[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0053] Example 1:

[0054] See also Figures 1 to 13 As shown, a building demolition device of this embodiment includes a fixed shell 1 and a supporting shell 4. The supporting shell 4 is located at one end of the fixed shell 1. The four end corners of the bottom of the fixed shell 1 are fixed with braking moving wheels 2, and the movement of the fixed shell 1 can be achieved or restricted by controlling the braking moving wheels 2.

[0055] A closing door 9 is provided at the other end of the fixed shell 1 , so as to facilitate inspection and maintenance of objects inside the fixed shell 1 through the closing door 9 .

[0056] A hook 3 is fixed on the top of the fixed shell 1, and the hook 3 can be connected to a crane, so that the device can be easily moved to the height of the floor that needs to be demolished.

[0057] The support shell 4 is internally rotatably connected to a connecting column 13, and a driving mechanism for driving the connecting column 13 to rotate is also installed inside the support shell 4; the end of the connecting column 13 away from the fixed shell 1 passes through the support shell 4 and is fixed with a fixing plate 17, and both sides of the fixing plate 17 away from the end of the support shell 4 are fixed with a first connecting block 15, and the inner side of one end of the two first connecting blocks 15 is rotatably connected to the cutting blade 5, so that the cutting blade 5 can be supported by the first connecting block 15; a protective shell 16 is fixed to one side of one of the first connecting blocks 15, and a rotary drive motor is installed inside the protective shell 16, and the output end of the rotary drive motor is connected to the cutting blade 5, so that the cutting blade 5 can be driven to rotate by the rotation of the rotary drive motor.

[0058] During use, the steel rope of the crane is passed through the hook 3, so that the crane can drive the hook 3 to rise and fall through the steel rope, and the lifting of the hook 3 drives the device to rise and fall, so that the entire device can be moved to the height of the floor that needs to be demolished; then, by pushing the fixed shell 1 and braking the movement of the moving wheel 2, the fixed shell 1 can be moved to an appropriate position, and then the cutting blade 5 is driven to rotate by the rotating drive motor, and the building wall can be cut by the rotation of the cutting blade 5.

[0059] See also Figure 3 As shown, the drive mechanism includes a rotation drive motor 10, a transmission worm 11, and a transmission worm gear 12. The rotation drive motor 10 is fixed to the support housing 4. The output end of the rotation drive motor 10 is connected to the transmission worm 11. One side of the transmission worm 11 is meshedly connected to the transmission worm gear 12, and the transmission worm gear 12 is fixed to the outside of the connecting column 13. A limit mechanism for limiting the rotation angle is also installed inside the support housing 4 and outside the connecting column 13. The rotation of the transmission worm 11 can drive the connecting column 13 to rotate, thereby driving the rotation of the fixed plate 17.

[0060] When the wall needs to be cut at different angles, the driving motor 10 is rotated to drive the transmission worm 11 to rotate, and the rotation of the transmission worm 11 drives the meshing transmission worm wheel 12 to rotate, and the rotation of the transmission worm wheel 12 drives the connecting column 13 to rotate, and then the rotation of the connecting column 13 drives the fixing plate 17 to rotate, and the rotation of the fixing plate 17 drives the cutting blade 5 to rotate through the first connecting block 15.

[0061] See also Figures 4 to 6 As shown, the limiting mechanism includes a first limiting plate 14, a second limiting plate 18 and a rotating post 19. The first limiting plate 14 is provided with a first through hole inside, the first through hole is rotatably connected to the connecting post 13, and one end of the first limiting plate 14 is fixed to the supporting shell 4, so that when the connecting post 13 rotates, it will not drive the first limiting plate 14 to rotate. The first limiting plate 14 is provided with an annular slide groove inside and outside the first through hole. A limiting component is also installed inside the first limiting plate 14, and the second limiting plate 18 is provided with a second through hole inside, and the second through hole is fixed to the connecting post 13, so that the second limiting plate 18 can be driven to rotate synchronously through the rotation of the connecting post 13. The second limiting plate 18 is evenly fixed with rotating posts 19 on one end close to the first limiting plate 14, and the rotating post 19 is slidably connected to the annular slide groove, so that when the second limiting plate 18 rotates, the rotating post 19 can be driven to slide inside the annular slide groove.

