A mechanical equipment angle detection device

Abstract

The invention discloses a mechanical equipment angle detection device. The device comprises a bending plate, an angle sensor, a connecting rod and a pull rod assembly; the angle sensor is fixedly mounted on the bending plate; one end of the connecting rod is connected with a mandrel of the angle sensor; the other end of the connecting rod is connected with the pull rod assembly; the connecting rodand the pull rod assembly are assembled at an obtuse angle; the pull rod assembly and the connecting rod can relatively rotate around a connecting point; and when the device is used for detecting anangle of rotation of second equipment around first equipment, the other end of the bending plate is connected with the first equipment, and the other end of the pull rod assembly is connected with thesecond equipment. The angle of the to-be-detected equipment is detected in a manner of combining the connecting rod with the pull rod assembly between the angle sensor and the to-be-detected equipment; the connecting rod and the pull rod assembly are assembled at the obtuse angle; the pull rod assembly and the connecting rod can freely rotate around the connecting point; and when the angle sensorhas an installation coaxiality error, the connecting rod and the pull rod assembly can be adjusted in distance by changing the angle, so that the angle sensor is prevented from being damaged by shearing force.

Description

technical field [0001] The invention belongs to the technical field of construction machinery equipment, and in particular relates to a mechanical equipment angle detection device. Background technique [0002] The operation reliability and safety of mechanical equipment are the key indicators of mechanical equipment design. In order to achieve reliability and safety, the electrical system of the vehicle needs to detect various parameters of the equipment, and then use the control logic to ensure the reliability and safety of operation. . Especially for boom-type equipment, such as cranes, fire trucks, etc., the relative rotation angle of the boom is a key parameter for the realization of vehicle control logic and the definition of safe working range, and the accuracy of its measurement will directly determine the reliability and reliability of the product. safety. Therefore, it is very important to design an effective mechanical equipment angle detection device. [0003]...

Problems solved by technology

[0007] The first type of angle detection device, because the connecting rod and the angle sensor are rigidly connected, if there is an error in the coaxiality between the angle sensor and the rotation center, the angle sensor will bear the lateral shear force of the connecting rod on it, which will cause damage to the sensor

[0008] The second type of angle detection device, although the meshing accuracy of nylon gears is not high, can also measure the angle more accurately, but this device requires sufficient space for the installation of nylon gears, especially for the relative rotation angle measurement of small booms, it is difficult Room for nylon gears
