Horizontal wheel displacement adjusting method and displacement-adjustable horizontal wheel group

Abstract

The invention relates to displacement adjustment of a horizontal wheel of a crown block traveling mechanism, and discloses a horizontal wheel displacement adjusting method and a displacement-adjustable horizontal wheel group, concretely, a horizontal wheel is connected to a bracket through a wheel shaft, the wheel shaft is an eccentric shaft, the horizontal wheel is arranged at the lower end of the wheel shaft, a screw thread is processed on the outside of the upper end of the wheel shaft, the upper end of the wheel shaft is provided with a nut, and the lower end of the nut is provided with a flange plate; the bracket is provided whit a through hole at the mounting position of the wheel shaft, the nut is arranged on the through hole, and the screw thread is formed on the outside of the wheel shaft so as to be matched with the nut, in this way, vertical and horizontal displacement of the horizontal wheel is realized by rotating the wheel shaft; with the method provided by the invention, the practical rail range of the horizontal wheel is increased, service life of wheels and rails is prolonged, and cost of spare parts is reduced; and the horizontal wheel group is convenient to mount and detach and excellent in maintenance performance, the horizontal wheel can accurately guide the travel of a cart, the problem of rail gnawing is avoided, cost of production, use and maintenance is reduced, and the service life of the rail and the horizontal wheel is improved.

Description

technical field [0001] The invention relates to a component of a traveling mechanism of a crane, in particular to a method for adjusting the displacement of a horizontal wheel and a horizontal wheel set with adjustable displacement. Background technique [0002] The large-span bridge cranes and metallurgical cranes usually use double-rim wheels as the traveling mechanism of the large-span bridge crane and the metallurgical crane. The function of the wheel flange is to guide and bear the horizontal lateral force during deflection operation. Because in actual production, due to various reasons, the crane will run skewed and cause serious wear between the wheel and the track, which is the so-called rail gnawing phenomenon. Due to severe wear and tear, some crane wheel workpieces have a service life of only a few months, and some crane rails have to be replaced in advance. On the other hand, the mechanism needs to overcome greater resistance during skewed operation, and the car...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the above-mentioned defects and at the same time solve the problem of frequent faults in the operation of large-span and large-tonnage cranes due to track installation errors and out-of-synchronization of the traveling motors of the large-scale cranes, which lead to running deviations. Provided are a horizontal wheel displacement adjustment method and a horizontal wheel set with adjustable displacement
