Description
Affiliated technical field
The utility model belongs to the Work machine technology, and what relate generally to is the shock-damping structure of the portable tamping tool of a kind of impact type.
Background technology
At present, the mechanical type that is used for the railway bed upkeep operation now is a lot, and the machinery that is used for the roadbed tamping operation mostly is the vibration-type structure greatly.As hand held, electric pick, shock club etc., they are by internal-combustion engine drives, produce vibrations by vibrating mechanisms such as eccentric vibration blocks, because its operation belongs to vibration-type and makes firm by ramming, and do not have impact function, and by manpower shock club or pick are inserted shake behind the roadbed during operation and make firm by ramming, can only be used for the roadbed operation of loosening, and the many comparatively plates of railway bed are hard, and simple vibration-type Work machine can't reach the construction effect of expection.Adopt large-scale Work machines such as hydraulic power supply, need external power source, equipment is comparatively heavy, and because the particularity of the normal driving of the railway system, make the railway bed maintenance to carry out between train number, be the batch (-type) operation, this kind equipment can't adapt to this needs at all; In addition, often need broken road surface when railway bed is safeguarded construction, this also makes existing vibration-type Work machine can't adapt to its needs.
The inventor proposes the portable tamping tool of impact type thus, it is mainly smash by internal combustion engine, clutch, gear reduction, crank-link mechanism and displacer, impact piston and instrument shake and constitutes, the power of internal combustion engine drives crank connecting link and moves after the gear reduction speed change, crank-link mechanism drives displacer and makes impact piston drive shake smashes the reciprocating type impact in front and back of instrument do; Clutch, gear reduction, crank-link mechanism and displacer, impact piston all are arranged in the transmission case, and the transmission case outside has hood, and operator is being connected on the hood.This project separate case is applied for a patent.The portable tamping tool of this impact type is when having impact function, the problem that is produced be shake bigger, this brings very big difficulty must for the operator when operation, operation control is comparatively required great effort even can't be operated at all, and this certainly will will have influence on operating efficiency and operation quality.
Summary of the invention
The purpose that the utility model proposes the shock-damping structure of the portable tamping tool of impact type just is by its structure design, the vertical tremor that impact is produced is absorbed significantly, decomposes, reduce the brisance that is delivered to the operator handle to greatest extent, thereby guarantee the operating efficiency and the quality of tamping tool.
The utility model is finished the technical scheme that its invention task takes: be connected by four-bar mechanism between the hood of the portable tamping tool of impact type and the transmission case body, promptly be provided with a connecting rod and end and the transmission case body of connecting rod is hinged, the other end of connecting rod is connected on the hood.
One end of connecting rod is hinged by dampening assembly and transmission case body, and dampening assembly is made of the damping inner core and the connecting bolt that are fitted in shock-absorbing sleeve in the transmission case body installing hole, join with shock-absorbing sleeve inner wall shape kiss and are fitted in the shock-absorbing sleeve; Wherein, shock-absorbing sleeve is the outer wall of rigid material and the complex structure that the elastomeric material inwall constitutes; The damping inner core has center screw, has two or more outside arc convex on its outer wall, and an end and the damping inner core of connecting rod connect and compose linkage structure, and an end of connecting rod combines with the hood suit.
Tamping tool is produced vertical tremor by impact when operation, shock-absorbing sleeve and transmission case together shake, when shock-absorbing sleeve passes to the damping inner core with brisance, inner core makes the distortion of shock-absorbing sleeve elastic compression, by the elastic deformation between two gentle elastic components, vibration energy is absorbed, simultaneously, the arc convex of damping inner core will push shock-absorbing sleeve and angle of relative shock-absorbing sleeve twisting, drivening rod one end is done corresponding twisting, the relative hood swing of the other end of connecting rod will be delivered to the brisance digest and decompose of hood by transmission case.
The both sides of transmission case body have two symmetrically arranged arc wing plates up and down respectively, with the left and right sides hood inwall of its correspondence position on have the snubber block of flexible material, hood is connected flexible snubber block on the hood of back between two arc wing plates of transmission case body with transmission case body.During tamping tool work, transmission case body produces play up and down, and the last lower wing plate on the transmission case body all pushes the flexible snubber block on the housing up or down, makes it to be extruded and shrinkage strain, makes the brisance on the transmission case be absorbed digestion.
The shock-damping structure of the portable tamping tool of impact type that the utility model proposes, be absorbed significantly, decompose by impacting the vertical tremor that produces in the time of can making mechanical work, reduce to greatest extent and be delivered to hood, operator last brisance, guarantee mechanical operating performance, and guaranteed the operating efficiency and the quality of tamping tool thus.
