Device capable of monitoring rotation angle of swing mechanism in real time and monitoring method thereof

Abstract

The invention discloses a device capable of monitoring the rotation angle of a swing mechanism in real time and a monitoring method thereof, and belongs to the field of engineering machinery. The device comprises a concrete pump truck, a rotary supporting mechanism, a speed reducer, a rotating speed sensor and a monitoring terminal. The rotary supporting mechanism is installed on the concrete pumptruck, the speed reducer is installed on the rotary supporting mechanism, the rotating speed sensor is installed on the speed reducer, a first gear is arranged on the rotary supporting mechanism, a second gear is arranged on the speed reducer, the second gear is meshed with the first gear, and the rotating speed sensor is electrically connected with the monitoring terminal. The device is simple in structure. The rotating speed sensor is directly installed on the speed reducer, and the rotating speed sensor and the speed reducer are organically combined, so that the rotating speed sensor can output stable signals and is not easily interfered by the outside. Parameters of the speed reducer and output signals have a stable conversion relation, so that results obtained through real-time monitoring are accurate and can be visually observed through a computer, and data collection is quite convenient.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a device capable of real-time monitoring of the rotation angle of a slewing mechanism and a monitoring method thereof. Background technique [0002] In the concrete pump truck industry, there are generally three methods for measuring the rotation angle of the turntable (arm frame) or the rotation angle of the slewing mechanism. One is the form of proximity switch (the code disc rotates with the rotation of the gear, the code disc is processed into a sawtooth shape, and two proximity switches are used for induction); the other is a mechanical induction switch, with a small straight rod installed on the turntable, and the in-position switch is used Induction is carried out, and a signal is sent out when the rotation touches. One is that the shaft on the technical flange of the encoder is processed with a gap, and the encoder is used for induction above the shaft. Basically,...

Problems solved by technology

[0003] There are deficiencies in the above three methods: 1. The continuity of the encoder proximity switch is not enough, and the measured angle is intermittently beating. In addition, affected by the accuracy of the proximity switch, there are requirements for installation accuracy, and it is easy to fail to sense it.

2. The mechanical induction switch can only sense whether it is in place when it is rotated to a certain position. It can only control the maximum range of the rotation angle and cannot detect the rotation angle.

This form requires the shaft and the sensor to be coaxial, so it requires high installation and machining accuracy, and the cost is relatively high
