Anti-collision device and method

Abstract

The invention relates to an anti-collision device and method, and belongs to the technical field of crown block electrical equipment and methods. According to the technical scheme, a left oblique laser detection switch (6) and a left vertical laser detection switch (11) are installed above the left end of an end beam of a low-span crown block (7), a right oblique laser detection switch (12) and a right vertical laser detection switch (11) are installed above the right end of the end beam of the low-span crown block (7), and a wireless transmitting circuit (10) is installed in a cab of the low-span crown block. And the wireless receiving circuit (3) is arranged in a cab of the high-span crown block. The anti-collision device has the beneficial effects that the laser detection switch is applied above the end beam of the low-span crown block, so that anti-collision detection within the 3L range of the central point of the low-span crown block is realized, the safety of cross operation of the high-span crown block and the low-span crown block is ensured, and the situation that equipment is damaged due to collision of the high-span crown block and the low-span crown block is avoided.

Description

technical field [0001] The invention relates to an anti-collision device and method, belonging to the technical field of overhead crane electrical equipment and methods. Background technique [0002] The crane is a kind of lifting equipment widely used by various industrial and mining enterprises. Many times, due to production needs, a high-span crane and a low-span crane are installed on the same span. The high-span crane runs on the high-span track, and the low-span sky The car runs on a low-span track. In actual production, crossover operations often occur. The high-span crane is hoisting, the hook head is at a low position, the low-span crane suddenly comes over, or the low-span crane is working, and the high-span crane is lifting heavy objects. Passing over the low-span crane will often cause collision between the high-span crane and the low-span crane. When the crane operator finds out, it will be too late to stop the emergency stop, which will cause great damage to t...

AI Technical Summary

Problems solved by technology

In actual production, crossover operations often occur. The high-span crane is lifting and the hook head is at a low position. The low-span crane suddenly drives over or the low-span crane is working, and the high-span crane is hoisting heavy objects. Passing above the low-span crane often causes collisions between the high-span crane and the low-span crane. When the crane worker finds out, it is too late for an emergency stop, which causes great damage to the equipment and poses a great safety hazard.
