Description

Technical Field

[0001] The present invention relates to the technical field of bridge reinforcement, and particularly to a reinforcement structure for cracks in road bridges. Background Art

[0002] Road bridges generally consist of several major parts such as roadbeds, road surfaces, bridges, tunnel projects, and traffic engineering facilities, which are used to better meet the appearance of vehicles. However, during long-term use, the increase in traffic volume and the transportation of heavy vehicles are likely to cause cracks on the bridge surface.

[0003] When cracks occur, workers need to fill the cracks with asphalt. However, during the formation of the cracks, a large amount of dust will accumulate inside, affecting the fixing effect of the cracks. At the same time, when workers repair the cracks, it is easy for the asphalt to overflow in the cracks, resulting in poor crack repair effect, uneven filling affecting the road surface flatness, and affecting the comfort of road use.

[0004] Therefore, a new type of reinforcement structure for cracks in road bridges can be adopted to solve the deficiencies of the prior art. Summary of the Invention

An auxiliary moving component is installed on the grinding wheel.

[0012] In the above-mentioned road and bridge crack reinforcement structure, the auxiliary moving component includes a fixed rod fixedly installed on the lower surface of the grinding wheel. Two retractable frames are fixedly installed on the fixed rod. Two rotating shafts are jointly fixedly installed between the two retractable frames. Guide wheels are rotatably installed on both of the two rotating shafts. Spring one is installed on both of the two retractable frames.

[0013] In the above-mentioned road and bridge crack reinforcement structure, the vibration mechanism includes universal rods respectively rotatably installed on two support frames. The upper ends of the two universal rods are both fixedly installed with a first gear meshing with the second gear. The lower ends of the two universal rods are both fixedly installed with eccentric wheels. Two fixed sleeves are fixedly communicated with the box body.

[0014] In the above-mentioned road and bridge crack reinforcement structure, the auxiliary vibration component includes two chucks rotatably installed in the fixed sleeve.

And the eccentric wheel is located inside the vibrating rod. A rubber pad is fixedly installed at the lower port of the vibrating rod. And the lower end of the universal rod is rotatably installed on the rubber pad.

[0015] In the above-mentioned road and bridge crack reinforcement structure, the dust suction mechanism includes two protective shells fixedly installed in the box body. Rotating shafts are rotatably installed on both of the two protective shells. Belt wheels are fixedly installed at one ends of the two rotating shafts located outside the protective shells. A transmission belt is jointly rotatably sleeved between the two belt wheels. And one end of one of the rotating shafts is fixedly connected with the driving end of the second motor.

[0018] Compared with the existing technology, the advantages of the present invention are as follows:

[0019] 1: When the road and bridge crack reinforcement structure reinforces the bridge, it has the advantage of pre-treating the cracks before reinforcement. Through the setting of the protective shell and the dust suction pipe, the dust in the cracks can be adsorbed. At the same time, under the blockage of the filter plate, the dust is collected into the storage box, which can effectively clean the dust in the cracks and improve the crack reinforcement effect.

[0020] 2: When the road and bridge crack reinforcement structure reinforces the bridge, it has the advantage of treating the side walls of the cracks to improve the grouting reinforcement effect. The grinding wheels are driven by multiple hydraulic rods to grind the two sides of the cracks, and at the same time, two guide wheels are used to assist the grinding wheels to rotate, improving the grinding speed and effect of the cracks, increasing the friction force on the crack surface, and improving the adhesion effect of the slurry in the cracks after grouting.

[0021] 3: When the road and bridge crack reinforcement structure reinforces the bridge, it has the advantage of improving the grouting density by vibration during crack grouting. Through the setting of the universal rod and the eccentric wheel, the deviation between the center point and the center of gravity can be used to realize the vibration of the vibrating rod, so that the bubbles in the slurry injected into the cracks burst, improving the density of the injected slurry, and thus improving the reinforcement effect.

[0022] In summary, during the process of repairing and reinforcing the cracks, the present invention uses eccentric vibration to eliminate the bubbles in the slurry, improving the density inside the slurry. At the same time, before repairing the cracks, the inside of the cracks is ground and dusted, which can clean the impurities in the cracks and increase the friction force on the crack surface, thereby improving the repair and reinforcement effect of the bridge cracks.

