Description
Technical Field
[0001] This invention relates to the field of borehole exploration technology, and in particular to a handheld push-in borehole trajectory measurement probe for mining. Background Technology
[0002] The handheld push-in borehole trajectory measurement probe is a portable measuring device that obtains trajectory data in real time or after the fact by manually pushing the tube into the borehole. It is widely used in scenarios such as coal mine gas extraction, geological exploration, and building pile foundation testing. Its core advantages are that it does not require external power equipment, is flexible in operation, and has controllable costs.
[0003] For example, Chinese Patent Publication No. CN211924150U discloses a handheld push-in borehole trajectory measuring probe for mining, comprising a tube body and a limiting strip. A fixing sleeve is provided in the middle of the tube body, and a support panel is mounted above the fixing sleeve. The limiting strip is located at both ends above the support panel, and a display screen is movably mounted above the limiting strip. The central axis of the tube body coincides with the central axis of the fixing sleeve, preventing cracks from appearing between the fixing sleeve and the tube body during use, thus improving the service life of the internal parts. The support panel and the fixing sleeve are an integral structure, ensuring that the connection strength between the support panel and the fixing sleeve does not decrease and preventing the support panel from detaching from the fixing sleeve. The display screen and the limiting strip are movably connected, allowing the user to select different sized display screens according to the usage environment.
[0004] In existing technologies, the tube body and end cap are mostly assembled using threads. However, when using the probe, the end cap needs to be removed to open the detection module, and then the end cap needs to be screwed back on to ensure a seal. The removal and screwing process requires turning the end cap multiple times due to the thread design, making the overall operation cumbersome and inefficient, and thus limiting its application.
[0005] Therefore, it is necessary to provide a handheld push-in borehole trajectory measurement probe for mining to solve the above-mentioned technical problems. Summary of the Invention
[0006] The purpose of this invention is to provide a handheld push-in borehole trajectory measurement probe for mining, so as to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, a handheld push-in borehole trajectory measurement probe for mining is designed, which eliminates the need for rotating the end cap multiple times along the pipe body and can effectively improve the assembly efficiency of the end cap and the pipe body.
[0008] Based on the above ideas, the present invention provides the following technical solution: a handheld push-in borehole trajectory measurement probe for mining, comprising a tube body, a handheld base and an end cap, wherein a detection module for trajectory measurement is provided on the tube body, and a sealing ring is fitted on the outer surface of the tube body and the side near the end cap, and a locking assembly is provided between the tube body and the end cap; the locking assembly enables quick assembly and disassembly of the tube body and the end cap, and the end cap can protect the detection module after being assembled relative to the tube body.
[0009] As a further aspect of the present invention: the locking assembly includes a guide groove formed on the outer surface of the tube body and an insert fixedly installed on the inner wall of the end cap. The size of the insert is adapted to the guide groove, and a first spring is fixedly installed inside the end cap.
[0010] As a further aspect of the present invention: the guide groove is designed in an L-shape and is divided into a horizontal part and a vertical part. The horizontal part is arranged along the axial direction of the tube body, and the vertical part is arranged along the circumferential direction of the tube body. The vertical part is located on the side of the horizontal part away from the end cap.
[0011] As a further aspect of the present invention: the inside of the tube body is provided with a limiting component extending into the guide groove, the limiting component corresponds to the junction of the horizontal part and the vertical part, and the surface of the insert is provided with a groove adapted to the limiting component; when the insert moves to the limit position along the horizontal part, the groove on the insert engages with the limiting component.
[0012] As a further aspect of the present invention: the limiting component includes a slider slidably mounted on the tube body, a second spring being fixedly mounted between the slider and the tube body, the slider sliding along the circumferential direction of the tube body and adapting to the groove.
[0013] As a further aspect of the present invention: the second spring is designed to be inclined; when the second spring is inclined to the junction of the horizontal portion and the vertical portion, the slider is limited to the junction of the horizontal portion and the vertical portion; when the second spring is inclined to the side of the vertical portion away from the horizontal portion, the slider is limited to the side of the vertical portion away from the horizontal portion.
[0014] As a further aspect of the present invention: the number of sealing rings is several, and all of them adopt a hollow elastic design.
