[0014] Beneficial Effects

[0015] 1. When the device is in use, the driving component and the impact component are installed inside the installation component, so there is no need for manual holding, which reduces the labor intensity of workers, and the impact component can complete the function of cyclically impacting the wall to be demolished under the drive of the driving component, so as to achieve the destruction and demolition operation of the wall through the cyclic impact on the wall. At the same time, the device has a safety anti-no-load function, that is, when the safety block does not hit the wall in place, the impact component cannot be driven by the driving component to achieve the impact demolition operation, and the impact force of the device during wall demolition can be freely adjusted and used, which can adapt to the demolition of different types of walls, thereby improving the flexibility, adaptability and practicality of the device.

[0016] 2. The lifting seat is installed inside the fixed seat, and the lifting seat can adjust the use height through the electric push rod, so that workers do not need to operate by hand when demolishing the wall through the device, which greatly reduces the labor intensity of the workers. It can also stably and safely demolish the walls at higher positions, and it is convenient and flexible to use.

[0017] 3. When the device is demolishing a wall, after setting the fixed seat at a suitable position in the construction area, the safety block is pressed against the surface of the wall to be demolished, and then the power of the drive motor is turned on, the device can start to automatically impact the wall to realize the wall demolition operation. When the safety block is pressed against the surface of the wall to be demolished, the safety block moves toward the inside of the lifting seat and shrinks, and drives the impact block to move synchronously. After the impact block moves, it will move the blocking rod to enter the rotation track of the adaptation lever, so that when the drive motor rotates, it can drive the drive rod to rotate, and the drive rod drives the gear when it rotates. The wheel can drive the driving plate to rotate through the transmission gear plate. When the driving plate rotates, the adapting lever rotates synchronously. The adapting lever will be blocked by the toggle lever during the rotation process. Therefore, when the adapting lever is blocked by the toggle lever, the impact block can be driven to move and the impact tension spring can be lengthened to store energy through the toggle lever. As the adapting lever rotates, the adapting lever will be separated from the toggle lever. Therefore, the toggle lever can automatically reset and impact the safety block under the action of the impact tension spring. Finally, the impact force is transmitted to the wall through the safety block, so as to realize the impact demolition of the wall. The operation is convenient and the degree of automation is high.

[0018] 4. The safety block can trigger the protection function after the wall is damaged by impact and when the device is unloaded. Under the protection function, the impact component will not obtain the driving force of the driving component and produce an impact action, thereby avoiding damage to the device or injury to people. It is stable to use. When the wall is damaged by impact and the device is unloaded, the safety block extends outward under the action of the safety top spring and is in a reset state. At this time, the shifting lever will not be within the rotation range of the adaptation lever, so that the driving mechanism will only idle under the drive of the driving motor and will not trigger the impact function of the impact component. It is stable to use and extremely safe.

[0019] 5. There are two sets of driving mechanisms, and the driving rods of the two sets of driving mechanisms are connected by sprocket chain transmission. This design enables the driving motor to drive the two driving disks to reverse synchronously, so that when used in conjunction with the two toggle levers, the impact block can be stably pulled and stored energy without getting stuck, further improving the stability of the device.

[0020] 6. The impact force of the impact assembly of the device during wall demolition can be freely adjusted through the adjusting rod, so that it can adapt to the demolition operations of different types of walls. When the adjusting rod is rotated, the adjusting rod can drive the positioning rod to rotate synchronously through the synchronous groove. When the positioning rod rotates, it can drive the positioning plate to move horizontally through the rod body thread, thereby changing the initial telescopic length of the impact tension spring, that is, changing the impact force obtained by the impact tension spring when the impact block moves to the maximum distance. It has strong adaptability and convenient and flexible adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Embodiment: Please refer to Figures 1 to 12 as shown

