[0051] Described planetary gear train 14 comprises circular back plate 15, and circular back plate 15 is used as the base plate of planetary gear train 14, and ...

Embodiment 2

[0053] Embodiment 2, on the basis of Embodiment 1, the described drilling structure includes a drilling 2, the drilling 2 is a through hole opened on the workbench 1, and the workbench 1 passes through the support column located on the side of the drilling 2 3 is integrally connected with a positioning ring 4, the positioning ring 4 is located directly above the drill hole 2 and coaxial with the drill hole 2, the inner wall of the positioning ring 4 is tapped with a positioning ring thread 5, and the positioning ring 4 has a built-in rotating rod 6, The outer wall of the rotating rod 6 is tapped with a rotating rod thread 7, and the rotating rod 6 and the positioning ring 4 are threadedly engaged. A drive screw 9 is engaged, and its engagement method can be compared to the engagement of male and female screws. The drive screw 9 can drive the rotating rod 6 to rotate. The ring 4 rotates up and down, the lower end of the driving screw 9 is coaxially connected with a driven pinio...

Embodiment 3

[0054] Embodiment three, on the basis of embodiment one, the drill pipe 8 is cylindrical, that is, a cylinder with a through hole inside, the inner wall of the upper end is tapped with a drill pipe internal thread 30, and the outer wall of the lower end is tapped. There are drill pipe external threads 31, and the drill pipe external threads 31 of a plurality of drill pipes 8 can be engaged with the drill pipe internal threads 30, and the drill pipe external threads 31 can be threadedly connected with a drill bit 32, and the drill bit 32 is a diamond drill bit. One-piece drill bit, the whole drill bit has no moving parts, simple structure, high strength, high wear resistance and impact resistance. When drilling in soft and medium hard formations, the diamond drill bit has fast speed, more footage and long life. , stable work, fewer downhole accidents, good well quality, etc., the current drilling rigs and others use this kind of drill bit. The upper end of the drill bit 32 is pr...

Abstract

The invention relates to a drilling machine for road construction. The problem that an existing drilling machine cannot change directions and replace rods automatically is effectively solved. According to the technical scheme, the drilling machine comprises a workbench, a drill hole is formed in the workbench, the workbench is integrally connected with a locating circular ring by a supporting column located near the drill hole, and a locating circular ring thread is arranged on the inner wall of the locating circular ring in a tapping mode. A rotating rod is arranged in the locating circular ring, a rotating rod thread is arranged on the outer wall of the rotating rod in a tapping mode, the rotating rod meshes with the locating circular ring in a threaded mode, and a drill rod is connectedto the lower end of the rotating rod in a threaded mode. A driving screw is arranged next to the drill rod in a threaded and meshing mode, the rotating rod can drive the locating circular ring to move rotatably up and down in the locating circular ring, a driven small gear is integrally and coaxially connected to the lower end of the driving screw, and a driving gear ring is arranged outside thedriven small gear in a meshing mode. A helical tooth is arranged outside the driving gear ring, a driven helical gear is arranged next to the driving gear ring in a meshing mode, a driven belt pulleyis integrally connected to the driven helical gear, a planetary gear train is in pin joint with the driven belt pulley, and the planetary gear train is controlled by a control system. The drilling machine for the road construction improves the efficiency of construction work.

Description

technical field [0001] The invention relates to the technical field of drilling machines, in particular to a drilling machine for road construction. Background technique [0002] With the continuous development of modern society, more and more areas have gradually begun to lay roads. However, for some remote areas, the local stratum environment is not suitable for roads due to soft soil and dense small karst caves in shallow underground positions. At this time, it is often necessary to carry out stratum reinforcement grouting on the road planning route first. The first step of the grouting reinforcement method is drilling. Therefore, the drilling machine has become an indispensable construction equipment. [0003] Existing drilling machines are divided into positive circulation drilling rigs and reverse circulation drilling rigs according to the construction process. When the positive circulation drilling rig is working, the mud flows in from the drill pipe and overflows fro...
