[0048] The base 62 is symmetrically provided with two groups of guide blocks 64 with their own central axes as the reference.

[0049] Please refer to Figure 1 In the embodiment, the installation position of the monitoring mechanism 6 is not limited to the position as Figure 1 The monitoring mechanism 6 at the position can monitor the real-time deviation of the tower crane by means of the left distribution beam assembly 3, and the monitoring mechanism 6 can also be installed at the right side of the No. 0 block and monitor the real-time deviation of the tower crane by means of the right distribution beam assembly 3. Similarly, the monitoring mechanism 6 can also monitor the real-time deviation of the tower crane by means of the two main beam assemblies 1, and only the installation position of the monitoring mechanism 6 needs to be changed.

[0050] Further, the monitoring assembly 65 is a symmetrical structure, the guide block 64 is provided with a guide surface 641 on the side close to the monitoring assembly 65, the guide surface 641 is an arc surface and five groups of monitoring protrusions 642 are arranged on the guide surface 641.

[0051] Further, the monitoring assembly 65 comprises a shell 651, a fitting piece 652, a vertical rod 653, a monitoring piece 654, a monitoring spring 655, a pressure sensor 656 and a warning component 657.

[0052] In the embodiment, the warning component 657 can be a strong light flashing warning mode, a harsh alarm warning mode, or a non-polluting medium spraying warning mode, and the best warning mode can be selected according to the specific construction environment and construction conditions.

[0053] The shell 651 with the fitting piece 652 connected outside is rotatably connected to the rotating seat 63, the vertical rod 653 is installed inside the shell 651, the monitoring spring 655 is sleeved outside the vertical rod 653, the monitoring piece 654 is slidably sleeved on the vertical rod 653, the upper end of the monitoring spring 655 is connected with the lower end of the monitoring piece 654, the pressure sensor 656 is installed inside the shell 651 at the position of the lower end of the vertical rod 653, and the warning component 657 is installed inside the shell 651 at the position of the lower end of the pressure sensor 656.

[0054] The pressure sensor 656 and the warning component 657 are connected through a transmission line.

[0055] Please refer to Figure 2 , Figure 3As shown, as a preferred embodiment, the monitoring mechanism 6 is shown as a Figure 1 The working process of the monitoring mechanism 6 is described in detail as follows: when the monitoring mechanism 6 is in a stable monitoring state, the fitting part 652 is tightly attached to one end surface of the distribution beam assembly 3. When the tower crane deviates (specifically, the deviation from the vertical direction) during the construction, the distribution beam assembly 3 tightly attached to the fitting part 652 will drive the shell 651 to rotate around the rotating seat 63. If the deviation is to the right, the shell 651 will rotate clockwise. If the deviation is to the left, the shell 651 will rotate counterclockwise.

[0056] The working process of the monitoring mechanism 6 is described in detail as follows: when the monitoring mechanism 6 is in a stable monitoring state, the fitting part 652 is tightly attached to one end surface of the distribution beam assembly 3. When the tower crane deviates (specifically, the deviation from the vertical direction) during the construction, the distribution beam assembly 3 tightly attached to the fitting part 652 will drive the shell 651 to rotate around the rotating seat 63. If the deviation is to the right, the shell 651 will rotate clockwise. If the deviation is to the left, the shell 651 will rotate counterclockwise.

[0057] Since the arc center of the guide surface 641 is not concentric with the rotating center of the monitoring part 654, the pressure of the monitoring spring 655 on the pressure sensor 656 will gradually increase during the rotation of the monitoring part 654. Since the guide surface 641 is provided with five groups of monitoring protrusions 642, the contact head will pass through the five groups of monitoring protrusions 642 in sequence during the rotation of the monitoring part 654. The pressure of the monitoring spring 655 on the pressure sensor 656 will gradually increase, and five times of sudden changes in the measured value will be generated.

[0058] Please refer to Figure 3 , Figure 4 As shown, the measured value information obtained by the pressure sensor 656 will be transmitted to the warning component 657 through the transmission line, and the warning component 657 will start to warn. When the pressure sensor 656 measures one sudden change in the measured value, the warning component 657 will issue a first warning level. Similarly, the strongest warning level is a fifth warning level. The present application can monitor the deviation of the tower crane in real time and issue different warning levels according to different deviation degrees. The working personnel can determine the deviation degree of the tower crane according to the warning level issued by the warning component 657 and the pressure value measured by the pressure sensor 656 (the value refers to the degree of increase during the gradual increase of the pressure), so as to make corresponding treatment. If the warning level is low, the tower crane and the steel platform can be reinforced and straightened. If the warning level is high, the personnel in the construction site need to be evacuated to ensure the safety of life.

[0059] Preferably, in addition to the above embodiments, the sizes of the five groups of monitoring protrusions 642 can also be set to gradually increase, at which time the sudden change in each measurement value measured by the pressure sensor 656 is gradually increasing, and the specific value of the sudden change in each measurement value is obtained through prior testing, and the basis for the final warning component 657 to issue a pre-warning level becomes more simplified, that is, different levels of pre-warning are made for different sudden change values, which is more convenient for the staff to know the deviation of the tower crane at the first time.
