The invention discloses an elevator counterweight guardrail device used in the technical field of elevator safety. The main technical scheme is as follows: counterweight guide rails are mounted in a hoistway, a counterweight buffer is mounted in a hoistway bottom pit, two sides of a counterweight frame are in sliding connection with the guide rails, left upper brackets and left lower brackets are sequentially mounted on the counterweight guide rail on the left side from top to bottom, and right upper brackets and right lower brackets are sequentially mounted on the counterweight guide rail on the right side from top to bottom; a bottom end bracket is installed at the bottom end of the counterweight guide rail on the left side, and a travel switch is installed on the bottom end bracket; and an upper guardrail is installed on hooks formed by the left upper brackets and the right upper brackets through guide sleeves, a lower guardrail is installed on hooks formed by the left lower brackets and the right lower brackets through guide sleeves, and a pressing plate is installed at the bottom end of the left side of the lower guardrail and acts on the travel switch. In the maintenance process of the counterweight buffer and the counterweight frame, the counterweight guardrails can be safely and rapidly disassembled and assembled, neglected assembly of the counterweight guardrails is prevented, meanwhile, the personal safety of operators is guaranteed, and the operation intensity is reduced.

    本发明公开了用于电梯安全技术领域中的一种电梯对重护栏装置,其主要技术方案是:对重导轨安装于井道中,对重缓冲器安装于井道底坑,对重架两侧与导轨滑动连接,左上支架和左下支架从上至下依次安装于左侧的对重导轨,右上支架和右下支架从上至下依次安装于右侧的对重导轨;底端支架安装在左侧的对重导轨底端,行程开关安装在底端支架上;上护栏通过导向套安装在左上支架和右上支架形成的挂钩上,下护栏通过导向套安装在左下支架和右下支架形成的挂钩上,压板安装在下护栏左侧底端,并作用于行程开关。本发明在进行对重缓冲器和对重架维护保养过程中,能够安全快速地拆装对重护栏,防止对重护栏的漏装,保障作业人员的人身安全、降低作业强度。
