Detailed Description
The invention will be further explained below with reference to the drawings and examples.
As shown in fig. 1 to 4, the lifting beam for the monorail crane comprises two groups of lifting beam bodies 1, the lifting beam bodies 1 are connected to the monorail crane 3 in a sliding mode through traveling trolleys 2, each traveling trolley 2 comprises an I-shaped traveling frame body 2-1, as shown in fig. 1, 3 and 4, two pairs of traveling wheels 2-2 are arranged on the inner side of one of the traveling frame bodies 2-1, the paired traveling wheels 2-2 are respectively installed on two sides of the monorail crane 3, the traveling frame body 2-1 at the lower portion of each traveling wheel 2-2 is movably connected with the lifting beam body 1, and a connecting seat is installed above the lifting beam body 1 and used for being movably connected with the traveling frame body 2-1 through bolts. The two sides of the walking frame body 2-1 are provided with openings 2-3, wheel shafts of the walking wheels 2-2 are clamped into the openings 2-3, the walking frame body also comprises a connecting plate 2-4, the walking wheels 2-2 positioned on the same side of the walking frame body 2-1 are fastened through bolts and the connecting plate 2-4, the wheel shafts of the walking wheels 2-2 positioned on the same side of the walking frame body 2-1 are all sleeved on the connecting plate 2-4, and then nuts sleeved on the wheel shafts are screwed, so that the walking wheels 2-2 can be fixed on the walking frame body 2-1. The gap 2-3 is convenient for the mounting and dismounting of the walking wheel 2-2.
A motor 4 is arranged at one end of the lifting beam body 1, the motor 4 is in transmission connection with a speed reducer 5, and a coaxial ratchet friction plate type one-way brake and a driving chain wheel are arranged in the speed reducer 5; the lifting beam body 1 is provided with a hook 6 and a fixed plate 7 with a plurality of groups of U-shaped grooves, the fixed plate 7 is provided with a fixed chain wheel 8, a movable chain wheel 9 and a chain tail end fixer 10, one end of a chain 11 is hooked on the hook 6, and the other end of the chain 11 sequentially passes through a driving chain wheel, the fixed chain wheel 8, the movable chain wheel 9 and a sliding chain wheel on a lifting hook 12 and then is fixed with the chain tail end fixer 10; the two ends of the lifting beam body 1 are respectively provided with a connecting support 15, and the connecting rod 13 is hinged with the connecting supports 15 of the two groups of lifting beam bodies 1 to hinge the two groups of lifting beam bodies 1 into a whole; the lifting distance between the lifting hooks 12 on the two groups of lifting beam bodies 1 is adjusted by adjusting the fixed positions of the movable chain wheel 9 and the chain tail end fixator 10 on the fixed plate 7, namely the movable chain wheel 9 and the chain tail end fixator 10 are adjusted to rotate different U-shaped grooves on the fixed plate 7 for installation.
As an improvement of this embodiment, the lifting beam body 1 is further provided with a riding wheel 14, the riding wheel 14 is located between the speed reducer 5 and the hook 6, the chain 11 is wound around the riding wheel 14, and the riding wheel 14 can avoid the chain 11 from being excessively long and dragged.
The hoisting beam is dragged by the diesel monorail crane or the pneumatic monorail crane to run on the monorail crane. When the heavy object is lifted, the motor rotates forwards to drive the speed reducer to operate, and then the ratchet friction plate type one-way brake drives the driving chain wheel to lift the heavy object. When the motor rotates reversely, the heavy object can be dropped. When the motor stops running, the ratchet friction plate type one-way brake can automatically brake under the action of load. The pawl is meshed with the ratchet wheel under the action of the spring, so that the safe operation of the brake is ensured. The movable chain wheel and the chain tail end fixer are adjusted according to the size of a lifted object, and then the distance between the two lifting hooks is adjusted, so that the two lifting hooks can lift the lifted object more stably. When the motor rotates reversely, the chain is driven to descend together under the action of the gravity of the lifting hook; when the motor rotates forwards, the redundant chain between the supporting wheel and the speed reducer is normally retracted by the gravity of the chain between the supporting wheel and the hook, and if the redundant chain between the supporting wheel and the speed reducer cannot be retracted by the gravity of the chain between the supporting wheel and the hook due to the fact that the hook descends too much, the redundant chain between the supporting wheel and the speed reducer can be retracted through manual assistance.
