Description

Technical Field

[0001] The present invention relates to a device for lubricating the wheel rims of railway locomotives and vehicles, and belongs to the technical field of railway wheel lubrication equipment. Background Art

[0002] During the operation of railway vehicles, friction occurs between the wheels and the tracks. On the one hand, this friction is indispensable for the wheels to run on the tracks. On the other hand, the friction between the wheels and the tracks will cause wear and tear on the wheels and the tracks. How to ensure sufficient friction between the wheels and the tracks and reduce the wear and tear of the wheels and the tracks has always been the direction of efforts in the railway transportation industry. Among the wear and tear of the wheels and the tracks, the abnormal wear of the locomotive wheel rims is more prominent. The wear of the wheels, tracks, vehicle wheel rims, and rail heads occurs synchronously. The most severely worn areas mainly occur on the inner side of the rail head of the outer rail in the curved section of the railway line. There is a certain causal relationship between the wear and the locomotive state, vehicle state, traction tonnage, running speed, curve radius, line state, etc. Especially in industrial and mining metallurgical enterprises, due to the superposition of factors such as many curves, small curves, large heavy loads, low-speed operation, and fixed-area operations in a harsh environment, the problem of abnormal wear of the wheel rims and rails becomes more prominent.

[0003] Relevant data and literature show that to reduce wheel rim wear, increasing lubrication is the most effective way to reduce wear. However, the difficulty in achieving lubrication lies in the open-air environment, the uncontrollable dynamic contact of the wheel rim-rail friction pair, which makes it difficult to form a persistent lubricating oil film and is not easy to maintain. Secondly, a large amount of oil needs to be supplied in a timely manner for lubrication when passing through curves, and lubrication is no longer required after passing, resulting in many contradictory difficulties in implementing lubrication conditions.

[0004] At present, railway locomotive wheel-rail lubrication technology has developed to a certain extent. Most designs are equipped with wheel rim lubrication devices on locomotives or vehicles, which all belong to the category of continuous oil supply or grease spraying on curves and straight lines. In actual use, it has been proven that the oil sprayers that spray oil or grease on both sides of the curve and the straight line cannot well solve the problem of wheel rim wear.

[0005] The existing wheel rim lubrication technologies mainly include two categories: carbon rod dry lubrication and grease spraying wet lubrication. The advantage of dry carbon rod lubrication is continuous lubrication, and the carbon powder does not flow and will not contaminate the tread. Its disadvantage is poor fluidity. If it is not on the contact band, it will not achieve the lubrication effect, and the lubrication effect is limited. Through actual use experience, the lubrication effect of carbon rod lubrication is not ideal in small curve radii. The advantage of wet grease spraying lubrication is good fluidity, and the grease spraying time and amount can be adjusted. Its disadvantages are that too much oil is likely to contaminate the tread of the locomotive wheel hub, the amount of oil is not easy to accurately control, and there are only grease spray nozzles at the front and rear four corners of the wheel rims, and there are no grease spray nozzles on other wheel rims. The wheel rims of the towed vehicles cannot be effectively lubricated. Once the contact surface between the vehicle wheel rim and the rail is damaged, the locomotive wheel rims will also be affected.

[0006] The existing wheel flange lubrication methods have high installation costs and large one-time investments. Each locomotive or vehicle needs to be installed, and the long-term consumption cost of special grease is high, and the later maintenance cost is also high. Moreover, it cannot solve the problem of abnormal wear of the wheel flange in the area with multiple curves and small curve radii. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide an automatic wheel flange wet lubrication device installed on the track. This lubrication device is installed in the key curve sections of the track with severe wear, and can achieve the purpose of effectively lubricating the wheel flanges of vehicles, the wheel flanges of locomotives and the rails, and can reduce investment, lower installation costs, be convenient for maintenance, and be safe and reliable.

