Description

Technical Field

[0002] A bridge anti-collision guardrail spraying maintenance trolley is a device for spraying and maintaining bridge guardrails, mainly used for maintaining bridge anti-collision guardrails, and is composed of components such as a bracket spraying device.

[0003] After retrieval, the patent document with the publication number CN114892513B discloses a highway bridge maintenance spraying device. The highway bridge maintenance spraying device includes: a moving bracket, a water tank, and a spraying mechanism. The water tank is arranged on the moving bracket; the spraying mechanism includes: a support frame, a lift, a spraying member, and an adjustment and positioning structure. The support frame is located on one side of the moving bracket and is used to cover the anti-collision wall of the bridge; the lift is connected to the support frame and installed on the moving bracket for adjusting the height of the support frame; the spraying member is arranged on the support frame for spraying the surface of the anti-collision wall; the adjustment and positioning structure is arranged between the spraying member and the support frame for adjusting the relative position between the spraying member and the support frame and adjusting the spraying direction of the spraying member. It can solve the problems in the prior art that it is inconvenient to spray the bridge comprehensively and the nozzle is inconvenient to be adjusted to the most effective spraying angle, which easily leads to incomplete spraying of the bridge and affects the work efficiency.

[0004] Based on the retrieval and the prior art, it is found that for the existing cement anti-collision guardrail maintenance devices, the more common one is a maintenance trolley (such as the device retrieved above).

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0021] The present invention provides a self - propelled intelligent bridge maintenance device through improvement. The technical solution of the present invention is: As Figures 1 to 8As shown in the figure, an embodiment of the present invention provides a self - propelled intelligent bridge maintenance device, which includes a support mechanism. The support mechanism includes a support frame 1. On both sides of the bottom of the support frame 1, moving plates 9 are provided. At the bottom of the support frame 1, a first centering mechanism is provided to make the two moving plates 9 perform centering movement. A cross - plate 11 is fixed to the bottom of the moving plate 9, and at the bottom of the side of the cross - plate 11 away from the moving plate 9, a plurality of side rods 13 are provided. The side rod 13 is composed of two coaxially arranged square columns and a second centering mechanism to make the two square columns perform centering movement. One end of a square column inside the side rod 13 is fixed to the bottom of the cross - plate 11. A synchronization mechanism is provided outside the cross - plate 11 to make each second centering mechanism work synchronously. Spraying mechanisms 12 are provided between both ends of the support frame 1 and between the two square columns inside the side rod 13. A cross - bar 19 is commonly fixed to the outside of the side rods 13 at the same height. On the side of the cross - bar 19 facing the support frame 1, a plurality of extension rods 20 are fixed. One end of the extension rod 20 is fixed with a universal wheel 21. A moving mechanism for movement is provided at the bottom of the support frame 1; From the above connection relationship, it can be seen that an adjustable support mechanism is provided. Both the width and height of the support mechanism can be adjusted independently, so that it can be adapted to two or more types of anti - collision guardrails, and the adjustment process is simple and fast, facilitating the rapid progress of the anti - collision guardrail.

[0022] Specifically, as shown in the attached Figure 3 figure, a controller 24 is fixed to the top of the support frame 1; For supplementary explanation of the controller 24: The controller 24 is a prior art, and its specific structure and working principle will not be elaborated in detail here.

[0023] Specifically, as shown in the attached Figure 2 figure and the attached Figure 3 figure, a water tank 17 is fixed to the top of the support frame 1. A water level sensor 18 electrically connected to the controller 24 is fixed to the top of the water tank 17, and the detection end of the water level sensor 18 is located inside the water tank 17; From the above connection relationship, it can be seen that the water tank 17 is used for storing water. The water level sensor 18 is a prior art, and its specific structure and working principle will not be elaborated in detail here. The water level sensor 18 is used for monitoring the water level; For supplementary explanation of the above: A buzzer is fixed to the outside of the support frame 1. When the water level in the water tank 17 is too low, the buzzer gives an alarm.

