[0036] As Figure 2 、 Figure 6 and Figure 8-Figure 10 shown, it further includes a universal shaft 401. One end of the universal shaft 401 is connected to the handle of the booster 102, and the other end of the universal shaft 401 is hinged to the connecting frame 305. When the staff presses the handle of the booster 102, the connecting frame 305 can slide horizontally on the round cover 304. Elastic telescopic frames 402 are symmetrically fixedly connected to the front wall of the frame 1, and two groups of driving components are symmetrically connected. The driving components are composed of a first guide wheel, a second guide wheel and a pull rope. Among them, two first guide wheels are symmetrically rotatably connected to the front wall of the frame 1, two second guide wheels are symmetrically rotatably connected to the front wall of the frame 1, the two second guide wheels are distributed on the upper and lower sides of the two first guide wheels, one ends of the two pull ropes are fixedly connected to the front end of the annular track 301, the other ends of the two pull ropes are respectively wound around the corresponding first guide wheel and second guide wheel, and are fixedly connected to the telescopic ends of the corresponding elastic telescopic frames 402. A plurality of uniformly distributed card slots are opened on the sides of the telescopic ends of the two elastic telescopic frames 402 that are away from each other. Guide shafts A 403 are symmetrically fixedly connected to the front side of the frame 1. A push frame 404 is slidably sleeved on the guide shaft A 403. The push frame 404 is slidably connected to the outer wall of the frame 1. Convex shafts are fixedly connected to both sides of the sealing plate 202. The convex shafts are inserted into the corresponding sealing frames 201 and slide therein. The push frame 404 is used in cooperation with the convex shafts. An elastic member C is arranged between the push frame 404 and the frame 1. The elastic member C is a compression spring. The elastic member C is sleeved on the guide shaft A 403. An elastic wedge-shaped block A 405 that is used in cooperation with a plurality of card slots at the telescopic end of the elastic telescopic frame 402 is vertically slidably connected in the push frame 404. The inclined surface angle at the rear side of the elastic wedge-shaped block A 405 is greater than the inclined surface angle at the front side.

[0037] As Figure 9-10 shown, it further includes a guide shaft B 501. Guide shafts B 501 are symmetrically fixedly connected to the front side of the frame 1. The guide shafts B 501 are slidably connected to the corresponding push frames 404 in a penetrating manner. Rectangular grooves are opened on the sides of the outer walls of the two guide shafts B 501 that are close to each other. A ratchet rack 502 that is used in cooperation with the push frame 404 is slidably connected in the rectangular grooves. An elastic member D is arranged between the ratchet rack 502 and the rectangular grooves. The elastic member D is a compression spring.

[0038] As Fig.10 shown, it further includes a C-shaped frame 701. C-shaped frames 701 are fixedly connected to the sides of the two ratchet racks 502 that are away from each other. The C-shaped frames 701 are slidably connected to the corresponding guide shafts B 501 in a penetrating and perpendicular manner. When the two C-shaped frames 701 move away from each other, the two ratchet racks 502 can be driven to move away from each other.

[0039] As Figure 2As shown, it also includes a movable frame 801, the outer wall of the frame 1 is symmetrically slidably connected to the movable frame 801, the movable frame 801 is used in conjunction with the convex shaft of the blocking plate 202, the outer wall of the frame 1 is symmetrically fixed with a rectangular plate 802, and an elastic member E is arranged between the rectangular plate 802 and the movable frame 801, and the elastic member E is a compression spring.

