Description

Technical Field

[0001] The invention relates to the technical field of tile caulking equipment, in particular to a floor tile caulking equipment for building construction. Background Art

[0002] At present, ceramic tiles are generally used to pave the floor during house decoration. Ordinary ceramic tiles will have gaps when they are laid, and dust will accumulate in the gaps, making it difficult to clean the ceramic tile floor. Therefore, ceramic tile caulking agents are needed to fill the tile gaps. In order to replace manual filling of tile gaps, floor ceramic tile caulking equipment is used in the prior art. These equipment extrude the ceramic tile caulking agents into the tile gaps while walking on the ground, and then flatten the caulking agents filling the tile gaps. However, when the caulking agents are flattened, excess caulking agents will flow to both sides and eventually stick to the ceramic tiles, and the excess caulking agents on the ceramic tiles are difficult to clean. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a floor tile caulking device for construction. During the caulking process, traceless tape is affixed on both sides of the tile gap. When the tile caulking agent is scraped flat, the excess tile caulking agent falls onto the traceless tape, and then the traceless tape is rolled up, which can prevent the excess tile caulking agent from getting on the tiles, and can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: a floor tile caulking device for construction, comprising a caulking travel mechanism, the caulking travel mechanism comprising a vehicle body, two axles rotatably mounted on the front and rear sides of the bottom of the vehicle body, each axle having a travel wheel mounted at both ends, and further comprising: The tile caulking agent extrusion mechanism includes a caulking agent extrusion end head. Two caulking agent extrusion cylinder assemblies are connected to the middle of the vehicle body through two gap alignment assemblies. The tops of the two caulking agent extrusion cylinder assemblies are respectively fixedly connected to two horizontal sliding rods. One end of the two horizontal sliding rods is respectively connected to the two ends of the horizontal sleeve in a horizontal sliding manner. The bottom end of each caulking agent extrusion cylinder assembly is connected to the top of the caulking agent extrusion end head through a discharge valve. A caulking agent follow-up extrusion control mechanism, one end of which is connected to the middle portion of the transverse sleeve, and the other end of which is connected to the front axle; The sealant scraping mechanism is installed on the bottom of the vehicle body, and the sealant scraping mechanism is located behind the sealant extrusion end; The sealant cleaning-free mechanism is installed on the lower side of the vehicle body.

[0005] The vehicle body is pushed, and the vehicle body can move on the ground with the help of the wheel axle and the traveling wheels. The caulking agent extrusion cylinder assembly contains the tile caulking agent. The gap alignment assembly is used to drive the caulking agent extrusion cylinder assembly to move left and right relative to the vehicle body, so that the caulking agent extrusion end at the bottom of the caulking agent extrusion cylinder assembly corresponds to the tile gap on the ground. When the caulking agent extrusion cylinder assembly moves left and right, the cross slide bar also moves left and right relative to the cross sleeve. After the two caulking agent extrusion ends correspond to the two tile gaps, the discharge valve is opened to push the vehicle body to move along the tile gap. The traveling wheel is in rolling contact with the ground, the wheel axle rotates, and the caulking agent is squeezed. The grout-free cleaning mechanism sticks traceless tape on both sides of the tile gap, and the front wheel axle pulls the horizontal sleeve downward through the grout follower extrusion control mechanism. The horizontal sleeve uses the grout extrusion cylinder assembly to squeeze out the internal tile grout, and the tile grout passes through the discharge valve and the grout extrusion end and falls into the tile gap. The grout leveling mechanism scrapes the tile grout at the tile gap as the vehicle body moves, and the excess tile grout sticks to the traceless tape on both sides of the tile gap. The traceless tape is torn off and reeled up to avoid excess tile grout falling on the tiles and being difficult to clean.

[0006] Furthermore, the sealant follow-up extrusion control mechanism includes a pull rope, a support, a guide wheel and a pull rope speed-changing winding assembly. The lower middle side of the transverse sleeve is connected to one end of the pull rope. A through slot is opened in the middle of the vehicle body. A support is installed at the bottom of the vehicle body in front of the through slot. The guide wheel is rotatably connected to the support. A pull rope speed-changing winding assembly is installed in the middle of the front wheel axle. The pull rope passes through the through slot and goes around from the lower side of the guide wheel. The other end of the pull rope is connected to the pull rope speed-changing winding assembly. When the vehicle body is moving, the front wheel axle drives the draw rope speed change winding assembly to rotate, and the draw rope speed change winding assembly winds the draw rope, and the draw rope is pulled to the horizontal sleeve and moves downward, so that the caulking agent extrusion cylinder assembly extrude the tile caulking agent from the bottom of the caulking agent extrusion end as the vehicle body moves. At this time, the vehicle body will extrude the tile caulking agent when it moves, and the tile caulking agent will stop being extruded when the vehicle body stops, so that the tile caulking agent is discharged evenly, and the situation that the tile caulking agent is continuously discharged after the vehicle body stops and causes uneven caulking is avoided. The draw rope speed change winding assembly can wind draw ropes of different lengths according to the setting when the wheel axle rotates one circle, thereby controlling the discharge amount of tile caulking agent per unit time when the vehicle body travels at a constant speed, and can adjust the discharge speed of tile caulking agent according to the size of the tile gap. The setting of the guide wheel prevents the draw rope from being excessively worn by friction with the front side of the through groove, and the annular draw rope limit groove provided on the guide wheel limits the draw rope.

