Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering equipment, in particular to a drilling device for civil engineering detection. Background Art

[0002] Civil engineering is a general term for the science and technology of building various land engineering facilities. It refers to the materials and equipment used and the technical activities such as survey, design, construction, maintenance and repair carried out. In geological work, a wellbore with a small diameter and a certain depth drilled underground by a drilling rig is usually called a borehole. Borehole measurement is an important part of geophysical well logging technology, and plays an extremely important role in borehole quality inspection, borehole orientation, mineral resource assessment, well construction engineering, etc. The drilling device for civil engineering inspection refers to the device used to perform drilling inspection on the ground during civil engineering.

[0003] After searching, a vertical drilling detection device for construction engineering in the Chinese utility model patent with patent number CN219528997U includes: a support ring, an adjustment plate located above the support ring, and a detection rod located inside the support ring, an adjustment plate is arranged above the support ring, and a support adjustment mechanism is arranged between the support ring and the adjustment plate; the support adjustment mechanism includes a support sleeve and a support rod. In this vertical drilling detection device for construction engineering, the support ring is arranged above the drill hole through a support foot, the adjustment plate can be adjusted to a horizontal state on the support ring through the support adjustment mechanism, and the detection rod on the adjustment ball can be rotated on the adjustment plate through the adjustment ball under the action of gravity, so that the detection rod will be vertically downward , so that the detection rod can be twisted to move on the adjusting ball, so that the detection rod can drive the disc to probe into the borehole. When the vertical detection rod drives the disc to extend into the borehole without hindrance, it means that the borehole is in a vertical state, which is convenient for vertical detection. Although the device can realize that the vertical detection rod can drive the disc to extend into the borehole without hindrance for vertical detection, the device can only use the detection rod of a specified length to detect underground soil boreholes, and cannot use the split drill rod to splice drill rods of different lengths to detect deeper soil. Therefore, a civil engineering detection drilling device is proposed, which can use the split drill rod to splice drill rods of different lengths to detect deeper underground soil.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 In this embodiment, a drilling device for civil engineering inspection includes a workbench 1, a splitting mechanism 2 is arranged outside the workbench 1, and a placement box 3 is fixedly installed on the top of the workbench 1;

[0021] The splitting mechanism 2 includes a bracket 201, a threaded rod 1 202, a rotating disk 203, a threaded rod 204, a clamping column 205, a spring 206, a movable block 207 and a push plate 208. The bracket 201 is fixedly installed on the top of the workbench 1, the threaded rod 1 202 is arranged on the outside of the bracket 201, the rotating disk 203 is fixedly installed on the top of the threaded rod 1 202, the threaded rod 204 is arranged on the bottom of the threaded rod 1 202, the clamping column 205 is fixedly installed on the bottom of the threaded rod 204, the spring 206 is fixedly installed inside the clamping column 205, the movable block 207 is fixedly installed on the left side of the spring 206, and the push plate 208 is arranged on the left side of the movable block 207.

[0022] In the case implementation, a threaded hole is opened on the outside of the bracket 201, and the threaded hole is compatible with the threaded rod 1 202 and the threaded rod 204. By setting the threaded hole, the threaded rod 1 202 and the threaded rod 204 can be rotated synchronously, which is conducive to drilling downward.

[0023] In the case implementation, two limit blocks are fixedly installed on the outside of the clamping column 205, and a slot compatible with the clamping column 205 and the two limit blocks is opened inside the threaded rod 204. By setting the clamping column 205, the two limit blocks and the slot, the clamping column 205 can be installed in the slot and connected to the threaded rod 1 202 and the threaded rod 2 204, which is conducive to installing more threaded rods 1 202 and extending the drilling depth.

[0024] In the case implementation, further, a placement frame is fixedly installed on the outside of the placement box 3, and an insertion rod is arranged inside the placement frame. By arranging the placement frame and the insertion rod, the insertion rod needs to be used.

[0025] When implementing, follow these steps:

[0027] 2) Then the movable block 207 compresses the spring 206 to the right and enters the slot synchronously with the clamping column 205. Then the compressed spring 206 pushes the movable block 207 to the left and clamps it into the movable slot. The movable block 207 pushes the push plate 208 and the blocking column to the left to block the movable slot. The clamping column 205 cannot move up and down and is limited.

[0028] 3) Rotate the rotating disk 203 at the top to make the threaded rod 1 202 and the threaded rod 204 match the threaded holes on the bracket 201, and slowly drill downwards. The bottom detection device of the threaded rod 204 at the bottom performs detection at different heights;

[0029] 4) When a deeper drilling is required, the movable block 207 is pushed to the right by the insert block to return the movable block 207 to its original position, and then the clamping column 205 is pulled out, and more threaded rods 202 are installed according to the required drilling depth.

[0030] In summary, the drilling device for civil engineering inspection, by setting up a splitting mechanism 2, when drilling inspection is needed, the workbench 1 is placed on the ground where holes need to be drilled, and the clamping column 205 is clamped into the clamping slot at the top of the threaded rod 204, and by setting up a movable block 207, a spring 206 and a movable block 207, after the clamping column 205 enters the clamping slot, the movable block 207 is clamped to the left by the spring 206, and by setting up a rotating disk 203, a threaded rod 1 202, a threaded rod 204 and a threaded hole, the threaded rod 204 can be slowly drilled downward, and when deeper drilling is needed, the push plate 208 is pushed by a rod to return the movable block 207, and more threaded rods 1 202 are installed to lengthen the drilling depth. The splitting mechanism 2 can use a split drill rod, and by splicing drill rods of different lengths, the soil at a deeper level underground can be inspected.
