[0002] With the development of industry, there are more and more forklifts, which are indispensable handling tools in factories. Forklifts will be damaged after long-term use and need maintenance. Maintenance requires the removal of parts in the relative parts for inspection. The most complicated one is the gearbox. The gearbox is a mechanism used to change the speed and torque from the engine. It can change the transmission ratio of the output shaft and the input shaft in a fixed or graded manner to change the power output of the forklift and change the direction of the forklift. The gearbox contains a large number of gears and shafts. After disassembly, a large amount of oil and impurities remain on the surface. The traditional cleaning method is to clean the parts with clean water, which cannot be thoroughly cleaned. During the disassembly process, the operator usually holds a brush in one hand and the disassembled gear or shaft in the other hand, and locally cleans the gears and shafts under the outlet pipe with a brush. In this process, the outlet pipe needs to continuously discharge water, and a large amount of wastewater will be generated during the cleaning process, wasting resources. In addition, due to the large number of gears and shafts in the gearbox, after disassembly, the operator holds a brush in one hand and the disassembled gear or shaft in the other hand for brushing, which increases the operating intensity of the workers and affects work efficiency.

The operator does not need to put down the disassembly tools and pick up the brush to clean the surfaces of the gears and shafts, which reduces the operator's work intensity and improves work efficiency. When the cleaning liquid is needed to clean the gears and shafts, the operator steps on the pressure sensor 5 on the pedal to apply pressure to the detection part on the top of the pressure sensor 5, so that the pressure sensor 5 detects the pressure value on the top of the pressure sensor 5, and feeds back the pressure detection signal to the controller 6. The controller 6 controls the liquid supply component to start according to the pressure detection signal, so that the liquid supply component transports the cleaning liquid to the liquid outlet pipe 25, so that the gears and shafts only flow out the cleaning liquid through the liquid outlet pipe 25 for cleaning when the cleaning liquid is needed. When the operator's foot is separated from the pressure sensor 5, the pressure sensor 5 does not detect the pressure. At this time, the controller 6 controls the liquid supply component to close, so as to avoid waste.

When the operator disassembles the gearbox, the gearbox is placed on the water filter screen 14 for disassembly. At this time, there is no obstacle on the lower side of the brush barrel 32. The infrared sensor 4 on the inner wall of the right baffle 12 detects the distance D between the inner wall of the left baffle 12 and the infrared sensor 4, where D is 150 cm, and feeds back the distance detection signal to the controller 6. At this time, the controller 6 controls the motor 31 to turn off according to the distance detection signal. When the operator needs to clean the disassembled gear or shaft, first When the gear or shaft is placed at the lower end of the brush cylinder 32, the infrared sensor 4 detects the distance d between the gear or shaft at the lower end of the brush cylinder 32 and the infrared sensor 4. At this time, d<D, and the distance detection signal is fed back to the controller 6. At this time, the controller 6 controls the motor 31 to start according to the distance detection signal, and the motor 31 drives the brush cylinder 32 to rotate, so that the bristles of the brush cylinder 32 brush the disassembled gear or shaft, and brush off the impurities on the surface of the gear and shaft. There is no need for the operator to put down the disassembly tool and pick up the brush to clean the surface of the gear and shaft, which reduces the work intensity of the operator and improves the work efficiency.

[0054] When cleaning liquid is needed to clean the gears and shafts, the operator steps on the pressure sensor 5 on the pedal to apply pressure to the detection part on the top of the pressure sensor 5, so that the pressure sensor 5 detects the pressure value on the top of the pressure sensor 5 and feeds back the pressure detection signal to the controller 6. The controller 6 controls the liquid supply pump 24 to start according to the pressure detection signal. After the liquid supply pump 24 is started, the cleaning liquid in the liquid storage tank 22 is transported to the liquid outlet pipe 25 and flows out through the liquid outlet of the liquid outlet pipe 25, so that the gears and shafts are cleaned only when the cleaning liquid is needed. When the operator's foot is off the pressure sensor 5, the pressure sensor 5 does not detect the pressure. At this time, the controller 6 controls the liquid supply pump 24 to close, thereby avoiding waste.
