Description

Technical Field

[0001] The present invention relates to the technical field of building joint grouting, and particularly to a joint grouting device for civil engineering building structures. Background Art

[0002] Ancient buildings refer to buildings with a certain historical age and cultural value, usually those with uniqueness and representativeness in terms of architectural style, structure, materials, craftsmanship, etc. Since the materials of ancient buildings are generally wooden and have been built for a long time, the surface of ancient buildings is prone to cracking V-shaped cracks. If the cracks are not repaired in time, it will greatly affect the overall appearance and bearing capacity of ancient buildings. Therefore, professional technicians are required to repair the V-shaped cracks in ancient buildings.

[0003] In the prior art, when repairing the V-shaped cracks in ancient buildings, generally, impurities and rotten wood in the V-shaped cracks need to be removed first using brushes and scrapers, etc., and then cement-lime mortar is injected into the V-shaped cracks to improve the bearing capacity of ancient buildings. Due to the relatively narrow V-shaped cracks in ancient buildings, it is impossible for manual cleaning to completely scrape off the rotten wood. After the subsequent cement contacts the rotten wood, the connection ability of the repaired cement will be reduced. When injecting cement mortar, since there are cavities in the wooden material and the cement has a large fluidity in a short time after injection, when the cement is injected, air is easily overflowed from the wooden material into the cement, generating more bubbles and reducing the overall performance of the cement. Summary of the Invention

[0011] Preferably, the grinding and feeding device includes a first fixing ring rotatably arranged on the second fixing body. A second limiting groove is formed at the lower end of the first fixing ring. Two symmetrically arranged multi-stage electric telescopic rods are fixedly connected in the second limiting groove. The telescopic end of the multi-stage electric telescopic rod is fixedly connected to a second fixing ring in sliding fit with the second limiting groove.

[0012] Preferably, a third motor is fixedly connected to the side surface of the second fixing body. A gear is fixedly connected to the transmission shaft end of the third motor. A toothed ring meshing with the gear is fixedly connected to the side surface of the first fixing ring.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Extend the two multi-stage electric telescopic rods so that the pressure sensors on the grinding sac on the side of the second fixing ring contact the uppermost end of the V-shaped crack. Then, according to the values of the pressure sensors, the first electric telescopic rod is extended and retracted and the first motor is started. The first motor drives the rotating shaft to rotate, and the rotating shaft cooperates to drive the first fixing body to move. The first fixing body drives the grinding injector to move, so that the grinding injector moves along the upper surface of the V-shaped crack, and at the same time, the trajectory of the V-shaped crack is recorded. Then, extend the multi-stage electric telescopic rods and start the second motor at the same time. By making the values of multiple pressure sensors the same, the side of the second fixing ring is controlled to be parallel to the side of the V-shaped crack. Then, start the third motor. The third motor drives the gear to rotate, and the gear drives the second fixing ring to rotate through the toothed ring. The second fixing ring drives the grinding sac on the side to rotate. Lift and start the air pump, and the inflated grinding sac grinds the side of the V-shaped crack. During the grinding, the multi-stage electric telescopic rods are extended and retracted, so as to smoothly grind the side of the V-shaped crack in the vertical direction. At the same time, move according to the trajectory on the surface of the V-shaped crack, and the thickness of the grinding can be controlled through the values of the pressure sensors, ensuring that the entire side of the V-shaped crack is smoothly ground. While removing the rotten wood on the side of the V-shaped crack, ensure the smoothness inside the V-shaped crack, and improve the connection strength between the cement and the wood when pouring cement later;

[0017] 2. Extend the second electric telescopic rod, and the second electric telescopic rod drives the limiting plate to extrude the cement in the main body cylinder. The cement moves to the discharge port through the conveying pipe. By contracting the multi-stage electric telescopic rods, the cement coming out of the discharge port can be evenly smeared on the side of the V-shaped crack. When the side of the V-shaped crack is completely smeared, wait for the cement to completely solidify, and then completely inject the cement into the V-shaped crack. When injecting the cement, since the cement on the side of the V-shaped crack has solidified, it can prevent the gas in the wooden building from overflowing into the cement inside the V-shaped crack, reduce the generation of cavities in the cement, and improve the connection strength after the cement solidifies.

[0039] An air pump 485 is fixedly connected to the lower end of the second fixing body 49. An air delivery pipe 486 is fixedly connected to the air outlet end of the air pump 485. A grinding bag 487 is arranged at a position close to the lower end on the side surface of the second fixing ring 484. The outer side surface of the grinding bag 487 is a frosted structure.

