It should be understood that the specific embodiments described herein are for purposes of illustration and explanation only and are not intended to limit the present invention.
The intelligent introduction system of the tower crane of the present invention is described below with reference to the accompanying drawings.
As shown in fig. 1, the present invention provides an intelligent introduction system for a tower crane, wherein the intelligent introduction system for a tower crane comprises:
Introducing a cross beam 1;
a introducing trolley 2 movably arranged on the introducing beam 1;
the lifting device 3 is connected with the standard section 8 and is used for carrying out lifting operation through the tower crane lifting hook 7;
The centering detection device 4 is arranged on the introducing cross beam 1 and is used for controlling the tower crane lifting hook 7 to drive the lifting device 3 to perform centering operation with the introducing cross beam 1, so that the tower crane lifting hook 7 drives the lifting device 3 to horizontally move onto the introducing trolley 2 after the centering operation is completed.
When the intelligent introducing system of the tower crane is used, the lifting device 3 is connected with the standard section 8 and is lifted onto the tower crane lifting hook 7, the lifting device 3 and the standard section 8 can be lifted to the introducing end of the introducing cross beam 1 by controlling the tower crane lifting hook 7, the centering detection device 4 arranged on the introducing cross beam 1 can be used for controlling the tower crane lifting hook 7 to drive the lifting device 3 to perform centering operation with the introducing cross beam 1, the position of the tower crane lifting hook 7 can be adjusted by the centering detection device 4, so that the lifting device 3 is aligned with the introducing cross beam 1 before entering the introducing cross beam 1, after the centering operation is completed, the lifting device 3 can be ensured to move onto the introducing trolley 2 by directly driving the lifting device 3 to perform horizontal movement, the introducing operation of the standard section 8 is completed, and an operator does not need to stand on an operating platform for performing overhead operation in the whole operation process, thereby achieving the purposes of reducing operation difficulty, improving installation efficiency and ensuring safety. It should be noted that, the introduction end of the introduction cross member 1 means the end at which the standard knot 8 starts to enter the introduction cross member 1.
Specifically, the intelligent introduction system of the tower crane further comprises a safety monitoring device, wherein the safety monitoring device can be used for monitoring the centering detection device 4 so as to control the tower crane lifting hook 7 to move according to feedback of the centering detection device 4, and the safety monitoring device can be arranged in a cab of the tower crane.
Referring to fig. 1,2 and 4, in the embodiment of the present invention, the intelligent introducing system of the tower crane further includes a first in-place detecting device 5, where the first in-place detecting device 5 is disposed on the introducing trolley 2 and is used to send out an in-place detecting signal when the lifting device 3 moves onto the introducing trolley 2, after receiving the in-place detecting signal sent out by the first in-place detecting device 5, the tower crane lifting hook 7 can be controlled to move downward, so that the tower crane lifting hook 7 is separated from the lifting device 3, and thus a phenomenon that the introducing operation is not in place can be avoided. In particular, the first in-place detection device 5 may be communicatively connected to a safety monitoring device, so as to facilitate the rapid corresponding control by the operator in the cab.
In the embodiment of the invention, the first in-place detection device 5 comprises a distance sensor, the distance sensor is arranged on the introducing trolley 2 and is used for sending out an in-place detection signal when detecting that the distance between the introducing trolley 2 and the lifting device 3 reaches a preset distance, when the lifting device 3 does not reach the position opposite to the distance sensor, the distance sensor can not detect a distance value, at the moment, the lifting device 3 is driven to horizontally move by continuously maintaining the control tower crane lifting hook 7, when the lifting device 3 reaches the position opposite to the distance sensor, the distance sensor can detect the distance value between the introducing trolley 2 and the lifting device 3, and when the detected distance value reaches the preset distance, the distance sensor can send out an in-place detection signal to the safety monitoring device.

And because the boss portion 325 protrudes out of the surface of the lifting device 3 facing the distance sensor, the second distance value is obviously smaller than the first distance value, and an obvious mutation exists in the distance detection of the distance sensor, so that the introduction trolley 2 can be accurately positioned through the distance sensor and the boss portion 325, and the lifting device 3 can be accurately lifted onto the introduction trolley 2.
