At the same time, the loading carrier plate or the unloading carrier plate falls to the ground, and the staff places the plastic steel pipe support component with the square steel pipe on the loading carrier plate. Similarly, after the loading cylinder moves down to the bottom, the corresponding plastic steel pipe support component on the loading carrier plate is pushed to move to the carrier plate, and the new square steel pipe is cleaned and replaced, and the washed square steel pipe is removed at the same time. The loading and unloading quantity and the cleaning quantity are large each time, so as to improve the cleaning effect. Moreover, the staff only needs to directly insert each square steel pipe into the outer side of the elastic limiting component before loading the square steel pipe as a whole. The loading operation of the square steel pipe is simple and convenient.

Description

Technical Field

[0001] The invention relates to the technical field of cleaning equipment, and in particular to a synchronous integrated cleaning device for inside and outside of a plastic-steel profile. Background Art

[0002] The existing plastic steel pipe cleaning uses a soft brush to gently brush away the dust and debris on the surface of the plastic steel pipe. For some stubborn stains, apply an appropriate amount of detergent on the rag and then wipe the stains, but be careful that the detergent cannot be highly corrosive to avoid damaging the plastic steel pipe. Then, rinse the plastic steel pipe with clean water to ensure that the detergent and stains are thoroughly rinsed off. After cleaning, dry the pipe body in time to avoid rust or bacterial growth caused by residual moisture. Regular cleaning of plastic steel pipes can maintain their good performance and appearance and extend their service life. Whether it is used in water supply pipes or other fields, plastic steel pipes can better play their role.

[0003] The authorization announcement number CN214976407U discloses an automatic impurity removal and blowing device for the inner wall of a steel pipe used in the production of plastic-coated steel pipes. By utilizing a pulley transmission, the rotating rod and the spiral rod can rotate synchronously, the adjusting disk can rotate, and the two cleaning rods can clean the inside of the steel pipe. By setting a rotating rod that passes through the left and right sides, the water inside the water storage chamber can be transferred to the inside of the water outlet pipe through the rotating rod, and then the inside of the steel pipe is blown and washed through the water outlet hole. The impurities in the water are separated by the filter net inside the collecting box, and the filtered water enters the water storage chamber through the drain hole for recycling.

[0004] However, there are the following problems in the above prior art:

[0005] 1. It is necessary to manually insert a plastic steel pipe horizontally into the outside of the cleaning rod, and the other end needs to be inserted into the outside of the water pipe before the cleaning operation can be performed. Not only is the manual installation of the plastic steel pipe troublesome, but the number of cleanings is single, resulting in a low cleaning efficiency of the entire plastic steel pipe;

[0006] 2. It can only clean the inside of the plastic steel pipe, but cannot clean the outside of the plastic steel pipe at the same time. The outside of the plastic steel pipe needs to be cleaned separately, which also leads to low cleaning efficiency.

[0007] Therefore, a synchronous integrated cleaning device for the inside and outside of plastic-steel profiles is needed. Summary of the invention

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figure 1-Figure 5 As shown, a synchronous integrated cleaning device for plastic steel profile inside and outside comprises a supporting chassis 1 and an air intake pipe 2 and a water intake pipe 3 installed at the upper end of the supporting chassis 1. The air intake pipe 2 is externally connected to a total air pump, and the water intake pipe 3 is externally connected to a total clean water pump. The output end of the air intake pipe 2 is located inside the supporting chassis 1 and is provided with a plurality of them. The output end of the water intake pipe 3 is located inside the supporting chassis 1 and is also provided with a plurality of them. The output ends of the air intake pipe 2 and the water intake pipe 3 are both connected to an external cleaning component 4 and an internal cleaning component 5 installed inside the supporting chassis 1. The external cleaning component 4 is located outside the internal cleaning component 5. A feeding cylinder 6 is provided at the lower sides of the external cleaning component 4 and the internal cleaning component 5. A bearing cylinder is installed at the upper end of the feeding cylinder 6. Plate 61, a plastic steel pipe support assembly 7 is placed on the upper end of the carrying plate 61, a loading carrying plate 62 is slidably arranged on the supporting chassis 1 on one side of the carrying plate 61, and a unloading carrying plate 63 is slidably arranged on the supporting chassis 1 on the other side of the carrying plate 61, rollers 11 are arranged at the four inner corners of the supporting chassis 1, and a transmission belt 12 is sleeved on the outer side of the roller 11, one end of the transmission belt 12 close to the loading carrying plate 62 is fixedly connected to one end of the carrying plate 61, and the other end of the transmission belt 12 is fixedly connected to the loading carrying plate 62, one end of the transmission belt 12 close to the unloading carrying plate 63 is fixedly connected to the other end of the carrying plate 61, and the other end of the transmission belt 12 is fixedly connected to the unloading carrying plate 63.

