Description

Technical Field

[0001] This utility model relates to the field of steel wire rope production technology, and in particular to a surface impurity cleaning device for elevator steel wire rope production. Background Technology

[0002] Elevator wire rope is a core load-bearing and transmission component in the elevator operating system. It is mainly used to connect the car and counterweight, bear the entire weight of the elevator during lifting and lowering, and transmit power. It is usually made of multiple high-strength steel wires twisted together. The outer layer is mostly a round strand structure, and the inner layer contains a fiber core or steel core to enhance flexibility and fatigue resistance. The surface is often galvanized or phosphated to improve rust prevention and wear resistance. Its performance is directly related to elevator safety and must meet requirements such as high strength, low elongation, and impact resistance. It needs to be inspected regularly for wear, broken wires, rust, etc. It is a key component to ensure the stable operation of the elevator.

[0003] A search revealed that the document with publication number "CN216863329U" mentions "a utility model that discloses an elevator wire rope maintenance device, including a maintenance applicator box. A mounting block is fixedly installed in the middle right side of the maintenance applicator box, and an oil groove is opened in the middle left side of the maintenance applicator box. A sealing mounting block is installed on the top of the oil groove through a disassembly and assembly mechanism. A wire rope body passes through the middle right side of the maintenance applicator box, and the outer wall of the left side of the wire rope body abuts against the outer wall of multiple sets of ball bearings. The ball bearings are equidistantly rolled and embedded in the inner wall of the maintenance applicator box." In use, this utility model can relatively conveniently and effectively fill the oil groove with lubricating oil. Simultaneously, under the action of the ball bearings, the wire rope body can be lubricated while in use, improving the working efficiency of the device during operation.

[0004] However, after elevator wire ropes are manufactured, their surfaces are prone to being covered with impurities such as metal shavings, oxide scale, and dust. At this time, it is necessary to clean the surface of the wire rope. However, existing cleaning equipment mostly uses simple scraping or wiping methods, which can only clean the top and bottom or left and right sides of the wire rope, making it difficult to achieve a comprehensive cleaning of the circumferential surface of the wire rope. In addition, during the grinding process, there are a lot of debris, which can easily cause environmental pollution if not properly collected. Furthermore, the vibration during the cleaning process can easily cause the wire rope to shake, thus increasing the difficulty of cleaning.

[0005] Therefore, we provide a surface impurity cleaning device for elevator wire rope production to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: A surface impurity cleaning device for elevator wire rope production includes a lower cleaning frame. An elevator wire rope impurity cleaning assembly is installed on the inner side of the lower cleaning frame. The elevator wire rope impurity cleaning assembly includes a lower reverse motor installed on the right side of the lower cleaning frame. A concave grinding disc is installed at the top inner side of the lower cleaning frame. Side grinding brushes are provided at both ends of the inner side of the concave grinding disc, and a lower grinding brush is provided in the middle of the inner side of the concave grinding disc. Connecting supports are installed on both the front and rear sides of the lower cleaning frame. A hydraulic lifting column is welded to the top of each connecting support. An upper cleaning frame is installed at the top of each hydraulic lifting column. An upper reverse motor is installed on the outer side of the upper cleaning frame, and an upper grinding brush is installed in the middle of the upper cleaning frame. An impurity collection assembly is provided on the front side of the connecting support. The impurity collection assembly includes a side slot located inside the connecting support. A side impurity collection chamber is connected to the inner groove of the side slot. A lower impurity collection chamber is provided on the lower side of the concave grinding disc.

[0007] As a further description of the above technical solution: The lower reverse motor is axially connected to the concave grinding disc. The lower reverse motor drives the concave grinding disc to rotate in the opposite direction, while the upper reverse motor rotates in the same direction as the lower reverse motor.

[0008] As a further description of the above technical solution: The side polishing brushes are symmetrically arranged on the left and right sides. The lower polishing brush is located in the middle of the side polishing brushes. The side polishing brushes and the lower polishing brushes form a U-shaped structure. The upper polishing brushes, the side polishing brushes, and the lower polishing brushes form a square-shaped structure.

