Embodiment Construction

[0020] Attached below figure 1 - attached Figure 4 , to illustrate the two-dimensionally movable runner with a fixed rotating shaft.

[0021] In the runner of this embodiment, the side profile of the sub-wheel is drum-shaped, that is, its working profile is composed of two arcs. The single-row sub-wheel 6 is made up of four sub-wheels 1, and each sub-wheel 1 is installed and connected to the sub-wheel shaft 3 through the sub-wheel frame 2 fixed on the wheel hub 5. For the convenience of installation and maintenance, the sub-wheel shaft 3 is also provided with sub-wheels. Axle limit card 4. The wheel axle of this runner is fixed form, so can not swing phenomenon. The single row of sub-wheel frames is distributed with four sub-wheel frames whose rotating shafts are perpendicular to each other, and the sub-wheels can only rotate along the direction of the wheel axis, thus constituting the degree of freedom of lateral movement. In order to ensure the stability of the movement...

Abstract

The invention relates to a method for arranging a shifting carrying platform of wheels based on rotating shaft fixed type two-dimensional motion, which belongs to the technical field of shifting carrying platforms. The method comprises the following steps: achieving certain basic single straight line motion according to the following arrangement mode: arranging a first driving wheel and a second driving wheel, wherein the included angle between the direction of the basic single straight line motion and the axial line of the first driving wheel is phi, the included angle between the direction of the basic single straight line motion and the axial line of the second driving wheel is -phi, and phi is more than 0 degree and less than 180 degrees; achieving pure rotation motion of the platform according to the following arrangement mode: arranging the included angle between the axial lines of the two driving wheels to be at least 0 degree; and arranging all driving wheels of the platform according to the two rules, wherein the driving wheels are the wheels based on the rotating shaft fixed type two-dimensional motion. The shifting carrying platform has stable and flexible motion and large bearing capacity, is convenient to mount and maintain, and can satisfy the requirement on performing shifting carry in a small space.

Description

technical field [0001] The invention relates to a transfer platform, in particular to a free transfer platform using two-dimensionally movable runners with fixed rotating shafts. Background technique [0002] The transfer platform widely used at present all adopts the traditional integral runner (the hub, the spoke and the tire are integrated). This runner has a simple structure and is easy to manufacture and replace. However, since this type of runner can only roll along the direction perpendicular to the wheel shaft, the steering of the transfer platform needs to be realized by a steering mechanism, which also requires a large space for movement. The freedom of movement of such transfer platforms is greatly restricted. Therefore, there is a lack of sufficient mobility in places where the operating space is limited. [0003] At present, there are also a small number of transfer platforms that use the mobile technology based on the Macram wheel (also known as the Swedish w...
