Ground lifting.
And then, lift appliance 10 includes: the compensation hoist cable 6 being connected with the bottom of lift car 4 and counterweight 5；It is arranged in benefit
Repay the compensating sheave 7 of hoist cable 6 bottom；The restraint device 8 of position limitation is carried out in order to make compensating sheave 7 not upspring；With work as
Detect that the rising or falling speed of car 4 makes the emergency braking device 9 of car 4 emergent stopping when having exceeded setting.
Then, with reference to Fig. 2, the structure for restraint device 8 illustrates.As in figure 2 it is shown, restraint device 8 mainly has
Casing 8c, voussoir 8d, roller 8e, spring body 8f and bolt 8g.
Casing 8c is quilt in the way of can moving up and down along the compensation guide rail 8a erecting setting near compensating sheave 7
Supporting.It addition, casing 8c has relative with compensating guide rail 8a and goes inclined plane 8b gradually expanded upward.
Voussoir 8d is arranged in the gap compensating guide rail 8a with inclined plane 8b of casing 8c, can rub with compensating guide rail 8a
In conjunction with mode configure.Roller 8e is clamped by inclined plane 8b of casing 8c and the apparent surface of voussoir 8d, and in inclined plane 8b
