Description

Technical Field

[0001] The utility model relates to the technical field of positioning poles, in particular to a positioning pole based on geological surveying and mapping. Background Art

[0002] Geological surveying and mapping is a comprehensive work that uses knowledge from multiple disciplines such as surveying and mapping, geology, etc., through field measurement, data collection, analysis and processing, to record and draw detailed information on the landforms, geological structures, rock distribution, mineral resources, etc. on the earth's surface, form geological maps and related data, and provide basic information and scientific basis for geological research, mineral exploration, engineering construction, environmental protection, etc.

[0003] The positioning pole of geological surveying is a tool used for field measurement and positioning. Its main function is to serve as a reference to help surveyors conduct accurate measurements and collect terrain data. In geological surveying, the height and terrain conditions of the measuring points vary greatly. The multi-section telescopic positioning pole can adjust the height according to actual needs to ensure that the pole can adapt to different measurement environments and height requirements.

[0004] In geological surveying, the height adjustment of the positioning pole is usually divided into two stages: rapid extension and slow fine adjustment. Rapid extension can quickly put the pole on the ground to improve surveying efficiency, while slow fine adjustment ensures the accuracy of the pole height, thereby ensuring the accuracy of the measuring point. However, the method of adjusting the height of the positioning pole through a motor drive structure in the prior art has some disadvantages. First, the motor drive structure will increase the overall weight of the positioning pole, which not only increases the difficulty of carrying and transportation, but also affects its operational convenience in complex terrain. Secondly, the motor drive requires power support, and power supply limitations may reduce the continuity of the work, especially in field operations, where the power supply may be insufficient, affecting the continuous progress of the surveying work. Although the motor drive adjustment method can improve the adjustment efficiency and accuracy, the weight increase and power supply limitation problems it brings cannot be ignored. Therefore, a positioning pole based on geological surveying is proposed to address the above problems. Utility Model Content

[0035] As a further implementation of the present scheme, the fixing assembly 3 includes a first turning handle 31, the rear end of the first turning handle 31 is fixedly connected with a screw rod 32 and an internal threaded barrel 33, the outer side of the screw rod 32 is spirally connected to the inner side of the limiting telescopic rod 35, the rear end of the limiting telescopic rod 35 is fixedly connected to the front end of the toothed plate 34, the screw 32 is rotatably connected to the inner side of the limiting shaft hole 26 opened in the mounting seat 21, the rear end of the toothed plate 34 is meshed with the front end of the rack 54, and the front end of the limiting telescopic rod 35 is fixedly connected to the inner side of the mounting seat 21. Through the above arrangement, the distance between the upper benchmark shell 23 and the lower benchmark shell 51 can be fixed by the fixing assembly 3, and the effect of positioning the height of the geological surveying and mapping equipment 1 can be achieved at the same time;

[0036] As a further implementation of the present invention, the folding channel 22 passes through the upper and lower ends of the mounting seat 21, the placement groove 24 passes through the upper end of the upper marker rod shell 23, the folding channel 22 is connected to the placement groove 24, the placement groove 24 is opened in a cylindrical shape, the fan-shaped plate 42 is in a fan-shaped shape, the air-through plate 44 is opened on the inner side close to the shaft column 43, the outer side of the shaft column 43 is fixedly connected to the limited position rotating ring, the bottom end of the shaft column 43 is fitted with the top end of the protruding column 62, through the above arrangement, it is convenient for the air inside the placement groove 24 to circulate from the inside of the tapered hole 45, and the movement speed between the upper marker rod shell 23 and the lower marker rod shell 51 can be controlled by using the circulation speed of the gas;

[0037] As a further implementation of this scheme, the conical hole 45 passes through the inner side of the air-passing disk 44 from top to bottom, the opening shape of the conical hole 45 is composed of a cone and a cylinder, the inner side of the inner hollow plate 46 is a hollow structure, the bottom end of the inner hollow plate 46 is flush with the bottom end of the air-passing disk 44, the top end of the spring 47 is fixedly connected to the bottom end of the rubber cone 61, the outer side of the rubber cone 61 is fitted with the inner side of the upper end of the conical hole 45, the number of the blocking components 6 is set to be multiple, the shape of the rubber cone 61 is a cone, and the convex column 62 is embedded and installed inside the annular frame 66 The front and rear ends of the annular frame 66 are fixed with built-in protrusions 67, the front and rear ends of the protruding column 62 are provided with guide rail grooves 63, and the protruding column 62 protrudes from the upper end of the annular frame 66. Through the above arrangement, when operating the air flow adjustment component 4, the blocking component 6 can be moved or moved out of the inside of the tapered hole 45. Through the design of multiple blocking components 6, the descending speed of the geological surveying and mapping equipment 1 and the first benchmark component 2 under the action of gravity can be controlled, so as to accurately control the height of the geological surveying and mapping equipment 1;

