Description

Isosceles triangle Torque distribution device with pulley

Technical field

The utility model relates to a kind of isosceles triangle Torque distribution device with pulley, belongs to hanging device technical field.

Background technique

Currently, in crane hanging component work progress, it is frequently present of docking for suspended object and other structures.According to applying in the past Work, because suspended object can not be precisely in place according to theoretical calculation in the docking of hoisting process, there are certain deviations.Actually hanging It can be because the deviation causes suspended object Current Collector Sleave during dropping place the case where side does not stress occur in dress.Cause crane pair Suspended object carries out oblique pull.The situation is not allow to occur in construction reference.Especially in the lifting of large-tonnage grade, hundred tonnes Oblique pulling there are quite high security risks.

Utility model content

The purpose of the utility model is to provide a kind of isosceles triangle Torque distribution device with pulley, can by pulley with And the cooperation of pin shaft changes stress, enables hoist cable uniform force, can satisfy large-tonnage grade lifting construction.

The isosceles triangle Torque distribution device of extruded tapes pulley described in the utility model, including mainboard, mainboard include corresponding to Built-in ribs is equipped with inside the upper mainboard and lower mainboard being arranged, upper mainboard and lower mainboard, mainboard top is equipped with upper hole stiffening ring, Mainboard lower part is equipped with lower opening stiffening ring, is connected with top bearing pin by top sheave between upper hole stiffening ring, between lower opening stiffening ring Bottom bearing pin is connected with by lower sheave.By subregional Torque distribution device, replace traditional hoist cable, so that large-tonnage lifts When construction, can balancing gravity influence, avoid the occurrence of hoisting rig and the case where side does not stress occur.

The quantity of upper hole stiffening ring is 1 on the mainboard, and the quantity of lower opening stiffening ring is 2 on mainboard.It can be simultaneously Guarantee connect two riggings, due to pulley can equilibrant force, can also only mount a rigging.

The center of the upper hole stiffening ring is equidistant to two lower opening reinforcement circle centers.Under upper hole stiffening ring and two Hole stiffening ring is placed in isosceles triangle, so that being more uniformly stressed.

The angle that the center of described two lower opening stiffening rings and upper hole reinforcement circle center surround is 10-150 degree.

External stiffening plate is equipped with outside the upper mainboard and lower mainboard.For further fixing, mainboard is under in locking The relative position of mainboard.

The built-in ribs is placed in flabellum shape perpendicular to mainboard, and is distributed in hole stiffening ring and lower opening stiffening ring Between.Space between mainboard is divided into non-interference three parts by built-in ribs, increases the convenience that the device uses.

Compared with prior art, the utility model has the beneficial effects that

1, the isosceles triangle Torque distribution device described in the utility model with pulley can pass through pulley and pin shaft Cooperation changes stress, enables hoist cable uniform force, can satisfy large-tonnage grade lifting construction.

2, it by using this device, using the Torque distribution principle of its triangle, solves in lifting construction because of deviation So that suspended object Current Collector Sleave during dropping place the case where side stress does not stress is occurred, the lifting of large-tonnage grade can be better met Construction.

3, triangular in shape between upper hole stiffening ring and lower opening stiffening ring, keep apparatus structure more firm, is more uniformly stressed, Construction safety is fully ensured that, and relative reduction difficulty of construction.

Specific embodiment

Embodiment 1

As shown in Figure 1, the embodiment of the isosceles triangle Torque distribution device described in the utility model with pulley, including master Plate, mainboard include the upper mainboard 1 being correspondingly arranged and lower mainboard 9, and built-in ribs 5 is equipped with inside upper mainboard 1 and lower mainboard 9, main Plate top is equipped with upper hole stiffening ring 2, and mainboard lower part is equipped with lower opening stiffening ring 3, is connected between upper hole stiffening ring 2 by top sheave Top bearing pin 6 is connected with bottom bearing pin 7 by lower sheave 8 between lower opening stiffening ring 3.In use, the connection balance of top bearing pin 4 Beam, 7 butt rigging of bottom bearing pin, and upper mainboard 1 and lower 9 matching design of mainboard are triangle, and do corresponding circular arc processing.

The quantity of upper hole stiffening ring 2 is 1 on the mainboard, and the quantity of lower opening stiffening ring 3 is 2 on mainboard.

The center of the upper hole stiffening ring 2 is equidistant to two 3 centers of lower opening stiffening ring.Upper hole stiffening ring and two The center of lower opening stiffening ring constitutes an isosceles triangle.

The angle that the center of described two lower opening stiffening rings 3 and upper 2 center of hole stiffening ring surround is 10-150 degree.

External stiffening plate 4 is equipped with outside the upper mainboard 1 and lower mainboard 9.

The built-in ribs 5 is placed in flabellum shape perpendicular to mainboard, and is distributed in hole stiffening ring 2 and lower opening reinforcement Between circle 3.

The course of work or working principle:

In the specific use process, the top bearing pin 6 of the isosceles triangle Torque distribution device with pulley is connected into equalizer bar, 7 butt rigging of bottom bearing pin, during weight is lifted, according to the Torque distribution principle of triangle, by the stress of the device It is balanced, weight is enable smoothly to sling, fall, avoid the occurrence of weight and occur the feelings that side does not stress in dropping process Condition occurs.