[0024] Specifically, as shown in the attached Figure 2 figure, a high - pressure water pump 16 and a shunt pipe 15 are fixed to the top of the support frame 1. The high - pressure water pump 16 is electrically connected to the controller 24. The water inlet end of the high - pressure water pump 16 is connected to the top of the water tank 17, and the water outlet end of the high - pressure water pump 16 is connected to the shunt pipe 15; From the above connection relationship, it can be known that: The water pump transports the water in the water tank 17 to the shunt pipe 15. After the shunt pipe 15 shunts the water, it is respectively sent into each spraying mechanism 12.

[0025] Specifically, in combination with the attached Figures 1 - 3 As shown, at the middle position of the top end of one end of the support frame 1, an extension plate 22 is fixed. One end of the extension plate 22 is fixed with a laser temperature sensor 23 that is electrically connected to the controller 24. From the above connection relationship, it can be known that: The laser temperature sensor 23 is a prior art, and its specific structure and working principle will not be elaborated in detail here. The laser temperature sensor 23 is used to monitor the temperature of the anti-collision guardrail.

[0026] Specifically, in combination with the attached Figure 1 As shown, the first centering mechanism includes a guiding structure. The guiding structure includes a plurality of guiding rods 10. Both ends of the plurality of guiding rods 10 are respectively fixed on both sides of the support frame 1. Both moving plates 9 are slidably sleeved on each guiding rod 10. The first centering mechanism further includes a second motor 25, a worm 3, a worm gear 4, and two first threaded rods 2. The thread rotation directions of the two first threaded rods 2 are opposite. The outer sides of the two first threaded rods 2 are threadedly installed with first internal threaded sleeves that are adapted to each other. The two first internal threaded sleeves are respectively fixed to the two moving plates 9. Both ends of the worm 3 are coaxially fixed to the two worm 3. First rotation holes are opened on both sides of the support frame 1. One end of each of the two first threaded rods 2 is rotatably installed in the two first rotation holes. The second motor 25 is fixed to the support frame 1. The output shaft of the second motor 25 is coaxially fixed to one of the first threaded rods 2. The second motor 25 is electrically connected to the controller 24. From the above connection relationship, it can be known that: The guiding structure is provided so that the moving plate 9 can only perform linear sliding at the bottom inside the support frame 1. The working process of the first centering mechanism is that the second motor 25 rotates the first threaded rod 2 through the output shaft, and the worm 3 rotates synchronously with the two first threaded rods 2. Since the thread rotation directions of the two first threaded rods 2 are opposite, the two moving plates 9 perform synchronous and reverse-direction movements.

[0027] Specifically, in combination with the attached Figure 1 As shown, the moving mechanism includes multiple pairs of first support plates 8. A belt pulley 7 is rotatably installed on each pair of first brackets. One of the pairs of first support plates 8 is fixed with a first motor 6 that is electrically connected to the controller 24, and the output shaft of the first motor 6 is coaxially fixed to the belt pulley 7 on the corresponding first support plate 8. From the above connection relationship, it can be known that: The first motor 6 drives the belt pulley 7 fixed to it through the output shaft. This belt pulley 7 serves as a driving wheel to drive the entire device to move along the anti-collision guardrail, and the remaining belt pulleys 7 are used for auxiliary movement.

