Coke oven heating gas pipeline branch pipe intersecting line distance measuring and setting-off device

Abstract

The invention discloses an intersecting line ranging and releasing device for a coke oven heating gas pipeline branch pipe. The intersecting line ranging and releasing device for the coke oven heating gas pipeline branch pipe comprises line throwing devices and a line releasing device; a pair of line throwing devices, each of which is composed of a bracket, a straight line marking instrument arranged on the top of the bracket in a sliding manner and a ranging baffle arranged on the top of the bracket, are arranged at the two ends of a coke oven heating gas main pipe respectively; projecting lines of the straight line marking instruments of a pair of line throwing devices are both coincided with the center line of the coke oven heating gas main pipe; the line releasing device is composed of a plurality of parallel branch pipe line releasing dies with the outside diameter being consistent with that of the branch pipe, a connecting rod for connecting all the branch pipe line releasing dies, a range finder which is rotationally installed on the connecting rod and a supporting plate which is installed on the connecting rod and used for supporting the range finder; the distance between two adjacent branch pipe line releasing dies is the same as that between two adjacent branch pipes; and reference lines are arranged on the upper surfaces of the branch pipe line releasing dies in the diameter direction respectively and are collinear. The intersecting line ranging and releasing device is short in time consuming by releasing a line and accurate in reading.

Description

technical field [0001] The invention belongs to the technical field of installation of coke oven heating gas equipment, and in particular relates to a range-finding and setting-out device for intersecting lines of branch pipes of coke oven heating gas pipelines. Background technique [0002] The coke oven heating gas main pipe is opened. The conventional method is to use the theodolite to locate the installation center of the coke oven gas main pipe with the help of the center line of the coke oven handed over from the previous process, and then pull through the steel wire (tighten both ends with turnbuckle screws to ensure that the steel wire is tight) , not sagging), auxiliary positioning, and at the same time, use the center line of the side charcoal and the front line to locate the installation center of the branch pipe, and use a long steel tape to draw the opening lines one by one in the coke oven heating gas main pipe. Under the influence of thermal expansion and cont...

AI Technical Summary

Problems solved by technology

The offset of the cock caused by the excessive positioning error of the opening line and the line will seriously affect the normal operation of the coke oven exchange transmission device. In production, it will not only affect the normal production of the coke oven, but also increase the strength and difficulty of maintenance inspection virtually.
