Description

Technical Field

[0001] The present disclosure relates to the technical field of large equipment maintenance, and particularly to a lubricating spraying device and system for a crane wheel rim. Background Art

[0002] The cranes used in steel mills are key and important equipment for ensuring the smooth flow of production logistics and the safe hoisting of molten steel. A crane mainly consists of a hoisting mechanism and a traveling mechanism. The hoisting mechanism is used to lift the load, and then the traveling mechanism is used to transport the load to the required position. Wheels are the key components of the crane's traveling mechanism. Each crane has multiple wheels. Due to factors such as slight deformation of the vehicle body, displacement of the track, high usage frequency, and long transportation distance after years of use in some steel mill cranes, the crane wheels are abnormally worn. The service life of new wheels can only reach about 6 - 12 months after being put into use, which greatly increases the usage cost and maintenance cost of the crane. Therefore, research is carried out on the abnormal wear of crane wheels to find a method to solve the abnormal wear of wheels and reduce the usage cost of cranes.

[0003] Therefore, how to effectively reduce the abnormal wear of crane wheels has become an urgent problem to be solved. Summary of the Invention

[0026] As Figure 1 、 Figure 2 、 Figure 3 shown, the present invention discloses a lubricating spraying device for a crane wheel rim. The device includes: a control module and a power module. The control module includes: an integrated controller 1, a proximity switch 2, a contactor 3, and a solenoid valve 10. The power module includes: an accumulator 9. The integrated controller 1 is respectively connected to the proximity switch 2 and the contactor 3. The energization or de-energization of the contactor 3 is used to control the opening or closing of the solenoid valve 10. One end of the solenoid valve 10 is connected to the accumulator 9. Among them, When the number of wheel running circles collected by the proximity switch 2 reaches a preset number of circles, the integrated controller 1 controls the contactor 3 to be energized and closed, so that the solenoid valve 10 is opened, and the grease stored in the accumulator 9 is sprayed from the other end of the solenoid valve to the wheel rim.

[0027] Specifically, the preset number of circles can be set according to the actual working conditions, such as 100, 300, or other values. This embodiment does not make specific limitations on this. As Figure 1 shown, the proximity switch 2 is arranged at the crane wheel and is used to collect the number of wheel running circles.

[0028] Specifically, when the number of wheel running circles collected by the proximity switch 2 reaches the preset number of circles, the integrated controller 1 controls the contactor 3 to be energized and closed. After the contactor 3 is energized and closed, it controls the solenoid valve 10 to be opened, so that the grease stored in the accumulator can be sprayed from the other end of the solenoid valve to the wheel rim. It should be understood that when the number of wheel running circles collected by the proximity switch 2 does not reach the preset number of circles, the integrated controller 1 controls the contactor 3 to be disconnected, and when the contactor 3 is disconnected, it controls the solenoid valve 10 to be closed.

[0029] Through the above technical solution, the present disclosure provides a lubricating spraying device and system for the wheel rim of a crane. The lubricating spraying device for the wheel rim of the crane includes: a control module and a power module. The control module includes: an integrated controller, a proximity switch, a contactor, and a solenoid valve. The power module includes: an accumulator. The integrated controller is respectively connected to the proximity switch and the contactor. The energization or de-energization of the contactor is used to control the opening or closing of the solenoid valve. One end of the solenoid valve is connected to the accumulator. Wherein, when the number of running circles of the wheel collected by the proximity switch reaches a preset number of circles, the integrated controller controls the contactor to be energized and closed, so that the solenoid valve is opened, and the grease stored in the accumulator is sprayed from the other end of the solenoid valve onto the wheel rim. In this process, the integrated controller uses the number of running circles of the wheel collected by the proximity switch as a judgment basis. When the number of running circles of the wheel reaches the preset number of circles, the contactor is energized and closed to open the solenoid valve, so that the grease stored in the accumulator is sprayed from the other end of the solenoid valve onto the wheel rim, thereby forming an oil film layer between the wheel rim and the track, effectively playing a lubricating role and achieving the effect of reducing abnormal wear of the crane wheels.