[0040] ​​The present invention provides a wall demolition device, including an installation component 1. The installation component 1 includes a fixed seat 101, an electric push rod 102, a lifting seat 103, and an adjusting rod 104. The fixed seat 101 is fixedly installed on the ground of the construction area, and the electric push rod 102 is fixedly installed inside the fixed seat 101. The lifting seat 103 is inserted into the fixed seat 101, and the top of the push rod of the electric push rod 102 is fixedly installed at the bottom of the lifting seat 103. The lifting seat 103 is installed inside the fixed seat 101, and the lifting seat 103 can adjust the use height through the electric push rod 102. Thus, when workers demolish the wall through this device, there is no need for hand-held operation, greatly reducing the labor intensity of the workers, and the wall at a higher position can also be demolished stably and safely. The adjusting rod 104 is rotatably connected inside the lifting seat 103; a driving component, the driving component is composed of a driving mechanism 2 and a driving motor 4. The driving mechanism 2 includes a driving disk 201 and a driving rod 202. The driving disk 201 is rotatably connected inside the lifting seat 103, and the driving rod 202 is rotatably connected inside the lifting seat 103; the driving motor 4 is fixedly installed on the side of the lifting seat 103; an impact component 3, the impact component 3 includes a safety block 301, an impact block 302, a positioning rod 303, and a positioning disk 304. The safety block 301 is inserted into the lifting seat 103, and the impact block 302 is inserted into the lifting seat 103. The positioning rod 303 is rotatably connected inside the safety block 301, and the positioning disk 304 is inserted into the safety block 301. The rod body of the adjusting rod 104 passes through the inside of the impact block 302; the driving component and the impact component 3 are installed inside the installation component 1, thus eliminating the need for manual hand-holding, reducing the labor intensity of the workers, and the impact component 3 can complete the function of cyclically impacting the wall to be demolished under the drive of the driving component. Thus, through the cyclical impact on the wall, the destruction and demolition operation of the wall can be realized.

[0041] Among them, there are two groups of driving mechanisms 2, and the two groups of driving mechanisms 2 are symmetrically installed inside the lifting seat 103. The driving rods 202 of the two groups of driving mechanisms 2 are connected by a sprocket chain drive, and the rotating shaft of the driving motor 4 is in transmission connection with one end of one of the driving rods 202. This design enables the driving motor 4 to drive the two driving disks 201 to reverse synchronously. Thus, in cooperation with the two shifting levers 3021, the impact block 302 can be stably pulled to store energy, and the phenomenon of jamming will not occur, improving the stability of the device.

[0042] Wherein, a transmission gear disc 2011 is provided on the outer side of the driving disc 201, and a driving gear 2021 is provided at one end of the driving rod 202. The teeth of the transmission gear disc 2011 and the driving gear 2021 are engaged for transmission. During use, when demolishing a wall, after the fixed seat 101 is set at a suitable position in the construction area, the safety block 301 is abutted against the surface of the wall to be demolished. Then, after the power supply of the driving motor 4 is turned on, the device can start to automatically impact the wall to realize the demolition operation of the wall. When the safety block 301 abuts against the surface of the wall to be demolished, at this time, the safety block 301 moves and contracts into the interior of the lifting seat 103 and drives the impact block 302 to move synchronously. After the impact block 302 moves, the shifting lever 3021 will enter the rotation track of the adapting lever 2012. Thus, when the driving motor 4 rotates, it can drive the driving rod 202 to rotate. When the driving rod 202 rotates, the driving gear 2021 can drive the driving disc 201 to rotate through the transmission gear disc 2011. When the driving disc 201 rotates, the adapting lever 2012 rotates synchronously. An adapting lever 2012 is provided on the inner side of the driving disc 201, and two staggered and symmetrical shifting levers 3021 are provided on the side surface of the impact block 302. The shifting levers 3021 are arranged at positions deviating from the center of the driving disc 201. During the rotation of the adapting lever 2012, it will be blocked by the shifting lever 3021. An impact tension spring 3022 is provided on the side surface of the impact block 302, and both ends of the impact tension spring 3022 are fixedly connected to the side surface of the impact block 302 and the side surface of the positioning disc 304 respectively. Thus, when the adapting lever 2012 is blocked by the shifting lever 3021, it can drive the impact block 302 to move and stretch the impact tension spring 3022 to store energy through the shifting lever 3021. As the adapting lever 2012 rotates, the adapting lever 2012 will disengage from the shifting lever 3021. Thus, the shifting lever 3021 can automatically reset under the action of the impact tension spring 3022 and impact the safety block 301, and finally transmit the impact force to the wall through the safety block 301 to realize the impact demolition of the wall. The operation is convenient and the degree of automation is high.

[0043] Among them, the outside of the safety block 301 is sleeved with a safety top spring 3012, and the two ends of the safety top spring 3012 are respectively against the side of the safety block 301 and the outside of the lifting seat 103. When the safety block 301 is in the reset state, the toggle stop rod 3021 is located outside the rotation trajectory of the adaptation lever 2012. In use, the safety block 301 can trigger the protection function after the wall is damaged by impact and when the device is unloaded. Under the protection function, the impact component 3 will not obtain the driving force of the driving component and produce an impact action, thereby avoiding damage to the device or injury to people. The use is stable. When the wall is damaged by impact and the device is unloaded, the safety block 301 extends outward and is in the reset state under the action of the safety top spring 3012. At this time, the toggle stop rod 3021 will not be located within the rotation range of the adaptation lever 2012, so that the driving mechanism 2 will only idle under the drive of the driving motor 4, and will not trigger the impact function of the impact component 3. The use is stable and the safety is extremely strong.

