Description

Technical Field

[0001] This utility model belongs to the field of steel structure monitoring technology, and in particular relates to a vibration monitoring device for steel structure construction. Background Technology

[0002] In modern construction engineering, steel structures are widely used in the construction of various buildings due to their advantages such as high strength, light weight, and fast construction speed. Ensuring the stability and safety of the structure is crucial during its construction. To achieve this goal, introducing a vibration monitoring mechanism is essential. Vibration sensors are typically installed at each important connection point and inflection point of the steel structure to monitor the vibration frequency generated during construction in real time.

[0003] However, current vibration monitoring devices suffer from numerous problems. Firstly, existing devices rely excessively on connectors to secure sensors. In complex steel structure environments, such as confined spaces or structurally uniquely shaped areas, installing these connectors is extremely difficult, even impossible, significantly increasing the difficulty and time cost of sensor installation and severely impacting construction progress. Secondly, existing devices lack effective organization and routing planning for the wiring harnesses connecting sensors and control equipment. On construction sites, wiring harnesses are often haphazardly arranged, making them susceptible to damage from mechanical impacts and pulling during construction. Furthermore, troubleshooting and repair are extremely cumbersome in the event of a malfunction, greatly reducing the reliability and stability of the monitoring device.

[0004] Therefore, it is essential to invent a vibration monitoring device for steel structure construction. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a vibration monitoring device for steel structure construction, comprising a control box, a display, a data cable, a monitoring sensor, an extension bracket, a wire clip, a mounting platform, magnets, a turntable, a clamping arm, a screw, and a nut. The control box is equipped with a display and is connected to the monitoring sensor fixedly mounted on the mounting platform via the data cable. The data cable is mounted on a wire clip fixedly mounted on the extension bracket, one end of which is rotatably connected to the mounting platform. Two mirror-symmetrical magnets are disposed on the lower surface of the mounting platform. Turntables are rotatably mounted on both sides of the mounting platform, and a clamping arm is rotatably mounted on each turntable. The two clamping arms are passed through by the screw, and one end of the screw is tightened with the nut.

[0006] Preferably, the monitoring sensor is a vibration detection sensor, and the monitoring sensor and the magnet are mounted on two opposite surfaces of the mounting platform, with the magnet able to adhere to the steel structure plane.

[0007] Preferably, the mounting platform has a slot in the middle that allows the extension bracket to be rotatably installed, and the extension bracket is fixed to the steel beam of the steel structure by cable ties.

[0008] Preferably, the extension bracket has a plurality of wire clips arranged along its own axial direction, the wire clips being used to securely restrain the data cable.

[0009] Preferably, a turntable is rotatably mounted on both sides of the mounting platform, and the arm mounted on the turntable is an arc-shaped structure, with a through hole at one end of the arm allowing the screw to pass through.

[0010] Preferably, the two mirror-symmetrical clamping arms can securely fix the mounting platform to the cylindrical steel beam of the steel structure by means of the screw and nut, and the mounting platform is provided with an arc-shaped recess located between the two magnets.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention allows the monitoring sensor to be easily and quickly attached to the steel structure by setting two mirror-symmetrical magnets on the lower surface of the mounting platform. Compared with the traditional installation method that relies on complex connectors, it significantly simplifies the installation process, especially in some hard-to-operate locations, enabling rapid installation and greatly improving construction efficiency.

[0013] This utility model features two mirror-symmetrical clamping arms that, together with screws and nuts, can firmly fix the mounting platform onto the cylindrical steel beam of the steel structure. This design can adapt to steel beam structures of different shapes, providing a reliable fixing method for the monitoring device and ensuring that the monitoring sensor will not be displaced due to vibration or other factors during the steel structure construction process, thus guaranteeing the accuracy of the monitoring data.

[0014] This utility model features numerous wire clips arranged along its own axis on the extension bracket. Data cables are placed on these clips, allowing for orderly organization and preventing tangled wire bundles. This not only reduces the risk of data cables being damaged due to disorderly placement at the construction site but also facilitates quick troubleshooting and repair in case of malfunctions, improving the reliability and stability of the entire monitoring device.

[0015] In addition, the mounting platform of this utility model has a slot in the middle that allows the extension bracket to be rotated and installed. The extension bracket can be fixed to the steel beam of the steel structure by cable ties. The turntables on both sides of the mounting platform are rotated relative to each other, and the arc-shaped brackets are rotated and installed on the turntables. This allows the entire device to flexibly adapt to steel structure components of different angles and shapes, greatly enhancing the versatility and applicability of the device and meeting the diverse vibration monitoring needs of steel structure construction.

