Seismic-protection wheel locational anchorage

Abstract

A seismic-protection wheel locational anchorage is provided. The present seismic-protection wheel locational anchorage includes a first fastening member and a second fastening member. The first fastening member has a first horizontal part and a first perpendicular part vertically and downwardly extending from one end of the first horizontal part. The second fastening member has a second perpendicular part and a second horizontal part extending parallel from a lower end of the second perpendicular part. The first horizontal part of the first fastening member is fastened to the bottom of a machine frame. The second horizontal part is securely fastened to the ground. When the vertical level between the machine frame and the ground is appropriately adjusted, the first perpendicular part and the second perpendicular part are securely joined together so as to provide the seismic-protection wheel locational anchorage for the machine frame.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a seismic-protection fastening means, and more particularly to a seismic-protection wheel locational anchorage, by which a machine can be securely fastened to the ground. [0003] 2. Description of the Related Art [0004] Taiwan is located in a fault-concentrated zone, about two hundred felt earthquakes occur in Taiwan every year. Thus, seismic-protection for manufacturing equipment is required as most components are very precise in essentiality and in function. In addition to seismic-protection fastening elements provided in the manufacturing equipment, for convenient operation and easy installation, brackets on leveling feet are provided for the most manufacturing equipments to serve as fastening elements. These seismic-protection elements are positioned at the feet of the stand. [0005] However, the strength of these leveling feet cannot sufficiently resist the transverse force produc...

AI Technical Summary

Benefits of technology

[0007] The objective of the present invention is to provide a seismic-protection wheel locational anchorage including a first fastening member and a second fastening member capable of separately joining together. The first fastening member is fastened to a bottom of a machine frame by a fastening means passing through an elongated hole on the first fastening member and one locating hole on the machine frame originally had for a wheel, and the second fastening member is securely fastened to the ground by another fastening means. The joint location between the first fastening member and the second fastening member is adjustable so as to fit the vertical gap between the machine and the ground. The machine can be firmly fastened to the ground by the present seismic-protection wheel locational anchorage. Extra work to drill additional holes on the machine frame used for fastening is avoided.

[0011] The first fastening member and the second fastening member can be joined together by a check bolt with a spring washer passing through the second elongated hole and the fourth elongated hole. The joining between the first fastening member and the second fastening member is thus reinforced.

Problems solved by technology

However, the strength of these leveling feet cannot sufficiently resist the transverse force produced by an earthquake.

Although it is convenient to position the seismic-protection fastening brackets at the leveling feet, the insufficient strength of the leveling feet and the association between the seismic-protection fastening brackets and the leveling feet would result in a failure for positioning the seismic-protection fastening elements at the leveling feet.

Moreover, if the manufacturing equipment is not provided with receiving places for the seismic-protection fastening kits when manufactured, it will be necessary to drill holes on the manufacturing equipment for positioning the seismic-protection fastening elements.

As a consequence, the working cost is increased.

If the manufacturing equipment is larger and heavier, it is necessary to install several wheels on when the manufacturing equipment is to be transported.
