Description

Technical Field

[0001] This application belongs to the technical field of refueling equipment, specifically relating to an anti-drip refueling nozzle and refueling components. Background Technology

[0002] After prolonged operation, the wheels of the sintering trolley are prone to jamming or seizing, requiring operators to frequently lubricate the wheels to ensure smooth movement of the sintering trolley.

[0003] Currently, the lubrication nozzles used on the wheels of the sintering table are small in size, requiring the machine to be stopped so that the nozzles can be aligned with the positions on the wheels that need lubrication. This requires operators to spend a lot of time aligning the nozzles, delaying the sintering operation and reducing work efficiency. Summary of the Invention

[0004] To address the technical problem that current methods of replenishing lubricating oil to the wheels of sintering trolleys reduce the efficiency of sintering operations, this application provides a drip-proof oiling nozzle and an oiling assembly.

[0005] In a first aspect of this application, a drip-proof refill nozzle is provided, comprising: Mounting base, the mounting base having an oil drain hole; An oil inlet seat has an installation end and an oil inlet end. The installation end is disposed on the installation seat. The outer diameter of the oil inlet end increases in the direction close to the installation seat. The oil inlet seat is provided with an oil inlet hole that penetrates the installation end and the oil inlet end. The oil inlet hole is connected to the oil outlet hole. A valve body assembly is disposed at the oil inlet, and the valve body assembly is operable to open and close the oil inlet.

[0006] In some embodiments, the sidewall of the oil inlet end away from the mounting end is spherical, and the oil inlet of the oil inlet hole is located on the spherical surface.

[0007] In some embodiments, an oil baffle groove is provided in the middle of the outer ring wall of the oil inlet end.

[0008] In some embodiments, the oil inlet and the oil outlet are coaxially arranged.

[0009] In some embodiments, the minimum diameter of the mounting base is greater than the maximum diameter of the oil inlet seat, and the outer diameter of the mounting base increases in the direction away from the oil inlet seat.

[0010] In some embodiments, the oil inlet seat and the outer ring wall of the mounting seat are tapered.

[0011] In some embodiments, the diameter of the oil inlet of the oil inlet is smaller than the diameter of the oil inlet hole; the valve body assembly includes a sealing ball and a top ball spring, the top ball spring being arranged axially along the oil inlet hole, the sealing ball being disposed at the end of the top ball spring near the oil inlet hole, the diameter of the sealing ball being larger than the diameter of the oil inlet hole, and a gap for liquid medium to pass through being formed between the sealing ball and the inner wall of the oil inlet hole; when the sealing ball closes the oil inlet hole, the top ball spring is in a compressed state.

[0012] In some embodiments, the anti-drip filler nozzle also has a protective cover, one end of which is connected to the mounting base, and the other end of which at least partially surrounds the oil inlet seat.

[0013] In some embodiments, the inner ring wall of the protective cover is conical, and the inner diameter of the protective cover at one end near the oil inlet seat is larger than the inner diameter at the other end.

[0014] In a second aspect of this application, a refueling assembly is provided, including a refueling nozzle and the anti-drip refueling nozzle, wherein the refueling nozzle has an outlet, and a guide portion is provided on the periphery of the outlet to form a concave surface, and the outlet is located at the lowest point of the concave surface.

[0015] According to one or more embodiments of this application, the shape of the oil inlet end of the oil inlet seat of the anti-drip oil nozzle and oiling assembly has a guiding function. During the process of aligning the anti-drip oil nozzle with the oiling gun, the shape of the oil inlet end will cause the nozzle of the oiling gun to move and finally complete the alignment with the oil inlet end, reducing the alignment difficulty and improving the alignment efficiency. Moreover, the wheel bearing has a rotating ring and a stationary ring. When the anti-drip oil nozzle is installed on the stationary ring, even if the wheel is rotating and the stationary ring moves forward with the sintering trolley, the shape of the oil inlet end can still apply pressure to the oiling gun, thereby driving the oiling gun to move. Even if the sintering trolley is moving, lubricating oil can be smoothly injected into the wheel bearing or other rotation-related structures, realizing online lubrication, thereby improving the efficiency of sintering operation.

