Description

Technical Field

[0001] The invention relates to the technical field of precast concrete, in particular to a demoulding device and a demoulding method for building construction concrete. Background Art

[0002] Precast concrete columns are a type of concrete product produced in a factory through standardized, mechanized processing. During the casting and molding process of precast components, it is often necessary to pour concrete into a mold. After the concrete solidifies, the staff needs to separate the precast column from the mold.

[0003] A Chinese patent with application number CN202322787943.0 discloses a concrete demoulding device, which relates to the technical field of demoulding devices, and includes a table plate, the upper surface of which is fixedly connected to a pillar, the upper surface of which is provided with a pneumatic unloading assembly, the upper surface of which is fixedly connected to a side frame, the outer surface of which is fixedly connected to a folding plate, and the upper surface of the table plate is provided with a receiving assembly.

[0004] According to the above-mentioned prior art, it is found that in the concrete production process, liquid concrete is injected into the mold and waits for molding before demolding. However, the amount of concrete injected often exceeds the edge of the mold, resulting in a large amount of excess material on the surface of the mold close to the concrete. If it is not cleaned, demolding will be difficult. In addition, the aggregate composition inside the concrete is uneven, resulting in inconsistent weight of the concrete at both ends in the mold. When the mold is flipped by the driving motor so that the mold opening and the surface of the buffer table fit each other, the heavier end of the concrete will first move obliquely downward and form a conflict with the inner wall of the mold, resulting in the lighter side of the concrete also unable to fall, resulting in a situation where demolding is impossible.

[0020] A protective cover 208 is provided on the outer surface of the output end of the two electric push rods 212, and the end of the protective cover 208 away from the electric push rod 212 is interconnected with the rubber pad 207. A delivery pipe 206 is provided on one side of the rubber pad 207, and an air pump 205 is provided on the end of the delivery pipe 206 away from the rubber pad 207. A limit block 213 is provided on the outer surface of the air pump 205, and one side of the limit block 213 is interconnected with one side of the electric push rod 212. The air pump 205 is communicated with the rubber pad 207 through the delivery pipe 206. A scraper is provided on the outer surface of the rubber pad 207, and a plurality of exhaust holes are provided on the side of the rubber pad 207 facing the suction cup 209. A suction cup 209 is provided below the rubber pad 207, and the suction cup 209 and the rubber pad 207 are adapted to each other, and the suction cup 209 is away from the rubber A mold 211 is provided on one side of the pad 207. Four patch-type strain gauges for detecting stress changes in the concrete 210 are symmetrically arranged around the inner wall of the mold 211. The interior of the mold 211 is filled with concrete 210. The material of the protective cover 208 is set to rubber material. When the electric push rod 212 is in an extended state, the protective cover 208 is in a stretched state. When the air pump 205 is in a working state, the electric push rod 212 is in an extended state. The rubber pad 207 and the suction cup 209 are in contact with each other, and there is a negative pressure state between the rubber pad 207 and the suction cup 209.

When the air pump 205 is not in a working state, there is a positive pressure state between the rubber pad 207 and the suction cup 209, and the rubber pad 207 and the suction cup 209 are separated from each other. When in use, by setting the electric push rod 212 and the air pump 205, and controlling the electric push rod 212 to extend downward, the rubber pad 207 and the suction cup 209 are mutually engaged, and at the same time the air pump 205 is controlled to blow or suck air into the rubber pad 207 through the delivery pipe 206 and the exhaust hole under the rubber pad 207. Since the edge of the scraper protrudes and is arranged on the outside of the rubber pad 207, and the surface of the suction cup 209 is provided with a limiting groove with the same length and width as the scraper, and according to the mutual engagement of the limiting groove and the scraper, the surface of the scraper and the suction cup 209 is used for limiting, so as to avoid the rubber pad 207 and the suction cup 209 from falling off during the operation of the air pump 205.

[0021] The clamping assembly 3 includes a support plate 302, a drive motor 301 is provided on the surface of the support plate 302, a second telescopic rod 303 is provided at the output end of the drive motor 301, a clamping plate 305 is provided at the end of the second telescopic rod 303 away from the drive motor 301, an electric spring 304 is provided at the end of the clamping plate 305 facing the second telescopic rod 303, and the electric spring 304 is arranged on the outer surface of the telescopic rod. The number of the support plate 302, the drive motor 301, the second telescopic rod 303, the clamping plate 305 and the electric spring 304 is two, and each support plate 302, the drive motor 301, the second telescopic rod 303, the clamping plate 305 and the electric spring 304 are symmetrically arranged on the left and right sides of the housing 101.

