[0002] At present, the cleaning of motorcycle frames mostly relies on traditional manual cleaning or simple mechanical cleaning, which is inefficient and difficult to ensure the cleaning quality. With the continuous expansion of the motorcycle market, the efficiency and quality requirements for frame cleaning are also constantly increasing, and there is an urgent need for a device that can efficiently and automatically clean motorcycle frames.

[0003] The traditional frame cleaning method usually adopts a single-point cleaning method, which requires cleaning a frame separately, then removing the cleaned frame and replacing it with a new frame for the next round of cleaning. This cleaning method is not only inefficient, but also has uneven cleaning effects and requires more manual intervention. Therefore, further improvements can be made. Summary of the invention

[0005] In the first aspect, the present application provides a frame cleaning device, which adopts the following technical solution: A frame cleaning device comprises a hanging chain conveyor line, a slide seat of the hanging chain conveyor line is installed with a hanger for hanging the frame; the hanging chain conveyor line comprises a processing section and a return section, both ends of the processing section are respectively provided with a loading point and a unloading point, the processing section is sequentially provided with a spray chamber, a cleaning chamber and a drying chamber from the loading point to the unloading point, and the spray chamber, the cleaning chamber and the drying chamber are respectively used for spraying detergent treatment, water spray cleaning treatment and drying treatment on the suspended and conveyed frame.

[0006] By adopting the above technical solution, in the actual working process, the worker hangs the frame on the hanger in the hanging chain conveyor line from the loading point in the processing section, so that the frame passes through the spray room, the cleaning room and the drying room in sequence with the hanger to spray detergent, spray water and dry the frame to complete the cleaning work of the frame, and after the cleaning is completed, the unloading point in the processing section is unloaded, so that the empty hanger can return to the loading point along the return section for the next round of work. This assembly line automatic cleaning method is not only highly efficient, but also has a better cleaning effect and does not require much manual intervention.

[0007] Optionally, a mount is fixedly mounted on the slide, a gear is rotatably mounted on the mount, and the bracket is fixedly mounted on the bottom of the gear; a first rack is installed in the spray chamber, the first rack is arranged parallel to the segment of the processing section in the spray chamber, and when the frame passes through the first rack with the bracket, the gear on the mount is meshed along the first rack.

[0008] By adopting the above technical solution, when the frame passes through the spray chamber with the hanger to be sprayed with detergent, the gear on the hanger is meshed with the first rack in the spray chamber, so that the frame rotates synchronously along the first rack, that is, it rotates while conveying, so that the spray chamber can perform a more comprehensive detergent spraying treatment on the entire body of the frame.

[0009] Optionally, a second rack is installed in the cleaning chamber, and the second rack is arranged parallel to the segment of the processing section in the cleaning chamber, and when the frame passes through the second rack with the hanging bracket, the gear on the hanging bracket engages along the second rack.

[0010] By adopting the above technical solution, when the frame passes through the cleaning chamber with the hanging rack for water spray cleaning, the gear on the hanging bracket meshes with the second rack in the cleaning chamber, so that the frame rotates synchronously along the second rack, that is, it rotates while being transported, so that the cleaning chamber can perform more comprehensive water spray cleaning on the whole body of the frame to further improve the cleaning effect.

[0011] Optionally, the hanging seat includes a hanging rod and a rod sleeve, the hanging rod is vertically arranged and slidably installed in the rod sleeve, and the upper and lower ends of the hanging rod extend out of the rod sleeve; a damping spring is installed in the rod sleeve, and the damping spring sleeve is installed on the hanging rod and is used to damp the up and down movement of the hanging rod; the gear is rotatably installed on the bottom end of the hanging rod, and the rod sleeve is fixedly installed on a sliding seat in the hanging chain conveyor line; the section between the washing chamber and the drying chamber in the processing section is a spin-drying section, and a wave channel is installed at the position of the spin-drying section, the bottom surface of the wave channel is a wave surface, and the wave channel is arranged parallel to the spin-drying section; a rolling member is installed on the top of the hanging rod, and when the frame passes through the wave channel with the hanging bracket, the hanging rod abuts against the wave channel through the rolling member.

