Description

Technical Field

[0001] This invention belongs to the field of building technology and relates to a device and process for treating building cracks. Background Technology

[0002] Due to prolonged use and various factors, concrete buildings inevitably develop cracks. The traditional method for treating these cracks involves chiseling away the severely cracked sections and then reinforcing them with new concrete. This method is costly, time-consuming, and difficult to implement. In fact, most concrete cracks do not require complete removal and rebuilding. Instead, crack injection repair technology can completely repair them. This method is convenient, simple to operate, time-saving, material-saving, low-cost, has a short construction period, and is widely applicable.

[0003] Patent CN211597825U discloses a crack injection device. In use, the crack is first widened and dust is removed. The injection base is fixed on the crack, and the port of the fixed end is connected to the crack. The injection port is unscrewed, and the glue storage tube is injected. After the glue is injected, the injection port is tightened. By connecting the injection port and the connecting end, the glue storage cylinder is fixed to the injection base, and then the glue injection is performed.

[0004] The aforementioned processes, such as dust removal and crack widening, require manual labor through multiple steps, and involve using scrapers and files to remove dust from the floor, resulting in high labor intensity and low processing efficiency. Summary of the Invention

[0005] In order to reduce the labor intensity of workers when treating building cracks, this application provides a device and process for treating building cracks.

[0006] In a first aspect, this application provides a device for treating building cracks, employing the following technical solution: A device for treating building cracks, comprising: A movable seat, made of transparent material, capable of moving across the floors of a building; The motor is fixed to the upper surface of the movable base by a motor bracket; The slider is slidably disposed on the upper surface of the movable base, and the motor can drive the slider to reciprocate along the moving direction of the movable base through a transmission device. The scraper is located on the lower surface of the movable seat and near the front end of the movable seat. The fixed end of the scraper is fixedly connected to the slider, and the scraping end of the scraper can contact the floor surface of the building. A suction device includes a suction cylinder, a suction shaft, an impeller, and a suction pipe. The suction cylinder is fixed above a movable base. The impeller is located inside the suction chamber of the suction cylinder and is rotatably mounted on the suction cylinder via the suction shaft. A motor can drive the suction shaft to rotate via a transmission device. The suction pipe is located behind a scraper. The upper end of the suction pipe communicates with the suction chamber, and the lower end of the suction pipe can extend into a crack in the building floor.

[0007] By adopting the above technical solution, when cracks appear in the building floor, a movable base is placed on the floor, and the lower end of the suction pipe is inserted into the crack. Because the movable base is made of transparent material, it is easier for workers to align the suction pipe with the crack. Next, the worker pushes the movable base along the crack and starts the motor. The motor drives a slider to slide back and forth through a transmission device, causing the scraper to move back and forth, cleaning the dust around the crack. This reduces the risk of instability when fixing the glue injection base to the crack due to dust in subsequent processes. Simultaneously, the motor drives the suction shaft to rotate through a transmission device, causing the impeller on the suction shaft to rotate and sucking out the dust from the crack through the suction pipe, reducing the risk of unstable adhesion between the glue and the crack sidewalls due to dust in the subsequent glue application process. As the suction pipe travels through the crack, it comes into contact with the crack sidewalls, scraping off fine dust and widening the crack to some extent, while also reducing the risk of dust affecting the quality of subsequent glue application. In this solution, workers only need to push the mobile seat to move, which can simultaneously complete the dust removal around the crack, the dust suction inside the crack, and the crack widening process. The labor intensity is low and the processing efficiency is high.

[0008] Preferably, the processing equipment further includes a glue storage cylinder and a glue dispensing pipe. The glue storage cylinder is fixed above the movable seat. The glue storage cylinder has a piston inside. The outer ring of the piston slides and seals against the inner wall of the glue storage cylinder. The piston and the inner wall of the glue storage cylinder combine to form a glue storage cavity for storing sealant. The glue dispensing pipe is located behind the suction pipe. The upper end of the glue dispensing pipe is connected to the glue storage cavity. The lower end of the glue dispensing pipe can be close to the cracks in the building floor. The motor can drive the piston to move through the transmission device to change the volume of the glue storage cavity.

