Description

Technical Field

[0001] The invention belongs to the technical field of using a traction and lifting device to perform spraying treatment in gaps of building components, and specifically relates to an intelligent recognition and spraying treatment device for edge joints of wall column and beam tops of assembled buildings. Background Art

[0002] Prefabricated buildings are a type of construction method in which building components (such as walls, floor slabs, beams, columns, etc.) are prefabricated in factories and then transported to construction sites for assembly. The joints of the exterior walls of prefabricated buildings refer to the connection gaps between the prefabricated exterior wall panels in prefabricated buildings. These joints are usually distributed horizontally and vertically, and their sealing quality directly affects the overall performance of the building. Since there are joint gaps between the exterior wall components of prefabricated buildings, if these gaps are not handled properly, a series of problems will occur, such as water leakage, wind leakage, thermal bridge effects, etc., which will affect the energy efficiency, structural durability and comfort of use of the building. Therefore, the sealing treatment of the joints is very important, and the sealing, waterproofness and thermal insulation performance of the gaps must be ensured to ensure the overall function and service life of the building.

[0003] In existing prefabricated building construction, the treatment of exterior wall joints usually relies on manual gluing or simple semi-automatic equipment. Manual gluing requires construction workers to operate at high altitudes to evenly apply sealant to the joints. This method is time-consuming, labor-intensive, and prone to inconsistent sealing effects due to different construction conditions (such as weather, light, and construction worker skills). Some more advanced construction sites may use simple glue spraying equipment, but these devices can usually only perform single-function spraying, making it difficult to achieve automated horizontal and vertical gap processing. In addition, existing equipment mostly relies on manual movement and operation, and cannot monitor and adjust the spraying effect in real time, resulting in unstable construction quality.

[0004] The existing technologies generally have the following problems and shortcomings: 1. Low construction efficiency: Manual gluing or semi-automatic equipment has low efficiency, especially in high-rise buildings, and requires frequent lifting of equipment, which increases construction time and labor costs. 2. Low construction accuracy: The uniformity of manual gluing is not good, and it is easy to have phenomena such as missing glue, excessive glue or hollowing, resulting in unstable sealing effect. 3. Low construction safety: In high-altitude operations, manual operations pose great safety risks, especially in complex environments. Workers are easily affected by external conditions (such as wind and weather), increasing the risk of construction accidents. 4. Sealing effect is difficult to guarantee: In the existing technology, the construction quality is highly dependent on the skills and experience of the construction personnel. The bonding between the sealant and the substrate is not stable enough, and it is easy to cause sealing failure due to residues or surface contamination, and there is a lack of effective quality control measures.

[0005] Therefore, developing an intelligent and multifunctional exterior wall joint processing system that can automatically complete the glue spraying operation of horizontal and vertical gaps, monitor the glue spraying effect in real time, automatically lay the cushioning strips and clean the gap surface will significantly improve the shortcomings of the existing technology and improve the construction quality and efficiency of prefabricated buildings.

DETAILED DESCRIPTION

[0035] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0036] Example 1: After the butt joint construction of the prefabricated building is completed, there are a large number of butt joint gaps, which are distributed horizontally and vertically, which not only affects the appearance, but may also cause problems such as leakage and thermal bridge effect. According to the "Technical Code for Prefabricated Concrete Structures" JGJ1-2014, the width of the joints on the exterior walls of prefabricated buildings should not be less than 15mm, and is usually designed to be 20mm in actual projects. In order to ensure the performance of the sealant, it is generally stipulated that the thickness of the sealant should not be less than 10mm and the width of the joint should not be greater than 40mm. The width-to-thickness ratio of the sealant is usually 2:1, and the minimum is not less than 1:1. The spraying system 9 used in the embodiment is a device that performs hoisting and spraying construction on the butt joints of the exterior wall based on a traction and lifting device. As Figure 1 and Figure 2 As shown, the device mainly includes a hanging basket device 1, a transverse frame 2, a turning mechanism 3, a telescopic mechanism 4, a nozzle adjustment mechanism 5 and a spraying system 9.

[0037] Specifically, Figure 2 As shown, the hanging basket device 1 includes a frame 11, a rope motor 12, a safety clamp 13, a transverse channel 14, a track groove 15, a rope 16, a safety rope 17, a side camera 18 and a middle camera 19. The rope motors 12 are fixedly installed on the left and right sides of the frame 11, and the ropes 16 are wound around the rope wheels of the rope motors 12 on each side, and the top of each rope 16 is fixed to the cantilever end of the fixed hanger on the roof. Safety clamps 13 are also installed on the left and right sides of the frame 11, and the safety clamps 13 on each side are equipped with safety ropes 17, and the top of each safety rope 17 is fixed to the cantilever end of the fixed hanger on the roof. By controlling the rotation of the rope motors 12 on both sides, the lifting and lowering movement of the entire frame 11 can be controlled.

