Description

technical field [0001] The invention belongs to the technical field of building construction drilling, and specifically refers to an asymmetric anti-deep jamming drilling device for building construction. Background technique [0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings, or the process of turning the lines on the design drawings into real objects. During the construction process, it is often necessary to drill holes on the ground. [0003] Nowadays, workers usually drill holes on the ground with electric drills, and when the electric drills work, they will generate large vibrations, which will cause collapse and depression along the edge of the drill holes, seriously affecting the quality of the drill holes. Secondly, when drilling holes, the soil The sand and stones in the hole are easy to splash out, causing injuries to the staff. In addition, ...

Problems solved by technology

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a kind of drilling device for asymmetrical anti-deep jamming type construction, in order to solve The drill bit is easily damaged for a long time and needs to be replaced, and the drill bit is deeply sunken in the hole and cannot be taken out when the hole wall bulges or moves. Apply the principle of asymmetry to set an asymmetric drill bit to change the symmetrical shape of the object into an asymmetrical one. The symmetrical structure of the drill bit is replaced with an asymmetric structure with two different radii of curvature. The asymmetric drill bit drills holes, and the diameter of the drill hole exceeds the maximum lateral dimension of the drill bit, which completely solves the technical problem that the drill bit is not easy to take out. Soft and easy to collapse, iron powder and magnetic field are introduced into the field of construction drilling technology, and iron powder is mixed into the soil to change the soil composition. The technical effect of the tight accumulation of soil at the hole, which in turn enhances the hardness of the soil at the hole, and perfectly solves the technical problem that the soil at the hole is easy to collapse. Splash will occur when drilling and may cause personal injury), and a double-layer shock-absorbing anti-splash device is installed to achieve the technical effect of anti-splash and noise reduction

[0006] Further, in order to solve the problem that the drill bit will be stuck in the drill hole and cannot be taken out when the hole wall layer is raised or moved during drilling, the asymmetry principle is used to set the The asymmetrical drill bit changes the symmetrical shape of the object into an asymmetrical one, and replaces the symmetrical structure of the drill bit with an asymmetric structure with two different radii of curvature. The asymmetrical drill bit includes cylinder one, cylinder two and a drill tip, The first cylinder is arranged on the drilled column, the second cylinder is arranged on the drilled column, the first cylinder is tangent to the second cylinder, the diameter of the first cylinder is greater than the diameter of the second cylinder, The drill tip is arranged on the bottom wall of the first cylinder and the second cylinder, the center of mass of the first cylinder and the second cylinder is on the center of the drilling column, and the outer peripheral wall of the first cylinder and the second cylinder There are ribs and grooves, the ribs and grooves are arranged at intervals; two cylindrical faces form the sides of the asymmetric drill, and the two cylindrical faces have different radii of curvature, and the centers of these radii fall on the borehole On the axis of rotation of the column, therefore, the radius of the drilled hole is equal to the large radius of curvature of the cylindrical surface of the drill bit. In order to prevent any vibration from the drill bit during rotation, the center of mass of the asymmetric drill bit is located on the axis of rotation of the drill column, asymmetric Drilling with a drill whose diameter exceeds the maximum lateral dimension of the drill, so that it can be easily removed from the drill if it is stationary
