Description

Technical Field

[0001] This application relates to the technical field of concrete segment production, and particularly to a rapid-curing shield segment concrete curing device. Background Art

[0002] In shield tunnel construction, shield segments are an important part of the tunnel structure, and their strength and quality are crucial for the stability and durability of the entire tunnel. To ensure that the shield segments can quickly reach the required strength, rapid-curing concrete is usually used, which can accelerate the construction progress and improve the construction efficiency at the same time.

[0003] However, problems such as cracks are likely to occur during the rapid curing of concrete segments. These problems not only affect the project progress and quality but also increase the construction cost. Therefore, during the rapid curing of concrete segments, curing treatment is also required. For example, a segment spraying curing device for building production with the publication number CN215702685U transports precast concrete segments to a perforated stainless steel load-bearing plate. The water pump pumps the water in the water storage cavity into the water storage tank and then lifts it to the spray pipe through the water pump and sprays it out through the nozzles. It can push the vehicle frame to move in the guide groove, so as to spray different positions of the precast concrete segments. The sprayed water can be filtered through the first filter screen and the second filter screen, and the dirt is washed by the water flow along the inclined first filter screen and the second filter screen to the dirt outlet for easy cleaning.

[0004] In the actual production process, to improve the site utilization rate, concrete segments are usually stored in a stacked manner from top to bottom. However, the above-mentioned prior art needs to lay the concrete segments flat on the perforated stainless steel load-bearing plate one by one, without considering the actual stacking requirements of concrete segments.

[0005] In addition to the above defects, there are still some defects in the curing of concrete segments: the above-mentioned prior art only focuses on the surface curing of a single segment and cannot effectively solve the curing requirements inside the segments in the stacked state. This technical defect leads to uneven humidity inside the stacked segments, which may affect the final strength and durability of the concrete.

[0006] Based on this, under the above statements, there is still room for improvement in the way of curing concrete segments in the prior art. Summary of the Invention

Detailed implementation manners

[0037] The following further elaborates on the present application Figures 1 to 9 in conjunction with the attached drawings.

[0038] The embodiment of the present application discloses a rapid-curing shield segment concrete curing device, which can perform covering spray curing on the concrete segments, and also reduce water loss by reducing the spacing between the concrete segments after curing.

[0039] Embodiment 1:

[0040] Refer to Figure 1 and Figure 2 A rapid-curing shield segment concrete curing device includes a storage rack 1 with a U-shaped structure and an upward opening. A distance adjustment mechanism 2 for adjusting the spacing between the concrete segments 100 is commonly installed on the vertical sections of the storage rack 1. Placement grooves for placing the concrete segments 100 are provided on the opposite surfaces of the vertical sections of the storage rack 1. Spacer blocks 3 for spacing the concrete segments 100 are arranged inside the placement grooves. A spraying mechanism 4 that penetrates into the interior of the concrete segments 100 is also installed on the side of the horizontal section of the storage rack 1. Among them, the distance adjustment mechanism 2 includes:

[0041] The distance-adjusting blocks 21 are arranged in a plurality of numbers and penetrate and slide vertically through the vertical sections of the storage racks 1 evenly. The distance-adjusting blocks 21 on the two storage racks 1 and located on the same horizontal plane correspond to each other one by one, and the distance-adjusting blocks 21 move towards the area formed between the vertical sections of the storage racks 1.

[0042] The distance-adjusting assembly 22 is installed between the vertical sections of the storage racks 1 and is used to move the distance-adjusting blocks 21.

[0043] There are two groups of spacer blocks 3 arranged symmetrically along the width direction of the vertical sections of the storage racks 1. Each group of spacer blocks 3 is arranged in a plurality of numbers evenly along the length direction of the vertical sections of the storage racks 1, and the spacer blocks 3 are slidably installed along the length direction of the vertical sections of the storage racks 1.

[0044] The concrete segment 100 is of an arc-shaped structure. During specific operation, after the concrete segment 100 is formed, the concrete segment 100 is lifted to the side of the storage rack 1 by an existing hoisting device (such as a crane, which is an existing technology and is not shown in the figure). By an existing driving force (such as manual pushing), the lowermost and vertically adjacent spacer blocks 3 are pushed apart by a certain distance. Then, the existing hoisting device is used to move the concrete segment 100 towards the part between the two vertical sections of the storage rack 1, and the concrete segment 100 is placed on the lowermost spacer blocks 3. At this time, the concrete segment 100 is in a state with the opening facing upwards. After that, the spacer blocks 3 that are closest to the concrete segment 100 and are vertically adjacent are pushed apart by a certain distance, and by repeating the above actions, the concrete segments 100 can be placed into the storage rack 1 one by one from bottom to top.

