Abstract
The invention relates to a loading vehicle for conveniently climbing stairs. The loading vehicle comprises a loading box, tracks respectively fixed at the left and right edges of the loading box and capable of rotating, and a pull rod connected with the loading box, wherein the tracks are engaged to more than four wheels evenly distributed in the tracks and rotated through the driving of the tracks; the radiuses of the two wheels at the front and back ends of the tracks are one half of the radiuses of the rest wheels to take the shape of an inverted trapezoid; two bearing rods are fixedly connected below the loading box; and the two ends of the bearing rods are respectively in rolling shaft connection with the centers of two wheels in the middle of the tracks at the two edges. In the stairs climbing process, heavy objects are put in the loading box, and then the pull rod is pulled to easily pull the heavy objects upstairs according to the inclined surface power saving principle.
Description
Technical field
The present invention relates to a kind of load-carrying vehicle, specifically a kind of load-carrying vehicle facilitating stair climbing.
Background technology
Now no matter the more and more of building are lived in city or rural area, all can have elevator for skyscraper (mainly refer to more than 8 layers), and the building of less than 8 layers does not just have elevator, people buy article at ordinary times and carry or shoulder Weight upstairs climbing and go home gruelling, especially old man, shoulders motionless at all.
Summary of the invention
The present invention conveniently with Weight upstairs climbing ladder, provides a kind of load-carrying vehicle facilitating stair climbing.
The present invention is realized by following measures: a kind of load-carrying vehicle facilitating stair climbing, comprises basket, the right and left of basket is fixed with the crawler belt that can rotate respectively, the pull bar be connected with basket; Described crawler belt be no less than four be evenly distributed on and the wheel rotated can be driven to be engaged mutually, in inverted trapezoidal by crawler belt in crawler belt; Be fixedly connected with two bearing bars below described basket, the two ends of bearing bar are that roller bearing is connected with the center of two wheels in the middle of the crawler belt of both sides respectively.
The load-carrying vehicle facilitating stair climbing of the present invention, the radius of two wheels of described crawler belt rear and front end is the half of the radius of all the other wheels.
The of the present invention load-carrying vehicle facilitating stair climbing, described inverted trapezoidal crawler belt, the acute angle of the angle of its inside is between 45 degree to 60 degree.
The load-carrying vehicle facilitating stair climbing of the present invention, described wheel is preferably 6.
The load-carrying vehicle facilitating stair climbing of the present invention, described basket is square casing.
The load-carrying vehicle facilitating stair climbing of the present invention, described basket and pull bar are that axle is connected.
The invention has the beneficial effects as follows: in stair climbing process, weight is put into basket, then pull pull bar, just according to the laborsaving principle in inclined-plane, can will pull on stair noon easily.
Accompanying drawing explanation
Fig. 1 represents the structural representation of the load-carrying vehicle facilitating stair climbing.
In figure: 1, basket 2, pull bar 3, crawler belt 4, bearing bar.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is explained.
As shown in Figure 1, the present invention is a kind of load-carrying vehicle facilitating stair climbing, comprises basket 1, the right and left of basket 1 is fixed with the crawler belt 3 that can rotate respectively, the pull bar 2 be connected with basket 1 front; Basket 1 is square casing, with pull bar 2 for axle is connected, can adjust the direction of pull bar 2 at any time; Crawler belt 3 is engaged mutually with 6 rotary wheels be evenly distributed in crawler belt 3, and wherein the radius of two wheels on both sides is the half of middle four wheels radius, makes crawler belt 3 in inverted trapezoidal; With two bearing bars 4 below basket 1, the two ends of bearing bar 4 are connected to the center of two wheels in the middle of both sides crawler belt 3 respectively in roller bearing.
In the process of going upstairs, according to the laborsaving principle in inclined-plane physically, we only need to pull pull bar 2 just labour-saving weight can be brought up to stair.
