Changing method of rotation track of mechanical equipment

Abstract

The invention discloses a changing method of a rotation track of mechanical equipment, and relates to the technical field of machining. The changing method of the rotation track of the mechanical equipment comprises the following steps: (1) jacking an upper platform; (2) disassembling a lower ring track; (3) mounting and preparing a new lower ring track; (4) mounting the new lower ring track; and(5) carrying out tailing in work. By a method of integral jacking and cutting and splicing, the problems that by a traditional method, assembling and disassembling are quite inconvenient, and too muchtime is consumed are solved; by cutting, a 60-degree included angle is formed between a cutting surface and a diameter direction, and it can be ensured that in a rotation process of an electric excavator, a roller can stably and purely roll on the surface of the new lower ring track and does not jump; and one end of the lower ring track is cut to be reversely splayed, a similar dovetail groove matching mode is adopted, matching precision is improved, the integral roundness after splicing is ensured, the connection stability of equipment is improved, and thus, the service life of the equipmentis prolonged.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a method for replacing a rotary track of mechanical equipment. Background technique [0002] The electric excavator is a kind of mining equipment. The upper and lower halves of the excavator move independently when turning. The upper and lower ring rails and roller devices are used to form a similar bearing system, so that the upper platform can rotate freely at any angle. During this process, the swivel lower ring rail bears all the mass of the entire upper part of the electric excavator. Although the material of the ring rail is forged high-alloy steel, the upper part has a large mass and complex working force, so wear is inevitable; the lower ring rail of the electric excavator is a full circle structure, which is sleeved on the outside of the rotary central shaft and the high-voltage collector ring. The fasteners such as the pressure plate are fixed...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for replacing the rotary track of mechanical equipment. By adopting the method of integral jacking and cutting and splicing, the problem of extremely inconvenient and time-consuming installation and disassembly of the traditional method is solved; The 60-degree angle with the diameter direction can ensure that the rollers can roll smoothly and purely on the surface of the new lower ring rail during the rotation of the electric excavator without jumping; by cutting one end of the lower ring rail into an inverted "eight" The font adopts a matching method similar to the dovetail groove, which increases the matching accuracy, ensures the overall roundness after splicing, improves the stability of the device connection, and thus prolongs the service life of the device
