Description

Technical Field

[0001] This invention relates to the field of counterweight production technology, specifically to a casting process for counterweights used in new energy gravity storage. Background Technology

[0002] Currently, a new technology called gravity energy storage has emerged in the energy storage industry. Gravity energy storage involves converting and storing surplus electrical energy as the potential energy of a heavy object by lifting it. A gravity energy storage tower is a structure that uses a crane to stack concrete blocks into a tower, storing and releasing energy through the lifting and lowering of these blocks. A single concrete counterweight block can have a volume exceeding tens of cubic meters and a weight of tens of tons. A single gravity energy storage project requires thousands or even tens of thousands of counterweight blocks. Therefore, how to efficiently and cost-effectively produce such a large number of counterweight blocks has become a pressing technical challenge for gravity energy storage projects. The core technologies for counterweight block casting are formwork assembly technology and casting process. Therefore, to solve this technical challenge, it is necessary to find a highly efficient and low-cost formwork assembly technology and casting process to achieve large-scale, efficient, and low-cost casting of counterweight blocks.

[0003] Existing concrete pouring formwork mostly uses traditional loose-fitting wooden formwork or assembled metal formwork; loose-fitting wooden formwork is mainly composed of plywood, main ribs, secondary ribs, tie bolts, etc.; metal formwork is mainly steel formwork and aluminum formwork.

[0004] Chinese Patent CN210563398U discloses a "Formwork System for Concrete Pouring," specifically disclosing a formwork unit comprising a first plywood and a second plywood. A first square timber vertical rib is installed on the outer surface of the first plywood, and a second square timber vertical rib is installed on the outer surface of the second plywood. The side of the second plywood overlaps the inner surface of the first plywood. The side of the first plywood extends outward to be flush with the second square timber vertical rib installed on the outer surface of the second plywood. The outermost second square timber vertical rib installed on the outer surface of the second plywood is connected to the first plywood via a first fastening structure. This invention, by using plywood with a density lower than that of steel formwork, allows for the use of larger-sized plywood during formwork assembly without the need for additional large lifting machinery. This reduces the number and length of formwork joints, improving assembly efficiency and ensuring the quality of the poured concrete. However, the invention still has the following drawbacks: 1) Traditional concrete wooden formwork assembly technology has a relatively complex structure design in order to prevent the formwork from deforming. The number of supporting structures such as wooden vertical beams and bolts is relatively large, resulting in high material costs, high labor assembly costs, and low formwork assembly efficiency; 2) If it is used to produce gravity energy storage counterweights, additional supporting structures need to be set on the four sides of the formwork to prevent the formwork from tipping over. The assembly efficiency is low, and the total construction cost is relatively high.

[0005] Chinese Patent CN113802831A discloses a "concrete pouring template," specifically comprising a panel, a frame, vertical ribs, and horizontal ribs. The frame surrounds the perimeter of the panel and protrudes towards the back of the panel. The vertical ribs are located on the back of the panel and extend along its length. The horizontal ribs are located on the back of the panel and are perpendicular to the vertical ribs. This invention's concrete pouring template design strengthens the vertical and horizontal ribs and features an irregularly shaped frame, improving overall rigidity and bending strength, making the concrete pouring template less prone to deformation. The integrated pin design makes disassembly and assembly of the concrete pouring template more convenient, efficient, and less prone to pin loss during actual use. The use of stainless steel material reduces the weight of the concrete pouring template. However, the invention also has the following drawbacks: 1) The metal formwork for concrete pouring has many advantages, but it also has disadvantages such as complex structure, many metal reinforcing ribs, large weight, and high formwork cost. In addition, it requires the use of a crane for hoisting during on-site assembly; 2) If it is used to produce gravity energy storage counterweights, the four sides of the formwork need to be supported to prevent the formwork from tipping over, resulting in low assembly efficiency and high on-site construction costs.

