Description

Technical Field

[0001] This invention relates to the field of construction site equipment technology, specifically to a sealing device and method for sealing openings in the exterior walls of prefabricated buildings. Background Technology

[0002] Prefabricated building exterior walls are assembled on-site from vertical PC components. Due to construction requirements, it is necessary to leave openings for formwork reinforcement, tie rods, and external scaffolding installation on the vertical PC components, resulting in numerous through-holes in the exterior walls of prefabricated buildings. These openings require significant manpower and resources to seal later. Typically, workers seal these openings from the outside using suspended platforms, which poses significant safety hazards. Furthermore, the sealing process is complex and inefficient; additionally, the large number of openings and the high-altitude work often lead to poor sealing quality, resulting in a greater risk of subsequent water leakage.

[0065] The above-mentioned and other technical features and advantages of the present invention will be described in more detail below with reference to the accompanying drawings.

[0066] Example 1

[0067] This embodiment provides a technical solution: a device for sealing openings in the exterior walls of prefabricated buildings, such as... Figure 1 and Figure 11 As shown, it includes a walking mechanism, a wall-mounting mechanism, a texturing and dust-removing mechanism 2, a paint application mechanism 6, a mortar sealing mechanism 5, an atomizing mechanism 4, a foaming agent filling mechanism 3, a positioning camera 8, and a controller.

[0068] The walking mechanism is mounted on the rooftop wall, which allows the device to move laterally along one wall of the building. The walking mechanism also has the function of adjusting the vertical movement of the wall-mounted mechanism, thereby moving the wall-mounted mechanism to any position on one wall of the building, so as to carry out construction work on all the openings on one wall.

[0069] The wall-mounting mechanism includes an outer fixed ring 14, a rotating ring 11, and a first driving component. The outer fixed ring 14 is connected to the walking mechanism to achieve the hanging. The rotating ring 11 is rotatably installed in the inner ring of the outer fixed ring 14. The first driving component drives the rotating ring 11 to rotate circumferentially within the outer fixed ring 14. The texturing and dust-removing mechanism 2, the foaming agent filling mechanism 3, the atomizing mechanism 4, the mortar sealing mechanism 5, and the paint application mechanism 6 are all installed on the side of the rotating ring 11 close to the wall. The controller is used to control the operation of the walking mechanism, the wall-mounting mechanism, the texturing and dust-removing mechanism 2, the paint application mechanism 6, the mortar sealing mechanism 5, the atomizing mechanism 4, and the foaming agent filling mechanism 3. The controller can control the operation of the driving component to rotate and adjust the rotating ring 11 to the corresponding position to perform the corresponding operation. The controller and the positioning camera 8 form a video system, which can remotely observe the real-time situation of the wall construction.

[0070] The first driving component includes an outer gear ring 13 fixed to the rotating ring 11, a fourth motor (not shown in the figure) fixed to the rotating ring 11, and a third gear 12 fixed to the output end of the fourth motor. The third gear 12 is meshed with the outer gear ring 13. When the fourth motor is running, the rotating ring 11 can be driven to rotate through the cooperation between the outer gear ring 13 and the third gear 12.

[0071] The textural cleaning mechanism 2 is used to roughen the edges of the opening and clean the dust, increasing the strength of the subsequent mortar bonding; the foaming agent filling mechanism 3 is used to fill the middle position of the opening with foaming agent, which can fill the local cavity inside the opening and play the role of thermal bridging and sealing; the atomizing mechanism 4 is used to atomize the outside of the opening; the mortar sealing mechanism 5 is used to fill the opening outside the foaming agent with mortar; the paint application mechanism 6 is used to apply waterproof paint to the outside of the mortar; the positioning camera 8 is installed on the outer fixing ring 14 for identification and positioning. The walking mechanism and the first driving component drive the wall-mounted mechanism to move according to the feedback of the positioning camera 8, so as to realize that the textural cleaning mechanism 2, the foaming agent filling mechanism 3, the atomizing mechanism 4, the mortar sealing mechanism 5 or the paint application mechanism 6 are aligned with the opening to be constructed.