[0022] When in use, multiple driving motors 301 are set up and the second telescopic rod 303 is controlled to rotate inside the shell 101, and then the clamping plate 305 is controlled to rotate along with the second telescopic rod 303. At the same time, during the rotation, the electric spring 304 is used to control the second telescopic rod 303 to extend, thereby achieving the purpose of angular deflection during the clamping process of the mold 211.

[0023] A first telescopic rod 106 is provided inside the buffer platform 105, and the first telescopic rod 106 is arranged between the top and the bottom of the inner wall of the buffer platform 105. A buffer spring 107 is provided on one side of the inner wall of the buffer platform 105 close to the first telescopic rod 106. The number of the first telescopic rod 106 and the buffer spring 107 are both set to two, and each first telescopic rod 106 and buffer spring 107 are symmetrically arranged inside the buffer platform 105.

[0024] When in use, by setting the first telescopic rod 106 and the buffer spring 107, when the buffer platform 105 is in a compressed state, the buffer spring 107 will be in a compressed state, and the first telescopic rod 106 will also contract. Through the cooperation of the buffer spring 107 and the second telescopic rod 303, the purpose of buffering the workpiece on the buffer platform 105 is achieved, avoiding the situation where the concrete 210 after demoulding falls onto the surface of the buffer platform 105 and is damaged.

[0025] The first electrically controlled slide rail 201 is set in the longitudinal direction, and the first electrically controlled slide rail 201 controls the first electromagnetic slider 202 to move longitudinally below the top plate 102. The second electrically controlled slide rail 203 is set in the transverse direction, and the second electrically controlled slide rail 203 controls the two second electromagnetic sliders 204 to move transversely respectively. The first electrically controlled slide rail 201 and the second electrically controlled slide rail 203 intersect and are perpendicular to each other.

[0026] When in use, the first electrically controlled slide rail 201 of the same specification is set to be longitudinal, while the second electrically controlled slide rail 203 is set to be transverse. In this way, the two electric push rods 212 are controlled to move transversely or longitudinally above the mold 211 through the sliding of the first electromagnetic slider 202 and the two second electromagnetic sliders 204. Subsequently, the rubber pad 207 and the scraper are used to clean the residual material near the edge of the concrete 210 of the mold 211. At the same time, one side of the scraper is inserted between the concrete 210 and the mold 211 to separate the concrete 210 from the mold 211.

[0027] In summary, when in use, the mold 211 is first placed above the buffer table 105, and then the first electromagnetic slider 202 is moved to the middle of the mold 211 by the first electrically controlled slide rail 201, and then the second electrically controlled slide rail 203 is used to control the two second electromagnetic sliders 204 to move the two electric push rods 212 laterally, and the scraper is used to scrape and clean the residual material at the edge of the mold 211 close to the concrete 210, and at the same time, the electric spring 304 is controlled to extend and contract frequently, so that the clamping plate 305 frequently knocks on both sides of the mold 211, so that a gap is generated between the four sides of the concrete 210 and the four sides of the mold 211 and the purpose of separation is achieved, and then the electric spring 304 is controlled to move the second telescopic rod 303 in the direction of the mold 211 The mold 211 is extended and the clamping plate 305 is used to tightly hold the two sides of the mold 211. Then, the two driving motors 301 are controlled to rotate, so that the mold 211 can be turned over under the cooperation of the second telescopic rod 303 and the driving motor 301. At the same time, the two electric push rods 212 are moved to the rear of the mold 211 by the first electric-controlled slide rail 201, and the two electric push rods 212 are controlled to extend downward, so that the rubber pad 207 and the scraper exert pressure on the surface of the buffer table 105, thereby providing space for the mold 211 to be turned over, and the mold 211 is rotated toward the direction of the buffer table 105 through the cooperation of the clamping plate 305 and the driving motor 301, until the opening surface of the mold 211 and the surface of the buffer table 105 are in contact with each other to complete the demoulding work.

[0028] It should be noted that: since the specifications of the mold 211 of the device are preset, when the first electric-controlled slide rail 201 and the second electric-controlled slide rail 203 are used to clean the residual material of the mold 211 near the concrete 210, the two electric push rods 212 move to the position between the concrete 210 and the inner wall of the mold 211 according to the parameters of the mold 211, and will not cause damage to the concrete 210.