[0009] By adopting the above technical solution, when the mobile seat moves, the scraper at the front removes the dust, and the suction pipe behind the scraper sucks away the dust in the crack. The piston moves under the action of the motor and transmission device, reducing the volume of the glue storage chamber. The sealant in the glue storage chamber is squeezed into the crack of the building floor through the glue outlet pipe, forming a seal on the opening of the crack. This reduces the risk that the glue will flow out from the opening of the crack before it has flowed to the corners of the crack during subsequent glue injection, and allows the dehydration during glue injection to flow to the corners of the crack.

[0010] Preferably, the processing equipment further includes a glue-applying plate, which is located behind the glue-dispensing pipe. The fixed end of the glue-applying plate is fixedly connected to the slider, and the glue-applying end of the glue-applying plate can be close to the cracks in the building floor.

[0011] By adopting the above technical solution, when the motor is running, the dispensing tube squeezes the sealant to the cracks in the building floor. As the moving seat travels along the crack, the adhesive applicator behind it moves back and forth under the drive of the slider, which can smooth the sealant at the crack, increase the sealing area, and make the crack openings of different sizes better sealed.

[0012] Preferably, the glue injection base includes a coaxial bonding disc and a glue injection tube. The lower end of the glue injection tube is fixed at the center of the bonding disc. The bonding disc has a glue outlet hole communicating with the glue injection tube. The upper end of the glue injection tube can be connected to the glue outlet nozzle of the glue injector. The middle part of the movable base has a material discharge through hole coaxial with the suction pipe. The material discharge through hole penetrates the upper and lower surfaces of the movable base in a vertical direction. The inner diameter of the material discharge through hole is larger than the outer diameter of the bonding disc. The inner diameter of the glue injection tube is larger than the outer diameter of the suction pipe. The outer wall of the suction pipe is slidably sealed with the cylinder wall of the suction pipe. The movable base is provided with a drive device that can drive the suction pipe to rise and fall.

[0013] By adopting the above technical solution, the movable seat moves along the crack in the building floor, and the suction pipe moves synchronously in the crack. When the suction pipe can no longer move, it means that the crack has become too small. A crack that is too small will prevent the glue from flowing smoothly during the filling process. At this time, the suction pipe is lifted by the driving device, and the glue injection tube of the glue injection seat is placed on the lower end of the suction pipe. The driving device drives the suction pipe to fall, and the glue injection seat placed on the suction pipe falls to the crack under the guidance of the suction pipe, ensuring that the glue injection tube is aligned with the crack. This avoids the glue injection tube being offset relative to the crack, which would prevent the glue from being injected into the crack. At the same time, since the narrow part of the crack can be identified when the suction pipe cannot move, workers can set a glue injection seat at both narrow parts of the crack to prevent the glue from being unable to pass through the narrow part of the crack and affecting the filling quality.

[0014] Preferably, the processing equipment further includes a dispensing cylinder, the inner diameter of which is larger than the outer diameter of the adhesive tray of the glue injection seat. The dispensing cylinder is coaxial with the material discharge through hole. The outer wall of the dispensing cylinder is fixed to the inner wall of the material discharge through hole. A pipe is provided vertically on the side wall of the dispensing cylinder. The lower end of the pipe penetrates the lower end face of the dispensing cylinder. The lower end of the dispensing cylinder has a guide plate corresponding to the lower end of the pipe. The guide plate is inclined. The upper end of the guide plate is close to the outer side of the dispensing cylinder. The lower end of the guide plate extends toward the axis of the dispensing cylinder. The glue storage cylinder is connected to the upper end of the pipe through a second pipe. The dispensing pipe is equipped with an electric valve, and the second pipe is equipped with an electric valve.

