DETAILED DESCRIPTION

[0035] The application will be described in further detail below in conjunction with the drawings and specific embodiments:

[0036] The embodiment 1 aims to provide a high-rise building outer wall brick demolition auxiliary device, which is mainly used for demolishing the hollow brick wall and the facing brick layer in some old buildings, ensures safe construction, improves construction efficiency, greatly guarantees the integrity of the demolished masonry and the garbage transportation efficiency. Most of the old buildings have a hollow brick wall outside the shear wall structure, and a ceramic tile decoration layer outside the hollow brick wall. The hollow brick wall and the facing brick layer have partially fallen off. Most of the buildings are located in the downtown area, and there are many people, which poses a great safety hazard. Therefore, it is necessary to demolish the ceramic tile layer and the hollow brick masonry. The high-rise building outer wall brick demolition auxiliary device is provided to solve the problems of low efficiency, high safety risk and serious damage of the demolished wall bricks during the demolition of the building outer wall bricks, and to realize the precise cutting and efficient transportation of the outer wall bricks, while ensuring the safety and environmental protection during the construction process.

[0037] As shown in Figures 1-2 , the high-rise building outer wall brick demolition auxiliary device comprises a hanging basket 1, a moving frame 2, a horizontal cutting assembly 3, a vertical cutting assembly 4 and an adsorption grabbing assembly 5. The top of the hanging basket is provided with an ear 11 for assembly connection with a hoisting device such as a crane. The side of the hanging basket is provided with an entrance 12, through which a construction worker can enter the hanging basket from the front or side of the hanging basket, thereby facilitating the construction of the building layer.

[0038] As shown in Figure 1 and Figure 3 , the bottom of the hanging basket is provided with a plurality of vertical cutting assemblies 4. In the embodiment, the vertical cutting assemblies 4 are evenly distributed at the bottom of the hanging basket. When the hanging basket is hoisted by the hoisting device and works vertically along the building wall, the vertical cutting assemblies are started to move downward with the hanging basket to uniformly cut the outer wall bricks into multiple cutting seams. In actual application, the arrangement of the vertical cutting assemblies corresponds to the width of the hanging basket.

[0039] Further, as shown in Figure 2 and 3 , the vertical cutting assembly in the embodiment comprises a fixed seat 31, a push block 32, a U-shaped frame 34, a vertical cutting blade 36 and a vertical cutting motor 37. The top of the fixed seat is fixed at 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 the side of the building wall. The U-shaped frame is fixedly installed with the vertical cutting motor 37 on one side. The output shaft of the vertical cutting motor is drivingly connected with a connecting shaft 38. The connecting shaft extends to the other side of the U-shaped frame in the transverse direction. The vertical cutting blades 36 are fixedly sleeved on the connecting shaft in the U-shaped frame. The two vertical cutting blades are driven to rotate by driving the vertical cutting motor, and the vertical cutting blades correspond to the gaps of the facing brick layer, so that the building outer wall can be cut into multiple vertical cutting seams as the hanging basket descends.

[0040] In addition, the vertical cutting blade is sleeved with a blade protection shell 35, and the front side of the protection shell is closely adjacent to the wall, so as to ensure the control of the cutting depth of each blade to the wall. In actual application, the width of the basket corresponds to the arrangement of the vertical cutting blade at the bottom, and the distance between adjacent groups and the distance of the vertical cutting blade in each group is the length of a cutting unit, so as to ensure the accuracy of the control of the cutting length.

[0041] As shown in Figure 1 and Figure 4 , the basket is also provided with a moving frame 2, which is sleeved on the slide rail 13 laid in the basket at the top and the bottom, so that the construction worker in the basket can push the moving frame to move reciprocally in the basket, and the transverse cutting assembly 4 is fixedly installed on the moving frame.