[0009] As a further description of the above technical solution: The upper cleaning frame and the hydraulic lifting column are welded together, and the upper cleaning frame and the connecting support column form a lifting structure through the hydraulic lifting column.

[0010] As a further description of the above technical solution: The side impurity collection chamber is connected to the side slot by a slot.

[0012] As a further description of the above technical solution: A side frame is installed on the rear side of the lower cleaning frame. A driven rotating shaft is connected to the middle of the top of the side frame. A wire rope support concave plate is welded to the middle of the driven rotating shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes an elevator wire rope impurity cleaning component. When cleaning the elevator wire rope, the wire rope passes between the concave grinding disc and the upper grinding brush. The upper and lower reverse motors drive the concave grinding disc and the upper grinding brush to rotate synchronously in opposite directions, thereby grinding and cleaning the surface of the wire rope. The elevator wire rope passes between the side grinding brush and the lower grinding brush. The side grinding brush grinds the left and right sides, while the lower grinding brush grinds the lower side, and the upper grinding brush grinds the upper side, thus achieving all-round grinding and cleaning of the elevator wire rope. The brush grinding method can effectively remove impurities from the gaps in the wire rope without damaging the surface of the wire rope.

[0014] 2. This utility model utilizes an impurity collection component. When needed, the side and lower grinding brushes perform reverse grinding and cleaning of the wire rope. The side impurity collection chamber effectively collects impurities that fall off during the grinding process, facilitating subsequent cleaning. During grinding, a significant amount of impurities fall downwards, which the lower impurity collection chamber captures. The semi-circular structure on the side of the lower impurity collection chamber effectively captures splashed impurities, thereby reducing the spread of impurities. The wire rope support concave plate at the top of the side frame, supported by the driven rotating shaft, provides some support for the elevator wire rope, reducing its sway during grinding and thus improving grinding stability and precision.

[0017] 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.

[0018] Please see Figure 1-4 As shown, this utility model provides a technical solution: a surface impurity cleaning device for elevator wire rope production, including a lower cleaning frame 1, an elevator wire rope impurity cleaning component 2 installed on the inner side of the lower cleaning frame 1, the elevator wire rope impurity cleaning component 2 including a lower reverse motor 201 installed on the right side of the lower cleaning frame 1, a concave grinding disc 202 installed at the top inner side of the lower cleaning frame 1, side grinding brushes 203 provided at the left and right ends of the inner side of the concave grinding disc 202, a lower grinding brush 204 provided in the middle of the inner side of the concave grinding disc 202, and connecting supports installed on both the front and rear sides of the lower cleaning frame 1. The top of the column 205 and the connecting column 205 are both welded with hydraulic lifting columns 206. The top of the hydraulic lifting column 206 is equipped with an upper cleaning frame 207. An upper reverse motor 208 is installed on the outside of the upper cleaning frame 207. An upper grinding brush 209 is installed in the middle of the upper cleaning frame 207. An impurity collection component 3 is provided on the front side of the connecting column 205. The impurity collection component 3 includes a side slot 301 provided on the inside of the connecting column 205. A side impurity collection chamber 302 is connected to the inner slot of the side slot 301. A lower impurity collection chamber 303 is provided on the lower side of the concave grinding disc 202.

[0019] Furthermore, the lower reverse motor 201 and the concave grinding disc 202 are connected by a shaft. The lower reverse motor 201 drives the concave grinding disc 202 to rotate in the opposite direction. The upper reverse motor 208 rotates in the same direction as the lower reverse motor 201. When cleaning the elevator wire rope, the elevator wire rope passes between the concave grinding disc 202 and the upper grinding brush 209. The upper reverse motor 208 and the lower reverse motor 201 drive the concave grinding disc 202 and the upper grinding brush 209 to rotate synchronously in opposite directions, thereby grinding and cleaning the surface of the wire rope.