[0008] The technical solution to solve the above technical problem is:

[0009] An automatic wheel flange wet lubrication device installed on the track, which includes an oil storage tank, an oil storage tank fixing seat, a felt core mounting seat, and a felt core. The oil storage tank is a long strip-shaped oil storage tank body, which is placed inside the rail. There is an oil storage tank fixing seat supporting below the oil storage tank, and the oil storage tank fixing seat is fixedly connected to the bottom of the rail. The upper end surface of the oil storage tank has a through lubrication opening along the length direction of the rail. The felt core mounting seat is a rectangular structure. The upper end of the felt core mounting seat is placed along the length direction of the oil storage tank outside the lubrication opening of the oil storage tank. The lower part of the felt core mounting seat is inserted into the oil storage tank from the lubrication opening at the upper end of the oil storage tank. The felt core is a rectangular felt, which is placed on the felt core mounting seat. The lower part of the felt core is located inside the oil storage tank, and the upper end of the felt core extends out of the lubrication opening at the upper end of the oil storage tank and faces the inner side of the upper rail head and the wheel flange.

[0010] For the above automatic wheel flange wet lubrication device installed on the track, the tank wall of the oil storage tank close to the inner side of the rail fits with the waist groove of the rail. The tank wall is closely attached to the inner side wall of the rail. There is a vertically upward folded edge on the side of the lubrication opening at the upper end of the oil storage tank close to the rail. The folded edge is closely attached to the lower part of the side surface of the upper rail head. The other side of the folded edge is attached to the outer surface of the felt core. There is a vertically downward folded edge on the other side of the lubrication opening at the upper end of the oil storage tank. The outer side of the felt core mounting seat leans against the outer surface of the folded edge. There is an oil filling port and a dust cover on the upper end surface of the oil storage tank. There is an oil drain valve near the bottom of the lower part of the oil storage tank. There are evenly spaced heat tracing fixing clips at the lowest part of the outer side surface of the lower part of the oil storage tank.

[0011] For the above automatic wheel flange wet lubrication device installed on the track, the oil storage tank fixing seat is made of a long strip of steel plate. One end of the strip of steel plate of the oil storage tank fixing seat is bent upward and surrounds the bottom of the oil storage tank. The other end of the strip of steel plate passes under the rail to the other side of the rail. A fixing column is welded to the other end of the strip of steel plate. The fixing column has a screw hole, and a fastening bolt passes through the screw hole of the fixing column and tightly abuts against the other side of the rail bottom.

[0012] The above-mentioned automatic wheel flange wet lubrication device installed on the track, the felt core mounting seat includes an upper mounting plate and a lower adjusting plate. The upper mounting plate is an inverted L-shaped plate. There are multiple bow-shaped elastic pieces arranged in sequence below the short plate at the upper end of the upper mounting plate. The elastic piece rivets fixedly connect the bow-shaped elastic pieces to the short plate. The two ends of the multiple bow-shaped elastic pieces press on the upper end surface of the oil storage tank. The long plate at the lower end of the upper mounting plate vertically inserts into the lubrication opening at the upper end of the oil storage tank. There are two groups of felt core height adjustment slots placed parallel left and right on the long plate surface of the upper mounting plate. The felt core height adjustment slots are 45-degree long slots, and there are multiple opening slots arranged parallel in the vertical direction at the upper part of the long slot. The lower adjusting plate is a forward-placed L-shaped plate. The long plate surface of the lower adjusting plate is parallel and opposite to the long plate surface of the upper mounting plate. Two felt core height adjustment nails are respectively fixed at both ends of the plate surface of the lower adjusting plate. The two felt core height adjustment nails are respectively opposite to the felt core height adjustment slots of the upper mounting plate. Height adjustment lifting rings are respectively connected to both ends of the lower adjusting plate. The height adjustment lifting rings are led out to the outside of the oil storage by thin iron chains. The width of the short plate surface of the lower adjusting plate exceeds the thickness of the felt core and has a small folded edge upwards to prevent the felt core from slipping off.

