Abstract
Description
Technical Field
[0001] The utility model belongs to the field of slewing bearings and relates to lubrication technology, in particular to a slewing bearing lubrication system for cable processing. Background Art
[0002] Lubrication is essential for all mechanical equipment. As long as there are relatively moving surfaces, lubrication is required. Reasonable lubrication can effectively prevent and delay wear between equipment parts and increase the service life of the equipment. Lubrication is the top priority of equipment maintenance.
[0003] In the cable stranding process, a cable strander is needed to complete the task. As an important component of the cable strander, if the slewing bearing is not properly lubricated, problems such as jamming, vibration, and noise may occur, and in severe cases, engineering accidents may happen. Currently, most lubrication systems for slewing bearings are controlled by connecting a lubrication pump station to an external intelligent terminal and achieving lubrication of the slewing bearing through a distributor and branch oil pipes. However, this system still has certain defects. For example, during application, due to external factors such as aging or wear, the branch oil pipes may be damaged without being detected. Then, when the lubrication system operates, the lubricating grease will overflow from the damaged part, that is, the lubricating grease is not delivered to the designated lubrication point, resulting in problems such as jamming, vibration, and wear of the subsequent slewing bearing due to insufficient lubrication.
[0004] Therefore, a slewing bearing lubrication system for cable processing is needed to solve the above problems. Summary of the Utility Model
[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a slewing bearing lubrication system for cable processing, which can monitor whether the lubricating grease is output to the designated lubrication point when the lubrication system operates, thus ensuring the normal operation of the subsequent slewing bearing and preventing problems such as jamming, vibration, and wear of the slewing bearing due to poor lubrication effect caused by the lubricating grease not being output to the designated lubrication point. The utility model is provided with a plurality of oil outlets arranged around one end of the branch oil pipe connected to the slewing bearing and a negative feedback component including a fixed disc, a sliding column, and a pressure sensor. When the lubrication pump station outputs lubricating grease and the lubricating grease enters the designated lubrication point through the oil outlet, it will push the sliding column into contact with the pressure sensor. Therefore, during the process of adding lubricating grease once, it is possible to monitor whether there is a change in the reading of the pressure sensor to indicate whether the lubricating grease is discharged from the oil outlet, thereby realizing the function of monitoring whether the lubricating grease is discharged to the designated lubrication point and providing guarantee for the normal operation of the subsequent slewing bearing.
[0006] To achieve the above object, a first aspect of the present utility model provides a slewing bearing lubrication system for cable processing, which includes a lubrication pump station, a main oil pipe, a distributor, branch oil pipes, and a negative feedback component;
[0007] The output end of the lubrication pump station is connected to one end of the main oil pipe, and the other end of the main oil pipe is connected to the distributor;
[0008] A plurality of branch oil pipes are provided, one end of which is connected to the outer ring of the slewing bearing, and the other end is connected to the distributor. When the lubrication pump station operates, lubricating grease is output into the distributor and output to multiple lubrication points of the slewing bearing through the plurality of branch oil pipes;
[0009] Wherein, a plurality of oil outlets are circumferentially arranged on the outer wall of one end of the branch oil pipe connected to the slewing bearing;
[0010] The negative feedback component is arranged inside the branch oil pipe and includes a fixed disk, a pressure sensor signal-connected to an external intelligent terminal, and a sliding column sequentially arranged from the direction away from the opening of the branch oil pipe;
[0011] The sliding column is slidably connected to the fixed disk through an elastic member, so that when the sliding column is not affected by an external force, it blocks the plurality of oil outlets;
[0012] When the lubricating grease is pressurized by the lubrication pump station and outputs from the oil outlet, the sliding column just squeezes and fits with the pressure sensor.
[0013] Further, a sealing washer that fits with the inner wall of the branch oil pipe is arranged at one end of the sliding column away from the fixed disk.
[0014] Further, a one-way valve flap is arranged at the oil outlet.
[0015] Further, the oil outlet is set as a strip structure with a stepped groove.
[0016] Further, three distributors are provided, and six branch oil pipes are arranged on the same distributor.
[0017] Further, the main oil pipe is made of seamless steel pipe and is set as an arc-shaped structure.
