[0002] Cranes are commonly used mechanical equipment in various engineering constructions. Under the load of the construction process, each working part has a certain amount of deformation. The large structural parts of the crane may undergo large deformation due to its own structural characteristics, such as crawler cranes. During the hoisting operation, when the truss jib is subjected to other external forces, it is very easy to have a large lateral deflection and exceed the set safety threshold, which leads to certain safety hazards when the crane is operating, especially when the jib If the arm length of the boom is too long, for example, when the arm length of the boom reaches more than 100 meters, the above safety hazards are more likely to occur

Embodiment Construction
[0045] In order to effectively improve the safety and reliability of crane operations, the embodiments of the present invention provide a crane jib attitude monitoring and control system, method, device and crane. In this technical solution, the control device can judge whether the attitude of the boom is deflected according to the real-time position of the hook detected by the distance detection device. Skew alarm to alarm device sends out a skew alarm, prompting the operator of the crane to take corresponding safety measures after receiving the skew alarm, thereby improving the safety and reliability of the crane operation. The present invention will be described in detail below with specific embodiments and in conjunction with the accompanying drawings.
[0046] refer to figure 1 and figure 2 As shown, the deflection of the boom refers to the tilt of the boom in the longitudinal vertical plane, such as figure 1 and figure 2 In the coordinate system shown in , the plane ...

The invention relates to the technical field of engineering machinery, and discloses a control system, a control method and a control device for monitoring a cantilever crane posture of a crane, and the crane. The control system, the control method and the control device are used for effectively improving the operating safety and reliability of the crane. The system comprises two distance detection devices and a control device, wherein the two distance detection devices are arranged on a first mounting point and a second mounting point on a fixing section of the crane, and are respectively used for detecting a first distance between a lifting hook and the first mounting point, and a second distance between the lifting hook and the second mounting point; the first mounting point and the second mounting point are respectively distributed on symmetrically transverse vertical surfaces on two sides of the lifting hook; and the control device is connected with the distance detection devices via signals, and are used for judging whether the cantilever crane deviates or not and determining the deviation coefficient of the cantilever crane according to the first distance and the second distance, and outputting a deviation alarm signal when the deviation coefficient of the cantilever crane is not smaller than the set safety threshold.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a boom attitude monitoring and control system, method, device and crane of a crane. Background technique [0002] Cranes are commonly used mechanical equipment in various engineering constructions. Under the load of the construction process, each working part has a certain amount of deformation. The large structural parts of the crane may undergo large deformation due to its own structural characteristics, such as crawler cranes.
