Embodiment 1

[0034] Such as Figure 1 to Figure 4 As shown, this embodiment provides a miniature full-section drilling layout device for model testing, the drilling layout device mainly includes three parts: a track mechanism, a drilling mechanism and a controller, wherein the drilling mechanism is arranged on the track mechanism And move along the track mechanism, thereby adjusting the whole drilling mechanism to move to the full-section working position of the model experiment area. The drilling mechanism is the main operating part, which includes a circular track part, a radial track part, a drill head and a support part. The two ends of the radial track part are located on the circular track part and can rotate circumferentially along the circular track part. The drill bit The part is installed on the radial track part and can move linearly along the radial track part. The support part is located outside the ring track part to fix the whole drilling mechanism. The controller is respect...

Embodiment 2

[0043] A miniature full-section drilling arrangement device for model testing, the structure is as described in Example 1, the difference is that: three circles of concentric track grooves 12 are opened on the annular guide rail 3 . Later, radial guide rails 4 with different diameters can be selected according to different experimental models, and the high-strength bolts 14 at both ends of the radial guide rail 4 can be fixedly connected to the driven flywheel 16 through the corresponding track grooves 12, so as to realize the full range of different model areas. section work.

Embodiment 3

[0045] A method for using a miniature full-face drilling arrangement device for model testing, using the drilling arrangement device described in Embodiment 1, and its specific operation process is as follows:

[0046] (1) Lay the track mechanism in the model test area. According to the distance that the drilling mechanism needs to travel, you can choose a multi-unit track mechanism to connect it. Select a suitable high-strength drill bit 6 to install on the micro motor 5 according to the experimental requirements;

[0047] (2) The whole drilling mechanism is placed on the track mechanism, the pulley 9 is placed in the strip rail groove 11, and then the whole drilling mechanism is moved to the work area of ​​the model test;

[0048] (3) After the drilling mechanism reaches the work area, the controller 8 controls the support part 7 to start, and the telescopic arm 15 (piston rod) of the servo electric cylinder stretches out to lift the drilling mechanism in the model test tunn...

Abstract

The invention relates to a miniature full cross section drill hole arrangement device for model test and application thereof. The device comprises a track mechanism, a drill hole mechanism and a controller, the drill hole mechanism is arranged on the track mechanism and moves along the track mechanism, the drill hole mechanism comprises a annular track part, a radial track part, a drill part and asupporting part, the two ends of the radial track part are located on the annular track part and rotates along the annular track part in a circumferential direction, the drill part is arranged on theradial track part and moves along the radial track part in a straight line, the supporting part is located on the outer side of the annular track part and used for fixing the whole drill hole mechanism, and the controller is respectively connected with the annular track part, the radial track part, the drill part and the supporting part. According to the drill hole arrangement device, the structure design is scientific and reasonable, the degree of automation is high, the problem that by a traditional mode, drilling in the full cross section of a model experimental tunnel is difficult is solved, the precision and the efficiency of drilling are high, the coverage of the full cross section of the model experiment and drilling at any position by the drill hole mechanism can be achieved, thedevice is suitable for experimental models with various specifications.

Description

technical field [0001] The invention relates to a miniature full-section drilling arrangement device for model tests and an application thereof, belonging to the technical field of tunnel excavation test devices. Background technique [0002] Because the tunnel drilling and blasting method has the obvious advantages of economy, high efficiency and strong geological adaptability, it is still the most important and commonly used technical means in tunnel excavation construction in our country. There are about 10,000 tunnels and tunnels in my country, more than 90% of which are completed by tunnel blasting. It can be said that in the development history of tunnel construction in my country over the past century, a large chapter is the development history of tunnel blasting technology. However, various geological disasters are induced during the tunnel excavation process due to the disturbance of blasting and excavation, which brings great difficulties to the tunnel constructio...
