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.

1 . A seismic-protection wheel locational anchorage, comprising: 
 a first fastening member including a first horizontal part and a first perpendicular part vertically and downwardly extending from one end of said first horizontal part, said first horizontal part having at least one first elongated hole and said first perpendicular part having at least one second elongated hole, said first horizontal part fastened to the bottom of a machine frame by a fastening means passing through one locating hole formed on the bottom of said machine frame and said first elongated hole of said first horizontal part;    a second fastening member including a second perpendicular part and a second horizontal part extending parallel from a lower end of said second perpendicular part, said second horizontal part having at least a third elongated hole and said second perpendicular part having at least a fourth elongated hole, said second horizontal part secured to a ground by a fastening means passing through said third elongated hole of said horizontal part and the ground;    wherein when the vertical level could be appropriately adjusted to fit the gap between the machine frame and the ground, said first fastening member and said second fastening member are securely joined together by at least one fastening means passing through said second elongated hole of said first fastening member and said fourth elongated hole of said second fastening member.    
   
   
       2 . The seismic-protection wheel locational anchorage as claimed in  claim 1 , wherein said first elongated hole is formed on said first horizontal part of said first fastening member in a longitudinal direction and said third elongated hole is formed on said second horizontal part of said second fastening member in a longitudinal direction.  
   
   
       3 . The seismic-protection wheel locational anchorage as claimed in  claim 1 , wherein said second elongated hole is respectively formed on two opposite sides of said first perpendicular part of said first fastening member in a longitudinal direction and said fourth elongated hole is respectively formed on two opposite sides of said second perpendicular part of said second fastening member in a longitudinal direction.  
   
   
       4 . The seismic-protection wheel locational anchorage as claimed in  claim 3 , wherein said first fastening member and said second fastening member are securely joined together by a check bolt with a spring washer passing through said second elongated hole and said fourth elongated hole.  
   
   
       5 . The seismic-protection wheel locational anchorage as claimed in  claim 1 , wherein said first fastening member is further provided with at least one first inclined elongated hole between the two opposite sides thereof and said second fastening member is further provided with at least one second inclined elongated hole between the two opposite sides thereof.  
   
   
       6 . The seismic-protection wheel locational anchorage as claimed in  claim 5 , wherein said first inclined elongated hole and said second inclined elongated hole are positioned in a relationship of crossing each other.  
   
   
       7 . The seismic-protection wheel locational anchorage as claimed in  claim 6 , wherein said first inclined elongated hole and said second inclined elongated hole cross each other to form a single hole penetrating them, and said first fastening member and said second fastening member are more securely joined together by a fastening means passing through the single hole.
