Technical Field
[0001] The invention relates to the technical field of dam body crack processing equipment, and in particular to a water conservancy project concrete dam crack processing equipment and method. Background Art
[0002] Concrete dams are usually located in rivers or on the coast and are important infrastructure for water conservancy projects. During the hardening process of concrete dams, the concrete will shrink due to dehydration, or it will be affected by the temperature difference, causing uneven expansion and contraction and cracks. If the cracks are not treated after they occur, the cracks will continue to expand and cause greater defects in the dam body. Therefore, it is necessary to deal with the cracks accordingly in the early stage of their occurrence.
[0003] At present, the treatment method for concrete cracks is mostly pressure grouting, which is to plug the cracks by injecting a large amount of seam repair slurry (glue) into the cracks. However, during actual operation, the existing crack treatment equipment has poor uniformity in the cracks due to the slope of the earth dam. On the other hand, before repairing the cracks in the dam body, the operator needs to use external equipment to groove, clean, locate and then inject glue to seal the cracks. The whole process requires workers to frequently change operating tools, which is cumbersome and inconvenient. Summary of the invention
[0004] The invention discloses a crack treatment device and method for a concrete dam of a water conservancy project, aiming to solve the technical problems that, during actual operation, the existing crack treatment device is affected by the slope of the dam body, which affects the uniformity and effect of the repair in the gap; on the other hand, when repairing the cracks in the dam body, the whole process requires workers to frequently change operating tools, resulting in cumbersome and inconvenient operation.
[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A crack treatment device for a concrete dam of a water conservancy project, comprising a glue spray gun, a gripper is sleeved on the outer side of the glue spray gun, and a grinding mechanism for cleaning the cracks of the concrete dam is arranged at one end of the gripper; The other end of the grip is provided with a sealing mechanism for reducing the fluidity of the seam repair glue; The side of the grip is provided with a pneumatic mechanism for assisting cleaning and pressurizing the seam repair glue; The grinding mechanism is used to grind the gaps in the concrete dam and the pneumatic mechanism is used to clean it by pneumatic blowing. Then the sealing mechanism is used to seal the cracks after glue injection and the pneumatic mechanism is used to reinforce the cracks.
[0006] By providing a grip with a grinding mechanism on the basis of a glue spray gun, the user holds the grip and moves it slowly from top to bottom, and uses the grinding mechanism to grind the gap on the dam body. After grinding, the user continues to hold the grip and moves it from bottom to top, and uses the glue spray gun to inject seam glue into the gap. At the same time, the sealing mechanism provided can seal the glued part on the gap, thereby reducing the fluidity of the seam glue and ensuring the uniformity of the gap sealing. The pneumatic mechanism additionally provided on the side of the grip can, on the one hand, blow away the debris generated by grinding, and on the other hand, can use air pressure to impact the seam glue on the surface of the gap, so that the seam glue penetrates into the inside of the gap, so as to use one grip to integrate cleaning and removing impurities, spraying glue, sealing and improving the effect of seam repair, thereby greatly reducing the tediousness of traditional concrete dam repair and improving the convenience of repair.
[0007] In a preferred embodiment, the grinding mechanism includes a rotating shaft rotatably mounted on one end of the grip, a steel brush roller is fixedly sleeved on the outer side of the rotating shaft, the steel brush roller is in direct contact with the concrete dam, and a motor is horizontally mounted on the outer side of the grip, and the output end of the motor horizontally penetrates into the interior of the grip and is connected to the end of the rotating shaft.
[0008] A steel brush roller structure driven by a rotating shaft is arranged at the end of the grip, and a motor is used to drive the rotating shaft, which in turn drives the steel brush roller. The steel brush roller in contact with the gap of the concrete dam is used to grind the outer surface of the gap to remove impurities adhering to the outside of the gap. At the same time, the splashing impurities are guided by the shielding of the grip, thereby ensuring the efficiency of subsequent glue repair and the integrity of operation of the equipment.
[0009] In a preferred embodiment, the sealing mechanism includes a pin inserted into the other end of the grip, a sleeve is sleeved on the outer side of the pin, a cloth roll is wrapped around the outer side of the sleeve, the end of the cloth roll contacts the concrete dam, and a threaded groove is provided on the outer surface of the pin, and the threaded groove is threadedly connected to the inner surface of the grip.
