Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a steel truss beam elevation control device. Background Technology

[0002] Large-span steel structures, with their superior spatial performance and aesthetic appeal, are widely used in numerous large-scale building projects such as stadiums, exhibition halls, and large factories. During the construction of large-span steel structures, the elevation control of the steel truss beams is crucial, as its accuracy directly affects the safety of the entire structure and the final construction quality.

[0003] Currently, traditional methods dominate the work of adjusting the elevation of steel truss girders. Construction workers mainly rely on manual measurement using total stations or levels, and then adjust the elevation of the steel truss girders by manually adjusting shims or jacks.

[0004] However, traditional methods suffer from several drawbacks. First, manual measurement is highly susceptible to the influence of the surveyor's skill level and environmental factors (such as temperature, lighting, and wind), leading to data inaccuracies and failing to meet the high-precision elevation control requirements of large-span steel structures. Second, manually adjusting shims or jacks is cumbersome and labor-intensive. Each adjustment requires repeated tool operation by construction workers, which is not only difficult but also inefficient for large steel trusses. In conclusion, traditional methods rely almost entirely on manual operation, lacking automated measurement and adjustment mechanisms, and are unable to achieve real-time, dynamic elevation adjustment, making them ill-suited to the demands of modern construction for efficient and precise operations. Utility Model Content

[0030] See Figure 1 The steel truss beam elevation control device provided in this embodiment of the present invention includes a monitoring component 1 and an adjustment component 2. The monitoring component 1 is detachably connected to the steel truss beam 100 to be measured and is used to monitor the actual elevation of the steel truss beam 100 and generate a feedback signal based on the actual elevation. The adjustment component 2 includes a controller 21 and a lifting mechanism 22. The lifting mechanism 22 is detachably mounted at the bottom of the steel truss beam 100 to be measured. The controller 21 is signal-connected to the lifting mechanism 22 and is used to receive the feedback signal and control the lifting mechanism 22 to move the steel truss beam 100 to be measured vertically based on the feedback signal, thereby adjusting the actual elevation of the steel truss beam 100 to be measured.

[0031] The steel truss elevation control device proposed in this utility model is detachably connected to the steel truss 100 to be measured via a monitoring component 1. This allows for flexible installation and removal on different steel truss 100s and enables its widespread application in various steel truss elevation monitoring scenarios, demonstrating high versatility. The monitoring component 1 can monitor the actual elevation of the steel truss 100 in real time and generate feedback signals, providing accurate data for subsequent adjustments. Compared to traditional manual measurement, this improves the accuracy and real-time performance of the measurement and effectively avoids data deviations caused by external factors in manual measurement. The lifting mechanism 22 in the adjustment component 2 is detachably mounted at the bottom of the steel truss 100 for easy installation and maintenance, and its installation position can be flexibly adjusted according to the specific location of the steel truss 100 and actual needs. The controller 21 receives feedback signals from the monitoring component 1 and controls the lifting mechanism 22 accordingly to move the steel truss beam vertically to adjust the actual elevation. This achieves automated adjustment, precise control of the steel truss beam elevation, and is simple and efficient to operate. It effectively avoids errors and cumbersome procedures associated with manual adjustment, improving the quality and efficiency of steel truss beam elevation adjustment during construction. In summary, the steel truss beam elevation control device proposed in this invention improves the convenience and efficiency of adjustment, reduces manpower input, and can quickly and accurately adjust the actual elevation of the steel truss beam 100 to the required position. Furthermore, the automated adjustment mechanism can achieve real-time, dynamic elevation adjustment, better meeting the requirements of high-precision elevation control in the construction of large-span steel structures, and improving construction quality and structural safety.

[0032] The specific structure of the steel truss elevation control device is described below.

[0033] Monitoring component 1 includes a hydrostatic level 11 and a data processor 12. The hydrostatic level 11 can be placed on top of the steel truss 100 to be measured and measures the actual elevation of the steel truss 100. The data processor 12 is electrically connected to the hydrostatic level 11 and is used to convert the actual elevation into a feedback signal. Placing the hydrostatic level 11 on top of the steel truss 100 allows for a more intuitive and accurate determination of the actual elevation. The actual elevation measured by the hydrostatic level 11 is usually presented as an analog signal or data in a specific format, which needs to be processed by the data processor 12. The data processor 12 converts this raw data into a feedback signal that the controller 21 can recognize and process. This conversion process achieves effective connection between the measurement data and subsequent adjustment and control. This ensures that the information obtained by monitoring component 1 can be accurately transmitted to the controller 21 of adjustment component 2, enabling the controller 21 to precisely control the lifting mechanism 22 to adjust the elevation of the steel truss based on the feedback signal.