[0030] In some alternative embodiments, the control module further includes: a pressure controller 11, and the power module further includes: an oil tank 5. One end of the pressure controller 11 is connected to the oil tank 5, and the other end of the pressure controller is connected to the integrated controller 1. Wherein, the integrated controller 1 adjusts the flow direction of the grease stored in the oil tank 5 based on the preset pressure range of the pressure controller 11 and the actual pressure value of the accumulator 9.

[0031] Specifically, the pressure controller 11 has a preset pressure range, which can be set according to the actual working conditions, and this embodiment does not make specific limitations on this. The integrated controller 1 adjusts the flow direction of the grease according to whether the actual pressure value of the accumulator 9 conforms to the preset pressure range of the pressure controller 11. Among them, adjusting the flow direction of the grease includes: the grease flows from the oil tank 5 to the accumulator 9, and the grease flows from the accumulator 9 to the oil tank 5. Thus, taking the actual pressure of the accumulator 9 and the preset pressure range of the pressure controller 11 as the judgment basis, the flow cycle of the grease is controlled by the pressure controller 11 to complete the replenishment when the grease is insufficient and the extraction when the grease is excessive.

[0032] In some alternative embodiments, the power module further includes: a pump 4. The integrated controller 1 is connected to the pump 4, and the oil tank 5 is respectively connected to the pump 4 and the accumulator 9. Wherein, in response to the actual pressure value of the accumulator 9 being lower than the preset pressure range of the pressure controller 11, the integrated controller 1 controls the pump 4 to start and pumps the grease stored in the oil tank 5 into the accumulator 9; in response to the actual pressure value of the accumulator 9 reaching the preset pressure range of the pressure controller 11, the integrated controller 1 controls the pump 4 to close.

[0033] Specifically, when the actual pressure value of the accumulator 9 is lower than the preset pressure range of the pressure controller 11, it indicates that the grease in the accumulator 9 is insufficient. In this case, the integrated controller 1 controls the pump 4 to start, and pumps the grease stored in the fuel tank 5 into the accumulator 9, thereby replenishing the grease in the accumulator 9. It should be understood that the pump 4 can be a gear pump, a vacuum pump or other pump bodies, and is specifically selected according to the actual working conditions. This embodiment does not make specific limitations on this.

[0034] Specifically, when the actual pressure value of the accumulator 9 reaches the preset pressure range of the pressure controller 11, it indicates that the grease in the accumulator 9 has been replenished and has reached the expectation. In this case, the integrated controller 1 controls the pump 4 to close, and stops replenishing the grease into the accumulator 9 to avoid an excess of grease in the accumulator 9.

[0035] In some alternative embodiments, the power module further includes a relief valve 12. The relief valve 12 is located on the connecting pipeline between the fuel tank 5 and the accumulator 9. Among them, in response to the actual pressure value of the accumulator 9 being higher than the preset pressure range of the pressure controller 11, the integrated controller 1 controls the relief valve 12 to open, so that the grease stored in the accumulator 9 flows into the fuel tank 5; in response to the actual pressure value of the accumulator 9 reaching the preset pressure range of the pressure controller 11, the integrated controller 1 controls the relief valve 12 to close.

[0036] Specifically, when the actual pressure value of the accumulator 9 is higher than the preset pressure range of the pressure controller 11, it indicates that the grease in the accumulator 9 is in excess. In this case, the integrated controller 1 controls the relief valve 12 to open, so that the grease stored in the accumulator 9 flows into the fuel tank 5, thereby reducing the grease in the accumulator 9.

[0037] Specifically, when the actual pressure value of the accumulator 9 reaches the preset pressure range of the pressure controller 11, it indicates that the grease in the accumulator 9 has been reduced and has reached the expectation. In this case, the integrated controller 1 controls the relief valve 12 to close, and stops the grease from flowing back into the fuel tank 5 to avoid insufficient grease in the accumulator 9.

