Method for fast detecting verticality of coke oven wall

Abstract

The invention provides a method for fast detecting the verticality of a coke oven wall. The method includes the following steps: 1. manufacturing a tool for fast detecting the verticality of a coke oven wall, calibrating a scale in a cross bar which is in the upper part of a plumb bob and defining the verticality error range of the wall body; 2. arranging 5 detection points at the coke oven wall body which has a detection segment which is defined as no higher than 1.2m in the longitudinal direction height and no longer than 20m in the transverse detection length; 3. cleaning the slurry in theupper part and side surfaces of the coke oven wall body, a measuring worker standing in the upper part of a to-be-measured coke oven wall body, placing the cross bar in the upper part of the plumb bobto the upper end of the coke oven wall body, adjusting the extending length of the cross bar, adjusting the extending length of the cross bar so as to make the connecting line of the plumb bob vertical, ensuring the edge of the plumb bob attaching closely to the side wall of the coke oven wall body; and 4. Observing the position relation between the scale on the cross bar and the edge in the upper part of the coke oven wall body, determining whether the verticality at the corresponding position of the coke oven wall body is within the error range. According to the invention, the method can accelerates the detection of the verticality in the construction process, is easy to implement and can reduce manpower. The method only requires one construction worker for completing the detection at the construction place.

Description

technical field [0001] The invention relates to the technical field of kiln construction, in particular to a method for quickly checking the verticality of coke oven walls. Background technique [0002] The number of coke oven walls is large and the height is large, and the verticality of the walls is strictly required in the specification. It is necessary to conduct multiple inspections during the daily masonry process, and after the daily masonry is completed, all furnace walls built on the day will be uniformly checked and accepted. To meet the overall verticality requirements of the furnace wall. This just involves multiple verticality measurements, and the workload is heavy, and regular measurement of verticality becomes an unavoidable time for operators to carry out masonry work. [0003] In conventional methods, each measurement group is generally composed of 2 people, 1 person on the furnace wall and 1 person below the furnace wall. After the line falls vertically,...

Problems solved by technology

However, when the furnace wall is high and long, it is difficult for the surveyors to reach the designated measurement point at the lower part, and it is necessary to go through a long path to reach the next measurement point, and it is necessary to have a springboard for the workers to walk on the lower part of each furnace wall

A lot of time was spent on verticality measurement and inspection work, resulting in reduced work efficiency
