Abstract
A working device, especially a ramming device for compacting soil, comprises a housing which belongs to an upper mass, and has a working mass which can be linearly driven back and forth with regard to the upper mass. The working mass is linearly guided via a guide cylinder which is fastened to the housing with elastic mobility. The transfer of bounce impacts acting upon the working mass to the upper mass can be effectively reduced by the elastic mobility of the guide cylinder with regard to the housing.
Claims15
An implement, in particular a rammer for soil compaction or hammer, comprising:
- an upper mass, which has a drive arranged in or on a housing;
- a working mass, which can be driven to and fro linearly by the drive via a motion conversion device and a spring set;
- and
- a guide device, which is fixed to the housing and which has a guide cylinder which guides the working mass linearly relative to the housing;
- wherein the guide cylinder is fixed to the housing so as to be elastically movable relative thereto.
An implement, in particular a rammer for soil compaction or hammer, comprising:
- an upper mass, which has a drive arranged in or on a housing;
- a working mass, which can be driven to and fro linearly by the drive via a motion conversion device and a spring set;
- and
- a guide device, which is fixed to the housing and which has a guide cylinder which guides the working mass linearly relative to the housing;
- wherein the guide cylinder is fixed to the housing with elastic mobility, or the guide cylinder itself, given an otherwise rigid connection, has elastic mobility, and wherein at least one elastic element is inserted between the housing and the guide cylinder.
An implement, in particular a rammer for soil compaction or hammer, comprising:
- an upper mass, which has a drive arranged in or on a housing;
- a working mass, which can be driven to and fro linearly by the drive via a motion conversion device and a spring set;
- and
- a guide device, which is fixed to the housing and which has a guide cylinder which guides the working mass linearly relative to the housing;
- wherein the guide cylinder is fixed to the housing with elastic mobility, or the guide cylinder itself, given an otherwise rigid connection, has elastic mobility, wherein the guide cylinder has a fixing device which fixes the guide cylinder to the housing, wherein the guide cylinder has a fixing surface which extends essentially parallel to a stop surface provided on the housing and behind which the fixing device engages;
- and wherein the fixing surface has elastic properties.
An implement, in particular a rammer for soil compaction or hammer, comprising:
- an upper mass which has a drive arranged in or on a housing;
- a working mass which can be driven to and fro linearly by the drive via a motion conversion device and a spring set;
- and
- a guide device which is fixed to the housing and which has a guide cylinder which guides the working mass linearly relative to the housing;
- wherein the guide cylinder is rigidly connected to the housing and consists of a polymer such that it is elastically movable relative to the housing.
