Coke oven heating gas pipeline cock system tool-type modular installation construction method

Abstract

The invention discloses a tool type modular installation and construction method of a coke oven heating gas pipeline cock system. The method comprises the following steps: S1, installing branch pipes on a coke oven gas main pipe; S2, adopting an equipment assembly platform to assemble the coke oven heating gas pipeline cock system; S3, adopting an installation vehicle to transport and accurately install the coke oven heating gas pipeline cock system, wherein the installation vehicle comprises a walking mechanism, a lifting mechanism and a fine adjustment platform; placing the assembled coke oven heating gas pipeline cock system on a roller wheel mechanism, transporting the coke oven heating gas pipeline cock system to the installation site by using the walking mechanism, lifting the coke oven heating gas pipeline cock system to a required height by using the lifting mechanism, and using the fine adjustment platform to precisely adjust the coke oven heating gas pipeline cock system along the horizontal direction and the longitudinal direction and perform precise adjustment on the rotation, around the axis of the system, of the coke oven heating gas pipeline cock system. The tool type modular installation and construction method realizes modular horizontal transport and vertical transport as well as accurate positioning of equipment.

Description

technical field [0001] The invention belongs to the technical field of coke oven heating gas equipment installation, and in particular relates to a tool-type modular installation method for a coke oven heating gas pipeline cock system. Background technique [0002] The installation of the coke oven gas heating system is an important link in the installation and construction of the coke oven. Due to factors such as many equipment components, small installation space, tight construction period requirements, and many upper and lower cross operations, the installation work is difficult and the installation accuracy control is difficult. quality is difficult to guarantee. [0003] The main difficulties in the installation of the coke oven gas heating system are as follows: [0004] 1. To open the coke oven gas main pipe, the conventional method is to locate the installation center of the coke oven gas main pipe with the help of the center line of the coke oven transferred from t...

Problems solved by technology

[0004] 1. Open the coke oven gas main pipe. The conventional method is to locate the coke oven gas main pipe installation center with the aid of the centerline of the coke oven transferred from the previous process and use the theodolite, and then pull through the steel wire (tighten both ends with turnbuckle screws to ensure that the steel wire is tight) Tight, not sagging), auxiliary positioning, at the same time, use the center line of the side carbon 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 gas main pipe. Under the influence of shrinkage, if a certain tension is applied to the long steel tape, the length of the tape will be larger or smaller than the standard size. This part of the error must be allocated to the distance between each branch pipe through calculation. For example, a coke with 65 holes and a carbonization chamber distance of 1400 mm Furnace, the distance between the centerlines of the carbonization chambers on both sides is 89600 mm, and the length of the long steel tape is 89625 mm under a certain tension. , and then record the readings one by one (0, 1400.39, 2800.75, 4201.14, 5601.53...), and then release the opening line through the center line of the carbonization chamber. , may be damaged due to other welding constructions, and the steel wire of the cleaning rod is also easy to sag or be tightened by the turnbuckle until it breaks;

[0005] 2. The coke oven heating gas pipeline cock system includes the adjustment cock, connecting short pipe, orifice plate box and exchange cock from bottom to top. The pressure must be the same, and the construction personnel need to move around the equipment to complete the tightening of the bolts one by one. The labor intensity of the construction personnel is high and the efficiency is low;