Detailed Implementation

[0018] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0019] The sintering trolley operates in a high-temperature environment. During operation, the trolley wheels are continuously exposed to high temperatures, causing some components of the lubricating oil in the wheel bearings and other rotation-related structures to evaporate. This can lead to wheel jamming or seizing, requiring regular replenishment of lubricating oil to ensure proper lubrication of the wheel bearings and extend wheel life. However, existing oil nozzles do not align well with the wheels, requiring operators to spend considerable time aligning and maintaining this alignment. This not only results in low oil refueling efficiency but also increases the risk of leakage due to misalignment. Therefore, this application provides a drip-proof oil nozzle to improve refueling efficiency and reduce leakage during the refueling process.

[0020] This application is described below with reference to the accompanying drawings and specific embodiments: Please see Figure 1 According to a first aspect of this application, a drip-proof fuel filler nozzle is provided, including a mounting base 5, an oil inlet seat 1, and a valve body assembly. The mounting base 5 has an oil drain hole 51, and the oil inlet seat 1 has an oil inlet hole 13 communicating with the oil drain hole 51. The valve body assembly is disposed at the oil inlet hole 13, and the valve body assembly is operable to open and close the oil inlet hole 13. The mounting base 5 and the oil inlet seat 1 are separate structural components to facilitate the installation of the valve body assembly. The drip-proof fuel filler nozzle is mounted on the wheel via the mounting base 5, and the oil drain hole 51 is connected to the location on the wheel where lubricating oil needs to be added. The opening and closing of the drip-proof fuel filler nozzle is achieved by opening and closing the valve body assembly.

[0021] The oil inlet seat 1 has a mounting end 12 and an oil inlet end 11. The mounting end 12 is disposed on the mounting base 5 to connect the oil inlet seat 1 and the mounting base 5. The outer diameter of the oil inlet end 11 increases in the direction close to the mounting base 5. The oil filling hole provided in the oil inlet seat 1 passes through the mounting end 12 and the oil inlet end 11, that is, the outer shape of the oil inlet end 11 will have a slope facing away from the mounting base 5, so that the outer diameter of the oil inlet end 11 increases in the direction close to the mounting base 5. This gives the outer shape of the oil inlet end 11 a guiding function, allowing oil to enter during the process of aligning the anti-drip oil nozzle with the oil filling gun. The shape of end 11 allows the nozzle of the oil inlet gun to move and eventually align with the oil inlet end 11, reducing the difficulty of alignment and improving the alignment efficiency. Furthermore, the wheel bearing has a dynamic ring and a stationary ring. With the anti-drip oil nozzle installed on the stationary ring, even if the wheel is rotating and the stationary ring moves forward with the sintering trolley, the shape of the oil inlet end 11 can still apply pressure to the oil inlet gun, thereby driving the oil inlet gun to move. Even if the sintering trolley is moving, lubricating oil can be smoothly injected into the wheel bearing or other rotation-related structures, realizing online lubrication.

[0022] In some embodiments, the sidewall of the oil inlet end 11 away from the mounting end 12 is spherical, and the oil inlet of the oil inlet hole 13 is located on the spherical surface. Since the distance from any point on the spherical surface to the center of the sphere is equal, when the oil gun is in contact with the anti-drip oil nozzle and the valve assembly is open, even if the angle between the oil gun and the oil inlet hole 13 is not 180°, the oil gun and the oil inlet end 11 can still maintain contact, and the oil outlet 61 of the oil gun and the oil inlet hole 13 of the oil inlet seat 1 can still maintain communication. Lubricating oil can also be smoothly pumped from the oil gun into the oil inlet hole 13, improving the operability of online lubricating oil addition and reducing oil leakage caused by asynchronous movement of the oil gun and the sintering trolley.