[0038] As a further implementation scheme of the present scheme, the position of the lower benchmark rod shell 51 close to the embedding groove 53 slides on the inner side of the anti-rotation groove 27 opened in the upper benchmark rod shell 23, the weight reduction groove 52 runs through the upper end of the lower benchmark rod shell 51, the weight reduction groove 52 is connected with the placement groove 24, the outer side of the rubber ring 55 is fitted with the inner side of the placement groove 24 opened in the upper benchmark rod shell 23, and the position of the lower benchmark rod shell 51 close to the rubber ring 55 is at the upper end of the limiting plate 25. Through the above arrangement, the second benchmark rod assembly 5 is embedded and installed inside the first benchmark rod assembly 2, and the length between the first benchmark rod assembly 2 and the second benchmark rod assembly 5 can be adjusted. At the same time, the interiors of the first benchmark rod assembly 2 and the second benchmark rod assembly 5 are both hollowed out, which can greatly reduce the overall weight of the equipment and facilitate carrying.

[0039] The second turning handle 41 is rotated to drive the fan-shaped plate 42 and the shaft column 43 to rotate. The shaft column 43 is rotated and connected to the inner side of the gas vent plate 44, which can prevent the shaft column 43 from being separated from the gas vent plate 44, so that the fan-shaped plate 42 and the plurality of protrusions 62 are separated. Under the action of the elastic force of the spring 47, the rubber cone 61 and the protrusion 62 are pushed upward, and the protrusion 62 slides on the inner side of the annular frame 66. At the same time, the protrusion 62 slides on the outer side of the built-in protrusion 67 through the guide rail groove 63, which not only limits the moving distance of the protrusion 62, but also prevents the protrusion 62 from twisting inside the annular frame 66. At this time, the middle end position of the groove 64 is aligned with the bottom end of the second turning handle 41. At this time, the plurality of tapered holes 45 are connected to the folding channel 22 through the extension tube 48. When adjusting the distance between the second benchmark assembly 5 and the first benchmark assembly 2, the resistance is small. One hand holds the upper benchmark shell 23, and the other hand holds the lower benchmark shell 51 close to the The upper and lower mark rod shells 23 and the lower mark rod shells 51 are pulled in opposite directions. At this time, the outer side of the lower mark rod shell 51 slides inside the anti-rotation groove 27 and the placement groove 24. The opening shape of the embedding groove 53 and the opening shape design of the anti-rotation groove 27 can prevent the lower mark rod shell 51 from twisting inside the upper mark rod shell 23. The rubber ring 55 plays a sealing role between the lower mark rod shell 51 and the upper mark rod shell 23. After the head of the lower mark rod shell 51, that is, the part with a larger diameter, is fitted with the top of the limiting plate 25, the limiting plate 25 plays a role in limiting the extended distance between the lower mark rod shell 51 and the upper mark rod shell 23. At the same time, when the lower mark rod shell 51 is away from the placement groove 24, the external air will enter the placement groove 24 from the tapered hole 45, the extension tube 48 and the folding channel 22, so as to achieve the effect of quickly extending the distance between the first mark rod assembly 2 and the second mark rod assembly 5.

[0040] When the distance between the lower pole shell 51 and the upper pole shell 23 is slowly and finely adjusted, the lower pole shell 51 is inserted into the soil, and both hands are freed at this time. Through the cooperation of the air vent adjustment component 4 and the blocking component 6, the descending speed of the first pole component 2 and the geological mapping equipment 1 under the action of gravity can be controlled. The second turning handle 41 is turned according to the above principle. When the sector plate 42 contacts the groove 64 opened by the boss 62, the shape of the groove 64 is a slope. Under the squeezing of the sector plate 42, the boss 62 will drive the rubber cone 61 to move downward, and the rubber cone 61 will block the conical hole 45. The fewer the number of conical holes 45 that can be ventilated, the faster the descending speed of the first pole component 2 and the geological mapping equipment 1 will be. Slow, on the contrary, the more the first benchmark assembly 2 and the geological mapping equipment 1 are, the faster the descent speed is. During the descent of the geological mapping equipment 1 and the first benchmark assembly 2, hold the first turning handle 31 with one hand. After the geological mapping equipment 1 slowly descends to the specified distance, turn the first turning handle 31 to drive the screw rod 32 to rotate. The screw rod 32 rotates the outer spirally connected limit telescopic rod 35 to move backward. At this time, the limit telescopic rod 35 is extended, and the limit telescopic rod 35 plays a role in limiting the movement of the tooth plate 34. The tooth plate 34 is engaged with the rack 54 to achieve the role of fixing the position between the lower benchmark shell 51 and the upper benchmark shell 23, thereby completing the fine adjustment effect of the height of the geological mapping equipment 1;

[0041] In summary, the working principle is that the device uses the resistance of gas flow to control the effect of rapid extension and slow fine adjustment between the first benchmark assembly 2 and the second benchmark assembly 5. This adjustment method does not require the use of power and drive equipment, which reduces the overall weight of the equipment. At the same time, this adjustment method does not require the use of power and is suitable for continuous operation in the field.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