[0007] Furthermore, the pull rope speed change winding assembly includes a winding cone sleeve, a speed change groove, a fixing sleeve and two butterfly bolts. The middle part of the front wheel axle passes through the middle part of the winding cone sleeve. A plurality of speed change grooves are opened on the outer side of the winding cone sleeve. The end of the pull rope away from the horizontal sleeve is bolted to the corresponding speed change groove. The end of the winding cone sleeve is fixedly connected to the fixing sleeve. The fixing sleeve is threaded with two butterfly bolts, and the two butterfly bolts are pressed against the side of the wheel axle. The wire winding cone sleeve can rotate relative to the front wheel axle, and can also move left and right relative to the front wheel axle. The outer diameter of the wire winding cone sleeve increases from the left end to the right end, and the bottom diameters of the multiple speed-changing grooves also increase from left to right. The number of speed-changing grooves is selected according to needs. When the pull rope is connected to the speed-changing groove on the far left, the length of the rope wound when the axle rotates one circle is the smallest, the height of the horizontal sleeve moving downward is the smallest, and the tile caulking agent squeezed out by the caulking agent extrusion cylinder assembly is also the least; when the pull rope is connected to the speed-changing groove on the far right, the length of the rope wound when the axle rotates one circle is the smallest. The degree is the largest, and the height of the horizontal sleeve moving downward is the largest. At this time, the amount of tile caulking squeezed out by the caulking agent extrusion cylinder assembly is also the largest. When the pull rope is connected to different speed reel grooves, it is necessary to loosen the butterfly bolt 2 to allow the winding cone sleeve and the fixed sleeve to move left and right along the wheel axle to ensure that the speed reel groove to which the pull rope needs to be connected corresponds to the middle of the guide wheel front and back to avoid the pull rope being pulled obliquely and disengaging from the annular pull rope limiting groove in the middle of the guide wheel. After adjustment, it is necessary to tighten the butterfly bolt 2 again to fix the fixed sleeve to the wheel axle to avoid the fixed sleeve and the winding cone sleeve rotating relative to the wheel axle to affect the winding of the pull rope.

[0008] Furthermore, the caulking agent scraping mechanism includes a gap alignment frame, a scraping plate angle adjustment assembly, and a caulking agent scraping plate. The two gap alignment assemblies are respectively fixedly connected to the two gap alignment frames. The sides of the two gap alignment frames are respectively installed with two caulking agent scraping plates through the scraping plate angle adjustment assembly. The two caulking agent scraping plates are respectively located behind and to the sides of the two caulking agent extrusion ends. The gap alignment frame moves left and right with the gap alignment assembly, allowing the caulking agent scraping plate to also correspond to the tile gaps on the floor together with the caulking agent extrusion end. The scraping plate angle adjustment assembly can drive the caulking agent scraping plate to change its angle, so that the caulking agent scraping plate and the floor have a suitable scraping angle, and also ensure that the bottom of the caulking agent scraping plate can frictionally contact the upper side of the tile.

[0009] Furthermore, the caulking agent cleaning-free mechanism includes a long axis 1, a tape releasing wheel, a traceless tape, a long axis 2 and a tape rolling and pressing rubber roller. The front side of each gap alignment frame is rotatably connected to the long axis 1, and two tape releasing wheels are respectively installed at the end of each long axis 1. The two tape releasing wheels are located on the front side of the corresponding caulking agent extrusion cylinder assembly. Two traceless tapes are respectively wrapped around the two tape releasing wheels, and a gap is left between the two traceless tapes. The bottom of the gap alignment frame is rotatably connected to the long axis 2, and a tape rolling and pressing rubber roller is installed on the long axis 2. The tape rolling and pressing rubber roller is located between the caulking agent extrusion end and the tape releasing wheel, and the traceless tape passes around the lower side of the tape rolling and pressing rubber roller. Since both the long axis one and the long axis two are installed on the gap alignment frame, the gap between the two traceless tapes can also be aligned with the tile gap. When the vehicle body moves, the bottom of the tape rolling pressing roller is close to the tile surface, and the tape rolling pressing roller rolls forward on the tile surface, pressing the two traceless tapes to both sides of the tile gap, and pulling and releasing the two traceless tapes on the two tape release wheels. Since the two tape release wheels are located on the front side of the corresponding caulking agent extrusion cylinder assembly, the traceless tape is pasted first, and then the tile caulking agent is squeezed out. Then the caulking agent scraper flattens the tile caulking agent at the tile gap, and the excess tile caulking agent moves to both sides of the caulking agent scraper, and finally falls on the traceless tape on both sides of the tile gap. After tearing off or rolling up the traceless tape, the upper side of the tile remains clean, and there is no need to clean the excess tile caulking agent on the tile.

[0010] Furthermore, the caulking agent cleaning-free mechanism further includes a mounting bracket and a release friction sleeve. Each gap alignment bracket is secured with a mounting bracket, and a release friction sleeve is mounted on the mounting bracket. The release friction sleeve is in frictional contact with the corresponding end of the long shaft (one). To prevent excessive release of the markless tape due to excessive rotation of the tape release wheel when the tape is released, the mounting bracket and release friction sleeve are provided. The mounting bracket is used to mount the release friction sleeve, which provides friction to the long shaft (one), preventing excessive release of the markless tape due to rotational inertia between the long shaft (one) and the tape release wheel.

