Description

Bottle gas is climbed building and loading and unloading Labour-saving car

The present invention relates to the laborsaving transportation means of a kind of mechanical type.Be specially adapted to Labour-saving car for Weight upstairs climbings such as single realization carrying bottle gass.

Along with enlarging day by day of bottle gas user and increasing day by day of skyscraper resident family, the carrying bottle gas upstairs especially for power weak person, an independent people to finish carrying work and is just seemed very difficult.So the building Labour-saving car of climbing of present all formula formulas arises at the historic moment.The various satellite wheel of appreciiable cart for travelling up or down stairs on the market, the people will exert oneself up to draw getting on the bus down, and the satellite wheel alternately contacts step and realizes action upstairs.Its greatest drawback is laborsaving inadequately, because the one-level of whenever advancing all must directly make the satellite wheel overcome gravity by last towing tension and the step resistance is up carried; In addition, the fixedly aplysia punctata radius limit of satellite wheel the applicability of, height wide to the different size step.Except climbing the building link, also to be that general force weak person is difficult to single finishing with portable the mode that moves up for entrucking and when unloading whole bottle coal gas.

The present invention is based on laborsaving, safety, multipotency and be purpose and design a kind of bottle gas and climb the building Labour-saving car, entrucking, overall process such as go upstairs, unload are by being alone to finish leggiero.

In order to realize laborsaving this basic goal, the present invention has used the mechanism of lever to be designed to as shown in Figure 1 structure.The vehicle frame that main car bar, handgrip bar and cross bar are formed loads gas-jar on it, and by lower supporting rod, last railing and firm adhesive tape gas-jar is positioned, and its center of gravity G is dropped in the safety and steady scope.The end of vehicle frame is provided with the activity that can bend Zhe downwards and takes turns mechanisms such as arm and front-wheel, and is provided with work at main car bar stage casing center of gravity correct position.But brace and alive down than forming the triangular shape support that suitable included angle A is arranged behind brace and the Zhe connects with vehicle frame mutually by main shaft before the belt wheel.The level of living down among the figure is stretched out and is partly defined main car bar with the suitable included angle B between the brace before the belt wheel, and this car its front-wheel trailing wheel and pin glue when step is shelved are all supportted within the horizontal direction size safe range that drops on all size step.

When climbing the building, car forefathers after.But brace is locked into state straight by semi-girder with knot that can be undone by a pull behind the Zhe, and the deadlocked ground of the trailing wheel of triangular shape support and pin is firmly supporting whole vehicle frame.Both hands at first with the handgrip bar toward pressing down, vehicle frame then is balance pivot with the main shaft, front end upwards rises, movable wheel arm is just around the curved downwards Zhe of spring shaft when front-wheel is subjected to stopping of step vertical dimension H, front-wheel plays the effect of the main car pole length of automatic shortening, so can be crossed height H and be raised to a step.Thereafter, movable wheel arm recovers state straight again under the spring force effect.Then, the handgrip bar is up pushed away, front-wheel just is moved to the place, right angle of place step, at this moment, front-wheel becomes the fulcrum of vehicle frame lever, and the triangular shape support is unsettled because of carrying on the main shaft, but but owing to brace behind the Zhe is longer, the effect of himself center of gravity is drawn close whole triangular shape support automatically toward frame sides, thus make trailing wheel cross height H be raised in front of the identical last step of wheel.Like this pushing away once pressure one carries out can realizing climbing the building process repeatedly.Downforce that each circulation is required and last thrust are all shifted to each other balance pivot along with center of gravity G and are reduced gradually.Main in theory car bar is long more laborsaving more, considers corner flat-bed tolerable width between the stair but in fact must cooperate; The length of movable wheel arm must consider to adapt to various rise H; Vehicle frame must consider to adapt to all kinds of operators' the height and the laborsaving position at center of gravity G place with the degree of dip of horizontal surface during stable state.The consideration of comprehensive various design factors can make energy laborsaving 2/3rds when climbing the building.In addition, every when reaching last step and entering corner platform place, with alive passing through latch closure is passed through in the work on the vehicle frame by the horizontal sliding that is arranged on the triangular shape support, can realize that then pin glue is liftoff, the laborsaving mode that pushes that front-wheel and trailing wheel land simultaneously.

When carrying out entrucking, but at first the Zhe that makes progress of brace behind the Zhe is risen, and lock it on the vehicle frame with knot that can be undone by a pull by receiving arm, then the movable action of living up and down disappears, and forms the laborsaving horizontal drawing state angle C of vehicle frame and support, as shown in Figure 2.The loading and unloading pad that the height that sets with the present invention is suitable tilts just can move easily on the loading and unloading pad standing upright on ground gas-jar a little.Then, vehicle frame is moved into erectility, movable wheel arm is inwardly curved automatically Zhe under the deadweight effect, and the lower supporting rod height is moved down, and just can insert the runners position of gas-jar, firm adhesive tape on the figure.At this moment, with pin step on slightly hind axle with it as the swing fulcrum, with hand the handgrip bar one is drawn toward pin before gently, gas-jar then fills up with the car loading and unloading that raise, movable wheel arm recovers state straight, and the entrucking process is promptly accused and finished.Trailing wheel landed and can do roping this moment, and is the most laborsaving when correct design state angle C makes center of gravity G drop near the trailing wheel then level land roping.

When unloading, aligning loading and unloading pad props up the vehicle frame of naming a person for a particular job by front-wheel as swing and moves into erectility gently, the inwardly curved Zhe of arm is just taken turns activity in gas-jar its deadweight when stand up position automatically, and vehicle frame descends, and gas-jar then is located on the loading and unloading pad.Moving method with identical inclination when the entrucking just can move on to gas-jar on the ground like a cork.

Downstairs process is non-weight mode usually, but the present invention also sets up the mechanism downstairs when being necessary, but is realized by the state transformation mechanism assists of installing between the brace behind the Zhe, as shown in Figure 4.It downstairs is inverse process upstairs, the people is getting off last, by preceding crop rotation balance pivot, the hand grip bar draws vehicle frame towards front direction holder, the triangular shape support is at first unsettled and to next step landing, pin glue is unsettled when contacting to earth by the compression spring uplift force of state transformation wheel, make the conversion wheel slide a bit of distance back up to trailing wheel land motionless till.At this moment, the handgrip bar is pulled down, because of action of gravity is arranged, spring force is cancelled, state transformation wheel is said with respect to pin glue and is moved, and is transformed into the motionless deadlockedly state of pin, and as the swing fulcrum of whole locomotive body, treat drop-downly when swinging to front-wheel and going out high step width W place, self gravitation drops to next identical step of trailing wheel front-wheel.Carry out repeatedly then can going downstairs.

At ordinary times, in order to reduce the occupation of land space of dolly, also can consider, but top rod and main car bar are made the foldable, to reach small and exquisite portable effect the lower supporting rod on the vehicle frame.
