Description

Technical Field

[0001] The present invention relates to the technical field of decoration, and in particular to an auxiliary trolley for tile joint beautification. Background Art

[0002] When laying indoor tiles, in order to prevent the tiles from detaching or bulging due to thermal expansion and contraction, a certain gap must be left between adjacent tiles. These gaps need to be filled with caulking agent to ensure the waterproofness of the tiles on the one hand and the beauty of the entire floor on the other hand. To enhance the three-dimensional effect of tile laying, sealants of various colors are injected on the surface of the gaps to make the gaps more beautiful.

[0003] However, during the process of filling the sealant, construction workers need to manually fill it bit by bit. The filling is incomplete. After filling, it needs to be scraped flat. During the scraping process, the excess sealant will be pushed onto the tile surface, which is likely to cause the tile surface to be contaminated with caulking agent. After the sealant dries, the excess sealant is removed, resulting in waste, the process is cumbersome, and the manual labor intensity is high. Since manual caulking may cause deviation, the sealant may also be located on the tile surface. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the present invention provides an auxiliary trolley for tile joint beautification.

[0005] To achieve the above object, the present invention adopts the following technical solutions: An auxiliary trolley for tile caulking, comprising a vehicle frame, a first drive shaft rotatably arranged on the vehicle frame, a second drive shaft parallel to the first drive shaft and rotatably arranged on the vehicle frame, a base arranged at the lower middle of the vehicle frame, a third drive shaft rotatably arranged on the base, a fourth drive shaft parallel to the third drive shaft and rotatably arranged on the base, two groups of caulking devices symmetrically arranged on the vehicle frame, a calibration device arranged on the vehicle frame, a drive device arranged on the vehicle frame for driving the first drive shaft to the fourth drive shaft to rotate in the same direction, a lifting device arranged on the vehicle frame for driving the base to move, two first rollers fixedly sleeved at both ends of the first drive shaft, two second rollers fixedly sleeved at both ends of the second drive shaft, two third rollers fixedly sleeved at both ends of the third drive shaft, two fourth rollers fixedly sleeved at both ends of the fourth drive shaft; the first roller to the fourth roller have the same structure, and the first roller includes a wheel body, a first annular groove and a second annular groove arranged on the wheel body; before caulking the tiles, the whole trolley is first adjusted by the calibration device and the two groups of caulking devices, so that the two groups of caulking devices are simultaneously located in the middle of the tile gap. After the adjustment is completed, one of the groups of caulking devices is driven to reset, that is, only one group of caulking devices works during the caulking process, and the two groups of caulking devices are switched for use. During the preliminary adjustment, the two groups of caulking can confirm the position of the trolley, making the initial position of the trolley accurate. During the subsequent movement of the trolley, it is monitored by the calibration device. The drive device first drives the first drive shaft to rotate. The rotation of the first drive shaft drives the rotation of the third drive shaft. The rotation of the third drive shaft drives the rotation of the fourth drive shaft. The rotation of the fourth drive shaft drives the rotation of the second drive shaft, so that the first drive shaft to the fourth drive shaft rotate in the same direction, and the corresponding first roller to the fourth roller rotate in the same direction, thereby driving the whole trolley to move linearly along the longitudinal tile gap. When it encounters that the first roller or the second roller is about to contact the transverse tile gap, the lifting device drives the base to descend, so that the third drive shaft and the fourth drive shaft descend, and the third roller and the fourth roller descend, which is equivalent to the first roller and the second roller rising, so that the first roller and the second roller straddle the transverse tile gap. When the lifting device moves the base, the drive device can ensure the transmission between the first drive shaft and the fourth drive shaft.Before the grouting of tiles, the present invention first adjusts the whole trolley through a calibration device and two grouting devices, so that the two grouting devices are both located in the middle of the tile gap. After the adjustment is completed, one of the grouting devices is driven to reset, that is, only one grouting device works during the grouting process, and the two grouting devices are switched for use. During the preliminary adjustment, the two grouting devices can confirm the position of the trolley, making the initial position of the trolley accurate. During the subsequent movement of the trolley, it is monitored through the calibration device. Through the above settings, the grouting agent can be better located in the gap between the two tiles and move along the gap, that is, to avoid deviation during the filling process. Through the setting of the grouting device, the grouting agent can better fill the gap between the two tiles and automatically complete the scraping. During the scraping process, the excess grouting agent is collected and reused, avoiding the waste of the grouting agent. The process is simple and the degree of automation is high, thus greatly reducing the labor intensity of workers. The driving device first drives the first driving shaft to rotate. The rotation of the first driving shaft drives the third driving shaft to rotate. The rotation of the third driving shaft drives the fourth driving shaft to rotate. The rotation of the fourth driving shaft drives the second driving shaft to rotate, so that the first driving shaft to the fourth driving shaft rotate in the same direction, and the corresponding first roller to the fourth roller rotate in the same direction, thereby driving the whole trolley to move linearly along the longitudinal tile gap. When the first roller or the second roller is about to contact the transverse tile gap, the lifting device drives the base to descend, so that the third driving shaft and the fourth driving shaft descend, and the third roller and the fourth roller descend, which is equivalent to the first roller and the second roller rising, so that the first roller and the second roller cross the transverse tile gap. When the lifting device moves the base, the driving device can ensure the transmission between the first driving shaft and the fourth driving shaft.

