Description

Technical Field

[0001] This invention relates to the field of road infrastructure and traffic equipment technology, and more specifically, to a road infrastructure and traffic bollard maintenance and renovation device. Background Technology

[0002] With the rapid development of transportation infrastructure construction, traffic bollards, as an important component of ensuring road safety and regulating traffic order, are increasing in number and usage frequency. Long-term exposure to the outdoor environment makes traffic bollards susceptible to wind, sun, rain erosion, and vehicle scratches, leading to problems such as rust, peeling of surface coatings, and structural damage.

[0003] Currently, the maintenance and renovation of traffic bollards are mostly carried out manually. Manual rust removal requires tools such as sandpaper and scrapers, which is inefficient and labor-intensive, and it's difficult to completely remove rust from the bollard surface. Manual painting results in uneven coating thickness and drips, affecting both aesthetics and protective effectiveness. Furthermore, manual inspection of bollard damage lacks precision and systematicity, easily leading to misjudgments or omissions, and manual maintenance and renovation cannot achieve efficient and standardized operations for bollards of different heights. Summary of the Invention

[0004] The purpose of this invention is to solve the problems mentioned in the background art, and to propose a road facility traffic bollard maintenance and renovation device.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A road infrastructure traffic bollard maintenance and renovation device includes a mobile structure, a control system mounted on the mobile structure, and a lifting structure installed on the mobile structure. The lifting structure is connected to an outer ring sleeve, and an inner ring sleeve, rotatably connected inside the outer ring sleeve, is connected to the outer ring sleeve via a drive structure, so that the inner ring sleeve fits around the bollard and can rotate and lift. The inner ring sleeve has a detection structure for detecting the degree of damage to the bollard, and the control system issues maintenance and renovation commands to the bollard based on the degree of damage. The inner ring sleeve also has a rust removal structure for executing the maintenance and renovation commands, and the rust removal structure extends below the inner ring sleeve and cooperates with the outside of the bollard to mechanically remove rust from the bollard. The outer ring sleeve has a spray structure located below the inner ring sleeve and connected to a functional structure, which is installed on the mobile structure and sequentially injects high-pressure gas and paint into the spray structure according to the maintenance and renovation commands.

[0007] Furthermore, the above scheme includes a telescopic cylinder 1 vertically mounted on the movable structure. The telescopic cylinder 1 is connected to a telescopic cylinder 2 with the opposite telescopic direction. The telescopic cylinder 2 is vertically mounted and its telescopic length is greater than that of the telescopic cylinder 1. An outer ring is horizontally mounted on the telescopic end of the telescopic cylinder 2. The cooperation between the telescopic cylinder 1 and the telescopic cylinder 2 enables the outer ring to perform a lifting action.

[0008] Furthermore, the above scheme includes an image recognition device and a size detector installed on the inner ring to detect cracks, peeling, damage, size and deformation on the surface of the road post, and transmit the detection data to the background control system in real time.

[0009] Furthermore, the above scheme involves extending the image recognizer and size detector beyond the bottom of the inner ring to ensure sufficient detection light and improve detection performance.

[0010] Furthermore, the above scheme includes a telescopic cylinder three vertically arranged inside the inner ring sleeve. The telescopic end of the telescopic cylinder three is connected to an installation ring. The diameter of the installation ring is smaller than that of the inner ring sleeve, and several telescopic cylinders four are arranged around the circumference of the installation ring. Each telescopic cylinder four is connected to a rust removal brush at its telescopic end to form a rust removal surface in contact with the road post inside the installation ring.

[0011] Furthermore, the above scheme includes a circular tube disposed on the outer ring sleeve, the circular tube being located below the inner ring sleeve and connected to the functional structure, and a plurality of nozzles being disposed around the circumference of the circular tube.

[0012] Furthermore, the above solution includes a conduit connected to a circular tube. The end of the conduit is connected to an air pipe and a paint guide pipe via a tee. A solenoid valve one is installed on the air pipe, and a solenoid valve two is installed on the paint guide pipe. When solenoid valve one is open, solenoid valve two is closed; when solenoid valve one is closed, solenoid valve two is open. The air pipe is connected to a fan mounted on a movable structure, and the paint guide pipe is connected to a liquid pump mounted on a movable structure. The liquid pump is connected to a paint tank mounted on a movable structure via a paint inlet pipe.