[0010] A sleeve structure is provided which is rotatably mounted on the outside of the pin, and a cloth strip roll is additionally provided on the outside of the sleeve. When the grip is moved from bottom to top and the glue is sprayed, the cloth strip roll is simultaneously driven to rotate. The rotating cloth strip roll will unwind in sequence and adhere the cloth strips to the glue-coated area on the gap, so that the cloth strips are adhered to the outside of the gap by the seam repair glue, thereby reducing the fluidity of the seam repair glue in the gap, thereby improving the efficiency of the traditional glue repairing equipment during operation.
[0011] In a preferred embodiment, the pneumatic mechanism includes a blowing disk sleeved on the end of the rotating shaft, the blowing disk and the internal through-connection of the rotating shaft, a plurality of evenly distributed blowing holes are horizontally opened on the side of the blowing disk, the blowing holes are attached to the end of the steel brush roller, a first air row is horizontally installed at one end of the bottom of the grip, the first air row is horizontally distributed on the side of the steel brush roller, the bottom of the first air row is through-connected with a plurality of evenly distributed strip-shaped blowing pipes, a second air row is horizontally installed at the other end of the bottom of the grip, the second air row is horizontally distributed on the side of the cloth roll, the bottom of the second air row is through-connected with a plurality of evenly distributed cylindrical blowing pipes, a four-way connecting pipe is horizontally distributed on the side of the grip, the four-way connecting pipe is respectively through-connected to the ends of the first air row and the second air row, the four-way connecting pipe is rotatably connected to the end of the rotating shaft and is through-connected with each other.
[0012] By additionally arranging a pneumatic mechanism on the side of the grip, when the steel brush roller grinds the outer surface of the gap, the synchronously started air blowing plate can use the air blowing holes to blow from the side of the steel brush roller, so that the debris generated by grinding is blown toward the end away from the worker, and at the same time, the first air row with the strip-shaped air blowing pipe can introduce high-pressure gas into the interior of the gap, so as to blow the debris inside the gap outward, thereby ensuring the integrity of the operation of the steel brush roller; when the cloth strip roll seals the gap with infiltrated seam repair glue, the second air row with the cylindrical air blowing pipe is used to concentrate the high-pressure gas into the interior of the gap and the surface of the cloth strip roll, thereby pressurizing the seam repair glue and allowing the seam repair glue to penetrate into the interior of the gap, further improving the working efficiency and effect of traditional seam repair equipment.
[0013] In a preferred embodiment, an auxiliary component is provided at the bottom of the grip, and the auxiliary component includes an auxiliary roller distributed at one end of the bottom of the grip, and connecting parts are rotatably installed at both ends of the auxiliary roller. The top of the connecting part is fixedly connected with a spring and fixed to the bottom of the grip through the spring.
[0014] By providing an auxiliary roller structure connected to the bottom of the grip by a spring, when the user moves the grip from top to bottom, the user places the end of the cloth roll on the top of the auxiliary roller, and the auxiliary roller can isolate the contact between the cloth roll and the dam body, thereby ensuring the integrity of the operation of the equipment. When the cloth roll is applied to the outer surface of the gap, the auxiliary roller is pushed by the spring to squeeze the top of the cloth roll, which can assist the adhesion of the cloth roll, thereby ensuring the integrity of the operation of the equipment.
[0015] As can be seen from the above, the hydraulic engineering concrete dam crack treatment device and method provided by the present invention has the following improvements and advantages compared with the prior art: First, a convenient hand-held grip is added to the glue spray gun, and a steel brush roller structure driven by a rotating shaft is arranged at the end of the grip. The motor is used to drive the steel brush roller to grind the outer surface of the gap, and impurities adhered to the outside of the gap are removed, thereby ensuring the efficiency of subsequent glue repair and the integrity of the operation of the equipment. A threaded pin structure is provided at the other end of the grip, and the sleeve and cloth strip roll on the outside of the pin can be unwound synchronously by moving the grip from bottom to top, and the cloth strips are adhered to the glue coating on the gap in turn, so that the cloth strips are adhered to the outside of the gap by the seam repair glue, reducing the fluidity of the seam repair glue in the gap, and improving the efficiency of the traditional glue repair equipment during operation. The grinding and cleaning, seam repair and glue injection, and reinforcement and sealing are integrated together, thereby greatly reducing the tediousness of traditional concrete dam repairs and improving the convenience of repairs.
