Description

Technical Field

[0001] The invention relates to the technical field of concrete crack repair, in particular to a device for repairing internal damage of concrete cracks. Background Art

[0002] The concrete crack internal damage repair device is a device that can accurately and efficiently repair concrete cracks to ensure the stability and safety of the structure. In the basic maintenance of power transmission and transformation equipment, this repair device has a wide range of application scenarios, including but not limited to foundation components with different crack widths, key parts that bear loads and stresses, and emergency situations that require rapid restoration of structural integrity.

[0003] The device for repairing internal damage of concrete cracks adopts an advanced structural design, and usually includes key components such as a motor, an output shaft, an inner rod and a spiral blade. The working principle is that after starting the motor, the inner rod and the spiral blade are driven to rotate by the output shaft, and the concrete repair agent is evenly pushed into the crack to repair the crack. By using this repair device, the durability and safety of the foundation of power transmission and transformation equipment can be significantly improved, and the potential risks and maintenance costs caused by cracks can be reduced.

[0004] However, in the actual use of the above-mentioned equipment, most of the repair nozzles may directly contact the concrete surface during work, and are easily damaged by collision, friction, etc., which shortens the service life of the repair nozzle and increases the equipment maintenance cost. In addition, most of the equipment cannot thoroughly clean the impurities inside and around the cracks, resulting in incomplete cleaning and affecting the subsequent repair effect.

[0021] 1. In order to effectively repair concrete cracks, the device for repairing internal damage of concrete cracks is provided with a repair component. The component cooperates with the stirring device in the storage barrel to fully stir the repair material. The round rod mud pump filters the repair paddle in the storage barrel through the funnel and the filter plate, and then transports it to the repair cylinder and the repair nozzle through the mud outlet pipe and the mud conveying trough of the vertical rod.

Multiple groups of long rollers assist the vacuum nozzle to move smoothly. The brush can clean the dust and debris inside and around the crack under the action of the straight spring rod, making the vacuuming more thorough. The cleaned impurities enter the ash storage box through the connecting pipe for storage, effectively removing the debris in the crack.

[0023] 3. In order to further improve the accuracy and efficiency of the repair of internal damage to concrete cracks, a support assembly is provided. The assembly cooperates with the articulated frame on the vertical rod to connect the thin rod, thick rod, connecting frame, mounting rod, wheels and other components through a clockwork spring to stably support the vertical rod. The electric slide rail, square slider, articulated rod, short cylinder, straight rod and clamping tube cooperate with the limit rod on the connecting frame to make the vertical rod more stable in the supported state. Construction workers do not need to hold the vertical rod for a long time, and can directly push the device to repair the cracks, which reduces labor intensity and makes the construction process easier and more convenient.

[0024] 4. In order to reduce the waste of repair materials, the device for repairing internal damage of concrete cracks is provided with an auxiliary component. The component cooperates with the control button to control the solenoid valve switch of the mud conveying trough in the vertical rod, accurately controls the outflow of the repair paddle, and at the same time, pressing down the vertical rod can raise the round roller and the plugging head, so that the repair paddle can flow out to repair the crack. The plugging head can also play a certain guiding role, so that the repair paddle can be accurately injected into the crack. At the same time, when an accident occurs and the solenoid valve fails, the repair nozzle is blocked by the plugging head to prevent the repair paddle from excessive outflow.

[0042] A device for repairing internal damage of concrete cracks comprises a frame 1, a universal wheel 2 is arranged at the bottom of the frame 1, and a push handle frame 3 is arranged at the top of the frame 1. An operator first pushes the frame 1 through the push handle frame 3, and moves the device to a concrete crack repairing operation site through the universal wheel 2.