[0023] As attached Figure 1 To be continued Figure 3 As shown:

[0024] This utility model provides a vibration monitoring device for steel structure construction, including a control box 1, a display 2, a data cable 3, a monitoring sensor 4, an extension bracket 5, a wire buckle 6, a mounting platform 7, a magnet 8, a turntable 9, a clamping arm 10, a screw 11, and a nut 12. The control box 1 is equipped with a display 2, and the control box 1 is connected to the monitoring sensor 4 fixedly mounted on the mounting platform 7 via the data cable 3. The data cable 3 is placed on the wire buckle 6 fixedly mounted on the extension bracket 5, and one end of the extension bracket 5 is rotatably connected to the mounting platform 7. Two mirror-symmetrical magnets 8 are provided on the lower surface of the mounting platform 7. Turntables 9 are rotatably mounted on both sides of the mounting platform 7, and a clamping arm 10 is rotatably mounted on each turntable 9. The two clamping arms 10 are passed through by the screw 11, and the nut 12 is tightened at one end of the screw 11.

[0025] Furthermore, monitoring sensor 4 is a vibration detection sensor, whose main function is to accurately sense the vibration generated during the steel structure construction process and convert the vibration signal into an electrical signal for subsequent processing. Monitoring sensor 4 is installed on the upper surface of mounting platform 7, in a relative position to magnet 8 installed on the lower surface of mounting platform 7. Vibration detection sensor 4 can be a piezoelectric vibration sensor, which works based on the piezoelectric effect principle and features high sensitivity and fast response speed. During installation, it is securely fixed in the pre-set mounting slot of mounting platform 7 with screws, ensuring a tight fit between the sensor and mounting platform 7, and accurately receiving vibration information from the steel structure.

[0026] Furthermore, a specific slot is provided in the middle of the mounting platform 7. The size and shape of this slot are designed to fit one end of the extension bracket 5, allowing the extension bracket 5 to be installed in the slot in a rotatable manner. The extension bracket 5 can be made of aluminum alloy, which is lightweight and high-strength, facilitating installation and operation on the construction site. During actual installation, the extension bracket 5 is fixed to the steel beam of the steel structure with cable ties made of high-strength nylon, which has good toughness and wear resistance, ensuring that the extension bracket 5 is stably fixed to the steel beam without damaging the surface of the steel beam. The extension bracket 5 can rotate around the slot on the mounting platform 7 at a certain angle to adapt to the arrangement of steel beams at different angles, improving the installation flexibility of the device.

[0027] Furthermore, numerous cable clips 6 are evenly and densely arranged along the axial direction of the extension bracket 5. The cable clips 6 are made of rubber, a material with good flexibility and anti-slip properties, effectively and firmly restraining the data cable 3. The data cable 3 is mainly used to transmit the vibration signals collected by the monitoring sensor 4 and connect them to the control box. The cable clip 6 is designed in a semi-circular ring shape, with its inner diameter slightly smaller than the outer diameter of the data cable 3. When the data cable 3 is placed inside the cable clip 6, the cable clip 6 will tightly wrap around the data cable 3 due to its elasticity, preventing the data cable 3 from shaking or shifting on the extension bracket 5. The spacing between each pair of adjacent cable clips 6 is reasonably set according to the length of the data cable 3 and actual installation requirements, ensuring that the data cable 3 can be neatly and orderly routed along the extension bracket 5.

[0028] Furthermore, turntables 9 are rotatably mounted on opposite sides of the mounting platform 7. The turntables 9 are connected to the mounting platform 7 via a rotating shaft made of stainless steel, which possesses high strength and corrosion resistance, ensuring the stability of the turntables 9 during frequent rotation. The rotatably mounted clamping arm 10 on the turntable 9 is designed with an arc-shaped structure, which better conforms to the outer surface of the cylindrical steel beam of the steel structure. The clamping arm 10 can be made of Q235 steel, forged and heat-treated to give it sufficient strength and toughness. One end of the clamping arm 10 has a through hole allowing a screw 11 to pass through; the diameter of this through hole matches the outer diameter of the screw 11, ensuring smooth passage. The clamping arm 10 can rotate around the turntable 9 to adjust its contact angle with the steel beam, improving the firmness of the fixation.