[0018] Further, the lubrication pump station includes a hydraulic pump, an oil storage tank, and a PLC to receive the signal control of an external intelligent terminal and complete the output of the lubricating grease in the oil storage tank through the hydraulic pump.
[0019] Further, the lubrication pump station can be relatively fixed with the outer ring of the slewing bearing.
[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0021] By setting up a lubricating oil pump station, a main oil pipe, a distributor and branch oil pipes, it is possible to sequentially transport lubricating grease to the main oil pipe, the distributor and the branch oil pipes through the operation of the lubricating oil pump station. And since the branch oil pipes correspond to the lubricating points of the slewing bearing, the function of quickly and autonomously lubricating the slewing bearing is realized.
[0022] Moreover, by arranging an oil outlet on the outer side of the branch oil pipe and a negative feedback assembly including a fixed disk, a pressure sensor and a sliding column, when the lubricating grease is discharged from the oil outlet, under the pressurized state, it will push the sliding column into contact with the pressure sensor. Since the pressure sensor is connected to an external intelligent terminal, it is possible to indicate whether the lubricating grease is discharged from the oil outlet by monitoring whether the pressure sensor forms a signal. For example, when the pressure sensor does not form a signal or the duration of the formed signal is inconsistent with the duration of the signal formed in the previous normal state, it indicates that the branch oil pipe is damaged and the lubricating grease cannot be output or completely output to the designated lubricating points of the slewing bearing. At this time, the operator needs to stop the operation of the slewing bearing and repair the branch oil pipe to avoid situations such as jamming, vibration and wear of the slewing bearing during subsequent operation due to insufficient lubrication, and extend the service life of the slewing bearing.

[0029] The technical solutions of the present utility model will be described clearly and completely below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0030] Please refer to Figures 1 to 3 As shown, the first aspect embodiment of the present utility model provides a rotary bearing lubrication system for cable processing, including a lubrication pump station 1, a main oil pipe 2, a distributor 3, a branch oil pipe 4, and a negative feedback component 5.
[0031] Wherein, the output end of the lubrication pump station 1 is connected to one end of the main oil pipe 2, and the other end of the main oil pipe 2 is connected to the distributor 3.
[0032] It should be noted that the lubrication pump station 1 can be relatively fixed with the outer ring of the rotary bearing, that is, the lubrication pump station 1 is fixedly installed on a fixed platform fixed with the rotary bearing to ensure that the normal lubrication function of the lubrication pump station 1 will not be affected when the rotary bearing operates.
[0033] In addition, a plurality of branch oil pipes 4 are provided, and one end is connected to the outer ring of the rotary bearing, and the other end is connected to the distributor 3. When the lubrication pump station 1 operates, lubricating grease is output into the distributor 3 and output to a plurality of lubrication points of the rotary bearing through the plurality of branch oil pipes 4, so as to realize the lubrication function of the rotary bearing.
[0034] It should be noted that, in this embodiment, the lubrication pump station 1 includes a hydraulic pump, an oil storage tank, and a PLC to receive the signal control of an external intelligent terminal, and the lubricating grease in the oil storage tank is output through the hydraulic pump. This is a conventional technical means of the prior art, so it will not be elaborated here.
[0035] In this embodiment, the oil outlet direction of the branch oil pipe 4 is further limited, so as to know whether the lubricating grease is output from this oil outlet position to the specified lubrication point according to the cooperation between the oil outlet direction and the negative feedback component 5 for monitoring purposes, so as to ensure the normal operation of the subsequent rotary bearing.
[0036] Specifically, a plurality of oil outlets 41 are circumferentially arranged on the outer wall of the end of the branch oil pipe 4 connected to the rotary bearing.
[0037] Among them, the negative feedback component 5 is arranged inside the branch oil pipe 4, and includes a fixed disk 51, a pressure sensor 52 signal - connected to an external intelligent terminal, and a sliding column 53, which are arranged in sequence from the direction away from the opening of the branch oil pipe 4.
[0038] The fixed disk 51 is fixed inside the branch oil pipe 4 and is used to provide support for the pressure sensor 52. The sliding column 53 is slidably connected to the fixed disk 51 through an elastic member, so that when the sliding column 53 is not subject to external force, it blocks a plurality of the oil outlets 41.
