Description

Technical Field

[0001] The utility model relates to the technical field of elevator guide rails, in particular to an elevator guide rail cleaning device. Background Art

[0002] Elevator guide rails are elevator components composed of steel rails and connecting plates, and are divided into car guide rails and counterweight guide rails. They are divided into three types according to the cross-sectional shape: T-shaped, L-shaped and hollow. While playing a guiding role, the guide rails also bear the impact force of the car and elevator during braking, the impact force of the safety clamp during emergency braking, etc.

[0003] The Chinese utility model patent with the authorization announcement number "CN212127211U" is specifically "an elevator guide rail cleaning device". The specific implementation method of its specification records that "the length direction of the vertical arm of the sticky plate in this embodiment is consistent with the width direction of the guide rail, and the length of the vertical arm is greater than the width of the guide rail, so that it can span above the guide rail. When installing, the magnet is slid up and down on the end of the hanging plate as needed, so that the sticky plate is at different heights. After installation, the bottom of the cleaning sheet (the inner side wall of the groove) contacts the surface of the guide rail. When the hanging plate is moving, the cleaning sheet scrapes off dust and other debris adhering to the surface of the guide rail to keep the surface of the guide rail clean. The structure after adopting this embodiment is reasonable, and the existing guide rail can be directly improved and installed. It is easy to install and has a good cleaning effect."

[0004] The above device uses a cleaning sheet to scrape off debris on the surface of the guide rail, but as the working time of the cleaning sheet increases, more dust is scraped off, resulting in insufficient contact between the cleaning sheet and the surface of the guide rail, reducing the cleaning effect of the cleaning sheet. At the same time, the debris scraped off by the cleaning sheet is easily attached to the guide rail for a second time, further reducing the cleaning effect of the cleaning sheet. In addition, the cleaning sheet is in contact with the guide rail for a long time to scrape off debris, which causes great wear and tear and requires frequent replacement. The cleaning sheet is installed in a relatively small space such as an elevator, and each replacement is difficult to disassemble and assemble, which is inconvenient to use. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the utility model provides an elevator guide rail cleaning device, which can effectively solve the problems of poor cleaning effect and the need for frequent and inconvenient replacement in the prior art.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The utility model provides an elevator guide rail cleaning device, comprising a mounting plate and two fixed plates mounted on one side of the mounting plate, a fan mounted on the side of the mounting plate away from the two fixed plates, a cleaning component comprising a rotating cylinder rotatably mounted between the two fixed plates and connected to an input end of the fan, a sponge sleeve being sleeved on the surface of the rotating cylinder, the rotating cylinder and the sponge sleeve being connected to each other, a collecting component comprising a filter screen box mounted on the side of the mounting plate away from the fan and opposite to the fan, a paddle being fixedly mounted in the filter screen box and in rolling contact with the sponge sleeve.

[0008] Furthermore, air outlets are provided through both sides of the mounting plate, and the input end of the fan and the filter box are respectively arranged on both sides of the air outlet.

[0009] Furthermore, large screws are threadedly installed at the four corners of the mounting plate, and inner lining plates fixedly installed on the mounting plate are provided on both sides of the fan.

[0010] Furthermore, two L-shaped mounting seats are installed on the side of the mounting plate away from the fan and are respectively located on both sides of the exhaust port, and small screws are installed on the L-shaped mounting seats.

[0011] Furthermore, docking rings are installed at both ends of the rotating cylinder, and an air inlet pipe penetrating the fixing plate and the mounting plate and communicating with the input end of the fan is rotatably installed at one end of the docking ring away from the rotating cylinder.

[0012] Furthermore, the outer cylinder wall of the rotating cylinder penetrates through the inner cylinder cavity and is provided with a plurality of evenly distributed air inlet holes.

[0013] Furthermore, both ends of the filter box are equipped with slide bars which are slidably inserted into the corresponding L-shaped mounting seats, and the slide bars are penetrated by threaded holes which are compatible with small screws.

[0014] Compared with the known prior art, the technical solution provided by the utility model has the following beneficial effects:

[0015] 1. The rotating sponge sleeve is set to roll in contact with the guide rail, replacing the sliding contact between the cleaning sheet and the guide rail in the reference document. This can reduce wear without reducing the cleaning effect, thereby reducing the replacement frequency, and is easy to use;

[0016] 2. When the sponge cover rolls with the guide rail to scrape off the debris on the guide rail, the scraper will promptly scrape off the debris on the sponge cover, so that the sponge cover is always in full contact with the guide rail, and the scraped debris will be collected in the filter box located at the exhaust port through the negative pressure suction of the fan, so as to avoid the debris from scattering and attaching to the guide rail for the second time, which has the characteristics of good cleaning effect.

