[0002] In the field of modern construction, tower cranes, as a key hoisting equipment, are widely used in various construction projects. With the continuous expansion of building scale and the continuous increase of construction height, the use frequency and working intensity of tower cranes are also increasing. However, tower cranes face many safety risks during operation, such as tower body tilting, component loosening or displacement, etc. Once these problems cause accidents, not only will it cause serious property loss, but also may cause personnel casualties.

[0026] The monitoring and early warning mechanism 4 further comprises a third assembly pipe 411, a second assembly pipe adapter ring 412, an upper sealing plate 413, an infrared emitting assembly 414 and an infrared emitter positioning plate 415. The third assembly pipe 411 is movably sleeved at the top of the supporting inner ring 408, the second assembly pipe adapter ring 412 is movably sleeved at the top of the third assembly pipe 411, the upper sealing plate 413 is fixedly installed at the top of the second assembly pipe adapter ring 412, the infrared emitting assembly 414 is fixedly installed at the top of the upper sealing plate 413 and the infrared emitter positioning plate 415 is fixedly connected to one side of the upper sealing plate 413 and fixedly installed at one side of the tower body 2.

[0027] The vacuum pump 406 is fixedly installed at the top of the bottom plate 1 and the infrared receiving assembly 403 is arranged directly below the infrared emitting assembly 414.

[0028] The inner part of the support inner ring 408 and the positioning ring 409 is provided with a sealed cavity, and the inner part of the cavity is fixedly connected with an arched support plate.

[0029] The top and bottom of the first assembly pipe connecting ring 404 are provided with limiting grooves, and the bottom of the limiting grooves is provided with a sealing ring. The diameter of the second assembly pipe 407 is equal to the diameter of the limiting groove of the first assembly pipe connecting ring 404.

[0030] The lower sealing plate 401, the first assembly pipe 402, the first assembly pipe connecting ring 404, the second assembly pipe 407, the third assembly pipe 411, the second assembly pipe connecting ring 412 and the infrared emission assembly 414 jointly constitute a cylindrical sealed cavity, and the sealed cavity is communicated with the vacuum pump 406 through the adapter pipe 405.

[0031] The bottom of the infrared emission assembly 414 is provided with an infrared emission probe, and the position of the infrared emission probe corresponds to the position of the infrared receiving assembly 403.

[0032] It needs to be further explained that:

[0033] It utilizes the cooperation of the infrared emission assembly 414 and the infrared receiving assembly 403 to build an effective monitoring system. The infrared emission assembly 414 emits infrared rays downward from a high place, and the infrared receiving assembly 403 accurately receives below. Once the tower crane appears abnormal conditions such as tower body inclination and component displacement, the infrared transmission path will change, and the signal received by the receiving assembly will also change. Through the analysis of these signal changes, the abnormal state of the tower crane can be detected in time, so as to realize the real-time monitoring of the running state of the tower crane and provide key data support for safety warning.

[0034] The structure composed of the support inner ring 408, the positioning ring 409 and the support outer ring 410 is very important. The support inner ring 408 is sleeved on the related components to provide basic support. The positioning ring 409 is fixed on the outer ring of the support inner ring 408 to play a role in accurate positioning, ensuring that each component works cooperatively in the correct position. The support outer ring 410 further enhances the stability of the overall structure to resist possible impact and vibration from the outside. They jointly provide a stable structural guarantee for the monitoring and warning mechanism 4, so that it can normally function in the complex operating environment of the tower crane.

[0035] The cylindrical closed cavity formed by the lower sealing plate 401, the assembled pipes and the adapter rings is connected with the vacuum pump 406 through the adapter pipe 405, and the vacuum pump 406 can adjust the environment in the closed cavity, such as extracting air to form a specific air pressure environment, avoiding impurities such as dust and water vapor from the outside, reducing the interference of internal air flow on the transmission of infrared rays, providing a stable working environment for the infrared ray emitting assembly 414 and the infrared ray receiving assembly 403, and ensuring the accuracy and reliability of the monitoring and early warning system.

[0036] The working principle of the above embodiment is as follows:

[0037] Firstly, after the equipment is started, the infrared ray emitting assembly 414 starts to work and emits infrared rays downward from a high place, and the infrared ray receiving assembly 403 is located directly below and is ready to receive infrared ray signals at any time, so as to build an initial monitoring signal transmission link.

[0038] Secondly, during the normal operation of the tower crane, the infrared rays are stably transmitted from the emitting assembly to the receiving assembly, the receiving assembly continuously receives stable signals and converts them into electrical signals to transmit to the subsequent processing unit, indicating that the tower crane is in a normal state.

[0039] Then, once the tower crane has abnormal conditions such as tower body inclination and component displacement, the originally stable transmission path of the infrared rays will change, and this path change will change the signal strength, frequency and other characteristics received by the infrared ray receiving assembly 403.

[0040] Next, the receiving assembly transmits the changed signals to the signal analysis and processing module, which analyzes and calculates the signals to determine whether the signal change is beyond the normal range, so as to determine whether the tower crane has safety hazards.

[0041] Finally, the structure composed of the support inner ring 408, the positioning ring 409 and the support outer ring 410, and the cylindrical closed cavity formed by the lower sealing plate 401, the assembled pipes and the adapter rings, cooperate with the vacuum pump 406 to work, and ensure the stable operation of the entire monitoring and early warning mechanism 4, the stable structure avoids the influence of monitoring caused by external impact and vibration, the closed cavity and the vacuum pump 406 adjust the internal environment, reduce the interference of impurities and air flow, ensure the stability and reliability of the infrared monitoring link, and thus realize the safety monitoring and early warning function of the entire tower crane.

[0042] 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 structure, shape, principle of the present application should be covered within the protection scope of the present application.
