Description

Technical Field

[0001] The utility model relates to the technical field of concrete curing, in particular to a flexibly adjustable steam curing device for concrete components. Background Art

[0002] Concrete components, such as beams, slabs, columns, and foundations, are made of reinforced concrete and are categorized as precast or cast-in-place. Factory-produced precast concrete components are energy-efficient and environmentally friendly. Concrete components are prefabricated in molds. To ensure that the finished concrete components achieve demolding strength quickly, thereby accelerating formwork turnover, improving labor productivity, and increasing production, curing measures that accelerate concrete hardening are necessary. Concrete curing methods include steam curing, hot mold curing, and solar curing.

[0003] Before working, the existing steam curing device for concrete components cannot quickly place the concrete into the steam curing box connected to the steam generating device. Workers are required to manually carry the concrete components into the curing box. Due to their large size and gravity, some components are very difficult to carry, and their use is very limited, which affects the processing efficiency. Secondly, during curing, most of the concrete components in some existing curing devices are fixed and cannot be rotated. For example, a steam curing device for recycled concrete prefabricated components with application number 202020221881.0 is provided with an air intake hood on the upper and left sides of the device, but the front and back of the concrete components cannot be steam-cured, which leads to uneven curing of the prefabricated components, thereby affecting the qualification rate and service life of the prefabricated components. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a flexibly adjustable steam curing device for concrete components to solve the technical problems in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flexibly adjustable steam curing device for concrete components, comprising a base, a curing box, a steam generator and a fixing plate are respectively provided on the top of the base, a piston box and a fixing frame are respectively provided on one side of the curing box, an exhaust pipe and an air supply pipe are respectively provided on the top of the piston box, and one end of the air supply pipe extends to the interior of the curing box and is connected to the head air distribution pipe, one end of the exhaust pipe is connected to the steam generator, a mounting frame is installed inside the curing box, a rotating shaft is installed on the mounting frame, and the top and bottom ends of the rotating shaft are respectively connected to a turntable and a driven bevel gear, a driving motor is installed on the other side of the curing box, and the output end of the driving motor is connected to A driving shaft, an active bevel gear is installed on the outer surface of the driving shaft, and one end of the driving shaft is connected to a turntable, a shift rod is fixed to one side of the turntable, a slide is provided on the inner side of the fixed frame, a piston rod extending to the inside of the piston box is fixed on the top of the slide, and a piston plate is fixed on the top of the piston rod, a hydraulic rod is installed on the back of the fixed plate, and a sealing plate is fixed on the output end of the hydraulic rod, and a connecting frame is fixed on the back of the sealing plate, a high-temperature resistant motor is provided on the top of the connecting frame, the output end of the high-temperature resistant motor is connected to a screw rod, a threaded block is sleeved on the outer surface of the screw rod, and a clamping frame is provided on the back of the threaded block, high-temperature resistant cylinders are installed on both sides of the clamping frame, and the output end of the high-temperature resistant cylinder is connected to the clamping plate

[0006] Furthermore, an automatic pressure relief valve is installed on one side of the top of the curing box.

[0007] By adopting the above technical solution, when the steam pressure in the curing box reaches a threshold, the automatic pressure relief valve can automatically relieve the pressure in the curing box, avoiding excessive pressure that may cause slight deformation of the concrete components and avoid safety accidents.

[0008] Furthermore, the top of the turntable is provided with a plurality of groups of protrusions.

[0009] By adopting the above technical solution, under the action of the protrusion, a gap is created between the bottom of the concrete component and the turntable, thereby facilitating the contact between the steam and the bottom of the concrete component.

[0010] Furthermore, the air distribution pipe is in an inverted "U" shape, and a plurality of groups of nozzles are provided on the inner side of the air distribution pipe.

[0011] By adopting the above technical solution and arranging the gas distribution pipes and a plurality of groups of nozzles, the steam can be brought into uniform contact with the concrete component.

[0012] Furthermore, one end of the shift rod extends to the inner side of the slide and is slidably engaged with the slide.

[0013] By adopting the above technical solution, when the turntable rotates, the shifting rod can shift the slide to move up and down.

[0014] Furthermore, the outer surfaces of the air extraction pipe and the air delivery pipe are both provided with one-way valves.

[0015] By adopting the above technical solution, the flow direction of steam in the exhaust pipe and the gas transmission pipe can be controlled under the action of the one-way valve.

[0016] Furthermore, the outer surfaces of the clamping plate and the clamping frame are penetrated by a plurality of groups of through holes.

