[0028] Combine the following Figure 1 A tower crane safety monitoring system and a tower crane provided in an embodiment of the utility model are described. It should be understood that the following description is only an illustrative implementation of the utility model and does not constitute any particular limitation to the utility model.

[0029] The first embodiment of the utility model provides a tower crane safety monitoring system, such as Figure 1 As shown, the tower crane safety monitoring system includes: a safe area projection device 100, which is installed on the boom of the tower crane and is used to project the safe working area of ​​the tower crane; a boom driving device 200, which is connected to the boom of the tower crane and is used to drive the boom to move to hoist and transfer heavy objects; a monitoring device 300, which is installed on the boom of the tower crane and is used to monitor obstacles in the safe working area of ​​the tower crane; a control device 400, which is connected to the monitoring device 300 and the boom driving device 200 and is used to adjust the working state of the boom driving device 200 based on the monitoring results of the monitoring device 300.

[0030] The tower crane safety monitoring system provided by the utility model includes a safety area projection device 100, a monitoring device 300, a boom drive device 200 and a control device 400. The safety area projection device 100 is installed on the boom of the tower crane, and it can project the safe working area of ​​the tower crane. For example, the safety projection device can project the safe working area of ​​the tower crane on the ground. The monitoring device 300 is installed on the boom of the tower crane, and it can monitor whether there are obstacles in the safe working area of ​​the tower crane. The boom drive device 200 can drive the boom to move to lift and transfer heavy objects. Among them, the boom drive device 200 includes a boom amplitude change drive mechanism and a hook lifting drive mechanism. The control device 400 can control the working state of the boom drive device 200 based on the monitoring results of the monitoring device 300 to ensure that the tower crane can lift heavy objects in a safe state.

[0031] Through this structural setting, when the tower crane is hoisting heavy objects, the control device 400 can control the working state of the boom driving device 200 based on whether there are obstacles in the safe working area of ​​the tower crane monitored by the monitoring device 300, thereby ensuring the safety of the tower crane hoisting heavy objects. At the same time, the safe area projection device 100 can form a certain warning effect for people on the ground, and can also further improve the safety of the tower crane hoisting heavy objects.

[0032] For example, the monitoring device 300 can be a 360° panoramic camera, which can not only monitor the safe working area of ​​the tower crane, but also comprehensively monitor the surrounding environment of the tower crane. The safe area projection device 100 includes a projection lamp, which can project the safe working area of ​​the tower crane, which also has a certain warning effect on the surrounding personnel.

[0033] For example, in actual working process, when there is an obstacle in the safe working area of ​​the tower crane, the control device 400 can control the boom driving device 200 to stop the boom of the tower crane from moving; or, when there is an obstacle in the safe working area of ​​the tower crane, the control device 400 controls the boom driving device 200 to move the boom of the tower crane in the direction away from the obstacle.

[0034] In one embodiment of the present utility model, the tower crane safety monitoring system further includes a display device 500 and a manual emergency control device 600 .

[0035] The display device 500 and the manual emergency control device 600 are both arranged in the driver's cab of the tower crane. The display device 500 is connected to the monitoring device 300. The manual emergency control device 600 is connected to the boom driving device 200.

[0036] For example, a display device 500 and a manual emergency control device 600 are arranged in the driver's cab. The display device 500 is connected to the monitoring device 300 so as to display the images captured by the monitoring device 300 in the driver's cab for the operating driver to view in real time. The manual emergency control device 600 is provided for the operating driver to perform manual emergency operations. When the operating driver observes dangerous factors based on the display device 500 or with the naked eye, the manual emergency control device 600 can be used to urgently control the boom drive device 200 to prevent the occurrence of dangerous accidents. In this way, dual insurance of automatic monitoring and control and manual monitoring and control can be achieved, further improving the reliability of the tower crane safety monitoring system.

[0037] In one embodiment of the present invention, the tower crane safety monitoring system further includes a level detection device 700 .

[0038] The horizontal detection device 700 is installed on the boom of the tower crane and is used to detect the tilt angle of the hoisted weight. The control device 400 is connected to the horizontal detection device 700 and is used to control the working state of the boom driving device 200 based on the detection result of the horizontal detection device 700.

[0039] For example, Figure 1 As shown, a horizontal detection device 700 is provided on the boom of the tower crane. The horizontal detection device 700 can detect the inclination angle of the heavy object hoisted by the hook. When the hoisted heavy object is in a horizontal state, the hoisting stability and safety are high, and dangerous accidents such as heavy objects falling are not likely to occur. When the hoisted heavy object is in an inclined state, the hoisting stability and safety are poor, and dangerous accidents such as heavy objects falling are likely to occur. For example, a preset safe inclination angle can be set in the control device 400. During the actual hoisting process, when the actual inclination angle of the hoisted heavy object exceeds the preset safe inclination angle, the control device 400 controls the boom drive device 200 to stop the boom of the tower crane from moving to avoid the occurrence of dangerous accidents.

[0040] In one embodiment of the present utility model, the tower crane safety monitoring system further includes a first warning device 800. The first warning device 800 is connected to the control device 400. The control device 400 is used to control the working state of the first warning device 800 based on the detection result of the monitoring device 300.

[0041] In another embodiment of the utility model, the tower crane safety monitoring system further includes a second warning device 900. The second warning device 900 is arranged in the driver's cab of the tower crane. The second warning device 900 is connected to the control device 400. The control device 400 is used to control the working state of the second warning device 900 based on the detection result of the horizontal detection device 700.

[0042] In one embodiment of the utility model, when there is an obstacle in the safe working area of ​​the tower crane, the control device 400 controls the activation of the first warning device 800; when the actual inclination angle of the hoisted heavy object exceeds the preset safe inclination angle, the control device 400 controls the activation of the second warning device 900.

[0043] For example, the first warning device 800 can be arranged in the driver's room and a position close to the ground. The first warning device 800 may include a warning bell and / or a warning light. When the monitoring device 300 detects that there is an obstacle in the safe working area of ​​the tower crane, the control device 400 controls the first warning device 800 to sound an alarm to prompt the operating driver and the ground personnel. As a result, the operating driver can be more vigilant and perform corresponding emergency operations when necessary. For example, the corresponding emergency operations can be performed through the manual emergency control device 600, and the ground personnel can promptly discover the danger and avoid it to a safe area. The second warning device 900 can be arranged in the driver's room and / or a position close to the ground. The second warning device 900 can also include a warning bell and / or a warning light. When the horizontal detection device 700 detects that the hoisted heavy object is tilted, the control device 400 controls the second warning device 900 to sound an alarm to prompt the operating driver, so that the operating driver performs an emergency stop hoisting operation through the manual emergency control device 600. In addition, the second warning device 900 can also warn the surrounding personnel to avoid.

[0044] An embodiment of the second aspect of the utility model provides a tower crane, comprising the tower crane safety monitoring system as described above.

[0045] Furthermore, in the tower crane provided by the present invention, since it includes the tower crane safety monitoring system as described above, it also has the advantages as described above.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