[0006] In summary, existing concrete formwork assembly technology and pouring processes are no longer sufficient to meet the production requirements of emerging gravity storage counterweights. Therefore, developing a highly efficient and low-cost formwork assembly technology and pouring process to achieve large-scale, efficient, and low-cost pouring of counterweights has become an urgent problem to be solved. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a casting process for counterweight blocks for new energy gravity energy storage. Through reasonable structural design, the casting template structure is simplified, the template assembly efficiency is improved, the template processing and assembly costs are reduced, and the casting process is optimized. Thus, large-scale, high-efficiency, and low-cost casting of counterweight blocks for gravity energy storage can be achieved, meeting the requirements for mass production of counterweight blocks for gravity energy storage projects.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The innovative aspect of the present invention's casting process for counterweight blocks used in new energy gravity storage lies in including the following steps:

[0009] (1) Assembly of mold box: First, lay out the line and measure, assemble and place the base frame, then place the base plate horizontally in the middle of the upper surface of the base frame, and then assemble the first partition plate and the second partition plate that are vertically arranged in the middle on the base frame relative to the base plate, thereby forming a casting space and forming a mold box; then assemble several mold boxes into a mold box group.

[0010] (2) Placement of blocks: Place a ring of support frames with the same height as the base frame around the mold box, and place blocks on each of the support frames. Place each block against the corresponding side of the mold box to resist the side pressure of the mold box.

[0011] (3) Concrete pouring and vibration: Pour from the perimeter of the formwork box towards the center, and vibrate once every 30cm to 60cm. After all the pouring is completed, apply a second layer of grout to the top surface in time.

[0012] In the above steps, the specific sequence of pouring and vibration is required as follows:

[0013] (3.1) When the number of mold boxes is 1, the single pouring height is ≤600mm, and vibration is performed once every 60cm of pouring;

[0014] (3.2) When the number of formwork boxes is 2, the single pouring height is ≤300mm, and the pouring height difference between adjacent formwork boxes is ≤300mm. Vibration is performed once every 30cm to 60cm of pouring, and pouring or vibration can be carried out alternately.

[0015] (3.3) When the number of mold boxes is greater than 2 and the mold boxes form a square, the single pouring height is ≤300mm and the pouring height difference between adjacent mold boxes is ≤300mm. Vibration is performed once every 30cm of pouring. Simultaneous pouring and alternating vibration are allowed, as well as counterclockwise or clockwise rotational pouring or vibration.

[0016] (3.4) When the number of mold boxes is greater than 2 and the mold boxes form a rectangle, the single pouring height is ≤300mm and the pouring height difference between adjacent mold boxes is ≤300mm. Vibration is performed once every 30cm of pouring. Pouring or vibration can be performed simultaneously. Alternatively, starting from the short side of the rectangle formed by the mold boxes, pouring or vibration can be performed sequentially along the transverse direction in the order of arrangement.

[0017] (4) Curing: After the concrete is poured, cover it with geotextile and sprinkle water in time to keep it moist.

[0018] (5) Remove the blocks: When the concrete strength meets the requirements for demolding and handling, use a forklift to remove the blocks and support frames around the formwork box;

[0019] (6) Demolding and moving counterweights: First, remove the mold box, then move the counterweights, and then you can enter the next casting production cycle.

[0020] Preferably, in step (1) above, the base frame includes a first pad, a second pad, a third pad, a fourth pad, and a fifth pad. The first, second, third, fourth, and fifth pads are all cuboid structures made of steel or concrete, and their widths and heights are correspondingly identical.

[0021] The first pad is arranged horizontally and longitudinally, and a long strip-shaped first groove is vertically embedded in the center of its upper surface. The two ends of the first groove extend vertically to the front and rear surfaces of the first pad, respectively, and its depth is less than the height of the first pad. A long strip-shaped second groove is also vertically embedded in the front side of the upper surface of the first pad. The second groove intersects the first groove in a cross shape, and its width and depth correspond to the width and depth of the first groove, respectively. The two ends of the second groove extend vertically to the left and right sides of the first pad, respectively, and its depth is less than the height of the first pad.

[0022] The second pad is arranged horizontally and vertically, and a long strip-shaped third groove is also vertically embedded in the center of its upper surface. The width and depth of the third groove correspond to the width and depth of the first groove, respectively, and its two ends extend vertically out of the front and rear surfaces of the second pad, respectively. The depth of the groove is less than the height of the second pad.

