Description

Technical Field

[0001] This utility model belongs to the field of building cleaning technology, and in particular relates to a surface cleaning device for prefabricated cross-sea piers. Background Technology

[0002] Before painting existing prefabricated bridge piers, surface cleaning is crucial. Typically, their surfaces may contain numerous impurities and defects, such as dust, oil, and rust. If these impurities are not effectively removed, they will severely affect the paint application, preventing the paint from adhering evenly to the pier surface and causing patchy or peeling coatings, thus impacting the pier's corrosion resistance and aesthetics. Similarly, for negative pressure adsorption robots used for adsorption spraying, a clean surface is key to ensuring stable adsorption and precise spraying. However, current conventional cleaning methods still largely rely on manual labor, which has several drawbacks. For example, cleaning efficiency is low, and manual cleaning requires significant time and manpower, especially when dealing with large-scale bridge piers, where the cleaning process becomes even more lengthy. Furthermore, manual labor poses certain safety risks; workers performing work at heights or on water require strict safety measures, which also hinders cleaning efficiency. Utility Model Content

[0003] In view of this, the present invention aims to propose a surface cleaning device for prefabricated cross-sea piers to solve the problem of low cleaning efficiency in the existing surface cleaning of prefabricated cross-sea piers.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A prefabricated pier surface cleaning device for cross-sea use includes a main frame and a secondary frame, with the secondary frame rotatably mounted on one end of the main frame. Both the main frame and the secondary frame have a hanger above them and a limiting component corresponding to the hanger below them, capable of engaging with the pier surface. The hanger has a lifting ring for connecting a lifting rope on its side away from the pier surface, and a guide wheel for engaging with the lifting rope on its other side. The guide wheel is rotatably mounted on the hanger, and a clearance exists between the hanger and the guide wheel to facilitate the passage of the lifting rope. Both the main frame and the secondary frame have a cleaning mechanism, which includes a brush roller rotatably mounted on the corresponding main frame or secondary frame. Both the main frame and the secondary frame have a drive assembly for driving the brush roller to rotate. A spraying assembly is located on the limiting component below the brush roller.

[0005] Furthermore, two hangers are provided at each of the left and right ends of the main frame or the auxiliary frame, and the limiting members are provided one-to-one with the hangers.

[0006] Furthermore, the hanger is an L-shaped structural component, with the vertical end of the hanger fixed to the main frame or the secondary frame, and the horizontal end set away from the surface of the pier column; the lifting ring is set on the horizontal end of the hanger, and the guide wheel is rotatably installed on the vertical end of the hanger, with an assembly groove for installing the guide wheel on the vertical end of the hanger.

[0007] Furthermore, the limiting member is provided with rollers on the side facing the pier, and multiple rollers are spaced apart along the length of the limiting member.

[0008] Furthermore, both the limiting member and the hanger are provided with reinforcing plates. One end of the reinforcing plate is connected to the corresponding limiting member or hanger, and the other end is connected to the corresponding main frame or sub-frame.

[0009] Furthermore, the cleaning mechanism also includes a cleaning roller that cooperates with the brush roller. The cleaning roller is rotatably mounted on the corresponding main frame or sub-frame. The cleaning roller is positioned on the side of the brush roller away from the surface of the pier, and the rotation direction of the cleaning roller is opposite to that of the brush roller. The drive assembly drives the cleaning roller to rotate through the transmission assembly.

[0010] Furthermore, mudguards are provided on both the main frame and the sub-frame at positions above the cleaning roller, and liquid collection tanks are provided on both the main frame and the sub-frame at positions below the cleaning roller. Drainage pipes communicating with the liquid collection tanks are provided at the bottom of both the main frame and the sub-frame.

[0011] Furthermore, the spray assembly includes a spray pipe and a liquid supply hose connected to the spray pipe, and the spray pipe is provided with a plurality of nozzles on the side facing the surface of the pier.

[0012] Furthermore, the nozzle is obliquely positioned on the spray pipe, with one obliquely downward end of the nozzle facing the surface of the bridge pier.

