Abstract
A chassis of a trolley capable of pivot steering and universal walking comprises a fixed framework, a universal rotating mechanism and two rolling wheels, wherein the universal rotating mechanism is arranged at one side under the fixed framework and comprises at least one universal wheel, and the rolling wheels are arranged at the other side of the fixed framework and are in triangle arrangement with the universal wheel. By adopting the chassis, the flexibility and the stability can be remarkably improved, and the trolley can safely and stably carry out 360 DEG pivot steering; the walking direction can be changed without changing the direction of a trolley body, so that the trolley has the capability of universal walking; and when the force borne by the trolley is imbalanced, the universal rotating mechanism can automatically adjust so as to avoid the side rollover due to the imbalanced force, so that when the trolley walks, the stability is ensured. The chassis has convenience in operation, little investment, low use cost and simple and light structure.
Description
Technical field
The utility model relates to a kind of walking dolly, especially relates to the chassis of a kind of pivot stud and universal walking dolly.
Background technology
Handbarrow is used very extensively in commercial production, the life at present; The dolly that can carry out pivot stud generally adopts can free-moving cardan wheel; Such as the handbarrow of using in the supermarket, but pivot stud and universal walking, but bearing load is little; When four-wheel receives force unbalance, operate dumb even rollover.In the office can pivot stud and the seat of universal walking, when receiving force unbalance, turn on one's side easily.The dolly that in commercial production, generally adopts is generally supported by two front-wheels and two trailing wheels, and trailing wheel is a cardan wheel, and front-wheel generally is a directional wheel, can not rotate.The operator is go-cart control dolly from behind generally, and the rotation of trailing wheel can make the comparatively convenient control dolly of operator; Four wheels are at the dolly that all is cardan wheel before and after also having.And there is following deficiency in this pattern that turns to: 1, Turning radius is big, is not suitable for using in narrow space; 2, underaction must dolly integral body turns to change direction of travel; 3, when limited location needs J-turn, need adjust the turnover of dolly angle repeatedly, the energy and handling poor of losing time.
Summary of the invention
The purpose of the utility model is to provide the chassis of a kind of pivot stud and universal walking dolly; Can significantly improve dolly alerting ability, stability; And can safety and stability carry out 360 degree pivot studs; Can also when not changing the vehicle body direction, change direction of travel, have the ability of universal walking; When dolly when receiving force unbalance, universal rotating mechanism can be adjusted voluntarily, can avoid because of receive force unbalance cause the rollover, the stability when having guaranteed carriage walking.The utility model is easy to operate, investment is little, use cost is low, structure is simplified light.
For achieving the above object, the technical scheme of the utility model is:
The chassis of a kind of pivot stud and universal walking dolly, it comprises, fixed frame; Universal rotating mechanism is arranged at next side of fixed frame, comprises at least one cardan wheel; Two rollers are divided into the opposite side under the fixed frame, are triangle with the cardan wheel of universal rotating mechanism and arrange.
Further, described fixed frame comprises first fixed mount and middle part and first fixed mount, one end bonded assembly second fixed mount that intersects vertically, and is three-legged structure; Described universal rotating mechanism is installed under first fixed mount, one end, and two rollers are arranged at respectively under the second fixed mount two ends.
Further, the described universal rotating mechanism of the utility model comprises, Connection Block, and its top is connected in fixed frame, and a connection pipe is established in the bottom; Axle sleeve is sheathed on outside the connection pipe under the Connection Block, also establishes bearing between axle sleeve and the connection pipe; The axle sleeve outer rim is established support; Cardan wheel is arranged under the support.
The axle sleeve outer rim of described universal rotating mechanism is symmetrical set establishes three supports and corresponding cardan wheel.
Two adapter plates are set under the described fixed frame, and said Connection Block top is embedded between this two adapter plate, and is connected with connecting panel by bearing pin, axle head cover plate, bolt.
Described connection pipe middle part forms ledge structure, establishes two bearings between axle sleeve and the connection pipe, and the bearing step is provided with tapered roller bearing, deep groove ball bearing up and down respectively.
Described roller is a cardan wheel.
The advantage of the utility model is:
The utility model can significantly improve alerting ability, the stability of walking dolly through universal rotating mechanism, and can safety and stability carry out 360 degree pivot studs, can also when not changing the vehicle body direction, change direction of travel, have the ability of universal walking; When dolly when receiving force unbalance, universal rotating mechanism can be adjusted voluntarily, can avoid because of receive force unbalance cause the rollover, the stability when having guaranteed carriage walking.The utility model is easy to operate, investment is little, use cost is low, structure is simplified light.
