Description

Technical Field

[0001] This utility model relates to the field of elevator guide rail rust removal technology, and in particular to an elevator guide rail rust removal device. Background Technology

[0002] Elevator guide rails are elevator components made of steel rails and connecting plates. They are divided into car guide rails and counterweight guide rails. While playing a guiding role, the guide rails also bear the impact force during car and elevator braking, as well as the impact force during emergency braking of the safety brake. The magnitude of these forces is related to the elevator's load capacity and speed. Therefore, the guide rails should be selected according to the elevator's speed and load capacity. The car guide rails are usually called the main rails, and the counterweight guide rails are called the auxiliary rails. After the elevator guide rails are manufactured, the outer surface of the elevator guide rails needs to be ground and rust-removed.

[0003] In existing technologies, the rust removal effect of elevator guide rail rust removal devices is limited by their adjustment parameters, making it difficult to achieve optimal adaptability in different usage scenarios and environments. Traditional devices usually adopt a fixed mode or a single adjustment method, which cannot be precisely adjusted according to the surface condition of the guide rail, resulting in uneven rust removal, low efficiency, or excessive rust removal that pollutes the surrounding environment. In addition, the lack of intelligent control functions requires operators to frequently adjust parameters to achieve the desired effect, increasing maintenance costs and reducing equipment safety.

[0004] In response to this technical problem, this application proposes an elevator guide rail rust removal device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an elevator guide rail rust removal device. The device uses a transmission rod to drive a worm gear and worm wheel, causing the cleaning wheel to rotate and clean the guide rail surface, removing residual rust. After the dust extraction fan is activated, the rust particles are sucked in and collected with the help of the interception net and the dust extraction port, and finally removed from the discharge port, thus completing the guide rail rust removal process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A rust removal device for elevator guide rails includes a loading shell. Support columns are fixedly connected to the four corners of the top of the loading shell. An electric hydraulic cylinder is fixedly connected to the front side of the top of the loading shell. The drive end of the electric hydraulic cylinder is connected to a rust-scraping blade via a rust-scraping assembly. A fixing shell is fixedly connected to the top of the support columns on the left and right rear sides. A motor is fixedly connected to the inner wall of the left end of the fixing shell. An electric hydraulic cylinder is fixedly connected to the left side of the top of the fixing shell. The drive end of the motor is connected to a cleaning wheel via a cleaning assembly.

[0007] Furthermore, the rust-scraping assembly includes a connecting frame fixedly connected to the second drive end of the electric hydraulic cylinder. Both ends of the connecting frame are rotatably connected to traction plates. The left and right ends of the traction plates are respectively rotatably connected to the top side of the opposite end of the rust-scraping blade. The inner wall of the rust-scraping blade is rotatably connected to the opposite end of the left and right support columns.

[0008] Furthermore, the cleaning component includes a transmission rod fixedly connected to a drive end of the motor, and the right end of the transmission rod is rotatably connected to the inner wall of the right end of the fixed housing.

[0009] Furthermore, a worm gear is slidably connected to the outer wall of the transmission rod, and adapter frames are slidably connected to the inner walls of the left and right sides of the top of the fixed shell. The outer wall of the worm gear is rotatably connected to the inner wall of the bottom end of the adapter frame.

[0010] Furthermore, racks are fixedly connected to opposite ends of the adapter frame, and a transmission gear is rotatably connected to the left end of the top of the fixed shell. The outer wall of the rack meshes with the outer wall of the transmission gear, and one drive end of the electric hydraulic cylinder is fixedly connected to the outer wall of the left adapter frame.

[0011] Furthermore, the rear end of the cleaning wheel penetrates through the outer wall of the adapter frame and is fixedly connected to a worm gear, which meshes with the outer wall of the worm.

[0012] Furthermore, a vacuum fan is fixedly connected to and passes through both the front and rear sides of the loading shell, and an intercepting net is installed at one end of the vacuum fan. A discharge port is provided on both the front and rear sides of the left end of the loading shell, and a vacuum port is fixedly connected to and passes through both the left and right sides of the inner wall of the loading shell.

