BACKGROUND OF THE INVENTION

1. Field of the Invention

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.

2. Description of the Related Art

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.

However, the strength of these leveling feet cannot sufficiently resist the transverse force produced by an earthquake. The transverse force might shear the leveling feet to crash. 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. The types of the manufacturing equipment are versatile, fastening members and the means for positioning them in the manufacturing equipment rely on the type thereof. 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. Considering the protection of the manufacturing equipment, the wheels should be evenly positioned on frame of the equipment. Therefore, positioning the seismic-protection fastening kits at the locations for receiving the wheels complies with legal requirements. Moreover, the same seismic-protection fastening kits are suitable for manufacturing equipment with the same or similar types. Thus, the difficulty of developing different kinds of seismic-protection fastening elements for different types of manufacturing equipments is avoided.