[0020] Furthermore, the side grinding brushes 203 are symmetrically arranged on the left and right sides, and the lower grinding brush 204 is located in the middle of the side grinding brushes 203. The side grinding brushes 203 and the lower grinding brush 204 form a U-shaped structure, and the upper grinding brush 209 forms a square structure with the side grinding brushes 203 and the lower grinding brush 204. When needed, the elevator wire rope passes between the side grinding brushes 203 and the lower grinding brush 204. The side grinding brushes 203 grind the left and right sides, while the lower grinding brush 204 grinds the lower side, and the upper grinding brush 209 grinds the upper side, thereby achieving all-round grinding and cleaning of the elevator wire rope. The brush grinding method can effectively clean the impurities in the gaps of the wire rope without damaging the surface of the wire rope.

[0021] Furthermore, the upper cleaning frame 207 and the hydraulic lifting column 206 are welded together. The upper cleaning frame 207 and the connecting support column 205 form a lifting structure through the hydraulic lifting column 206. When needed, the height of the upper cleaning frame 207 is adjusted according to the different diameters of the elevator wire rope so that the gap between the upper grinding brush 209 and the concave grinding disc 202 matches the diameter of the wire rope. This avoids incomplete grinding due to excessive gap or wear of the equipment due to insufficient gap, thereby improving cleaning efficiency and equipment service life.

[0022] Furthermore, the side impurity collection chamber 302 is connected to the side slot 301 by a slot. The side impurity collection chamber 302 is in the rotation direction of the upper reverse motor 208 and the lower reverse motor 201. The middle position of the side impurity collection chamber 302 is at the horizontal position of the lower reverse motor 201. When needed, since the side grinding brush 203 and the lower grinding brush 204 perform reverse grinding and cleaning on the wire rope, the side impurity collection chamber 302 can effectively collect the impurities that fall off during the grinding process, which is convenient for subsequent cleaning work.

[0023] Furthermore, the lower impurity collection chamber 303 is connected to the lower cleaning frame 1 by a slot. The lower impurity collection chamber 303 has a semi-arc structure. During the grinding process, a lot of impurities will fall downwards. At this time, the lower impurity collection chamber 303 can capture the impurities falling downwards. The semi-arc structure on the side of the lower impurity collection chamber 303 can effectively capture splashed impurities, thereby reducing the diffusion range of impurities.

[0024] Furthermore, a side frame 304 is installed on the rear side of the lower cleaning frame 1. A driven rotating shaft 305 is connected to the middle of the top of the side frame 304. A wire rope support concave plate 306 is welded to the middle of the driven rotating shaft 305. The height of the wire rope support concave plate 306 is at the same level as the middle height of the concave grinding disc 202. When needed, the wire rope support concave plate 306 at the top of the side frame 304 can provide a certain support for the elevator wire rope through the support of the driven rotating shaft 305, reducing the swaying amplitude of the wire rope during the grinding process, thereby improving the grinding stability and accuracy.

[0025] Working principle: When needed, the lower cleaning frame 1 is fixed to the desired position with bolts. Then, the elevator wire rope passes through the side grinding brush 203 and the lower grinding brush 204 inside the concave grinding disc 202. After passing through, the hydraulic lifting column 206 on the connecting support 205 drives the upper cleaning frame 207 downward until the upper grinding brush 209 is embedded in the groove formed by the side grinding brush 203 and the lower grinding brush 204. Once ready, the lower reverse motor 201 and the upper reverse motor 208 drive the concave grinding disc 202 and the upper grinding brush 204... 09. The wire rope is cleaned by reverse rotation. Impurities generated and projected in the direction of the projectile are captured by the side impurity collection chamber 302 in the side slot 301, while impurities that fall naturally are captured by the lower impurity collection chamber 303. During the grinding process, the cleaned wire rope is supported by the wire rope support concave plate 306 on the side frame 304 to reduce the swaying of the wire rope. The wire rope support concave plate 306 is driven to rotate by the driven rotating shaft 305. This completes the use process of a surface impurity cleaning device for elevator wire rope production.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
