Abstract

The invention discloses a using method of a multifunctional hanging platform in blast furnace construction, and belongs to the technical field of blast furnace construction. The multifunctional hanging platform comprises a primary beam, a secondary beam, a platform plate, platform handrails, a furnace measuring shell center hole, an access hole, a lifting point and the like. The multifunctional hanging platform is arranged to solve a series of construction problems such as in-furnace water resistance, layout of welding facilities and measurement of a furnace shell center line. While achievingthe effect of protecting against rain, the multifunctional hanging platform provides a control point for furnace shell center measurement, the top of the platform is a storage position for welding tools, and the edge of the platform provides a hanging point for out-furnace construction. The multifunctional hanging platform has the advantages of being safe, reliable, and convenient in construction,and guaranteeing construction quality; and moreover, investment is less, functions are more, and operation is convenient.

Description

technical field

[0001] The invention belongs to the technical field of blast furnace construction, and in particular provides a method for using a multifunctional hanging platform in blast furnace construction, which is suitable for storing equipment used for blast furnace shell body installation and welding and preventing rainwater from entering the furnace shell Facilities, especially suitable for coastal areas and areas with harsh climate conditions. Background technique

[0002] 5500m 3 The shell of the blast furnace is a revolving steel shell with variable cross-section, which is composed of 25 welded coaming plates. The thickness of the steel plate is 60mm-110mm, and the elevation of the shell top is 52.2 meters. , and the refractory materials in the furnace are constructed simultaneously, and water is strictly prohibited inside the furnace body.

[0003] In the past installation of the blast furnace shell, a rain-proof shed was set up on the furnace shell. The conce...

Examples

Embodiment approach

[0019] 1. Production of multifunctional hanging platform

[0020] Draw the construction drawing of the hanging platform according to the diameter of the furnace shell, determine the size of each part of the platform, and make a hanging platform according to the construction drawing. The diameter of the platform is 4 meters larger than the diameter of the furnace shell. , and welding hoisting point 3 on the main beam, 5mm thick steel plate 4 is sealed and welded on the platform, and railings 5 ​​are set up around.

[0021] 2. Set the center hole for measuring the furnace shell, the access manhole

[0022] A ￠500mm manhole is set in the center of the hanging platform for the vertical line of the furnace shell center, that is, to measure the center hole 6 of the furnace shell; 4 access manholes 7 are set around the platform for welding personnel to enter and exit.

[0023] 3. Hanging platform installation

[0024] Use a crane to hoist the hanging platform as a whole on the uppe...