[0017] By adopting the above technical solution, under the action of the through holes, the steam is not blocked by the clamping plate and the clamping frame, so that the contact between the concrete component and the steam is more uniform.

[0018] Furthermore, a control panel is installed on the outer surface of the fixing plate, and the steam generator, the driving motor, the high temperature resistant motor and the high temperature resistant cylinder are all electrically connected to the control panel.

[0019] By adopting the above technical solution, the staff can control the steam generator, drive motor, high temperature resistant motor and high temperature resistant cylinder through the control panel.

[0020] Furthermore, the driving bevel gear is meshed with the driven bevel gear, and the diameter of the driven bevel gear is larger than the diameter of the driving bevel gear.

[0021] By adopting the above technical solution, since the diameter of the driven bevel gear is larger than that of the driving bevel gear, when the driving bevel gear rotates, the driven bevel gear will rotate slowly, thereby causing the concrete component to rotate slowly.

[0022] In summary, the present invention has the following beneficial effects:

[0023] 1. The utility model is equipped with a hydraulic rod, a sealing door, a connecting frame, a high-temperature resistant cylinder, a high-temperature resistant motor, a screw rod, a threaded block, a clamping frame and a clamping plate. When placing a concrete component, the worker places the concrete component on the base, and the high-temperature resistant cylinder pushes the clamping plate to clamp and fix the concrete component. The high-temperature resistant motor drives the screw rod to rotate, so that the threaded block drives the clamping frame to move upward, and then the concrete component moves upward. The hydraulic rod pushes the sealing plate toward the curing box and seals it. Then the worker controls the high-temperature resistant cylinder to contract, so that the concrete component is prevented from being on the turntable. In this way, there is no need for the worker to manually lift the concrete component into the curing box, making it more convenient to take out and put in, greatly reducing manpower input and improving production and processing efficiency.

[0024] When the piston plate moves upward, the steam in the steam generator is sucked into the steam pipe by the exhaust pipe, and when the piston plate moves upward, the steam is sent into the curing box by the air supply pipe and the air distribution pipe, and the steam is sprayed onto the outer surface of the concrete component through the nozzle. At the same time, the rotation of the driving shaft will cause the active bevel gear to rotate, and the active bevel gear will cause the driven bevel gear to rotate slowly, thereby causing the rotating shaft and the turntable to drive the concrete component to rotate slowly. By causing the concrete component to rotate slowly, the purpose of flexibly adjusting the angle of the concrete component is achieved, and the steam can be evenly sprayed onto the outer surface of the concrete component, thereby improving the curing effect of the concrete component.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] The following describes an embodiment of the present invention based on its overall structure.

[0033] Example 1: A flexible steam curing device for concrete components, such as Figure 1-Figure 5As shown, it includes a base 1, and a curing box 2, a steam generator 3 and a fixing plate 4 are respectively provided on the top of the base 1. An automatic pressure relief valve 8 is installed on one side of the top of the curing box 2. When the steam pressure in the curing box 2 reaches a threshold, the automatic pressure relief valve 8 can automatically relieve the pressure in the curing box 2 to avoid excessive pressure causing slight deformation of the concrete component and safety accidents. A piston box 9 and a fixing frame 12 are respectively provided on one side of the curing box 2. An exhaust pipe 10 and an air supply pipe 11 are respectively provided on the top of the piston box 9, and one end of the air supply pipe 11 extends to the interior of the curing box 2 and is connected to the head gas distribution pipe 23. The exhaust pipe One end of 10 is connected to the steam generator 3, and a mounting frame 13 is installed inside the curing box 2. A rotating shaft 14 is installed on the mounting frame 13, and the top and bottom ends of the rotating shaft 14 are respectively connected to a turntable 15 and a driven bevel gear 16. A driving motor 17 is installed on the other side of the curing box 2, and the output end of the driving motor 17 is connected to a driving shaft 18. The outer surface of the driving shaft 18 is installed with a driving bevel gear 19, and the driving bevel gear 19 is meshed with the driven bevel gear 16, and the diameter of the driven bevel gear 16 is larger than the diameter of the driving bevel gear 19. Since the diameter of the driven bevel gear 16 is larger than the diameter of the driving bevel gear 19, when the driving bevel gear 19 is engaged with the driven bevel gear 16, the driving bevel gear 19 is engaged with the driven bevel gear 16. When the bevel gear 19 rotates, the driven bevel gear 16 will rotate slowly, so that the concrete component can rotate slowly, and one end of the drive shaft 18 is connected to a turntable 25, and a lever 26 is fixed to one side of the turntable 25. A slide 20 is provided on the inner side of the fixed frame 12, and a piston rod 21 extending to the inside of the piston box 9 is fixed on the top of the slide 20, and a piston plate 22 is fixed on the top of the piston rod 21. A hydraulic rod 6 is installed on the back of the fixed plate 4, and a sealing plate 7 is fixed to the output end of the hydraulic rod 6, and a connecting frame 28 is fixed to the back of the sealing plate 7. A high-temperature resistant motor 29 is provided on the top of the connecting frame 28. The output end of the high-temperature resistant motor 29 is connected to a screw rod 30, the outer surface of the screw rod 30 is sleeved with a threaded block 31, and the back of the threaded block 31 is provided with a clamping frame 32, high-temperature resistant cylinders 33 are installed on both sides of the clamping frame 32, and the output end of the high-temperature resistant cylinder 33 is connected to a clamping plate 34, the outer surface of the fixed plate 4 is installed with a control panel 5, and the steam generator 3, the drive motor 17, the high-temperature resistant motor 29 and the high-temperature resistant cylinder 33 are all electrically connected to the control panel 5. The staff can control the steam generator 3, the drive motor 17, the high-temperature resistant motor 29 and the high-temperature resistant cylinder 33 through the control panel 5.

