Description

Technical Field

[0001] The invention relates to the technical field of exterior wall construction, and in particular to an auxiliary device for removing exterior wall bricks of a high-rise building and a protective removal and modification construction method. Background Art

[0002] With the acceleration of urbanization, many high-rise buildings have stood for decades, and the decorative and structural materials of their exterior walls have gradually aged, especially the brick layers of the exterior walls, which are easily peeled off and cracked due to long-term exposure to the natural environment, wind, rain, sun and rain. These aging bricks not only affect the aesthetics of the building, but more importantly, they pose a serious threat to the safety of pedestrians and vehicles passing by. Especially in downtown areas with dense populations, once a brick-falling accident occurs, the consequences will be disastrous. Therefore, in order to ensure public safety and enhance the image of the city, it is particularly important to remove and update the exterior wall bricks of high-rise buildings.

[0003] Traditional demolition methods mainly rely on manual demolition, which requires construction workers to work at high altitudes. Not only is the labor intensity high, but the safety risks are also extremely high. Construction workers use cutting machines on hanging baskets from top to bottom to carry out construction work, which often causes certain damage to the main structure of the building. The wall tiles are severely damaged after demolition, and the integrity of the cut wall cannot be guaranteed, and it cannot be recycled as a renewable resource. Based on this, it is necessary to study an efficient, safe, and environmentally friendly demolition auxiliary device. Summary of the invention

The output shaft of the vertical cutting motor is transmission-connected with a connecting shaft, and the vertical cutting blades are fixedly mounted on the connecting shaft at intervals.

[0008] Furthermore, the vertical cutting blades are respectively provided with blade protection shells, and the protection shells are installed on the connecting shafts through bearings. When the connecting shafts are driven to rotate by the vertical cutting motor, the vertical cutting blades can be synchronously driven to rotate in the protection shells.

[0009] Furthermore, the transverse cutting assembly includes a transverse cutting frame, a transverse cutting motor and a transverse cutting blade. The transverse cutting frame is fixed on the movable frame and extends toward the wall. The far end of the transverse cutting frame is fixedly installed with the transverse cutting motor, whose output shaft is connected to the rotating shaft in a transmission manner. The rotating shaft extends vertically downward, and the transverse cutting blade is fixedly sleeved on the rotating shaft at intervals.

[0010] Furthermore, the tensioning assembly includes a positioning seat, a top plate, a connecting rod seat, a connecting rod and a push rod, wherein the positioning seat is arranged on the front side of the positioning frame and fixedly mounted on the positioning shaft, and connecting rod seats are evenly fixed on the positioning seat along the circumference, and each connecting rod seat extends backward along the extension direction of the positioning seat, and the front and rear ends of each connecting rod seat are symmetrically hinged with connecting rods, and the top of the connecting rod is correspondingly hinged together with the bottom of the top plate.

[0011] Furthermore, push rods are fixedly connected to the rear sides of the connecting rod seats, and limiting holes corresponding to the number of push rods are opened along the circumference of the suction cup frame. Each push rod extends backward toward the suction cup frame, and a clamp is fixed at the end of the corresponding limiting hole.

[0012] Furthermore, a transfer frame is fixedly mounted on the movable frame, and the transfer frame is provided with an opening toward the interior of the hanging basket.

[0013] The present invention also provides a method for protectively dismantling and modifying exterior wall bricks of a high-rise building, comprising the following steps: S1. Construction before the exterior wall is removed: Check each brick of the exterior wall from top to bottom to eliminate risks and reinforce them; S2. Drill holes in the wall: Drill holes in the middle of the grid wall brick unit to be cut from top to bottom to ensure that the embedding depth reaches the outside of the shear wall; S3, demolition construction; the operator lifts the hanging basket to the top of the building, aligns the vertical cutting blades on the hanging basket with the gaps of the wall tiles to be cut, and starts the vertical cutting assembly, while controlling the hanging basket to descend, so that the vertical cutting blades perform vertical cutting along the gaps of the wall tiles to form multiple vertical cutting seams; after the hanging basket is lowered to the position where the wall tiles need to be removed, the transverse cutting assembly is started, and the moving frame is pushed to move the transverse cutting blade from left to right along the brick seams for cutting; after completing the cutting of a square grid unit, the transverse cutting blade is moved to the next station, and the adsorption and grasping assembly is started at this time to align it with the grid wall tile unit to be grasped, and the driving cylinder is extended toward the preset hole so that the suction cup is tightly adsorbed on the grid wall tile unit; the driving cylinder is retracted, and the cutting unit is extracted under the action of the tensioning assembly and the suction cup, and the operator takes out the grasped masonry and places it in the transfer frame, and continues the cutting operation of the next grid unit; repeat the above steps until the entire wall tile is completely removed; S4. Garbage removal: After the operator cuts the wall, it is placed in the transfer box on the mobile rack. After the transfer box is full, the garbage in the transfer box is transported to the ground.