[0034] The hydrostatic level 11 and the data processor 12 are both existing electrical equipment. Their working principles and specific structures will not be described in detail here.

[0035] Specifically, since the steel truss 100 to be measured may have uneven deformation in its extension direction, in this embodiment, two static levels 11 are provided. The two static levels 11 are arranged at intervals along the extension direction of the steel truss 100 to be measured. By cross-referencing and supplementing the data from the two measurement points, the actual elevation of the steel truss 100 to be measured can be more comprehensively and accurately reflected. If one of the static levels 11 has a measurement deviation due to local unevenness on the surface of the steel truss, the data from the other measurement point can be used as a reference. The data processor 12 can effectively reduce errors by comprehensively analyzing the data from the two measurement points, thereby obtaining the actual elevation of the steel truss 100 to be measured more accurately, providing a more reliable data basis for subsequent actual elevation adjustments. The two static levels 11 are connected to a single data processor 12, which reduces costs and improves the uniformity and coordination of data processing and transmission.

[0036] The steel truss elevation control device also includes a support assembly 3, which supports the lifting mechanism 22. The support assembly 3 provides an additional support foundation for the lifting mechanism 22, sharing some of the pressure from the steel truss 100 to be measured, reducing the load on the lifting mechanism 22, and making it more stable during operation.

[0037] Specifically, the support assembly 3 includes a support beam 31 extending in the horizontal direction and at least two support columns 32 extending in the vertical direction. The support beam 31 is mounted on the top of the support columns 32, and the lifting mechanism 22 is disposed on the support beam 31.

[0038] Furthermore, the height of the support column 32 is adjustable to accommodate the elevation adjustment needs of the steel truss beam 100 under different working conditions, specifications, and requirements, thereby improving the adaptability and versatility of the steel truss beam elevation control device.

[0039] Specifically, each support column 32 can be composed of two hollow metal tubes, one inner and one outer. The outer diameter of the inner tube is slightly smaller than the inner diameter of the outer tube, allowing the inner tube to fit tightly inside the outer tube and slide up and down relative to it. A corresponding locking mechanism is provided to restrict the movement of the inner and outer tubes, thereby adjusting the height of the support column 32. Alternatively, the support column 32 can be composed of multiple modular tube sections of the same specifications. Each tube section is a hollow cylinder with connecting structures at both ends. In use, operators select an appropriate number of tube sections to assemble according to the required elevation adjustment of the steel truss beam.

[0040] It is understandable that the specific implementation of the support column 32 is not limited here, as long as the height of the support column 32 can be adjusted.

[0041] The lifting mechanism 22 includes a drive unit 221 and a hydraulic jack 222. The controller 21 is connected to the drive unit 221 by signal. The controller 21 can send control commands to the drive unit 221, so that the drive unit 221 drives the output end of the hydraulic jack 222 to extend or retract, thereby driving the steel truss beam 100 to be measured to move in the vertical direction to adjust the actual elevation of the steel truss beam 100 to be measured.

[0042] Specifically, the drive unit 221 includes a servo motor 2211, a hydraulic pump, and a hydraulic cylinder 2212. The servo motor 2211 serves as a power source, driving the hydraulic pump to rotate, converting mechanical energy into hydraulic energy, and outputting controllable pressurized oil. By adjusting the speed and direction of the servo motor 2211, the flow rate and pressure of the hydraulic pump can be precisely controlled. The pressurized oil output by the hydraulic pump first enters the rodless chamber of the hydraulic cylinder 2212, pushing the piston of the hydraulic cylinder 2212 to move. The rod chamber of the hydraulic cylinder 2212 is connected to the lower chamber of the hydraulic jack 222 through a pipeline. Due to the difference in area between the rodless and rod chambers of the hydraulic cylinder 2212, the oil discharged from the hydraulic cylinder 2212 enters the hydraulic jack 222 at a higher pressure or a specific flow rate, achieving force amplification or speed regulation. The high-pressure oil discharged from the hydraulic cylinder 2212 enters the lower chamber of the hydraulic jack 222, pushing its piston upward and lifting the heavy object. When descent is required, the servo motor 2211 reverses, the hydraulic pump draws in oil, the hydraulic oil returns from the jack to the oil tank, and the piston resets under load.

[0043] When the hydraulic jack 222 is working, especially during start-up, stop-up or rapid lifting and lowering, its output end will generate an instantaneous impact force with the steel truss beam 100 to be tested.

[0044] Preferably, a damping layer is provided on the output end of the hydraulic jack 222. The damping layer can effectively buffer the impact force, avoid damage such as dents and deformation on the surface of the steel truss 100 under test due to direct impact, protect the integrity and surface quality of the steel truss 100 under test, and ensure that the steel truss 100 under test meets the construction requirements in terms of structure and appearance, thereby ensuring the safety and stability of the entire steel structure.

