The invention discloses a hoisting machinery safety height limiting device which structurally comprises a lifting rope, a protection device, a limiting switch, a main body, a laser range finder, a mounting frame and a clamping seat. When the hoisting machinery safety height limiting device is used, the lifting rope extends into a protection assembly through a guide-in opening in a movable frame and is conducted to a guide-out opening in a clamping piece through the protection assembly; the lifting rope is guided out through the guide outlet, the lifting rope and the lifting appliance are wound under the action of the winding drum, after the lifting rope is wound to a certain position, the clamping piece moves upwards under the action of the lifting rope to be close to and abut against the limiting switch, and the winding drum stops rotating under the action of the limiting switch, so that the position of the lifting appliance is limited. And the protection assembly assists the movable frame to play a buffering role, so that top rushing caused by lifting of the lifting appliance is avoided.

    本发明公开了一种起重机械安全高度限位装置,其结构包括吊绳、防护装置、限位开关、主体、激光测距仪、安装框、卡接座,本发明进行使用时,吊绳通过活动框上的导入口随之伸入到防护组件内部,在通过防护组件传导到卡固件上的导出口上,吊绳通过导出口随之导出,吊绳在与吊具在卷筒的作用下随之收卷,吊绳在收卷到一定位置后,卡固件在吊绳的作用下会随之上移而靠近抵接在限位开关上,卷筒在限位开关的作用下会随之停止转动,从而对吊具的位置起到限位,再通过防护组件辅助活动框起到缓冲作用,避免吊具提升而造成冲顶。
