Description

Technical Field

[0001] This application belongs to the field of support and bracket technology, specifically relating to a device for reinforcing a tripod. Background Technology

[0002] Measuring instruments generally rely on support frames to ensure stable operation, with tripods being the most widely used form of support. For example, patent application number 202521193574.5 discloses a typical tripod structure, consisting of a top instrument mounting platform and three legs. Each leg has a conical grounding foot and an auxiliary foot pedal at its end, facilitating rapid anchoring by pressing the foot into the ground in soft geological conditions. This provides a high-rigidity, low-disturbance reference support platform for the measuring instrument, ensuring the accuracy of observation data and images.

[0003] With the diversification of measurement work scenarios, the application environment of tripods is becoming increasingly complex. Tripods not only need to stably support instruments on soft ground, but also need to meet the requirements for use on high-strength hardened surfaces such as asphalt and concrete. To solve this adaptability challenge, most existing technologies focus on optimizing the tripod's own structure. For example, patent application number 202510591164.4 adopts a design that adds a base plate to the end of the legs, effectively increasing the friction between the tripod and the ground by expanding the contact area with the ground, thereby enhancing stability on smooth surfaces such as hardened roads. Another solution, application number 202510704301.0, sets a slider mechanism with an axle in the middle of the legs, and connects the slider to the three legs of the tripod through three connecting rods to form a linkage structure. This design can achieve precise locking of the distance and angle between the legs, further strengthening the overall structural stability of the tripod and enabling it to maintain good support performance in various complex environments. In addition, a few studies have attempted to introduce external auxiliary reinforcement systems, such as a tripod collaborative stabilization device disclosed in CN202411666142.1. This device includes a central mounting base and three sets of extended support boxes hinged to the outer wall of the central mounting base. Multiple positioning slots are provided within the support boxes. In use, the stabilization device is placed horizontally and fixed to a hard surface, and then the tripod legs are inserted into the positioning slots within the support boxes to form a composite support interface. This composite support interface can significantly enhance the overall anti-overturning moment, allowing the tripod to remain stable even on hardened surfaces or other difficult-to-fix locations, providing strong support for the smooth conduct of measurement and other operations.

[0004] However, despite the progress made by the aforementioned technologies in improving the stability of tripods on hardened surfaces, their practical application still faces significant limitations. Especially in complex working environments, measurement points are often located on slopes, undulating ground, or uneven paved surfaces. Existing designs—whether adding a base plate, a linkage angle locking mechanism, or installing a support box device outside the central mounting base—highly rely on a complete and horizontal fit between the bottom of the support structure and the ground. If the ground slopes both longitudinally and laterally, individual legs or support boxes can easily become suspended, resulting in uneven load distribution and stress concentration. This not only weakens the overall structural rigidity but may also induce local buckling or instability, seriously affecting measurement accuracy and equipment safety. Utility Model Content

[0005] The purpose of this application is to provide a tripod reinforcement device that can operate stably in complex environments, which is achieved through the following technical solution:

[0006] A tripod reinforcement device includes a base with a plurality of extension bodies hinged to it. Each extension body has a positioning groove for fixing the free end of a tripod leg. At least one extension body includes a height adjustment assembly hinged to the base for rotating up and down around the hinge point, and an angle adjustment assembly connected to the end of the height adjustment assembly away from the base via a torsion member and having the positioning groove provided thereon. Along the axial direction of the extension body, the angle between the height adjustment assembly and the angle adjustment assembly at their closest points changes with adjustment of the torsion member.

[0007] In this application, the angle between the height adjustment component and the angle adjustment component at their closest points refers to the angle between the lower surface of the height adjustment component and the lower surface of the angle adjustment component during the use of the tripod reinforcement device.

[0008] Preferably, the positioning slots are linearly arrayed on the upper surface of the epitaxial body, and the size of the positioning slots gradually increases from the hinge end to the free end of the epitaxial body. The positioning slots penetrate the epitaxial body, and the upper surface of the epitaxial body is also provided with an intercepting surface for abutting against the lower end of the tripod's foot pedal. The gradual increase in the size of the positioning slots means that the size of several positioning slots gradually increases along the direction from the hinge end to the free end of the epitaxial body.

[0009] Preferably, the torsion member is composed of a sleeve-pin linkage mechanism. The sleeve is integrated into the angle adjustment component or the height adjustment component, and the pin is correspondingly disposed on the angle adjustment component or the height adjustment component. At least a portion of the pin is installed in the receiving cavity of the sleeve via axial assembly. The sleeve-pin linkage mechanism further includes a limiting member to prevent the pin from disengaging from the receiving cavity of the sleeve. More preferably, the limiting member is a cotter pin that penetrates the end of the pin, thereby restricting the pin from disengaging.

