Description

Technical Field

[0001] This application relates to the field of measurement equipment support technology, and in particular to a gyroscope orientation tripod. Background Technology

[0002] A gyro-orientation instrument is a measuring device that utilizes the gyro effect for high-precision north-finding and azimuth transfer. It is widely used in tunnel breakthrough surveying, mine roadway traverse laying, geological exploration, and engineering surveying—occurring in situations requiring long-term stable observation. To ensure measurement accuracy, the gyro-orientation instrument must be fixed in a predetermined posture position using a tripod or other supporting device. With the increasing complexity of field operating environments and the frequency of measurement tasks, tripods not only need to possess good load-bearing capacity and stability but also need to be lightweight, portable, and capable of rapid deployment to meet the application needs of measurement tasks in multiple locations and under various working conditions.

[0003] Existing gyro-direction tripods typically consist of a top support and three sets of retractable legs, with a limiting structure between the legs to control the tripod's tilt angle and maintain overall stability. This limiting structure in current technology usually employs a rigid support structure capable of synchronously extending and adjusting the three sets of retractable legs, achieving limiting through a fixed geometric relationship between the legs. While this structure performs well in terms of stability, it suffers from drawbacks in practical applications, such as significant weight, inconvenience in carrying, and large storage volume. In measurement tasks requiring frequent movement and multiple deployments, it can easily increase the burden on operators and reduce deployment efficiency.

[0004] It is evident that existing rigid support-type limiting structures, while ensuring stability, often sacrifice lightweight and portability, making it difficult to meet the comprehensive requirements of weight, storage, and deployment efficiency for long-term, multiple-station measurement tasks. Utility Model Content

[0005] This application provides a gyro orientation tripod to solve the problems of excessive weight and inconvenience in carrying existing gyro orientation tripods.

[0006] This application provides a gyro orientation instrument tripod, including a ring instrument base, three sets of leg tube assemblies, a gap limiting mechanism, and three sets of ground feet assemblies;

[0007] The annular instrument support is evenly hinged with three sets of independently telescopic and adjustable leg tube assemblies. The center of the annular instrument support has a through circular hole. The outer periphery of the annular instrument support is evenly provided with three tightening screws for multi-point radial clamping of the outer wall of the gyroguide installed in the circular hole. The three sets of leg tube assemblies are connected by a detachable opening limit mechanism for limiting the tilt angle of the three sets of leg tube assemblies when they are deployed. The opening limit mechanism includes a tension band that surrounds the three sets of leg tube assemblies and forms a triangular surrounding structure when the three sets of leg tube assemblies are deployed together, and three hooks located at the three corners of the tension band. The opening limit mechanism is detachably connected to the three sets of leg tube assemblies through the three hooks. The lower end of each of the three sets of leg tube assemblies is connected to a set of foot assemblies.

[0008] In one alternative embodiment, the foot tube assembly includes a rotating tube assembly, an adjusting tube assembly, and a locking mechanism;

[0009] The upper end of the rotating tube assembly is hinged to the annular instrument support. An adjusting tube assembly that can be slidably connected to the rotating tube assembly and can be extended and adjusted relative to the rotating tube assembly in the length direction is provided. The lower end of the adjusting tube assembly is connected to the foot assembly. The adjusting tube assembly is also provided with a locking mechanism for fixing the adjusting tube assembly relative to the rotating tube assembly.

[0010] In one optional embodiment, the foot assembly includes a foot fixing base, a pivot, and a support foot. The foot fixing base is connected to the lower end of the foot tube assembly. The bottom of the foot fixing base is provided with an insertion end for inserting into the ground. The lower part of the foot fixing base is also provided with the rotatable pivot. The foot fixing base is connected to the support foot, which can rotate with the pivot, through the pivot. The support foot can be used to contact the ground for support. Both ends of the pivot are connected with latches that can restrict the rotation of the pivot.

[0011] In one alternative embodiment, the tensioning band is provided with a length adjustment buckle, which is used to adjust the effective circumference of the tensioning band to adapt to the unfolding angle of the leg tube assembly.

[0012] In one alternative embodiment, the tensioning band is made of fiber webbing, the material of which is one or a combination of polyester, nylon or aramid, and the width of the tensioning band is 20 to 60 mm and the thickness is 0.8 to 2.5 mm.