[0015] By adopting the above technical solution, the movable seat moves along the crack. When the suction pipe encounters a narrow part of the crack and cannot move, the lifting device lifts the suction pipe, closes the electric valve one at the glue outlet pipe, and opens the electric valve two at the pipe two. The sealant enters the pipe one from the glue storage cylinder through the pipe two and flows towards the axis of the glue outlet cylinder through the guide plate, falling onto the building floor below the glue outlet cylinder. The glue injection seat falls onto the crack of the building floor through the glue outlet cylinder, and the adhesive plate of the glue injection seat is bonded to the building floor by the sealant to form a fixed position. Compared with the manual placement method, the glue injection seat fixing efficiency of this solution is higher, and under the guidance of the suction pipe, it is not easy to deviate when squeezing the sealant on the building floor, thus improving the fixing accuracy of the glue injection seat.

[0016] Preferably, the glue dispensing cylinder has an elastic retaining ring, the outer wall of which is fixed to the inner wall of the glue dispensing cylinder, the inner diameter of which is smaller than the outer diameter of the adhesive tray, and an annular push plate coaxial with the suction pipe is fixed to the outer wall of the suction pipe, the outer diameter of which is larger than the outer diameter of the glue dispensing pipe and smaller than the inner diameter of the elastic retaining ring.

[0017] By adopting the above technical solution, the bonding plate of the glue injection seat is placed above the elastic retaining ring. The lifting device drives the suction pipe to fall. The annular push plate on the outer wall of the suction pipe can contact the glue injection tube of the glue injection seat, pushing the glue injection seat to move down, causing the elastic retaining ring to deform. The glue injection seat falls onto the building floor through the glue dispensing cylinder.

[0018] Preferably, the transmission device includes a rotating shaft and a rotor. The rotating shaft is arranged vertically, with its upper end connected to the output end of the motor and its lower end coaxially connected to the rotor. The rotor has three drive teeth evenly spaced on its sidewalls. The slider has a square inner cavity with two opposite sidewalls having stepped surfaces. The rotor is located in the square inner cavity. When the rotor rotates, the drive teeth on the rotor can contact the stepped surfaces to push the slider to reciprocate.

[0019] By adopting the above technical solution, the motor rotates, and the rotor is driven to rotate through the rotating shaft, so that the drive teeth contact the stepped surface of the square inner cavity, pushing the slider to move back and forth, and causing the scraper and glue-applying plate connected to the slider to move back and forth.

[0020] Preferably, the transmission device two includes a driving pulley, a driven pulley, and a transmission belt. The driving pulley is coaxially fixed on the rotating shaft, and the driven pulley is coaxially fixed on the suction shaft. The driving pulley is connected to the driven pulley via the transmission belt.

[0021] By adopting the above technical solution, the motor drives the rotating shaft to rotate, and the rotating shaft drives the driven pulley to rotate through the active pulley and the transmission belt, so that the suction shaft rotates and the impeller rotates to draw air.

[0022] Preferably, the transmission device three includes a second driving pulley, a second driven pulley, a second transmission belt, and a lead screw. The second driving pulley is coaxially fixed to the suction shaft. The second driven pulley is rotatably disposed on the upper end face of the glue storage cylinder. The second driving pulley is connected to the second driven pulley via the second transmission belt. A threaded hole is provided at the center of the second driven pulley. The lower end of the lead screw passes through the threaded hole and is connected to the piston. The side wall of the lead screw is threadedly connected to the threaded hole. A guide shaft is also provided inside the glue storage cylinder. The guide shaft is arranged in a vertical direction. The upper end of the guide shaft is fixed to the top of the glue storage cylinder. The piston is eccentrically provided with a guide through hole in a vertical direction. The lower end of the guide shaft passes through the guide through hole and extends toward the lower end of the glue storage cylinder.

[0023] By adopting the above technical solution, the suction shaft rotates to drive the second active pulley to rotate, and the second active pulley drives the second driven pulley to rotate through the second transmission belt. The screw moves vertically under the combined action of the second driven pulley and the guide shaft, driving the piston to move inside the glue storage cylinder and changing the volume of the glue storage chamber.