[0011] Furthermore, the caulking agent cleaning-free mechanism further includes a long shaft three, a tape take-up wheel, and a take-up wheel chain transmission assembly. The rear end of each gap alignment frame is rotatably connected to the long shaft three. Two tape take-up wheels are installed at the end of the long shaft three. The two tape take-up wheels are located on the rear side of the corresponding caulking agent scraping plate. The two tape take-up wheels are respectively wound around the rear ends of the two corresponding traceless tapes. The two long shafts three are connected to the rear wheel axle through the take-up wheel chain transmission assembly. When the vehicle body moves, the rear wheel axle rotates, thereby driving the two long shafts three to rotate through the take-up wheel chain transmission assembly. The two drive the tape take-up wheels to rotate, so that the used traceless tape can be rolled up, eliminating the need to manually tear off the traceless tape. The diameter of the traceless tape gradually increases as it is wound on the tape take-up wheel, but this has little effect on the winding speed of the traceless tape. At most, the redundant part of the traceless tape between the tape take-up wheel and the tape rolling and pressing rubber roller will be wound up, which can be ignored.

[0012] Furthermore, it also includes a tile joint cleaning mechanism, which includes a cleaning shaft, a cleaning shaft chain transmission assembly, a prism, a tile joint cleaning roller brush, a control sleeve, a follower bent rod and an axle frame. A shaft frame is provided on the bottom front side of the vehicle body, and the bottom of the shaft frame is rotatably connected to a horizontal cleaning shaft. The two ends of the cleaning shaft are respectively fixedly connected to two prisms, and two tile joint cleaning roller brushes are respectively slidably sleeved on the two prisms. The sides of the two tile joint cleaning roller brushes that are close to each other are respectively rotatably connected to two control sleeves. The two control sleeves are respectively connected to the two gap alignment frames through two follower bent rods, and the cleaning shaft is connected to the front wheel axle through the cleaning shaft chain transmission assembly. When the vehicle body moves, the wheel axle rotates, and the cleaning shaft is driven to rotate through the transmission of the cleaning shaft chain transmission assembly. The control sleeve and the follower bent rod move with the gap alignment frame, so that the brick joint cleaning roller brush slides along the prism, ensuring that the brick joint cleaning roller brush can be aligned with the tile gap. The cleaning shaft drives the two prisms to rotate, thereby driving the brick joint cleaning roller brush to rotate. The brick joint cleaning roller brush cleans the debris in the tile gap in advance, reducing the trouble of manual cleaning.

[0013] Furthermore, it also includes a dust suction mechanism, which includes a dust suction hood, a hood frame, a dust suction hose and a vacuum cleaner body. Each follower bent rod is fixedly connected to a hood frame, and a dust suction hood is installed at the bottom of the hood frame. The dust suction hood surrounds the upper half of the corresponding brick joint cleaning roller brush. The top of the dust suction hood is connected to one end of the dust suction hose, and the other end of the dust suction hose is connected to the inlet of the vacuum cleaner body. The dust removed by the brick joint cleaning roller brush may be contaminated by the subsequent traceless tape or even the tile grout, affecting subsequent work. Therefore, the dust suction mechanism is provided. The removed dust is sucked into the vacuum cleaner body by the dust suction hood and the dust suction hose. Since the dust suction hood surrounds the upper half of the corresponding brick joint cleaning roller brush, it can greatly reduce dust and maintain a clean and tidy on-site environment.

[0014] Furthermore, the vehicle further includes a tile caulking agent adding mechanism, comprising a caulking agent barrel and an adding control assembly. The vehicle body is provided with a caulking agent barrel, the bottom of which is connected to the bottom side of the caulking agent extrusion cylinder assembly via the adding control assembly. When the tile caulking agent in the caulking agent extrusion cylinder assembly is used up, the second butterfly bolt is loosened to allow the winding cone sleeve and the fixing sleeve to rotate freely relative to the wheel axle, thereby releasing the draw cord wrapped around the winding cone sleeve. The discharge valve is then closed, and the horizontal sleeve is pulled upward. The caulking agent extrusion cylinder assembly, using the internal negative pressure, can draw the spare tile caulking agent in the caulking agent barrel into the caulking agent extrusion cylinder assembly, completing the mid-process tile caulking agent addition. The second butterfly bolt is then tightened again to re-secure the winding cone sleeve and the fixing sleeve to the wheel axle. The connection between the caulking agent barrel and the caulking agent extrusion cylinder assembly is closed, and the discharge valve is opened for reuse.

[0015] Compared with the existing technology, the beneficial effects of this floor tile caulking equipment for building construction are: 1. The floor tile caulking equipment for construction uses a tape rolling and pressing rubber roller with the bottom close to the tile surface when the vehicle body moves. The tape rolling and pressing rubber roller rolls forward on the tile surface, pressing the two traceless tapes to both sides of the tile gap, and pulling and releasing the two traceless tapes on the two tape release wheels. Since the two tape release wheels are located on the front side of the corresponding caulking agent extrusion cylinder assembly, the traceless tape is pasted first, and then the tile caulking agent is squeezed out. Then the caulking agent scraper flattens the tile caulking agent at the tile gap, and the excess tile caulking agent moves to both sides of the caulking agent scraper and finally falls on the traceless tape on both sides of the tile gap. After tearing off or rolling up the traceless tape, the upper side of the tile remains clean, and there is no need to clean the excess tile caulking agent on the tile.

