Linkage opening and closing system of automatic door of construction elevator and control method of linkage opening and closing system

Abstract

The invention discloses a linkage opening and closing system of an automatic door of a construction elevator and a control method of the linkage opening and closing system. The linkage opening and closing system of the automatic door of the construction elevator comprises a cage door, wherein a bottom cage door is movably mounted on one side of the cage door; and a door driving motor is fixedly mounted in the cage door. A regulating and controlling assembly is movably mounted between the cage door and the bottom cage door, when an interlocking motor receives an instruction of a sub-control system, the interlocking motor drives a self-locking device to drive an interlocking hook, thus, the interlocking hook completely wraps an interlocking transverse rod seat, meanwhile, when the interlocking device is closed in place, a detection switch can detect whether the interlocking hook completely wraps the interlocking transverse rod seat or not, then a sub-control box controls the door driving motor to control opening and closing of the automatic door, finally, after the automatic door is closed, the interlocking motor releases the self-locking hook, thus, the interlocking hook returns to an opening state under the effect of a torsional spring, the interlocking hook on the cage door is separated from the interlocking transverse rod seat on the bottom cage door, and it ensures that a cage can normally leave an interlocking mechanism and move upwards.

Description

technical field [0001] The invention relates to the technical field of construction hoist equipment, in particular to a linkage switch system of an automatic door of a construction hoist and a control method thereof. Background technique [0002] The automatic door is one of the key technologies of construction elevators. The linkage switch and control method of its automatic switch directly affect the safety and convenience of personnel entering and exiting. The automatic door mainly receives signals from the main control system, and then the cage door drive module drives the cage door to rise. , the interlock device pops up immediately after the cage door rises, driving the bottom cage door to rise together. After the cage door triggers the upper limit, the cage door stops running. When the cage door drive module drives the cage door to run downward, the bottom cage The door relies on its own weight to run downwards with the cage, the cage door triggers the lower limit swi...

AI Technical Summary

Problems solved by technology

[0003] In the actual use of the linkage switch mode and control method of the traditional automatic door of the construction hoist, only the cage door is considered to drive the bottom cage door to rise, and when the cage door is lowered, the bottom cage door falls together with the cage door by its own weight The interlock mechanism is not completely locked, but only in normal contact, resulting in the risk of detachment between the bottom cage door and the hanging cage door. At the same time, there is no detection method for the automatic door running up and down, which may also cause the hanging cage door to malfunction during operation, resulting in safety accidents , the overall safety and reliability need to be improved