[0013] This utility model has the following beneficial effects: In this invention, after the loading shell is fitted onto the outside of the guide rail, the electric hydraulic cylinder is activated by the external control device, which drives the connecting frame to move. This causes the traction plate to drive the rust scraper to deflect at the support column, pressing it against the guide rail surface and scraping away the rust. At the same time, another electric hydraulic cylinder is activated to move the adapter frame. The adapter frame, in conjunction with the rack and pinion and the transmission gear, drives the cleaning wheel to press against the outside of the guide rail. After the motor is started, the transmission rod drives the worm and worm wheel to rotate the cleaning wheel, cleaning the guide rail surface and removing residual rust. After the dust extraction fan is started, the rust particles are sucked in and collected by the interception net and the dust extraction port, and finally removed from the discharge port, completing the rust removal treatment of the guide rail.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figure 1 and Figure 2 An embodiment of this utility model provides an elevator guide rail rust removal device, including a loading shell 1. Support columns 2 are fixedly connected to the four corners of the top of the loading shell 1. An electric hydraulic cylinder 7 is fixedly connected to the front side of the top of the loading shell 1. The driving end of the electric hydraulic cylinder 7 is connected to a rust scraping blade 10 through a rust scraping assembly. The rust scraping assembly includes a connecting frame 8 fixedly connected to the driving end of the electric hydraulic cylinder 7. Traction plates 9 are rotatably connected to both ends of the connecting frame 8. The left and right ends of the traction plates 9 are rotatably connected to the top side of the opposite end of the rust scraping blade 10. The inner wall of the rust scraping blade 10 is rotatably connected to the opposite end of the support columns 2 at both ends.

[0018] Specifically, in the automatic rust removal operation of elevator guide rails, the operator first places and fixes the loading shell 1, which serves as the main support frame, on the outside of the elevator guide rail to be cleaned. Then, by issuing a command through an externally installed control device, the core power unit of the rust removal device, the electric hydraulic cylinder 7, is activated. Under the action of the drive signal, the hydraulic cylinder begins to work precisely, its piston rod producing linear motion, which in turn drives the connecting frame 8, rigidly connected to its output end, to produce horizontal or directional displacement. The displacement of the connecting frame 8 is transmitted to the traction mechanism in front of it—the traction plate 9—forcing it to deflect at a specific angle around the support column 2, which serves as a fixed fulcrum and guide reference. It is through the lever-like deflection of the traction plate 9 around the support column 2 that the rust removal tool—the rust scraper 10—fixed at its end, is ultimately driven to produce corresponding displacement and angle adjustment. The result of this series of precisely coordinated mechanisms is that the sharp edge of the rust scraper 10 can actively, stably, and tightly adhere to the side surface of the elevator guide rail. Finally, as the entire rust removal device moves along the guide rail or the rust scraper moves itself, under controllable pressure, the rust scraper 10 effectively scrapes, peels off and removes the stubborn rust layer attached to the guide rail surface, completing the core step of the rust removal task.

[0019] Reference Figure 3 and Figure 4 A fixed housing 4 is fixedly connected to the top of the left and right support columns 2 at the rear end. A motor 5 is fixedly connected to the inner wall of the left end of the fixed housing 4. An electric hydraulic cylinder 6 is fixedly connected to the left side of the top of the fixed housing 4. The drive end of the motor 5 is connected to a cleaning wheel 15 through a cleaning assembly. The cleaning assembly includes a transmission rod 14 fixedly connected to the drive end of the motor 5. The right end of the transmission rod 14 is rotatably connected to the inner wall of the right end of the fixed housing 4. A worm gear 16 is slidably connected to the outer wall of the transmission rod 14. Adapter frames 11 are slidably connected to the inner walls of the left and right sides of the top of the fixed housing 4. The outer wall of the worm gear 16 is rotatably connected to the inner wall of the bottom end of the adapter frame 11. The opposite ends of the adapter frame 11 are connected to each other. All are fixedly connected to racks 12. A transmission gear 13 is rotatably connected to the top left end of the fixed shell 4. The outer walls of racks 12 and transmission gear 13 mesh with each other. The drive end of electric hydraulic cylinder 6 is fixedly connected to the outer wall of the left end adapter 11. The rear end of cleaning wheel 15 passes through the outer wall of adapter 11 and is fixedly connected to worm gear 18. Worm gear 18 and worm 16 mesh with each other. Dust suction fans 3 are fixedly connected to and pass through the front and rear sides of loading shell 1. An interception net 20 is installed on one end of the dust suction fan 3. Discharge ports 17 are provided on the front and rear sides of the left end of loading shell 1. Dust suction ports 19 are fixedly connected to and pass through the left and right sides of the inner wall of loading shell 1.

