Self-travelling device of self-travelling geotechnical engineering survey static pressure equipment

Abstract

The invention discloses a self-travelling device of self-travelling geotechnical engineering survey static pressure equipment. The self-travelling device comprises a static pressure pile machine body,and further comprises a self-travelling mechanism, the self-travelling mechanism and the static pressure pile machine body are mounted through a rotating seat, the self-travelling mechanism comprisesa base, the base and the static pressure pile machine body are mounted through the rotating seat, two first rotating shafts are rotationally connected into a cavity of the base, first gears are mounted on the two first rotating shafts correspondingly, the two first gears are connected in a meshing mode, a motor mounting seat is fixedly connected to the outer wall of the base, and a driving motoris mounted at the top of the motor mounting seat. According to the self-travelling device, the central driving motor simultaneously drives four track gears to rotate in the same direction, thus the four-gear driving purpose is achieved, power distribution of the self-travelling mechanism is more uniform, power output is more powerful, and thus the self-travelling device can adapt to more harsh environments.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering investigation, in particular to a self-propelled device of a self-propelled static pressure equipment for geotechnical engineering investigation. Background technique [0002] Static pressure pile: through the pile pressure mechanism of the static pile driver, the self-weight of the pile driver and the counterweight on the frame provide the reaction force to press the prefabricated pile into the soil. In geotechnical engineering investigation, it is to use this pile sinking process to drive the probe rod into the rock to obtain rock samples. In order to facilitate mobile transportation, a mobile mechanism is installed on the static pile machine. There are two types of mobile mechanisms in the prior art, one is a roller mechanism, and the other is a crawler mechanism. The crawler mechanism has the advantage of strong grip and is used Widely used in many large equipment. [0003] ...

Problems solved by technology

[0003] However, the crawler mechanism in the prior art is usually provided with two driving wheels and two driven wheels. By driving the driving wheels to rotate, relying on the meshing force of the track and the driven wheels to drive the driven wheels to rotate. This power output is too dependent on the two driving wheels. Wheels, resulting in uneven power output, making the crawler mechanism not strong enough to operate, especially when encountering terrain conditions such as climbing, the crawler mechanism is very difficult to operate