[0045] Furthermore, the spacer blocks 3 can space the concrete segments 100 placed inside the storage rack 1 by a certain distance to ensure that there is a certain space left for the distance-adjusting blocks 21 to adjust the distance of the concrete segments 100, and at the same time ensure that the subsequent concrete segments 100 can be taken out smoothly.

[0046] When the placement of the concrete segments 100 is completed, the gaps between the concrete segments 100 exactly correspond to the distance-adjusting blocks 21 one by one.

[0047] Refer to Figure 4 , in addition, a linkage rod 31 is commonly installed between the corresponding distance-adjusting block 21 and the spacer block 3, and the linkage rod 31 is slidably arranged on the corresponding distance-adjusting block 21. Furthermore, after the concrete segment 100 is placed, the position of the spacer block 3, that is, the gap between the concrete segments 100. Then, the spacer block 3 can adaptively drive the distance-adjusting block 21 to always cooperate with the gap between the concrete segments 100, ensuring that the distance-adjusting block 21 can adjust the distance of the concrete segments 100 with different thicknesses.

[0048] Guide inclined surfaces are provided on the opposite surfaces of the distance-adjusting blocks 21 that are located on the same horizontal plane and correspond to each other one by one. At this time, the bottom of the distance-adjusting block 21 is located inside the gap between the concrete segments 100.

[0049] Reference Figure 2 and Figure 3 When the concrete segments 100 need to be sprayed and cured, the distance adjusting blocks 21 on the two vertical sections of the storage rack 1 are driven to move toward each other by the distance adjusting assembly 22. During the movement of the distance adjusting blocks 21, the concrete segments 100 are driven upward by the guide slope. At this time, there is a certain distance between adjacent concrete segments 100. Specifically, the distance adjusting assembly 22 includes:

[0050] The support blocks 221 are mounted on the top of the two vertical sections of the storage rack 1 , and the two support blocks 221 are jointly mounted with a rotating rod 222 via a bearing.

[0051] There are two linkage plates 223, which correspond one to one with the two vertical sections of the storage rack 1, and are slidably arranged on the distance adjustment block 21 of the vertical section of the storage rack 1 on the corresponding side, and the two ends of the rotating rod 222 are transmission connected to the linkage plate 223 by a threaded connection.

[0052] The distance adjusting block 21 slides synchronously on the linkage plate 223 when the concrete pipe segment 100 is driven to move upward, and the screw threads on the rotating rod 222 are in opposite directions. During specific operation, the rotating rod 222 is driven to rotate by an existing drive motor (not shown in the figure). During the rotation of the rotating rod 222, the distance adjusting block 21 is driven to move toward the side of the concrete pipe segment 100 through the linkage plate 223. During the movement of the distance adjusting block 21, the concrete pipe segment 100 is driven to move upward through the guide slope, thereby driving the adjacent concrete pipe segments 100 to leave a certain distance.

[0053] Reference Figure 5 and Figure 6 , the spraying mechanism 4 includes:

[0054] The spray pipe 41 is arranged on the side of the storage rack 1, moves up and down along the length direction of the vertical section of the storage rack 1 and rotates.

[0055] The arc plate 42 cooperates with the spray pipe 41 . A moving block 43 is provided on the arc plate 42 so as to slide along its arc track, and the spray pipe 41 is rotatably installed on the moving block 43 .

[0056] A horizontal rack 44 is installed on the side of the horizontal section of the storage rack 1. An electric slider 45 is provided on the horizontal rack 44. A vertical rack 46 is installed on the electric slider 45. A sliding block 47 is installed on the vertical rack 46, and the arc plate 42 is installed on the sliding block 47.

[0057] An arc-shaped rack plate 48 is mounted on the arc-shaped plate 42 , and a gear 49 meshing with the arc-shaped rack plate 48 is mounted on the spray pipe 41 .

