Description

Technical Field

[0001] This utility model relates to the field of hole enlargement devices, and in particular to a hole enlarger for geological exploration. Background Technology

[0002] Geological exploration is an investigation and research activity that involves exploring and detecting geology through various means and methods, determining suitable bearing strata, determining the foundation type based on the bearing capacity of the bearing strata, and calculating foundation parameters. During the geological exploration process, it is sometimes necessary to use a borehole enlarger to facilitate sampling by experimental personnel.

[0003] Existing borehole reamers for geological exploration generally do not have the feature of being replaceable. During use, it is impossible to change the size of the reamer to the required size, and the diameter of the borehole cannot be adjusted during the reaming process.

[0004] Therefore, those skilled in the art have provided a borehole reamer for geological exploration to solve the problems mentioned in the background art. Utility Model Content

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1-5 This utility model provides an embodiment of a borehole expander for geological exploration, comprising a support plate 1, a rotating column 2 rotatably disposed inside the support plate 1, a first connecting plate 3 fixedly disposed at the bottom end of the rotating column 2, a plurality of bolts 4 disposed inside the first connecting plate 3, nuts 5 threadedly connected to the outer sides of the plurality of bolts 4, a second connecting plate 6 disposed outside the plurality of bolts 4, a first motor 7 fixedly disposed at the inner top of the rotating column 2, and a limit connecting column 8 fixedly disposed at the output end of the first motor 7. The first connecting plate 3 and the second connecting plate 6 can be fixed and disassembled using the bolts 4 and nuts 5, thereby allowing the borehole expander to be disassembled and easily replaced.

[0035] Multiple fixing plates 9 are fixedly installed at the bottom of the second connecting plate 6, and drill bits 10 are fixedly installed at the bottom of the multiple fixing plates 9. The drill bits 10 can be fixed by connecting the fixing plates 9 with the connecting plate, which also facilitates the installation of threaded rods 11. Threaded rods 11 are provided on the outer side of the limiting connecting post 8, and threaded blocks 12 are threadedly connected to the outer side of the threaded rods 11. The diameter of the scraper 17 can be adjusted by using the threaded rods 11 in conjunction with the threaded blocks 12, which can be adjusted as needed. Telescopic rods 13 are fixedly installed around the outer edge of the threaded blocks 12, and connecting blocks 14 are fixedly installed at one end of each telescopic rod 13. The scraper 17 can be fixed by using the telescopic rods 13 in conjunction with the connecting blocks 14, which restricts the position of the scraper 17 during use and prevents it from being unable to be adjusted normally. Multiple... A fixing block 15 is used at the top of the drill bit 10 to fix the scraper 17, ensuring that the scraper 17 can be adjusted normally. Limiting rods 16 are fixedly installed on the inner side of the fixing blocks 15 and the inner side of the connecting blocks 14. Limiting rods 16 are installed inside the fixing blocks 15 and the connecting blocks 14, so that the scraper 17 can be easily adjusted. The scraper 17 is rotatably installed on the outer side of the multiple limiting rods 16. Installing the scraper 17 can enlarge the hole at the drilling position. A cover 18 is fixedly installed at the top of the support plate 1. A second motor 19 is fixedly installed at the top inner side of the cover 18. A connecting rod 20 is fixedly installed at the output end of the second motor 19. The second motor 19 is installed in conjunction with the connecting rod 20 to drive the rotating column 2 to rotate, so that the hole enlarging device can rotate normally.

[0036] Working principle: In use, the second connecting plate 6 is first fixed to the bottom end of the first connecting plate 3 using bolts 4 and nuts 5. When installing the second connecting plate 6, the limiting connecting post 8 and the threaded rod 11 must also be installed together so that the first motor 7 can drive the threaded rod 11 to rotate. Starting the first motor 7 and rotating the threaded rod 11 allows the threaded block 12 to move up and down on the threaded rod 11. When the threaded block 12 is adjusted up and down, it adjusts the opening position of the scraper 17. When the threaded block 12 is adjusted downwards, the scraper 17 opens outwards, thereby pulling the extension... The telescopic rod 13 extends outward, and when the threaded block 12 is adjusted upward, the scraper 17 retracts inward, which causes the telescopic rod 13 to retract. When adjusting the position of the scraper 17, the limiting rod 16 limits the scraper 17 to prevent it from falling off during adjustment. Then, the second motor 19 can be used to drive the connecting rod 20 to rotate, which in turn drives the rotating column 2 to rotate, allowing the device to rotate and drill holes in the soil. During use, the control device can also be used to control the first motor 7 to adjust the unfolding diameter of the scraper 17, thereby adjusting the size of the hole enlarger.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
