Description

Technical Field

[0001] The invention belongs to the technical field of guardrail cleaning equipment, and in particular relates to a road bridge guardrail cleaning device. Background Art

[0002] Road guardrail cleaning is an important part of maintaining the appearance and function of urban road and bridge guardrails. As an important safety facility of roads and bridges, guardrails are exposed to the environment for a long time and are prone to accumulate dust, mud, dirt and other pollutants. These pollutants not only affect the appearance of the guardrail, but may also affect its protective function. Therefore, it is necessary to clean the road guardrail regularly. Existing road guardrail cleaning is mainly carried out by manual cleaning and automated equipment.

[0003] At present, common methods for cleaning road guardrails include manual cleaning and cleaning with vehicle-mounted parallel roller brush automated equipment. Manual cleaning usually requires cleaning personnel to use high-pressure water guns, brushes and other tools to clean the guardrails section by section. Although this method can clean more thoroughly, it is inefficient, labor-intensive, and has certain safety hazards.

[0004] The vehicle-mounted parallel roller brush automation equipment is a relatively advanced cleaning method. It is usually installed on a special cleaning vehicle and cleans the surface of the guardrail with a parallel roller brush. The equipment uses the rotating motion of the roller brush to rub and clean the surface of the guardrail, which can reduce manual labor to a certain extent. However, the existing vehicle-mounted parallel roller brush equipment has limited cleaning effect when facing guardrails with complex shapes. For example, for guardrails with complex shapes (such as guardrails with arc or broken line shapes), the existing parallel roller brush automation equipment is difficult to cover the concave and arc areas of the guardrail, resulting in incomplete cleaning and still requiring manual assistance for cleaning. The existing equipment has poor adaptability to the shape of the guardrail, especially for vertical guardrails and non-linear guardrails, which are difficult to achieve comprehensive cleaning. Due to the unsatisfactory cleaning effect of the existing equipment, a large amount of manual assistance is still required, which increases the labor intensity and operation time, and there are safety hazards. The existing cleaning equipment lacks intelligent obstacle avoidance function and is prone to collision with the guardrail column during the cleaning process, affecting the continuity of operation and the life of the equipment.

[0005] Based on the structural form of the above-mentioned road and bridge guardrails, it is difficult to achieve efficient and comprehensive cleaning with existing technology. Therefore, it is necessary to develop an efficient, intelligent and comprehensive guardrail cleaning device to reduce manual intervention, improve cleaning effect and efficiency, and ensure operation safety.

DETAILED DESCRIPTION

[0031] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0032] Embodiment 1: A road bridge guardrail cleaning device, such as Figure 1 - 4, it includes a vehicle body 1, a storage box 2, a main clamping assembly 3, a rolling washing mechanism 4, an auxiliary clamping assembly 5, a reciprocating assembly 6 and a manipulator assembly 7, etc. When moving between adjacent guardrail posts, with the help of the power of the vehicle body 1 moving forward, the rolling washing mechanism 4 at the end of the main clamping assembly 3 and the auxiliary clamping assembly 5 can be respectively buckled on the outside of the corresponding railings, and translated along their respective railings without leaving the guardrails, so that the rolling washing mechanism 4 at the end of the main clamping assembly 3 and the auxiliary clamping assembly 5 can be used as a track to provide translation guidance. When it is necessary to cross the guardrail post, the rolling washing mechanism 4 at the end of the main clamping assembly 3 and the auxiliary clamping assembly 5 is controlled to be unfolded respectively, and the sliding frame 22 is retracted a short distance backward relative to the fixed outer box 21 to avoid the guardrail post. As the vehicle body 1 continues to move forward, after avoiding the post, the sliding frame 22 moves forward again relative to the fixed outer box 21, so that the rolling washing mechanism 4 at the end of the main clamping assembly 3 and the auxiliary clamping assembly 5 is respectively buckled on the outside of the corresponding railings.

[0033] like Figure 2As shown, the vehicle body 1 includes a frame 11, running wheels 12, a water supply system 13 and an assembly area 14. The water supply system 13 includes a water tank, a high-pressure water pump and a high-pressure water pipe. The water supply system 13 is installed on the upper side of the frame 11, and the running wheels 12 are installed at the bottom of the frame 11. On the upper side of the frame 11, an installation and assembly area 14 is set in an area away from the running wheels 12 and the water supply system 13, and a storage box 2 is installed in the assembly area 14.

