DETAILED DESCRIPTION

[0031] The present invention is described in detail below, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] The present invention provides a self-propelled intelligent bridge maintenance device through improvement. The technical solution of the present invention is:

[0033] like Figures 1 to 8 As shown, an embodiment of the present invention provides a self-propelled intelligent bridge maintenance device, including a support mechanism, which includes a support frame 1, movable plates 9 are provided on both sides of the bottom of the support frame 1, and a first centering mechanism for centering the two movable plates 9 is provided at the bottom of the support frame 1, a transverse plate 11 is fixed to the bottom of the movable plate 9, and a plurality of side rods 13 are provided at the bottom of the transverse plate 11 away from the movable plate 9, the side rod 13 is composed of two coaxially arranged square columns and a second centering mechanism for centering the two square columns, one end of one square column in the side rod 13 is fixed to the bottom of the transverse plate 11, and a synchronization mechanism for making each second centering mechanism work synchronously is provided on the outer side of the transverse plate 11, a spray mechanism 12 is provided at both ends of the support frame 1 and between the two square columns in the side rod 13, a transverse rod 19 is fixed to the outer side of the side rods 13 at the same height, a plurality of extension rods 20 are fixed to the side of the transverse rod 19 facing the support frame 1, and a universal wheel 21 is fixed at one end of the extension rod 20, and a moving mechanism for moving is provided at the bottom of the support frame 1;

[0034] From the above connection relationship, it can be seen that an adjustable support mechanism is provided, and the width and height of the support mechanism can be adjusted separately, so that it can adapt to two or more anti-collision guardrails, and the adjustment process is simple and quick, which facilitates the rapid installation of the anti-collision guardrail.

[0035] Specifically, in conjunction with Figure 3 As shown, a controller 24 is fixed to the top of the support frame 1;

[0036] 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.

[0037] Specifically, in conjunction with Figure 2 and attached Figure 3 As shown, a water tank 17 is fixed on the top of the support frame 1, and a water level sensor 18 is fixed on the top of the water tank 17 to establish an electrical connection with the controller 24, and the detection end of the water level sensor 18 is located in the water tank 17;

[0038] From the above connection relationship, it can be seen that the water tank 17 is used to store water, and the water level sensor 18 is a prior art, and its specific structure and working principle are not described in detail here. The water level sensor 18 is used to monitor the water level;

[0039] Supplementary explanation for the above: A buzzer is fixed on the outside of the support frame 1, and when the water level in the water tank 17 is too low, the buzzer sounds an alarm.

[0040] Specifically, in conjunction with Figure 2 As shown, a high-pressure water pump 16 and a diverter 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 of the high-pressure water pump 16 is connected to the top of the water tank 17, and the water outlet of the high-pressure water pump 16 is connected to the diverter pipe 15.

[0041] It can be seen from the above connection relationship that the water pump transports the water in the water tank 17 to the diversion pipe 15, and the diversion pipe 15 divides the water and sends it into each spray mechanism 12 respectively.

[0042] Specifically, in conjunction with Figure 1-3 As shown, an extension plate 22 is fixed at the middle position of the top of one end of the support frame 1, and a laser temperature sensor 23 electrically connected to the controller 24 is fixed at one end of the extension plate 22;

[0043] It can be seen from the above connection relationship 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.

[0044] Specifically, in conjunction with Figure 1 As shown, the first centering mechanism includes a guide structure, which includes a plurality of guide rods 10, the two ends of the plurality of guide rods 10 are respectively fixed on both sides of the support frame 1, and the two movable plates 9 are slidably sleeved on each guide rod 10. The first centering mechanism also includes a second motor 25, a worm 3, a worm wheel 4 and two first threaded rods 2. The threads of the two first threaded rods 2 are opposite, and the outer sides of the two first threaded rods 2 are threadedly mounted with first internal threaded sleeves that match each other. The two first internal threaded sleeves are respectively fixed to the two movable plates 9, and the two ends of the worm 3 are coaxially fixed to the two worms 3. First rotating holes are provided on both sides of the support frame 1, and one end of the two first threaded rods 2 is rotatably mounted in the two first rotating holes. The second motor 25 is fixed to the support frame 1, and the output shaft of the second motor 25 is coaxially fixed to one of the first threaded rods 2. The second motor 25 establishes an electrical connection with the controller 24;

[0045] From the above connection relationship, it can be seen that: the setting of the guide structure is so that the moving plate 9 can only slide linearly at the bottom of 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 threads of the two first threaded rods 2 have opposite rotation directions, the two moving plates 9 move synchronously and in opposite directions.

[0046] Specifically, in conjunction with Figure 1As shown, the moving mechanism includes a plurality of pairs of first support plates 8, each pair of first support plates is rotatably mounted with a pulley 7, one pair of first support plates 8 is fixed with a first motor 6 electrically connected to the controller 24, and the output shaft of the first motor 6 is coaxially fixed with the pulley 7 on the first support plate 8;

[0047] From the above connection relationship, it can be seen that the first motor 6 drives the shaft wheel 7 fixed to it through the output shaft. The shaft wheel 7 serves as a driving wheel to drive the entire device to move along the anti-collision guardrail, and the remaining shaft wheels 7 are used for auxiliary movement.

