Automatic tracking method and automatic tracking device of lifter

Abstract

The invention discloses an automatic tracking method and an automatic tracking device of a lifter. The automatic tracking device comprises an optical tracking head, an electronic circuit panel, a photoelectric inductor, an X-axis sliding plate, a Y-axis sliding plate and a light source, wherein the optical tracking head is internally provided with a spherical detector, the spherical detector is clamped by a sliding clamp and rotates in a concave internal groove of the sliding clamp; the electronic circuit panel is parallel to a daylight opening, and included angles between the electronic circuit panel and the ground and between the photoelectric inductor and the ground are changed along with the rotation of the spherical detector; the X-axis sliding plate is driven by an X-axis driver, the Y-axis sliding plate is driven by a Y-axis driver, and the X-axis sliding plate and the Y-axis sliding plate poke a poke rod to scan an object positioned on the ground; and the light source is seated on a lifting ring on which an article is lifted to send a signal to the photoelectric inductor. The automatic tracking method and automatic tracking device which are disclosed by the invention have the beneficial effects that a person stands in front of the lifted article and remotely controls an overhead travelling crane when the article is lifted, then the overhead travelling crane automatically moves to be above the lifted article, in such a way, the integral lifting process can become simple, high automation degree is achieved, and the safety in production is facilitated.

Description

technical field [0001] The invention relates to hoisting technology, in particular to a method and a device for automatically finding lifting rings for a crane hook hoist. Background technique [0002] In the prior art, the movement of the crane hoist of the girder crane is judged by manual visual observation. Either the driver of the crane operates in the high-altitude operation room of the crane, or the operator holds a wired operation box on the bottom and slowly follows The movement of the crane hoist follows the ground, and the degree of automation is very low. [0003] People hope that when hoisting objects, they stand in front of the objects to be hoisted, remotely control the crane hoist, and then the crane hoist will automatically run to the top of the objects to be hoisted, so that the whole hoisting process will become simple. [0004] The above assumptions have not seen a technological breakthrough until now. Contents of the invention [0005] The object of t...
