Abstract
The utility model proposes oil pumping rod centering device mounting clamp.Oil pumping rod centering device mounting clamp, comprise expansion link, expansion link both sides are respectively equipped with T-shaped screw rod, being processed into one section of cross section outside T-shaped screw rod is foursquare square toes, each T-shaped screw flight connects T-nut, the side of each T-nut is fixedly connected with an opening block, each T-nut top is fixedly connected with a support arm, be connected through the hinge together after two support arms extend to opening block direction, opening block has open slot along expansion link axis direction, opening direction is positioned at below, the width of open slot is greater than the diameter of sucker rod, be less than the diameter of oil pumping rod centering device, expansion link both sides are respectively equipped with T-shaped screw rod, two T-shaped screw flight rotation directions are contrary.This oil pumping rod centering device mounting clamp utilizes left-right rotary T-shaped screw thread as propulsive mechanism, utilizes chain connection to fix T-nut, has installation rate fast, installs great efforts, reliable operation, the feature of convenient disassembly, favourablely promotes the use of.
Description
Technical field:
The utility model relates to construction tool jig field, oil field, is specifically related to oil pumping rod centering device mounting clamp.
Background technology:
For solving rod-pumped well side-abrasion of rod string problem, oil pumping rod centering device is used widely in oil well production.But centralizer needs in-site installation before going into the well, install centralizer is all manually pound with the ironware such as spanner, pipe wrench in the past, and efficiency is lower, and fragile centralizer, easily pounds hand, there is potential safety hazard.
Utility model content:
In order to solve the problem, the utility model is intended to propose a kind of oil pumping rod centering device mounting clamp.
The technical solution of the utility model is: oil pumping rod centering device mounting clamp, comprise expansion link, expansion link both sides are respectively equipped with T-shaped screw rod, being processed into one section of cross section outside T-shaped screw rod is foursquare square toes, each T-shaped screw flight connects T-nut, the side of each T-nut is fixedly connected with an opening block, and each T-nut top is fixedly connected with a support arm, is connected through the hinge together after two support arms extend to opening block direction.
Described opening block, it has open slot along expansion link axis direction, and opening direction is positioned at below, and the width of open slot is greater than the diameter of sucker rod, is less than the diameter of oil pumping rod centering device.
The utility model has following beneficial effect: this oil pumping rod centering device mounting clamp utilizes left-right rotary T-shaped screw thread as propulsive mechanism, utilizes chain connection to fix T-nut, has installation rate fast, great efforts are installed, reliable operation, the feature of convenient disassembly, favourablely promotes the use of.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is upward views of accompanying drawing 1.
1-T shape nut in figure, 2-expansion link, 3-T shape screw rod, 4-square toes, 5-opening block, 6-support arm.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in Fig. 1 composition graphs 2, oil pumping rod centering device mounting clamp, comprise expansion link 2, expansion link 2 both sides are respectively equipped with T-shaped screw rod 3, and being processed into one section of cross section outside T-shaped screw rod 3 is foursquare square toes 4, get final product rotating extensible arm 2 with spanner, each T-shaped screw rod 3 is threaded T-nut 1, the side of each T-nut 1 is fixedly connected with an opening block 5, and each T-nut 1 top is fixedly connected with after a support arm 6, two support arms 6 extend to opening block 5 direction and is connected through the hinge together.
Described opening block 5, it has open slot along expansion link 2 axis direction, and opening direction is positioned at below, and the width of open slot is greater than the diameter of sucker rod, is less than the diameter of oil pumping rod centering device, for through sucker rod, blocks oil pumping rod centering device.
The thread rotary orientation that described expansion link 2 both sides are respectively equipped with T-shaped screw rod 3, two T-shaped screw rods 3 is contrary, and left-handed and screw rod that is dextrorotation can make the stretching speed of expansion link 2 improve two times.
When work, opening block is enclosed within sucker rod from top by pliers, oil pumping rod centering device is placed on inside opening block, spanner is utilized to screw expansion link, two T-nuts are close, opening block compressing oil pumping rod centering device enters installation site, unscrews expansion link, unloads pliers, finish the work, this oil pumping rod centering device mounting clamp utilizes left-right rotary T-shaped screw thread as propulsive mechanism, utilizes chain connection to fix T-nut, has installation rate fast, great efforts are installed, reliable operation, the feature of convenient disassembly, favourablely promotes the use of.