[0024] Secondly, this application provides a process for treating building cracks, employing the following technical solution: A process for treating building cracks, using the aforementioned building crack treatment equipment, includes the following steps: S1: Place the movable seat at the beginning of the building crack and align the suction pipe with the building crack. S2: The lower end of the suction pipe is driven by the drive device to extend into the crack; S3: Propel the moving seat along the crack; Start the motor, and the motor drives the slider to move through the transmission device. The scraper connected to the slider cleans the dust around the crack. The motor drives the suction shaft to rotate through the transmission device 2, causing the impeller on the suction shaft to rotate, and the suction pipe sucks up the dust from the cleaned cracks; The motor drives the piston to move through the transmission device three, reducing the volume of the glue storage chamber, opening the electric valve one on the glue outlet pipe, and closing the electric valve two on the pipe two, so that the sealant in the glue storage chamber falls around the opening of the crack through the glue outlet pipe. The adhesive applicator connected to the slider moves back and forth to spread the sealant evenly around the opening of the crack. S4: When the suction pipe encounters a narrow crack and cannot proceed, the moving seat stops moving; S5: The drive unit drives the suction pipe to rise, placing the glue injection seat on the elastic retaining ring of the glue dispensing cylinder; S6: Close the electric valve one of the dispensing hose and open the electric valve two of the pipeline two. The sealant flows through the pipeline two and the pipeline one to the bottom of the dispensing hose. S7: The drive unit drives the suction pipe to descend, and the suction pipe pushes the glue injection seat down through the annular push plate, so that it falls on the sealant at the crack opening; S8: The drive unit drives the suction pipe to rise, and after the moving seat continues to travel along the crack, the drive unit drives the suction pipe to descend into the crack again. S9: Repeat steps S2-28 in sequence until all cracks in the building floor are covered with sealant and injection bases are installed. S10: After the sealant dries, connect the nozzle of the sealant applicator to the injection tube of the sealant base, and inject the sealant into the crack to fill the crack in the building floor.

[0031] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0032] like Figure 1 As shown, the equipment for treating cracks in this building includes a movable base 1, which is made of a transparent material, such as tempered glass.

[0033] In this embodiment, the movable seat 1 is preferably a rectangular plate, and the corners of the lower surface of the movable seat 1 are provided with wheels so that the movable seat 1 can move on the floor of the building.

[0034] like Figure 1 As shown, the equipment for treating cracks in this building includes a motor 2 and a slider 3. The motor 2 is fixed to the upper surface of the movable base 1 by a motor bracket 21, and the slider 3 is slidably disposed on the upper surface of the movable base 1.

[0035] In this embodiment, the motor bracket 21 includes two vertical arms 211 and a horizontal plate 212. The two vertical arms 211 are spaced apart along the width direction of the movable seat 1, and the lower ends of the two vertical arms 211 are fixed to the upper surface of the movable seat 1. The horizontal plate 212 is arranged in the horizontal direction, and the end of the horizontal plate 212 is fixed to the upper end of the vertical arms 211. The motor 2 is fixed to the middle of the horizontal plate 212.

[0036] The lower surface of slider 3 is in contact with the upper surface of movable seat 1, and the side wall of slider 3 is in contact with the vertical arm 211. The vertical arm 211 limits slider 3, so that slider 3 can only move along the length direction of movable seat 1, or it can be understood as moving along the moving direction of movable seat 1.

[0037] like Figure 2 , Figure 3 As shown, a transmission device 34 is provided between the motor 2 and the slider 3. The motor 2 can drive the slider 3 to slide back and forth along the moving direction of the moving seat 1 through the transmission device 34.

[0038] In this embodiment, the transmission device 34 includes a rotating shaft 341 and a rotor 342. The rotating shaft 341 is arranged vertically, and its upper end is connected to the output end of the motor 2. The lower end of the rotating shaft 341 is coaxially connected to the rotor 342. The side wall of the rotor 342 is evenly spaced with three driving teeth 3421. The slider 3 has a square inner cavity 312. The two opposite side walls of the square inner cavity 312 have stepped surfaces 313. The rotor 342 is located in the square inner cavity 312. When the motor 2 rotates, it drives the rotor 342 to rotate. The driving teeth 3421 on the rotor 342 can push the slider 3 to move back and forth by contacting the stepped surfaces 313.

