Description

Technical Field

[0001] The present invention relates to the technical field of bridge manufacturing, and more specifically to a concrete synchronous spraying and curing device for a bridge-building machine. Background Art

[0002] The synchronous concrete spray curing device of the bridge-building machine is a device used for automatic water spray curing of newly poured concrete structures during bridge construction. The main purpose of this device is to provide the necessary humidity and temperature conditions in the early stage of concrete hardening to ensure that the concrete can be properly cured and avoid cracks and other quality problems caused by too fast drying. The spray curing device is usually integrated with the bridge-building machine and starts working after the concrete pouring is completed.

[0003] In large-scale multi-span continuous beam bridge construction projects, the cantilever casting method is often used for construction. In order to ensure that the concrete in the newly poured web area is fully cured in the early stage of hardening, a concrete synchronous spray curing device integrated into the bridge-building machine (basket) will be used. The area maintained by the spray curing device mainly includes the 0# section and the standard beam section; and in order to reduce the dead weight of each beam section and improve the bending performance of the beam section, a hollow structure, that is, a hollow section structure, is provided in the middle of each newly poured standard beam section. The hollow section structure includes a bottom plate portion, a web portion and a top plate portion. It can achieve the above-mentioned weight reduction and improved bending performance goals while ensuring the structural strength and stability of the standard beam section.

[0004] Based on the above background, after the newly poured 0# section and standard beam section concrete, the outer surface and internal hollow section structure of the beam section need to be sprayed and cured to promote the cement hydration reaction of the concrete. However, the formwork of the standard beam section is gradually removed after the concrete strength meets the requirements. Before the formwork is removed, it can only be cured by spraying water on the formwork surface. The water sprayed on the formwork surface penetrates into the formwork through the holes or gaps reserved on the formwork surface under capillary action, thereby keeping the concrete surface in contact with the inner wall of the formwork in a moist state. After the formwork is removed, the outer surface and internal hollow section structure of the standard beam section can be directly sprayed.

[0005] In the prior art, for a flat formwork surface, the spraying method can be to install a fixed spray pipeline to spray water evenly from top to bottom, or to use a mobile spray equipment or manual watering to maintain humidity. However, due to the complex geometric shape of the internal corners of the hollow section structure of the beam section, the up and down movement of the spray equipment will be blocked by the limit of the bottom plate and the top plate, and the spray device cannot make the spray head reach the corner of the hollow section structure. Therefore, it is impossible to ensure that the existing spray equipment sprays the internal formwork surface of the hollow section structure evenly, and the corners of the hollow section structure need to be sprayed a second time later, resulting in uneven spraying amount at the corners and other parts and discontinuous spraying process, which prolongs the construction period and acceptance time.

[0006] The present invention provides a synchronous concrete spraying and curing device for a bridge-building machine, and aims to solve the problem that the existing synchronous concrete spraying and curing device for a bridge-building machine is inconvenient to perform uniform and continuous spraying on the corners of a hollow section structure, thereby prolonging the construction period and acceptance time.

DETAILED DESCRIPTION

[0030] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0031] Refer to the instruction manual Figures 1 to 8A concrete synchronous spraying and curing device for a bridge-building machine comprises a hanger 21 mounted on a bridge-building machine frame 2, the bridge-building machine frame 2 is slidably mounted on a concrete beam section 1, a hollow section member 3 is provided in the middle of the concrete beam section 1, a spray mechanism 4 is mounted on the hanger 21, and the spray mechanism 4 is slidably connected to the hanger 21 through a linear guide mechanism 211, the spray mechanism 4 comprises a fixed seat 41, a linear drive 2 42 is provided on one side of the fixed seat 41, and spray head assemblies 43 are installed at both ends of the linear drive 2 42; a rotary drive 1 411 is installed inside the fixed seat 41, the output end of the rotary drive 1 411 is fixedly connected to a linear drive 1 4111, the output end of the linear drive 1 4111 is connected to a connecting plate 412, and the connecting plate 412 is installed On the linear drive 2 42; the spray head assembly 43 includes a connecting seat, on which a linear drive 3 431 is installed, and a spray head 435 is installed at the output end of the linear drive 3 431; the linear drive 1 4111 drives the connecting plate 412 to move linearly along the length direction of the hollow section member 3, and the rotary drive 1 411 drives the connecting plate 412, the linear drive 2 42 and the linear drive 3 431 to rotate, so that the spray head 435 rotates along the template direction of the web portion 31, the top plate portion 32 and the bottom plate portion 33 of the hollow section member 3, and the linear drive 3 431 drives the spray head 435 to approach or move away from the web portion 31, the top plate portion 32, the corner between the web portion 31 and the top plate portion 32, the bottom plate portion 33 and the corner between the top plate portion 32 and the bottom plate portion 33 of the hollow section member 3.