[0038] A transverse channel 14 is provided on the front side (the side close to the wall) of the frame 11, two parallel track grooves 15 are fixed at the bottom of the transverse channel 14, and a transverse frame 2 is installed on the upper side of the track grooves 15. Usually, extreme position sensors are installed at the front and rear ends of the track grooves 15, and when the controller receives the corresponding sensor signal, it controls the transverse frame 2 to stop and move in the reverse direction. Side cameras 18 are fixed on the left and right sides of the frame 11, and a center camera 19 is installed on the upper part of the transverse frame 2. Fig.12As shown, the data lines of the side camera 18 and the middle camera 19 are respectively connected to the signal input end of the controller. The controller determines the overall lifting height of the hanging basket according to the signals of the left and right side cameras 18 to confirm the position of the horizontal joint, so as to stop at the horizontal joint and perform the horizontal glue spraying operation. The controller determines the position of the vertical joint according to the signal of the middle camera 19, so as to control the transverse frame 2 to move the vertical joint position and perform the vertical glue spraying operation. At the same time, the middle camera 19 moves with the telescopic mechanism 4 and the injection nozzle 94 to monitor the progress and quality of the glue spraying in real time, which can increase the real-time monitoring and feedback adjustment functions, help to ensure the uniformity of the sealant coating, improve the construction quality, and avoid rework. For example, the middle camera 19 is used to monitor the overflow amount after the injection nozzle 94 sprays glue into the joint seal, and ensure that the glue coating is at the overflow seam position, which is most conducive to the scraping operation. When the depth of the joint is inconsistent, the moving speed of the telescopic mechanism 4 and the injection nozzle 94 can be changed through such monitoring to avoid the problem of hollow drum or overflow of sufficient glue.

[0039] like Figure 2 As shown, the spraying system 9 includes a glue storage tank 91, a glue delivery pump 92, a glue delivery pipe 93 and an injection nozzle 94. The glue storage tank 91 and the glue delivery pump 92 are fixed on the top of the transverse frame 2, the input end of the glue delivery pump 92 is connected to the bottom of the inner cavity of the glue storage tank 91, and the output end of the glue delivery pump 92 is connected to the injection nozzle 94 through the glue delivery pipe 93. Select suitable joint materials, such as silicone rubber, polyurethane sealant, etc., and introduce them into the glue storage tank 91. The side wall of the glue storage tank 91 has an interlayer, and an electric heating device is installed in the interlayer. The outer wall of the glue storage tank 91 has an insulation layer to ensure that these materials have good adhesion and flowability within a suitable stable range.

[0040] like Figure 3 As shown, the transverse frame 2 includes a box body 21, a lower support 22, a running wheel 23, a running motor 24, a main shaft 25, a bevel gear set 26 and an upper support 27. The lower supports 22 are fixed below the left and right side walls of the box body 21, and a running wheel 23 is installed at the bottom of each lower support 22. Each running wheel 23 is sleeved in a corresponding track groove 15. Figure 4 As shown, a driving chamber is provided at the bottom of the box body 21, and the rotating shafts of a pair of left and right running wheels 23 pass through the driving chamber of the box body 21. A running motor 24 and a main shaft 25 are installed longitudinally in the driving chamber, and the running motor 24 is connected to the main shaft 25 by transmission. The two ends of the main shaft 25 are connected to the rotating shafts of each pair of running wheels 23 by transmission through a bevel gear set 26. At the same time, upper supports 27 are fixed on both sides of the top of the box body 21, and a transverse roller 28 is vertically installed in each upper support 27. Track beams 29 are fixed on both sides of the top of the transverse movement channel 14, and each transverse roller 28 is supported on the inner side wall of the track beam 29.

