Description of drawings
Fig. 1 is the utility model assembly scheme drawing;
Fig. 2 is that the utility model installs energy storage assembly scheme drawing additional;
Fig. 3 is the utility model hydraulic schematic diagram;
Among the figure, 1 tension wheel; 2 track frames; 3 tension wheel erecting frames; 4 crawler belts; 5 tensioning hydro-cylinders; 6 energy storages; 7 check valves; 8 walking CD-ROM drive motor.
The specific embodiment
As Figure 1-3, the instant tightening device of the utility model development machine mainly is made up of tension wheel 1, track frame 2, tension wheel erecting frame 3, crawler belt 4, tensioning hydro-cylinder 5, energy storage 6, check valve 7, walking CD-ROM drive motor 8, wherein: track frame 2 inside are provided with tensioning hydro-cylinder 5 and tension wheel erecting frame 3, slideway in tension wheel erecting frame 3 and the track frame 2 cooperates, move in the slideway in track frame 2, each piece volumes should satisfy the track frame inner space.Tension wheel 1 is positioned at the outside of tension wheel erecting frame 3, and crawler belt 4 is installed on the tension wheel 1, and tension wheel erecting frame 3 cooperates the tensioning that realizes crawler belt 4 with tension wheel 1.One end of tensioning hydro-cylinder 5 connects tension wheel erecting frame 3, and the other end of tensioning hydro-cylinder 5 connects walking CD-ROM drive motor 8 by pipeline, on the pipeline between tensioning hydro-cylinder 5 and the walking CD-ROM drive motor 8 energy storage 6, check valve 7 is set.
When the running part of development machine moved, walking CD-ROM drive motor 8 oil inlets were introduced high pressure oil and are acted on tensioning hydro-cylinder 5, and tensioning hydro-cylinder 5 ejects tension wheel erecting frame 3, and tension wheel erecting frame 3 outwards moves on track frame 2 in-to-in slideways, realizes tensioned tracks 4; When running part quit work, tensioning hydro-cylinder 5 and walking were provided with check valve 7 between the CD-ROM drive motor 8, and the operation pressure of tensioning hydro-cylinder 5 when keeping development machine to stop to walk makes tensioning hydro-cylinder 5 in tension and not being contracted all the time; When development machine is worked under abominable operating mode; need before track frame 2 in-to-in tensioning hydro-cylinders 5, to install energy storage 6 additional; be used to absorb the hydraulic efficiency impact that causes when machine is worked under the bad working environments condition, absorb hydraulic pressure surge protection tightening device, and the leakage in additional tensioning loop.
