Description

Technical Field

[0001] The utility model relates to a vehicle-mounted wheel rim lubrication system, in particular to a novel dry wheel rim wear-reducing lubrication device. Background Art

[0002] With the rapid development of my country's railways, the problem of load wear on locomotive wheel flanges when entering curved tracks during train operation has become increasingly prominent. Reducing wheel flange wear and extending the service life of locomotive wheel flanges has become a necessity for locomotives to install wheel flange lubrication devices.

[0003] Dry lubrication is a new approach to wheel flange lubrication and represents the future development of wheel flange lubrication materials. Compared to liquid grease, dry lubrication is not restricted by harsh climates such as wind, sand, and low temperatures. It offers numerous advantages, including high compressive strength, strong adhesion, outstanding long-term performance, a low coefficient of friction, good wear resistance, and no accelerated rail shedding or pollution to the locomotive or the environment.

[0004] However, due to the harsh operating environment of trains and the unreasonable structural setting of existing dry lubrication devices, sand and other debris cannot be discharged in time after entering the lubrication device, causing the lubricating rod to get stuck. Utility Model Content

A sand discharge structure is provided between the lubricating rod and the cylinder to prevent sand particles from getting stuck between the lubricating rod and the cylinder.

[0010] In the above structure, the lubricating rod has a square cross-section, and the sand removal structure includes inclined surfaces at the four corner points of the lubricating rod; air holes are provided on both sides of the cylinder, and the gap between the inner wall of the cylinder and the lubricating rod is ensured to be no less than 3mm.

[0011] In the above structure, the elastic element includes a blocking portion, and the blocking portion includes an end plate.

A horizontal plate is provided on the top of the end plate, and the connecting portion and the horizontal plate are inserted into the interior of the cylinder; a coil spring is also provided, and the coil spring and the end plate are respectively fixed at both ends of the horizontal plate. During installation, the spring coil formed by the coil spring plate is pushed by the lubricating rod, so that the spring coil moves toward the end plate, and at the same time, the spring coil forms a thrust on the lubricating rod.

[0012] In the above structure, the connecting part of the elastic element is provided with a first connecting hole, and a second connecting hole is provided on the cylinder corresponding to the first connecting hole.

[0021] This application provides a novel dry-type wheel rim anti-friction lubrication device. A sand removal structure is provided between the lubricating rod and the barrel to prevent sand particles from becoming stuck between the lubricating rod and the barrel. Air holes are provided on both sides of the barrel to accelerate the removal of sand particles from the lubricating device by utilizing the wind speed generated by train operation, ensuring smooth operation and lubrication of the lubricating rod. This device solves the problem of sand particles easily becoming stuck between the lubricating rod and the barrel in the prior art. A coil spring is used to apply force to the lubricating rod, avoiding the sticking problem of conventional springs and increasing its service life. The device can also continuously provide sufficient and constant thrust to the lubricating rod within a confined space and working range, solving the sticking problem of conventional springs in the prior art. The elastic element is fixed in a butterfly screw with a cotter pin at the end. The butterfly screw can be tightened manually, making it easier to use and more stable. This solves the problem of conventional fixing methods using a pin shaft and a cotter pin, which lacks safety assurance and can cause the elastic element to fall off and become inoperable if the cotter pin falls due to aging or external impact.

[0022] The following further describes this implementation case with reference to the accompanying drawings:

[0023] Depend on Figure 1 — Figure 5 It can be seen that the present application includes a cylinder 1, which is a square hollow structure. A connecting plate 2 is provided above the cylinder 1. The width of the connecting plate 2 is greater than the width of the cylinder 1. The connecting plate 2 is provided with a long hole 210 on each side of the cylinder 1. An elastic element 3 is provided, and the elastic element 3 is fixedly connected to one end of the cylinder 1. A lubricating rod 4 is provided, and the lubricating rod 4 is installed inside the cylinder 1, and one end thereof abuts against the elastic element 3. The elastic element 3 keeps the lubricating rod 4 in real-time close contact with the locomotive wheel rim. A sand removal structure is provided between the lubricating rod 4 and the cylinder 1 to prevent sand particles from getting stuck between the lubricating rod 4 and the cylinder 1. In this embodiment, a sand removal structure is provided between the lubricating rod 4 and the cylinder 1 to prevent sand particles from getting stuck between the lubricating rod 4 and the cylinder 1.

[0024] Based on the above embodiments, this embodiment preferably discloses a specific embodiment of a sand removal structure. The lubricating rod 4 has a square cross-section and includes inclined surfaces 410 at each of the four corners of the lubricating rod 4. Air holes 110 are provided on both sides of the cylinder 1, and a gap of at least 3 mm is ensured between the inner wall of the cylinder 1 and the lubricating rod 4. On the one hand, the inclined surfaces 410 at the four corners of the lubricating rod 4 allow sand to enter the cylinder 1 more easily, as the space at the inclined surfaces 410 is large and less prone to blockage. On the other hand, the air holes 110 allow air generated during train operation to enter the cylinder 1 through the air holes 110, blowing the sand away and accelerating its removal. In this embodiment, the dimensions of the inclined surfaces 410 at the four corners of the lubricating rod 4 are preferably 2.5 mm x 63.4°.

[0025] On the basis of the above embodiment, preferably, the elastic element 3 includes a blocking portion, and the blocking portion includes an end plate 310. A connecting portion 320 is provided on one side of the end plate 310, and a hand-held portion 330 is provided on the other side. The hand-held portion 330 is provided to facilitate operation by the staff. A horizontal plate 340 is provided on the top of the end plate 310, and the connecting portion 320 and the horizontal plate 340 are inserted into the cylinder 1. The elastic element is also provided with a coil spring 5, and the coil spring 5 and the end plate 310 are respectively fixed at both ends of the horizontal plate 340. During installation, the spring coil 501 formed by the spring plate of the coil spring 5 is pushed by the lubricating rod 4, so that the spring coil 501 moves toward the end plate 310, and at the same time, the spring coil 501 forms a thrust on the lubricating rod 4. The use of the coil spring 5 instead of the ordinary spring in the prior art solves the problem of ordinary spring jamming and continuously provides sufficient constant thrust for the lubricating rod 4.

[0026] Based on the above embodiment, preferably, the connection portion 320 of the elastic element 3 is provided with a first connection hole 321, and a second connection hole is provided on the barrel 1 corresponding to the first connection hole 321. The second connection hole passes through the barrel 1, and a nut 6 is fixed coaxially with the second connection hole on one side of the barrel 1. A butterfly screw 7 passes through the second connection hole and the first connection hole 321 and is connected to the nut 6 to fix the connection portion 320. The butterfly screw 7 is provided with a disc ear 701 at one end and a circular hole at the other end, and a cotter pin 8 is provided in the circular hole. A cotter pin 8 is provided at the end of the butterfly screw 7. The butterfly screw 7 can be tightened by hand, which is convenient to use and makes the structure more stable. This solves the problem in the prior art of using a pin shaft and a cotter pin 8 for fixation, which cannot ensure safety. When the cotter pin 8 falls off due to aging or external impact, the elastic element 3 will fall off and become ineffective.