[0016] Secondly, an external pneumatic mechanism is additionally provided on the side of the grip. When the steel brush roller grinds the outer surface of the gap, the synchronously started air blowing plate can use the air blowing hole to blow from the side of the steel brush roller, so that the debris generated by grinding is blown toward the end away from the worker. At the same time, the first air row with the strip-shaped air blowing pipe can introduce high-pressure gas into the interior of the gap, so as to blow the debris inside the gap outward, ensuring the integrity of the operation of the steel brush roller; when the cloth strip roll seals the gap with infiltrated seam repair glue, the second air row with the cylindrical air blowing pipe is used to concentrate the high-pressure gas into the interior of the gap and the surface of the cloth strip roll, so as to pressurize the seam repair glue and allow the seam repair glue to penetrate into the interior of the gap, cooperate with the operation of the entire equipment, and further improve the working efficiency and effect of traditional seam repair equipment.

During the movement, the glue gun 1 will fill the seam repair glue into the inside of the crack, and the sealing mechanism 4 will seal the outer surface of the crack with a film to reduce the fluidity of the seam repair glue in the crack, and the pneumatic mechanism 5 will strongly blow on the outside of the crack seal, thereby pressurizing the seam repair glue inside the crack, causing the seam repair glue to penetrate deeper into the crack.
[0030] It should be additionally explained that: epoxy resin can be used as the repair glue, and a handle 7 is provided on the side of the grip 2 for the convenience of the operator to hold it.
[0031] In the above scheme, in order to reduce the influence of impurities located outside the gap on the flow of the seam sealing glue when the concrete dam is sealed, the specific operation is as follows.

[0034] In the above scheme, considering the influence of the slope of the dam body, the seam repair glue introduced into the gap of the concrete dam will slide down due to its own gravity. In order not to affect the uniformity and effect of the repair in the gap, the specific operation is as follows.
[0035] Reference Figures 1 to 3 , Figure 6In a preferred embodiment, the sealing mechanism 4 includes a pin 401 inserted into the other end of the grip 2, a sleeve 402 is sleeved on the outer side of the pin 401, a cloth roll 403 is wrapped around the outer side of the sleeve 402, the end of the cloth roll 403 contacts the concrete dam, and a thread groove 404 is provided on the outer surface of the pin 401, and the thread groove 404 is threadedly connected to the inner surface of the grip 2.
[0036] In this embodiment: after the concrete cracks are cleaned, the operator holds the grip 2 and fits the grip 2 to the bottom of the concrete dam crack, and starts the glue gun 1. The operator holds the grip 2 and slowly moves upward along the bottom of the crack. During the movement, the glue gun 1 will fill the seam repair glue into the inside of the crack, and the sleeve 402 and the cloth roll 403 located on the outside of the pin 401 will rub the outside of the concrete dam and rotate synchronously.

When replacing the sleeve 402, the user only needs to pinch the twist cap 405 and rotate the pin 401. The pin 401 will be screwed out from the inside of the grip 2 through the threaded groove 404, and the user can then replace the new sleeve 402.
[0037] In the above scheme, in order to improve the operation perfection of the equipment and the efficiency of seam repairing, the specific operations are as follows.

