Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bridge manufacturing, and more particularly, to a concrete synchronous spraying maintenance device for a bridge builder. BACKGROUND

[0002] The concrete synchronous spraying maintenance device for a bridge builder is a device for automatically spraying water to maintain the newly poured concrete structure during bridge construction. The main purpose of the device is to provide the necessary humidity and temperature conditions during the initial hardening of the concrete to ensure that the concrete can be properly solidified and avoid cracks and other quality problems caused by rapid drying. The spraying maintenance device is usually integrated with the bridge builder and starts working after the concrete pouring is completed.

[0003] In large multi-span continuous beam bridge construction projects, cantilever pouring method is often used for construction. In order to ensure that the newly poured concrete in the web area is adequately maintained during the initial hardening period, a concrete synchronous spraying maintenance device integrated into the bridge builder (hanging basket) is used. The spraying maintenance device maintains the area mainly including the 0# segment and the standard beam segment. In order to reduce the self-weight of each beam segment and improve the bending resistance of the beam segment, a hollow structure, i.e., a hollow cross-section structure, is arranged in the middle of each newly poured standard beam segment. The hollow cross-section structure includes a bottom plate part, a web part, and a top plate part, which can achieve the above-mentioned weight reduction and bending resistance improvement targets while ensuring the structural strength and stability of the standard beam segment.

[0004] Based on the above background, after the newly poured 0# segment and standard beam segment concrete, the outer surface and internal hollow cross-section structure of the beam segment need to be sprayed for maintenance to promote the cement hydration reaction of the concrete. However, the formwork of the standard beam segment is gradually removed after the concrete strength meets the requirements. Before the formwork is removed, only water can be sprayed onto the surface of the formwork, and the water sprayed onto the surface of the formwork penetrates into the formwork through the preformed holes or gaps on the surface of the formwork by capillary action, thereby keeping the surface of the concrete in contact with the inner wall of the formwork in a wet state. When the formwork is removed, the outer surface and internal hollow cross-section structure of the standard beam segment can be directly sprayed.

[0005] In the prior art, for a flat template surface, the spraying mode can select a fixed spraying pipeline to uniformly spray water from top to bottom, or use a mobile spraying device or manual watering to maintain humidity. However, due to the complex geometry of the internal corner of the hollow cross-section structure of the beam segment, the up-and-down movement of the spraying device is limited and blocked by the bottom plate and the top plate, and the spraying device cannot reach the internal corner of the hollow cross-section structure, so it is impossible to ensure that the existing spraying device uniformly sprays the template surface inside the hollow cross-section structure. Subsequent spraying at the internal corner of the hollow cross-section structure is required, which results in uneven spraying amount at the internal corner and the other parts and discontinuous spraying process, prolonging the construction period and acceptance time. SUMMARY

[0006] The present application provides a concrete synchronous spraying maintenance device for a bridge builder, which solves the problem of the existing concrete synchronous spraying maintenance device for a bridge builder, which cannot uniformly and continuously spray at the internal corner of the hollow cross-section structure, prolonging the construction period and acceptance time.

[0033] It should be noted that bridge machine frame 2 is the existing bridge machine technology, hanger 21 is located at one end outside of hollow section member 3, nozzle 435 is atomizing nozzle and is communicated with external water pump through pipeline, and template with spraying hole is installed on web portion 31, top plate portion 32 and bottom plate portion 33, and the diameter of spraying hole allows water to infiltrate but does not allow unhardened concrete to pass through, when extremely small gap exists between template and concrete surface, moisture can penetrate to concrete surface through capillary action, and capillary phenomenon refers to the phenomenon that liquid rises or falls in narrow space (such as fine tube, crack or pore) due to the action of surface tension, and the natural process can help moisture to be evenly distributed on the entire concrete surface contacted by inner wall of template.

[0035] It should be noted that linear guide mechanism 211 is prior art, and it is installed on hanger 21.

