Description

Technical Field

[0001] The utility model relates to the technical field of reinforced concrete segment production, and specifically relates to a rapid cooling device for producing reinforced concrete segments. Background Technique

[0002] Reinforced concrete segments are commonly used products in tunnel projects. During the production of concrete segments, a tunnel kiln production line is mainly adopted. The welded steel reinforcement cage is placed into the segment mold and then formed by pouring concrete.

[0003] The existing patent document with the publication number CN217621218U provides a forming mold for concrete segment production. In the present utility model, the draw plate can be pulled out of the inside of the chute and outside the support frame. The movable column at the bottom of the telescopic leg abuts against the scraping plate, and the scraping plate repeatedly levels the surface of the formed segment with a curved top surface. At the same time, the compression spring I inside is always in a compressed state inside the fixed column. When the draw plate is pulled out, the compression spring I restores, and the compression spring I pushes the movable column and the scraping plate to abut against the segment. Since the bottom of the movable column is a fillet structure, the movable column can move along the inside of the hinge sleeve, that is, under the reaction force of the compression spring I, the movable column can be adjusted to an angle tangent to the arc surface of the segment for scraping and leveling, and the operation is more convenient.

[0004] However, during the production of existing reinforced concrete segments, it is not convenient to quickly cool them. During the forming process of reinforced concrete segments, a large amount of heat is generated by the hydration of concrete. If effective and uniform heat dissipation is not carried out, a large temperature stress will be formed inside the reinforced concrete segments, resulting in inconsistent shrinkage on the surface and inside of the concrete, and it is very easy to generate cracks, thereby reducing the production quality of the reinforced concrete segments.

The second water pump 106 is fixedly installed at the upper end of the cooling box 103. The second heat exchange tube 107 is fixedly installed at the upper end of the second water pump 106. The second heat exchange tube 107 is located inside the upper pressing die 102. The other end of the second heat exchange tube 107 is fixedly connected to the cooling box 103. When using the die base body 101 for the production operation of reinforced concrete segments, the staff places the welded steel reinforcement cage into the die base body 101, then pours the concrete, and then performs the die closing operation between the upper pressing die 102 and the die base body 101. The first water pump 104 and the second water pump 106 work to make the coolant inside the cooling box 103 enter the first heat exchange tube 105 and the second heat exchange tube 107. The coolant inside the first heat exchange tube 105 exchanges heat with the metal heat conducting plate 203, and the coolant inside the second heat exchange tube 107 exchanges heat with the heat conducting copper plate 204. The heat-absorbed coolant flows back into the cooling box 103 under the drive of the first water pump 104 and the second water pump 106. Circulating in this way realizes the cooling of the reinforced concrete segments and accelerates the forming of the reinforced concrete segments.

[0027] The auxiliary mechanism 2 includes a support bump 201 and a placement cavity 202. The support bump 201 is fixedly installed at the lower end inside the die base body 101, and the placement cavity 202 is fixedly arranged inside the die base body 101.

The metal heat conducting plate 203 and the heat conducting copper plate 204 absorb the heat generated during the concrete forming process. The first water pump 104 and the second water pump 106 work to make the coolant inside the cooling box 103 enter the first heat exchange tube 105 and the second heat exchange tube 107. The coolant inside the first heat exchange tube 105 exchanges heat with the metal heat conducting plate 203, and the coolant inside the second heat exchange tube 107 exchanges heat with the heat conducting copper plate 204. The heat-absorbed coolant flows back into the cooling box 103 under the drive of the first water pump 104 and the second water pump 106. Circulating in this way realizes the cooling of the reinforced concrete segments, accelerates the forming of the reinforced concrete segments. The temperature sensor 207 monitors the temperature inside the cooling box 103 and uploads the data to the controller 206. When the temperature of the coolant inside the cooling box 103 is too high, the refrigeration sheet 208 works for refrigeration. At the same time, the motor 209 works to drive the driving rod 210 to rotate, and the driving rod 210 drives the stirring rod 211 to rotate, stirring the coolant inside the cooling box 103 to make its temperature more uniform and improving the cooling effect on the reinforced concrete segments.
