[0035] The self-locking unit includes two self-locking slides 119 symmetrically slidably mounted on the tamping slide 104, a spring is arranged between the self-locking slide 119 and the tamping slide 104, two self-locking short rods 127 are fixedly arranged on the self-locking slide 119, the axes of the two relatively arranged self-locking short rods 127 are on the same straight line, the self-locking short rods 127 are slidably matched with the positioning rotating seat 115, and the positioning rotating shaft 117 is symmetrically fixed with a fan-shaped strip 118, and the self-locking slide 119 is fixed with an L-shaped push plate 120, the end of the fan-shaped strip 118 is an inclined surface, and the fan-shaped strip 118 is used to push the corresponding L-shaped push plate 120 to move.

[0037] The positioning motor 116 is started to drive the positioning shaft 117 to rotate, and the two fan-shaped strips 118 rotate synchronously, that is, the ends of the two fan-shaped strips 118 are moved toward one end of the corresponding L-shaped push plate 120, so that the inclined surface of the fan-shaped strip 118 contacts the inner side of the L-shaped push plate 120, and the fan-shaped strip 118 continues to rotate. Under the action of the inclined surface of the fan-shaped strip 118, the two L-shaped push plates 120 move away from each other, that is, the two self-locking slides 119 move away from each other.

If the rammed earth plate 103 is not damaged, the above steps are performed in reverse to return the rammed earth plate 103 to the initial position, and then the soil layer is continued to be rammed.

[0057] If the surface of the rammed earth plate 103 is damaged, the replacement electric cylinder 144 is started to drive the replacement base plate 145 to move towards the direction close to the rammed earth plate 103, and then the auxiliary motor 149 is started to drive the double-headed threaded screw 146 to rotate, so that the two auxiliary slides 147 move towards each other, and finally the auxiliary slides 147 contact the two sides of the rammed earth plate 103, that is, the clamping and fixing of the rammed earth plate 103 is achieved, and then the positioning motor 116 is started to drive the positioning shaft 117 to rotate, and the torsion spring between the positioning shaft 117 and the positioning seat 115 is compressed, and under the action of the fan-shaped strip plate 136, the fan-shaped ratchet bar 135 releases the restriction on the rotation direction of the limiting ratchet 134, and then under the action of the fan-shaped rack 137, the limiting ratchet bar 131 releases The restriction on the moving direction of the limit ratchet bar 130 is released, that is, the fixation of the position of the circular slide plate 122 is released, and then the limit motor 126 is started to drive the limit screw rod 125 to rotate, so that the circular slide plate 122 moves in the direction close to the limit motor 126, that is, the limit short rod 128 is disengaged from the fan-shaped groove plate 123 and the fan-shaped inner plate 124, and then the replacement motor 142 is started to drive the replacement electric cylinder 144 to rotate, and under the action of the replacement base plate 145, the rammed earth plate 103 is rotated, and finally the fan-shaped groove plate 123 is disengaged from the fan-shaped inner plate 124, and then the replacement electric cylinder 144 is started to make the replacement base plate 145 move to the position closest to the replacement motor 142, and then the replacement motor 142 is started to make the replacement base plate 145 return to a horizontal state.

[0058] Then start the replacement motor 141 to drive the replacement swivel seat 143 to rotate, and the replacement electric cylinder 144 and the replacement base plate 145 rotate synchronously, and finally the replacement base plate 145 rotates to the position farthest from the lower surface of the frame 101, and then start the shift motor 110 to move the counterweight slide 111 to the top of the rammed earth plate 103, and then start the switching motor 153 to drive the triangular swivel seat 150 to rotate, so that the clamping unit that does not clamp the spare rammed earth plate 103 rotates to the position closest to the rammed earth plate 103, at this time, the fan-shaped transmission strip plate 156 is engaged with the transmission wheel 155 in the clamping unit, and then start the clamping motor 154 to drive the transmission wheel 155 to rotate, and then the double-headed screw Under the action of the second screw rod 152, the two L-shaped clamping plates 151 are moved to the farthest position, and then the replacement electric cylinder 144 is started to make the rammed earth plate 103 on the replacement base plate 145 move upward to the position between the two L-shaped clamping plates 151, and then the clamping motor 154 is started to make the two L-shaped clamping plates 151 move towards each other, so that the two L-shaped clamping plates 151 can clamp and fix the rammed earth plate 103.

Under the action of the sector rack 137, the transmission gear 138, and the position limiting ratchet 134, the two U-shaped slides 129 return to the farthest position, that is, at this time, the position limiting ratchet bar 131 is re-engaged with the corresponding position limiting ratchet bar 130 to form a ratchet mechanism, and then under the action of the sector strip plate 136, the sector ratchet bar 135 returns to the initial position, that is, the sector ratchet bar 135 is re-engaged with the corresponding position limiting ratchet 134 to form a ratchet mechanism. The ratchet mechanism then starts the limit motor 126 to drive the limit screw 125 to rotate, so that the circular slide 122 moves away from the limit motor 126, that is, the limit short rod 128 is engaged with the corresponding fan-shaped groove plate 123 and the fan-shaped embedded plate 124, that is, the rammed earth plate 103 and the adjustment rotating seat 115 are fixed, and the torsion spring between the adjustment rotating seat 115 and the adjustment rotating shaft 117 is completely restored, and then the adjustment rotating shaft 117 is continued to be driven to rotate, and the adjustment rotating shaft 117 and the adjustment rotating shaft 117 are connected. The swivel seat 115 rotates synchronously, and finally the adjusting swivel seat 115 rotates to a vertical downward state. At this time, the adjusting swivel seat 115 contacts the limiting bar 133 and cannot continue to rotate. The adjusting shaft 117 continues to rotate, and the torsion spring between the adjusting swivel seat 115 and the adjusting shaft 117 is compressed, and the fan-shaped strip 118 disengages from the L-shaped push plate 120, so that the adjusting shaft 117 is re-engaged with the adjusting swivel seat 115, thereby realizing the locking between the ramming slide 104 and the adjusting swivel seat 115.