[0012] By adopting the above technical solution, when the frame passes through the wave channel in the spin-drying section with the hanging rack, the hanging rod in the hanging seat abuts against the wave channel through the rolling element. Due to the action of the wave surface of the bottom surface of the wave channel, the hanging rod is transmitted along the wave channel in an undulating manner, so as to drive the frame to perform synchronous undulating motion during the transmission process, so as to further accelerate the spinning of the clean water reserved on the surface of the frame after cleaning, and then perform an undulating spin-drying treatment, so that after entering the drying room later, it can be dried faster.

[0014] By adopting the above technical solution, when the frame is transported along with the hanger and enters the wave channel position, the hanger rod is gradually compressed downward using the introduction section to give the damping spring an initial preload force, so as to subsequently drive the frame to be transported along the wave channel in an undulating manner.

[0015] Optionally, the rolling element is a roller.

[0016] Optionally, the hanger includes a frame body and a hook installed on the frame body, and the hook is in an inward buckle shape.

[0017] By adopting the above technical solution, the workers can load or unload the frame at the loading point or unloading point by using the hook. At the same time, the inward buckle suspension method makes it difficult for the frame to fall off during the transmission process.

At the loading point, hang the frame on the bracket on the hanging chain conveyor line; S2, the frame passes through the spraying room, the cleaning room, the drying section and the drying room in sequence with the hanging rack to be sprayed with detergent, washed with water, dried by jumping and dried to complete the cleaning of the frame; S3, after cleaning is completed, unloading is performed at the unloading point in the processing section; S4, the empty rack returns to the loading point along the return section to carry out the next round of work.

[0019] Optionally, in step S2: while the frame is passing through the spray chamber for spraying detergent along with the hanger, the frame uses the gear on the hanger to mesh with the first rack in the spray chamber to achieve rotation while conveying for rotary spraying detergent; similarly, while the frame is passing through the cleaning chamber for spraying water along with the hanger, the frame uses the gear on the hanger to mesh with the second rack in the cleaning chamber to achieve rotation while conveying for rotary spraying water for cleaning.

[0020] By adopting the above technical solution, when the frame passes through the spraying chamber with the hanging rack to be sprayed with detergent, the frame is conveyed and rotated at the same time, so that the spraying chamber can perform a more comprehensive detergent spraying treatment on the entire body of the frame. Similarly, when the frame passes through the washing chamber with the hanging rack to be sprayed with water for washing, the frame is conveyed and rotated at the same time, so that the washing chamber can perform a more comprehensive water spraying and washing treatment on the entire body of the frame, so as to further improve the washing effect.

[0021] Optionally, in step S2: when the frame passes through the wavy channel in the spin-drying section with the hanging rack, the frame uses the rolling parts on the top of the hanging rod to perform undulating transmission along the wavy surface of the bottom of the wavy channel, so as to perform undulating transmission and spinning at the same time, thereby performing the spin-drying process.

[0029] The present application is further described in detail below in conjunction with the accompanying drawings 1-4.

[0030] The embodiment of the present application discloses a vehicle frame cleaning device.

[0031] Reference Figure 1A frame cleaning device includes a suspension chain conveyor line 1 and a spray chamber 2, a cleaning chamber 3 and a drying chamber 4 arranged on the conveying path of the suspension chain conveyor line 1; wherein the suspension chain conveyor line 1 is arranged horizontally, and the sliding seat of the suspension chain conveyor line 1 is installed with a hanger 5 for hanging the frame. The suspension chain conveyor line 1 includes a processing section 11 and a return section 12, and a loading point 13 and a unloading point 14 are respectively arranged at both ends of the processing section 11, so that workers can load or unload the frame here. The spray chamber 2, the cleaning chamber 3 and the drying chamber 4 are arranged in sequence between the loading point 13 and the unloading point 14 in the processing section 11, and the processing section 11 is sequentially arranged in the spray chamber 2, the cleaning chamber 3 and the drying chamber 4 for conveying, so as to spray the cleaning agent, spray water and dry the frame during the conveying process to complete the cleaning work of the frame. This assembly line type automatic cleaning method is not only highly efficient, but also has a better cleaning effect, and does not require much manual intervention.