[0013] In one alternative embodiment, the rotating tube assembly includes a top hinge joint, two parallel first connecting tubes, and a bottom connecting seat. The upper part of the top hinge joint is hinged to the annular instrument support, and the lower part of the top hinge joint is connected to the two first connecting tubes. The other ends of the two first connecting tubes are connected to the bottom connecting seat.

[0014] The adjustment tube assembly includes a top sliding seat, two parallel second connecting tubes, and a bottom fixing seat. The top sliding seat is slidably connected to the two first connecting tubes. Two second connecting tubes are connected to the top sliding seat. The two second connecting tubes are located between the two first connecting tubes, and the lower ends of the two second connecting tubes pass through the bottom connecting seat and are connected to the bottom fixing seat.

[0015] In one optional embodiment, the locking mechanism is a double locking device capable of fixing the upper and lower ends of the rotating tube assembly respectively; the locking mechanism includes a first locking device disposed at the upper part of the adjusting tube assembly and a second locking device disposed at the lower part of the rotating tube assembly.

[0016] In one alternative embodiment, the annular instrument base and the three sets of leg tube assemblies are both made of carbon fiber.

[0017] Compared with the prior art, this application has the following beneficial effects:

[0018] 1. This application provides a gyroguide tripod with a split-end limiting mechanism between three leg tube assemblies. This mechanism consists of a tension band and three hooks. When the tripod is unfolded, the three hooks tighten the tension band to form a triangular surrounding structure. This structure, through a "closed perimeter + three-point connection" method, transforms the originally freely variable split-end positions between the three leg tube assemblies into a stable structural relationship limited by the length of the tension band. Because this split-end limiting mechanism is detachable, it can be quickly unhooked and separated from the leg tube assemblies when not in use, thus reducing protruding parts when the tripod is folded, making the overall shape more compact and easier to pack into a transport bag for carrying and storage. Simultaneously, the combination of the tension band and hooks significantly reduces weight compared to traditional metal rod-type rigid limiting structures, lowering the total weight of the tripod and making long-distance transport easier. Once the operator extends or retracts the three leg tube assemblies to the target height and unfolds them to the appropriate angle, the tension band is under tension, forming a triangular structure with a certain circumference. This allows the tripod to provide more convenient and stable support during use. As long as the circumference of the tension band around the formed triangular structure remains constant, the spatial angle between the three leg tube assemblies will tend to be consistent over multiple deployments, thus helping to improve the angle consistency across different work sites. Furthermore, the flexibility of the tension band allows it to be naturally rolled or folded during storage, occupying less space and further enhancing the portability and on-site deployment efficiency of the entire system.

[0019] 2. At the upper end of the tripod, the circular through-hole of the annular instrument support of this application engages with three evenly distributed radially clamping screws, enabling multi-point clamping of the outer wall of the gyroguide installed within the through-hole. This forms an evenly distributed hinged connection with the three sets of leg tube assemblies, creating a stable upper support relationship between the instrument and the tripod. The opening and limiting mechanism in the middle, through a tension band and three hooks, encloses the three sets of leg tube assemblies into a triangular structure in the unfolded state, ensuring that the unfolding tilt angle between the three sets of leg tube assemblies is within a set range, while preventing excessive outward extension of the leg tube assemblies. Since the opening and limiting mechanism is detachable, it can be removed individually during transportation and storage, reducing interference with other components and lowering the risk of bumps and wear during handling. The lower foot assembly establishes supporting contact with the ground, providing a load-bearing and positioning foundation for the entire system. This structural layout, from upper clamping and middle limiting to lower support, gives the tripod a relatively stable spatial geometry after the instrument is installed, reducing attitude deviation caused by angle changes during use and helping to maintain high consistency and stability in multiple deployment operations.

[0020] 3. This application separates "height adjustment" from "spread angle control." The three sets of leg tube assemblies can be independently extended and retracted to adjust the height. The spread angle is locked using a three-point hook connection with the tension band. Finally, each leg assembly forms a reliable support with the ground. This method ensures that adjusting the tripod height does not affect the spread angle of each leg tube assembly, and the spread angle of the leg tube assembly is independent of the extension and retraction adjustment of the leg tube assembly, reducing the possibility of "angle changes caused by height adjustment" from an operational mechanism perspective. Furthermore, since the spread limit mechanism is a detachable flexible component, disassembly and assembly require no additional tools, enabling rapid deployment and dismantling during field operations, shortening preparation time and improving operational efficiency. Compared to traditional fixed rigid limit rods, its flexible material and detachable structure effectively reduce the number of metal parts, lowering production and maintenance costs. Moreover, because each leg tube assembly can be independently extended and retracted to adjust its height, the tripod can adapt well to different terrain conditions, even in uneven ground environments, and can be adjusted to a near-level support state.