[0032] It should be noted that the bridge-building machine frame 2 is an existing bridge-building machine technology, the hanger 21 is located outside one end of the hollow section member 3, the nozzle 435 is an atomizing nozzle and is connected to an external water pump through a pipeline, and the web portion 31, the top plate portion 32 and the bottom plate portion 33 are all equipped with templates with spray holes. The diameter of the spray holes allows water to penetrate but does not allow uncured concrete to pass through. When there is an extremely small gap between the template and the concrete surface, moisture can penetrate into the concrete surface through capillary action. Capillary phenomenon refers to the phenomenon that liquid rises or falls in a narrow space (such as a capillary, crack or pore) due to the action of surface tension. This natural process can help moisture be evenly distributed on the entire concrete surface in contact with the inner wall of the template.

[0033] Furthermore, the linear guide mechanism 211 includes a linear guide and a guide seat 413, and the guide seat 413 is connected to the output end of the linear guide, the linear guide is installed on the hanger 21, and the guide seat 413 is fixed on the fixed seat 41. The linear guide drives the fixed seat 41 to move up and down along the hanger 21 through the guide seat 413.

[0034] It should be noted that the linear guide mechanism 211 is a prior art and is installed on the hanger 21 .

[0035] In this embodiment, the implementation scenario is specifically as follows: the hollow section member 3 is divided into several sections in the length direction, the fixing seat 41 is installed on the hanger 21 through a linear guide rail, the connecting plate 412 is pushed to move into the hollow section member 3 to reach the first section through the linear driver 1 4111, and the corresponding two groups of spray head assemblies 43 are pushed and extended to both sides through the linear driver 2 42, so that the spray head 435 is close to or away from the template of the web portion 31, and the fixing seat 41 is driven to move from top to bottom through the linear guide rail. When it reaches the bottom of the web portion 31, the linear driver 2 42 first drives the spray head assembly 43 to retract, and drives the connecting plate 412 to rotate through the rotating driver 1 411, so that the linear driver 2 42 drives the spray head assembly 43 to move to the corner, and then drives the spray head assembly 43 to extend to the corner through the linear driver 2 42, and the connecting plate 412 continues to rotate, and the linear drive adjustment of the linear driver 3 431 makes the two groups of spray heads 435 approach the templates of the top plate portion 32 and the bottom plate portion 33 respectively. After the nozzle 435 completes one rotation, it returns to its original position, completing the synchronous spraying of the web portion 31, the top plate portion 32, the bottom plate portion 33 and the corner of the first segment, and the nozzle 435 is pushed forward to the second segment by the linear driver 1 4111, and then completes one rotation to complete the spraying of the second segment, and so on, until the spraying of all segments of the hollow section member 3 is completed, and the nozzle 435 is driven by the linear driver 3 431 to move linearly as a whole, and the nozzle 435 is controlled to move with the linear driver 3 431. The spraying distance between the templates ensures uniform spraying on the template surface and corners. The nozzle 435 is driven to rotate by the rotary driver 411, which reduces the distance required for the fixed seat 41 to move up and down, and will not be blocked by the limit of the top plate 32 and the bottom plate 33, so that the nozzle 435 can reach the corner, ensuring that the web 31, top plate 32, bottom plate 33 and corners are sprayed evenly and continuously. There is no need to spray the corners for the second time, ensuring timely completion of the project and acceptance.