[0023] The third pad is horizontally arranged, and a long strip-shaped fourth groove is vertically embedded in the center of its upper surface. The width and depth of the fourth groove correspond to the width and depth of the first groove, respectively, and its two ends extend vertically to the left and right sides of the third pad, respectively. The depth of the groove is less than the height of the third pad.

[0024] The fourth pad is arranged horizontally, and its length is the same as that of the third pad.

[0025] The fifth pad is arranged horizontally and longitudinally, and a long strip-shaped fifth groove is vertically embedded in the center of its upper surface. The width and depth of the fifth groove correspond to the width and depth of the first groove, respectively, and its two ends extend vertically to the front and rear surfaces of the fifth pad, respectively. Its depth is less than the height of the fifth pad. A long strip-shaped sixth groove is also vertically embedded in the center of the upper surface of the fifth pad. The sixth groove intersects the fifth groove in a cross shape, and its width and depth correspond to the width and depth of the fifth groove, respectively. The two ends of the sixth groove extend vertically to the left and right sides of the fifth pad, respectively, and its depth is less than the height of the fifth pad.

Two first partitions are respectively arranged vertically in parallel along the longitudinal direction on the left and right outer sides of the base plate, and two second partitions are respectively arranged vertically in parallel along the transverse direction on its front and rear outer sides. The height of each first partition and the second partition is the same, and their lower ends are... The components are respectively inserted into the corresponding grooves on the upper surface of the base frame, and it is necessary to ensure that the four sides of the base plate are tightly abutted against the inner side of the corresponding first partition and the inner side of the corresponding second partition. The upper ends of adjacent first partitions, adjacent second partitions, and adjacent first and second partitions are respectively connected and fixed by matching buckles to form a mold box. When assembling the mold box group, the upper ends of the first partition and the corresponding second partition of the adjacent mold box are further connected and fixed by matching buckles.

[0027] Preferably, the buckles include L-shaped buckles, straight buckles, T-shaped buckles, and cross-shaped buckles;

The two ends of the long strip-shaped slot extend vertically to the corresponding end faces of the straight buckle, and its depth is less than the height of the corresponding straight buckle. The width of the long strip-shaped slot matches the thickness of the first and second partitions, and its depth matches the depth of the L-shaped slot. Thus, the straight buckle enables a nested fixed connection between the upper ends of adjacent first partitions and between the upper ends of adjacent second partitions.

The three ends of the T-shaped slot extend vertically to the corresponding end faces of the T-shaped buckle, and its depth is less than the height of the corresponding T-shaped buckle. The width of the T-shaped slot matches the thickness of the first and second partitions, and its depth matches the depth of the L-shaped slot. Thus, the T-shaped buckle enables a nested fixed connection between the upper ends of two adjacent first partitions and the corresponding second partitions, as well as between the upper ends of two adjacent second partitions and the corresponding first partitions.

[0031] The cross-shaped buckle is horizontally positioned, and a cross-shaped groove is vertically embedded at the center of its lower surface along its trajectory. The four ends of the cross-shaped groove extend vertically to the corresponding end faces of the cross-shaped buckle, and its depth is less than the height of the corresponding cross-shaped buckle. The width of the cross-shaped groove matches the thickness of the first and second partitions, and its depth matches the depth of the L-shaped groove. Thus, the two first partitions and the upper ends of the two adjacent second partitions, which are arranged in a cross shape, are nested and fixedly connected by the cross-shaped buckle.

[0065] (2) The partitions of the template box of the present invention are connected by plug-in, and the partitions are connected by snap-fit, without any bolts or welding, which makes the construction, assembly and dismantling of the template very convenient, fast and efficient; moreover, since the partitions are made of conventional plates, there is no need for reinforcing ribs, which further reduces the processing cost and labor assembly cost of the template.

[0066] (3) The present invention blocks the side pressure of the mold box by setting blocks around the mold box, and no longer uses the traditional template support technology, which greatly improves the assembly efficiency of the template and reduces the cost of the template.

[0067] (4) By adopting a reasonable casting method, the lateral pressure between the materials inside adjacent mold boxes cancels each other out, thereby eliminating the need for support devices and reinforcing ribs between mold boxes and greatly reducing the material cost of mold boxes.

[0068] (5) As the number of counterweights that can be used to replace the blocks increases, the number of mold boxes can be increased exponentially, and even hundreds or thousands of mold boxes can be cast at the same time, thereby greatly improving the production speed.

