In the steel bar production line, the structure of the steel bar frame is complex, the time consumption of steel bar binding is high, and in order to ensure that the steel bar binding and the operation of the main production line are synchronous, when the steel bar production line operates, a plurality of steel bar frames are bound on the steel bar production line when one main production line operates. Like this, wait for the hoisting accessory of reinforcing bar handling truss car 13 to carry out the in-process of hoist and mount, have the reinforcing bar on the bed-jig in addition to carry out the ligature, effectively practiced thrift ligature time.
After a new flow platform 17 enters the steel bar hoisting station 3 in the main assembly line, the molds on the new flow platform have completed the assembly of the end mold and the side mold 25, at this time, one of the steel bar frameworks completed by the two sets of steel bar assembly lines is hoisted into the molds from the top through the steel bar hoisting truss cars 13, the inner mold 22 is transversely inserted into the molds through the inner mold frame 9 to be fixed after the steel bar frameworks are positioned, the inner mold frame 9 is separated from the inner mold 22 after the mold assembly is completed, and the inner mold frame 9 is reset. And then the circulation platform 17 which finishes the die assembly transfers the embedded part mounting station 4 through the ferry vehicle and the transverse conveying line 15 to finish the positioning, mounting and reinforcing of the embedded part. The embedded part installation station 4 and the measurement adjusting station 5 can both carry out inspection and adjustment work before pouring, and the two stations are arranged to be matched with the operation progress of a main production line.
The transfer platform 17 is then moved to the metrology conditioning station 5 for inspection and immediate processing if any defects are present that can be ameliorated in situ. The inspected circulation platform 17 is then moved to the concreting station 6 where concreting takes place. The concrete mixing plant sends the concrete to the spreader of concrete placement station 6 through the transfer hopper that transports by the ferry-boat flatcar, and at concrete placement station 6, spreader, row formula vibrator, automatic levelling machine move in proper order and carry out cloth, vibrate and the flattening to the concrete, accomplish concrete placement.
Pouring is completed, the flowing platform 17 flows to the transverse moving area 7, the separated hydraulic transverse moving vehicle is in place, the flowing platform 17 is lifted up and then transversely transited to a preset position to descend, the flowing platform 17 is combined with the ground support wheel 16 of the corresponding steam curing conveying line again, and then the flowing platform and the ground support wheel move longitudinally to the corresponding steam curing station 8. The steam-curing station 8 is provided with a temperature and humidity adjusting system which can intelligently control the temperature and humidity gradient adjustment in the kiln, and the beam section is cured in the steam-curing station 8 in a high-temperature and high-humidity environment according to a set program.
When the cast-in-place beam formed by pouring reaches the designed form removal strength, the cast-in-place beam and the circulation platform 17 are longitudinally moved out of the steam-curing station 8 and are transited to the form removal module station 1 through the transverse moving area 7. Because the time for detaching the module is long, two module detaching stations 1 are continuously arranged on the production line to detach the module simultaneously. When the form is removed and the hoisting is carried out, firstly, the air bag in the reserved pipeline is deflated and pumped out, the inner form frame 9 moves to approach the inner form 22, the inner form 22 is loosened and pulled out after the matching connection, the bottom form trolley 19 separates the matching beam from the cast-in-place beam after the inner form 22 is separated, and the matching beam is suspended outdoors by using a large portal crane. The matching beam bottom die 24 is suspended by a truss vehicle in a workshop, the height of the matching beam bottom die is higher than that of the cast-in-place beam, then the bottom die trolley 19 lifts the cast-in-place beam bottom die 24 to separate the cast-in-place beam bottom die 24 from the bottom die bearing frame 18, the cast-in-place beam bottom die and the cast-in-place beam on the cast-in-place beam bottom die are moved to the position of the matching beam to serve as a new matching beam, and the suspended matching beam bottom.
And detecting the position error of the die assembly, finely adjusting the position of the bottom die 24 through a hydraulic system, folding the side die 25 through the side die support 26 after matching with the matching beam, then arranging an end die, and connecting the fixed end die with the side die support 26 to complete the primary die assembly. And then the die lacking the inner die 22 after die assembly is transferred to the steel bar hoisting station 3 along with the transfer platform 17 to carry out the next procedure, so that the circular operation of the production line is realized.
The reinforcing bar assembly line that goes on simultaneously with main assembly line in this scheme to the binding of two sets of framework of steel reinforcement is carried out in step to the assembly line mode, with two module removal module stations 1 cooperations, realizes framework of steel reinforcement binding and the synchronous operation of removing the module, once accomplishes two sets ofly. The hoisting and final die assembly of the steel reinforcement framework can be completed in a short time only by the steel reinforcement hoisting station 3 of one station, so that the two groups of dies can be completed quickly, the time for completing the installation and the inspection of the embedded part installation station 4 and the measurement adjusting station 5 is short, and the embedded parts of the two groups of dies can be inspected before pouring at the embedded part installation station 4 and the measurement adjusting station 5 after the embedded parts of the two groups of dies are continuously installed. The assembly line can thus be used for two-in-one continuous pre-cast section beam assembly and pre-cast preparation. And finally, the concrete pouring and the maintenance are long, the concrete pouring is carried out one by one, the cast-in-place beam is sent to a steam-curing station 8 after the cast-in-place beam is poured, the maintenance of a plurality of cast-in-place beams is carried out through a plurality of steam-curing stations 8, and the cast-in-place beam is transferred to a formwork removing and assembling station 1 for formwork removing and assembling after the maintenance is finished. Therefore, the continuous connection can be realized by well matching different consumed time of each station in the production line, and the production efficiency is improved.
The invention is described above with reference to the accompanying drawings, it is obvious that the specific implementation of the invention is not limited by the above-mentioned manner, and it is within the scope of the invention to adopt various insubstantial modifications of the inventive concept and solution of the invention, or to apply the inventive concept and solution directly to other applications without modification.
