Description

Top support device and auxiliary correction device of crane girder

Technical Field

The utility model relates to an auxiliary assembly technical field of hoisting machinery especially relates to a top supporting device and supplementary orthotic devices of hoist girder.

Background

The crane is generally applied to industrial and mining enterprises at home and abroad, and the camber of the main beam is an important technical index of the crane according to the requirements of national relevant standards. GB/T14405-2011 general bridge crane and GB/T14406-2011 general portal crane stipulate that a crane girder needs to be provided with a certain upper camber value, and the main purposes of the crane girder are to improve the bearing capacity of the crane, improve the stress condition of the girder and resist downward deformation of the girder under the action of load, but the crane is manufactured or used, for example, when a trolley is in a midspan, under the rated load and the influence of factors such as environment and use working conditions, the girder has camber downwarping or side-bending deformation, the trolley gnaws a rail, the trolley climbs a slope, slides and the lifting capacity is reduced to influence normal use, the upper camber value is used as a main parameter of the girder, whether the upper camber value is reasonable and is ensured, and the service life of the crane is directly related. Meanwhile, the oblique pulling and oblique pulling in the using process of the crane can cause the side bending of the main beam and the gnawing of the rail. Therefore, if the main beam is not corrected in time and is downwarped or bent, once a problem occurs, accidents can be caused to endanger the safety of lives and properties.

Chinese patent application No. 201210040871.7, entitled "a crane main beam", discloses a correction device for correcting main beam downward deflection and lateral bending by using a steel strand and a shoring device, wherein the correction device is provided with a pushing structure in the middle of the shoring device, and the specific pushing structure can be a jack or a vertical plate. The defects are as follows: 1. the jack increases the complexity of the jacking device, is inconvenient to install and use, and is easy to cause oil leakage problem when the jack is pressed for a long time, so that the service life of the jacking device is influenced; 2. the vertical plate has poor stability, the actual top support device is difficult to ensure that the middle vertical plate is kept absolutely vertical after being installed, the stress condition of the vertical column is rapidly worsened due to slight inclination, and the vertical plate is easy to bend under huge pressure, so that the correction effect of the correction device is influenced; 3. this patent adopts bolt installation bottom clamp plate, all needs the workman to use spanner adjustment bottom clamp plate when carrying out the girder correction operation at every turn, and is not convenient enough.
