Mechanical regulating device for big spring at the lower part of cart-type coke oven

Abstract

A mechanical regulating device for a big spring at the lower part of a cart-type coke oven comprises a regulating mechanism, a bracket mechanism and a lifting mechanism; the lifting mechanism comprises a lifting cart which is hinged with a rotating tray; the bracket mechanism comprises a bracket which is fixed to the rotating tray and rotates along with the rotating tray; the regulating mechanism comprises a speed reducer, a flange type coupling and a cross coupling; the speed reducer is connected with a bushing by means of the flange type coupling and the cross coupling; the advantages are as follows: the mechanical operation instead of manual operation is performed in the regulating work; a movable mechanism relying on the raising / descending function of a cart is capable of effectively solving the problem of inconvenient alignment caused by tiny difference of the elevation of the big spring at the lower part of the coke oven; the regulating mechanism is capable of rotating for 180 degrees on the lifting cart by means of the rotating tray and a positioning shaft, so that the regulating mechanism can be moved without barriers in a narrow flue corridor of the coke oven; therefore, nearby, safe and reliable electrification is facilitated, and inconvenience caused by the device dragging a big bundle of cable during moving can be avoided.

Description

technical field [0001] The invention relates to the technical field of metallurgical machinery, in particular to a mechanized adjustment device for large springs at the lower part of a cart-type coke oven. Background technique [0002] The large springs at the lower part of the coke oven are located on both sides of the coke oven plate, and are hidden deep in the exchange switch. The traditional tool for pressure adjustment is the extended artificial hexagonal guide tube wrench. 6 to 8 people stand in a narrow smoke The temperature of the coke oven flue corridor is as high as 50-70°C (the floor temperature is set above 70°C), which is labor-intensive, low in efficiency, and low in adjustment accuracy. Although the elevation of the large spring in the lower part of the coke oven is relatively good, and the consistency of the operating point is relatively good, the effective width of the flue corridor is limited (taking the JN43-80 coke oven as an example, the effective width...

[0002] The large springs at the lower part of the coke oven are located on both sides of the coke oven plate, and are hidden deep in the exchange switch. The traditional tool for pressure adjustment is the extended artificial hexagonal guide tube wrench. 6 to 8 people stand in a narrow smoke The coke oven flue corridor temperature is as high as 50-70°C (the floor temperature is set above 70°C), and the labor intensity is high, the efficiency is low, and the adjustment accuracy is low

Although the elevation of the large spring in the lower part of the coke oven is relatively good, and the consistency of the operating point is relatively good, the effective width of the flue corridor is limited (taking the JN43-80 coke oven as an example, the effective width of the operation is only 80cm), and the flue corridor needs to be frequently Carry out thermal engineering measurement and adjustment, point inspection and other operations
