Embodiment Construction

[0070] The present invention will be further described below in conjunction with accompanying drawing:

[0071] Referring to Fig. 1, 2, 3, 6, the crawler-type traveling device of the present invention, a kind of crawler-type traveling device, comprises two identical traveling units connected by an integrated frame, each traveling unit comprises a crawler belt, a front machine frame and the rear frame, and the track is supported by the roller group set on the front frame and the rear frame, including the driving roller, which is connected with the track drive mechanism; the front frame and the rear The lower frame is hinged, and the lower redirecting roller is arranged at the hinge point, and a gap is formed between the front frame and the rear frame under the lower redirecting roller. The roller group comprises the driving roller 207 positioned on the front frame 220, the tension roller 215, the first reversing roller 212 of the top, the lower small pressure roller 217 positio...

Abstract

The invention involves a crawler walking device and the climb-stair chairs using the device. The crawler walking device includes two same walking units, each walking unit includes crawler, fore frame and rear frame, the crawler is supported by the roller group installed on fore frame and rear frame, the roller group includes active roller, the active roller is connected with crawler drive device; the fore frame and rear frame are pivoted, lower diverted roller is installed below the pivoting point, and the lower part of the lower diverted roller forms notch between the fore frame and the rear frame. The advantages of the invention: rational structure, low cost and good use effect, it can climb the ramps which slope is less than or equal with 45 degrees and the stairs in the same degrees by itself. The armchair can run in staircases of ordinary resident domestic buildings completely. When the armchair runs on flat ground, it has climbing-slope function of 45 degrees, it has broad application scope and can more fully meet the activities requirements of the mass who walk inconveniently.

Description

technical field [0001] The invention relates to a walking device, in particular to a crawler type walking device and a stair climbing chair using the device. Background technique [0002] Most of the existing walking devices use a group of driving wheels and driven wheels to cooperate to complete the walking function. However, the walking devices of this type of structure can only walk on flat ground and cannot climb stairs. Conventional tracked running gear is capable of climbing stairs with moderate slopes and small steps. In order to meet the needs of climbing stairs, the latest remote control robot PackBot developed by Intelligent Robot Company and the urban combat robot developed by iRobot Company of the United States add an auxiliary crawler device for guidance on the basis of each main crawler walking device. The device is used in conjunction with the main crawler-type traveling device, and assists the main crawler-type traveling device to complete the function of cl...
