Deformation device of crawler belt running system

Abstract

A deformation device of a crawler belt running system comprises a crawler belt, a driving wheel, a frame, a hydraulic cylinder, a front support wheel, inner guide plates, bearing wheels and a rear support wheel. The driving wheel is mounted above one end of an upper frame, the front support wheel is mounted below the other end of the upper frame, the front support wheel is connected with the hydraulic cylinder mounted on the frame, and the rear support wheel and the bearing wheels are mounted on an underframe. In addition, the driving wheel, the front support wheel and the rear support wheel are wrapped in the crawler belt, the inner guide plates are welded on the underframe and contact with the inner surface layer of the crawler belt. By extending and retracting the hydraulic cylinder to change the up and down positions of the front support wheel and the rear support wheel, shape of the deformation device is changed, so that the grounding area of the crawler belt is enlarged when a crawler belt vehicle is driven to run, and driving ability and trapping prevention ability are improved; when the crawler belt vehicle overpasses ridges, the approach angle of the crawler belt is increased, passability of the crawler belt vehicle is effectively improved and application range of the crawler belt vehicle is broadened.

Description

technical field [0001] The invention relates to the technical field of crawler belt travel, in particular to a deformation device for a crawler belt travel system. Background technique [0002] Paddy fields in the south are often planted with rice, and the paddy fields are kept in a humid state for a long time, so the soil is soft and the mud feet are deep, and the operating machinery is easy to slip and sink when working in the field; currently, the tracked vehicles are driven by crawlers, and the grounding area is large, and the grounding specific pressure is small. It has good ditch-crossing performance and is less destructive to farmland and roads, so it is widely used in the driving system of rice field operations in the south. However, the track-type driving mechanism has poor passability and ridge-crossing ability due to the small diameter of the driving wheel and support wheel. If the passability or ridge-crossing ability of the tracked vehicle is to be improved, the...

[0002] Paddy fields in the south are often planted with rice, and the paddy fields are kept in a humid state for a long time, so the soil is soft and the mud feet are deep, and the operating machinery is easy to slip and sink when working in the field; currently, the tracked vehicles are driven by crawlers, and the grounding area is large, and the grounding specific pressure is small. It has good ditch-crossing performance and is less destructive to farmland and roads, so it is widely used in the driving system of rice field operations in the south. However, the track-type driving mechanism has poor passability and ridge-crossing ability due to the small diameter of the driving wheel and support wheel. If the passability or ridge-crossing ability of the tracked vehicle is to be improved, the diameter of the driving wheel and the supporting wheel needs to be increased, and the increase in the diameter of the driving wheel and the supporting wheel will reduce the ground contact area of ​​the tracked vehicle and reduce the driving capacity of the track.
