Description

Technical Field

[0001] The utility model relates to a movable bracket for installing a shore bridge crane beam anti-collision laser sensor, belonging to the technical field of shore bridge crane protection equipment. Background Art

[0002] Due to environmental issues, the surface of the anti-collision laser sensor of the shore bridge crane beam is easily attached to dust and needs to be wiped and cleaned frequently. The existing laser sensor is installed at the bottom of the pole through a fixed bracket. When cleaning the laser sensor, it is necessary to first separate the fixed bracket where the laser sensor is installed from the beam connection, and then lift the fixed bracket and the sensor as a whole to the beam for cleaning. The fixed bracket is connected to the fixed support corresponding to the beam through two pins. When removing the pins, the operator needs to lean out of the beam guardrail to operate, and the operating space is small, which is not convenient for disassembly and installation. When removing the fixed pin, it will also be affected by the friction and structural stress of the pin hole, which is very difficult to remove and not convenient for installation. Because the bracket structure of the laser sensor is difficult to disassemble and time-consuming, it requires the cooperation of 3 people during disassembly, and it takes 2-3 hours to disassemble and clean once. Each shore bridge crane has two beam anti-collision sensors on the left and right sides. It takes half a day to clean once, and the maintenance efficiency is very low. In addition, when operating, the operator needs to lean out of the beam guardrail to operate, and the tools used also have the risk of falling, which poses a great safety hazard.