[0043] In one embodiment of the present invention, a repair component 4 is provided on the frame 1, and the repair component 4 includes a support cylinder 41, one end of the support cylinder 41 is fixedly installed on the top of the frame 1, one end of a material storage barrel 42 is fixedly installed on the other end of the support cylinder 41, and a round cover 43 is clamped and installed on the other end of the material storage barrel 42, and a stirring device 44 is provided on the round cover 43, one end of a funnel 45 is fixedly installed on the bottom of the material storage barrel 42, and a filter plate 46 is fixedly installed on the funnel 45, and a mud pump 47 is fixedly installed on the top of the frame 1. The mud outlet end of the pump 47 is fixedly installed with one end of a slurry outlet pipe 48, and the other end of the slurry outlet pipe 48 is fixedly installed with one end of a vertical rod 49. A mud conveying groove 410 is opened inside the vertical rod 49, and a repair cylinder 411 is slidably installed inside the vertical rod 49. A repair nozzle 412 is fixedly installed at one end of the repair cylinder 411 away from the top of the vertical rod 49, and a mounting ring 413 is fixedly installed on the vertical rod 49. One end of a spiral spring rod 414 is fixedly installed on the mounting ring 413, and a connecting plate 415 is fixedly installed on the repair nozzle 412. The other end of the spring rod 414 is fixedly installed on the top of the connecting plate 415, and a sealing cylinder 416 is fixedly installed at the bottom of the connecting plate 415. One end of a short spring 417 is fixedly installed at the bottom of the connecting plate 415, and one end of a short rod 418 is fixedly installed at the other end of the short spring 417. One end of a hinge block 419 is fixedly installed at the other end of the short rod 418, and a ball 420 is rotatably installed at the other end of the hinge block 419. The spiral spring rod 414, the connecting plate 415, the sealing cylinder 416, the short spring 417, and the short rod 418, hinged blocks 419 and balls 420 are provided in multiple groups, the mud pump 47 is arranged on the inner side of the support cylinder 41, the stirring device 44 is composed of a motor, a stirring rod, stirring blades and a turbine, the other end of the funnel 45 is fixedly connected to the mud outlet end of the mud pump 47, the internal space between the slurry outlet pipe 48 and the mud conveying trough 410 is communicated, the repair cylinder 411 slides on the inner side of the mud conveying trough 410, the short spring 417 is arranged on the inner side of the sealing cylinder 416, and the short rod 418 slides on the inner side of the sealing cylinder 416.

[0044] When the present embodiment is used, the round cover 43 is first opened, and the material for repairing concrete cracks is poured into the storage barrel 42. Subsequently, the stirring device 44 is started, and the motor in the stirring device 44 starts to run, and its output shaft drives the stirring rod to rotate, and the stirring blades installed on the stirring rod rotate rapidly accordingly. Under the coordinated action of the turbine, the stirring blades stir the repair material in the storage barrel 42, so that various components are fully mixed to ensure the uniformity of the repair material. When the repair material is evenly stirred, the mud pump 47 is started, and the mud pump 47 generates suction to extract the stirred repair paddle through the funnel 45 connected to the bottom of the storage barrel 42. At the same time, the filter plate 46 on the funnel 45 isolates the larger particle impurities that may exist in the repair paddle to prevent these impurities from entering the subsequent conveying pipeline to avoid pipeline blockage. The repair paddle after filtration flows along the slurry outlet pipe 48, and the slurry outlet pipe 48 is connected to the vertical rod 4 9 is connected to the mud conveying trough 410, and the repair paddle enters the mud conveying trough 410 to prepare for the final repair operation. The repair paddle continues to move forward in the mud conveying trough 410, enters the repair cylinder 411, and finally reaches the repair nozzle 412. When the repair nozzle 412 is working, multiple groups of short springs 417 play a buffering and protective role. One end of the short spring 417 is fixed to the bottom of the connecting plate 415, and the other end pushes the short rod 418, so that the ball 420 is tightly fitted to the concrete surface under the action of the short spring 417, so that the repair nozzle 412 will not directly collide with the concrete surface during operation, thereby avoiding damage to the repair nozzle 412 due to collision, friction, etc., ensuring that the repair work can be carried out continuously and stably. The construction personnel use the control device to aim the repair nozzle 412 at the concrete crack and accurately inject the repair paddle into the crack to repair the concrete crack.

