Description

Technical Field

[0001] The utility model relates to the technical field of oiling nozzles, in particular to a flexible universal oiling device. Background Art

[0002] The sintering machine trolley is one of the important parts of the sintering machine in the steel plant. Its main function is to support and transport sintered ore. Due to the harsh working environment in the steel plant, the trolley wheel needs to withstand adverse conditions such as high temperature, high friction and heavy load, so it is necessary to add lubricating oil to the trolley wheel frequently.

[0003] Lubricating oil is added by pushing the joint at the front end of the oil delivery hose through the cylinder and inserting it into the oil delivery hole on the sintering machine trolley to add lubricating oil. Since it is inconvenient to stop the sintering machine in the steel plant to add lubricating oil after it is started, the joint at the front end of the oil delivery hose pushed by the cylinder needs to be accurately inserted into the oil delivery hole on the trolley during the movement of the sintering machine trolley. Once there is a deviation, it is easy to cause less lubricating oil to be added or even fail to add. Utility Model Content

[0004] In view of the defects existing in the prior art, the utility model provides a flexible universal oil injection device, which can solve the problem that the joint of the oil delivery hose is easily deviated when the cylinder pushes it to insert into the oil delivery hole of the sintering machine trolley, so as to facilitate the cylinder to accurately inject oil from the oil nozzle joint of the oil delivery hose into the oil delivery hole on the trolley.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A flexible universal oil injection device comprises an oil nozzle body, the oil nozzle body comprises a mounting seat, one end surface of the mounting seat is recessed inward to form a mounting groove, a through hole is provided at the bottom of the mounting groove for an oil delivery hose to pass through; a joint is provided at one end of the oil delivery hose extending into the mounting groove, a spring for installing the joint is provided in the mounting groove; an oil path is formed in the joint, and an oil outlet is formed in the oil path at the end corresponding to the joint.

[0007] Through the utility model, during the movement of the trolley wheel of the sintering machine, the cylinder pushes the mounting seat toward the trolley wheel. When the oil nozzle joint on the oil delivery hose and the oil receiving nozzle on the trolley wheel produce a range deviation, the joint on the oil delivery hose will be against the oil receiving nozzle, and the joint squeezes the spring. Due to the action of the conical spring, the joint slides into the oil receiving nozzle and squeezes the spring, so that the joint and the oil receiving nozzle fit tightly until the trolley wheel moves, so that the joint and the trolley wheel move synchronously, and the oil injection action begins. After the oil injection is completed, the cylinder brings the joint back. It effectively solves the damage and oil leakage of the oil injection equipment caused by the unstable speed of the trolley wheel, the vibration of the trolley wheel itself and the insufficient recognition accuracy of the oil gun of the oil injection equipment.

[0008] Preferably, the joint includes a nozzle joint seat connected to the oil delivery hose, the outer wall of the nozzle joint seat at one end away from the spring expands outward along the circumferential direction to form a flange, and the end of the flange away from the nozzle joint seat is provided with a nozzle connected to the nozzle joint seat and has a hemispherical shape.

[0009] Through the utility model, the oil nozzle joint seat is connected to the oil delivery hose, and when the nozzle is against the trolley wheel, the trolley wheel moves to make the nozzle gradually approach the top of the oil delivery hole. During this process, the side wall of the opening of the oil delivery hole will slide along the arc surface on the nozzle until the nozzle is inserted into the oil delivery hole, thereby facilitating the nozzle to be inserted into the oil delivery hole.

[0010] Among them, the convex arc surface of the oil nozzle joint and the concave arc surface of the oil receiving nozzle can both be hemispherical arc surfaces with basically the same arc radius. An annular sealing device can also be added to the oil outlet of the oil nozzle joint to ensure that there will be no oil leakage during the follow-up oil filling process.

[0011] Preferably, the spring is conical in shape.

[0012] According to the utility model, since the spring is tapered, the width at the opening of the installation slot is smaller, thereby facilitating the fixing of the joint; at the same time, the space between the periphery of the spring and the side wall of the opening of the installation slot is larger, which facilitates the joint to tilt under the push of the arc surface of the oil nozzle.

[0013] Preferably, the upper end of the spring is fixedly connected to the flange.

[0014] The utility model can prevent the spring from being separated from the joint.