[0036] The plastic steel pipe support assembly 7 includes a support plate 71 and a plurality of elastic limiting assemblies 72 installed on the upper end of the support plate 71 . A square steel pipe 9 is arranged on the outside of each elastic limiting assembly 72 . The wall thickness of the square steel pipe 9 is smaller than the distance between the outer cleaning assembly 4 and the inner cleaning assembly 5 .

[0037] Specifically, the loading cylinder 6 pushes the carrying plate 61 to move upward, driving the support plate 71 to move upward, so that the outer cleaning component 4 and the inner cleaning component 5 can clean the square steel pipe 9 inside and outside synchronously. At the same time, the downward pulling force of the carrying plate 61 on the transmission belt 12 disappears. At this time, under the action of the gravity of the loading carrying plate 62 or the unloading carrying plate 63, the transmission belt 12 rotates around the roller 11, and finally the loading carrying plate 62 or the unloading carrying plate 63 falls to the ground, and then the staff places the plastic steel pipe support assembly 7 with the square steel pipe 9 on the loading carrying plate 62. Before loading the square steel pipe 9 as a whole, the staff only needs to directly insert each square steel pipe 9 into the outside of the elastic limiting assembly 72. Remove the plastic steel pipe support assembly 7 on the unloading carrier plate 63, and simultaneously move the loading carrier plate 62 or the unloading carrier plate 63 downward while cleaning, so as to lower the position height of the loading carrier plate 62 or the unloading carrier plate 63, thereby facilitating the operator to load and unload materials. Similarly, when the loading cylinder 6 moves downward, the loading carrier plate 62 or the unloading carrier plate 63 moves up to the same horizontal plane as the carrier plate 61, and then pushes the corresponding plastic steel pipe support assembly 7 on the loading carrier plate 62 to move to the carrier plate 61, and at the same time, the plastic steel pipe support assembly 7 on the carrier plate 61 moves to the unloading carrier plate 63, completing the cleaning and replacement of the new square steel pipe 9 and removing the washed square steel pipe 9.

[0038] like Figure 4 and Figure 6 As shown, the external cleaning assembly 4 includes a hollow disk 41 and a guide tube 42 installed on the lower side of the hollow disk 41, the guide tube 42 is connected to the inner side of the hollow disk 41, an outer cleaning ring 43 is provided at one end of the guide tube 42 away from the hollow disk 41, the outer cleaning ring 43 is connected to the guide tube 42, and an outlet inclined downward is opened on the inner side of the outer cleaning ring 43.

[0039] like Figure 4 and Figure 6 As shown, the internal cleaning assembly 5 includes a central tube 51 and an internal cleaning disk 52 installed on the lower side of the central tube 51. The upper end of the central tube 51 is connected to the hollow disk 41, and the central tube 51 is connected to the internal cleaning disk 52. The upper end of the central tube 51 is connected to the branch tube 1 21 provided at the output end of the air inlet main tube 2 and the branch tube 2 31 provided at the output end of the water inlet main tube 3. At least two groups of stabilizing parts 53 are provided at the lower end of the central tube 51.

[0040] like Figure 6-Figure 8As shown, a transmission rod 54 is provided on the inner side of the central tube 51, an opening and closing valve 55 is provided on the upper end of the transmission rod 54, a ball 551 is rotatably provided on the inner side of the opening and closing valve 55, a spiral groove 541 is provided on the upper end of the transmission rod 54, the spiral groove 541 matches the ball 551, the opening and closing valve 55 is arranged in a columnar shape, a guide groove 552 is provided on one side of the opening and closing valve 55, the upper end of the opening and closing valve 55 is rotatably connected to the inner bottom of the central tube 51, a transmission head 58 is installed at the lower end of the transmission rod 54, a plurality of return springs 57 are installed on the upper end of the transmission head 58, the return spring 57 is located on the outer side of the transmission rod 54 and one end away from the transmission head 58 is fixedly connected to a support sheet 56 fixedly arranged on the inner side of the central tube 51.