[0042] As shown in Figure 4 , the transverse cutting assembly includes a transverse cutting frame 41, a transverse cutting motor 42 and transverse cutting blades 43, wherein the transverse cutting frame 41 is fixed on the moving frame and extends towards the wall, the transverse cutting motor 42 is fixedly installed at the distal end of the transverse cutting frame, the output shaft of the transverse cutting motor 42 is drivingly connected to a rotating shaft, the rotating shaft extends vertically downward, and the transverse cutting blades are fixedly sleeved on the rotating shaft, and the distance between adjacent transverse cutting blades is the width of a cutting unit.

[0043] In addition, each transverse cutting blade is also sleeved with a protection shell, which is the same as the vertical cutting blade, and the protection shell on each blade is sleeved on the transmission shaft through a bearing. Therefore, when the basket is lowered to the specified position, the vertical cutting seam in each cutting unit has been formed, and after the basket is stable, the transverse cutting blades are corresponded to the gap of the tile layer, and then the transverse movement of the moving frame in the basket is controlled to realize the cutting operation of the transverse cutting seam. After cutting, a grid wall tile cutting unit is formed, and the unit is moved out to the transfer frame through the suction and grabbing assembly.

[0044] As shown in Figure 1 , Figure 5 and Figure 6As shown, the adsorption and grabbing assembly 5 in the embodiment includes a cylinder 51, a suction cup holder 52, a tensioning assembly 54 and a positioning shaft 55. The cylinder 51 is fixedly installed in the mounting seat 21 on the moving frame, and the output end thereof extends towards the wall surface and is fixedly sleeved with the positioning shaft 55. In the embodiment, the positioning shaft is a key shaft. The suction cup holder 52 is slidably sleeved on the positioning shaft. A plurality of suction cups 53 are fixedly arranged on the suction cup holder in a circumferential direction. Each suction cup is driven by a gas pump (not shown in the figure, which is a prior art) installed in the mounting seat. A limiting seat is also fixedly sleeved on the positioning shaft at the rear side of the positioning holder. When the limiting seat moves to contact the rear side of the suction cup holder, it is determined that the positioning shaft has extended to the terminal position in the preformed hole. At the same time, the limiting seat can previously press the suction cup, so that the suction cup can be firmly adsorbed on the outer surface of the tile layer.

[0045] The tensioning assembly 54 is arranged on the positioning shaft at the front side of the suction cup holder, as shown in Figure 5 In the embodiment, the tensioning assembly includes a limiting seat 541, a top plate 542, a connecting rod seat 543, a connecting rod 544 and a push rod 545. The limiting seat 541 is arranged at the front side of the positioning holder and is fixedly sleeved on the positioning shaft 55. The connecting rod seats 543 are uniformly fixed on the limiting seat 541 in a circumferential direction. Each connecting rod seat extends rearward along the extending direction of the limiting seat. In the embodiment, three groups of connecting rod seats are arranged. The front and rear ends of each connecting rod seat are respectively and symmetrically hinged with the connecting rods 544. The top plate 542 has an arc-shaped structure. The top of each connecting rod is hingedly connected with the lower portion of the top plate, so that each top plate circumferentially distributed on the limiting seat can swing forward and backward under the action of the corresponding connecting rod.

[0046] As shown in Figure 5 The rear side of each group of connecting rod seats on the limiting seat 541 is fixedly connected with the push rod 545. Limiting holes 546 corresponding to the number of push rods are formed in the circumferential direction on the suction cup holder. Each push rod extends rearward towards the suction cup holder, and the end portion of each push rod is fixedly connected with a clamping head through the corresponding limiting hole. In this way, the push rod can be slidably clamped in the limiting hole.

[0047] In the embodiment, the adsorption and grabbing assembly is controlled by the controller to control the cylinder to extend, so as to drive the positioning shaft 55, the limiting seat 541 and the suction cup holder to move synchronously towards the wall body, so that the suction cup is fixedly adsorbed on the outer building tile layer 7, and the fixing seat at the front end of the positioning shaft extends into the preformed hole of the wall body. Then, the cylinder is controlled to extend again, and at the same time, each top plate on the fixing seat swings under the action of the connecting rod. However, the rear side of each push rod is limited in the limiting hole 546 on the suction cup holder, so that each top plate expands outward, and each push rod extends outward to the outermost end of the limiting hole, so that the upper portion of each top plate is tightly pressed on the inner wall of the preformed hole, thereby providing an internal support for the block. Finally, the cylinder is continuously driven to slowly retract, so that the cut grid unit is more completely adsorbed and grabbed under the action of the tensioning assembly and the suction cups.