[0014] Furthermore, in step S3, after the wall of the hanging basket area is demolished, the crane can be driven to rise to the top surface, and after all the vertical cutting blades are moved out of the cutting seam, the crane moves to the right to carry out the demolition work of the next hanging basket area.

[0015] The beneficial effect of the above technical solution is: the high-rise building exterior wall brick removal auxiliary device provided by the present invention carries the horizontal cutting component and the vertical cutting component on the hanging basket respectively, and synchronously completes the cutting operation of the vertical cutting seam by controlling the descent of the hanging basket, and realizes the cutting operation of the horizontal cutting seam by controlling the lateral movement of the movable frame in the hanging basket. In this way, there is no need for manual repeated cutting operations through a cutting machine, and the grid cutting operation of the wall to be demolished in the hanging basket area can be completed, which greatly improves the demolition construction efficiency and reduces the safety risks during the construction process.

[0016] In the present invention, the cutting operation is coordinated with the grabbing operation. First, the vertical cutting seam of the hanging basket area is cut, and then the horizontal cutting operation is performed in the unit. Finally, the masonry cut into a grid shape is grabbed out, thereby achieving accurate cutting and efficient operation of the wall tiles.

[0017] The adsorption and grabbing assembly provided by the present invention can grab the corresponding masonry structure that forms a grid unit shape relatively intact. In addition to the pre-opened holes, it greatly ensures the integrity and accuracy of the wall brick removal, reduces damage and waste, and avoids destroying the integrity of the masonry during the manual removal process using a cutting machine, causing it to fall from a height in a scattered state, thereby reducing safety risks and reducing pollution problems during the removal process.

[0018] The present invention can accurately control the movement of the positioning shaft and the suction cup frame toward the wall through the extension and contraction of the cylinder, thereby ensuring that the suction cup can be accurately adsorbed on the outer building surface brick layer, improving the accuracy of operation, and ensuring the firmness of the suction cup during the adsorption process, avoiding damage or falling off of wall tiles due to unstable adsorption.

[0019] When the fixed seat at the front end of the positioning shaft extends into the reserved hole in the wall, the tensioning assembly begins to work, and each top plate swings under the action of the connecting rod. Since the push rod is restricted in the limiting hole on the suction cup frame, the top plate expands outward and presses tightly against the inner wall of the reserved hole, which not only provides a stable internal support for the cut grid unit, but also enhances the stability of the entire adsorption and grasping assembly during operation, preventing shaking or falling off due to external force.

[0020] As the cylinder continues to contract, the cut grid units are sucked out relatively intact under the action of the tensioning assembly and the suction cups. This not only improves the grasping efficiency, but also ensures the integrity and accuracy of the wall tiles during transportation, reduces damage and waste, and the cut wall tile units can also be recycled as renewable resources, achieving sustainable utilization of resources.

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Embodiment 1, this embodiment aims to provide a high-rise building exterior wall brick removal auxiliary device, which is mainly used for the removal of hollow brick walls and facing brick layers in some old buildings, ensuring safe construction while improving construction efficiency, and greatly ensuring the integrity of the demolished masonry and the efficiency of garbage transportation. Most of the old buildings have a hollow brick wall in addition to their shear wall structure, and a ceramic tile decorative layer outside. Now there is a phenomenon of partial detachment of the hollow brick wall and the facing brick layer. In particular, most of the buildings are located in downtown areas with dense populations and great safety hazards. Therefore, it is necessary to remove the ceramic tile layer and the hollow brick masonry. Therefore, this embodiment provides a high-rise building exterior wall brick removal auxiliary device to solve the problems of low efficiency, high safety risks and serious damage to the wall bricks after removal in the process of removing the building exterior wall bricks, and realize the precise cutting and efficient transportation of the exterior wall bricks, while ensuring the safety and environmental protection of the construction process.

