Description

Technical Field

[0001] The invention relates to a contact wire cleaning oiling device and a working method thereof, belonging to the field of wire material production. Background Art

[0002] The contact wire, also known as the tram wire, is an important clue that directly provides electric energy to the electric locomotive. During the operation of the train, it directly participates in the pantograph current collection with the pantograph slide plate in a high-speed sliding friction manner to complete the power transmission. At present, the contact wire can be roughly divided into: pure copper, copper-silver, copper-tin, copper-magnesium, copper-chromium-zirconium alloy contact wire, etc. Although there are many types of contact wires, their cross-sectional structures are similar, that is, the upper end of the contact wire is made with grooves on both sides for easy installation, and the lower end of the contact wire is made into an arc or plane for easy current collection.

[0003] Drawing is the last step in the production of contact wires. In order to ensure the lubrication and cooling of the wires during the drawing process, lubricating oil is often continuously injected before the wires enter the drawing die, and coolant is sprayed after the wires exit the die. Therefore, coolant, lubricating oil, granular impurities, etc. remain on the surface of the contact wires, especially in the grooves. If they are not removed thoroughly, stains, oxidation and blackening will appear during the winding and storage of the wire reels, which is unacceptable to customers and will seriously affect product sales.

[0004] In order to solve the problem of oil stains on the surface of wires, the prior art has proposed some solutions.

[0005] For example, Chinese Patent No. 201610699084.1 proposes a method for preparing a wire ultrasonic cleaning device, but its cleaning method and structure are relatively complicated.

[0006] For example, Chinese patent 201510275954.8 proposes cleaning by frictional contact of 360° between the yarn and the surface of the metal conductor, but it is not suitable for cleaning of a contact wire with a groove.

[0007] Therefore, it is urgent to develop a device with a reasonable structure that can effectively clean the contact wire surface and the groove and prevent the contact wire from oxidizing and blackening. Summary of the invention

[0008] The purpose of the present invention is to solve the problems raised in the above background issues and to provide a contact wire cleaning and oiling device and a working method thereof. The device has a compact structure, a small size, is easy to replace parts, is convenient to install, and is suitable for the continuous production of metal wires. Through the cooperation of a cleaning clamp, an air jet clamp and an oiling clamp, the contact wire surface and grooves can be effectively cleaned, and oxidation and blackening of the contact wire can be prevented.

[0009] The object of the present invention is achieved as follows: A contact line cleaning and oiling device comprises a base, on which a baffle and a support frame are arranged;

[0010] The support frame is provided with a shaft rod, which passes through the shaft holes of the cleaning clamp, the jet clamp and the oiling clamp in sequence and connects and installs the three;

[0011] The two ends of the shaft rod are provided with limit pins, and the limit pins are installed at both ends of the shaft rod to prevent the shaft rod from sliding off the support frame;

[0012] The contact line passes through the cleaning clamp, the air jet clamp and the oiling clamp in sequence according to the line entry direction;

[0013] The baffles are respectively installed at the outlet ends of the cleaning clamp, the jet clamp and the oiling clamp.

[0014] The upper end of the support frame is a circular ring structure, and the lower end is a round rod structure;

[0015] An upper spring, a lower spring and a nut are also installed on the round rod structure of the support frame. The upper spring is installed on the upper part of the base, the lower spring is at the lower part of the base, and the nut is connected and installed with the bottom end of the base.

[0016] Due to the elastic effect of the upper spring and the lower spring, it is achieved in production that the positions of the cleaning clamp, the air jet clamp and the oiling clamp vibrate and change with the vibration of the contact line.

[0017] The cleaning clamp, the air jet clamp and the oiling clamp are all composed of two parts that can be opened and closed, and are all equipped with a buckle lock. The clamp can be quickly opened and closed by switching the buckle lock.

[0018] The cleaning clip is provided with a liquid inlet hole, and a cleaning cloth is arranged on the inner surface thereof, and the cleaning liquid penetrates into the cleaning cloth through the liquid inlet hole.

[0019] The jet clamp is provided with an air inlet hole, the inside of the jet clamp is hollow, and a jet groove is opened on the inner surface.

[0020] The oiling clamp is provided with an oil inlet hole, and the inner surface is provided with an oiling cloth, and the antioxidant oil penetrates into the oiling cloth through the oil inlet hole.

[0021] The two baffles on the base located on the same plane form a group, and the side of the baffle close to the contact line touches a part of the corresponding cleaning clamp, jet clamp and oiling clamp, while maintaining a safe distance from the contact line, which can prevent the baffle from scratching the contact line.

[0022] The cross-sectional shapes of the cleaning clamp and the oiling clamp match the cross-sectional shape of the contact line, and they are respectively matched with the cleaning cloth and the oiling cloth to maintain close contact with the contact line.

[0023] The cleaning clamp, the air jet clamp and the oiling clamp are all movably mounted on the shaft rod and are evenly distributed on one side of the baffle where the contact line enters.

[0024] The base is also provided with a fixing hole.