[0032] Reference Figure 1 and Figure 2 In this embodiment, a hanger 6 is fixedly mounted on the slide, a gear 7 is rotatably mounted on the hanger 6, and the gear 7 is arranged horizontally, and a hanger 5 is fixedly mounted at the bottom of the gear 7, so that the hanger 5 can rotate with the gear 7. Correspondingly, a first rack 8 is installed in the spray chamber 2, and the first rack 8 is arranged horizontally, and the first rack 8 is arranged parallel to the segment of the processing section 11 in the spray chamber 2, and when the frame passes through the first rack 8 with the hanger 5, the gear 7 on the hanger 6 is meshed along the first rack 8, so that the frame rotates synchronously along the first rack 8, that is, it rotates while conveying, so that the spray chamber 2 can perform a more comprehensive detergent spraying treatment on the frame.

[0033] Reference Figure 1 and Figure 2 Similarly, in this embodiment, a second rack 9 is installed in the cleaning chamber 3, the second rack 9 is horizontally arranged, and the second rack 9 is arranged parallel to the segment of the processing section 11 in the cleaning chamber 3, and when the frame passes through the second rack 9 with the hanging rack 5, the gear 7 on the hanging seat 6 is engaged along the second rack 9, so that the frame rotates synchronously along the second rack 9, that is, it rotates while conveying, so that the cleaning chamber 3 can perform a more comprehensive water spray cleaning treatment on the whole body of the frame to further improve the cleaning effect.

[0034] Reference Figure 3Specifically, in this embodiment, the hanging seat 6 includes a hanging rod 61 and a rod sleeve 62. The hanging rod 61 is vertically arranged and slidably installed in the rod sleeve 62, and the upper and lower ends of the hanging rod 61 extend out of the rod sleeve 62. A damping spring 63 is installed in the rod sleeve 62 to damp and limit the up and down movement of the hanging rod 61. The gear 7 is rotatably installed at the bottom end of the hanging rod 61, and the rod sleeve 62 is fixedly installed on the slide seat in the hanging chain conveyor line 1 through a bracket.

[0035] Reference Figure 1 and Figure 3 The section between the washing chamber 3 and the drying chamber 4 in the processing section 11 is the drying section 10, and a wave channel 101 is installed at the drying section 10. The bottom surface of the wave channel 101 is a wave surface, and the wave channel 101 is arranged parallel to the drying section 10. Correspondingly, a rolling member 64 is installed at the top of the hanging rod 61, and when the frame passes through the wave channel 101 with the hanging rack 5, the hanging rod 61 abuts against the wave channel 101 through the rolling member 64.

[0036] Therefore, when the frame passes through the wavy channel 101 in the spin-drying section 10 with the hanging rack 5, the hanging rod 61 in the hanging seat 6 abuts against the wavy channel 101 through the rolling member 64. Due to the action of the wavy surface of the bottom surface of the wavy channel 101, the hanging rod 61 is transmitted along the wavy channel 101 in an undulating manner, so as to drive the frame to perform synchronous undulating motion during the transmission process, so as to further accelerate the spinning of the clean water reserved on the surface of the frame after cleaning, and then perform an undulating spin-drying treatment, so that after entering the drying chamber 4 later, it can be dried faster.

[0037] Reference Figure 3 Specifically, in this embodiment, the hanging rod 61 limits its up and down movement by means of a limiting flange 65. Among them, a travel slot 66 is extended in the rod sleeve 62 along its length direction, and the limiting flange 65 is fixedly installed on the outer wall of the hanging rod 61, and the limiting flange 65 is slidably set in the travel slot 66 to limit the up and down sliding of the hanging rod 61. Correspondingly, the damping spring 63 is sleeved and installed on the hanging rod 61, and the bottom support of the damping spring 63 is connected to the bottom surface of the travel slot 66, and the top of the damping spring 63 is connected to the limiting flange 65 in the hanging rod 61 to support the hanging rod 61.

[0038] In this embodiment, the rolling element 64 is a roller. In other embodiments, the rolling element 64 may be a rolling element such as a ball.

[0039] Reference Figure 4In this embodiment, an introduction section 102 is formed at the input end of the wave channel 101, and the introduction section 102 is spliced ​​to the wave channel 101 in a circular arc transition from top to bottom. When the frame is transported along with the hanger 6 and enters the position of the wave channel 101, the hanger rod 61 is gradually compressed downward by the introduction section 102 to give the damping spring 63 an initial preload force, so as to drive the frame to be transported along the wave channel 101 in an undulating manner.

