Abstract
The utility model provides a fixed pulley set assembling structure of a dynamic compactor. The fixed pulley set assembling structure comprises a pressing rod, two pull rods, a fixed pulley set and a fixed shaft. The two pull rods are arranged in parallel, the upper portion of the pressing rod is fixedly connected with the upper portions of the two pull rods, a plurality of pulleys are arranged in the fixed pulley set, the two ends of the fixed shaft are fixed to the upper ends of the two pull rods respectively, and the fixed pulley set is installed on the fixed shaft. Due to the fact that the fixed pulley set is installed on the fixed shaft, when rolling and unrolling of an amplitude-variable steel wire rope are adjusted, the fixed pulley set bears the joint application force of the amplitude-variable steel wire rope, the pull rods and the pressing rod, the position of the fixed pulley set cannot change greatly and interference with an adjacent mechanism cannot occur either. The fixed pulley set assembling structure of the dynamic compactor has the advantages of being simple in structure, safe to use and capable of prolonging the service life of the fixed pulley set and the service life of the pressing rod.
Description
Technical field
The utility model relates to a kind of dynamic compaction machinery fixed pulley assembling distribution structure.
Background technology
As shown in Figure 1, at present, the mounting structure of dynamic compaction machinery fixed pulley group 4a comprises two depression bar 1a, two pull bar 2a, fixed pulley group 4a, support 7a and anchor shaft 3a, two parallel placements of pull bar 2a, two same parallel placements of depression bar 1a, and the distance between two depression bar 1a is greater than two distances between pull bar 2a, two depression bar 1a upper ends and two pull bar 2a upper ends are fixed by anchor shaft 3a, hinged between support 7a and anchor shaft 3a, fixed pulley group 4a is arranged on support 7a, be wound with variable-amplitude steel wire rope 6a between running block 5a on fixed pulley group 4a and dynamic compaction machinery coxopodite arm, the end of variable-amplitude steel wire rope 6a is fixed on fixed pulley group 4a, the other end is fixed on span winch, while not using, span winch discharges variable-amplitude steel wire rope 6a, the application force that variable-amplitude steel wire rope 6a applies fixed pulley group 4a is little, support 7a is fitted on depression bar 1a because of Action of Gravity Field, when span winch shrinks variable-amplitude steel wire rope 6a, the application force that variable-amplitude steel wire rope 6a applies fixed pulley group 4a and running block 5a increases, drive support 7a away from depression bar 1a, the impact that support 7a and fixed pulley thereof are fallen suddenly by hammer ram when strong rammer is worked, the layback of coxopodite arm, distance between fixed pulley group 4a and running block 5a is diminished, cause that luffing fixed pulley group 4a impacts Shears, variable-amplitude steel wire rope 6a easily falls groove, accelerate variable-amplitude steel wire rope 6a and fixed pulley group 4a wearing and tearing, have potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of simple in structure, use safe dynamic compaction machinery fixed pulley assembling distribution structure.
For solving the problems of the technologies described above, the utility model provides a kind of dynamic compaction machinery fixed pulley assembling distribution structure, comprise depression bar, two pull bars, fixed pulley group and anchor shafts, two parallel placements of pull bar, depression bar top and two pull bars are fixed, several pulleys are arranged in the fixed pulley group, and described anchor shaft two ends are separately fixed at the upper end of two pull bars, and the fixed pulley group is arranged on anchor shaft.
After adopting such structure, the fixed pulley group is arranged on anchor shaft, and when regulating the folding and unfolding of variable-amplitude steel wire rope, the fixed pulley group is subject to the combined action power of variable-amplitude steel wire rope, pull bar and depression bar, huge change can not occur in the position of fixed pulley group, can not interfere with adjacent mechanism yet.
The beneficial effects of the utility model are: simple in structure, use safety, the service life of increase fixed pulley group and depression bar.
In order better to understand technology contents of the present utility model, below by this dynamic compaction machinery fixed pulley assembling distribution structure referred to as this structure.
The depression bar of this structure is a U-shaped bar, comprise the first parallel body of rod and second body of rod, be connected the pipe link of first body of rod and second body of rod, distance between first body of rod and second body of rod is greater than two distances between pull bar, anchor shaft has extension to two pull bar outsides, the anchor shaft two ends are supported on respectively the first body of rod top and the second body of rod top, normal-running fit between anchor shaft and depression bar; After adopting such structure, the mounting structure of depression bar is more reasonable.
Be provided with spacing sleeve between adjacent two pulleys in the fixed pulley group of this structure; After adopting such structure, reduce the friction between pulley.

The specific embodiment
Further illustrate the utility model below in conjunction with accompanying drawing and by embodiment:
As shown in Fig. 2 to 5
Depression bar 1 is a U-shaped bar, comprise first body of rod 11, second body of rod 12 and pipe link 13, first body of rod 11 is parallel with second body of rod 12, pipe link 13 connects the first body of rod 11 upper ends and the second body of rod 12 upper ends, and the middle part of first body of rod 11 and second body of rod 12 and bottom are fixedly connected with two strut bars 14.
The pull bar of two parallel placements is respectively that the first pull bar 21 and the second pull bar 22, the first pull bars 21 and the second pull bar 22 are respectively between first body of rod 11 and second body of rod 12 in depression bar 1.
Anchor shaft 3 successively level through first body of rod 11, the first pull bar 21, second pull bar 22 second bodies of rod 12, and anchor shaft 3 two ends by bearings on the first body of rod 11 tops and the second body of rod 12 tops.
Fixed pulley group 4 is arranged on the anchor shaft 3 between the first pull bar 21 and the second pull bar 22, five parallel placement fixed pulleys 41 are arranged in fixed pulley group 4, pass through bearing fit between each fixed pulley 41 and anchor shaft 3, and between adjacent two fixed pulleys 41, spacing sleeve 42 is arranged.
During use, variable-amplitude steel wire rope 6 is wrapped on fixed pulley group 4 and running block 5, regulate the distance between fixed pulley groups 4 and running block 5 by tightening up or discharging variable-amplitude steel wire rope 6, when working, strong rammer fallen suddenly by hammer ram, the layback of coxopodite arm, between fixed pulley group 4 and running block 5, distance diminishes, and fixed pulley group 4 is subject to the support of depression bar 1 and the first pull bar 21 and the second pull bar 22, huge change can not occur in position, can not interfere with adjacent mechanism yet.