[0040] Initially, the elastic member A is in a released state, the fan-shaped box A205 is located on the upper side, the fan-shaped box A205 is connected to the special-shaped tube 203, the fan-shaped box A205 is filled with water, the fan-shaped plate A601 is located on the side of the fan-shaped box A205 away from the frame 1, and the top of the elastic wedge block A405 is inserted into the corresponding elastic expansion frame 402 The rear side of the slot is inserted into the slot. Before filling and repairing the cracks in the concrete wall, it is necessary to clean the inside of the crack to improve the bonding effect of the adhesive. First, the staff will fit the rear side of the frame 1 to the crack of the concrete wall, and use several blocking frames 201 and blocking plates 202 to completely cover the crack, firmly adsorb the four manual suction cups 101 to the concrete wall, and then press the booster 102. The handle (booster 102 is a prior art and will not be described in detail here) causes the booster 102 to push the fan-shaped plate A601 to slide toward the side close to the frame 1. The fan-shaped plate A601 pushes the water in the fan-shaped box A205 into the special-shaped tube 203. The water enters the cracks of the concrete wall through the special-shaped tube 203 to clean the cracks. At the same time, the handle of the booster 102 pulls the connecting frame 305 through the universal shaft 401. The connecting frame 305 drives the two elastic limit blocks 306 therein to move horizontally toward the front side. The elastic limit blocks 306 squeeze the adjacent cones 307. The two cones 307 are subjected to force so that the two connecting rods 303 drive the annular track 301 to slide toward the front side through the rotating ring 302. The annular track 301 pulls the two driving components. The pull rope in the middle, the pull rope is forced to pull the telescopic end of the elastic telescopic frame 402 to shrink and slide. When the telescopic end of the elastic telescopic frame 402 slides, the several card grooves at the bottom thereof squeeze the inclined surface on the front side of the elastic wedge block A405. Due to the angle characteristics of the inclined surface on the front side of the elastic wedge block A405, the elastic wedge block A405 cannot shrink and slide under force. The elastic wedge block A405 drives the push frame 404 to slide backward along the outer wall of the guide shaft A403 and the guide shaft B501. The elastic member C is forced to shrink. During the sliding process, the push frame 404 squeezes the adjacent ratchet bar 502. The ratchet bar 502 is forced to slide to the side away from the push frame 404. The elastic member D is forced to shrink. As the push frame 404 slides, the ratchet bar 502 moves between the push frame 404 and the elastic member D. The push frame 404 continuously slides back and forth up and down under the action of, when the push frame 404 stops sliding, the push frame 404 no longer squeezes the ratchet bar 502, the elastic member D is released to drive the ratchet bar 502 to slide and reset, the ratchet bar 502 limits the push frame 404, so that the elastic member C remains in a contracted state, the push frame 404 is restricted and cannot be reset, and then the staff releases the handle of the booster 102, the handle of the booster 102 is reset and squeezes the connecting frame 305 through the universal shaft 401, the connecting frame 305 drives the two connecting rods 303 to reset through the two cones 307, the two connecting rods 303 drive the annular track 301 to slide and reset through the rotating ring 302, the annular track 301 no longer pulls the telescopic end of the elastic telescopic frame 402 through the pull rope in the drive assembly,The telescopic end of the elastic telescopic frame 402 releases and slides to reset, and drives the pull rope in the driving assembly to reset. During the resetting process of the telescopic end of the elastic telescopic frame 402, the telescopic end of the elastic telescopic frame 402 squeezes the inclined surface on the rear side of the elastic wedge block A405 through a plurality of card slots. Due to the angle characteristics of the inclined surface on the rear side of the elastic wedge block A405, the elastic wedge block A405 continuously shrinks and slides under the action of a plurality of card slots until the telescopic end of the elastic telescopic frame 402 is reset, and then the above steps are repeated until the side wall of the pushing frame 404 contacts the convex shaft of the blocking plate 202, and the pushing frame 404 squeezes the convex shaft, so that the convex shaft drives the blocking plate 202 to increase the fit to the concrete wall. , and the convex shaft squeezes the corresponding blocking frame 201, and the elastic member A is extended by force, so that the several blocking frames 201 increase the fit strength to the concrete wall, thereby preventing water from flowing out of the cracks in the concrete wall. When the cracks in the concrete wall are full of water, the water in the fan-shaped box A205 can no longer continue to be discharged through the special-shaped pipe 203. At this time, the staff can feel that the booster 102 can no longer push the fan-shaped plate A601 to move, thereby completing the water injection work in the cracks of the concrete wall. By injecting water into the cracks of the concrete wall, the cracks can be cleaned. At this time, the amount of water entering the cracks of the concrete wall is the same as the amount of adhesive filled in the cracks later. , Example 2

[0041] like Fig.11 As shown, it also includes a sliding ring 901, and the sliding ring 901 is provided on the two connecting rods 303 for common sliding sleeve. The end of the sliding ring 901 away from the frame 1 is symmetrically fixed with an unlocking sleeve 902, and the unlocking sleeve 902 is slidably connected to the corresponding connecting rod 303, and the unlocking sleeve 902 is used in conjunction with the elastic limit block 306.

