Specific implementation mode:
Mobile jib 7 is suspended on by the hawser 4 of two cranes in stair gap 24, and the length of mobile jib 7 is slightly longer than story height, in master
The pedal 14 that can be dug and be laid flat and handle 8 are hinged on bar 7.
Two cranes are separately fixed on corridor both sides wall 5, and main crane 1 is on floor one side, and secondary crane 2 is in turnover platform one
Side, two fixed pulleys 3 are mounted on the position that 24 both ends 21 of stair gap are equivalent on Roofing slab, and two crane lines 4 pass through respectively
Cross fixed pulley 3 downwards, two 4 ends of hawser tie up to the top of mobile jib 7 simultaneously, control the operating of two cranes respectively in this way, main
Bar 7 just can obliquely move upward or downward along pedestrian stairway.It such as allows and two cranes while operating, mobile jib 7 just can also
Above and below 24 cathetus of stair gap.
Pedal 14 is hinged by the pedal shaft 23 of 7 lower part of pedal-rod 19 and main sunpender, on pedal shaft 23 equipped with torsional spring 22 with
Pedal 7 is set to be dug automatically when people leaves, pedal shaft 23 and 7 junction of mobile jib are also welded with buting iron 20, buting iron when pedal 7 is laid flat
20, which can block pedal-rod 19, makes pedal 14 be maintained at horizontal position and is 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 are respectively in the front and back position of mobile jib 7.Such position 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 for being laid flat pedal 14, step on
Also handle 8 can be driven to dig together when plate 7 is dug automatically, their side is all welded with ear and climbs 16 thus, and pedal-rod ear is climbed and handle
Hand ear is hinged with connecting rod 18 between climbing, and the height that ear climbs 16 makes connecting rod 18 and its hinge joint deviate from pedal-rod 19 and handle 8
Spindle central line, also avoid through connecting rod 18 come movement dead when handle 8 and pedal-rod 19 being made to link.Make this hinge
For contact in shaft horizontal line each 45 degree of angle swinging up and down, this is most steerable swing angle.
Pedal-rod 19 is all installed in the place and handle 8 contacted with parallel band iron 10 in the place contacted with balustrade 6
There is idler wheel 15, so that the reduction friction that operates steadily.
Two parallel band irons 10 identical with stair gradient are installed, and remove this two band irons in the lower part of stairway handrail 9
Between local railing section, formed a parallel gap 11 identical with stair gradient, allow pedal-rod 19 in this gap
Middle operation.But the railing 12 at 6 both ends of balustrade not only still needs to keep complete, it is also necessary to reinforce, to keep balustrade 6
It is firm.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 turn over herein
It rises.
Illustrate the use process of the present invention below:
First say building:
People and mobile jib 7 are in bottom or certain floor, will first be pressed under handle 8, and handle 8 is driven by connecting rod 18 and translates into water under pedal 14
Flat, people can stand upper pedal 14, open the button switch startup power supply at handle 8, main crane 1 first moves, and rotates forward, and draws on mobile jib 7
It stops after rising a lattice step, is moved after secondary crane 2, rotated forward, its 4 oblique pulling mobile jib 7 of hawser tilts uplink, 19 He of pedal-rod
Idler wheel 15 on handle 8 is rolled along balustrade 6 and band iron guide rail 10 respectively, and mobile jib 7 and people is guided to tilt uplink along stair
Equal with turnover platform to pedal 14, parking, people takes a step to turnover platform, and pedal 14 is dug automatically under the action of torsional spring 22,
Handle 8 is driven also to dig simultaneously, people and mobile jib 7 are in turnover platform, continue upstairs, to press the handle 8 of another side, repeat above-mentioned
Step is only changed to move after secondary crane 2 first moves main crane 1, until reaching next level, continues to repeat the above steps until arriving
Up to purpose floor.
Besides downstairs:
Mobile jib 7 is in certain floor, will first be pressed under handle 8, and handle 8 is driven by connecting rod 18 and translates into level, people under pedal 14
Pedal 14 on standing opens the button switch startup power supply at handle 8, and main crane 1 first moves, and inverts, its hawser 4 is oblique to put mobile jib
7 tilt 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, guides mobile jib 7
Downlink is tilted along stair with people, secondary crane slightly petty action during this, reversion, it is a bit of that its hawser 4 puts mobile jib 7, makes
Mobile jib 7 can just come downwards to pedal 14 with turnover platform it is equal, parking, people take a step to turnover platform, pedal 14 is in torsional spring 22
It is dug under effect, while handle 8 being driven also to dig, people and mobile jib 7 are in turnover platform, continue to go downstairs, and press the handle of another side
Hand 8, 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 next layer
Building 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, at this time by the push button being fixed on wall, normal conditions mobile jib at this time
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 main crane will
First slightly petty action rotates forward, and two kinds of situations are mobile jib 7 to be first pulled to 24 stage casing of stair gap, then chief and vice crane moves together, by mobile jib
7 draw or put to demand floor, the slightly petty action again of secondary crane 2, and reversion puts mobile jib 7 to the floor levels end in stair gap 24
21, wait for work.