[0013] Compared with existing technologies, the prefabricated cross-sea pier surface cleaning device of this utility model has the following advantages: This utility model discloses a prefabricated pier surface cleaning device for cross-sea operations. It can be used for cleaning pier surfaces, offering advantages such as good cleaning effect, ease of operation, and minimal environmental pollution. By employing a rotatable sub-frame mounted on the main frame, this cleaning device can adapt to not only curved pier surfaces but also effectively clean corners, improving its applicability to piers of various shapes.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] A prefabricated cross-sea pier surface cleaning device, such as Figures 1 to 3 As shown, the system includes a main frame 1 and a secondary frame 2, with the secondary frame 2 rotatably mounted on one end of the main frame 1. Both the main frame 1 and the secondary frame 2 have a hanger 3 above them and a limiting member 8 below them, corresponding to the hanger 3, that can engage with the surface of the pier. The hanger 3 has a lifting ring 5 for connecting a lifting rope on one side away from the pier surface, and a guide wheel 4 for engaging with the lifting rope on the other side. The guide wheel 4 is rotatably mounted on the hanger 3, and there is a passage gap between the hanger 3 and the guide wheel 4 to facilitate the passage of the lifting rope. Both the main frame 1 and the secondary frame 2 are equipped with a cleaning mechanism, which includes a brush roller 13. The brush roller 13 is rotatably mounted on the corresponding main frame 1 or secondary frame 2. Both the main frame 1 and the secondary frame 2 are equipped with a driving assembly 7 for driving the brush roller 13 to rotate. A spraying assembly is located on the limiting member 8 below the brush roller 13.

[0021] For example, the sub-frame 2 can be rotatably mounted on the end of the main frame 1 via a rotating shaft. A rotating shaft seat that mates with the rotating shaft is fixed on the main frame 1. Those skilled in the art can also choose a suitable method to install the sub-frame 2 according to actual needs, thereby achieving a rotatable connection between the sub-frame 2 and the main frame 1. In actual use, by rotating the sub-frame 2, the operator can make this cleaning device adaptable not only to the curved surface of the pier but also to effectively clean the corners of the pier surface, thus improving the applicability of this cleaning device to piers of different shapes.

[0022] In practical applications, this cleaning device needs to be used in conjunction with hoisting equipment and ropes. The operator first connects the rope to the lifting ring 5 via a common connecting ring, then passes it through the gap between the guide wheel 4 and the hanger 3, allowing the rope to slide against the guide wheel 4. At this point, the rope bends at the guide wheel 4. During hoisting, the portion of the rope passing through the guide wheel 4 remains vertical, while the portion connecting the rope to the lifting ring 5 remains inclined. This allows the rope to exert an upward force on the guide wheel 4 and the upper end of the hanger 3. Under this force, the limiting member 8 can limit the main frame 1 or the secondary frame 2 by pressing against the surface of the pier, ensuring that the brush roller 13 continuously adheres to the pier surface for cleaning, thus improving the cleaning effect of this device on the pier surface.

[0023] In addition, if necessary, a pull rope can be installed on the lifting ring 5 to limit and protect the entire device. By using the reel equipment on the bottom to wind up the pull rope, a force is applied to the lifting frame 3 toward the surface of the pier to ensure the cleaning effect. Those skilled in the art can adjust the lifting method according to actual needs, which will not be elaborated here.

[0024] In an optional embodiment, a limiting mechanism (not shown in the figure) for locking the rotation of the sub-frame 2 can be installed on the main frame 1 to ensure that the angle between the sub-frame 2 and the main frame 1 remains unchanged after the sub-frame 2 rotates. This improves the safety of the cleaning device during hoisting and ensures that the cleaning device can more stably clean the surface of the pier. Those skilled in the art can select a suitable limiting mechanism according to actual needs to limit the rotation of the sub-frame 2, which will not be elaborated here.