[0025] A working method of a contact line cleaning oiling device comprises the following steps:

[0026] Step 1: Install the contact wire cleaning and oiling device in front of the contact wire take-up machine through the fixing hole, and indirectly adjust the height of the cleaning clamp, the air jet clamp and the oiling clamp by adjusting the nut on the support frame, so that the height of the three is consistent with the height of the contact wire;

[0027] Step 2: Adjust the positions of the three clamps so that they are evenly distributed on the contact line inlet side of the baffle;

[0028] Step 3: Open the corresponding buckle locks on the three clamps. When the contact line passes through the three clamps, close the three clamps with the corresponding buckle locks;

[0029] Step 4: Connect the cleaning liquid tube to the liquid inlet hole to ensure that the cleaning liquid can evenly penetrate into the cleaning cloth;

[0030] Connect the compressed air pipe to the air inlet hole and ensure that the compressed air can be ejected from the jet groove on the inner surface of the jet clamp;

[0031] Connect the oil pipe to the oil inlet hole to ensure that the antioxidant oil can evenly penetrate the oiled cloth;

[0032] Step 5: When the contact line passes through the cleaning clamp, the cleaning cloth, in cooperation with the cleaning liquid, effectively wipes off the lubricating oil, coolant and granular impurities remaining on the surface of the contact line and in the groove;

[0033] Passing through the jet clamp in sequence, the gas ejected from the jet slot makes the contact line surface clean and dry;

[0034] Then, through the oiling clamp, the oiling cloth can evenly apply the antioxidant oil on the contact line surface and in the groove;

[0035] The above-mentioned contact wire is processed by a cleaning clamp, an air jet clamp and an oiling clamp to clean the surface of the contact wire and prevent the contact wire from being oxidized and blackened.

[0036] Compared with the prior art, the present invention has the following advantages:

[0037] 1. Compact structure, small size, easy to replace parts and easy to install.

[0038] 2. The cross-sectional shapes of the cleaning clamp and the oiling clamp match the contact line, and their positions change with the vibration of the contact line. Therefore, it can ensure that the cleaning clamp and the oiling clamp are in close contact with the contact line and prevent the clamp from scratching the contact line.

[0039] 3. This device is suitable for online continuous production of metal wires. Through the cooperation of cleaning clamps, jet clamps and oiling clamps, it can not only effectively clean the contact wire surface and grooves, but also prevent the contact wire from oxidation and blackening.

[0056] Limiting pins 31 are arranged at both ends of the shaft rod 3 .

[0057] In this embodiment, the limiting pins 31 are installed at both ends of the shaft to prevent the shaft from sliding off the support frame.

[0058] The contact line 7 passes through the cleaning clamp 4, the air jet clamp 5 and the oiling clamp 6 in sequence according to the incoming line direction;

[0059] The baffles 11 are respectively installed at the outlet ends of the cleaning clamp 4, the jet clamp 5 and the oiling clamp 6.

[0069] The cross-sectional shapes of the cleaning clamp 4 and the oiling clamp 6 match the cross-sectional shape of the contact line 7 , and they are kept in close contact with the contact line 7 by cooperating with the cleaning cloth 43 and the oiling cloth 63 , respectively.

[0070] The cleaning clamp 4 , the air jet clamp 5 and the oiling clamp 6 are all movably mounted on the shaft 3 and are evenly distributed on the side of the baffle 11 where the contact wire 7 enters.

[0071] The base 1 is also provided with a fixing hole 12 to fix the base 1 .

[0072] In this embodiment, a working method of a contact line cleaning and oiling device of the present invention is as follows:

[0073] Step 1: Install the contact wire cleaning and oiling device in front of the contact wire take-up machine through the fixing hole 12, and indirectly adjust the height of the cleaning clamp 4, the air jet clamp 5 and the oiling clamp 6 by adjusting the nut 23 on the support frame 2, so that the heights of the three are consistent with the height of the contact wire 7;

[0074] Step 2: Adjust the positions of the three clamps so that they are all distributed on the same side of the baffle 11, that is, the side where the contact line 7 enters;

[0077] Step 5: When the contact wire 7 passes through the cleaning clamp 4, the cleaning cloth 43, in cooperation with the cleaning liquid, effectively wipes off the lubricating oil, coolant and granular impurities remaining on the surface and in the groove of the contact wire 7; it passes through the jet clamp 5 in turn, and the gas ejected from the jet slot 53 makes the surface of the contact wire 7 clean and dry; then it passes through the oiling clamp 6, and the oiling cloth 63 can evenly apply the antioxidant oil on the surface and in the groove of the contact wire 7;

[0078] The contact wire 7 is processed by the cleaning clamp 4, the air jet clamp 5 and the oiling clamp 6, which not only effectively cleans the surface of the contact wire 7, but also prevents the contact wire 7 from being oxidized and blackened.

[0079] The above are only specific application examples of the present invention and do not constitute any limitation on the protection scope of the present invention. Any technical solution formed by equivalent transformation or equivalent replacement shall fall within the protection scope of the present invention.
