Embodiment Construction

[0029] The electromechanical interlocking device of the protective door of the present invention will be further described with reference to the accompanying drawings.

[0030] Such as figure 1 , Figure 5 , Image 6 As shown, the working principle of the protective door electromechanical interlocking device provided by the present invention is: when the hoisting cage runs to within the set leveling error, the bumper arranged at the bottom of the hoisting cage triggers the contacts arranged on the guide rail on the travel switch I7 , The contact is set to conduct and the operator touches the door open button 5 to set it in place. The contact, the door open button 5, and the electromagnetic lock 6 are connected in series, so the electromagnetic can only be activated when the contact and the door open button 5 are both set. When the lock 6 is energized and opened, the electromagnetic lock 6 has to be opened and then the protective door 1 is released, and then the protective door 1 ...

Abstract

The invention relates to hoisting machinery, in particular to a protective door electromechanical interlocking device. A protective door electromechanical interlocking device in the prior art is complex in structure and single in door opening mode of protective doors, cannot meet the requirement for double purposes for carrying both people and goods in GB26557-2011 'cage with vertically-guiding construction lift with double purposes of carrying people and goods'. The protective door electromechanical interlocking device meets the requirement in the standard of the GB26557-2011 'cage with vertically-guiding construction lift for carrying people and goods'; the flat layer of the cage is high in precision; the door opening mode of the protective doors is flexible; the protective door electromechanical interlocking device is simple in structure and low in manufacturing cost; safety performance of a lift is improved; the independent mechanical lock is arranged on each protective door, the mechanical locks are simple in structure and low in manufacturing cost, after the protective doors are closed, each protective door is locked through each mechanical lock, therefore, the protective doors are prevented from being opened accidentally, the locking effect of the protective doors is good, and safety performance of the lift is improved.

Description

Technical field [0001] The invention relates to a hoisting machine, in particular to an electromechanical interlocking device for a protective door. Background technique [0002] The elevator is an indispensable mechanical equipment in the construction of modern high-rise buildings. Its main function is to transport the building materials on the ground to the high-rise construction site. The transportation efficiency of the elevator directly affects the progress of the project, especially the cage of the elevator, as a elevator The main transportation structure is responsible for transporting materials. The elevator should be able to meet the requirements of construction safety while ensuring efficiency. The protective door of the elevator cage is not allowed to be opened casually during the transportation of materials. For this reason, the designer Various interlocking devices are designed for the protective door of the elevator. [0003] The patent number CN03272446.2 discloses ...
