Specific embodiment:
Mobile jib 7 is suspended in stair gap 24 by the hawser 4 of two cranes, and the length of mobile jib 7 is slightly longer than story height,
The pedal 14 and handle 8 that can be dug and be laid flat are hinged on mobile jib 7.
Two cranes are separately fixed on corridor both sides wall 5, and for main crane 1 on floor one side, secondary crane 2 is flat in turnover
On one side, two fixed pulleys 3 are mounted on the position that 24 both ends 21 of stair gap are equivalent on Roofing slab to platform, and two crane lines 4 divide
Not Jing Guo fixed pulley 3 downwards, two 4 ends of hawser tie up to the top of mobile jib 7 simultaneously, in this way, control the fortune of two cranes respectively
Turn, mobile jib 7 just can obliquely move upward or downward along pedestrian stairway.It such as allows and two cranes while operating, mobile jib 7 is just
It can be in stair gap 24 above and below straight line.
Pedal 14 be it is hinged by the pedal shaft 23 of 7 lower part of pedal-rod 19 and main sunpender, torsional spring is housed on pedal shaft 23
22 so that pedal 14 can be dug automatically when people leaves, and pedal shaft 23 and 7 junction of mobile jib are also welded with buting iron 20, and pedal 14 is put
Usually buting iron 20 can block pedal-rod 19 and so that pedal 14 is maintained at horizontal position and be subjected to the weight of human body.
The handle axle 17 at 7 middle part of handle 8 and mobile jib is hinged, and handle 8 is trisquare shape, makes all to be convenient for holding when stair activity.
Pedal 14 and handle 8 are all around each one, and respectively position as the front-rear position in mobile jib 7 makes up and down
Stair are all very convenient.
Digging and being laid flat for pedal-rod 19 and handle 8 is linkage, and control handle 8 can be used to be laid flat pedal 14,
Also handle 8 can be driven to dig together when pedal 14 is dug automatically, their side is all welded with ear and climbs 16 thus, and pedal-rod ear is climbed
And handle ear climb between it is hinged with connecting rod 18, the height that ear climbs 16 makes connecting rod 18 and its hinge joint deviate from pedal-rod 19 and handle
The spindle central line of hand 8 also avoids movement dead when handle 8 and pedal-rod 19 being made to link by connecting rod 18.Make
This hinge joint in shaft horizontal line each 45 degree of angle swinging up and down, this be most steerable swing angle pedal-rod 19 with
The local and handle 8 of parallel 10 contact of band iron guide rail is fitted with idler wheel 15 in the place contacted with balustrade 6, so that operation
Steadily, friction is reduced.
Two parallel band iron guide rails 10 identical with stair gradient are installed, and remove this in the lower part of stairway handrail 9
Local railing section between two band irons forms a parallel gap 11 identical with stair gradient, makes pedal-rod 19 can be with
The railing 12 that but 6 both ends of balustrade are run in this gap not only still needs to keep complete, in addition it is also necessary to reinforce, to keep stair
Handrail 6 consolidates.In addition it to be then extended to slightly larger than pedal 14 close to the gap 13 at both ends railing 12, so that pedal 14 can be with
It digs herein.
Illustrate use process of the invention below:
First say building:
People and mobile jib 7 are in bottom or certain floor, will first press under handle 8, and handle 8 is driven by connecting rod 18 and turned under pedal 14
At level, people can stand upper pedal 14, open the button switch startup power supply at handle 8, and main crane 1 first moves, and rotate forward, and draw mobile jib
7 rise i.e. parking after a lattice step, move, rotate forward after secondary crane 2, its oblique pulling mobile jib 7 of hawser 4 tilts uplink, pedal-rod
19 and handle 8 on idler wheel 15 rolled respectively along balustrade 6 and band iron guide rail 10, guide mobile jib 7 and people to tilt along stair
It is equal with turnover platform to go upward to pedal 14, parking, people takes a step to turnover platform, automatic turning under the action of torsional spring 22 of pedal 14
It rises, while handle 8 being driven also to dig, people and mobile jib 7 are in turnover platform, continue upstairs, to press the handle 8 of another side, repeat
Above-mentioned steps are only changed to move after secondary crane 2 first moves main crane 1, until reaching next level, continue to repeat the above steps straight
To arrival purpose floor;
Besides downstairs:
Mobile jib 7 is in certain floor, will first press under handle 8, and handle 8 is driven by connecting rod 18 and translates into level, people under pedal 14
Can stand upper pedal 14, open the button switch startup power supply at handle 8, and main crane 1 first moves, and invert, its hawser 4 is oblique to be put
Mobile jib 7 tilts downlink, and the idler wheel 15 on pedal-rod 19 and handle 8 is rolled along balustrade 6 and band iron guide rail 10 respectively, guidance
Mobile jib 7 and people are along stair inclination downlink, and secondary crane slightly petty action during this, reversion, it is small that its hawser 4 puts mobile jib 7 one
Section, coming downwards to mobile jib 7 can just, pedal 14 is equal with turnover platform, and parking, people takes a step to turnover platform, and pedal 14 is in torsional spring
It is dug under the action of 22, while handle 8 being driven also to dig, people and mobile jib 7 are in turnover platform, continue to go downstairs, and press another
The handle 8 in face, repeats the above steps, and only secondary crane 2 first moves, and inverts, the slightly petty action after of main crane 1, reversion, until reaching
Lower first floor continues to repeat the above steps until reaching bottom or purpose floor;
Calling empty wagons meets people:
When empty wagons, pedal 14 and handle 8 are in tip-up state, and at this time by the push button being fixed on wall, usual situation is at this time
Mobile jib be in floor one end, secondary crane 2 will first slightly petty action, rotate forward, if special circumstances mobile jib is in turnover platform one end, then master hangs
Vehicle will first slightly petty action, rotate forward, two kinds of situations are mobile jib 7 to be first pulled to 24 middle section of stair gap, then chief and vice crane moves together, general
Mobile jib 7 is drawn or puts to demand floor, the slightly petty action again of secondary crane 2, and reversion puts mobile jib 7 to the floor platform in stair gap 24
End 21 waits work.
