Abstract

This disclosure relates to a walking mechanism comprising a walking unit and a control unit, wherein the walking unit comprises a load frame, a mandrel is fixedly arranged on the load frame in a penetrating manner, an inner shaft sleeve sleeves the mandrel, and the inner shaft sleeve can rotate around the mandrel; at least two walking and supporting components are arranged on two sides of the load frame respectively; each walking and supporting component comprises a big gear wheel, an outer shaft sleeve and a supporting seat shaft sleeve; each big gear wheel fixedly sleeves the inner shaft sleeve, and a plurality of lock pin holes are formed in each big gear wheel; each outer shaft sleeve and the corresponding big gear wheel are arranged side by side, and each outer shaft sleeve movably sleeves the inner shaft sleeve.

Claims

1. A walking mechanism comprising:

a walking unit comprising a load frame, a mandrel, an inner shaft sleeve and a plurality of walking supporting components;

wherein the mandrel is either fixedly arranged on the load frame in a penetrating manner or the mandrel comprises two pieces, each piece of the mandrel fixedly arranged on two sides of the load frame respectively;

the inner shaft sleeve sleeving the mandrel on two sides of the load frame, and the inner shaft sleeve being capable of rotating around the mandrel; and

at least two of the walking supporting components being arranged on two sides of the load frame respectively;

each of the walking supporting components comprising a big gear wheel, an outer shaft sleeve and a supporting seat shaft sleeve;

each big gear wheel fixedly sleeving the inner shaft sleeve, and a plurality of lock pin holes being formed in each big gear wheel;

each outer shaft sleeve and the corresponding big gear wheel being arranged side by side, and each outer shaft sleeve movably sleeving the inner shaft sleeve;

each supporting seat shaft sleeve fixedly sleeving the corresponding outer shaft sleeve;

a telescopic cylinder being arranged on each supporting seat shaft sleeve and being connected with a landing leg;

a control unit comprising a main controller and a plurality of auxiliary control units, the auxiliary control units being arranged on the supporting seat shaft sleeves;

each of the auxiliary control units comprising an auxiliary controller, a gravity sensor, a gyroscope, an electromagnetic pin and a motor;

each auxiliary controller being connected with the corresponding gravity sensor, the corresponding gyroscope and the corresponding electromagnetic pin respectively;

each auxiliary controller being connected with the corresponding motor through a motor drive circuit;

each auxiliary controller being connected with the corresponding telescopic cylinder through a telescopic cylinder drive circuit;

each motor being connected with a small gear wheel, and each small gear wheel being engaged with the corresponding big gear wheel;

the electromagnetic pins being matched with the lock pin holes to realize fixed connection status or relative rotation status of the inner shaft sleeve and the outer shaft sleeves; and

the auxiliary controllers communicating with the main controller.

2. The walking mechanism according to claim 1, wherein when the mandrel is fixedly arranged on the load frame in a penetrating manner, the distances between two ends of the mandrel and the center of the load frame are equal.

3. The walking mechanism according to claim 1, further comprising a damper arranged at two ends of the mandrel respectively, and the dampers are connected with the main controller.

4. The walking mechanism according to claim 1, further comprising a wireless communication module internally, and the main controller communicates with an external upper computer through the wireless communication module;

the upper computer is used for remotely controlling the main controller through the wireless communication module, and the main controller is used for sending working condition signals of the walking supporting components to the upper computer through the wireless communication module.

5. The walking mechanism according to claim 1, wherein that keys are arranged on the inner shaft sleeve, key holes or key grooves are formed in the centers of the big gear wheels, and the keys are matched with the key holes or key grooves.

6. The walking mechanism according to claim 1, wherein each of the walking supporting components is internally provided with an electromagnetic pin, and at least one lock pin hole is formed in each big gear wheel.

7. The walking mechanism according to claim 6, wherein at least three lock pin holes are uniformly formed in the disc surface of each big gear wheel around the circle of each big gear wheel.

8. The walking mechanism according to claim 6, wherein three or four of the walking supporting components are arranged on one side of the load frame;

and the lock pin holes in each of the walking supporting components are arranged in a staggered manner.

9. The walking mechanism according to claim 1, wherein a fixed wheel is arranged at the bottom of each landing leg.

10. The walking mechanism according to claim 1, wherein a sliding spacer bush is further arranged between each big gear wheel and the mandrel.
