Detailed description of the invention
As shown in Figure 1, be eight rope hoisting mechanism for trolleys of the container handling crane that the utility model discloses, comprise trolley frame 1, first reel 2, second reel 3, actuating device 4 and suspension bracket 5.
First reel 2 and the second reel 3 are arranged on trolley frame 1, and actuating device 4 provides power for the first reel 2 and the second reel 3, and actuating device 4 adopts drive motor to drive.
Each winding four steel ropes on first reel 2 and the second reel 3, the two ends of suspension bracket 5 four sides are respectively provided with a pulley 6.
After every root steel rope walks around pulley 6, the free end 8 of steel rope is fixedly mounted on trolley frame 1, and eight steel ropes form eight congruent triangles.
Pulley 6 is arranged on suspension bracket 5 four angles, four upper steel ropes of the same reel of so easy layout, thus be easy to form congruent triangles, each reel controls 2 angles simultaneously, when only having a reel folding and unfolding steel rope, also can realize the function that tilts of suspension bracket 5, without the need to arranging the device that tilts in addition.
Pulley 6 is arranged on suspension bracket 5 four sides, suspension bracket 5 orientation different is all around made all to be subject to the counteracting forces of steel rope, therefore suspension bracket 5 can not rock when moving with dolly or cart, and every root steel rope all forms the triangle of congruence, the therefore uniform force of eight steel ropes.Eight steel ropes also use as hoist rope simultaneously.
Wherein two steel ropes are walked around after suspension bracket 5 is positioned at two pulleys 6 of same side, and arranged crosswise is arranged on trolley frame 1, and because the profile size of trolley frame 1 is limited, the structure of this arranged crosswise can save space.
As shown in Figures 2 and 3, above-mentioned trolley frame 1 is provided with steel-cable suspensioning device 7, this steel-cable suspensioning device 7 comprises steel rope permanent seat, pull bar 71 and pull bar permanent seat 72, steel rope permanent seat is fixed on the lower end of pull bar 71 by pinned connection, pull bar 71 is pivotally arranged on pull bar permanent seat 72, the free end of steel rope is fixedly mounted on steel rope permanent seat, and pull bar permanent seat 72 is fixed on trolley frame 1.Because suspension bracket 5 is often lifting, therefore rotating steel-cable suspensioning device 7, can prevent steel rope to be subject to the effect of breaking force.
Wherein steel rope permanent seat is wedge lock tube 73, and steel rope is arranged on wedge lock tube 73 in the mode of wedge joint, and wedge joint has fixed, is easy to dismounting, is convenient to the feature of maintain and replace.
Pull bar permanent seat 72 comprises bearing seat 721, bearing 722 and axle block 723, axle block 723 be each side formed one protrude axle 7231, two protrude axle 7231 and are arranged on bearing seat 721 respectively by bearing 722, and axle block 723 can be rotated around bearing seat 721 by said structure.Application force again due to steel rope is general all larger, therefore bearing 722 oscillating bearing that adopts holding capacity large, and oscillating bearing can also meet the feature that still can work on when oscillating bearing and axle decentraction.
The upper and lower sides of axle block 723 is formed with through hole, pull bar 71 upper end is long threaded column 711, this long threaded column 711 is fixed on axle block 723 through after this through hole by nut 724, after eight steel ropes walk around, in order to ensure the level of suspension bracket 5, often the installation site of steel rope is finely tuned, above-mentioned adjustment can be completed by the length of the long threaded column of nut 724 precession 711.
Because pull bar 71 is threaded connection to be fixed on axle block 723, therefore the torsion of pull bar 71 can make twisting resistance concentrate on threaded connection place, the reliability of connection can be affected for a long time, therefore between nut 724 and axle block 723, thrust articulated bearing 725 is also installed, by thrust articulated bearing 725 can make pull bar 71 and nut 724 can together with rotate, thus discharge this twisting resistance, but it is fixing not affect with axle block 723.
Certainly the change of team of steel rope affects its service life, in order to prevent steel rope around own rotation, square tube 7233 has been extended to form downwards on the downside of above-mentioned axle block 723, square tube 7233 center is square through hole, corresponding pull bar 71 is formed with the square pole 712 be plugged in this square through hole, because square tube 7233 can only be rotated in bearing 722 with axle block 723, and can not rotation, therefore the rectangle pair consisted of square tube 7233 and pull bar 71 can prevent pull bar 71 rotation, thus prevents steel rope rotation.Simultaneously due to the making of square tube 7233 and square pole 712 existing error, also have the existence in gap, therefore pull bar 71 still has the rotation at micro-angle, also can eliminate this twisting resistance by the structure of above-mentioned thrust articulated bearing 725.
Above-mentioned bearing seat 721 is split type, is divided into base 7211 and upper cover 7212, is easy to dismounting, is convenient to maintain and replace.
These are only preferred embodiment of the present utility model, the restriction not to protection domain of the present utility model.All equivalent variations done according to the mentality of designing of this case, all fall into the protection domain of this case.
