Embodiment Construction

[0021] The present invention is further illustrated below by specific examples.

[0022] Such as Figure 1~Figure 4 As shown, a jacking construction method of a large shock-absorbing module; including

[0023] Step 1. Install the vibration isolator: set a group of vibration isolators (A2) every 1m~3m in the grooves on both sides of the vibration-absorbing module (A), and mark the vibration isolators (A2) on the surface of the concrete foundation box (A0). )Location;

[0024] Step 2. Acceptance of the contact surface: the horizontality of the contact surface between the shock isolator (A2) and the concrete foundation box (A0) and the shock absorption module (A) is not greater than 2mm / m, and the vertical space elevation error between the contact surfaces is not greater than ± 3mm, the distance between horizontal and vertical steel bars at the jacking point is 2 / 3 of that of other areas, and the steel bar size is 1-2 specifications larger;

[0025] Step 3. Installation of ant...

Abstract

The invention relates to the field of installation of large equipment, in particular to a jacking construction method of a large damping module. The method is characterized by comprising the steps of1, arranging vibration isolators; 2, checking and accepting a contact surface; 3, installing antiskid cushion plates; 4, installing the vibration isolators; 5, adjusting the installation of the cushion plates; 6, repeating the step 5 to sequentially adjust the installation of the cushion plates for the vibration isolators respectively, and carrying out same-direction simultaneous operation from the two sides of the damping module; 7, installing thick steel cushion plates; 8, repeating the step 7 till ten 10-mm steel cushion plates are installed on each vibration isolator (A2), and jacking thedamping module (A) to a working height; 9, fixing the 10-mm steel cushion plates above each vibration isolator (A2) through spot welding; and 10, releasing the vibration isolators. The construction method is simple, safe and reliable in installation process, free of special measures, economical and efficient, and solves the technical problem of jacking construction of large damping modules.

Description

technical field [0001] The invention relates to the field of installation of large equipment, in particular to a jacking construction method of a large shock absorbing module. Background technique [0002] With the development of modern industry, the precision manufacturing industry is also developing. When precision equipment is in production, if the vibration of the external environment is transmitted to the equipment body, it will seriously affect the product quality. The shock absorption module is the shock absorption basis of precision equipment, and its function is to work together with spring vibration isolators and dampers to provide shock absorption for precision mechanical equipment. With the development requirements of the precision manufacturing industry, the volume and weight of precision equipment are designed to become larger and larger, and the volume and weight of the corresponding shock absorption module also increase accordingly. The weight of the larges...