Specific embodiments

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Refer to Figure 1 - Figure 2, a road and bridge crack reinforcement structure, including a moving part, a box body 1, and a dust cleaning and pouring part, Figure 1 The square block below the device is a schematic diagram of the ground, and a lightning-shaped groove is opened on it. For better illustration, the lightning-shaped groove is a schematic diagram of a crack;

[0038] The moving part includes a push rod 3 fixedly arranged on the box body 1. A rubber sleeve can be fixedly arranged on the push rod 3, which can make it more convenient for personnel to push. At the same time, the push rod 3 can be a telescopic rod, and the length of the push rod 3 can be adjusted according to the height of the user, making it more convenient to use;

[0039] A plurality of moving components 2 are installed below the box body 1. The moving components 2 are composed of a shielding cover and moving wheels. Shielding covers are fixedly installed at the four corners of the lower surface of the box body 1. Cross bars are fixedly installed in a plurality of shielding covers, and moving wheels are rotatably installed on a plurality of cross bars. Pushing the push rod 3 can drive the box body 1 to move driven by a plurality of moving wheels.

[0040] Refer to Figure 5 、 Figure 7 , the moving part further includes a grinding and moving mechanism. A motor 1 4 is fixedly installed on the box body 1. A through hole is opened on the box body 1. A driving shaft is fixedly installed on the driving end of the motor 1 4, and the driving shaft rotates in the through hole. A one-way bearing 1 1 and a one-way bearing 17 are fixedly installed on the driving shaft. A gear 2 12 is fixedly installed on the outside of the one-way bearing 1 1, and a fixed disk 18 is fixedly installed on the outside of the one-way bearing 17. The rotation directions of the one-way bearing 1 1 and the one-way bearing 17 are opposite, enabling the gear 2 12 and the fixed disk 18 to rotate separately;

[0041] A plurality of hydraulic rods 19 are fixedly installed on the lower surface of the fixed disk 18. The driving ends of the plurality of hydraulic rods 19 are jointly fixedly installed with a grinding wheel 13. A sliding hole is opened on the grinding wheel 13, and the grinding wheel 13 is slidably sleeved outside the driving shaft through the sliding hole. By driving a plurality of hydraulic rods 19, the grinding wheel 13 can be driven to enter the crack to grind the two sides of the crack, increasing the friction force on both sides inside the crack and enabling the slurry to adhere better to the crack;

[0042] The lower surface of the grinding wheel 13 is fixedly installed with a fixed rod, and two retractable frames 32 are fixedly installed on the fixed rod. The retractable frames 32 are arranged at a certain angle, but less than 90 degrees. Two support rods are arranged on the retractable frames 32, and the two support rods have a certain elasticity to enable the mutual approach and separation between the two support rods. Rotating shafts are fixedly installed between the brackets at both ends of the retractable frames 32, and guide wheels 20 are rotatably installed on the two rotating shafts. When the hydraulic rod 19 drives the grinding wheel 13 to move downward into the crack, it can drive the retractable frames 32 to move downward into the crack at the same time, and can drive the two guide wheels 20 to rotate in a circular motion with the fixed rod as the center point following the rotation of the drive shaft. A first spring 21 is fixedly installed between the two brackets on the same retractable frame 32, which can drive the elastic distance adaptation adjustment between the support rods on the two retractable frames 32 under the elasticity of the two first springs 21 when the multiple guide wheels 20 rotate in the crack, realizing stable movement in the irregular crack, so that the grinding wheel 13 rotates more quickly when grinding the crack.

[0043] Refer to Figure 4 、 Figure 6 and Figure 8 - Figure 11 , two fixed sleeves 14 are fixedly communicated in the box body 1. Two second springs 27 are installed in each of the two fixed sleeves 14. The lower ends of the multiple second springs 27 are fixedly installed with chucks 26. Annular grooves are formed in the two fixed sleeves 14. The multiple chucks 26 are all semi-circular. The two chucks 26 in the same fixed sleeve 14 combine into a ring. The corresponding two chucks 26 are both snap-fitted and installed in the annular groove. Universal rods 25 are snap-fitted and rotatably installed between the corresponding two chucks 26. The upper ends of the two universal rods 25 are rotatably installed with support frames, and the two support frames are both fixedly installed in the box body 1 to provide support for the universal rods 25. The upper ends of the two universal rods 25 are fixedly installed with a first gear 10 meshing with the second gear 12. The lower ends of the two universal rods 25 both penetrate through the corresponding two chucks 26 and are fixedly installed with eccentric wheels 30. The lower ends of the two universal rods 25 are rotatably installed with rubber pads 31. A vibrating rod 28 is fixedly installed on the rubber pad 31. The vibrating rod 28 is hollow and the lower port is open. The vibrating rod 28 is fixed on the universal rod 25, and the eccentric wheel 30 is located inside the vibrating rod 28. The position of the universal joint on the universal rod 25 is above the vibrating rod 28;