[0013] The above-mentioned automatic wheel flange wet lubrication device installed on the track, the felt core is a rectangular felt. The lower end of the felt core is placed on the lower short plate of the lower adjusting plate of the felt core mounting seat. One side of the lower part of the felt core leans against the long plate surface of the lower adjusting plate. The other side of the upper part of the felt core leans against the upper folded edge on the side of the upper end of the oil storage tank close to the rail. The long plate surface of the lower adjusting plate and the upper folded edge at the upper end of the oil storage tank clamp the felt core. The upper end of the felt core contacts the inner side of the upper rail head of the rail and the wheel flange. The length and thickness of the felt core match the length and width of the opening at the upper end of the oil storage tank.

[0014] The beneficial effects of the present invention are:

[0015] In the present invention, the oil storage tank is arranged inside the rail. The upper end of the felt core contacts the inner side of the upper rail head of the rail and the wheel flange. By using the gap between the wheel flange and the upper rail head of the rail, the top surface of the felt core soaked with oil is pressed by the root of the wheel flange to print oil, and the automatic oiling effect for each root of the wheel flange can be realized; the oil storage tank fixing seat can tightly connect and fix the tank body of the oil storage tank to the waist groove inside the rail; the upper mounting plate of the felt core mounting seat has inclined felt core height adjustment slots, and the felt core height adjustment nails of the lower adjusting plate can be inserted into different felt core height adjustment slots through the height adjustment lifting rings to achieve the purpose of adjusting the height of the felt core, so as to extend the service life of the felt core.

EMBODIMENT

[0023] The present invention is composed of an oil storage tank 1, an oil storage tank fixing seat 2, a felt core mounting seat 3, and a felt core 4.

[0024] Figure 1 As shown, the overall structure of the present invention is that the oil storage tank 1 is placed on the inner waist of the rail 20 and fixed by the oil storage tank fixing seat 2. The felt core mounting seat 3 is placed into the oil storage tank 1, and then the felt core 4 is placed on the felt core mounting seat 3. The felt core mounting seat 3 can adjust the height of the felt core 4 so that the upper end of the felt core 4 contacts the inner side of the upper rail head of the rail 20 and the wheel flange, and the top surface of the felt core 4 soaked with oil is rolled by the root of the wheel flange to print oil, so as to achieve automatic oiling for each root of the wheel flange.

[0025] Figure 1 and 2It is shown that the oil storage tank 1 is a long strip-shaped oil storage tank body made of thin metal plates or other materials. The oil storage tank 1 is filled with lubricating oil. There is a through lubricating opening 5 along the length direction of the rail on the upper end face of the oil storage tank 1, which is used to install the felt core mounting seat 3 and the felt core 4. The opening width of the lubricating opening 5 matches the sum of the thicknesses of the felt core mounting seat 3 and the felt core 4, which can prevent rainwater from entering.

[0026] Figure 1 、 2 It is shown that there is an upward vertical flanging 6 on the side of the lubricating opening 5 at the upper end of the oil storage tank 1 close to the rail 20. The upward vertical flanging 6 is closely attached to the side surface of the upper end rail head of the rail 20. The other side of the upward vertical flanging 6 is attached to the outer surface of the felt core 4, forming a guiding surface for the up and down movement of the felt core 4. There is a downward vertical flanging 7 on the other side of the upper end lubricating opening 5 of the oil storage tank 1. The outside of the felt core mounting seat 3 leans against the outer surface of the downward vertical flanging 7. The downward vertical flanging 7 is the guiding surface for the up and down movement of the felt core mounting seat 3.

