Abstract
The utility model discloses a torsion shock absorber for a compactor. The torsion shock absorber comprises a shock absorber casing, wherein a torsion bar shaft which can rotate corresponding to the casing is inserted in the trepan boring of the casing, an elastic damping element which can obstruct the torsion bar shaft to rotate corresponding to the casing is pressed between the torsion rod shaft and the wall of the trepan boring, and the casing and the torsion bar shaft are both provided with mounting connecting holes. The torsion shock absorber is provided with the elastic damping element between the torsion bar shaft and the casing, and has simple structure and convenient use. A rubber strip is adopted as the elastic damping element, which can save the production cost, and enhanced the shock absorption effect compared with an existing shock-absorbing block, avoids the phenomenon that a shock absorber is damaged during use, reduces the maintenance frequency of a compactor which uses the shock absorber, and increases the working efficiency of the compactor.
Description
Technical field
The utility model relates to a kind of damping device that uses with on the vibro-rammer machine of building or build the road.
Background technology
At present; in the building or the field of building the road, often need use dull and stereotyped rammer machine; dull and stereotyped rammer machine drives upper and lower the beating of rammer machine by centrifugal device at work; produce strong vibrations; for protecting the safety of the driving arrangement of installing on the rammer machine; avoid vibrations that equipment is caused damage, and alleviate the influence that vibrations are operated the operator, therefore on the dull and stereotyped rammer machine damping device is installed all.Cylindrical or the conical damping rubber block of the general employing of damping device on the existing rammer machine fixes installation as main shock absorbing means by the fixed axis that is installed in the snubber block.
In the existing dull and stereotyped rammer machine, damping rubber block generally is to be installed on the rammer machine by the fixed axis that level is installed between body support plate and the tamping plate, upper and lower impact force of beating generation forms the upper and lower shearing force to snubber block during the work of rammer machine, rupture in the middle of causing snubber block easily, influence the use of rammer machine; Afterwards, for reducing the damage of damping rubber block, the mounting means of damping rubber block is improved, the damping rubber block setting is vertical configuration or skewed being installed on the rammer machine, though this method has reduced the spoilage of snubber block, but its damping effect also decreases, and rams the vibrations that produce in the machine work and can not effectively be slowed down.
The utility model content
The purpose of this utility model is at above-mentioned defective, and a kind of rammer machine torsional mode damper is provided, characteristics such as that this damper has is simple in structure, durable in use, good damping effect.
The technical solution of the utility model is: a kind of rammer machine torsional mode damper, comprise the damper overcoat, be inserted with the torsion bar axle that can rotate relative to overcoat in the trepanning of this overcoat, be press-fitted between the cover hole wall of this torsion bar axle and overcoat and hinder the torsion bar axle, on described overcoat and torsion bar axle, also be respectively equipped with the installation connecting hole with respect to the elastic damping part that overcoat rotates.
Further improve, between described overcoat and torsion bar axle, also be provided with axial positioning structure.
Further, described axial positioning structure comprise that the cover bore edges that is positioned at overcoat one side end face radially is provided with towards the convex annular edge in axle center, at the opposite side end face of overcoat near being provided with end cap.
Further, described axial positioning structure comprises on the end face of overcoat one side near the end cap that is provided with, on overcoat opposite side end face, be positioned at the trepanning edge and offer annular groove, radially be provided with the convex annular edge corresponding with this annular groove in an end end of described torsion bar axle; The other end end face center of torsion bar axle offers groove, and described end cap thrust is assemblied in this groove.
Further, the outer rim end face of described closed end cap is provided with the convex annular edge of diameter greater than the overcoat trepanning, and described overcoat end face is provided with annular groove that should the convex annular edge.
Further, described installation connecting hole is bolt hole or the screwed hole that is provided with vertically.
It is foursquare square structure that described torsion bar axle and overcoat trepanning are the cross section, the tetragonal triangularity cavity of torsion bar axle and overcoat trepanning, and described elastic colloid is leg-of-mutton rubber shock-absorbing bar for the cross section identical with this cavity body structure.
The utility model adopts the torsional mode damping, fills out between torsion bar axle and overcoat and establishes the elastic damping part, and it is simple in structure, and is easy to use; Axial positioning structure can prevent that phenomena of the failure such as axle sleeve separates, damping piece drops from use appearring in damper; When in the rammer machine, using, change former shearing force on the damping rubber block or the axial compression power of acting on into radially extruding force, existing relatively snubber block has been strengthened damping effect, and long service life, reduce the repair rate of the rammer machine that uses this damper, increased the work and the service efficiency of the machine that rams.
