Description
Technical Field
The utility model relates to a dig drilling rod accessory field soon, specifically indicate a dig uide bushing for drilling rod soon.
Background
The rotary drilling rig is a construction machine for boring operation in building foundation engineering. Dig the drilling rod soon and be the execute component when the pore-forming operation, the drilling rod is generally dug soon to the current and install buffer spring on the core festival, buffer spring is located to drain the dish and holds and hit between the dish, the protection drain the dish and hold and hit the dish, increase of service life's purpose has been reached, in order to facilitate placing buffer spring and reduce the gap between buffer spring and the core festival, often install the uide bushing on the core festival, the uide bushing is located to drain the dish and holds and hit between the dish, current uide bushing is when using, the gap between buffer spring and the core festival is still great, and the uide bushing is not pleasing to the eye.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome the defect of above-mentioned technique, provide a dig uide bushing for the drilling rod soon.
In order to solve the technical problem, the utility model provides a technical scheme is a dig uide bushing for drilling rod soon: the device comprises a sleeve, wherein one end of the sleeve is provided with an annular boss; the other end of the sleeve is provided with notches along the circumferential array, the end, deep into the sleeve, of each notch is arc-shaped, the width of each notch is not less than the width of a key strip on a core section of the rotary drilling rod, the thickness of the sleeve is not less than the protruding height of the key strip on the core section of the rotary drilling rod, and the number of the notches is 3.
As an improvement, the outer edge of the sleeve far away from the annular boss is provided with a chamfer.
As the improvement, the outer edges of the two ends of the annular boss are provided with chamfers.
As an improvement, the sleeve and the annular boss are made of steel.
Compared with the prior art, the utility model the advantage lie in: the utility model discloses when making the flash joint reduce between buffer spring and the core festival, simple to operate makes the overall structure when digging the drilling rod assembly soon compacter, reduces buffer spring fracture phenomenon, increases the pleasing to the eye degree of outward appearance.

Detailed Description
The following combines the attached drawing to do further detailed description to the utility model relates to a dig uide bushing for drilling rod soon.
With reference to the attached drawings 1-5, the guide sleeve for the rotary drilling rod comprises a sleeve 1, wherein one end of the sleeve 1 is provided with an annular boss 2; the other end of the sleeve 1 is provided with notches 3 along the circumferential array, the end, deep into the sleeve 1, of each notch 3 is arc-shaped, the width of each notch 3 is not smaller than the width of a key strip on a core section of the rotary drilling rod, the thickness of the sleeve 1 is not smaller than the protruding height of the key strip on the core section of the rotary drilling rod, and the number of the notches 3 is 3.
As a modification, the outer edge of the sleeve 1, which is far away from the annular boss 2, is provided with a chamfer.
As an improvement, the outer edges of the two ends of the annular boss 2 are provided with chamfers.
As an improvement, the sleeve 1 and the annular boss 2 are made of steel.
The utility model discloses when concrete implementation, overlap buffer spring in the sleeve pipe 1 outside, wherein buffer spring's external diameter is not restricted to the external diameter of loop type boss 2, earlier with the uide bushing on the core festival of digging the drilling rod soon, loop type boss 2 is close to the square head, simple to operate, follow-up tailor welds the part key strip that makes on the core festival and stretches into notch 3, after with buffer spring cover on the uide bushing when assembling to make overall structure compacter, reduced and dug the damage of digging the drilling rod during operation to buffer spring soon.
The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