[0032] Please see Figures 1-4 , Figure 1This is a schematic diagram of the overall structure of a gyroscope orientation tripod provided in an embodiment of this application; Figure 2 This is a schematic diagram of the structure of a leg tube assembly provided in one embodiment of this application; Figure 3 This is a schematic diagram of the structure of a ring-shaped instrument support provided in one embodiment of this application; Figure 4 This is a schematic diagram of the structure of a foot assembly provided in one embodiment of this application. Figures 1-4 As shown in the figure, this application provides a gyro orientation instrument tripod, including a ring instrument support 100, three sets of leg tube assemblies 200, a gap limiting mechanism 300, and three sets of foot assemblies 400.

[0033] The annular instrument support 100 is evenly hinged with three sets of independently telescopic and adjustable leg tube assemblies 200. The center of the annular instrument support 100 is provided with a through circular hole 101. Three tightening screws 102 are evenly arranged on the outer periphery of the annular instrument support 100 for multi-point radial clamping of the outer wall of the gyroguide installed in the circular hole 101. The three sets of leg tube assemblies 200 are connected by a detachable opening limit mechanism 300 for limiting the tilt angle of the three sets of leg tube assemblies 200 when they are unfolded. The opening limit mechanism 300 includes a tension band 301 that surrounds the three sets of leg tube assemblies 200 and forms a triangular surrounding structure when the three sets of leg tube assemblies 200 are unfolded together, and three hooks 302 are provided at the three corners of the tension band 301. The opening limit mechanism 300 is detachably connected to the three sets of leg tube assemblies 200 through the three hooks 302. The lower end of each of the three sets of leg tube assemblies 200 is connected to a set of foot assemblies 400.

[0034] The gyroguide tripod provided in this embodiment features a gap-limiting mechanism 300 between the three leg tube assemblies 200. This mechanism 300 consists of a tension band 301 and three hooks 302. When the tripod is unfolded, the three hooks 302 tighten the tension band 301 to form a triangular surrounding structure. This structure, through a "closed perimeter + three-point connection" method, transforms the originally freely variable gap positions between the three leg tube assemblies 200 into a stable structural relationship limited by the length of the tension band 301. Since the gap-limiting mechanism 300 is detachable, it can be quickly unhooked and separated from the leg tube assemblies 200 when not in use. This reduces protruding parts when the tripod is folded, making the overall shape more compact and easier to pack into a transport bag for carrying and storage. Simultaneously, the combination of the tension band 301 and hooks 302 has a significant weight-reduction effect compared to traditional metal rod rigid limiting structures, reducing the total weight of the tripod and making long-distance transport easier. When the operator extends or retracts the three sets of leg tube assemblies 200 to the target height and unfolds them to the appropriate angle, the tension band 301 is under tension, forming a triangular structure with a certain circumference. This allows the tripod to provide more convenient and stable support during use. As long as the circumference of the triangular structure formed by the tension band 301 remains constant, the spatial angle of the three sets of leg tube assemblies 200 will tend to be consistent in multiple deployments, thus helping to improve the angle consistency of different work sites. In addition, the flexibility of the tension band 301 allows it to be naturally rolled or folded when stored, occupying less space and further improving the portability and on-site deployment efficiency of the entire equipment.

[0035] At the upper end of the tripod, the circular through-hole 101 of the annular instrument support 100 engages with three evenly distributed radially clamping screws 102, allowing for multi-point clamping of the outer wall of the gyroguide installed within the through-hole. This also forms evenly distributed hinged connections with the three leg tube assemblies 200, creating a stable upper support relationship between the instrument and the tripod. The middle opening and limiting mechanism 300, through a tension band 301 and three hooks 302, encloses the three leg tube assemblies 200 in their unfolded state into a triangular structure, ensuring that the unfolding tilt angle between the three leg tube assemblies 200 is within a set range, while preventing excessive outward extension of the leg tube assemblies 200. Since the opening and limiting mechanism 300 is detachable, it can be removed individually during transportation and storage, reducing interference with other components and lowering the risk of bumps and wear during handling. The lower foot assembly 400 establishes supporting contact with the ground, providing a foundation for overall load-bearing and positioning. This structural layout, from upper clamping and middle limiting to lower support, gives the tripod a relatively stable spatial geometry after the instrument is installed, reducing attitude deviation caused by angle changes during use and helping to maintain high consistency and stability in multiple deployment operations.

