Hydraulic control system for ditcher

Abstract

The invention provides a hydraulic control system for a ditcher, and belongs to a mechanical hydraulic engineering device. The system comprises a hydraulic oil tank, a walking unit, a ditching unit, an excavation unit, a ditching adjustment unit and a heat dissipation unit. The system relates to a whole hydraulic control and driving scheme in the ditcher, and under the control of the scheme, the functions of independently controlling caterpillars on two sides of the ditcher, enabling a ditching device and an excavation device to work independently, flexibly adjusting the whole body angle and adjusting the ditching depth can be realized, thereby greatly enhancing the ditcher passing ability on one hand, and greatly enhancing the adaptability of the ditcher to the non-even pavements so as toimprove the ditching efficiency and ensure the ditching quality on the other hand.

Description

technical field [0001] The invention belongs to a mechanical hydraulic engineering device, in particular to a hydraulic control system of a ditching machine. Background technique [0002] With the rapid development of my country's transportation industry, trenchers have been widely used in various engineering construction fields such as high-speed railways, subway expressways, etc., especially in railway pipeline laying projects, and there are more and more demands for similar constructions such as trench excavation. For many years, the mainstream trenching machines in the domestic market have been realized through mechanical transmission, mainly used in the agricultural machinery industry, urban and rural optical cables, etc., with a single working condition and many environmental constraints on the construction site. The current mainstream trenching machines are aimed at different geological conditions. The walking speed of the trenching machine cannot be accelerated or de...

AI Technical Summary

Problems solved by technology

For many years, the mainstream trenching machines in the domestic market have been realized through mechanical transmission, mainly used in the agricultural machinery industry, urban and rural optical cables, etc., with single working conditions and many environmental constraints on the construction site.

The current mainstream trenching machines are aimed at different geological conditions. The walking speed of the trenching machine cannot be accelerated or decelerated according to the construction conditions. The speed of the chainsaw cannot be adjusted. The cutting torque of the chainsaw cannot be adjusted. The groove opened on the slope surface is perpendicular to the horizontal plane, and the construction environment of the trencher cannot be trimmed, resulting in low quality of trench excavation and difficult to improve construction efficiency
