Problems solved by technology

Install or replace the steam drum after the high-rise steel structure is closed. If a large crane is used to directly place the steam drum in place, the roof of the steam drum at the steelmaking tower and the roof steel structure at the crane station of the low-span factory building must be removed for construction. The cycle is long and directly affects the production of the production line, and at the same time, the cost of engineering investment increases

Embodiment 1

[0034] Such as Figure 1-8 As shown, the pipe belt machine threading and pulling device of the present invention comprises a belt 1 after cutting, a splint 2, a connecting bolt 3, and a shackle hole 4; Waist trapezoidal shape to ensure the smooth introduction of the cut belt 1 into the tubular entrance section; the cut belt 1 is connected with the shackle hole 4 through the splint 2, and the cut belt 1 is formed by the formal belt according to the isosceles Trapezoidal cutting, the width of the upper opening after cutting is greater than the width of the splint 2, and the size is 400mm. The splint 2 is composed of two upper and lower splints 2 with a thickness of 16-20mm, which is in the shape of a trapezoidal arc. The connection method adopts six groups of bolts of M20, and the hole diameter The connection to the shackle is aperture.

Abstract

The invention relates to a method for converter steam drum emplacement after workshop closing. A hoisting point is arranged on a roof beam right above a steam drum emplacement position, three sets of winch units are utilized, and an alley-oop form is employed to complete vertical lifting and horizontal translation of the steam drum, thus finishing steam drum emplacement work. The construction steps include: 1. structure reinforcement; 2. lifting device setting; 3. steam drum horizontal cross; and 4. steam drum hoisting. The method can realize steam drum emplacement work at high-rise frame without adopting a large crane and removing a roof steel structure, reduces the production influence on a production line, lowers the project investment, and ensures the engineering construction progress.

Description

technical field [0001] The invention relates to a method for placing a converter steam drum in place after a factory building is closed. Background technique [0002] The steam drum equipment is one of the key equipment of the steelmaking converter and the core equipment for maintaining the water vapor cycle in the vaporization system. It is usually installed on the high-level platform of the steelmaking tower. The weight is about 40t, and the converter maintenance crane cannot directly complete the placement work of the steam drum. In the construction of similar domestic projects, the method of synchronous hoisting with the steel structure of the steelmaking tower is usually adopted to complete the installation of the steam drum body equipment. Install or replace the steam drum after the high-rise steel structure is closed. If a large crane is used to directly place the steam drum in place, the roof of the steam drum at the steelmaking tower and the roof steel structure at...