[0010] Preferably, the torsion member is disposed on the near-ground side of the reinforcement device; the extension body also includes a bottom contact area for contacting the ground, and a transition side wall connecting the upper surface of the extension body and the bottom contact area, the height of the transition side wall being greater than the height of the vertical space occupied by the sleeve pin linkage mechanism.

[0011] Preferably, the hinged part adopts a double bearing sleeve rotary joint, which includes an end bearing sleeve integrated on the height adjustment component or the base, and a rotating shaft correspondingly disposed on the height adjustment component or the base and installed in the end bearing sleeve; the double bearing sleeve rotary joint also includes a stop plate to prevent the horizontal height of the height adjustment component from being lower than that of the base.

[0012] Preferably, the reinforcement device further includes a fixing member for securing the angle adjustment assembly to the ground.

[0013] A measurement auxiliary device includes a tripod and a tripod reinforcement device as described in any one of the above claims, wherein the tripod legs are telescopic legs.

[0014] Preferably, the base has an observation hole in the middle that corresponds to the central axis of the tripod.

[0015] Compared with the prior art, this application has the following beneficial effects:

[0016] This application incorporates a height adjustment component, allowing the extension body to rotate up and down around the hinged portion with the base. Simultaneously, it includes an angle adjustment component with a torsion member, enabling the angle between the height and angle adjustment components near one end to change with the torsion member's adjustment. This overcomes the existing technology's reliance on the ground for tripod-based stabilization devices, allowing for flexible adaptation to complex working environments with slopes in both longitudinal and transverse directions. It also significantly improves the overall structure's anti-overturning capability, effectively avoiding stress concentration, local buckling, or instability caused by uneven ground, thus ensuring measurement accuracy and equipment safety.

[0017] This application uses a linear array of positioning slots distributed on the upper surface of the extension body, with the size gradually increasing from the hinged end to the free end. This allows the slots to be adapted to the tilt angle of the tripod legs, thus firmly fixing the legs in the positioning slots. It also provides more options for fixing the legs, facilitating flexible adjustment of the support points according to the terrain. By setting the positioning slots through the extension body, combined with the intercepting surface on the upper surface of the extension body that abuts against the lower end of the tripod pedal, axial limiting can be achieved through the contact between the pedal and the intercepting surface. This, combined with the radial constraint of the legs by the through-type positioning slots, ensures the legs are firmly fixed within the positioning slots, preventing axial sliding or radial displacement of the legs during operation and further enhancing the reliability of the support.

[0018] This application sets the torsion member as a sleeve-pin linkage mechanism, with the sleeve integrated into the angle adjustment component or the height adjustment component, and the pin correspondingly set in another component. At least part of the pin is axially assembled in the sleeve receiving cavity, which enables flexible relative rotation between the angle adjustment component and the height adjustment component, providing a stable structural basis for precise adjustment of the included angle between the two. By setting a limiting component in the sleeve-pin linkage mechanism to prevent the pin from disengaging from the sleeve receiving cavity, the reliability of the connection between the sleeve and the pin can be effectively guaranteed, avoiding adjustment failure due to component separation during angle adjustment, thereby ensuring the structural stability and safety of the overall device.

[0019] This application reduces the impact of external collisions on the torsion component by placing the torsion member on the near-ground side of the reinforcement device. At the same time, it utilizes the near-ground space to achieve a compact connection between the angle adjustment component and the height adjustment component, optimizing the overall structural layout. By making the height of the transition side wall of the extension body greater than the vertical space occupied by the sleeve pin linkage mechanism, it can provide effective structural protection for the sleeve pin linkage mechanism. Meanwhile, the transition side wall can enhance the overall structural strength of the extension body, improve stability when in contact with the ground, and ensure the reliable realization of the torsion adjustment function.

[0020] This application sets the hinge portion as a double-bearing sleeve rotary joint, with the end bearing sleeve integrated into the height adjustment component or base, and the rotating shaft correspondingly set in another component and installed in the end bearing sleeve. This enables smooth rotation between the height adjustment component and the base, providing stable and flexible structural support for the extension body to flip up and down around the hinge portion, ensuring the accurate realization of the height adjustment function. By setting a stop plate in the double-bearing sleeve rotary joint to prevent the horizontal height of the height adjustment component from falling below the base, the flipping range of the height adjustment component can be effectively limited, avoiding structural interference between the extension body and the base or affecting the overall support balance due to excessive flipping, thereby ensuring the safety and stability of the device during the height adjustment process.

[0021] This application strengthens the connection between the angle adjustment component and the ground by setting a fixing member in the reinforcement device to fix the angle adjustment component to the ground, and avoids displacement or tilting of the angle adjustment component due to external disturbance, thus providing a stable support foundation for the tripod legs in the positioning groove.

