The stepped shaft 22 is completely consistent with the alignment groove 40 in shape, deviation cannot occur in the correction process, namely, the movable clamping block 25 is driven to move only by moving the rotating shaft 20, when the rotating shaft 20 cannot move continuously, the main rib 15 is stretched to be in a flat state, the secondary correction operation of the correction mechanism 17 is performed when the formwork 11 rotates to a certain extent, the fact that cement exists on the periphery of the reinforcement cage is ensured, the stretched main rib 15 can be pulled at the moment, and the main rib 15 is easy to keep in a flat state after being pulled.
The working principle of the invention is as follows:
one of the formworks 11 is horizontally placed on an operation platform, an opening of the operation platform faces upwards, and a reinforcement cage is placed on the formwork 11;
the two correction mechanisms 17 are respectively arranged in the two arranging grooves, in the installation process, the positions of the steel bar frameworks are adjusted, so that the main ribs 15 of the steel bar frameworks pass through the waist-shaped holes 33, the axial positions of the steel bar frameworks are adjusted, and the two ends of the main ribs 15 pass through the waist-shaped holes 33 of the two correction mechanisms 17 for a certain length; at this time, the main rib 15 passes through the waist-shaped hole 33 and simultaneously passes through the gap between the alignment clamping block 24 and the movable clamping block 25;
injecting quantitative concrete into the mould shells 11, then buckling the other mould shells 11, and fastening the two mould shells 11 by adopting matched bolts;
after the socket on the output shaft of the electric bolt spanner is sleeved with the rotating shaft 20 by utilizing the electric bolt spanner to be matched with the rotating shaft 20, the fastening bolt on the side surface of the socket of the electric bolt spanner is propped against the key groove 39, and at the moment, the socket of the electric bolt spanner rotates to drive the rotating shaft 20 to rotate together;
referring to fig. 6, rotating shaft 20 is rotated clockwise, alignment plate 27 cannot be rotated due to the cooperation of protruding block 28 and clamping groove, fixing plate 19 is connected with alignment plate 27 through connecting rod 29, fixing plate 19 cannot be rotated, and special-shaped threaded cylinder 32 and fixing plate 19 can only slide axially and cannot rotate; so the rotation of the rotation shaft 20 only drives the control disc 18 to rotate, after the control disc 18 rotates, the position of the arc-shaped groove 38 is changed, the control pin 23 is about to change position along with the arc-shaped groove 38, but the movable clamping block 25 is restrained by the sliding groove 34, so the movable clamping block 25 only slides along the sliding groove 34 and does not rotate along with the control disc 18, and the position of the control pin 23 in the arc-shaped groove 38 is changed; the clockwise rotation of the control disc 18 causes all the movable clamping blocks 25 to diverge to the periphery, namely, the movable clamping block 25 in each chute 34 approaches to one corresponding alignment clamping block 24 until the movable clamping block 25 cannot move, and the electric bolt spanner stops;
in the above process, when the movable clamp block 25 cannot move, the movable clamp block 25 fully contacts with the side surface of the main rib 15, the main rib 15 receives the constraint of the stirrup 16 and the rigidity thereof, the position of the main rib cannot be further changed, after the two mold shells 11 are buckled, the gasket 36 contacts with the inner wall of the mounting groove, the gasket 36 cannot move, when the main rib 15 contacts with the alignment clamp block 24 during movement, the alignment clamp block 24 is pushed, the alignment spring 37 changes from a normal state to a compressed state, the alignment clamp block 24 has good contact with the main rib 15, and as the movement of the movable clamp block 25 increases, the deformation of the alignment spring 37 increases, and the alignment clamp block 24 and the main rib 15 can be clamped closer; when the movable clamping blocks 25 cannot move, the alignment clamping blocks 24 and the alignment clamping blocks 24 clamp the main ribs 15 tightly, so that the end positions of the reinforcement cages are ensured to be centered and not to be attached to the inner wall of one side of the formwork 11;
in the above process, when the rotating shaft 20 rotates clockwise, the special-shaped threaded cylinder 32 cannot rotate, the special-shaped threaded cylinder 32 and the rotating shaft 20 axially move, the rotating shaft 20 moves towards one end far away from the alignment disc 27, the rotating shaft 20 moves to drive the control disc 18 to move, the alignment groove 40 on the control disc 18 is matched with the stepped shaft 22 to drive the movable disc 26 to move together, the control pin 23 and the arc-shaped groove 38 always have good matching, the movable disc 26 slides along the connecting rod 29 when the movable disc 26 moves, when the movable clamp block 25 cannot move, the movable disc 26 also stops along the axial direction of the rotating shaft 20, and when the main rib 15 is clamped by the alignment clamp block 24 and the movable clamp block 25, the main rib 15 is axially stretched, so that the main rib 15 is as much flat as possible, and the main rib 15 and the clamp bar 16 are not contacted with the side wall of the mould shell 11 as much as possible.
Placing the mould shell 11 which is buckled and subjected to preliminary correction on a rotating frame, and driving a roller to rotate after the rotating frame is started, wherein the roller contacts with a roller ring 12 to drive the mould shell 11 to rotate; after rotating for a certain time (before the cement is not completely shaped), stopping the rotating frame;
the electric bolt spanner is utilized again, a larger sleeve is adopted to be matched with the driving nut 30, referring to fig. 6, the driving nut 30 is rotated clockwise (the rotating shaft 20 cannot rotate clockwise continuously, namely the rotating shaft 20 is stationary), the connecting plate 21 and the friction plate 31 are close to the fixed disc 19, after the friction plate 31 contacts the fixed disc 19, the driving nut 30 is rotated continuously, the rotating shaft 20 is further away from the alignment disc 27, at the moment, the rotating shaft 20 moves to drive the special-shaped threaded cylinder 32 to move together, the special-shaped threaded cylinder 32 slides with the fixed disc 19, and the special-shaped threaded cylinder 32 is not contacted with the baffle 35 any more; the movable disc 26 moves further along with the rotating shaft 20, and the alignment clamping blocks 24 and the movable clamping blocks 25 clamp the main rib 15 to be further pulled outwards, so that the main rib 15 of the steel reinforcement framework is completely horizontal at this time, that is, the belly of the steel reinforcement framework does not contact the side wall of the formwork 11;
and continuously starting the rotating frame to gradually mold the cement in the mould shell 11 under the centrifugal action to form a hollow cement pole, and curing for a certain time after the cement pole is lifted from the rotating frame to open the mould to obtain the cement pole.
The wrench is powered by a power supply or a battery, and is a tool for tightening bolts. The electric wrench is mainly divided into an impact wrench, a torsion shear wrench, a fixed torque wrench, a corner wrench, an angle wrench, a hydraulic wrench, a torque wrench and a rechargeable electric wrench.