[0015] As a further aspect of the present invention: the tube body is provided with an adjustment assembly that is connected to a plurality of sealing rings and fixedly connected to the slider; when the slider is located at the junction of the horizontal and vertical portions, the slider adjusts the two sealing rings to be in a de-aired state through the adjustment assembly; when the slider is located on the side of the vertical portion away from the horizontal portion, the slider adjusts the two sealing rings to be in an inflated state through the adjustment assembly.
[0016] As a further aspect of the present invention: the adjustment assembly includes a connecting rod fixedly connected to the slider, an annular cavity opened in the tube body, and a flow channel communicating with the annular cavity. The flow channel is connected to several sealing rings to form airflow. A plug driven by the connecting rod is slidably installed inside the annular cavity.
[0017] As a further aspect of the present invention: the annular cavity causes the movement trajectory of the plug to coincide with the movement trajectory of the slider; when the slider moves, the plug moves along the annular cavity through the connecting rod, thereby enabling several sealing rings to complete inflation / deflation.
[0018] Compared with the prior art, the beneficial effects of the present invention are: through the cooperation between the tube body, end cap and locking assembly, the end cap and tube body can be quickly assembled, and the relative positioning between the tube body and end cap can be achieved, thereby enabling the quick assembly and disassembly of the tube body and end cap, effectively improving the overall work efficiency.
[0019] The overall structure is simple and easy to operate. There is no need to rotate the end cap multiple times along the tube body. Simply put the end cap on the tube body and rotate it a small distance. This can effectively improve the efficiency of disassembly and assembly between the tube body and the end cap, and ensure the limiting and locking effect between the tube body and the end cap. It can also ensure the long-term stable use of the subsequent detection module, making it more practical. Attached Figure Description

[0032] Example 1:
[0033] Please see Figures 1 to 5 This invention provides a handheld push-in borehole trajectory measuring probe for mining, mainly used to achieve quick assembly and disassembly of the probe body 1 and end cap 2 without rotating the end cap 2 multiple times along the probe body 1. Specifically, it includes a probe body 1, a handheld base adapted to the probe body 1, and an end cap 2 adapted to the probe body 1, such as... Figure 1 As shown, the handheld base (not shown in the figure) is assembled with the left end of the tube body 1, which can realize the manual pushing of the tube body 1; the tube body 1 is provided with a detection module 3 for trajectory measurement. When the end cap 2 is engaged with the right end of the tube body 1, the detection module 3 can be effectively protected, avoiding direct contact with the complex environment inside the hole and affecting the service life of the detection module 3. When the end cap 2 is separated from the right end of the tube body 1, the detection module 3 can be quickly switched on and off.
[0034] Furthermore, such as Figure 1 As shown, a locking assembly 4 is provided between the tube body 1 and the end cap 2. The locking assembly 4 enables quick assembly and disassembly of the tube body 1 and the end cap 2, and ensures a locking effect between the tube body 1 and the end cap 2, thereby improving the overall assembly efficiency. In addition, a sealing ring 5 is also fitted on the outer surface of the tube body 1 to improve the sealing performance of the tube body 1 and the end cap 2 after assembly, resist the high dust and humid environment inside the hole, and ensure the effectiveness of the detection module 3.
[0035] In the above structure, such as Figure 2 As shown, there are two sealing rings 5. The sealing ring 5 near the end cover 2 (i.e., the right sealing ring 5) is a nitrile rubber O-ring, and the other sealing ring 5 is a polytetrafluoroethylene O-ring. The double mechanical seal enables the protection level to reach IP67, effectively reducing the failure of the detection module 3.
[0036] It should be noted that in this embodiment, the materials corresponding to the tube body 1, end cap 2, handheld base, detection module 3, and two sealing rings 5 are all existing mature technologies, and will not be described in detail here.
[0037] Reference Figure 2 and Figure 3 In this embodiment, preferably, the locking assembly 4 includes a guide groove 401 formed on the outer surface of the tube body 1 and an insert 402 fixedly installed on the inner wall of the end cap 2. The size of the insert 402 is adapted to the guide groove 401, and the guide groove 401 is generally L-shaped. When the end cap 2 is sleeved onto the tube body 1, the insert 402 can automatically insert into the guide groove 401 and move along the axial direction of the tube body 1. When it moves to the limit position along the axial direction of the tube body 1, rotating the end cap 2 can drive the insert 402 to move along the circumferential direction of the tube body 1.
