Description

Technical Field

[0001] The utility model relates to a monitoring component for effective prestress under an anchor, belonging to the technical field of prestress detectors under an anchor. Background Technique

[0002] Monitoring the effective prestress under an anchor is an important link in bridge engineering, which directly affects the bearing capacity and service life of the bridge structure. The effective prestress under an anchor refers to the prestress remaining under the working anchor after the prestressed tendon is tensioned and anchored. This parameter is crucial for ensuring the safety and stability of the bridge.

[0003] Selecting appropriate monitoring equipment is crucial for ensuring the accuracy of detecting the effective prestress under an anchor. Currently, there are various types of prestress detectors under an anchor on the market. These devices are usually equipped with high-precision pressure sensors and data processing systems. By pre-tensioning steel bars or steel strands, etc., a certain stress state is given to them before they bear external forces, which is a technical measure to improve the bearing capacity and crack resistance of the structure. The accurate detection of the prestress under an anchor is to ensure the safety and reliability of the structure. It can accurately measure the prestress magnitude under the anchor and detect the unevenness of the same bundle and the unevenness of the same cross-section, etc., providing important data for the construction and maintenance of prestressed concrete structures such as bridges and tunnels. Since prestress monitoring is mostly carried out at the construction site, and the construction site is relatively messy, building materials, tools and other items are randomly stacked, resulting in chaos in the construction site order and increasing the risk of falling objects from height. The existing detectors lack corresponding protective devices, and may directly hit the monitoring equipment when there is a falling object from height, causing physical damage to the equipment and possibly reducing the accuracy of the internal sensors of the equipment, thus affecting the measurement results of the prestress and reducing the service life of the equipment. As a professional device for detecting the prestress under an anchor in bridges and other structures, the accuracy and stability of the prestress detector under an anchor are crucial for ensuring the structural safety. Therefore, the damage that may be caused by falling objects from height cannot be ignored.

[0004] Therefore, a monitoring component for effective prestress under an anchor is proposed. Content of the Utility Model

[0006] The technical solution of the utility model is realized as follows: An effective prestress monitoring component under the anchor includes a bottom plate. A prestress monitoring device is fixedly connected to the top of the bottom plate. A protection mechanism is arranged on the top of the prestress monitoring device. The protection mechanism includes a shock-absorbing plate. A notch is opened in the middle of the top of the shock-absorbing plate. A guide rod is fixedly connected to the inside of the notch.

Elastic metal sheets are fixedly connected to the tops of the two sliding sleeves. Shock-absorbing springs are fixedly connected to the outside of the two sliding sleeves. The outside of the two shock-absorbing springs is fixedly connected to the inside of the notch. A buffer plate is fixedly connected to the top of the elastic metal sheet. Spring dampers are fixedly connected to the four peripheries of the bottom of the buffer plate.

[0007] Further preferably, a disassembly mechanism is arranged on the outside of the protection mechanism. The disassembly mechanism includes fixing blocks. The fixing blocks are fixedly connected to the front and rear sides of the bottom of the shock-absorbing plate. Jack holes are opened on the left and right sides of the two fixing blocks. Device boxes are fixedly connected to the left and right ends of the front and rear sides of the bottom plate. Return springs are fixedly connected to the outside of the inner cavities of the four device boxes. Moving blocks are fixedly connected to the inner sides of the four return springs. Plug rods are fixedly connected to the inner sides of the four moving blocks. Pull rods are fixedly connected to the front sides of the four moving blocks.

[0008] Further preferably, sliders are fixedly connected to the bottoms of the four moving blocks. Sliding grooves are opened at the bottoms of the inner cavities of the four device boxes. The bottoms of the four sliders are slidably connected to the inner cavities of the four sliding grooves.

[0009] Further preferably, pull grooves are opened on the front sides of the four device boxes. The four pull rods penetrate through the inner cavities of the four pull grooves and extend to the outside of the four device boxes.

[0010] Further preferably, guide blocks are fixedly connected to the bottoms of the two sliding sleeves. A guide groove is opened at the bottom of the notch. The bottoms of the two guide blocks are slidably connected to the inner cavity of the guide groove.

[0014] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0015] 1. The utility model monitors prestress through a prestress monitoring device. When the buffer plate is impacted by falling objects from a high altitude, the downward impact force of the buffer plate squeezes the spring damper and drives the elastic metal sheet to move downward, so that the elastic metal sheet drives the sliding sleeve to slide on both sides of the guide rod, stretching and squeezing the tension spring and the shock-absorbing spring, causing the tension spring and the shock-absorbing spring to deform and buffer them, thereby reducing the impact degree of the prestress monitoring device caused by falling objects from a high altitude, reducing the loss of the prestress monitoring device caused by falling objects from a high altitude, and increasing the service life of the equipment.

[0016] 2. The utility model provides a disassembly mechanism. When the prestressed monitoring device completes the monitoring work, the pull rod is pulled outward so that the pull rod drives the moving block to squeeze the reset spring, causing the reset spring to deform and causing the insertion rod to separate from the inner cavity of the socket, so that the protective mechanism can be disassembled, simplifying the tediousness of installation and disassembly. By providing a slider and a slide groove, the stability of the moving block during movement can be improved. By providing a pull groove, the movement of the pull rod can be limited to avoid the pull rod from deviating during movement. By providing a guide block and a guide groove, the stability of the sliding sleeve during movement can be improved. By providing a limiting hole, the movement of the device box can be limited to avoid the device box from deviating during movement. By providing a moving wheel, the overall equipment can be easily transferred. By providing a handle, the overall equipment can be easily hoisted or carried.

The prestress is monitored by the prestress monitoring device 3. When the buffer plate 208 is impacted by falling objects from a height, the downward impact force of the buffer plate 208 squeezes the spring damper 209 and drives the elastic metal sheet 206 to move downwards, causing the elastic metal sheet 206 to drive the sliding sleeve 204 to slide on both sides of the guide rod 203, stretching and squeezing the tension spring 205 and the shock-absorbing spring 207, deforming the tension spring 205 and the shock-absorbing spring 207 to buffer it, reducing the impact degree on the prestress monitoring device 3 caused by falling objects from a height, reducing the loss caused by falling objects from a height to the prestress monitoring device 3, and improving the service life of the device. When the prestress monitoring device 3 completes the monitoring work, pull the pull rod 407 outwards, so that the pull rod 407 drives the moving block 405 to squeeze the return spring 404, causing the return spring 404 to deform, and the insertion rod 406 to disengage from the inner cavity of the insertion hole 402, and the protection mechanism 2 can be disassembled, simplifying the complexity of installation and disassembly.
