Overhead Bridge Crane need Intelligent Technology and Internet

BY Dongqi Crane IN Overhead Crane Blog

Replace the square design and manufacture wonderful skill of Bridge Crane, performance optimization of parts and complete the saving energy and reducing consumption, and make breakthrough in key technology of lightweight, is not only the inevitable trend, the crane industry is to realize the green yield the overall index of the crisis in our country.

Crane broadly applied in metallurgy with the transportation and logistics industry shipbuilding industry and pillar industry of national economy, in economic construction need of carrying forward with no or lack of. Bridge crane as a model of the lifting machine quantity bedding face is wide, more broad in the practical application The characteristics of the roots sexual with his general. So a change in traditional bridge crane design and manufacturing technology, beautify the whole machine performance and achieve saving energy and reducing consumption, to break a lightweight hub technology, is not only the inevitable trend, the crane industry is realizing green production in our country overall index.

Lightweight technology

Bridge lightweight skill new lightweight crane bridge usually adopt four beam structure form, Its main girder used slant narrow flange all rail welding box beam structure, the small wheel pressure course track directly to the upper cover plate and the main weld on the web.

Compared with conservative half partial track model, adopt the partial rail box beam by main force, web and vice web thickness extraction is smaller than the main web, and can write off half a partial rail small box girder external overflow clapboard Acceptance of the content structure, can obviously improve the girder on cover plate welding deformation and the deformation of the waves, and the welding under torsion deformation is small. Large tonnage box beam is width beam, so the walking board can be omitted . with inflexible crane using clamp fixed orbit different , lightweight crane trolley track acceptance of square steel (or flat) directly welding on the main girder, can make the orbit of box beam and the overall structure, subjected to load all the way, on the strength and stiffness of main girder, greatly reduces the girder of the main girder height.

By admitting the four bridge frame structure model , All partial rail welded box girder orbit, reasonable selecting materials, using beam modular design ideas, so can make the crane from structural solution to achieve the purpose of the light.

Lightweight technology of trolley frame

Square lifting trolley frame adopt statically indeterminate structure of organization, choose parts craft ancient, insufficient place beautification, the resulting lifting mechanism large and clumsy The load lifting mechanism of the car frame is used more by two beam More than more girder and reinforced steel welding into statically indeterminate rigid frame structure model, framework above shall lay thick steel plate. Thus, the radical trolley frame structure not only has the high risk cost structure complex welding strength Ills such as rigidity, and easy to render the wheel at 3 o 'clock on wheel pressure distribution is not uniform Wheel gnawing rail, affect the crane safe sex and life.

Lightweight crane to accept three pivot statically determinate supporting mode of i-section girder car frame, its beams to snatch block beam This type of car frame in the vertical deflection is filling the rigidity, to reduce the vibration of the lifting heavy objects in terms of degree of rotation, there is a flexible way, approve the car suffered a certain amount of rotational deformation, to ensure that the four-wheel fulcrum to adapt to the deformation of main girder

Lightweight technology of hoisting mechanism

Beautify the new hoisting mechanism placed after take I-beam, drum through a roller bearing and a gear reducer Jane bearing half horizontal arrangement between the two wheels beam. Accelerator spline input shaft end are connected to the drum flange plate after rigid cone took over, mechanical and electrical by flange on the accelerator box. The lifting mechanism only a speed up Jane for support A hinged support and a roll bearing seat connected to the car frame beam, bearing model easy to clear. This structure through the process of transmission chain of beautification, advance the hoisting height increase the space utilization, completed the lifting structure compact car group The purpose of the parts highly significantly low.

Reducer setting model should not only guarantee the transmission of strong, and to meet the needs of lightweight crane hoisting mechanism layout is compact, lightweight trolley crane space does not have the traditional trolley platform is used to install components, its beam is narrow and small rigidity, therefore need to optimize the radical set the content of slow, contraction to reduce the transmission of vibration transmission chain size.

Through the metal structure link technical seminars and lightweight beautification design, novel crane product quality can be cut by 20% ~ 20%, height is 10% ~ 30%, low energy consumption can be a low 10% ~ 30% at the same time, adopt lightweight technology crane can reduce workshop building height, saving expenses for heating and lighting, obviously decrease the comprehensive use of capital.
