Sensing equipment and method for automatic grabbing process of tower crane lifting hook

Abstract

The invention provides sensing equipment and method for an automatic grabbing process of a tower crane lifting hook. The sensing equipment comprises a controller, an automatic lifting hook, a lifting hook driving mechanism, a visual sensor and a sensor driving mechanism; the automatic lifting hook is connected with the lifting hook driving mechanism, the visual sensor is connected with the sensor driving mechanism, and the lifting hook driving mechanism, the sensor driving mechanism and the visual sensor are all connected with the controller; when the controller controls the automatic lifting hook to move through the lifting hook driving mechanism, the controller further controls the visual sensor to move along with the automatic lifting hook through the sensor driving mechanism and controls the visual sensor to collect visual sensing signals towards the area where the automatic lifting hook is located, so that the automatic lifting hook is controlled to grab goods according to the visual sensing signal. The safety accident rate of tower crane hoisting can be effectively reduced.

Description

technical field [0001] The present application relates to the technical field of intelligent tower cranes, in particular to a sensing device and method for the automatic grabbing process of a tower crane hook. Background technique [0002] With the development of the construction industry, the degree of mechanization of construction has been increasing year by year. As a machine that can transport materials vertically and horizontally, tower cranes (tower cranes for short) It has been widely used in the construction industry due to its large range and other characteristics. [0003] However, due to the high height of traditional tower cranes, there are many blind spots for tower crane drivers, and many operations must be completed by ground commanders. Tower crane drivers need to repeatedly coordinate and communicate with tower crane drivers through walkie-talkies in order to hoist materials. In this way, due to the super high lifting distance of the tower crane and the exi...

Problems solved by technology

[0003] However, due to the high height of traditional tower cranes and many blind spots for tower crane drivers, many operations must be completed by ground commanders. The hoisting materials of tower crane drivers require repeated coordination and communication with tower crane drivers through walkie-talkies. In this way, due to the super high lifting distance of the tower crane and the existence of blind spots in the line of sight, the hooks of the tower cranes often occur inaccurately or the hooks fall off, causing materials to scatter, injuring ground staff such as cablemen and conductors, and causing safety accidents

[0004] Although with the development of video surveillance technology, some technologies collect images of hooks by installing zoom cameras on the boom to reduce safety accidents, but manual zooming will affect the normal hoisting operation of tower crane drivers, and automatic zooming often causes focus loss. The problem of blurring the picture and making it impossible to see clearly, the above-mentioned technique of installing a zoom camera on the boom is not effective in actual use
