[0024] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figure 1 As shown, the embodiment of the present invention includes:

[0026] A tower crane safety monitoring and early warning system, the system consists of an operator identity authentication device 8, a beam anti-detachment detection device 2, a sleeve horizontal detection device 3, a jacking cylinder extension detection device 4, a jacking beam support hinge axis in place detection device 5, an anemometer device 6, a monitoring and warning device 7, a central control box 1 and a mobile client 9.

[0027] Preferably, the operator identity verification device 8 of the tower crane safety monitoring and early warning system is installed on the central control box 1. Before each installation or jacking operation of the tower crane, the operating workers, safety officers and other staff members need to log in by face recognition on the central control box 1. The operation can only be started after the background confirms that the personnel and the number of people are correct. Otherwise, the central control box 1 will not start the power supply of the tower crane.

[0028] Preferred as Figure 2 The beam anti-detachment detection device 2 of the tower crane safety monitoring and early warning system is fixed on the jacking beam through a bracket, and the photoelectric switch detection part is aligned with the beam anti-detachment device. When the anti-detachment device is not installed in place, the photoelectric switch will issue a warning through the alarm and cut off the power supply of the jacking cylinder to prevent the jacking operation from being carried out. In addition, a warning signal will be sent to the central control box 1.

[0029] Preferred as Figure 2 and Figure 3 As shown, the frame level detection device 3 of the tower crane safety monitoring and early warning system is composed of a bracket and a photoelectric switch. The bracket is installed on the tower crane frame and connected to the tower crane frame by bolts; the photoelectric switches are symmetrically arranged on the bracket and evenly distributed on the four sides of the frame. The horizontal condition of the frame is judged by the different monitoring values ​​of the photoelectric switches. When the frame level value exceeds the preset range, an alarm is issued and the power supply for the jacking operation is stopped, and a warning signal is sent to the central control box 1.

[0030] Preferred as Figure 5As shown, the jacking cylinder extension detection device 4 of the tower crane safety monitoring and early warning system is composed of a jacking cylinder and a pull-wire sensor; the pull-wire sensor is arranged at both ends of the jacking cylinders on both sides, and measures the telescopic length of the jacking cylinder in real time during operation. When the jacking length reaches a preset value, it prompts that the jacking operation is completed. When the jacking length exceeds the preset value, the power supply of the jacking equipment is cut off, and a warning signal is sent to the central control box 1 at the same time.

[0031] Preferably, the jacking beam support hinge axis in place detection device 5 of the tower crane safety monitoring and early warning system is composed of a tower crane jacking beam support, a photoelectric switch, a jacking beam, and an indicator light. The photoelectric switch monitors whether the jacking beam hinge axis enters the jacking beam support and sends a signal to the indicator light; when the tower crane jacking beam hinge axis enters the jacking beam support, it displays green; when the tower crane jacking beam hinge axis detaches from the jacking beam support, it displays red and issues an alarm, and the jacking operation cannot be continued, and a warning signal is sent to the central control box 1 at the same time.

[0032] Preferably, the anemometer device 6 of the tower crane safety monitoring and early warning system is no different from the existing anemometer device 6, except that when it detects that the wind speed is too high, it will send a warning signal to the central control box 1 to stop the operation.

[0033] Preferably, the monitoring and warning device 7 of the tower crane safety monitoring and early warning system is composed of multiple cameras and speakers, which are installed in the tower crane operating room and the frame, and are connected to the central control box 1 through lines; when the monitor of the central control box 1 or the mobile client 9 sees that the operator has unsafe behavior through the camera, a reminder can be issued to the operator or driver through the speaker.

[0034] Preferably, in the central control box 1 of the tower crane safety monitoring and early warning system, the aforementioned seven devices are connected to the central control box 1 by wires, the lines and wires are laid on the tower crane together, and the central control box 1 is operated on the ground; there is a display screen on the box, which can display the picture taken by the camera in the monitoring and warning device 7 in real time, and will issue an alarm and display the cause of the alarm when receiving the alarm signal from other devices; in addition, the central control box 1 can remotely shut down the power supply of the jacking cylinder, and issue a warning to the operator through the speaker of the monitoring and warning device 7.

[0035] Preferably, the mobile client 9 of the tower crane safety monitoring and early warning system is connected to the central control box 1 via a wireless network, has all the functions of the central control box 1, and can be remotely operated.

[0036] Compared with the existing technology, this invention monitors the entire process of tower crane installation, disassembly and jacking operations in real time, can monitor and warn "unsafe human behavior", monitor and force the operation to stop several typical "unsafe conditions of objects", and effectively ensure safety during the operation.