[0062] In this embodiment, there are eight limit assemblies, which are used to allow the connecting column 13 to pause every forty-five degrees of rotation. In other embodiments, the number of limit assemblies can be designed according to the angle of pause required.

[0063] The limiting assembly includes a limiting column 20, a first return spring 21 and a limiting plate 22. The limiting column 20 is slidably connected to the first limiting plate 14. The limiting column 20 is close to one end of the first through hole and is located inside the first limiting plate 14 to fix the limiting plate 22, and the limiting plate 22 is slidably connected to the first limiting plate 14. The outside of the limiting column 20 and the end of the limiting plate 22 away from the first through hole are sleeved with a first return spring 21, so that the limiting column 20 can be driven to reset and move through the rebound of the first return spring 21.

[0064] When the connecting post 13 rotates, the connecting post 13 rotates to drive the second limit plate 18 to rotate, and the second limit plate 18 rotates to drive the rotating post 19 to rotate, and through the fixation of the first limit plate 14 and the support shell 4, the connecting post 13 is rotated inside the first through hole inside the first limit plate 14, and at the same time, the rotating post 19 is rotated inside the annular slide groove, so that after the rotating post 19 rotates a certain angle, it will be blocked by the corresponding limit post 20. When the rotating post 19 continues to rotate, the shape of the rotating body of the rotating post 19 can continuously squeeze the limit post 20, thereby making the limit post 20 drive the limit plate 22 to rise, and the limit plate 22 rises to squeeze the first return spring 21, so that after the rotating post 19 continues to rotate, the squeezed first return spring 21 can rebound, thereby driving the corresponding limit post 20 to reset.

[0065] See also Figure 1 、 Figure 2 、 Figure 7 and Figure 8 As shown, telescopic mechanisms for connecting to the supporting shell 4 are installed on both sides of the fixed shell 1.

[0067] The outer side of the displacement plate 8 is slidingly connected with the first limiting shell 6 and the second limiting shell 7, and the second limiting shell 7 is located at one end of the first limiting shell 6, so that the position of the displacement plate 8 after movement can be limited by the first limiting shell 6 and the second limiting shell 7; the interior of the first limiting shell 6 is fixed with a translation drive motor 27, and the output end of the translation drive motor 27 is connected with the first transmission gear 28, and the top end of the first transmission gear 28 is meshed with the second transmission gear 29, and the interior of the second transmission gear 29 is fixed with a connecting shaft 30, and the connecting shaft 30 is rotatably connected to the first limiting shell 6, and the outer side of the connecting shaft 30 and at one end of the second transmission gear 29 is fixed with a third transmission gear 31, and the bottom end of the third transmission gear 31 passes through the first limiting shell 6 and is meshed with the displacement plate 8, so that the displacement plate 8 can be driven to move by the rotation of the third transmission gear 31.

When the connecting shaft 30 rotates, it drives the third transmission gear 31 to rotate, and the rotation of the third transmission gear 31 drives the meshing displacement plate 8 to move. When the displacement plate 8 moves, it is limited by the slidingly connected first limiting shell 6 and the second limiting shell 7, and at the same time is slidably connected on the outside of the limiting rod 23, and the length of the displacement plate 8 is limited by the cooperation of the second limiting block 25 and the first limiting block 24.

An air outlet duct is fixed to the other end of the air pump 34, and one end of the air outlet duct passes through the fixed shell 1, so that the gas passing through the interior of the purification shell 32 can be discharged through the air outlet duct.

[0070] Furthermore, a purification component for filtering air is installed inside the top of the purification shell 32, and the purification component includes a positioning plate 38, a first purification plate 49, a second purification plate 50 and a third purification plate 51.
