Abstract
The utility model discloses a load-carrying dual-purpose electricity and hand driven handcart for travelling up stairs. The utility model can transport various objects with convenience and labor saved up stairs through the stair steps, replacing the labor power to bear the load burden. The dual-purpose electricity and hand driven handcart for travelling up stairs is mainly composed of cart wheels, a cart wheel carrier, an axletree, a load bearing rack, a connecting rod, a handle and a ratchet mechanism. By pushing the handle up and down by hand, the cart wheels on the cart wheel carrier rotate sequentially and climb up the steps through the connecting rod and the ratchet mechanism. The utility model has the advantages of labour saving, convenient operation and simple structure, and can use the electricity driven mode at any time while in use.
Description
The utility model relates to the load-carrying cart for travelling up or down stairs that uses on step, be specially adapted to high-rise building delivery than heavy articles.
Along with day being becoming tight of the development in city and building site, the building in city, particularly big, middle city requires to build a building so that skyscraper, in skyscraper, people utilize elevator that article are risen to upstairs, and stay in the people that do not have the lift facility building, then have to than heavy articles some, such as gaholder, grain, coal or the like goes with the manpower carry it upstairs, very painstaking, especially the world today is along with the raising day by day of development of productivity and living standards of the people, and many countries have progressed into aging society, and it heavily upstairs then is impossible or even dangerous thing that the elderly takes.The employed a kind of cart for travelling up or down stairs of current people is by bearing frame, the rotating shaft that links to each other with the bearing frame lower end, respectively there are two wheels that are rotatedly connected with rotating shaft at two ends, the carrying handle that links to each other with the bearing frame upper end, during use weight is placed on the bearing frame, the people upwards draws at car forward position stairway step, when first is taken turns when running into the step facade, another takes turns with previous axle of taking turns is that center of rotation lifts on the step horizontal surface of falling the front higher order, so go round and begin again and upwards promote weight, though this cart for travelling up or down stairs can be carried and heavily climb the building, but still require great effort very much, can not solve the problem of carrying Weight upstairs climbing effortlessly.
The purpose of this utility model is to design a kind of new-type cart for travelling up or down stairs that can promote the Weight upstairs climbing ladder effortlessly.
The said load-carrying cart for travelling up or down stairs of the utility model comprises wheel (1), the axle (3) that vehicle wheel frame of two installation wheels (2) and vehicle wheel frame rotate together, be installed in bearing frame (4) and bont on the axle (3), said bont comprises two ratchets (5,6), two ratchets (7,8), connecting rod (9,10,12), handle (11), anchor shaft (13), bearing seat compositions such as (26).Be installed in two ratchets (5,6) on the axle (3), be meshed with connecting rod (9,10) all-in-one-piece ratchet (7,8) respectively.Ratchet, pawl device can design voluntarily, also can adopt the existing mechanism of bicycle, one of them connecting rod (9) and handle (11) be connected to that point of connection is relatively-movable to be connected, another connecting rod (10) is connected with handle (11) with anchor shaft (13) by connecting rod (12), connecting rod (10) and connecting rod (12) be connected to that point of connection is relatively-movable to be connected, anchor shaft (13) is installed on the bearing frame (4).Bearing frame (4) can be connected by bearing seat between (3) with axle.Bearing seat can directly or indirectly be realized being connected with riveted joint, welding or bolt with bearing frame.During use, before the trammer is pushed into stair with car, upwards lift handle (11), drivening rod (9) rotates counterclockwise around axle (3), stir ratchet (5) with connecting rod (9) for the ratchet of one (7), ratchet (5) drives axle (3) left-hand revolution, vehicle wheel frame drives wheel and climbs up stairway step, meanwhile, handle (11) is by anchor shaft (13) drivening rod (12) left-hand revolution, connecting rod (12) drivening rod (10) clickwise, also do clickwise with connecting rod (10) for one and the ratchet (8) that links to each other with ratchet (6), make between ratchet (6) and the ratchet (8) and be in non-transmission mode of operation this moment, when pressing down handle (11), drivening rod (12) clickwise, connecting rod (12) drivening rod (10) left-hand revolution, ratchet (8) on the connecting rod (10) is stirred ratchet (6) and is driven axle (3) left-hand revolution, vehicle wheel frame drives wheel and climbs the building, simultaneously, connecting rod (9) clickwise, ratchet (5) and ratchet (7) are located and non-transmission mode of operation.Driving handle (11) makes cart for travelling up or down stairs climb the building continuously so up and down, and with due regard to the length of each connecting rod is to alleviate the strength of driving handle.Wheel has 3 wheels at least to the impact of stairway step on each vehicle wheel frame in order to reduce to climb the building.
For car can stably be stood on the ground, on appropriate location, bearing frame (4) below, a supporting leg (17) is set, the structure of supporting leg can adopt the structure of single supporting leg of existing bicycle.
In order to reduce the impact between wheel and the stairway step, and consequent noise, keep scantling of structure reasonable again simultaneously, be preferably in and evenly arrange four wheels on each vehicle wheel frame.
For laborsaving and be convenient to the elderly and use, can storage battery be installed as power supply in the bottom surface of the bearing frame (4) of said cart for travelling up or down stairs, by the motor drives speed reduction gearing, drive axle (3) by the sprocket wheel (16,15) on speed reduction gearing shaft and the axle (3) and rotate, thereby make cart for travelling up or down stairs climb the building with electric power.This moment, handle, the connecting rod of hand hoisting device were inoperative.
Advantage of the present utility model is:
(1) laborsaving, can suitably design length of connecting rod, driving handle just can realize that load-carrying climbs the building gently;
(2) simple in structure, wherein the escapement of more complicated can adopt the escapement that uses on the existing bicycle;
(3) continuous upper and lower driving handle can be realized climbing the building continuously, and easy to operate, impulsive force is little; Also can use electronic mode at any time in the use;
(4) designed cart for travelling up or down stairs not only can be climbed the building, also can loading walking on the level land.