[0033] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] As shown in Figure 1-18As shown in the figure, an auxiliary trolley for beautifying the joints of ceramic tiles includes a vehicle frame 1, a first drive shaft 2 rotatably arranged on the vehicle frame, a second drive shaft 3 arranged parallel to the first drive shaft and rotatably arranged on the vehicle frame, a base 4 arranged at the lower middle part of the vehicle frame, a third drive shaft 5 rotatably arranged on the base, a fourth drive shaft 6 arranged parallel to the third drive shaft and rotatably arranged on the base, two groups of joint beautifying devices 7 symmetrically arranged on the vehicle frame, a calibration device 8 arranged on the vehicle frame, a drive device 9 arranged on the vehicle frame for driving the first drive shaft to the fourth drive shaft to rotate in the same direction, a lifting device 10 arranged on the vehicle frame for driving the base to move, two first rollers 11 fixedly sleeved at both ends of the first drive shaft, two second rollers 12 fixedly sleeved at both ends of the second drive shaft, two third rollers 13 fixedly sleeved at both ends of the third drive shaft, and two fourth rollers 14 fixedly sleeved at both ends of the fourth drive shaft; the first roller to the fourth roller have the same structure, and the first roller includes a wheel body 111, a first annular groove 112 and a second annular groove 113 arranged on the wheel body; before beautifying the joints of ceramic tiles, first adjust the whole trolley through the calibration device and the two groups of joint beautifying devices, so that the two groups of joint beautifying devices are simultaneously located in the middle of the ceramic tile gap. After the adjustment is completed, drive one of the groups of joint beautifying devices to reset, that is, only one group of joint beautifying devices works during the joint beautifying process, and the two groups of joint beautifying devices are switched for use. During the preliminary adjustment, the two groups of joint beautifying can confirm the position of the trolley, make the initial position of the trolley accurate, and monitor it through the calibration device during the subsequent movement of the trolley. Through the above settings, the joint beautifying agent can be better located in the gap between two ceramic tiles and move along the gap, that is, avoid deviation during the filling process. Through the setting of the joint beautifying device, the joint beautifying agent can better fill the gap between two ceramic tiles and automatically complete the scraping. During the scraping process, the excess joint beautifying agent is collected and reused, avoiding the waste of the joint beautifying agent. The process is simple and the degree of automation is high, thus greatly reducing the labor intensity of workers. First, the drive device drives the first drive shaft to rotate. The rotation of the first drive shaft drives the rotation of the third drive shaft. The rotation of the third drive shaft drives the rotation of the fourth drive shaft. The rotation of the fourth drive shaft drives the rotation of the second drive shaft, so that the first drive shaft to the fourth drive shaft rotate in the same direction, and the corresponding first roller to the fourth roller rotate in the same direction, thereby driving the whole trolley to move linearly along the longitudinal gap of the ceramic tile. When the first roller or the second roller is about to contact the transverse gap of the ceramic tile, the lifting device drives the base to descend, so that the third drive shaft and the fourth drive shaft descend, and the third roller and the fourth roller descend, which is equivalent to the first roller and the second roller rising, so that the first roller and the second roller cross the transverse gap of the ceramic tile. When the lifting device moves the base, the drive device can ensure the transmission between the first drive shaft and the fourth drive shaft. At the same time, during the lifting process of the third drive shaft and the fourth drive shaft, the joint beautifying device can automatically adapt to the height and always keep filling the gap between two ceramic tiles.

