A disassembly base 225 of a disassembly assembly is fixedly installed on the second movable arch frame 226.

[0031] The disassembly assembly also includes a translation rod, which drives the disassembly front end seat 232 to move.

A synchronous belt 235 is sleeved on the three synchronous gears 236. A disassembly nut wrench 234 is fixedly connected to each of the two synchronous gears 236 arranged up and down.

[0032] The interior of the nut removal wrench 234 is a hexagonal groove. Depending on the shape of the screw 103 , the interior of the nut removal wrench 234 can also be other shapes. The shape of the interior of the nut removal wrench 234 corresponds to the outer shape of the screw 103 .

[0033] The translation rod includes an upper translation link 227 and a lower translation link 228, both of which are rotatably installed on the disassembly base 225, the upper translation link 227 and the lower translation link 228 are cross-arranged, the end of the lower translation link 228 is hinged to the lower link diagonal rod 237, and a lower link auxiliary rod 238 is also hinged on the upper translation link 227, and the end of the lower link auxiliary rod 238 is rotatably connected to the upper translation link 227; the lower link diagonal rod 237 is hinged to the disassembly front end seat 232; the end of the upper translation link 227 is hinged to the upper link auxiliary rod 231, and the upper link auxiliary rod 231 is hinged to the disassembly front end seat 232, one end of the upper link diagonal rod 230 is hinged to the upper link auxiliary rod 231, and the other end is hinged to the disassembly front end seat 232.

[0034] Cameras are installed on the disassembly front end seat 232 and the support seat to facilitate observation of the specific positions of the transverse steel 102 and the screws 103, and to facilitate clamping and disassembly by remote control operation.

[0035] The working principle of the present invention is as follows: the lifting head 201 is installed on a crane or a gantry, the crane or the gantry is started to move the equipment above a section of the steel group 1 that needs to be disassembled, and then the lifting cylinder 203 is started to drive the driving handle 211 and the driving gear 210 to move, the driving gear 210 drives the direct-connected racks 212 on both sides to slide, the direct-connected racks 212 drive the bidirectional racks 213 to slide, the bidirectional racks 213 drive the left pinion 206 and the right pinion 208 to rotate, the left pinion 206 drives the left clamping claw 205 to slide, the right pinion 208 drives the right clamping claw 207 to slide, and the horizontal steel 102 is clamped. After clamping, the lifting cylinder 203 stops working.

[0036] Then start the telescopic cylinders 217 on both sides, and the movable ends of the telescopic cylinders 217 extend to drive the cylinder connecting rods 218 to rotate, thereby causing the first connecting rod 219 with gears, the second connecting rod 223 with gears, and the tail connecting rod 224 to rotate, and the first pinion 221 and the second pinion 222 to mesh, and finally push the disassembly base 225 to move, bringing the disassembly base 225 close to the screws 103 at the connection between the vertical steel 101 and the horizontal steel 102.

[0037] Stop the telescopic cylinder 217, start the translation motor 229 to drive the translation lower link 228 to rotate, and under the action of a series of connecting rods such as the lower connecting rod auxiliary rod 238, the lower connecting rod diagonal rod 237, the translation upper connecting rod 227, the upper connecting rod diagonal rod 230, and the upper connecting rod auxiliary rod 231, the disassembly front end seat 232 is driven to approach the screw 103, and after moving to the front of the screw 103, the movement is stopped. At this time, the telescopic cylinder 217 can be started again to fine-tune the position of the disassembly nut wrench 234 so that the internal shape of the disassembly nut wrench 234 coincides with the screw 103, and then the disassembly nut wrench 234 is brought close to the screw 103 so that the internal shape of the disassembly nut wrench 234 is tightly attached to the screw 103.

[0038] At this time, the disassembly motor 233 can be started to drive the synchronous gear 236 to rotate. Under the action of the synchronous belt 235, the disassembly nut wrench 234 is driven to rotate to remove the screw 103 from the transverse steel 102. The disassembly nut wrenches 234 on both sides of the second movable arch frame 226 work at the same time, and the disassembly nut wrench 234 on the other side also works at the same time. When the disassembly is completed, the vibration device 214 can be started to drive the transverse steel 102 to vibrate, and the screw 103 on the transverse steel 102 that has not fallen off can be vibrated off.

[0039] After the disassembly is completed, the clamped transverse steel 102 is moved to another designated position by using a crane or a gantry, and then the above structure is reset before disassembly at the next position.

[0040] Any matters not described in the present invention are applicable to the prior art.
