Description

Technical Field

[0001] The utility model relates to the field of Bailey bridges, in particular to a Bailey bridge convenient for high-altitude installation. Background Technique

[0002] The Bailey bridge convenient for high-altitude installation, also known as Bailey sheets, Bailey beams or trusses, is a quick-erection support tool composed of components such as trusses, connecting pins and safety pins, and strengthening chord bars. It was originally mostly used for quickly erecting bridges. Due to its strong bearing capacity, good structural rigidity, long fatigue life and adjustable support system, it is now widely used in the construction of large-span platforms such as highways, bridges, and factories. In the field of high-altitude large-span building construction, the Bailey bridge provides a stable operation platform for construction workers, greatly facilitating high-altitude operations. The stress sensors on traditional Bailey bridges mainly use contact-type fixed-point sensors. However, this method has some obvious defects. Since the sensors are usually installed at fixed positions, only the stress changes at these points can be measured, and the overall stress distribution of the Bailey bridge cannot be comprehensively reflected. At the same time, the limited measurement points result in relatively discrete data, which may not accurately capture the stress concentration areas or potential weak points. In addition, the installation process of contact-type sensors is complex, and frequent maintenance and calibration are required during long-term use, increasing the difficulty and cost of use. At this time, a new type of Bailey bridge convenient for high-altitude installation is needed to solve this problem. Content of the Utility Model

[0012] Furthermore, the output end of the electric push rod penetrates through the mounting seat and extends into the interior of the movable groove, and the output end of the electric push rod is fixedly connected with a mounting rod.

[0013] By adopting the above technical solutions, the stability and accuracy of the electric push rod when pushing the mounting rod to move up and down are ensured, so as to ensure that the deformation layer and the deformation sheet can be accurately attached to the Bailey truss, providing an important guarantee for obtaining accurate monitoring data.

[0014] Furthermore, a mounting plate is fixedly connected to the bottom of the mounting rod, and the electric push rod is used to promote the mounting plate to move up and down.

[0015] By adopting the above technical solutions, the contact distance between the mounting plate and the deformation layer and the deformation sheet thereon and the Bailey truss can be accurately adjusted, ensuring that the sensor can accurately capture the deformation data of the Bailey truss and improving the measurement accuracy.

[0016] Furthermore, a deformation layer is arranged at the bottom of the mounting plate, a deformation sheet is arranged at the bottom of the deformation layer, the deformation layer is used to provide the amount of deformation, and the deformation sheet is used to monitor the stress of the Bailey truss.

[0017] By adopting the above technical solutions, the deformation layer can deform correspondingly with the deformation of the Bailey truss, and this deformation is accurately captured by the deformation sheet and converted into an electric signal, so as to realize the real-time monitoring of the stress of the Bailey truss.

[0018] Furthermore, multiple sets of the frame body are provided, and splicing pieces and splicing blocks are respectively arranged at both ends of the multiple sets of the frame body.

[0024] In summary, the utility model mainly has the following beneficial effects:

[0025] 1. In the utility model, a sensing mechanism, a mounting frame, side grooves, a mounting seat, a first motor, a gear, and a rack are provided.

In addition, the first motor drives the gear to drive the two racks to move, and then through the movement of the fixing plate, the stable clamping of the sensing mechanism on the frame body is realized. This mechanism not only facilitates the quick installation and disassembly of the sensing mechanism but also significantly improves the operation efficiency. At the same time, the fixing plate connects the rack and the second motor, which not only plays a supporting role but also ensures the stability of the sensing mechanism. The second motor drives the rotating wheels to move flexibly in the side grooves and engage and slide with the U-shaped grooves of the frame body, thus increasing the lateral movement range and flexibility of the sensing mechanism.

The mounting rod stably connects the electric push rod and the mounting plate, ensuring the stability and reliability of the sensing mechanism during the lifting process. The mounting plate provides a stable reference surface for the sensing mechanism, and its stability and flatness have an important impact on the accuracy of stress measurement. Through precise control of the electric push rod, the mounting plate can perform stress measurement at the optimal position, thereby improving the measurement accuracy. The deformation layer directly contacts the Bailey truss, accurately measures its deformation, reflects the stress state of the Bailey truss, and at the same time combines with the strain gauge to convert the micro deformation into a measurable electrical signal, realizing precise stress monitoring. The electric push rod plays a key role in the sensing mechanism. It ensures that the deformation layer and the strain gauge can effectively press on the Bailey truss, improves the accuracy of stress measurement, and guarantees the stability and reliability of the sensing mechanism in various high-altitude installation environments. Therefore, the electric push rod is the core component to ensure sensing accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
