Rock foundation excavation equipment for municipal pipeline installation

The invention discloses a rock foundation excavation equipment for municipal pipeline installation. The equipment comprises a supporting frame. Wheels are installed at the bottom of the supporting frame, and a driving mechanism and a cutting mechanism are arranged on the supporting frame. The cutting mechanism comprises a plurality of cutting blade sets which are sequentially arranged from front to back, and each cutting blade set is installed below a horizontal beam of the supporting frame through a variable suspension with the adjustable length. Each cutting blade set comprises a plurality of circular saw blades which are coaxially fixed, and the circular saw blades included in all the cutting blade sets gradually lessen from front to back. All the cutting blade sets are connected with the driving mechanism through chains, and the driving mechanism drives the cutting blade sets to rotate so as to complete rock cutting. According to the excavation equipment, grooves are cut in rock, and the excavation equipment has the advantages of being small in construction occupied area, lower in noise and vibration compared with rock crushing and easy to operate for workers.

本发明公开了一种市政管道安装用岩石基础开挖设备，包括支撑架，支撑架的底部安装有车轮，所述支撑架上设有驱动机构和切割机构；所述切割机构包括若干个前后依次排列的切割片组，每一个切割片组通过一个长度可调的可变悬架安装于支撑架水平梁的下方；每一个所述切割片组均包括若干片同轴固定的圆锯片，所有的切割片组包括的圆锯片数量从前至后逐渐减少；所有的切割片组均通过链条与所述驱动机构连接，由所述驱动机构驱动切割片组旋转进而完成岩石的切割。该开挖设备采用切割的方式在岩石上切出沟槽，具有施工占地面积少、与破碎岩石相比噪音小、振动小以及易于工人操作的优势。
