Abstract
The utility model relates to a multi-heeling crane, which comprises a tower body, a cross beam and a fixed support. One end of the cross beam is connected with the tower body, the other end is connected with the fixed support, and the cross beam between the tower body and the fixed support is also supported with a movable support. Oing to the movable support supported on the cross beam of the tower body and the fixed support, the cross beam can partially lift and move material, and therefore, the actual span of the cross beam is shortened. The utility model not only can rduce the sectional dimension of the cross beam and material consumption, but also has convenient installation operation of the crane, and use safety performance is greatly increased. Meanwhile, the use span of the crane machine is extended, the span of the complete machine can be greatly increased, and the weight of the complete machine can not be increased.
Description
Technical field
The utility model belongs to the civil construction elevator machinery, relates in particular to the improvement of arm-type lifting appliance.
Background technology
In the civil construction construction, present widely used jib crane tool mainly is a tower crane, because there is the use cost height in tower crane, deficiencies such as shifting difficulty is installed and is difficult to be applicable to the rural area, the building operation of small-sized building such as small towns and dwelling house, Chinese patent (97207350.7) specification sheets discloses a kind of flexible tower hanging apparatus for this reason, if connecting, slinging beam one end of device is supported on the body of the tower, the other end then with stand on house wall on fixed support link to each other, this device constitutes similar crane in bridge type during use, thereby simplified structure, improved stability.But the overhead hoist of this structure, when the crossbeam span is excessive, because its span and its resistance to bending are inversely proportional to, its crossbeam load-carrying capacity descends significantly, therefore to realize that big span lift heavy has to strengthen horizontal broad sectional dimension, increases materials, thereby cause complete machine heaviness, cost to strengthen, safety performance descends, and installs and shifts and the difficulty of manipulating and become.
Summary of the invention
It is a kind of strong from heavy and light, load-carrying capacity that the purpose of this utility model is to provide, and can realize many fulcrums lifting machine of big span lift heavy.
Many fulcrums lifting machine in order to achieve the above object of the present utility model comprises body of the tower, crossbeam and fixed support; Crossbeam one end bearing is on body of the tower, and the other end is supported on fixed support and links to each other; Crossbeam between described body of the tower and fixed support is also supporting travel(l)ing rest.
Many fulcrums of the utility model lifting machine compared with prior art has following advantage: because the crossbeam between body of the tower and fixed support is supported with travel(l)ing rest, make crossbeam segmentation to lift by crane and mobile material, the segmentation of crossbeam is used on the one hand, shortened the actual stride of crossbeam greatly, section of beam size and materials are reduced, self alleviates, and the fitting operation of lifting machine also becomes more convenient, and usage safety performance greatly improves; On the other hand, the section on crossbeam, the section lifting of jointing type are mutually transferred weight, make the use span of lifting machinery obtain expanding, thereby the complete machine span is largely increased, and don't increase the complete machine deadweight.
Description of drawings
The utility model will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of a kind of implementation method of many fulcrums of the utility model lifting machine.
The specific embodiment
Many fulcrums lifting machine shown in Figure 1 comprises body of the tower 2, crossbeam 5, fixed support 7, body of the tower 2 mounting supports are on underframe 1, fixed support 7 is supported on the body of wall 8 (building), crossbeam 5 between body of the tower 2 and fixed support 7 is supporting travel(l)ing rest 6, equally, travel(l)ing rest 6 also is supported on the body of wall 8, lifting is housed on the crossbeam 5 transfers dolly 4, and lifting is transferred dolly 4 and is used to lift by crane material 3.
During use, with crossbeam 5 one end mounting supports on body of the tower 2, the other end then is installed on the fixed support 7, travel(l)ing rest 6 is also being supported in the appropriate location of crossbeam 5 between body of the tower 2 and fixed support 7, transfer dolly 4 by the lifting on the crossbeam 5 building material 3 is lifted by crane and be transferred to the top of building relevant position, this moment, body of the tower 2 and travel(l)ing rest 6 played the supporting role to crossbeam 5,7 not load-carryings of fixed support.The needs that transport according to material 3, the crossbeam relevant position can be moved and be supported on to travel(l)ing rest 6 to body of the tower 2, lift by crane and transfer material 3 again, this moment, travel(l)ing rest 6 and 7 pairs of crossbeams 5 of fixed support play supporting role, and body of the tower 2 not load-carryings, whole lifting is transferred material and is adopted segmentation lifting method of shipment, and the actual load-carrying span of crossbeam diminishes, and that the complete machine span can become is bigger.In order conveniently to regulate height, make stressed balanced and reasonable more, travel(l)ing rest adopts the adjustable structure commonly used that can regulate height; In order to adapt to the needs of differing heights lifting and transfer convenient transportation, body of the tower adopts telescopic tower simultaneously.According to the far and near needs of building material in top of building handover distance, the length of cross bearer can design two, three even more a plurality of travel(l)ing rest at this moment greatly, thereby realizes big span lifting handover material.
