Technical field

The utility model relates to the rolling of metallurgical manufacture band and handles the transportation device of the roll coil of strip in the line, particularly a kind of hydraulically powered coil of strip step rate conveyer.

Background technology

At present, known hydraulically powered step rate conveyer generally adopts hydraulic actuating cylinder-eccentric wheel and synchronizing bar to realize lifting, road wheel is walked in orbit, as shown in Fig. 1 and Fig. 2, track 4 is installed on the steel structure track girder 14, and the steel structure girder of track and saddle 5 are installed in again on the huge steel structure support 15.Moving beam and hydraulic actuating cylinder-eccentric wheel and synchronizing bar lifting structure are when work, owing to can in these members, produce bigger stress, and line of tension is longer, thereby there is bigger distortion, this will cause the distortion of moving beam and the quick wearing and tearing of hinged member, lead the actuation beam sideslip, when serious even accident such as can take place that road wheel derailing, the roll coil of strip are tumbled.

The utility model content

In order to overcome the shortcoming of above-mentioned existing step rate conveyer, task of the present utility model provides a kind of improved coil of strip step rate conveyer, directly realize lifting by lifting hydraulic cylinder, solved above-mentioned member and had moderate finite deformation, the problem of industrial accident takes place thus because of producing big stress.

Technical solution of the present utility model is as follows:

A kind of coil of strip step rate conveyer, it comprises hydraulic drive mechanism, moving beam, track and the saddle of depositing the roll coil of strip, road wheel is walked in orbit, it is characterized in that, this step rate conveyer has been cancelled the steel structure support that track, track girder and saddle are housed, the saddle of depositing the roll coil of strip directly is fixed on the reinforced concrete foundation, and track directly is fixed on the pre-embedded steel slab in the reinforced concrete foundation;

Described hydraulic drive mechanism comprises two above lifting hydraulic cylinders of cover and a cover horizontal hydraulic cylinder, head at the lifting hydraulic cylinder piston rod is equipped with cylinder elements, the horizontal hydraulic pressure cylinder head is connected on the moving beam, and lifting hydraulic cylinder and horizontal hydraulic cylinder drive moving beam respectively and carry out work;

The both sides of described moving beam have additional the upright guide wheel of array adjustable clearance.

The utility model is taked following further technical measures:

Described upright guide wheel is equipped with support, eccentric bushing, bearing and guide wheel, and eccentric bushing, bearing and guide wheel are connected with support, and support is installed on the moving beam.

Coil of strip step rate conveyer of the present utility model adopts two covers or the two above lifting hydraulic cylinders of cover and the moving beam of a cover horizontal hydraulic cylinder driving to carry out work, and in order to reduce steel structure support, has increased the upright guide wheel of many groups adjustable clearance in the both sides of moving beam.

Coil of strip step rate conveyer of the present utility model is applicable to the rolling of band and handles the transportation of the roll coil of strip in the line, it is simple and reliable for structure, weight is lighter, has saved investment, and has solved the problem that gross distortion and wearing and tearing and sideslip take place common step rate easily.

The beneficial effect of coil of strip step rate conveyer of the present utility model is: reduced weight of equipment significantly, thereby invested lessly, device structure is simple, and is convenient for installation and maintenance, solved the sideslip problem of step rate conveyer well.

The specific embodiment

Referring to Fig. 3 to Fig. 8, the utility model is a kind of coil of strip step rate conveyer, total has been cancelled original steel structure support 15, original steel structure support 15 is equipped with track 4, track girder 14 and saddle 5, therefore this conveyer saddle 5 that will deposit the roll coil of strip directly is fixed on the reinforced concrete foundation, track 4 directly is fixed on the pre-embedded steel slab in the reinforced concrete foundation, and road wheel is walked on track 4.

The hydraulic drive mechanism of this conveyer comprises two covers and two above lifting hydraulic cylinders 1 of cover and a cover horizontal hydraulic cylinder 2, as shown in Figure 7, head at lifting hydraulic cylinder 1 piston rod is installed cylinder elements 12, horizontal hydraulic cylinder 2 heads are connected on the moving beam, and lifting hydraulic cylinder 1 and horizontal hydraulic cylinder 2 drive moving beam respectively and carry out work.Number in the figure 6 is the first moving beam, and 7 is the second moving beam.Lifting hydraulic cylinder 1 is directly realized the lifting action of conveyer, and the head installing cylinder elements 12 at lifting hydraulic cylinder 1 piston rod can make connecting pin avoid very big vertical power, and install and remove easy to maintenance.

In order to reduce steel structure support, as shown in Figure 8, set up the upright guide wheel 3 of many groups adjustable clearance in the both sides of moving beam.Upright guide wheel 3 is equipped with support 8, eccentric bushing 9, bearing 10 and guide wheel 11, and eccentric bushing 9, bearing 10 and guide wheel 11 are connected with support 8, and support 8 is installed on the moving beam.Upright guide wheel 3 can lead to moving beam.

Coil of strip step rate conveyer of the present utility model at work, when needs lift coil of strip, lifting hydraulic cylinder 1 action is also directly moved beam 6, the second moving beam 7 by cylinder elements 12 rises first of its head, like this, the less roller pin 13 of size just need not be born the normal load of heavy weight coil of strip and moving beam.When conveyer advanced or retreat, by horizontal hydraulic cylinder 2 actions, directly the moving beam of promotion advanced or retreats, moving beam is by some groups of roller wheel bearings, the track 4 of roller walking directly is fixed on the pre-embedded steel slab of reinforced concrete foundation, and is led by 3 pairs of moving beams of upright guide wheel, to avoid moving beam sideslip.When moving beam descended, coil of strip just was placed on above the saddle 5 that is directly fixed on the reinforced concrete foundation reposefully.

Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim conversion, the modification of the foregoing description.
