Abstract
The utility model discloses a lifting device for crane cross spreaders which is composed of a supporting frame (1), a pulley block, a rope reel drum (5), a rope (4), etc., wherein, the pulley block comprises a movable pulley (2) and a fixed pulley (3), the reel drum (5) can be controlled by hands or electricity. The reel drum (5) is driven to cause the crane cross spreader to be lifted to a scheduled position without manpower lift and help, which reduces labor intensity and improves work efficiency, and the utility model has the advantages of high safety and convenient operation.
Description
The utility model belongs to civilian construction lifting machinery technical field, relates in particular to the lifting machine crossbeam hoisting mechanism of being made up of bearing support and assembly pulley.
Building operations be unable to do without the material lifting machinery.At present, widely used tower lifting machinery in the civilian construction construction works, it is big to have lifting altitude, characteristics such as effective breadth is wide, but exist complex structure simultaneously again, trouble is installed, shift inconvenience, particularly its main stress spare crossbeam (jib) is a cantilever beam structures, and is stressed unreasonable, having a strong impact on complete machine overturning or slip resistance analysis performance.At the problems referred to above, Chinese patent application 97207351.5 discloses a kind of civilian construction hanging apparatus, this device passes through a branching bolster supporting on building with crossbeam (jib) cantilever end of tower lifting machine, makes crossbeam constitute a simple beam structure, and it is stressed reasonable to make, designs simplification, whole overturning or slip resistance analysis performance greatly improves, but this structure still need rely on manpower that crossbeam is lifted on the bearing support, and not only installation effort is time-consuming, labour intensity is big, and very dangerous.
It is a kind of easy to use, simple in structure that the purpose of this utility model is to provide, and can reduce the crossbeam lifting appliance of labour intensity effectively.
In order to achieve the above object, the technical solution of the utility model is: on the beam supporting frame that is set up on the building, assembly pulley is installed, this assembly pulley comprises fixed pulley and movable pulley, an end that connects the assembly pulley rope is wound on the reel, is connected with suspension hook on the movable pulley.The driving reel rotates, and just can crossbeam be risen to the precalculated position by the suspension hook on rope and the movable pulley.
After adopting such structure, owing on bearing support, be provided with assembly pulley, so as long as drive reel and drive suspension hook on the movable pulley by rope and fixed pulley, after the lifting machine crossbeam risen to the appropriate location, crossbeam can be fixed on the bearing support, take and need not to lift with manpower, not only simple in structure, and also easy to operate; Owing to the assembly pulley on the bearing support, can reach the purpose that reduces the reel driving moment, thereby more effectively reduce labour intensity again by the different winding methods of rope.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of specific embodiments of the utility model crossbeam lifting appliance.
Fig. 2 is the structural representation of the utility model crossbeam lifting appliance reel part shown in Figure 1.
Shown in Figure 1, the crossbeam lifting appliance comprises compositions such as bearing support 1, movable pulley 2, fixed pulley 3, rope 4 and reel 5.Bearing support 1 is a support body that is welded by section bar, top-supported at bearing support 1 has rotating fixed pulley 3, fixed pulley 3 is two pulleys of installing side by side, and reel 5 also is supported on the bearing support 1 by bolster 7, and bearing support 1 is installed on the top of building 12.The rope 4 that is wound on the reel 5 is connected with movable pulley 2 by fixed pulley 3, suspension hook 10 is housed on the movable pulley 2, suspension hook 10 is used for hook block crossbeam 11, rotating drum 5 can promote crossbeam 11 to the precalculated position by rope 4, after crossbeam 11 arrives the precalculated position, plug steady pin 13 and just make crossbeam 11 firmly be supported on the bearing support 1.
Fig. 2 is the structural representation of the reel part of embodiment shown in Figure 1, the ratchet 8 of reel 5, ratchet and pawl arrangement and wind 6 are fixed on the bolster 7, and be supported on the bearing support 1 by bolster 7, ratchet 9 in the ratchet and pawl arrangement stops reel to reverse arbitrarily by ratchet 8, ratchet 9 is installed on the bearing support 1, this structure both can promote crossbeam 11 and be positioned the optional position, dangerous and the destruction that can prevent crossbeam from freely descending again and take place, rotary handle crank 6 can drive reel 5 and rotate and winding rope 4.Certainly, more laborsaving, efficient for the lifting that makes crossbeam 11, also available motor drives bolster 7 and reel 5, and the conversion of this wind and motor all drops within the protection domain of the present utility model.