[0072] The atomizing mechanism 4, the mortar sealing mechanism 5, and the paint application mechanism 6 are all rotatably mounted on the rotating ring 11 via a rotating seat, so that they can always maintain a horizontal state according to their own gravity, which can ensure their stability and prevent the raw materials inside from surging. When the texturing and cleaning mechanism 2, the foaming agent filling mechanism 3, the atomizing mechanism 4, the mortar sealing mechanism 5, and the paint application mechanism 6 rotate to the highest point of the rotating ring 11, the working ends of the texturing and cleaning mechanism 2, the foaming agent filling mechanism 3, the atomizing mechanism 4, the mortar sealing mechanism 5, and the paint application mechanism 6 are located at the same point, that is, this point is the construction station.

[0073] In this embodiment, the sealing of the opening can be carried out automatically, which reduces the labor intensity of construction workers, speeds up the work, and improves safety performance.

[0074] Example 2

[0075] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figure 1 and Figure 11 As shown, in order to better realize the present invention, the following configuration is adopted: In this embodiment, the walking mechanism includes a U-shaped frame 71, a plurality of first drive wheels 72, a plurality of load-bearing wheels 75, a first telescopic rod 73, a plurality of second drive wheels 74, a rope lifting machine 76, and at least two steel wire ropes 77.

[0076] Multiple load-bearing wheels 75 are installed on the lower surface of the transverse portion of the U-shaped frame 71. In use, the load-bearing wheels 75 travel on the top of the wall enclosure, supporting the U-shaped frame 71. Multiple first drive wheels 72 are installed on the inner surface of one vertical portion of the U-shaped frame 71. A first telescopic rod 73 is fixed to another vertical portion of the U-shaped frame 71, and multiple second drive wheels 74 are fixed to the telescopic end of the first telescopic rod 73 via connecting plates. Both the first drive wheels 72 and the second drive wheels 74 have their own drive mechanisms. By extending the telescopic end of the first telescopic rod 73, the first drive wheels 72 and the second drive wheels 74 can be driven. The two drive wheels 74 press against the wall enclosure. Running the first drive wheel 72 and the second drive wheel 74 can drive the U-shaped frame 71 to move along the wall enclosure. The rope lifting machine 76 is installed on the upper surface of the transverse part of the U-shaped frame 71. One end of the steel wire rope 77 is wound around the rope lifting machine 76. The steel wire rope 77 can be contracted and released by the rope lifting machine 76, thereby adjusting the height of the wall hanging mechanism. The outer side of the U-shaped frame 71 is equipped with a guide wheel 78. The steel wire rope 77 passes around the guide wheel 78, which can guide the steel wire rope 77 and avoid friction between the steel wire rope 77 and the surface of the U-shaped frame 71.

[0077] U-shaped frames 16 are fixed to both the upper and lower ends of the outer fixing ring 14. Two support legs 15 are fixed to each of the two U-shaped frames 16. Universal wheels are installed at the ends of the support legs 15. The support legs 15 can support the U-shaped frames 16, and the universal wheels can prevent the wall from being scratched by the support legs 15, making movement more convenient. The other end of the steel wire rope 77 is fixedly connected to the upper U-shaped frame 16. In this embodiment, the positioning camera 8 is fixed to the upper U-shaped frame 16.

[0078] Example 3

[0079] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figure 2As shown, in order to better realize the present invention, the following configuration is adopted: In this embodiment, the texturing and dust removal mechanism 2 includes a second telescopic rod 21, a first motor 22, an insert rod 24, a first texturing knife 25 and a second texturing knife 26.

[0080] The second telescopic rod 21 is fixed to the rotating ring 11. The first motor 22 is installed at the telescopic end of the second telescopic rod 21. The insertion rod 24 is installed at the output end of the first motor 22. The first texturing knife 25 is detached and installed at one end of the insertion rod 24 near the first motor 22. The second texturing knife 26 is detached and installed at the other end of the insertion rod 24, so that the first texturing knife 25 and the second texturing knife 26 can be replaced. The distance between the first texturing knife 25 and the second texturing knife 26 is greater than the thickness of the wall.

