[0040] As Figures 1-6 Indicated, the present embodiment provides a kind of locomotive wheel pie cleaning equipment, including shell 100 and rotating table type conveying device 200.

[0041] Shell 100 is internally provided with feeding area 101, cleaning area 102, rinsing area 103, drying area 104 and discharging area 105.

[0042] A rotary table conveyor 200 is disposed inside the housing 100. The rotary table conveyor 200 includes a shifting rotary table 1 and five clamping connectors 2. The five clamping connectors 2 are spaced apart circumferentially on the outer circumferential surface of the shifting rotary table 1. Each clamping connector 2 extends radially outward from the shifting rotary table 1. Each clamping connector 2 can extend into and clamp the center hole of the wheel disc 300, and the central axis of the clamping connector 2 is collinear with the central axis of the corresponding wheel disc 300. The conveyor includes a feeding area 101, a cleaning area 102, and a rinsing area. Area 103, drying area 104 and unloading area 105 are arranged around the outer periphery of the shifting turntable 1. The shifting turntable 1 can rotate around the vertical axis and drive the clamping joint 2 to rotate together, so that the wheel cake 300 can enter the cleaning area 102, rinsing area 103, drying area 104 and unloading area 105 in sequence from the loading area 101 as the shifting turntable 1 rotates. The wheel cake 300 can be cleaned, rinsed and dried in the cleaning area 102, rinsing area 103 and drying area 104 respectively.

[0043] by Figure 2 Taking the orientation as an example, the rotation of the displacement turntable 1 around the vertical axis is the position of the displacement turntable 1 in the vertical axis. Figure 2 The orientation shown is rotated counterclockwise. In addition, the clamp 2 extends radially outward, and the central axis of the clamp 2 is collinear with the central axis of the corresponding disc 300. Therefore, the disc 300 is placed vertically when it is clamped to the clamp 2.

[0044] In practice, in the initial state, all five clamping joints 2 of the locomotive wheel cake cleaning equipment are empty, and each of the feeding area 101, cleaning area 102, rinsing area 103, drying area 104, and unloading area 105 has one clamping joint 2. When cleaning begins, the wheel cake 300 to be cleaned is first clamped into the clamping joint 2 in the feeding area 101, and the shifting turntable 1 is started to rotate. As the shifting turntable 1 rotates, the wheel cake 300 clamped in the feeding area 101 can rotate sequentially to the cleaning area 102, rinsing area 103, and drying area 104, and finally reach the unloading area 105. At this time, the wheel cake 300 has successively undergone the cleaning, rinsing, and drying processes. After reaching the unloading area 105, the cleaned wheel cake 300 can be unloaded.

[0045] And, the locomotive wheel pie cleaning device can clean multiple wheel pies 300 at a time. While the first wheel pie 300 clamped in the loading area 101 rotates to the cleaning area 102, the empty clamp 2 initially located in the unloading area 105 rotates to the loading area 101, and at this time, the second wheel pie 300 to be cleaned can be clamped to the empty clamp 2, and so on. The locomotive wheel pie cleaning device can perform a pipeline cleaning operation on multiple wheel pies 300 at a time, and the variable-position rotating table 1 is responsible for intermittent step-by-step conveying, so that the five functions of loading, cleaning, rinsing, drying, and unloading are synchronized.

[0046] Optionally, the operation cycle of the five functions of loading, cleaning, rinsing, drying, and unloading is set to 110s, and the variable-position rotating table 1 rotates forward once in 7s.

[0047] Specifically, as shown in Figure 2 , the five clamps 2 are uniformly arranged along the circumference of the variable-position rotating table 1, and correspondingly, the loading area 101, the cleaning area 102, the rinsing area 103, the drying area 104, and the unloading area 105 are also uniformly distributed along the outer periphery of the variable-position rotating table 1. Thus, the variable-position rotating table 1 rotates 72° each time, and all the wheel pies 300 are synchronized to switch one function position.

