Problems solved by technology
[0003] In the prior art, there are two methods for monitoring the outrigger force. The first method is to calculate the outrigger force by monitoring the pressure in the outrigger cylinder. However, during the reciprocating movement of the piston in the outrigger cylinder, the There is friction on the inner wall of the outrigger cylinder. In addition, there is a problem of holding pressure inside the outrigger cylinder, which leads to large errors in the monitoring results of the outrigger force. The second method is to install a force sensor on the outrigger. The force sensor can Detect outrigger force, however, during the operation of the crane, it is impossible to ensure that the outrigger is always perpendicular to the ground, so that the outrigger force detected by the force sensor is not necessarily the force perpendicular to the ground. There is also a large error in the force monitoring results
Since the above two methods have large errors in the detection results of the outrigger force, there is a possibility of overturning accidents during the operation of the crane, which is not conducive to ensuring the safety of the crane

The invention provides a method for measuring the force of an outrigger of a crane, which belongs to the technical field of engineering machinery. Wherein, the crane includes working equipment and a plurality of outriggers for supporting the working equipment, and an angle sensor and a force sensor are respectively arranged on each outrigger, and the force measurement method of the outrigger of the crane includes: respectively obtaining The angle signal of the angle sensor of the leg and the pressure signal of the force sensor respectively calculate the vertical force of each leg according to the angle signal of the angle sensor of each leg combined with the pressure signal of the force sensor. The application can effectively improve the force detection accuracy of the legs of the crane, prevent the crane from overturning accidents, and improve the safety of the crane.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a method for measuring the force on the legs of a crane. Background technique [0002] In construction machinery, for example, concrete pump trucks, wheeled cranes, etc. usually use multiple outriggers to support the entire operating equipment when they are working. Take cranes as an example, due to improper support or overloading of cranes during operation, tipping accidents often occur. In order to prevent the crane from tipping over during operation, it is usually necessary to monitor the outrigger force of the outrigger. [0003] In the prior art, there are two methods for monitoring the outrigger force. The first method is to calculate the outrigger force by monitoring the pressure in the outrigger cylinder. However, during the reciprocating movement of the piston in the outrigger cylinder, the There is friction on the inner wall of the outrigger cylinder. In...