[0036] This embodiment separates "height adjustment" from "spread angle control." The three sets of leg tube assemblies 200 can be independently extended and retracted to adjust the height. The spread angle is locked using a three-point hook connection with the tension band 301. Finally, the various leg assemblies 400 provide reliable support to the ground. This method ensures that adjusting the tripod height does not affect the spread angle of each leg tube assembly 200, and the spread angle of the leg tube assemblies 200 is independent of their extension and retraction. This reduces the likelihood of "angle changes caused by height adjustment" from an operational mechanism perspective. Furthermore, since the spread limit mechanism 300 is a detachable flexible component, disassembly and assembly require no additional tools, allowing for rapid deployment and retrieval during field operations, shortening preparation time and improving operational efficiency. Compared to traditional fixed rigid limit rods, its flexible material and detachable structure effectively reduce the number of metal parts, lowering production and maintenance costs. Moreover, since each leg assembly 200 can be independently extended and height adjusted, the tripod can adapt well to different terrain conditions for adjusting the leg assembly 200. Even in environments with uneven ground, it can be adjusted to a near-level support state.

[0037] In some embodiments, the foot tube assembly 200 includes a rotating tube assembly 201, an adjusting tube assembly 202, and a locking mechanism 203.

[0038] The upper end of the rotating tube assembly 201 is hinged to the annular instrument support 100. An adjusting tube assembly 202 that can be slidably connected to the rotating tube assembly 201 and can be extended and adjusted relative to the rotating tube assembly 201 in the length direction is provided. The lower end of the adjusting tube assembly 202 is connected to the foot assembly 400. The adjusting tube assembly 202 is also provided with a locking mechanism 203 for fixing the adjusting tube assembly 202 relative to the rotating tube assembly 201.

[0039] In this embodiment, the leg tube assembly 200 adopts a structure consisting of a rotating tube assembly 201, an adjusting tube assembly 202, and a locking mechanism 203. The upper rotating tube assembly 201 is connected to the annular instrument support 100 via a hinge, giving the leg tube assembly 200 a certain degree of rotational capability at the connection point. This facilitates flexible adjustment of the leg tube assembly 200's placement direction during deployment to adapt to different ground location requirements. The adjusting tube assembly 202 slides along the length of the rotating tube assembly 201, allowing the effective length of the leg tube assembly 200 to be changed without moving the hinge position. This ensures that the angle and height adjustment of the tripod are primarily completed within the leg tube assembly 200, and facilitates separating height adjustment from deployment angle control. The locking mechanism 203 is used to fix the leg tube assembly 200 after it has been adjusted to the required length, ensuring the leg tube assembly 200's length remains stable during use and reducing the possibility of height changes caused by sliding.

[0040] In some embodiments, the foot assembly 400 includes a foot fixing base 401, a rotating shaft 402, and a support foot 403. The foot fixing base 401 is connected to the lower end of the foot tube assembly 200. The bottom of the foot fixing base 401 is provided with an insertion end 4011 for inserting into the ground. The lower part of the foot fixing base 401 is also provided with a rotatable rotating shaft 402. The foot fixing base 401 is connected to the support foot 403, which can rotate with the rotating shaft 402, through the rotating shaft 402. The support foot 403 can be used to contact the ground for support. The two ends of the rotating shaft 402 are connected with latches 4021 that can restrict the rotation of the rotating shaft 402.

[0041] In this embodiment, the structure of the foot assembly 400 allows for flexible selection of different landing methods based on site conditions. When working on soft or insertable ground, the insertion end 4011 at the bottom of the foot fixing base 401 can be directly inserted into the ground to create a certain amount of soil resistance and adhesion, thereby enhancing support stability. On hard or smooth ground, the support foot 403 can be lowered via the pivot 402 to create a larger contact area with the ground and obtain higher friction. The locking buckle 4021 restricts the position of the pivot 402, keeping the support foot 403 in the adjusted posture and preventing rotation. The two landing methods can be quickly switched within the same structure, reducing the need for frequent adjustments to the foot tube assembly 200 and ensuring stable support for the tripod in different working environments.