[0041] Specifically, the feeding cylinder 6 pushes the bearing plate 61 to drive the square steel pipe 9 on the support plate 71 to move upward, and at the same time, the water inlet main pipe 3 passes the high-pressure water from the guide groove 552 and the output port of the branch pipe 31 into the center pipe 51 through the branch pipe 2 31, and the center pipe 51 transports the high-pressure water from the hollow plate 41 to the output port of the outer cleaning ring 43, and at the same time, the high-pressure water is also output from the inner cleaning plate 52. As the square steel pipe 9 moves upward, the outer cleaning ring 43 synchronously cleans the outer side of the square steel pipe 9, and the inner cleaning plate 52 synchronously cleans the inner side of the square steel pipe 9, and the stabilizing member 53 is mounted on the inner side of the square steel pipe 9 to stabilize the upward movement of the square steel pipe 9, so that the cleaning of the inside and outside of the square steel pipe 9 is stable and uniform. When the square steel pipe 9 moves upward, the transmission head 58 is connected to the upper end of the elastic limiting component 72 When the touch is on, the transmission head 58 pushes the transmission rod 54 upward in the opposite direction, thereby driving the spiral groove 541 to move upward, and under the guidance of the ball 551, the opening and closing valve 55 rotates. At this time, the branch pipe 2 31 is closed and the branch pipe 1 21 is opened, and the air intake main pipe 2 enters the high-pressure gas to blow and clean the large amount of water stains deposited on the lower ends of the inner and outer walls of the square steel pipe 9. Since the square steel pipe 9 is vertically arranged, the high-pressure water is also cleaned from top to bottom. The water stains remaining on the inner and outer walls of the square steel pipe 9 are mostly concentrated at the lower end of the square steel pipe 9. Water stains are easily accumulated on a small section of the inner and outer walls at the lower end of the square steel pipe 9. After the normal water stains evaporate, the stains will still remain temporarily. The water stains are blown downward by opening a jet at the bottom, thereby improving the cleaning effect of the square steel pipe 9.

[0042] like Figure 3 and Fig. 9As shown, the elastic limiting component 72 includes a sleeve 721 and a reset spring 722 fixedly installed on the inner side of the sleeve 721, a support column 723 is fixedly installed on the lower end of the reset spring 722, the support column 723 is fixedly connected to the inner bottom of the support plate 71, the sleeve 721 is sleeved on the outer side of the support column 723, the outer side of the sleeve 721 is tangent to the inner wall of the square steel pipe 9, and a lower push rod 724 is fixedly arranged in the middle of the elastic limiting component 72 in the middle of the support plate 71, the upper end of the lower push rod 724 passes through the middle of the reset spring 722 and is fixedly connected to the sleeve 721, and a frustum plug 725 is fixedly arranged on the lower end of the lower push rod 724, and the frustum plug 725 matches the middle part of the lower end of the support plate 71.

[0043] like Figure 2 and Fig.10 As shown, a wastewater collecting assembly 8 is also provided at the bottom of the supporting plate 61, and the wastewater collecting assembly 8 includes a collecting barrel 81 and a movable barrel 82 movably provided in the middle of the upper end of the collecting barrel 81, the upper end of the movable barrel 82 is fixedly connected to the middle of the supporting plate 61, and a through hole is opened in the middle of the supporting plate 61, and the through hole connects the movable barrel 82 and the bottom of the supporting plate 71, and a filter net 83 is provided at the inner lower end of the movable barrel 82.

[0044] Specifically, the water cleaned by the square steel pipe 9 will enter the inner side of the support plate 71. When the transmission head 58 is reversely squeezed to the limit, the sleeve 721 will be pushed downward, so that the sleeve 721 and the inner side of the square steel pipe 9 are gradually separated, which not only facilitates the outer cleaning ring 43 and the inner cleaning disc 52 to clean the lower end of the square steel pipe 9, but also drives the sleeve 721 to drive the lower push rod 724 to move downward, thereby driving the round table plug 725 to separate from the middle part of the lower end of the support plate 71, so that the inner side of the support plate 71 is connected with the movable barrel 82, and the cleaned water is diverted to the inside of the collection barrel 81 to complete the collection of the cleaning water. Moreover, when the support plate 71 with the washed square steel pipe 9 is manually removed, due to the blocking at the bottom of the middle part of the support plate 71, the small amount of water temporarily retained on the inner side of the support plate 71 will not flow out, which is convenient for the staff to operate;

[0045] Furthermore, when the carrier plate 61 moves up and down, the filter screen 83 also moves up and down in the water stored in the collection barrel 81, thereby causing the filter screen 83 to recoil, making the filter screen 83 less likely to be blocked and increasing its service life.

[0046] It should be noted that, in the description of the present application, it should be understood that the terms "length", "thickness", "inside", "outside", "axial", "radial", etc., indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
