Second embodiment
The embedded parts are often pre-embedded in the masonry structure in advance, when the clamping assembly 5 is pulled upwards to be separated from the masonry structure, the clamping assembly 5 cannot smoothly pull out the embedded parts from the masonry structure due to the fact that the embedded parts are clamped by the masonry structure or the friction force between the masonry structure and the embedded parts is too large, and therefore the structure of the clamping assembly 5 of the device is further improved for more efficiently pulling out the embedded parts from the masonry structure.
As shown in fig. 5 to 9, the clamping assembly 5 includes a circular arc-shaped clamping block 501 connected to the screw 102, a cavity 502 is provided inside the clamping block 501, and the cavity is connected to an external air supply system through an air inlet pipe 503; the inner surface of the clamping assembly 5 is provided with a plurality of fixed teeth 504, the number of the fixed teeth 504 on each clamping block 501 is not less than twelve, and the outer surface of each fixed tooth 504 is provided with anti-slip stripes which can increase the friction force between the fixed teeth 504 and the embedded part, so that the effect of pulling out the embedded part is improved.
An adjusting assembly 6 is arranged between the fixing teeth 504, the adjusting assembly 6 comprises an air bag 601 communicated with the cavity 502, and knocking teeth 602 are fixedly connected to the air bag 601; the adjusting screw 102 drives the two clamping blocks 501 to approach each other so that the fixing teeth 504 clamp the embedded part, and in the process that the air cylinder 303 extends to pull the embedded part upwards through the fixing teeth 504 of the clamping assembly 5, the external air supply system repeatedly inflates and evacuates air into the air bag 601 through the air inlet pipe 503 and the cavity 502, so that the air bag 601 repeatedly expands and contracts, and the knocking teeth 602 are driven to repeatedly knock the embedded part in the repeated expansion and contraction process of the air bag 601.
After the clamping assembly 5 finishes fixing the embedded part, the fixed teeth 504 are tightly fixed on the outer surface of the embedded part, when the air bag 601 expands, the air bag 601 drives the knocking teeth 602 above the air bag to move, and because the distance from the knocking teeth 602 to the circle center of the moving ring 1 is larger than the distance from other fixed teeth 504 to the circle center of the moving ring 1, the knocking teeth 602 can knock the embedded part repeatedly when the air bag 601 expands, so that the embedded part generates transverse vibration, vibration and separation are generated between the embedded part and the masonry structure, and meanwhile, the embedded part clamped by the masonry structure is pulled out more easily by matching with the upward tension of the fixed teeth 504 to the embedded part, and the disassembly efficiency of the embedded part is greatly improved.
Third embodiment
After the clamping assembly 5 finishes fixing the embedded part, the fixed teeth 504 of the clamping assembly 5 are tightly pressed on the embedded part, the clamping assembly 5 drives the embedded part to move upwards through the friction force between the fixed teeth 504 and the outer surface of the embedded part, when the friction force between the fixed teeth 504 and the outer surface of the embedded part is insufficient, a slipping phenomenon occurs between the fixed teeth 504 and the outer surface of the embedded part, so that the embedded part cannot be smoothly pulled out, and the clamping assembly 5 and the embedded part need to be fixed again due to the relative movement of slipping between the fixed teeth 504 and the embedded part, so that the operation is complex, and the dismounting efficiency of the embedded part is reduced. To address the slippage that can occur between the stationary teeth 504 and the exterior surface of the embedment, the stationary teeth 504 are further modified.
A compression spring 505 is connected to the inner side of one of the fixed teeth 504, a pressure sensor 506 is connected to the other end of the compression spring 505, and the pressure sensor 506 is embedded on the inner surface of the clamping block 501.
When the compression spring 505 is in an initial state, the distance from the fixed teeth 504 connected with the compression spring 505 to the center of the moving ring 1 is greater than the distance from the other fixed teeth 504 to the center of the moving ring 1, so that when the adjusting screw 102 drives the two clamping blocks 501 to approach each other so that the fixed teeth 504 clamp the embedded part, the compression spring 506 is compressed and extrudes the pressure sensor 506, and the pressure value measured by the pressure sensor 506 is an initial value; by selecting the stiffness coefficient of the compression spring 506, when the clamping block 501 and the embedded part move relatively, the fixed teeth 504 connected with the compression spring 505 and the embedded part are kept still, and the pressure value measured by the pressure sensor 506 is changed relative to the initial value.
