Engineering machinery pile clamping control method and wedge block type tubular pile clamping system
The invention relates to the technical field of engineering machinery control, and discloses an engineering machinery pile clamping control method and a wedge block type tubular pile clamping system.The control method comprises the following steps of mechanical in-place, system power-on, pile clamping work and pile sinking or pile pulling work, digital automatic control is adopted, the maximum pile clamping pressure threshold value of the system is set through a hydraulic control overflow valve, and the pile clamping pressure threshold value of the system is set through the hydraulic control overflow valve; the pipe pile is prevented from being damaged by clamping; the pressure of the system is maintained through the hydraulic control one-way valve and the energy accumulator, so that the requirement that the concrete prefabricated pipe pile is reliably and safely clamped for sinking and pulling operation can be met; according to the pile clamping system, through a software and hardware structure, the pile clamping device applies force to the pile pipe by adding a wedge block type structure, a piston rod of the hydraulic clamping oil cylinder is prevented from directly and vertically acting on the pile pipe, the working reliability and safety of the hydraulic clamping oil cylinder are improved, a horn mouth supporting slope is combined with a wedge block, and a clamping structure with a self-locking function is formed; the state of clamping force loss is avoided, and the requirements of modern building construction can be met.
本发明涉及工程机械控制技术领域，公开了一种工程机械夹桩控制方法及楔块式管桩夹桩系统，其控制方法包括以下步骤：机械就位、系统上电、夹桩工作、沉桩或拔桩作业，采用数字化自动控制，通过液控溢流阀来设定系统最大夹桩压力阀值，确保不把管桩夹坏；通过液控单向阀和蓄能器对系统进行保压，能够满足夹持混凝土预制管桩可靠、且安全地进行沉拔作业的要求；该夹桩系统通过软硬件结构，其夹桩器通过增加楔块式结构将力施加于桩管，避免液压夹紧油缸的活塞杆直接垂直作用于桩管，使液压夹紧油缸的工作可靠性、安全性提高，喇叭口支撑斜面与楔块结合，形成具有自锁功能的夹紧结构，不会出现夹紧力丧失的状态，可满足现代化建筑施工需要。