[0048] like Figure 1 As shown, a transfer frame 6 is also fixedly installed on the movable frame below the adsorption and gripping component. It is used to store the masonry that has been cut and gripped. The transfer frame has an opening facing the inside of the basket. After the transfer frame is full, it is convenient for the construction workers in the basket to transfer the stored material in the transfer frame to the ground.

[0049] Working principle explanation; In practical application, the auxiliary device for removing exterior wall bricks of high-rise buildings provided in this embodiment, such as Figure 8 As shown, the suspended platform is lifted to the location of the exterior wall of the high-rise building where the wall bricks need to be removed using hoisting equipment (such as a crane), and the removal work of the suspended platform is controlled from top to bottom; when the suspended platform moves vertically along the building wall, the vertical cutting blades are aligned with the gaps of the brick layer, and each set of vertical cutting components is controlled to start synchronously. The vertical cutting motor drives the vertical cutting blades to rotate, and the vertical cutting blades will evenly cut the exterior wall bricks into multiple rows of cutting seams;

[0050] Once the suspended platform is lowered to the designated position, the vertical cutting seam is formed, and the vertical cutting blade can be stopped. At this time, the construction workers inside the suspended platform will push the moving frame to move laterally from left to right inside the platform. At the same time, the horizontal cutting motor drives the horizontal cutting blade to rotate. The horizontal cutting blade corresponds to the gap of the tile layer. By controlling the lateral movement of the moving frame, the horizontal cutting seam is cut. After one station is cut, a gridded wall tile cutting unit is formed.

[0051] After the cross-cutting blade moves to the next station, the suction and gripping assembly is controlled to extract the pre-cut wall brick unit from the previous station. This involves controlling the cylinder to drive the positioning shaft and suction cup frame to move towards the wall, fixing the suction cups onto the outer building brick layer. Simultaneously, the fixing seat at the front end of the positioning shaft extends into the pre-reserved opening in the wall. Then, the cylinder is extended, and the top plates on the fixing seat swing under the action of the connecting rod, expanding outward and pressing tightly against the inner wall of the pre-reserved opening. Finally, the cylinder is driven to slowly retract, allowing the cut grid unit to be relatively completely suctioned and gripped by the tensioning assembly and suction cups. The cut and gripped brickwork is then stored in the transfer frame.

[0052] The auxiliary device for removing exterior wall bricks of high-rise buildings provided in this embodiment has a compact structure. It uses the lifting and lowering of the basket to drive the vertical cutting operation, reducing manual operation and safety risks during construction. Furthermore, the cut brick units form a grid structure, ensuring the accuracy and integrity of the brick cutting, reducing damage and waste. The cut brick units can also be recycled as renewable resources, realizing the sustainable use of resources.

[0053] Embodiment 2, on the basis of embodiment 1, the mounting structure of the vertical cutting assembly is further illustrated.

[0054] As Figure 3 As shown in the left drawing, a screw rod 33 is also 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 the end portion of the screw rod is fixedly installed with a hand wheel, so that the distance between the vertical cutting blade and the wall surface can also be adjusted by rotating the hand wheel, so as to ensure that the vertical cutting blade always maintains appropriate cutting depth during the cutting process, and avoids unnecessary damage to the shear wall body; and since the wall thickness and material of the outer wall of the high-rise building may be different, it is necessary to adjust according to the specific situation during the actual demolition process, and the extension length of the screw rod can be adjusted by rotating the hand wheel, so as to adapt to the requirements of different wall thicknesses and materials, ensure the smooth progress of the cutting process, and further improve the versatility and flexibility of the device.

[0055] Embodiment 3, on the basis of embodiments 1 and 2, another structure of the tensioning assembly is provided.

