[0053] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0054] The intelligent tower crane introduction system of the present invention is described below with reference to the accompanying drawings.

[0055] like Figure 1 As shown, the present invention provides an intelligent tower crane loading system, wherein the intelligent tower crane loading system includes:

[0056] Introduce crossbeam 1;

[0057] The trolley 2 is movably mounted on the guide beam 1;

[0058] Lifting device 3 is used to connect to standard section 8 and to carry out lifting operations via tower crane hook 7;

[0059] The centering detection device 4 is installed on the introduction beam 1 and is used to control the tower crane hook 7 to drive the lifting device 3 to perform centering operation with the introduction beam 1, so that after the centering operation is completed, the tower crane hook 7 drives the lifting device 3 to move horizontally onto the introduction trolley 2.

[0060] When the intelligent introduction system of the tower crane is used, the hoisting device 3 is connected with the standard section 8 and hoisted to the tower crane hook 7, and the hoisting device 3 and the standard section 8 can be hoisted to the introduction end of the introduction beam 1 by controlling the tower crane hook 7, the centering detection device 4 arranged on the introduction beam 1 can be used to control the tower crane hook 7 to drive the hoisting device 3 to perform the centering operation with the introduction beam 1, and the position of the tower crane hook 7 can be adjusted through the centering detection device 4, so that the hoisting device 3 is kept aligned with the introduction beam 1 before entering the introduction beam 1, and after the centering operation is completed, the hoisting device 3 is directly driven by the tower crane hook 7 to move horizontally, so that the hoisting device 3 can be moved to the introduction trolley 2, and the introduction operation of the standard section 8 is completed, and the whole operation process does not need the operator to perform high-altitude operation on the operation platform, so that the operation difficulty is reduced, the installation efficiency is improved, and the safety is ensured. It should be particularly pointed out that the introduction end of the introduction beam 1 refers to the end where the standard section 8 starts to enter the introduction beam 1.

[0061] Specifically, the intelligent introduction system of the tower crane further comprises a safety monitoring device, which can be used to monitor the centering detection device 4, so as to control the tower crane hook 7 to move according to the feedback of the centering detection device 4, and the safety monitoring device can be arranged in the cab of the tower crane.

[0062] Referring to Figure 1 , Figure 2 and Figure 4 , in the embodiment of the application, the intelligent introduction system of the tower crane further comprises a first position detection device 5 arranged on the introduction trolley 2 and used to send a position detection signal when the hoisting device 3 moves to the introduction trolley 2, and after receiving the position detection signal sent by the first position detection device 5, the tower crane hook 7 can be controlled to move downward, so that the tower crane hook 7 is separated from the hoisting device 3, thereby avoiding the phenomenon that the introduction operation is not in place. Specifically, the first position detection device 5 can be in communication connection with the safety monitoring device, so as to facilitate the operator in the cab to make corresponding control quickly.

[0063] In the embodiment of the application, the first position detection device 5 comprises a distance sensor arranged on the introduction trolley 2 and used to send a position detection signal when the distance between the introduction trolley 2 and the hoisting device 3 reaches a preset distance, and when the hoisting device 3 has not reached the position opposite to the distance sensor, the distance sensor cannot detect the distance value, at this time, the control of the tower crane hook 7 driving the hoisting device 3 to move horizontally is continued, when the hoisting device 3 reaches the position opposite to the distance sensor, the distance sensor can detect the distance value between the introduction trolley 2 and the hoisting device 3, and when the detected distance value reaches the preset distance, the distance sensor can send a position detection signal to the safety monitoring device.

[0064] Referring to Figure 1 , Figure 3 and Figure 4 , in the embodiment, the surface of the lifting device 3 facing the surface where the distance sensor is arranged is provided with a boss part 325, and the distance sensor is configured to send a position detection signal when the boss part 325 is detected. As shown in Figure 9 and Figure 10 , when the surface where the distance sensor is arranged starts to be arranged opposite to the distance sensor, the distance sensor can start to detect a first distance value, which is the distance between the trolley 2 and the surface. The first distance value is compared with a preset distance. In the embodiment, the first distance value is not the preset distance, and then the control tower crane hook 7 continues to drive the lifting device 3 to move horizontally. However, the moving speed of the tower crane hook 7 can be reduced at this time, as shown in Figure 11 and Figure 12 , only when the lifting device 3 moves to the position where the boss part 325 is arranged opposite to the distance sensor, the distance sensor can detect a second distance value between the trolley 2 and the boss part 325. The second distance value is compared with the preset distance. The second distance value is the preset distance, and then the distance sensor can send a position detection signal to the safety monitoring device. In addition, since the boss part 325 protrudes from the surface of the lifting device 3 facing the surface where the distance sensor is arranged, the second distance value is obviously smaller than the first distance value, and there is a significant mutation in the distance detection of the distance sensor, so that the trolley 2 can be accurately positioned by the distance sensor and the boss part 325, so as to accurately hoist the lifting device 3 to the trolley 2.

At the same time, the centering detection device 4 is used to control the tower crane hook 7 to drive the lead-in hook 31 to perform the centering operation with the lead-in beam 1, so that the tower crane hook 7 drives the support rod 324 of the lead-in lifting appliance 32 to move into the guide opening 23 after the centering operation is completed, and the lead-in hook 31 is located at the upper end of the lead-in lifting appliance 32, the lead-in hook 31 is selected to perform the centering operation with the lead-in beam 1, so as to facilitate the layout design of the centering detection device 4.

That is, the first laser 41 can be emitted towards the guide end of the guide beam 1 first, and the tower crane hook 7 is adjusted so that the light spot of the first laser 41 falls into the first positioning area 314 of the second hoisting vertical plate 313, thereby determining the guide height of the guide hook 31, and then the second laser 42 is emitted, and the tower crane hook 7 is controlled to move horizontally at the guide height so that the light spot of the second laser 42 falls into the second positioning area 315 of the connecting plate 311, thereby determining the centering position of the guide hook 31.