An outlet 489 is arranged at the lower end of the second fixing ring 484.

[0040] Specifically, the first electric telescopic rod 31 is extended and retracted and the first motor 35 is started according to the value of the pressure sensor 488, so that the grinding and feeding device 48 moves along the upper surface of the V-shaped crack, and the trajectory of the V-shaped crack is recorded at the same time. Then, the multi-stage electric telescopic rod 483 is extended, and the second motor 310 is started at the same time. The side surface of the second fixing ring 484 is controlled to be parallel to the side surface of the V-shaped crack by the same values of a plurality of pressure sensors 488.

[0041] In this embodiment, a rolling mechanism 2 for moving the device is fixedly connected to the lower end of the main body cylinder 1.

[0042] Two symmetrically arranged support plates 21 are fixedly connected to the lower end of the main body cylinder 1. Hinge seats 22 are respectively fixedly connected to the lower sides of the two support plates 21 near both ends. Four roller wheels 23 are respectively rotatably arranged in the four hinge seats 22.

[0043] Specifically, move the device above the V-shaped crack through the roller 23. The roller 23 is connected to the support plate 21 through the hinge seat 22, and the two support plates 21 can stably support the main body cylinder 1.

[0044] During use, inject cement into the main body cylinder 1, then fixedly install the matching plate 42 at the upper end of the main body cylinder 1, and then move the device above the V-shaped crack through the roller 23. The roller 23 is connected to the support plate 21 through the hinge seat 22, and the two support plates 21 can stably support the main body cylinder 1 to ensure that the second empty groove 45 can cover the crack. Then, extend the two multi-stage electric telescopic rods 483 to make the pressure sensor 488 on the polishing bladder 487 on the side of the second fixing ring 484 contact the uppermost end of the V-shaped crack. Then, according to the value of the pressure sensor 488, extend and retract the first electric telescopic rod 31 and start the first motor 35. The first motor 35 drives the rotating shaft 36 to rotate, and the rotating shaft 36 cooperates to drive the first fixing body 37 to move. The first fixing body 37 drives the polishing and filling device 48 to move, so that the polishing and filling device 48 moves along the upper surface of the V-shaped crack, and at the same time records the trajectory of the V-shaped crack. Then, extend the multi-stage electric telescopic rod 483 and start the second motor 310 at the same time. Control the side of the second fixing ring 484 to be parallel to the side of the V-shaped crack by the same values of multiple pressure sensors 488. Then, start the third motor 411. The third motor 411 drives the gear 412 to rotate, and the gear 412 drives the second fixing ring 484 to rotate through the toothed ring 413. The second fixing ring 484 drives the polishing bladder 487 on the side to rotate. Lift the starting air pump 485, and the inflated polishing bladder 487 polishes the side of the V-shaped crack. During polishing, the multi-stage electric telescopic rod 483 extends and retracts, so as to smoothly polish the side of the V-shaped crack in the vertical direction. At the same time, move according to the trajectory on the surface of the V-shaped crack, and the thickness of polishing can be controlled through the value of the pressure sensor 488 to ensure that the entire side of the V-shaped crack is smoothly polished. While removing the rotten wood on the side of the V-shaped crack, ensure that the inside of the V-shaped crack is smooth, improve the connection strength between the cement and the wood during subsequent cement injection, and improve the overall strength of the building after cement injection.

[0045] When the decayed material inside the V-shaped crack is completely polished, the debris is discharged through a vacuum cleaner. Then, the second fixing ring 484 moves to the initial position through the telescoping of the first electric telescopic rod 31 and the rotation of the first motor 35. After that, it continues to drive the second fixing ring 484 to move along the track edge of the V-shaped crack. At the same time, the second electric telescopic rod 41 is extended, and the second electric telescopic rod 41 drives the limiting plate 43 to extrude the cement of the main cylinder 1. The cement moves into the discharge port 489 through the material conveying pipe 47. By contracting the multi-stage electric telescopic rod 483, the cement coming out of the discharge port 489 can be evenly smeared on the side of the V-shaped crack. When the side of the V-shaped crack is completely smeared, wait for the cement to completely solidify. Then, inject the cement completely into the V-shaped crack. When injecting the cement, since the cement on the side of the V-shaped crack has solidified, it can prevent the gas in the wooden building from overflowing into the cement inside the V-shaped crack, reduce the generation of cavities in the cement, and improve the connection strength after the cement solidifies.
