Method for levelling and mounting base of mechanical equipment

Abstract

The invention provides a method for levelling and mounting a base of mechanical equipment. The method comprises the following steps of: on two sides of each foundation bolt, connecting sizing blocks with concrete foundations by using more than three bolts; levelling all the sizing blocks to make the levelness of each sizing block within 0.5mm / 1,000mm and the levelness among all the sizing blocks within 1mm / 1,000mm; carrying out injection molding around each sizing block by using a fluid spouting material to form a plurality of first casting bodies which expose upper surfaces of the corresponding sizing blocks and surround and support the corresponding sizing blocks; placing a main base plate on the sizing blocks; carrying out secondary casting around the main base plate by using the fluidspouting material to form a second casting body which exposes the upper surface of the main base plate and surrounds and supports the main base plate; fixing the base of the mechanical equipment placed on the second casting body with the concrete foundations by using a plurality of foundation bolts. The method can be used for levelling and mounting the mechanical equipment such as an autogenous mill, a ball mill, a draught fan, a combustion gas turbine, a turbine and the like.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment installation, more specifically, to a method for leveling and installing a mechanical equipment base. Background technique [0002] Typically, most mechanical equipment has issues leveling (also known as leveling) its base during installation. Especially when installing large mechanical equipment, it is more important to level its base. If the base of the mechanical equipment is not leveled during installation, large deviations will occur when the mechanical equipment is running (for example, rotating or vibrating, etc.), and in severe cases, it may even lead to production accidents or casualties. . The mechanical equipment mentioned here includes autogenous mills, ball mills, fans, gas turbines, turbines, etc. [0003] The following will take large autogenous mills as an example to describe the deficiencies in the prior art. Generally, large-scale autogenous mills (also called la...

Problems solved by technology

[0006] In view of the above problems, the present invention uses thread self-adjustment combined with a precision level to level and install the base of the mechanical equipment, which solves the problems of "slurry collection" and "slurry leakage" that exist during the installation of mechanical equipment (especially large-scale mechanical equipment). ", foundation cracking and other reasons can not meet the high precision level requirements