[0038] Specifically, such as Figure 2 As shown, the L-shape of the guide groove 401 is divided into a horizontal part and a vertical part. The horizontal part is arranged along the axial direction of the tube body 1, and the vertical part is arranged along the circumferential direction of the tube body 1. Furthermore, a first spring 403 is fixedly installed inside the end cap 2. When the insert 402 moves to its limit position along the horizontal part, the first spring 403 is in a compressed state. Subsequently, when the insert 402 moves along the vertical part, the first spring 403 can apply a force to the insert 402 along the horizontal part, thereby improving the limiting effect between the end cap 2 and the tube body 1.
[0039] Furthermore, such as Figure 3 As shown, the tube body 1 has a cavity 6 inside that communicates with the vertical portion of the guide groove 401. A limiting component 7 extending into the guide groove 401 is disposed inside the cavity 6. The limiting component 7 corresponds to the junction of the L-shaped guide groove 401, that is, the junction of the horizontal and vertical portions. A groove (not shown in the figure) adapted to the limiting component 7 is formed on the surface of the insert 402. When the insert 402 moves to its limit position along the horizontal portion, the groove of the insert 402 engages with the limiting component 7. When the insert 402 moves along the vertical portion, the groove drives the limiting component 7 to slide along the cavity 6. At this time, the limiting component 7 further limits the position of the insert 402 after movement, thereby further improving the limiting effect between the end cap 2 and the tube body 1.
[0040] Reference Figure 4 and Figure 5In this embodiment, preferably, the limiting component 7 includes a slider 701 slidably installed in the cavity 6. The slider 701 slides along the circumferential direction of the tube 1 and is adapted to the groove. A second spring 702 is fixedly installed between the slider 701 and the cavity 6. The second spring 702 is designed with an inclination based on the cavity 6, so that the slider 701 can be limited to one side edge of the cavity 6. The slider 701 corresponds to the junction of the horizontal and vertical portions and is used to engage with the groove of the insert 402.
[0041] Specifically, such as Figure 5 As shown, when the second spring 702 is tilted to the upper right, the slider 701 is limited to the upper side of the cavity 6 and located at the junction of the horizontal and vertical portions. When the second spring 702 is tilted to the lower right, the slider 701 is limited to the lower side of the cavity 6 and located on the side where the vertical portion is located in the horizontal portion. At this time, the slider 701 also has the tendency to continue sliding down the cavity 6.
[0042] In use, first open the detection module 3 and then put the end cap 2 into the tube body 1, so that the insert 402 moves along the horizontal part of the guide groove 401 until the insert 402 engages with the slider 701. Then rotate the end cap 2 to drive the insert 402 to move along the vertical part. When the insert 402 moves to the side of the vertical part away from the horizontal part, the groove and the slider 701 cause the tilt direction of the second spring 702 to change from pointing to the junction of the horizontal and vertical parts to pointing to the side of the vertical part away from the horizontal part. At this time, in conjunction with the compression of the first spring 403 after the end cap 2 is put on, the position of the insert 402 in the vertical part can be effectively ensured to be stable, thereby ensuring the limiting effect between the end cap 2 and the tube body 1.
[0043] In summary, through the cooperation of structures such as the insert 402, the guide groove 401, and the first spring 403, the end cap 2 and the tube body 1 can be quickly assembled, and the relative positioning between the tube body 1 and the end cap 2 can also be achieved, thereby enabling the quick assembly and disassembly of the tube body 1 and the end cap 2, effectively improving the overall work efficiency.
[0044] By cooperating with the slider 701, the insert 402, and the second spring 702, the sliding process of the insert 402 along the guide groove 401 switches the tilt direction of the second spring 702, so that the insert 402 is further limited in the vertical part after it moves, which can further improve the limiting effect between the tube body 1 and the end cap 2.
[0045] The overall structure is simple and easy to operate. There is no need to rotate the end cap 2 multiple times along the tube body 1. It only needs to correspond to the vertical part of the guide groove 401. This can effectively improve the disassembly and assembly efficiency and work efficiency between the tube body 1 and the end cap 2. Moreover, the limiting and locking effect between the tube body 1 and the end cap 2 is better, which can ensure the long-term stable use of the subsequent detection module 3 and make it more practical.
