Embodiment Construction

[0026] Such as Figure 1-5 As shown, a wheel alignment correction process includes wheel levelness detection and repair and wheel verticality detection and repair. The specific operation steps are as follows:

[0027] S1, the detection of wheel level and verticality: use the level detector to take the track center line as the reference line, detect the level value of each wheel 1 of a wheel group and record the detection point data, determine the deflection of each wheel 1 through the detection data, The detection of the levelness of the wheel 1 is mainly to measure the deflection of two symmetrical wheels A1 and B1, that is, to measure the deflection distance d1= 149.5mm, d2=151.5mm and d3=213.5, d4=212, the deflection is (d1-d2)=-2 and (d3-d4)=0.3 respectively;

[0028] Use a frame-type spirit level vertically close to the outer side of each wheel rim of the wheel group to detect the verticality one by one and record the data of the detection points, and determine the incli...

Abstract

The invention discloses a wheel alignment correction process, including wheel levelness detection and repair and wheel verticality detection and repair, the specific operation steps are as follows: S1, wheel level and verticality detection; S2, wheel removal; Repair the level or verticality of the wheel with the plate; S4, debugging; S5, bonding the backing plate. In the present invention, the bearing at one end of the wheel shaft and the bearing box are horizontally displaced by pasting a backing plate on the positioning iron, and the wheel is driven to rotate with the center of the other bearing as the center of a circle, so that a proper distance is maintained between the rim of the wheel and the rail. So as to solve the problem of "rail gnawing" of the wheel, and fundamentally solve the problem of the deviation of the assembly reference of the wheel assembly. "Rail gnawing" phenomenon occurs again, the operation process is simple, fast, and the cost is low.

Description

technical field [0001] The invention relates to the field of crane deviation correction, in particular to a wheel positioning deviation correction process. Background technique [0002] Overhead cranes have more or less inevitable problems such as deformation of structural parts and out-of-tolerance assembly benchmarks in the process of manufacturing, sub-packaging, transportation, hoisting, and installation. Especially after these cranes have been used for a certain period of time, due to many problems such as out-of-tolerance track installation benchmarks and frequent operation due to irregular settlement of the factory building, there will be varying degrees of large or small trolley running deviation and gnawing on the rails. [0003] The potential safety hazards caused by crane deviation and gnawing on rails are as follows: 1) The deviation of crane wheels leads to rail gnawing of guide wheels or wheel rims, shortening the service life of guide wheels and wheels. 2) Ac...
