[0050] The specific embodiment of the wall and floor tile auxiliary paving device involved in the utility model is as follows Figures 1 to 18 As shown, the device mainly includes a traveling frame 1, a rotating arm 2, a lifting arm 3, a lowering arm 4 and a working frame 5. The position of the device is adjusted by moving the traveling frame 1, and the operation process of the device is adjusted by relative movement of the rotating arm 2, the lifting arm 3, the lowering arm 4 and the working frame 5.

[0051] Wherein, the structure of walking frame 1 is as follows Figures 1 to 4 As shown, it includes a base frame 11, and four universal wheels 12 are arranged at the four corners of the bottom of the base frame 11. The universal wheels 12 are rubber universal casters with a height of 150 mm. The two universal wheels 12 at the rear side are equipped with foot brakes to facilitate braking and parking operations. The four universal wheels 12 can rotate 360 ​​degrees in situ when walking, which is convenient and flexible to operate in a small space. A box-shaped rectangular frame 13 is arranged on the base frame 11, and two handlebars 16 are arranged on the top of the rear side of the rectangular frame 13. The handlebars 16 can be used as a walking cart, and can also be used as a base for a control mechanism. The control mechanism is fixed on the handlebars 16 for easy operation; the handlebars 16 can also be used as a stable support for tiles. When scraping the bottom of the tiles, the bottom surface of the tiles can be placed upward for more stability.

[0052] A control button 19 is provided on the handlebar 16, and a driving handle 17 is provided on the left side of the handlebar 16. Two pull ropes 153 are connected to the driving handle 17, one of which is an unlocking rope 76 and the other is a locking rope 87.

[0053] A holding handle 18 is provided on the right side of the handlebar 16 , and a holding rope 93 is connected to the holding handle 18 . When the holding handle 18 is swung to one side, the holding rope 93 is tightened, and when it is swung to the other side, the holding rope 93 is released.

[0054] A counterweight bin 14 and a power bin 15 are provided inside the traveling frame 1, wherein the power bin 15 is located in front of the counterweight bin 14, and an electric winch 151 is arranged inside the power bin 15, and the electric winch 151 is connected to the control button 19 on the handlebar 16. The worker presses the control button 19 to realize the forward and reverse control operation of the electric winch 151, and a pull rope 153 is connected to the electric winch 151, and the pull rope 153 is used to control the relative movement of the lifting arm 3, the lowering arm 4 and the working frame 5. The power bin 15 fixes the electric winch 151 and places the battery 152, and the charging port of the battery 152 is exposed. Sound insulation cotton is pasted around the power bin 15 to reduce the noise generated by the electric winch 151.

[0055] The counterweight bin 14 can be made into a sand-loading counterweight box or a block counterweight. The bottom of the counterweight box adopts a 2:1 slope design, combined with a pull-out sand-leaking door, which is convenient for sand leakage and sand cleaning. The upper part of the counterweight bin 14 has an upward flip cover plate, which is convenient for sand loading, cleaning and maintenance. The counterweight bin 14 is designed to balance the weight of the wall tiles during the tiling process. When the weight of the tiles is greater than the weight of the box body and the counterweight, a foot pedal can be added to the rear side of the counterweight box and below the handlebar 16 to balance the weight generated by the front side with the weight of the worker himself. Sandbags can also be placed directly on the chassis 11 to balance the weight generated by the tiles on the front side.

[0056] The structure of the rotating arm 2 is as follows Figure 4 , Figure 7 , Fig. 9 , Fig.10 As shown, it is hingedly assembled on the traveling frame 1, and has a vertical posture and a horizontal posture during the rotation process. The upper end of the rotating arm 2 in the vertical posture is provided with a main reversing wheel 21; the rotating arm 2 is designed as a guide rail groove structure, which is used for guiding and assembling with the lifting arm 3, and plays the role of a track. At the middle position of the rear side of the rotating arm 2, near the lower one-third, a 20mm shaft sleeve 22 is provided, which is hingedly assembled with the traveling frame 1, and the rotating arm 2 can be turned around the traveling frame 1 by 90 degrees. Specifically, a support shaft extending left and right is provided at the top of the front side of the traveling frame 1. The hinged assembly of the rotating arm 2 is realized by plugging the shaft sleeve 22 with the support shaft. The upper end can be rotated backward to a horizontal posture, and the whole body can be laid flat; it can also be flipped backward to a vertical posture. After the above-mentioned pull rope 153 extends from the electric winch 151, it passes through the traveling frame 1, goes backward and upward around the main reversing wheel 21 of the rotating arm 2, and then extends forward.