[0035] The described joint beautifying device 7 includes a lifting seat 71, an adaptation component 72 fixedly arranged on the vehicle frame for driving the lifting of the lifting seat, a glue scraping component 73 fixedly arranged on the lifting seat, a fixed disk 74 fixedly arranged on the lifting seat, a first turntable 75 rotatably sleeved on the fixed disk, a first inclined surface 76, a second inclined surface 77 and a first arc surface 78 arranged on the first turntable, a plurality of liquid outlet holes 79 arranged in a graded annular distribution on the first turntable, an opening 710 arranged on the fixed disk, a first liquid inlet pipe 711 arranged on the lifting seat, a second liquid inlet pipe 712 arranged on the fixed disk for connecting the first liquid inlet pipe and the opening, a gear 713 meshed with the first turntable, a first motor 714 fixedly arranged on the lifting seat for driving the gear to rotate, and a liquid suction component 715 arranged in the fixed disk; through the adaptation component, the movement of the lifting seat can be automatically controlled, that is, the lifting seat can be kept moving horizontally, so as to ensure the horizontal movement of the glue scraping component. The first motor drives the gear to rotate, and the gear is meshed with the first turntable, so that the first turntable rotates. The joint beautifying agent enters the second liquid inlet pipe through the first liquid inlet pipe. The joint beautifying agent in the second liquid inlet pipe enters the opening. The joint beautifying agent at the opening is discharged through a plurality of liquid outlet holes at the opening to fill the gap between two tiles. Through the arrangement of a plurality of liquid outlet holes on the first turntable, the liquid outlet holes can be continuously replaced, and at the same time, the joint beautifying agent can be filled from the deep part of the tile gap to the outside, avoiding air entering the gap and affecting the filling of the joint beautifying agent, making the filling process of the joint beautifying agent more comprehensive. Through the arrangement of the first arc surface, the joint beautifying agent can be better dispersed during the discharge from the liquid outlet hole. Through the arrangement of the first inclined surface and the second inclined surface, it can be better located at the gap, playing a good guiding role. Since the fixed disk does not rotate, it is ensured that the opening always faces downwards, that is, towards the gap, so as to better fill the joint beautifying agent. After the joint beautifying agent is filled, it is leveled by the glue scraping component. The excess joint beautifying agent returns to the second liquid inlet pipe through the liquid suction component and enters the opening together with the joint beautifying agent in the second liquid inlet pipe.

[0036] The adaptation component 72 includes a first base 721 fixedly arranged on the vehicle frame, a first rotating seat 722 rotatably arranged on the first base, a second rotating seat 723, a first rotating rod 724 movably arranged through the first rotating seat, a second rotating rod 725 symmetric to the first rotating rod and movably arranged through the second rotating seat, a third rotating rod 726 with two ends respectively rotatably arranged on the first rotating rod and the lifting seat, a fourth rotating rod 727 symmetric to the third rotating rod and with two ends respectively rotatably arranged on the second rotating rod and the lifting seat, two first guide rods 728 arranged in parallel and with one end fixedly arranged on the first base, a first slider 729 movably arranged on the first guide rod, a second slider 7210 movably arranged on the first slider, a second turntable 7211 rotatably arranged at the middle of the second slider, a driving shaft 7212 with one end eccentrically fixed on the second turntable, a second motor 7213 fixedly arranged on the first base for driving the driving shaft to rotate, a first spring telescopic rod 7214 with two ends respectively rotatably arranged on the first rotating rod and the first slider, and a second spring telescopic rod 7215 symmetric to the first spring telescopic rod and with two ends respectively rotatably arranged on the second rotating rod and the first slider; by driving the driving shaft to rotate through the second single motor, the second turntable rotates with the driving shaft as the axis, so that the second slider moves on the first slider, and the first slider moves along the direction of the first guide rod. Through the arrangement of the first spring telescopic rod and the second spring telescopic rod, the first rotating rod and the second rotating rod can relatively rotate during the movement of the first slider, the third rotating rod and the fourth rotating rod can relatively rotate, and the lifting seat rises or falls. Through the arrangement of the first spring telescopic rod and the second spring telescopic rod, the adaptability during the overall movement process is greatly improved. Finally, it is ensured that the glue scraping component is always located on the tile surface and moves close to its surface. Through the above arrangement, the movement of the lifting seat is more coherent and stable during the movement process, ensuring that the glue scraping component can better adhere to the tile and move on the tile, so that the glue scraping effect is better. When the third driving shaft and the fourth driving shaft descend, the second motor drives the lifting seat to descend. Conversely, when the third driving shaft and the fourth driving shaft rise, the second motor drives the lifting seat to rise.

