The invention belongs to production of track boards, and particularly relates to a pre-tensioning method
prestressed concrete track board
production line maintaining
system and application thereof. The maintaining
system comprises a steam-maintaining chamber which is arranged between working tracks matched with a mold and provided with an automatic door, a
nozzle which is arranged in the steam-maintaining chamber and connected with a constant temperature
water supply device, a temperature detection device and a
temperature control device, wherein the temperature detection device and the
temperature control device are connected with a center control device; a walking track and a transfer pulling device used for pulling a mold are arranged on the ground in the steam-maintaining chamber; thewalking track is connected with the working tracks outside the steam-maintaining chamber; the temperature and
humidity detection device comprises a
core temperature and
humidity sensor, a
surface layer temperature and
humidity sensor and an environment temperature and humidity sensor; and the
temperature control device comprises a steam supply device and an
air cooling device. The technical problems that in the prior art, maintaining measures are simplex, and existing standard requirements cannot be met are effectively solved, and the maintaining
system has the advantages that the existing standard requirements are well met, high-efficiency
assembly line production can be achieved, and
automatic control is achieved easily.