[0057] When the rotating arm 2 is in a horizontal position, the rotating arm 2 is stably supported as a whole by the hinged position and the handlebar 16 protruding from the traveling frame 1, so that the tiles can be easily applied with primer. When the rotating arm 2 is in a vertical position, the wall and floor tiles can be grasped, moved, lifted, lowered, and aligned.

[0058] In order to ensure the posture stability of the rotating arm 2 in the vertical state, a retaining lock 7 is further provided between the rotating arm 2 and the traveling frame 1. Preferably, the retaining lock 7 includes a bumper bar 71 protruding from the bottom rear side wall of the rotating arm 2, and the bumper bar 71 has a stopper opening 72. In this embodiment, the bumper bar 71 is a U-shaped bar structure, which is arranged to extend perpendicularly to the rear side of the rotating arm 2, and the space between the bumper bar 71 and the rotating arm 2 constitutes the stopper opening 72. The retaining lock 7 also includes a movable part arranged on the traveling frame 1, and an elastic part is provided between the movable part and the traveling frame 1 for applying a force to the movable part to move toward the bumper bar 71 so as to intervene in the moving path of the bumper bar 71. The bumper bar 71 squeezes the movable part and moves to the rear side of the movable part during the backward movement, so that the stopper opening 72 cooperates with the movable part along the front and rear stopper limits, and the movable part is transmission-connected with an unlocking structure for reversely pulling the movable part out of the moving path of the stopper opening 72 of the bumper bar 71.

[0059] Specifically in this embodiment, Figure 7 As shown, the unlocking structure is an unlocking rope 76 connected to the movable part, the movable part is a movable crank arm 73 rotatably mounted on the front bottom of the walking frame 1, and a receiving groove 75 is arranged on the left and right sides of the movable crank arm 73. The elastic part is a torsion spring 74 connected between the movable crank arm 73 and the walking frame 1. The unlocking rope 76 passes through the walking frame 1 and is connected to the above-mentioned driving handle 17. By swinging the driving handle 17, the locking and releasing of the unlocking rope 76 is realized to control the rotation of the movable part.

[0060] When the cam 71 is in contact with the movable crank arm 73, the movable crank arm 73 is squeezed and swung upward, thereby extending the cam 71 backward into the accommodating groove 75. After the cam 71 is out of contact with the movable crank arm 73, the torsion spring 74 drives the movable crank arm 73 to swing downward in the opposite direction, thereby inserting the movable crank arm 73 into the stopper 72. At this time, the cam 71 and the movable crank arm 73 are separated. The movable crank arm 73 cooperates with the stop limit position along the front and rear directions to lock and hold the rotating arm 2; when the rotating arm 2 needs to be swung to a horizontal posture, the worker operates the driving handle 17, swings the driving handle 17 to one side, pulls the unlocking rope 76, and the unlocking rope 76 is pulled to drive the movable crank arm 73 to overcome the force of the torsion spring 74, and swings the movable crank arm 73 upward from the stop mouth 72, releasing the stop limit position between the movable crank arm 73 and the contact rod 71, and the contact rod 71 can move freely from the accommodating groove 75, thereby realizing the unlocking of the rotating arm 2.

[0061] The lifting arm 3 is used to adjust the height of the tiles. Figures 3 to 6 , Fig.11 , Fig.12As shown, the overall cross section is a rectangular tubular structure, with several groups of guide wheels 31 arranged on the left and right sides. The guide wheels 31 are used to be inserted into the guide groove of the rotating arm 2, move up and down along the groove wall of the guide groove, and form a lifting guide rail system in combination with the rotating arm 2. The bottom of the lifting arm 3 is provided with a first auxiliary reversing wheel 32, and the top is provided with a second auxiliary reversing wheel 33. After the pull rope 153 bypasses the main reversing wheel 21, it reverses downward to bypass the first auxiliary reversing wheel 32, and then bypasses the second auxiliary reversing wheel 33 upward, and continues to extend forward. At the same time, the contraction and release of the pull rope 153 can realize the guided sliding of the relative position of the lifting arm 3 and the rotating arm 2, thereby realizing the overall lifting operation of the lifting arm 3.