[0081] The first texturing knife 25 includes a first cylinder and a plurality of first triangular pieces fixed to the outer circumference of the first cylinder.

[0083] In use, the end of the insert rod 24 is inserted into the corresponding opening through the cooperation of the walking mechanism and the second telescopic rod 21. It should be noted that when inserting the second texturing knife 26 into the opening, the second triangular piece of the second texturing knife 26 should face upwards, and the insert rod 24 should be adjusted downwards by a certain size to avoid interference between the second triangular piece and the inner wall of the opening. When the second texturing knife 26 passes through the opening, the walking mechanism adjusts the insert rod 24 to overlap with the center of the opening, and then the first motor 22 is activated to rotate the first texturing knife 25, extending the telescopic end of the second telescopic rod 21. The outer edge of the opening can then be texturized and chamfered using the first texturing knife 25. Then, the telescopic end of the second telescopic rod 21 is retracted, and the inner edge of the opening is texturized and chamfered using the second texturing knife 26. The inner edge of the opening is also treated in this way. After completion, the insert rod 24 can be removed from the opening by inserting the insert rod 24, thus completing the texturization treatment of the opening.

The air nozzle 23 is installed on the first motor 22, and the air outlet of the air nozzle 23 is attached to the insertion rod 24. The air pump can be installed externally, such as on the roof of a high-rise building. While texturing the opening, the air pump can be run, and compressed air will be sprayed out through the air nozzle 23 and enter the opening to clean the dust inside the opening.

[0092] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figure 5-8As shown, in order to better realize the present invention, the following configuration is adopted: the mortar sealing mechanism 5 includes a mortar box 51, a second fixing ring 52, a first stirring component 53, a second feed inlet 54, a mortar pump 55, a first conveying pipe 56, a second conveying pipe 57, a fourth telescopic rod 58, and a blocking plate 510.

[0093] The second fixing ring 52 is sleeved and fixed on the outer circumference of the mortar tank 51. The second fixing ring 52 is rotatably installed on the rotating ring 11 through the rotating seat. The first stirring component 53 is fixed at the upper end of the mortar tank 51. The first stirring component 53 adopts a conventional structure to prevent mortar from settling. The second feed port 54 is set at the upper end of the mortar tank 51 to add mortar material and is equipped with a sealing cover. The mortar pump 55 is installed at the lower end of the mortar tank 51. One end of the first conveying pipe 56 is fixed to the output end of the mortar pump 55. One end of the second conveying pipe 57 is slidably inserted into the other end of the first conveying pipe 56. The fourth telescopic rod 58 is fixed to the outer surface of the first conveying pipe 56. The first conveying pipe 56 has a first elongated hole arranged along its axial direction. The telescopic end of the fourth telescopic rod 58 is fixed to the second conveying pipe 57 through the first connecting block. The first connecting block passes through the first elongated hole. The plug 510 is fixed to the other end of the second conveying pipe 57.

[0094] like Figure 8 As shown, during use, by operating the fourth telescopic rod 58, the total length of the first conveying pipe 56 and the second conveying pipe 57 can be adjusted, thereby driving the blocking plate 510 into the opening to adhere to the foaming agent. When the mortar pump 55 is running, the mortar in the mortar tank 51 is drawn into the opening through the first conveying pipe 56 and the second conveying pipe 57. The blocking plate 510 is adapted to the diameter of the opening to prevent mortar from overflowing. While the mortar is gradually injected into the opening, the fourth telescopic rod 58 is simultaneously retracted until the blocking plate 510 moves to the outside of the opening.

[0095] The mortar sealing mechanism 5 also includes a mortar smoothing component 59, which is used to smooth the mortar on the outside of the opening to be consistent with the wall surface, avoiding grooves or protrusions. The mortar smoothing component 59 is set at the end of the first material conveying pipe 56 and includes a smoothing ring 591, an extrusion member 592, a rotary connector 593, a coupling structure 595, and a second driving member 594. The extrusion member 592 is installed at the end of the first material conveying pipe 56, and the smoothing ring 591 is rotatably installed on the extrusion member 592 through the rotary connector 593. The blocking plate 510 is rotatably connected to the second material conveying pipe 57. The coupling structure 595 is used to axially connect the smoothing ring 591 and the blocking plate 510 after the second material conveying pipe 57 shrinks. The second driving member 594 is used to drive the blocking plate 510 and the smoothing ring 591 to rotate synchronously to achieve smoothing of the mortar at the opening.

