Definitions

  • the invention relates to a hand tamping machine for compacting track ballast.
  • a hand tamping machine for compacting track ballast is known from WO 2012/139 687 A1 .
  • the hand tamping machine includes a tamping pick for penetrating the track ballast, a vibration generator, an internal combustion engine for rotating the vibration generator and handles for guiding the hand tamping machine during operation.
  • Vibration dampers act between the vibration generator and the handles.
  • the vibrations transmitted to the handles cannot be completely eliminated and are stressful for the user. Noise and exhaust emissions generated by the internal combustion engine place additional strain on the user.
  • the invention is based on the object of improving a hand-held tamping machine for compacting track ballast, in particular to increase its ease of use and to reduce the stress it places on the user.
  • a hand tamping machine has a particularly high level of operating comfort when along a shaft axis of a drive shaft, which connects the motor with the Vibration generator connects, at least one handle for guiding the hand tamping machine is arranged by at least 30% of the height of the hand tamping machine above the machine's center of gravity of the hand tamping machine and / or is arranged by at least 15% of the height of the hand tamping machine above the center of gravity of the motor.
  • the arrangement of the at least one handle above the engine's center of gravity means that the user's head can be kept particularly far away from the engine that generates noise and / or pollutants. Due to its low-lying arrangement, the motor comes closer to the vibration generator. Surprisingly, however, it was found that the engine is not necessarily exposed to higher vibration loads as a result. Rather, by arranging it closer to the machine's center of gravity, a higher inertial damping can be achieved, which means that the vibrations transmitted to the motor can even be reduced.
  • the lower center of gravity of the machine in relation to at least one handle makes it easier to control the hand tamping machine.
  • the hand-held tamping machine that penetrates the track ballast is pivoted about a horizontal axis.
  • a corresponding pivoting movement of the hand tamping machine from the vertical orientation is supported by a high center of gravity of the machine.
  • the mass to be moved by the user and thus the total energy to be applied by the user, can be reduced due to the lower machine center of gravity, which means that the user tires less quickly.
  • the longer lever arm offers better control over the hand tamping machine compared to the machine's center of gravity.
  • a particular advantage of the hand tamping machine according to the invention is that the vibrations present on the at least one handle during operation and the associated stress on the user are particularly low. Due to the particularly low arrangement of the machine's center of gravity compared to the at least one handle, a vibration node of a rigid body vibration excited by the vibration generator can be relocated particularly close to the at least one handle. The resulting vibration amplitude on the at least one handle is therefore particularly low. Circulatory disorders and muscle diseases associated with continuous vibration stress can thus be prevented.
  • the tamping pick points vertically downwards.
  • Distances in relation to the at least one handle are, unless otherwise specified, to the top of the handle.
  • the shaft axis is preferably arranged coaxially to the central longitudinal axis and/or to the vertical axis of the hand tamping machine.
  • the machine center of gravity is understood to mean the center of gravity of the hand tamping machine, particularly when the hand tamping machine is in a ready-to-use state.
  • a fuel tank of the engine is half full and a preferably replaceable ballast contact attachment is attached to the hand tamping machine.
  • Guiding the hand tamping machine during operation means holding and moving the hand tamping machine when compacting the track ballast and/or carrying the hand tamping machine to the position of the track ballast to be processed.
  • the handle device preferably has at least two, in particular exactly two or at least three, in particular at least four, of the handles.
  • the position information provided in connection with the at least one handle preferably applies to all of the handles.
  • the at least one handle can be formed by and/or attached to a support structure.
  • the respective handle comprises a vibration-damping material, in particular a plastic and/or a rubber-elastic material.
  • a power adjustment element, in particular a throttle lever, for regulating the power delivered by the engine can be arranged on the at least one handle, in particular in such a way that the user does not have to release his hand from the handle in order to operate the power adjustment element.
  • the vibration generator is arranged at least in sections in a tamping pick tube. This allows the hand tamping machine to compact the track ballast in a particularly time- and energy-efficient manner.
  • the vibration generator can have an unbalanced mass arranged eccentrically to the shaft axis, in particular completely within the tamping pick, in particular within a tamping pick tube. As a result, the vibration excitation can take place particularly close to the track ballast, whereby the kinetic energy used can be transferred to the track ballast largely without loss.
  • the vibration excitation of the at least one handle and the motor is, however, reduced.
  • the tamping pick preferably comprises an attachment support and a gravel contact attachment that can be detachably attached to the attachment support.
  • the ballast contact attachment which is exposed to high stress due to contact with the track ballast, can therefore be easily replaced.
  • the tamping pick in particular the attachment support, is preferably hollow, in particular tubular.
  • the attachment support can be designed as a tamping pick tube.
  • the vibration generator is arranged at least in sections within the tamping pick tube or tubular tamping pick.
  • An unbalanced mass of the vibration generator can be arranged completely within the tamping pick tube and/or can be completely overlapped by the tamping pick tube along a direction perpendicular to the shaft axis.
  • the vibration generator is preferably designed in such a way that the forces generated to stimulate the tamping pick to vibrate act perpendicular to the shaft axis, in particular in the horizontal direction.
  • the transmission of vibrations oriented perpendicular to the shaft axis to the at least one handle and/or the motor is particularly strongly inhibited in the hand tamping machine according to the invention.
  • the hand tamping machine preferably comprises the at least one handle, the motor center of gravity, the machine center of gravity and a tip of the tamping pick.
  • a vibration node can thereby be arranged particularly close to the at least one handle along the shaft axis.
  • the overall height of the hand tamping machine and/or the distance between the at least one handle and the underside of the Tamping picks in a range from 850 mm to 1250 mm, in particular from 950 mm to 1150 mm, in particular from 1000 mm to 1100 mm.
  • a hand tamping machine is particularly user-friendly.
  • the vibration movements transmitted to at least one handle are reduced even further.
  • the hand tamping machine is even easier to operate.

This makes it possible to achieve a particularly high level of operating comfort.
  • a hand tamping machine is particularly user-friendly. By arranging the engine's center of gravity far away from the at least one handle, the user is less exposed to noise and/or exhaust emissions. Vibrations emanating from the motor are transmitted less strongly to the at least one handle due to the greater proximity to the machine's center of gravity and the resulting greater inertial damping.
  • the motor center of gravity is preferably arranged along the shaft axis in a range from 15% to 50%, in particular from 20% to 40%, in particular from 25% to 30%, of the height of the hand tamping machine below the at least one, in particular all, handles.

  • the burden on the user caused by vibrations transmitted to the at least one handle is particularly low.

  • this connection point is arranged opposite the tamping pick in relation to the center of mass, whereby vibrations on the at least one handle are particularly comprehensively reduced by the particularly strong inertial damping in the area of the machine's center of gravity. The damping effect is increased and the vibration load on the user is reduced.
  • a hand tamping machine ensures a particularly high level of operating comfort.
  • the motor center of gravity and the handle-side connection point of the first vibration decoupler are preferably arranged along the shaft axis between the at least one handle and the machine center of gravity. This reduces the vibrations transmitted to the motor and/or the handle device.