[0016] 2. The floor tile caulking equipment for construction use, when the vehicle body is moving, the front wheel axle drives the pull rope speed change winding assembly to rotate, the pull rope speed change winding assembly winds the pull rope, and the pull rope is pulled to the horizontal sleeve and moves downward, so that the caulking agent extrusion cylinder assembly extrude the tile caulking agent from the bottom of the caulking agent extrusion end as the vehicle body moves. At this time, the vehicle body will extrude the tile caulking agent when it moves, and the tile caulking agent will stop being extruded when the vehicle body stops, so that the tile caulking agent is discharged evenly, avoiding the situation where the tile caulking agent continues to discharge after the vehicle body stops and causes uneven caulking. The pull rope speed change winding assembly can wind pull ropes of different lengths when the wheel axle rotates one circle according to the setting, thereby controlling the discharge amount of the tile caulking agent per unit time when the vehicle body travels at a constant speed, and can adjust the discharge speed of the tile caulking agent according to the size of the tile gap.

[0017] 3. The gap alignment frame of the floor tile caulking equipment used in construction moves left and right with the gap alignment component, so that the caulking agent scraper plate and the caulking agent extrusion end can correspond to the tile gap on the ground. The scraper plate angle adjustment component can drive the caulking agent scraper plate to change the angle, so that the caulking agent scraper plate and the ground have a suitable scraping angle, and can also ensure that the bottom of the caulking agent scraper plate can rub against the upper side of the tile.

[0018] 4. The floor tile caulking equipment for construction uses a wheel axle that rotates while the vehicle body is moving, and the cleaning shaft is driven to rotate through the transmission of the cleaning shaft chain transmission assembly. The control sleeve and the follower bent rod move with the gap alignment frame, so that the brick joint cleaning roller brush slides along the prism to ensure that the brick joint cleaning roller brush can be aligned with the tile gap. The cleaning shaft drives the two prisms to rotate, thereby driving the brick joint cleaning roller brush to rotate. The brick joint cleaning roller brush cleans the debris in the tile gap in advance, reducing the trouble of manual cleaning. The dust cleaned from the tile gap is sucked into the vacuum cleaner body by the dust suction hood and the dust suction hose. Since the dust suction hood surrounds the upper half of the corresponding brick joint cleaning roller brush, it can greatly reduce dust and maintain a clean and tidy on-site environment.

[0019] 5. When the tile caulking agent in the caulking agent extrusion cylinder assembly is used up, loosen the second butterfly bolt to allow the winding cone sleeve and the fixed sleeve to rotate freely relative to the axle, thereby releasing the pull rope wrapped around the winding cone sleeve, and then close the discharge valve and pull the horizontal sleeve upward. The caulking agent extrusion cylinder assembly can use the internal negative pressure to draw the spare tile caulking agent in the caulking agent barrel into the caulking agent extrusion cylinder assembly, which can quickly complete the addition of tile caulking agent midway.

The adjusting cross bar 21 can move left and right along the adjusting guide groove so that the caulking agent extrusion end 211 is aligned with the tile gap, and then the butterfly bolt 22 is tightened so that the butterfly bolt 22 presses against the adjusting cross bar 21 to fix the relative position of the adjusting cross bar 21 and the vehicle body 11.

[0026] The sealant extrusion cylinder assembly includes a sealant extrusion cylinder body 24, a cylinder head 25, a piston rod 26 and a sealant extrusion piston 29. Each cylinder sleeve 23 is fixedly connected to a vertical sealant extrusion cylinder body 24. The bottom of the sealant extrusion cylinder body 24 is a conical structure, and the bottom of the sealant extrusion cylinder body 24 is fixedly connected to the top of the discharge valve 210. The bottom of the discharge valve 210 is fixedly connected to the top of the sealant extrusion end head 211. The top of the sealant extrusion cylinder body 24 is fixed with a cylinder head 25 by screws. The through hole in the middle of the cylinder head 25 The inner sliding connection is provided with a vertical piston column 26, the top of the piston column 26 is fixedly connected to the end of the corresponding transverse sliding rod 27, and the bottom of the piston column 26 is fixedly connected to a caulking agent extrusion piston 29. The caulking agent extrusion piston 29 cooperates with the inner side of the caulking agent extrusion cylinder 24, and the caulking agent extrusion cylinder 24 is filled with tile caulking agent. The transverse sleeve 28 and the transverse sliding rod 27 can press the piston column 26 and the caulking agent extrusion piston 29 downward, so that the tile caulking agent can be squeezed into the tile gap through the discharge valve 210 and the caulking agent extrusion end 211.

[0027] One end of the sealant follower extrusion control mechanism 4 is connected to the middle portion of the transverse sleeve 28 , and the other end of the sealant follower extrusion control mechanism 4 is connected to the front axle 13 .

