Description

Technical Field

[0001] The utility model relates to the technical field of elevator car equipment, in particular to an elevator car with an automatic guide rail cleaning function. Background Art

[0002] An elevator is a type of transportation equipment that transports pedestrians or goods vertically. Elevators serve buildings with specified floors. Vertical lift elevators have a car that runs between guide rails to facilitate passengers to enter and exit or load and unload goods. Elevators refer to electromechanical equipment that is powered by a box that runs on rigid guide rails or steps that run along fixed lines to lift or transport people or goods in parallel. Nowadays, there is a need for lubricating oil between the guide shoes and the guide rails of elevator cars, but the lubricating oil is applied to the outside of the guide rails, which can easily cause the lubricating oil to deteriorate in the friction between the guide shoes and the guide rails and cannot achieve the lubrication effect. The lubricating oil is also easily affected by external dust, causing the lubricating oil itself to be contaminated and deteriorated. The deteriorated lubricating oil has a high viscosity and is difficult to clean. Generally, the elevator needs to be stopped and cleaned slowly by humans. At the same time, the guide rails need to be smeared with kerosene after cleaning the lubricating oil to prevent sludge residue from causing poor elevator operation. Therefore, there is an urgent need for an elevator car with an automatic guide rail cleaning function.

[0003] According to an elevator car with an automatic guide rail cleaning function provided by patent application number CN202211400004.X, the automatic cleaning mechanism is moved to the outside of the elevator guide rail by pulling the elevator fixed frame and the elevator car through the elevator cable, and the rebound displacement column and the pressurizing platform are moved downward by squeezing the rebound plate through the fourth spring rebound to pull the rotating column to make the sludge scraper fit the outside of the elevator guide rail, thereby preventing the sludge scraper from being unable to fit the outside of the elevator guide rail due to wear and affecting the cleaning effect.

[0004] The disadvantages of the above device are that: during the use of the device, the sludge scraper of the entire device is always in close contact with the elevator guide rail, so it will continue to make noise during the operation of the elevator, and the lubricating oil applied on the elevator guide rail by the elevator rotating column will also be scraped off, and the elevator guide rail will be seriously worn after long-term use, resulting in a reduction in the service life of the equipment. During the use of the device, the lubricating oil scraped off will be wasted and cannot be recycled, so workers need to add lubricating oil frequently, which increases the labor intensity of workers and increases the cost of use, and thus the practicability is not high. Utility Model Content

[0005] The utility model aims to provide an elevator car with an automatic guide rail cleaning function to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an elevator car with an automatic guide rail cleaning function, comprising an elevator shaft, T-shaped guide rails are fixedly installed on the opposite side walls of the elevator shaft, a cleaning mechanism is slidably connected to the T-shaped guide rails, the cleaning mechanism is installed at the top end of a fixed frame, a car body is fixedly installed inside the fixed frame, a traction cable is installed in the middle of the top of the fixed frame, the cleaning mechanism comprises an oil sludge collection box, the oil sludge collection box is fixedly installed at the top end of the fixed frame, the oil sludge collection box is U-shaped and wraps the T-shaped guide rail, brackets are fixedly installed on both sides of the oil sludge collection box, and a mounting plate is fixedly installed on the top of the bracket.

[0007] As an optimal technical solution of the utility model, three groups of U-shaped mounting holes are provided on the mounting plate, a pair of connecting rods are installed on the side walls of the mounting holes through a rotating member, rollers are rotatably connected between the upper ends of the connecting rods, a scraper is installed at the end of the connecting rod through a rotating member, and the bottom of the scraper is close to the side wall of the sludge collection box.

[0008] As a preferred technical solution of the utility model, a filter hole is provided at the bottom of the sludge collection box, the filter hole is connected to the oil storage cavity provided at the bottom of the sludge collection box, and a filter net is fixedly installed at the filter hole.

[0009] As a preferred technical solution of the utility model, a groove is provided in the oil storage cavity near the T-shaped guide rail, an oil delivery cotton strip is installed between the groove and the oil storage cavity, and the oil delivery cotton strip is located in the groove and rollingly connected to a brush roller.