[0024] like Figure 1-2 As shown, the auxiliary device for removing exterior wall bricks of high-rise buildings provided in this embodiment includes a hanging basket 1, on which a movable frame 2, a horizontal cutting component 3, a vertical cutting component 4 and an adsorption grabbing component 5 are provided, wherein a lifting ear 11 is provided on the top of the hanging basket for assembly and connection with a hoisting equipment such as a crane, and an entrance 12 is provided on the side of the hanging basket, so that construction workers can enter the hanging basket from the front or side entrance 12 of the hanging basket, so as to facilitate the construction of the building layer.

[0025] like Figure 1 and Figure 3 As shown, a plurality of groups of vertical cutting components 4 are provided at the bottom of the hanging basket. In this embodiment, each group of vertical cutting components 4 is evenly distributed at the bottom of the hanging basket. When the hanging basket is lifted by the lifting equipment and operated vertically along the building wall, each group of vertical cutting components is started at the same time so that the exterior wall tiles can be evenly cut into a plurality of rows of cutting seams as the hanging basket moves vertically downward. In actual application, the arrangement of each group of vertical cutting components corresponds to the width of the hanging basket.

[0026] Furthermore, if Figure 2 and 3 As shown, the vertical cutting assembly in this embodiment includes a fixed seat 31, a push block 32, a U-shaped frame 34, a vertical cutting blade 36 and a vertical cutting motor 37, wherein the top of the fixed seat is fixed to the bottom of the hanging basket, the push block 32 is arranged on the front side of the fixed seat, the U-shaped frame is fixedly installed on the push block 32 and faces one side of the building wall, a vertical cutting motor 37 is fixedly installed on one side of the U-shaped frame, the output shaft of the vertical cutting motor is transmission-connected with a connecting shaft 38, and the connecting shaft extends horizontally to the other side of the U-shaped frame, and vertical cutting blades 36 are fixedly sleeved on the connecting shaft in the U-shaped frame at intervals, and the two vertical cutting blades can be driven to rotate by driving the vertical cutting motor, and each group of vertical cutting blades can be made to correspond to the gap of the brick layer, so that the exterior wall of the building can be cut into multiple vertical cutting seams as the hanging basket descends.

[0027] In addition, each group of vertical cutting blades is also provided with a blade protection shell 35, and the front side of the protection shell is closely adjacent to the wall by controlling the control, so as to ensure the control of the cutting depth of each blade on the wall. In actual application, the width of the hanging basket corresponds to the arrangement of the vertical cutting blades at its bottom, and the distance between adjacent groups and the distance between the vertical cutting blades in each group is the length of a cutting unit, thereby ensuring the accuracy of the control of the cutting length.

[0028] like Figure 1 and Figure 4 As shown, a mobile frame 2 is also provided in the hanging basket, and the top and bottom of the mobile frame are respectively slidably mounted on the slide rails 13 laid in the hanging basket, so that the construction workers in the hanging basket can push the mobile frame to move back and forth horizontally inside the hanging basket, and the horizontal cutting assembly 4 is fixedly installed on the mobile frame.

[0029] join Figure 4 In this embodiment, the transverse cutting assembly includes a transverse cutting frame 41, a transverse cutting motor 42 and a transverse cutting blade 43, wherein the transverse cutting frame 41 is fixed on the mobile frame and extends toward the wall, and the far end of the transverse cutting frame is fixedly installed with a transverse cutting motor 42, whose output shaft is connected to the rotating shaft, and the rotating shaft extends vertically downward, and the transverse cutting blades are fixedly sleeved on the rotating shaft at intervals, and the distance between adjacent transverse cutting blades is the width of a cutting unit.

[0030] Each cross-cutting blade is also equipped with a protective shell, similar to the vertical cutting blade, and the protective shell on each blade is mounted on the transmission shaft through a bearing. Therefore, when the hanging basket is lowered to the specified position, the vertical cutting seams in each cutting unit have been formed. After the hanging basket is stable, each cross-cutting blade corresponds to the gap of the tile layer, and then the horizontal cutting seam can be cut by controlling the horizontal movement of the mobile frame in the hanging basket. After the cutting is completed, a gridded wall tile cutting unit is formed, and then the unit can be moved out to the transfer frame through the adsorption grabbing component.

