Description

Technical Field

[0001] The utility model relates to the technical field of safe production, in particular to a safe production protection device for an overhead crane. Background Art

[0002] Overhead cranes, also known as traveling cranes, traveling cranes, cranes, and overhead cranes, are a general term for cranes, primarily used for vertical lifting and horizontal transport of heavy objects within a certain range. Some types of overhead cranes, also known as cranes, operate intermittently, meaning that the corresponding mechanisms for retrieving, transporting, and unloading materials alternate within a single cycle. Cranes are becoming increasingly widespread in the market. Accidents often occur when lifting or traveling with loads without outriggers, and their speed is faster than crawler cranes. They offer stable operation, a large lifting capacity, and can travel within a specific range. However, the road must be smooth and firm, the tire pressure must meet requirements, and the crane must not exceed 50 cm above the ground. Long-distance travel with a load is prohibited. To ensure operational safety, lifting operations without outriggers is generally prohibited in China. Wire ropes used with cranes include phosphate-coated, galvanized, and smooth-surfaced wire ropes. Bridge cranes are lifting equipment used horizontally above workshops, warehouses, and material yards to lift materials. Because its ends rest on tall concrete columns or metal supports, it resembles a bridge. The bridge crane's girder runs longitudinally along tracks laid on elevated platforms on either side, fully utilizing the space beneath it to lift materials without being obstructed by ground-based equipment. It is the most widely used and numerous type of lifting machinery.

[0003] Patent document with application number 2021227650738 discloses a safety production protection device for an overhead crane, including a gantry, a movable lifting assembly under the gantry, a lifting assembly under the lifting assembly, a second telescopic assembly connected between the lifting assembly and the lifting assembly, and a first telescopic assembly at both symmetrical ends of the lifting assembly, one end of the two first telescopic assemblies is respectively rotated and arranged at the two ends of the gantry, and a controller is installed on the gantry. The utility model is provided with first telescopic assemblies distributed on both sides of the lifting assembly. When the gantry moves on the track, the two first telescopic assemblies will share the force acting on the second telescopic assembly. At the same time, the telescopic nature of the first telescopic assembly allows the lifting assembly to move on the slide rail, thereby solving the problem that the existing telescopic sleeve has no protective device, causing the second telescopic assembly to deform.

[0004] Although the above-mentioned utility model arranges first telescopic components symmetrically distributed on both sides of the lifting component, when the gantry moves on the track, the two first telescopic components distribute the force acting on the second telescopic component, and at the same time, the lifting component can be moved on the slide rail due to the retractability of the first telescopic component, thereby solving the problem that the existing telescopic sleeve has no protective device, which causes the second telescopic component to deform. However, there is a shortcoming that when the device is in use and moves to different positions, the auxiliary moving device at the bottom has not been changed and optimized, which may cause certain inconveniences during movement.

[0005] Therefore, it is necessary to install an adjustable anti-slip rail assembly at the bottom of the device, so that when using this device, by installing the overhead lifting device on it and moving it, it can be more stable and smooth, avoiding jamming or vibration when moving to the limit plate, which will bring certain risks to the staff on top and the transported objects.