[0028] Specifically, in combination with the attachedFigure 7 and the attached Figure 8 As shown, the spraying mechanism 12 includes an intermediate plate 45. A second rotating hole is formed in the middle position on the outer side of the intermediate plate 45. An intermediate cylinder 38 is rotatably installed in the second rotating hole. Fourth bevel gears 33 and sixth bevel gears 37 coaxially arranged with the intermediate cylinder 38 are respectively fixed at both ends of the intermediate cylinder 38. Second support plates 30 and third support plates 35 are fixed on both plate surfaces of the intermediate plate 45. Third rotating holes are formed on the outer sides of the two second support plates 30. A common intermediate round rod 31 is rotatably installed in the two third rotating holes. A third bevel gear 32 coaxially arranged with the intermediate round rod 31 is fixed on the outer side of the intermediate round rod 31. The third bevel gear 32 meshes with the fourth bevel gear 33. Fourth rotating holes are formed on the outer sides of the two third support plates 35. Rotating cylinders 46 are rotatably installed in the two fourth rotating holes. A fifth bevel gear 36 coaxially arranged with the rotating cylinder 46 is fixed on the outer side of one end of the rotating cylinder 46. The fifth bevel gears 36 on the two rotating cylinders 46 both mesh with the sixth bevel gear 37. A water inlet pipe 34 is movably arranged in the intermediate cylinder 38. A second water distribution pipe 41 is fixed in the rotating cylinder 46. The second water distribution pipe 41 is hook-shaped. Nozzles 40 communicating with each other are fixed at one end of the second water distribution pipe 41 and one end of the water inlet pipe 34. First water distribution pipes 39 communicating with each other are fixed on both sides of one end of the water inlet pipe 34. A rotary joint 42 is jointly fixed at one end of the first water distribution pipe 39 and one end of the second water distribution pipe 41. The center of the fan-shaped water source sprayed by the nozzle 40 is coaxial with the rotating cylinder 46. Each water inlet pipe 34 is communicated with the shunt pipe 15 through a hose; The above is supplemented and explained as follows: Here, the nozzle 40 is selected as a nozzle 40 with a spraying angle of at least 120 degrees; From the above connection relationship, it can be seen that when the intermediate round rod 31 rotates, the third bevel gear 32 on the intermediate round rod 31 rotates with the intermediate round rod 31. The third bevel gear 32 drives the rotating cylinder 46 through the fourth bevel gear 33 meshing with it. The rotating cylinder 46 drives the sixth bevel gear 37. The sixth bevel gear 37 toggles the two fifth bevel gears 36. The two fifth bevel gears 36 rotate in opposite directions, so that the three nozzles 40 are staggered from each other, thereby expanding the fan-shaped area sprayed by the nozzles 40.

[0029] Specifically, as shown in the attached Figure 1 , the attached Figure 7 and the attached Figure 8 As shown, fifth rotating holes are formed at both ends of the support frame 1. A common first round rod 5 is rotatably installed in the two fifth rotating holes. A worm gear 4 coaxially arranged with the first round rod 5 is fixed on the outer side of the first round rod 5. The worm gear 4 meshes with a worm 3. The intermediate plates 45 of the spraying mechanisms 12 at both ends of the support frame 1 are fixed to the support frame 1. The first round rod 5 is coaxially fixed with the intermediate round rod 31 of the spraying mechanism 12 on the support frame 1. The intermediate round rod 31 of the spraying mechanism 12 on the support frame 1 is parallel to the rotating cylinder 46; From the above connection relationship, it can be known that: when the width of the support mechanism is adjusted, the worm 3 rotates, the worm 3 drives the worm wheel 4, the worm wheel 4 drives the first round rod 5, and the first round rod 5 drives the middle round rod 31 of the spray mechanism 12 on the support frame 1 to rotate. Since the middle round rod 31 of the spray mechanism 12 on the support frame 1 is parallel to the rotating cylinder 46, the three fan nozzles 40 in the spray mechanism 12 on the support frame 1 are staggered with each other.

