Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a portable elevator guide rail cleaning device. Background Technique

[0002] An elevator refers to a permanent transportation device that serves several specific floors in a building, and its car runs on at least two rigid tracks perpendicular to the horizontal plane or with an inclination angle less than 15° to the plumb line. The main equipment for elevator operation includes guide rails, cars, traction machines, and steel cables. Among them, the guide rails play a certain guiding role. Since there will be some impurities and garbage on the guide rails after long-term use, it is necessary to clean the guide rails in time to ensure the normal operation of the car.

[0003] In the existing cleaning methods for guide rails, most of them are to stop the elevator car and then have workers enter the elevator shaft to perform manual or automatic cleaning on the guide rails. This cleaning method is not only inefficient, but also the workers need to be in the elevator shaft, which is relatively risky and inconvenient. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a portable elevator guide rail cleaning device, which can automatically clean the guide rails through the movement of the elevator car without workers entering the elevator shaft, so as to solve the problems raised in the above background technique.

[0017] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0018] All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any manner.

[0019] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically stated, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0020] As Figure 1 、 Figure 2 and Figure 3 shown, a portable elevator guide rail cleaning device of the present utility model includes an elevator car 1. A strip-shaped opening is provided on the top surface of the elevator car 1. Adjusting plates 2 are movably installed at both ends of the strip-shaped opening. Support rods 3 are installed on the outer side surfaces of the adjusting plates 2. The other ends of the support rods 3 are installed with U-shaped shells 4. Extended portions are formed by extending both sides of the U-shaped shell 4. Cleaning layers 6 are provided on the inner side surfaces of the extended portions and the U-shaped shell 4. A lifting plate 7 for driving the adjusting plate 2 to move upward and be fixed is installed in the strip-shaped opening.

[0021] In this embodiment, grooves are provided at both ends of the lifting plate 7, and magnets 8 are installed in the grooves. The adjusting plates 2 are all made of metal materials, and the magnets 8 are magnetically fixed to the adjusting plates 2.

[0022] In this embodiment, a lead screw hole is provided in the middle of the lifting plate 7. A lead screw 11 is threadedly connected in the lead screw hole. One end of the lead screw 11 extends into the interior of the elevator car 1 and is installed with a limit block 12. The other end of the lead screw 11 is installed with a motor 10 for driving the lead screw 11 to rotate. A fixing frame is installed between the motor 10 and the elevator car 1.

[0023] In this embodiment, partition plates 9 are installed on both sides of the strip-shaped opening. The distance between the partition plates 9 matches the widths of the adjusting plates 2 and the lifting plate 7. Shaft rods 14 are installed at opposite ends of the adjusting plates 2. Shaft holes are provided in the partition plates 9 and the strip-shaped opening corresponding to the shaft rods 14. Both ends of the shaft rods 14 are inserted into the shaft holes. Rubber rings are installed on the inner wall surfaces of the shaft holes. The inner circumferential surfaces of the rubber rings are in frictional contact with the outer wall surfaces of the shaft rods 14;

[0024] Among them, the friction with the shaft rod is increased through the rubber ring. When the adjusting plate rotates downward, the friction with the rubber ring can increase the damping effect to reduce the downward rotation speed of the adjusting plate and increase safety.

[0025] In this embodiment, a plurality of positioning plates 13 are installed on the inner top surface of the elevator car 1, and the positioning plates 13 are arranged on both sides of the strip-shaped opening.

[0026] In this embodiment, chamfers with an arc structure are provided at the opposite ends of the magnet 8 to increase the contact area with the magnet when the adjusting plate is tilted, avoiding breakage caused by the overly sharp corners of the magnet.

[0027] Among them, the cleaning layer can be made of microfiber cloth or a cleaning brush with hard or soft bristles to ensure the cleaning quality of the guide rail. The cleaning layer can be fixed to the U-shaped shell and the extension part through other adhesive materials such as double-sided tape. When the cleaning layer needs to be replaced, it can be directly torn off for replacement. Therefore, usually, only the cleaning layer needs to be carried, which increases convenience.

[0028] When cleaning is required, the motor is started. The start of the motor drives the lead screw, and the rotation of the lead screw drives the lifting plate, enabling the lifting plate to move upward along the partition. The movement of the lifting plate can push the adjusting plate upward, causing the adjusting plate to lift upward with the shaft rod as the center. The movement of the adjusting plate drives the support rod and the U-shaped shell until the U-shaped shell is sleeved outside the guide rail, and the cleaning layer contacts the outer side surface of the guide rail. Among them, the area of the cleaning layer is increased through the extension part, enabling the cleaning layer to contact both side plates of the guide rail, increasing the comprehensiveness of cleaning; when the elevator car is moving, the cleaning layer can scrape off dirt such as dust adhering to the surface of the guide rail to achieve the purpose of cleaning the guide rail.

[0029] Among them, when not in use, the motor is started in the reverse direction, thereby driving the lifting plate to descend until it enters between the positioning plates. The suction force of the magnet can synchronously pull the adjusting plate downward until the adjusting plate enters the strip-shaped opening. After the adjusting plate is horizontally arranged, the strip-shaped opening can be sealed by the adjusting plate and the lifting plate, and the adjusting plate can be adsorbed by the magnet to ensure stability.

[0030] Among them, when the cleaning layer needs to be replaced, the motor is started in the reverse direction continuously, causing the lifting plate to continue to move downward until the lifting plate disengages from between the positioning plates. At this time, the lifting plate can rotate along the thread of the lead screw. After the lifting plate is longitudinally arranged, the adjusting plate can rotate downward with the shaft rod as the center until it enters the elevator car, enabling the staff to replace the cleaning layer inside the elevator car, greatly increasing safety.

[0031] As described above, it is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be thought of without creative labor should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope defined by the claims.
