However, the control of the perpendicularity of prefabricated walls has always been a difficulty in the construction process. The traditional prefabricated wall perpendicularity detection method mainly relies on manual operation tools such as theodolites, plumb lines and rulers. Although these methods can meet the demand of perpendicularity detection to some extent, they have many limitations. For example, theodolite measurement requires accurate leveling, is greatly affected by the experience and skill level of the operator, and is prone to human error; the plumb line measurement is obviously affected by air flow, and can only detect the perpendicularity deviation, and cannot monitor the wall posture change in real time; the ruler measurement has high requirements for wall flatness, and the measurement range is limited.

[0003] In the prefabricated wall installation process, when the perpendicularity deviation is found, the traditional adjustment method is inefficient and lacks accuracy. For example, using manual adjustment support, it is difficult to accurately control the adjustment amount, and the operation process is cumbersome, consuming a lot of manpower and resources. Although there are some wall perpendicularity detection tools on the market, these tools mostly have the problems of low accuracy, complex operation, limited application range, etc. Especially when facing large prefabricated walls, the limitations of these tools are more obvious.

[0039] The rotating base frame is provided with a rotating circular groove matched with the detection base cylinder 210, and both ends of the detection base cylinder are provided with rotating shafts matched with the rotating circular groove; and the detection base cylinder 210 is located in the containing groove.

[0040] Preferably, two groups of rotating shafts 205 are arranged in the rotating circular groove and matched with the rotating shafts.

[0049] When the detection base cylinder 210 is provided with one set, the auxiliary support 500 is provided with two sets, and the two sets of auxiliary supports 500 are respectively located at the two ends of the detection base cylinder 210, and the corresponding adjustment downward assembly 700 is provided with two sets. This configuration can ensure that the wall is uniformly supported and adjusted on both sides, and is suitable for shorter or smaller walls. When the detection base cylinder 210 is provided with two sets, the auxiliary support 500 is provided with one set, and one set of auxiliary supports 500 is respectively located at the middle of the two sets of detection base cylinders 210, and the corresponding adjustment downward assembly 700 is provided with one set. This configuration is suitable for longer or larger walls, provides support and adjustment at a central point, and ensures the verticality and stability of the entire wall.

[0050] Specifically, the auxiliary support 500 serves as the basis for supporting and adjusting the downward moving assembly 700, and cooperates with the downward moving track 600 to ensure that the adjustment downward moving assembly 700 can move and adjust along the predetermined track. The auxiliary base frame 710 is vertically fixed on the auxiliary support 500 to provide support and movement guide for the auxiliary sliding frame 720. The auxiliary sliding frame 720 is in sliding cooperation with the auxiliary base frame 710 and performs telescopic movement under the control of the linear driving member 730. The linear driving member 730 is used to control the telescopic amount of the auxiliary sliding frame 720, so as to realize accurate control of the downward movement and fine adjustment of the wall. The linear driving member 730 can be a hydraulic cylinder, an air cylinder, an electric push rod or a lead screw, etc. The damping arm 740 connects the auxiliary sliding frame 720 and the moving roller 750, and is used to buffer the impact during the downward movement of the wall, so as to protect the wall and the device from being damaged.

[0053] Specifically, the horizontal and vertical clamping units 420 work together to firmly fix the vertical base plate 300 on the prefabricated wall, forming a stable measurement reference. This two-way clamping method effectively prevents the vertical base plate 300 from moving or shaking in any form during measurement and fine-tuning, thereby maximizing the accuracy and reliability of the measurement results.

[0054] First, move the device near the prefabricated wall by moving the wheels 111. Then, the operator uses the stable support frame 112 and the jacking hydraulic rod 113 to stably support the device on the ground. The jacking hydraulic rod 113 can be adjusted according to the ground conditions to ensure the levelness and stability of the device.

[0055] Perpendicularity measurement: use the clamping and fixing assembly 400 to firmly fix the vertical base plate 300 on the prefabricated wall. At this time, if the wall has a perpendicularity deviation, it will cause the telescopic carriage 220 to extend or retract accordingly. The telescopic amount of the telescopic carriage 220 will be intuitively displayed through the telescopic amount detection ruler 221 and the observation slide rail 211. The operator can judge the perpendicularity deviation of the wall by reading these data.

[0056] Auxiliary lowering and fine-tuning: If the position or attitude of the wall needs to be adjusted, the operator can accurately control the extension of the auxiliary carriage 720 through the linear drive 730. The movement of the auxiliary carriage 720 will drive the damping arm 740 and the moving roller 750 to slide along the lowering track 600, thereby achieving precise fine-tuning and auxiliary lowering of the wall. The design of the damping arm 740 can effectively buffer the impact during the lowering process, protecting the wall from damage.

[0057] Repeated detection and correction: After fine-tuning, the perpendicularity needs to be detected again to confirm the adjustment effect. The operator needs to repeatedly perform the perpendicularity detection and auxiliary lowering steps until the wall meets the expected perpendicularity requirement.

[0058] The technical features not described in the utility model can be realized by or using the prior art, and will not be described here again, of course, the above description is not a limitation of the utility model, and the utility model is not limited to the above examples, the changes, modifications, additions or replacements made by the ordinary skilled in the art within the essential scope of the utility model should also belong to the protection scope of the utility model.
