Problems solved by technology

However, due to the asymmetry of the trolley body, the center of gravity of the empty car (on the curved track section) and the heavy car (on the horizontal track section) do not coincide, so the thrust on the curved track section does not exceed the center of gravity, resulting in a The failure rate of the cold machine is high

Embodiment Construction

[0023] The body of the ring cooler machine is shown in Figure 1. Because the track of the trolley is a circle, the material-bearing surface of the trolley body 1 is trapezoidal, and the upper part of the trolley body is provided with a grate plate 4 to form a trapezoidal material-bearing surface, and a lug 5 is installed on one waist of the trapezoid. Wheel 3 is installed on a waist. The inner and outer slewing frame beams on both sides of the trolley are equipped with guard plates (the weight of the guard plate is not borne by the trolley, so it is not shown in Figure 1). When the trolley distributes materials evenly, it can be considered that the pile of sintered materials has a cross-section of Trapezoidal cylinder, the center of gravity of the material pile passes the geometric center of gravity of the trapezoidal material receiving surface of the trolley. The design of the lug position of the trolley body is based on the heavy vehicle. The eccentric weight of the trolley...

Abstract

A method for adjusting loop wheel machine centre of gravity to decrease phenomenon of track being bitted by wheel includes using í SOLID WORKS íÀsoftware to set up model for body of loop wheel machine for calculating out centre of gravity on irregular loop wheel machine body to confirm adjustment amount and direction for centre of gravity body of loop wheel machine , improving structure of loop wheel machine according to calculating result to let pullback thrust action line overpass centre of gravity on body of loop wheel machine .

Description

technical field [0001] The invention relates to a method for avoiding or reducing wheel deviation, rail gnawing and derailment by rationally adjusting the gravity center of a trolley of a sintering ring cooler, and belongs to the technical field of sintering equipment. Background technique [0002] The temperature of the sinter used in blast furnace smelting is about 700-800°C when it is unloaded from the tail after being sintered by the sintering machine, but the actual smelting temperature should drop to about 150°C. is a very important part. One of the most commonly used methods for cooling sinter is to use a ring cooler (that is, a ring cooler) for external cooling. The ring cooler is composed of a number of trolleys fixedly connected to each other. The sintering ore, the trolley and the inner and outer rotary frame beams are fixed, the wheels of the trolley are supported on the circular track, the driving device drives the rotary frame beam, the rotary frame beam and t...
