Description

Technical Field

[0001] This utility model relates to the technical field of crankshaft cleaning equipment, and specifically discloses a crankshaft cleaning device. Background Technology

[0002] The crankshaft is one of the most important components of an engine. It bears the force transmitted from the connecting rod and converts it into torque, which is then output through the crankshaft to drive other accessories on the engine. The crankshaft is subjected to the combined effects of centrifugal force from the rotating mass, periodically changing gas inertial force, and reciprocating inertial force, which subject the crankshaft to bending and torsional loads. Therefore, the crankshaft is required to have sufficient strength and rigidity. During the machining and use of the crankshaft, a crankshaft cleaning device is needed to clean the crankshaft to remove impurities and stains adhering to the crankshaft surface.

[0003] Chinese Patent CN206951634U discloses an engine crankshaft cleaning device, including a support with a cleaning tank on the support. The cleaning tank contains four cleaning components, each including a bracket fixedly mounted within the cleaning tank and rotating wheels rotatably mounted on the bracket at the same horizontal line. The four rotating wheels on the cleaning components form a support space for the engine crankshaft. A brush holder is positioned between two brackets on the same side, and the brush holder is equipped with brushes for cleaning the crankshaft. This engine crankshaft cleaning device has a simple structure, is easy to operate, and can rotate and thoroughly clean the crankshaft. However, it lacks crankshaft draining and drying functions during use, requiring additional draining and drying equipment after cleaning, which is detrimental to saving on crankshaft cleaning equipment costs. Furthermore, during crankshaft transfer, residual water drips onto the ground, hindering the cleanliness of the crankshaft cleaning environment. Therefore, to solve these problems, this invention proposes a crankshaft cleaning device. Utility Model Content

[0004] The present invention aims to provide a crankshaft cleaning device that combines crankshaft cleaning, draining and drying functions, enriching the usage of the cleaning device, preventing residual water on the crankshaft from dripping onto the ground outside the cleaning device, and helping to maintain the cleanliness of the crankshaft cleaning working environment.

[0005] This utility model is achieved through the following technical solution:

[0006] A crankshaft cleaning device includes a cleaning and drying mechanism and a lifting mechanism. The cleaning and drying mechanism has lifting mechanisms at both ends and a support mechanism on its inner side. The cleaning and drying mechanism includes an ultrasonic cleaning chamber with support plates on both sides. A first telescopic rod is connected to the side of each support plate that is far from each other. Two hot air blowers are symmetrically arranged at both ends of the ultrasonic cleaning chamber. Two top covers are symmetrically arranged on the top of the ultrasonic cleaning chamber. The lifting mechanism includes a second telescopic rod and a connecting plate. The telescopic end of the second telescopic rod is connected to the connecting plate, and a hanging rod is provided at the end of the connecting plate that is far from the second telescopic rod. The support mechanism includes a mesh plate and U-shaped limiting blocks. Multiple U-shaped limiting blocks are symmetrically arranged on both sides of the top of the mesh plate. Two limiting plates are symmetrically connected to both ends of the mesh plate, and lifting lugs are connected to both ends of the top of the mesh plate.

[0007] As a further feature of the above solution, the ultrasonic cleaning box has through holes on both sides, and a first limiting groove is provided at both ends of the through holes. The support plate passes through the interior of the through holes and is slidably connected to the through holes. A first protrusion is provided at both ends of the support plate, and the first protrusion is slidably connected to the first limiting groove to restrict the movement direction of the support plate and provide stable support for the support plate. The support plate is detachably connected to the first telescopic rod, and the position of the support plate can be adjusted by extending and retracting the first telescopic rod so that after the crankshaft is cleaned, the support mechanism can be supported from below the mesh plate to facilitate drainage and drying. A first bracket is connected to the outside of the first telescopic rod, and the first bracket is connected to the ultrasonic cleaning box to provide support for the first telescopic rod, facilitating the installation and maintenance of the first telescopic rod, the support plate, and the first bracket.

[0008] As a further feature of the above-mentioned solution, a water inlet pipe is connected to the upper side of one side of the ultrasonic cleaning box for easy water filling. A drain pipe is provided on the lower side of one side of the ultrasonic cleaning box, and a valve is provided at one end of the drain pipe to facilitate the discharge of wastewater from the ultrasonic cleaning box. Two air inlet pipes are symmetrically arranged at both ends inside the ultrasonic cleaning box. The end of each air inlet pipe away from the ultrasonic cleaning box can be detachably connected to a cap to prevent water from the ultrasonic cleaning box from splashing into the air inlet pipe during crankshaft cleaning. The air outlet of the hot air blower is connected to the inside of the air inlet pipe, which allows the hot air blower to inject high-temperature airflow into the ultrasonic cleaning box through the air inlet pipe to dry the crankshaft.

