Description
Technical field
The utility model relates to a kind of accessible climbing device, and specifically a kind of electric stair climbing car especially can be creeped in any gradient below 35 ° and advanced; Be applicable to the home for destitute, disabled person, logistics; The public place, places such as community, tourist attraction, mountain area belong to the creeper-traveler field.
Background technology
Climb the building equipment and technology at present both at home and abroad: the stair climbing jacking system in wheels formula, legged, crawler type, the specialized range.Though climbing building equipment, these all have advantage separately.But weak point is also arranged.
Wheels formula: use the number of steamboat can be divided into two wheels formulas, three wheels formulas and four-wheel group formula and many wheel level formulas in the wheels.The stairs climbing device of wheels formula stair climbing wheelchair is made up of several steamboats that are evenly distributed on " Y " shape or "+" font tie-rod.Each steamboat both can be around axis rotation separately, again can be along with tie-rod revolves round the sun around center shaft together.When level walking, each steamboat rotation, and during stair climbing, each steamboat revolves round the sun together, thus realize the function of stair climbing.Single-wheel group formula structural stability is relatively poor, in climbing the building process, needs the people and assists to guarantee the stable of center of gravity; Though and two-wheel group formula can realize independently climbing the building,, influenced its range of use because it is bulky and lay particular stress on.In advancing, use can produce certain effect of fearing at heart.
Legged: its stair climbing actuating unit is made up of hinge rod member mechanism.Earlier heavy burden is raised in the time of upstairs, level moves forward again, so repeats these two processes until having climbed a flight of stairs.The action that legged stair climbing device mimic human is climbed the building, outward appearance can be considered legged type robot, adopts the principle that many pedipulators alternately go up and down, supporting chair is climbed the building.Motion steadily was fit to the stair of different size when legged stair climbing device was climbed the building; But it is very high to the requirement of control, the operation more complicated, and motion amplitude is little when level walking, and is slow in one's movements.
Crawler type: the principle of stair climbing device is similar to crawler belt armored personnel carrier or tank; Its principle is simple, and technology is comparative maturity also, and the stair climbing wheelchair of caterpillar type mechanism is used more; It adopts the walking manner more more continuous than star-like wheel mechanism, and driving efficiency is than higher.In the stair activity process, the center of gravity of wheelchair always along the line with the stairway step edge parallel straight-line, the fluctuation of its center of gravity is very little, it is very steady to move.But the existing equipment that appears on the market.Complex structure, the cost cost is high.Ultra far away the ability to accept scope in sale price of market from the customer.

Further, described sole is provided with the mechanism for assembling-disassembling of locking that horizontal direction just can be carried out dismounting, and dismounting speed is fast, and the easy disassembly transportation had both guaranteed structural strength, also makes the equipment carrying easy.
Further, the both sides of two parallel longerons of described sole are provided with the platform steering swivel system, with the control direction of travel.
Further, also be provided with expansion tightening wheel on the described sole, link to each other, with the tightness of control crawler belt with crawler belt.
Further, also being provided with lockable mechanism on the described sole, is quiescence with the control cart for travelling up or down stairs.
Further, described power drive system comprises battery, motor, change speed gear box and the power-transfer clutch that links to each other successively.Motor is a heavy-duty motor, and battery is a high capacity environmental protection lithium cell, has increased the stroke mileage, has increased load capacity.
Described power drive system comprises the environment-friendly battery of 36 volts of continuous successively high capacity, 36 volts heavy-duty motor and full aluminium precision gearbox, and power-transfer clutch.
Further, described master control unit comprises vertical handgrip, and described vertical handgrip is provided with handlebar and control setup, and control setup links to each other with the motor of running gear.
The battery out-put supply reaches change speed gear box to merit to motor, and change speed gear box drives driving wheel, drives caterpillar drive again, and the control setup through master control unit advances, retreats, and climbs the building, actions such as climbing.
In addition, can also be placed on wheelchair on the described cart for travelling up or down stairs of the utility model,, wheelchair is fixed in climb building and walking on the cart for travelling up or down stairs through after leaning on support lockable mechanism, wheelchair behind support, the wheelchair, leaning on the support reciprocating mechanism behind wheelchair strut bar, the wheelchair.
The advantage of the utility model is: simple in structure, compact, camber internal tooth crawler belt design transmitted power is big, and can prevent interference of tooth in the engagement process; Wear resisting property is good, and noise is little during work, has prolonged product service life.Lock mechanism for assembling-disassembling easy disassembly transportation, both guaranteed structural strength, also make the equipment carrying easy.Later-model drive system has increased the stroke mileage, has increased load capacity.