[0036] Since the interior of the hollow section member 3 is narrow, the lateral wind speed inside the hollow section member 3 is high in windy weather, which affects the water spraying of the sprinkler 435 toward the template, resulting in inaccurate spraying position.

[0037] Refer to the instruction manual Figures 5 to 9 In order to solve this problem, the following technical solution is also provided: a protective cover 432 is provided on the outer periphery of the nozzle 435, the protective cover 432 is fixed to the output end of the linear driver three 431, the end of the protective cover 432 away from the linear driver three 431 is an elastic component, and the length of the protective cover 432 is greater than the length of the nozzle 435.

[0038] It should be noted that the elastic component of the protective cover 432 is a rubber material or an elastic plastic part, and the elastic protective cover 432 can abut against the corner.

[0039] In this embodiment, the implementation scenario is specifically as follows: the elastic protective cover 432 abuts against the template surface to cover the spray path of the nozzle 435, effectively avoiding the influence of the lateral wind speed inside the hollow section component 3, so that the spray position of the nozzle 435 is accurate.

[0040] When there are particles and debris on the template surface, it will affect the fit between the protective cover 432 and the template surface. When the protective cover 432 moves on the template surface, it will be rubbed by the particles and debris, which will cause excessive wear of the protective cover 432 over a long period of time.

[0041] Refer to the instruction manual Figures 7 to 9 In order to solve this problem, the following technical solution is also provided: a fan blade assembly 433 is provided between the connecting seat of the spray head assembly 43 and the protective cover 432, and the fan blade assembly 433 includes a blade seat, a blade and a driving end, the driving end is installed on the blade seat, and the blade is rotatably installed on the outer periphery of the blade seat, and the blade seat is fixedly connected to the connecting seat of the spray head assembly 43 and the protective cover 432 respectively.

[0042] It should be noted that the driving end is installed at one end or inside of the blade seat, and the driving end is connected to the blade transmission. The connection methods include but are not limited to gears, chains, etc. The fan blade assembly 433 is located on the back of the protective cover 432, which can blow off the dust on the template and play a cleaning role before the protective cover 432 abuts against the template.

[0043] Furthermore, a sleeve 434 is installed on the connection seat of the sprinkler head assembly 43 , a water pipe is provided inside the sleeve 434 , and the water pipe passes through the blade seat of the fan blade assembly 433 and is connected to the sprinkler head 435 .

[0044] It should be noted that the water pipe passes through the center of the blade seat of the fan blade assembly 433 and does not affect the transmission connection between the driving end and the blade.

[0045] Furthermore, a second rotary driver 437 is provided between the connection seat of the spray head assembly 43 and the fan blade assembly 433, and the output end of the second rotary driver 437 is connected to the blade seat of the fan blade assembly 433, and the second rotary driver 437 is used to drive the protective cover 432 and the fan blade assembly 433 to rotate and adjust the angle.

[0046] It should be noted that the second rotary driver 437 is a servo motor, which is used to drive the blade seat of the fan blade assembly 433 to rotate.

[0047] In this embodiment, the implementation scenario is specifically as follows: the fan blade assembly 433 is used to first blow air to clean the template surface to blow off debris on the template surface, and then the linear driver 431 is used to push the protective cover 432 to abut against the template surface, and the rotary driver 437 is used to drive the connecting seat of the spray head assembly 43 to rotate, so as to adjust the position of the sleeve 434, and adjust the sleeve 434 to the top, bottom or one side to avoid the sleeve 434 colliding with the template when the protective cover 432 is at the corner.

[0048] In high-temperature and windy weather, hot air circulates rapidly inside the narrow hollow section member 3. The accelerated airflow speed and higher temperature will accelerate the evaporation of moisture on the formwork surface, causing the water sprayed onto the formwork surface to dry quickly, and unable to provide sufficient humidity to support the maintenance needs of the concrete.