[0009] As a further feature of the above solution, two slots are symmetrically arranged on the upper sides of the ultrasonic cleaning chamber, and two insertion rods are provided at the lower ends of the top cover. The insertion rods are inserted into the slots, which can cover the top of the ultrasonic cleaning chamber during the crankshaft drying process, reducing heat loss in the ultrasonic cleaning chamber and ensuring the drying effect of the crankshaft. Two handles are symmetrically connected to the top of the top cover for easy gripping by workers when taking off and putting on the top cover. Two second limiting grooves are symmetrically arranged on the inner walls of both ends of the ultrasonic cleaning chamber. The second limiting grooves are slidably connected to the limiting plate, which can restrict the movement direction of the supporting mechanism.

[0010] As a further provision of the above solution, a second bracket is provided on the outer side of the second telescopic rod, the lower end of the second telescopic rod is connected to the second bracket, and the second bracket is connected to the ultrasonic cleaning box, which facilitates the installation and maintenance of the above components. Limiting holes are provided on both sides of the second bracket, and second protrusions are provided on both sides of the connecting plate. The second protrusions pass through the interior of the limiting holes and are slidably connected to the limiting holes, which can restrict the movement direction of the connecting plate and its connecting components.

[0011] As a further feature of the above solution, a connecting seat is provided below the end of the connecting plate near the boom. The upper end of the boom is rotatably connected to the connecting seat, which facilitates the adjustment of the angle of the boom and the hook connected below it, and provides convenience for the connection between the hook and the lifting lug. A hook is provided below the boom, and the hook is connected to the lifting lug, which facilitates the lifting mechanism to pull the support mechanism and crankshaft out of the liquid in the ultrasonic cleaning tank, saving workers the effort of manually lifting the support mechanism and crankshaft.

[0012] As a further feature of the above solution, multiple mounting holes arranged in a linear array are provided on both sides of the mesh plate. The lower end of the U-shaped limiting block is detachably connected to the mounting holes, which helps to adjust the installation position of the U-shaped limiting block according to the length of the crankshaft. The inner side of the U-shaped limiting block is provided with a U-shaped limiting groove, which allows the two ends of the crankshaft to be placed in two oppositely arranged U-shaped limiting grooves to restrict the position of the crankshaft. To prevent the crankshaft from stacking during cleaning, draining, and drying, two support legs are detachably connected to the lower ends of the mesh plate, which can separate the mesh plate from the bottom of the ultrasonic cleaning box to ensure the cleaning effect under the crankshaft.

[0013] As a further feature of the above solution, a controller is provided on one side of the ultrasonic cleaning box to facilitate the control of the operation of relevant components in the device.

[0014] The present invention has the following beneficial effects during use:

[0015] The combined use of two support plates and a first telescopic rod in the cleaning and drying mechanism allows the support plates to be pushed from the outside to the inside of the ultrasonic cleaning chamber after the crankshaft cleaning is completed. This is done by extending the first telescopic rod to support the mesh plate and its connecting components from both sides below the mesh plate, which helps to separate the crankshaft from the cleaning fluid and facilitates drainage of the support mechanism and crankshaft. The combination of the hot air blower, air inlet pipe, and cover allows the cover to be used to seal the air inlet pipe during the crankshaft cleaning process to prevent liquid from splashing into the air inlet pipe and affecting the normal operation of the hot air blower. After cleaning is completed and the liquid in the ultrasonic cleaning chamber is drained, the hot air blower is started to blow high-temperature air into the ultrasonic cleaning chamber to dry the support mechanism and crankshaft. This enriches the function of the cleaning device and expands its applicability.

[0016] The combination of the second telescopic rod, connecting plate, hanging rod and hook in the lifting mechanism can pull the support mechanism together with the crankshaft out of the liquid in the ultrasonic cleaning box after the crankshaft is cleaned, so that the crankshaft is separated from the liquid and the workload of workers to manually retrieve the support mechanism and crankshaft.

[0017] The design of multiple mounting holes in the support mechanism allows the installation position of the U-shaped limiting blocks to be adjusted according to the length of the crankshaft to be cleaned. This ensures that both ends of the crankshaft are placed in the U-shaped limiting grooves inside the two U-shaped limiting blocks that are set opposite each other, preventing the crankshaft from stacking during cleaning, draining, and drying, thus ensuring the quality of crankshaft cleaning and improving the efficiency of crankshaft cleaning.

