Electric single-beam crane

Abstract

The invention provides an electric single-beam crane. The electric single-beam crane comprises a main beam, end beams are fixedly mounted on the outer surfaces of the two sides of the main beam, operation signal lamps are fixedly mounted on the outer surfaces of one sides of the end beams, and pulleys are fixedly mounted on the two sides of the outer surfaces of the lower ends of the end beam. Buffer air cushions are fixedly mounted in the middle of the outer surfaces of the lower ends of the end beams, a cable is movably connected to the outer surface of the lower end of the main beam, a running trolley is slidably connected to the outer surface of the lower end of the main beam, an electric hoist is fixedly mounted at the lower end of the running trolley, and rubber air springs are arranged on the outer surfaces of the two sides of the electric hoist. According to the electric single-beam crane, the hoisting position and the falling point position can be accurately positioned when large instruments and equipment are hoisted and moved, stable movement and accurate direction of the hoisting and falling points are ensured, the risk of wall collision is avoided, and the stability ofthe large instruments and equipment is ensured.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to an electric single-girder crane. Background technique [0002] The electric single-girder crane is a lifting device that is placed horizontally over the workshop, warehouse and stockyard for material lifting. The bridge frame of the electric single-girder crane runs longitudinally along the rails laid on the elevated sides on both sides, which can make full use of the space under the bridge frame for hoisting. It is the most widely used and the largest number of hoisting machinery, mainly composed of electric hoist, metal structure, cart running mechanism, power feeding device and electrical device. [0003] The existing patent (notification number: CN210340100U) is an energy-saving electric single-girder crane, including an I-shaped main beam, an end beam, a walking track beam, a walking trolley, an electric hoist, and a guiding pressure-dividing mechanism; Both sides are equipp...

AI Technical Summary

Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that at least the following problems in the prior art have not been solved: 1. The position of large-scale equipment cannot be accurately positioned when lifting, and when the lifting position is inaccurate, large-scale equipment cannot The moment it leaves the ground, it will shake violently, which will cause damage to the large-scale equipment; 2. The crane will shake and even hit the wall when moving the large-scale equipment; 3. The electric hoist moves laterally to both ends of the main beam. It is likely to hit the end beam and the wall at the boundary position, causing severe shaking of large instruments and equipment