[0039] To avoid interference, a strip-shaped clearance through hole 311 is provided on the upper surface of the slider 3 along the length of the moving base 1. The lower end of the rotating shaft 341 extends through the strip-shaped clearance through hole 311 into the square inner cavity 312 of the slider 3 and connects with the rotor 342. When the slider 3 moves, the presence of the strip-shaped clearance through hole 311 will prevent interference between the slider 3 and the rotating shaft 341, allowing the slider 3 to move smoothly.

[0040] like Figure 1 , Figure 2 As shown, the equipment for treating building cracks also includes a scraper 41. The scraper 41 is located on the lower surface of the movable base 1 and close to the front end of the movable base 1. The fixed end of the scraper 41 is fixedly connected to the slider 3, and the scraping end of the scraper 41 can contact the floor of the building.

[0041] In this embodiment, a strip-shaped through hole 11 is provided on the front end of the movable seat 1 along the length direction of the movable seat 1. The strip-shaped through hole 11 penetrates the upper and lower surfaces of the movable seat 1. The slider 3 includes a block 31 and a connecting rod 32. The block 31 is slidably disposed on the upper surface of the movable seat 1. One end of the connecting rod 32 is connected to the block 31, and the other end of the connecting rod 32 passes through the strip-shaped through hole 11 and is connected to the fixed end of the scraper 41.

[0042] When the block 31 moves, the connecting rod 32 can slide along the length of the strip-shaped through hole 11 and drive the scraper 41 to move back and forth along the moving direction of the moving seat 1 to scrape away the dust around the cracks in the building floor.

[0043] like Figure 1 , Figure 2 As shown, the equipment for treating cracks in this building also includes a suction device 5.

[0044] In this embodiment, the suction device 5 includes a suction cylinder 51, a suction shaft 52, an impeller 53, and a suction pipe 54. The suction cylinder 51 is fixed above the movable base 1 by a vertical rod. The impeller 53 is located inside the suction chamber 55 of the suction cylinder 51, and the impeller 53 is rotatably mounted on the suction cylinder 51 by the suction shaft 52. The suction shaft 52 is distributed in a vertical direction. The lower end of the suction shaft 52 is connected to the impeller 53, and the upper end of the suction shaft 52 extends to the outside of the suction chamber 55. The motor 2 can drive the suction shaft 52 to rotate through the transmission device 2 56. The suction pipe 54 is located behind the scraper 41. The upper end of the suction pipe 54 is connected to the suction chamber 55, and the lower end of the suction pipe 54 can extend into the cracks in the building floor.

[0045] In this embodiment, the transmission device 2 56 includes a driving pulley 561, a driven pulley 562, and a transmission belt 563. The driving pulley 561 is coaxially fixed on the rotating shaft 341, and the driven pulley 562 is coaxially fixed on the suction shaft 52. The driving pulley 561 is connected to the driven pulley 562 via the transmission belt 563. The motor 2 drives the rotating shaft 341 to rotate, and the rotating shaft 341 drives the driven pulley 562 to rotate via the driving pulley 561 and the transmission belt 563, causing the suction shaft 52 to rotate, and the impeller 53 to rotate and draw air.

[0046] As an alternative, the transmission device 2 56 can also be designed as a combination of a driving gear and a driven gear, with the driving gear coaxially fixed on the rotating shaft 341 and the driven gear coaxially fixed on the suction shaft 52, and the driving gear meshing with the driven gear.

[0047] like Figure 1 , Figure 2 As shown, the processing equipment also includes a glue storage cylinder 6 and a glue dispensing pipe 61. The glue storage cylinder 6 is fixed above the movable seat 1. The glue storage cylinder 6 has a piston 62 inside. The outer ring of the piston 62 slides and seals with the inner wall of the glue storage cylinder 6, and can slide vertically inside the glue storage cylinder 6. Alternatively, the glue storage cylinder 6 can be placed horizontally, and the piston 62 slides horizontally. Only the piston 62 and the inner wall of the glue storage cylinder 6 need to be combined to form a glue storage cavity 63 for storing sealant.

