Description

Technical Field

[0001] This invention relates to the field of elevators, and more specifically, to an elevator ground track cleaning mechanism. Background Technology

[0002] Elevator doors are a very important part of an elevator. There are two doors: the one that can be seen from the outside of the elevator and is fixed to each floor is called the hall door, and the one that can be seen from the inside of the elevator and is fixed to the car and moves with the car is called the car door. The elevator doors are generally opened and closed by the car door driving the hall door.

[0003] During actual use of elevator doors, dust particles adhere to the soles of passengers' shoes. When passengers step on the elevator door track, these dust particles fall into the track groove. The dust particles in the track groove obstruct the movement of the elevator door, causing it to move unsmoothly or even fail to close properly, creating a safety hazard. In addition, manual cleaning is cumbersome, requiring the elevator to be shut down and specialized cleaning tools to be used.

[0004] This application provides a dust removal mechanism installed inside an elevator door, which automatically cleans dust particles in the floor track groove as the elevator door moves, without the need for manual labor. Summary of the Invention

[0040] Please see Figure 1-11 In one embodiment of the present invention, an elevator floor rail cleaning mechanism includes a set of symmetrically arranged elevator doors 1 and a floor rail 2 slidably connected to the bottom of the elevator doors 1 and provided with a floor rail groove 201; a cleaning mechanism is installed on the lower part of the opposite abutting side of the elevator doors 1, the cleaning mechanism including a mounting box 3 nested in the elevator doors 1 and located above the floor rail 2, the mounting box 3 having a columnar cavity 306 whose lower part communicates with the floor rail groove 201, the rear end of the columnar cavity 306 being fixedly connected to a bucket block 4 nested in the floor rail groove 201 and whose front end face is arc-shaped, the columnar cavity 306... The mounting box 3 is equipped with a throwing wheel 5 that rotates through the ground rail groove 201. The throwing wheel 5 is connected to a follower wheel mechanism. The follower wheel mechanism includes a mounting shaft 6 that is fixedly connected to the throwing wheel 5 and rotatably connected to the mounting box 3. The mounting shaft 6 is connected to a roller shaft 8 through an acceleration transmission gear set 7. The roller shaft 8 is fixedly connected to a traveling wheel 9. The traveling wheel 9 abuts against the upper end face of the ground rail 2 located on both sides of the ground rail groove 201. The mounting box 3 is provided with a tangential cavity 307 that is tangentially connected to the cylindrical cavity 306. The rear end of the tangential cavity 307 is connected to a left cavity 302 for storing dust particles.

[0041] Specifically, during the closing process of elevator door 1, the traveling wheel 9 rolls on the ground rail 2, driving the roller shaft 8 to rotate. The roller shaft 8 drives the mounting shaft 6 and the throwing wheel 5 to rotate faster through the acceleration transmission gear set 7. The throwing wheel 5 cooperates with the bucket block 4 to push the dust particles that fall into the ground rail groove 201 into the columnar cavity 306. Under the action of centrifugal force, the dust particles enter the left cavity 302 along the inner wall of the columnar cavity 306 and the tangential cavity 307, realizing the cleaning and collection of dust particles in the ground rail groove 201, replacing manual cleaning. The ground rail groove 201 is cleaned and dust particles are collected every time the elevator door 1 closes, ensuring the cleanliness of the ground rail groove 201 and ensuring the normal closing of the elevator door 1, without the need for manual maintenance of the ground rail 2.

[0042] It should be noted that, for ease of description in this application, the opposite side of a set of elevator doors 1 is uniformly referred to as the front end.

[0043] In this embodiment, the elevator door 1 is provided with a mounting groove 101 with openings at the bottom and front.

[0044] Specifically, it facilitates the disassembly and removal of the dust cleaning mechanism in the installation box 3.

[0045] In this embodiment, the mounting box 3 is a hollow rectangular box. A longitudinal partition 301 is fixed inside the mounting box 3. The longitudinal partition 301 divides the inner cavity of the mounting box 3 into a left cavity 302 and a right cavity 303. A horizontal partition 304 is installed in the middle part of the right cavity 303. The horizontal partition 304 divides the right cavity 303 into two side cavities 305 with the same front and back. A columnar cavity 306 arranged in a longitudinal direction and a tangential cavity 307 tangentially connected to the columnar cavity 306 are opened in the horizontal partition 304. The front end of the columnar cavity 306 is connected to a feed opening 308 that extends to the front end face of the mounting box 3 and is connected to the ground rail groove 201.

[0046] In this embodiment, the outer end of the mounting shaft 6 extends into the side cavity 305, and the acceleration transmission gear set 7 is installed in the side cavity 305. The acceleration transmission gear set 7 includes an odd number of gears with gradually increasing gear radii from top to bottom. The uppermost gear of the acceleration transmission gear set 7 is fixedly connected to the mounting shaft 6, and the lowermost gear of the acceleration transmission gear set 7 is sleeved and fixed to the roller shaft 8. The gears in the middle part are rotatably connected to the inner wall of the side cavity 305 through a rotating shaft.

[0047] Specifically, by providing a multi-cavity mounting box 3, and through the sequentially connected feed opening 308, columnar cavity 306, tangential cavity 307, and left cavity 302, as well as the throwing wheel 5 set in the columnar cavity 306, the dust particles in the ground rail groove 201 are collected by rotation, which has a good cleaning and collection effect. At the same time, the structure is strong and easy to disassemble.

