In practical application, for example when designing upset platform, wherein upset platform is equivalent to a rotator, one end is connected through pivot and fixed hinge support, and support for providing of upset platform one end, and the other end just needs rotatable support to provide the support, if adopt fixing support, in order to realize the support to the upset platform other end, fixing support just must be located the turning radius of upset platform within, at the in-process of upset platform upset, fixing support will take place to interfere with the upset platform, hinder the upset of upset platform, lead to the upset platform can't walk around fixing support and continue the upset. When the overturning support is selected, the overturning support is used for supporting the platform, so that the overturning seat rotates in a single direction, a braking device is needed in the other direction to support the overturning platform, and the overturning seat can only rotate in the single direction opposite to the rotating direction of the overturning platform. When the overturning platform needs to rotate reversely and fall down, the overturning seat rotates reversely and is provided with the braking device, so that the reverse rotation of the overturning platform is hindered, the overturning platform can push the overturning seat open and rotate upwards, and when the overturning platform needs to fall down, the overturning seat cannot rotate and avoid, so that the overturning platform cannot rotate reversely to fall down.

FIG. 2 is a schematic view of the occupying device filling the end of the rotating body B to realize the reverse rotation of the rotating body B;
in the figure: 1. rotator A, 2, rotator B, 3, placeholder device.
The specific implementation mode is as follows:
example 1:
a unidirectional rotation mechanism reverse barrier-free rotation device comprises: rotator A1, rotator B2, rotator A rotator B center all connect through pivot and fixed hinge support, rotator A be unidirectional rotation, the opposite direction rotation is equipped with braking self-lock device, rotator B can realize not being bidirectional rotation when external condition restricts, rotator B be connected with occupy-place device 3.
Example 2:
a method for achieving reverse barrier-free rotation by using the unidirectional rotation mechanism of embodiment 1, the method comprising the steps of:
(1) the rotating body A and the rotating body B rotate in a single direction, wherein the rotating body A rotates in the single direction, a braking device is arranged in the opposite direction, and the rotating body B rotates in the two directions when not limited by external conditions;
(2) the rotating body A can automatically rotate reversely to the previous braking position within a certain angle range through self reverse force, when the rotating body A rotates beyond a set braking angle, reverse braking is triggered, and at the moment, the rotating body A cannot rotate reversely through the self reverse force;
(3) When the rotator B needs to rotate reversely, the occupying device on the rotator B gradually occupies the front end of the rotator B from the outside of the rotating radius of the rotator A and drives the rotator A to rotate, so that the rotator A rotates by a certain angle, the rotating angle is smaller than the braking angle, a rotating space is provided for the reverse rotation of the rotator B, in the process of the reverse rotation of the rotator B, the occupying device always abuts against the rotator A, the rotator A gradually rotates along with the rotation of the rotator B under the action of the self reverse force, and when the rotator B reversely rotates to the braking position of the rotator A, the rotator A stops rotating;
(4) when the rotating body A reaches the braking position, the rotating body A can provide support for the rotating body B.
The rotator A rotates in a unidirectional and continuous way, can rotate in the opposite direction through self reverse force within a certain angle range (when the angle does not exceed a braking angle), namely, the rotator A can automatically rotate in the opposite direction to the previous braking position within the interval of two braking ranges. When the rotating angle of the rotating body A exceeds the set braking angle, the rotating body A enters the next braking interval, and in this case, the rotating body A and the rotating body B can only do rotating motion along a single direction, so that the rotating body B cannot rotate reversely. The method is characterized in that the front end of the rotator B is gradually filled with the front end of the rotator B from the outside of the rotating radius of the rotator A by using an occupying device at the front end of the rotator B to enable the rotator A to rotate for a certain angle from a braking position, so that enough rotating space is provided for the reverse rotation of the rotator B, and the reverse barrier-free rotation of the rotator B is realized.
When rotator B needs the reverse rotation, at first rotate certain angle with rotator B according to former direction of rotation, form certain inclination with rotator A, but not reach the braking position, occupation device draws close to rotator B tip from rotator A's the biggest radius of gyration outward gradually this moment, the in-process occupation device that draws close stirs rotator A anticlockwise, it is rotatory to drive rotator A, for rotator B's reverse rotation provides the space, thereby eliminate rotator A to rotator B reverse rotation's hindrance, realize rotator B's opposite direction barrier-free rotation. In the process of rotating the rotating body B in the reverse direction, the rotating body A rotates along with the rotating body B under the action of the self-reverse force, and the rotating body A does not rotate when rotating to the previous braking position.
Example 3:
the method for realizing the reverse barrier-free rotation of the unidirectional rotating mechanism according to the embodiment 1 or 2 comprises the following specific implementation steps:
when the temporary rotating body B is a power input end, the rotating body a is driven to rotate by the rotation of the rotating body B in combination with the accompanying drawings 1 and 2 of the specification, and because the rotating body a rotates in a single direction and has a braking function during reverse rotation, when the rotating body B rotates in the reverse direction, the rotating body B is obstructed by the rotating body a and cannot rotate continuously, and at the moment, the rotating body a can support the rotating body B. When rotator B need continue the antiport, need earlier rotator B according to the rotatory certain angle of original direction, simultaneously through the occupy-place device, draw close to rotator B's tooth tip gradually outside rotator A's the biggest diameter of gyration, fill up rotator B's tip gradually, the in-process that the occupy-place device was drawn close drives rotator A rotatory, rotator A's rotation angle is less than the braking angle, when the occupy-place device fully occupies rotator B's front end, just rotator A does not have the hindrance to rotator B's antiport. After the occupying device reaches the position, the rotator B can avoid the obstruction of the rotator A and rotate reversely, at the moment, the rotator A automatically follows the rotator B to rotate correspondingly under the action of self reverse rotation force until reaching the braking position, and therefore the reverse rotation of the rotator B is realized.