[0045] In one embodiment of the present invention, a cleaning assembly 5 is provided on the frame 1, and the cleaning assembly 5 includes a dust pump 51, a dust pump 51 is fixedly installed on the top of the frame 1, one end of a connecting pipe 52 is fixedly installed on the dust outlet end of the dust pump 51, one end of an ash storage box 53 is fixedly installed on the top of the frame 1, and a sealing cover 54 is fixedly installed on the other end of the ash storage box 53, one end of a dust suction pipe 55 is fixedly installed on the dust suction end of the dust pump 51, and the other end of the dust suction pipe 55 is fixedly installed on the top of the vertical rod 49, a dust suction groove 56 is opened on the inner side of the vertical rod 49, a dust suction cylinder 57 is fixedly installed on the inner side of the vertical rod 49, and one end of the dust suction cylinder 57 away from the top of the vertical rod 49 is fixedly installed with one end of a dust suction nozzle 58, and the dust suction nozzle 58 is fixedly installed on the dust suction end of the dust pump 51. A long roller 59 is rotatably mounted on the other end of the dust nozzle 58, one end of a mounting plate 510 is fixedly mounted on the vertical rod 49, one end of a straight spring rod 511 is fixedly mounted on the mounting plate 510, a brush 512 is fixedly mounted on the other end of the straight spring rod 511, multiple groups of long rollers 59 are provided, a dust suction pump 51 is arranged on the inner side of the support cylinder 41, the dust suction pipe 55 and the slurry discharge pipe 48 are wrapped with a rubber hose 8, so that the dust suction pipe 55 and the slurry discharge pipe 48 are protected by the rubber hose 8, the other end of the connecting pipe 52 is connected to the internal space between the ash storage box 53, the internal space between the dust suction pipe 55 and the dust suction groove 56 is connected, and the dust suction cylinder 57 is arranged on the inner side of the dust suction groove 56.

[0046] When the present embodiment is used, the dust suction pump 51 is started during the repair work, and the dust suction pump 51 starts to work and generates suction. The dust outlet end of the dust suction pump 51 is connected to the connecting pipe 52, and the dust suction end is connected to the dust suction pipe 55. The suction force is transmitted to the inside of the vertical rod 49 through the dust suction pipe 55. The dust suction pipe 55 is connected with the dust suction groove 56 opened on the inner side of the vertical rod 49. The suction force acts on the dust suction groove 56, and then is transmitted to the dust suction cylinder 57 fixed on the inner side of the dust suction groove 56. Under the action of the suction force, the dust suction nozzle 58 sucks in the surrounding air and inclusions, and at the same time cooperates with multiple groups of long rollers 59. The long rollers 59 play an auxiliary role in the movement of the dust suction nozzle 58. They can reduce the friction between the dust suction nozzle 58 and the concrete surface, so that the dust suction nozzle 58 can move more smoothly on the concrete surface, covering the cracks and the surrounding areas, ensuring the thoroughness of the cleaning work, and at the same time cooperates with the straight spring The rod 511 provides continuous pressure for the brush 512, so that the brush 512 is in close contact with the concrete surface. When the dust nozzle 58 moves, the brush 512 cleans the dust, debris and the like inside and around the crack, loosens the impurities originally attached to the concrete surface, so that the dust nozzle 58 can suck it in more thoroughly. The dust and impurities sucked in by the dust nozzle 58 enter the connecting pipe 52 through the dust suction groove 56 and the dust suction pipe 55. At the same time, the other end of the connecting pipe 52 is connected to the ash storage box 53. The impurities enter the ash storage box 53 along the connecting pipe 52 for storage. When the impurities in the ash storage box 53 accumulate to a certain extent, the sealing cover 54 can be opened to clean the impurities to ensure that the ash storage box 53 can continue to work normally. Through the work of the cleaning component 5, the debris in the crack is effectively removed, creating favorable conditions for the subsequent repair paddle to better combine with the crack.

[0047] In one embodiment of the present invention, a support assembly 6 is provided on the vertical rod 49, and the support assembly 6 includes an articulated frame 61, and the articulated frame 61 is fixedly installed on the vertical rod 49, and one end of a spring spring 62 is fixedly installed on the inner side of the articulated frame 61, and a thin rod 63 is fixedly installed on the other end of the spring spring 62, and one end of a thick rod 64 is fixedly installed on the thin rod 63, and one end of a connecting frame 65 is fixedly installed on the other end of the thick rod 64, and a mounting rod 66 is fixedly installed on the other end of the connecting frame 65, and a wheel 67 is rotatably installed on the mounting rod 66, and an electric slide rail 68 is fixedly installed on the mounting ring 413, and a sliding wheel 67 is slidably installed on the electric slide rail 68. A movable part, a square slider 69 is fixedly connected to the sliding part, a hinged rod 610 is fixedly installed on the square slider 69, a short cylinder 611 is rotatably installed on the hinged rod 610, one end of a straight rod 612 is fixedly installed on the short cylinder 611, a clamping cylinder 613 is fixedly installed on the other end of the straight rod 612, a limiting rod 614 is fixedly installed on the connecting frame 65, a thick rod 64, a connecting frame 65, a mounting rod 66, a wheel 67, an electric slide rail 68, a square slider 69, a hinged rod 610, a short cylinder 611, a straight rod 612 and a clamping cylinder 613 are arranged in multiple groups, and the limiting rod 614 is rotatably installed on the inner side of the multiple groups of clamping cylinders 613.