[0031] like Figure 1 , Figure 5 and Figure 6As shown, the adsorption and grabbing assembly 5 in this embodiment includes a cylinder 51, a suction cup frame 52, a tensioning assembly 54 and a positioning shaft 55. The cylinder 51 is fixedly installed in the mounting seat 21 on the mobile frame, and the output end extends toward the wall and is fixedly mounted on the positioning shaft 55. In this embodiment, the positioning shaft is a key shaft. The suction cup frame 52 is slidably mounted on the positioning shaft. A plurality of suction cups 53 are fixed along the circumference of the suction cup frame. Each suction cup is driven by an air pump at the rear side of the suction cup frame (this is a prior art, not shown in the figure, and the air pump can be installed in the mounting seat). A limiting seat 55 is also fixedly mounted on the positioning shaft at the rear side of the positioning frame. When the limiting seat moves to contact with the rear side of the suction cup frame, it can be determined that the positioning shaft has extended to the end position in the preset hole, and at the same time, the limiting seat can press the suction cup forward so that it can be firmly adsorbed on the outer surface of the tile layer.

[0032] The tensioning assembly 54 is arranged on the positioning shaft at the front side of the suction cup frame. Figure 5 As shown, in this embodiment, the tensioning assembly includes a positioning seat 541, a top plate 542, a connecting rod seat 543, a connecting rod 544 and a push rod 545, wherein the positioning seat 541 is arranged on the front side of the positioning frame and is fixedly mounted on the positioning shaft 55, and the connecting rod seats 543 are evenly fixed along the circumference of the positioning seat 541, and each connecting rod seat extends backward along the extension direction of the positioning seat. In this embodiment, three groups of connecting rod seats are provided, and the front and rear ends of each connecting rod seat are symmetrically hinged with connecting rods 544 respectively. The top plate 542 is an arc-shaped structure, and the top of the connecting rod is correspondingly hinged to the bottom of the top plate, so that the top plates distributed circumferentially on the positioning seat can swing back and forth under the action of the corresponding connecting rods.

[0033] like Figure 5 As shown, the rear side of each group of connecting rod seats on the positioning seat 541 is fixedly connected with a push rod 545, and limiting holes 546 corresponding to the number of push rods are opened along the circumference of the suction cup frame. Each push rod extends backward toward the suction cup frame, and a clamping head is fixed on the end of the corresponding limiting hole, so that the push rod can be slidably clamped in the limiting hole.

[0034] In the present embodiment, the adsorption and grabbing assembly is arranged in this way, and the controller controls the cylinder to extend, thereby driving the positioning shaft 55, the fixing seat 541 and the suction cup frame to move synchronously toward the wall, so that the suction cup is fixedly adsorbed on the outer building face brick layer 7, and the fixing seat at the front end of the positioning shaft extends into the reserved hole of the wall; then the cylinder is controlled to extend, and at the same time, each top plate on the fixing seat swings under the action of the connecting rod, but because the rear side of the push rod is restricted in the limiting hole 546 on the suction cup frame, each top plate expands outward, and each push rod extends outward to the outermost end of the limiting hole, so that the top of each top plate is tightly pressed against the inner wall of the reserved hole, providing an internal support for the masonry, and finally continuing to drive the cylinder to slowly contract, so that the cut grid unit is relatively completely adsorbed and grabbed under the action of the tensioning assembly and each suction cup.

[0035] like Figure 1 As shown, a transfer frame 6 is fixedly installed on the mobile frame below the adsorption grabbing assembly for storing the cut and grabbed masonry. The transfer frame is provided with an opening toward the interior of the hanging basket. After the transfer frame is fully loaded, it is convenient for the construction workers in the hanging basket to transfer the stored materials in the transfer frame to the ground.