[0028] like Figure 1 and Figure 2 As shown, the ultrasonic cleaning box 11 has through holes 111 on both sides, and a first limiting groove 1111 is provided at both ends of the through holes 111. The support plate 13 passes through the interior of the through holes 111 and is slidably connected to the through holes 111. A first protrusion 131 is provided at both ends of the support plate 13. The first protrusion 131 is slidably connected to the first limiting groove 1111 to restrict the movement direction of the support plate 13 and provide stable support for the support plate 13. The support plate 13 is detachably connected to the first telescopic rod 14, and the position of the support plate 13 can be adjusted by the extension and retraction of the first telescopic rod 14 so that after the crankshaft is cleaned, it can support the support mechanism 3 from below the mesh plate 31, which facilitates drainage and drying. A first bracket 141 is connected to the outside of the first telescopic rod 14. The first bracket 141 is connected to the ultrasonic cleaning box 11 and can provide support for the first telescopic rod 14, which facilitates the installation and maintenance of the first telescopic rod 14, the support plate 13 and the first bracket 141.

[0029] like Figure 1 and Figure 2 As shown, a water inlet pipe 112 is connected to the upper side of one side of the ultrasonic cleaning chamber 11 for easy water filling. A drain pipe 113 is provided on the lower side of one side of the ultrasonic cleaning chamber 11, and a valve 114 is provided at one end of the drain pipe 113 to facilitate the discharge of sewage from the ultrasonic cleaning chamber 11. Two air inlet pipes 116 are symmetrically arranged at both ends inside the ultrasonic cleaning chamber 11. The end of the air inlet pipe 116 away from the ultrasonic cleaning chamber 11 can be detachably connected to a cover 117 to prevent water from splashing into the air inlet pipe during crankshaft cleaning. The air outlet of the hot air blower 12 is connected to the inside of the air inlet pipe 116, which allows the hot air blower 12 to inject high-temperature airflow into the ultrasonic cleaning chamber 11 through the air inlet pipe 116 to dry the crankshaft.

[0030] like Figure 1 and Figure 3 As shown, two slots 115 are symmetrically arranged on the upper sides of the ultrasonic cleaning chamber 11. Insert rods 151 are provided at both ends of the lower part of the top cover 15. The insert rods 151 are inserted into the slots 115, allowing the ultrasonic cleaning chamber 11 to be covered during crankshaft drying, reducing heat loss and ensuring the drying effect of the crankshaft. Two handles 152 are symmetrically connected to the top of the top cover 15 for easy gripping by workers when taking it up or down. Two second limiting grooves 118 are symmetrically arranged on the inner walls of both ends of the ultrasonic cleaning chamber 11. The second limiting grooves 118 are slidably connected to the limiting plate 33, restricting the movement direction of the supporting mechanism 3.

[0031] like Figure 1 and Figure 4 As shown, a second bracket 21 is provided on the outer side of the second telescopic rod 22. The lower end of the second telescopic rod 22 is connected to the second bracket 21. The second bracket 21 is connected to the ultrasonic cleaning box 11, which facilitates the installation and maintenance of the above components. Limiting holes 211 are provided on both sides of the second bracket 21. Second protrusions 231 are provided on both sides of the connecting plate 23. The second protrusions 231 pass through the interior of the limiting holes 211 and are slidably connected with the limiting holes 211, which can limit the movement direction of the connecting plate 23 and its connecting components.

[0032] like Figure 1 and Figure 4 As shown, a connecting seat 232 is provided below one end of the connecting plate 23 near the lifting rod 24. The upper end of the lifting rod 24 is rotatably connected to the connecting seat 232, which facilitates the adjustment of the angle of the lifting rod 24 and the hook 25 connected below it, and provides convenience for the connection between the hook 25 and the lifting lug 35.

[0033] like Figure 1 and Figure 5 As shown, the mesh plate 31 has multiple mounting holes 311 arranged in a linear array on both sides. The lower end of the U-shaped limiting block 32 is detachably connected to the mounting holes 311, which helps to adjust the installation position of the U-shaped limiting block 32 according to the length of the crankshaft. The inner side of the U-shaped limiting block 32 is provided with a U-shaped limiting groove 321, which allows the two ends of the crankshaft to be placed in two oppositely arranged U-shaped limiting grooves 321 to limit the position of the crankshaft. To prevent the crankshaft from stacking during cleaning, draining and drying, the bottom ends of the mesh plate 31 are detachably connected to two support legs 34, which can separate the mesh plate 31 from the bottom of the ultrasonic cleaning box 11 to ensure the cleaning effect under the crankshaft.

[0034] like Figure 1 As shown, a controller 4 is provided on one side of the ultrasonic cleaning box 11 to facilitate the control of the operation of the relevant components in the device.

