Description

Technical Field

[0001] This utility model relates to the field of bridge pier monitoring technology, and more specifically, to a laser scanning support structure for monitoring the verticality of high bridge piers in mountainous areas. Background Technology

[0002] During the construction of high bridge piers, the verticality of the piers is a crucial parameter affecting structural safety and service life, requiring precise monitoring. In existing technologies, laser scanning monitoring is a common high-precision measurement method, typically using a total station. However, in mountainous environments, the uneven terrain limits the capabilities of the tripods used with total stations.

[0003] First, conventional tripods are prone to sinking or tilting on soft soil or unstable rock surfaces, causing displacement of the total station during measurement and affecting monitoring accuracy. Furthermore, wind in mountainous environments can cause instrument swaying, making measurement data unstable and reducing reliability. Especially in high wind speeds, traditional tripods have limited wind resistance, making it difficult to ensure the stability of the measuring equipment, thus affecting measurement accuracy and data consistency.

[0004] Therefore, there is an urgent need for a total station support structure with high stability and strong wind resistance suitable for mountainous environments, in order to improve the adaptability and measurement accuracy of the measuring equipment. Utility Model Content

[0005] The purpose of this invention is to provide a laser scanning support structure for monitoring the verticality of high bridge piers in mountainous areas. This structure combines high stability with lightweight portability, thereby improving the adaptability of the measuring equipment in complex terrain.

[0006] This utility model is achieved through the following technical solution:

[0007] A laser scanning support structure for monitoring the verticality of high bridge piers in mountainous areas includes:

[0008] A support column, the top of which is used to mount the total station;

[0009] A bladder, coaxially disposed at the bottom of the support column, the bladder being configured as a groove-shaped form capable of expanding to a top opening, the bottom of the bladder being for contact with the ground;

[0010] An external support is provided, with multiple sets of external supports evenly arranged along the circumference of the support column. The external support includes an external support rod and an inclined support rod. One end of the external support rod is hinged to the support column and is embedded in the bottom of the bladder. One end of the inclined support rod is hinged to the external support rod and the other end is hinged to the support column near its top. The inclined support rod is telescopic.

[0011] A locking element is used to fix the position of the diagonal support rod after it has been extended or retracted.

[0012] Furthermore, the support includes a base plate, a tapered rod is fixedly installed at the bottom of the base plate, the bottom wall of the bladder is flush with the bottom wall of the base plate, and the outer support rod is hinged to the base plate.

[0013] Furthermore, multiple pull plates are arranged circumferentially inside the top opening of the bladder. The pull plates are elastically arranged and radially arranged outward from the support column. The pull plates divide the top opening of the bladder into multiple fan-shaped grooves.

[0014] Furthermore, a partition is provided inside the sector-shaped groove, which divides the sector-shaped groove into multiple compartments.

[0015] Furthermore, a reinforcing elastic ring is provided at the outer periphery of the top wall of the capsule.

[0016] Furthermore, the outer peripheral wall of the capsule expands into an arc-shaped outward convex shape, and the outer peripheral wall of the capsule is thickened.

[0017] Furthermore, multiple parallel elastic ropes are provided between adjacent outer support rods.

[0018] Furthermore, multiple connecting wires are provided inside the cavity of the capsule.

[0019] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0020] 1. This utility model expands the support area by placing the capsule on suitable mountainous terrain and inflating it. Then, materials such as sand and gravel are filled into the groove at the top opening of the capsule to form a stable support structure. Simultaneously, the external support rods and diagonal support rods of multiple external brackets are deployed, and the extension and retraction positions of the diagonal support rods are fixed by locking devices, further enhancing support stability. Because the capsule is lightweight and forms a large support surface after expansion, it can adapt to uneven ground, thus exhibiting high stability and combining the advantages of being lightweight and portable.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0029] Example

[0030] The following is for reference Figures 1-4 As shown in the illustration, and further illustrated with specific embodiments, this embodiment provides a laser scanning support structure for monitoring the verticality of high bridge piers in mountainous areas, specifically including the following components:

[0031] The support column 1 is located at the center of the structure, and its top is used to mount the total station 11 for high-precision verticality monitoring of the high bridge piers. The support column 1 has sufficient strength and stability to ensure that the total station 11 can remain stationary during use, thereby ensuring the accuracy of the measurement data.

[0032] The bladder 2 is coaxially mounted at the bottom of the support column 1. Its design allows the bladder 2 to expand into a groove-like shape with an open top. The bottom of the bladder 2 is in contact with the ground and can expand or contract as needed to adapt to uneven ground conditions and provide stable support. The expanded bladder 2 effectively increases the support area and improves the support effect. An air nozzle 21 is provided on the outside of the bladder 2 to facilitate inflation.

[0033] Multiple sets of external supports 3 are evenly arranged along the circumference of the support column 1. In this embodiment, four sets of external supports 3 are installed. Each set of external supports 3 includes an external support rod 31 and an inclined support rod 32. One end of the external support rod 31 is hinged to the support column 1, and the other end is embedded in the bottom of the bladder 2 to provide support. One end of the inclined support rod 32 is hinged to the external support rod 31, and the other end is hinged to the support column 1 near the top. The inclined support rod 32 is designed to be telescopic so that the support angle and length can be adjusted according to actual needs, thereby providing flexible support.