[0034] like Figure 3 and Figure 4 As shown, the storage box 2 includes a fixed outer box 21, a sliding frame 22, a track 23, a track wheel 24, a track motor 25 and a fixed seat 26. The sliding frame 22 is set in the fixed outer box 21, and the track 23 is fixed horizontally on the left and right side walls of the fixed outer box 21, and the track wheels 24 are installed on the left and right outer side walls of the sliding frame 22. The track motor 25 is fixed on the inner side of the sliding frame 22, and the rotating shaft of the track motor 25 is connected with the rotating shaft of the corresponding track wheel 24, so that when the controller controls the rotating shaft of the track motor 25 to rotate, it can drive the track wheel 24 to roll along the track 23, and then, the sliding frame 22 can be telescopically moved in the fixed outer box 21. When cleaning, the sliding frame 22 extends from the fixed outer box 21 and is located at the edge of the fixed outer box 21. When not in operation, the sliding frame 22 shrinks to the bottom of the inner side of the fixed outer box 21. Two main clamping components 3 are installed on the upper side of the sliding frame 22, and two auxiliary clamping components 5 are installed on the lower side. The end of the main clamping assembly 3 and the end of the auxiliary clamping assembly 5 are respectively installed with a rolling washing mechanism 4.

[0035] like Figure 5 , Figure 7 and Figure 8As shown, the main clamping assembly 3 includes a lifting seat 31, a main frame screw sleeve 32, a screw 33, a guide rod 34, a main frame outer sleeve 35, a main frame inner sleeve 36 and an adjustment lock wire 37. A pair of lifting seats 31 are respectively provided with a main frame screw sleeve 32 in the middle, and guide holes are respectively provided at symmetrical positions on both sides of the main frame screw sleeve 32. The screw 33 is matched and installed in the main frame screw sleeve 32, and the guide rod 34 is matched and installed in the guide hole. The upper and lower ends of the guide rod 34 are respectively fixed to the upper bottom plate and the lower bottom plate of the sliding frame 22, and the upper and lower ends of the screw 33 are respectively installed at the upper center and the lower center of the sliding frame 22 through the shaft sleeve. A lifting motor 38 is fixedly installed on the top of the sliding frame 22, and the rotating shaft of the lifting motor 38 is connected to the screw 33. When the controller controls the lifting motor 38 to rotate, the screw 33 can be controlled to rotate. The main frame screw sleeve 32 located at the center of the two lifting seats 31 has opposite thread directions, so that when the screw rod 33 rotates, the two lifting seats 31 move away or move closer respectively. A main frame outer sleeve 35 is vertically fixed in the middle of the outer end of each lifting seat 31, and a main frame inner sleeve 36 is sleeved inside the main frame outer sleeve 35. An adjustment lock wire 37 is installed at the end of the main frame outer sleeve 35 for locking the main frame outer sleeve 35 and the main frame inner sleeve 36. A rolling washing mechanism 4 is fixed at the end of each main frame inner sleeve 36.

[0036] like Figure 6 As shown, the roller washing mechanism 4 includes a U-shaped housing 41, a wheel frame 42, a roller 43, a high-pressure nozzle 44, a water supply pipe 45 and a water pipe joint 46. The wheel frame 42 is provided in the middle of the inner wall of the U-shaped housing 41, and a roller 43 is installed in the wheel frame 42 (the roller and its rotating shaft are sleeved together through a bearing), and the outer surface contour of the roller 43 is consistent with the outer surface contour of the upper guardrail. High-pressure nozzles 44 are respectively installed on the left and right arms of the wheel frame 42, and an inner cavity is provided in the U-shaped housing 41, in which a water supply pipe 45 is installed, the outer end of the water supply pipe 45 is connected to the high-pressure nozzle 44, and the inner end of the water supply pipe 45 is installed with a water pipe joint 46, and the water pipe joint 46 is connected to the high-pressure water supply pipe. If an inner cavity is set at the central axis hole position of the wheel frame 42, and a water wheel is installed on the rotating shaft of the roller 43 (the roller and its rotating shaft are integrated), one end of the water supply pipe 45 is connected to the upper part of the inner cavity, and the other end is connected to the lower part of the inner cavity, then when high-pressure water flows in the water supply pipe 45, it can impact the blades of the water wheel, causing the water wheel to rotate.