[0039] Moreover, when the lubricating grease is under the pressure of the lubricating oil pump station 1 and is output from the oil outlet 41, the sliding column 53 just squeezes and fits with the pressure sensor 52, that is, the pressure sensor 52 can be pressured to form a signal and output the signal to the external intelligent terminal, thereby indicating that the lubricating grease is output from the oil outlet 41.
[0040] Correspondingly, when the branch oil pipe 4 is damaged and the lubricating grease overflows from the damaged part under the pressure of the lubricating oil pump station 1, the sliding column 53 cannot squeeze and fit with the pressure sensor 52, that is, the pressure sensor 52 cannot form a corresponding signal, thereby indicating that the lubricating grease is not output from the oil outlet 41. Therefore, at this time, the operator needs to carry out maintenance.
[0041] In addition, there is another situation. For example, when the branch oil pipe 4 has a partial damage, a part of the lubricating grease overflows from the damaged part, and the other part is output from the oil outlet 41. Since the single - time output volume of the lubricating grease remains the same, at this time, the operator can compare the duration of the signal formed by the pressure sensor 52 with the duration of the signal formed by the pressure sensor 52 in the normal output state of the lubricating grease to correspondingly identify whether the branch oil pipe 4 is damaged, so as to facilitate the operator to carry out maintenance in time.
[0042] By setting the lubricating oil pump station 1, the main oil pipe 2, the distributor 3 and the branch oil pipe 4, this device can, through the operation of the lubricating oil pump station 1, sequentially transport the lubricating grease to the main oil pipe 2, the distributor 3 and the branch oil pipe 4. And because the branch oil pipe 4 corresponds to the lubrication points of the slewing bearing, the function of quickly and autonomously lubricating the slewing bearing is realized.
[0043] Moreover, by providing an oil outlet 41 on the outer side of the branch oil pipe 4 and a negative feedback component 5 including a fixed disk 51, a pressure sensor 52, and a sliding column 53, when the lubricating grease is discharged from the oil outlet 41, under a pressurized state, it will push the sliding column 53 into contact with the pressure sensor 52. Since the pressure sensor 52 is connected to an external intelligent terminal, it is possible to indicate whether the lubricating grease is discharged from the oil outlet 41 by monitoring whether the pressure sensor 52 forms a signal. For example, when the pressure sensor 52 does not form a signal or the duration of the formed signal is inconsistent with the duration of the signal formed under normal conditions in the past, it indicates that the branch oil pipe 4 is damaged, and the lubricating grease cannot be output or completely output to the designated lubrication point of the slewing bearing. At this time, the operator needs to stop the operation of the slewing bearing and repair the branch oil pipe 4 to avoid situations such as jamming, vibration, and wear of the slewing bearing during subsequent operation due to insufficient lubrication, and extend the service life of the slewing bearing.
[0044] In this embodiment, a sealing washer 531 that fits the inner wall of the branch oil pipe 4 is provided at one end of the sliding column 53 away from the fixed disk 51 to prevent lubricating grease from entering the chamber formed by the fixed disk 51 and the sliding column 53, thus affecting the normal operation of the pressure sensor 52.
[0045] In other embodiments, such as Figure 2 and Figure 3 as shown, a one-way valve 6 is provided at the oil outlet 41, so that the oil outlet 41 is in a closed state under normal conditions, avoiding the accumulation of external impurities, etc. at the oil outlet 41, thus affecting the oil discharge effect of the lubricating grease and further affecting the lubrication of the slewing bearing.
[0046] Among them, the oil outlet 41 is set as a strip-shaped structure with a stepped groove for installing the one-way valve 6.
[0047] In a further embodiment, three distributors 3 are provided, and six branch oil pipes 4 are provided on the same distributor 3.
[0048] It should be noted that the number of branch oil pipes 4 can be specifically limited according to requirements, such as setting four or eight, etc.
[0049] Among them, the main oil pipe 2 is set as a seamless steel pipe and is set as an arc-shaped structure, which is convenient for connecting multiple distributors 3 at different positions.
[0050] The above embodiments are only used to illustrate the technical method of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
