Embodiment

The utility model is described below with reference to Figure of description.

As illustrated, a kind of be oriented to crawl device, including supporter 1, and the track 10 in the supporter 1, institute The section for stating supporter 1 is circular or polygon, and some groups of sliding units, the sliding unit are provided with the supporter 1 It is parallel with the section of the supporter 1, therefore multiple sliding units can be set on supporter, in sliding unit described in every group On at least provided with three rollers 3.

When the section of supporter 1 is circular, the supporter 1 is cylindrical drum 11, at same section of the cylindrical drum 11 Three perforation 21 are uniformly provided with face, the roller 3 is in the perforation 21；Or supporter 4 is by three arcuate structures Connector 4 form, roller 3 is between two neighboring connector 4.

When the section of supporter 1 is polygon, the supporter 1 is at least surrounded by three connectors 4, the roller 3 Between two neighboring connector 4；If connector 4 is three, the 4 V-shaped structure of connector, wherein " V " shape The interior angle of structure is 60 °；If the connector 4 is four, the connector 4 is in the form of an " L ", wherein " L " shape structure is interior Angle is 90 °；Now in order to expand application, the use of different-diameter track 10 is adapted to；Therefore in the both sides of the connector 4 Provided with cramping body 2, the cramping body 2 is in the form of an " L ", is equipped with the both sides of the connector 4, and the bottom of cramping body 2 Some bolts hole 5, be bolted between the cramping body 2 and connector 4, the roller 3 positioned at it is described clamping 2 bodies it Between, so when the diameter of track 10 in supporter 1 changes, by adjusting the position between connector 4 and cramping body 2, So as to expand or reduce the size of the inside diameter of supporter 1, and then meet the application demand of different-diameter track 10.

In order to realize the conversion to the movement locus of supporter 1, therefore rotating shaft 6 is provided with the bottom of the track 10, it is described Rotating shaft 6 is vertically arranged with track 10, and the rotating shaft 6 is connected by bindiny mechanism with wall 71 or ground 72；When the rotating shaft 6 is set Put when on wall 71, the bindiny mechanism is bearing 81, and connecting hole 82 is provided with the wall 71, and the bearing 81 is located at In connecting hole 82, one end of the rotating shaft 6 is connected with the bearing 81；When the rotating shaft 6 is arranged on ground 72, the company Connection mechanism is supporting plate 83, and the both ends of the rotating shaft 6 are located at the outside of supporting plate 83, and spacer pin is provided with the both ends of rotating shaft 6 84, the spacer pin 84 of setting is to prevent the double swerve on supporting plate 83 of rotating shaft 6.
