With the continuous increase of building height and the increasing complexity of construction environment, tower cranes face many safety hazards during operation. The inclination and deformation of tower cranes are one of the important factors that cause safety accidents. Once the tower crane is excessively inclined or deformed, it may cause serious accidents such as heavy object falling and tower collapse, which not only poses a great threat to the safety of personnel at the construction site, but also causes significant property loss and delay in construction period.

The infrared receiver shell 505 is fixedly installed at the bottom of the tower body 2 frame. The infrared receiver shell 505 is provided with the signal converter 506 on one side. The signal converter 506 is fixedly installed at the top of the bottom plate 1. The top of the signal converter 506 is electrically connected with the indicator lamp 507. The bottom of the infrared receiver shell 505 is fixedly installed with the first infrared receiving probe base 508. The first infrared receiving probe base 508 is fixedly sleeved with the second infrared receiving probe base 509 on one side. The second infrared receiving probe base 509 is fixedly sleeved with the third infrared receiving probe base 510 on one side. The top of the first infrared receiving probe base 508 is electrically connected with the first infrared receiving probe body 511.

The first infrared receiving probe body 511, the first infrared receiving probe matrix 512, and the third infrared receiving probe matrix 513 are all fixedly installed at the top of the infrared receiver shell 505.

[0025] The infrared emitting probe 503 is arranged directly above the first infrared receiving probe body 511. The alarm 504 is electrically connected with the signal converter 506.

[0026] The first infrared receiving probe matrix 512 and the third infrared receiving probe matrix 513 are both composed of a plurality of infrared signal receiving probes, and the plurality of infrared signal probes are arranged in a circular array with the first infrared receiving probe body 511 as the center.

[0027] The first infrared receiving probe base 508, the second infrared receiving probe base 509, and the third infrared receiving probe base 510 are all electrically connected with the signal converter 506.

[0029] It needs to be further explained that:

[0030] The infrared emission assembly 51 is installed at the top of the tower body 2 frame, including a power supply mounting plate 501, a power supply module 502, an infrared emission probe 503, and an alarm 504. The power supply mounting plate 501 is firmly fixed to provide support for the power supply module 502, and the power supply module 502 supplies power to the infrared emission probe 503, enabling it to continuously emit infrared signals. This infrared signal is the starting signal source of the entire monitoring mechanism, like a beam of light in the dark, laying the foundation for subsequent monitoring work. At the same time, the power supply module 502 is electrically connected with the alarm 504 installed on one side of the car 4, which can respond in time when the subsequent receiving assembly triggers an abnormal signal.

[0031] The infrared receiving and alarm assembly 52 is located at the bottom of the tower body 2 frame, including an infrared receiver housing 505, a signal converter 506, an indicator light 507, and different types of infrared receiving probe related components. The infrared receiver housing 505 protects the internal components. The first infrared receiving probe body 511, the first infrared receiving probe matrix 512, and the third infrared receiving probe matrix 513 receive signals from the infrared emission probe 503. The signal converter 506 converts the received infrared signals into different intensity currents, corresponding to different colors of the control indicator light 507, achieving graded indication of the tower crane inclination angle. When the signal is abnormal, the signal converter 506 can also trigger the alarm 504 to work.

[0032] The inclination monitoring mechanism 5 monitors the inclination of the tower crane tower body in real time by emitting and receiving infrared signals. It uses graded infrared receiving components to accurately perceive different inclination angles, and cooperates with the signal conversion and alarm system to timely alert the staff and remind them to take appropriate measures, effectively ensuring that the tower crane works within a safe inclination range and avoiding safety accidents caused by excessive inclination.

[0033] The working principle of the above embodiment is:

[0034] First, the infrared emission assembly 51 starts working. The power supply mounting plate 501 is fixed at the top of the tower body 2 frame to provide support for the power supply module 502. The power supply module 502 supplies power to the infrared emission probe 503, enabling it to continuously emit infrared signals. This signal serves as the starting signal source of the entire monitoring system, providing a basis for subsequent monitoring work.

[0035] Secondly, the receiving components in the infrared receiving and alarm assembly 52 start to work, the first infrared receiving probe body 511, the first infrared receiving probe matrix 512 and the third infrared receiving probe matrix 513 located at the bottom of the frame of the tower body 2 are responsible for receiving the infrared signals emitted by the top infrared emitting probe 503.

[0036] Then, the signal converter 506 starts to work. When the above-mentioned receiving components receive the infrared signals, the signal converter 506 converts the infrared signals into different intensity currents, which correspond to different inclination angle information.

[0037] Next, the indicator light 507 works according to the converted current. Different intensity currents control different color lights of the indicator light 507 to turn on, so as to realize the grading indication of the inclination angle of the tower crane. The green light turning on may indicate that the tower crane is in the normal inclination angle range, the yellow light turning on indicates that the inclination angle is increased, and the red light turning on means that the inclination angle is large and has approached the dangerous range.

[0038] Finally, the alarm part starts to work. When the signal converter 506 detects that the signal is abnormal, that is, the inclination angle of the tower crane reflected by the infrared signal exceeds the safety range, the alarm 504 electrically connected with the power module 502 and installed on one side of the car 4 works to timely alarm the staff and remind them to take corresponding measures to ensure the safe operation of the tower crane.

[0039] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