[0030] Specifically, in combination with Figure 2 -Attached Figure 8 As shown, the second centering mechanism includes two second threaded rods 14 with opposite thread rotation directions, the two square columns in the side rod 13 are provided with threaded holes, the two second threaded rods 14 are respectively installed in the two threaded holes through external threads, the second threaded rods 14 of the two square columns are respectively coaxially fixed with the middle round rod 31 of the spray mechanism 12 between the two square columns, the synchronization mechanism includes a plurality of recessed frames 26, the recessed frames 26 are buckled on the cross plate 11 and fixed to the cross plate 11, the top of the recessed frames 26 is provided with a sixth rotating hole, a cylinder with a square hole is rotatably installed in the sixth rotating hole, a square rod 43 is fixed inside the square hole, and the square rod 43 is slidably inserted into the sixth rotating hole. On the second threaded rod 14, both sides of the horizontal plate 11 are fixed with a fourth support plate 44, and the two fourth support plates 44 are rotatably mounted with a second round rod 29, and a plurality of second bevel gears 28 coaxially arranged therewith are fixed to the outer side of the second round rod 29, and a first bevel gear 27 coaxially arranged therewith is fixed to the top of the cylinder, and the plurality of first bevel gears 27 are meshed with the plurality of second bevel gears 28, and the middle plate 45 of the spray mechanism 12 between the two square columns extends outward up and down and is movably buckled on the square column, so that the spray mechanism 12 can no longer rotate between the two square columns, and the rotating cylinder in the spray mechanism 12 between the two square columns is perpendicular to the middle round rod 31; Through the above connection relationship, it can be known that: the second round rod 29 is moved, and each second bevel gear 28 on the second round rod 29 rotates, the second bevel gear 28 moves the first bevel gear 27 meshing with it, and the first bevel gear 27 drives the cylinder fixed thereto, and the square rod 43 driven by the cylinder rotates, and the square rod 43 drives the second threaded rod 14 to rotate, and the second threaded rod 14 and the middle round rod 31 of the spray mechanism 12 between the two square columns rotate synchronously, so that the three fan nozzles 40 in the spray mechanism 12 between the two square columns are staggered with each other. Since the two second threaded rods 14 have opposite thread rotation directions, the two square columns perform synchronous and opposite linear motion, and the second threaded rod 14 plugged into the square rod 43 and the square rod 43 slide relative to each other.

[0031] Supplementary explanation to the above: both the first motor 6 and the second motor 25 are servo motors.

[0032] Working principle: The working process of the spraying mechanism 12 is as follows: When the middle round rod 31 rotates, the third bevel gear 32 on the middle round rod 31 rotates with the middle round rod 31. The third bevel gear 32 drives the rotating cylinder 46 through the fourth bevel gear 33 meshing with it. The rotating cylinder 46 drives the sixth bevel gear 37, and the sixth bevel gear 37 toggles two fifth bevel gears 36. The two fifth bevel gears 36 rotate in opposite directions, so that the three fan-shaped nozzles 40 are staggered from each other, thus expanding the fan-shaped area sprayed by the fan-shaped nozzles 40; The working steps of the whole device are as follows: First step, fasten the whole device on the anti-collision guardrail. Second step, start the second motor 25. The second motor 25 drives the first threaded rod 2 to rotate through the output shaft. The worm 3 rotates synchronously with the two first threaded rods 2. Since the thread directions of the two first threaded rods 2 are opposite, the two moving plates 9 approach each other until the universal wheels 21 on the side rod 13 contact the anti-collision guardrail. During this process, the worm 3 rotates, the worm 3 toggles the worm wheel 4, the worm wheel 4 drives the first round rod 5, and the first round rod 5 drives the middle round rod 31 of the spraying mechanism 12 on the support frame 1 to rotate. Since the middle round rod 31 of the spraying mechanism 12 on the support frame 1 is parallel to the rotating cylinder 46, the three fan-shaped nozzles 40 in the spraying mechanism 12 on the support frame 1 are staggered from each other; Third step, toggle the second round rod 29, and the second bevel gears 28 on the second round rod 29 rotate. The second bevel gears 28 toggle the first bevel gears 27 meshing with them. The first bevel gears 27 drive the cylinders fixed to them, and the cylinders drive the square rods 43 to rotate. The square rods 43 drive the second threaded rods 14 to rotate. The second threaded rods 14 rotate synchronously with the middle round rod 31 of the spraying mechanism 12 between the two square columns. Thus, the three fan-shaped nozzles 40 in the spraying mechanism 12 between the two square columns are staggered from each other. Since the thread directions of the two second threaded rods 14 are opposite, the two square columns perform linear motions that are synchronous and opposite in direction, and the second threaded rods 14 inserted into the square rods 43 slide relative to the square rods 43; Fourth step, the first motor 6 drives the belt pulley 7 fixed to it through the output shaft. This belt pulley 7, as a driving pulley, drives the whole device to move along the anti-collision guardrail, and the other belt pulleys 7 are used for auxiliary movement; Fifth step, the laser temperature sensor 23 can detect the temperature of the anti-collision guardrail, and thus adjust the spraying amount according to the temperature of the anti-collision guardrail (adjust by changing the power of the high-pressure water pump 16).
