Description

Technical Field

[0001] This utility model relates to the field of cableway maintenance technology, and in particular to an automatic wire rope oiling machine. Background Technology

[0002] As the core load-bearing and traction component of a cableway system, the safety and durability of the steel wire rope directly affect the operational safety of the entire system. Cableway traction cables are exposed to the outdoor environment for extended periods, enduring high temperatures, heavy loads, and complex weather conditions. The continuous movement and tension between the internal steel wires and strands generates intense friction, easily leading to wear, corrosion, and even wire breakage. Therefore, effective lubrication of the traction cable to reduce internal friction and wear with pulleys is a crucial measure to ensure its safe operation and extend its service life.

[0003] Currently, there are two main methods for lubricating and maintaining cableway traction cables: one is relying on manual periodic application, and the other is using simple automatic oil-drip devices. Manual lubrication has drawbacks such as low efficiency, high risk, and arbitrary use of lubricant, and it is difficult to ensure that the grease effectively penetrates into the rope strands. While existing automatic lubrication devices can achieve continuous or timed oil supply, they have significant shortcomings in control precision and lubrication effect.

[0004] First, in terms of oil quantity control, existing technologies generally suffer from a lack of precision. Excess grease adhering to the surface of the wire rope may cause the traction cable to slip on the drive wheel, resulting in a decrease in the anti-slip force of the cable grip. At the same time, grease will contaminate the linings of the large wheel and the support cable wheel, accelerating their aging and corrosion, and may even cause the plastic guide wings of the cable grip to stick to the wire rope, as well as contaminating the carriage and support components.

[0005] Secondly, in terms of lubrication methods, traditional methods are difficult to achieve deep penetration. Whether it is manual brushing or simple dripping, the lubricant can only cover the surface of the wire rope. It cannot effectively overcome the viscosity of the grease and force it into the tiny gaps between the strands and the wires under complex field conditions. This results in the wire rope always being in a "short oil" state, and its core friction parts are not effectively protected. The fundamental purpose of lubrication has not been achieved.

[0006] Therefore, we propose an automatic wire rope oiling machine to solve the existing problems. Utility Model Content

[0007] The purpose of this invention is to address the problems existing in the background technology by proposing an automatic wire rope oiling machine.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an automatic wire rope oiling machine, comprising a machine body and a support frame, wherein an oil storage tank and a control unit are provided on the machine body, and the oil outlet of the oil storage tank is connected to the oiling mechanism through a metering pump and an oil pipe;

[0009] The machine body is also equipped with an electromagnetic sensor for detecting the top of the wire rope strands via a cable. The electromagnetic sensor and the oiling mechanism are mounted on the bracket. The electromagnetic sensor and the metering pump are both electrically connected to the control unit. The control unit is configured to control the metering pump to pump a predetermined amount of oil calculated based on the wire rope parameters to the oiling mechanism according to the detection signal of the electromagnetic sensor.

[0010] Preferably, the oiling mechanism includes a rubber seat fixedly mounted on a bracket, a cylindrical body fixedly mounted on the rubber seat, an opening on the upper side of the cylindrical body fixedly connected and communicating with the oil pipe, and a brush unit detachably mounted on the bottom opening of the cylindrical body.

[0011] Preferably, a screw ring is rotatably provided on the brush unit, the screw ring is threaded into the outer wall of the cylinder, and a sealing ring is provided between the screw ring and the cylinder.

[0012] Preferably, a vibration motor is fixedly installed on the outer wall of the top end of the cylinder.

[0013] Preferably, the vibration motor is electrically connected to the control unit, which is configured to: when the electromagnetic sensor detects the top of the wire rope strand, start and set the vibration mode of the vibration motor according to the wire rope parameters, and simultaneously start the metering pump.

[0014] Preferably, a base frame is fixedly provided on the bottom surface of the oil storage tank, and the base frame is fixedly provided on the machine body.

[0015] Preferably, a back plate is fixedly provided on the body, and the upper end of the back plate is provided with a long sliding opening for adjusting the installation position.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention utilizes the precise identification of the top of the wire rope strand by an electromagnetic sensor and the coordinated action of a control unit. The device can accurately pump a predetermined amount of oil according to the parameters of the wire rope, ensuring that the amount of lubricant is always within the optimal range. This effectively avoids a series of serious drawbacks that seriously affect the safe operation of the cableway, such as the wire rope slipping on the drive wheel, the decrease in the anti-slip force of the cable clamp, the corrosion of the wheel lining, the sticking of parts, and environmental pollution caused by excessive oiling.

[0018] The device integrates a vibration motor that drives the oil-soaked brush bristles to generate high-frequency micro-amplitude vibration, forming a "hammering-penetration" effect. This dynamic lubrication method can strongly overcome the surface tension of the grease, forcibly squeezing the lubricant into and filling the tiny gaps between the strands and wires, effectively protecting the internal contact surfaces, significantly reducing the risk of early failure of the wire rope due to internal friction, wear and corrosion, and greatly extending its service life under harsh working conditions such as high temperature and heavy load.