[0034] The locking element 4 is used to fix the inclined support rod 32 in its extended position. In this embodiment, the locking element 4 is a locking screw 41, which is easy for workers to tighten. The locking screw 41 ensures that the inclined support rod 32 remains stable after force is applied, thereby improving the stability and accuracy of the support structure. The locking element 4 can be quickly adjusted or unlocked when needed to facilitate the adjustment or disassembly of the support structure.

[0035] As an optional embodiment, the support column 1, the outer support rod 31 and the diagonal support rod 32 are all supported by high-strength plastic or carbon fiber to reduce the overall weight.

[0036] Reference Figure 1 and Figure 2 As shown, the support column 1 includes a base plate 12, with a tapered rod 121 fixedly installed at the bottom of the base plate 12. The tapered rod 121 can penetrate deep into the ground, improving the stability of the overall support structure and preventing displacement during use. The bottom wall of the bladder 2 is flush with the bottom wall of the base plate 12, ensuring that the expansion and support effect of the bladder 2 are not affected by uneven contact surfaces. One end of the outer support rod 31 is hinged to the base plate 12, providing a flexible support angle and enhancing the stability and adaptability of the support structure.

[0037] Reference Figure 1 and Figure 3As shown, multiple tension plates 22 are evenly arranged circumferentially within the top opening of the capsule 2. These tension plates 22 are made of elastic material to ensure effective shape stability during capsule 2 expansion. The tension plates 22 are arranged radially outward from the support column 1, forming multiple evenly spaced fan-shaped grooves 221. Each tension plate 22 not only helps stabilize the deformable shape of the capsule 2 but also prevents excessive deformation of the capsule 2 after filling the top groove with materials such as sand or gravel, ensuring that the support structure maintains a reasonable shape during use. Through this design, the tension plates 22 effectively limit excessive deformation of the capsule 2 during expansion, thereby improving the stability and service life of the capsule 2 and avoiding potential instability after material filling.

[0038] Reference Figure 1 As shown, each sector groove 221 is integrally provided with a partition 23, which is made of elastic material. In this embodiment, one partition 23 is installed in each sector groove 221. The partition 23 further divides the sector groove 221 into two chambers 231, thereby making the shape of the bladder 2 more stable during expansion. The partition 23 and the pull plate 22 work together to effectively prevent excessive deformation of the bladder 2 during expansion, ensuring that the bladder 2 can maintain a uniform and stable support shape after expansion.

[0039] Reference Figure 1 and Figure 3 As shown, a reinforcing elastic ring 24 is provided at the outer periphery of the top wall of the capsule 2. This reinforcing elastic ring 24 provides additional elastic support, further stabilizing the shape of the capsule 2 after deformation, while also improving the strength of the capsule 2 after expansion, enabling it to better withstand external pressure and environmental changes. The design of the reinforcing elastic ring 24 enhances the load-bearing capacity of the capsule 2, preventing it from rupturing or excessively deforming due to external impacts or uneven loads during use.

[0040] Furthermore, the outer peripheral wall of the capsule 2 convexes outward in an arc shape after expansion, enhancing its stability and support. The outer peripheral wall of the capsule 2 is thickened to improve its compressive strength and durability. The thickened outer peripheral wall not only allows the capsule 2 to provide a larger support area after expansion, but also effectively disperses the external forces acting on the capsule 2, thereby further enhancing the stability and safety of the support structure.

[0041] Reference Figure 2 and Figure 3As shown, multiple parallel elastic ropes 311 are installed between adjacent outer support rods 31, and these elastic ropes 311 are embedded within the bladder 2. These elastic ropes 311 play a crucial role in the stability of the support structure. By being evenly distributed between adjacent outer support rods 31, they effectively enhance the overall strength of the outer support 3. The elastic ropes 311 have a certain degree of tensile strength and elasticity, which can absorb external forces when the outer support rods 31 extend or contract, helping to maintain the stability of the outer support 3, and providing a certain buffering effect when the support structure deforms. In addition, the parallel arrangement of the elastic ropes 311 ensures uniform force distribution, further enhancing the deformation resistance of the support structure.

[0042] Reference Figure 3 As shown, multiple connecting wires 25 are installed inside the cavity of the capsule 2. These connecting wires 25 are manufactured integrally in the factory during the production of the capsule 2, and they play a crucial role in the structure of the capsule 2. By rationally arranging the connecting wires 25, the deformation shape of the capsule 2 can be effectively controlled, preventing uncontrolled deformation during expansion or contraction. These connecting wires 25 connect the various parts of the capsule 2 to each other, limiting the expansion range of the capsule 2 and ensuring that its shape change under stress is controllable. This prevents the capsule 2 from affecting its performance or causing instability due to excessive deformation. The design of the connecting wires 25 enables the capsule 2 to maintain higher stability in different environments, ensuring the long-term reliability and durability of the support structure.

[0043] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