[0035] The crankshaft cleaning device disclosed in this embodiment involves holding the handle 152 and pulling the two top covers 15 upwards in sequence to remove the insertion rod 151 from the slot 115. The two top covers 15 are then removed from the top of the ultrasonic cleaning chamber 11 and placed aside. Simultaneously, the controller 4 controls the extension of the two second telescopic rods 22, causing the connecting plate 23 and the hanging rod 24 to move upwards, pulling the supporting mechanism 3 upwards from the bottom of the ultrasonic cleaning chamber 11. This causes the limiting plate 33 to slide upwards a certain distance in the second limiting groove 118. Simultaneously, the controller 4 controls the extension of the two first telescopic rods 14, pushing the support plate 13 through the through hole 111 from the outside of the ultrasonic cleaning chamber 11 to a certain depth below the inner mesh plate 31. The controller 4 then controls the retraction of the second telescopic rods 22, causing the supporting mechanism 3 to move towards the support plate 13. Once the two support plates 13 are respectively aligned with the mesh plate 31... When both sides are in contact, close the second telescopic rod 22. At this time, the two support plates 13 provide support for the support mechanism 3 from the lower sides of the mesh plate 31, releasing the tension on the hook 25. According to the length of the crankshaft to be cleaned, adjust the mounting holes 311 connected to the U-shaped limit blocks 32 on both sides above the mesh plate 31. After the adjustment is completed, place the two ends of the crankshaft to be cleaned in the U-shaped limit grooves 321 inside the U-shaped limit blocks 32 in turn. Use the controller 4 to control the extension of the two second telescopic rods 22, tighten the lifting rod 24 and the hook 25, and lift the support mechanism 3 together with the crankshaft upward until the mesh plate 31 is separated from the support plate 13. Use the controller 4 to control the retraction of the two first telescopic rods 14, and pull the support plate 13 out from the through hole 111 to the outside of the ultrasonic cleaning box 11, so that the side of the support plate 13 away from the first telescopic rod 14 blocks the through hole 111.

[0036] Control the retraction of the two second telescopic rods 22, causing the support mechanism 3 and crankshaft to move downwards along the direction of the second limiting groove 118 under the action of gravity until the lower end of the support leg 34 contacts the bottom of the ultrasonic cleaning box 11. Close the two second telescopic rods 22, connect the sewage pipe to the drain pipe 113, connect the original water injection pipe to the water inlet pipe 112, and inject sufficient clean water into the ultrasonic cleaning box 11. Use the controller 4 to start the ultrasonic cleaning box 11, causing the clean water to vibrate and clean the crankshaft. After the first cleaning is completed, open the valve 114 to discharge the sewage in the ultrasonic cleaning box 11 through the drain pipe 113 and the sewage discharge pipe. After draining, close the valve 114, inject clean water into the ultrasonic cleaning box 11 again, and start the ultrasonic cleaning box for a second cleaning. After the second cleaning is completed, drain the sewage in the ultrasonic cleaning box 11 again, and unscrew the four caps 117 from the four air inlet pipes 116 in sequence. Meanwhile, using controller 4, repeat the above-described operation of controlling the extension and retraction of the second telescopic rod 22 and the first telescopic rod 14 to lift the support mechanism 3 and the crankshaft upwards, so that the support plate 13 provides support for the support mechanism 3 and the crankshaft from below the mesh plate 31, so that the water remaining on the crankshaft drips from the mesh of the mesh plate 31 to the bottom of the ultrasonic cleaning box 11 and is discharged through the drain pipe 113. Reset the two top covers 15, restore the connection between the insertion rod 151 and the slot 115, and use controller 4 to simultaneously start the four hot air blowers 12, so that the hot air blowers 12 inject high-temperature airflow into the ultrasonic cleaning box 11 through the air inlet pipe 116 to dry the crankshaft. The water vapor generated during drying moves upward and is discharged through the gap between the two top covers 15 until the crankshaft is dried. Remove the top cover 15, remove the crankshaft from the support mechanism 3, and place the crankshaft to be cleaned on the support mechanism 3. Repeat the above operation to continue the crankshaft cleaning operation.

[0037] The crankshaft cleaning device disclosed in this utility model includes a controller 4, an ultrasonic cleaning box 11, a water inlet pipe 112, a drain pipe 113, a valve 114, an air inlet pipe 116, a cover 117, a hot air blower 12, a first telescopic rod 14, a first bracket 141, a top cover 15, an insertion rod 151, a handle 152, a second telescopic rod 22, a connecting seat 232, a hanging rod 24, a hook 25, a mesh plate 31, a support leg 34, and a lifting lug 35.