[0023] In some embodiments, an oil-blocking groove 14 is provided in the middle of the outer ring wall of the oil inlet end 11. The oil-blocking groove 14 is recessed towards the oil inlet hole 13 relative to the outer ring wall of the oil inlet end 11, which effectively prevents the leaked lubricating oil from moving along the outer ring wall of the oil inlet end 11 towards the mounting base 5, reducing the contamination area of ​​the leaked lubricating oil and reducing the impact on the working environment of the burning trolley during the lubricating oil addition process.

[0024] In some embodiments, the oil inlet 13 and the oil outlet 51 are coaxially arranged to reduce the machining difficulty of the mounting base 5. In other embodiments, the axis of the oil inlet 13 and the axis of the oil outlet 51 are arranged at an angle to accommodate wheels with different structures. The diameter of the oil outlet 51 is smaller than that of the oil inlet 13 to prevent parts damaged by the valve body assembly from entering the oil outlet 51, reducing the probability of damage to the anti-drip fuel nozzle. In some embodiments, a filter screen can also be installed at the oil inlet of the oil outlet 51 to further improve the probability of damage to the anti-drip fuel nozzle.

[0025] In some embodiments, the minimum diameter of the mounting base 5 is greater than the maximum diameter of the oil inlet seat 1, and the outer diameter of the mounting base 5 increases in the direction away from the oil inlet seat 1. That is, the shape of the mounting base 5 also has a slope facing away from the mounting base 5, so that the outer diameter of the mounting base 5 increases in the direction closer to the oil inlet seat 1. This makes the shape of the mounting base 5 also have a guiding function. During the process of aligning the anti-drip refueling nozzle with the refueling gun, the shape of the mounting base 5 can also move the nozzle of the refueling gun, so that the nozzle of the refueling gun gradually approaches the oil inlet end 11 and finally completes the alignment with the oil inlet end 11, further reducing the alignment difficulty and improving the alignment efficiency.

[0026] In some embodiments, the outer ring walls of the inlet seat 1 and the mounting seat 5 are tapered. This improves the alignment efficiency between the nozzle of the fuel nozzle and the inlet end 11. Of course, the outer ring walls of the inlet seat 1 and the mounting seat 5 can also be other streamlined shapes, such as spherical surfaces. The streamlined shape of the anti-drip fuel nozzle can effectively improve the smoothness of the alignment process between the fuel nozzle and the anti-drip fuel nozzle, reduce collisions, and thus reduce the possibility of the anti-drip fuel nozzle being damaged by collisions.

[0027] In some embodiments, the diameter of the oil inlet of the oil inlet 13 is smaller than the diameter of the oil inlet 13; the valve body assembly includes a sealing ball 2 and a top ball spring 3, the top ball spring 3 is arranged axially along the oil inlet 13, the sealing ball 2 is arranged at the end of the top ball spring 3 near the oil inlet, the diameter of the sealing ball 2 is larger than the diameter of the oil inlet, and there is a gap between the sealing ball 2 and the inner wall of the oil inlet 13 for the liquid medium to pass through; when the sealing ball 2 closes the oil inlet, the top ball spring 3 is in a compressed state, that is, the sealing ball 2 is controlled by the top ball spring 3 to seal the oil inlet 13. In the initial state of the anti-drip nozzle, the restoring force of the compression spring causes the sealing ball 2 to seal the oil inlet of the oil inlet 13. The top ball spring 3 installed in the oil inlet 13 can continue to be compressed in the initial state. Specifically, one end of the top ball spring 3 can be fixedly connected to the oil inlet seat 1, and the other end of the top ball spring 3 can be fixedly connected to the sealing ball 2. When the oil outlet 61 of the oil gun is aligned with the oil inlet of the oil inlet seat 1 and the oil refueling equipment connected to the oil gun starts pumping oil, the pressure value of the lubricating oil pumped out by the oil gun will act on the sealing ball 2, causing the sealing ball 2 to move towards the mounting seat 5. A gap for lubricating oil to pass through appears between the sealing ball 2 and the oil inlet of the oil inlet hole 13. After the lubricating oil passes through the oil inlet of the oil inlet hole 13, the lubricating oil will pass through the gap between the sealing ball 2 and the inner wall of the oil inlet hole 13, which allows the liquid medium to pass through, and enter the oil inlet hole 13. The diameter of the sealing ball 2 can be smaller than the inner diameter of the oil inlet hole 13 so that there is a gap between the sealing ball 2 and the inner wall of the oil inlet hole 13 for the liquid medium to pass through. Alternatively, an oil inlet groove can be opened on the outer wall of the sealing ball 2, with the length of the oil inlet groove along the direction of the oil inlet hole 13. In this case, there is a gap between the sealing ball 2 and the inner wall of the oil inlet hole 13 for the liquid medium to pass through. The diameter of the sealing ball 2 can be equal to the inner diameter of the oil inlet hole 13. In the case where the sealing ball 2 seals the oil inlet of the oil inlet hole 13, there is no gap between the oil inlet groove and the oil inlet of the oil inlet hole 13 to avoid oil leakage.

