Abstract

The utility model discloses a winding system of a steel wire rope of a grabbing tool of a crane, which comprises a winding drum assembly, a movable pulley block arranged on the grabbing tool and a fixed pulley block fixed on a trolley frame, wherein the winding drum assembly is connected with the fixed pulley block through the steel wire rope passing through the movable pulley block, and the arrangement distance between the movable pulleys in the movable pulley block is set to be larger than that between the fixed pulleys in the fixed pulley block. The winding system of the steel wire rope of the grabbing tool of the crane can offset the action of the horizontal inertial load generated during the braking of the crane by utilizing the horizontal force generated by obliquely pulling the steel wire rope, so as to effectively prevent the lifting grabbing tool from oscillating during the operation of the crane, achieve the purpose of preventing the grabbing tool from oscillating, ensure the speed and the accuracy of grabbing and feeding the straw bag of the straw bag crane, and improve the work efficiency of the crane.

Description

Hoisting crane gripping apparatus steel cable winding system
Technical field
The utility model relates to the weight-lifting equipment technical field, particularly a kind of hoisting crane gripping apparatus steel cable winding system.
Background technology
The Straw bale hoisting crane grasps Straw bale by specific gripping apparatus, because the size of gripping apparatus is slender type (length * wide for 8.4m * 1.2m), hoisting drum is connected with gripping apparatus with assembly pulley by steel rope on the direction perpendicular to the hoisting crane operation.Steel rope is a flexible connector, and at the startup or the glancing impact of hoisting crane operation, because the effect of horizontal force of inertia, the common mode that is intertwined and connected gripping apparatus is very easy to produce swing, influences the extracting and the input of Straw bale, reduces the work efficiency of hoisting crane.The operating anti-sway problem of hoisting crane is considered in the designing requirement of this type of crane hoisting mechanism.
The utility model content
One of the purpose of this utility model provides a kind of hoisting crane gripping apparatus steel cable winding system of the swing of the gripping apparatus that hoists when preventing the hoisting crane operation.
Provide a kind of hoisting crane gripping apparatus steel cable winding system according to an aspect of the present utility model, comprising:
The reel group, be installed in the running block on the gripping apparatus and be fixed on fixed pulley group on the trolley frame; Described reel group relies on the described running block of steel wire penetrating to be connected with described fixed pulley group; In the described running block between the movable pulley be provided with the distance greater than the distance that is provided with between the fixed pulley group.
Described reel group comprises 2 reels.
Described running block comprises 4 movable pulleys.
Described fixed pulley group comprises 4 fixed pulleys.
Described steel rope is laid out, is wire-wrapped in described fixed pulley respectively by described movable pulley by the two ends of each reel respectively, and cross fixation is connected on the other beam of described movable pulley respectively again.
According to the hoisting crane gripping apparatus steel cable winding system that the utility model provides, the swing of the gripping apparatus that prevents to hoist when hoisting crane moves has guaranteed speed and accuracy that the Straw bale hoisting crane grasped and threw in Straw bale, has improved the work efficiency of hoisting crane.
Description of drawings
Fig. 1 is the structural representation of the hoisting crane gripping apparatus steel cable winding system that provides of the utility model embodiment;
Fig. 2 is the scheme drawing that steel rope twines in the system shown in Figure 1;
The utility model purpose, function and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.
The specific embodiment
As shown in Figure 1 and Figure 2, the hoisting crane gripping apparatus steel cable winding system that provides of the utility model embodiment comprises the reel group, is installed in the running block on the gripping apparatus and is fixed on fixed pulley group on the trolley frame.Reel group dependence steel rope (2) passes running block and is connected with the fixed pulley group.Trolley frame is the bearing support of crane carriage, and lifting mechanism (comprising the electrical motor that hoists, retarder, hoisting drum, fixed pulley etc.) is installed on the trolley frame; Crane carriage can move laterally (direction that crane track is vertical is moved on the track that is provided with on the crane girder).Wherein, the reel group comprises 2 double crosslinking drums (1).Running block comprises 4 movable pulleys (4).The fixed pulley group comprises 4 fixed pulleys (2).Steel rope (2) respectively by the two ends of each reel (1) lay out, by the movable pulley on the gripping apparatus (4) fixed pulley (3) on the wraparound trolley frame respectively again, at last respectively cross fixation on the other beam (5) of movable pulley on the gripping apparatus (4).The distance of fixed pulley should be bigger than the distance of movable pulley on the gripping apparatus on the trolley frame, to guarantee to form up big and down small tiltedly drawing.The horizontal force that oblique rollering steel silk rope (2) produces can be offset the effect of opening the horizontal inertia loading of glancing impact generation when hoisting crane, and the swing of gripping apparatus when hoisting crane moves that prevent from effectively to hoist reaches the anti-sway purpose of gripping apparatus.It should be noted that and want angle and the height that four steel ropes (2) lay out on two reels of strict control, make it in full accord, tilt to prevent gripping apparatus; The fixed end of four steel ropes (2) needs slightly off-center a bit, the interference when avoiding intersecting between the steel rope (2).
The utility model embodiment provide hoisting crane gripping apparatus steel cable winding system, can offset the effect of opening the horizontal inertia loading of glancing impact generation when hoisting crane by the horizontal force that oblique rollering steel silk rope produces, the gripping apparatus swing when hoisting crane moves effectively prevents to hoist, reach the anti-sway purpose of gripping apparatus, guarantee speed and accuracy that the Straw bale hoisting crane grasped and threw in Straw bale, improved the work efficiency of hoisting crane.
The foregoing description is the utility model preferred implementation; but embodiment of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under spirit of the present utility model and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