[0096] Furthermore, the extrusion member 592 provides a rotating and rearwardly cushioned structure for the smoothing ring 591. The extrusion member 592 includes multiple buffer members and a mounting ring 5924 distributed annularly on the outside of the first feed pipe 56. The buffer members include a mounting plate 5921, a guide rod 5922, and a spring 5923. The mounting plate 5921 is fixed to the first feed pipe 56, the guide rod 5922 is slidably mounted on the mounting plate 5921, the mounting ring 5924 is fixed to the ends of the guide rods 5922 of the multiple buffer members, and the spring 5923 is installed between the mounting plate 5921 and the mounting ring 5924. The smoothing ring 591 is rotatably mounted on the mounting ring 5924 through a rotating connector 593. The rotating connector 593 includes an annular groove and a slip ring. The groove is formed in the smoothing ring 591, and the slip ring is fixed to the mounting ring 5924 and slidably connected to the annular groove. The cross-section of both the annular groove and the slip ring is T-shaped.

[0097] Furthermore, the second driving component 594 includes a second motor 5941, a first gear 5942, and a first internal gear ring 5943. The second motor 5941 is mounted on the first conveying pipe 56. The first internal gear ring 5943 is fixed to the smoothing ring 591. The first gear 5942 is fixed to the output end of the second motor 5941 and meshes with the first internal gear ring 5943. The axial dimension of the first internal gear ring 5943 is larger than the axial dimension of the first gear 5942. That is, when the first internal gear ring 5943 moves axially a certain distance, it can still ensure that the first gear 5942 meshes with the first internal gear ring 5943.

[0098] Furthermore, the coupling structure 595 includes multiple grooves 5951 and multiple protrusions 5952. The multiple grooves 5951 are formed on one side of the blocking plate 510, and the multiple protrusions 5952 are fixed to the inner ring of the smoothing ring 591. After the second conveying pipe 57 retracts, the multiple protrusions 5952 enter the multiple grooves 5951 one by one, thereby axially limiting the blocking plate 510 and the smoothing ring 591.

[0099] As the fourth telescopic rod 58 retracts, the blocking disc 510 moves towards the side of the smoothing ring 591, causing the protruding rod 5952 to enter the groove 5951. Due to the force of the spring 5923, the blocking disc 510 and the smoothing ring 591 remain on the same plane. At this point, grouting can be stopped, and the second motor 5941 can be started to drive the blocking disc 510 and the smoothing ring 591 to rotate. Both of them smooth the mortar at the opening, making it flat with the wall surface.

[0100] Example 7

[0101] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figure 9-10As shown, in order to better realize the present invention, the following configuration is adopted: the paint application mechanism 6 includes a paint tank 61, a third fixing ring 62, a second stirring component 63, a third feed port 64, a paint pump 65, a third conveying pipe 66, a fourth conveying pipe 67, a paint smoothing component 68, and a fifth telescopic rod 610.

[0102] The third fixing ring 62 is sleeved and fixed to the outer circumference of the paint tank 61. The third fixing ring 62 is rotatably mounted on the rotating ring 11 via a rotating seat. The second stirring element 63 is set in the paint tank 61. The second stirring element 63 adopts a conventional stirring structure and is used to stir the waterproof paint in the paint tank 61 to prevent it from settling. The paint pump 65 is installed at the bottom of the paint tank 61. One end of the third conveying pipe 66 is fixed to the output end of the paint pump 65. The fourth conveying pipe 67 is slidably inserted into the other end of the third conveying pipe 66. The fifth telescopic rod 610 is fixed to the third conveying pipe 65. On the outer surface of the material pipe 66, the fifth telescopic rod 610 has a second elongated hole arranged along its axial direction. The telescopic end of the fifth telescopic rod 610 is fixed to the fourth material conveying pipe 67 through the second connecting block, and the second connecting block passes through the second elongated hole. The paint smoothing component 68 is disposed at the end of the fourth material conveying pipe 67. By extending the telescopic end of the fifth telescopic rod 610, the fourth material conveying pipe 67 can be extended to one side of the wall, and the paint smoothing component 68 is close to the wall. When the telescopic end of the fifth telescopic rod 610 is retracted, the paint smoothing component 68 is moved away from the wall to facilitate movement.

