Description
Technical field
The utility model relates to exploration engineering field, specially a kind of auxiliary holding device for drill machine with casing.
Background technique
With the rapid development of industry and building cause, exploration engineering application field is increasingly widened, and drill machine with casing is because of it
It is at low cost, security performance is high is used widely, casing drilling is to replace drilling rod to apply torque and bit pressure to drill bit using casing,
Realize that bit and drilling, entire drilling process do not use drilling rod, drill collar etc., drill bit is being covered using wirerope pulling
Drill bit lifting is realized in pipe, that is, is realized and do not mentioned brill replacement bit drilling tool, reduce and make a trip and the contingencies such as blowout, bit freezing,
In the prior art, casing is installed among power head and clamper and clamper has the function of clamping and unloading casing, but
Since gravity influences, the slips of casing and clamper is not easy coaxial, causes to swing, be unfavorable for constructing in this way goes on smoothly, very
To the generation that will lead to safety accident.
Summary of the invention
The purpose of this utility model is to provide a kind of auxiliary holding devices for drill machine with casing, to solve above-mentioned technology
The problem of background proposes.
To achieve the above object, the utility model provides the following technical solutions, a kind of auxiliary clamping for drill machine with casing
Device, including clamper, aperture centralizer and auxiliary holder, described clamper one end pass through bolt and pin shaft and aperture righting
Device one end connects, and the aperture centralizer is made of righting restocking and righting undercarriage, and righting restocking one end is equipped with lifting bolt, together
Heart hole is located among the centralizer of aperture, and righting idler wheel has 4 and is located in concentric holes, and roller shaft has 4 and rolls respectively with righting
Wheel is connected, and the aperture centralizer other end connects with auxiliary holder.
Preferably, the auxiliary holder is made of upper clamp and lower clamp, and upper clamp one end is equipped with lifting bolt, upper folder
Slips is separately installed on body and lower clamp, slips upper and lower ends are separately installed with bolt.
Compared with prior art, the utility model has the beneficial effects that when drill machine with casing is run, by weight when bore angle is big
Power influences, and casing easily swings, is connected by aperture centralizer with clamper one end by bolt with pin shaft, aperture centralizer
Righting restocking and righting undercarriage gripping sleeve, by the lifting bolt adjusting elasticity degree in righting restocking, in the centralizer of aperture
Between concentric holes be used to adjust the position of righting idler wheel, to meet the casing of different-diameter, guarantee that the revolution of casing when drilling is fixed
The heart, auxiliary holding device are mounted on the centralizer of aperture, and casing has axial thrust load in hole, are needed after unsnatching casing screw thread auxiliary
Clamper is helped to step up casing, slips and casing-contact on the upper clamp and lower clamp of auxiliary holder, by adjusting upper clamp
The tightness of two clamps, the slips on clamp are adjusted with the bolt at lower clamp both ends and the lifting bolt of upper clamp one end
Friction can be increased, enhance the crystallized ability of clamp, the utility model is utilized aperture centralizer and is felt relieved to casing, together
Axis, while auxiliary holder prevents casing from scurrying out or falling into hole out of hole, hole inner sleeve righting idler wheel uses bronze material,
Wearability is high, will not rub with casing and generate spark, meet safety requirements, and the slips on auxiliary holder on lower clamp is by tearing open
Unloading installation bolt can freely replace, and improve work efficiency.
