[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0023] As described in the background art, due to the long-term harsh working conditions, the gearbox lubrication system is prone to the presence of fatigue wear, sludge and coking deposits. Before changing the oil, the inside of the gearbox must be flushed under high pressure to remove all the debris. Otherwise, various contaminants will cause lubrication failure, and in severe cases, even breakage of gears and bearings. Therefore, this embodiment provides a gearbox lubricating oil flushing device.

[0024] See Figures 1 to 5 This embodiment proposes a gearbox lubricating oil flushing device, including a flushing tank 1. The inner wall of the flushing tank 1 is fixedly connected to a partition 2 for dividing the internal space of the flushing tank 1. One side of the flushing tank 1 is connected to a drain pipe 3 and an inlet pipe 4, and control valves are installed on the outer surfaces of the drain pipe 3 and the inlet pipe 4.

[0025] The internal space of the flushing tank 1 can be divided into two spaces by the partition 2. The upper space is used to store the waste lubricating oil and debris extracted from the gearbox. The stored waste lubricating oil and debris can be discharged to the outside by opening the control valve on the drain pipe 3 for centralized treatment. The gearbox lubricating oil flushing fluid can be added to the lower space by opening the control valve on the inlet pipe 4. After the filling is completed, the control valve is closed to prevent the flushing fluid from leaking and being contaminated by the outside.

[0026] Each of the four corners of the bottom surface of the flushing box 1 is fixedly connected with a movable wheel 8, and every two movable wheels 8 form a group. The two groups of movable wheels 8 are symmetrically arranged with the vertical line of the flushing box 1 as the axis of symmetry. By setting the movable wheels 8, the gearbox lubricating oil flushing device can be moved easily, which can improve the convenience of use. In addition, the movable wheels 8 have a self-locking function, which can lock the position of the flushing box 1.

[0027] Two handles 12 are fixedly connected to the front of the flushing box 1. Each handle 12 is covered with a protective cover 13 on its outer surface. The handle 12 allows for convenient control of the movement direction of the gearbox lubrication device. The protective cover 13 can be made of rubber to improve the comfort of holding the handle 12. Anti-slip textures can be provided on the protective cover 13 to prevent slippage.

[0028] The end of the inlet pipe 4 furthest from the flushing tank 1 is connected to an expansion port 9. The expansion port 9 can expand the diameter of the inlet pipe 4, making it easier to add gearbox lubricating oil flushing fluid into the flushing tank 1. An observation window 10 is provided on one side of the flushing tank 1, and a transparent tempered glass is installed inside the observation window 10. Through the transparent tempered glass, it is easy to observe the remaining amount of gearbox lubricating oil flushing fluid in the flushing tank 1 so as to replenish it in time.

[0029] The outside of the flushing tank 1 is provided with a flushing assembly for flushing the gearbox lubricating oil. The flushing assembly includes a first pump body 501 and a second pump body 502 installed on the front of the flushing tank 1. The output end of the first pump body 501 and the input end of the second pump body 502 are both connected to the flushing tank 1. The input end of the first pump body 501 and the output end of the second pump body 502 are respectively connected to a first connecting pipe 503 and a second connecting pipe 505. The end of the first connecting pipe 503 away from the first pump body 501 is connected to a suction pipe 504, and the end of the second connecting pipe 505 away from the second pump body 502 is connected to a flushing pipe 506.

[0030] Insert the suction pipe 504 into the gearbox through the gearbox oil inlet, then connect the power supply to the first pump body 501 and start it to generate suction. This allows the waste lubricating oil and debris inside the gearbox to pass through the suction pipe 504, the first connecting pipe 503 and the first pump body 501 in sequence until they enter the flushing tank 1 and are stored thereafter. Once the waste lubricating oil and debris inside the gearbox have been basically extracted, remove the suction pipe 504 from the gearbox oil inlet.

[0031] A high-pressure nozzle can be installed at the front end of the flushing pipe 506. Then, the flushing pipe 506 is inserted into the gearbox through the gearbox oil inlet and the gearbox oil outlet is opened. Then, the second pump body 502 is powered on and started, which can generate suction, so that the gearbox lubricating oil flushing fluid stored in the flushing tank 1 passes through the second pump body 502, the second connecting pipe 505 and the flushing pipe 506 in sequence, until it is sprayed out from the high-pressure nozzle at the front end of the flushing pipe 506, thereby flushing the waste lubricating oil and debris remaining inside the gearbox, and then allowing the remaining waste lubricating oil and debris to be discharged through the gearbox oil outlet.