[0028] The sealant follow-up extrusion control mechanism 4 includes a pull rope 41, a support 42, a guide wheel 43 and a pull rope speed change winding assembly. The lower middle side of the transverse sleeve 28 is connected to one end of the pull rope 41. A through slot 15 is provided in the middle of the vehicle body 11. A support 42 is installed at the bottom of the vehicle body 11 in front of the through slot 15. The guide wheel 43 is rotatably connected to the support 42. The guide wheel 43 is provided with a ring-shaped pull rope limiting groove. A pull rope speed change winding assembly is installed in the middle of the front wheel axle 13. The pull rope 41 passes through the through slot 15 and goes around from the lower side of the guide wheel 43. The other end of the pull rope 41 is connected to the pull rope speed change winding assembly.

[0029] When the vehicle body 11 is moving, the wheel shaft 13 on the front side drives the pull rope speed change winding assembly to rotate, and the pull rope speed change winding assembly winds the pull rope 41, and the pull rope 41 is pulled to the horizontal sleeve 28 and moves downward, so that the caulking agent extrusion cylinder assembly extrude the tile caulking agent from the bottom of the caulking agent extrusion end 211 as the vehicle body 11 moves forward. At this time, the vehicle body 11 will extrude the tile caulking agent when it moves forward, and the vehicle body 11 will stop extruding the tile caulking agent, so that the tile caulking agent is discharged evenly, and the tile caulking agent is prevented from being stuck after the vehicle body 11 stops. To prevent uneven filling caused by continuous discharge, the rope speed change winding assembly can wind ropes 41 of different lengths when the wheel shaft 13 rotates one circle, thereby controlling the discharge amount of the tile caulking agent per unit time when the traveling speed of the vehicle body 11 is constant, and adjusting the feeding speed of the tile caulking agent according to the size of the tile gap. The setting of the guide wheel 43 prevents the rope 41 from being excessively worn due to friction with the front side of the through groove 15, and the annular rope limiting groove provided on the guide wheel 43 limits the rope 41.

[0030] The speed change winding assembly of the pull rope includes a winding cone sleeve 44, a speed change groove 45, a fixing sleeve 46 and a butterfly bolt 47. The middle part of the front wheel axle 13 passes through the middle part of the winding cone sleeve 44. A plurality of speed change grooves 45 are opened on the outside of the winding cone sleeve 44. The end of the pull rope 41 away from the horizontal sleeve 28 is bolted to the corresponding speed change groove 45. The end of the winding cone sleeve 44 is fixedly connected to the fixing sleeve 46. The fixing sleeve 46 is threaded with a butterfly bolt 47. The butterfly bolt 47 is pressed against the side of the wheel axle 13.

[0031] The wire winding cone sleeve 44 can rotate relative to the front wheel axle 13, and can also move left and right relative to the front wheel axle 13. The outer diameter of the wire winding cone sleeve 44 increases from the left end to the right end, and the bottom diameters of the multiple speed-changing grooves 45 also increase from left to right. The number of speed-changing grooves 45 is selected as needed. When the pull rope 41 is bolted to the speed-changing groove 45 on the far left, the length of the pull rope 41 wound when the axle 13 rotates one circle is the smallest, the height of the horizontal sleeve 28 moving downward is the smallest, and the tile caulking agent squeezed out by the caulking agent extrusion cylinder assembly is also the least. When the pull rope 41 is bolted to the speed-changing groove 45 on the far right, the length of the pull rope 41 wound when the axle 13 rotates one circle is the largest. The horizontal sleeve 28 moves downward to the maximum height, and at this time, the tile caulking agent squeezed out by the caulking agent extrusion cylinder assembly is also the largest. When the pull rope 41 is connected to different speed reel grooves 45, it is necessary to loosen the butterfly bolt 247 to allow the winding cone sleeve 44 and the fixed sleeve 46 to move left and right along the wheel axle 13, ensuring that the speed reel groove 45 to which the pull rope 41 needs to be connected corresponds to the middle part of the guide wheel 43 front and back to prevent the pull rope 41 from being pulled obliquely and disengaging from the annular pull rope limiting groove in the middle of the guide wheel 43. After adjustment, it is necessary to tighten the butterfly bolt 247 again to fix the fixed sleeve 46 to the wheel axle 13 to prevent the fixed sleeve 46 and the winding cone sleeve 44 from rotating relative to the wheel axle 13 and affecting the winding of the pull rope 41.

[0032] The sealant scraping mechanism 5 is installed at the bottom of the vehicle body 11 , and is located at the rear side of the sealant extrusion end head 211 .

[0033] The caulking agent scraping mechanism 5 includes a gap alignment frame 51, a scraping plate angle adjustment component and a caulking agent scraping plate 55. The two adjustment cross bars 21 in the two gap alignment components are respectively fixedly connected to the top of the two gap alignment frames 51. When the adjustment cross bar 21 is adjusted left and right relative to the vehicle body 11, it can also drive the corresponding gap alignment frame 51 to move left and right. In order to keep the gap alignment frame 51 stable, the gap alignment frame 51 can also be installed by sliding horizontally with the vehicle body 11. A matching slide bar can be set at the top of the gap alignment frame 51, and a slide groove slidably connected to the slide bar can be set at the bottom of the vehicle body 11. Two caulking agent scraping plates 55 are respectively installed on the sides of the two gap alignment frames 51 through the scraping plate angle adjustment component. The two caulking agent scraping plates 55 are respectively located on the rear sides of the two caulking agent extrusion ends 211.