[0041] like Figure 4 As shown, the flip mechanism 3 includes a central rotating tube 31, a radial rod 32, a base 33 and a flip push rod 34. A through hole is arranged in the middle of the frame 11 along the horizontal direction, and a sleeve is installed in the through hole, and the central rotating tube 31 is sleeved in the sleeve. A radial rod 32 is fixed in the radial direction on the inner end circumference of the central rotating tube 31, and a base 33 is fixed at the bottom of the box body 21. A flip push rod 34 is hinged between the base 33 and the radial rod 32. The flip push rod 34 is preferably an electric push rod, and is controlled by the controller to move telescopically. When the flip push rod 34 is extended, the radial rod 32 is located in the vertical position, and when the flip push rod 34 is retracted, the radial rod 32 is located in the horizontal position. Usually, limit stops are arranged on the outer side of the vertical position and the lower side of the horizontal position, and position pressure touch switches are arranged on the limit stops respectively. After the controller detects the pressure touch switch signal, it controls the flip push rod 34 to stop. A rotating disk 35 is fixed to the outer end of the central rotating tube 31. When the flip push rod 34 is telescopically moved, the rotating disk 35 can be controlled to rotate 90 degrees clockwise or counterclockwise. A telescopic mechanism 4 is fixed to the outer side of the rotating disk 35. Therefore, when the flip push rod 34 is telescopically moved, the telescopic mechanism 4 can be controlled to be in a horizontal state or a vertical state as a whole. In the horizontal state, it is used to spray glue on the horizontal butt joints, and in the vertical state, it is used to spray glue on the vertical butt joints.

[0042] like Figure 5 and Figure 6 As shown, the telescopic mechanism 4 includes a frame seat 41, a fixed shaft 42, a moving shaft 43, a sliding shaft 44, a slider 45, a screw 46, a telescopic motor 47, a main swing rod 48 and a push-pull rod 49. The frame seat 41 includes a rectangular frame and upper and lower bottom surfaces, a fixed shaft 42 is transversely installed on the front side of the rectangular frame, a guide groove 441 is provided on the two side walls of the rear side of the rectangular frame, and a sliding shaft 44 is transversely installed in the guide groove 441. The fixed shaft 42 is hinged with the main swing rod 48, the sliding shaft 44 is hinged with the push-pull rod 49, the distal ends of the main swing rod 48 and the push-pull rod 49 are hinged together through the moving shaft 43, and the distal end of the main swing rod 48 is connected to a transverse connecting rod 481. A slider 45 is fixed in the middle of the sliding shaft 44, a screw sleeve is installed in the center of the slider 45 along the longitudinal direction, a screw rod 46 is installed in the screw sleeve, and a telescopic motor 47 is fixed in the middle of the rear end of the frame seat 41, and the rotating shaft of the telescopic motor 47 is transmission-connected with the screw rod 46.

[0043] A nozzle adjustment mechanism 5 is installed on the transverse connecting rod 481 at the end of the main swing rod 48, and a spray nozzle 94 is installed in the nozzle adjustment mechanism 5. Fig.11As shown, the nozzle adjustment mechanism 5 includes a tube seat 51, a rotating sleeve 52, a strip hole 53, a guide rod 54, a spring 55, a spring seat 56 and a main roller 57. The lower end of the tube seat 51 is fixed with a rotating sleeve 52, and the rotating sleeve 52 moves the shaft 43 and can rotate. A strip hole 53 is provided in the middle of the horizontal connecting rod 481, and a guide rod 54 is vertically fixed on the upper rear side of the tube seat 51, and the guide rod 54 is led out from the strip hole 53. A spring seat 56 is fixed at the end of the guide rod 54, and a spring 55 is connected to the inner side of the spring seat 56. A roller seat is provided on the side of the main swing rod 48 facing the wall, and a main roller 57 is installed on the roller seat. Therefore, the tube seat 51 can swing and reset adaptively, and the main roller 57 presses against the outer wall 81. The self-adaptive swinging and resetting pipe seat 51 is used to prevent the injection nozzle 94 from elastically avoiding obstacles when it moves in the joint, thereby avoiding damage to the injection nozzle 94; the main roller 57 pressed against the outer wall 81 controls the depth of the injection nozzle 94 into the gap, thereby preventing the injection nozzle 94 from directly touching the bottom surface 82 of the joint.

[0044] A scraper 58 is installed on the front side of the main swing rod 48, and the scraper 58 can slide and lock relative to the main swing rod 48. Figure 6 As shown, an adjustment groove 581 is provided on the side wall of the main rocker arm 48, and a clamping platform 582 is respectively provided on the left and right sides of the scraper 58. The clamping platforms 582 on both sides are respectively matched and fitted in the corresponding adjustment grooves 581 and can slide. Locking wires 583 are respectively installed on the left and right sides of the scraper 58. When the locking wires 583 are screwed, the clamping platform 582 and the adjustment groove 581 can be fixed together.

