The invention discloses a device for controlling sudden stop of an elevator. The device comprises an expansion pipe, a control box for controlling expansion of the expansion pipe and a storage cavityfor supplying air to the expansion pipe. A control cavity is formed in the control box, and compressed gas is stored in the storage cavity; a communicating cavity and an air outlet pipe are arranged in the control box, one end of the communicating cavity is connected with the storage cavity, the other end is connected with the air outlet pipe, and the air outlet pipe penetrates through the controlbox, extends out of the control box and is connected with the expansion pipe through an air pipe; and a cut-off mechanism for cutting off a connecting cavity is arranged in the connecting cavity. Theexpansion pipe is connected to a pet rope or a chain, when an elevator door clamps the expansion pipe, the cut-off mechanism does not cut off the connecting cavity again, gas in the storage cavity enters the expansion pipe, the expansion pipe expands, a door is pushed towards the two sides after expansion, and therefore after an elevator system detects that the elevator door is pulled by large force, the elevator is controlled to stop immediately; and therefore, the elevator does not continue to run any more, the pet rope or chain cannot be pulled, a pet cannot be hurt, and meanwhile the elevator can be protected.
本发明公开了控制电梯骤停的装置,包括膨胀管、控制膨胀管膨胀的控制箱和为膨胀管供气的存储腔。控制箱内设控制腔,存储腔存储有压缩气体;控制箱内还设有连通腔和出气管,连通腔一端与存储腔连接,另一端与出气管连接,出气管贯穿控制箱并延伸到控制箱外,出气管与膨胀管通过气管连接;连接腔内设有截断连接腔的截断机构。把膨胀管连接在宠物绳或链条上,当电梯门夹住本膨胀管时,截断机构不再截断连接腔,存储腔内的气体进入膨胀管内,使得膨胀管膨胀,膨胀后把门向两侧推,这样电梯系统检测到电梯门受到扳动的大力后,就会控制电梯立刻停下,这样电梯就不再继续运行,就不会拉扯宠物绳或链条,就不会对宠物造成伤害,同时也可以保护电梯。
