Description
Technical field
A kind of crane balance weight of the present invention, more particularly to a kind of crane packaged type balanced controls.
Background technology
Such as Fig. 1, crane is a kind of crane gear, by car body 100, arm 101, turntable 102, balance weight 103 and bottom
The grade of disk platform 104 part is constituted, and arm 101 and balance weight 103 are equipped with its intermediate station 102, and arm 101 is located at turntable 102
Front, balance weight 103 be located at arm 101 rear.
To increase the working range of crane, lift crane purposes, the general length of arm 101 is longer, the center of gravity of arm 101
And the centre of gyration of lift heavy thing centroidal distance turntable 102 is farther out, can form larger moment of flexure, the moment of flexure can form one kind and promote chassis
The trend that platform 104 is tumbled, to ensure the stability of chassis platform 104, can be designed with balance weight 103 at the rear of turntable 102,
The balance weight 103 has certain distance apart from the centre of gyration of turntable 102, so balance weight 103 can also form certain moment of flexure, this is curved
Square direction and the moment of flexure of the formation of arm 101 are in opposite direction, can reduce moment of flexure of the whole turntable 102 to chassis platform 104, reduce
The trend of tumbling of chassis platform 104, keeps chassis platform stable.
Existing crane balance is fixed with two kinds again：
1st, balance weight 102 is directly anchored on turntable 102 by bolt 105, and balance weight 102 cannot move regulation, such as Fig. 1 a.
2nd, it is furnished with slideway 106 in balance weight 102, balance weight 102 is assemblied in the afterbody of turntable 102 by slideway 106, balances
Forward and backward bolt fixing hole is designed with the slideway for weighing 102, balance weight is fixed on anterior position by bolt 107 during transport condition；
In crane long distance work, dismountable fixing bolt promotes balance weight to be slid backward along slideway by oil cylinder 108, slides
Balance weight is fixed by fixing bolt again after to rear position, balance weight moving process during traveling is on the contrary, with reference to Fig. 1 b.
Above two fixed form, in the presence of following defect：
1st, balance weight is irremovable, and the moment of flexure that balance is reformed is fixed, in crane long distance work, and arm side's moment of flexure can be by
Cumulative to add, then arm and the resultant bending moment of balance weight can become big, influence chassis platform stabilization, and transaction capabilities are restricted.
Although the 2, balance weight can backward slide along slideway, because of the weight size limitation of turntable length balance, balance weight sliding
Apart from limited, balance weight sliding tailheaviness no more than turntable least significant end, therefore this kind of shifting balance weight displacement is smaller, such as
Fig. 2.