[0027] Figure 1 、 2 It is shown that the upper end face of the oil storage tank 1 is an inclined surface, which is mainly used to prevent rainwater from flowing into the tank of the oil storage tank 1. An oil filling port and a dust-proof cover 8 are arranged on the inclined surface for filling lubricating oil and dust prevention. A drain valve 9 is arranged near the bottom surface at the lower part of the oil storage tank 1, which can be used for draining oil or discharging rainwater. A hose is connected to the drain valve 9 to realize the setting of an automatic oil replenishing device in the safe area beside the line. At the lowest part of the outer side surface of the lower part of the oil storage tank 1, heat tracing fixing clips 10 are evenly spaced and distributed, which are used to fix the heat tracing so that it closely adheres to the shell of the oil storage tank 1. Cold-proof items can be wrapped outside. This design is applicable to cold regions.

[0028] Figure 1 、 2 、3 It is shown that the oil storage tank fixing seat 2 is made of a long strip steel plate. One end of the strip steel plate of the oil storage tank fixing seat 2 is bent upward and surrounds the bottom of the oil storage tank 1. The other end of the strip steel plate passes under the rail 20 to the other side of the rail 20. A fixing column 11 is welded on the strip steel plate. The fixing column 11 has a screw hole. The fastening bolt 12 passes through the screw hole of the fixing column 11 and is tightly connected to the other side of the rail bottom of the rail 20, so that the outer wall of the oil storage tank 1 closely adheres to the groove in the waist of the rail 20. Two oil storage tank fixing seats 2 are respectively located at both ends of the oil storage tank 1 to fix the oil storage tank 1.

[0029] Figure 1 、 4 、5 It is shown that the felt core mounting seat 3 includes an upper mounting plate 13 and a lower adjusting plate 14. The upper mounting plate 13 and the lower adjusting plate 14 are made of L-shaped thin metal plates or other materials.

[0030] Figure 1 、 4As shown in FIGS. 5, the upper mounting plate 13 is an inverted L-shaped plate. Below the upper short plate of the inverted L-shaped plate, there are multiple bow-shaped elastic pieces 15 arranged in sequence. The elastic piece rivets 16 fixedly connect the bow-shaped elastic pieces 15 to the upper short plate of the upper mounting plate 13. Both ends of the multiple bow-shaped elastic pieces 16 press on the upper end surface of the oil storage tank 1. The lower long plate of the upper mounting plate 13 vertically inserts into the lubrication opening 5 at the upper end of the oil storage tank 1. The length of the upper mounting plate 13 matches the length of the lubrication opening 5 of the oil storage tank 1 and can ensure flexible up and down movement. On the long plate surface of the upper mounting plate 13, there are two groups of felt core height adjustment slots 17 placed parallel to each other left and right. The felt core height adjustment slots 17 are 45-degree long slots, and there are six stepped opening slots arranged vertically and parallel to each other at the lower part of the long slot.

[0031] Figure 1 、 4 As shown in FIGS. 5, the lower adjustment plate 14 is a forwardly placed L-shaped plate. The long plate surface of the lower adjustment plate 14 is parallel and opposite to the long plate surface of the upper mounting plate 13. At both ends of the plate surface of the lower adjustment plate 14, two felt core height adjustment pins 18 are respectively fixed. The two felt core height adjustment pins 18 are respectively opposite to the felt core height adjustment slots 17 of the upper mounting plate 13. At both ends of the lower adjustment plate 14, height adjustment lifting rings 19 led out of the oil storage tank 1 by thin iron chains are respectively connected.

[0032] Figure 1 、 4 As shown in FIGS. 5, during use, the lower adjustment plate 14 is lifted or lowered synchronously through the two height adjustment lifting rings 19, so that the two felt core height adjustment pins 18 of the lower adjustment plate 14 are respectively located in different vertical opening slots of the felt core height adjustment slots 17 of the upper mounting plate 13, and thus the height adjustment of the felt core 4 driven by the lower adjustment plate 14 can be realized. Due to the design requirement of height adjustment, the total length of the lower adjustment plate 14 is less than the total length of the upper mounting plate 13 by the horizontal translation amount of one felt core height adjustment slot 17, that is, when the lower adjustment plate 14 is at the lowest point, it aligns with the left end of the upper mounting plate 13, and when adjusted to the highest point, it aligns with the right end thereof.