[0062] In order to lock the lifting arm 3 at a certain height position relative to the rotating arm 2, a lifting buckle 9 is connected between the rotating arm 2 and the lifting arm 3. Fig. 9 As shown, it is used to fix and lock the relative position of the two; specifically, a long hole 23 is also opened on the side wall of the rotating arm 2, and a rack 24 extending along the extension direction of the rotating arm 2 is installed on one side wall of the long hole 23. The lifting buckle 9 includes a retaining block 91 rotatably mounted on the side wall of the lifting arm 3, and the positive and negative rotation directions of one end of the retaining block 91 are defined as positive rotation and reverse rotation respectively. One end of the retaining block 91 can be inserted into the rack 24 of the rotating arm 2 during the forward rotation process and block and limit the position with the rack 24 along the extension direction of the rotating arm 2. A reverse-driven unlocking spring 92 is connected between the retaining block 91 and the lifting arm 3. A retaining rope 93 that pulls the retaining block 91 to swing forward is also eccentrically connected to the retaining block 91, and the retaining handle 18 on the walking frame 1 is connected to the retaining rope 93.

[0063] When the lifting height of the lifting arm 3 needs to be fixed, the holding handle 18 is operated to swing, and the holding handle 18 gathers the holding rope 93. The holding rope 93 is pulled to rotate the holding block 91 to swing forward, and one end of the holding block 91 is inserted into the rack 24, and the rack 24 is blocked to limit the position, so that the two are relatively locked. When the lifting lock of the lifting arm 3 needs to be released, the holding handle 18 is swung in the opposite direction, and the holding handle 18 releases the holding rope 93. At this time, the unlocking spring 92 pushes the holding block 91 to swing in the opposite direction, and the limit block with the rack 24 is released. Through the design of the lifting buckle 9, the lifting arm 3 can be stopped at any height within the range.

[0064] The lowering arm 4 is used to adjust the inclination and placement angle of the tiles. Figure 4 , Figure 5 , Figure 6 , Fig.13The overall structure is a rectangular square tube, and the lower end is hingedly assembled on the lifting arm 3 so as to swing outward around the hinge axis 41 for lowering; specifically, a hinge axis 41 is provided at the lower end of the lower arm 4, and a sleeve 34 is provided on the front side of the lower end of the lifting arm 3. The hinge axis 41 and the sleeve 34 are plugged into each other to achieve hinged assembly of the two. The lower arm 4 can be flipped forward and downward around the hinge axis 41, and can also be flipped backward to a posture that fits the lifting arm 3.

[0065] A working frame 5 is also provided on the lowering arm 4. Figure 4 , Figures 13 to 15 As shown, it is assembled on the lowering arm 4, and one end of which has a connecting portion 51; a suction cup bracket 61 is also provided on the working frame 5, which is used to suck and fix the wall and floor tiles. The suction cup bracket 61 has two suction cups 6 that can be electrically self-inflated above and below, and is rotatably connected to the working frame 5 with a nut in the middle. At the same time, two thread holes 62 are provided on the upper and lower sides of the nut, and locking pins can be inserted into the thread holes 62. In order to avoid the tiles from rotating when pasting wall tiles, the thread holes 62 can be opened when laying floor tiles, so that the suction cup bracket 61 rotates around the working frame 5 to adjust the laying angle of the tiles.

[0066] Preferably, in order to facilitate the adjustment of the distance from the ground when laying tiles, a guide groove 42 extending in the same direction as the guide groove 4 is provided on the lowering arm 4, and the working frame 5 is guided and assembled in the guide groove 42. A stop block 43 cooperating with the working frame 5 to stop and limit is provided at the upper end of the guide groove 42, and the position of the lower end surface of the stop block 43 in the guide groove 42 is adjustable. Specifically, the stop block 43 is connected to the top of the guide groove 42 by a thread, and after rotation, the height of the lower end of the stop block 43 can be adjusted, thereby adjusting the height of the working frame 5 in the guide groove 42.

