Description

Technical Field

[0001] The invention relates to the technical field of rail transportation, in particular to an oil changing device for a rail engineering vehicle. Background Art

[0002] According to the relevant maintenance procedures and manufacturer's instruction manuals of diesel shunting locomotives in urban rail transit, diesel shunting locomotives require diesel engine oil replacement every 250 hours, and gearbox oil, air compressor oil, gear oil, generator oil and other greases are replaced every 500 hours. In addition, hydraulic oil, coolant and other equipment oils (liquids) need to be replaced regularly. There are many categories, large quantities, and relatively frequent operations (at least once a year). Traditional oil change operations are mostly manual operations, following the process of emptying the old oil → replacing the filter element → filling with new oil. When emptying the old oil, it is necessary to manually lift the oil barrel in the maintenance trench to reduce oil spillage. During the process, it is also necessary to always confirm the liquid level in the barrel to avoid overflow; when refueling, it is necessary to manually lift the barrel and climb to the machine room refueling port about 1.4 meters above the rail surface to manually refuel or refill the gearbox oil in the maintenance trench.

[0032] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0033] Embodiment 1

[0034] In a typical embodiment of the present invention, reference is made to Figure 1-Figure 4 As shown, an oil changing device for a railway engineering vehicle comprises a movable flat car base 7, on which an oil receiving assembly and an oil changing assembly are provided, which are used to receive waste oil and replace new oil respectively.

[0035] like Figure 1-Figure 3 As shown, the flat car base 7 is rectangular, and four wheels are arranged at the four corners of the bottom, and the wheels are universal wheels, specifically universally adjustable silent wheels, with parking brake function. Lifting ears are arranged on the side of the flat car base, which can be conveniently lifted by a crane.

[0036] The oil receiving assembly includes an oil receiving barrel 2 mounted on the flat car base. Figure 1 As shown, a connecting pipe 5 is provided on one side of the oil receiving barrel 2, and the top and bottom ends of the connecting pipe 5 are respectively connected to the oil receiving barrel 2. The connecting pipe 5 is a transparent tubular structure to facilitate display of the waste oil level. When the waste oil level reaches the specified level, the oil collection is stopped.

[0037] An oil discharge outlet is provided at the bottom of the oil receiving barrel 2, and an oil discharge valve 6 is provided on the oil discharge outlet; a handle is provided on one side of the top of the oil receiving barrel, and the oil receiving barrel 2 is fixedly mounted on the flat car base 7. The flat car base can be moved by pushing the handle.

[0038] The oil discharge outlet is connected to the oil discharge pipeline. When the waste oil in the oil receiving barrel is full, the oil discharge valve is opened to discharge the waste oil through the oil discharge pipeline.

[0039] The top of the oil receiving barrel 2 is connected to the oil receiving funnel 1 through a telescopic sleeve. The bottom of the telescopic sleeve is connected to the top of the oil receiving barrel 2, and the top of the sleeve is connected to the oil receiving funnel 1. The telescopic sleeve is made of stainless steel and is provided with a tightening knob. When oil needs to be collected, the tightening knob is first rotated to adjust the length of the telescopic sleeve to a suitable position, and then the telescopic sleeve is tightened to collect waste oil through the oil receiving funnel 1, and the waste oil flows into the oil receiving barrel 2.

[0040] The oil change assembly includes an electric oil pump 8 and a multi-way valve 3 installed on the flat car base. The multi-way valve is provided with several passages. The first side ports of the several passages are respectively connected to the oil inlet and oil outlet of the electric oil pump 8, and the second side ports are used to connect the oil barrel and several oil filling pipelines.

[0041] like Figure 4As shown, the multi-way valve 3 includes a multi-way valve body 13, and the ports on both sides of the multi-way valve are integrated on the multi-way valve body 13 and connected through the internal passage of the multi-way valve body. The bottom of the multi-way valve body 13 is supported on the flat car base 7 through the multi-way valve seat 14.

