Abstract
The invention discloses a construction method for mounting rails of a buggy ladle and belongs to a construction method for mounting metallurgical equipment. The construction method is characterized by comprising the following steps of: selecting a group of embedded bolts at every 2 to 3 meters from various embedded bolts on a concrete foundation of the buggy ladle rail; respectively downwards threading along an original screw thread of each embedded bolt by using threading dies with the same specification; respectively screwing adjusting nuts to a threading section of front and rear embedded bolts; respectively sleeving various adjusting backing plates of which front and rear holes are correspondingly drilled in each group of embedded bolts and supporting the adjusting backing plates on each adjusting nut; screwing and rotating the adjusting nuts for aligning the levelness and the elevation; after each adjusting backing plate is aligned and qualified, carrying out firm spot welding on each adjusting bolt corresponding to a screw rod of each embedded bolt; then correspondingly placing steel rails of the buggy ladle on each adjusting backing plate; rechecking by using a measuring instrument; after the specification requirements are respectively met, firmly mounting the rails by using a rail hold-down plate and mounting nuts; and then secondarily grounting the rails of the buggy ladle. The construction method is safe and reliable in construction, so that the mounting quality of the rails of the buggy ladle is ensured.
Description
Technical field
The invention belongs to the construction method that metallurgical equipment is installed, especially relate to the construction method that a kind of ladle car track is installed.
Background technology
Domestic metallurgy industry steelmaking system is installed ladle car track, and the installation quality of invar hired car track requires high, is seated on the concrete foundation owing to ladle car track again; And the flatness on concrete foundation surface is difficult to be controlled in the code requirement; To ladle car track the installation quality problem of bringing is installed for the flatness of eliminating the concrete foundation surface, lays thick along the ladle car track direction usually during construction and be the long steel plate of 14mm, then this long steel plate carried out horizontal centering again; On long steel plate, ladle car track is installed; The long steel plate of this laying is installed the end back in ladle car track and is built in the back-grouting layer, the expense of not only taking a lot of work material, and also work efficiency is low.
Summary of the invention
The objective of the invention is to propose the construction method that a kind of ladle car track is installed, not only construction safety is reliable, guarantees the installation quality of ladle car track, and labor and material saving improves installation efficiency simultaneously, shortens installation period.
The objective of the invention is to realize like this: the construction method that a kind of ladle car track is installed; It is characterized in that each pre-embedded bolt on the ladle car track concrete foundation; Length direction along ladle car track is whenever selected one group of (each pre-embedded bolt of symmetry promptly) pre-embedded bolt at a distance from 2 meters-3 meters; With the screw die of same specification along the former screw thread of this pre-embedded bolt downwards (promptly direction) earthward all carry out mantle fiber; The length of this mantle fiber screw thread is 30-35mm, will be screwed to respectively with the adjusting nut of pre-embedded bolt same specification on the mantle fiber screw thread section of pre-embedded bolt before and after this, with correspondence bored front and rear gaps respectively regulate backing plate be set in respectively organize on the pre-embedded bolt and carriage on each adjusting nut; This length * wide * height of regulating backing plate is 300mm * 120mm * 14mm; Regulate backing plate with measuring instrument N2 spirit level to every and carry out the centering of levelness and absolute altitude through twisting adjusting nut, make the levelness of respectively regulating backing plate reach 0.3/1000mm, absolute altitude also meets the requirements; Each regulate the backing plate centering qualified after; The all corresponding screw rod spot welding with pre-embedded bolt of each adjusting nut is firm; Then buggy ladle rail correspondence is placed on and respectively regulates on the backing plate, recheck longitudinal centre line, gauge, the absolute altitude of ladle car track, the difference of height of two ladle car track of vertical equity degree and same cross section with measuring instrument again, all satisfy code requirement after; With track pressing plate and installation nut track is installed firmly, then ladle car track is carried out back-grouting.
The construction method that a kind of ladle car track proposed by the invention is installed, not only construction safety is reliable, guarantees the installation quality of ladle car track, and labor and material saving has improved installation efficiency simultaneously, has shortened installation period.
The construction method that a kind of ladle car track that at present combines accompanying drawing and embodiment that the present invention is proposed is installed is described further.
