Description

Technical Field

[0001] This utility model belongs to the technical field of surveying instrument auxiliary devices, specifically relating to a portable measurement and monitoring auxiliary device. Background Technology

[0002] In recent years, the rapid development of engineering infrastructure in my country has placed increasingly higher demands on surveying work, requiring stricter precision in the accuracy of on-site data collection. Currently, with advancements in surveying technology and equipment, surveying methods have developed significantly. However, surveyors still face various challenges during their work. For example, in continuous beam monitoring, high-altitude operations are affected by wind, and the fact that measurement locations are often situated above reinforcing mesh makes it difficult to set up supporting surveying tools, leading to reduced accuracy, distorted data, and an inability to accurately reflect the actual stress changes in the beam, greatly reducing work efficiency. To address this issue, a portable measurement and monitoring auxiliary device has been invented.

[0003] For surveyors monitoring long-span continuous beams, prism erection personnel need to reach designated measurement positions and ensure the prism rods are precisely centered and leveled throughout the data acquisition process. However, due to harsh natural environments (wind, temperature, etc.) and the fact that many monitoring points are located on dense steel mesh, which is subject to human disturbance, the data collected by monitoring personnel cannot accurately reflect the actual stress state of the continuous beam. This leads to misjudgments of the actual stress state at different stages by technical personnel, affecting the issuance of subsequent linear formwork erection commands and hindering proper adjustments to the continuous beam modeling system. Therefore, the difficulty in setting up measurement auxiliary tools, slow alignment speed, and low accuracy have always been problems plaguing surveyors. Ensuring the prism rods are always precisely centered and leveled to improve measurement efficiency and guarantee data accuracy has become a crucial aspect of continuous beam monitoring. Alignment accuracy directly affects the quality of field measurement data; large errors exceeding specifications can lead to rework or quality accidents, causing irreparable losses to the project. According to the "Engineering Surveying Standards", the centering deviation of instruments and prisms should not exceed 2mm.

[0004] Currently, the traditional construction method mainly involves surveyors manually intervening to maintain the centering of the prism rod. While setting up the prism rod, they signal the observers to observe in a timely manner. The main drawbacks of this construction method are that it is greatly affected by environmental factors and the data is greatly affected by human factors. In complex environments, the centering and leveling of the prism rod is slow, the work efficiency is low, and the centering accuracy is low. To address this, we propose a portable measurement and monitoring auxiliary device. Utility Model Content

[0005] The purpose of this invention is to provide a portable measurement and monitoring auxiliary device to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable measurement and monitoring auxiliary device, comprising a prism rod, a support rod, and a mounting base. The support rod is movably connected to the middle two sides of the prism rod via connectors. A rotating ring is movably connected to the bottom outer periphery of the support rod via bearings.

A locking block is slidably disposed inside the locking block groove. A locking spring is provided at the end of the locking block that extends into the locking block groove. A mounting base is sleeved on the bottom of the support rod. A trapezoidal groove is provided at the bottom of the mounting base. Slots are provided on both sides of the top of the mounting base. A locking groove is provided on the side of the slot corresponding to the locking block at the bottom of the slot.

[0007] Preferably, the card slot passes laterally through the housing of the card holder and communicates with the outside. The inside of the card slot is provided with a pressing block extending to the outside. A push block is fixedly connected to one side of the pressing block inside the card slot.

[0008] Preferably, the inner walls on both sides of the card slot are provided with second limiting grooves, and the two ends of the extrusion block are fixedly installed with second limiting blocks on the side near the push block. The second limiting blocks extend into the interior of the second limiting groove and are slidably connected to its inner wall.

[0009] Preferably, a reset spring is provided inside the second limiting groove, and the two ends of the reset spring are fixedly connected to the inner walls of the second limiting block and the second limiting groove, respectively.

[0010] Preferably, the inner walls on both sides of the card slot are provided with first limiting grooves, and the two ends of the card are fixedly installed with first limiting blocks, which extend into the interior of the first limiting groove and are slidably connected thereto.

