Embodiment Construction

[0048] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, not to limit the present invention.

[0049] The fire-fighting aerial ladder truck has a work bucket for manned aerial work. In order to ensure the safety of the workers in the work bucket, the work bucket must be kept horizontal during the movement of the boom. Therefore, in order to level the work bucket, it is necessary to detect the working bucket in real time. Rotation angle, and the detection value is required to be accurate enough. At present, the rotation angle of the working bucket is mainly detected by the inclination sensor, but the use of the inclination sensor mainly has the following disadvantages:

[0050] First, the inclination sensor detects the absolute angle of the working bucket, but what the le...

Abstract

The invention discloses a rotation angle detection device and high-altitude operation equipment, the rotation angle detection device comprises a gear rack hydraulic cylinder, a transmission shaft assembly and a detection assembly, the gear rack hydraulic cylinder comprises a cylinder body and a gear body accommodated in the cylinder body, and the transmission shaft assembly is arranged on the gear body in a penetrating manner and is fixedly connected with the gear body; the transmission shaft assembly is arranged on the cylinder body and can coaxially rotate along with the gear body, the detection assembly comprises an installation frame arranged on the cylinder body and a rotary encoder installed on the installation frame, and an input shaft of the rotary encoder is coaxially connected with the transmission shaft assembly. By means of the technical scheme, the actual angle needed by leveling operation can be directly detected without any angle change, so that the leveling precision of the working bucket can be improved, meanwhile, misoperation can be avoided, and the purpose of eliminating hidden dangers affecting the personal safety of operators is achieved.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery, and in particular relates to a rotation angle detection device and high-altitude operation equipment. Background technique [0002] The fire-fighting aerial ladder truck has a work bucket for manned aerial work. In order to ensure the safety of the workers in the work bucket, the work bucket must be kept horizontal during the movement of the boom. Therefore, in order to level the work bucket, it is necessary to detect the working bucket in real time. Rotation angle, and the detection value is required to be accurate enough. At present, the rotation angle of the working bucket is mainly detected by the inclination sensor, but the inclination sensor detects the absolute angle of the working bucket, and what the leveling control of the working bucket really needs is the relative angle of the working bucket relative to the boom, which leads to the Leveling accuracy is low. At the same...
