[0002] Concrete hole sealing is a method of repairing holes or defects in concrete wall structures. Usually, it is necessary to first remove loose materials, dust and impurities in the concrete wall holes to ensure that the sealing material can adhere well to the wall holes; then the sealing material is evenly filled into the wall holes to ensure that the filling material completely fills the wall holes and is compacted to remove bubbles.

[0040] When the cleaning wheel 311 reaches the hole to be blocked, the cleaning docking gear 304 engages with the docking gear 210, and the docking gear 210 rotates to drive the cleaning docking gear 304 to rotate, thereby driving the vertical gear shaft 303 and the upper bevel gear 305 to rotate, thereby driving the inner bevel gear 307, the inner groove shaft 306 and the inner gear 308 to rotate, and the rotation of the inner groove shaft 306 drives the cleaning outer cylinder 310 and the cleaning wheel 311 to rotate.

[0041] like Figure 10-12 As shown, the injection device includes an injection shell 402 fixedly mounted on the injection frame 401, a feed hopper 403 fixedly mounted on the injection shell 402, a vertical gear shaft 405 rotatably mounted on the injection shell 402, a transfer bevel gear 407, an injection docking gear 406 and an upper docking gear 416 fixedly mounted on the vertical gear shaft 405, a conveying shaft 414 rotatably mounted in the injection shell 402, a conveying bevel gear 415 fixedly mounted on the conveying shaft 414, the conveying bevel gear 415 is meshed with the upper docking gear 416, a transmission assembly 412 is provided below the injection shell 402, the transmission assembly 412 is composed of a number of bevel gears, gears and belt drives, a rotating shaft 413 rotatably mounted on the injection shell 402, and the transfer bevel gear 407 rotates through the transmission assembly 412 to drive the rotating shaft 413 to rotate.

[0042] like Figure 10-12 As shown, an insertion mechanism is provided on the injection shell 402, and the insertion mechanism includes an insertion cylinder 404 slidably mounted on the injection shell 402, a sliding column 408 is fixedly mounted on the insertion cylinder 404, the sliding column 408 is slidably mounted with the injection shell 402, a sliding column spring 409 is provided between the sliding column 408 and the injection shell 402, a vortex cam 411 is fixedly mounted on the rotating shaft 413, a push column 410 is fixedly mounted on the sliding column 408, and the push column 410 cooperates with the vortex cam 411.

[0043] When the hole to be blocked is cleaned, the switching electric cylinder 202 drives the rotating disk 201 to rotate 180 degrees, so that the insertion tube 404 reaches the hole. At this time, the docking gear 210 is meshed with the injection docking gear 406. The rotation of the docking gear 210 drives the injection docking gear 406 to rotate, driving the vertical gear shaft 405, the transmission bevel gear 407 and the upper docking gear 416 to rotate. The raw material for blocking is put into the feed hopper 403, and the upper docking gear 416 rotates to drive the conveying bevel gear 415 and the conveying shaft 414 to rotate. The conveying shaft 414 mixes and conveys the raw material and injects it into the hole through the injection shell 402 and the insertion tube 404. In the initial state, the slide column spring 409 is in a compressed state. At the same time, the transmission bevel gear 407 drives the rotating shaft 413 and the vortex cam 411 to rotate clockwise through the transmission assembly 412. When the vortex cam 411 is disengaged from the push column 410, the slide column spring 409 rebounds, driving the slide column 408 and the insertion tube 404 along the injection shell 402 pops up, and the insertion tube 404 enters the hole to be blocked. As the vortex cam 411 continues to rotate, the radius of the contact point between the vortex cam 411 and the push post 410 gradually increases, thereby pushing the push post 410 and the slide post 408 to slide along the injection shell 402. The slide post spring 409 is gradually compressed, thereby driving the insertion tube 404 to slowly retreat out of the hole, that is, the plugging material is injected from the deepest part of the hole. As the insertion tube 404 gradually retreats, the hole is gradually blocked. The sealing is from the inside out and the sealing effect is good. When the vortex cam 411 pushes the push post 410 and the sliding post 408 to the limit, the insertion tube 404 leaves the hole and the hole is sealed. If the blocked hole is a through hole, the rear side of the through hole needs to be closed. When the hole is shallow, the sliding post spring 409 will not rebound to the natural state when it rebounds, and the insertion tube 404 contacts the inside of the hole. When the vortex cam 411 rotates to contact the push post 410 again, the insertion tube 404 starts to retreat.

