of the sucker rod of used for oil-field oil pumper.
Background technology
Sucker rod on the oil pumper of oil field oil recovery usefulness, it is crooked occurred by the moment of flexure effect, crooked once acquire a certain degree, and will scrap, and has caused cost to raise and the waste of material.
The utility model content
The purpose of this utility model is to provide a kind of straightener, is used for the rod member of bending is aligned.
The utility model adopts following technical scheme: a kind of straightener, comprise a support, two hooks are installed on support are used to hook rod member to be aligned, in the middle of two hooks, there is a push rod to pass through in the rack-mount screw of screw thread, also comprise a kink that has sleeve, the push rod end is inserted in the sleeve on the kink, and the kink end face is fluted, radially is provided with handle on the push rod or is provided with the tool holding section that the cross section is a regular polygon.
This straightener of the present utility model has simple in structurely, easy to use, except that the aligning that can be used in the oil pumping machine oil pumping bar, can also align other rod member that need align or pipe fitting.
Description of drawings
Fig. 1 is the structural representation of straightener of the present utility model.
Fig. 2 is the upward view of straightener shown in Figure 1.
Fig. 3 is the A-A cutaway view of straightener shown in Figure 1.
Fig. 4 is the B-B cutaway view of straightener shown in Figure 1.
Fig. 5 and Fig. 6 are to use view.
The specific embodiment
Below by specific embodiment the utility model is described in further detail, to help understanding content of the present utility model.
As shown in Figures 1 to 4, comprise a support 1 that constitutes by channel-section steel, installing 1 on support has two hooks 2 to be used to hook rod member to be aligned, in the middle of two hooks 2, have in a push rod 3 screw rack-mount by screw thread, also comprise a kink 4 that has sleeve, the push rod end is inserted in the sleeve on the kink 4, the fluted 4b of kink 4 end faces, push rod 3 is provided with perpendicular handle (omitting among the figure), perhaps being provided with the cross section is the tool holding section 3a of regular polygon, so that with tool holdings such as spanners and rotate push rod 3.
In order to adjust the spacing of two hooks 2 easily according to the degree of crook of waiting to align rod member and diameter, two hooks 2 are in two slotted hole 1a that are through on the support 1, the part that slotted hole 1a is passed in the hook end is a straight bar section, and the end of this straight-bar end is equipped with nut 5 and deviates to prevent to link up with in 2 the slotted holes from the support 1.
For preventing that kink 4 from coming off or lose from push rod 3, as shown in Figure 4, also be fixed with a snap ring 4a on the kink 4, circular hole center on the snap ring 4a is coaxial relative with the endoporus center of the sleeve of kink 4, part annular on the push rod 3 between sleeve and snap ring is provided with protruding 3b, and the hoop size of protruding 3b part is greater than the Circularhole diameter of snap ring 4a.Projection 3b can adopt solder joint as shown in Figure 4, also can be an annulus.
Positive four polygons or orthohexagonal tool holding section 3a are positioned at the end of a threaded end on the push rod 3, are provided with in the end and can use various spanners easily, and for example box spanner is particularly pneumatic or electric wrench.
Support 1 is a channel-section steel, and channel-section steel intensity is difficult for flexural deformation well, and in light weight, simple in structure, is convenient to fix.Screw on the support can be for being welded on the screw of the nut 1b on the channel-section steel.
Its occupation mode as shown in Figure 5 and Figure 6, with the rod members such as sucker rod 10 of bending with sweep in kink 4 and embedding are pressed in arc groove on the kink 4, hook rod member 10 from both sides with two hooks 2, rotate push rod 3 with instrument or handle, utilize the thread matching structure of push rod 3 and support 1, push rod 3 is ejected to the direction of rod member 10, push rod 3 applies an active force by kink to rod member 10, the active force that utilizes hook 2 and push rod 3 to produce, gradually rod member 10 is pushed up until state shown in Figure 6, reach the purpose of aligning.Push rod utilizes the principle of screw jack, can produce enough top power.This straightener mainly is made up of a support, two hooks and push rod and kink, and is simple in structure, is easy to make, and cost is low, and easy to use.
