Description

Technical Field

[0001] This utility model relates to the field of exploration auxiliary equipment technology, and in particular to a vertical positioning mechanism for exploration drilling. Background Technology

[0002] Exploratory drilling is a technique used in engineering geological exploration to create boreholes using mechanical drilling and to collect undisturbed or disturbed soil samples using specialized samplers. Especially when using handheld drilling rigs, workers typically need to hold and manually support the rig as it moves downwards. A mini level must also be installed on the rig during operation to help monitor its levelness and ensure the drill rod is perpendicular to the ground.

[0003] In actual drilling operations, existing handheld drilling rigs require manual handling and rely on arm strength to move the rig downwards. The resulting swaying during drill rod rotation is difficult to overcome, making it impossible to ensure that the drill rod is drilled into the soil in a completely vertical position. This significantly reduces the stability of the drilling rig during use. Therefore, this application proposes an auxiliary vertical positioning mechanism for exploration drilling that can improve the stability of drilling rig operation. Utility Model Content

[0004] The purpose of this invention is to address the problem in the prior art where relying on the strength of the arm is insufficient to overcome drilling rig swaying, and to propose an auxiliary vertical positioning mechanism for exploration drilling that can improve the stability of drilling rig operation.

[0006] The telescopic rod is composed of a first hollow tube and a second hollow tube. The bottom end of the first hollow tube is fixed to the top of the support frame, and the top end of the second hollow tube is fixedly installed on the bottom of the support plate. The bottom end of the second hollow tube is inserted into the first hollow tube and movably connected to it. The first and second hollow tubes are equipped with buffer components inside.

[0009] Optionally, a rubber sleeve is fitted onto the outer wall of the solid rod, and the outer wall of the rubber sleeve is in close contact with the inner wall of the limiting slot. The solid rod, the limiting slot, and the rubber sleeve together form a buffer assembly.

[0010] Optionally, the connecting frame includes several collars, which are fixedly installed on the outer side wall of the matching first hollow tube. A connecting plate is fixedly installed between two adjacent collars, and a positioning screw is threaded onto the connecting plate. The drill rod limiting sleeve is engaged with the several positioning screws.

[0011] Optionally, the drill pipe limiting sleeve includes an outer sleeve, which is engaged with several positioning screws. An inner sleeve is provided on the inner side of the outer sleeve, and several steel balls are movably installed between the outer side wall of the inner sleeve and the inner side wall of the outer sleeve.

[0028] Example

[0029] like Figure 1 , Figure 2 and Figure 5 As shown, the present invention proposes an auxiliary vertical positioning mechanism for exploration drilling, comprising a support frame 1. A plurality of telescopic rods 2 are fixedly installed at the top of the support frame 1. Each telescopic rod 2 is composed of a first hollow tube 21 and a second hollow tube 22. The bottom end of the first hollow tube 21 is fixed to the support frame 1, and the second hollow tube 22 is movably inserted into a matching first hollow tube 21. A support plate 3 is fixedly installed at the top of the plurality of second hollow tubes 22. The support plate 3 is used to support and fix a handheld drilling rig. The aforementioned first hollow tube... The first hollow tube 21 and the second hollow tube 22 are equipped with a buffer assembly to prevent the support plate 3 and the drilling rig from falling rapidly and to improve the stability of the drilling rig when it moves downward. A connecting frame 4 is fixedly installed on the first hollow tube 21. A drill rod limiting sleeve 5 is engaged on the connecting frame 4 and located below the support plate 3. The drill rod limiting sleeve 5 adopts a bearing structure. When the drill rod passes through the inner ring of the drill rod limiting sleeve 5, it can not only limit the drill rod, but also not hinder the rotation of the drill rod, effectively reducing the shaking amplitude when the drill rod rotates.

[0030] like Figures 1-3 As shown, to improve the stability of the drilling rig during downward movement, a buffer assembly is installed inside the first hollow tube 21 and the second hollow tube 22. This buffer assembly consists of a solid rod 211, a limiting slot 221, and a rubber sleeve 212. Several solid rods 211 are fixedly installed inside the first hollow tube 21, and several limiting slots 221 are chiseled at one end of the second hollow tube 22 near the first hollow tube 21. The aforementioned solid rods 211 are inserted into matching limiting slots 221 and movably connected to them. Multiple rod-like structures are used as the first hollow tube 21 and the second hollow tube 22. The connector of the two hollow tubes 22 can improve the stability of the connection between the two; the rubber sleeve 212 is sleeved on the outer wall of the solid rod 211, and the outer wall of the rubber sleeve 212 is in close contact with the inner wall of the limiting slot 221. The rubber sleeve 212 can increase the friction between the solid rod 211 and the contact end face of the limiting slot 221. During the process of the second hollow tube 22 retracting into the first hollow tube 21, it can slow down its descent speed and prevent the drilling machine installed on the top of the support plate 3 from falling quickly, effectively improving the stability of the drilling machine when it moves down.

[0031] like Figure 4 As shown, in order to prevent the drill rod limiting sleeve 5 from obstructing the rotation of the drill rod, a bearing structure is used to form the drill rod limiting sleeve 5. The drill rod limiting sleeve 5 consists of an outer sleeve 51 and an inner sleeve 52. Several steel balls 55 are movably installed between the outer sleeve 51 and the inner sleeve 52 to ensure that the inner sleeve 52 can rotate inside the outer sleeve 51. When the drill rod passes through the inner sleeve 52, the rotation of the drill rod can drive the inner sleeve 52 to rotate, avoiding obstruction to the rotation of the drill rod. The inner sleeve 52 can limit the drill rod in the horizontal direction, effectively reducing the shaking amplitude of the drill rod.

