Abstract
The utility model relates to a guiding device of a semiconductor type diaphragm wall grab bucket lifting steel wire rope. A double-groove pulley guide device is arranged between a fixed pulley and a movable pulley of the semiconductor type diaphragm wall grab bucket lifting steel wire rope, the double-groove pulley guide device is composed of two oppositely arranged double-groove pulley mechanisms, two branch steel wire ropes of the lifting steel wire rope are respectively penetrates inside adjacent rope grooves of the two double-groove pulley mechanisms, and the branch steel wire ropes are separately arranged in double grooves of the two pulleys. According to the guiding device of the semiconductor type diaphragm wall grab bucket lifting steel wire rope, the two double-groove pulley mechanisms with the same structure are oppositely arranged between the fixed pulley on the top of an arm head and the movable pulley on the lower portion of a first level guide bar, the pulley shafts are fixed on the first level guide bar, the two branch steel wire ropes of the lifting steel wire rope are lifted in double times to respectively penetrate through one pulley groove, and the two grooves of the double-groove pulley enable the two branch steel wire ropes to be separated from each other and form two mutually non-intersecting spatial straight lines, the movable pulley steers along with a grab bucket by 180 degrees, the two branch steel wire ropes are no longer intersected in a plane, and thus abrasion is effectively controlled, and the service life of the semiconductor type diaphragm wall grab bucket lifting steel wire rope is exponentially prolonged.
Description
One, technical field
The utility model relates to a kind of guiding device of half conduction continuous wall grab boom hoist cable, guiding and abrasionproof when being mainly used in proposing the folding and unfolding of bucket wire rope in half conduction hydraulic diaphragm wall grab work progress.
Two, background technology
In half conduction continuous wall grab operation process, guide rod need to turn to 180 ° around guide rod vertical centre axis (Z axis) repeatedly with grab bucket, carries out left and right two lobe grab bucket exchange digging operations.In guide rod and 180 ° of steering procedures of grab bucket, it is motionless that 2 fixed pulleys that boom hoist cable is walked around are fixed on jib top, and the movable pulley that is arranged on one-level guide rod bottom frequently rotates 180 ° around Z axis with guide rod and grab bucket.Be at grade intersection by two branch's wire rope that fixed pulley is wound into the boom hoist cable that originally is parallel to each other on movable pulley this moment, partly is screwed in together.In the process of grab bucket lifting, wire rope folding and unfolding, the wire rope of intersection is in contact with one another friction, wearing and tearing, fracture of wire occur and scraps.
Three, summary of the invention
After the purpose of this utility model was to provide a kind of movable pulley that can make half conduction continuous wall grab and turns to 180 ° of guide rods, two branch's wire rope were separated from each other, and prevented that it from intersecting the guiding device of half conduction continuous wall grab boom hoist cable of wearing and tearing.
The technical scheme of employing of the present utility model is: between the fixed pulley of half conduction continuous wall grab boom hoist cable and movable pulley, the double grooved pulley guiding device is set, the double grooved pulley guiding device is made of relative two double grooved pulley mechanisms; Two branch's wire rope of boom hoist cable are through in the adjacent grooving of two double grooved pulley mechanisms, and two branch's wire rope are separated in the double flute of two pulleys.
The utility model is relatively installed two the identical double grooved pulley of structure mechanisms, and its wheel shaft is fixed on the one-level guide rod between the movable pulley of the fixed pulley at arm head top and one-level guide rod bottom.Two branch's wire rope of 2 multiplying power boom hoist cables respectively pass a race, and two races of double grooved pulley make two steel cables be separated from each other, become two mutually disjoint space lines.Movable pulley turns to 180 ° with grab bucket, and wire rope is at grade intersection no longer, thereby has effectively controlled wearing and tearing, has increased exponentially the application life of wire rope.The utility model also has good sealing and lubricity, thereby has effectively guaranteed the safety of its operation in muddy water.
Four, description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the structural representation of double grooved pulley of the present utility model mechanism.
Five, the specific embodiment
Double grooved pulley of the present utility model mechanism is made of double grooved pulley 1, bearing 2, axle sleeve 3, axle 4, end cap 5 and rotating seal ring 6, the endoporus of axle sleeve 3 matches with axle 4, axle sleeve 3 is outer ladder cylindrical sleeves of a two ends symmetry, two rolling bearings 2 are housed on the external cylindrical surface of sleeve, insert in the endoporus of double grooved pulleys 1 with the axle sleeve 3 of bearing 2; The end cap 5 that rotating seal ring 6 is housed is enclosed within axle sleeve 3 two ends, and is fixed by bolts on double grooved pulley 1; Rotating seal ring 6 makes double grooved pulley mechanism have good waterproof and dustproof performance, injects lubrication oil by lubricating cup 7, and it is rotated freely, thereby has effectively guaranteed the safety of its operation in muddy water.Two double grooved pulley mechanisms are arranged in the middle of one-level guide rod 10 relatively.Two double grooved pulley cylindrical spacings are the 5mm left and right, guarantee that wire rope is arranged in the gathering sill of two double grooved pulley Mechanism Combinations all the time.Boom hoist cable 9 passes in a race of double grooved pulley from top to bottom by a fixed pulley on arm head, then another root steel cable branch that walks around movable pulley passes another grooving of double grooved pulley from bottom to up, afterwards by fixing end after another fixed pulley on arm head.
