In order further to improve rigidity and subsidiary load, among the described first fork cutter 7a, the second fork cutter 7b, trident cutter 7c and the 4th fork cutter 7d at least one be with respect to its corresponding first auxiliary girder 5a, the second auxiliary girder 5b, the 3rd auxiliary girder 5c and fourth officer beam 5d swing, the fork hook that makes this swing fork cutter to by the handling object space to moving.At this moment, between each fork cutter and each auxiliary girder, be formed with swing hinge 13.Each swing of pitching cutter can be adopted the mode of small angle oscillation.Preferred four fork cuttves all have the function of swing.Those skilled in the art can adopt various possible modes to carry out the swing of respectively pitching cutter, as adopting structures such as electrical components, mechanical part or hydraulic unit, preferably adopt the oscillating oil cylinder 8 shown in Fig. 1 b.

As a preferred embodiment of the present invention, in order to adapt to the goods of different size shape, distance between the first fork cutter 7a and the second fork cutter 7b can be adjusted between the 2500mm at 500mm, and this scope can be adjusted by the length of the first girder 4a and the collapsing length of the first auxiliary girder 5a, the second auxiliary girder 5b.In addition, the distance between the first fork cutter 7a and the trident cutter 7c can be adjusted between the 2500mm at 500mm, and this scope can be adjusted by the first girder 4a, the miles of relative movement of the second girder 4b on guide rail 10.The distances of two forks between the cuttves refer to when the knife bar of two fork cuttves is parallel, the distance between two parallel liness.

Suspender of the present invention when goods 14 (as ashlar) is placed on ground or the flat truck, can be lined with wooden 15 (shown in Fig. 1 b) below goods 14 in the loading and unloading operation process, this moment, goods 14 bottoms had certain clearance.By regulating the slippage of the first girder 4a, the second girder 4b, and the stroke of regulating the first auxiliary girder 5a, the second auxiliary girder 5b, the 3rd auxiliary girder 5c and fourth officer beam 5d, make the space that forms between the fork cutter 7a that wins, the second fork cutter 7b, trident cutter 7c and the 4th fork cutter 7d be fit to the oad of goods 14.At this moment, can nutation construction machinery and equipment such as front swing-machine, with the fork hook of each fork cutter below to the gap of quasi-goods 14 with areal of support.Then, further adjust the slippage of each girder or the stroke of each auxiliary girder, make and respectively pitch the gap that cutter enters goods 14 and areal of support.At this moment, further the oscillating oil cylinder 8 of cutter is respectively pitched in adjustment, makes the fork hook of respectively pitching cutter further draw close to goods 14.Afterwards, promptly can lift by crane the operation of transhipment.Unload by the process of handling thing just in time on the contrary, do not repeat them here.

Except aforementioned suspender, the present invention also provides a kind of construction machinery and equipment that comprises this suspender, and other structure of this project machinery is with reference to prior art, and this paper repeats no more.Preferred this project machinery is front swing-machine.

In sum, suspender of the present invention and construction machinery and equipment, by the moving forward and backward of each girder, the left and right sides telescopic moving of each auxiliary girder and the swing of respectively pitching cutter, the distance that each can be pitched between the cutter is adjusted to proper range, to be fit to the loading and unloading operation of different size goods.The present invention can also realize the rotation of suspender bottom by the rotation of turntable up and down, under the situation that does not need the mobile engineering machinery main frame, realizes the putting position of goods or the adjustment of lifting position.Compared with prior art, the present invention has the following advantages:

1) operating efficiency height

Suspender of the present invention and construction machinery and equipment by automation mechanized operation, can obviously improve the loading and unloading operation efficient of square body goods such as stone material.Work efficiency can increase to per hour stacks 20~50 blocks of stone materials.And, when being arranged on suspender of the present invention on the front swing-machine, not needing to make a jack and promptly can realize direct loading and unloading operation, can obviously save production time.

2) safe

Suspender of the present invention and construction machinery and equipment do not need manually to realize the pocket cover work of steel rope, have solved potential safety hazard, have improved processing safety.

3) save cost

Suspender of the present invention and construction machinery and equipment are abandoned instruments such as use " four gate stops " and steel rope, and the cost of having avoided causing because of the steel rope loss increases.

Therefore, the invention has the beneficial effects as follows conspicuous.

The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