[0048] The locomotive wheel pie cleaning device provided in the embodiment realizes a pipeline cleaning operation on multiple wheel pies 300 by setting the rotating table type conveying device 200, and the five functions of loading, cleaning, rinsing, drying, and unloading can be synchronized, which is beneficial to improve the cleaning efficiency of the device and is suitable for batch cleaning of multiple wheel pies 300, effectively meeting the needs of large-scale production. In addition, the wheel pie 300 is vertically placed on the rotating table type conveying device 200, avoiding the problem of water accumulation in the cleaning and rinsing process due to horizontal placement, thereby reducing the corrosion and wear of the clamp 2 caused by water accumulation, and being beneficial to reduce the wear and failure rate of the device.

[0049] Optionally, as shown in Figure 3 and Figure 4 , the clamp 2 has a structure with three clamping jaws, and the three clamping jaws can be stably clamped in the center hole of the wheel pie 300.

[0050] As shown in Figure 1 and Figure 5As shown, in some embodiments, the locomotive wheel pie cleaning device further comprises two translation trolleys 600, the side of the feeding area 101 and the discharging area 105 are both open, one translation trolley 600 partially extends into the feeding area 101 for feeding, and the other translation trolley 600 partially extends into the discharging area 105 for discharging. The translation trolley 600 comprises a trolley frame 601 and a carrying frame 602, the carrying frame 602 is movably connected to the trolley frame 601, and the carrying frame 602 is used for carrying the wheel pie 300 and can move close to or away from the corresponding clamping joint 2.

[0051] The carrying frame 602 moves close to the corresponding clamping joint 2 only when feeding or discharging is needed, and during the rest period, the carrying frame 602 is on the side of the trolley frame 601 away from the clamping joint 2. Specifically, when feeding in the feeding area 101, the wheel pie 300 is first placed on the carrying frame 602, and then the carrying frame 602 moves with the wheel pie 300 to move close to the clamping joint 2 in the feeding area 101, the clamping joint 2 acts on the center hole of the wheel pie 300 and clamps the wheel pie 300, and then the carrying frame 602 moves back to the side of the trolley frame 601 away from the clamping joint 2 for the next feeding. When discharging in the discharging area 105, after the cleaned wheel pie 300 reaches the discharging area 105, the carrying frame 602 moves close to the clamping joint 2 in the discharging area 105, so that the clamping joint 2 releases the cleaned wheel pie 300 and the wheel pie 300 falls on the carrying frame 602, and then the carrying frame 602 moves the wheel pie 300 out of the discharging area 105.

[0052] Through such a design, the carrying frame 602 is movably connected to the trolley frame 601 and can move close to or away from the corresponding clamping joint 2, and the carrying frame 602 can effectively ensure the stable and rapid loading or unloading of the wheel pie 300, while reducing manual intervention and labor intensity.

[0053] Further, the carrying frame 602 comprises a moving part 6021, a vertical rod 6022 and a carrying part 6023, the moving part 6021 is slidingly connected to the trolley frame 601 and can move close to or away from the corresponding clamping joint 2, the vertical rod 6022 is arranged on the top surface of the moving part 6021 and extends in the vertical direction, and the carrying part 6023 is movably connected to the vertical rod 6022 and can be lifted relative to the vertical rod 6022, and the carrying part 6023 is used for carrying the wheel pie 300.

[0054] Through such a design, the height of the carrying part 6023 can be flexibly adjusted by its own lifting, so as to realize the height alignment with the clamping joint 2 and ensure the accurate loading and unloading of the wheel pie 300 during feeding and discharging.

[0055] The movement of the moving part 6021 relative to the frame 601 and the lifting of the bearing part 6023 relative to the vertical rod 6022 can be driven by a servo motor, and the corresponding parameters can be adjusted according to the specifications of the wheel pie 300 to control the movement distance. The specific principle is not described in detail here.

[0056] In some embodiments, the locomotive wheel pie cleaning device further comprises a gantry manipulator (not shown in the figure) for clamping and placing the wheel pie 300 to be cleaned into the bearing part 6023 at the feeding area 101, and for clamping and removing the cleaned wheel pie 300 from the bearing part 6023 at the discharging area 105. In this way, the feeding and discharging of the translation trolley 600 are automatically completed by the gantry manipulator, further improving the automation level of the locomotive wheel pie cleaning device.