[0037] The caulking component 73 includes an extrusion block 731 fixedly arranged on the lifting seat, two liquid collecting plates 732 symmetrically arranged and fixedly arranged on both sides of the extrusion block, a convex block 733 arranged on the extrusion block, a second arc surface 734 arranged on the convex block, a groove 735 arranged on the convex block, a plurality of electric insertion rods 736 arranged on the extrusion block at equal intervals, a step groove 737 arranged on the liquid collecting plate, a leveling block 738 fixedly arranged on the extrusion block, a V-shaped groove 739 arranged on the leveling block, an extension plate 740 fixedly arranged on the leveling block, a plurality of liquid leveling grooves 741 arranged on the extension plate at equal intervals, and a through groove 742 arranged on the liquid collecting plate; the step grooves on the two liquid collecting plates on both sides of the extrusion block are symmetrically arranged; the caulking agent in the gap can be extruded and dispersed by the convex block on the extrusion block, and then the caulking agent is gathered by the two liquid collecting plates, so that the caulking agent can be better filled in the tile gap, avoiding the generation of air bubbles and affecting the quality and appearance of caulking. The second arc surface setting has a good buffering effect. The step groove setting on the liquid collecting plate enables the caulking agent to be better gathered. During the gathering process, it is continuously extruded downward, and finally the caulking agent is better filled. The caulking agent in the tile gap is extruded again through the setting of a plurality of electric insertion rods. The caulking agent is leveled by the leveling block. The excess caulking agent is gathered in the V-shaped groove. The V-shaped groove setting can make the leveling more comprehensive and flat. When there is too much caulking agent in the V-shaped groove, it enters between the extrusion block and the liquid collecting plate through the through groove. The excess caulking agent between the extrusion block and the liquid collecting plate returns to the second liquid inlet pipe through the liquid absorbing component. The extension plate setting avoids excessive extrusion of the caulking agent at that place and causing protrusion, so that the excess caulking agent finally returns to the second liquid inlet pipe. The liquid leveling groove setting finally makes the caulking agent flat and gathers the caulking agent inward, avoiding the caulking agent on the tile surface.

[0038] The liquid absorbing component 715 includes a liquid absorbing channel 7151 communicated with the second liquid inlet pipe and arranged on the fixed disk, a first one-way valve 7152 and a second one-way valve 7153 fixedly arranged in the liquid absorbing channel, a third one-way valve 7154 located between the first one-way valve and the second one-way valve and movably arranged in the liquid absorbing channel, and a first cylinder 7155 fixedly arranged on the fixed disk for driving the third one-way valve to reciprocate; the first cylinder drives the third one-way valve to reciprocate, so that the excess caulking agent at the liquid collecting plate can enter the liquid absorbing channel through the liquid outlet hole at that place, and the caulking agent in the liquid absorbing channel enters the second liquid inlet pipe. Through the above setting, the caulking agent can flow unidirectionally.

[0039] The calibration device 8 includes an infrared level 81 fixedly arranged on the vehicle frame, a second air cylinder 82 and a third air cylinder 83 fixedly arranged on the vehicle frame, a first double-axis air cylinder 84 fixedly arranged on the second air cylinder, a second double-axis air cylinder 85 fixedly arranged on the third air cylinder, a first receiver 86 fixedly arranged at the upper end of the first double-axis air cylinder, a first V-block 87 fixedly arranged at the lower end of the second double-axis air cylinder, a second receiver 88 fixedly arranged at the upper end of the second double-axis air cylinder, a second V-block 89 fixedly arranged at the lower end of the second double-axis air cylinder, and a third receiver 810 arranged on the vehicle frame; start the infrared level to emit two infrared light beams which are on the same line, then start the second air cylinder to enable the first double-axis air cylinder to abut against the wall, and then drive the first receiver and the first V-block to move through the first double-axis air cylinder, so that the first V-block is inserted into the tile gap. The first receiver receives the infrared light beam emitted by the infrared level. The third receiver is fixed on the opposite wall and receives the other infrared light beam. If the deviation is too large during the movement of the trolley, the third receiver will not receive the other infrared light beam. The second air cylinder and the third air cylinder are switched for use, the second double-axis air cylinder and the first double-axis air cylinder are switched for use, and finally the first receiver and the second receiver are switched for use.

