Abstract
The invention relates to the field of bridges, more specifically to a railway bridge base stable positioning device. The railway bridge base stable positioning device comprises a base, a cross column,an L-shaped connecting rod, a top plate, leg rods, a bottom plate, V-shaped load-bearing pieces and breaking grooves. According to the railway bridge base stable positioning device, two V-shaped load-bearing pieces are arranged to bear the load so as to guarantee the stability of the bridge; when stress on a bridge base is too large, the two V-shaped load-bearing pieces may be broken, and at themoment, a buffering structure buffers the force to prevent the bridge from being damaged. The base is arranged on the upper side of the bottom plate; the L-shaped connecting rod is fixedly connected to one side of the base; the middle part of the cross column is fixedly connected to the upper end of the L-shaped connecting rod; the two leg rods are fixedly connected to the right end of the lower side of the top plate; the two leg rods are both slidingly connected to the cross column; the two V-shaped load-bearing pieces are fixedly connected to the bottom plate; the two V-shaped load-bearing pieces are both in V shapes; openings of the two V-shaped load-bearing pieces are oppositely formed; the breaking grooves are formed in the middle parts of the internal sides of the two V-shaped load-bearing pieces; and the lower ends of the two leg rods are correspondingly placed at the upper ends of the two V-shaped load-bearing pieces.
Description