[0042] Optionally, a mounting plate 2001 is provided on one side of the lower end of the leg assembly 200 for attaching the latch 4021. The mounting plate 2001 is provided with multiple grooves for attaching the latch 4021.

[0043] In this embodiment, the mounting plate 2001 allows the latch 4021 to select different mounting positions based on the contact state between the support foot 403 and the ground when locking the support foot 403. Multiple grooves provide tiered mounting points, allowing the operator to fix the latch 4021 in the most suitable groove according to the ground height difference or the rotation angle of the support foot 403. This restricts the rotation of the shaft 402 while maintaining the support foot 403 in full contact with the ground. This not only helps achieve stable support on grounds of varying inclinations or materials but also allows for quick locking after the support foot 403 is adjusted, reducing the time spent on repeated fine-tuning and improving deployment efficiency.

[0044] In some embodiments, a length adjustment buckle 3011 is provided on the tension band 301. The length adjustment buckle 3011 is used to adjust the effective circumference of the tension band 301 to adapt to the unfolding angle of the leg tube assembly 200.

[0045] In this embodiment, the tension band 301 is equipped with a length adjustment buckle 3011, which allows the effective length of the tension band 301 to be adjusted during use, thereby changing the effective circumference of the closed structure it forms. In this way, the tension band 301 can maintain a suitable tension at different deployment angles of the leg tube assemblies 200, thus playing a constraining role in stabilizing the angle between the leg tube assemblies 200. When a smaller deployment angle is required, the effective circumference of the tension band 301 can be appropriately shortened to prevent the band from becoming too loose and weakening the limiting effect; when a larger deployment angle is required, the effective circumference can be increased. The adjustable characteristic of the effective circumference allows the tension band 301 to maintain a relatively balanced stress state under different terrain conditions and height adjustments, thereby helping to maintain the stability of the geometric relationship between the three legs and achieving high angle consistency and repeatability accuracy during multiple deployments.

[0046] In practical applications, the length adjustment buckle 3011 can be similar in form to the shoulder strap adjustment buckle of a backpack to increase or decrease the effective length of the tensioning band 301. The operator only needs to push the length adjustment buckle 3011 or adjust the sliding position of the band within it to quickly tension the circumference of the band 301 to adapt to different deployment states of the leg tube assembly 200. This method is technologically mature and offers a wide range of material choices. Those skilled in the art can flexibly design the size and shape of the adjustment buckle according to specific needs, thereby achieving reliable length adjustment without increasing complexity.

[0047] In some embodiments, the tension band 301 is made of fiber webbing, the material of which is one or a combination of polyester, nylon or aramid, and the width of the tension band 301 is 20 to 60 mm and the thickness is 0.8 to 2.5 mm.

[0048] Tensioner 301 uses polyester, nylon, or aramid fiber webbing, with a width limited to 20–60 mm and a thickness limited to 0.8–2.5 mm to achieve a good balance between strength, flexibility, and weight. Polyester and nylon have good abrasion resistance and tensile strength, suitable for repeated tensioning and long-term outdoor use, and their structural stability is not easily compromised; aramid has high cut resistance and heat resistance, which can improve overall reliability in high-temperature or complex environments. The width is controlled at 20–60 mm, and the thickness ranges from 0.8–2.5 mm, which avoids affecting the convenience of winding and storage due to excessive width, while retaining a certain degree of softness, making the length adjustment buckle 3011 easier to adjust.

[0049] In some embodiments, the rotating tube assembly 201 includes a top hinge joint 2011, two parallel first connecting tubes 2012, and a bottom connecting seat 2013. The upper part of the top hinge joint 2011 is hinged to the annular instrument support 100, and the lower part of the top hinge joint 2011 is connected to the two first connecting tubes 2012. The other ends of the two first connecting tubes 2012 are connected to the bottom connecting seat 2013.

[0050] The adjusting tube assembly 202 includes a top sliding seat 2021, two parallel second connecting tubes 2022, and a bottom fixing seat 2023. The top sliding seat 2021 is slidably connected to the two first connecting tubes 2012. The top sliding seat 2021 is connected to two second connecting tubes 2022. The two second connecting tubes 2022 are located between the two first connecting tubes 2012, and the lower ends of the two second connecting tubes 2022 pass through the bottom connecting seat 2013 and are connected to the bottom fixing seat 2023. In this embodiment, the bottom fixing seat 2023 is connected to a foot assembly 400. Specifically, the bottom fixing seat 2023 is connected to the foot fixing seat 401.

