Damping spring vibration isolator device with expansion sleeve and its installation and adjustment method

Abstract

The invention discloses a damping spring vibration isolator device with expansion sleeves. The device comprises an upper bearing plate component, wherein the upper bearing plate component and a lower bearing plate component are connected with an upper sleeve and a lower sleeve for mounting a damper component; the upper and lower ends of the damper component are connected into the upper sleeve and the lower sleeve through the expansion sleeves respectively; the bottom of the lower bearing plate component is connected with a height adjusting component. A mounting and adjusting construction method of the damping spring vibration isolator device with the expansion sleeves comprises the following steps: assembling the damping spring vibration isolator device with the expansion sleeves; arranging the damping spring vibration isolator device with the expansion sleeves at an equipment foundation; adjusting height, releasing pre-compression of the spring and adjusting the height again. The damping spring vibration isolator device with the expansion sleeves can be locked after the upper and lower bearing plate components and the spring are assembled and the pre-compression is applied, and is convenient to assemble and reliable to connect; the length of the damper and the height of the vibration isolator are rational; the damping spring vibration isolator device with the expansion sleeves is adjustable in height; the mounting and adjusting construction method is simple and convenient; the precision is guaranteed; the construction efficiency is favorably improved; the construction period is shortened.

Description

technical field [0001] The invention relates to the technical field of vibration reduction and isolation, in particular to a damping spring vibration isolator device with an expansion sleeve and an installation and adjustment method thereof. Background technique [0002] The damping spring vibration isolator is mainly assembled in parallel by spring and damper components, and a certain preload is applied. The size of the preload is calculated according to the design and calculation of the self-weight of the vibration isolation system of the power equipment. The damping spring vibration isolator is fully considered during engineering use and installation. The number of dampers in the damping system and the layout requirements require the vibration isolator itself to be compact and easy to use and install. Therefore, most damping spring vibration isolators install the damper at the central position of multiple sets of parallel springs (such as attached Figure 8 , 9 shown). ...

AI Technical Summary

Problems solved by technology

[0004] 1. The installation of the damper is inconvenient. If the damper is tightened and fixed after the preload is applied to the spring, due to space constraints, it is difficult to operate the installation tool;

[0005]2. If the damper is installed first, then the spring is installed, and after the spring is placed in the correct position, the preload is applied and then locked. This method needs to design the movable stroke of the damper to be longer, and the problem brought about is the vibration isolator. The height and the length of the damper will increase accordingly, the cost will increase, and there will be a hidden danger of instability during installation;

[0006]3. When applied to the vibration isolation of power equipment, it is often encountered during installation that the heights of the vibration isolators arranged side by side are not on the same level, the heights are inconsistent, and there is a large height difference. However, the height of the existing damping spring vibration isolators cannot be adjusted arbitrarily. The method is often to meet the installation quality requirements by continuously placing steel plates of a certain thickness on the upper surface of the vibration isolator. Since the required thickness of the steel plates is often different, the on-site leveling is not only cumbersome but also has unsatisfactory accuracy.
