Description

Light hydraulic slave cranes for loading vehicle

The utility model is goods carrying vehicle light hydraulic truck-mounted crane, and a kind of have the light hydraulic of ascending, descending and revolute function handling goods with the car hoisting device.

The above goods of goods carrying vehicle loading and unloading 200kg mainly by wheel crane, insert mechanical equipment such as car or manually finish.The mechanical handling shipping cost is with high, and non-cutting time is long.Artificial handling goods, the staff is many, and labour intensity is big, and efficient is low.Many for this reason people have invented the goods carrying vehicle truck-mounted crane, and for example patent application 8920777.

The miniature lorry-mounted crane that patent application 8920777 provides is made up of column, outstanding rope, three rope pulley groups, lift system and swing type mechanism.Its constructional feature is, two joint columns and two joint cantilevers are arranged, and manual lifting mechanism and swing type mechanism that gear and tooth bar are formed are housed above.This lorry-mounted crane oad is bigger, inconvenient operation.

Equipment with hydraulic pressure truck-mounted crane of handling goods function mainly contains two kinds of forms, and a kind of is that upright arm is vertically mounted between the preceding sweep assembly of operator's compartment and railway carriage, and arm lies in a horizontal plane in above the operator's compartment; Another kind also is that upright arm is installed in midway location between the preceding sweep assembly of operator's compartment and railway carriage, and arm is placed on above the railway carriage, both handling goods all need be used hoisting system, rotate upright arm and need use hydraulic ram, auxiliary support apparatus all need be laid in the both sides of vehicle, complex structure, cost height, weight is heavier, and the capacity weight that accounts for vehicle is more.In addition, arm is placed in above the operator's compartment, has not only increased the oad of vehicle, and not attractive in appearance; Arm is placed in above the railway carriage, and the useful space that accounts for railway carriage is more, and the oad of restriction goods.

The purpose of this utility model is to provide the following goods of a kind of 500kg of loading and unloading, account for the useful space of railway carriage few, in light weight, account for the few light hydraulic truck-mounted crane of vehicle capacity weight.

The purpose of this utility model also is to provide a kind of arm that makes can left-right rotation, the equipment that can swing up and down again with respect to railway carriage.

Realize that above-mentioned purpose the utility model is not provided with hoisting system, vehicle side is to auxiliary support apparatus and rotate the parts such as oil cylinder that found arm, structure is simplified greatly, and weight significantly reduces, and it is few to account for the vehicle capacity weight, with low cost.

The equipment that the utility model provides, the preceding sweep assembly that utilizes vehicle, can be reinforced or be transformed as its undercapacity as upright arm.Support upper support seat or the lower support seat of upper support frame and support amplitude oil cylinder or the side that the lower support frame is installed in the preceding sweep assembly of railway carriage of arm, wherein the extended line of the center of gyration line of axis of revolution or revoliving arm coincides.Two orthogonal axles and a U-lag are set on axis of revolution or the revoliving arm, and the line of centers of two axles on the axis of revolution intersects at same plane, and the line of centers of two axles is not or not same plane on the revoliving arm.Specifically, two axles on the axis of revolution, an axle is placed perpendicular to carriage bottom plate, is connected with supporting seat, rotates with respect to supporting seat.Another axle is parallel to carriage bottom plate and places, be installed in an end of last axle, be connected with arm, the line of centers of diaxon intersects in same plane, two axles on the revoliving arm, an axle is placed perpendicular to carriage bottom plate, is fixed on the bracing frame, and revoliving arm rotates around this axle, another axle is parallel to carriage bottom plate and places, be fixed on the revoliving arm, be connected with arm, the line of centers of two axles is not at grade.Adopting the purpose of this structure, is to make the arm can left-right rotation with respect to railway carriage, can swing up and down again, and amplitude oil cylinder also can correspondingly be swung and rotate with arm, thereby realizes the function of handling goods.

In addition, a cam-type latching device is set, it comprises cam, Cam rest, adapter shaft and arm, a groove is arranged on the arm, cam passes this groove and contacts with telescopic boom, and when clockwise rotating cam, cam then is fastened on telescopic boom on the arm, when rotating counterclockwise cam, then unclamp telescopic boom.

At last, on structural arrangement, the lower position that arm swings up and down with respect to railway carriage, perpendicular to carriage bottom plate, the end position of left-right rotation can abut in a side of the preceding sweep assembly of railway carriage, compact conformation, it is few to account for the railway carriage space.

Further feature above-mentioned and of the present utility model has been done detailed introduction in the accompanying drawings together with the various details of structure, but the special embodiment shown in the accompanying drawing can not constitute restriction of the present utility model only for describing usefulness in detail.The utility model will be further described below in conjunction with accompanying drawing:
