Embodiment 1

[0055] An adjacent fixed crane jib 13 anti-collision system, the system includes: a data processing module 1 for data processing. A first rotation sensing device 2a connected to the data processing module 1 and used to obtain the rotation state of the first boom 13 . The second rotation sensing device 2b is connected with the data processing module 1 and is used to obtain the rotation state of the second boom 13 adjacent to the first boom 13 . It is connected with the data processing module 1 and is used to identify the first early warning module 3a whose rotation orientation of the first boom 13 is within the first early warning area J1. It is connected with the data processing module 1 and is used to identify the second early warning module 3b whose rotation orientation of the second boom 13 is within the second early warning area J2. Connect with described data processing module 1, be used for sending the warning device 4 of early warning signal; Be connected with describe...

Embodiment 2

[0057] Embodiment 1 is repeated, except that the system further includes: a first brake module 5a connected to the data processing module 1 for identifying that the rotation orientation of the first boom 13 is within the first interference region G1. It is connected with the data processing module 1 and is used to identify the second braking module 5b whose rotation orientation of the second boom 13 is within the second interference area G2. Connected with the data processing module 1, the first cutting module 6a is used to cut off the power of the first driving device that drives the first boom 13 to rotate. Connected with the data processing module 1, the second cutting module 6b is used to cut off the power of the second driving device that drives the second boom 13 to rotate.

Embodiment 3

[0059]Repeat embodiment 2, only the first early warning area J1, the second early warning area J2, the first interference area G1, and the second interference area G2 are specifically: the circle formed by the rotation of the first boom 13 and the circle formed by the rotation of the second boom 13 The resulting circles have overlapping regions that overlap and interfere with each other. The first interference area G1 is a sector corresponding to the overlapping area on the circle formed by the rotation of the first boom 13 , and the central angle of the first interference area G1 is α1. The second interference area G2 is a sector corresponding to the overlapping area on the circle formed by the rotation of the second boom 13 , and the central angle of the second interference area G2 is α2. The first early warning area J1 is a fan-shaped area on the circle formed by the rotation of the first boom 13, and the first interference area G1 is within the first early warning area J1,...

Abstract

Provided is a fixed crane boom anti-collision system and a crane. The system comprises a data processing module for data processing, a first rotation sensing device connected with the data processing module and used for acquiring the rotation state of a first boom, a second rotation sensing device connected to the data processing module and used for acquiring the rotation state of a second boom adjacent to the first boom, a first early warning module for identifying the first boom rotation orientation within a first early warning region, a second early warning module for identifying the second boom rotation orientation in a second early warning region, an early warning device used for issuing an early warning signal and an image acquisition device used for real-time acquisition of the image information of the relative positions of the first boom and the second boom. Compared with the prior art, the fixed crane boom anti-collision system can promptly remind the staff to pay attention to the operating state of the booms of the adjacent crane, improve the work efficiency, increase the working area of the booms and reduce the occurrence rate of production accidents.

Description

technical field [0001] The invention relates to a fixed crane arm frame anti-collision system, which belongs to the technical field of engineering machinery. The invention also relates to a stationary crane. Background technique [0002] With the development of the world economy, the demand for cranes is getting higher and higher. In order to achieve the purpose of efficient and fast loading and unloading of goods, the distance between the cranes is set to be similar. In many cases, two or more cranes are required to move simultaneously. [0003] Among the many cranes, the fixed crane is a crane that rotates around a fixed axis, and its working area is limited. Therefore, in many cases, the fixed cranes are used in pairs or in combination, that is, the rotation ranges of the jibs of adjacent fixed cranes have overlapping areas, resulting in collisions between adjacent cranes. [0004] In the prior art, for the above problems, the general solution is: basically use laser ...