[0057] Exemplarily, the track of the gantry manipulator can be erected above the housing 100, and two grabbing manipulators are movably connected on the track. One of the grabbing manipulators is used to clamp and place the wheel pie 300 to be cleaned into the bearing part 6023 at the feeding area 101, and the other grabbing manipulator is used to clamp and remove the cleaned wheel pie 300 from the bearing part 6023 at the discharging area 105. The gantry manipulator and the rotary table conveying device 200 can be connected through Profinet communication.

[0058] As shown in Figure 2 , in some embodiments, the rotary table conveying device 200 further comprises a partition plate 3, which is radially outwardly arranged on the outer circumferential surface of the variable-position rotary table 1. There is one partition plate 3 between any two adjacent clamping joints 2, and the partition plate 3 is used to separate the wheel pies 300 on any two adjacent clamping joints 2. The partition plate 3 rotates synchronously with the variable-position rotary table 1.

[0059] The partition plate 3 can provide a physical barrier between the feeding area 101, the cleaning area 102, the rinsing area 103, the drying area 104 and the discharging area 105, so as to prevent cross contamination or mutual interference between adjacent processes.

[0060] As shown in Figure 1 , Figure 2 and Figure 6As shown, in some embodiments, the outer peripheral surface of the variable position turntable 1 is connected with an inner side nozzle 4, the inner side nozzle 4 is provided in one-to-one correspondence with the clamping joint 2, and the inner side nozzle 4 and the clamping joint 2 are configured to rotate together with the variable position turntable 1. The top plate 106 of the shell 100 is arranged on the top of the turntable type conveying device 200, and the top plate 106 is provided with a first connecting joint 10, a second connecting joint 20 and a third connecting joint 30. The first connecting joint 10 is arranged through the top plate 106 and can be connected and communicated with the inner side nozzle 4 rotating to the cleaning area 102, so as to spray cleaning liquid to the inner side surface of the wheel cake 300 in the cleaning area 102. The second connecting joint 20 is arranged through the top plate 106 and can be connected and communicated with the inner side nozzle 4 rotating to the rinsing area 103, so as to spray rinsing liquid to the inner side surface of the wheel cake 300 in the rinsing area 103. The third connecting joint 30 is arranged through the top plate 106 and can be connected and communicated with the inner side nozzle 4 rotating to the drying area 104, so as to spray drying gas to the inner side surface of the wheel cake 300 in the drying area 104.

[0061] The cleaning area 102 is provided with a first outer side nozzle 51 for spraying cleaning liquid to the outer side surface of the wheel cake 300 in the cleaning area 102. The rinsing area 103 is provided with a second outer side nozzle 52 for spraying rinsing liquid to the outer side surface of the wheel cake 300 in the rinsing area 103. The drying area 104 is provided with a third outer side nozzle 53 for spraying drying gas to the outer side surface of the wheel cake 300 in the drying area 104. Wherein, the inner side surface of the wheel cake 300 refers to the surface of the wheel cake 300 along the radial direction of the variable position turntable 1 towards the variable position turntable 1, and the outer side surface of the wheel cake 300 refers to the surface of the wheel cake 300 along the radial direction thereof.

[0062] That is, after a certain wheel cake 300 reaches the cleaning station of the cleaning area 102, the first connecting joint 10 is connected and communicated with the corresponding inner side nozzle 4, the cleaning liquid pump is started, the cleaning liquid flows to the inner side nozzle 4 through the first connecting joint 10 and is sprayed out of the inner side nozzle 4, and the cleaning liquid flows to the first outer side nozzle 51 at the same time and is sprayed out of the first outer side nozzle 51, so as to clean the inner and outer sides of the wheel cake 300. The actions of rinsing and drying are the same as cleaning, but the drying process sprays drying gas.

[0063] Through such a configuration, each process can simultaneously operate on the inner and outer sides of the wheel cake 300, which is beneficial to improve the cleaning efficiency and cleaning effect.