[0034] The scraper plate angle adjustment assembly includes a mounting shaft 52, a retaining ring 53 and a butterfly nut 54. An axis hole is opened on the side of each gap alignment frame 51, and a mounting shaft 52 is inserted into the axis hole. The end of the mounting shaft 52 is fixedly connected to the caulking agent scraper plate 55. The mounting shaft 52 is located on one side of the gap alignment frame 51 and is fixedly sleeved with a retaining ring 53. The mounting shaft 52 is located on the other side of the gap alignment frame 51 and is threadedly connected with a butterfly nut 54. Loosening the butterfly nut 54 allows the mounting shaft 52 to rotate relative to the gap alignment frame 51, thereby adjusting the angle of the caulking agent scraper plate 55, and then tightening the butterfly nut 54 to re-fix the mounting shaft 52 and the caulking agent scraper plate 55.

[0035] The gap alignment frame 51 moves left and right with the gap alignment component, so that the caulking agent scraping plate 55 can also correspond to the tile gap on the ground together with the caulking agent extrusion end 211. The scraping plate angle adjustment component can drive the caulking agent scraping plate 55 to change its angle, so that the caulking agent scraping plate 55 and the ground have a suitable scraping angle, and can also ensure that the bottom of the caulking agent scraping plate 55 can rub against the upper side of the tile.

[0036] The sealant cleaning-free mechanism 6 is installed on the lower side of the vehicle body 11 .

[0037] The sealant cleaning-free mechanism 6 includes a long axis 1 61, a tape release wheel 62, a traceless tape 63, a long axis 2 66 and a tape rolling and pressing rubber roller 67. The front side of each gap alignment frame 51 is rotatably connected to the long axis 1 61 through a bearing. Two tape release wheels 62 are respectively installed at the end of each long axis 1 61. The two tape release wheels 62 are located on the front side of the corresponding sealant extrusion cylinder assembly. Two traceless tapes 63 are respectively wrapped around the two tape release wheels 62. A gap is left between the two traceless tapes 63 to fill the gap. The gap is set corresponding to the gap, and the bottom of the gap alignment frame 51 is rotatably connected to the long shaft 2 66 through a bearing. The long shaft 2 66 is installed with a tape rolling and pressing rubber roller 67. The tape rolling and pressing rubber roller 67 is located between the sealant extrusion end 211 and the tape release wheel 62, and the traceless tape 63 is passed around the lower side of the tape rolling and pressing rubber roller 67. The lower side of the traceless tape 63 is provided with traceless glue, and the bottom of the tape rolling and pressing rubber roller 67 is at the same horizontal height as the bottom end of the sealant extrusion end 211.

[0038] Since both the long axis 1 61 and the long axis 2 66 are mounted on the gap alignment frame 51, the gap between the two traceless tapes 63 can also be aligned with the tile gap. When the vehicle body 11 moves, the bottom of the tape rolling and pressing rubber roller 67 is close to the tile surface, and the tape rolling and pressing rubber roller 67 rolls forward on the tile surface, pressing the two traceless tapes 63 to both sides of the tile gap, and pulling and releasing the two traceless tapes 63 on the two tape release wheels 62. Since the two tape release wheels 62 are located on the front side of the corresponding caulking agent extrusion cylinder assembly, the traceless tape 63 is first pasted, and then the tile caulking agent is squeezed out. Then the caulking agent scraper 55 scrapes the tile caulking agent at the tile gap, and the excess tile caulking agent moves to both sides of the caulking agent scraper 55, and finally falls on the traceless tape 63 on both sides of the tile gap. After tearing off or rolling up the traceless tape 63, the upper side of the tile remains clean, and there is no need to clean the excess tile caulking agent on the tile.

[0039] The caulking agent cleaning-free mechanism 6 also includes a mounting bracket 64 and a release friction sleeve 65. Each gap alignment frame 51 is secured with a mounting bracket 64 via screws. A release friction sleeve 65 is mounted on the mounting bracket 64 and engages with the corresponding end of the long shaft 1 61. To prevent excessive release of the markless tape 63 due to excessive rotation of the tape release wheel 62 when the tape is released, the mounting bracket 64 and release friction sleeve 65 are provided. The mounting bracket 64 is used to mount the release friction sleeve 65. The release friction sleeve 65 provides friction for the long shaft 1 61, preventing the long shaft 1 61 and the tape release wheel 62 from releasing too much tape 63 due to rotational inertia.

[0040] The caulking agent cleaning-free mechanism 6 also includes a long shaft three 68, a tape take-up wheel 69 and a take-up wheel chain transmission assembly. The rear ends of each gap alignment frame 51 are rotatably connected to the long shaft three 68 through bearings. Two tape take-up wheels 69 are installed at the ends of the long shaft three 68. The two tape take-up wheels 69 are located on the rear sides of the corresponding caulking agent scraping plate 55. The two tape take-up wheels 69 respectively wind up the rear ends of the corresponding two traceless tapes 63. The two long shafts three 68 are connected to the rear axle 13 through the take-up wheel chain transmission assembly.

