Description

Earth electrode drill bit

Technical Field

The utility model relates to a drill bit, especially a drill bit that is used for the earthing pole to punch.

Background

The temporary grounding is needed when the military electronic vehicle is parked and works, the time requirement is short, and the geological condition is complex. The traditional construction method is to use a sledge hammer to drive a steel grounding electrode into the ground, but for an ion grounding electrode and a copper bar grounding electrode, the sledge hammer cannot be used to strike the grounding electrode due to the soft material. At present, a method for digging a pit and punching is adopted, but the problem that the punching is difficult to solve under various geological conditions is always solved, the existing punching equipment has the weight of several tons or even tens of tons, the price of tens of thousands of yuan or even tens of thousands of yuan, and the installation and debugging time is longThe method has the disadvantages of difficult transportation, high cost, and strict requirements on construction environment, and cannot be popularized. On the premise, the installation of the non-driven grounding electrode generally adopts manual excavation or mechanical excavation, and the manual pit digging speed is slow, the time is long, and the labor intensity is high; the mechanical excavation construction work surface is large, if the grounding electrode only needs a hole with the diameter of 60mm and the depth of 2-3 m, but the construction needs to excavate 2.5 m-2.5 m on the ground surface, and the earth and stone have the size of 5m²The construction cost is high, the time is long, and special equipment needs to be carried. Therefore, the mode that above-mentioned earthing pole punched can not be applicable to the requirement that high efficiency punched under the military environment. The existing small drilling machine is also suitable for soft soil, and the drill rod can be stuck when the soil containing gravels, gravels or tree roots is basically incapable of drilling; for the drill bit special for drilling stones, the drill bit can move up and down while drilling, and when the earth is dug, the force of the drill bit cannot be used for punching the grounding electrode. For example, the utility model patent with the application number CN2018211544879, entitled "multi-section combined lengthened drill bit device" discloses a multi-section combined lengthened drill bit device, which consists of a drill bit head, an external thread head iron rod, an internal and external thread head iron rod and an internal thread joint; the drill bit head is formed by vertically cutting off a drill bit rod part by a complete drill bit and is arranged at the leftmost end of the drill bit device; the right-hand member welding of drill bit head external screw thread head iron bar, the right-hand member of external screw thread head iron bar passes through screw-thread fit and connects inside and outside screw thread head iron bar, inside and outside screw thread head iron bar adopts multisection combination and connects gradually through screw-thread fit, multisection the rightmost end of inside and outside screw thread head iron bar passes through screw-thread fit and connects female adapter, female adapter's right-hand member clamp is on the electric drill. Although the patent is also a drill bit for the ground electrode punching, the part of the drill bit for punching is still of an existing structure and is not suitable for geological environments with different hardness or tree roots. In addition, the utility model patent with the name of "diamond anchor rod drill bit" as the application number CN2012202078581 discloses a diamond drill bit, belongs to the diamond tool class, and particularly relates to a mining diamond drill bit. The drill bit consists of a metal cylinder and diamond compact cutting teeth, and the total number of the drill bit is fiveThe diamond compact cutting teeth are distributed in an up-down structure, two of the cutting teeth are fixed at the top end of the metal cylinder in parallel, the other three cutting teeth are uniformly fixed on the side surface of the metal cylinder, and water outlet holes are respectively formed in two sides of the two diamond compact cutting teeth at the top end of the metal cylinder.