[0029] Furthermore, the two mirror-symmetrical clamping arms 10 securely fix the mounting platform 7 to the cylindrical steel beam of the steel structure via screws 11 and nuts 12. Both screws 11 and nuts 12 are made of high-strength carbon steel and have undergone surface galvanizing treatment, providing excellent rust resistance. The mounting platform 7 has an arc-shaped recess located between two magnets 8. When the clamping arms 10 grip the cylindrical steel beam, the arc-shaped recess on the mounting platform 7 can better conform to the surface of the steel beam, further enhancing the stability of the installation. During installation, the two clamping arms 10 are first rotated around the turntable 9 to a suitable angle so that they fit against the surface of the steel beam. Then, the screws 11 are passed through the through holes on the two clamping arms 10, and finally, the nuts 12 are tightened. The tightening force generated by the cooperation of the screws 11 and nuts 12 firmly fixes the clamping arms 10 to the steel beam, thus achieving a stable installation of the mounting platform 7.

[0030] The working principle is as follows: First, after the bottom of the steel structure is completed, the control box 1 is fixedly installed at the bottom of the steel structure using a bracket. This bracket can be made of angle steel and is firmly fixed to the foundation surface at the bottom of the steel structure by welding or bolting, ensuring that the control box 1 is installed firmly and stably. Continue to build the steel structure. When it reaches an important connection point or inflection point, begin to install the key parts of the vibration monitoring device.

[0031] At this point, the installation method is selected according to the requirements. If there is a flat surface at the connection point or inflection point, the mounting platform 7 can be directly attached to the steel structure surface by the magnet 8 installed on the mounting platform 7, thus fixing the mounting platform 7. The magnet 8 is made of neodymium iron boron strong magnetic material, which has a strong attraction force and can ensure the stability of the mounting platform 7 when placed. If the installation position is a cylindrical steel beam, the turntable 9 and the clamping arms 10 on both sides of the mounting platform 7 can be used for fixation. Rotate the two clamping arms 10 around the turntable 9 to a suitable angle so that they fit against the surface of the cylindrical steel beam. The turntable 9 is connected to the mounting platform 7 through a stainless steel rotating shaft, which can ensure that the clamping arms 10 can rotate flexibly. Then, the screw 11 is passed through the pre-drilled through holes on the two clamping arms 10, and finally the nut 12 is tightened. The cooperation of the screw 11 and the nut 12 generates a tightening force, which firmly fixes the clamping arms 10 to the steel beam, thus achieving a stable installation of the mounting platform 7 on the cylindrical steel beam. The arc-shaped recess on the mounting platform 7, located between the two magnets 8, can better fit with the surface of the steel beam when the arm 10 is fixed, further enhancing the installation stability.

[0032] After the mounting platform 7 is installed, the extension bracket 5 can rotate around the slot at a certain angle to accommodate steel beam arrangements at different angles. In actual installation, high-strength nylon cable ties are used to fix the extension bracket 5 to the steel beams of the steel structure. The good toughness and wear resistance of the cable ties ensure that the extension bracket 5 is stably fixed without damaging the surface of the steel beams.

[0033] Next, arrange the data cable 3. Place the data cable 3 inside the cable clip 6. The cable clip 6, due to its elasticity, tightly wraps around the data cable 3 to prevent it from shaking or shifting. The spacing between two adjacent cable clips 6 should be set reasonably according to the length of the data cable 3 and the actual installation requirements to ensure that the data cable 3 can be neatly and orderly routed along the extension bracket 5.

[0034] Finally, install monitoring sensor 4. Monitoring sensor 4 is a vibration detection sensor, specifically a piezoelectric vibration sensor, which works based on the piezoelectric effect principle and has high sensitivity and fast response speed. It is securely fixed in the pre-set mounting slot of mounting platform 7 using screws, ensuring a tight fit to the platform 7 to accurately receive vibration information from the steel structure.

[0035] During the subsequent construction of the steel structure, monitoring sensor 4 detects the vibration generated by the steel structure in real time and converts the vibration signal into an electrical signal. The electrical signal is transmitted to control box 1 via data cable 3, where control box 1 processes and analyzes the signal. The processed signal data is then transmitted to display on monitor 2, allowing construction personnel to intuitively understand the vibration during the steel structure construction process. If any abnormal vibration occurs, timely measures can be taken to ensure the smooth progress of the steel structure construction and structural safety.

[0036] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