[0044] Among them, the rod body of the positioning rod 303 is provided with a thread on the outside, and the positioning rod 303 is screwed into the inside of the positioning plate 304 through the rod body thread. In use, the impact force of the impact component 3 of the device when demolishing the wall can be freely adjusted through the adjusting rod 104, so that it can adapt to the demolition operation of different types of walls. When the adjusting rod 104 is rotated, the cross-sectional shape of the rod body at one end of the adjusting rod 104 is a regular polygon, and a synchronous groove 3031 is provided inside the positioning rod 303. The rod body of the adjusting rod 104 with a regular polygon cross-section is inserted into the inside of the synchronous groove 3031. The adjusting rod 104 can drive the positioning rod 303 to rotate synchronously through the synchronous groove 3031. When the positioning rod 303 rotates, it can drive the positioning plate 304 to move horizontally through the rod body thread, thereby changing the initial telescopic length of the impact tension spring 3022, that is, changing the impact force obtained by the impact tension spring 3022 when the impact block 302 moves to the maximum distance. It has strong adaptability and convenient and flexible adjustment.

[0045] Among them, the cross-sectional shape of the positioning disk 304 is a regular polygon, and a positioning groove 3011 is provided inside the safety block 301. The positioning disk 304 is inserted into the positioning groove 3011. During use, the positioning groove 3011 can limit the moving trajectory of the positioning disk 304, so that the positioning disk 304 will not be skewed or twisted during movement, causing the device to get stuck and fail, and the use is stable.

[0046] Specific usage and function of this embodiment: In the present invention, when demolishing a wall, the impact force of the impact assembly 3 is adjusted according to the type of wall. The impact force of the impact assembly 3 when demolishing the wall can be freely adjusted through the adjusting rod 104, so as to adapt to the demolition operation of different types of walls. When the adjusting rod 104 is rotated, the adjusting rod 104 can drive the positioning rod 303 to rotate synchronously through the synchronous groove 3031. When the positioning rod 303 rotates, it can drive the positioning plate 304 to move horizontally through the rod body thread, thereby changing the initial telescopic length of the impact tension spring 3022, that is, changing the impact obtained by the impact tension spring 3022 when the impact block 302 moves to the maximum distance. After the fixing seat 101 is set at a suitable position in the construction area, the use height of the lifting seat 103 can be adjusted by the electric push rod 102 according to the construction height, and then the safety block 301 is pressed against the surface of the wall to be demolished. Then, after the power of the driving motor 4 is turned on, the device can start to automatically impact the wall to realize the demolition operation of the wall. When the safety block 301 is pressed against the surface of the wall to be demolished, the safety block 301 moves toward the inside of the lifting seat 103 and shrinks, and drives the impact block 302 to move synchronously. After the impact block 302 moves, it will push the blocking rod 3021 to enter the rotation track of the adaptation lever 2012, so that when the driving motor 4 rotates, it can drive the driving rod 202 to rotate, and the driving When the movable rod 202 rotates, the driving gear 2021 can drive the driving disk 201 to rotate through the transmission gear plate 2011. When the driving disk 201 rotates, the adapting lever 2012 rotates synchronously. The adapting lever 2012 will be blocked by the toggle blocking lever 3021 during the rotation process. Therefore, when the adapting lever 2012 is blocked by the toggle blocking lever 3021, the toggle blocking lever 3021 can drive the impact block 302 to move and stretch the impact tension spring 3022 to store energy. As the adapting lever 2012 rotates, the adapting lever 2012 will be separated from the toggle blocking lever 3021, so that the toggle blocking lever 3021 can automatically reset and impact the safety block 301 under the action of the impact tension spring 3022, and finally the impact force is passed through The safety block 301 is transmitted to the wall through the safety block 301 to realize the impact demolition of the wall. The safety block 301 can trigger the protection function after the wall is damaged by the impact and when the device is unloaded. Under the protection function, the impact component 3 will not obtain the driving force of the driving component and produce an impact action, thereby avoiding damage to the device or injury to people. The use is stable. When the wall is damaged by the impact and the device is unloaded, the safety block 301 extends outward and is in a reset state under the action of the safety top spring 3012. At this time, the shifting lever 3021 will not be located within the rotation range of the adaptation lever 2012, so that the driving mechanism 2 will only idle under the drive of the driving motor 4, and the impact function of the impact component 3 will not be triggered.