[0036] Working principle description: When the auxiliary device for removing external wall bricks of high-rise buildings provided in this embodiment is actually used, Figure 8 As shown, the hanging basket is lifted to the position of the exterior wall of the high-rise building where the wall bricks need to be removed by a lifting device (such as a crane), and the removal work of the hanging basket is controlled from top to bottom; when the hanging basket moves vertically along the wall of the building, the vertical cutting blade is made to correspond to the gap of the brick layer, each group of vertical cutting components is controlled to start synchronously, and the vertical cutting motor drives the vertical cutting blade to rotate, and the vertical cutting blade will evenly cut the exterior wall bricks into multiple rows of cutting seams; When the hanging basket is lowered to the designated position, the vertical cutting seam has been formed, and the vertical cutting blade can be controlled to stop working; at this time, the construction workers in the hanging basket will push the mobile frame to move horizontally from left to right inside the hanging basket, and at the same time, the cross-cutting blade is driven to rotate by the cross-cutting motor. The cross-cutting blade corresponds to the gap of the tile layer, and the cutting operation of the horizontal cutting seam is realized by controlling the horizontal movement of the mobile frame. After cutting a station, a gridded wall tile cutting unit is formed; After the cross-cutting blade moves to the next station, the adsorption and grabbing assembly is controlled to extract the cut wall brick unit of the previous station, that is, the cylinder is controlled to drive the positioning shaft and the suction cup frame to move toward the wall, so that the suction cup is fixedly adsorbed on the outer building surface brick layer, and at the same time, the fixing seat at the front end of the positioning shaft extends into the reserved hole in the wall; at this time, the extension of the cylinder is controlled again, and the top plates on the fixing seat swing under the action of the connecting rod, and each top plate will expand outward and press tightly against the inner wall of the reserved hole; finally, the cylinder is continued to be driven to contract slowly, so that the cut grid unit is relatively completely adsorbed and grabbed under the action of the tensioning assembly and the suction cups, and the cut and grabbed masonry will be stored in the transfer frame.

[0037] The auxiliary device for removing exterior wall tiles of high-rise buildings provided in this embodiment has a compact structure. The vertical cutting seam operation is driven by the lifting of the hanging basket, which reduces manual operation and reduces safety risks during the construction process. The cut wall tile units form a grid structure, which ensures the accuracy and integrity of the wall tile cutting and reduces damage and waste. The cut wall tile units can also be recycled as renewable resources, thereby realizing sustainable utilization of resources.

[0038] Example 2: Based on Example 1, this example further illustrates the installation structure of the vertical cutting assembly.

[0039] like Figure 3 As shown in the left figure, a screw rod 33 is fixedly installed on the rear side of the push block through a bearing, the rear end of the screw rod is threadedly connected to the fixed seat, and a hand wheel is fixedly installed on its end, so that the distance between the vertical cutting blade and the wall surface can be adjusted by turning the hand wheel, ensuring that the vertical cutting blade always maintains an appropriate cutting depth during the cutting process to avoid unnecessary damage to the shear wall; and because the wall thickness and material of the exterior wall of a high-rise building may be different, it is necessary to make adjustments according to the specific situation during the actual demolition process. By turning the hand wheel to adjust the extended length of the screw rod, it can adapt to the requirements of different wall thicknesses and materials, ensuring that the cutting process proceeds smoothly, and further improving the versatility and flexibility of the device.

[0040] Embodiment 3: Based on embodiments 1 and 2, this embodiment provides another structure of a tensioning assembly.

[0041] like Fig. 9 As shown, the tensioning assembly in this embodiment also includes a limit plate 56, a spring 57 and a telescopic rod 58, wherein the suction cup frame is fixedly mounted on the positioning shaft, the limit plate is slidably mounted on the front side of the suction cup frame, and strip-shaped limit holes corresponding to the number of push rods are opened along the circumference of the limit plate, and a telescopic rod 58 is fixedly installed between the limit plate and the suction cup frame, and a spring 57 is matched on the telescopic rod.

[0042] With such an arrangement in this embodiment, when the cylinder is extended through the controller, it can simultaneously drive the fixed seat, the limit plate and the suction cup frame to move toward the wall until the limit plate contacts the preset hole, and continue to control the positioning axis to move forward so that each suction cup is adsorbed and fixed to the exterior wall tiles. At this time, the spring is compressed, and at the same time, the limit plate is tightly pressed against the preset hole under the action of the spring, and the positioning axis also reaches the specified position in the preset hole.

[0043] After the suction cup is adsorbed and fixed to the outer wall, the cylinder is driven to retract, and the positioning shaft and the fixing seat are driven to move outward. At this time, each top plate is tensioned and expanded outward under the action of the limit holes, and as the positioning shaft is slowly retracted, it is tightly pressed in the preset movement, thereby providing an internal support for the cutting unit, and finally the cut grid wall tile unit is grabbed out.

[0044] When the suction cup is adsorbed and fixed to the outer wall, the cutting operation can be carried out smoothly without worrying about the movement or falling of the wall tiles. After the cutting is completed, the retraction of the cylinder and the tensioning of the top plate can not only ensure the stability of the cutting process, but also easily grab the cut grid wall tile unit, further improving work efficiency and convenience of operation.