[0011] Preferably, a through groove is provided at the top center of the card holder, the inner diameter of the through groove corresponds to the diameter of the support rod, and the through groove connects to the bottom of the card holder.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By installing a clamp at the bottom of the support rod using a snap-fit ​​method, the stability of the connection between the clamp and the support rod is ensured. Furthermore, by setting a trapezoidal groove at the bottom of the clamp, a temporary and reliable connection with the reinforcing steel is made using the trapezoidal groove, thereby improving the stability of the prism rod. This facilitates the smooth commencement of measurement work by the staff, reduces the impact of adverse factors, and increases work efficiency.

[0014] 2. By connecting the rotating ring to the support rod via bearings, after the mounting bracket and the rotating ring are snapped together, the trapezoidal groove at the bottom of the mounting bracket can be adjusted according to the steel bar trajectory at the actual measurement position. This allows the mounting bracket to temporarily and reliably connect with the steel bar using the trapezoidal groove at the bottom, thereby achieving centering and leveling and improving the applicability of the equipment.

[0021] Please see Figure 1-4 This utility model provides a portable measurement and monitoring auxiliary device technical solution: including a prism rod 1, a support rod 3, and a mounting base 12. The middle end of the prism rod 1 is movably connected to the support rod 3 on both sides through a connector 2. The bottom outer periphery of the support rod 3 is movably connected to a rotating ring 4 through a bearing 5. Insert plates 6 are fixedly installed on both sides of the bottom of the rotating ring 4. A locking block groove 7 is opened on the side of the two insert plates 6 that are far apart from each other. A locking block 9 is slidably arranged inside the locking block groove 7. A locking spring 11 is provided at one end of the locking block 9 that extends into the locking block groove 7. The bottom of the support rod 3 is sleeved with a mounting base 12. A trapezoidal slot 14 is opened at the bottom of the mounting base 12. Slots 15 are opened on both sides of the top of the mounting base 12. A slot 16 is opened on the bottom side of the slot 15 corresponding to the side of the locking block 9.

[0022] Specifically, the card slot 16 passes horizontally through the housing of the card holder 12 and communicates with the outside. The inside of the card slot 16 is provided with a pressing block 17 extending to the outside. The pressing block 17 is fixedly connected to a push block 18 on one side inside the card slot 16.

[0023] Specifically, the inner walls on both sides of the card slot 16 are provided with second limiting grooves 19, and the two ends of the extrusion block 17 are fixedly installed with second limiting blocks 20 on the side near the push block 18. The second limiting blocks 20 extend into the interior of the second limiting groove 19 and slide in connection with its inner wall.

[0024] Specifically, a reset spring 21 is provided inside the second limiting groove 19, and the two ends of the reset spring 21 are fixedly connected to the inner walls of the second limiting block 20 and the second limiting groove 19, respectively.

[0025] Specifically, the inner walls on both sides of the card slot 7 are provided with first limiting grooves 8, and the two ends of the card 9 are fixedly installed with first limiting blocks 10. The first limiting blocks 10 extend into the interior of the first limiting grooves 8 and are slidably connected to them.

[0026] Specifically, a through groove 13 is provided at the top center of the card holder 12. The inner diameter of the through groove 13 corresponds to the diameter of the support rod 3, and the through groove 13 connects to the bottom of the card holder 12.

[0027] In this embodiment, during operation, the card holder 12 is first sleeved onto the bottom of the support rod 3, allowing the bottom of the support rod 3 to pass through the through groove 13. The slot 15 is then aligned with the insert plates 6 on both sides of the bottom of the rotating ring 4, allowing the insert plates 6 to be inserted into the slot 15. Under the action of the snap-fit ​​spring 11, the snap-fit ​​block 9 is pushed into the slot 16, ensuring a reliable connection between the card holder 12 and the support rod 3, thus completing the initial assembly.