[0037] like Figure 7 and Fig. 9As shown, the auxiliary clamping assembly 5 includes a lifting block 51, an auxiliary frame inner sleeve 52, an auxiliary frame outer sleeve 53, an auxiliary frame locking wire 54 and an auxiliary frame screw sleeve 55. A pair of auxiliary clamping assemblies 5 correspond to the middle railing and the lower railing respectively. An auxiliary frame screw sleeve 55 is vertically arranged in the middle of the lifting block 51, and guide holes 56 are arranged on the left and right sides of the auxiliary frame screw sleeve 55. The auxiliary frame screw sleeve 55 is sleeved on the outside of the screw rod 33, and the guide holes 56 are assembled on the outside of the guide rod 34. An auxiliary frame inner sleeve 52 is vertically fixed to the outer end of the lifting block 51, and an auxiliary frame outer sleeve 53 is sleeved on the outside of the auxiliary frame inner sleeve 52. An auxiliary frame locking wire 54 is installed at the connection position of the auxiliary frame inner sleeve 52 and the auxiliary frame outer sleeve 53. The auxiliary frame inner sleeve 52 and the auxiliary frame outer sleeve 53 can be relatively contracted and locked by the auxiliary frame locking wire 54.

[0038] The above scheme can simultaneously control the synchronous folding of the main clamping assembly 3 and the auxiliary clamping assembly 5 through the lifting motor 38. While controlling the expansion and folding of a pair of main clamping assemblies 3, the expansion and folding of a pair of auxiliary clamping assemblies 5 are also controlled by the same screw. According to the height of each railing of different types of guardrails, the height of each screw sleeve is adjusted. For example, a mounting hole is vertically arranged in the middle of the lifting block 51, and an auxiliary frame screw sleeve 55 is sleeved in the mounting hole. A radial locking wire is installed on one side of the mounting hole. By adjusting the height of the auxiliary frame screw sleeve 55 in the mounting hole, the height of the entire auxiliary clamping assembly 5 can be changed. After adjusting the height, the auxiliary frame screw sleeve 55 is fixed in the mounting hole by the radial locking wire.

[0039] A rolling washing mechanism 4 is installed at the outer end of the auxiliary frame outer sleeve 53. Fig. 9 As shown in (a), a reciprocating assembly 6 is installed between the upper and lower auxiliary clamping assemblies 5, and the reciprocating assembly 6 includes a vertical guide rod 61, a telescopic end 62, a vertical slider 63 and a sliding bearing 64. The vertical guide rod 61 is vertically fixed between the upper and lower auxiliary frame outer sleeves 53, or the telescopic end 62 is sleeved in the vertical guide rod 61. The lower end of the vertical guide rod 61 is fixed to the auxiliary frame outer sleeve 53 at the lower end. The upper end of the telescopic end 62 is fixed to the auxiliary frame outer sleeve 53 at the upper end. A through hole is vertically provided in the center of the vertical slider 63, and a sliding bearing 64 is sleeved in the through hole. The sliding bearing 64 is sleeved on the outer side of the vertical guide rod 61 and can slide up and down along the vertical guide rod 61. A limited top seat 60 is provided on the auxiliary frame outer sleeve 53 located at both ends of the vertical guide rod 61. When the vertical sliding block 63 slides along the vertical guide rod 61 to the upper and lower limit positions, it contacts the limited top seat 60. A manipulator assembly 7 is installed on the front side of the vertical sliding block 63. A high-pressure nozzle is provided on the manipulator assembly 7, and a walking mechanism is installed on the manipulator assembly 7. The upper and lower sliding limit positions of the vertical sliding block 63 are limited by the limited top seat 60 to avoid collision between the manipulator assembly 7 and the upper and lower rolling washing mechanisms 4.

