Telescopic boom of prying trolley
The invention relates to a telescopic boom of a prying trolley. Comprising a rotary base, a first stand column and a second stand column are hinged to the top of the rotary base, a first supporting column is hinged to the top of the second stand column, and a second supporting column is hinged to the end, away from the second stand column, of the first supporting column. The telescopic large arm is supported through the first stand column, the second stand column and the first supporting column, the telescopic large arm is supported through the stand column oil cylinder, the stability of the whole equipment can be improved when the telescopic large arm tilts and stretches out and draws back, and the sliding gap between the large arm outer barrel and the large arm inner barrel is adjusted through the sliding block assembly; when external force exceeds a set safety value, the overflow valve reduces flow, the hammer pitching oil cylinder stretches out and draws back to keep pressure in an oil cavity of the hammer pitching oil cylinder within a safety range, the overflow valve and the double-hydraulic-control one-way valve are used in cooperation, pressure maintaining can be conducted for a long time, and the safety of the whole equipment is improved. Therefore, the durability is improved.
本发明涉及一种撬毛台车的伸缩臂架。包括回转底座，所述回转底座顶部铰接有第一立柱和第二立柱，所述第二立柱顶部铰接有第一支撑柱，所述第一支撑柱远离第二立柱的一端铰接有第二支撑柱。本发明通过第一立柱、第二立柱以及第一支撑柱支撑伸缩大臂，通过立柱油缸支撑伸缩大臂，可以在伸缩大臂俯仰和伸缩的时候增加整个设备的稳定性，通过滑块组件调节大臂外筒和大臂内筒之间的滑动间隙，确保伸缩大臂能保持平稳的伸缩动作，提高整个设备的稳定性，当外力超过设置的安全值时，溢流阀减小流量，锤俯仰油缸伸缩来保持锤俯仰油缸油腔内压力处于安全范围内，溢流阀和双液控单向阀配合使用，可长时间保压，以此来提升耐久度。