[0064] Wherein, the first connecting joint 10, the second connecting joint 20 and the third connecting joint 30 can be configured as a liftable structure, which is lowered when connection and communication is needed, and is raised when the variable position turntable 1 rotates. Exemplarily, the operation cycle of the first connecting joint 10, the second connecting joint 20 and the third connecting joint 30 is 3s.

[0065] In some embodiments, each card joint 2 is capable of rotating around its own axis and driving the corresponding wheel pie 300 to rotate together. In this way, the wheel pie 300 can rotate by 360° during cleaning, rinsing and drying, which helps to ensure that the cleaning liquid, rinsing liquid and drying gas can uniformly cover and fully clean every part of the wheel pie 300, avoiding the occurrence of cleaning blind spots.

[0066] As shown in Figure 1 and Figure 6 In some embodiments, the top plate 106 is further provided with a cleaning nozzle 6, which is arranged in the top plate 106 and is configured to spray cleaning liquid to the outer circumferential surface of the wheel pie 300 rotating to the cleaning area 102. In this way, the wheel pie 300 can be cleaned in all directions.

[0067] As shown in Figure 1 In some embodiments, the top plate 106 is provided with a condensation fog eliminator 7, which is configured to communicate with the cleaning area 102, the rinsing area 103 and the drying area 104.

[0068] Through such an arrangement, the condensation fog eliminator 7 can effectively reduce the mist generated by the evaporation of liquid in the cleaning area 102, the rinsing area 103 and the drying area 104, which helps to ensure the cleaning quality.

[0069] As shown in Figure 2 In some embodiments, the locomotive wheel pie cleaning device further comprises a cleaning liquid circulating device 400 and a rinsing liquid circulating device 500, which are arranged in the housing 100. The cleaning liquid circulating device 400 is used to provide clean cleaning liquid and recycle the used cleaning liquid, and the rinsing liquid circulating device 500 is used to provide clean rinsing liquid and recycle the used rinsing liquid.

[0070] The arrangement of the cleaning liquid circulating device 400 and the rinsing liquid circulating device 500 realizes the recycling of the cleaning liquid and the rinsing liquid, effectively reduces the liquid consumption in the cleaning operation, reduces resource waste, and thus significantly reduces the operating cost of the device.

[0071] Specifically, the used cleaning liquid is first filtered by a paper belt after being recycled, then enters a dirty liquid tank, and then is filtered by a filter pump + cloth bag fine filter for the second time before entering a clean liquid tank. The liquid used for cleaning is all taken from the clean liquid tank. The coarse filtration of the used rinsing liquid uses a filter basket, and the secondary filtration uses a cloth bag filter connected in series after a rinsing pump.

[0072] Optionally, the cleaning liquid is a mixture of water and detergent, the rinsing liquid is water, and the drying gas is compressed air. Further, the cleaning liquid can be equipped with a high-pressure pump for high-pressure and low-flow spraying cleaning, and low-pressure and high-flow rinsing. The cleaning liquid, rinsing liquid and drying gas can be equipped with an electric heating element (including temperature detection) to heat to the appropriate temperature. For example, the cleaning liquid is set to 55°C, the rinsing liquid is set to 45°C, and the drying gas is set to 30°C, so that the cleaning effect of the cleaning and rinsing process is better, and the water vapor can be evaporated faster during drying under the residual heat of the wheel cake 300, to achieve the drying and cooling effect.

[0073] Further, each liquid tank is equipped with a liquid level gauge and an automatic water replenishment mechanism. The upper and lower liquid levels can be detected as needed through the liquid level gauge. The automatic water replenishment mechanism can automatically replenish water when the liquid level is low and stop replenishing water when the liquid level is high. The amount of water replenishment is measured by a digital flow meter.

[0074] Still further, a detergent storage tank and a metering pump are provided to automatically supplement the appropriate amount of detergent according to the amount of water replenishment at a set concentration ratio to ensure the concentration of the cleaning liquid. The detergent storage tank can be provided with a low liquid alarm.

[0075] Optionally, a turbidity detector is provided in each clean liquid tank.