[0038] In some alternative embodiments, the power module further includes: a connecting pipeline 8 and a nozzle 7. One end of the connecting pipeline 8 is connected to the solenoid valve 10, and the other end of the connecting pipeline 8 is communicated with the nozzle 7. The nozzle 7 is located at the wheel rim. Among them, in response to the solenoid valve 10 being opened, the grease stored in the accumulator 9 passes through the connecting pipeline 8 and is sprayed onto the wheel rim by using the nozzle 7.

[0039] Specifically, the connecting pipe 8 is connected to the nozzle 7, and the nozzle 7 is located at the wheel rim. When the solenoid valve 10 is opened, the grease in the accumulator 9 is conveyed through the connecting pipe 8 connected to the solenoid valve 10 to the nozzle 7, and is sprayed onto the wheel rim through the nozzle 7. At this time, the connecting pipe 8 connected to the solenoid valve 10 can be one or more, and the nozzle 7 connected to the connecting pipe 8 can be one or more.

[0040] In some alternative embodiments, the connecting pipe 8 and the nozzle 7 are used in combination. The power module includes multiple sets of connecting pipes 8 and nozzles 7. The power module further includes: a diverter 6, the diverter 6 is located on the pipeline between the connecting pipe 8 and the solenoid valve 10. One end of the diverter 6 is connected to the solenoid valve 10, and the other end of the diverter 6 is respectively connected to the connecting pipe 8 in a set of connecting pipes 8 and nozzles 7. Wherein, in response to the opening of the solenoid valve 10, the grease stored in the accumulator 9 passes through the diverter 6, and the grease is respectively conveyed to each connecting pipe 8, and is sprayed onto the corresponding wheel rim by the corresponding nozzle 7.

[0041] Specifically, when there are multiple connecting pipes 8 connected to the solenoid valve 10, a diverter 6 is provided on the pipeline between the connecting pipe 8 and the solenoid valve 10. After the solenoid valve 10 is opened, the grease in the accumulator 9 is diverted by the diverter 6, flows to each connecting pipe 8, and the grease spraying of the corresponding wheel rim is completed through the nozzle 7 corresponding to the connecting pipe 8.

[0042] In some alternative embodiments, the power module includes multiple nozzles 7. The power module further includes: a diverter 6, the diverter 6 is located on the pipeline between the connecting pipe 8 and the nozzle 7. One end of the connecting pipe 8 is connected to the solenoid valve 10, one end of the diverter 6 is connected to the connecting pipe 8, and the other end of the diverter 6 is respectively connected to each nozzle 7. Wherein, in response to the opening of the solenoid valve 10, the grease stored in the accumulator 9 is conveyed through the connecting pipe 8 to the diverter 6, and the diverter 6 respectively conveys the grease to each nozzle 7, so that the grease is sprayed onto the wheel rim.

[0043] Specifically, when there are multiple nozzles 7 connected to the connecting pipe 8, a diverter 6 is provided on the pipeline between the connecting pipe 8 and the nozzle 7. After the solenoid valve 10 is opened, the grease in the accumulator 9 flows through the connecting pipe 8, flows to the diverter 6, and under the diversion of the diverter 6, flows to each nozzle 7, thereby completing the grease spraying of the corresponding wheel rim.

[0044] It should be understood that in practical applications, there can be multiple nozzles 7 connected to the connecting pipe 8, and there can be multiple connecting pipes 8 connected to the solenoid valve 10, as Figure 1 shown, the respective contents are the same as those in the above embodiments and will not be elaborated here.

[0045] In some alternative embodiments, the integrated controller 1 determines the closing duration of the contactor 3 based on the preset number of turns of the proximity switch 2.

[0046] Specifically, the integrated controller 1 determines the closing duration of the contactor 3 based on the preset number of turns of the proximity switch 2, which means that the integrated controller 1 uses the preset number of turns set by the proximity switch 2 for data calculation to determine the closing and energizing duration of the coil in the contactor 3, thereby controlling the solenoid valve 10 to open or close.

[0047] In some alternative embodiments, in response to the closing time of the contactor 3 reaching the closing duration, the integrated controller 1 controls the contactor 3 to disconnect, so that the solenoid valve 10 closes.