[0093] (1) Mold box assembly: First, lay out the line and measure, assemble and place the base frame, then place the base plate 1 horizontally in the middle of the upper surface of the base frame, and then assemble the first partition plate 2 and the second partition plate 3 vertically arranged around the base plate 1 on the base frame, thereby forming a casting space 15 to form a mold box; then assemble several mold boxes into a mold box group; the number of mold boxes is assembled according to the requirements, and can be assembled into one mold box or multiple mold boxes to form a mold box group.

[0094] In the above steps, the base frame includes a first pad 4, a second pad 5, a third pad 6, a fourth pad 7, and a fifth pad 8. The first pad 4, second pad 5, third pad 6, fourth pad 7, and fifth pad 8 are all rectangular structures made of steel or concrete, and their widths and heights are identical.

[0095] like Figure 12As shown, the first pad 4 is arranged horizontally and longitudinally, and a long strip-shaped first groove 41 is vertically embedded in the center of its upper surface. The two ends of the first groove 41 extend vertically to the front and rear surfaces of the corresponding first pad 4, and its depth is less than the height of the corresponding first pad 4. A long strip-shaped second groove 42 is also vertically embedded in the front side of the upper surface of the first pad 4. The second groove 42 is arranged in a cross shape with the corresponding first groove 41, and its width and depth are consistent with the width and depth of the first groove 41, respectively. The two ends of the second groove 42 extend vertically to the left and right sides of the corresponding first pad 4, and its depth is less than the height of the corresponding first pad 4.

[0096] like Figure 13 As shown, the second pad 5 is arranged horizontally and longitudinally, and a long strip-shaped third groove 51 is also vertically embedded in the center of its upper surface. The width and depth of the third groove 51 correspond to the width and depth of the first groove 41, respectively, and its two ends extend vertically out of the front and rear surfaces of the corresponding second pad 5, and its opening depth is less than the height of the corresponding second pad 5.

[0097] like Figure 14 As shown, the third pad 6 is horizontally arranged, and a long strip-shaped fourth groove 61 is vertically embedded in the center of its upper surface. The width and depth of the fourth groove 61 correspond to the width and depth of the first groove 41, respectively, and its two ends extend vertically to the left and right sides of the corresponding third pad 6. Its opening depth is less than the height of the corresponding third pad 6.

[0098] like Figure 15 As shown, the fourth pad 7 is horizontally positioned, and its length is the same as that of the third pad 6.

[0099] like Figure 16 As shown, the fifth pad 8 is arranged horizontally and longitudinally, and a long strip-shaped fifth groove 81 is vertically embedded in the center of its upper surface. The width and depth of the fifth groove 81 correspond to the width and depth of the first groove 41, respectively, and its two ends extend vertically out of the front and rear surfaces of the corresponding fifth pad 8. Its opening depth is less than the height of the corresponding fifth pad 8. A long strip-shaped sixth groove 82 is also vertically embedded in the center of the upper surface of the fifth pad 8. The sixth groove 82 is arranged in a cross shape with the corresponding fifth groove 81, and its width and depth correspond to the width and depth of the fifth groove 81, respectively. The two ends of the sixth groove 82 extend vertically out of the left and right sides of the corresponding fifth pad 8, and its opening depth is less than the height of the corresponding fifth pad 8.

[0100] In the above steps, the base plate 1 is a rectangular steel plate or precast concrete slab, and several anchor bars are provided on its upper part; the first partition plate 2 and the second partition plate 3 can be made of steel plate, bamboo plywood, wood board, cement board, plastic board or aluminum plate, and their thicknesses are respectively matched with the width of the first groove 41. Two first partition plates 2 are respectively arranged vertically in parallel along the longitudinal direction on the left and right outer sides of the base plate 1, and two second partition plates 3 are respectively arranged vertically in parallel along the transverse direction on its front and rear outer sides. The height of each first partition plate 2 and second partition plate 3 is the same, and their lower ends are... Do not insert into the groove corresponding to the upper surface of the base frame. Ensure that the four sides of the base plate 1 are tightly abutted against the inner side of the corresponding first partition 2 and the inner side of the corresponding second partition 3. The upper ends of adjacent first partition 2, adjacent second partition 3, and adjacent first partition 2 and second partition 3 are connected and fixed by matching buckles to form a mold box. When assembling the mold box group, the upper ends of the first partition 2 and the corresponding second partition 3 of adjacent mold boxes are connected and fixed by matching buckles.