[0036] In this embodiment, the specific implementation scenario is that the hollow section member 3 is divided into several sections in the length direction, the fixed seat 41 is installed on the hanging bracket 21 through the linear guide rail, the connecting plate 412 is pushed to move to the first section inside the hollow section member 3 through the linear driver one 4111, the corresponding two groups of spray head assemblies 43 are pushed to extend to the two sides through the linear driver two 42, the spray head 435 is close to or away from the formwork of the web part 31, the fixed seat 41 is moved from top to bottom through the linear guide rail, when reaching the bottom end of the web part 31, the linear driver two 42 is first driven to retract the spray head assembly 43, the connecting plate 412 is rotated through the rotary driver one 411, the linear driver two 42 is driven to move the spray head assembly 43 to the corner, the connecting plate 412 is continuously rotated, the two groups of spray heads 435 are respectively close to the formwork of the top plate part 32 and the bottom plate part 33 for spraying through the linear driving adjustment of the linear driver three 431, the spray head 435 completes a rotation movement and returns to the original position after one rotation, the synchronous spraying of the web part 31, the top plate part 32, the bottom plate part 33 and the corner of the first section is completed, the spray head 435 is continuously pushed to the second section through the linear driver one 4111, then a rotation movement is completed, the spraying of the second section is completed, and so on, until the spraying of all sections of the hollow section member 3 is completed, the linear movement of the spray head 435 is driven by the linear driver three 431, the spraying distance between the spray head 435 and the formwork is controlled, the surface of the formwork and the corner are uniformly sprayed, the rotary movement of the spray head 435 is driven by the rotary driver one 411, the distance required for the upward and downward movement of the fixed seat 41 is reduced, the spray head 435 can reach the corner without being limited and blocked by the top plate part 32 and the bottom plate part 33, the spraying of the web part 31, the top plate part 32, the bottom plate part 33 and the corner is uniform and continuous, the corner does not need to be sprayed twice, the construction period and acceptance are ensured to be completed on time.

[0037] Due to the narrowness of the hollow section member 3, the transverse wind speed in the hollow section member 3 is fast in windy weather, which affects the water spraying of the spray head 435 to the formwork, and causes inaccurate spraying position.

[0038] Referring to the drawings in the specification Figures 5 to 9 In order to solve the problem, the following technical scheme is also provided: the outer periphery of the spray head 435 is sleeved with a protective cover 432, the protective cover 432 is fixed with 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 member, and the length of the protective cover 432 is greater than the length of the spray head 435.

[0039] It should be noted that the elastic member 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.

[0040] In the embodiment, the specific implementation scenario is that the elastic protective cover 432 abuts against the formwork surface to cover the spraying path of the spray head 435, so as to effectively avoid the influence of the internal transverse wind speed of the hollow section member 3 and ensure the accuracy of the spraying position of the spray head 435.

[0041] When the formwork surface has particle impurities, the abutment of the protective cover 432 and the formwork surface will be affected. When the protective cover 432 moves on the formwork surface, it will be rubbed by the particle impurities, which will cause excessive wear of the protective cover 432 over a long period of time.

[0042] Referring to the drawings accompanying the specification Figures 7 to 9 To solve the problem, the following technical solution is also provided: a fan blade assembly 433 is arranged between the connecting seat of the spray head assembly 43 and the protective cover 432, the fan blade assembly 433 includes a blade seat, a blade, and a driving end, the driving end is installed on the blade seat, the blade is rotatably installed on the outer periphery of the blade seat, and the blade seat is fixedly connected with the connecting seat of the spray head assembly 43 and the protective cover 432.

[0043] It should be noted that the driving end is installed on one end or inside the blade seat, the driving end is in transmission connection with the blade, and the connection mode includes but is not limited to gears, chains, etc. The fan blade assembly 433 is located at the back of the protective cover 432, which can blow off the dust on the formwork and play a cleaning role before the protective cover 432 abuts against the formwork.

[0044] Further, a sleeve 434 is installed on the connecting seat of the spray head assembly 43, the inside of the sleeve 434 is provided with a water pipe, and the water pipe penetrates through the blade seat of the fan blade assembly 433 and communicates with the spray head 435.

[0045] It should be noted that the water pipe penetrates through the center of the blade seat of the fan blade assembly 433, which does not affect the transmission connection between the driving end and the blade.

[0046] Still further, a rotary driver two 437 is arranged between the connecting seat of the spray head assembly 43 and the fan blade assembly 433, the output end of the rotary driver two 437 is connected with the blade seat of the fan blade assembly 433, and the rotary driver two 437 is used to drive the protective cover 432 and the fan blade assembly 433 to rotate and adjust the angle.

[0047] It should be noted that the rotary driver two 437 is a servo motor, which is used to drive the blade seat of the fan blade assembly 433 to rotate.

[0048] In the embodiment, the specific implementation scenario is that: the template surface is first cleaned by blowing through the fan blade assembly 433, and the sundries on the template surface are blown off, then the protective cover 432 is pushed to abut against the template surface through the linear actuator three 431, the connecting seat of the spray head assembly 43 is rotated through the rotary actuator two 437, and the position of the sleeve 434 is adjusted, so that the sleeve 434 is adjusted to the upper side, the lower side or one side, thereby avoiding the collision between the sleeve 434 and the template when the protective cover 432 is at the corner.