[0041] The winding wheel chain transmission assembly includes a connecting sleeve 610, sprocket one 611, chain one 612, and sprocket two 613. The ends of the two long shafts three 68 that are close to each other are respectively connected to the two ends of the connecting sleeve 610 in a transverse sliding manner. Specifically, the outer sides of the ends of the two long shafts three 68 that are close to each other are provided with limiting grooves distributed axially along the long shaft three 68, and the inner side of the connecting sleeve 610 is provided with a limiting bar that is slidably connected to the limiting groove. Sprocket one 611 is installed on the outer side of the middle part of the connecting sleeve 610, and sprocket two 613 is installed in the middle of the rear wheel shaft 13. Sprocket two 613 is connected to sprocket one 611 through chain one 612.

[0042] When the vehicle body 11 moves, it drives the sprocket 2 613 to rotate, and the transmission of the chain 1 612 and the sprocket 1 611 drives the connecting shaft sleeve 610 to rotate, thereby driving the long shaft 3 68 and the tape take-up wheel 69 to rotate. Since the two gap alignment frames 51 need to move left and right when aligning the tile gaps, they will also drive the two long shafts 3 68 to move left and right. The two long shafts 3 68 will move relative to the connecting shaft sleeve 610. Since the connecting shaft sleeve 610 may move freely left and right relative to the two long shafts 3 68, it will affect the coordinated connection of the sprocket 1 611, the chain 1 612, and the sprocket 2 613. Therefore, after adjusting the gap After the left and right positions of the alignment frame 51 are adjusted, the long shaft three 68 and the connecting sleeve 610 can be fixed with fastening screws to ensure that the left and right positions of the sprocket one 611 on the connecting sleeve 610 are stable. Alternatively, an alternative solution can be adopted to install the connecting sleeve 610 on the sleeve bracket through a bearing, and the sleeve bracket is installed on the bottom rear side of the vehicle body 11, so that the connecting sleeve 610 is stably installed on the vehicle body 11. At this time, when the gap alignment frame 51 is adjusted left and right, it will not affect the matching connection of the sprocket one 611, the chain one 612, and the sprocket two 613. Generally speaking, it is better to use the sleeve bracket to install the connecting sleeve 610.

[0043] When the vehicle body 11 moves, the wheel axle 13 on the rear side rotates, thereby driving the two long shafts 3 68 to rotate through the winding wheel chain transmission assembly, and the two drive the tape winding wheel 69 to rotate, so that the used traceless tape 63 can be wound up, and there is no need to manually tear off the traceless tape 63. The diameter of the traceless tape 63 gradually increases when it is wound on the tape winding wheel 69, but it has little effect on the winding speed of the traceless tape 63. At most, the redundant part of the traceless tape 63 between the tape winding wheel 69 and the tape rolling and pressing rubber roller 67 will be wound up, which can be ignored.

[0044] When in use, the vehicle body 11 is pushed, and the vehicle body 11 can move on the ground with the help of the wheel axle 13 and the running wheel 14. The caulking agent extrusion cylinder assembly contains the tile caulking agent. The gap alignment assembly is used to drive the caulking agent extrusion cylinder assembly to move left and right relative to the vehicle body 11, so that the caulking agent extrusion end 211 at the bottom of the caulking agent extrusion cylinder assembly corresponds to the tile gap on the ground. When the caulking agent extrusion cylinder assembly moves left and right, the horizontal sliding rod 27 also moves left and right relative to the horizontal sleeve 28. After the two caulking agent extrusion ends 211 correspond to the two tile gaps, the discharge valve 210 is opened, and the vehicle body 11 is pushed to move along the tile gap. The running wheel 14 is in rolling contact with the ground. The wheel axle 13 rotates, and the caulking agent cleaning-free mechanism 6 sticks the traceless tape on both sides of the tile gap. The front wheel axle 13 pulls the horizontal sleeve 28 downward through the caulking agent follow-up extrusion control mechanism 4. The horizontal sleeve 28 uses the caulking agent extrusion cylinder assembly to squeeze out the internal tile caulking agent. The tile caulking agent passes through the discharge valve 210 and the caulking agent extrusion end 211 and falls into the tile gap. The caulking agent leveling mechanism 5 levels the tile caulking agent at the tile gap as the vehicle body 11 moves. The excess tile caulking agent is stained on the traceless tape on both sides of the tile gap. The traceless tape is torn off and reeled up to avoid excess tile caulking agent falling on the tiles and being difficult to clean.

[0045] For example 2, please refer to Figures 1 to 9 This embodiment provides a technical solution: a floor tile caulking device for construction. The structure of this embodiment is roughly the same as that of the first embodiment, except that: A tile joint cleaning mechanism 7 is also provided, which includes a cleaning shaft 71, a cleaning shaft chain transmission assembly, a prism 75, a brick joint cleaning roller brush 76, a control sleeve 77, a follower bent rod 78 and an axle frame 79. A shaft frame 79 is provided on the bottom front side of the vehicle body 11. The bottom of the shaft frame 79 is rotatably connected to a horizontal cleaning shaft 71 through a bearing. The two ends of the cleaning shaft 71 are respectively fixedly connected to two prisms 75, and two brick joint cleaning roller brushes 76 are respectively slidably sleeved on the two prisms 75. The sides of the two brick joint cleaning roller brushes 76 that are close to each other are respectively rotatably connected to two control sleeves 77 through bearings. The two control sleeves 77 are respectively connected to the two gap alignment frames 51 through two follower bent rods 78, and the cleaning shaft 71 is connected to the front wheel axle 13 through a cleaning shaft chain transmission assembly.