[0034] See Figure 2-Figure 4 In the above embodiment, a plurality of groups of protrusions 27 are provided on the top of the turntable 15. Under the action of the protrusions 27, a gap is created between the bottom of the concrete component and the turntable 15, thereby facilitating contact between the steam and the bottom of the concrete component.

[0035] See Figure 2-Figure 4In the above embodiment, the air distribution pipe 23 is in an inverted "U" shape, and a plurality of groups of nozzles 24 are provided on the inner side of the air distribution pipe 23. Through the arrangement of the air distribution pipe 23 and the plurality of groups of nozzles 24, the steam can be in uniform contact with the concrete component.

[0036] See Figure 1-Figure 4 In the above embodiment, one end of the lever 26 extends to the inner side of the slide 20 and slides with the slide 20. When the turntable 25 rotates, the lever 26 can move the slide 20 up and down.

[0037] See Figure 2-Figure 4 Under the action of the one-way valve, the flow direction of steam in the exhaust pipe 10 and the gas delivery pipe 11 can be controlled.

[0038] Example 2: In order to prevent the clamping plate and the clamping frame from affecting the contact effect between the steam and the concrete component, Example 2 is improved on the basis of Example 1. Figure 4 and Figure 5 The outer surfaces of the clamping plate 34 and the clamping frame 32 are penetrated by several groups of through holes. Under the action of the through holes, the steam is not blocked by the clamping plate 34 and the clamping frame 32, so that the contact between the concrete component and the steam is more uniform.

[0039] The implementation principle of the present invention is as follows: when placing a concrete component, the worker places the concrete component on the base 1, the high-temperature resistant cylinder 33 pushes the clamping plate 34 to clamp and fix the concrete component, the high-temperature resistant motor 29 drives the screw rod 30 to rotate, so that the threaded block 31 drives the clamping frame 32 to move upward, and then the concrete component moves upward, the hydraulic rod 6 pushes the sealing plate 7 to move closer to the curing box 2 and seal it, and then the worker controls the high-temperature resistant cylinder 33 to contract, so that the concrete component is prevented from being on the turntable 15, the drive motor 17 drives the drive shaft 18 to rotate, the drive shaft 18 drives the turntable 25 to rotate, and the turntable 25 drives the lever 26 to drive the slide 20 to move up and down in the fixed frame 12, and then The piston rod 21 drives the piston plate 22 to perform an up and down piston movement in the piston box 9. When the piston plate 22 moves downward, the internal steam of the steam generator 3 is sucked into the steam pipe by the exhaust pipe 10. When the piston plate 22 moves upward, the steam is sent into the curing box 2 by the gas pipe 11 and the gas distribution pipe 23. The steam is sprayed onto the outer surface of the concrete component through the nozzle 24. At the same time, the rotation of the drive shaft 18 will cause the active bevel gear 19 to rotate, and the active bevel gear 19 will cause the driven bevel gear 16 to rotate slowly, thereby causing the rotating shaft 14 and the turntable 15 to drive the concrete component to rotate slowly. By causing the concrete component to rotate slowly, the steam can be evenly sprayed onto the outer surface of the concrete component, thereby achieving the purpose of steam curing.

The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
