Description
Technical field
The utility model relates to a kind of drill rod centralizing bracket, belongs to the ground instrument equipment technical field of petroleum works.
Background technology
When petroleum system drilling well, underground work, site layout project has standardization requirement, as ground wire bar, colored ribbon bar, warning sign the thin end of the scroll etc. all need into reinforce, general operation is that people's righting, people's hammering enter ground.Existing problems are: energetically during acceleration shock, winter is freezing when serious, coordinate when not tacit, can greatly increase the risk that unexpected hammering is hurted sb.'s feelings.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of drill rod centralizing bracket.
The purpose of this utility model is: with drill rod centralizing bracket, replace the function of artificial righting drill rod, auxiliary people's complete independently hammering drill rod waits related work with entering, subdues security risk, improves speed of application, reduces labour intensity.
A kind of drill rod centralizing bracket, fixed support bar connects recess bar cover, recess bar cover connects movable support rod, movable support rod can move in recess bar cover, and fixed support bar 2 tops connect locating shoulder, and locating shoulder connects rubber hand by screw bolt and nut, the fixed support bar of said structure has 3 pairs, the top of 3 fixed support bars connects breach apical ring, and the bottom of 3 fixed support bars connects breach base ring, and between 3 fixed support bars, interval is 120 °; Breach base ring is identical with breach apical ring aperture pitch and in same direction; Rubber hand opening is U-shaped, and at the symmetrical breach of open circumferential.
The beneficial effect of utility model: replace artificial righting drill rod, auxiliary people's complete independently hammering drill rod waits related work with entering, subdues security risk, improves speed of application, reduces labour intensity.Make simply, be beneficial to popularization.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by the detailed description with reference to below, can more completely understand better the utility model and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model is used for explaining the utility model, do not form improper restriction of the present utility model, as schemed wherein:
Fig. 1 is structural representation of the present utility model;
Below in conjunction with drawings and Examples, the utility model is further illustrated.
The specific embodiment
Obviously, the many modifications and variations that those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1, a kind of drill rod centralizing bracket, fixed support bar 2 connects recess bar cover 9, and recess bar cover 9 connects movable support rod 8, and movable support rod 8 can move in recess bar cover 9, fixed support bar 2 tops connect locating shoulder 6, locating shoulder 6 is connected rubber hand 4 by bolt 5 with nut 7, and the fixed support bar 2 of said structure has 3 pairs, and the top of 3 fixed support bars 2 connects breach apical ring 3, the bottom of 3 fixed support bars 2 connects breach base ring 1
Between 3 fixed support bars 2, interval is 120 °; Breach base ring 1 is identical with breach apical ring 2 aperture pitch and in same direction; Rubber hand 4 openings are U-shaped, and at the symmetrical breach of open circumferential.
Embodiment 2: as shown in Figure 1, and a kind of drill rod centralizing bracket, 50 millimeters of 320 millimeters of breach base ring 1 external diameters, 300 millimeters of internal diameters, high 10 millimeters, breach spacing.Fixed support bar 2 is solid hopkinson bar, 16 millimeters of diameters, 360 millimeters of length.50 millimeters of 120 millimeters of breach apical ring 3 external diameters, 100 millimeters of internal diameters, high 10 millimeters, breach spacing.
Locating shoulder 6 is long 20 millimeters, wide 15 millimeters, thick 2 millimeters, material 45 steel plates, and length is located 8 millimeters of through holes of drill diameter from top to bottom to 10 millimeters of center lines and facilitated bolt 5 to pass, totally three of locating shoulders 6.
Totally three of movable support rods 8, are solid hopkinson bar, 12 millimeters of diameters, 220 millimeters of length, and top has horizontal box thread can connect the handle that there is supporting male thread one end, equal 4 millimeters of the handle square sectional length of side, 30 millimeters of overall lengths.
During assembling breach base ring 1 under, breach apical ring 3 is upper, in breach apical ring 3 lower ends and breach base ring 1 ring, longitudinally weld three fixed support bars 2,120 °, interval, take breach mid point as two fixed support bar 2 symmetries in benchmark left and right, and fixed support bar 2 bottoms are given prominence to 30 millimeters of breach base ring 1 lower ends and are facilitated ground to base oneself upon; Each fixed support bar 2 one sides from top to bottom 100 millimeters locate to start downward parallel welding recess bar cover 9; The axial line of breach base ring 1 and breach apical ring 3 of take is benchmark, at each fixed support bar 2 from top to bottom 90 millimeter places, inner side transverse weld locating shoulder 6, the long extended line to center line of each locating shoulder 6 can be overlapped on the axial line of breach base ring 1 and breach apical ring 3; In the through hole of locating shoulder 6, pass through fixedly rubber hand 4 of bolt 5 and nut 7, the through hole center line of each rubber hand 4 can overlap with the axial line of breach base ring 1 and breach apical ring 3 or approach; In each recess bar cover 9, pack movable support rod 8 bodies of rod into and tighten handle by screw thread, movable support rod 8 can be up and down in groove, and can realize location by handle being proceeded to the recess of recess bar cover 9.
The use procedure of summary drill rod centralizing bracket, contributes to understand the utility model.
Drill rod centralizing bracket stands up on ground, if ground is uneven or increase height, all can adjust by movable support rod 8, and by the handle of movable support rod 8, proceed to the recess realization location of recess bar cover 9.The vertical drill rod that inserts from the through hole of three rubber hands 4 from top to bottom, " U " type through hole of three rubber hands 4 is controlled drill rod and can be not unidirectional not be tilted, and operator's hammering drill rod top makes it reach the degree of depth with entering.Short and the top of drill rod, without reducing, can upwards propose drill rod centralizing bracket; Drill rod is long or top diameter is large, can utilize the elasticity of rubber hand 4 and the breach in the same way of breach base ring 1 and breach apical ring 3 to exit drill rod centralizing bracket.
As mentioned above, embodiment of the present utility model is explained, but as long as not departing from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation is also all included in protection domain of the present utility model.
