技术领域 technical field
本发明涉及一种液压顶推装置，特别涉及一种蜂窝式液压顶推装置。 The invention relates to a hydraulic pushing device, in particular to a honeycomb hydraulic pushing device.
背景技术 Background technique
在现代的工程施工作业中，广泛地使用液压油缸顶推装置。当顶推的距离很短、精度要求很高时，现有的液压顶推装置往往无法满足要求。这是因为对于单个的液压顶推油缸，如果顶推的行程很短，活塞杆的伸缩缸距离就很短，如果再考虑油漏和密封等因素，精度要求很难保证。 In modern engineering construction operations, hydraulic cylinder jacking devices are widely used. When the pushing distance is very short and the precision requirement is high, the existing hydraulic pushing devices often cannot meet the requirements. This is because for a single hydraulic jacking cylinder, if the jacking stroke is very short, the telescoping cylinder distance of the piston rod is just very short, and if factors such as oil leakage and sealing are considered, the accuracy requirement is difficult to guarantee.
目前尚无相关专利提出有效的解决方案。 At present, there is no relevant patent to propose an effective solution.