[0046] Example 2:
[0047] Please see Figures 1 to 8 Based on Embodiment 1, considering that the two sealing rings 5 will protrude relative to the outer surface of the tube body 1 in order to ensure sealing, the resistance between the end cap 2 and the tube body 1 will be large when the end cap 2 is assembled to the tube body 1, which will cause a burden on the workers and affect the quick assembly and disassembly between the tube body 1 and the end cap 2.
[0048] Therefore, the sealing ring 5 is modified accordingly: the sealing ring 5 adopts a hollow elastic design. When air is filled into the sealing ring 5, the sealing ring 5 can expand and protrude relative to the outer surface of the tube body 1, thereby playing an effective sealing role. When the gas in the sealing ring 5 is drawn out, the sealing ring 5 can shrink to the outer surface of the tube body 1. At this time, the end cap 2 can be easily removed from the tube body 1.
[0049] Furthermore, the tube body 1 is provided with an adjustment component 8 that is connected to both sealing rings 5 and fixedly connected to the slider 701. When the slider 701 is located at the junction of the horizontal and vertical parts, the slider 701 adjusts the two sealing rings 5 to be in a vacuum state through the adjustment component 8. At this time, the sealing rings 5 are relatively contracted and the end cap 2 can be easily put onto the tube body 1. When the slider 701 is located on the side of the vertical part away from the horizontal part, the slider 701 adjusts the two sealing rings 5 to be in an inflated state through the adjustment component 8. At this time, the sealing rings 5 are relatively expanded to ensure an effective seal between the end cap 2 and the tube body 1.
[0050] Furthermore, two slots 201 corresponding to the two sealing rings 5 can be opened on the inner wall of the end cap 2, and annular grooves 101 for the two sealing rings 5 can be opened on the outer surface of the tube body 1. When the sealing rings 5 contract relatively, they are hidden in the annular grooves 101, and when the sealing rings 5 expand relatively, they protrude from the annular grooves 101 and are engaged in the slots 201.
[0051] Reference Figures 6 to 8 In this embodiment, preferably, the adjusting component 8 includes a connecting rod 802 fixedly connected to the slider 701, an annular cavity 803 opened in the tube 1, and a flow channel 804 connected to the annular cavity 803. The flow channel 804 is connected to both sealing rings 5 to form airflow. A plug 801 driven by the connecting rod 802 is slidably installed inside the annular cavity 803. When the slider 701 moves, it can drive the connecting rod 802 to move synchronously, thereby causing the plug 801 to move along the annular cavity 803 to perform the inflation / deflation process, thereby realizing the relative contraction / expansion of the two sealing rings 5.
[0052] Among them, such as Figure 7As shown, the design of the annular cavity 803 ensures that the movement trajectory of the plug 801 coincides with the movement trajectory of the connecting rod 802 and the slider 701, thereby ensuring the stable movement of the plug 801 within the annular cavity 803 and thus achieving stable inflation / deflation processes.
[0053] In use, the end cap 2 and the tube body 1 can be quickly assembled through the structure of the insert 402, guide groove 401, slider 701 and first spring 403, and the effective limiting between the tube body 1 and the end cap 2 can be achieved. The working process and effect of this part are the same as in embodiment one, and will not be repeated here. The difference is that when the slider 701 is located at the junction of the horizontal and vertical parts, the slider 701 drives the plug 801 to be on the side of the annular cavity 803 away from the flow channel 804 through the connecting rod 802. At this time, the two sealing rings 5 are in a relatively contracted state due to air extraction. At this time, the end cap 2 can be quickly and easily put on the tube body 1, and the slot 201 and the annular groove 101 form a one-to-one correspondence. When the rotating end cap 2 drives the slider 701 to move to the side of the vertical part away from the horizontal part, the slider 701 drives the plug 801 to move along the annular cavity 803 through the connecting rod 802, so that the two sealing rings 5 are inflated and become relatively expanded. At this time, the sealing rings 5 are respectively attached to the annular groove 101 and the slot 201, which can ensure the sealing effect between the end cap 2 and the tube body 1.