[0019] The control unit can adaptively adjust the frequency and amplitude of the vibration motor or adjust the oil supply strategy according to the parameters of the wire rope. For example, it can enhance the penetration force when the load is low and heavy, and ensure uniform coverage when the load is high. This flexible adjustment allows the device to flexibly cope with various operating conditions of the cableway and always maintain the best lubrication effect. Attached Figure Description

[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] Example 1

[0029] like Figures 1-5As shown, this utility model proposes an automatic wire rope oiling machine, comprising a body 1 and a support 9. The body 1 serves as the supporting foundation, and a back plate 2 is fixedly installed on the body 1. An elongated sliding opening at the upper end of the back plate 2 is used for adjusting the installation position of subsequent components. An oil storage tank 3 is securely installed on the body 1 via a base frame 5 on its bottom surface, and is used to store lubricating oil. The oil outlet of the oil storage tank 3 is connected to a metering pump 10, which is responsible for accurately outputting a predetermined amount of oil.

[0030] Oil is delivered from metering pump 10 to oiling mechanism 7, which performs the lubrication task, via oil pipe 4. An electromagnetic sensor 8, which detects the top of the wire rope strands, is powered and communicates via cable 6. It is mounted on a bracket 9 together with oiling mechanism 7, which is installed in a designated position by locking bolts.

[0031] The machine body 1 also integrates a control unit. The electromagnetic sensor 8 and the metering pump 10 are both electrically connected to the control unit. The core function of the control unit is that it can receive the detection signal of the top of the wire rope strand sent by the electromagnetic sensor 8, and then send an instruction to the metering pump 10 to control it to pump a precise, predefined amount of oil to the oiling mechanism 7, thereby realizing on-demand and quantitative automated lubrication.

[0032] Preferably, the control unit can pre-store various wire rope parameters (structure, diameter, rope length, running speed, and average working time), and can calculate and set the single oil application amount of the metering pump 10 according to the selected parameters, thereby achieving precise control and adaptive adjustment of lubrication.

[0033] The specific structure of the oiling mechanism 7 is as follows: a rubber seat 701 is fixed on the bracket 9 as an elastic element, and a cylinder 702 is fixedly installed on the rubber seat 701. The opening on the upper side of the cylinder 702 is fixedly connected to and communicates with the oil pipe 4 to receive lubricating oil from the metering pump 10. The bottom opening of the cylinder 702 is used to install a replaceable brush unit 704.

[0034] To achieve convenient and reliable sealed installation of the bristle unit 704, a screw ring 705 is rotatably installed in its structure. This screw ring 705 engages with the outer wall of the cylinder 702 through threads. By rotating the screw ring 705, the bristle unit 704 can be pressed or removed. At the same time, a sealing ring is provided at the joint between the screw ring 705 and the cylinder 702 to effectively prevent lubricating oil from leaking from the connection.

[0035] To significantly improve lubrication, a vibration motor 703 is fixedly installed on the top outer wall of the cylinder 702. This vibration motor 703 is also electrically connected to the control unit. The control unit is configured to: when the electromagnetic sensor 8 detects the top of the wire rope strand, first calculate the optimal vibration mode based on the pre-stored wire rope parameters, then start the metering pump 10 to pump oil, and simultaneously start the vibration motor 703 in the set mode.

[0036] Furthermore, the vibration motor 703 is a variable frequency motor. The control unit can adjust the vibration frequency of the motor according to the parameters of the wire rope (structure, diameter, rope length, running speed and average working time). For example, when dealing with thick ropes and low-speed conditions, a higher amplitude and lower frequency vibration mode can be used to ensure the penetration of lubricating oil; while when dealing with thin ropes and high-speed conditions, a lower amplitude and higher frequency vibration mode is used to ensure uniform coverage of the lubricating oil film.

[0037] Working principle:

[0038] When the wire rope is running, the electromagnetic sensor 8 detects its surface in real time and accurately identifies the arrival of the top of the wire rope strand. The control unit immediately starts the metering pump 10 and the vibration motor 703 in sync. The metering pump 10 pumps a fixed amount of lubricating oil into the cylinder 702 through the oil pipe 4 to wet the brush unit 704.

[0039] Meanwhile, the vibration generated by the vibrating motor 703 is transmitted to the brush unit 704 through the cylinder 702, causing the brush bristles to vibrate at high frequency while pressing against the surface of the wire rope. This vibration produces multiple beneficial effects: First, the vibrating bristles can effectively overcome the surface tension of the lubricating oil, "hammering" and "squeezing" it into the gaps between strands and bristles inside the wire rope, achieving deep lubrication; Second, the vibration helps to break through the oxide layer and old oil stains on the surface of the wire rope, allowing the new oil to fully contact the clean metal substrate, improving lubrication efficiency; Third, the vibration promotes the formation of a uniform and strongly adhesive oil film on the surface of the wire rope, preventing oil accumulation or the appearance of lubrication gaps.

[0040] It should be noted that the vibration motor 703, electromagnetic sensor 8, metering pump 10 and control unit are existing mature technologies, and their working principles and internal structures are known to those skilled in the art. This utility model only utilizes their functions and does not improve their internal structures. Therefore, they will not be described in detail here. Those skilled in the art can select and configure them according to their needs.

[0041] The above specific embodiments are merely several preferred embodiments of this utility model.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