[0042] like Fig.12 As shown, it also includes an air pump 1001, and the air pump 1001 is inserted into the special-shaped tube 203 and the round cover 304. The air pump 1001, the fan-shaped box A205 and the fan-shaped box B206 form a cylinder when combined. The outer wall of the air pump 1001 is provided with a hemispherical groove C1002 used in conjunction with the elastic limit pin 204. The piston end of the air pump 1001 is used in conjunction with the booster 102, and the booster 102 can blow air into the cracks of the concrete wall through the air pump 1001.

[0043] like Figure 3 As shown, a counterweight block 1101 is also included. The counterweight block 1101 is embedded and fixedly connected to the bottom of one end of the special-shaped tube 203. The counterweight block 1101 is used to control the rotation angle of the special-shaped tube 203.

[0044] Initially, the installation directions of the fan-shaped box B206 and the fan-shaped box A205 are opposite, no adhesive is filled in the fan-shaped box B206, the fan-shaped plate B602 and the fan-shaped plate A601 are on the same vertical plane, when the crack of the concrete wall is inclined, the rear side of the frame 1 is attached to the crack of the concrete wall, and the placement angle of the frame 1 is consistent with the direction of the crack. When the frame 1 is tilted, the counterweight block 1101 in the special-shaped tube 203 drives the special-shaped tube 203 to maintain the same position through the influence of its own gravity. Figure 3 The state shown in the figure makes the booster 102 always maintain the state no matter the frame 1 is placed at any angle. Figure 1The shown placement state is achieved to facilitate the operation of the staff. When the sector plate A601 moves, the magnet A inside the sector plate A601 attracts the magnet B inside the sector plate B602, causing the sector plate B602 to move synchronously with the sector plate A601 inside the sector box B206, and continuously increasing the cavity generated between the front side of the sector plate B602 and the front side of the inner wall of the sector box B206. After completing the water injection work into the cracks of the concrete wall, the staff rotates counterclockwise the cylinder composed of the sector box A205, the sector box B206 and the air pump 1001, and pinches the special-shaped pipe 203. The hemispherical grooves A207 on the sector box A205 and the sector box B206 squeeze the corresponding elastic limit pins 204, and the hemispherical groove C1002 on the air pump 1001 squeezes the corresponding elastic limit pin 204. The three elastic limit pins 204 are simultaneously stressed and contract and slide, and the sector box A205, the sector box B206 and the air pump 1001 rotate and exchange positions, making the air pump 1001 on the upper side. The output end of the air pump 1001 is communicated with the special-shaped pipe 203. Then the staff pulls and makes the two U-shaped frames 701 move away from each other. The two U-shaped frames 701 drive the two ratchet racks 502 to slide away from each other. The elastic member D is stressed and contracts. After the ratchet rack 502 slides, it no longer contacts the corresponding push frame 404. At the same time, the staff presses the two elastic wedge-shaped blocks A405, making the two elastic wedge-shaped blocks A405 contract and slide away from each other. After the elastic wedge-shaped blocks A405 slide, they disengage from several card slots at the telescopic ends of the corresponding elastic telescopic frames 402, enabling the push frame 404 to move. The elastic member C is released and drives the push frame 404 to slide back to its original position. The push frame 404 no longer contacts the convex shaft of the sealing plate 202. Then the staff拨动 the movable frame 801 forward. The elastic member E is stressed and contracts. After the movable frame 801 moves, it contacts and squeezes the convex shaft of the sealing plate 202. The convex shaft is stressed and drives the sealing plate 202 to slide. The elastic member B is stressed and contracts. After the sealing plate 202 slides, a notch appears on the front wall of the corresponding sealing frame 201. The water in the cracks of the concrete wall can flow out through the notch of the sealing frame 201. At the same time, the staff presses the handle of the booster 102. Under the action of the handle, the booster 102 pushes the piston end of the air pump 1001 to reciprocate. The output end of the air pump 1001 blows air into the cracks of the concrete wall through the special-shaped pipe 203. While achieving the effect of assisting the water to drain from the cracks, by the rapid flow of air in the cracks, increasing the air pressure in the cracks, the water can discharge the impurities in the cracks at high speed when discharging, so as to achieve the effect of cleaning the cracks, to prevent the adhesive from entering the cracks and being diluted by water. At the same time, under the action of the handle of the booster 102, the push frame 404 slides backward again until the side wall of the push frame 404 contacts the convex shaft of the sealing plate 202. Release the movable frame 801. The elastic member E is released and drives the movable frame 801 to slide back to its original position. Then continue to press the handle of the booster 102 until the convex shaft squeezes the corresponding sealing frame 201.The plurality of sealing frames 201 are used to increase the squeezing force on the concrete wall again, thereby preventing the adhesive from flowing out of the cracks of the concrete wall when the adhesive is subsequently injected into the cracks.