[0058] It should be noted that the radian of the arc-shaped plate 42 is the same as that of the concrete segment 100. If the concrete segment 100 has different radians, technicians are justified in making adaptive changes, that is, replacing the arc-shaped plate 42. Specifically, when there is a certain distance between the concrete segments 100, at this time, an external driving force (such as a cylinder, not shown in the figure) drives the sliding block 47 to move. During the movement of the sliding block 47, the arc-shaped plate 42 is driven to move synchronously. During the movement of the arc-shaped plate 42, the spray pipe 41 is driven to move a certain height in the vertical direction through the moving block 43, so that the gap between the spray pipe 41 and the two lowermost concrete segments 100 is aligned. At this time, the electric slider 45 is started again. During the movement of the electric slider 45, the spray pipe 41 is driven to be inserted into the gap between the two lowermost concrete segments 100 through the vertical frame 46.

[0059] After the spray pipe 41 is inserted into the gap between the two lowermost concrete segments 100, water is pumped into the spray pipe 41 through an external water source, and then an external driving force (such as an electric slider, not shown in the figure) drives the moving block 43 to reciprocate on the arc-shaped plate 42. During the reciprocating movement of the moving block 43, the spray pipe 41 is driven to reciprocate in the gap between the adjacent concrete segments 100. During the reciprocating movement of the spray pipe 41, the spray pipe 41 moves synchronously. Furthermore, the water flow inside the spray pipe 41 can perform curing spraying operations on the concrete segments 100.

[0060] During the movement of the spray pipe 41, the spray pipe 41 rotates synchronously through the meshing of the gear 49 and the arc-shaped rack plate 48. During the rotation of the spray pipe 41, water can be evenly sprayed onto the surface of the concrete segment 100, ensuring the uniformity of the water distribution on the surface of the concrete segment 100, and further ensuring the curing spraying effect of the concrete segment 100.

[0061] Refer to Figure 7 In order to ensure the uniform distribution effect of water on the surface of the concrete segment 100, a plurality of brush plates 411 are evenly arranged on the spray pipe 41 along its circumferential direction. Among them, hard bristles are arranged on the brush plates 411. Specifically, during the rotation of the spray pipe 41, the brush plates 411 are driven to rotate circumferentially. During the circumferential rotation of the brush plates 411, the hard bristles are driven to rotate synchronously. Furthermore, the hard bristles can evenly smear the water flow on the surface of the concrete segment 100, ensuring the uniformity of the water distribution on the surface of the concrete segment 100, so that the water can enter the inside of the concrete segment 100 to wet it, and further ensuring the curing spraying effect of the concrete segment 100.

[0062] After the curing spraying of the two lowermost concrete segments 100 is completed, the spray pipe 41 is withdrawn, and then the spray pipe 41 is moved upward by a certain distance. Repeat the above actions to make the gap between the spray pipe 41 and the remaining concrete segments 100 match, and perform curing spraying treatment on the remaining concrete segments 100.

[0063] When the spacing between the concrete segments 100 is relatively large, the sides, top, and bottom of the segments are all exposed to the air, and the total evaporation area is relatively large. In addition, when the spacing between the concrete segments 100 is relatively large, air can flow freely between the concrete segments 100, continuously carrying away the surface water vapor. Moreover, when the spacing between the concrete segments 100 is relatively large, high-humidity air is easily diffused into the surrounding environment. Therefore, in order to ensure the surface humidity of the concrete segments 100, after the spraying and curing of all the concrete segments 100 are completed, the spraying pipe 41 is withdrawn by the mutual cooperation of the electric slider 45 and the vertical frame 46. At this time, the existing drive motor is reversed to rotate the rotating rod 222. During the rotation of the rotating rod 222, the distance-adjusting block 21 is driven by the linkage plate 223 to move toward the side away from the concrete segment 100, and at this time, the concrete segment 100 is reset to the starting position.

[0064] Reducing the spacing between the concrete segments 100 can not only reduce the surface area of water evaporation and the influence of air flow on water, but also form a local high-humidity environment to ensure the surface humidity of the concrete segments 100.

[0065] Embodiment 2:

[0066] Referring to Figure 8 and Figure 9 On the basis of Embodiment 1, a support plate 11 is jointly installed at the top of the opposite surfaces of the two vertical sections of the storage rack 1, and a plurality of nozzles 12 are uniformly arranged at the bottom of the support plate 11 along its length direction.