[0048] In this embodiment, the bucket block 4 slides against the inner wall of the ground rail groove 201, and the bucket block 4 is fixedly connected to the bottom plate of the mounting box 3 by bolts. The arc of the front end of the bucket block 4 is the same as the arc of the inner wall of the columnar cavity 306. The throwing wheel 5 includes multiple sets of throwing rods that are equidistantly distributed in a circle.

[0049] Specifically, the throwing rod and the bucket block 4 work together to achieve efficient throwing and collection of dust particles. The bucket block 4 serves as a friction component and is easy to replace.

[0050] In this embodiment, the traveling wheel 9 includes a wheel disc 902 fixedly connected to the roller shaft 8 and a wheel sleeve 901 sleeved on the wheel disc 902 and rotatably connected to the wheel disc 902. An annular cavity is formed between the wheel disc 902 and the wheel sleeve 901. A pawl 903 is hinged on the wheel disc 902 and nested in the annular cavity. The wheel sleeve 901 is annular and its inner wall is provided with a pawl groove 904 that cooperates with the pawl 903.

[0051] Specifically, when elevator door 1 is open, wheel sleeve 901 cannot drive wheel disk 902 to rotate, and therefore cannot drive throwing wheel 5 to rotate; when elevator door 1 is closed, wheel sleeve 901 drives wheel disk 902 to rotate, wheel disk 902 drives roller shaft 8 to rotate, and roller shaft 8 drives mounting shaft 6 and throwing wheel 5 to rotate faster through acceleration transmission gear set, so as to realize the rotation cleaning and collection of dust particles.

[0052] Please see Figure 8 and Figure 9 In another embodiment of the present invention, the dust removal mechanism further includes a quick-release assembly connected to and installed above the mounting box 3. The quick-release assembly includes a fixed insertion rail 11 fixedly connected to the elevator door 1. An insertion strip 13 that is laterally slidably connected to the fixed insertion rail 11 is nested inside the fixed insertion rail 11. A set of snap-fit ​​springs 14 that snap into the inner wall of the fixed insertion rail 11 are fixedly connected to the front end of the insertion strip 13.

[0053] Specifically, when disassembling the mounting box 3, the snap-fit ​​spring 14 is squeezed in the same direction, causing the snap-fit ​​spring 14 to move in opposite directions and disengage from the inner wall of the fixed insertion rail 11. Then, the snap-fit ​​spring 14 is pulled outward, causing the entire insertion strip 13 to disengage from the fixed insertion rail 11, thereby disassembling the mounting box 3 for easy installation and disassembly.

[0054] In this embodiment, the rear end of the mounting box 3 is connected to a collection drawer 10 nested in the left cavity 302.

[0055] Specifically, the mounting box 3 can be quickly removed using the quick-release assembly, and then the collection drawer 10 can be pulled out to quickly clean up the dust particles.

[0056] In this embodiment, the fixed insertion rail 11 is provided with an insertion groove 1101 for the insertion strip 13 to slide laterally, and the inner wall of the front side of the insertion groove 1101 is provided with a snap-fit ​​groove 1102 that cooperates with the snap-fit ​​spring piece 14.

[0057] Specifically, the dust removal mechanism is designed for easy and quick sliding installation, and the snap-fit ​​spring 14 is positioned and limited by the snap-fit ​​groove 1102, facilitating quick installation and fixation.

[0058] Please see Figure 8 In another embodiment of the present invention, the dust removal mechanism further includes a lifting adjustment assembly installed between the quick-release assembly and the mounting box 3. The lifting adjustment assembly includes a set of connecting rods 17 hinged to the top plate of the mounting box 3. A set of symmetrically arranged moving blocks 16 are hinged to the upper end of the connecting rods 17. The moving blocks 16 are slidably connected to a sliding rail 15 fixedly connected to the plug-in strip 13. A bidirectional lead screw 18 is nested inside the sliding rail 15 and threadedly connected to the moving blocks 16. The bidirectional lead screw 18 extends to the front side of the sliding rail 15 and is fixedly connected to a knob 19.

[0059] Specifically, by turning the knob 19, the bidirectional lead screw 18 drives the moving block 16 to move in opposite directions or in the sliding rail 15. The moving block 16 drives the mounting box 3 to move up and down through the connecting rod 17, thereby ensuring that the contact position between the traveling wheel 9 and the ground rail 2 maintains sufficient downward pressure and ensures that there is sufficient friction between the contact surface of the traveling wheel 9 and the ground rail 2. This allows the traveling wheel 9 to roll on the ground rail 2 when the elevator door 1 is closing. In addition, the height of the bucket block 4 can be adjusted so that the bucket block 4 contacts the bottom plate of the ground rail groove 201, ensuring the dust particle lifting and collection effect.

[0060] In this embodiment, the walking wheel 9 is a rubber wheel with equidistant anti-slip patterns on its circumference.

[0061] Specifically, improve the rolling stability of the walking wheel 9.

[0062] In this embodiment, the fixed insertion rail 11 is fixedly connected to the inner wall of the elevator door 1 by the fixing bolt 12; the top plate end of the fixed insertion rail 11 is hinged with a decorative panel 20 whose end face is flush with the front face of the mounting box 3, the front face of the mounting box 3 is flush with the front face of the elevator door 1, and a magnetic strip 21 that cooperates with the decorative panel 20 is fixedly connected to the upper end face of the mounting box 3.

[0063] Specifically, this ensures that the front surface of elevator door 1 remains flat and aesthetically pleasing, facilitates complete contact between the elevator door 1 and the contact surface when the door is closed, and also makes it convenient to maintain the dust removal mechanism.

[0064] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
