Specific embodiment
Below according to drawings and examples, the present invention is further described.
As depicted in figs. 1 and 2, a kind of from walking crane crawler belt regulating device, crawler unit or so respectively has a rubber
Glue crawler belt 1, driving wheel 7 are mounted in the front end of track frame 4, by hydraulic motor driven speed reducer 8, driving wheel 7 are driven to rotate,
And then rubber belt track 1 is driven to rotate, drive entire vehicle to move forward or back, then car body weight passes through track frame 4 in rotary course
It is distributed on two slat gum crawler belts 1, pressure is distributed on rubber belt track 1 by thrust wheel 5, rubber belt track 1 and ground face contact
Area is big, small to geostatic pressure, is not susceptible to collapse sedimentation.Guide wheel 2 is mounted in the tail portion of track frame 4, and the inside of guide wheel 2 exists
It is slided in sliding rail, the center between guide wheel 2 and driving wheel 7 is adjusted away from completion crawler tensioning by tensioning apparatus 3.Track frame 4
It is equipped with crawler rack 13 close to the side of guide wheel 2, tensioning apparatus 3 is fixed on crawler rack 13, tensioning apparatus 3 includes tensioning
The other end of oil cylinder 11, tensioning hydro-cylinder 11 is connect with the bracket of guide wheel 2, and tensioning hydro-cylinder 11 is equipped with and is passed through 11 nothing of tensioning hydro-cylinder
The hydraulic fluid port 12 of rod cavity, hydraulic fluid port 12 are equipped with check valve.The cylinder bottom and crawler rack 13 of the tensioning hydro-cylinder 11 are fixed, tensioning hydro-cylinder
11 piston rod is connect with the bracket of guide wheel 2.
When needing to dismantle or installing crawler belt, the check valve of hydraulic fluid port 12 is laid down, is discharged in 11 rodless cavity of tensioning hydro-cylinder
Grease, the piston rod of tensioning hydro-cylinder 11 are retracted into the cylinder body of tensioning hydro-cylinder 11, and guide wheel 2 retracts to minimum position, make to drive
Center makes rubber belt track 1 that can be packed into driving wheel 7, Zhi Chong in a relaxed state away from minimum is reduced between wheel 7 and guide wheel 2
In the track that wheel 5, guide wheel 2, tugboat 6 are formed.
When normal work needs to be tensioned, grease is injected by hydraulic fluid port 12 using grease gun, to the rodless cavity of tensioning hydro-cylinder 11
Interior injection grease, and then the piston rod of tensioning hydro-cylinder 11 is stretched out, drive guide wheel 2 protruding, and then make driving wheel 7 and draw
Center is away from incrementally increasing between guide wheel 2, the track for forming rubber belt track 1 in driving wheel 7, thrust wheel 5, guide wheel 2, tugboat 6
In be gradually tensioned.
As the improvement of the present embodiment, guide wheel slideway 9 is additionally provided on the track frame 4, the bracket of guide wheel 2 is located at
In guide wheel slideway 9, tensioning hydro-cylinder 11 is protruded into guide wheel slideway 9 and is connect with the bracket of guide wheel 2.So that tensioning hydro-cylinder 11 exists
The piston rod of guide wheel 2 and tensioning hydro-cylinder 11 is guided to be moved by guide wheel slideway 9 when flexible.
Further, the end of the piston rod of the tensioning hydro-cylinder 11 is fixedly connected with tensioning bracket 10, is tensioned bracket
10 are fixedly connected with the bracket of guide wheel 2.Further, the cylinder bottom of the tensioning hydro-cylinder 11 and crawler rack 13 are close to drawing