[0010] As the preferred technical solution of the utility model, a rotating shaft is fixedly installed on the axis of both sides of the brush roller, the rotating shaft is connected to a slider through a rotating member, the slider is slidably connected to a slide groove opened on the side wall of the groove, and a spring is fixedly connected between the slider and the side wall of the slide groove.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The scraper arranged in the cleaning mechanism of the device is not close to the T-shaped guide rail, so the surface of the T-shaped guide rail is always coated with lubricating oil. When the thickness of the sludge on the surface of the lubricating oil increases, the roller will drive the connecting rod to swing, thereby driving the front end of the scraper to approach the T-shaped guide rail to scrape off the sludge to a certain thickness, thereby ensuring the lubrication effect and improving the service life of the device. A filter screen is arranged between the sludge collection box and the oil storage chamber of the device, so the lubricating oil in the sludge will seep into the oil storage chamber again, so that the lubricating oil can be reused, avoiding workers from frequently adding lubricating oil, while reducing the cost of use, ensuring its good practicality.

[0020] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0021] See also Figure 1-4 According to an embodiment of the utility model, an elevator car with an automatic guide rail cleaning function includes an elevator shaft 1, T-shaped guide rails 2 are fixedly installed on the opposite side walls of the elevator shaft 1, and a cleaning mechanism 3 is slidably connected to the T-shaped guide rails 2. The cleaning mechanism 3 is installed at the top end of a fixed frame 4, and a car body 5 is fixedly installed inside the fixed frame 4. A traction cable 6 is installed in the middle of the top of the fixed frame 4. The cleaning mechanism 3 includes an oil sludge collecting box 7, which is fixedly installed at the top end of the fixed frame 4. The oil sludge collecting box 7 is U-shaped and wraps the T-shaped guide rail 2. Brackets 8 are fixedly installed on both sides of the oil sludge collecting box 7, and a mounting plate 9 is fixedly installed on the top of the bracket 8.

[0022] The traction cable 6 pulls the fixed frame 4 to move, thereby driving the car body 5 to move, and the sludge collecting box 7 collects the sludge scraped off from the scraper 13 .

[0023] In this embodiment, three groups of U-shaped mounting holes 10 are provided on the mounting plate 9, a pair of connecting rods 11 are installed on the side walls of the mounting holes 10 through a rotating member, rollers 12 are rotatably connected between the upper ends of the connecting rods 11, and a scraper 13 is installed at the end of the connecting rod 11 through a rotating member, and the bottom of the scraper 13 is closely attached to the side wall of the sludge collection box 7.

[0024] When the thickness of the sludge on the T-shaped guide rail 2 increases, the roller 12 will move outward, so the roller 12 drives the connecting rod 11 to swing, and the connecting rod 11 drives the front end of the scraper 13 to approach the T-shaped track 2 to scrape off the sludge on its surface.

[0025] In this embodiment, a filter hole 14 is provided at the bottom of the oil sludge collecting box 7 , the filter hole 14 is connected to an oil storage cavity 15 provided at the bottom of the oil sludge collecting box 7 , and a filter net 16 is fixedly installed at the filter hole 14 .

[0026] The lubricating oil in the sludge is filtered by the filter screen 16 and flows into the oil storage chamber 15 again, so that it can be recycled.

[0027] In this embodiment, a groove 17 is formed in the oil storage chamber 15 near the T-shaped guide rail 2 , and an oil transfer cotton strip 18 is installed between the groove 17 and the oil storage chamber 15 . The oil transfer cotton strip 18 is located in the groove 17 and is rollingly connected to a brush roller 19 .

[0028] The lubricating oil in the oil storage chamber 15 is attached to the brush roller 19 through the oil transfer cotton strip 18 , and then smeared on the T-shaped guide rail 2 through the brush roller 19 .

[0031] In specific application, first add the lubricating oil into the sludge collecting box 7, and then the lubricating oil will flow into the oil storage chamber 15 along the filter screen 16. After starting the elevator, the traction cable 6 pulls the car body 5 up and down through the fixed frame 4. At this time, the brush roller 19 rolls on the side wall of the T-shaped guide rail 2, and the lubricating oil in the oil storage chamber 15 adheres to the brush roller 19 along the oil transfer cotton strip 18, so as to be smeared on the T-shaped guide rail 2. When the sludge thickness on the T-shaped guide rail 2 increases to a certain value, it will drive the roller 12 to move outward, so the roller 12 drives the connecting rod 11 to swing, and the connecting rod 11 drives the front end of the scraper 13 to approach the T-shaped guide rail 2 to scrape the sludge on its surface to a certain thickness, thereby ensuring the stability of the car operation.