[0024] The utility model is further described below in conjunction with embodiments.

[0025] Example 1

[0026] Reference Figure 1-4, which is the first embodiment of the utility model, discloses an elevator guide rail cleaning device, including a mounting plate 1 and two fixed plates 2 mounted on one side of the mounting plate 1, a fan 12 mounted on the side of the mounting plate 1 away from the two fixed plates 2, a cleaning component including a rotating cylinder 21 rotatably mounted between the two fixed plates 2 and connected to the input end of the fan 12, a sponge cover 25 is sleeved on the surface of the rotating cylinder 21, the rotating cylinder 21 and the sponge cover 25 are connected to each other, a collecting component including a filter box 3 mounted on the side of the mounting plate 1 away from the fan 12 and opposite to the fan 12, a paddle 31 in rolling contact with the sponge cover 25 is fixedly mounted in the filter box 3, when the sponge cover 25 rotates, the paddle 31 is moved to scrape off the debris adsorbed on the surface, and the debris is collected in the filter box 3 by negative pressure suction.

[0027] Example 2

[0028] Reference Figure 1-4 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: exhaust ports 11 are provided on both sides of the mounting plate 1, and the input end of the fan 12 and the filter box 3 are respectively arranged on both sides of the exhaust port 11, so as to completely wrap the exhaust port 11 to prevent air from entering the exhaust port 11 without passing through the filter box 3, thereby causing blockage inside the fan 12. Large screws 13 are threadedly installed on the four corners of the mounting plate 1, and inner lining plates 14 fixedly installed on the mounting plate 1 are arranged on both sides of the fan 12, so that a gap can be reserved between the output end of the fan 12 and the elevator car to ensure smooth exhaust of the motor 12. Two L-shaped mounting seats 15 located on both sides of the exhaust port 11 are installed on the side of the mounting plate 1 away from the fan 12, and small screws 16 are installed on the L-shaped mounting seats 15. The rotating cylinder 21 Docking rings 22 are installed at both ends of the filter box 3. The docking ring 22 is rotatably installed at one end away from the rotating cylinder 21 with an air inlet pipe 23 that penetrates the fixed plate 2 and the mounting plate 1 and is connected to the input end of the fan 12. The outer cylinder wall of the rotating cylinder 21 penetrates the inner cylinder cavity and opens a number of evenly distributed air inlet holes 24. Air on the surface of the sponge cover 25 is extracted through the air inlet holes 24, so that when the surface of the sponge cover 25 is scraped off, the debris can be adsorbed and fixed on the surface of the sponge cover 25 to avoid scattering and polluting the elevator room. Both ends of the filter box 3 are equipped with sliding bars 32 that are slidably inserted into the corresponding L-shaped mounting seats 15. The sliding bars 32 are penetrated with threaded holes 33 that are compatible with the small screws 16. The length of the sliding bar 32 is less than the length of the L-shaped mounting seat 15 and can be stuck in the L-shaped mounting seat 15. The small screws 16 can realize the limited fixation of the sliding bar 32.

[0029] The remaining structures are the same as those of Example 1.

[0030] The workflow of this utility model is as follows:

[0031] First, the slide bars 32 on both sides of the filter box 3 are respectively inserted into the corresponding L-shaped mounting seats 15, and the small screws 16 are passed through the corresponding threaded holes 33 and threadedly mounted on the mounting plate 1, so that the filter box 3 and the paddle 31 are firmly installed, and then the mounting plate 1 is installed on the elevator car as a whole by the large screws 13, at this time, the sponge cover 25 is in rolling contact with the guide rail;

[0032] Secondly, when the elevator car moves up and down, the sponge cover 25 rolls with the guide rail to scrape off the debris on the guide rail, and scrapes off the debris on the sponge cover 25 by contacting with the paddle 31 in the filter box 3. At the same time, the fan 12 is started to extract air from the exhaust port 11, so that the debris scraped off the sponge cover 25 is sucked into the filter box 3 by negative pressure;

[0033] Finally, when the fan 12 is exhausting air, it will draw air from the inner cavity of the rotating cylinder 21 through the air inlet pipe 23, and draw air from the surface of the sponge cover 25 through a plurality of air inlet holes 24, so that when the sponge cover 25 scrapes off the debris on the guide rail, the debris can be adsorbed on the surface of the sponge cover 25, thereby preventing the debris from scattering and improving the cleaning effect.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
