And deviation data is provided to control system while being repaired.Equally, may also set up on rear sedan-chair frame 17 and preceding 18 top beam of sedan-chair frame
Traction steel-cable 4 wanders off correcting device.
The car suspension fag end 13 and set that 4 both ends of traction steel-cable of the present embodiment are provided in respectively on fag end girder steel 3
Put the counterweight suspension fag end 1 on counterweight girder steel 2.Car hangs fag end and counterweight suspension strop head position is equipped with pulling force and counts dress
It puts.The routine work data of traction steel-cable 4 are recorded by pulling force counting device.
By front and rear secondary sedan-chair frame suspension 15 load of car, and single traction steel-cable 4 is made to be formed wherein on one group of pair sedan-chair frame
Suspension number of share of stock for 4 strands, the suspension number of share of stock formed on another group of pair sedan-chair frame is 2 strands.
Specific hanging method is as follows：Traction sheave of the one end of traction steel-cable 4 through traction host 10, to 15 side of car
Preceding 18 one crosshead sheave 11 in top of sedan-chair frame passes through, then upwards on two car diversion sheaves 12 being installed on host girder steel 7
Side, then downward to the another crosshead sheave 11 of preceding sedan-chair frame 18；Again back towards on before and after being installed on guiding girder steel 16
Directive wheel 14, two crosshead sheaves 11 after two front and rear directive wheels 14 down around after above sedan-chair frame 17, until connecting upwards
It is connected to and is fixed around fag end girder steel 3 and car suspension fag end 13.Traction of the other end of traction steel-cable 4 through traction host 10
Wheel after leading to the wheel group being made of three counterweight diversion sheaves 6 and two pieces counterweight computer room diversion sheave 8 by directive wheel 9, is connected to pair
On counterweight suspension fag end 1 on weight girder steel 2.
Under the conditions of equal trctive power：Wiring hangs ratio 1:When 1, elevator loading amount is 1500kg, is hanged using wiring
Hang ratio 4:1 design, elevator loading amount are 6000kg, and the technical program breaches conventional wiring suspension ratio 4:The following elevator such as 1 carries
The limitation of weight, particularly heavy－duty object delivery requirement, elevator loading amount increase up to 7000kg, 8000kg, 9000kg etc.
Add 50% traction lifting capacity, be more suitable for the requirement of heavy－duty carriage lift object.
For in terms of the car hanging load stability, wiring suspension ratio 4:1 elevator, car suspension design are car
Medium position load, car load are concentrated load, when car cab depth is larger, in the case of heavy－duty object is transported, are being filled
Unbalance loading, i.e. run-off the straight before and after elevator bodies easily occur for the process car cab of unloading, and enabling probability of malfunction is caused to increase.And the present embodiment sedan-chair
Compartment suspension is the forward and backward sedan-chair frame of car, and stress balance is stablized, and hitch point arrangement is more reasonable, under various working conditions, will not
Generation unbalance loading load makes elevator operation relatively reliable.
Above-described embodiment is the explanation to the utility model, is not the restriction to the utility model, as computer room carries girder steel
Sphere of movements for the elephants shape structure etc. is designed as, structure after any simple transformation to the utility model etc. belongs to the utility model
Protection domain.
