Description

Technical Field

[0001] This utility model relates to the field of elevator cleaning technology, and in particular to an elevator door track cleaning and maintenance device. Background Technology

[0002] Elevator door tracks are guiding devices used to move elevator doors. An elevator door track system consists of guide rails and guiding devices. The guide rails are typically located on either side, above, or below the elevator door opening, while the door slides along the guide rails via the guiding devices, maintaining a stable trajectory. It is a crucial component of the elevator door system, ensuring the smooth and safe opening and closing of the elevator doors. Over time, a large amount of impurities and dust accumulates in both the upper and lower tracks. Manual cleaning is time-consuming and labor-intensive, and the upper track, being higher, is difficult to clean.

[0003] Chinese patent discloses a passenger elevator door track wear detection device (authorization announcement number CN217033463U). The patented technology mainly includes a driving device, which includes two upright plates. The two upright plates are respectively fixedly connected to the upper end face of two fixed plates. A lead screw is rotatably connected between the two upright plates. A motor is installed on the left side wall of the left column. Starting the first cylinder can drive the bottom simulated pulley to move downward.

[0004] However, this patent still has shortcomings. Over time, a large amount of impurities and dust accumulate in both the upper and lower tracks of the elevator door. Manual cleaning is time-consuming and labor-intensive, and the upper track is also inconvenient to clean due to its height. Therefore, those skilled in the art have provided an elevator door track cleaning and maintenance device to solve the problems mentioned in the background art. Utility Model Content

A threaded rod is fixed at the bottom end of the drive shaft of the motor. The bottom end of the threaded rod passes through the threaded hole and is threadedly connected.

[0019] Specifically, the motor has a drive shaft that fixes the threaded rod, providing power for the rotation of the threaded rod. This allows the connecting block, connecting frame, and rollers to move up and down as needed, so that the upper roller can fit against the lower surface of the upper track and the lower roller can fit against the upper surface of the lower track. Pushing the long plate allows the rollers to rotate, and the brush can move as needed, facilitating cleaning of different positions on the lower and upper track grooves.

[0020] Furthermore, the lower track is vertically aligned with the center of the upper track, the lower track is vertically aligned with the center of the turntable, and the upper track is vertically aligned with the center of the turntable.

[0021] Specifically, the lower track, upper track, and turntable are vertically aligned to facilitate the brushes reaching into the lower and upper track grooves for cleaning.

[0022] Furthermore, the rear end of the fixing plate is provided with a second circular hole, and a second motor is fixed to the rear end of the fixing plate. The front end of the transmission shaft of the second motor extends into the second circular hole, and a rotating rod is fixed to the front end of the transmission shaft of the second motor.

[0023] Specifically, the second motor has a drive shaft that fixes the rotating rod, providing power for the rotation of the rotating rod and the turntable. At the same time, the brush can rotate to clean the lower and upper rail grooves.

[0024] 2. Beneficial effects

[0025] Compared with existing technologies, the advantages of this utility model are:

[0026] This utility model adds a movable component to the track assembly. When cleaning and maintenance of the elevator door track is required, the turntable is inserted into the installation groove, and the motor is started to make the threaded rod rotate. The connecting block, connecting frame and roller can be moved as needed, so that the upper roller is in contact with the lower surface of the upper track and the lower roller is in contact with the upper surface of the lower track, which facilitates cleaning and maintenance of the lower track and upper track at different heights.

[0027] At the same time, a cleaning component is added. When cleaning and maintenance of the elevator door track is required, push the long plate to make the rollers rotate, and the brush can be moved as needed. Then start the second motor so that the turntable and brush can rotate as needed. The brush can clean and maintain different positions of the lower and upper rail tracks, saving time and effort and improving work efficiency.