[0028] Of course, in some embodiments, the valve body assembly may also be a solenoid valve or other valve body structure capable of opening and closing the oil inlet 13.

[0029] In some embodiments, the anti-drip filler nozzle also has a protective cover, one end of which is connected to the mounting base 5, and the other end of which at least partially surrounds the oil inlet seat 1. That is, the orthogonal projection of the protective cover on the axis of the oil inlet seat 1 at least partially covers the oil inlet seat 1, so as to protect and reduce the possibility of oil leakage due to bumps and deformation of the periphery of the oil inlet seat 1, and protect the anti-drip filler nozzle.

[0030] In some embodiments, the inner ring wall of the protective cover is conical, with the inner diameter of the end of the protective cover near the oil inlet seat 1 being larger than the inner diameter of the other end. That is, the inner ring wall of the protective cover also serves as a guide for the nozzle of the refueling gun. When the nozzle of the refueling gun contacts the inner wall of the protective cover and continues to move towards the position of the oil inlet seat 1, the inner wall of the protective cover can guide the outer wall of the nozzle of the refueling gun to move and approach the oil inlet seat 1 radially, thereby enabling the nozzle to quickly align with the oil inlet seat 1 and improving alignment efficiency; and even if the sintering trolley is moving, the operator or refueling robot can quickly align under the guidance of the inner wall of the protective cover and the outer wall of the oil inlet seat 1.

[0031] In some embodiments, the mounting base 5 and the oil inlet seat 1 are connected together by a snap-fit, and a sealing gasket 4 is provided between the mounting base 5 and the oil inlet seat 1 to improve the sealing performance of the anti-drip oil nozzle. The end of the mounting base 5 away from the oil inlet seat 1 may be provided with an external thread, and the wheel is provided with an internal thread, so that the mounting base 5 is installed on the wheel by a screw connection.

[0032] Please see Figure 2 According to a second aspect of this application, a refueling assembly is provided, including an oil outlet 6 and an anti-drip refueling nozzle. The oil outlet 6 has an oil outlet 61, and a guide portion 7 is provided on the periphery of the oil outlet 61 to form a concave surface, with the oil outlet 61 located at the lowest point of the concave surface. It is understood that the oil outlet 6 is mounted on a refueling gun, and the oil outlet 61 of the oil outlet 6 also has a guide portion 7 that can guide the oil inlet end 11 of the oil inlet seat 1. The oil outlet 6 and the oil inlet seat 1 of the refueling nozzle cooperate with each other, enabling the oil outlet 61 of the oil outlet 6 and the oil inlet of the oil inlet seat 1 to quickly align, improving alignment efficiency, thereby ensuring the smooth operation of the sintering trolley within the plant area and reducing the accident rate caused by wheel jamming.