[0049] In the weather with high temperature and strong wind, the hot air quickly flows in the narrow hollow section member 3, and the accelerated airflow speed and the higher temperature can accelerate the evaporation of the moisture on the template surface, so that the water sprayed on the template surface quickly dries, and cannot provide sufficient humidity to support the curing needs of the concrete.

[0050] Referring to the drawings accompanying the specification Figures 5 to 10 To solve the problem, the following technical scheme is further provided: one side of the linear actuator three 431 is provided with a support seat 5, the support seat 5 is provided with a reel assembly 52, the reel assembly 52 comprises a roller 521, the roller 521 is rotatably connected with the support seat 5, two groups of rollers 521 are oppositely arranged, a film roll 522 is rotatably arranged between the two groups of rollers 521, and the roller 521 rolls along the template surface of the web plate part 31, the top plate part 32 and the bottom plate part 33, and the film roll 522 is used to lay the water-locking film on the template surface.

[0051] It should be noted that the reel assembly 52 is located at the front end side of the fan blade assembly 433 close to the protective cover 432, so as to reduce the influence on the fan blade assembly 433, the film roll 522 is wound by the water-locking film, and the water-locking film is the existing plastic film which can be attached to the wet surface.

[0052] Further, the linear actuator four 436 is fixedly installed on one side of the linear actuator three 431, the support seat 5 is connected with the output end of the linear actuator four 436, and the linear actuator four 436 drives the support seat 5 to move close to or away from the linear actuator three 431.

[0053] It should be noted that before work, the support seat 5 is close to the linear actuator three 431, so as to reduce the occupied space and facilitate transportation and storage, and when working, the support seat 5 is driven away from the linear actuator three 431 through the linear actuator four 436, so as to reduce the influence on the fan blade assembly 433.

[0054] Further, the support seat 5 is provided with an angle adjusting assembly between the support seat 5 and the reel assembly 52, the angle adjusting assembly comprises a support sleeve 51, the support sleeve 51 is provided with a support fork 511 between the support sleeve 51 and the reel assembly 52, and the support fork 511 is rotatably connected with the roller 521, the bottom of the support fork 511 is hingedly connected with a support block 512, and the support block 512 is fixedly arranged at the top end of the support sleeve 51, the inside of the support sleeve 51 is slidably provided with a guide column 513, and the top end of the guide column 513 is rotatably connected with the support fork 511, one side of the support block 512 is provided with a blade 514, and the blade 514 is located at the bottom of the film roll 522, and when the guide column 513 moves downward, the included angle between the support fork 511 and the support block 512 becomes smaller.

[0055] It should be noted that the downward movement of the guide column 513 makes the roller 521 close to and always abut against the formwork surface for rolling, which is used to reduce the contact friction between the shower head assembly 43 and the formwork surface.

[0056] Further, the support seat 5 is provided with a linear actuator five 53, the inside of the support seat 5 is provided with a slot 54, the output end of the linear actuator five 53 is provided with a rotating block 531, and the rotating block 531 slides up and down along the inside of the slot 54, the rotating block 531 is connected with the bottom end of the guide column 513, and the linear actuator five 53 drives the rotating block 531 to move up and down, so that the guide column 513 drives the support fork 511 to flip to one side.

[0057] It should be noted that through the automatic operation of the linear actuator five 53, the position of the roller 521 can be automatically adjusted, so that the roller 521 always abuts against the formwork surface for rolling.

[0058] In this embodiment, the implementation scene is specifically: when the shower head 435 sprays the second section, the water-locking film is synchronously laid on the first section through the reel assembly 52, the water-locking film is laid on the formwork through the wet surface, when the shower head 435 is withdrawn, the guide column 513 is driven downward by the linear actuator five 53, so that the included angle between the support fork 511 and the support block 512 is reduced, the film roll 522 moves downward and contacts the blade 514 at the bottom, so that the water-locking film of the film roll 522 is cut off, then the guide column 513 is driven to move upward, and the laying work is continued, in the last laying work, the support seat 5 is flipped to the other side through the rotary actuator two 437, the reel assembly 52 is flipped from the rear end to the front end of the protective cover 432, and the last laying work is carried out, the water-locking film is laid on the formwork surface after spraying, in the weather with high temperature and strong wind, the formwork plays a water-locking role, avoids that the high-speed hot air flow accelerates the evaporation of water on the formwork surface, prolongs the time for water to stay on the formwork surface, promotes capillary action, ensures that water can uniformly and effectively penetrate into the newly-poured concrete in the formwork area, so as to provide sufficient humidity to support the curing needs of the concrete.

[0059] The above embodiments only express several implementation manners of the present application, which are described in a more specific and detailed manner, but cannot be understood as a limitation on the patent scope of the present application. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application.