[0067] In order to satisfy the free up and down movement of the working frame 5 in the guide groove 42, the working frame 5 is a four-wheeled trolley. The rising height of the suction cup bracket 61 is adjusted by the stop block 43. A small hole 45 is provided on the back plate of the guide groove 42 of the lowering arm 4. In order to lock the screw hole of the four-wheeled trolley and prevent it from sliding forward and backward when laying floor tiles, an anti-collision rubber block 52 is provided under the four-wheeled trolley.

[0068] At the same time, in order to ensure the smooth movement of the working frame 5 in the guide groove 42 and ensure the pulling stability of the pull rope 153, a rope limiter 44 is provided on the top of the lowering arm 4.

[0069] In order to keep the landing arm 4 at a certain angle, such as when laying floor tiles, the landing arm 4 must be kept in a horizontal position so that the floor tiles can be laid flush with the ground. At this time, when the lifting arm 3 is raised or lowered, in order to ensure that the angle of the landing arm 4 is fixed, a rope locking mechanism 8 is provided on the lifting arm 3 to limit the extension and retraction of the pull rope 153 on the lifting arm 3 to keep the swinging posture of the landing arm 4; specifically, Figure 8As shown, the rope locking mechanism 8 includes a lock frame 81 disposed on the lifting arm 3, a lock plate 82 is movably disposed in the lock frame 81 in a direction perpendicular to the pull rope 153, the pull rope 153 passes through between the lock plate 82 and the lock frame 81, the rear side of the lock plate 82 has a limit lock tooth 83 extending in the same direction as the pull rope 153 and being relatively close to the lock plate 82 to compress the pull rope 153, and the lock plate 82 is coupled with a locking structure that drives the lock plate 82 to reciprocate. At the same time, a torsion spring 88 is connected between the lock plate 82 and the lock frame 81, and the torsion spring 88 is used to realize the movement and reset of the lock plate 82 back to the position where the pull rope 153 is located.

[0070] Specifically, a locking groove 74 with a gradually decreasing diameter is formed between the side of the locking plate 82 facing away from the limiting locking tooth 83 and the locking frame 81. The locking structure includes a locking block 85 guided and inserted into the locking groove 74. A spring 86 is connected between the locking block 85 and the locking frame 81 to apply a force to the locking block 85 to move toward the large diameter end. The locking block 85 is also connected to a locking rope 87 that drives the locking block 85 to move toward the small diameter end. The locking rope 87 is connected to the above-mentioned driving handle 17.

[0071] In order to achieve control over the pull rope 153, when in a free posture, the spring 86 pushes the locking block 85 to move upward (i.e., the large diameter end), at which time the locking rope 87 is in a released posture, and the limit lock tooth 83 of the lock plate 82 is relatively separated from the lock frame 81 in opposite directions, and the pull rope 153 moves freely up and down between the two. At this time, when the pull rope 153 is released, the pull rope 153 bypasses the main reversing wheel 21, the first auxiliary reversing wheel 32, and the second auxiliary reversing wheel 33 and is connected to the work frame 5. During the release process, the upper end of the landing arm 4 is released from the lifting and is free to swing downward, and is released at a uniform speed by the pull rope 153 and is lowered at a uniform speed. After being lowered to a set angle, the pull rope 153 is no longer released. At this time, the inclined or horizontal posture of the landing arm 4 is maintained, and when it is necessary to control the lifting to maintain the posture of the landing arm 4, the worker swings the drive handle 17 in the opposite direction to tighten the locking rope 87, and the locking rope 87 pulls the lock The stop block 85 moves toward the small diameter end of the locking groove 74. During the movement, the locking block 85 is squeezed to the locking plate 82 and moves backward, and then pushed to the limiting locking tooth 83 and the side wall of the locking frame 81 gradually fit and press, thereby locking the pull rope 153 between the locking plate 82 and the locking frame 81 to achieve the locking and fixing of the pull rope 153. At this time, the pull rope 153 continues to be gathered and released. Since the pull rope 153 is locked on the lifting arm 3, the length of the pull rope 153 between the lying arm 4 and the lifting arm 3 is fixed, and the relative posture of the two is maintained. The work of the pull rope 153 can only control the lifting and lowering of the lifting arm 3. In this way, when the lying arm 4 is lowered to any angle, it can be controlled by the rope locking mechanism 8 to keep the angle of the lying arm 4 unchanged. When laying floor tiles, the floor tiles can be arbitrarily raised or lowered at any angle, allowing workers to have more operating space when laying the plaster for the second time and adjusting the laying height of the floor tiles.