[0048] When the present embodiment is used, when carrying out the repair work, it is necessary to unfold the support assembly 6 first to provide stable support for the vertical rod 49. At the same time, the spring spring 62 on the inner side of the hinge frame 61 on the vertical rod 49 is in a compressed state. When the support structure needs to be unfolded, the square slider 69 is driven to move by the electric slide rail 68, thereby releasing the spring spring 62 to a certain extent. The spring spring 62 begins to release its elastic force, pushing the thin rod 63 connected thereto to rotate around the hinge frame 61. The rotation of the thin rod 63 drives the thick rod 64 to move, and the thick rod 64 further drives the connecting frame 65, the mounting rod 66 and other components to move. Finally, the wheel 67 rotatably installed on the mounting rod 66 contacts the ground, completing the initial unfolding of the support structure. When the wheel 67 contacts the ground, in order to make the support assembly 6 better adapt to different terrains and construction requirements, by starting the electric slide rail 68 on the mounting ring 413, the electric slide rail 68 starts to work, driving the sliding member thereon to slide, thereby driving the square slider 69 to move The movement of the square slider 69 will change the position and angle of the hinged rod 610. The short cylinder 611 is rotatably installed on the hinged rod 610, and the short cylinder 611 is connected to the straight rod 612. Therefore, the straight rod 612 will also change its state as the position and angle of the hinged rod 610 change. The clamp 613 fixed at the other end of the straight rod 612 will adjust its position as the straight rod 612 moves. After the support structure has been precisely adjusted, it needs to be further reinforced to ensure the stability of the support. Through the adjustment of the positions of each component by the electric slide rail 68, and the clamp cooperation between the limit rod 614 and the clamp 613, the support assembly 6 provides stable and reliable support for the vertical rod 49. Construction personnel do not need to hold the vertical rod 49 for a long time, and can directly push the device to move through the wheels 67, which greatly reduces the labor intensity and makes the construction process easier and more convenient. At the same time, the stable support also ensures the accurate position of the repair nozzle 412 during the repair process, effectively improving the accuracy and efficiency of the repair.

[0050] When the present embodiment is used, the construction personnel need to accurately control the outflow of the repair paddle during the repair work. The construction personnel can control the switch of the electromagnetic valve 79 in the mud delivery trough 410 inside the vertical rod 49 by operating the control button 77. When the control button 77 is pressed, the electromagnetic valve 79 opens, and the repair paddle flows from the mud delivery trough 410 under the pressure of the mud pump 47; the control button 77 is pressed again, the electromagnetic valve 79 is closed, and the repair paddle stops flowing out. In this way, the construction personnel can control the outflow of the repair paddle according to the actual conditions such as the size and depth of the crack, so as to avoid the waste of the repair paddle. At the same time, when the repair work is carried out, when the vertical rod 49 is pressed down, the repair nozzle 412 gradually approaches the concrete crack. At this time, the repair The plugging head 75 and the round roller 76 in the nozzle 412 first contact the concrete surface, so that the plugging head 75 rises, the repair nozzle 412 is opened, and the repair paddle flows out of the repair nozzle 412 to repair the cracks. At the same time, the plugging head 75 plays a certain guiding role in the repair process. It can make the repair paddle more concentratedly injected into the cracks, thereby improving the accuracy of the repair. When an unexpected situation occurs and the solenoid valve 79 fails and cannot be closed, the plugging head 75 can play a certain anti-leakage role. Since the plugging head 75 is closely matched with the inside of the repair nozzle 412, under the action of the long spring 73, the plugging head 75 is pushed to block the repair nozzle 412, so that the repair paddle will not flow out excessively, effectively preventing the waste of the repair paddle and ensuring the smooth progress of the repair work.