[0013] Furthermore, the above solution includes a liquid pipe connected to the paint inlet pipe, and a solenoid valve three is installed on the paint inlet pipe, and a solenoid valve four is installed on the liquid pipe. The solenoid valve three is open, the solenoid valve four is closed, the solenoid valve three is closed, the solenoid valve four is open, and the liquid pipe is connected to a rust removal liquid tank set on the movable structure to perform chemical rust removal on the road piles.

[0014] Furthermore, the above solution involves the coordinated operation of chemical and mechanical rust removal, with the fan blowing out hot air.

[0015] Furthermore, the above scheme includes a limiting structure on the outer ring to limit the downward travel of the lifting structure.

[0016] Furthermore, the limiting structure includes a mounting rod vertically mounted on the outer ring sleeve. An inner hole seat is slidably mounted on the bottom of the mounting rod. The inner hole seat is connected to the bottom of the mounting rod by a spring. A pressure sensor for contacting the bottom of the mounting rod is installed in the inner hole seat. When the pressure sensor reaches a set value, the lifting structure stops moving downward. A ball bearing for contacting the ground is also installed at the bottom of the inner hole seat.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention achieves significant benefits through the coordinated design and operation of its various structures; the mobile structure is equipped with a control system, enabling flexible movement and precise overall control of the equipment, ensuring that the equipment can quickly reach the work site and efficiently execute various commands; the lifting structure and drive structure work together to allow the inner ring to adapt to road bollards of different heights, achieving precise placement and rotational lifting actions, greatly improving the equipment's versatility and operational flexibility.

[0019] The detection structure can comprehensively and accurately detect the extent of damage to road bollards and transmit the data to the control system in real time, providing a reliable basis for scientific decision-making on whether to replace road bollards or carry out maintenance and renovation, thus avoiding unnecessary waste of resources and potential safety hazards.

[0020] During the rotation and lifting process, the rust removal structure can efficiently and thoroughly remove the rust layer on the surface of the road post. Compared with manual rust removal, the efficiency is greatly improved and the rust removal effect is better. The spray structure is linked with the functional structure. High-pressure gas and paint are injected in sequence according to the maintenance and renovation instructions. The surface of the road post is first cleaned to remove residual rust and dust, and then the paint is applied evenly to ensure that the road post has a beautiful appearance and good protective performance, effectively extending the service life of the road post.

[0021] The entire equipment integrates the maintenance and renovation processes such as inspection, rust removal, cleaning, and painting, realizing automated and standardized operations. It not only significantly improves the work efficiency of traffic bollard maintenance and renovation, reduces labor costs and labor intensity, but also ensures the quality of maintenance and renovation, providing strong support for the efficient maintenance of road facilities and the stability of traffic order.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The present invention will be further described with reference to the accompanying drawings and embodiments:

[0030] A road infrastructure traffic bollard maintenance and renovation device, as shown in the attached document. Figure 1 -Appendix Figure 3As shown, the device includes a mobile structure 1, on which a control system 11 is mounted. The mobile structure 1, equipped with the control system 11, enables the movement and overall control of the equipment. The control system 11 serves as the command center for the equipment. The mobile structure 1 and the control system 11 are existing technologies, and will not be elaborated upon further in this invention. The improvement of this invention lies in the addition of a lifting structure 2 on the mobile structure 1. The lifting structure 2 is connected to an outer ring sleeve 3. An inner ring sleeve 32, rotatably connected inside the outer ring sleeve 3, is connected to the outer ring sleeve 3 via a drive structure 31 (one of the existing belt drive, chain drive, or gear drive). This allows the inner ring sleeve 32 to be fitted onto the outside of the bollard and to perform rotational lifting movements, enabling the equipment to adapt to bollards of different heights and accurately fit the inner ring sleeve 32 onto the bollard. The inner ring sleeve 32 is equipped with a detection structure 4 for detecting the degree of damage to the bollard (determining whether to replace the bollard or perform maintenance, renovation, and reinforcement). The control system 1... 1. A maintenance and renovation instruction for the road post is issued based on the degree of damage, providing a basis for whether to replace the road post or carry out maintenance and renovation; the inner ring 32 is also equipped with a rust removal structure 5 (removing the rust layer caused by rusting on the surface of the road post) to execute the maintenance and renovation instruction, and the rust removal structure 5 extends to the bottom of the inner ring 32 and cooperates with the outside of the road post in the rust removal state; the outer ring 3 is equipped with a spray structure 6, which is located below the inner ring 32 and connected to a functional structure 7. The functional structure 7 is installed on the movable structure 1 and injects high-pressure gas (to clean the rust and dust adhering to the surface of the road post after rust removal) and paint (to paint the cleaned road post) into the spray structure 6 in sequence according to the maintenance and renovation instruction. According to the maintenance and renovation instruction, the functional structure 7 first injects high-pressure gas into the spray structure 6 to clean the surface of the road post after rust removal, remove residual rust and dust, and then injects paint to paint the cleaned road post, restoring the appearance and protective performance of the road post.

