Detailed Description
Example one
Referring to fig. 2-4, the present invention provides an anti-rotation device for an earth box, which is disposed on a boom of a crane, and comprises a fixed guide wheel 4, a pull rope 5, a weight block 6, at least one fixed pulley 7, and at least one movable pulley 8 fixedly connected to the weight block 6.
The fixed guide wheel 4 is fixedly connected with the lower end of the crane boom, the fixed pulley 7 is fixedly connected with the upper end of the crane boom, one end of the pull rope 5 is fixedly connected with the soil box 1, and the pull rope 5 between the fixed guide wheel 4 and the soil box 1 has a certain included angle with the hoisting direction of the crane, so that the pull force generated by the counterweight block 6 to the soil box 1 through the pull rope 5 has a component force perpendicular to the hoisting direction, when the soil box 1 has a rotating trend, the moment formed by the component force pulls the soil box 1, the soil box 1 is prevented from rotating, the mutual winding of lifting ropes of two hooks of the crane can be avoided, and the soil residue hoisting efficiency is improved.
One end of the pull rope 5 far away from the soil box 1 sequentially winds through the fixed guide wheel 4, the fixed pulley 7 and the movable pulley 8, and then the end part of the pull rope is fixedly connected with the movable pulley 8 or the fixed pulley 7.
In this embodiment, referring to fig. 4, the number of the fixed pulleys 7 and the movable pulleys 8 is one, one end of the pull rope 5, which is far away from the soil box 1, sequentially passes through the fixed guide wheel 4, the fixed pulleys 7 and the movable pulleys 8, and passes through the fixed pulleys 7 again, and then the end of the pull rope is fixedly connected with the movable pulleys 8, it is worth explaining that the pull rope 5 and the pull rope 5 are arranged in a rope winding manner to be matched, and according to the stress analysis of the pulley block, the arrangement can make the pulling force generated by the pull rope 5 on the soil box 1 be 1/3 of the weight of the counterweight block 6, so that the component force of the pulling force perpendicular to the lifting direction can be ensured to avoid the rotation of the soil box, and the influence of the component force parallel to the lifting direction on the vertical movement of the soil box can also be reduced.
In this embodiment, a movable guide wheel 9 is fixedly connected to one side of the counterweight block 6, a guide rope 10 is arranged on the boom, and the guide rope 10 is wound on the movable guide wheel 9, so that the movable guide wheel 9 slides along the guide rope 10, and the counterweight block 6 is prevented from shaking in the up-down moving process.
Referring to fig. 3, the soil box 1 is provided with two connection points for connecting with the pull rope 5, and the two connection points are located at two side edges of the same surface of the soil box 1, so that the soil box 1 is uniformly stressed, and the stability of the soil box 1 is ensured.
The working principle of the utility model is as follows: when the soil box 1 is lifted, the soil box 1 rises, the balancing weight 6 moves downwards under the action of self weight, meanwhile, the balancing weight 6 generates tension on the soil box 1 to prevent the soil box 1 from rotating, when the movable guide wheel 9 slides to the lowest end of the guide rope 10, the movable guide wheel cannot move downwards, the soil box 1 moves upwards, one end of the movable guide wheel is in a loose state by the stay cord 5 between the soil box 1 and the fixed guide wheel 4, and then the tension on the soil box 1 by the balancing weight 6 can be relieved, so that soil residues can be poured conveniently; when empty soil box 1 below the same reason, stay cord 5 pulling balancing weight 6 rises promptly, and stay cord 5 produces the pulling force to soil box 1 simultaneously and avoids soil box 1 rotatory.
Example two
In this embodiment, the number of the fixed pulleys 7 and the number of the movable pulleys 8 are also one, referring to fig. 5, the difference between this embodiment and this embodiment is that the rope winding manner of the rope 5 is different, specifically, after one end of the rope 5, which is far away from the soil box 1, sequentially winds around the fixed guide wheel 4, the fixed pulleys 7 and the movable pulleys 8, the end part is fixedly connected with the fixed pulleys 7; according to the force analysis of the pulley block, the arrangement can ensure that the pulling force generated by the pulling rope 5 on the soil box 1 is 1/2 of the weight of the balancing weight 6.
EXAMPLE III
Referring to fig. 6, the embodiment is different from the first embodiment in that the number of the fixed pulleys 7 is two, the fixed pulleys are a first fixed pulley 701 and a second fixed pulley 702 respectively, the number of the movable pulley 8 is one, one end of the pull rope 5 far away from the soil box 1 sequentially passes through the fixed guide wheel 4, the first fixed pulley 701, the movable pulley 8 and the second fixed pulley 702, and then the end is fixedly connected with the movable pulley 8; according to the force analysis of the pulley block, the arrangement can also ensure that the pulling force generated by the pulling rope 5 on the soil box 1 is 1/3 of the weight of the balancing weight 6.
Example four
Referring to fig. 7, a difference between the present embodiment and the first embodiment is that the number of the fixed pulleys 7 and the number of the movable pulleys 8 are two, the fixed pulleys 7 are respectively a first fixed pulley 701 and a second fixed pulley 702, the movable pulleys 8 are respectively a first movable pulley 801 and a second movable pulley 802, one end of the pull rope 5 away from the soil box 1 sequentially passes through the fixed guide pulley 4, the first fixed pulley 701, the first movable pulley 801, the second fixed pulley 702 and the second movable pulley 802, and then the end is fixedly connected to the second fixed pulley 702; this results in the pulling force exerted by the pull rope 5 on the soil box 1 being 1/4 times the weight of the counterweight 6.
In conclusion, according to actual needs, the number of the movable pulleys 8 and the fixed pulleys 7 and the rope winding mode of the pull rope 5 can be changed, so that the reduction or the increase of the tensile force generated by the counterweight block 6 on the soil box 1 can be realized.
The utility model also provides a hoist is equipped with above-mentioned soil box rotation preventing device on the jib loading boom of hoist.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art.
