Description

Technical Field

[0001] The invention relates to the technical field of building construction tools, and in particular to a non-swing auxiliary drill rod used for washing holes of a super-large beam tie rod. Background Art

[0002] At the construction site, drilling and hole washing are required before and after pouring to meet the construction quality requirements. Especially in some wider and thicker beam structures, deep holes are required. The current drill rod length is generally around 40cm. Drilling holes deeper than 40cm cannot be completed in one go. If the object is penetrated twice, problems such as misalignment and misaligned holes are likely to occur, making it difficult to complete the construction smoothly. At the same time, the drill rod is easily damaged during the drilling and hole washing process, which greatly increases the construction cost.

[0003] Therefore, the existing drilling and washing construction has areas that need to be improved urgently. It is necessary to optimize and improve the construction process and tools, improve the smoothness of the construction process, reduce damage to tools during construction, and increase the service life of tools. Therefore, it is necessary to propose a more reasonable technical solution to solve the deficiencies in the existing technology. Summary of the invention

[0004] In order to solve the defects of the prior art mentioned above, the present invention provides a swing-free auxiliary drill rod for washing holes of super-large beam pull rods, which is provided with a high-strength rod body. The length of the rod body is increased and holes with greater depths can be drilled. At the same time, the damage to the rod body can be reduced, saving construction costs.

[0005] In order to achieve the above object, the technical solution specifically adopted by the present invention is:

[0006] A swing-free drill rod for washing holes of super-large beam pull rods comprises a rod body, the length of the rod body is greater than or equal to 90 cm, and the diameter of the rod body is 10 mm to 20 mm. A drill bit is arranged at the front end of the rod body, and a connecting part for connecting to a driving drill is arranged at the rear end of the rod body; the diameter of the drill bit is greater than the diameter of the rod body, and a slag removal structure protruding from the surface of the rod body is arranged on the rod body.

[0007] The drill rod disclosed above, by using the rod body as the main body of the drill rod, can provide drilling construction of a longer length. During the construction process, ultra-long and ultra-deep drilling and hole washing operations can be completed in one construction. At the same time, the ash and other materials in the hole can be discharged through the slag removal structure, thereby reducing the risk of blockage, improving the safety level during the drilling and hole washing process, avoiding damage to the drill rod, and reducing construction costs.

[0008] Furthermore, the drill bit structure used in the present invention is not limited to a single one, and it can be constructed into a variety of feasible structures and selected from them. For example, a columnar drill bit can be used in some schemes to facilitate hole cleaning, and a conical drill bit can be used in some schemes to facilitate drilling. Specifically, the present invention optimizes and cites one of the feasible options: the front end of the drill bit is the drilling part, and the rear part is the connecting part and is connected to the rod body; the diameter of the drill bit gradually increases from the front end to the middle part, and the diameter gradually decreases from the middle part to the rear part, and the rear part of the drill bit includes a cylindrical section and is connected to the rod body. When such a scheme is adopted, the overall structural integrity of the drill bit is better, which can meet the needs of both drilling and hole cleaning.

[0009] Furthermore, in the present invention, the overall structure of the drill bit can be constructed in a variety of forms, and an optimization is made here and one feasible option is given: the drill bit adopts a smooth arc transition from the front end to the middle part, and from the middle part to the rear part. When such a solution is adopted, the overall external contour of the drill bit is similar to a spindle, and the front end of the drill bit can be set as a vertical section, which is convenient for cutting and drilling.

[0010] Furthermore, in order to further improve the drilling efficiency, an optimization is made here and one feasible option is given: a double-helix or triple-helix drilling groove is provided on the drill bit. When such a solution is adopted, the drilling groove can be constructed as an arc groove or a conical groove.

[0011] Furthermore, in order to improve the overall strength of the drill bit, its structure is optimized so that the length of the drill bit is kept within a certain range. Here, optimization is performed and one feasible option is given: the length of the drill bit is 15 cm to 20 cm.

[0012] Furthermore, the rear end of the rod body is used to connect to a hand-held pneumatic drill, which is connected and fixed by a connecting portion and rotates and drills under the drive of the hand-held pneumatic drill. Here, an optimization is made and one of the feasible options is given: the connecting portion includes a fitting plane, a fitting elliptical surface or a connecting transverse hole. When such a solution is adopted, the fitting plane or the fitting elliptical surface is only one of the fitting surface structures, and the drill rod rotates through the fitting and transmission torque between the surfaces.

[0013] Furthermore, the slag removal structure used in the present invention is not limited to a single one, and it can be constructed into a variety of feasible structures and selected from them. For example, in some schemes it can be constructed into a spiral groove structure, and in some schemes it can be constructed into a plate-like structure. Here, it is optimized and one of the feasible options is given: the slag removal structure includes a spiral protrusion structure extending along the length direction of the rod body.

[0014] Furthermore, when the spiral protrusion structure is used as the slag removal structure in the present invention, the spiral protrusion structure includes a single spiral structure or a double spiral structure; and the spiral protrusion structure is continuously arranged on the rod body.

[0015] Furthermore, the spiral protrusion structure is not limited to a single one. Here, it is optimized and one feasible option is given: the spiral protrusion structure includes a convex strip, the surface of the convex strip is an arc surface, and the convex strip is extended from one end of the rod body to the other end of the rod body.

[0016] Furthermore, when drilling with a drill rod, the drill bit is the most easily damaged part. In order to facilitate maintenance, the present invention optimizes and improves the structure of the drill bit and the drill rod and provides the following feasible option: the rod body and the drill bit are connected to each other and are detachable. When such a solution is adopted, when the drill bit is damaged, the drill bit can be replaced and the drill rod can be reused.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The drill rod disclosed in the present invention is connected and extended by a long rod body, which can achieve greater depth of drilling and cleaning, reduce the inconvenience of drilling and cleaning construction, and at the same time reduce the probability of damage to the drill rod and increase the service life of the drill rod, which not only improves the construction efficiency but also reduces the construction cost.
