Mounting construction method of liner plates during mounting large-scale precision equipment

Abstract

The invention provides a mounting construction method of liner plates during mounting large-scale precision equipment, which comprises the following steps of: (1) processing an equipment base; (2) setting temporary liner plates, arranging hoisting equipment, mounting the equipment base on the temporary liner plates, adjusting the coordinate position, the height and the levelness of the equipment; (3) mounting liner plates: necessarily arranging liner plates at both sides of an anchor bolt of the equipment, supporting the liner plates on the bolt which is directly supported on the equipment base, adjusting the liner plates to support the bolt so that the horizontal plate and the equipment base are stably and firmly attached and monitoring the central line, the elevation and the levelness of the equipment in a liner plate mounting process; (4) primarily grouting: making an anchor bolt die on the periphery of the anchor bolt of the equipment, grouting and fastening the anchor bolt of the equipment after grouting reaches the strength requirement; and (5) secondarily grouting: spot-welding the anchor bolt and a screw cap of the equipment when the strength of primarily grouted concrete reaches over 75 percent, dismounting the temporary liner plates, making an equipment base die below the equipment base and grouting integrally.

Description

technical field [0001] The invention relates to an installation and construction method of a backing plate in the installation of large-scale precision equipment, and belongs to the technical field of equipment installation. Background technique [0002] The key procedure to control the installation accuracy of large and precision equipment is the installation of the backing plate, so the quality of the backing plate installation determines the quality of the equipment installation, the stability of the equipment operation and the quality level of the product, and the quality of the backing plate Installation also determines the economical requirements for equipment installation. [0003] At present, the placement methods of the equipment installation backing plate are mainly the basic grinding method and the slurry method. The basic grinding method generally uses a flat backing plate and a set of inclined backing plates to form a backing plate group, and the number of back...

Problems solved by technology

The basic grinding method generally uses a flat backing plate and a set of inclined backing plates to form a backing plate group, and the number of backing plates is large; the basic grinding method needs to perform basic grinding at the position of the equipment backing plate in advance to make it reach the contact surface and levelness. Requirements, and then place the backing plate, but it cannot be implemented when the position of the backing plate is uncertain, and at the same time, it cannot ensure good contact between the backing plate and the equipment. In many cases, the reserved space of the equipment is too large, and a second installation is required. The foundation grinding method needs to grind the foundation at each set of gaskets, not only to ensure the levelness of the backing plate, but also to ensure that the contact area between the backing plate and the foundation is more than 75%, which takes a lot of time and labor and material costs

The grouting method digs a grout pit at the position where the backing plate of the equipment is arranged, and then uses grouting material or high-strength concrete for the grouting. Although the amount of the backing plate is reduced, the backing plate is still needed to adjust the height. The problem of this method It is necessary to dig a slurry pit, which is likely to destroy the original foundation, which is not economical, requires tools and time, and cannot ensure good contact between the backing plate and the equipment

The processes of the two methods are relatively complicated. In view of the high quality requirements for WISCO project installation in recent years, the tight construction period, and the fact that some foreign equipment does not allow the construction of inclined pads, in order to solve the quality and Due to construction period requirements and cost savings, it is necessary to explore a new backing plate installation method