[0051] This embodiment employs a parallel arrangement of two tubes, the rotating tube assembly 201 and the adjusting tube assembly 202, forming a mating connection at the top and bottom. This provides the leg tube assembly 200 with excellent guiding properties and load-bearing stability during telescopic adjustment. The dual-tube structure not only helps maintain the relative positional stability of each component during telescopic adjustment but also allows the operator to adjust the length of the leg tube assembly 200 more smoothly. As the top sliding seat 2021 slides along the first connecting tube 2012, the second connecting tube 2022, connected to the top sliding seat 2021, maintains its parallel relationship with the first connecting tube 2012, thereby reducing jamming and making the adjustment process smoother. During use, the load-bearing capacity is directly transmitted to the base assembly 400 through the bottom fixing seat 2023, reducing intermediate links in the load-bearing capacity transmission process and thus helping to maintain the overall stable support state of the leg assembly. In practical applications, to facilitate the hanging of hook 302, a connector with a hanging ring is provided on the second connecting tube 2022. This connector is fixedly connected to the two second connecting tubes 2022, and the hanging ring is installed on the inner side of the connector so that the position of the hanging ring matches the hook 302 of the tension band 301. In use, the operator can directly hook the hook 302 into the hanging ring. The closed ring structure of the hanging ring prevents the hook 302 from falling off during stress or vibration, thereby ensuring that the tension band 301 always maintains a stable tension state between the foot tube assemblies 200.

[0052] Optionally, at least one set of leg tube assemblies 200 is provided with a handle 500, which is fixedly installed on the two second connecting tubes 2022 of the adjusting tube assembly 202. In actual use, the handle 500 also facilitates the movement or fine-tuning of the tripod without retracting it. This operation method not only improves the convenience of movement but also saves adjustment time while maintaining the stability of the tripod support.

[0053] In some embodiments, the locking mechanism 203 is a double locking device that can fix the upper and lower ends of the rotating tube assembly 201 respectively; the locking mechanism 203 includes a first locking device 2031 disposed at the upper part of the adjusting tube assembly 202 and a second locking device 2032 disposed at the lower part of the rotating tube assembly 201.

[0054] This embodiment employs a structure that simultaneously locks at both ends, allowing the leg tube assembly 200 to be fixed in two positions after length adjustment. The first locking device 2031 is located at the upper part of the adjusting tube assembly 202. After height setting, it quickly fixes the adjusting tube assembly 202 to the two first connecting tubes 2012 on the rotating tube assembly 201, thus suppressing length changes caused by axial sliding. The second locking device 2032 is located at the lower part of the rotating tube assembly 201, synchronously locking the connection between the lower rotating tube assembly 201 and the adjusting tube assembly 202, forming a dual-point fixing effect that complements the upper locking. By acting simultaneously at both ends, a stable force constraint is formed under support, reducing the possibility of loosening during handling, observation, or external impact. This ensures that the leg tube assembly 200 maintains high structural stability and reliability under different length settings and usage environments.

[0055] In some embodiments, the first locking device 2031 is disposed on the top sliding seat 2021, and the second locking device 2032 is disposed on the bottom connecting seat 2013. Optionally, the first locking device 2031 is a flip-type locking handle, and the second locking device 2032 is a rotary locking handwheel.

[0056] In this embodiment, the first locking device 2031 adopts a flip-type locking handle. Its structure may include a pressure plate mechanism disposed inside the top sliding seat 2021 and connected to the handle. When the operator flips the handle from the open position to the locked position, the pressure plate inside the top sliding seat 2021 applies a radial clamping force to the surface of the first connecting tube 2012, thereby fixing the top sliding seat 2021 in the current sliding position. The advantage of the flip operation is that the action is quick and the locking and releasing are convenient, making it suitable for parts that require frequent adjustment. The second locking device 2032 adopts a screw-type locking handwheel. The bottom connecting seat 2013 may be provided with a threaded rod connected to the handwheel and a pressure block connected to the threaded rod. When the handwheel is screwed, the pressure block is pressed radially against the second connecting tube 2022 through the threaded transmission, thereby fixing the position of the second connecting tube 2022 relative to the bottom connecting seat 2013. The screw-type structure has controllable locking force and large clamping force, making it suitable for parts that require long-term stable fixation. It should be understood that the first locking device 2031 and the second locking device 2032 are not limited to the above-mentioned structural forms. Other mechanical locking methods that can achieve position fixation, such as quick-release clamping rings, wedge block clamping structures, and spring pin snap-fit ​​structures, can also be adopted. The specific form can be selected according to actual usage requirements and processing conditions.

