Description

Technical Field

[0001] This utility model relates to the field of elevator safety technology, specifically to an automatic detection device for preventing elevator landing doors from derailing. Background Technology

[0002] Elevators are indispensable vertical transportation equipment in modern buildings. They serve different floors of a building by vertically moving a car within a rigid track. Modern elevators typically use permanent magnet synchronous traction machines as their power source, which have advantages such as low energy consumption, high operating efficiency, and fast lifting speed. This not only saves machine room space but also promotes the rapid development of super high-rise buildings.

[0003] The safe operation of an elevator relies on two core structural elements: the car and the landing doors. The car, as the unit carrying passengers or goods, is typically designed to be robust and highly stable; while the landing doors (i.e., the elevator exterior doors), serving as entrances and exits to each floor, are equally crucial for safety. Landing doors are usually connected to the sill via sliding rails. During frequent opening and closing, they are prone to derailment or deformation due to long-term wear, external impacts (such as human impact or leaning), or installation misalignment. Once a landing door derails, it can range from affecting normal elevator operation to causing serious accidents such as door collapse, posing a significant safety hazard to passengers and surrounding personnel. Current technology has limitations in effectively detecting and alarming elevator derailments.

[0004] Therefore, an automatic detection device for preventing elevator landing doors from derailing is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic detection device for preventing elevator landing doors from derailing, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] An automatic detection device for preventing elevator landing doors from derailing includes a sill, an elevator landing door panel slidably connected to the inner wall of the sill, an installation groove extending through the bottom end of the elevator landing door panel, an installation shell disposed inside the installation groove, a detection component mounted on the surface of the installation shell, and a docking component and a locking component for limiting the position of the installation shell mounted on the inner wall of the installation groove.

[0008] Furthermore, the docking assembly includes an I-shaped fixing seat, which is fixedly connected to the inner wall of the mounting groove. A protrusion is fixedly connected to the top surface of the mounting shell, and the protrusion is movably inserted into the inner wall of the slot.

[0009] Furthermore, the locking assembly includes a mounting cavity, which is located inside the front side of the I-shaped fixing seat. A double-ended screw is rotatably connected to the inner wall of the mounting cavity, and a knob is fixedly connected to the end of the double-ended screw. A connecting rod is threadedly connected to the surface of the double-ended screw. A sliding groove is provided through the rear side of the mounting cavity, and the inner wall of the sliding groove is slidably connected to the surface of the connecting rod. A pin is fixedly connected to the surface of the connecting rod, and the pin is movably inserted into the I-shaped fixing seat. An insertion hole is provided on the surface of the protrusion, and the inner wall of the insertion hole is movably inserted into the end of the pin.

[0010] Furthermore, the detection component includes a sliding column, which is movably inserted into the surface of the mounting housing. A mounting base is fixedly connected to one end of the sliding column, and a ball bearing is rotatably connected to the surface of the mounting base. The ball bearing is in rolling contact with the inner wall of the mounting housing. A connecting plate is fixedly connected to the other end of the sliding column, and a spring is fixedly connected between the connecting plate and the inner wall of the sill. A pressure sensor is fixedly connected to the inner wall of the mounting housing, and a buzzer is fixedly installed on the front of the mounting housing.

[0011] Furthermore, a guide rod is fixedly connected to the inner wall of the mounting shell, and the guide rod is slidably connected to the connecting plate.

[0012] Furthermore, the number of mounting slots and detection components are both two sets.

[0013] The beneficial effects of this utility model are as follows:

[0014] Under normal operating conditions, the elevator landing door panel slides along the inner wall of the sill. When the elevator landing door panel accidentally derails, the detection component will immediately detect it and issue an alarm. By releasing the limit on the mounting shell through the docking component and locking component, the mounting shell and detection component can be quickly disassembled, facilitating the inspection and maintenance of the detection component. In use, it effectively detects and alarms the elevator landing door derailment, thereby ensuring the safety of the elevator landing door and enabling quick disassembly of the device, making inspection and maintenance very convenient.

[0026] like Figures 1 to 5As shown, an automatic anti-derailment detection device for elevator landing doors includes a sill 1, an elevator landing door panel 2 slidably connected to the inner wall of the sill 1, a mounting groove 3 extending through the bottom end of the elevator landing door panel 2, a mounting shell 4 disposed inside the mounting groove 3, a detection component 7 mounted on the surface of the mounting shell 4, and a docking component 5 and a locking component 6 for limiting the mounting shell 4 mounted on the inner wall of the mounting groove 3. More specifically, under normal operating conditions, the elevator landing door panel 2 slides along the inner wall of the sill 1. When the elevator landing door panel 2 accidentally derails, the detection component 7 will immediately detect it and issue an alarm. By releasing the limitation on the mounting shell 4 through the docking component 5 and the locking component 6, the mounting shell 4 and the detection component 7 can be quickly disassembled, facilitating the inspection and maintenance of the detection component 7.

