Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
According to the method for adjusting the balance of the lifting appliance, disclosed by the invention, as shown in figures 1-2, the method is that a steel frame 2 capable of moving along the direction of a main beam 1 is arranged on the main beam 1 of the lifting appliance, and a lifting lug 3 is arranged at the top of the steel frame 2; when the lifting appliance is unbalanced, the steel frame 2 moves along the main beam 1 to the direction of heavier weight to restore the balance of the lifting appliance. The moving of the steel frame 2 is driven by the roller 5, the roller 5 is in close contact with the main beam 1, the roller 5 is connected with the hand wheel 8 through the wheel shaft 6, the roller 5 is driven to rotate by shaking the hand wheel 8, and the roller 5 and the top surface of the main beam 1 generate friction force to drive the steel frame 2 to move along the length direction of the main beam 1. After the steel frame 2 moves to a proper position of the main beam 1, the position of the steel frame 2 is fixed through a locking bolt 9 arranged at the top of the steel frame 2. When the position of the steel frame 2 is fixed, the short rack 10 on the top surface of the bottom plate of the steel frame 2 is meshed with the long rack 12 on the bottom surface of the main beam 1, so that the steel frame 2 and the main beam 1 are prevented from displacing when heavy objects are hoisted. The short rack 10 both sides of the bottom frame top surface of steel frame 2 are equipped with shell fragment 11 respectively, and when locking bolt 9 loosened, through shell fragment 11 with the separation of the long rack 12 on the short rack 10 on the steel frame 2 and the girder 1, do not influence normal regulation.
The device for adjusting the balance of the lifting appliance of the invention used for the method comprises a steel frame 2 sleeved on a main beam 1, as shown in figure 3; the top surface of the steel frame 2 is provided with a lifting lug 3, and the lifting lug 3 is provided with a lifting hole 4; a pair of rollers 5 are arranged at the upper parts of the two inner sides of the steel frame 2; the roller 5 is respectively connected with the steel frame 2 and the supporting plate 7 through a wheel shaft 6; one wheel shaft 6 passes through the steel frame 2 and is connected with a hand wheel 8. Two ends of the steel frame 2 are provided with a group of transmission mechanisms consisting of rollers 5, wheel shafts 6 and hand wheels 8. The top surface of the steel frame 2 at the corresponding position of the transmission mechanism is provided with a locking bolt 9; the locking bolt 9 vertically penetrates through the top plate of the steel frame 2. The middle of the top surface of the bottom plate of the steel frame 2 is provided with a short rack 10; spring plates 11 are respectively arranged at two sides of the short rack 10.
