Description

Technical Field

[0001] The utility model relates to the field of elevators, in particular to an elevator hall door with a self-cleaning function. Background Art

[0002] As an up and down passage in high-rise buildings, elevators are indispensable building facilities in high-rise buildings. During the construction of elevators, corresponding elevator hall doors need to be installed on each floor of the building to serve as entrances and exits for up and down passages to ensure the safety of pedestrians. As shown in the elevator hall door structure disclosed on the China Patent Network (public announcement number CN212608949U), this type of elevator hall door has a brush assembly with a brush body provided at the lower part of the hall door during its daily opening and closing process. The brush assembly plays a brushing and cleaning role as the hall door reciprocates, sweeping garbage in the track groove out of the track groove through the garbage hole to ensure the normal operation of the elevator hall door.

[0003] However, the elevator hall doors used in the aforementioned patents and in the current market still have some shortcomings: the existing method of installing a cleaning brush under the elevator hall door to brush the track groove has a relatively limited cleaning capacity and is not efficient in cleaning garbage in the track groove. It is very easy for garbage to remain in dead corners, and long-term accumulation leads to adhesion, which is not conducive to the stable opening and closing of the elevator hall door. To this end, those skilled in the art have provided an elevator hall door with a self-cleaning function to solve the problems raised in the above background technology. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present invention provides an elevator hall door with a self-cleaning function, which solves the problem of relatively low self-cleaning ability of the existing elevator hall door raised in the above background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an elevator hall door with a self-cleaning function, comprising a brake frame and a guide rail frame that are horizontally opposed;

[0006] Two sets of elevator door panels are symmetrically installed between the brake frame and the guide rail frame;

[0007] The bracket back plate of the brake frame is equipped with a brake mechanism for driving the elevator door panels to slide towards each other;

[0008] The bottom plate of the elevator door panel is provided with a supporting guide wheel guided by the guide rail frame, and the plate frame of the elevator door panel is provided with an air blowing cleaning mechanism for blowing the guide rail frame;

[0009] The air blowing cleaning mechanism includes a bottom support frame and a top support frame which are installed in a horizontally opposite form inside the elevator door panel. A compression bellows is installed above the bracket of the bottom support frame, and a cleaning air duct is installed on the bottom of the compression bellows horizontally opposite to the guide rail frame. The two ends of the bracket of the top support frame are symmetrically connected with a lifting guide rod connected to the compression bellows, and the two sides of the box body of the compression bellows are symmetrically connected with a stretching guide rod opposite to the support guide wheel.

[0010] As a further technical solution of the present invention: the support guide wheel is a double guide wheel structure, and a winding disk is installed between the two groups of guide wheels of the support guide wheel, and the winding disk is wound with a winding rope connected to the stretching guide rod.

[0011] As a further technical solution of the present invention: the compression bellows is an accordion box structure.

[0012] As a further technical solution of the present invention: a compression spring is sleeved on the outer side of the arm of the lifting guide rod and is pressed against the top support frame.

[0013] As a further technical solution of the present invention: the braking mechanism includes pulleys symmetrically installed at both ends of the brake frame bracket and two groups of brake slides symmetrically slidably connected to the brake frame, and a brake rope connected to the brake slide is connected between the two opposite groups of pulleys. The bottom rope of the brake rope is provided with a first fixed seat connected to one group of brake slides, and the top rope of the brake rope is provided with a second fixed seat connected to the other group of brake slides.

[0014] As a further technical solution of the present invention: a brake motor opposite to the pulley is installed at one end of the bracket of the brake frame, and the brake motor and the pulley are connected through a transmission belt.

[0015] The utility model provides an elevator hall door with a self-cleaning function, which has the following beneficial effects compared with the prior art:

[0016] The elevator hall door of this design uses a braking mechanism as a power source to drive the relative elevator door panels to open and close along the guide rail frame during daily opening and closing. At the same time, the elevator door panels open and close, and push the bottom support guide wheel to rotate along the guide rail frame, driving the combined operation of the reel and the reel rope. Then, when the elevator door panels are closed, the reel rope is used to stretch and compress the compression bellows in the air blowing cleaning mechanism, and the gas inside the compression bellows is pressed out through the cleaning air duct, so that the dust falling into the guide rail frame is cleaned by air without dead angles. Moreover, when the elevator door panels are opened and closed, the compression bellows is retracted and reset to accumulate air again for the next air blowing cleaning. It has a good circulating self-cleaning function, which can improve the self-cleaning ability of the elevator hall door and ensure the operational stability of the elevator hall door.

A brake motor 19 opposite to the pulley 15 is installed at one end of the bracket of the brake frame 1, and the brake motor 19 and the pulley 15 are connected through a transmission belt 20. By controlling the combined rotation of the brake motor 19 and the transmission belt 20, the combined operation of the pulley 15 and the brake rope 16 is driven. The opposite movement of the first fixed seat 17 and the second fixed seat 18 on the brake rope 16 is utilized to push the two relative groups of brake slides 4 to move in opposite directions along the brake frame 1 as a braking source, pushing the relative elevator door panels 3 to open and close, as the entrance and exit of the elevator.

[0024] The bottom plate of the elevator door panel 3 is provided with a supporting guide wheel 12 guided by the guide rail frame 2, and the plate frame of the elevator door panel 3 is provided with an air blowing cleaning mechanism for blowing the guide rail frame 2. The air blowing cleaning mechanism includes a bottom support frame 5 and a top support frame 7 installed in a horizontally opposite form inside the elevator door panel 3. A compression bellows 6 is installed above the bracket of the bottom support frame 5, and a cleaning air duct 8 horizontally opposite to the guide rail frame 2 is installed on the bottom of the compression bellows 6. The supporting guide wheel 12 is a double guide wheel structure, and a winding disk 13 is installed between the two sets of guide wheels of the supporting guide wheel 12. The winding disk 13 winds A winding rope 14 connected to the stretching guide rod 11 is connected. When the support guide wheel 12 slides along the support guide of the guide rail frame 2, the winding drum 13 is driven to rotate synchronously. By utilizing the rotation of the winding drum 13, when the elevator door panel 3 is closed, the winding rope 14 is wound by the winding drum 13.
