Abstract
A crawler wheel adopts a mechanical combined device and can successfully solve the problem that a trolley which is loaded is difficult to walk up and down stairs. The crawler wheel consists of a pulley block and a track box. Pulley brackets of the pulley block are connected by using a shaft; two ends of each pulley bracket are respectively provided with a pulley; the brackets are higher than the pulleys; and the pulleys are inwards connected into a ring shape. The track box is in a shape of an opening rectangle; an adjustable long round pulley track is mounted in the middle of the track box; and an upper chamber and a lower chamber in the box can allow the pulley block to run smoothly. Two side wall grooves can prevent the pulley block from sliding and drooping; the lower parts of the two side wall grooves are provided with openings so that the bracket of the pulley block is exposed outside the box to be in contact with edges and corners of stair steps and to stably transit and run. (For a specific structure, please refer to the attached drawing in the abstract.) Crawler wheels are fixed on a trolley body at the inner side of a main wheel of the trolley in a parallel way, and the lower end below the bracket of the pulley block along a linear running orbit is anastomotically connected with the excircle of the main wheel so that the main wheel of the trolley and the crawler wheel stably transit and walk up and down stairs. The crawler wheel can be made into various models as required by using different materials, not only can be used on a household trolley, but also can be used on multiple vehicles and devices, and has quite wide purposes.
Description
Technical field: carrying out car is to be assemblied on the dolly, the mechanical device of stair activity when making things convenient for dolly to bear a heavy burden.The resident of urban and urual areas of whole country is a lot of with the people of dolly, but dolly heavy burden stair activity is very difficult, and the invention of carrying out wheel has solved this problem scientifically and rationally.
Background technology: two wheels about at present in the life there be common dolly, have (about each three take turns into triangular form assemble up and down) of six wheels, about having each one take turns, respectively adorn again on two pull bars 2 or several steamboats or the like.No matter the problem that dolly heavy burden stair activity jolts of all failing to solve of what pattern.
Summary of the invention: the shoe wheel of my invention is made up of assembly pulley and track box, and the pulley bracket of assembly pulley links to each other with axle, and two ends are respectively adorned one and taken turns, and support exceeds pulley, and pulley inwardly is linked to be ring-type.Track box is the opening rectangle, and the oval track of adjustable pulley is equipped with in the centre, and the interior chamber up and down of box can hold the unobstructed operation of assembly pulley.The two side groove can prevent that the assembly pulley landing is sagging, and lower aperture is exposed outside the box assembly pulley support and made it the smooth transition operation with contact stairway step corner angle.
Description of drawings: accompanying drawing 1 is the generalized section of assembly pulley in the track box inboard;
Accompanying drawing 2 is assembly pulley schematic cross-sectional view in track box;
The lower end of accompanying drawing 3 assembly pulley support lower edge linear running tracks and main wheel cylindrical kiss contact scheme drawing.
The specific embodiment: the track box of carrying out wheel is used the parallel connection with car body of bolt for four jiaos, carries out wheel and is installed in dolly main wheel inboard, and the lower end of assembly pulley support lower edge linear running track and main wheel cylindrical kiss connect, so that the dolly smoothly and steadily climbing up and down stairs.
Claims (2)
1. carry out wheel and be made up of assembly pulley and track box, the built-in ring-type assembly pulley of belt supporting frame is around the oval orbital motion of osed top.The transversal surface of track box is the opening rectangle, and the centre is a track, on do not reveal assembly pulley, the assembly pulley support exposes with contact stairway step corner angle in following rectangular aperture place.This installs in use, and assembly pulley can not pass into others' hands, sagging, it is laborsaving to move regular steady and smooth, can make things convenient for pulsation-free to cooperate dolly heavy burden stair activity.
2. the ring-type assembly pulley with the band pulley bracket moves in the oval track cocycle of sealing, cooperates the mode of dolly heavy burden stair activity to design.