[0040] like Fig.10As shown, a structure of a manipulator assembly 7 includes a horizontal axis 71, a rotating seat 72, a longitudinal control telescopic sleeve 73, a transverse control telescopic sleeve 74, a telescopic sleeve rod 75, a transverse control electromagnet 76, a thrust spring 77, a motor seat 78 and a rotary motor 79. At the outer end of the vertical slider 63, a rotating seat 72 is installed through the horizontal axis 71, a longitudinal control telescopic sleeve 73 is installed on the rotating seat 72, a transverse control telescopic sleeve 74 is fixed at the front end of the longitudinal control telescopic sleeve 73, a telescopic sleeve rod 75 is sleeved at both ends of the inner cavity of the transverse control telescopic sleeve 74, a transverse control electromagnet 76 is fixedly installed at the inner end of each telescopic sleeve rod 75, a thrust spring 77 is installed between the two transverse control electromagnets 76, a motor seat 78 is fixed at the outer end of each telescopic sleeve rod 75, and a rolling washing mechanism 4 is installed at the front end of the motor seat 78. A rotary motor 79 is installed at the rear end of the motor seat 78, and the rotating shaft of the rotary motor 79 is connected to the roller in the rolling washing mechanism 4. The longitudinal control telescopic sleeve 73 is in a fitting relationship as a whole, and includes an outer suit and an inner suit. The inner and outer suits are freely fitted together, but a longitudinal control electromagnet is installed at the root of the longitudinal control telescopic sleeve 73. Normally, the longitudinal control telescopic sleeve 73 is in a free telescopic state, but when the longitudinal control electromagnet is working, the longitudinal control telescopic sleeve 73 is in a contracted state, so that the entire manipulator assembly 7 can move horizontally to the next vertical railing.

[0041] When the above scheme is working, the running wheels of the vehicle body 1 move along the guardrail base, carrying the storage box 2, the main clamping assembly 3, the rolling washing mechanism 4, the auxiliary clamping assembly 5, the reciprocating assembly 6 and the manipulator assembly 7 and moving forward along the guardrail at a uniform and slow speed. Figure 7 and Figure 8As shown, first, when the sliding frame 22 extends from the fixed outer box 21, the main clamping assembly 3, the rolling washing mechanism 4, the auxiliary clamping assembly 5, the reciprocating assembly 6 and the manipulator assembly 7 are respectively located on the outside of the fixed outer box 21, and the lifting motor 38 is controlled by the controller to adjust the height of the main frame outer sleeve 35, so that the two rolling washing mechanisms 4 at the end of the main clamping assembly 3 can be buckled on the outside of the upper railing. The upper and lower auxiliary clamping assemblies 5 buckle the rolling washing mechanisms 4 at their ends on the upper side of the middle railing and the lower side of the lower railing respectively. When the controller controls the lifting motor 38 to rotate in the opposite direction, the above-mentioned pair of main clamping assemblies 3 and the pair of auxiliary clamping assemblies 5 are respectively in the unfolded state, so that the rolling washing mechanisms 4 at the ends of the main clamping assembly 3 and the auxiliary clamping assembly 5 are separated from the corresponding railings. When adjusting the reciprocating assembly 6 and the manipulator assembly 7, firstly, the rolling washing mechanism 4 at the end of the manipulator assembly 7 is sleeved on the bottom of the first vertical railing. When starting the work, the rotary motor 79 located on the manipulator assembly 7 is controlled by the controller to rotate, so that the rolling washing mechanism 4 at the end of the manipulator assembly 7 can move upward along the first railing and then return. At the same time, the controller controls the water supply system to provide high-pressure water to each high-pressure water supply pipe, so that each nozzle sprays high-pressure water outward respectively. The rolling washing mechanism 4 at the end of the two main clamping assemblies 3 can roll forward along the upper railing while performing high-pressure flushing on the periphery of the upper railing; the rolling washing mechanism 4 at the end of the two auxiliary clamping assemblies 5 rolls forward along the middle railing and the lower railing respectively, and sprays high-pressure water on the middle railing and the lower railing; the high-pressure nozzle at the end of the manipulator assembly 7 reciprocates and sprays high-pressure water on the vertical railing. After the manipulator assembly 7 performs a reciprocating operation of high-pressure water spraying on the first vertical guardrail, the controller controls the manipulator assembly 7 to expand and retract, and disengage from the clamping of the first guardrail. When the manipulator assembly 7 moves to the next vertical guardrail together with the vehicle body 1, the next vertical guardrail is reciprocated and cleaned according to the above steps. Each roller can be a roller brush.

[0042] A position sensor may also be installed outside the U-shaped housing 41 of the rolling washing mechanism 4. When the controller detects through the position sensor that the rolling washing mechanism 4 moves to the position of the guardrail post, the high-pressure nozzle 44 is controlled to spray water outward to perform high-pressure washing on the side of the guardrail post. The water outlet of the high-pressure nozzle 44 is a strip-shaped water knife 47.

