Abstract
The utility model relates to a carrying cart capable of easily climbing stairs. The carrying cart comprises an object box, rotary crawler belts respectively fastened on the left side and the right side of the object box and a pull rod connected with the object box, wherein the crawler belts are engaged with at least four wheels evenly distributed in the crawler belts and rotating driven by the crawler belts; radius of two wheels on the front end and the back end of each crawler belt are the half of the radius of the rest wheels; the four wheels and the crawler belt are in a shape of an inverted trapezoid; two bearing rods are fixedly connected under the object box; and two ends of each bearing rod are respectively in a roller connection with a center of the two wheels on the middle of the crawler belts on two sides. During stair climbing, a heavy object is placed in the object box and then the pull rod is pulled, so the heave object can be easily pulled up the stairs based on a slope-effort saving principle.
Description
Technical field
The utility model relates to a kind of load-carrying vehicle, specifically a kind of load-carrying vehicle that facilitates stair climbing.
Background technology
Now no matter the more and more of building are lived in city or rural area, for skyscraper (mainly referring to more than 8 layers), all can have elevator, and 8 layers of following building just do not have elevator, people buy at ordinary times article and are carrying or shouldering Weight upstairs climbing and go home gruelling, especially old man shoulders motionless at all.
Summary of the invention
The utility model with Weight upstairs climbing ladder, provides a kind of load-carrying vehicle that facilitates stair climbing for convenient.
The utility model is realized by following measures: a kind of load-carrying vehicle that facilitates stair climbing, comprises that the right and left of basket, basket is fixed with respectively the crawler belt that can rotate, the pull bar being connected with basket; Described crawler belt and the wheel phase interlock that can drive to rotate by crawler belt in crawler belt that is evenly distributed on that is no less than four, be inverted trapezoidal; Described basket below is fixedly connected with two bearing bars, and the two ends of bearing bar are roller bearing with the center of two wheels in the middle of the crawler belt of both sides respectively and are connected.
The load-carrying vehicle that facilitates stair climbing of the present utility model, half of the radius that the radius of two wheels of described crawler belt rear and front end is all the other wheels.
The load-carrying vehicle that facilitates stair climbing of the present utility model, described inverted trapezoidal crawler belt, the acute angle of the angle that it is inner is that 45 degree are between 60 degree.
The load-carrying vehicle that facilitates stair climbing of the present utility model, described wheel is preferably 6.
The load-carrying vehicle that facilitates stair climbing of the present utility model, described basket is square casing.
The load-carrying vehicle that facilitates stair climbing of the present utility model, described basket is that axle is connected with pull bar.
The beneficial effects of the utility model are: in stair climbing process, weight is put into basket, then pull pull bar, just can, according to the laborsaving principle in inclined-plane, will pull on stair noon easily.
Accompanying drawing explanation
Fig. 1 represents to facilitate the structural representation of the load-carrying vehicle of stair climbing.
In figure: 1, basket 2, pull bar 3, crawler belt 4, bearing bar.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is made to specific description.
As shown in Figure 1, the utility model is a kind of load-carrying vehicle that facilitates stair climbing, comprises that the right and left of basket 1, basket 1 is fixed with respectively the crawler belt 3 that can rotate, the pull bar 2 being connected with basket 1 the place ahead; Basket 1 adopts square casing, is convenient to place weight; Basket 1 for axle is connected, can be adjusted the direction of pull bar 2 with pull bar 2 at any time; Crawler belt 3 be no less than 4 rotary wheel phase interlocks that are evenly distributed in crawler belt 3, in order to make crawler belt 3 operational effects better, adopted 6 rotary wheels that are evenly distributed in crawler belt 3; Wherein the radius of two of both sides wheels is half of middle four wheels radius, makes crawler belt 3 be inverted trapezoidal, and for the ease of load-carrying vehicle stair climbing, the acute angle of inverted trapezoidal crawler belt 3 its inner angles is that 45 degree are between 60 degree; Basket 1 below is with two bearing bars 4, and the two ends of bearing bar 4 are respectively the center that roller bearing is connected to two middle wheels of both sides crawler belt 3, make basket 1 more durable.
In the process of going upstairs, according to the laborsaving principle in the inclined-plane in physics, we only need to pull pull bar 2 just can labour-saving weight be brought up to stair.