[0031] The specific operating procedure is as follows:

[0032] 1. Use the moving structure 1 to move the equipment to the vicinity of the road post to be maintained and renovated, and use the lifting structure 2 to put the inner ring 32 on the road post and adjust it to a suitable height;

[0033] 2. The lifting structure 2, the drive structure 31 and the detection structure 4 are activated, causing the detection structure 4 to rotate and lift to comprehensively detect the damage to the road bollard. The detection structure 4 transmits the detection data to the control system 11. The control system 11 determines whether the road bollard needs to be replaced or maintained and refurbished according to the preset standards.

[0034] 3. If maintenance and renovation are required, the lifting structure 2, the drive structure 31 and the rust removal structure 5 will be activated, causing the rust removal structure 5 to rotate and lift to remove the rust layer on the surface of the road post.

[0035] 4. After rust removal is completed, the lifting structure 2 and the functional structure 7 operate, causing the spray structure 6 to lift and lower, while spraying high-pressure gas to clean the surface of the road post and remove residual rust and dust.

[0036] 5. After cleaning is completed, the lifting structure 2 and the functional structure 7 operate, causing the spray structure 6 to lift and spray paint to coat the road posts.

[0037] 6. After the painting is completed, shut down the functional structure 7, and continue to operate the lifting structure 2 to remove the inner ring 32 and the spray structure 6 from the road post. Use the moving structure 1 to remove the equipment from the site.

[0038] For the above scheme, please refer to the appendix for details. Figure 1 As shown, the lifting structure 2 includes a telescopic cylinder 21 vertically mounted on the moving structure 1. The telescopic end of the telescopic cylinder 21 is connected to a telescopic cylinder 22 with the opposite telescopic direction. The telescopic cylinder 22 is vertically mounted and its telescopic length is greater than that of the telescopic cylinder 21. The outer ring sleeve 3 is horizontally mounted on the telescopic end of the telescopic cylinder 22. The cooperation between the telescopic cylinder 21 and the telescopic cylinder 22 enables the outer ring sleeve 3 to perform lifting and lowering actions. When both the telescopic cylinder 21 and the telescopic cylinder 22 are in the retracted state, the outer ring sleeve 3 and the structure connected to it are in the retracted state, reducing the volume occupied by the equipment.

[0039] When it is necessary to raise the outer ring sleeve 3, the telescopic cylinder 21 first extends, driving the outer ring sleeve 3 to adjust to a suitable working height. When a maintenance or refurbishment command is issued, the telescopic cylinder 22 performs a lifting action according to actual needs. Through this collaborative working method, the outer ring sleeve 3 can be flexibly raised and lowered within a certain range. When both the telescopic cylinder 21 and the telescopic cylinder 22 are in the retracted state, the retraction of the telescopic cylinder 21 and the telescopic cylinder 22 causes the outer ring sleeve 3 to drop to the lowest position, reducing the height of the equipment in the non-working state, which facilitates the transportation and storage of the equipment. At the same time, this retracted state is also conducive to the protection of the equipment, avoiding collisions and damage to the components during transportation and storage.

[0040] For the above scheme, please refer to the appendix for details. Figure 1 and attached Figure 2 As shown, the detection structure 4 includes an image recognizer 41 and a size detector 42 mounted on the inner ring 32. The image recognizer 41 and the size detector 42 protrude from the bottom of the inner ring 32 to ensure sufficient light for detection and improve the detection effect. The image recognizer 41 analyzes the damage such as cracks and peeling on the surface of the road post through image recognition technology, while the size detector 42 is used to measure the size and deformation of the road post, thereby accurately judging the degree of damage to the road post. The two work together to perform rapid and efficient detection of the road post, and at the same time, the detection data is transmitted to the background control system 11 in real time.

