Description

Mechanical equipment base center adjusting device

Technical Field

The utility model relates to a device, especially a mechanical equipment base center adjusting device for construction.

Background

With the continuous development of the petrochemical industry in China, petrochemical devices of petroleum, medium petrochemical industry and medium sea oil are continuously built and expanded in recent years, particularly, the coal chemical industry in China is rapidly developed, coal-to-liquid and coal gasification devices and the like are pulled out in the west, and mechanical equipment is continuously increased. The mechanical equipment alignment procedure is unchanged, and from the beginning of installation, equipment base center alignment, foundation bolt hole grouting, secondary alignment, secondary grouting, cavity filling and final alignment are carried out. Each piece of machinery undergoes multiple alignments. The alignment precision of the center of the mechanical equipment base directly influences the position precision of the equipment and the installation precision of a process pipeline, and even influences the production operation of the whole device; the alignment speed of the mechanical equipment base center directly influences the construction period.

The center adjustment of the traditional large mechanical equipment base generally adopts a method of hanging a chain, and the method comprises the following specific steps:

1) after the mechanical equipment is installed, the center of the equipment base is adjusted to be superposed with the center line of the foundation;

2) selecting different models of chain blocks for equipment with different weights and sizes;

3) selecting a structure or a foundation which can fix the inverted chain near the equipment at the position of the equipment needing to be adjusted, hanging the inverted chain on the structure or the foundation, and hooking the inverted chain at the position which can be hooked at the bottom of the equipment by using an inverted chain hook;

4) the equipment base is adjusted by tensioning the chain block, so that the center of the foundation is coincided with the center of the equipment base, 2 or 3 chain blocks are sometimes required to be hung at the same time, and the equipment cannot deflect towards one direction by pulling.

The method requires a large number of constructors and construction tools; the hanging position of the chain block is not easy to find, and the hook at the end of the chain block connected with the equipment is easy to damage the anticorrosive coating of the equipment body, so that the repair cost of the anticorrosive coating is increased, and the construction period is delayed; the hook is easy to slip off in the pulling process, is easy to hurt people and is unsafe; the centering precision of the equipment base and the foundation is not well controlled, and once rework occurs, the construction period is delayed; the increase of alignment personnel and machines increases the construction cost and reduces the economic benefit of construction units.
