The invention discloses a steel wire rope anti-separation alarm device and a crane trolley comprising the alarm device, and belongs to the technical field of cranes. The invention aims to provide thetechnical scheme for solving the problem of how to realize alarming when a separation phenomenon occurs, and the technical scheme is applied to the crane trolley, so that the occurrence of such safetyaccidents is reduced. The steel wire rope anti-separation alarm device comprises a horizontal rod and a microswitch, wherein the horizontal rod is used for being arranged on the upper side of a fixedpulley to prevent a steel wire rope from separation; and the microswitch and the horizontal rod can move relatively, the microswitch is used for being connected into a safety loop of a crane, and themicroswitch is triggered after the horizontal rod moves to give an alarm for the separation phenomenon. According to the steel wire rope anti-separation alarm device and the crane trolley comprisingthe alarm device, the horizontal rod is arranged at the upper end of the fixed pulley, and the anti-separation purpose is achieved through the horizontal rod; and the right end of the horizontal rod is provided with the microswitch capable of sensing the up-down fluctuation of the horizontal rod so that timely alarming can be realized.

    本发明公开了一种钢丝绳防跳槽报警装置及含有该种报警装置的起重机小车,属于起重机技术领域。本发明的目的是提供一种解决发生跳槽现象时如何实现报警的技术方案并将这种技术方案应用在起重机小车上,进而减少此类安全事故的发生。本发明的目的是这样实现的:一种钢丝绳防跳槽报警装置,包括水平杆,水平杆用于设置在定滑轮上侧防止钢丝绳跳槽;微动开关,微动开关与水平杆之间可相对移动;微动开关用于接入起重机安全回路,通过水平杆在移动后触发微动开关实现针对跳槽现象的报警。本发明通过在动滑轮的上端设置水平杆,利用水平杆来实现防跳槽的目的。水平杆的右端设置一个能感应水平杆上下波动的微动开关,能做到及时报警。