[0022] This application, by setting the tripod legs as telescopic legs, allows for flexible adjustment of the leg length to adapt to the positioning slots of reinforcement devices at different terrains and heights, thereby ensuring that the central mounting base is level and facilitating the installation of testing equipment. Furthermore, by setting an observation hole in the middle of the base, corresponding to the central axis of the tripod, operators can directly observe the positioning point below through the observation hole, confirming the alignment of the equipment with the positioning point without frequent device movement, thus improving the operational convenience and positioning accuracy of measurement operations.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Those skilled in the art will be able to implement the present invention based on these descriptions. Furthermore, the embodiments of the present invention described below are generally only a part of the embodiments of the present invention, and not all of the embodiments. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Example 1:

[0030] A tripod reinforcement device includes an equilateral triangular base 100 located at the center, with three extension bodies 200 hinged to the three sides of the base 100 respectively. Each extension body 200 includes a height adjustment component 220 hinged to the base 100 for rotating up and down around the hinge portion 300, and an angle adjustment component 230 connected to the end of the height adjustment component 220 away from the base 100 via a torsion member 400 and provided with a positioning groove 210. Along the axial direction of the extension body 200, the included angle between the height adjustment component 220 and the angle adjustment component 230 at their respective ends changes with the adjustment of the torsion member.

[0031] In this embodiment, the extension body 200 is provided with four sets of positioning grooves 210 for fixing the free ends of the tripod legs; the positioning grooves 210 are linearly arrayed on the upper surface of the extension body 200, and the size of the positioning grooves 210 gradually increases from the hinge end of the extension body 200 towards the free end. To further enhance the support effect of the tripod, in this embodiment, the positioning grooves 210 penetrate the extension body 200, and the upper surface of the extension body 200 is also provided with an intercepting surface 240 for abutting against the lower end of the tripod foot pedal.

[0032] In this embodiment, the torsion member 400 is composed of a sleeve-pin linkage mechanism. The sleeve 410 is integrated on the angle adjustment component 230, and the pin 420 is correspondingly disposed on the height adjustment component 220. At least a portion of the pin 420 is axially mounted in the receiving cavity of the sleeve 410. The sleeve-pin linkage mechanism also includes a limiting member 430 to prevent the pin 420 from disengaging from the receiving cavity of the sleeve 410. Specifically, in this embodiment, the end of the pin 420 protrudes from the sleeve 410, and the limiting member 430 is a cotter pin that penetrates the protruding end of the pin 420 to restrict the pin 420 from disengaging. In this embodiment, the torsion member 400 is disposed on the upper surface of the extension body 200.

[0033] In this embodiment, the hinge portion 300 employs a double-bearing sleeve rotary joint. The double-bearing sleeve rotary joint includes an end bearing sleeve 310 integrated into the height adjustment assembly 220, and a rotating shaft 320 correspondingly disposed on the base 100 and installed within the end bearing sleeve 310. The double-bearing sleeve rotary joint also includes a stop plate 330 to prevent the horizontal height of the height adjustment assembly 220 from falling below that of the base 100. Furthermore, to further increase the stability of the extension body 200, the reinforcement device in this embodiment also includes a fixing member for fixing the angle adjustment assembly 230 to the ground.

[0034] When using the device on a surface with slopes both longitudinally and laterally, the operator must first locate the initial position of the extension body 200 on the slope. At this point, the height adjustment component 220 of the extension body 200, positioned on the slope, can flexibly rotate upwards around the hinge 300. As the rotation angle increases, the overall height of the extension body 200 gradually rises until it reaches a height suitable for the measurement operation. Further, by rotating and adjusting the torsion member 400, the tilt angle of the angle adjustment component 230 can be precisely controlled until its lower end is firmly in contact with the sloped ground. Then, the fixing member is aligned with the preset fixing point on the ground and firmly fixed using tools. During the fixing process, it is necessary to ensure that the fixing member is embedded to the required depth to guarantee the stability of the overall structure. At this point, the installation base of the tripod reinforcement device is complete. Finally, the bottom of the tripod is inserted into the positioning groove 210 on the extension body 200 until the bottom of the tripod is fully in contact with the intercepting surface 240. At this point, the tripod can be stably installed on the reinforcement device, effectively resisting external interference even in sloping environments, and providing support for measurement operations.

[0035] Example 2:

[0036] A measurement auxiliary device includes a tripod and a tripod reinforcement device, wherein the tripod legs are telescopic. The difference between the tripod reinforcement device and that of Embodiment 1 is that in this embodiment, the torsion member 400 is located on the ground-near side of the reinforcement device; the extension body 200 also includes a bottom contact area 250 for contacting the ground, and a transition side wall 260 connecting the upper surface of the extension body 200 and the bottom contact area 250, the height of the transition side wall 260 being greater than the height of the vertical space occupied by the sleeve pin linkage mechanism. Furthermore, in this embodiment, an observation hole 110 corresponding to the central axis of the tripod is provided in the center of the base 100. Therefore, during use, by adjusting the extension length of the telescopic rod at the higher position, the central mounting base of the tripod can be made to be in a horizontal position, facilitating the installation of the inspection equipment.