[0101] The buckle of this invention includes an L-shaped buckle 10, a straight buckle 11, a T-shaped buckle 12, and a cross-shaped buckle 13; wherein,

[0102] like Figure 17 As shown, the L-shaped buckle 10 is horizontally arranged, and an L-shaped groove is vertically embedded in the center of its lower surface along its trajectory direction. The two ends of the L-shaped groove extend vertically to the corresponding end faces of the L-shaped buckle 10, and the depth of the groove is less than the height of the L-shaped buckle 10. The width of the L-shaped groove matches the thickness of the first partition 2 and the second partition 3, thereby using the L-shaped buckle 10 to nest and fix the upper ends of the first partition 2 and the adjacent second partition 3.

[0103] like Figure 18 As shown, the straight buckle 11 is horizontally arranged, and a long strip-shaped slot is vertically embedded in the center of its lower surface along its trajectory direction. The two ends of the long strip-shaped slot extend vertically to the corresponding end faces of the straight buckle 11, and its opening depth is less than the height of the corresponding straight buckle 11. The width of the long strip-shaped slot matches the thickness of the first partition 2 and the second partition 3, and its depth is consistent with the depth of the L-shaped slot. Thus, the straight buckle 11 is used to nest and fix the upper ends of adjacent first partition 2 and adjacent second partition 3.

[0104] like Figure 19As shown, the T-shaped buckle 12 is horizontally arranged, and a T-shaped slot is vertically embedded in the center of its lower surface along its trajectory direction. The three ends of the T-shaped slot extend vertically to the corresponding end faces of the T-shaped buckle 12, and its opening depth is less than the height of the corresponding T-shaped buckle 12. The width of the T-shaped slot matches the thickness of the first partition 2 and the second partition 3, and its depth matches the depth of the L-shaped slot. Thus, the T-shaped buckle 12 can be used to nest and fix the upper ends of two adjacent first partitions 2 and the corresponding second partitions 3, as well as the upper ends of two adjacent second partitions 3 and the corresponding first partitions 2.

[0105] like Figure 20 As shown, the cross-shaped buckle 13 is horizontally arranged, and a cross-shaped groove is vertically embedded in the center of its lower surface along its trajectory direction. The four ends of the cross-shaped groove extend vertically to the corresponding end faces of the cross-shaped buckle 13, and its opening depth is less than the height of the corresponding cross-shaped buckle 13. The width of the cross-shaped groove matches the thickness of the first partition 2 and the second partition 3, and its depth matches the depth of the L-shaped groove. Thus, the upper ends of the two first partitions 2 and the two adjacent second partitions 3 arranged in a cross shape are nested and fixedly connected by the cross-shaped buckle 13.

[0106] (2) Place the stop block 14: Place a support frame with the same height as the base frame around the mold box, and place the stop block 14 on each support frame. Place each stop block 14 against the corresponding side of the mold box to resist the side pressure of the mold box.

[0107] In the above steps, each support frame can be formed by horizontally splicing several fourth pads 7 to ensure that its height is consistent with the height of the base frame; the height of each stop block 14 is lower than the height of the mold box, so that the stop block 14 can play the role of resisting the side pressure of the mold box, and its shape and weight are consistent with the size and weight of the counterweight block produced by the casting space 15. Therefore, when the number of mold boxes is ≥4, it is convenient to use the counterweight block to replace the stop block 14, reducing the production demand of the stop block 14, reducing production costs, and improving production efficiency.

[0108] In the production of single-mold boxes and double-mold boxes, the present invention can use the stop block 14 for blocking; as the production quantity of counterweights increases, the counterweights can be used to replace the stop block 14. As the number of counterweights that can be used to replace the stop block 14 increases, the number of mold boxes can increase exponentially, and even hundreds or thousands of mold boxes can be cast simultaneously. The exponential process is as follows: single mold box → double mold box → 4 mold boxes → 8 mold boxes → 24 mold boxes → 48 mold boxes... 120 mold boxes, etc., which can greatly improve the production speed.