[0046] The cleaning shaft chain transmission assembly includes sprocket three 72, chain two 73 and sprocket four 74. Sprocket four 74 is installed at the end of the cleaning shaft 71, and sprocket three 72 is installed on the front axle 13. Sprocket three 72 and sprocket four 74 are arranged in front and back correspondence. Sprocket three 72 is connected to sprocket four 74 through chain two 73. When the axle 13 rotates, the cleaning shaft 71 is driven to rotate through the transmission of sprocket three 72, chain two 73 and sprocket four 74.

[0047] When the vehicle body 11 moves, the wheel axle 13 rotates, and the cleaning shaft 71 is driven to rotate through the transmission of the cleaning shaft chain transmission assembly. The control sleeve 77 and the follower bent rod 78 move along with the gap alignment frame 51, so that the brick joint cleaning roller brush 76 slides along the prism 75 to ensure that the brick joint cleaning roller brush 76 can be aligned with the tile gap. The cleaning shaft 71 drives the two prisms 75 to rotate, thereby driving the brick joint cleaning roller brush 76 to rotate. The brick joint cleaning roller brush 76 cleans the debris in the tile gap in advance, reducing the trouble of manual cleaning.

[0048] For example three, please refer to Figures 1 to 9 This embodiment provides a technical solution: a floor tile caulking device for construction. The structure of this embodiment is roughly the same as that of the second embodiment, except that: A dust suction mechanism 8 is also provided, which includes a dust suction cover 81, a cover frame 82, a dust suction hose 83 and a vacuum cleaner body 84. Each follower bent rod 78 is fixedly connected to a cover frame 82 by screws, and a dust suction cover 81 is installed at the bottom of the cover frame 82. The dust suction cover 81 surrounds the upper half of the corresponding brick joint cleaning roller brush 76. The top of the dust suction cover 81 is connected to one end of the dust suction hose 83, and the other end of the dust suction hose 83 is connected to the inlet of the vacuum cleaner body 84. The vacuum cleaner body 84 is installed on the vehicle body 11. The vacuum cleaner body 84 adopts existing technology, and the control of the vacuum cleaner body 84 also adopts existing technology. The power supply scheme for the vacuum cleaner body 84 can adopt a long wire, or the required battery can be installed on the vehicle body 11, eliminating the long wire. The dust cleaned out by the brick joint cleaning roller brush 76 may be contaminated by the subsequent traceless tape 63 or even the tile caulking agent, affecting subsequent work. Therefore, a dust suction mechanism 8 is provided, and the cleaned dust is sucked into the vacuum cleaner body 84 by the dust suction cover 81 and the dust suction hose 83. Since the dust suction cover 81 surrounds the upper half of the corresponding brick joint cleaning roller brush 76, it can greatly reduce dust and maintain the cleanliness of the on-site environment.

[0049] For example 4, please refer to Figures 1 to 9 This embodiment provides a technical solution: a floor tile caulking device for construction. The structure of this embodiment is roughly the same as that of the third embodiment, except that: A tile caulking agent adding mechanism 3 is also provided, which includes a caulking agent barrel 31, a barrel cover 32 and an adding control component. The vehicle body 11 is provided with a caulking agent barrel 31, and the top opening of the caulking agent barrel 31 is threadedly connected to the barrel cover 32. The caulking agent barrel 31 contains spare tile caulking agent, and the bottom of the caulking agent barrel 31 is connected to the bottom side of the caulking agent extrusion cylinder assembly through the adding control component. When the tile caulking agent in the caulking agent extrusion cylinder assembly is used up, loosen the butterfly bolt 247 to allow the winding cone sleeve 44 and the fixing sleeve 46 to rotate freely relative to the wheel axle 13, thereby releasing the pull rope 41 wrapped around the winding cone sleeve 44, and then close the discharge valve 210, pull the horizontal sleeve 28 upward, and the caulking agent extrusion cylinder assembly can use the internal negative pressure to draw the spare tile caulking agent contained in the caulking agent barrel 31 into the caulking agent extrusion cylinder assembly, completing the mid-way addition of tile caulking agent, and then tighten the butterfly bolt 247 again to re-fix the winding cone sleeve 44 and the fixing sleeve 46 to the wheel axle 13, close the connection between the caulking agent barrel 31 and the caulking agent extrusion cylinder assembly, open the discharge valve 210 and it can be reused.

[0050] Specifically, the adding control component includes a feeding hose 33 and a feeding valve 34. The feeding valve 34 is installed at the side opening at the bottom of the caulking agent extrusion cylinder 24. The feeding valve 34 is connected to one end of the feeding hose 33, and the other end of the feeding hose 33 is connected to the bottom of the caulking agent barrel 31. When the caulking agent extrusion cylinder assembly is used to extrude the tile caulking agent, the discharge valve 210 is opened and the feeding valve 34 is closed, so that the caulking agent extrusion piston 29 in the caulking agent extrusion cylinder 24 is pressurized to extrude the tile caulking agent. When it is necessary to add spare tile caulking agent to the caulking agent extrusion cylinder assembly, the discharge valve 210 is closed and the feeding valve 34 is opened, so that the caulking agent extrusion cylinder 24 can smoothly generate negative pressure and suck the tile caulking agent in the caulking agent barrel 31.