[0048] like Figure 1 , Figure 2 As shown, the dispensing pipe 61 is located behind the suction pipe 54. The upper end of the dispensing pipe 61 is connected to the glue storage chamber 63, and the lower end of the dispensing pipe 61 can be close to the cracks in the building floor. The motor 2 can drive the piston 62 to move through the transmission device 64 to change the volume of the glue storage chamber 63.

[0049] To facilitate the injection of sealant into the storage cavity 63, an inlet connector that can communicate with the storage cavity 63 can be provided on the side wall of the storage cylinder 6. The inlet connector is close to the upper end of the storage cylinder 6. In use, the piston 62 is raised to the upper end of the storage cylinder 6 to increase the volume of the storage cavity 63, so that the inlet connector communicates with the storage cavity 63, and then the sealant is injected into the storage cavity 63 through the inlet connector.

[0050] like Figure 2 , Figure 4As shown, in this embodiment, the transmission device 64 includes a driving pulley 641, a driven pulley 642, a transmission belt 643, and a lead screw 644. The driving pulley 641 is coaxially fixed to the suction shaft 52, and the driven pulley 642 is rotatably mounted on the upper end face of the glue storage cylinder 6. Specifically, a bearing 645 is provided at the upper end of the glue storage cylinder 6. The outer ring of the bearing 645 is fixed to the upper end face of the glue storage cylinder 6, and the upper end of the inner ring of the bearing 645 is fixed to the driven pulley 642. The driving pulley 641 is connected to the drive belt. Piston 643 is connected to driven pulley 642. Driven pulley 642 has a threaded hole at its center. The lower end of lead screw 644 passes through the threaded hole and is connected to piston 62. The side wall of lead screw 644 is threadedly connected to the threaded hole. A guide shaft 646 is also provided inside the glue storage cylinder 6. The guide shaft 646 is arranged in a vertical direction. The upper end of the guide shaft 646 is fixed to the top of the glue storage cylinder 6. Piston 62 has an eccentric guide hole in a vertical direction. The lower end of guide shaft 646 passes through the guide hole and extends toward the lower end of glue storage cylinder 6.

[0051] When the mobile seat 1 moves, the scraper 41 at the front scrapes away the dust, and the suction pipe 54 behind the scraper 41 sucks away the dust in the crack. The suction shaft 52 rotates, driving the second drive pulley 641 to rotate. The second drive pulley 641 drives the second driven pulley 642 to rotate through the transmission belt 643. The lead screw 644 moves vertically under the combined action of the second driven pulley 642 and the guide shaft 646, driving the piston 62 to move in the glue storage cylinder 6, reducing the volume of the glue storage chamber 63, and squeezing the sealant in the glue storage chamber 63 through the glue outlet pipe 61 to the crack in the building floor, forming a seal on the crack opening, reducing the risk that the glue will flow out from the crack opening before it reaches the corners of the crack during subsequent glue injection, so that the dehydration during glue injection can flow to the corners of the crack.

[0052] As an alternative, the transmission device 64 may also include a driving gear and a driven gear. The driving gear is coaxially fixed to the suction shaft 52, and the driven gear is rotatably mounted on the upper end of the glue storage cylinder 6. An internal thread is provided at the center of the driven gear to cooperate with the lead screw 644.

[0053] like Figure 1 , Figure 2 As shown, the processing equipment also includes a glue-applying plate 42, which is located behind the glue-dispensing pipe 61. The fixed end of the glue-applying plate 42 is fixedly connected to the slider 3, and the glue-applying end of the glue-applying plate 42 can approach the cracks in the building floor.

