Description

Technical Field

[0001] The utility model relates to the technical field of monorail cranes, in particular to an anti-collision device for monorail cranes. Background Art

[0002] Monorail crane is a commonly used lifting equipment. Monorail crane mainly uses electric motor to drive the lifting mechanism to walk on the track system, lift the goods and transport them to the designated location. It is mainly used for indoor transportation and lifting heavy objects. It is suitable for various light and heavy loads, short-distance transportation, and frequent lifting occasions. The existing Chinese patent publication number is: CN213384228U, which provides a monorail crane locomotive with anti-collision protection function, which includes a monorail crane rail, a pulley block and a car box. The pulley block slides on both sides of the monorail crane rail. The car box is connected to the pulley block through a suspension device. A travel switch is provided on the outer side of the front wall of the car box. The travel switch is connected to the control box of the locomotive through a wire. By setting two travel switches in front of the locomotive, the travel switches are connected to the control box. When the monorail crane locomotive hits equipment or people during operation, the travel switches are activated, and the monorail crane locomotive automatically shuts down and stops. This practical monorail crane rail protection solves the problem that the locomotive does not stop when the monorail crane locomotive touches equipment or people during operation, causing damage to people or equipment. It greatly improves equipment and personal safety. The device is simple, improves transportation efficiency and safety, and achieves good use effect. The above anti-collision device still has the following problems when in use: the outer ring of the above monorail crane locomotive is not provided with any anti-collision device, and the above travel switch will not be turned on until it is hit, and the monorail crane will not be turned off, but the impact generated at this time has caused certain damage to the monorail crane, and will also cause certain damage to the hit object or person. The "monorail crane anti-collision device" disclosed in the application number "CN202311188616.1" solves the problem that the outer ring of the above-mentioned monorail crane locomotive is not equipped with any anti-collision device through a specific technical structure setting, and the above-mentioned travel switch will not be turned on until it is hit, and the monorail crane will not be shut down, but the impact generated at this time has caused certain damage to the monorail crane, and will also cause certain damage to the object or person hit. However, the device still has some problems, such as: it uses multiple buffer components in conjunction with buffer plates to deal with the collision of the carriage, but the structures in the multiple buffer components, such as springs, are easily damaged, and it is more troublesome to replace new springs and then install them after damage. The shock absorber rods at the spring installation position are rotatably connected to the movable block and the magnetic block. When removing the damaged spring and installing a new spring, the connection needs to be removed, and the operation steps are many and inconvenient for staff to use. Utility Model Content
