Each of the stress-sensing plates 3 is connected to the control device 1. The top of the walking mechanism 2 is provided with an angle rotating device 5, the angle rotating device 5 is connected to a swing rod 6, the swing rod 6 is connected to a torque adjusting device 7, the torque adjusting device 7 includes an annular bracket 71 connected to the swing rod 6, the annular bracket 71 is rotatably connected to a rotating ring 72, both the annular bracket 71 and the rotating ring 72 have notches 73 for the hanging rod 4 to enter the inner side of the rotating ring 72, the inner side of the rotating ring 72 is provided with a plurality of telescopic top fixing rods 74, and the outer side of the annular bracket 71 is provided with a rotating mechanism 75 for driving the rotating ring 72 to rotate.

[0021] Specifically, the angle rotation device 5 includes a hinge seat 51 fixed to the top of the walking mechanism 2. The hinge seat 51 is rotatably connected to a rotary rod 52. The swing rod 6 is fixedly connected to the rotary rod 52. One end of the rotary rod 52 extends to the outside of the hinge seat 51 and is connected to a driven gear 53. The top of the walking mechanism 2 is provided with a first motor 54. The first motor 54 is connected to a driving gear 55. The driving gear 55 meshes with the driven gear 53.

[0022] Specifically, the outer wall of the annular support 71 is provided with a second motor 751, the output shaft of the second motor 751 is connected to a drive gear 752, and the outer wall of the rotating ring 72 has a toothed portion that meshes with the drive gear 752. The second motor 751 and the drive gear 752 constitute a rotating mechanism 75.

[0023] Specifically, the telescopic top fixing rod 74 is an electric push rod.

[0024] Specifically, the walking mechanism 2 includes a base plate 21 and movable wheels 22 rotatably connected to the bottom of the base plate 21. The movable wheels 22 are equipped with brake components, and the angle rotation device 5 is located on the top of the base plate 21. During the adjustment of the installation posture of the boom 4, wedge blocks or bricks can be placed on both sides of the movable wheels 22 to better prevent the walking mechanism 2 from moving.

[0025] Specifically, the control device 1 includes a data receiving module 11, an MCU 12, a first control module 13, and a second control module 14; the data receiving module 11, the first control module 13, and the second control module 14 are all connected to the MCU 12, the data receiving module 11 is connected to the stress sensing sheet 3, the first control module 13 is connected to the angle rotation device 5, and the second control module 14 is connected to the torque adjustment device 7.

[0026] The data receiving module 11 includes a first receiving module and a second receiving module. The first receiving module is used to receive data transmitted from the stress sensing sheet 3. The second receiving module is connected to a computer equipped with BIM modeling software and is used to import the BIM information of each hanger 4 into the control device 1 to determine the stress level of each hanger 4 after installation.

[0027] The first control module 13 is connected to the first motor 54, and the second control module 14 is connected to the second motor 751 and the electric push rod.

[0028] One specific application of this utility model is: In use, several stress-sensing plates 3 are attached to the corresponding suspension rods 4, and all stress-sensing plates 3 are connected to the port of the first receiving module.

[0030] The second control module 14 controls the extension of the electric push rod to fix the lifting rod 4 inside the rotating ring 72. According to the detection results of the stress sensing plate 3, when it is necessary to adjust the installation angle of the lifting rod 4, the first control module 13 drives the first motor 54 to start, which drives the rotary rod 52 to move through gear transmission, thereby changing the tilt angle of the swing rod 6. Since the lifting rod 4 is fixed inside the rotating ring 72, the angle of the lifting rod 4 also changes when the tilt angle of the swing rod 6 changes.

[0031] When it is necessary to adjust the torque of the boom 4, the second motor 751 drives the boom 4 to rotate around its own axis through gear meshing transmission, so as to achieve the purpose of adjusting the torque of the boom 4.

[0032] The advantages of this invention are as follows: Pre-set force parameters for the suspension rod 4 are imported through a BIM model, and the stress sensor 3 provides real-time feedback of the force data for the suspension rod 4, forming a closed-loop control. The angle and torque of the suspension rod 4 are adjusted using a motor-driven gear 752 transmission, meeting the ±20 mm axial tolerance requirement and overcoming the shortcomings of insufficient precision in manual adjustments. This device replaces traditional manual adjustments, reducing manpower and repetitive operations, and improving construction efficiency.
