Abstract
The utility model provides a groove earthwork refill device for a small-tonnage crawler crane. The device mainly comprises grab and pulleys, wherein a pulley is arranged between two arms of the grab, and a pulley is arranged at the top end of the pull rod of the grab; the grab is connected with a lifting arm of the crawler crane through one main steel wire rope; the other main steel wire rope penetrates through the two pulleys on the grab from bottom to top and is fixed on a cross beam of the grab; an adjusting pulley block is arranged on the lifting arm of the crawler crane and mainly comprises a connecting pulley and an adjusting pulley; one end of the connecting steel wire rope is connected with the lifting arm of the crawler crane, and the other end of the connecting steel wire rope passes by the connecting pulley and the adjusting pulley and is connected with the grab; and a balancing weight is arranged between the two pulleys of the adjusting pulley. The groove earthwork refill device has the positive effects of reducing the difficulty in refilling earthwork among multi-row extra-large diameter PCCP (pre-stressed concrete cylinder pipe) pipelines in the same groove, saving refilling cost and improving refilling efficiency.
Description
Technical field
The utility model relates to a kind of PCCP pipeline large span trench backfill device.
Background technology
In many rows install with groove super large caliber PCCP pipeline; often can run in the time of pipeline groove backfill; spacing between two pipes is less; and the distance construction scope of operation is far away; cannot use normal mechanical equipment to carry out a cubic meter backfill; because back fill building stones must be vertically put in backfill between pipe, and can not rely on the pipeline on both sides as platform discharging, more not allow mechanical equipment to travel installing back on the pipeline completing.If way adopts high-front shovel filler routinely, not only excavating machine hopper capacity is little, and telescopic boom falls short of, and can not meet site operation requirement, and work efficiency is extremely low, and quantity required is large, corresponding lease expenses costliness.
Summary of the invention
The purpose of this utility model is to provide that one can meet at a distance simultaneously, groove cubic metre of earth and stone backfilling apparatus among a small circle, cannot operate the problems such as high-front shovel lease rent costliness, inefficiency to solve many rows with groove super large caliber PCCP pipeline enclosure common mechanical.
The utility model mainly by grab bucket, pulley forms, and solves technical scheme that its technical matters adopts and be between two arms of grab bucket a pulley is set, and on the top of grab bucket pull bar, a pulley is set; Grab bucket is connected with crawler crane arm by a main rope, and another root main rope passes two pulleys in grab bucket from the bottom to top, and is fixed on the crossbeam of grab bucket; Adjustable pulley group is set on crawler crane arm, adjustable pulley group mainly forms by connecting pulley and adjustable pulley, connecting steel wire ropes one end crawler crane arm is connected, the other end is walked around connection pulley and is connected with grab bucket with adjustable pulley, between two pulleys of adjustable pulley, clump weight is set.
Adopt good effect of the present utility model to be: to reduce the difficulty of many rows with the backfill of the groove super large caliber PCCP pipeline enclosure cubic metre of earth and stone, saved backfill cost, improved backfill efficiency.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is structural representation of the present utility model;
In figure: 1 lifting wire rope, 2 connects pulley, 3 adjustable pulleys, 4 connecting steel wire ropes, 5 grab buckets, 6 backfill positions, 7 switch valve control steel ropes, 8 clump weights, 9 crawler cranes, 10 grab bucket pull bars.
Detailed description of the invention
As shown in the figure, between two arms of grab bucket 5, a pulley is set, on the top of grab bucket pull bar 10, a pulley is set; Grab bucket 5 is connected with crawler crane 9 arms by a main rope (lifting wire rope 1), and another root main rope (switch valve control steel rope 7) passes two pulleys in grab bucket 5 from the bottom to top, and is fixed on the crossbeam of grab bucket 5; On crawler crane 9 arms, adjustable pulley group is set, adjustable pulley group mainly forms by connecting pulley 2 and adjustable pulley 3, connecting steel wire ropes 4 one end are connected with crawler crane 9 arms, the other end is walked around connection pulley 2 and is connected with grab bucket 9 with adjustable pulley 3, between two pulleys of adjustable pulley 3, clump weight 8 is set, to stablize the swing of grab bucket.Control the lifting of grab bucket 5 by the folding and unfolding of lifting wire rope 1, control grab bucket 5 by switch valve control steel rope 7 and capture earth and stone material, while moving to backfill position 6, earth material is transferred.