[0045] Then the staff slides the sliding ring 901 to the front side, and the sliding ring 901 drives the two unlocking sleeves 902 to be inserted into the connecting frame 305. The two unlocking sleeves 902 squeeze the inclined surfaces of the corresponding elastic limit blocks 306, and the elastic limit blocks 306 shrink and slide under the force, and no longer contact the cone 307, so that the connecting frame 305 can move. Then the booster 102 and the round cover 304 are moved to the side away from the cone 307 and removed, so that the connecting frame 305 is separated from the two cones 307, and the staff moves the fan-shaped box A205 and the fan-shaped box B206 to the side away from the special-shaped tube 203, and the fan-shaped box A205 and the fan-shaped box B206 pass through the hemispherical groove A207 thereon. The adjacent elastic limit pins 204 are squeezed, and the elastic limit pins 204 are squeezed, contracted and slid until the fan box A205 and the fan box B206 are completely separated from the special-shaped tube 203, and the elastic limit pins 204 are released from the restriction and slide to reset. Then the staff separates the fan box A205 from the fan box B206 and fills the fan box B206 with adhesive. It is worth noting that at this time, the volume of the cavity formed between the front side of the fan plate B602 and the front side of the inner wall of the fan box B206 is equal to the volume of the crack in the concrete wall. After the filling is completed, the fan box B206 is rotated to swap the positions of its two ends so that the end of the fan box B206 close to the hemispherical groove B208 faces The fan-shaped tube 203 is then fitted with the fan-shaped box A205 and the fan-shaped box B206 and the air pump 1001, so that the fan-shaped box B206 is on the upper side and is inserted into the special-shaped tube 203. During this process, the outer walls of the fan-shaped boxes A205 and B206 squeeze the adjacent elastic limit pins 204, causing the elastic limit pins 204 to shrink and slide. Subsequently, the hemispherical groove A207 of the fan-shaped box A205 is aligned with the corresponding elastic limit pin 204, and the elastic limit pin 204 is released to slide into the hemispherical groove A207 to limit the fan-shaped box A205. The hemispherical groove B208 of the fan-shaped box B206 is aligned with the corresponding elastic limit pin 204, and the elastic limit pin 204 is released to slide into the hemispherical groove B 208 limits the sector box B206, and then the staff slides the sliding ring 901 to the rear side, the sliding ring 901 drives the two unlocking sleeves 902 away from the cone 307, aligns the two elastic limit blocks 306 in the connecting frame 305 with the two cones 307 respectively, and pushes the connecting frame 305 backward, so that the inclined surfaces of the two elastic limit blocks 306 are respectively in contact with and squeezed with the inclined surfaces of the two cones 307, the elastic limit blocks 306 are forced to shrink and slide until the inclined surfaces of the elastic limit blocks 306 pass over the inclined surfaces of the cone 307, the elastic limit blocks 306 are released and reset and contact with the vertical surface of the cone 307, thereby completing the installation of the booster 102 and the round cover 304.

[0046] At this time, the fan-shaped box B206 is connected to the special-shaped tube 203, and the staff presses the handle of the booster 102. Under the action of the handle, the booster 102 pushes the fan-shaped plate B602 in the fan-shaped box B206 to the side close to the frame 1, and the fan-shaped plate B602 pushes the adhesive in the fan-shaped box B206 into the special-shaped tube 203. The adhesive enters the cracks of the concrete wall through the special-shaped tube 203 to achieve filling and repair. While filling and repairing the cracks, under the action of the handle of the booster 102, the pushing frame 404 slides to the rear again, thereby increasing the fit of several sealing frames 201 and sealing plates 202 to the concrete wall, thereby preventing the adhesive from flowing out of the cracks of the concrete wall when the adhesive is injected into the cracks.

[0047] When the adhesive completely enters the crack, the staff releases the manual suction cup 101 so that the manual suction cup 101 no longer adheres to the concrete wall, and then removes the entire device to complete the crack filling and repair work on the concrete wall. After the adhesive solidifies, the concrete wall surface can be made smooth and flat without the need to polish the wall.

[0048] Although the present invention is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications may be made to the present invention without departing from the principle and spirit of the present invention defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, not to limit the present invention, but the scope of protection is limited by the content of the claims.
