Description
Technical Field
[0001] The utility model belongs to the technical field of elevator doors, and more specifically, particularly relates to a door lock circuit safety protection device. Background Art
[0002] The elevator door lock circuit is an important part of the elevator safety measures and the basic guarantee for the operation of the elevator. If there is a loophole in this part, it will often lead to safety accidents. In recent years, due to the increase in the number of elevators and the increase in maintenance work, the elevator maintenance personnel have neglected the inspection of safety hazards. When the elevator fails, the hidden dangers of the safety circuit lead to the expansion of the fault, thus causing the accident.
[0003] For example, a Chinese patent with publication number CN214935095U discloses an elevator door lock circuit safety protection device including an elevator door assembly, a hook monitoring assembly and a mobile unhooking assembly; the elevator door assembly includes a fixed plate, the front side of the fixed plate is movably connected with a sliding plate symmetrically distributed, the lower side of the sliding plate is fixedly connected with an elevator door, and the front side of the sliding plate located on the right side is fixedly connected with a fixed block, the fixed block is movably connected to the first hook through an electrically controlled rotating shaft, a second hook is provided at the lower side of the first hook, and the second hook is fixedly connected to the fixed plate through a mobile unhooking assembly; the hook monitoring assembly includes a moving block, the left end of the first hook is fixedly connected to a slide rail plate symmetrically distributed up and down, the slide rail plate is slidably connected to the connecting plate through a sliding connection block, one end of the connecting plate is fixedly connected to the moving block, the other end of the connecting plate is fixedly connected to the outer side of the indicating block, a spring is provided on the outer side of the indicating block, one end of the spring is fixedly connected to the connecting plate, the other end of the spring is fixedly connected to the positioning plate, one end of the positioning plate is fixedly connected to the first hook, and the inner side of the positioning plate is fixedly connected to a position sensor;
[0004] The technical solution recorded in this scheme is through setting up a hook monitoring component. When the first hook moves to the upper position of the second hook, the second hook contacts the moving block, and the moving block moves toward the inside of the first hook. The movement of the moving block drives the connecting plate to slide and move in the slide rail plate through the sliding connecting block, and the indicator block moves at the same time. When the indicator block moves, the position sensor senses and sends a signal. When the position sensor does not sense the preset position of the indicator block, the controller receives the signal and controls the warning light to flash. This setting can monitor the hooking status of the first hook and the second hook in real time to prevent the first hook and the second hook from not being hooked together due to damage to the electric control shaft, thereby improving the safety of the elevator door. However, when this scheme is in use, the position of the first hook cannot be adjusted, which requires the first hook and the second hook to be assembled together during assembly. The assembly accuracy requirements are high, which affects the assembly efficiency.
[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a door lock circuit safety protection device is provided to achieve a more practical purpose. Utility Model Content
