Description
Technical Field
The utility model relates to a dig rig accessory field soon, specifically indicate a dig wear-resisting ring for drilling rod soon.
Background
The rotary drilling rig is a construction machine suitable for hole forming operation in building foundation engineering. The rotary drilling rig is mainly suitable for construction of soil layers such as sandy soil, cohesive soil, silty soil and the like, is widely applied to construction of various foundation foundations such as cast-in-place piles, continuous walls, foundation reinforcement and the like, and is an important component of the rotary drilling rig, and the working performance of the rotary drilling rig is directly related to the working state of the rotary drilling rig. The drill rods of the rotary drilling rig are generally embedded together by a plurality of sleeves and comprise a first section of drill rod, a middle drill rod and a tail section of drill rod. The end of the last section of drill rod that is close to the square head is equipped with the dish of draining, and in digging the drilling rod work process soon, the interior tooth section of other sections drilling rods constantly bears friction and impact with the dish of draining when interact, causes the wearing and tearing of interior tooth section and dish of draining, makes to dig the drilling rod soon and receives the life-span reduction, causes the waste of resource, and cost of maintenance increases, the time limit for a project extension.
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 wear-resisting ring for drilling rod soon.
In order to solve the technical problem, the utility model provides a technical scheme is a dig wear-resisting ring for drilling rod soon: the device comprises a circular plate, wherein a through hole is formed in the middle of the circular plate; a plurality of arc-shaped holes are formed between the outer edge and the inner edge of the circular plate and are arranged along the circumference of the circular plate in an array manner; the outer diameter of the circular plate is matched with the diameter of a water drain disc of the rotary drilling rod, and the diameter of the through hole is matched with the outer diameter of a tail section rod of the rotary drilling rod; the circular plate is made of wear-resistant metal materials.
As a refinement, the thickness of the circular plate is 20 mm.
As a modification, the circular plate is made of NM500 steel plate.
As an improvement, the number of the arc-shaped holes is not less than 3.
As an improvement, the arc-shaped holes are rounded in outline and have no edges and corners.
Compared with the prior art, the utility model the advantage lie in: the utility model discloses can protect the interior tooth section of digging the drilling rod soon and the dish that drains not receive wearing and tearing, the extension is dug the life of digging tooth section in the drilling rod soon and the dish that drains, simple structure, and it is convenient to make, and is with low costs, and the size is confirmed according to actual need, can be used to digging the drilling rod soon of multiple model, and the suitability is strong.
