And after centrifugal forming is finished, the die clamping bolts are disassembled, so that the upper die and the lower die are separated, and the formed hollow concrete telegraph pole can be taken out.

The forming equipment which is commonly adopted at present adopts the forming equipment which consists of a group of driving wheels and a group of driven wheels, so that centrifugal forming of one concrete telegraph pole can be carried out at a time, and the efficiency is too low; and the drive mechanism is located the below drive of wire pole mould and rotates, and there is not stop gear in wire pole mould's top, therefore under the faster circumstances of centrifugal speed, wire pole mould can produce ascending trend of beating, and the top lacks stop gear and leads to wire pole mould from one end to the inhomogeneous rotation of the other end easily, influences the quality of wire pole finished product.

Based on this, the utility model patent of the bulletin number CN215038732U discloses a cement electric pole centrifuge, including centrifuge main part and set up in the damper in centrifuge main part surface, damper includes the fixing base, and the fixed surface mounting of fixing base has hydraulic telescoping rod, and hydraulic telescoping rod's top fixedly connected with rotates the seat, rotates one side rotation of seat and is connected with the connecting plate, and one side fixed mounting of connecting plate has the gyro wheel. According to the cement electric pole centrifuge, when the centrifuge main body works, the damping component is matched for use to extrude the wire pole die during rotation; the hydraulic telescopic rod can drive the roller to adapt to the use of telegraph pole moulds with various sizes and heights; when the rotary seat is matched with the connecting plate for use, the rotary seat can conveniently drive the roller to change the angle, so that the blocking of the feeding and discharging of the telegraph pole mould is avoided; one side of the rotating seat is provided with a fixing bolt which can fix the connecting plate with the roller, thereby preventing the roller from loosening when rotating.
