Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of bridge precast maintenance, and particularly relates to an assembled bridge deck system production line steam curing device and a working method thereof. BACKGROUND
[0002] Steam curing is to artificially create certain humidity and temperature conditions to enable the freshly poured concrete to harden normally or accelerate its strength growth. The reason why the concrete can gradually harden and grow in strength is the result of cement hydration, and cement hydration requires certain temperature and humidity conditions. If the surrounding environment does not have the conditions, artificial curing of the concrete is needed. Steam curing is a key link to improve the strength and durability of the bridge precast during the manufacturing process. Generally, slow temperature rise and humidity curing are first performed, then constant temperature and humidity curing, and finally temperature drop curing, so that a precast bridge part with good quality can be obtained.
[0003] However, the traditional steam curing technology has problems such as inaccurate temperature rise rate control and condensate accumulation leading to a decrease in the surface strength of the precast part. If the surface water of the precast part cannot be cleaned in time during the temperature rise process, a weak layer or a crack may be formed on the surface of the precast part, affecting the strength of the precast part. The traditional device lacks real-time monitoring and feedback mechanism, and it is difficult to optimize the curing parameters, which affects the final quality of the precast part.

[0040] In the actual implementation process of the embodiment, the prefabricated bridge part is placed in the curing cover 201, and then the coaming 202 is driven to rotate and adhere to the curing cover 201 by the rotating motor. Then, the sealing air bag 207 is inflated to seal the curing space. Then, the steam generator 301 is started to generate steam, which is dispersed by the atomizing head 404 of the swing pipe 403 under the action of the spray pump 401 and sprayed out. Under the action of the high-temperature steam, the temperature and humidity in the curing cover 201 begin to increase, realizing temperature curing. At the same time, the adjusting screw 502 is driven to rotate under the action of the adjusting motor 501. The adjusting block 503 on the adjusting screw 502 drives the mounting plate 505 below the electric telescopic column 504 to move. In this process, the mounting plate 505 is driven downward by the electric telescopic column 504, so that the sponge sleeve 602 on the rotating pipe 623 contacts the surface of the prefabricated bridge part. In the foregoing process, the spray pump 401 moves transversely and reciprocally with the mounting plate 505 to uniformly spray the high-temperature steam in the curing cover 201. As the high-temperature steam gradually increases, the temperature in the curing cover 201 begins to rise. The temperature of the surface of the prefabricated bridge part is obviously lower than that of the high-temperature steam before curing. During the curing process, if the high-temperature steam rushes into the curing cover 201 at a relatively fast speed and a relatively large flow, the temperature in the curing cover 201 will inevitably rise at a relatively fast speed. In this case, because the surface temperature of the prefabricated bridge part is relatively low, a large amount of high-temperature steam will produce condensate water droplets on the surface of the prefabricated bridge part during the curing process. The water droplets dissolve the cement particles to form a weak layer, and the strength of the surface of the bridge prefabricated part will be greatly reduced, which may even cause cracks on the bridge prefabricated part, thereby affecting the hardening treatment effect of the bridge prefabricated part. However, in the steam curing process of the device, the sponge sleeve 602 on the rotating pipe 623 rolls on the bridge prefabricated part to absorb the condensate water droplets, thereby effectively preventing the influence of the water droplets on the bridge prefabricated part, and better ensuring the strength of the surface of the bridge prefabricated part; When the sponge cover 602 rolls to absorb water, the wiper cover 612 can wipe the water absorbed on the sponge cover 602 out, and the water wiped out from the sponge cover 602 flows into the wiper cover 612. Under the action of the driving motor 607, the transmission cam 608 can drive the rotating pipe 623 to rotate. In this process, the transmission cam 608 can drive the movable rod 609 to move every time the sponge cover 602 rotates one round. The movable rod 609 drives the valve rod 615 to move through the linkage rod 611 at the end. The valve rod 615 moves out of the drain pipe 613, and the water flows into the collecting groove 616. The water amount detector 617 detects the