Jib luffing angle detection device

Abstract

The invention relates to a jib luffing angle detection device comprising a box body, a dwang, an interlocking bar, an encoder, and a controller; the encoder is arranged in the box body; the dwang is connected with the interlocking bar; the interlocking bar is connected with a rotary shaft of the encoder; the dwang is arranged outside the box body and connected with a movable arm of the jib; the encoder is connected with the controller, converts the angular displacement formed by the rotary shaft into an electric signal, and sends the electric signal to the controller. The jib luffing angle detection device is simple in structure, easy to process, low in cost, and electric purchased parts are reduced in number, thus reducing the whole making cost; the jib luffing angle detection device is simple to install, low in field installation process requirements, has no clear installation size precision requirement, simple and fast in construction, low in labor cost, simple in electric re-wiringprocess, less in electrified debugging works, stable and reliable in operation, and accurate in real time data; the main elements are mounted in the waterproof and dustproof box body, so the jib luffing angle detection device is long in life.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and in particular relates to a detection device for a boom luffing angle. Background technique [0002] In the field of loading and unloading technology, arm-type bucket-wheel stacker-reclaimer, arm-type bucket-wheel reclaimer, arm-type stacker, ship loader, circular stockyard stacker-reclaimer and other equipment are often used in steel mills, metallurgy, cement , Power plants, port loading and unloading operations, the pitch mechanism and the boom are the main mechanisms of the equipment. During equipment debugging, maintenance, and operation, in order to accurately and reliably control the pitch changes of the boom, the boom pitch can be detected accurately and in real time. The angle or magnitude is especially important. In the prior art, the detection of the pitch angle of the jib of the above-mentioned equipment is generally performed by an absolute encoder and installed by a tradit...
