Description
Technical field
The utility model relates to a kind of swelling device that is used for the sub-base grader traveling gear, belongs to road engineering machinery.
Background technology
As everyone knows; In road, railway, place construction and improvement project; Paving of base material is a very important job, and paver is adopted in the laying of base material usually, and existing paver traveling gear generally is made up of Hydraulic Pump, motor, planetary reduction gear etc.; Package unit adopts hydrostatic drive, and cost is higher.Cterpillar drive is strong to the landform comformability; Have advantages such as tractive force is big, grounding pressure is low, hill climbing ability is strong, turn radius is little; Therefore extensively be used as the traveling gear of big machinery; The chassis traveling gear of paver is made up of " four-wheel one band " (being drive wheel, track adjusting wheel, caterpillar wheel, support roller and crawler belt), swelling device and buffering spring, traveling gear, walker etc., and wherein the crawler belt swelling device has very big influence to the crawler travel performance.In the prior art, the main method of tensioner crawler belt comprises spring swelling method, oil cylinder tensioner method, screw rod tensioner method.Wherein the spring swelling method is owing to have certain proportionate relationship between the elastic force of spring and its scantling of structure; Spring undersized; Its elastic force is not enough to crawler belt is remained on the state of tensioner, spring oversize, and the restriction of the crawler belt physical construction that rises is difficult for installing and using; And adopt oil cylinder and screw rod tensioner method, and because the good rigidly of oil cylinder and screw rod is not yielding, when crawler belt received impulsive force, crawler belt can not keep it to be in the tensioner state at any time, the effect of its tensioner will be had a strong impact on.
Summary of the invention
The utility model technical matters to be solved is the deficiency that overcomes prior art, and a kind of tensioner shock absorber of rational in infrastructure, long service life is provided.
For solving this technical matters; The utility model provides a kind of paver traveling gear tensioner shock absorber; Comprise bearing, locking plate, pull bar, spring, O type circle, oil cylinder, axle, seal ring, support ring, dust seal, fuel feeding valve and annex; The upper end of said oil cylinder is provided with axle, and its bottom is connected with bearing through pull bar, and said axle is positioned at the outer end of oil cylinder and is provided with fuel feeding valve; Between the end of said oil cylinder and bearing spring is installed, said seal ring and support ring are arranged near mouthful of place of oil cylinder.
Said bearing makes the end that is fixed by bolts to pull bar through locking plate.
The junction of said pull bar and oil cylinder is provided with O type circle.
The place is provided with dust seal in cylinder ports.
Said fuel feeding valve is positioned on the sidewall of shaft end.
Beneficial effect: the utility model adopt preposition seal structure, and rational in infrastructure, good seal performance, life-span are long.

Said pull bar 3 is provided with O type circle 5 with the junction of oil cylinder 6, prevents that in-oil cylinder grease from oozing out.
The place is provided with dust seal 10 in oil cylinder 6 apertures.
Shown in Figure 2 is the structural representation left view of the utility model.
Said bearing 1 makes the end that is fixed by bolts to pull bar 3 through locking plate 2, the maximum moving range of restriction pull bar 3.
Shown in Figure 3 is that the A of the utility model is to scheme drawing.
Said fuel feeding valve 11 is positioned on the sidewall of axle 7 ends.
The utility model adopt preposition seal structure, and rational in infrastructure, good seal performance, life-span are long.
The above-mentioned embodiment of the utility model, just casehistory is not only, all in the utility model scope or the change that is equal in the scope of the utility model all surrounded by the utility model.