[0054] Specifically, a strip-shaped through hole 12 is provided on the plate surface at the rear end of the movable seat 1 along the length direction of the movable seat 1. The strip-shaped through hole 12 penetrates the upper and lower surfaces of the movable seat 1. The slider 3 also includes a connecting rod 33. One end of the connecting rod 33 is connected to the block 31, and the other end of the connecting rod 33 passes through the strip-shaped through hole 12 and is connected to the fixed end of the adhesive application plate 42.

[0055] When the motor 2 is running, the dispensing tube 61 squeezes the sealant to the cracks in the building floor. As the moving seat 1 moves along the crack, the adhesive spreading plate 42 behind it moves back and forth under the drive of the slider 3, which can smooth the sealant at the crack, increase the sealing area, and make the crack openings of different sizes better sealed.

[0056] like Figure 2 , Figure 5 As shown, the glue injection base 7 includes a coaxial bonding plate 71 and a glue injection tube 72. The lower end of the glue injection tube 72 is fixed to the center of the bonding plate 71. The bonding plate 71 has a glue outlet hole 711 that communicates with the glue injection tube 72. The upper end of the glue injection tube 72 can be connected to the glue outlet nozzle of the glue injector. The specific connection method can be a threaded connection, a plug-in connection, etc. The glue injector can be a piston type 62, similar to the structure of an injection cylinder. When the glue injection base 7 is bonded to the crack opening, the glue injector injects glue into the glue injection tube 72. The glue enters the crack through the glue injection tube 72 and the glue outlet hole 711.

[0057] like Figure 2 , Figure 5 As shown, the movable seat 1 has a material discharge through hole 13 coaxial with the suction pipe 54 in the middle. The material discharge through hole 13 penetrates the upper and lower surfaces of the movable seat 1 in the vertical direction. The inner diameter of the material discharge through hole 13 is larger than the outer diameter of the adhesive plate 71. The inner diameter of the glue injection pipe 72 is larger than the outer diameter of the suction pipe 54. The outer wall of the suction pipe 54 slides and seals with the cylinder wall of the suction cylinder 51. The movable seat 1 is equipped with a drive device that can drive the suction pipe 54 to rise and fall.

[0058] In this embodiment, the driving device includes a cylinder 8, which is arranged vertically. The cylinder body of the cylinder 8 is fixed to the outer wall of the suction pipe 51. The telescopic rod of the cylinder 8 is connected to the suction pipe 54 through a horizontal plate. The movement of the telescopic rod drives the suction pipe 54 to rise and fall.

[0059] Alternatively, a linear motor 2 can be used as the drive unit.

[0060] like Figure 2 , Figure 5 As shown, the processing equipment also includes a dispensing cylinder 9. The inner diameter of the dispensing cylinder 9 is larger than the outer diameter of the adhesive plate 71 of the dispensing seat 7. The dispensing cylinder 9 is coaxial with the material discharge through hole 13. The outer wall of the dispensing cylinder 9 is fixed to the inner wall of the material discharge through hole 13. A pipe 91 is provided on the side wall of the dispensing cylinder 9 in the vertical direction. The lower end of the pipe 91 passes through the lower end face of the dispensing cylinder 9. The lower end of the dispensing cylinder 9 has a guide plate 92 corresponding to the lower end of the pipe 91. The guide plate 92 is inclined. The upper end of the guide plate 92 is close to the outside of the dispensing cylinder 9. The lower end of the guide plate 92 extends toward the axis of the dispensing cylinder 9. The glue storage cylinder 6 is connected to the upper end of the pipe 91 through the second pipe 65. The dispensing pipe 61 is equipped with an electric valve 93, and the second pipe 65 is equipped with an electric valve 66.

[0061] Preferably, the upper end of the glue dispensing cylinder 9 is provided with an annular cavity 94, and there are multiple pipes 91 with a tapered longitudinal section. The upper end of the pipe 91 is the large-diameter end and is connected to the annular cavity 94. It is connected to the pipe 65 through the annular cavity 94. The lower end of the pipe 91 is the small-diameter end, so that the pressure on the glue when it approaches the lower end of the pipe 91 can be increased, and the glue can flow more accurately to the predetermined position under the action of the guide plate 92.