[0049] Refer to the instruction manual Figures 5 to 10 In order to solve this problem, the following technical solution is also provided: a support seat 5 is installed on one side of the linear drive 3 431, and a reel assembly 52 is installed on the support seat 5. The reel assembly 52 includes a roller 521, and the roller 521 is rotatably connected to the support seat 5. Two groups of rollers 521 are arranged opposite to each other, and a film roll 522 is rotatably arranged between the two groups of rollers 521. The roller 521 rolls along the template surface of the web portion 31, the top plate portion 32 and the bottom plate portion 33, and a water-locking film is laid on the template surface through the film roll 522.

[0050] It should be noted that the reel assembly 52 is located on the front end side of the fan blade assembly 433 close to the protective cover 432 to reduce the impact on the fan blade assembly 433. The film roll 522 is wound with a water-locking film, which is an existing plastic film that can fit onto a wet surface.

[0051] Furthermore, a linear driver four 436 is fixedly installed on one side of the linear driver three 431, and the support seat 5 is connected to the output end of the linear driver four 436, and the linear driver four 436 drives the support seat 5 to move closer to or away from the linear driver three 431.

[0052] It should be noted that before operation, the support seat 5 is moved closer to the linear drive three 431 to reduce the occupied space and facilitate transportation and storage. During operation, the linear drive four 436 pushes the support seat 5 away from the linear drive three 431 to reduce the impact on the fan blade assembly 433.

[0053] Furthermore, an angle adjustment assembly is provided between the support seat 5 and the reel assembly 52, and the angle adjustment assembly includes a support sleeve 51, a support fork frame 511 is provided between the support sleeve 51 and the reel assembly 52, and the support fork frame 511 is rotatably connected to the roller 521, a support block 512 is hinged at the bottom of the support fork frame 511, and the support block 512 is fixedly arranged at the top end of the support sleeve 51, a guide column 513 is slidably provided inside the support sleeve 51, and the top end of the guide column 513 is rotatably connected to the support fork frame 511, a blade 514 is installed on one side of the support block 512, and the blade 514 is located at the bottom of the film roll 522, and when the guide column 513 moves downward, the angle between the support fork frame 511 and the support block 512 becomes smaller.

[0054] It should be noted that the guide column 513 moves downward to make the roller 521 close to and always abut against the template surface for rolling, so as to reduce the contact friction between the shower head assembly 43 and the template surface.

[0055] Furthermore, a linear drive 53 is installed on the support seat 5, a slot 54 is provided inside the support seat 5, a rotating block 531 is installed at the output end of the linear drive 53, and the rotating block 531 slides up and down along the inside of the slot 54, the rotating block 531 is connected to the bottom end of the guide column 513, and the linear drive 53 drives the rotating block 531 to move up and down, so that the guide column 513 drives the support fork frame 511 to flip to one side.

[0056] It should be noted that, through the automatic operation of the linear drive 53, the position of the roller 521 can be automatically adjusted so that the roller 521 always abuts against the surface of the template to roll.

[0057] In this embodiment, the implementation scenario is specifically as follows: when the nozzle 435 sprays the second segment, the water-locking film is synchronously laid to the first segment through the reel assembly 52, and the water-locking film is laid on the template through the wet surface. When the nozzle 435 is withdrawn, the guide column 513 is driven downward by the linear drive 53 to reduce the angle between the support fork frame 511 and the support block 512, and the film roll 522 moves downward and contacts the blade 514 at the bottom, cutting off the water-locking film of the film roll 522, and then driving the guide column 513 to move upward to continue the next laying work. When laying the last segment, By rotating the second driver 437 to drive the support seat 5 to flip to the other side, the scroll assembly 52 is flipped from the rear end to the front end of the protective cover 432 to carry out the final paving work. The overall water-locking film is laid on the surface of the template after spraying. In high temperature and windy weather, the template can be locked with water, avoiding high-speed hot air flow to accelerate the evaporation of water on the template surface, prolonging the residence time of water on the template surface, promoting capillary action, and ensuring that water can evenly and effectively penetrate into the newly poured concrete in the template area, thereby providing sufficient humidity to support the maintenance needs of the concrete.

[0058] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
