Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a closed-door foreign body detection and processing structure for an elevator. Background Art

[0002] Elevator refers to a permanent transportation device that serves several specific floors in a building and whose car runs on at least two rows of rigid rails that are perpendicular to the horizontal plane or inclined at an angle of less than 15° to the plumb line;

[0003] In the actual use of the existing elevator car, in order to avoid the situation of foreign objects being clamped and injured when closing the door, infrared transmitters and infrared receivers are installed in the door bodies on both sides of the elevator car, so that the elevator door stops closing when foreign objects are present through infrared sensing and elevator control mechanism. However, in actual use, when there are many impurities adhering to the surface of the infrared transmitter and infrared sensor, foreign objects may be detected, resulting in the elevator door being unable to close, thus affecting the normal use of the elevator. Therefore, we propose a foreign object detection and processing structure for elevator door closing. Utility Model Content

[0008] By adopting the above technical solution, the bristles are attached to the surface of the infrared transmitter and the infrared receiver, so that the bristles can be used to clean the infrared transmitter and the infrared receiver during the lifting process. After long-term use, when the bristles are damaged and the effect of cleaning foreign objects decreases, rotating the adjusting bolt can drive the movable block to move and adjust, so that the bristles can fit the infrared transmitter and the infrared receiver again, thereby ensuring the cleaning effect, and the adjustment operation is convenient and quick.

[0009] As a preferred embodiment of the utility model, limiting rods are fixed on both sides of one side wall of the movable plate, and limiting holes are provided on one side wall of the movable block corresponding to the limiting rods, and the limiting rods are inserted into the limiting holes.

[0010] By adopting the above technical solution, when the rotating adjusting bolt drives the movable block to adjust the position, the limiting rod can be used for limiting the position, thereby ensuring high movement stability of the movable block.

[0012] By adopting the above technical solution, the first magnet block can be separated from the second magnet block by pulling the movable plate forcefully, so that the movable plate and the movable block can be easily disassembled, and the excessively worn bristles can be easily disassembled and replaced.

[0013] As a preferred embodiment of the present utility model, the end of the adjusting bolt is provided with a hexagonal groove.

[0014] By adopting the above technical solution and the provision of the hexagonal groove, it is convenient to operate the adjusting bolt with the aid of a tool.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0030] like Figure 1 and 2 As shown; the cleaning mechanism 2 includes a fixed block 21, a side wall of the fixed block 21 and a corresponding screw slider 33 are fixedly connected, an outer wall of the fixed block 21 is connected to a movable plate 22, a through hole is provided on the surface of the fixed block 21 and a movable block 23 is passed through the through hole, a brush bristle is detachably fixed to the outer wall of the movable block 23, a groove 24 is provided on the outer wall of the movable plate 22, an adjusting bolt 25 is movably passed through the groove 24, a threaded hole is provided on one side wall of the movable block 23, the adjusting bolt 25 is inserted into the threaded hole and the thread is engaged;