[0041] In this system, the image recognition device 41, in its rotating and lifting state, primarily focuses on the damage to the surface of the bollard, while the size detector 42 focuses on the size and deformation of the bollard. The two complement each other, enabling a comprehensive assessment of the bollard's damage level. (For example, when cracks appear on the surface of the bollard, the image recognition device 41 can detect the presence and characteristics of the cracks, while the size detector 42 can measure the impact of the cracks on the size and structure of the bollard, thus more accurately determining the degree of damage.) The image recognition device 41 and the size detector 42 transmit the detected data to the background control system 11 in real time. The background control system 11 integrates and analyzes this data, and by comprehensively considering the damage to the surface of the bollard and the size deformation, it arrives at an overall assessment result of the bollard's damage level. This real-time data transmission and integration provides an accurate and timely basis for bollard maintenance and renovation decisions.

[0042] For the above scheme, please refer to the appendix for details. Figure 1 and attached Figure 2 As shown, the rust removal structure 5 includes a telescopic cylinder 3 51 vertically arranged inside the inner ring sleeve 32. The telescopic end of the telescopic cylinder 3 51 is connected to an installation ring 52. The diameter of the installation ring 52 is smaller than that of the inner ring sleeve 32, and a number of telescopic cylinders 4 53 are arranged around the circumference of the installation ring 52. Each telescopic cylinder 4 53 is connected to a rust removal brush 54 at its telescopic end to form a rust removal surface in contact with the road post inside the installation ring 52.

[0043] Among them, the telescopic cylinder 3 51 is vertically installed in the inner ring sleeve 32. Its telescopic end is connected to the mounting ring 52 with a diameter smaller than the inner ring sleeve 32. The telescopic cylinder 3 51 can extend the mounting ring 52 out of the inner ring sleeve 32 for operation or store it in the inner ring sleeve 32. Several telescopic cylinders 4 53 are circumferentially distributed on the mounting ring 52. Each telescopic end is connected to a rust removal brush 54. The telescopic cylinders 4 53 can control the radial extension and retraction of the rust removal brush 54 to adapt to road piles of different diameters. Multiple telescopic cylinders 4 53 drive the rust removal brush 54 to form a rust removal surface that fits the road pile surface in the mounting ring 52. When the mounting ring 52 rotates with the inner ring sleeve 32, the rust layer on the road pile surface is efficiently removed.

[0044] For the above scheme, please refer to the appendix for details. Figure 1 and attached Figure 2 As shown, the jet structure 6 includes a circular tube 61 disposed on the outer ring sleeve 3. The circular tube 61 is located below the inner ring sleeve 32 and connected to the functional structure 7. A plurality of nozzles 62 are disposed on the circumference of the circular tube 61.

[0045] Among them, the circular tube 61, which is set on the outer ring 3 and located below the inner ring 32, is connected to the functional structure 7 and receives high-pressure gas and paint injected by the functional structure 7 in the order of maintenance and renovation instructions. Several nozzles 62 distributed around the circumference of the circular tube 61 can evenly spray the high-pressure gas or paint entering the circular tube 61 onto the surface of the road post, so as to clean the rust and dust on the surface of the road post after rust removal, and to paint the road post after cleaning.

[0046] For the above scheme, please refer to the appendix for details. Figure 1 and attached Figure 3 As shown, the functional structure 7 includes a conduit 71 connected to the annular pipe 61. The end of the conduit 71 is connected to an air pipe 73 and a paint guide pipe 74 via a tee 72. A solenoid valve 731 is installed on the air pipe 73, and a solenoid valve 741 is installed on the paint guide pipe 74. When the solenoid valve 731 is open, the solenoid valve 741 is closed, and vice versa. The air pipe 73 is connected to a fan 75 installed on the movable structure 1, and the paint guide pipe 74 is connected to a liquid pump 76 installed on the movable structure 1. The liquid pump 76 is connected to a paint tank 78 installed on the movable structure 1 via a paint inlet pipe 77.

[0047] In this process, a conduit 71 connects to a circular pipe 61. A tee 72 at the end of the conduit 71 separates the air pipe 73 and the paint guide pipe 74, enabling independent transmission of gas and paint. The solenoid valve 731 on the air pipe 73 and the solenoid valve 741 on the paint guide pipe 74 act as control switches, coordinating different work processes. When the solenoid valve 731 is open and the solenoid valve 741 is closed, the high-pressure gas generated by the fan 75 on the moving structure 1 is transported to the circular pipe 61 through the air pipe 73 and the conduit 71, and sprayed out through the nozzle 62 to clean the surface of the road post after rust removal. When painting is required, the solenoid valve 731 is closed and the solenoid valve 741 is opened. The liquid pump 76 draws paint from the paint tank 78 and injects it into the circular pipe 61 through the paint inlet pipe 77, the paint guide pipe 74, and the conduit 71. The nozzle 62 then sprays the paint evenly onto the road post. In this way, the cleaning and painting operations are completed in an orderly manner according to the maintenance and renovation instructions.