[0045] When the groove of the butt joint is deep, the lining strip 65 must be installed in the butt joint before the glue spraying operation can be carried out. In order to minimize the frequency of the reciprocating movement of the hanging basket, a padding mechanism 6 can be added on the basis of the above scheme, and the glue spraying operation can be carried out by using the spray nozzle 94 while the lining strip 65 is installed in the butt joint. Figure 7 and Figure 8 As shown, the padding mechanism 6 includes a center rod 61, a pressure plate 62, a traction seat 63 and a middle tension spring 64. In the middle of the rotating shaft of the main roller 57, the center rod 61 is hinged by a shaft sleeve, and a freely rotating pressure plate 62 is installed at the end of the center rod 61, and the circumferential edge of the pressure plate 62 contains convex and concave teeth. A traction seat 63 is arranged in the middle of the horizontal connecting rod 481, and a middle tension spring 64 is connected between the traction seat 63 and the middle of the center rod 61, so that the center rod 61 carrying the pressure plate 62 can swing upward naturally. When the pressure plate 62 is located in the groove of the butt joint, it is elastically pressed against the surface of the cushion strip 65. When the telescopic mechanism 4 moves forward with the transverse frame 2, the pressure plate 62 rolls along the outer surface of the cushion strip 65, and continuously presses the cushion strip 65 into the bottom of the groove of the butt joint.

[0046] Prefabricated components may have residues when demoulding, such as concrete, mortar, wood chips, etc. These residues may affect the contact between the sealant and the substrate. The glue joints need to be cleaned before construction to ensure effective contact between the sealant and the substrate to ensure effective bonding and sealing between the sealant and the substrate. In order to ensure that the surface to be treated is clean, dust-free, dry and free of oil and other pollutants, an air-blowing and slag-clearing mechanism 7 can be added on the basis of the above scheme to clean the dust particles in the joints to improve the sealing effect of the glue coating. Fig. 9 and Fig.10 As shown, the air blowing and slag cleaning mechanism 7 includes a side spring rod 71, a side tension spring 72, an auxiliary roller 73, a stabilizing block 74, an air blowing pipe 75 and an air nozzle 76. The side spring rods 71 ​​are hinged at both ends of the rotating shaft of the main roller 57, and the auxiliary roller 73 is installed between the ends of the side spring rods 71 ​​on both sides. A stabilizing block 74 is fixedly installed in the middle of the rotating shaft of the auxiliary roller 73, and an air nozzle 76 is fixed through the center of the stabilizing block 74. The rear end of the air nozzle 76 is connected to the air outlet of the air pump through the air blowing pipe 75, and the air pump is controlled to work or stop by the controller. Under the isolation effect of the cushion strip 65, the high-pressure wind will not enter the glue spraying area.

[0047] Based on the above scheme, the specific steps of using the device are as follows: 1. Equipment preparation and installation: hoist the hanging basket device 1 to the designated position of the outer wall, ensure that the hanging rope motor 12, safety clamp 13 and other equipment are firmly installed, and fix the hanging rope 16 and safety rope 17 to the fixed hanger on the roof. After the equipment is firmly installed, ensure safety and reliability during high-altitude operations.

[0048] 2. Glue spraying operation: Start the spraying system 9 and adjust the position of the spray nozzle 94 to align it with the joint. According to the position information provided by the side camera 18 and the middle camera 19, the glue spraying operation of the joint is performed horizontally and vertically respectively. The telescopic mechanism 4 adjusts the moving speed and angle of the spray nozzle to ensure uniform glue spraying. The sealant is evenly applied and the gap is completely covered to prevent water leakage and thermal bridge effect, thereby improving the sealing performance of the exterior wall.

[0049] 3. Real-time monitoring and adjustment: During the glue spraying process, the central camera 19 monitors the glue application of the spray nozzle 94 in real time to ensure that the glue does not overflow excessively or is insufficiently applied. When the depth of the joint is inconsistent, the moving speed of the telescopic mechanism 4 is controlled to make automatic adjustments. Through real-time monitoring and adjustment, hollowing, glue leakage or overflow problems are avoided to ensure a good sealing effect.

[0050] 6. Equipment flipping and position adjustment: When glue spraying operations in different directions are required, the flip mechanism 3 is used to adjust the angle of the nozzle so that it is aligned with the horizontal or vertical joint. The transverse frame 2 moves in the track groove 15 to ensure that the equipment can cover all joint positions. The position and angle of the equipment can be flexibly adjusted to ensure that glue can be evenly sprayed on both horizontal and vertical joints.

[0051] 5. Laying of gasket strips (if necessary): When the butt joint is deep, start the gasket mechanism 6 to press the gasket strip 65 into the bottom surface 82 of the gap. The pressure plate 62 rolls along the surface of the gasket strip to press it evenly into the bottom of the butt joint. Ensure that the gasket strip is pressed into the seam smoothly to reduce the depth of the butt joint and facilitate the subsequent gluing construction.

[0052] 6. Clean the joint surface (if necessary): Start the air blowing and cleaning mechanism 7, and use the air nozzle 76 to clean the dust and residue in the joint to ensure that the gap is clean and free of impurities.