[0103] Furthermore, the paint smoothing assembly 68 includes a third motor 681, a second internal gear ring 682, a second gear 683, four rotating rods 684, two scrapers 686, and a rotating cylinder 687. The rotating cylinder 687 is rotatably connected to the end of the fourth feed pipe 67. The four rotating rods 684 are arranged in a ring and fixed to the end of the rotating cylinder 687. Two of the rotating rods 684 have internal cavities that communicate with the rotating cylinder 687. The outer side of the internal cavity is connected to a slurry outlet slit 685 arranged along the length direction of the rotating rod 684. The two scrapers 686 are fixed to the outer surface of the other two rotating rods 684. The third motor 681 is fixed to the outer side of the fourth feed pipe 67. The second internal gear ring 682 is fixed to the four rotating rods 684, and the center of the second internal gear ring 682 and the rotating cylinder 687 are located at the same point. The second gear 683 is fixed to the output end of the third motor 681 and meshes with the second internal gear ring 682.

[0104] When the waterproof coating is injected into the third delivery pipe 66 through the coating pump 65, the waterproof coating will flow through the fourth delivery pipe 67, the rotating cylinder 687, the inner cavity, and finally out from the grout outlet 685. The rotating rod 684 is driven to rotate by the cooperation of the third motor 681, the second gear 683 and the second internal gear ring 682, so that the waterproof coating will be applied to the wall surface and the solidified mortar. At the same time, the scraper 686 will apply the waterproof coating to complete the waterproofing measures on the outside of the opening.

[0105] Example 8

[0106] This embodiment provides a technical solution: a sealing method for the prefabricated building exterior wall opening sealing device applied in Embodiment 1, comprising the following steps:

[0107] Step 1: Install a walking mechanism on the roof, control the position of the wall-mounted mechanism through the walking mechanism, and align the corresponding working mechanism with the opening with the assistance of positioning camera 8;

[0108] Step 2: Drive the rotating ring 11 to rotate through the first driving component, so that the roughening and dust removal mechanism 2 is located at the construction position. Use the roughening and dust removal mechanism 2 to roughen the inner and outer edges of the opening and clean away the dust generated during roughening.

[0109] Step 3: Drive the rotating ring 11 to rotate through the first driving component, so that the foaming agent filling mechanism 3 is located at the construction position. According to the diameter and depth of the opening, use the foaming agent filling mechanism 3 to inject a certain amount of foaming agent into the middle of the opening. The foaming agent expands and seals the opening.

[0110] Step 4: Drive the rotating ring 11 to rotate through the first driving component, so that the atomizing mechanism 4 is located at the construction position, and use the atomizing mechanism 4 to perform atomization treatment on the outside of the opening;

[0111] Step 5: Drive the rotating ring 11 to rotate through the first driving component, so that the mortar sealing mechanism 5 is located at the construction position. Use the mortar sealing mechanism 5 to fill the opening outside the foaming agent with waterproof mortar to fill the opening.

[0112] Step 6: Drive the rotating ring 11 to rotate through the first driving component, so that the paint application mechanism 6 is located at the construction position, and apply waterproof paint to the outside of the solidified mortar using the paint application mechanism 6.

[0113] After performing step two at the same opening, move to the next vertical opening and repeat step two. Continue this process for the first batch of openings, then move to the first batch and perform step three. Since the foaming agent needs time to expand, after completing step three at all the first batch of openings, proceed with steps two and three for the second batch of openings. Once steps two and three are complete for the second batch of openings, return to the first batch and perform steps four and five. Repeat this process in sections until all openings under the same wall location have completed step five. Then, begin step six again from the top down.

Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, all of which will fall within the protection scope of the present invention.
