Description

Technical Field

[0001] This utility model belongs to the technical field of oil change equipment and relates to an oil change device for a speed reducer. Background Technology

[0002] Commonly used equipment in the silk refining process includes high-bay warehouse logistics equipment, tube handling equipment, cabinet storage equipment, and conveying equipment. Specifically, this includes stacker cranes, EMS trolleys, robotic arms, various tube handling equipment, belt conveyors, roller conveyors, and vibrating conveyors. This type of equipment typically requires a motor to provide the conveying power. Since the motor's output speed is often very high, a speed reducer is needed to adjust the speed ratio. Speed ​​reducers are generally used in low-speed, high-torque transmission equipment. They reduce the speed of the high-speed motor by having a smaller gear on the input shaft mesh with a larger gear on the output shaft, thus meeting production requirements.

[0003] A speed reducer is an independent component consisting of gear transmission, worm transmission, or gear-worm transmission enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between the prime mover and the working machine and is widely used in modern machinery.

[0004] Taking a cigarette factory as an example, the conventional speed reducers it uses generally require oil replacement every five years or so, and it has been over ten years since its last major technological upgrade. As the service life of related production equipment increases, the maintenance and repair of speed reducers become increasingly important. During maintenance, current technology uses a combination of a metered oil nozzle and a funnel for manual oiling, which is time-consuming and labor-intensive. Furthermore, the waste oil is drained by gravity. However, due to the increasing age of the speed reducers, more and more sludge accumulates at the bottom, and gravity draining results in incomplete removal of impurities from the internal components, thus shortening the lifespan of the lubricating oil. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a speed reducer oil change device, which can solve the technical problems of the existing speed reducer using manual direct filling when adding oil, which is time-consuming and laborious, and the disadvantage of not being able to clean the impurities inside the speed reducer when draining waste oil by gravity, which leads to a shortened service life of the lubricating oil.

[0006] To solve the above-mentioned technical problems, this utility model is implemented using the following technical solution:

[0007] In a first aspect, this utility model provides a speed reducer oil change device, comprising:

[0008] The system includes a waste oil storage tank, a vacuum pump integrated into the waste oil storage tank and connected to the waste oil storage tank via a pipeline, a waste oil suction pipe extending from the inside of the waste oil storage tank to the outside of the tank, a lubricating oil tank, an oil suction pipe extending into the lubricating oil tank for oil suction, a pneumatic refueling pump connected to the oil suction pipe, a second connecting pipe connected to the pneumatic refueling pump, a metering refueling nozzle connected to the second connecting pipe, and a drive mechanism for driving the vacuum pump and the pneumatic refueling pump.

[0009] Furthermore, the drive mechanism includes:

[0010] The first connecting pipe, one end of which is connected to the compressed air pipe laid near the reducer to be changed;

[0011] An automatic telescopic hose reel, wherein both the first connecting pipe and the second connecting pipe are arranged within the drive mechanism via the automatic telescopic hose reel.

[0012] When the waste oil extraction process is implemented, the other end of the first connecting pipe is connected to the vacuum pump;

[0013] When the refueling process is carried out, the other end of the first connecting pipe is connected to the pneumatic refueling pump.

[0014] Furthermore, the air supply port of the pneumatic refueling pump integrates a pneumatic mechanism, which includes a pressure reducing valve for regulating and stabilizing the air source, a filter for filtering moisture in the compressed air, and an oil mist lubricator for lubricating the pneumatic refueling pump. The air supply port of the pneumatic mechanism is connected to the other end of the first connecting pipe.

[0015] The outlet of the pneumatic oil pump is connected to a buffer tank for stabilizing the flow of lubricating oil, and the outlet of the buffer tank is connected to the second connecting pipe.

[0016] The oil suction port of the pneumatic refueling pump is connected to the oil suction pipe, and a detachable oil receiving tank for receiving leakage from the oil suction pipe is arranged at the vertical extension end of the oil suction pipe.

[0017] Furthermore, it also includes a carrier vehicle, on which a limiting mechanism is arranged. The limiting mechanism includes a spring pin body and pin hole supports arranged on both sides of the waste oil storage tank base. When the waste oil storage tank is fixed to the carrier vehicle, the spring pin body engages with the pin hole supports.

[0018] The carrier is equipped with a fixing mechanism for limiting the displacement of the lubricating oil drum. The fixing mechanism includes a clamping member, which includes at least two telescopic screws that act on the lubricating oil drum. The carrier is also equipped with a fixing bracket for fixing the oil suction pipe.

[0019] Furthermore, the detachable oil receiving tank is made of stainless steel. The detachable oil receiving tank is attracted to the flat surface of the carrier vehicle by a strong magnet arranged on the carrier vehicle. A fireproof and flame-retardant absorbent sponge is placed outside the detachable oil receiving tank to absorb the residual lubricating oil flowing down from the outer wall of the oil suction pipe.

[0020] Furthermore, the waste oil storage tank is integrated with a display tube for real-time display of the waste oil capacity inside the tank;

[0021] The waste oil storage tank is equipped with a gas supply valve for opening and closing the gas source.

[0022] The waste oil storage tank is equipped with a negative pressure gauge for measuring the working pressure inside the vacuum pump.

[0023] Furthermore, the waste oil extraction pipe is connected to the reducer's oil inlet via oil extraction pipe fittings of different specifications. One end of the oil extraction pipe fitting is connected to the waste oil extraction pipe, and the other end of the oil extraction pipe fitting is adapted to connect to the reducer's oil inlet.

[0024] Furthermore, it also includes a discharge ball valve for discharging waste oil from the waste oil storage tank.

[0025] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0026] The drive mechanism drives a pneumatic oil pump and a vacuum pump. When performing the waste oil extraction process, the drive mechanism is connected to the vacuum pump, which provides negative pressure to extract waste oil from the reducer. When performing the oil filling process, the drive mechanism is connected to the pneumatic oil pump, which draws lubricating oil from the lubricating oil tank along the suction pipe and then injects it into the reducer through a metering nozzle. The oil changing device enables both oil filling and waste oil extraction from the reducer, saving labor costs and improving work efficiency. Furthermore, since the traditional gravity draining method is not used when extracting waste oil, it avoids the problem of incomplete removal of impurities from the reducer, thus preventing the service life of the lubricating oil.

[0027] By using oil extraction pipe joints of different specifications, the oil extraction process of reducers with oil injection ports of different specifications can be completed, and the waste oil in the reducer box can be completely extracted.

[0028] The lubricating oil drum is fixed to the refueling trolley plate by an adjustable fixing mechanism, which can accommodate and fix lubricating oil drums of different sizes. Attached Figure Description

At this point, the suction pipe 12 connected to the pneumatic refueling pump 4 is removed from the lubricating oil tank 2, and its end is placed into the detachable oil receiving tank 6 to collect any remaining lubricating oil in the suction pipe. This completes the refueling process.
