Technical field

The utility model belongs to the weight-lifting equipment field; Relate to a kind of lifting device: the row of hanging.

Background technology

The existing row of hanging has only the secondary equalizing bar, has no driving, leans on the rotation of manual operation secondary equalizing bar fully, wastes time and energy, and danger coefficient is big, lifts by crane the in light weight of object; Because suspension centre has only two suspension centres on the secondary equalizing bar, can not satisfy the lifting operation of a plurality of suspension centres, limitation is very big; The state of equilibrium of equalizing bar shows that by balanced pointers operating personal is at the state of equilibrium that can't observe the one-level equalizing bar at a distance, and there is potential safety hazard in lifting operation.Because the developing rapidly of ship building industry, the weight of lifting object is increasing, to hoisting sling require increasingly highly, the existing row of hanging more and more can not accomplish the needs of lifting operation safely, easily.

Summary of the invention

The purpose of the utility model is exactly to solve the problems referred to above that exist in the prior art, provides a kind of electronic rotation to hang row, and its lifting object is safer, easy to operate, can satisfy the lifting operation of a plurality of suspension centres, the Heavy Weight of lifting object.

For realizing above-mentioned purpose; The technical solution of the utility model is: row is hung in a kind of electronic rotation, and it comprises one-level equalizing bar, secondary equalizing bar, two three grades of equalizing bars, motor base, two motors, reductors, be installed in telltale, annunciator, remote controller in the operator's compartment, be installed in the level inclination sensor on the one-level equalizing bar; The one-level equalizing bar is connected through S. A. with the secondary equalizing bar; The upper end of S. A. rotatably maintenance on the lifting beam with hook of one-level equalizing bar; The lower end is hinged on the otic placode of secondary equalizing bar; The centre pass through motor base and rotatably maintenance in motor base, be fixed with motor on the motor base of S. A. both sides respectively, through power-transfer clutch and electric machine main shaft bonded assembly reductor be fixed on the miniature gears on the reductor main shaft; Be fixed with big gear wheel on the S. A., big gear wheel respectively with two pinion; Two suspension centres of secondary equalizing bar lower end are hinged through the hook of down suspension hook and two three grades of equalizing bars respectively, and each suspension centre and each coaster that are uniformly distributed with on three grades of equalizing bars are connected in series by steel rope; The signal output part of level inclination sensor connects telltale and annunciator respectively.

The terminal part of above-mentioned described steel rope adopts wedge joint.Because the terminal part of steel rope adopts wedge joint; After steel rope can pass the coaster that assembles easily; Be through in the wedge joint again, so the utility model can be after assembling coaster, the good steel rope of assembled in series conveniently again; Reeve is quick and convenient, for later period maintenance more change steel rope also bring great convenience.

There is screw thread the upper end of above-mentioned described S. A., and it passes through the lifting beam with hook of one-level equalizing bar, and by the nut locking maintenance on the lifting beam with hook of one-level equalizing bar, between the lifting beam with hook of nut, S. A. upper end and one-level equalizing bar, head bearing is being installed; Have the pin shaft hole that is complementary on the last hanging axis of the lower end of S. A. and secondary equalizing bar, the two is fixed together by bearing pin; Motor base is passed through in the centre of S. A., and between the motor base lower bearing is installed.

Owing to be equipped with the Dual-motors Driving device on the secondary equalizing bar of the utility model, the secondary equalizing bar can be realized 360 ° of rotations automatically, and is time saving and energy saving, the Heavy Weight of lifting object; Each motor driver can co-ordination, can work independently separately again and not disturb mutually, and when motor et out of order wherein, another motor-driven can continue normal operation, accomplishes rotary manipulation, and the rotation reliability is high.The utility model has increased by two three grades of equalizing bars, and each suspension centre and each coaster are connected in series by steel rope, can make each point of connection stressed evenly, and structure is small and exquisite according to any alternative point of contact of workpiece needs of lifting.The utility model has increased the level inclination sensor, when one-level equalizing bar over balance warning angle, and level inclination sensor auto alarm, the operating personal of operator's compartment makes it to be in state of equilibrium through the diff-H of the adjustment of the data on read-out suspension hook.Wedge joint is adopted in the end of the utility model steel rope, can be after assembling coaster, and the good steel rope of assembled in series is conveniently changed steel rope for later period maintenance and is brought great convenience again.The utility model especially is fit to be applied in 550 tons of rows of hanging.