[0062] Preferably, the glue dispensing cylinder 9 has an elastic retaining ring 95, the outer wall of the elastic retaining ring 95 is fixed to the inner wall of the glue dispensing cylinder 9, the inner diameter of the elastic retaining ring 95 is smaller than the outer diameter of the adhesive plate 71, and an annular push plate 541 coaxial with the suction pipe 54 is fixed to the outer wall of the suction pipe 54, the outer diameter of the annular push plate 541 is larger than the outer diameter of the glue injection pipe 72 and smaller than the inner diameter of the elastic retaining ring 95.

[0063] The movable seat 1 moves along the crack in the building floor, and the suction pipe 54 moves synchronously in the crack. When the suction pipe 54 can no longer move, it means that the crack has become too small. A crack that is too small will prevent the glue from flowing smoothly during the injection. At this time, the suction pipe 54 is lifted by the drive device, and the adhesive plate 71 of the glue injection seat 7 is placed above the elastic ring. The electric valve 93 at the glue outlet pipe 61 is closed, and the electric valve 66 at the second pipe 65 is opened. The sealant enters the first pipe 91 from the glue storage cylinder 6 through the second pipe 65, and flows towards the axis of the glue outlet cylinder 9 through the guide plate 92, falling on the building floor below the glue outlet cylinder 9. The lifting device drives the suction pipe 54 to fall. The annular push plate 541 on the outer wall of the suction pipe 54 can contact the glue injection pipe 72 of the glue injection seat 7, pushing the glue injection seat 7 to move down, causing the elastic retaining ring 95 to deform. The glue injection seat 7 falls on the building floor through the glue outlet cylinder 9.

[0064] This embodiment also provides a process for treating building cracks, using the following technical solution: A process for treating building cracks, using the aforementioned building crack treatment equipment, includes the following steps: S1: Place the movable seat 1 at the beginning of the building crack, so that the suction pipe 54 is aligned with the building crack. S2: The lower end of the suction pipe 54 is driven to extend into the crack by the driving device; S3: Propel the movable seat 1 along the crack; Start motor 2, motor 2 drives slider 3 to move through transmission device 34, and scraper 41 connected to slider 3 cleans the dust around the crack; Motor 2 drives the suction shaft 52 to rotate through transmission device 2 56, causing the impeller 53 on the suction shaft 52 to rotate, and the suction pipe 54 sucks up the dust from the cleaned cracks; Motor 2 drives piston 62 to move through transmission device 3 64, reducing the volume of glue storage chamber 63, opening electric valve 1 93 on glue outlet pipe 61, and closing electric valve 2 66 on pipe 2 65, so that the sealant in glue storage chamber 63 falls around the opening of the crack through glue outlet pipe 61. The adhesive applicator 42, connected to the slider 3, moves back and forth to spread the sealant evenly around the opening of the crack. S4: When the suction pipe 54 encounters a narrow crack and cannot move, the movable seat 1 stops moving; S5: The drive device drives the suction pipe 54 to rise, placing the glue injection seat 7 on the elastic retaining ring 95 of the glue dispensing cylinder 9; S6: Close the electric valve 93 of the dispensing pipe 61 and open the electric valve 66 of the second pipe 65. The sealant flows through the second pipe 65 and the first pipe 91 to the bottom of the dispensing pipe 61. S7: The drive device drives the suction pipe 54 to descend, and the suction pipe 54 pushes the glue injection seat 7 to move down through the annular push plate 541, and falls on the sealant at the crack opening. S8: The drive device drives the suction pipe 54 to rise, and after the moving seat 1 continues to travel along the crack, the drive device drives the suction pipe 54 to descend into the crack again. S9: Repeat steps S2-28 in sequence until all cracks in the building floor are covered with sealant and the sealant injection seat 7 is installed; S10: After the sealant dries, connect the nozzle of the sealant applicator to the sealant tube 72 of the sealant base 7, and inject the sealant into the crack to fill the crack in the building floor.