[0015] Preferably, the joint is made of stainless steel.

[0016] Through the utility model, the stainless steel has the property of wear resistance, thereby reducing the damage caused by wear between the joint and the side wall of the oil delivery hole.

[0017] Preferably, a pressure plate is provided at the upper end of the mounting seat, and a limiting hole communicating with the mounting slot is provided on the pressure plate, and the diameter of the limiting hole is smaller than the diameter of the mounting slot.

[0018] With the utility model, the installer removes the pressing plate and then puts the spring into the installation groove, the joint extends out of the limiting hole, and the lower end surface of the pressing plate blocks the spring, thereby preventing the spring from escaping from the installation groove.

[0019] Preferably, the pressure plate and the mounting seat are connected by bolts.

[0020] According to the utility model, threaded holes are provided on the pressing plate and the mounting seat, and the installer presses the pressing plate onto the mounting seat and then fixes the pressing plate onto the mounting seat by bolts, thereby making it convenient for the installer to connect the pressing plate onto the mounting seat.

[0021] Preferably, the joint includes a joint seat and a nozzle body that cooperate with each other, and the joint seat and the nozzle body together form an oil circuit; the middle part of the oil circuit extends toward the periphery to form a first oil chamber located at the joint seat and a second oil chamber located at the nozzle body, and a first check spring is provided in the first oil chamber and the second oil chamber; the oil circuit forms a first check port at the bottom wall of the first oil chamber (531), and the first check spring is used to press a first check body at the first check port.

[0022] Preferably, the first check body is configured to be spherical, and the mating surface between the first check body and the first check opening is a spherical mating surface.

[0023] Preferably, it also includes an oil receiving nozzle for being arranged at the equipment end, the oil receiving nozzle includes an oil receiving nozzle body; the oil receiving nozzle body is used to form an interface groove on one side of the joint, and the oil receiving nozzle body is used to form an assembly part on one side of the equipment end; an oil receiving channel is formed through the interface groove and the assembly part, a third oil chamber is formed in the middle of the oil receiving channel, and a second check spring is provided in the third oil chamber; the oil receiving channel forms a second check port at the bottom wall of the third oil chamber, and the second check spring is used to press a second check body to the second check port.

[0033] Example 1

[0034] like Figure 1-4 As shown, this embodiment provides a flexible universal oil injection device, which includes an oil nozzle body 100, and the oil nozzle body 100 includes a mounting seat 110, one end of the mounting seat 110 is recessed inward to form a mounting groove 130, and a through hole 210 is provided at the bottom of the mounting groove 130 for the oil delivery hose to pass through; a joint 320 is provided at one end of the oil delivery hose extending into the mounting groove 130, and a spring 310 is provided in the mounting groove 130 to keep the joint 320 outside the mounting groove 130.

[0035] Through this embodiment, the oil nozzle 610 is fixed at the oil delivery hole position of the trolley. During the movement of the trolley of the sintering machine, the cylinder pushes the mounting seat 110 to move toward the oil nozzle on the trolley. When the oil nozzle joint 320 is tightly fitted with the oil nozzle 640 on the trolley, the joint 320 on the oil delivery hose will abut against the oil nozzle, and the joint 320 squeezes the spring 310, so that the joint 320 presses the oil nozzle until the trolley moves, so that the joint 320 moves synchronously with the trolley and the oil nozzle, and the oil injection action is completed at the same time. The spring 310 and the sealing ring 710 work together to prevent leakage during the oil injection process. The hemispherical arc surface of the joint 310 preferably solves the slight deviation of the joint 320.

[0036] In this embodiment, the convex arc surface 430 of the oil nozzle joint and the concave arc surface 640 of the oil receiving nozzle are hemispherical arc surfaces with exactly the same arc radius. An annular sealing device 710 is added to the oil outlet of the oil nozzle joint to ensure that there will be no oil leakage during the follow-up oil filling process.

[0037] In this embodiment, the connector 320 includes a nozzle connector seat 410 connected to the oil delivery hose. The outer wall of the nozzle connector seat 410 at one end away from the spring 310 expands outward along the circumferential direction to form a flange 420. The flange 420 is provided at one end away from the nozzle connector seat 410 with a nozzle 430 connected to the nozzle connector seat 410 and having a hemispherical shape.