[0039] In this embodiment: the user connects the four-way connecting pipe 507 and the external air pump device. When the steel brush roller 302 grinds the outer surface of the crack, the air entering the blowing plate 501 through the four-way connecting pipe 507 will be blown out from the side of the steel brush roller 302 through the blowing hole 502, thereby blowing away the debris generated by grinding in a direction away from the worker. At the same time, the air entering the first air discharge 503 will be blown out through the strip blowing pipe 504, thereby blowing into the interior of the crack along the direction of the crack, blowing away the dirt inside the crack. When the rotating cloth strip roll 403 seals the outer surface of the crack that has infiltrated the mending glue, the gas entering the second air row 505 will be blown out through the cylindrical air blowing pipe 506 to pressurize the surface of the cloth strip adhered to the outside of the crack, thereby squeezing the mending glue and causing the mending glue to penetrate deeper into the crack; wherein, a plurality of air inlets 508 are evenly arranged inside the cloth strip roll 403, and the gas blown out through the cylindrical air blowing pipe 506 will intermittently enter the interior of the crack through the air inlet 508, thereby directly pressurizing the mending glue from the inside of the gap.
[0040] Further, it is supplemented that: debris discharge ports 304 are opened on both sides of one end of the grip 2, and the steel brush roller 302 is distributed between the two debris discharge ports 304. The dirt driven by the gas blown out by the blowing plate 501 will be discharged from the side of the grip 2 through the debris discharge ports 304.
[0041] In the above scheme, in order to improve the application effect of the cloth strip roll 403 on the outside of the gap, the specific operation is as follows.

The top of the connecting member 602 is fixedly connected with a spring 603 and fixed to the bottom of the grip 2 through the spring 603.
[0043] In this embodiment: when the operator holds the grip 2 and moves slowly downward along the top of the crack, the user passes the end of the cloth roll 403 through the top of the auxiliary roller 601, so that the cloth roll 403 does not contact the dam body, ensuring that the cloth roll 403 will not unwind; when the operator holds the grip 2 and moves slowly upward along the bottom of the crack, the user passes the end of the cloth roll 403 through the bottom of the auxiliary roller 601, so that the cloth roll 403 contacts the dam body. During the movement, the auxiliary roller 601 pushed by the spring 603 will rotate around the connecting piece 602 and squeeze the cloth roll 403, causing the cloth roll 403 to be squeezed and fit the gap.
[0044] Working principle: When in use, the user connects the end of the glue gun 1 to the external glue filling machine, and connects the four-way connecting pipe 507 to the external air pump device. At this time, the user holds the grip 2 and fits the grip 2 to the top of the crack in the concrete dam, starts the motor 303, and slowly moves downward along the top of the crack. During the movement, the motor 303 drives the rotating shaft 301 to rotate, and the rotating shaft 301 drives the steel brush roller 302 to rotate. The steel brush roller 302 grinds the outer surface of the crack, thereby grinding away impurities adhering to the outside of the gap. At this time, the gas entering the inside of the blowing plate 501 through the four-way connecting pipe 507 will be blown out from the side of the steel brush roller 302 through the blowing hole 502, thereby blowing away the debris generated by grinding in the direction away from the worker, and at the same time, the gas entering the inside of the first air row 503 will be blown out through the strip blowing pipe 504, thereby blowing into the inside of the gap along the direction of the crack. Blow away the dirt inside the gap; after completing the cleaning of the concrete crack, the operator now holds the grip 2 and fits the grip 2 to the bottom of the concrete dam crack, and starts the glue gun 1. The operator holds the grip 2 and slowly moves upward along the bottom of the crack. During the movement, the glue gun 1 will fill the seam glue into the inside of the crack, and the sleeve 402 and the cloth strip roll 403 located on the outside of the pin 401 will rub the outside of the concrete dam and rotate synchronously. The rotating cloth strip roll 403 will seal the outer surface of the crack that has infiltrated the seam glue, thereby reducing the fluidity of the seam glue in the crack. At the same time, the gas entering the second air exhaust 505 will be blown out through the cylindrical air blowing pipe 506 to pressurize the surface of the cloth strip adhered to the outside of the gap, and the gas will also intermittently enter the inside of the gap through the air inlet 508, thereby directly pressurizing the seam glue from the inside of the gap, causing the seam glue to penetrate deeper into the gap.

During the movement, the glue gun (1) fills the seam repair glue into the crack, and the sealing mechanism (4) seals the outer surface of the crack with a film to reduce the fluidity of the seam repair glue in the crack. The pneumatic mechanism (5) blows strongly on the outside of the crack seal to pressurize the seam repair glue inside the crack, causing the seam repair glue to penetrate deeper into the crack.