[0056] As Figure 9 shown, the tensioning assembly in this embodiment further includes a limiting plate 56, a spring 57 and a telescopic rod 58, wherein the suction cup holder is fixedly sleeved on the positioning shaft, the limiting plate is slidingly sleeved on the front side of the suction cup holder, strip-shaped limiting holes corresponding to the number of push rods are formed on the limiting plate in a circumferential direction, the telescopic rod 58 is fixedly installed between the limiting plate and the suction cup holder, and the spring 57 is matched and sleeved on the telescopic rod.

[0057] With such a setting in this embodiment, when the cylinder is controlled to extend, the fixed seat, the limiting plate and the suction cup holder can be simultaneously driven to move towards the wall body until the limiting plate contacts the preset hole, the positioning shaft is continuously controlled to move forward, so that each suction cup is adsorbed and fixed to the outer wall tile, at this time the spring is compressed, the limiting plate is tightly pressed at the preset hole under the action of the spring, and the positioning shaft also reaches the specified position in the preset hole.

[0058] After the suction cups are adsorbed and fixed to the outer wall tile, the driving cylinder is retracted, and the positioning shaft and the fixed seat are simultaneously driven to move outward, at this time each top plate is outwardly tensioned and expanded under the action of the limiting hole, and is tightly pressed in the preset hole as the positioning shaft is continuously and slowly retracted, thereby providing an internal support for the cutting unit, and finally the cut grid wall tile unit is grabbed out.

[0059] When the suction cups are adsorbed and fixed to the outer wall tile, the cutting operation can be smoothly carried out without worrying about the movement or falling of the wall tile, and after the cutting is completed, the retraction of the cylinder and the tensioning action of the top plate not only can ensure the stability during the cutting process, but also can easily grab out the cut grid wall tile unit, thereby further improving the work efficiency and the convenience of operation.

[0060] Embodiment 4, on the basis of embodiments 1-3, provides a protective demolition construction method for high-rise building outer wall bricks, specifically comprising the following steps:

[0065] 2) The operator lifts the basket above the building, accurately adjusts the position of the vertical cutting blade through the controller, aligns it with the wall brick joint to be cut, starts the vertical cutting assembly, and controls the basket to descend, so that each vertical cutting blade cuts along the wall brick joint to form multiple vertical cutting joints;

[0066] 3) After the basket is lowered to the position where the wall bricks need to be removed, the vertical cutting joint with the cutting module corresponding to the basket has been cut, at this time, the horizontal cutting assembly is started, the moving frame is pushed to make the horizontal cutting blade move and cut from left to right along the brick joint;

[0067] 4) After cutting a square grid unit, the horizontal cutting blade is moved to the next station, at this time, the suction grabbing assembly is started to align with the grid wall brick unit to be grabbed, the cylinder is driven to extend towards the pre-designed hole, and the suction cup is tightly suctioned on the grid wall brick unit;

[0068] 5) After suctioning stably, the cylinder is retracted by the controller, due to the action of the limiting hole and the top plate, the top plate will be tensioned outward and tightly pressed in the pre-designed hole, providing a stable internal support for the grid wall brick unit, and the cutting unit is extracted, the operator takes out the extracted brickwork and places it in the transfer frame; continue the cutting operation of the next grid unit;

[0069] 6) repeat the above steps until the whole wall is completely removed, and in the process of removal, when the block of wall (i.e. the basket area) facing the basket is removed, the crane can be driven to the top surface, and after all the vertical cutting blades are removed from the cutting seam, the next basket area is removed to the right. To ensure smooth cutting, the cutting blade can be replaced after each cutting layer.

[0070] S4, garbage removal; after the wall is cut by the operator, it is placed in the transfer frame, and a crane is erected on the roof. After each basket area is cut, the basket is lifted to the top layer, and the garbage in the transfer frame is transported to the equipment layer roof, and the garbage is transported to the ground by the car crane.

[0071] Through the above construction steps of the embodiment, the demolition of the high-rise building outer wall bricks can be efficiently and safely completed, and the construction method also pays attention to the protection of the wall and the cleanliness of the construction environment, which provides strong support for the subsequent repair and reconstruction work.