[0054] Compared to Embodiment 1, the sealing ring 5, slider 701, plug 801 and annular cavity 803 can switch between a relatively contracted state and a relatively expanded state through the cooperation of the sealing ring 5, slider 701, plug 801 and annular cavity 803. When relatively contracted, the end cap 2 can be quickly and easily put on the tube body 1. When relatively expanded, the sealing effect between the end cap 2 and the tube body 1 can be guaranteed.
[0055] The relative expansion of the sealing ring 5 allows it to fit into the annular groove 101 and the slot 201 respectively, which can further improve the sealing effect between the end cap 2 and the tube body 1. At the same time, it also has a beneficial effect on limiting the end cap 2 relative to the tube body 1, which can further ensure the locking state of the end cap 2 relative to the tube body 1.
[0056] The overall design utilizes the movement of slider 701 along cavity 6, while the inclined design of second spring 702 serves to limit the position of slider 701 on the one hand, and to limit the relative contraction and expansion of sealing ring 5 on the other hand, making the component more functional.
[0057] Example 3:
[0058] Please see Figures 1 to 10 Based on Example 2, considering that the rotation distance of the end cap 2 along the circumferential direction of the tube body 1 will not be large, and that the two sealing rings 5 need sufficient inflation / deflation to form a relative expansion / contraction process.
[0059] Therefore, the connecting rod 802 is improved: the connecting rod 802 now includes an arc-shaped rod 8021 fixedly connected to the slider 701, a first arc-shaped rack 8022 fixedly installed in the annular cavity 803, and a second arc-shaped rack 8023 fixedly connected to the plug 801. The end of the arc-shaped rod 8021 is rotatably mounted with a gear 8024 that is both drively connected to the first arc-shaped rack 8022 and the second arc-shaped rack 8023.
[0060] In the above structure, such as Figure 10 As shown, the first arc-shaped rack 8022 and the second arc-shaped rack 8023 are arranged symmetrically and alternately based on the gear 8024. When the arc-shaped rod 8021 moves synchronously with the slider 701, it can drive the gear 8024 to move along the first arc-shaped rack 8022. At this time, the gear 8024 can also rotate, causing the second arc-shaped rack 8023 to move along the annular cavity 803, thereby driving the plug 801 to move synchronously. At this time, the first arc-shaped rack 8022, the gear 8024, and the second arc-shaped rack 8023 form a rack-and-pinion structure, which makes the travel of the second arc-shaped rack 8023 greater than the travel of the gear 8024, the arc-shaped rod 8021, and the slider 701, ultimately ensuring that the two sealing rings 5 have sufficient inflation / deflation. It can be understood that the travel of the second arc-shaped rack 8023 is equal to the travel of the gear 8024 plus the rotational travel of the gear 8024.
[0061] In use, the end cap 2 and the tube body 1 can be quickly assembled through the structure of the insert 402, guide groove 401 and slider 701, and the tube body 1 and the end cap 2 can be effectively limited. Through the structure of the sealing ring 5, slider 701, plug 801 and annular cavity 803, the sealing ring 5 can switch between a relatively contracted state and a relatively expanded state, which facilitates the quick disassembly and assembly of the end cap 2 and ensures the sealing effect. The working process and effect of this part are the same as in embodiment 2, and will not be repeated here. The difference lies in the following: when the rotating end cap 2 moves the slider 701 to the side of the vertical part away from the horizontal part, the slider 701 drives the gear 8024 to move synchronously through the arc rod 8021. The gear 8024 drives the second arc rack 8023 and the plug 801 to move a further distance through the first arc rack 8022, thereby allowing the two sealing rings 5 to be sufficiently inflated to form a relative expansion. Of course, when the slider 701 is reset with the insert 402, the further movement of the plug 801 can also allow the two sealing rings 5 to be sufficiently deflated to form a relative contraction.
[0062] Compared to Embodiment 2, the combination of the slider 701, the arc-shaped rod 8021, the gear 8024, and the first arc-shaped rack 8022 forms a rack-and-pinion structure, which increases the travel of the plug 801. This allows the two sealing rings 5 to receive sufficient inflation and deflation. Without requiring the end cap 2 to rotate a large distance along the tube 1, it ensures the stable formation of relative contraction and relative expansion states, thereby guaranteeing quick assembly and disassembly of the end cap 2 and ensuring a good seal after assembly. The overall solution still utilizes the movement of the slider 701, and integrates the structure within the annular cavity 803, resulting in a clever design and better performance.
