The base 13 mainly functions to support the whole production equipment and improve the stability of the production equipment, so that the base 13 is generally transversely arranged, and the lower end surface of the base has a large enough contact area, so that the center of the production equipment is kept between the bases 13, and the production equipment is prevented from toppling; the upright column 19 is vertically connected with the base 13, so that on one hand, the gravity center of the cylinder 17 can be positioned in the middle position, and on the other hand, under the condition of ensuring the same height, the upright column 19 uses the least material and reduces the cost; the mounting platform 15 is fixedly arranged at the upper end of the upright post 19, the upright post 19 plays a role in supporting the mounting platform 15, the cylinder 17 and the central shaft 16 which are arranged on the mounting platform 15, and the mounting platform 15 provides a mounting space for the central shaft 16; the central shaft 16 is arranged at the central position of the cylinder 17, so that the cylinder 17 can not generate eccentric force when the central shaft 16 rotates to drive the cylinder 17 to rotate, and the cylinder 17 can conveniently rotate; the supporting rods comprise a first supporting rod 23 and a second supporting rod 20, and the cylinder 17 is mainly used for winding uncured glass fibers and providing a mold for the glass fiber reinforced plastic tube; the cylinder 17 is provided with two types, namely a first cylinder block 171 and a second cylinder block 172, and the first cylinder block 171 is connected with the inclined surface of the second cylinder block 172, wherein the second cylinder block 172 is narrow in the outside and wide in the inside, and during the contraction action, the second cylinder 17 can be conveniently actuated due to the narrow outside and wide inside, and can not be clamped, but can be actuated after being extended; the first cylinder block 171 has a wide outside and a narrow inside, and during the contraction operation, the first cylinder 17 moves after the second cylinder 17 contracts because of the wide outside and the narrow inside, but moves before the second cylinder 17 extends; the central shaft 16 is connected with the first cylinder block 171 through a first support bar 23, and the central shaft 16 is connected with the second cylinder block 172 through a second support bar 20; the support rods are telescopic rods, and after the second support rod 20 contracts to drive the second cylinder block 172 to contract along the central axis 16, the first support rod 23 contracts to drive the first cylinder block 171 to contract along the central axis 16. When the glass reinforced plastic pipe is demolded and the cylinder 17 needs to be restored, the first support rod 23 extends outward to drive the first cylinder block 171 to extend outward away from the central axis 16, and the second support rod 20 extends outward to drive the second cylinder block 172 to extend outward away from the central axis 16. The support rod is generally driven by a motor or internally provided with a cylinder. The glass steel tube production equipment is of a winding type, namely glass fiber soaked with resin is wound on the cylinder 17, the cylinder 17 rotates, so that the glass fiber soaked with resin is fully paved on the surface of the cylinder 17, and then curing is carried out; the first cylinder block 171 and the second cylinder block 172 of the cylinder 17 can be contracted after the glass fiber reinforced plastic pipe is cured, so that the diameter of the cylinder 17 is changed, the cured glass fiber reinforced plastic pipe is conveniently demoulded and separated from the cylinder 17, and the stripping efficiency is greatly improved.

The outer peripheral surface of the cylinder body 17 is provided with the annular strengthening groove 18, and the strengthening groove 18 is arranged on the outer peripheral surface of the cylinder body 17, so that when the glass fiber reinforced plastic pipe is laid, a material for improving the strength can be added in the strengthening groove 18, or other strengthening materials are not added in the strengthening groove 18, the glass fiber soaked with resin is directly wound, namely, the strengthening ring is added on the inner wall of the glass fiber reinforced plastic pipe, and the strength of the glass fiber reinforced plastic pipe can be greatly improved. The strengthening grooves 18 are generally a plurality of shallow grooves, and the shallow grooves of the strengthening grooves 18 are uniformly distributed at intervals; the uniform interval distribution can improve the strength uniformity or stress uniformity of the glass fiber reinforced plastic pipe.

A rotating wheel is also arranged on the mounting platform 15 and drives the central shaft 16 to rotate; the central shaft 16 is directly connected with the motor by arranging the rotating wheel, and the main reason is that the cylinder 17 and the central shaft 16 are generally large in mass and very large in starting resistance, and the motor is directly connected, so that the motor can be burnt; and after starting, the inertia is large, and the speed of the cylinder 17 cannot be rapidly controlled. The runner is directly started during starting, and when the resistance is large and the rotating speed is differential, the runner and the central shaft 16 skid at most without burning the motor; the speed of the central shaft 16 can be controlled through the rotating wheel, and the rotating wheel only needs to rotate reversely to achieve the effect of immediate speed reduction. In general, the rotor includes a first rotor 21 and a second rotor 22, the central shaft 16 is disposed between the first rotor 21 and the second rotor 22, and the central shaft 16 abuts against the outer peripheral surfaces of the first rotor 21 and the second rotor 22. The central shaft 16 is arranged between the first rotating wheel 21 and the second rotating wheel 22, and the first rotating wheel 21 and the second rotating wheel 22 can equally divide the pressure on the central shaft 16 and disperse the resistance; at the start of operation, the first wheel 21 turns opposite to the second wheel 22; the opposite rotating speeds can ensure that the friction on the central shaft 16 is dynamic friction, so that the working efficiency is improved, and the energy consumption is reduced. The first rotating wheel 21 and the second rotating wheel 22 are electrically connected with the motor, and the motor is arranged on the upright post 19, so that the installation space of the motor can be reduced.

The lower end of the base 13 is provided with a mounting piece 12, and the mounting piece 12 is fixedly connected with the base 13. The installation sheet 12 is used for integrally fixing the production equipment, so that the production equipment is prevented from shifting in the working process, potential safety hazards are caused, or normal production is prevented from being influenced.