Because the clamping block 501 is elastically connected with one of the fixed teeth 504 through the compression spring 505, and the other fixed teeth 504 are rigidly fixed with the clamping block 501, when the clamping block 501 slides and moves relative to the embedded part, the other fixed teeth 504 rigidly fixed with the clamping block 501 move relative to the external surface of the embedded part, while the fixed teeth 504 connected with the compression spring 505 and the embedded part remain stationary, the distance between the pressure sensor 506 and the fixed teeth 504 connected with the compression spring 505 becomes larger, a certain amount of elastic deformation is recovered by the compression spring 505, further the pressure applied to the pressure sensor 506 changes, at this time, the pressure value is transmitted into the controller, the controller compares the pressure value detected by the pressure sensor 506 with the initial value, and determines that the pressure value detected by the pressure sensor 506 changes, which indicates that the clamping block 501 slides and moves relative to the external surface of the embedded part, and then ready to take the next action.
Specifically, in order to deal with the problem of slippage of the clamping blocks 501 relative to the outer surface of the embedded part, after the adjusting screw 102 drives the two clamping blocks 501 to approach each other so that the fixed teeth 504 clamp the embedded part, the pressure value measured by the pressure sensor 506 is an initial value; in the process that the cylinder 303 extends to pull the embedded part upwards through the fixed teeth 504 of the clamping assembly 5, when the clamping block 501 and the embedded part move relatively, the fixed teeth 504 connected with the compression spring 505 and the embedded part are kept still, and when the pressure value measured by the pressure sensor 506 changes relative to the initial value, the controller judges that the clamping block 501 slips and moves relatively relative to the outer surface of the embedded part, at the moment, the controller controls the external air supply system to supply gas with higher pressure into the cavity 502 through the air inlet pipe 503 and does not suck air outwards, the external air supply system inflates the air bag 601 through the air inlet pipe 503 and the cavity 502, so that the air bag 601 expands, and the air bag 601 expands and drives the knocking teeth 602 to clamp the embedded part. All the fixed teeth 504 and the knocking teeth 602 clamp the surface of the embedded part together, so that the friction force between the clamping block 501 and the embedded part is further increased, further slipping of the outer surfaces of the clamping block 501 and the embedded part is prevented, and the effect of detaching the embedded part is improved. The anti-skid stripes are arranged on the outer surface of the knocking teeth 602, so that the friction force between the knocking teeth 602 and the surface of the embedded part can be increased when the knocking teeth 602 clamp the outer surface of the embedded part, and the clamping effect on the embedded part is improved.
In conclusion, the clamping assembly 5 is arranged, and the clamping assembly 5 is further improved, so that on one hand, when the embedded part is clamped by the masonry structure or the embedded part cannot be pulled out due to too large friction force between the masonry structure and the embedded part, an external air supply system repeatedly inflates and deflates the air bag 601 through the air inlet pipe 503 and the cavity 502, so that the air bag 601 repeatedly expands and contracts, the air bag 601 drives the knocking teeth 602 to repeatedly knock the embedded part in the repeated expansion and contraction process, so that the embedded part and the masonry structure vibrate and fall off, and meanwhile, the embedded part clamped by the masonry structure is pulled out more easily by matching with the upward tension of the fixing teeth 504 on the embedded part; on the other hand, when the clamping block 501 slips and moves relative to the outer surface of the embedded part, the pressure value measured by the pressure sensor 506 changes relative to the initial value, the external air supply system inflates the air bag 601 through the air inlet pipe 503 and the cavity 502, so that the air bag 601 expands, and the air bag 601 expands and drives the knocking teeth 602 to clamp the embedded part. All the fixed teeth 504 and the knocking teeth 602 clamp the surface of the embedded part together, so that the friction force between the clamping block 501 and the embedded part is further increased, the clamping block 501 and the outer surface of the embedded part are prevented from further slipping, and the effect of detaching the embedded part is improved. Through the operation, the dismantling efficiency of the embedded part can be greatly improved, the manual workload is reduced, and the effect is remarkable.
