Embodiment Construction
[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0025] figure 1 It is a structural schematic diagram of the detection device for the deviation of the superlift counterweight of the crane according to the present invention. As shown in the figure, the detection device includes four components, specifically an angle sensor 1 , a length sensor 3 , an inclination sensor 4 and a controller 2 . Wherein, the angle sensor 1 , the length sensor 3 and the inclination sensor 4 are all coupled with the controller 2 . In this detection device, the angle sensor 1 is used to collect the left and right offsets of the superlift counterweight; the inclination sensor 4 is used to collect the front, rear, left and right offset angles of the superlift counterweight; and the length sensor 3 is It is used to collect the front and rear deviation displacement of superlift counterweight. The above three sensors transmit the coll...

The invention provides a device for detecting the deviation of a superlift counterweight of a crane. The device comprises an angle sensor, a length sensor, an tilt angle sensor and a controller, wherein the angle sensor is used for acquiring a leftward deviation angle and a rightward deviation angle of the superlift counterweight; the length sensor is used for acquiring a forward deviation displacement and a backward deviation displacement of the superlift counterweight; the tilt angle sensor is used for acquiring a forward deviation angle, a backward deviation angle, the leftward deviation angle and the rightward deviation angle of the superlift counterweight; the controller is used for performing comparison processing on the detected results of the sensors; and the angle sensor, the length sensor and the tilt angle sensor are connected to the controller. The device and a method for detecting the deviation of the superlift counterweight of the crane can efficiently detect the deviation of the superlift counterweight on the ground so as to timely adjust the superlift counterweight to ensure the safe operation of the crane. The detection device has the advantages of simple structure, convenient operation, timely adjustment and wide application to various cranes.
Description
technical field [0001] The invention relates to a crane detection device and method, in particular to a crane detection device and method for overlift counterweight deviation. Background technique [0002] As we all know, the normal operation of the crane is inseparable from the matching counterweight. When the crane is lifting, it needs to load and unload a certain weight of counterweight to keep it stable. The heavier the item being lifted by the crane, the greater the tonnage of the counterweight required. [0003] At present, during the lifting process, the superlifting counterweight of a large crane needs to slew or walk off the ground. However, with the hoisting of large equipment and complete sets of equipment, the tonnage of crawler cranes will become very large. In order to meet the needs of corresponding large-tonnage crawler cranes, the weight of the matching superlift counterweight has been increased accordingly. At this time, due to the large tonnage of ...