[0038] Through this embodiment, the oil nozzle joint seat 410 is connected to the oil delivery hose, and when the nozzle 430 is against the trolley wheel, the trolley wheel moves to make the nozzle 430 gradually approach the top of the oil delivery hole. During this process, the side wall of the oil delivery hole opening will slide along the arc surface on the nozzle 430 until the nozzle 430 is inserted into the oil delivery hole, thereby facilitating the nozzle 430 to be inserted into the oil delivery hole.

[0039] In this embodiment, the spring 310 is conical in shape.

[0040] According to this embodiment, since the spring 310 is conical, the width at the opening of the mounting groove 130 is smaller, thereby facilitating the fixing of the joint 320; at the same time, the space between the periphery of the spring 310 and the side wall of the opening of the mounting groove 130 is larger, facilitating the joint 320 to tilt under the push of the curved surface of the oil nozzle.

[0041] In this embodiment, the upper end of the spring 310 is fixedly connected to the flange 420 .

[0042] Through this embodiment, the spring 310 is prevented from being separated from the joint 320 .

[0043] In this embodiment, the joint 320 is made of stainless steel.

[0044] According to this embodiment, the stainless steel has a wear-resistant property, thereby reducing the damage caused by wear between the joint 320 and the side wall of the oil delivery hole.

[0045] In this embodiment, a pressing plate 150 is provided at the upper end of the mounting seat 110 , and a limiting hole 160 communicating with the mounting groove 130 is provided on the pressing plate 150 , and the diameter of the limiting hole 160 is smaller than the diameter of the mounting groove 130 .

[0046] Through this embodiment, the installer removes the pressure plate 150 and then places the spring 310 into the installation groove 130. The connector 320 extends from the limiting hole 160. The lower end surface of the pressure plate 150 blocks the spring 310, thereby preventing the spring 310 from escaping from the installation groove 130.

[0047] In this embodiment, the pressing plate 150 is connected to the mounting seat 110 by bolts 140 .

[0048] Through this embodiment, threaded holes are provided on the pressure plate 150 and the mounting seat 110. The installer presses the pressure plate 150 onto the mounting seat 110 and then fixes the pressure plate 150 to the mounting seat 110 by bolts 140, thereby facilitating the installer to connect the pressure plate 150 to the mounting seat 110.

[0049] Example 2

[0050] See Figure 5 This embodiment also provides a flexible universal oiling device, which differs from Embodiment 1 in that:

[0051] The joint 320 includes a joint seat 510 and a nozzle body 520 that cooperate with each other. The joint seat 510 and the nozzle body 520 jointly form an oil passage 530, and the oil passage 530 forms an oil outlet at the nozzle body 520; the middle part of the oil passage 530 extends toward the periphery to form a first oil chamber 531 located at the joint seat 510 and a second oil chamber 532 located at the nozzle body 520, and a first check spring 540 is arranged in the first oil chamber 531 and the second oil chamber 532; the oil passage 530 forms a first check port 533 at the bottom wall of the first oil chamber 531, and the first check spring 540 is used to press a first check body 550 at the first check port 533. Thus, after refueling is completed, the oil in the oil circuit can be prevented from flowing out.

[0052] Furthermore, the first anti-return body 550 is configured in a spherical shape, and the mating surface between the first anti-return body 550 and the first anti-return opening 533 is a spherical mating surface, so the sealing performance is better.

[0053] Example 3

[0054] See Figure 6 This embodiment provides a refueling nozzle 600 for being arranged at the end of a device, which can be preferably matched with the refueling nozzle body 100 in Embodiment 1 or 2.

[0055] The oil receiving nozzle 600 includes an oil receiving nozzle body 610; the side of the oil receiving nozzle body 610 used to cooperate with the joint 320 forms an interface groove 640, and the side of the oil receiving nozzle body 610 used to cooperate with the equipment end forms an assembly part 650; the interface groove 640 and the assembly part 650 form an oil receiving channel 611 through the oil receiving channel 611, and the middle of the oil receiving channel 611 forms a third oil chamber, and the third oil chamber is provided with a second check spring 620; the oil receiving channel 611 forms a second check port at the bottom wall of the third oil chamber, and the second check spring 620 is used to press a second check body 630 at the second check port. Therefore, the oil in the oil circuit can be preferably outflowed.