[0109] (3) Concrete pouring and vibration: When pouring the formwork, pour from the periphery of the formwork towards the center, and vibrate once every 30cm to 60cm. After all the pouring is completed, apply a second layer of grout to the top surface in time.

[0110] (4) Curing: After the concrete is poured, cover it with geotextile and spray water in time to keep it moist.

[0111] (5) Remove block 14: When the concrete strength meets the requirements for demolding and handling, use a forklift to remove the block 14 and support frame around the mold box.

[0112] (6) Demolding and moving counterweights: First, remove the mold box, then move the counterweights, and then you can enter the next casting production cycle.

[0113] Example 1

[0116] The specific process for assembling single-module boxes in the above steps is as follows:

[0117] (1.1.1) Four first pads 4 are arranged in a rectangular horizontal longitudinal interval, and a second pad 5 is also arranged horizontally longitudinally between each two adjacent first pads 4.

And ensure that each third groove 51 is aligned with the center line of the adjacent first groove 41, thereby forming the longitudinal groove of the base frame.

Each fourth pad 7 is arranged horizontally and is staggered with each transport hole 9.

Their upper ends are nested and fixedly connected by straight buckles 11. The upper ends of each first partition 2 and the adjacent second partition 3 are nested and fixedly connected by L-shaped buckles 10, thereby forming a casting space 15 with the base plate 1 to form a single mold box. The height of the casting space 15 is lower than the height of the single mold box.

[0122] (2) Place the blocks 14: Place a ring of support frames around the mold box, and place the four blocks 14 on the corresponding support frames, and ensure that the blocks 14 are in close contact with the corresponding side of the mold box, so as to resist the side pressure of the mold box through the blocks 14.

[0123] (3) Concrete pouring and vibration: When pouring the formwork, pour from the periphery of the formwork towards the center. The height of each pour should be ≤600mm. Vibrate once every 60cm of pouring. After all the pouring is completed, the upper surface should be finished with a second layer of grout.

[0124] (4) Curing: After the concrete is poured, cover it with geotextile and spray water in time to keep it moist.

[0125] (5) Remove block 14: When the concrete strength meets the requirements for demolding and handling, use a forklift to remove the block 14 and support frame around the mold box.

[0126] (6) Demolding and transporting counterweights: First, remove the buckles on the top of the mold box, then pull out the first partition 2 and the second partition 3 around the mold box in sequence, then insert the fork of the fork into the corresponding transport hole 9, and transport the counterweight to the designated location for storage; finally, enter the next casting production cycle.

Therefore, this embodiment can realize large-scale, high-efficiency casting and production of counterweight blocks.

[0174] (1) The present invention simplifies the casting template structure through reasonable structural design, improves template assembly efficiency, reduces template processing and assembly costs, and optimizes the casting process, thereby realizing large-scale, high-efficiency and low-cost casting of gravity energy storage counterweights, meeting the requirements of mass production of counterweights for gravity energy storage projects.

[0175] (2) The partitions of the template box of the present invention are connected by plug-in, and the partitions are connected by snap-fit, without any bolts or welding, which makes the construction, assembly and dismantling of the template very convenient, fast and efficient; moreover, since the partitions are made of conventional plates, there is no need for reinforcing ribs, which further reduces the processing cost and labor assembly cost of the template.

[0176] (3) The present invention blocks the side pressure of the mold box by setting blocks 14 around the mold box, and no longer uses the traditional template support technology, which greatly improves the assembly efficiency of the template and reduces the cost of the template.

[0177] (4) By adopting a reasonable casting method, the lateral pressure between the materials inside adjacent mold boxes cancels each other out, thereby eliminating the need for support devices and reinforcing ribs between mold boxes and greatly reducing the material cost of mold boxes.

[0178] (5) As the number of counterweights that can be used to replace the stop block 14 increases, the number of mold boxes can be increased exponentially, and even hundreds or thousands of mold boxes can be cast at the same time, thereby greatly improving the production speed.

[0179] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, all modifications and improvements made by those skilled in the art to the technical solutions of the present invention should fall within the protection scope of the present invention.