[0045] The damping layer can be made of rubber pads, silicone pads, spring pads, etc., which will not be elaborated here.

[0046] Furthermore, at least two hydraulic jacks 222 are provided, and multiple hydraulic jacks 222 are arranged at intervals along the length direction of the steel truss 100 to be tested. This allows the weight of the steel truss 100 to be tested to be evenly distributed to each support point, making the supporting force on the steel truss 100 to be tested more balanced during the elevation adjustment process, avoiding local stress concentration, maintaining the overall structural stability of the steel truss 100 to be tested, ensuring that the steel truss 100 to be tested does not twist or deform excessively during the elevation adjustment process, and guaranteeing the construction quality.

[0047] In other embodiments, the lifting mechanism 22 may also be a lead screw and nut pair, a telescopic motor, etc., which will not be described in detail here.

[0048] The controller 21 includes a wireless communication component 211, which is connected to an external device via a signal, and the external device can remotely control the controller 21.

[0049] Specifically, in this embodiment, the controller 21 is an industrial-grade programmable logic controller (PLC), which integrates a wireless communication module as a wireless communication component 211. This wireless communication module supports the Wi-Fi communication protocol and can establish a connection with a wireless router within the construction site, thereby accessing the local area network within the construction site. External devices are selected from tablets or smartphones, which interact with the wireless communication component 211 through a pre-defined program.

[0050] In addition, the controller 21 also includes a feedback component 212, which is used to upload data to the monitoring system and generate records. The feedback component 212 includes a data acquisition module, a data conversion module, and a data transmission module. The data acquisition module collects data in real time, such as the elevation of the steel truss beam, the pressure of the hydraulic jack 222, and the stress of the support column 32. The data conversion module converts the original analog signals into digital signals that the monitoring system can recognize and encodes them. The data transmission module uploads the encoded data to the monitoring system at the construction site control center via the signals. The monitoring system software parses, stores, and intuitively displays the data, and generates detailed records based on the uploaded data, storing them in chronological order in the server database for easy querying, analysis, and tracing of construction information.

[0051] The following describes the process of using the steel truss elevation control device.

[0052] First, before the steel truss beam 100 to be tested is erected, the static level 11 and the data processor 12 are installed at the set position of the steel truss beam 100 to be tested, and the hydraulic jack 222 is fixed to the top of the support beam 31. The bottom of the steel truss beam 100 to be tested is connected to the output end of the hydraulic jack 222.

[0053] Afterwards, the controller 21 starts a self-test after the design elevation value is input through an external device. After the self-test is completed, the monitoring component 1 is started and the static level 11 begins to measure the actual elevation of the 100 steel trusses to be measured. The data processor 12 converts the actual elevation into a feedback signal and transmits it to the controller 21.

[0054] The controller 21 has a pre-set database containing preset elevation ranges corresponding to the steel truss beam 100 to be measured. When the controller 21 receives a feedback signal, it determines whether the actual elevation of the steel truss beam 100 to be measured is within the preset elevation range. If the actual elevation of the steel truss beam 100 to be measured is within the preset elevation range, then the actual elevation of the steel truss beam 100 to be measured meets the requirements. If the actual elevation of the steel truss beam 100 to be measured is higher or lower than the preset elevation range, then the actual elevation of the steel truss beam 100 to be measured does not meet the requirements. At this time, the controller 21 outputs a control command based on the difference between the actual elevation of the steel truss beam 100 to be measured and the preset elevation range.

[0055] The controller 21 sends control commands to the servo motor 2211. By adjusting the speed and direction of the servo motor 2211, the flow and pressure of the hydraulic pump are controlled. Through the transmission of the hydraulic cylinder 2212, the output end of the hydraulic jack 222 is finally controlled to make corresponding adjustments, thereby driving the steel truss 100 under test to move in the vertical direction and thus adjusting the actual elevation of the steel truss 100 under test.

[0056] After the actual elevation of the steel truss beam 100 to be measured is adjusted, it is measured again by the static level 11, and it is determined whether the actual elevation of the steel truss beam 100 to be measured is within the preset elevation range. If the actual elevation of the steel truss beam 100 to be measured is within the preset elevation range, it indicates that the actual elevation of the steel truss beam 100 to be measured meets the requirements; otherwise, the hydraulic jack 222 is driven again for adjustment until the actual elevation of the steel truss beam 100 to be measured is within the preset elevation range, thus indicating that the actual elevation of the steel truss beam 100 to be measured meets the requirements.

[0057] After adjustment, the feedback component 212 uploads the data to the monitoring system and generates a record.
