[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a technical solution:

[0025] Please see Figures 1 to 3 A heavy-duty two-piece top-opening door operator includes a door panel assembly 1 installed in an elevator shaft, a support rail 2 slidably connected to the outside of the door panel assembly 1, a lifting assembly 3 installed on the top of the door panel assembly 1, and a cleaning assembly 4 for cleaning the support rail 2 installed between the door panel assembly 1 and the support rail 2.

[0026] The cleaning component 4 includes two sets of cleaning sliders 402. The cleaning sliders 402 are slidably installed on the inner side of the support rail 2. A hollow plate 403 is fixed to the side of the cleaning slider 402 near the support rail 2. The surface of the hollow plate 403 has multiple air inlets 405. Cleaning bristles 406 are fixed on the hollow plate 403 on the left and right sides of the air inlets 405. An air pipe 404 is fixed to one end of the hollow plate 403 and passes through the end face of the cleaning slider 402. An air pump (not shown in the figure) is fixed to the end of the air pipe 404. The air pump can pump air out from the air inlets 405 on the hollow plate 403, thereby playing a role in dust collection. The air pipe 404 is connected to the hollow plate 403.

[0027] The door panel assembly 1 includes a door panel body 101. A connecting slider 104 is provided at the connection between the door panel body 101 and the support rail 2. A dust cover 103 is fitted over the connecting slider 104. The dust cover 103, the cleaning slider 402, and the connecting slider 104 form a semi-enclosed structure. The dust cover 103 is fixed to the left and right sides of the door panel body 101. A connector 102 is fixed to the top of the door panel body 101. A support rod 401 is fixedly connected between the cleaning slider 402 and the connecting slider 104. The dust cover 103 covers the outside of the cleaning slider 402 and the connecting slider 104, which can prevent a large amount of dust from entering between the cleaning slider 402 and the connecting slider 104.

[0028] By adopting the above technical solution, when the connecting slider 104 on the door panel body 101 slides inside the support rail 2, the cleaning slider 402 can be driven to slide synchronously through the support rod 401. Since the cleaning slider 402 is equipped with cleaning bristles 406, when the cleaning bristles 406 move, they can clean the dust inside the support rail 2, preventing stubborn stains from getting stuck inside the support rail 2 and affecting the normal use of the connecting slider 104. At the same time, after the cleaning bristles 406 brush off the dust, the air pump can be started, and the air pump will pump air out through the air inlet 405 on the hollow plate 403, thereby playing a role in dust suction. The dust can enter the hollow plate 403 and work with the cleaning bristles 406 to clean the dust inside the support rail 2, thereby further preventing the door panel body 101 from getting stuck with the support rail 2 and affecting the normal movement of the door panel body 101.

[0029] Specifically, such as Figure 2 As shown, a connector 102 is fixed to the top of the door panel body 101. A support rod 401 is fixedly connected between the cleaning slider 402 and the connecting slider 104. The lifting assembly 3 includes a fixing member 301 fixedly connected to the connector 102 by screws. A lifting chain 302 is fixedly connected to one end of the fixing member 301. A lifting sprocket 304 is engaged with the other end of the lifting chain 302. The lifting sprocket 304 is rotatably installed in the elevator shaft. A guide wheel 303 is also installed in the elevator shaft. The guide wheel 303 is in contact with the lifting chain 302.

[0030] By adopting the above technical solution, the drive motor can drive the lifting sprocket 304 to rotate through the gear set, and the lifting sprocket 304 can drive the lifting chain 302 to move, thereby pulling the door panel body 101 to slide inside the support guide rail 2 through the lifting chain 302 to realize the upward opening of the door. The guide wheel 303 plays a guiding and limiting role for the lifting chain 302. The guide wheel 303 can also be a transmission sprocket to guide the lifting sprocket 304. For the detailed working principle of the lifting component 3, please refer to the existing public technical solution (CN203754189U), which will not be elaborated here.

[0031] Working principle: The drive motor drives the lifting sprocket 304 to rotate through the gear set. The lifting sprocket 304 drives the lifting chain 302 to rewind, thereby pulling the door panel body 101 to slide inside the support rail 2, realizing the upward opening of the door. The guide wheel 303 guides and limits the lifting chain 302. When the connecting slider 104 on the door panel body 101 slides inside the support rail 2, it can drive the cleaning slider 402 to slide synchronously through the support rod 401. Since the cleaning slider 402 is equipped with cleaning bristles 406, the cleaning bristles 406... During movement, the cleaning brush 406 can clean the dust inside the support rail 2, preventing stubborn stains from getting stuck inside the support rail 2 and affecting the normal use of the connecting slider 104. After the cleaning brush 406 brushes away the dust, the air pump can be activated to pump air out through the air inlet 405 on the hollow plate 403, thereby playing a dust suction role. The dust can enter the hollow plate 403 and work with the cleaning brush 406 to clean the dust inside the support rail 2, thereby further preventing the door panel body 101 from getting stuck with the support rail 2 and affecting the normal movement of the door panel body 101.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