[0044] Through the setting of the second spring 27, the rod body part of the universal rod 25 can be made of rubber material, and the chuck 26 is also made of rubber material, which can increase the friction force of the universal rod 25 rotating between the two chucks 26, and can drive the two chucks 26 to shake in the annular groove when the universal rod 25 vibrates, improving the degree of bending of the universal rod 25 when rotating (the diameter of the annular groove is larger than the outer diameter of the two chucks 26, but under the elastic force of the second spring 27, the corresponding two chucks 26 are tightly snap-fitted outside the universal rod 25);

[0045] When the eccentric wheel 30 is arranged and the second gear 12 drives the first gear 10 to rotate, the universal joint on the universal rod 25 drives the eccentric wheel 30 to rotate. Since the center of gravity of the eccentric wheel 30 is not at the connection with the universal rod 25, when the eccentric wheel 30 rotates, it can drive the vibrating rod 28 to vibrate under the condition of eccentric center of gravity. At the same time, the rubber pad 31 is adopted to reduce the noise generated when the universal rod 25 rotates. The setting of the universal rod 25 can drive the eccentric wheel 30 to rotate in a circular motion and at the same time can drive the eccentric wheel 30 to move in a conical arc, so as to better vibrate the vibrating rod 28.

[0046] Refer to Figure 3 、 Figure 4 and Figure 8 As shown in, a conveying pipe 15 is fixedly communicated between two fixing sleeves 14. A perfusion pipe 5 is fixedly communicated with the conveying pipe 15. A fixing hole is opened on the box body 1. The upper end of the perfusion pipe 5 is fixedly penetrated in the fixing hole, and a funnel-shaped liquid inlet hopper (not shown in the figure) can be arranged at the port of the perfusion pipe 5 outside the box body 1, which is convenient for perfusion of asphalt, mud, etc., and can store for a short time in the liquid inlet hopper, can supplement the asphalt, mud, etc. for subsequent repair, and can ensure the continuity during crack repair;

[0047] Two branch pipes 24 are fixedly communicated with the part of the perfusion pipe 5 inside the box body 1. The two branch pipes 24 are arranged in a "V" shape and symmetrically arranged on both sides of the perfusion pipe 5. The upper ends of the two branch pipes 24 are fixedly communicated with cylindrical protective shells 6. The two protective shells 6 are fixedly installed inside the box body 1. Dust suction pipes 29 are fixedly communicated between the two protective shells 6 and the corresponding fixing sleeves 14. Circular filter plates 22 are fixedly installed inside the two protective shells 6. Installation holes are opened on the two protective shells 6. Bearings are fixedly sleeved in the two installation holes. Rotating shafts 8 are fixedly sleeved in the two bearings. A plurality of fan blades 23 are fixedly installed on the parts of the two rotating shafts 8 inside the protective shells 6. Belt wheels are fixedly installed at one ends of the two rotating shafts 8 outside the protective shells 6. Transmission belts 9 are rotatably sleeved on the two belt wheels. A second motor 7 is fixedly installed inside the box body 1, and one end of one of the rotating shafts 8 is fixedly connected with the driving end of the second motor 7;

[0048] When the second motor 7 starts, it can drive the other rotating shaft 8 to rotate simultaneously through one of the rotating shafts 8 and the transmission belt 9. The rotation of the two rotating shafts 8 can drive the fan blades 23 in the two protective cases 6 to rotate simultaneously. When the fan blades 23 in the two protective cases 6 rotate, they can successively suck out the dust in the cracks through the dust suction pipes 29 and the fixed sleeves 14, suck the dust into the protective cases 6, and filter the dust through the filter plates 22. Square arc-shaped holes are opened on both of the two protective cases 6, and storage boxes 16 are snap-fitted and installed in the square arc-shaped holes on the two protective cases 6. Rubber rings are provided at the upper ports of the two storage boxes 16, which can increase the friction with the corresponding square arc-shaped holes. At the same time, the dust filtered by the filter plates 22 can fall into the corresponding storage boxes 16 under the action of gravity. When it is necessary to clean the collected dust, just remove the corresponding storage box 16, and then snap the storage box 16 into the corresponding square arc-shaped hole after cleaning. Square holes can be opened on the box body 1, and a protective door is rotatably installed in the square holes. The structure inside the box body 1 can be cleaned and observed by opening the protective door.