[0040] The driving device 9 includes a first pulley 91 and a second pulley 92 fixedly sleeved on the first driving shaft, a third pulley 93 and a fourth pulley fixedly sleeved on the third driving shaft, a fifth pulley and a sixth pulley 96 fixedly sleeved on the fourth driving shaft, a seventh pulley 97 fixedly sleeved on the second driving shaft, a third motor 98 fixedly arranged on the vehicle frame, an eighth pulley 99 arranged on the third motor, a first belt 910 wound around the eighth pulley and the first pulley, a second belt 911 wound around the second pulley and the third pulley, a third belt 912 wound around the fourth pulley and the fifth pulley, a fourth belt 913 wound around the sixth pulley and the seventh pulley, and two sets of tensioning components 914 respectively used to keep the second belt and the fourth belt in tension; the third motor drives the eighth pulley to rotate, so that the first belt runs, the first driving shaft rotates, the second belt runs, the third pulley rotates, the third driving shaft rotates, the fourth pulley rotates, the third belt runs, the fifth pulley rotates, the fourth driving shaft rotates, the sixth pulley rotates, the fourth belt runs, the seventh pulley rotates, and the second driving shaft rotates. Through the above settings, the first driving shaft to the fourth driving shaft can rotate simultaneously and in the same direction. During the movement of the third driving shaft and the fourth driving shaft, the second belt and the fourth belt are tensioned by the two sets of tensioning components respectively to ensure that the first driving shaft can drive the third driving shaft and the fourth driving shaft can drive the second driving shaft.

[0041] The tensioning assembly 914 includes a second base 9141 rotatably sleeved on the first drive shaft, a third base 9142 rotatably sleeved on the third drive shaft, two second guide rods 9143 arranged in parallel and respectively penetrating through and movably arranged on the second base and the third base at both ends, a third slider 9144 movably arranged on the two second guide rods, a fifth rotating rod 9145 rotatably arranged on the third slider, a first small roller 9146 and a second small roller 9147 rotatably arranged at both ends of the fifth rotating rod, a first spring 9148 respectively fixed at both ends on the third slider and the second base, a second spring 9149 respectively fixed at both ends on the third slider and the third base, and a torsion spring 9150 respectively fixed at both ends on the third slider and the fifth rotating rod; during the lifting process of the third drive shaft, the fifth rotating rod rotates, and the wear between the fifth rotating rod and the second belt is reduced through the first small roller and the second small roller. Through the setting of the torsion spring, a torsional force can always be generated on the fifth rotating rod to ensure the tension of the second belt. During the lifting process of the third drive shaft, the positions between the third drive shaft and the first drive shaft also change simultaneously, causing the second base and the third base to move on the second guide rods and rotate. The elastic forces of the first spring and the second spring are the same, so that the third slider is always located in the middle of the second base and the third base, and the fifth rotating rod is located in the middle of the second belt, thereby better tensioning the second belt.

[0042] The lifting device 10 includes four third guide rods 101 penetrating through and movably arranged on the vehicle frame and fixed at the other ends on the base, third springs 102 sleeved on the third guide rods and respectively fixed at both ends on the third guide rods and the vehicle frame, a first screw rod 103, a second screw rod 104, a third screw rod 105 and a fourth screw rod 106 arranged on the vehicle frame and rotatably arranged at one end on the base, a fourth motor 107 fixed on the vehicle frame, a fifth belt 108 wound around the first screw rod and the fourth motor, a sixth belt 109 wound around the first screw rod and the second screw rod, a seventh belt 1010 wound around the second screw rod and the third screw rod, and an eighth belt 1011 wound around the third screw rod and the fourth screw rod; by driving the fifth belt to run through the fourth motor, the first screw rod rotates, the sixth belt runs, the second screw rod rotates, the seventh belt runs, the third screw rod rotates, the eighth belt runs, and the fourth screw rod rotates. Through the above settings, the first screw rod to the fourth screw rod can rotate in the same direction, thereby jointly driving the base to lift. Through the setting of the third guide rods, the base can move along the direction of the third guide rods during the lifting process, making the movement of the base more stable. By driving the fifth belt to run in the reverse direction through the fourth motor, the base moves in the reverse direction. Through the setting of the third springs, the movement of the base can be more coherent.

[0043] The above-mentioned first to fourth motors can be obtained by purchasing in the market.
