Technical Field

The invention belongs to the field of oil tanks, and particularly relates to an automatic lubricating oil tank for an immersion type rail wheel.

Background

With the upgrading and increasing of the number of diesel locomotives and electric locomotives, the workload of vehicle maintenance is more and more. The vehicle moving platform is one of the necessary equipments for vehicle section maintenance, is arranged in or out of the vehicle section maintenance garage, and is mainly used for implementing parallel transfer operation on vehicles or bogies for maintenance operation.

The running mechanism is one of the most important parts of the transfer platform and consists of a speed reducer, running wheels and a wheel seat, wherein the running wheels run on the embedded steel rails. The running wheels are divided into driving wheels and driven wheels according to whether the speed reducer is installed or not, and are divided into edge wheels and non-edge wheels according to the geometrical shapes of the running wheels, and the edge wheels have a bearing function and a guiding function so as to ensure that the transfer platform runs along the direction determined by the steel rail.

The running wheels run on the pre-buried steel rail for a long time, and the tread and the upper plane of the steel rail, the inner side surface of the flange wheel and the outer side surface of the steel rail can generate serious abrasion, particularly the latter. The abrasion of the tread of the traveling wheel and the steel rail can influence the height of the transfer platform, the rail alignment precision in the height direction is reduced, the abrasion of the inner side face of the rim wheel and the outer side face of the steel rail can influence the running direction of the transfer platform, the transfer platform can generate large transverse swing in the running process, the transverse rail alignment precision of the transfer platform is reduced, and the transfer platform can not be used seriously. In order to reduce wear and running resistance, the running wheels and rails need to be lubricated.

At present, some vehicle moving platforms do not adopt a lubricating measure for a wheel rail, and some vehicle moving platforms adopt an automatic intermittent piston lubricating pump. The automatic intermittent piston lubricating pump is used for lubricating wheel rails automatically and intermittently, but the price is high, the oil injection quantity and the intermittent time are not easy to control, much oil injection quantity is large, waste is caused, little oil injection quantity is small, the effect is not large, the structure is complex, the oil tank is generally small, and oil is required to be added once every half month to one month.

In the figure: the oil tank comprises a tank body 1, an oil tank cover 2, a cotton thread 3, a cotton thread fixing ring 4, an elbow 5, an oil tank cover fixing block 6, an oil tank fixing block 7, an oil level indicator 8, an oil-resistant rubber pad 9, an oil filling port 10 and wear-resistant cloth 11.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without any inventive step, are within the scope of the present invention.

As shown in fig. 1 to 3, the automatic lubricating oil tank for the infiltration type rail wheel comprises a tank body 1, an oil tank cover 2, a cotton thread 3, a cotton thread fixing ring 4, an elbow 5, an oil tank cover fixing block 6, an oil tank fixing block 7 and an oil level indicator 8.

The box body 1 is a carrier of lubricating oil and is made of stainless steel or common carbon steel, because of the simple structure, the box body 1 can be made larger, the oil content is large, because the invention adopts the immersion type lubrication, the lubricating oil can be greatly saved, and the time of filling once oil can be half a year to a year.

The oil tank cap 2 is arranged above the tank body 1, the oil tank cap 3 is fixed on the tank body 1 through screws, the oil tank cap fixing blocks 6 are welded on the periphery of the inner wall of the upper portion of the tank body 1, screw holes are formed in the oil tank cap fixing blocks 6, the screws are screwed into the screw holes, oil-resistant rubber pads 9 are arranged between the oil tank cap 3 and the oil tank cap fixing blocks 6, and a sealing effect can be achieved.

The oil level indicator 8 is arranged on one side wall of the tank body 1, so that the oil quantity in the oil tank can be observed conveniently.

The oil filling port 10 is located on the oil tank cover 2 and used for filling oil into the oil tank, the oil filling port 10 is sealed through an air filter, and the air filter consists of an air filter device and an oil filling filter screen and can prevent pollution particles in the air from entering the oil tank.

The cotton thread is made by 3 stranded absorbent cotton threads, has stronger oil absorption ability, and the diameter of cotton thread 3 is between 15 ~ 20mm, and 3 afterbody circles the back of cotton thread, fixes to the solid fixed ring 4 of cotton thread that is located the box 1 bottom, and the preceding tip of cotton thread 3 is passed and is lain down freely behind the elbow 5 that is located box 1 lateral wall upper end. The outer surface of the cotton thread 3 is wrapped by a wear-resistant cloth 11 within 100mm of the front end, and the cotton thread and a plurality of strands of cotton threads are sewn together by thin threads. The rope end is in direct contact with the walking wheel, friction is generated between the rope end and the walking wheel due to rotation of the walking wheel, under the condition that lubricating oil exists, the friction force is very small, the friction loss of the multiple strands of cotton threads is also very small, however, due to long-term use, the friction loss of the multiple strands of cotton threads must be considered, the outer surface of the front end of the multiple strands of cotton threads is wrapped by wear-resistant cloth, the wear resistance of the rope end can be improved, and meanwhile the front end of the multiple strands of cotton threads can be prevented from being loose.

The lubricating oil is medium or low viscosity lubricating oil, and in order to further improve the wetting effect, 1/10-1/5 gas oil or kerosene can be added for dilution.

After the oil tank is manufactured, the oil tank is fixed on the upper plane of the wheel seat through the oil tank fixing blocks 7 arranged at two opposite side walls at two ends of the bottom of the box body 1, and due to the fact that the rim wheel has a bearing effect and a guiding effect, the tread and the inner side face of the rim wheel are worn, and therefore a lubricating oil tank is usually installed on the wheel seat with the rim wheel.

The wheel seat is previously tapped with screw holes, the oil tank fixing bolts are screwed into the screw holes, multiple cotton thread via holes are previously drilled on the wheel seat, the diameter of each hole is larger than that of each cotton thread, and the cotton threads can be loosely placed on the tread of the walking wheel after passing through the holes. 4 oil tank fixed blocks 7 are welded on the lower portion of the box body 1, waist-shaped holes are formed in the oil tank fixed blocks 7, the position of an oil tank can be transversely finely adjusted, and the ends of a plurality of strands of cotton threads are adjusted to the portions, with serious abrasion, of the walking wheels.

The invention is characterized in that the most common natural phenomenon is adopted to infiltrate lubricating oil from the bottom of an oil tank to the end parts of a plurality of strands of cotton threads, brush the lubricating oil on the tread of a traveling wheel and further brush the inner side surface of the traveling wheel. Due to the adhesiveness and the fluidity of the lubricating oil, the lubricating oil can be coated on the running rails through the running wheels, so that the running wheels and the running rails are well lubricated. After the running wheels and the running rails are lubricated, the abrasion of the rail wheels can be greatly reduced, the frictional resistance is reduced, and the working efficiency is improved. Because the weight of the transfer platform is usually more than dozens of tons, the pressure of the traveling wheels to the steel rail is very large, and after lubricating oil is added, only the friction resistance is reduced, the working efficiency is improved, and the phenomenon of slipping of the traveling wheels is avoided.
