Technical Field

[0001] This utility model relates to the field of overhead cranes, and in particular to an automatic lubrication device for the steel wire rope of the traveling drum of an aluminum electrolysis overhead crane. Background Technology

[0002] Lack of lubrication in the wire ropes of aluminum electrolysis overhead cranes accelerates wear and aging, causing damage to the wire rope drums and pulley systems, and even leading to wire breakage and strand breakage, posing significant safety hazards. Manual lubrication takes 0.5-1 hour per cycle, and the high temperature and harsh working environment above the aluminum electrolysis plant result in heavy workload and long working hours for maintenance personnel. Furthermore, the presence of alumina particles and dust in the plant air causes the wire rope lubricant to easily absorb dust and deteriorate, increasing the frequency of lubrication and further increasing the workload for maintenance personnel. Therefore, designing an automatic lubrication device for the wire ropes of aluminum electrolysis overhead crane drums that can provide real-time lubrication is particularly urgent.

[0027] 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.

[0028] The purpose of this invention is to provide an automatic lubrication device for the steel wire rope of the overhead crane drum in aluminum electrolysis, so as to solve the problems existing in the prior art and to lubricate the steel wire rope of the crane in real time.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1-2 As shown, this utility model provides an automatic lubrication device for the wire rope of the overhead crane drum in aluminum electrolysis, including a roller brush 1 and an oil supply device; wherein the roller brush 1 is disposed on the first support structure and keeps in contact with the wire rope wound on the wire rope drum 3. When the wire rope rotates, it rotates under the drive of the friction between the roller brush 1 and the wire rope; the oil outlet 2 of the oil supply device is disposed above the roller brush 1 for replenishing the roller brush 1 with lubricant.

[0031] When the wire rope drum 3 rotates, the roller brush 1 rotates under the friction of the wire rope. Lubricant is added to the roller brush 1 through the oil outlet 2 on the oil supply device, so that the roller brush 1 can evenly apply the lubricant to the wire rope while rotating, realizing real-time automatic lubrication of the overhead crane wire rope, which also effectively reduces labor costs.

[0032] As an example of an implementable approach, such as Figures 1-2As shown, the first support structure includes a roller brush bracket 11 and a support frame 4. The roller brush 1 is rotatably mounted on the roller brush bracket 11, while the support frame 4 is fixedly connected to the overhead crane steel structure and hinged to the roller brush bracket 11. This allows the roller brush 1 to hang naturally under its own weight and maintain contact with the wire rope. The roller brush 1 can rotate on its own driven by the wire rope without additional force, making the structure very simple. Alternatively, tension springs can be installed and connected to both the roller brush bracket 11 and the support frame 4. Under the action of the tension springs, the pressure of the roller brush 1 on the wire rope is increased, thereby increasing the friction between the roller brush 1 and the wire rope, preventing the roller brush 1 from slipping, and improving the uniformity of lubricant application. The overhead crane steel structure mentioned here refers to the overhead crane steel structure that fixes the wire rope roller 3.

[0033] As an example of an implementable approach, such as Figures 1-2 As shown, a brush 5 can also be provided, which is placed on the second support structure and located below the center line of the wire rope drum 3, and in contact with the wire rope to be wound onto the wire rope drum 3; wherein the projection of the brush 5 on the axial direction of the wire rope drum 3 covers the winding area of ​​the wire rope on the wire rope drum 3, so as to ensure that the brush 5 is in continuous contact with the wire rope; during the up-down and left-right movement of the wire rope to be wound, it rubs against the brush 5, so that the brush 5 cleans the dust such as alumina powder adhering to the wire rope to be wound, such as preventing the lubricant on the wire rope from absorbing dust and deteriorating, thereby saving the amount of lubricant used and reducing lubrication costs.

[0034] As an example of an implementable approach, such as Figures 1-2 As shown, the second support structure is provided with a brush bracket 51; the brush 5 is connected to the brush bracket 51; the brush bracket 51 is hinged to the support frame 4, and the hinge point is lower than the installation height of the brush 5, so that the brush 5 can hang down naturally by its own weight without external force and abut against the wire rope. The overall structure is simple and the manufacturing cost is low.

[0035] Of course, the brush bracket 51 can also be directly fixed on the overhead crane steel structure, where the overhead crane steel structure refers to the overhead crane steel structure that fixes the wire rope drum 3.

[0036] As an example of an implementable approach, such as Figures 1-2 As shown, multiple oil outlets 2 are evenly distributed along the axial direction of the roller brush 1 and connected to an oil pump 7 via an oil pipe 6. The oil pump 7 is connected to an oil storage tank 8. The oil pump 7 delivers the lubricant from the oil storage tank 8 to the oil outlets 2, which then drips onto the roller brush 1. The even distribution of the oil outlets 2 makes the lubricant distribution on the roller brush 1 more uniform, thereby making the lubrication of the wire rope more uniform and sufficient. Of course, the oil supply device can also adopt a gravity-feed method, which eliminates the need for the oil pump 7. For example, the oil storage tank 8 can be positioned higher than the oil outlets 2, and the orifice of the oil outlets 2 can be designed to ensure the rate of lubricant delivery.

[0037] Of course, considering the need to simplify the equipment, only one oil outlet 2 can be set. The lubricant dripped onto the roller brush 1 gradually wets the entire bristles of the roller brush 1, and then the bristles lubricate the steel wire rope in contact with the roller brush 1.

[0038] As an example of an implementable approach, such as Figures 1-2 As shown, both the roller brush 1 and the brush 5 are parallel to the axis of the wire rope drum 3, and at least two roller brushes 1 are arranged along the axial direction of the wire rope drum 3 to reduce the rotational resistance of the wire rope drum 3 and improve the rotational smoothness of the brush 5.

[0039] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
