Description

A kind of pedal type escalator
Technical field
The present invention relates to a kind of pedal type escalator, this escalator is specially adapted to both with or without elevator tier building.Conveniently can go on a journey inconvenient resident simultaneously, and maximum is cost-saving.
Background technology
Architectural design new criteria specifies more than four layers new building stair case lift-mountings, is badly in need of transformation between existing more than four layers architectural stairs.Express lift is applicable to skyscraper, and the number of plies is more high more economical.Escalator is applicable to the public building that the stream of people concentrates.Therefore for a large amount of existing multilayer without elevator residential building, express lift and escalator are all inapplicable, and the improvement project of house ornamentation elevator is difficult.Need to expend huge fund on the one hand, need in the new space of developing on the one hand, the space erection elevator main body of general building external wall, makes the Retrofit of Elevator engineering of close-packed old community be difficult to realize like this.
Summary of the invention
The technical problem to be solved in the present invention is based on existing staircase design, proposes a kind of high low type pedal type elevator, namely adopts horizontal direction to walk by people oneself, vertically helps lifting by pedal, bear gravity, have the dual-use function of stair and elevator.No matter newly-built tier building or existing tier building all must not take building area, keep the function of original stair walking, can have again the elevator functions of lifting.
For solving the problems of the technologies described above, pedal type escalator of the present invention comprises lifting pedal 3 and controls the autonomous cruise speed system of described lifting pedal operation.This lifting pedal, panel of marking time, base plate, be placed in die mould bearing plate, the Motorized lift device of marking time between panel and base plate, backplate.Described Motorized lift device is located in die mould bearing plate gap, and upwards, drive panel of marking time to rise to setting height vertically upward to promote die mould bearing plate, described Active foot plate is located on former stair step step the power direction of Motorized lift device.
The panel of this Active foot plate, base plate, shoulder guard and die mould bearing plate can be steel plate.Motorized lift device can be electric hydraulic lifting jack.
This pedal type escalator also comprises initial pedal and stops pedal, in pattern upstairs, described initial pedal be located at former stair upstairs before landing on, described initial pedal transmit upstairs signal to autonomous cruise speed system.In downstairs pattern, described termination pedal be located at former stair upstairs after landing on, described termination pedal transmission downstairs signal to autonomous cruise speed system.
The operation of this pedal type escalator comprise the steps: (one) stop pedal or initial pedal by upstairs or the actuation signal of going downstairs be transferred to autonomous cruise speed system; (2) autonomous cruise speed system opens pattern or downstairs pattern upstairs, and described pattern upstairs or downstairs pattern comprise wheelchair pattern and Walking Mode respectively; (3) lifting pedal runs successively; (4), upstairs or after downstairs terminating, automatic controlling system lifting pedal playbacks.Autonomous cruise speed system judges whether according to the changes in weight before and after on lifting pedal the operation carrying out next lifting pedal.
Under the wheelchair pattern of pattern upstairs, lifting pedal rises successively according to the order of step upstairs of stair, be implemented as: wheelchair enters initial pedal, autonomous cruise speed system starts wheelchair program upstairs, wheelchair continues to move ahead, enter the first lifting pedal, changes in weight reaches autonomous cruise speed system, autonomous cruise speed system sends next step and promotes instruction, initial pedal and the first lifting pedal drive wheelchair upwards to rise, first lifting pedal docks with the second lifting pedal level, now initial pedal, first lifting pedal and the second lifting pedal are in same level, wheelchair advances, enter the second lifting pedal, autonomous cruise speed system sends next step and promotes instruction, second lifting pedal and the first lifting pedal drive wheelchair upwards to rise, second lifting pedal docks with the 3rd lifting pedal level, now the 3rd lifting pedal, first lifting pedal and the second lifting pedal are in same level, wheelchair advances, enter the 3rd lifting pedal, follow-up lifting pedal continues to run in the manner described above, until wheelchair is advanced to stop pedal 1, terminate wheelchair instruction upstairs, all lifting pedals return initial position, terminate upstairs.
Under wheelchair pattern under the pattern of going downstairs, lifting pedal is all promoted to wheelchair and goes downstairs position, then decline successively according to the order of step downstairs of stair, be implemented as: wheelchair enters termination pedal, autonomous cruise speed system starts wheelchair and to go downstairs program, and whole lifting pedal is promoted to wheelchair and goes downstairs position.Wheelchair advances, after wheelchair enters the first lifting pedal and the second lifting pedal, weight data is transferred to autonomous cruise speed system by the second and first lifting pedal, autonomous cruise speed system sends next step instruction, first and second lifting pedals drive wheelchair to decline, second lifting pedal docks with the 3rd lifting pedal level, now the first lifting pedal, second lifting pedal and the 3rd lifting pedal are in same level, wheelchair continues to advance, enter the 3rd lifting pedal, follow-up lifting pedal continues to run in the manner described above, until wheelchair is advanced to termination pedal, autonomous cruise speed system starts wheelchair and to go downstairs program, afterbody lifting pedal and termination pedal drive wheelchair to decline, return initial position, terminate wheelchair instruction upstairs, downstairs terminate.
the invention has the beneficial effects as follows
Pedal type escalator of the present invention is simple and reasonable, has various modes, easy to use.
1. this escalator operating method is the demand that elevator set up by existing multi-storey building, provides optimal selection.Solve the drawback that general elevator is only applicable to skyscraper.
2. the no matter newly-built tier building of this escalator operating method or existing tier building all must not take building area, keep the function of original stair walking, can have again the elevator functions of lifting.
