Workbench and rock core drilling machine

Abstract

The invention discloses a workbench, which comprises a flat plate (6-1). The workbench is characterized in that a plurality of T-shaped grooves (6-11) are arranged in the upper side surface of the flat plate (6-1) and are distributed in parallel at intervals; a drainage ring groove (6-12) is arranged in the upper side surface of the flat plate (6-1) and communicates with each T-shaped groove (6-11), and a drainage port (6-13) is arranged in the drainage ring groove (6-12); and a plurality of supporting convex strips (6-3) are fixedly arranged on the upper side surface of the flat plate (6-1) and are distributed in parallel at intervals. According to the workbench, a rock block to be subjected to coring can be conveniently fixed, and sewage generated during coring can be discharged in time,and meanwhile, penetration of the rock block and safe coring can be realized. In addition, the invention further discloses a rock core drilling machine.

Description

technical field [0001] The invention belongs to the technical field of rock detection, and in particular relates to a workbench and a rock coring machine. Background technique [0002] Current rock corers (see figure 1 ) includes a drilling rig, a barrel cutter and a worktable, and the barrel cutter is installed on the main shaft of the drilling rig, and the upper end of the barrel cutter is provided with a standard handle, and the main shaft of the drilling rig is equipped with a connecting structure that matches the standard handle. The cylinder cutter quick change between the drilling rig spindles is realized, but the following deficiencies are found during use and analyzed as follows: [0003] First, the current workbench is provided with threaded holes. Since the position of the threaded holes is fixed, when fixing rocks of different shapes and sizes, it is inconvenient and poor in practicability; [0004] Second, when taking coring on the current workbench, water nee...

AI Technical Summary

Problems solved by technology

[0003] First, the current workbench is provided with threaded holes. Since the position of the threaded holes is fixed, when fixing rocks of different shapes and sizes, it is inconvenient and poor in practicability;

[0004] Second, when taking coring on the current workbench, water needs to be added to cool down and lubricate, and there is a lot of sewage, but currently there is sewage flowing everywhere, polluting the environment and other problems;

[0005] The 3rd, present workbench is the support of a rock mass that treats coring with a large horizontal surface, and when barrel cutter is drilling through the rock block to be cored, the lower end cutter tooth of this barrel knife will bump into described flat plate when going down, easily Damage to the cutter and workbench, and at the same time, the problem of not being able to completely penetrate the rock block for coring;

[0006] Fourth, because the drill bit will heat up when the barrel cutter is drilling and coring, it needs to add water to cool down and reduce dust. At present, a water pipe is used to align the drilling position of the barrel cutter and add water to the outside of the barrel cutter. There is water on the outside of the barrel cutter Splashing around, and at the same time, the inner side of the barrel cutter is dry-frictioned with the rock, the reduction and lubrication effect is weak, the resistance is large, and there is a problem of low coring efficiency;

[0007] Fifth, because the drilling rig cannot be displaced, there is a need to move the rock when coring the different positions of the rock blocks placed on the base. Because the rock is heavy, the displacement is unsafe, and it is time-consuming and labor-intensive, and the operation is troublesome;

[0008] Sixth, because the workbench cannot be displaced and adjusted in height, it cannot be placed in a low position, and there is trouble in loading materials. At the same time, it is not convenient to move rocks when taking cores from different positions, and the displacement is unsafe. At the same time, it is time-consuming and laborious, and the operation is troublesome;

[0009] Seventh, the current rock coring machine can only be used for outdoor coring due to its single function, and it is necessary to design a rock coring machine for indoor coring to meet more requirements
