Problems solved by technology

[0003] However, due to factors such as the complexity of the field test and the high cost, the current experimental research on rock mass anisotropy is mostly based on laboratory tests.
The research object of the indoor test is usually carried out with a certain size of the cylindrical specimen, and the production of the cylindrical specimen is mainly made of natural rock mass or similar materials, and when using similar materials, it is difficult to determine the similarity ratio, and Due to the limitation of indoor conditions, it is difficult to accurately simulate bedding rock mass, so it is more practical to use natural rock mass drilling samples, but due to the irregularity of natural rock mass and the current rock drilling sampling The problem of taking rock samples with different bedding angles, when using natural rock mass to drill batches of bedding rock samples with different angles, there are great difficulties, and there is still no good method that can be simple and quick Obtain batches of bedding rock mass specimens from different angles continuously

Embodiment 1

[0057] see Figure 1-21 , a base of a bidirectional free-rotating rock coring machine, which includes a rotating rock sample tray structure, a spherical hinge support structure, a movable chassis structure and a bottom plate structure.

[0058] Further, the base plate structure includes a support base plate 12 , the support base plate 12 is fixed on the base plate foundation 21 through bolts 15 , and the upper surface of the support base plate 12 defines cross guide rails 11 .

[0059] Further, the movable chassis structure includes a movable bottom plate fixed support 7, the movable bottom plate fixed support 7 is fixed on the support bottom plate 12 through the guide rail 11, and the top of the movable bottom plate fixed support 7 supports the rotating support fixed chassis 2, And through the set bolt 9 and the bolt hole 10, the rotating support fixed chassis 2 is laterally fixed.

[0060] Further, the spherical hinge support structure includes a spherical hinge 3, the uppe...

Embodiment 2

[0067] A rock sampling method is carried out at the base of a bidirectional free-rotating rock coring machine, which includes the following steps:

[0068] S1: First move the fixed chassis 2 of the rotary support, move the fixed chassis of the rotary support to a suitable position on the bottom plate 12 of the support through the roller 6, so that the drill bit of the drilling machine is roughly aligned with the center of the rotary rock sample tray 1, Then four movable floor fixed supports 7 are pushed into the surroundings of the rotary support fixed chassis 2 along the guide rails 11 on the support bottom plate 12, so that the scratched contact surface on the movable floor fixed support 7 is fixed with the rotary support. The lower surface of the chassis 2 is completely fitted, and the No. 1 rotating disk 8 is rotated to lock the four movable bottom plate fixing supports 7 respectively;

[0069] S2: Then pass the fastening bolts 9 on the fixed support 7 of the four movable ...

Abstract

The invention provides a bidirectionally freely rotating pedestal of a rock core drilling machine and a sampling method. The bidirectionally freely rotating pedestal comprises a rotary rock sample tray structure, a spherical hinge support structure, a movable chassis structure and a base plate structure. The pedestal is simple to manufacture, high in precision, safe, environment friendly, and convenient and reliable to operate. According to the invention, the rock sample tray of a sample drilling machine is improved and is allowed to be able to incline so as to facilitate selection of a desired bedding rock sample drilling angel and drilling of rock samples with different bedding inclination angles; moreover, the pedestal is movable, so the positions of rock samples can be conveniently adjusted.

Description

technical field [0001] The invention belongs to the field of civil engineering, and specifically relates to a base of a bidirectional free-rotating rock coring machine, which is suitable for sample preparation of various rock materials. Background technique [0002] In nature, most rock bodies have various geological interfaces, including material differentiation surfaces and discontinuities, such as folds, faults, bedding, bedding, etc., which will make the rock mass show very obvious anisotropy In engineering, the anisotropic characteristics of rock mass often determine the safety of engineering construction and engineering structures. The research on the anisotropic nonlinear characteristics of rock mass has always been a technical problem to be solved in the process of engineering construction. The urgent need for the development of mechanics. [0003] However, due to factors such as the complexity of the field test and the high cost, the current experimental research o...
