Embodiment Construction

[0029] The technical scheme of the present invention will be described in detail below in conjunction with the accompanying drawings, taking a truck crane as an example.

[0030] like figure 2 As shown, the truck crane includes: a measuring box 100 , a signal processing receiver 200 , a car body 300 , a slewing mechanism 400 , a lifting rope 500 , a load 600 , a boom 700 , a pitching mechanism 800 and a hook 900 . The boom 700 of the truck crane can be telescopic, and under the action of the pitching mechanism 800, it can move in pitch. The measurement box 100 is fixed on the hook 900, and the signal processing receiver 200 is installed in the control box of the crane.

[0031] The detection idea of ​​the swing angle of the load space of the crane in the present invention can be combined with figure 1 illustrate. The measuring box 100 is installed on the hook / load at the end of the sling 500, and its function is to use the MEMS technology-based three-degree-of-freedom magn...

Abstract

The present invention discloses a crane load space swing angle detection technology and an apparatus thereof, wherein the apparatus comprises a measurement box and a signal receiving processor. According to the technology, a sensor in the measurement box arranged on a lifting hook/load measures a spatial attitude of the lifting hook/load relative to a geodetic coordinate, the signal receiving processor arranged on a crane body/boom measures a spatial attitude of the crane body/boom relative to the geodetic coordinate based on the sensor, a spatial attitude parameter of the crane load relative to the crane body/boom can be calculated through coordinate transformation, and the calculated parameter can be transmitted to a crane control box through a bus control unit to automatically control. With the present invention, a spatial swing condition of the crane load can be accurately measured so as to help the crane to achieve anti-swing control and improve safety production efficiency.

Description

technical field [0001] The invention belongs to the fields of instrumentation and automatic control, and in particular relates to a space posture measurement technology and device for a crane load. Background technique [0002] As a means of delivery, cranes are widely used in construction sites, bulk cargo terminals and warehouse scheduling operations. It uses cables attached to movable frames to lift and move heavy objects. Using flexible bodies such as ropes instead of rigid bodies makes the crane mechanism light and efficient. However, the use of flexible lifting also brings some negative effects. Due to the acceleration and deceleration of the carrier, the lifting action of the load, and the disturbance caused by wind and friction, the load will swing back and forth. Automatic anti-swing control should be carried out on the hook. First of all, it is necessary to know the swing information of the load in space, which becomes an important factor restricting the possibil...