[0067] An upward-opening U-shaped frame 13 is further installed on the sliding block 47. A plurality of groups of fixing rods 14 are uniformly arranged along the length direction of the vertical section of the U-shaped frame 13. Each group of fixing rods 14 is symmetrically arranged along the length direction of the horizontal section of the U-shaped frame 13, and the fixing rods 14 are installed on the corresponding vertical section of the U-shaped frame 13. An arc-shaped rod 15 symmetrically distributed along its length direction is jointly installed between each group of fixing rods 14, and a sponge 16 is jointly installed between the arc-shaped rods 15.

[0068] When spraying and curing the concrete segment 100 is required, after positioning and placing the concrete segment 100 on the spacer block 3, the electric slider 45 can be started without additional adjustment of the segment spacing. Through the mechanical cooperation of the vertical frame 46 and the sliding block 47, the U-shaped frame 13 is driven to translate toward the concrete segment 100. During the movement of the U-shaped frame 13, through the linkage structure of the fixing rods 14 and the arc-shaped rods 15, the sponge 16 module is driven to accurately embed into the gap between adjacent concrete segments 100. At this time, the sponge 16 completely fills the gap, and its two side edges uniformly protrude from the outer surface of the concrete segment 100 to form a covering structure.

[0069] Subsequently, connect the nozzle 12 to an external water source and perform a spraying operation on the topmost concrete segment 100. After the water soaks through the segment body, it flows downward along the surface layer by laminar flow to the lower segments. The excess water is diverted to the sponge 16 area on both sides of the segment, and the sponge 16 achieves dual functions through its water absorption characteristics:

[0070] Wastewater collection: intercept and store the excess water during the curing process to avoid water resource waste.

[0071] Continuous curing: through its own water storage capacity, slowly release water into the gaps between the segments, accelerate the water penetration efficiency, extend the moisturizing curing time, and improve the uniformity and effectiveness of the curing process.

[0072] In addition, the sponge 16 fills the gaps between the concrete segments 100, further reducing the gap distance between the concrete segments 100 and effectively moisturizing the surface of the concrete segments 100.

[0073] The implementation principle of the present invention is as follows:

[0074] (1): Lift the concrete segment 100 to the side of the storage rack 1 by an existing hoisting device, push the lowermost and vertically adjacent spacer blocks 3 apart by a certain distance through an existing driving force, then use the existing hoisting device to move the concrete segment 100 towards the part between the two vertical sections of the storage rack 1, and then place the concrete segment 100 on the lowermost spacer block 3. At this time, the concrete segment 100 is in an upward-opening state. After that, space the spacer block 3 that is closest to and vertically adjacent to the concrete segment 100 by a certain distance, and repeat the above actions to place the concrete segments 100 one by one from bottom to top inside the storage rack 1.

[0075] (2): Drive the rotating rod 222 to rotate. During the rotation of the rotating rod 222, drive the distance-adjusting block 21 to move towards the concrete segment 100 through the linkage plate 223. During the movement of the distance-adjusting block 21, drive the concrete segment 100 to move upward through the guiding inclined surface, and thus can drive the adjacent concrete segments 100 to have a certain distance.

[0076] (3): When there is a certain distance between the concrete segments 100, at this time, drive the sliding block 47 to move through an external driving force (such as a cylinder, not shown in the figure). During the movement of the sliding block 47, drive the arc-shaped plate 42 to move synchronously. During the movement of the arc-shaped plate 42, drive the spraying pipe 41 to move a certain height in the vertical direction through the moving block 43, so that the spraying pipe 41 is aligned with the gap between the lowermost two concrete segments 100. At this time, start the electric slider 45. During the movement of the electric slider 45, drive the spraying pipe 41 to insert into the gap between the lowermost two concrete segments 100 through the vertical rack 46.

[0077] (4): After the spray pipe 41 is inserted into the gap between the two lowermost concrete segments 100, water is pumped into the interior of the spray pipe 41 through an external water source, and then the moving block 43 is driven to reciprocate on the arc-shaped plate 42 by an external driving force (such as an electric slider, not shown in the figure). During the reciprocating movement of the moving block 43, the spray pipe 41 is driven to reciprocate in the gap between the adjacent concrete segments 100. During the reciprocating movement of the spray pipe 41, the spray pipe 41 moves synchronously. Thus, the water flow inside the spray pipe 41 can perform a curing spray operation on the concrete segments 100.