[0048] In order to improve the functional effect of functional structure 7 in the above scheme, please refer to the appendix. Figure 4As shown, the functional structure 7 also includes a liquid pipe 79 connected to the paint inlet pipe 77, and a solenoid valve 771 is installed on the paint inlet pipe 77. A solenoid valve 791 is installed on the liquid pipe 79. When the solenoid valve 771 is open, the solenoid valve 791 is closed, and vice versa. The liquid pipe 79 is connected to a rust removal liquid tank 710 set on the movable structure 1. The liquid pump 76 draws rust removal liquid from the rust removal liquid tank 710 and injects it into the annular pipe 61 through the liquid pipe 79, the paint guide pipe 74, and the conduit 71. The rust removal liquid is evenly sprayed onto the road post by the nozzle 62, thereby realizing the chemical rust removal operation on the road post. The chemical rust removal operation can be carried out simultaneously with the mechanical rust removal operation. After the rust removal operation is completed, the cleaning and painting operation begins. In addition, considering the rapid drying operation of the road post surface after chemical rust removal, the fan 75 blows out hot air.

[0049] In this structure, functional structure 7 is supplemented by a liquid pipe 79 connected to the paint inlet pipe 77. The solenoid valve 3 771 on the paint inlet pipe 77 and the solenoid valve 4 791 on the liquid pipe 79 are linked for control. By switching between their opening and closing, the function of paint delivery and rust removal fluid delivery is realized. When the solenoid valve 3 771 is closed and the solenoid valve 4 791 is open, the liquid pump 76 draws rust removal fluid from the rust removal fluid tank 710 on the mobile structure 1 and injects it into the annular pipe 61 through the liquid pipe 79, the paint guide pipe 74, and the guide pipe 71. The fluid is then sprayed onto the surface of the road post by the nozzle 62 to complete the chemical rust removal operation. This operation can be carried out in parallel with the mechanical rust removal operation. After the rust removal operation is completed, the solenoid valve state is switched to perform cleaning and painting operations. At the same time, the hot air blower 75 on the mobile structure 1 blows out hot air after chemical rust removal to accelerate the drying of the road post surface, creating good conditions for subsequent cleaning and painting, and ensuring that the entire maintenance and renovation process is carried out efficiently and in an orderly manner.

[0050] Regarding the above solutions, considering the stability and safety of the equipment, please refer to the appendix for details. Figure 5 and attached Figure 6 As shown, the outer ring sleeve 3 is provided with a limiting structure 8 to limit the downward stroke of the lifting structure 2. The limiting structure 8 includes a mounting rod 81 vertically arranged on the outer ring sleeve 3. An inner hole seat 82 is slidably arranged at the bottom of the mounting rod 81. The inner hole seat 82 is connected to the bottom of the mounting rod 81 by a spring 83. A pressure sensor 84 for contacting the bottom of the mounting rod 81 is installed in the inner hole seat 82. When the pressure sensor 84 reaches the set value, the lifting structure 2 stops its downward movement. In addition, a ball bearing 85 for contacting the ground is also installed at the bottom of the inner hole seat 82.

[0051] In this system, an installation rod 81 is vertically mounted on the outer ring sleeve 3. The bottom of the installation rod 81 is slidably connected to the inner hole seat 82, and the two are connected by a spring 83. A pressure sensor 84 is installed inside the inner hole seat 82, which contacts the bottom of the installation rod 81. A ball bearing 85 is installed at the bottom, which contacts the ground, thus achieving equipment stability and safety protection. When the lifting structure 2 moves down, the inner hole seat 82 first contacts the ground, and the ball bearing 85 reduces friction. As it continues to move down, the spring 83 is compressed, causing the installation rod 81 to contact the pressure sensor 84 and generate pressure. When the pressure sensor 84 reaches the set value, it means that the lifting structure 2 has reached the limit position. After receiving the signal, the control system 11 immediately controls the lifting structure 2 to stop moving down, thereby effectively limiting the downward stroke of the lifting structure 2 and ensuring the stability and safety of the equipment operation.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention. The scope of protection of the present invention is defined by the appended claims and their equivalents.