[0032] Secondly, in order to improve the stability of the connection between the inner sleeve 52 and the outer sleeve 51, after the inner sleeve 52 is inserted into the inner side of the outer sleeve 51, a limiting ring 53 is welded on the outer side wall of the inner sleeve 52. At this time, the outer sleeve 51 is positioned between the two limiting rings 53, which can prevent the inner sleeve 52 from separating from the outer sleeve 51 and effectively improve the stability of the connection between the two.

[0033] like Figure 1 , Figure 4 and Figure 5As shown, to facilitate the assembly and disassembly of the drill pipe limiting sleeve 5, a collar 41 is fixedly installed on the outer wall of the first hollow tube 21. A connecting plate 42 is fixedly installed between each pair of adjacent collars 41. A positioning screw 43 is threaded onto the connecting plate 42. The collar 41, connecting plate 42, and positioning screw 43 together form the connecting frame 4. When installing the drill pipe limiting sleeve 5, first place the drill pipe limiting sleeve 5 in the middle position of the connecting frame 4, and rotate multiple positioning screws 43 to one side of the drill pipe limiting sleeve 5. When the end of the positioning screw 43 is inserted into the outer wall of the outer sleeve 51, a connecting plate 42 is fixedly installed between the collars 41 and the connecting plate 42. Once inside the screw limiting cylinder 54, multiple positioning screws 43 can be used to fix the drill rod limiting sleeve 5, ensuring that the drill rod limiting sleeve 5 can be stably installed on the connecting frame 4. When it is necessary to disassemble the drill rod limiting sleeve 5, the positioning screw 43 can be rotated to the side away from the drill rod limiting sleeve 5. After the end of the positioning screw 43 is pulled out from inside the screw limiting cylinder 54, the drill rod limiting sleeve 5 can be removed, effectively improving the convenience of disassembling and assembling the drill rod limiting sleeve 5. In actual use, the drill rod limiting sleeve 5 with a diameter that matches the diameter of the drill rod can be replaced, improving the adaptability of the positioning mechanism.

[0034] like Figure 1 and Figure 6 As shown, in order to improve the convenience of using the positioning mechanism, several casters 13 are rotatably installed at the bottom of the support frame 1, and a handrail 31 is fixedly installed on the outer side wall of the support plate 3. When the operator holds the handrail 31 and pushes the positioning mechanism, the positioning mechanism can be easily moved with the assistance of the casters 13.

[0035] Furthermore, several sleeves 11 are fixedly installed on the top of the aforementioned support frame 1, and insert rods 12 are movably inserted into the sleeves 11. When the positioning mechanism moves to the designated position, the bottom end of the insert rod 12 is inserted into the soil, thereby fixing the support frame 1 and ensuring that the positioning mechanism can be stably erected on the ground of the exploration area.

[0036] Secondly, the aforementioned support plate 3 has a circular opening 32. When the drilling rig is installed, after the drill rod passes through the circular opening 32, the drilling rig is fixedly assembled on the top of the support plate 3 to ensure that the bottom end of the drill rod can pass through the drill rod limiting sleeve 5. Several level mounting seats 33 are fixedly installed on the top of the support plate 3. The mini level is embedded and locked in the level mounting seat 33. During drilling operations, the workers can observe the mini level and make timely fine adjustments when the support plate 3 is not parallel to the ground, so as to ensure that the drill rod is perpendicular to the ground when drilling into the soil.

[0037] In this embodiment, the handheld drill is first placed on top of the support plate 3, and the drill rod passes through the circular opening 32. After the bottom end of the drill rod passes through the inner sleeve 52 of the drill rod limiting sleeve 5, the drill is fixed to the support plate 3 with bolts. During the process of the drill rotating the drill rod, the operator holds the handle 31 and moves the support plate 3 and the drill downward to ensure that the drill rod is rotating and drilling into the soil. During this process, the drill rod is horizontally limited by the drill rod limiting sleeve 5, which can reduce the sway of the drill rod. Since the inner sleeve 52 and the outer sleeve 51 are rotatably connected as one piece, the outer wall of the drill rod contacts the inner side wall of the inner sleeve 52. When the drill rod rotates, the inner sleeve 52 can rotate with it, so it will not hinder the rotation of the drill rod and ensure the rotation efficiency of the drill rod. As the support plate 3 and the drill move downward... During the process, the second hollow tube 22 retracts into the first hollow tube 21. At this time, the first hollow tube 21 forms a horizontal limit on the outside of the second hollow tube 22. Multiple solid rods 211 are connected to the limit slots 221. The multi-limit structure reduces the shaking amplitude when the second hollow tube 22 retracts into the first hollow tube 21. In addition, a rubber sleeve 212 is sleeved on the outer wall of the solid rod 211. The rubber sleeve 212 increases the friction between the solid rod 211 and the limit slots 221, which can prevent the support plate 3 and the drilling machine from falling quickly and improve the stability of the drilling machine when moving downward. Combined with the limit of the drill rod limit sleeve 5 on the rotating drill rod, it can solve the problem that the vibration generated during the use of the drilling machine is difficult to overcome by human arm strength, and effectively improve the stability of the drilling machine during use.

[0038] The above specific embodiments are merely several optional embodiments of this utility model.
