Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a torpedo drill bit device with steel strand. Background Technology

[0002] In today's large-scale infrastructure construction, high-rise building projects, and underground space development projects, anchoring technology is becoming increasingly important as a key means of ensuring project stability. Traditional construction requires drilling holes first, and then inserting steel strands separately, a cumbersome process that is easily affected by the condition of the borehole wall. Especially under special geological conditions, such as in strata of plain fill, miscellaneous fill, and silty clay, conventional drill bits have low drilling efficiency; in miscellaneous fill strata, rock fragments can easily fall and block the borehole, affecting the drilling progress. Utility Model Content

[0003] The purpose of this utility model is to provide a strip strand torpedo drill bit device in order to solve at least one of the above-mentioned technical problems.

[0004] In a first aspect, this utility model provides a torpedo drill bit device with a steel strand, comprising: a central rod, a pressure plate, and a steel strand. A drill bit is fixedly mounted at the front end of the central rod, and a connecting portion is provided at the rear end of the central rod. A first through hole is provided at the middle position of the pressure plate, and a plurality of second through holes are provided around the first through hole. The central rod is connected to a drill bit motor through the connecting portion. The central rod passes through the first through hole, and the end of the steel strand passes through the second through hole. A compression sleeve is also provided at the end of the steel strand, which is used to clamp the end of the steel strand onto the pressure plate.

[0005] Furthermore, the drill bit is fixed to the front end of the central rod by welding.

[0006] Furthermore, the connecting part includes a fixing ring and a plurality of connecting rods; the fixing ring is fixedly sleeved on the tail end of the central rod, and the plurality of connecting rods are fixedly disposed on the outer wall of the central rod, and the front ends of the plurality of connecting rods are fixedly connected to the fixing ring.

[0007] Furthermore, the fixing ring is fixed to the central rod by welding, and the fixing ring is fixed to the connecting rod by welding.

[0008] Furthermore, the plurality of connecting rods are distributed at equal intervals on the outer wall of the central rod.

[0009] Furthermore, the connecting rod body comprises threaded steel.

[0010] Furthermore, the pressure plate is sleeved on the outside of the central rod and positioned between the drill bit and the fixing ring; the inner diameter of the first through hole is larger than the outer diameter of the central rod and smaller than the outer diameter of the fixing ring.

[0011] Furthermore, the pressure plate comprises a circular steel plate.

[0012] Furthermore, the plurality of second through holes are distributed at equal intervals around the first through hole.

[0013] Furthermore, the inner diameter of the second through hole is larger than the diameter of the steel strand and smaller than the outer diameter of the extrusion sleeve.

[0014] This utility model provides a torpedo drill bit device with steel strand. A pressure plate is set at the torpedo drill bit position to connect the steel strand, integrating the drilling and steel strand introduction into the borehole operation. This reduces construction steps, saves time, and avoids disturbance to the borehole wall caused by secondary operations. Especially under complex geological conditions, it can effectively prevent construction delays caused by problems such as borehole collapse, and alleviate the technical problems of cumbersome procedures and susceptibility to borehole wall conditions in existing technologies.
