Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0032] Such as Figure 1 to Figure 3 As shown, the present invention provides a pillar-holding step-up robot, comprising a chassis frame 1, the upper end of the chassis frame 1 is connected with a lifting frame 2 which can move up and down; the lifting frame 2 is connected with a pillar-holding rotating mechanism 3. The column-holding rotation mechanism 3 can hold the column 4 on one side of the step 10 tightly and drive the chassis frame 1 to rotate around th...

Abstract

The invention provides a column holding type step-up robot. The robot comprises a chassis frame. The upper end of the chassis frame is connected with a lifting frame in an up-down moving mode. The lifting frame is connected with a column holding and rotating mechanism. The column holding and rotating mechanism can hold a stand column located on one side of a step and can drive the chassis frame torotate around the stand column. The lower end of the chassis frame is provided with at least one positioning universal ball. The at least one positioning universal ball is located below the column holding and rotating mechanism. When the at least one positioning universal ball abut against the outer surface of the lower end of the stand column, the column holding and rotating mechanism can hold the outer surface of the upper end of the stand column. The column holding and rotating mechanism at the upper end of the chassis frame is matched with the positioning universal ball at the lower end of the chassis frame to improve the fit precision of the column holding type step-up robot and the stand column. Side tipping of the column holding type step-up robot in the lifting process is effectively prevented so that the column holding type step-up robot can achieve the more stable effect when stepping up.

Description

technical field [0001] The invention relates to the field of robots, in particular to a pillar-holding type step-climbing robot. Background technique [0002] Most of the robots that can go up the steps on the market now use a crawler structure. This kind of chassis has a large mass, slow moving speed, and inflexible movement. When climbing the steps, it will cause huge pressure on the edge of the stairs, which is easy to cause damage to the steps. The vertical height span cannot be too large, so that the step-up robot of this crawler structure is not very adaptable to the external environment, and has great limitations when going up and down steps. [0003] At present, there is a step-up robot that uses external columns. The specific mechanical structure is that the entire chassis is divided into two layers. The cylinder body and internal piston of the cylinder are respectively fixed on the upper and lower layers of the chassis, so that the chassis can be realized through t...
