Chain crawler vehicle chassis with adjustable height

Abstract

The invention relates to a chain crawler vehicle chassis with the adjustable height. The chain crawler vehicle chassis comprises oppositely arranged chain crawler assemblies, supporting assemblies and a vehicle body fastening assembly, wherein the supporting assemblies are installed on the chain crawler assemblies, and the vehicle body fastening assembly is installed on the supporting assemblies and used for fixing and installing a vehicle body or a crawl device comprising a driving shaft. Rotary knob plunger assemblies used for adjusting the heights of the vehicle body fastening assembly are installed on the chain crawler assemblies in a lateral pulling and positioning mode. Speed reduction box assemblies used for reducing the rotation speed of a drive axle of the vehicle body and increasing the torque are arranged on the vehicle body fastening assembly. Transmission force is driven by a motor of the vehicle body or the crawl device to be transferred to the speed reduction box assemblies. After power is supplied, rolling torque of an axle of the crawl device is transferred to the speed reduction box assemblies through connection flanges, the effects of reducing the rotation speed and increasing the torque are achieved through speed reduction transmission inside the speed reduction box assemblies, the rotation speed of chain wheels is reduced, and the torque is increased, so that chain crawlers are driven to operate, and the crawling function of the vehicle chassis is achieved.

Description

technical field [0001] The invention relates to a height-adjustable chain crawler vehicle chassis. Background technique [0002] Because the pipelines in use will accumulate silt, the thickness of the allowable silt accumulation is also different for pipelines with different diameters, generally less than 1 / 3 of the diameter of the pipeline. [0003] The tire-type vehicle chassis currently on the market often have the following two problems when it is necessary to detect pipelines in operation. Very time-consuming and laborious. The second is that its scope of application is relatively narrow, because the height of the tire-type vehicle chassis is not adjustable, while the diameter of the pipe is changed, and the thickness of the silt accumulated in the pipe is also different, which is not conducive to the operation of the vehicle chassis and is easy to stick If there is mud on it, it is impossible to achieve a good observation effect. [0004] In view of above-mentioned ...