[0044] The working principle of a concrete hole plugging device disclosed in the present invention is as follows: the bottom motor 102 rotates to drive the worm 103 to rotate, which drives the turbine 104 and the rotating crank rod 105 to rotate, thereby driving the upper rotating rod 106 to rotate, thereby driving the lifting platform 107 to lift, thereby driving the rotating disk 201 to lift, so that the cleaning wheel 311 reaches the hole to be plugged, the switching electric cylinder 202 is extended and retracted to drive the switching rack 203 to move, thereby driving the rotating column 204 and the switching half gear 205 to rotate, thereby driving the rotating disk 201 to rotate, thereby driving the cleaning frame 301 and the injection frame 401 to move, and when the cleaning wheel 311 reaches the hole to be plugged, the cleaning pair is cleaned. The connecting gear 304 is engaged with the docking gear 210. The rotation of the docking gear 210 drives the cleaning docking gear 304 to rotate, thereby driving the vertical gear shaft 303 and the upper bevel gear 305 to rotate, thereby driving the inner bevel gear 307, the inner groove shaft 306 and the inner gear 308 to rotate. The rotation of the inner groove shaft 306 drives the cleaning outer cylinder 310 and the cleaning wheel 311 to rotate. At the same time, the rotation of the inner gear 308 drives the screw gear 313 and the bidirectional screw 312 to rotate, thereby driving the internal threaded sleeve 309 to reciprocate through the double-line thread on the bidirectional screw 312, thereby driving the cleaning wheel 311 to rotate while reciprocating in the hole to be blocked, thereby cleaning the hole to be blocked. When the hole to be blocked is cleaned, the switching electric cylinder 202 drives the rotating disk 201 to rotate 180 degrees, so that the insertion tube 404 reaches the hole. When the cleaning device or injection device reaches the working position, the card ball 212 will be stuck in the concave ball groove of the lifting platform 107 to maintain stability.At this time, the docking gear 210 is meshed with the injection docking gear 406, and the rotation of the docking gear 210 drives the injection docking gear 406 to rotate, driving the vertical gear shaft 405, the transmission bevel gear 407 and the upper docking gear 416 to rotate, and the raw material for sealing is put into the feed hopper 403, and the upper docking gear 416 rotates to drive the conveying bevel gear 415 and the conveying shaft 414 to rotate, and the conveying shaft 414 mixes and conveys the raw material, and injects it into the hole through the injection shell 402 and the insertion tube 404. In the initial state, the slide post spring 409 is in a compressed state. At the same time, the transmission bevel gear 407 drives the rotating shaft 413 and the vortex cam 411 to rotate clockwise through the transmission component 412. When the vortex cam 411 is separated from the push post 410, the slide post spring 409 rebounds, driving the slide post 408 and the insertion tube 404 to pop out along the injection shell 402, and the insertion tube 404 enters the hole to be sealed. When the vortex cam 411 continues to rotate, the radius of the contact point between the vortex cam 411 and the push post 410 gradually increases, thereby pushing the push post 410 and the slide post 408 to slide along the injection shell 402, and the slide post spring 409 is gradually compressed, thereby driving the insertion tube 404 to slowly retreat out of the hole, that is, the plugging material is injected from the deepest part of the hole. As the insertion tube 404 gradually retreats outward, the hole is blocked from the inside to the outside step by step, and the blocking effect is good. When the vortex cam 411 pushes the push post 410 and the slide post 408 to the limit, the insertion tube 404 leaves the hole and the hole is blocked. If the blocked hole is a through hole, the rear side of the through hole needs to be closed. When the hole is shallow, the slide post spring 409 will not rebound to its natural state when it rebounds, and the insertion tube 404 contacts the inside of the hole. When the vortex cam 411 rotates to contact the push post 410 again, the insertion tube 404 begins to retreat.