[0020] Specifically: After scraping the rust off the elevator guide rail surface, the device enters the cleaning and rust collection stage. The operator first activates the electric hydraulic cylinder 6 via an external control device. Its piston rod drives the adapter 11 to produce a directional displacement. During this movement, the transmission gear 13, fixedly installed on the lower side or a specific part of the adapter 11, meshes with the rack 12 fixedly installed on the device body. This precise engagement of the gear and rack mechanism forces the adapter 11 to produce a more accurate and controllable linear relative movement based on the power provided by the electric hydraulic cylinder 6. This movement is directly transmitted to the cleaning wheel 15 installed on the adapter 11, causing it to approach the outer side of the elevator guide rail. By continuously controlling the stroke of the electric hydraulic cylinder 6, the cleaning wheel 15 is finally made to stably adhere to the outer surface of the elevator guide rail with appropriate pressure. Next, the operator activates the motor 5. The rotational power of the motor's output shaft is effectively transmitted to the input end of the worm gear 16 via the transmission rod 14. The worm gear 16 then meshes with the worm wheel 18. The worm gear reducer transmission mechanism not only reduces the output speed and increases the torque, but also changes the direction of power transmission. Under this transmission, the worm gear 18 drives the cleaning wheel 15, which is fixed coaxially with it, to rotate at high speed. The rotating cleaning wheel 15, which is attached to the surface of the guide rail, can be made of wire brush, nylon brush, or a combination of cleaning cloth, etc., and effectively cleans the surface of the guide rail by friction. It is especially effective in deeply cleaning the fine rust residue and dust left after the previous rust scraper 10, ensuring that the surface of the guide rail is clean. At the same time, in order to maintain a clean working environment and collect the generated rust dust, the device simultaneously starts the vacuum fan 3. The operation of this fan generates a strong negative pressure airflow, which is drawn through the suction ports 19 distributed near the cleaning wheel 15. The device efficiently sucks in rust, dust, and debris that fall off during the operation. As the dust-laden airflow flows through the internal filtration channel, it is critically intercepted and filtered by the interceptor net 20. This allows air to pass through while trapping and collecting solid rust particles in the device's pre-set dust collection chamber. Finally, after the cleaning work is completed, the operator can easily remove the collected rust waste by opening the discharge port 17. This achieves the harmless treatment and collection of rust debris. The coordinated operation of the rust scraping, cleaning, and collection functions greatly facilitates the entire device to achieve an efficient, thorough, and environmentally friendly rust removal process for elevator guide rails.

[0021] Working principle: After the loading shell 1 is fitted onto the outside of the guide rail, the external control device activates the electric hydraulic cylinder 7 to move the connecting frame 8, thereby causing the traction plate 9 to deflect the rust scraper 10 at the support column 2. This allows the rust scraper 10 to adhere to the guide rail surface and scrape away the rust. Simultaneously, when the electric hydraulic cylinder 6 is activated to move the adapter frame 11, the adapter frame 11 can move relative to the guide rail under the cooperation of the rack 12 and the transmission gear 13. This causes the adapter frame 11 to move relative to the cleaning wheel 15, thereby... When the cleaning wheel 15 is pressed against the outside of the guide rail and the motor 5 is started, the motor 5 drives the transmission rod 14 to drive the worm gear 16, which in turn drives the worm wheel 18 to rotate the cleaning wheel 15. This allows the cleaning wheel 15 to clean the surface of the guide rail and remove any scraped rust residue. The vacuum fan 3 is then started and, with the help of the interception net 20, the rust particles are sucked in and collected through the suction port 19. The collected rust particles can then be removed from the discharge port 17, making it convenient for the device to remove rust from the guide rail.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