[0025] In another optional embodiment, a drive mechanism (not shown in the figure) for driving the rotation of the sub-frame 2 can also be installed on the main frame 1. For example, a telescopic cylinder, one end of which is rotatably mounted on the main frame 1, and the other end is rotatably connected to the sub-frame 2. This allows the sub-frame 2 to rotate relative to the main frame 1 when the telescopic cylinder extends, adjusting the angle between the main frame 1 and the sub-frame 2. This allows the cleaning mechanisms on the main frame 1 and the sub-frame 2 to better fit against the pier surface, achieving effective cleaning of the pier surface. Those skilled in the art can also select other suitable drive mechanisms according to actual needs to drive the sub-frame 2 to rotate; these will not be elaborated upon here.

[0026] Preferably, two hangers 3 are provided at the left and right ends corresponding to the main frame 1 or the auxiliary frame 2, and the limiting members 8 are provided one-to-one with the hangers 3. Specifically, the hanger 3 is an L-shaped structural member, with its vertical end fixed to the main frame 1 or the auxiliary frame 2, and its horizontal end set away from the surface of the pier column; the lifting ring 5 is set on the horizontal end of the hanger 3, and the guide wheel 4 is rotatably installed on the vertical end of the hanger 3, with an assembly groove for installing the guide wheel 4 on the vertical end of the hanger 3. The guide wheel 4 can be rotatably installed on the hanger 3 by conventional means such as a rotating shaft, and there is a clearance between the guide wheel 4 and the bottom surface of the assembly groove, and the clearance communicates with the assembly groove.

[0027] By fixing two hangers 3 at both ends of the main frame 1 or the auxiliary frame 2, and fixing two limiting parts 8 accordingly, it is beneficial to improve the stability of the main frame 1 and the auxiliary frame 2 during the hoisting process, and ensure that the limiting parts 8 can continuously and stably limit the main frame 1 and the auxiliary frame 2.

[0028] Preferably, the limiting member 8 is provided with a roller 9 on the side facing the pier, and multiple rollers 9 are spaced apart along the length of the limiting member 8. For example, two or more rollers 9 may be spaced apart, and each roller 9 can be rotatably mounted on the limiting member 8 by a conventional means such as a rotating shaft. The limiting member 8 may be provided with a wheel seat or mounting groove for mounting the roller 9.

[0029] In actual use, by rotating and installing multiple rollers 9 on the limiting member 8, the friction between the limiting member 8 and the pier surface can be changed from sliding friction to rolling friction, preventing the limiting member 8 from damaging the pier surface during the movement of this cleaning device, thereby avoiding affecting the subsequent painting effect on the pier surface.

[0030] Preferably, both the limiting member 8 and the hanger 3 are provided with reinforcing plates 6. One end of the reinforcing plate 6 is connected to the corresponding limiting member 8 or hanger 3, and the other end is connected to the corresponding main frame 1 or sub-frame 2. For example, one end of the reinforcing plate 6 on the limiting member 8 is fixed to the limiting member 8, and the other end is fixed to the main frame 1 or sub-frame 2. The same applies to the reinforcing plate 6 on the hanger 3, which will not be described in detail here.

[0031] In practical applications, by setting the reinforcing plate 6, it is beneficial to improve the connection strength between the hanger 3 and the main frame 1, between the hanger 3 and the auxiliary frame 2, between the limiting member 8 and the main frame 1, and between the limiting member 8 and the auxiliary frame 2, so as to ensure that the hanger 3 can continuously and stably lift the cleaning device, and to ensure that the limiting member 8 can continuously and stably achieve the limiting by pressing against the surface of the pier column.

[0032] Preferably, the cleaning mechanism further includes a cleaning roller 16 that cooperates with the brush roller 13. The cleaning roller 16 is rotatably mounted on the corresponding main frame 1 or sub-frame 2. The cleaning roller 16 is set on the side of the brush roller 13 away from the surface of the pier, and the rotation direction of the cleaning roller 16 is opposite to the rotation direction of the brush roller 13. The driving component 7 drives the cleaning roller 16 to rotate through the transmission component.

