Preferably, the damper is hydraulic damper.

Preferably, the sand is metal sand.

The utility model proposes a kind of bridge widening construction vibration absorber, beneficial effect is: by being arranged in hand Damper is set below handle, and installs spring leaf additional between damper, achievees the purpose that damping in work progress, while in handle Holding at the internal cavity equipped with sand of setting improve damping effect.

Detailed description of the invention

Fig. 1 be the utility model proposes a kind of bridge widening construction vibration absorber structural schematic diagram.

In figure: handle 1, pedestal 2, connecting rod 3, spring leaf 4, damper 5, contraction pole 6, connector sleeve 7, rotating hole 8, locking Screw 9, sand 10.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

Referring to Fig.1, a kind of bridge widening, which is constructed, uses vibration absorber, including pedestal 2, by being welded at the top of pedestal 2 Handle 1, handle 1 are T-shaped structure, convenient hand-held, and 1 handgrip part of handle is cavity structure, are equipped with sand 10, sand in cavity 10 be metal sand, and metal sand can carry out shock-absorbing when shaking and generating.

The bottom of pedestal 2 is rotatably connected to connecting rod 3 by shaft, and connecting rod 3 is two and is symmetrical arranged, connecting rod 3 One end far from pedestal 2 is fixed with damper 5, and damper 5 is hydraulic damper, and the side of damper 5 is rotated by shaft to be connected It is connected to contraction pole 6, the one end of two contraction poles 6 far from damper 5 is flexibly connected by connector sleeve 7, and spiral shell is equipped on the inside of connector sleeve 7 Line, one end of contraction pole 6 are equipped with screw thread corresponding with connector sleeve 7, are drilled with several rotating holes 8 on the outside of connector sleeve 7, need to adjust With being rotated in ripping bar insertion rotating hole 8 when saving the spacing of two contraction poles 6, the connector sleeve 7 by setting screw thread in driving reaches To tightening effect.

Spring leaf 4 is equipped between two dampers 5, the both ends of spring leaf 4 pass through shaft respectively and are rotatably connected on damper 5 Side, the bottom of damper 5 are equipped with perforative locking hole, and matched lock screw 9 is equipped in locking hole, use Shi Xuanzhuan connector sleeve 7 adjusts the spacing of two dampers 5 to suitable position, and lock screw 9 is locked on construction equipment (as cut Machine, broken original text), slow down construction equipment by damper 5 and the common shock-absorbing of spring leaf 4 and the vibration of operator is driven, together When cavity at the holding of handle 1 inside setting equipped with sand improve damping effect, increase the operability of constructing operation.

The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model Within enclosing.
