As depicted in figs. 1 and 2, in the present embodiment, the elevating platform assembly for weighing apparatus of mutually keeping tie includes：Hoistable platform 100, four
Lifter and four weighing apparatus 50,60,70 and 80 of mutually keeping tie.Four lifters are respectively 1# lifters 10,2# lifters 20,3# liters
Device 30 and 4# lifters 40 drop.
Four lifters are rectangular, are arranged on the lower section of hoistable platform 100.Lifter include fixed frame 11 (21,31,
41), actuator 12 (22,32,42) and crane 13 (23,33,43).Fixed frame is fixed in the horizontal plane or and other datum levels
On, the benchmark of the elevating platform assembly as weighing apparatus of mutually keeping tie, in bottom, relative to not moving.The fixing end of actuator is fixed on
The top of fixed frame, telescopic end are fixed on the lower section of crane.Hoistable platform 100 is fixed on the top of four cranes.Driving
Part is hydraulic cylinder or cylinder.
Certainly, the quantity of lifter increases or decreases, and distribution can be set according to actual needs, can also circumferentially be evenly distributed with
Setting.
Weighing apparatus of mutually keeping tie includes：Connecting rope 51 (61,71,81), lower fixed pulley 52 (62,72,82), conversion pulley 53 (63,
73rd, 83) and top sheave 54 (64,74,84).Connecting rope in the present embodiment is steel wire rope, naturally it is also possible to using other materials
Connecting rope is made.In each weighing apparatus of mutually keeping tie, fixed pulley under the lower section setting that connecting rope is connect with the lower end of crane, lifting
Frame to lower fixed pulley connecting rope in vertical state；The upper fixed pulley of top setting that connecting rope is connect with the upper end of crane,
The connecting rope of the supreme fixed pulley of crane is in vertical state.Convert the direction of 90 degree of pulley or 180 degree conversion connecting rope.
The lower fixed pulley 52 of mutual weighing apparatus 50 of keeping tie is arranged on the lower section of the crane 13 of 1# lifters, one end of connecting rope 51
The lower end of crane 13 is connected, vertically downward, around lower fixed pulley 52, using 90 degree of 53 bending of pulley of conversion vertically upward
Afterwards, further around the upper fixed pulley 54 crossed above the crane 23 for being arranged on 2# lifters, vertically downward finally, connection 2# lifters
The connection of a weighing apparatus of mutually keeping tie is realized in the upper end of crane 23.
Cycle connection successively, the connecting rope 61 for weighing apparatus 60 of mutually keeping tie, one end and the lower end of the crane 23 of 2# lifters connect
