Tightening each bolt manually is time-consuming and labor-intensive, resulting in low efficiency and extended construction periods. Moreover, manual operation makes it difficult to ensure that the tightening torque or axial force of each bolt is completely consistent, easily leading to some bolts being under-tightened or over-tightened, affecting the reliability of the connection. In addition, traditional tools and methods are inconvenient to operate in complex construction environments, such as at heights or in confined spaces, further increasing the difficulty and risk of construction.

[0041] like Figure 1 As shown, this embodiment provides a bolt group tightening construction device for tightening bolts within a bolt group, thereby ensuring the stability and safety of the steel structure. Specifically, the bolt group tightening construction device includes a support frame 1, a drive assembly (not shown), and multiple torque sleeves 2.

[0042] The torque sleeve 2 is adjustablely mounted on the support frame 1, which provides the torque sleeve 2 with an installation position and reliable support. Moving the support frame 1 allows for the movement of the device, facilitating the tightening of bolt groups in various construction environments without manual operation by construction personnel, thus reducing construction difficulty and risk. Multiple torque sleeves 2 can correspond one-to-one with multiple bolts in the bolt group to be tightened. The torque sleeve 2 is fitted over the bolts and can rotate around its own axis under the drive of the drive assembly, thereby achieving the tightening operation of the bolts in the bolt group. The drive assembly can drive multiple torque sleeves 2 to rotate simultaneously or separately with preset torques to tighten multiple bolts simultaneously or to tighten some of the bolts separately, effectively improving construction efficiency and precisely controlling the tightening torque to ensure tightening quality. In this embodiment, the drive assembly can be a motor; by controlling the output torque of the motor, the rotational torque of the torque sleeve 2 can be precisely controlled.

[0043] like Figure 1 As shown, the support frame 1 includes multiple first support rods 11 and multiple second support rods 12. The multiple first support rods 11 are parallel to each other and spaced apart along a first direction, while the multiple second support rods 12 are parallel to each other and spaced apart along a second direction, with the first and second directions forming an angle. Multiple torque sleeves 2 are adjustablely positioned on the first support rods 11 and / or the second support rods 12, corresponding one-to-one with the bolts in the bolt group to be tightened. In this embodiment, the first direction is perpendicular to the second direction, so the first support rods 11 are perpendicularly connected to the second support rods 12. This arrangement ensures the structural strength of the support frame 1 and improves the stability of the support.

[0044] Optionally, the spacing between the plurality of first support rods 11 is adjustable to adjust the distance between the plurality of first support rods 11 in a first direction according to the bolt distribution within the bolt group. Correspondingly, the spacing between the plurality of second support rods 12 is adjustable to adjust the distance between the plurality of second support rods 12 in a second direction according to the bolt distribution within the bolt group.

[0045] Furthermore, in this embodiment, the torque sleeve 2 is disposed at the connection point of the first support rod 11 and the second support rod 12. This arrangement ensures the stability and reliability of the torque sleeve 2 during installation.

[0046] Continue to refer to Figure 1 The bolt group tightening device also includes a torque detection device 3, with one torque detection device 3 connected to each torque sleeve 2 to detect the real-time torque of the torque sleeve 2. In this embodiment, the torque detection device 3 is a torque sensor, which has advantages such as high accuracy, fast frequency response, good reliability, and long service life.

[0047] Optionally, the bolt group tightening device further includes a controller 4, which is communicatively connected to both the drive assembly and the torque detection device 3. In this embodiment, the controller 4 can be a microcontroller or a PLC, etc. The controller 4 can control the output torque of the drive assembly based on the torque detection signal received from the torque detection device 3, thereby controlling the rotational torque of the torque sleeve 2. For example, when tightening a bolt group of a large steel beam, the controller 4 can, based on the distribution of bolts within the bolt group, first control the peripheral bolts to be initially tightened, and then gradually tighten them towards the center to ensure uniform stress on the steel beam and avoid deformation caused by improper tightening sequence.

[0048] Alternatively, the bolt group tightening device may also include an alarm component (not shown), which is communicatively connected to the controller 4. The controller 4 can also control the alarm component to sound an alarm based on the torque detection signal received from the torque detection device 3.

[0049] Specifically, the alarm component includes a sound generating device. When the torque detection device 3 detects an abnormal real-time torque value of the torque sleeve 2, the sound generating device emits an audible alarm. For example, the sound generating device can be a buzzer, which emits a loud and penetrating sound, facilitating timely detection by construction personnel.

[0050] More specifically, the alarm component also includes a light-generating device. When the torque detection device 3 detects an abnormal real-time torque value of the torque sleeve 2, the light-generating device illuminates. For example, the light-generating device may be a light-emitting diode (LED).

[0051] Alternatively, the bolt group tightening device may also include a display (not shown). The display is communicatively connected to the controller 4, which can also control the display to show the real-time torque of each torque sleeve 2 based on the torque detection signal received from the torque detection device 3, thereby facilitating the observation and judgment of the tightening status of each bolt by the construction personnel.

[0052] The operation steps of the bolt group fastening construction device provided in this embodiment are as follows:

[0053] First, device preparation and debugging: At the construction site, based on the steel structure construction drawings and the distribution of bolts within the bolt group, adjust the spacing of multiple first support rods 11 and multiple second support rods 12 to ensure that the torque sleeve 2 can accurately align with each bolt within the bolt group. Connect the controller 4 to the drive assembly and torque detection device 3, and debug them, inputting parameters such as the design torque value and tightening sequence. Simultaneously, calibrate the torque detection device 3 to ensure the accuracy of the measurement data.

[0054] Secondly, the construction operation is as follows: First, the bolts are installed into the bolt holes of the steel structure components. The controller 4 is activated, and multiple torque sleeves 2 rotate simultaneously, initially tightening the bolts according to the initial tightening torque and sequence. The initial tightening torque is set to 50%-70% of the design torque value to quickly and initially fix the bolts, ensuring a tight fit between the components. Second, a second tightening is performed, with the same torque as the initial tightening, further eliminating gaps between components and ensuring uniform bolt tightening. Third, a final tightening is performed, with the final tightening torque reaching the design torque value. The controller 4 precisely controls the torque of each bolt to ensure tightening quality. Throughout the construction process, the controller 4 collects data from the torque detection device 3 in real time, monitoring the tightening status of each bolt. If an abnormal real-time torque value is detected for any bolt, an alarm is immediately issued and automatic adjustments are made. Simultaneously, wireless communication technology is used to transmit construction data to a remote monitoring center in real time, facilitating real-time monitoring and management of construction progress and quality by construction personnel.

[0055] Finally, quality inspection and acceptance: After construction is completed, a portion of the bolts are randomly inspected using a torque testing tool to check whether their actual torque values ​​meet the design requirements. The number of bolts inspected follows relevant standards. If any bolt fails the inspection, it is either retightened or replaced until all bolts meet the tightening quality requirements, at which point acceptance is complete.

[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