[0045] Embodiment 4, based on Embodiments 1-3, this embodiment provides a method for protective demolition and modification of exterior wall tiles of a high-rise building, specifically comprising the following steps: S1. Construction before the removal of the exterior wall; including setting up closed fences in the demolition construction area to prevent the flow of people and vehicles; setting up safety protection passages in the demolition construction area to ensure the normal passage of people and vehicles; setting up safety protection scaffolding on the equipment platform at the wall demolition location, and setting up a construction platform on the equipment layer to facilitate the lifting and lowering of the hanging basket; using the hanging basket to check the wall tiles one by one from top to bottom, remove the loose tiles, and complete the risk elimination work of the wall; using the hanging basket to start reinforcement construction from top to bottom, such as Figure 7 As shown, the steel plates are arranged in a plum blossom shape with a spacing of one meter up and down and left and right, and the expansion bolts are driven into the shear wall to fix it.

[0046] S2, opening a hole in the wall; Figure 8 As shown, a hole is opened in the middle of the grid wall brick unit to be cut from top to bottom to ensure that the embedding depth reaches the outside of the shear wall; S3, demolition construction; 1) Remove the windows first and then remove the large wall, cutting along the brick seams from top to bottom on the hanging basket; 2) The operator lifts the hanging basket to the top of the building, and uses the controller to accurately adjust the position of the vertical cutting blade to align it with the gap between the wall tiles to be cut, and starts the vertical cutting assembly. At the same time, the operator controls the hanging basket to descend, so that each vertical cutting blade performs vertical cutting along the gap between the wall tiles, forming multiple vertical cutting seams; 3) After the hanging basket is lowered to the position where the wall tiles need to be removed, the vertical cutting seam cutting operation of the cutting module corresponding to the hanging basket has been completed. At this time, the transverse cutting assembly is started, and the moving frame is pushed to move the transverse cutting blade from left to right along the brick seam for cutting; 4) After a square grid unit is cut, the cross-cutting blade is moved to the next station. At this time, the suction grabbing component is started to align it with the grid wall tile unit to be grabbed, and the driving cylinder is extended toward the preset hole so that the suction cup is tightly adsorbed on the grid wall tile unit; 5) After the adsorption is stable, the cylinder is driven to retract through the controller. Due to the action of the limit hole and the top plate, the top plate will be stretched outward and tightly pressed into the preset hole, providing a stable internal support for the grid wall tile unit, and the cutting unit is extracted. The operator takes out the masonry and places it in the transfer frame; and continues the cutting operation of the next grid unit; 6) Repeat the above steps until the entire wall tile is completely removed. During the removal process, when the wall facing the hanging basket (i.e. the hanging basket area) is removed, the crane can be driven to the top surface. After all the vertical cutting blades are moved out of the cutting seam, move to the right to remove the next hanging basket area. To ensure smooth cutting, the cutting blade can be replaced after each layer is cut.

[0047] S4. Garbage removal: After the operator cuts the wall, it is transferred to the transfer frame on the mobile frame, and a crane is set up on the roof. After each pair of basket areas are cut, the basket is lifted to the top floor, and the garbage in the transfer frame is transported to the roof of the equipment layer. A truck crane is used to move the garbage to the designated stacking location on the ground.

[0048] Through the above-mentioned construction steps of this embodiment, the demolition of the exterior wall bricks of a high-rise building can be completed efficiently and safely. At the same time, the construction method also pays attention to the protection of the wall and the cleanliness of the construction environment, providing strong support for subsequent repair and reconstruction work.

[0049] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. The basic concept of the present invention is to evenly distribute the cutting blades at the bottom of the hanging basket. With the vertical movement of the hanging basket, the exterior wall tiles can be accurately cut into multiple rows of cutting seams, and a transverse cutting blade that can move laterally is arranged in the hanging basket to achieve transverse cutting of the opposite brick layer, and cooperate with the vertical cutting component to form a gridded wall tile cutting unit; after the cutting is completed, the tension expansion of the adsorption grabbing component is coordinated to achieve top pressure support on the inner wall of the reserved hole, so as to stably grab the cut wall tile unit, ensure the stability and integrity of the grabbing process, and facilitate subsequent transportation, processing and recycling. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
