For solving the problems of the technologies described above, the technical scheme that the present invention proposes is:
A kind of adjustable bridge pad pinner, comprise bottom deck assembly, height adjustment assembly and the back-up block for supporting bridge bearing, described height adjustment assembly comprises wedge block and regulating part, described wedge block is connected on bottom deck assembly by regulating part and also can moves horizontally under the adjustment of regulating part, on the lozenges that described back-up block is positioned over wedge block and can moving horizontally and move up and down with wedge block, described bottom deck assembly is provided with wedge block limiting plate, and the surrounding of back-up block is also provided with locating part.
Further improvement as to technique scheme:
Described regulating part comprises the adjusting screw(rod) and nut that cooperatively interact, described wedge block inside is provided with cavity, do not rotate in the cavity that nut is fixed on wedge block, the end of thread of adjusting screw(rod) is connected with nut, and the adjustable side of adjusting screw(rod) passes the side of described bottom deck assembly.
Described bottom deck assembly is box structure, its side and top are provided with opening, described wedge block is positioned over box structure inside from side mouth, described adjusting screw(rod) is connected on the side plate relative with open side, described back-up block is positioned over wedge block from top open part, and the steel plate of box structure top surrounding forms described locating part.
Described wedge block limiting plate is arranged at the side mouth place of box structure.
Compared with prior art, the invention has the advantages that:
Bridge pad pinner of the present invention is an a kind of seat mounting apparatus newly, innovates bearing replacement and leveling construction method.Its frame mode adopting wedge block to combine with screw mechanism, realize the conversion of rotary motion and rectilinear motion, convert the rotation of adjusting screw(rod) to wedge block moving horizontally, and convert the difference in height of each for wedge block section to back-up block moving up and down by the back-up block above it, when not jacking bridge, can be quick, carry out support leveling and replacing safely, and do not affect the normal use of bearing, construction equipment is simple, height regulating mechanism is easy and simple to handle, internal activity part not only can be gone slick, and its position energy positive lock, firm in structure durable, have that labour intensity is little, efficiency is high, can substantial contribution be saved, and reduce the advantage of the potential safety hazards such as hinge seam cracking, local concrete destruction that bridge produces because of jacking.