[0033] Figure 1It is shown that the felt core 4 is a rectangular felt. The lower end of the felt core 4 is placed on the lower short board of the lower adjusting plate 14 of the felt core mounting seat 3. One side of the lower part of the felt core 4 leans against the long board surface of the lower adjusting plate 14, and the other side of the upper part of the felt core 4 leans against the upper folding edge 6 on one side of the upper opening of the oil storage tank 1 close to the rail 20. The long board surface of the lower adjusting plate 14 and the upper folding edge 6 of the upper opening of the oil storage tank 1 clamp the felt core 4. The upper end of the felt core 4 is in contact with the inner side of the upper rail head of the rail 20 and the wheel flange of the wheel 21. The length and thickness of the felt core 4 match the length and width of the upper opening of the oil storage tank 1. The felt core 3 is made by wrapping a wool felt with good oil absorption property with wear-resistant canvas and stapling them together with a heavy-duty stapler, or made of other materials with good oil absorption and lubrication performance to increase the durability of the felt core. The fluffy elasticity of the felt core 4 fills the lubrication opening 5 of the oil storage tank 1, which can prevent dust and rain from flowing into the oil storage tank 1.

[0034] The present invention is arranged in the last straight section before entering the curve in the key curve section with severe wear. An oil distribution device of the felt core 4 with a length exceeding the wheel circumference is arranged between the inner side of the outer rail of the curve and the wheel flange. Generally, the top surface of the felt core 4 is adjusted to be about 0.5 cm higher than the rail surface. When the train runs to the straight section before entering the curve, under the action of the rolling of the oil-saturated top of the felt core 4 by the locomotive wheel flange or the vehicle wheel flange, the gap between the flange and the rail will be filled. Similar to the principle of using a seal to dip in stamp pad ink, a small amount of lubricating grease will be stained on the contact surface of the root of the flange, achieving the effect of automatically lubricating the root of each flange passing through the outer rail 20 of the curve. During the process of the lubricating grease at the root of the flange gradually contacting the outer rail of the curve after entering the curve, an oil film is formed to achieve the purpose of indirectly lubricating the rail.

[0035] The present invention realizes the remarkable anti-wear effect of precise lubrication of the locomotive wheel flange, the wheel flange of metallurgical vehicles and the outer rail of the curve during small curve radius operation, effectively improves the transportation operation environment in the curved railway area, and avoids wheel drop repair and rail replacement during the medium repair period of locomotives and vehicles;

[0036] The present invention breaks through the thinking limitation that the traditional wheel flange lubrication device can only be installed on locomotives or vehicles. The wheel flange lubrication device is installed on the straight railway rail, so that each passing locomotive wheel flange and vehicle wheel flange can be lubricated, and unilateral lubrication of the outer rail of the curve is realized, saving grease, avoiding waste and pollution, and preventing the phenomena of over-oiling, polluting the tread of the wheel rim and ineffective lubrication;

[0037] Compared with the existing wheel-rail lubrication methods, the present invention can save a lot of device purchase costs and human and material maintenance costs, and can meet the installation requirements of different specifications of steel rails such as 50, 60, and 70. It enables long-term lubrication of all locomotive wheel flanges, special metallurgical vehicle wheel flanges, and steel rails at the same time. It has a small one-time investment, a simple structure, low maintenance costs, is easy to manufacture and implement, and the lubrication amount is proportional to the number of locomotives and trains passing through. It reduces the running resistance of locomotives and vehicles, can extend the overhaul cycles of locomotives, vehicles, and steel rails, reduces the operation cost, and has great comprehensive economic benefits.

[0039] The length of the oil storage tank 1 is 1000 mm, the width is 88 mm, and the height is 130 mm. The length of the lubrication opening 5 is 998 mm, and the width is 16 mm;