[0027] The docking assembly 5 includes an I-shaped fixing base 501, which is fixedly connected to the inner wall of the mounting groove 3. A protrusion 503 is fixedly connected to the top surface of the mounting shell 4, and the protrusion 503 is movably inserted into the inner wall of the slot 502. It should be noted that the mounting shell 4 can be installed in a designated position through the cooperation of the slot 502 and the protrusion 503, and the I-shaped fixing base 501 can be fixed to the inner wall of the mounting groove 3 using bolts.

[0028] The locking assembly 6 includes a mounting cavity 601, which is located inside the front side of the I-shaped fixing base 501. A double-ended screw 602 is rotatably connected to the inner wall of the mounting cavity 601. A knob 603 is fixedly connected to the end of the double-ended screw 602. A connecting rod 604 is threadedly connected to the surface of the double-ended screw 602. A sliding groove 605 is provided through the rear side of the mounting cavity 601. The inner wall of the sliding groove 605 is slidably connected to the surface of the connecting rod 604. A pin 606 is fixedly connected to the surface of the connecting rod 604. The pin 606 is movably inserted into the I-shaped fixing base 501. An insertion hole 607 is provided on the surface of the protrusion 503. The inner wall of the insertion hole 607 is movably inserted into the end of the pin 606. More specifically, by rotating the knob 603, the double-ended screw 602 is rotated, and under the action of the thread, the connecting rod 604 can slide along the inner wall of the slide groove 605, thereby moving the insertion post 606. This causes the insertion post 606 to disengage from the inner wall of the insertion hole 607, thus releasing the restriction on the mounting shell 4. By pulling the mounting shell 4 downward, the mounting shell 4 and the detection component 7 can be disassembled, thereby facilitating the inspection and maintenance of the detection component 7.

[0029] The detection component 7 includes a sliding column 701, which is movably inserted into the surface of the mounting housing 4. A mounting base 702 is fixedly connected to one end of the sliding column 701. A ball bearing 703 is rotatably connected to the surface of the mounting base 702 and is in rolling connection with the inner wall of the mounting housing 4. A connecting plate 704 is fixedly connected to the other end of the sliding column 701. A spring 708 is fixedly connected between the connecting plate 704 and the inner wall of the sill 1. A pressure sensor 705 is fixedly connected to the inner wall of the mounting housing 4. A buzzer 707 is fixedly installed on the front of the mounting housing 4. It should be noted that during the movement of the elevator landing door panel 2, the mounting shell 4 will move, which in turn will cause the ball bearing 703 to roll along the inner wall of the sill 1. The spring 708 is in a stretched state, and the sliding column 701 and the connecting plate 704 will remain stable. The pressure detected by the pressure sensor 705 will remain stable. When the elevator landing door panel 2 derails, the ball bearing 703 will no longer be blocked by the sill 1. Under the elastic force of the spring 708, it will push the connecting plate 704 to move, so that the connecting plate 704 contacts the detection end of the pressure sensor 705. The pressure sensor 705 will detect the pressure, and at this time the buzzer 707 will sound an alarm.

[0030] A guide rod 706 is fixedly connected to the inner wall of the mounting shell 4, and the guide rod 706 is slidably connected to the connecting plate 704. More specifically, by setting the guide rod 706, the connecting plate 704 is reinforced and supported, making the connecting plate 704 more stable during sliding.

[0031] There are two sets of mounting slots 3 and two sets of detection components 7. It should be noted that by setting two sets of mounting slots 3 and detection components 7, derailment can be detected at two locations, thus ensuring the accuracy of the detection results.

[0032] In summary: Under normal operating conditions, the elevator landing door panel 2 will slide along the inner wall of the sill 1. When the elevator landing door panel 2 unexpectedly derails, the detection component 7 will immediately detect it and issue an alarm. By releasing the limit on the mounting shell 4 through the docking component 5 and the locking component 6, the mounting shell 4 and the detection component 7 can be quickly disassembled, facilitating the inspection and maintenance of the detection component 7. In use, it effectively detects and alarms the elevator landing door derailment, thereby ensuring the safety of the elevator landing door. Furthermore, the device can be quickly disassembled, making inspection and maintenance very convenient.