[0048] Specifically, in conjunction with Figure 7 and attached Figure 8 As shown, the spray mechanism 12 includes an intermediate plate 45, a second rotating hole is opened at the middle position of the outer side of the intermediate plate 45, an intermediate cylinder 38 is rotatably installed in the second rotating hole, and the fourth bevel gear 33 and the sixth bevel gear 37 coaxially arranged therewith are fixed at both ends of the intermediate cylinder 38, a second support plate 30 and a third support plate 35 are fixed on the two plate surfaces of the intermediate plate 45, the outer sides of the two second support plates 30 are opened with a third rotating hole, and an intermediate round rod 31 is rotatably installed in the two third rotating holes, and a third bevel gear 32 coaxially arranged therewith is fixed on the outer side of the intermediate round rod 31, and the third bevel gear 32 is meshed with the fourth bevel gear 33, and the outer sides of the two third support plates 35 are opened with a fourth rotating hole, and the rotating cylinder 4 is rotatably installed in the two fourth rotating holes. 6. A fifth bevel gear 36 coaxially arranged therewith is fixed to the outside of one end of the rotating cylinder 46. The fifth bevel gears 36 on the two rotating cylinders 46 are meshed with the sixth bevel gear 37. A water inlet pipe 34 is movably arranged in the middle cylinder 38. A first water branch pipe 39 is fixed in the rotating cylinder 46. The first water branch pipe 39 is hook-shaped. A fan nozzle 40 connected thereto is fixed to one end of the first water branch pipe 39 and one end of the water inlet pipe 34. A second water branch pipe 41 connected thereto is fixed on both sides of one end of the water inlet pipe 34. A rotary joint 42 is fixed to one end of the first water branch pipe 39 and one end of the second water branch pipe 41. The center of the fan nozzle water source sprayed from the fan nozzle nozzle 40 is coaxial with the rotating cylinder 46. Each water inlet pipe 34 is connected to the diversion pipe 15 through a hose.

[0049] Supplementary explanation for the above: Here, the fan nozzle 40 is a fan nozzle 40 with a spraying angle of at least 120 degrees;

[0050] From the above connection relationship, it can be seen that 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, and the third bevel gear 32 drives the rotating cylinder 46 through the fourth bevel gear 33 meshing with it, and the rotating cylinder 46 drives the sixth bevel gear 37, and the sixth bevel gear 37 shifts the two fifth bevel gears 36, and the two fifth bevel gears 36 rotate in opposite directions, so that the three fan nozzles 40 are staggered with each other, thereby expanding the fan-shaped area sprayed by the fan nozzle 40.

[0051] Specifically, in conjunction with Figure 1 , Attachment Figure 7 and attached Figure 8 As shown, both ends of the support frame 1 are provided with a fifth rotating hole, and a first round rod 5 is installed in the two fifth rotating holes for rotating together. A worm gear 4 coaxially arranged therewith is fixed to the outside of the first round rod 5, and the worm gear 4 is engaged with the worm 3. The middle plates 45 of the spraying mechanism 12 on both ends of the support frame 1 are fixed to the support frame 1, and the first round rod 5 is coaxially fixed to the middle round rod 31 of the spraying mechanism 12 on the support frame 1, and the middle round rod 31 of the spraying mechanism 12 on the support frame 1 is parallel to the rotating cylinder 46;

[0052] From the above connection relationship, it can be seen 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.

[0053] Specifically, in conjunction with Figure 2 -Attached Figure 8As shown, the second centering mechanism includes two second threaded rods 14 with opposite thread rotation directions, and 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, and the recessed frames 26 are buckled on the cross plate 11 and fixed to the cross plate 11. The top of the recessed frame 26 is provided with a sixth rotating hole, and 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, a fourth support plate 44 is fixed on both sides of the horizontal plate 11, and the two fourth support plates 44 are jointly rotated to install a second round rod 29, and a plurality of second bevel gears 28 coaxially arranged therewith are fixed to the outside of the second round rod 29. 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. 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.

[0054] From the above connection relationship, it can be known that: when the second round rod 29 is moved, the second bevel gears 28 on the second round rod 29 rotate, 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 threaded directions, the two square columns perform synchronous and opposite linear motion, and the second threaded rod 14 and the square rod 43 connected to the square rod 43 slide relative to each other.

[0055] Supplementary explanation to the above: the first motor 6 and the second motor 25 are both servo motors.

[0056] Working principle:

[0057] The working process of the spray 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, and 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 shifts the two fifth bevel gears 36. The two fifth bevel gears 36 rotate in opposite directions, so that the three fan nozzles 40 are staggered with each other, thereby expanding the fan-shaped area sprayed by the fan nozzles 40.

[0058] The working steps of the entire device are:

[0059] The first step is to snap the entire device onto the crash barrier;

[0060] The second step is to start the second motor 25. 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 threads of the two first threaded rods 2 rotate in opposite directions, the two movable plates 9 approach each other until the universal wheel 21 on the side rod 13 contacts the anti-collision guardrail. During this process, the worm 3 rotates, the worm 3 shifts the worm gear 4, and the worm gear 4 drives the first round rod 5. 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.

[0061] The third step is to shift the second round rod 29, and each second bevel gear 28 on the second round rod 29 rotates. The second bevel gear 28 shifts 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. 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 slides relative to the square rod 43.

[0062] In the fourth step, the first motor 6 drives the shaft wheel 7 fixed to it through the output shaft. The shaft wheel 7 acts as a driving wheel to drive the entire device to move along the anti-collision guardrail, and the remaining shaft wheels 7 are used for auxiliary movement;

[0063] In the fifth step, the laser temperature sensor 23 can detect the temperature of the anti-collision guardrail, thereby adjusting the spraying amount according to the temperature of the anti-collision guardrail (adjusting by changing the power of the high-pressure water pump 16).

[0064] The above description is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