[0032] Several limiting blocks 7 are fixedly connected to the front of the rinsing box 1, and the first connecting pipe 503 and the second connecting pipe 505 are both adapted to the limiting blocks 7. The first connecting pipe 503 and the second connecting pipe 505 can be inserted into the inner wall of the limiting block 7 to achieve limiting support, so as to avoid inconvenience caused by the first connecting pipe 503 and the second connecting pipe 505 being placed in a scattered manner.

[0033] The flushing tank 1 is equipped with a heating and stirring assembly for heating and mixing the gearbox lubricating oil flushing fluid. The heating and stirring assembly includes a servo motor 601 installed on the inner wall of the partition 2 and a second rotating rod 602 rotatably connected to the flushing tank 1. The output shaft end of the servo motor 601 is fixedly connected to a first rotating rod 603 rotatably connected to the flushing tank 1. A first sprocket 604 and a first stirring blade 605 are fixedly connected to the outer surface of the first rotating rod 603. A second sprocket 606 and a second stirring blade 607 are fixedly connected to the outer surface of the second rotating rod 602. The first sprocket 604 and the second sprocket 606 are connected by chain drive. The heating and stirring assembly also includes a heating wire 608 installed on the inner wall of the flushing tank 1.

[0034] When the heating wire 608 is powered on and started, it generates heat, which heats the gearbox lubricating oil flushing fluid inside the flushing box 1. When the servo motor 601 is powered on and started, it drives the first rotating rod 603 to rotate, which in turn drives the first sprocket 604 and the first stirring blade 605 on it to rotate. Through the chain drive, the second sprocket 606 can be driven to rotate, which in turn drives the second stirring blade 607 on the second rotating rod 602 to rotate. Thus, the rotating first stirring blade 605 and the second stirring blade 607 are used to stir and mix the gearbox lubricating oil flushing fluid, so that the temperature of the gearbox lubricating oil flushing fluid is basically consistent.

[0035] Furthermore, the first stirring blade 605 and the second stirring blade 607 are arranged in a cross configuration, which can improve the stirring and mixing effect of the gearbox lubricating oil flushing fluid.

[0036] A control panel 11 is installed on the front of the flushing tank 1. By setting up the control panel 11, the electrical components in the gearbox lubricating oil flushing device can be controlled in a unified manner to improve the convenience of use. The specific installation position of the control panel 11 can be selected according to the actual use requirements to facilitate the operation and control by the operator.

[0037] The components in the accompanying drawings of this utility model are for styling reference only and are not specific dimensional standards. The specific dimensions are determined according to the actual production requirements, and the materials of each component can be replaced accordingly based on actual needs.

[0038] All electrical components in this invention are commercially available, conventional equipment known to those skilled in the art. Models can be selected or customized according to actual needs. The setting method, installation method, and electrical connection method can be easily understood by those skilled in the art by following the instructions for use, and will not be described in detail here.

[0039] Working principle: When using the gearbox lubricating oil flushing device, the heating wire 608 can be connected to the power supply and started, generating heat to heat the gearbox lubricating oil flushing fluid inside the flushing tank 1, thereby increasing the dissolution rate of oil stains inside the gearbox and improving the working efficiency of the gearbox lubricating oil flushing device. During the heating period, the gearbox oil inlet is opened, and the servo motor 601 is connected to the power supply and started, which drives the first rotating rod 603 to rotate, thereby driving the first sprocket 604 and the first stirring blade 605 to rotate. Through the chain transmission, the second sprocket 606 is driven to rotate, which in turn drives the second stirring blade 607 to rotate through the second rotating rod 602. Thus, the rotating first stirring blade 605 and the second stirring blade 607 stir and mix the gearbox lubricating oil flushing fluid, making the temperature of the gearbox lubricating oil flushing fluid basically consistent. Then, the suction pipe 504 is inserted into the gearbox through the gearbox oil inlet, and then the first... When the first pump body 501 is powered on and started, it generates suction, causing the waste lubricating oil and debris inside the gearbox to pass sequentially through the suction pipe 504, the first connecting pipe 503, and the first pump body 501 until they enter the flushing tank 1 and are stored there. This continues until the waste lubricating oil and debris inside the gearbox are basically removed. Then, the suction pipe 504 is removed from the gearbox oil inlet, and the gearbox oil outlet is unscrewed. The flushing pipe 506 is then inserted into the gearbox through the gearbox oil inlet. Next, the second pump body 502 is powered on and started, generating suction, causing the gearbox lubricating oil flushing fluid stored in the flushing tank 1 to pass sequentially through the second pump body 502, the second connecting pipe 505, and the flushing pipe 506 until it is sprayed out from the high-pressure nozzle at the front end of the flushing pipe 506. This flushes away the remaining waste lubricating oil and debris inside the gearbox, allowing them to be discharged through the gearbox oil outlet. This process cleans the gearbox and prevents it from affecting normal operation.
