Description

End plate transport mechanism for tubular pole production line
Technical field
The invention belongs to technical field of buildings, are related to a kind of end plate transport mechanism for tubular pole production line.
Background technique
Existing prefabricated pile or tubular pole are as follows in production technology:
1. the metering of concrete raw material, stirring.According to designed match ratio, by sand, stone, cement, water, additive and The fresh concrete of the low slump of 3cm~5cm is made of concrete forced mixer through accurate measurement for admixture etc., if Meter requires strength grade of concrete not less than C60 or C80.
2. offcenter squared pile end plate makes.It is almost the same with pile end board production, but the end plate shape of square pile is rectangular, and The counterbore of prestressing force main reinforcement is uniformly distributed along four side of end plate, angle.Before end plate installation, it is 1.5mm~2mm's that surrounding, which needs throat thickness, The barrette cuff that sheet metal is fabricated to.
3. carcasing.Prestressing force main reinforcement uses the steel bar for prestressed concrete of low relaxation type, needs accurate fixed-length, cuts Disconnected, heading;Spiral bar uses the low-carbon cold drawn wire of vertebra 4mm~6mm;It is rectangular according to offcenter squared pile structural reinforcement design requirement Framework of steel reinforcement is machined using dedicated square pile skeleton automatic welding.
4. installing framework of steel reinforcement.The framework of steel reinforcement made, square endplate the steel that cuff is placed in offcenter squared pile has been welded into In mold, and it is connect with deformed bar anchor plate, stretch board, tension rod etc..
5. concrete distributing.By the dosage requirement of every offcenter squared pile, fresh concrete is uniformly filled up into lower half along mold Mould, in tensioning one end some concrete of cloth as more as possible.
6. molding.Offcenter squared pile upper half punching block is hung to above lower half punching block, blending bolt fixes upper and lower two halves punching block, It is not loosened with to ensure mold in high speed centrifugation operation process and concrete not running pulp.
7. prestressed stretch-draw.Whole is carried out to the offcenter squared pile framework of steel reinforcement after molding using the stretching machine of jack type It draws, after being stretched to the 70% of reinforced steel bar strength, tension rod is fixed in steel mold with big nut.
8. centrifuging process.Band mould offcenter squared pile after above-mentioned stretch-draw anchor is hung to above centrifuge, by initial velocity, middling speed, High speed, the centrifugal speed of high speed accelerate step by step, and centrifugation time is generally 10min~18min.By being centrifuged closely knit molding work Skill keeps fresh concrete uniformly closely knit along the mold surrounding of offcenter squared pile, meanwhile, tubular pole forms a round cavity.Centrifugation terminates Afterwards, stretching end is raised, topples over the waste pulp water generated in centrifugal process.
9. primary steam curing.Band mould offcenter squared pile after centrifugal forming is hung in atmospheric steam curing pool hole, it is quiet to stop 1h~2h is to slowly warm up to 90 DEG C~100 DEG C, and 4h~8h is conserved under normal pressure, concrete strength is made to reach 40MPa or more.
10. demoulding.Band mould offcenter squared pile after primary steam curing is hung on dedicated stripping station position, is unloaded with pneumatic impact wrench Tensioning bolt and die bolt are removed, applies prestressing force to pile body, then hangs away upper mold section, stir female die, shed prestressing force Widen screw rod.Female die, anchor plate, tension rod in cleaning, and brushing release agent.It is C60 for concrete design strength grade Offcenter squared pile, the offcenter squared pile after demoulding is directly hoisted to product stockyard code heap, natural curing reaches after factory intensity i.e. It can dispatch from the factory.
11. high-pressure steaming and cultivating.The offcenter squared pile that strength grade of concrete is C80 or more is designed, it need to be by the centrifugation side after demoulding Stake enters back into autoclave and carries out high-temperature vapour maintenance, and maximum temperature is 180 DEG C~200 DEG C, saturation vapour pressure 1.0MPa, supports Time 8h~12h is protected, concrete strength is made to reach 80MPa or more.Tubular pole after high-pressure curing can directly dispatch from the factory for stake.
Wherein, in knockout course, the prior art is to shed tensioning bolt with pneumatic impact wrench, then unloads the end of tensioning Plate, end plate weight is larger, needs to be deposited at one with dedicated vehicle, is re-fed at the process of installation framework of steel reinforcement after cleaning, Namely end plate will transport back and forth, to greatly waste the production time, production efficiency is not high, is also not suitable for automated production Demand.
