Shown in Fig. 4 a, the plan structure of lifting frames at different levels is square or rectangle.In the two opposite sides of one-level lifting frame 31 one group of elevating chain group 93 is set respectively, every group comprises two pairs of elevating chain groups, around the home on the elevating chain steering base 91 at the crossbeam 9a two ends of being fixed in bottom fixing frame 9; In the two opposite sides of two grade of ascend and descend frame 32 one group of elevating chain group 94 is set respectively, every group comprises two pairs of elevating chain groups, around the home on the elevating chain steering base 92 at the crossbeam 31a two ends of being fixed in one-level lifting frame 31; The fixing hoist cylinder 34 in the bottom of two grade of ascend and descend frame 32, piston rod 34 are placed in and carry out flexiblely up and down in the hoist cylinder 34, and its top connects the top of three grades of lifting frames 33, and lifting platform 10 is settled at the top of lifting frame 33.
As shown in Figure 5, the inboard chain of elevating chain group 93 links to each other with the crossbeam 31a of one-level lifting frame 31 bottoms by connection set 95.Fig. 6 shows the zoomed-in view of connection set 95, establish fitting seat 31a ' on the crossbeam 31a, connection set 95 comprises the connecting base 953 that links to each other by bolt with fitting seat 31a ', connecting base 953 cross sections take the shape of the letter U, the upper end of elevating chain group 93 is fixed on the top of link 954, the lower end is fixed on the bottom of link 954, and link 954 is clamped in the U-shaped mouth of connecting base 953 by bolt 934.
Shown in Fig. 6 a, the lower end of elevating chain group 93 or the carrier bar of upper end insert in the carrier bar fixed hole seat 951, pass the hole and the carrier bar fixed hole seat 951 of carrier bar by making latch 955, and elevating chain group 93 and link 954 are fixed into one.
Shown in Fig. 5,17, on the top cross-bar 9a of bottom fixing frame 9, settle elevating chain group steering base 91, shown in Fig. 7 a, fixed base 914 is set on the crossbeam 9a, elevating chain group steering base 91 is fixed on the fixed base 914 by bolt 913, elevating chain group steering base 91 bottoms are provided with sprocket bearing 911, be equipped with on it be used for elevating chain group 93 around the home turn to sprocket wheel 912.
As shown in Figure 5, on the drive sprocket 97a that also is wound on drive unit of elevating chain group, make elevating chain group 93 form a chain ring by sprocket wheel 912 and output sprocket 97a, when drive unit drive drive sprocket 97a turns clockwise, rise in the inboard of elevating chain group 93, the outside descends, and by being fixedly coupled the bottom that device 95 upwards spurs one-level lifting frame 31 with elevating chain group 93, one-level lifting frame 31 is risen.
With reference to Fig. 4, the mounting structure and mode and the working procedure that make the elevating chain group 94 that two grade of ascend and descend frame 32 hoists are described: an end of internal layer elevating chain group 94 is fixed on the fixed base 99a on bottom fixing frame 9 base cross members, the other end is walked around the sprocket wheel that turns on the interior elevating chain steering base 92 on the crossbeam 31a that is fixed on one-level lifting frame 31 tops, is fixed in the fixed base 99b on two grade of ascend and descend frame 32 base cross members.
When one-level lifting frame 31 rises under outer elevating chain group 93 drives, interior elevating chain group part between fixed base 99b and the internal layer elevating chain steering base 92 shortens gradually, and the interior elevating chain group part between fixed base 99a and the internal layer elevating chain steering base 92 prolongs gradually, rises by internal layer elevating chain group 94 pulling two grade of ascend and descend framves 32 thus.When one-level lifting frame 31 rose to the extreme higher position, internal layer elevating chain group 94 also drove two grade of ascend and descend frame 32 and arrives the extreme higher position.
