Description

Technical Field

[0001] This utility model relates to the field of tower crane technology, and in particular to a safety monitoring device for construction tower cranes. Background Technology

[0002] Tower cranes, also known as tower hoists, are indispensable large-scale lifting equipment in construction, resembling tall towers in appearance. Standing on the construction site, their lifting arms act like giant arms, vertically lifting heavy building materials such as steel bars, concrete, and formwork. Through rotation and luffing operations, they are precisely transported to designated locations, making them invaluable assistants in the construction of high-rise buildings and bridges.

[0003] Existing tower crane hook monitoring equipment is fixed to the tower crane to monitor the hook. When the hook is raised to the top of the boom or lowered to near the ground, the fixed-view monitoring equipment may cause the hook and the load to fall out of the monitoring range due to obstruction by the tower body, boom or limited view. This makes it impossible to identify abnormalities such as loose slings or tilted loads, increasing the risk to personnel. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a safety monitoring device for tower cranes used in construction.

[0005] This utility model is achieved by the following technical solution: a safety monitoring device for a construction tower crane, including a tower crane, a wind speed sensor fixedly connected to the top of the tower crane, a sensor data acquisition box fixedly connected to the outer wall of the tower crane, a monitoring component provided on the outer wall of the tower crane, and a lighting component provided on the top of the tower crane;

[0006] The monitoring component includes a housing, which is fixedly connected to the outer wall of the tower crane. A support block is fixedly connected to the bottom of the inner wall of the housing, and a motor is fixedly connected to the top of the support block. A worm gear is fixedly connected to the output end of the motor, and a worm wheel is meshed with the worm gear. A rotating rod is fixedly connected to the inner wall of the worm wheel, and a support plate is rotatably connected to the outer wall of the rotating rod. A connecting plate is fixedly connected to the outer wall of the rotating rod, and a hook monitoring camera is fixedly connected to the end of the connecting plate away from the support plate.

[0007] As a further improvement to the above solution, the worm gear is rotatably connected inside the housing, and the support plate is fixedly connected to the bottom of the inner wall of the housing.

[0008] Through the above technical solution, a wind speed sensor at the top of the tower crane senses the ambient wind speed in real time and transmits the data to a sensor data acquisition box fixed on the outer wall of the tower crane for subsequent analysis and early warning. At the same time, the data is synchronized to the backend, where artificial intelligence analyzes and processes the data to improve on-site operational safety. A support block is fixed on the inner wall of the outer shell, supporting the motor. When the motor starts, it drives the worm gear to rotate. The worm gear meshes with the worm wheel, converting the rotational motion of the worm gear into the circular motion of the worm wheel. The worm wheel drives the rotating rod to rotate within the support plate, thereby causing the connecting plate and the hook monitoring camera to rotate around the rotating rod as the center. This enables multi-angle and wide-range dynamic monitoring of the hook, compensating for the shortcomings of a fixed viewing angle, facilitating operators to promptly detect hook abnormalities, and reducing the probability of on-site safety accidents.

[0009] As a further improvement to the above solution, the lighting component includes a housing, which is fixedly connected to the top of the tower crane. A sliding groove is provided inside the housing, and a slider is rotatably connected to the outer wall of the sliding groove. A rotating column is fixedly connected to the outer wall of the slider.

[0010] As a further improvement to the above solution, a motor is fixedly connected to the bottom of the rotating column, the motor is fixedly connected to the bottom of the inner wall of the outer casing, a T-shaped groove is opened at the top of the rotating column, a motor is fixedly connected to the inside of the rotating column, and a threaded rod is fixedly connected to the output end of the motor.

[0011] As a further improvement to the above solution, the threaded rod is rotatably connected inside the rotating column, the threaded rod is threadedly connected to a T-shaped slider, the T-shaped slider is slidably connected to the outer wall of the T-shaped groove, and a fixing plate is fixedly connected to the top of the T-shaped slider.

[0012] As a further improvement to the above solution, a fixing rod is fixedly connected inside the fixing plate, a connecting block is rotatably connected to the outer wall of the fixing rod, and a fixing rod is rotatably connected to the end of the connecting block away from the fixing rod.

[0013] As a further improvement to the above solution, a fixing block is fixedly connected to the outer wall of the fixing rod one, a lighting lamp is fixedly connected to the bottom of the fixing block, a fixing rod two is rotatably connected inside the fixing block, a support frame is fixedly connected to the outer wall of the fixing rod two, and the support frame is fixedly connected to the top of the rotating column.

[0014] Through the above technical solution, motor two drives the threaded rod to rotate, and the threaded rod and T-shaped slider are threadedly driven, causing the T-shaped slider to slide in the T-shaped groove. A fixing plate is fixed on the top of the T-shaped slider, and the fixing plate is fixed to the fixing rod. Fixing rod one is fixed to the fixing block. The connecting block rotates with the fixing rod and fixing rod one, thereby causing the fixing block to drive the lighting lamp to adjust a certain angle around fixing rod two as the center. This makes it convenient for personnel to observe the tower crane, ensuring that the hook operation is clearly visible at night or in low visibility environments, and improving the safety of the work site.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention uses a wind speed sensor at the top of the tower crane to sense the ambient wind speed in real time and transmits the data to a sensor data acquisition box fixed to the outer wall of the tower crane for subsequent analysis and early warning. Simultaneously, the data is synchronized to a backend system where artificial intelligence analyzes and processes the data to improve on-site operational safety. A support block is fixed to the inner wall of the outer shell, supporting the motor. When the motor starts, it drives the worm gear to rotate, and the worm gear meshes with the worm wheel, converting the worm's rotational motion into the worm wheel's circular motion. The worm wheel drives the rotating rod to rotate within the support plate, causing the connecting plate and the hook monitoring camera to rotate around the rotating rod. This enables multi-angle, wide-range dynamic monitoring of the hook, compensating for the limitations of a fixed viewing angle, facilitating timely detection of hook abnormalities by operators, and reducing the probability of on-site safety accidents.

[0017] This invention uses a second motor to drive a threaded rod to rotate. The threaded rod and the T-shaped slider are connected by a threaded transmission, allowing the T-shaped slider to slide within a T-shaped groove. A fixing plate is fixed to the top of the T-shaped slider. Simultaneously, the fixing plate is fixed to the fixing rod, and the fixing rod is fixed to the fixing block. The connecting block rotates with the fixing rod and the fixing rod, causing the fixing block to drive the lighting lamp to adjust its angle around the fixing rod. This allows personnel to easily observe the tower crane, ensuring that the hook operation is clearly visible at night or in low visibility conditions, thus improving the safety of the work site.

Meanwhile, the outer casing 501 protects the motor 505, ensuring the normal operation of the outer casing 501 and preventing interference.
