Method for connecting aluminum electrolysis multifunctional overhead crane orbit telescopic seam

Abstract

The invention relates to an improved device in aluminium electrolysis industry, in particular to an aluminium electrolysis multifunction crown block rail expansion gap connecting method. The invention comprises a cement beam, a rail, a coattail-shaped trough, a fixed bolt, and an L-shaped rail expansion joint. The connecting method of the rail expansion gas is that two rails with L-shaped cut at the ends are mutually overlapped and sleeved in the coattail-shaped trough which is fixed on the cement beam by the fixed bolt. The invention eliminates the phenomenon of the rail gnawing of crown block caused by rail joint crushing; slight clearance is arranged on the side surfaces of the trough and the rail and the top surface of the rail base, so as to prevent the transverse staggering of the rail and ensure the free expansion when the rail is expanded by heat, solve the problem of the rail expansion gap coattail plate that the rail is not easy to slide or the rail is transversely staggered, and ensure the normal operation of the crown block. The aluminium electrolysis multifunction crown block rail expansion gap connecting method of the invention can be applied to the connection of the rail expansion gaps subject to heavy load, frequent and fatigue works in all industrial fields.

Description

technical field [0001] The invention relates to an improvement of equipment in the aluminum electrolysis industry, in particular to a method for connecting the expansion joints of the aluminum electrolysis multifunctional crane track. Background technique [0002] At present, rail cranes are generally installed in aluminum electrolysis plants for auxiliary operations of electrolytic cells. Each electrolysis plant is equipped with 6 electrolysis multifunctional combined units, which are mainly used to undertake daily operations such as pole change, aluminum tapping, edge processing, addition of insulation materials, busbar transfer, and installation and lifting of 130 electrolysis cells. [0003] The traveling track model of the multi-functional combined unit cart is QU100, with a total length of 4Km, and is respectively installed on the crane beams with an elevation of 6.75 on both sides of the two electrolysis workshops. The installation of the track adopts the traditiona...

AI Technical Summary

Problems solved by technology

[0008] 1. The compression area at the top of the wedge-shaped expansion joint is very small, and it is easy to crush and deform under the repeated heavy pressure of the crane

The deformed expansion joints are extruded along the joint surface under the stress of thermal expansion, which changes the technical parameters of the track and causes problems such as rail gnawing by the crane

[0009] 2. The original track pressure plate is mainly fixed by bolts. Under the action of the impact force generated when the multi-functional combined unit is walking, the nuts of the bolts are easy to loosen, causing the pressure plate to loosen or fall off, which cannot fix the track, resulting in Straightness and span exceed standard
