The invention discloses an elevator car and counterweight retention detection system which comprises a first steel wire rope, one end of the first steel wire rope is fixedly connected with a second steel wire rope, one side of the first steel wire rope is slidably connected with a first pulley, the bottom of the first pulley is fixedly connected with an elevator car, and one side of the second steel wire rope is slidably connected with a second pulley. The bottom of the second pulley is fixedly connected with a counterweight, the other side of the first steel wire rope and the other side of the second steel wire rope are fixedly connected with photoelectric switches, and one end of each photoelectric switch is connected with a light isolation plate in a clamped mode. According to the elevator car and counterweight retention detection system, when the elevator car or counterweight retention occurs, the working condition is detected in time, and the situation that when the lift car is detained, the elevator traction machine still rotates, the other part of the counterweight (or the lift car) of the traction system continues to be lifted, and consequently the counterweight (or the lift car) falls or a steel wire rope is disengaged from a groove is avoided.
本发明公开了一种电梯轿厢与对重滞留检测系统,包括第一钢丝绳,第一钢丝绳的一端固定连接有第二钢丝绳,第一钢丝绳的一侧滑动连接有第一滑轮,第一滑轮的底部固定连接有电梯轿厢,第二钢丝绳的一侧滑动连接有第二滑轮,第二滑轮的底部固定连接有对重,第一钢丝绳的另一侧和第二钢丝绳的另一侧均固定连接有光电开关,两个光电开关的一端均卡合连接有隔光板,本发明一种电梯轿厢与对重滞留检测系统,能在电梯在发生轿厢或对重发生滞留时,及时检测出此工况,避免出现轿厢滞留时,电梯曳引机仍然在转动,会使曳引系统的另一部分对重(或轿厢)继续提升,造成对重(或轿厢)坠落或钢丝绳脱槽等情况的发生。