[0049] Refer to Figure 4 、 Figure 8 , when multiple fan blades 23 rotate, at the same time, the gas in the perfusion pipe 5 can be adsorbed through the two protective cases 6 and the corresponding branch pipes 24, so that the air flow in the perfusion pipe 5 flows downward, which can assist in providing a downward suction force for the slurry, asphalt, etc. in the perfusion pipe 5. At the same time, the "V" shape of the two branch pipes 24 can prevent asphalt from entering the corresponding protective cases 6 along the two branch pipes 24 when adsorbing asphalt, and improve the fluidity of asphalt;

[0050] Asphalt enters the two fixed sleeves 14 along both ends of the perfusion pipe 5 and the delivery pipe 15, and under the vibration of the vibrating rod 28, the bubbles in the slurry, asphalt, etc. in the fixed sleeves 14 are eliminated, improving the fixing effect of asphalt and slurry on the bridge;

[0051] A cover plate (not shown in the figure) is fixedly arranged above the pipe orifice at the connection of the two dust suction pipes 29 and the corresponding fixed sleeves 14, which can prevent slurry from being adsorbed into the dust suction pipes 29 during dust suction, ensuring the simultaneous progress of dust suction and slurry perfusion. Or the two dust suction pipes 29 are directly connected to the lower surface of the box body 1, and at the same time, the lower ends of the dust suction pipes 29 are set as pipe orifices with smaller diameters, which can increase the air pressure of the air flow flowing out, so that the dust in the cracks can be better removed.

[0052] The specific operation steps of this road and bridge crack reinforcement structure are as follows:

[0053] The driving device moves in the crack: Push the push rod 3 by hand to push the box body 1 to the crack that needs to be reinforced through the moving component 2. The driving end of the first driving motor 4 drives the driving shaft to rotate forward. The forward rotation of the driving shaft drives the fixed disk 18 to rotate through the second one-way bearing 17. The rotation of the fixed disk 18 drives the grinding wheel 13 to rotate through a plurality of hydraulic rods 19. The driving ends of the plurality of hydraulic rods 19 are extended to drive the grinding wheel 13 and the guide wheels 20 into the crack. The grinding wheel 13 rotates to grind both sides of the crack. While the grinding wheel 13 rotates, it drives the two guide wheels 20 to rotate in the crack through the two retractable frames 32 to assist the movement of the device. At the same time, under the elasticity of the two first springs 21, the two guide wheels 20 can be driven to move adaptively according to the shape of the crack;

[0054] Adsorb the dust in the crack: The driving end of the second driving motor 7 rotates, which can drive one of the rotating shafts 8 to rotate. Through the setting of the transmission belt 9, the other rotating shaft 8 can be driven to rotate simultaneously, thereby driving the two fan blades 23 to rotate simultaneously. The two fan blades 23 rotate to adsorb the dust on both sides in the crack through the two protective shells 6, the dust suction pipes 29 and the fixed sleeves 14 in sequence. The dust enters the protective shell 6 through the fixed sleeve 14 and the dust suction pipe 29 in sequence, and the dust in the inhaled gas is filtered under the filtration of the filter plate 22 and falls into the storage box 16 for collection;

[0055] Inject the slurry into the crack: Inject the slurry through the perfusion pipe 5. The slurry flows into the conveying pipe 15 under the action of gravity. At the same time, the two fan blades 23 rotate to respectively have a certain suction force on the air flow in the perfusion pipe 5 through the two branch pipes 24 to assist the flow of the slurry in the perfusion pipe 5. After the slurry enters the conveying pipe 15, it enters the fixed sleeve 14 through both ends of the conveying pipe 15 and enters the crack through the fixed sleeve 14;

[0056] Vibrate the bubbles in the slurry: The driving end of the first driving motor 4 rotates reversely to drive the driving shaft to rotate reversely. At this time, the first one-way bearing 11 rotates to drive the second gear 12 to rotate. The second gear 12 rotates to drive the two first gears 10 to rotate. The two first gears 10 rotate to drive the two universal rods 25 to rotate. The two universal rods 25 rotate to drive the eccentric wheel 30 and the vibrating rod 28 to rotate. When the eccentric wheel 30 rotates, due to the eccentricity of the center of gravity, it will drive the vibrating rod 28 to vibrate better, so that the bubbles in the slurry entering the fixed sleeve 14 will burst during vibration, improving the density of the filled slurry.

[0057] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