[0057] In some embodiments, the annular instrument support 100 and the three-legged tube assembly 200 are both made of carbon fiber.

[0058] In this embodiment, both the annular instrument support 100 and the three sets of leg tube assemblies 200 are made of carbon fiber, which significantly reduces the weight of the overall structure while maintaining sufficient rigidity. Carbon fiber has a higher specific strength and specific stiffness than commonly used metal materials. While meeting load-bearing requirements, the thickness of the tube walls and support can be reduced, thereby reducing the tripod's weight and facilitating handling and on-site deployment. Furthermore, carbon fiber has good dimensional stability and a low coefficient of thermal expansion. Even in environments with large day-night temperature differences or direct sunlight, the circular through-hole 101 of the annular instrument support 100 can maintain good dimensional accuracy, thus reducing the risk of gyro-orientation instrument positioning deviation caused by thermal expansion and contraction. Simultaneously, the carbon fiber structure has a certain damping effect on environmental vibrations, reducing the transmission of minor ground vibrations to the instrument, which helps improve the stability and accuracy of observations. Moreover, its corrosion resistance allows the tripod to maintain good condition for extended periods in complex field environments such as humid, salt spray, or high humidity conditions, thereby reducing maintenance frequency and extending service life.

[0059] The usage process of the gyroscope tripod in this embodiment is as follows:

[0060] Before use, remove the tripod from its carrying case. First, release the opening limit mechanism 300 to the unhooked state, thus slack off the tension band 301. The operator holds the ring-shaped instrument support 100 and sequentially rotates the three leg tube assemblies 200 outwards around the top hinge joint 2011 until they are nearly evenly distributed, thus establishing a preliminary tripod support on the ground. This provides a foundation for subsequent height adjustment and angle locking. At this point, the three leg tube assemblies 200 can swing freely to adapt to different terrains for initial positioning.

[0061] Based on the site terrain and operational requirements, slide the adjusting tube assembly 202 along the length of the rotating tube assembly 201 to set the extension length of the three sets of foot tube assemblies 200, so that the annular instrument support 100 reaches the required working height and tends to be horizontal. During the adjustment process, first use the first locking device 2031 to fix the adjusting tube assembly 202 in the preset position, and then operate the second locking device 2032 to assist in locking the lower end, forming a stable constraint with two fixed points at the top and bottom. If there is a large height difference on the ground, the length of a certain foot tube assembly 200 can be adjusted individually to ensure that the whole structure maintains stable support on uneven ground.

[0062] After height adjustment, the three hooks 302 of the opening limit mechanism 300 are respectively hooked onto the corresponding positions of the leg tube assemblies 200. The effective circumference of the tension band 301 is appropriately shortened or loosened by the length adjustment buckle 3011 to form a tightly tensioned triangular closed structure. This structure limits the maximum unfolding angle between the leg tube assemblies 200, reduces the possibility of the leg tube assemblies 200 swinging outward during operation, and maintains the consistency of the tripod angle during multiple deployments.

[0063] Select the appropriate landing mode for the anchor assembly 400 based on ground conditions: On soft soil or easily insertable ground, directly insert the insertion end 4011 of the anchor fixing base 401 into the ground to obtain high soil adhesion; on hard or smooth ground, rotate the locking buckle 4021 to lower the support foot 403, ensuring it makes full contact with the ground, and engage the locking buckle 4021 in the appropriate groove position of the mounting plate 2001 to restrict the rotation of the pivot 402, keeping the support foot 403 stably attached to the ground. This ensures stable support in various ground environments.

[0064] After the tripod is stabilized, place the gyroguide into the circular through hole 101 of the ring instrument holder 100, and evenly tighten the three locking screws 102 to form a multi-point clamping fixation on the outer wall of the instrument in the radial direction, ensuring position and attitude stability during observation. When the operation is finished, first loosen the locking screws 102 and remove the instrument, then loosen and unhook the opening limit mechanism 300 in sequence, fold up the three sets of leg tube assemblies 200, and reset the support feet 403. Finally, put the entire tripod into the storage bag for easy carrying and storage.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
