2 guide rail 411, slide block 410 can be slided up and down in guide rail 411, and lever piece 41 is hinged on guide rail 411, the lever piece 41 1
The connection unit at end is anti-fall hook.In normal operating conditions upper end of slide block face tight against the lower end of lever piece 41, protect lever piece 41
Vertical poised state is held, and drive division is contradicted with connecting portion and be connected, so drive platform together to move with hydraulic jack 32,
Referring to Fig. 8.Once and there is fall condition, slide block 410 does free falling campaign, will conflict of the disengagement to the lower end of lever piece 41,
The side of guide rail gantry 1 under self-gravity action of lever piece 41 rotates, and above-mentioned bonding state is produced, referring to Fig. 7.
One preferred drive division is that drive division is the floating frame 43 for being provided with joist 44 with the design structure of connecting portion, even
Socket part is bottom lifting frame 42, and hydraulic jack 32 is fixed in floating frame 43, and floating frame 43 freely up and down can be arranged slidably
In lifting frame 42, such as Fig. 6.With reference to the drive division and connecting portion of the preferred structure, and anti-fall hook and cross bar are separately positioned on
On lever piece one end and guide rail bracket, there is the lever piece of anti-fall hook and with some vertically uniform horizontal strokes so as to form one end
The leading truck 1 of bar 11.In normal operating conditions, the joist upwards of floating frame 43 offsets with lever piece lower end, keeps lever piece
Vertical state, such as Fig. 3.When occurring when falling, floating frame free-falling, joist disengages the conflict to lever piece lower end, in deadweight
The lower guide rail gantry side of power effect rotates, and the anti-fall hook 4 in lever piece one end is colluded with a cross bar of leading truck respective heights, and is made
Unit first, second is in bonding state, prevents to drive platform to fall, and keeps the height and position that its is current, such as Fig. 4.
Further in conjunction with the drive division with above-mentioned preferred structure and connecting portion, and some carrying hooks 49 are vertically equal
Cloth is connected on described straight-bar so as to form one end on leading truck, by horizontal support bar 48 by a Y-shaped bracing frame
It is provided with the lever piece of horizontal support bar 48, such as Fig. 5.When occurring when falling, floating frame free-falling, joist is disengaged under lever piece
The conflict at end, guide rail gantry side rotates under self-gravity action, and the horizontal support bar 48 of lever piece one end is colluded with leading truck
On one carrying hook 49 of respective heights, Unit first, second is in bonding state, so as to prevent to drive platform to fall, keeps it
Current height and position, referring to Fig. 6.
In order to ensure that climbing platforms can be firmly held on present level position, especially when moving down, one
Preferred technical scheme is：Using unloading connector, the first embodiment for unloading connector is mutually to fit with above-mentioned cross bar 11
The unloading hook 45 matched somebody with somebody, such as Fig. 9, Figure 10, unloading hook 45 is hinged on lifting frame 42, and the center of gravity of unloading hook 45 is located at and is hinged
The top of point, and location-plate 46, location-plate 46 and unloading hook coupler body are welded with the unloading hook 45 at least lifting frame 42 of side
On be respectively equipped with corresponding location hole 47, unloading hook 45 and location-plate 46 by the grafting alignment pin in location hole 47 (in figure not
Draw) realize unloading the locking of hook 45, referring to Fig. 9.When alignment pin is extracted, unloading hook 45 is articulated under gravity guide rail
On cross bar 11 on frame 1, with the height and position for keeping lifting frame current, referring to Figure 10.
The another embodiment of unloading connector be the discharge arm corresponding with above-mentioned carrying hook 49 (not shown in figure,
Its structure is close to horizontal support bar 48, will not be described here).