amount of water absorbed by the sponge cover 602 every time it rotates one round. If it is detected that the amount of water is too large, it means that the steam flow rate is large, the temperature rising rate is fast, and the water droplets generated on the surface of the prefabricated bridge part are more. However, the temperature rising rate that is too fast will also affect the hardness formation of the bridge prefabricated part. If it is detected that the amount is small, it means that the temperature rising rate is slow. Although it has little effect on the hardness of the bridge prefabricated part, it affects the efficiency of temperature curing. Therefore, after the water amount detector 617 sends the detected water amount signal to the integrated processing box 603, the integrated processing box 603 adjusts the temperature rising rate of the steam curing according to the actual detected water amount value. If the amount of water is large, the electric adjusting column 604 drives the trigger rod 605 to move, the trigger rod 605 contacts the valve switch 313 to control the corresponding throttle valve 309 to be closed, thereby reducing the number of steam supply flow guide pipes 310, which can reduce the steam supply amount per unit time and reduce the rate. At the same time, the electric adjusting column 604 drives the adjusting rod 406 to move, which can drive the rotating pipe 623 to rotate and adjust the angle of the steam flow to increase the contact time of the steam and the prefabricated bridge part. Since the steam flow time is increased, the temperature when it contacts the prefabricated bridge part is relatively low, thereby reducing the temperature rising rate. If the detected amount of water is small, the foregoing process is reversed, which can increase the temperature rising rate and ensure the efficiency of steam curing. Overall, the device can not only better clean the water droplets on the prefabricated bridge part and reduce the influence of the water droplets on the surface of the prefabricated bridge part, but also can flexibly adjust the temperature rising rate according to the detection condition to ensure the strength of the bridge prefabricated part during the temperature rising process and prevent the bridge prefabricated part from cracking to obtain a bridge prefabricated part with higher hardness and better quality. After the temperature is raised to the standard temperature, constant temperature maintenance is carried out, after the constant temperature maintenance is completed, the exhaust fan 307 is started, and the air valve 204 on the mounting piece 203 is opened, the external low-temperature gas enters the maintenance cover 201 to realize cooling, and the high-temperature steam in the maintenance cover 201 can be discharged through the heat exchanger 306, the heat exchanger 306 can absorb the residual heat in the steam, realize heat recovery, when it is needed to fill the liquid into the steam generator 301, the liquid inlet pipe 302 enters the steam generator 301 through the heat exchanger 306, the liquid can be preheated, the heat utilization rate is improved, the overall use economy of the device will be higher; at the same time, if it is found that the cooling rate is too fast under the action of the temperature sensor 206, the number of air valves 204 opened can be adjusted in time to prevent the hardness of the bridge precast piece from being affected by too fast cooling.
[0041] A working method of the assembled bridge deck system production line steam curing device, comprising the following steps: S1, the precast bridge piece is sent into the corresponding curing cover 201, then the closing assembly is closed, the closing assembly is adjusted to contact the precast bridge piece mold shell to realize sealing, then the steam curing assembly 3, the moving assembly 5 and the curing detection assembly 6 are started respectively; S2, when it is observed that the temperature sensor 206 reaches the highest curing temperature, the steam curing assembly 3, the moving assembly 5 and the curing detection assembly 6 are closed respectively, and the constant temperature maintenance stage is entered, when the constant temperature maintenance is completed, the exhaust cooling function of the closing assembly is opened, the change of the temperature sensor 206 is observed, the exhaust cooling rate of the closing assembly is adjusted, and the cooling maintenance is carried out; S3, after the cooling maintenance is completed, the closing assembly is opened, the precast bridge piece after curing is removed, and then the moisture recycled in the curing detection assembly 6 is discharged.
[0042] The working method in the embodiment includes sealing and curing, dynamic adjustment, constant temperature maintenance and controllable cooling steps, realizes efficient and accurate automatic curing, and significantly improves the quality and production efficiency of the bridge precast piece.
