Description

Technical Field

[0001] The utility model relates to the technical field of concrete curing equipment, in particular to a spray curing equipment for concrete structures. Background Technique

[0002] The curing of concrete structures is an important step to maintain the normal strength and durability of concrete after construction. If the concrete structure is not properly cured, it may cause cracks on the concrete surface, and the load-bearing capacity and durability will decrease. Therefore, in order to ensure the quality and service life of concrete structures, it is necessary to cure the newly constructed concrete. At present, spray curing equipment is mostly used to spray-cure the newly poured concrete. This kind of equipment can help maintain the humidity of the concrete surface, thereby promoting the hardening process of the concrete and helping to improve its final strength and durability.

[0003] Some curing equipment is not limited to spray curing, and can also be equipped with the laying of curing membranes and curing blankets, which can reduce labor and better cure concrete structures. However, in actual use, when laying a relatively thin curing membrane, it is easy to cause wrinkles in the curing membrane. Especially, the two ends of the laid curing membrane are prone to curl towards the middle or curl up, resulting in poor laying quality, so further optimization and improvement are still needed. For this reason, we propose a spray curing equipment for concrete structures. Summary of the Utility Model

[0004] To solve the above technical problems, the embodiment of the present application provides a spray curing equipment for concrete structures, including a frame. A moving conveyor belt is installed at the lower end of the frame. A curing membrane placement rack and a curing blanket placement rack are fixed on the upper end surface of the frame. Convex strips are integrally formed on both sides at one end of the frame, and a water supply component is arranged near the other end of the upper end surface of the frame. The equipment further includes:

[0005] A flattening component, which is hingedly arranged at one end of the frame away from the water supply component, and is used to flatten the laid curing membrane;

[0006] An anti-curling component, which is hinged to the flattening component, and is arranged on both sides of the flattening component to prevent the two sides of the laid curing membrane from curling towards the middle or curling up, and the angle between the anti-curling component and the flattening component can vary from 10° to 60°.

[0007] In some embodiments, the flattening component includes a first connecting strip and a flat pressing roller. There are two first connecting strips. The first ends of the two first connecting strips are symmetrically hinged to the two convex strips. The flat pressing roller is rotatably installed between the second ends of the two first connecting strips. A second connecting block is also hinged on the first connecting strip, and a first connecting block is also hinged on the convex strip. A spring is connected between the first connecting block and the second connecting block on the same side.

The end of the inclined pressure roller is connected to a second connecting rod, and the other end of the second connecting rod is arranged inside the mounting frame.

[0009] In some embodiments, the anti-curling component further includes a servo motor. The servo motor is mounted on the top end of the mounting frame, and the bottom end of the servo motor is connected to a first connecting rod extending into the mounting frame. A mounting seat is fixed to the lower end of the outer wall of the first connecting rod, and the other end of the second connecting rod is connected to the mounting seat.

[0010] In some embodiments, an opening for accommodating the second connecting rod is formed on one side of the mounting frame facing the flat pressure roller.

[0011] In some embodiments, the water supply component includes a water tank arranged on the machine frame and a water pump mounted inside the water tank. The water outlet end of the water pump is connected to a first water supply pipe extending outside the water tank.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Embodiment 1

[0033] Please refer to Figures 1-4 , the present utility model provides a technical solution: a spray curing device for concrete structures, including a frame 1. A moving conveyor belt 2 is installed at the lower end of the frame 1. The moving conveyor belt 2 includes a conveyor belt body, a motor, a drive shaft, and a transmission gear member, etc. The conveyor belt body is installed outside the drive shaft. The motor drives the transmission gear member to rotate, which can cooperate to drive the drive shaft and the conveyor belt body to rotate, so as to achieve movement. Specifically, reference can be made to the moving conveyor belt disclosed in the patent publication number CN116653103A, a concrete structure curing process and its spray curing device. A curing film placement rack 4 and a curing blanket placement rack 5 are fixed on the upper end surface of the frame 1. The curing film placement rack 4 is used to install the rolled-up curing film, and the curing blanket placement rack 5 is used to install the rolled-up curing blanket. Convex strips 9 are integrally formed on both sides at one end of the frame 1, and a water supply assembly 3 is provided near the other end of the upper end surface of the frame 1. Among them, the water supply assembly 3 includes a water tank 301 provided on the frame 1 and a water pump 309 installed in the water tank 301. The water outlet end of the water pump 309 is connected to a first water delivery pipe 302 extending outside the water tank 301. A spray pipe 304 is installed at the end of the first water delivery pipe 302. A plurality of atomizing nozzles 306 are installed on the lower end surface of the spray pipe 304.

[0034] When curing a concrete structure, as the device moves, the water pump 309 can be used to pump the water in the water tank 301. The water is sent to the spray pipe 304 through the first water delivery pipe 302, and then sprayed onto the upper end surface of the concrete structure through a plurality of atomizing nozzles 306, which can ensure the humidity and temperature required for the solidification of the concrete during the initial curing process.

[0035] In addition, a first guiding member 6 and a second guiding member 10 are provided at one end of the frame 1 away from the water supply assembly 3. The first guiding member 6 is used to guide the laid curing film, and the second guiding member 10 is used to guide the laid curing blanket. The position of the second guiding member 10 is higher than that of the first guiding member 6. Both the first guiding member 6 and the second guiding member 10 include a support frame and a guiding roller. The guiding roller is rotatably installed on the support frame, which can realize the orderly guiding of the curing film on the curing film placement rack 4 and the curing blanket on the curing blanket placement rack 5 to the upper end surface of the concrete structure for laying.

