Description

Big-turning-angle sling for face-up transporting hoist of container

The design's technical scheme belongs to the suspender of the construction machinery and equipment container face crane of transportation loading and unloading freight container.

The suspender of the suspension transferring machine of prior art, the degreeof turn scope when handling is less.General drive mechanism is that hydraulic ram drives the revolution that eccentric stiffener driving suspender is made certain angle.Domestic, Southwest Jiaotong University's design-calculated suspender corner is between 112 degree are spent to 115.Abroad, the product of Italian Belau base of a fruit company also can only turn 90 degrees on a left side, turn right 30 degree, the i.e. angle range of 120 degree.At the scene in the operation,, influence operating efficiency, be a thing that bothers very much the suspension transferring machine driver because suspender has angle range little.

The task of the design's technical scheme provides a kind of suspender of new structure, makes the suspender of suspension transferring machine can do big corner rotation, promptly big corner suspender.Its anglec of rotation is rotated arbitrarily in the scope of right three-sixth turn in left three-sixth turn.

Its advantage is suspender simple in structure of more original 115 degree or 120 degree corners, and can do a left side 360 degree, and right 360 degree rotations have wide range of applications, and improve container handling, the operating efficiency of handling.Alleviate driver's labour intensity.

In order to realize above-mentioned task, following scheme has been proposed:

1, oil cylinder is as propulsion source, drives chain drive sprocket wheel, is fixed on the sprocket wheel rotating band moving axis on the axle and the H-girder of suspender and rotates.

2, oil cylinder drives tooth bar as propulsion source, and driven wheel drives axle and rotates with H-girder.

These two kinds of methods are all effective, but structure and transmission are all complicated, and the rotating part of suspender is too huge.

3, oil motor drives planet circular system, drives axle and rotates with H-girder, and just planet circular system working accuracy and matching requirements are all higher, and drive mechanism complexity, heaviness and self-locking performance are relatively poor.

Above-mentioned in a word method is all effective, still, the complex structure of suspender, cost height, its result of use is also inferior to following proposal.

Following technical scheme is structurally simple, and reliable transmission is effective.

The suspender casing is fixed on the transverse axis, bumps under the effect of cutting down control with electricity at the oil cylinder of only putting on the suspension transferring machine crane arm, and the axis hole axis on crane arm can forward and backward swing.Assembling sidesway crossbeam in the housing of suspender casing, the sidesway beam supporting produces cross travel under the effect of sidesway oil cylinder on roller shaft, and control its shift length and stationkeeping by the sidesway oil cylinder.The center of sidesway crossbeam is by suspended axle and fixing axis of revolution of the vertical assembling of guide pin bushing, H-girder is supported by pair of bearings in lower end at axis of revolution, worm gear of assembling and worm screw are formed the revolution transmission between two bearings, by the fluid motor-driven worm screw, the worm drive pair makes H-girder produce the revolution of spending greater than 180.Theoretically, can realize left three-sixth turn, right three-sixth turn.

Because adopt the worm and gear transmission, the degreeof turn of H-girder can be realized left and right three-sixth turn theoretically, its structure also is the simplest in the various schemes, and the process and assemble accuracy requirement is not high.A kind of left-hand rotation 95 degree have been provided in the design's the technical scheme, the i.e. example of 280 degree corners of 185 degree of turning right.It is according to the actual job needs of present general-duty suspension transferring machine and design-calculated.Concrete structure is with reference to accompanying drawing.