[0043] On the basis of the above scheme, a distance-fixing mechanism can also be provided to allow the manipulator assembly 7 to release at a fixed distance, and the distance-fixing mechanism includes a middle slider 66, a pressure block 67, an adjustment wire 68 and a reset spring 69. Fig. 9As shown in (b), a groove is provided on the inner side of the transverse groove 65, and a middle slider 66 is installed in the groove. The lower end of the vertical guide rod 61 is fixed to the middle slider 66. A pressure block 67 is installed on the left and right sides of the groove of the transverse groove 65, and a return spring 69 is installed between the left and right pressure blocks 67 and the middle middle slider 66. Adjustment wires 68 are installed on the left and right end arms of the transverse groove 65, and the inner end thread of the adjustment wire 68 is connected with the screw hole of the pressure block 67. When the adjustment wire 68 is rotated, the pressure block 67 can be driven to move inward, thereby changing the initial position of the pressure block 67. When the vehicle body 1 moves forward, the storage box 2, the main clamping assembly 3 and the rolling washing mechanism 4 are driven to move forward as a whole. When approaching the next vertical guardrail for vertical reciprocating cleaning, the manipulator assembly 7 can remain in place but the return spring 69 is compressed to provide power storage. When the manipulator assembly 7 is released, it will instantly return to the next vertical guardrail under the action of the return spring 69. The reset distance is just the distance between the two vertical guardrails. By adjusting the adjusting wire 68, the spacing between the left and right pressing blocks 67 can be changed, thereby changing the reset distance.

[0044] Based on the above scheme, the specific implementation steps of using the road bridge guardrail cleaning device are as follows:

[0045] 1. Equipment preparation: Confirm that all components (such as the vehicle body, storage box, main clamping assembly, drum washing mechanism, auxiliary clamping assembly, reciprocating assembly, manipulator assembly, etc.) are installed properly and the water supply system is operating normally.

[0046] Connect the power supply and water supply system: Make sure the device is connected to a stable power supply, and connect the high-pressure water supply pipe to the water supply system to check whether the water pressure is normal.

[0047] 2. Start the equipment: Turn on the control system of the equipment and check the operating status of each part. Set the cleaning parameters (such as water pressure, cleaning speed, height of the rolling washing mechanism, etc.) according to the shape and degree of contamination of the guardrail.

[0048] 3. Start cleaning: Move the device to the guardrail starting position, making sure the device is aligned with the guardrail.

[0049] Main clamping assembly and auxiliary clamping assembly: The control system starts the lifting motor and the guide system, so that the main clamping assembly and the auxiliary clamping assembly clamp the upper rail, the middle rail and the lower rail respectively. The clamping assembly tightly fixes the guardrail to ensure that the equipment runs stably during the cleaning process and will not slide or detach due to the complex shape of the guardrail.

[0050] Roller washing mechanism: Start the roller washing mechanism, the roller rolls along the surface of the guardrail, and sprays high-pressure water through the high-pressure nozzle to fully clean the guardrail. The high-pressure water flow combined with the friction of the roller can effectively remove dust, mud and dirt on the surface of the guardrail, achieving efficient cleaning.

[0051] Cleaning the vertical railings: Start the manipulator assembly to clean the vertical railings with high-pressure water jets. The up and down and lateral movement of the manipulator assembly ensures that the vertical railings are fully covered and the cleaning effect is significant.

[0052] 4. Intelligent obstacle avoidance

[0053] When the equipment detects a guardrail post, the control system adjusts the sliding frame and track wheels to make the equipment avoid the post and continue to clean the adjacent part. The equipment intelligently avoids the guardrail post to avoid collision, improve the continuity of cleaning and the life of the equipment. When it is necessary to cross the guardrail post, the control system expands the main clamping assembly and the auxiliary clamping assembly, and shrinks the sliding frame a short distance, avoids the post and then returns to its original position. The equipment smoothly crosses the post to ensure that the cleaning process is continuous and uninterrupted.

[0054] 5. Keep cleaning

[0055] The equipment continues to move forward along the guardrail and repeats the above steps until the cleaning is completed. The equipment can automatically and continuously clean the guardrail, improve work efficiency and reduce manual intervention.

[0056] 6. Stop the device

[0057] After completing all cleaning tasks, turn off the water supply system and equipment power. Perform a comprehensive inspection of the equipment to ensure that all parts are in good condition and keep records.

[0058] According to the equipment maintenance manual, regularly maintain and inspect the equipment to ensure its long-term and stable operation.

[0059] Through the above steps, efficient, comprehensive and intelligent cleaning of road and bridge guardrails can be achieved, the cleaning efficiency and effect can be improved, the labor intensity can be reduced, and the safety and continuity of the cleaning operation can be ensured.