[0033] For example, both the brush roller 13 and the cleaning roller 16 can be rotatably mounted on the main frame 1 and the sub-frame 2 via conventional means such as a rotating shaft. The drive component 7 can be a drive motor, and the transmission component can be a gear transmission mechanism. For example, the drive motor is fixed on the corresponding main frame 1 or sub-frame 2, and the output end of the drive motor is provided with a driving gear 17. Both the brush roller 13 and the cleaning roller 16 are fixed with driven gears 18 that cooperate with the driving gear 17, so that when the drive motor drives the driving gear 17 to rotate, it drives the brush roller 13 and the cleaning roller 16 to rotate respectively. The power supply and control methods of the drive motor are existing technologies and will not be described in detail here. In addition, those skilled in the art can also select appropriate drive components and transmission components according to actual needs to achieve the rotation of the brush roller 13 and the cleaning roller 16, which will also not be described in detail here.

[0034] In practical applications, operators can use hoisting equipment to lift this cleaning device to the top of the pier, and then gradually move it downwards. During this downward movement, the spray assembly first rinses and cleans the pier surface, wetting the dust and oil. Then, the rotating brush roller 13 continuously scrubs the pier surface to remove mud, oil, and rust. Furthermore, the wetting of the dust during this process reduces dust pollution. Simultaneously, because the cleaning roller 16 and the brush roller 13 rotate in opposite directions, their close contact allows the rotating cleaning roller 16 to effectively scrape away wastewater and foreign matter from the brush roller 13, improving the continuous cleaning effect of the brush roller 13 on the pier surface.

[0035] Preferably, mudguards 19 are provided on the main frame 1 and the sub-frame 2 at positions above the cleaning roller 16, and collection tanks 14 are provided on the main frame 1 and the sub-frame 2 at positions below the cleaning roller 16. A drain pipe 15 communicating with the collection tank 14 is provided below the main frame 1 and the sub-frame 2. Exemplarily, the mudguards 19 and the collection tank 14 are both fixed to the corresponding main frame 1 or sub-frame 2, and the drain pipe 15 is fixed to the collection tank 14. In actual use, a flexible hose can be used to connect the drain pipe 15 to facilitate the rapid and safe discharge of wastewater from the collection tank 14. The wastewater discharged from the drain pipe 15 can be collected by wastewater treatment or collection equipment on the bottom of the pier.

[0036] During the actual cleaning of the pier surface using the brush roller 13, the rotating brush roller 13 and cleaning roller 16 also drive the sewage towards the main frame 1 or the secondary frame 2. At this time, the mudguard 19 can effectively block and guide the sewage, guiding it into the collection tank 14 and finally discharging it through the drain pipe 15. By using the collection tank 14 to collect the sewage thrown out by the brush roller 13 and cleaning roller 16, not only can sewage splashing be avoided from affecting the surface of other piers or polluting the environment, but it can also prevent sewage from falling from a height and causing damage to personnel, structures, and equipment at the pier base.

[0037] Preferably, the spray assembly includes a spray pipe 10 and a liquid supply hose 12 communicating with the spray pipe 10. The spray pipe 10 has a plurality of nozzles 11 on the side facing the pier surface. Exemplarily, the spray pipe 10 can be fixed to the limiting member 8, and the liquid supply hose 12 can be connected to the spray pipe 10 using conventional methods such as clamps. The nozzles 11 can be installed and fixed to the spray pipe 10 using conventional methods such as threaded connections. Those skilled in the art can choose appropriate methods to install the above components according to actual needs, which will not be elaborated here.

[0038] In practical applications, the nozzle 11 is angled downwards on the spray pipe 10, with the angled end of the nozzle 11 facing the surface of the pier. Connected to an external water supply device via the supply hose 12, water can be continuously supplied to the spray pipe 10, allowing the nozzle 11 to spray water at an angle towards the pier surface. This achieves efficient cleaning of the pier surface, washing away most of the dust and oil, which helps reduce the subsequent cleaning difficulty of the brush roller 13.

[0039] This utility model discloses a prefabricated pier surface cleaning device for cross-sea operations. It can be used for cleaning pier surfaces, offering advantages such as good cleaning effect, ease of operation, and minimal environmental pollution. By employing a rotatable sub-frame mounted on the main frame, this cleaning device can adapt to not only curved pier surfaces but also effectively clean corners, improving its applicability to piers of various shapes. Furthermore, the combination of the cleaning mechanism and spray assembly not only enhances the cleaning effect but also prevents dust generation, thus improving the construction environment.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