[0029] In addition, although the first electric-controlled slide rail 201 and the second electric-controlled slide rail 203 cooperate with the two electric push rods 212 and the scraper to clean the residual materials around the mold 211 respectively, and use the electric spring 304 to cooperate with the clamping plate 305 to knock the four sides of the mold 211 so that the concrete 210 in the mold 211 is separated from the mold 211 by a gap, the aggregate composition inside the concrete 210 is uneven, resulting in inconsistent weights of the concrete 210 at both ends in the mold 211. When the mold 211 is turned over by the driving motor 301 so that the opening of the mold 211 fits the surface of the buffer platform 105, the heavier end of the concrete 210 will first move obliquely downward and form a conflict with the inner wall of the mold 211, resulting in the lighter side of the concrete 210 also unable to fall, resulting in a situation where demoulding is impossible. Based on this, this solution proposes the following adjustment plan: First, patch-type strain gauges are set around the inner wall of the mold 211 to detect the stress change between the concrete 210 and the mold 211. The patch-type strain gauges correspond to four areas, denoted as A, B, C and D. When the stress of the patch-type strain gauge changes significantly, it means that the density of the concrete 210 here is relatively high, causing the concrete 210 to conflict with the inner wall of the mold 211 here during the demolding process, resulting in a situation where demolding cannot be performed.

[0030] If the stress value of area B detected by the patch type strain gauge is higher than the preset value, it means that the composition of the concrete 210 in the mold 211 is uneven, resulting in a higher density on one side of area B, so that the weight of the concrete 210 in area B is higher than that in other areas. At the same time, the data of the patch type strain gauge continues to be higher than the preset value. At this time, the electric push rod 212 is controlled to drive the rubber pad 207 and the blade to extend downward, so that the rubber pad 207 and the blade are engaged with the suction cup 209 on the mold 211. Then, the air pump 205 is controlled to evacuate the inside of the suction cup 209 through the delivery pipe 206 and the rubber pad 207, so that the rubber pad 207 and the suction cup 209 are in a negative pressure state. At this time, the rubber pad 207 and the suction cup 209 cannot be separated. Then, the electric push rod 212 is controlled to contract, so that the heavier side of the concrete in the mold tilts upward, so that the heavier concrete 210 will A portion of the stress on the mold 211 is transferred to the lighter side. At this time, the stress condition around the concrete is detected again through the patch type strain gauge. If the stress around the concrete is uniform, the electric push rod 212 is used to frequently contract and extend to achieve the purpose of shaking the mold 211. Then, another electric push rod 212 is controlled to slide to the middle position of the mold 211 through the second electric control slide rail 203 and the second electromagnetic slider 204, and the electric push rod 212 is turned on to make the rubber pad 207 frequently hit the outer surface of the mold 211, so that the concrete 210 inside the mold 211 can be separated from the mold 211 as soon as possible. Then, the stress data of the patch type strain gauge around the mold 211 is detected. When the concrete 210 in the mold 211 is separated, the data of the patch type strain gauge is restored to 0, indicating that the concrete 210 has completed the demolding work.

[0031] If the stress data of the patch type strain gauge 214 still does not change, after one of the electric push rods 212 repeatedly pulls up the heavy side of the concrete 210, the other electric push rod 212 knocks the outer surface of the mold 211 at the middle position of the mold 211. In this state, the electric spring 304 is controlled to make the second telescopic rod 303 frequently extend and contract, and the clamping plate 305 is used to knock the outer side of the mold 211, and vibration is generated to help the electric push rod 212 to demold until the stress data of the patch type strain gauge 214 is restored to. First, the two electric push rods 212 are used to press the bottom of the mold 211 through the cooperation of the rubber pad 207 and the air pump 205. Tightly adsorbed, the two electric push rods 212 are then controlled to contract, thereby lifting the mold 211 upwards, and then the state of the concrete 210 inside the mold 211 is detected by the patch type strain gauge 214. When it is detected that the concrete 210 in the mold 211 is sliding downward, the left and right sides of the concrete 210 in the sliding state are clamped by the relatively arranged clamping plates 305 in cooperation with the two electric springs 304, and then the electric push rods 212 are controlled to lift the mold 211 upwards. During the lifting process, the electric springs 304 are used to control the clamping plates 305 to always clamp the two sides of the concrete 210 in the mold 211, thereby achieving the purpose of demoulding. Example 2

[0032] The present invention also provides a demoulding method of a demoulding device for building concrete 210, and the specific steps of using the method are as follows: S1. First, the mold 211 filled with concrete 210 is placed on the surface of the buffer table 105. Then, the adjustment component 2 cooperates with the first electric control push rod and the second electric control push rod to control the scraper 212 to clean the edge of the mold 211 close to the concrete 210 and cut and separate the excess material, thereby solving the problem that the residual material covers the gap between the mold 211 and the concrete 210 and is difficult to demould; S2, then control the clamping assembly 3 to rotate, so that the mold 211 rotates, and the opening of the mold 211 is located at the bottom, so that the concrete 210 moves out toward the opening of the mold 211 under the action of its own gravity, thereby achieving the purpose of demoulding; S3. Finally, the demoulding concrete 210 is received by the buffer platform 105 to prevent the concrete 210 from falling out of the mold 211 after demoulding and causing cracks or chipping, thereby ensuring the purpose of maintaining a good appearance of the demoulding concrete 210.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