[0036] Refer to Figure 1 and Figure 4 As shown, the spray curing device for concrete structures further includes a guiding and flattening component 7 and an anti-curling edge component 8. The guiding and flattening component 7 is hingedly arranged at one end of the frame 1 away from the water supply component 3, and the guiding and flattening component 7 is used to flatten the laid curing film. The anti-curling edge component 8 is hinged to the guiding and flattening component 7, and the anti-curling edge component 8 is arranged on both sides of the guiding and flattening component 7 to prevent the two sides of the laid curing film from curling or rolling inwards towards the middle. Moreover, the angle between the anti-curling edge component 8 and the guiding and flattening component 7 is arranged at no more than 60°.

[0037] In a specific embodiment of the present invention, refer to Figure 5 As shown, the guiding and flattening component 7 includes a first connecting bar 71 and a flattening roller 72. There are two first connecting bars 71. The first ends of the two first connecting bars 71 are symmetrically hinged to two convex strips 9. The flattening roller 72 is rotatably installed between the second ends of the two first connecting bars 71. A second connecting block 75 is also hinged on the first connecting bar 71, and a first connecting block 74 is also hinged on the convex strip 9. A spring 73 is connected between the first connecting block 74 and the second connecting block 75 on the same side.

[0038] In a specific embodiment of the present invention, refer to Figure 5 and Figure 6 As shown, the anti-curling edge component 8 includes a mounting frame 81, an inclined pressing roller 83, and a second connecting bar 87. One end of the second connecting bar 87 is hinged to the outer wall of the frame 1, and the mounting frame 81 is installed on the other end of the outer wall of the second connecting bar 87 through a mounting plate. Moreover, the second connecting bar 87 is hinged to the first connecting bar 71. The end of the inclined pressing roller 83 is connected to a second connecting rod 85, and the other end of the second connecting rod 85 is arranged inside the mounting frame 81.

[0039] Through the above, when the curing film is exported for laying, the rotatable flattening roller 72 is located on the upper surface of the curing film, which can play a role of rolling and pressing during the forward laying process of the device, improving the flatness of the laid curing film.

[0040] Secondly, the inclined pressing rollers 83 located on both sides and arranged at an acute angle with the flattening roller 72 can focus on rolling and pressing the edges of the curing film, making it difficult for the two ends of the curing film to curl towards the middle during the laying process, and the curing film is not easy to curl. It can overall improve the quality of the laid curing film.

[0041] In addition, by using the hinge settings of the first connecting bar 71, the second connecting bar 87, the first connecting block 74, and the second connecting block 75, and the setting of the spring 73, during the laying process, for the uneven and protruding concrete structure, the flattening roller 72 and the inclined pressing roller 83 have a certain upward movement limit, avoiding damaging the curing film due to the flattening roller 72 and the inclined pressing roller 83 pressing the curing film too tightly.

[0042] Embodiment 2

[0043] The difference between this embodiment and Embodiment 1 is that, referring to Figure 5 and Figure 6 as shown, an angle change of 10-60° can be formed between the anti-curling component 8 and the flattening component 7. The anti-curling component 8 further includes a servo motor 82. The servo motor 82 is a forward and reverse motor. The servo motor 82 is installed at the top end of the installation frame 81. And the bottom end of the servo motor 82 is connected with a first connecting rod 84 extending into the installation frame 81. A mounting seat 86 is fixed at the lower end of the outer wall of the first connecting rod 84. The other end of the second connecting rod 85 is connected to the mounting seat 86. And an opening 811 for accommodating the second connecting rod 85 is formed on one side of the installation frame 81 facing the flattening roller 72.

[0044] As described above, when the servo motor 82 is started, the output end of the servo motor 82 can drive the first connecting rod 84 to rotate, and then can drive the diagonal pressing roller 83 installed on the mounting seat 86 through the second connecting rod 85 to rotate a certain angle, so as to change the angle between the diagonal pressing roller 83 and the flattening roller 72.

[0045] Specifically, it can be explained as follows: when the width of the laid curing film becomes smaller, at this time, the diagonal pressing roller 83 can be inclined towards the flattening roller 72 to reduce the angle between the diagonal pressing roller 83 and the flattening roller 72, so as to ensure that more areas of the diagonal pressing roller 83 can contact the edge of the curing film.

[0046] Among them, the angle between the diagonal pressing roller 83 and the flattening roller 72 is preferably 10-60°. If the angle is too small, it is easy to block the flattening roller 72; if the angle is too large, it will affect the treatment effect of the edge of the curing film.

[0047] Embodiment 3

[0048] The difference between this embodiment and Embodiment 1 is that, referring to Figure 1 and Figure 2 as shown, the water supply component 3 further includes a second water delivery pipe 303. One end of the second water delivery pipe 303 is connected to the first water delivery pipe 302. The other end of the second water delivery pipe 303 is installed with a water outlet pipe 305. A plurality of water outlet holes 308 are formed on the lower end surface of the water outlet pipe 305. And an external water replenishing pipe 307 is also connected to the first water delivery pipe 302. Valves are installed on the first water delivery pipe 302, the second water delivery pipe 303 and the external water replenishing pipe 307.

[0049] As described above, when a large amount of clear water needs to be sprayed in the middle stage, the valve on the first water delivery pipe 302 can be closed, the valve on the second water delivery pipe 303 can be opened, and the clear water is pumped to the second water delivery pipe 303, and then flows down through the water outlet pipe 305 provided with a plurality of water outlet holes 308, which can ensure a large amount of water supply.

[0050] Among them, an external water supply pipe can be connected to the external water delivery pipe 307, which is convenient for quickly replenishing water during a large amount of spraying, without first adding water to the water tank 301, which is relatively convenient and practical.

[0051] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0052] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
