Description

Technical Field

[0001] This application relates to the field of geological exploration technology, specifically a geological exploration positioning device. Background Technology

[0002] Geological exploration is an indispensable foundational work in fields such as engineering construction, resource exploration, and environmental assessment. Its core task is to obtain original samples of underground rock and soil through drilling and sampling, and then analyze their physical and mechanical properties, stratigraphic structure, and composition. In this process, the stability of drilling and sampling equipment is the primary prerequisite for ensuring operational accuracy and safety. It is directly related to the accuracy of sampling point positioning, drilling verticality, and the quality of the samples obtained, and plays a decisive role in the reliability and validity of exploration data.

[0003] Currently, common geological exploration drilling equipment on the market typically consists of a base, a drive lifting mechanism, a power head, and drill rods and drill bits. During operation, the entire device is placed directly on the ground surface to carry out the work.

[0004] For example, patent CN209483339U discloses a high-precision engineering geological exploration positioning device. This patent uses a cylinder to drive a motor and a drill barrel to descend vertically. The motor drives the drill barrel to rotate, and the verticality is ensured by a two-point-one-line limiting bushing to complete the sampling operation.

[0005] However, in actual exploration work, the working environment is often very complex, especially in special sites with soft soil and extremely poor bearing capacity, such as tidal flats, swamps, sandy areas, and newly backfilled areas. The self-weight of the equipment and the violent vibrations, huge reverse torque and downward pressure generated during drilling can easily cause uneven settlement or overall slippage of the base, or even cause the equipment to overturn. This will not only cause serious deviations in the preset sampling point positions, resulting in sampling failure and data distortion, but may also damage expensive drilling tools and even cause safety accidents, threatening the personal safety of operators.

[0006] Therefore, it is necessary to provide a geological exploration and positioning device to solve the above problems.

[0007] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0033] like Figure 1 As shown, this application provides a geological exploration positioning device, which is mainly installed at the field geological exploration site to achieve accurate positioning and collection of soil samples. Specifically, the geological exploration positioning device includes a base 1 and a sampling mechanism 2 fixedly installed on the upper end of the base 1. The sampling mechanism 2 includes a gantry-shaped support 21 fixedly installed on the upper end of the base 1. In order to provide precise guidance for the lifting movement, two parallel guide rods 22 are vertically fixed between the support 21 and the base 1 on both sides.

[0034] Furthermore, a sliding plate 23 is slidably disposed on the guide rod 22, and a first motor 24 is fixedly installed on the upper end face of the sliding plate 23. The output shaft of the first motor 24 extends vertically downward through the sliding plate 23, and a sampling drill bit 25 for drilling soil samples is fixedly connected to its end via a coupling.

[0035] In order to carry out subsequent sampling operations, an electric cylinder 26 is fixedly installed on the top of the bracket 21. The output end of the electric cylinder 26 is fixedly connected to one side of the sliding plate 23. Thus, when the electric cylinder 26 is started, the extension or retraction of its output end will directly push or pull the sliding plate 23, thereby driving the first motor 24 and the sampling drill bit 25 to slide precisely up and down along the vertical trajectory defined by the guide rod 22, thereby completing the complete action of drilling, sampling and lifting recovery.

[0036] It should be noted that a through hole (not shown in the figure) is provided on the base 1 directly below the sampling drill bit 25. This through hole provides an unobstructed passage for the descent of the sampling drill bit 25, allowing it to descend vertically to contact and enter the ground for sampling operations.

[0037] To maintain stability when working on soft soil and prevent it from sinking or tilting, such as Figures 1-3 As shown, positioning mechanisms 3 are evenly distributed around the bottom of the base 1. Each positioning mechanism 3 includes a cylindrical fixing sleeve 30 fixedly installed at the lower end of the base 1, and a support frame 31 is fixedly installed inside the fixing sleeve 30. A second motor 32 is fixedly installed at the upper end of the support frame 31. The output end of the second motor 332 is vertically downward and a screw 33 is fixedly installed through the support frame 31. Thus, starting the second motor 32 can drive the screw 33 to perform forward and reverse rotation at the center position of the support frame 31.

[0038] Furthermore, at least three sets of operating rods 34 are hinged to the outer wall of the fixed sleeve 30, and a control disk 36 is connected to the screw 33 via threaded transmission. At least three sets of radially distributed support plates 35 are hinged to the outer edge of the control disk 36, and the other side of each support plate 35 is hinged to the middle position of the corresponding operating rod 34, so as to completely constrain all circumferential rotational degrees of freedom of the control disk 36, so that its motion trajectory is restricted to translation only along the axial direction of the screw 33. Thus, when the second motor 32 drives the screw 33 to rotate, the control disk 36 meshing with the screw 33 will generate displacement along the axial direction (i.e., the vertical direction) of the screw 33.

[0039] It should be noted that the bottom surface of the support plate is also provided with anti-slip texture to increase friction, so as to facilitate subsequent positioning operations.

[0040] When the control panel 36 is driven to move downward, it will simultaneously push down and outward all the support plates 35 that are hinged to it. Since the other end of the support plate 35 is connected to the fixed sleeve 30 through the operating rod 34, the support plate 35 is forced to unfold outward around its hinge point.

[0041] Finally, all support plates 35 will be fully extended and laid flat on the ground to increase the actual contact area between the device and the ground, effectively dispersing the pressure of the device on the ground and thus avoiding the risk of sinking in soft soil.

[0042] To enhance the anchoring effect and resist the huge vibrations and lateral forces generated during drilling, a positioning cone 37 is vertically fixed downward on the outer edge of the control panel 36, located between two adjacent support plates 35. The end of the positioning cone 37 is sharp, so that as the control panel 36 moves downward and the support plates 35 gradually unfold, these positioning cones 37 also move downward synchronously, and with their sharp points, they penetrate and deeply embed themselves in the soil, thereby providing extremely strong pull-out resistance and anti-rollover ability, achieving a stable effect during operation.

[0043] Once the equipment arrives at the soft survey site, the second motor 32 is started first, driving the control panel 36 of the positioning mechanism 3 to move down, simultaneously unfolding the support plate 35 and pressing it into the positioning cone 37 until the device is completely and stably supported and anchored. Then, the electric cylinder 26 and the first motor 24 are started to carry out precise and stable drilling and sampling operations. After the operation is completed, the second motor 32 is driven in reverse to retract the positioning mechanism for easy transfer.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
