Pile slipping prevention device of pile driver
The pile slipping prevention device of the pile driver comprises a clamping seat capable of moving towards a clamping position so as to clamp a pipe pile, the clamping seat comprises a first inclined face facing the clamping position, and the first inclined face inclines downwards in the direction facing the clamping position; the movable seat is mounted on the clamping seat in a sliding manner; the movable seat comprises a second inclined surface which is in sliding fit with the first inclined surface; the speed limiting wheel is rotatably arranged on the movable seat, and the periphery of the speed limiting wheel abuts against the pipe pile; a speed limiting structure is arranged on the speed limiting wheel, and when the speed limiting wheel reaches a preset rotating speed, the speed limiting structure limits rotation of the speed limiting wheel; during pile slipping, the pipe pile drives the speed limiting wheel to rotate at a preset rotating speed in an accelerated mode, rolling friction between the pipe pile and the speed limiting wheel is changed into sliding friction, and then the pipe pile drives the clamping base to move in the inclination direction of the first inclined face through the speed limiting wheel so as to clamp the pipe pile. The anti-slip pile device is short in response time, can act at the initial stage of pile slip to clamp the pipe pile, prevents the pile slip distance from being enlarged, and is better in safety.
本发明涉及一种打桩机的防溜桩装置，包括：可朝向夹持位移动以夹持管桩的夹持座，夹持座包括朝向夹持位的第一斜面，第一斜面沿向下且朝向夹持位的方向倾斜；滑动安装在夹持座上的活动座；活动座包括第二斜面，第二斜面与第一斜面滑动配合；以及，可转动地设置在活动座上的限速轮，限速轮的外周抵接管桩；限速轮上设置有限速结构，当限速轮达到预设转速时限速结构限制限速轮转动；溜桩时，管桩带动限速轮加速转动至预设转速，管桩与限速轮之间由滚动摩擦变为滑动摩擦，进而管桩通过限速轮带动夹持座沿第一斜面的倾斜方向移动以夹紧管桩。本发明的防溜桩装置的响应时间短，能够在溜桩初期时动作将管桩夹紧，防止溜桩距离扩大，安全性更好。
