Problems solved by technology

In this way, although it is very convenient to add components in future development, it greatly increases the number of joints, increases the loss along the entire hydraulic system, and also makes the hydraulic system have too many connection points, increasing the hidden danger of oil leakage; The fixing of hydraulic blocks has also become a thorny issue; the distributed arrangement makes it difficult for us to regularly maintain hydraulic components such as accumulators and filters
[0003] This hydraulic system configuration scheme is obviously not enough to support the basic reliability and ease of maintenance of the hydraulic quadruped robot, and the design of a separate hydraulic carrier also increases the repetitive labor of the designer

Abstract

The invention discloses an integrated oil path block for a hydraulic quadruped robot. The integrated oil path block for the hydraulic quadruped robot comprises an overflow valve, a positive pressure piece and an oil path block, and the overflow valve and the positive pressure piece are arranged on the oil path block and are communicated with the interior of the oil path block; the integrated oil path block for the hydraulic quadruped robot further comprises an energy accumulator, a filter and a sensing piece which are all installed on the oil path block, and the energy accumulator and the filter are communicated with the interior of the oil path block; the design difficulty of the hydraulic system of the hydraulic quadruped robot is reduced by establishing the integrated oil path block ofthe aluminum alloy 7075-T6; the integrated oil path block can be integrally disassembled and can be quickly assembled on other foot-type robots, so that the application range of the integrated oil path block is expanded, and the interchangeability is enhanced; and the service life is longer, and the loss is reduced.

Description

Technical field[0001]The present invention relates to the technical field of quadruple robots, particularly an integrated oil block for hydraulic quadruple robots.Background technique[0002]The hydraulic system development of hydraulic quadruple robots is mainly connected to the hose or the hard tube directly, and after considering the needed hydraulic elements (such as accumulators, one-way valves), it is added separately on the line. Most of the time you need to add a separate small hydraulic block to the hydraulic component to be assembled. Thus, although this is convenient in the increase in components in the future, it greatly increases the number of joints, so that the overall loss of the entire hydraulic system increases, which also makes too much connection point of the hydraulic system, increasing the hidden risks of oil. The fixation of the hydraulic block is also a tricky problem; the distributed arrangement makes us difficulty in the regular maintenance of hydraulic compo...
