Specific introduce is made to the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 to Figure 3, a kind of elevator shaft platform 100, including：Landing slab 101, connection for people's standing at work
The movable suspension pendant 102 of the hook of crane or tower crane, motor 103, the starting switch 104 for starting motor 103, control motor 103
Reversing switch 105, gear 106, rack 107, hollow tube 108, telescopic rod 109 and the supporting rod 110 of commutation；Hollow tube 108 is solid
Determine to landing slab 101；The both ends of supporting rod 110 are individually secured to landing slab 101 and hollow tube 108；Movable suspension pendant 102 slides
It is connected to landing slab 101；Movable suspension pendant 102 has the first position of triggering starting switch 104 and is detached from and starting switch 104
The second position of contact；Movable suspension pendant 102 slides between the first position and the second position relative to landing slab 101；Start
Switch 104 is fixed to landing slab 101；Motor 103 drives gear 106 to rotate；Gear 106 and rack 107 engage；Rack 107 is solid
Determine to telescopic rod 109；109 part of telescopic rod is located in hollow tube 108 and is slided relative to hollow tube 108.
Further, hollow tube 108 favours landing slab 101.
Further, supporting rod 110 favours landing slab 101.
Further, hollow tube 108 is more than or equal to 30 degree with 101 angle of landing slab and is less than or equal to 60 degree.
Further, elevator shaft platform 100 further includes supporting rack 111；Supporting rack 111 is fixed under landing slab 101
Portion；Motor 103 is fixed to supporting rack 111；Gear 106 is rotatablely connected to supporting rack 111.
Further, motor 103 is rotated by 112 transmission belt moving gear 106 of belt.
Further, elevator shaft platform 100 further includes the power supply 113 powered for motor 103；Power supply 113 is fixed to branch

Operation principle：When elevator shaft platform 100 needs lifting, two hooks of crane or tower crane are caught on into movable suspension
Pendant 102 and fixed suspender 114, pull then up.It at this time can be relative to landing slab 101 in first position and second
The movable suspension pendant 102 slided between setting is by the pulling force of crane or the hook of tower crane by second position upward sliding to first
It sets.Movable suspension pendant 102 starts in first position started by press switch 104 to control motor 103.Motor 103 is driven forward
Belt 112 with moving gear 106 to rotate clockwise.Gear 106 drives the rack 107 engaged with gear 106 to be stretched to drive