[0072] During actual operation, the device can save all handling and lifting operations during tile laying, such as workers entering the site, transporting tiles, etc. The suction cup bracket 61 can suck the tiles and move them, or the lowering arm 4 can be swung to a horizontal posture and the tiles can be forked for transportation by a forklift.

[0073] Brushing adhesive on tiles: directly use the upper and lower suction cups 6 to suck the tiles, pull the vehicle body, and after brushing the adhesive, place it in another place to dry, without manual handling.

[0074] Laying floor tiles: Use the upper and lower suction cups 6 to suck the tiles, pull the vehicle body to the bottom ash of the tiles, unlock the holding lock 7, and level the rotating arm 2 and the tiles at the same time. The scraping plane height is about 75cm, which is just suitable for workers to operate. After scraping the ash, just lift it up to a vertical state. The holding lock 7 is automatically locked. Pull the walking frame 1 to move to the ground where sand and ash are laid. Press and hold the control button 19, and the lowering arm 4 starts to swing and lowers to the position for laying floor tiles. Other leveling and compacting operations are performed by workers. If the thickness of the sand and ash on the ground is not suitable, drive the rope lock device through the driving handle 17 to lock the pull rope 153, operate the control button 19, and tighten the pull rope 153. The tiles are raised in a horizontal posture following the lifting arm 3. After stopping at the set height, drive the holding handle 18 to drive the holding rope 93 to lock the lifting buckle 9 to keep the upper and lower heights of the tiles from dropping, which is convenient for workers to re-level and then lower and lay them flat.

[0075] Wall tile paving: Figures 16 to 18 As shown, after the tiles are scraped with the base mortar, the push-pull walking frame 1 is moved to the wall with the base mortar scraped, and the pull rope 153 is controlled by the control button 19 to be tightened, and the pull rope 153 pulls the working frame 5 to rise in advance, as shown in FIG. Fig.17 As shown, after the tile is raised to the position where it fits with the stop block 43, as shown in Fig.18 As shown, the lifting continues to converge and drives the lifting arm 3 to continue to rise relative to the rotating arm 2. After rising to the tile pasting height, the walking frame 1 is pushed forward, and the lifting switch of the control button 19 is repeatedly pressed to squeeze the wall tiles up and down to achieve a state of fitting with the wall. Then the suction cup 6 is opened and the worker performs leveling and adjustment work.

[0076] Of course, in this embodiment, the holding lock 7 and the rope locking mechanism 8 are controlled by a driving handle 17. In other embodiments, different control handles may be used for control respectively.

[0077] In this embodiment, the driving mechanism is composed of a driving handle and a holding handle. Of course, in other embodiments, a separate controller can be used to control the action sequence of different motors to achieve unified control, or different driving methods can be used separately.

[0078] In other embodiments, the drive of the retaining lock 7, the locking rope mechanism 8 and the lifting buckle 9 can also be replaced by electric control, and the corresponding motors are remotely controlled by the controller to rotate, thereby driving the corresponding unlocking rope 76, locking rope 87 and retaining rope 93 to be gathered and released.

[0079] In other embodiments, the retaining lock 7 can also be designed as an electric magnetic type of electromagnet and iron sheet; the retaining lock 7 can also be designed at a hinged position or replaced by a telescopic pull rod between the rotating arm 2 and the walking frame 1.

[0080] In other embodiments, the movable part can be designed as a sliding guide bar structure to achieve limited cooperation with the contact bar 71 during the translation process.

[0081] In other embodiments, the unlocking structure may also be designed to be implemented by driving the movable parts by means of extension and retraction of an electric push rod or pushing and pulling of a drive cylinder.

[0082] In other embodiments, the rope locking mechanism 8 can be directly replaced by an electric clamp or an actuated clamp.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate but not to limit the technical solutions of the present invention, and any equivalent substitutions of the present invention and any modifications or partial substitutions that do not depart from the spirit and scope of the present invention shall be included in the scope of protection of the claims of the present invention.