[0042] The multi-way valve seat 14 includes a base, the top of which is connected to the multi-way valve body 13 through a support rod, and the multi-way valve body 13 is fixed on the flat car base 7 through the base. Figure 1 As shown, the multi-way valve 3 and the oil receiving barrel 2 are located at two ends of the flat car base 7, and the electric oil pump 8 is located between the multi-way valve 3 and the oil receiving barrel 2.

[0043] The left side of the multi-way valve body 13 is provided with two ports, namely the first oil outlet 9 and the second oil inlet 11 of the multi-way valve. The right side of the multi-way valve body 13 is provided with seven ports, of which the port close to the edge and corresponding to the first oil outlet 9 of the multi-way valve is the first oil inlet 10, and the first oil inlet 10 is connected to the first oil outlet 9 of the multi-way valve through the internal passage of the multi-way valve body 13. The other six ports are the second oil outlets 12 of the multi-way valve, and the six second oil outlets 12 of the multi-way valve are connected to the second oil inlet 11 through the internal passage of the multi-way valve body 13.

[0044] The first oil inlet 10 and the second oil outlets 12 of the six multi-way valves are provided with valves, and the corresponding valves are opened to form corresponding passages. The valves on the second oil outlets 12 of different multi-way valves are opened to achieve the communication between the second oil inlet 11 and the corresponding second oil outlets 12 of the multi-way valves.

[0045] The first oil inlet 10 is used to connect different oil barrels through pipelines, and the first oil outlet 9 of the multi-way valve is used to connect the oil inlet of the electric oil pump 8 through pipelines, so that the electric oil pump 8 can pump the oil in the oil barrel into the electric oil pump 8 through the first oil inlet 10 and the first oil outlet 9 of the multi-way valve in sequence. The oil outlet of the electric oil pump is connected to the second oil inlet 11 through a pipeline. The second oil outlet 12 of the multi-way valve is used to connect different oil filling pipelines, and the other end of the oil change pipeline is connected to the oil change point to realize the oil change work of different greases.

[0046] like Figure 1 As shown, at least two sets of retractable reels 4 are also included. The retractable reels 4 are arranged on the flat car base 7. The pipeline inlet ends of the two sets of retractable reels 4 are respectively connected to the two sets of multi-way valve second oil outlets 12. The pipeline outlet ends of the two sets of retractable reels are used to connect to the oil change point after the pipeline is unfolded.

[0047] Two commonly used oil circuits are separately allocated in the multi-way valve 3 and connected to the retractable reel 4 for filling commonly used greases that are difficult to control flow and have a long filling distance, such as diesel engine oil and transmission oil.

[0048] It is understandable that when draining the oil, the oil receiving barrel 2 can be drained automatically by opening the oil drain valve, or the oil drain outlet can be connected to an electric oil pump through a pipeline to achieve rapid extraction and drainage of waste oil.

[0049] The structure of the retractable reel 4 is the same as that of the fire reel. By pulling the pipeline outlet end on the reel, the pipeline can be extended, which is convenient for filling grease at a long distance.

[0050] The electric oil pump 8 of this embodiment is remotely controlled, and can be started and stopped by a single person, and is equipped with an emergency stop switch to stop the equipment in an emergency. The electric oil pump is prior art.

[0051] When the rail engineering vehicle oil changing device is working, the operator can adjust the oil receiving funnel 1 to the specified height through the telescopic oil receiving pipe (telescopic sleeve), and recover the waste oil to the oil receiving barrel 2 by gravity. The oil in the barrel can be emptied by self-draining or electric oil pump 8 and wind pressure through the oil drain valve 6; the operator can use the remote control to start and stop the electric oil pump 8 for oil filling operation through one of the single-control multi-way control valves 3; the operator can use the flat car 7 to transport the waste oil to the designated recycling place. The equipment can reduce manpower operation, liberate productivity, reduce labor intensity, have good safety, and will not harm the health of the operator.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
