Cement rotary spraying device for foundation construction
The invention relates to the field of foundation engineering, in particular to a rotary cement spraying device for foundation construction, which comprises a chassis and a plurality of knife rest assemblies, a central cylinder is arranged in the center of the upper side of the chassis, and each knife rest assembly comprises a first support rod, a second support rod, a knife rod, a first sliding sleeve and a second sliding sleeve; the inner ends of the first support rod and the second support rod are fixed in the central cylinder; the lower end of each cutter bar penetrates through the base plate, upwards penetrates through a second sliding sleeve arranged on the second supporting rod in a sleeving mode from the lower end of the cutter bar and is connected with a first sliding sleeve arranged on the first supporting rod in a sleeving mode through a telescopic sleeve rod, and a second compression spring is arranged in the telescopic sleeve rod. Each cutter bar and the corresponding second sliding sleeve penetrating through the cutter bar are connected with the adjacent cutter bar and the corresponding second sliding sleeve penetrating through the cutter bar through a cross bar set, so that when the lower end of one cutter bar is blocked by downward drilling of a hard block and moves upwards relative to the cutter bars on the two adjacent sides, the second sliding sleeves penetrating through the cutter bars on the two adjacent sides are driven by the cross bar set to get close to the cutter bars on the two adjacent sides. And removal of hard blocks below the blocked cutter bar is accelerated.
本发明涉及基础工程领域，具体涉及一种用于基础施工的水泥旋喷装置，包括底盘和多个刀架组件，底盘上侧中心设置有中心筒，每个刀架组件均包括第一支撑杆、第二支撑杆、刀杆、第一滑套和第二滑套，第一支撑杆与第二支撑杆平行且内端均固定于中心筒；每个刀杆下端穿过底盘，且从其下端向上穿过一个套于第二支撑杆的第二滑套并与一个套于第一支撑杆的第一滑套通过伸缩套杆连接，伸缩套杆内设置有第二压簧；每个刀杆及其穿过的第二滑套与其相邻的刀杆及其穿过的第二滑套通过交叉杆组连接，以在其中一个刀杆下端遇到硬块向下钻进受阻而相对于相邻两侧刀杆向上移动时通过交叉杆组带动相邻两侧刀杆穿过的第二滑套向其靠拢，加快受阻刀杆下方硬块的去除。