[0040] Specifically, in this embodiment, the hanger 5 includes a frame body 51 and a hook 52 mounted on the frame body 51, and the hook 52 is in an inward buckle shape. Preferably, in this embodiment, the number of the hooks 52 is two. By using the hooks 52, workers can load or unload the frame at the loading point 13 and the unloading point 14. At the same time, this inward buckle hanging method makes it difficult for the frame to fall off during the transmission process.

[0041] The implementation principle of a frame cleaning device in this application is: In the actual working process, the worker hangs the frame on the hanger 5 in the hanging chain conveyor line 1 from the loading point 13 in the processing section 11, so that the frame passes through the spray room 2, the cleaning room 3 and the drying room 4 in sequence with the hanger 5 to be sprayed with detergent, sprayed with water and dried to complete the cleaning work of the frame. After the cleaning is completed, the unloading is carried out at the unloading point 14 in the processing section 11, so that the empty hanger 5 can return to the loading point 13 along the return section 12 for the next round of work.

[0042] At the same time, when passing through the spray chamber 2, the frame is driven to rotate synchronously by means of the meshing cooperation between the gear 7 in the mount 6 and the first rack 8 in the spray chamber 2, that is, it rotates while transmitting, so that the spray chamber 2 can perform a more comprehensive cleaning agent spraying treatment on the entire body of the frame.

[0043] Similarly, when cleaning chamber 3, the frame is driven to rotate synchronously by means of the meshing cooperation between the gear 7 in the mounting 6 and the second rack 9 in the cleaning chamber 3, that is, it rotates while transmitting, so that the cleaning chamber 3 can perform a more comprehensive water spray cleaning treatment on the whole body of the frame to further improve the cleaning effect.

[0044] In addition, when the frame is being conveyed from the spray chamber 2 to the cleaning chamber 3, the wave channel 101 in the spin-drying section 10 is utilized to make the hanging rod 61 be conveyed in an undulating manner along the wave channel 101, so as to drive the frame to perform synchronous undulating motion during the transmission process, so as to further accelerate the spinning of the clean water reserved on the surface of the frame after cleaning, and then perform an undulating spin-drying treatment, so that after entering the drying chamber 4 later, it can be dried faster.

[0045] The embodiment of the present application also discloses a vehicle frame cleaning method.

[0046] A frame cleaning method, using the frame cleaning device described above, comprises the following steps: S1, at the loading point 13, the frame is suspended and installed on the hanger 5 on the hanging chain conveyor line 1; S2, the frame passes through the spray chamber 2, the cleaning chamber 3, the spin-drying section 10 and the drying chamber 4 in sequence with the hanging rack 5, so as to be sprayed with detergent, washed with water, subjected to a jumping spin-drying treatment and dried, so as to complete the cleaning of the frame; S3, after the cleaning is completed, the material is unloaded at the unloading point 14 in the processing section 11; S4, the empty rack 5 returns to the loading point 13 along the return section 12 to carry out the next round of work.

[0047] Wherein, in step S2: When the vehicle frame passes through the spray chamber 2 with the hanger 5 for spraying with the detergent, the gear 7 on the hanger 6 of the vehicle frame is meshed with the first rack 8 in the spray chamber 2 to realize rotation while conveying, so as to perform a rotary spraying of the detergent, so that the spray chamber 2 can perform a more comprehensive detergent spraying treatment on the whole body of the vehicle frame.

[0048] Similarly, when the frame passes through the cleaning chamber 3 with the hanger 5 for water spray cleaning, the frame uses the gear 7 on the hanger 6 to mesh with the second rack 9 in the cleaning chamber 3 to achieve rotation while conveying to perform rotary water spray cleaning, so that the cleaning chamber 3 can perform more comprehensive water spray cleaning on the entire body of the frame to further improve the cleaning effect.

[0049] While the frame passes through the wavy channel 101 in the spin-drying section 10 along with the hanging rack 5, the frame uses the rolling member 64 on the top of the hanging rod 61 to perform an undulating conveyance along the wavy surface of the bottom of the wavy channel 101, so as to perform an undulating and swinging process while conveying, so that after entering the drying chamber 4, the drying process can be performed faster.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
