[0001] This invention relates to the field of curing device technology, specifically to a rapid electrothermal curing device for concrete and its curing method. Background Technology

[0002] With the continuous improvement of construction engineering quality control standards, the strength testing of laboratory concrete test blocks is a core link in engineering quality verification. Its testing efficiency and the accuracy of the results directly affect the construction progress and quality assessment.

It provides efficient support for mix proportion optimization and batch quality control, and is indispensable in construction engineering laboratories.

[0003] However, existing concrete curing devices are not convenient for buffering the fixing force when fixing concrete components. This rigid fixing force can damage the surface of the component, causing cracks and affecting the experimental results. Summary of the Invention

[0004] The purpose of this invention is to provide a rapid electrothermal curing device for concrete and its curing method. By setting a buffer section, the invention solves the problem that existing concrete curing devices are not convenient for buffering the fixing force when fixing concrete components. This rigid fixing force can damage the surface of the component, resulting in cracks in the component and affecting the experimental results.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a rapid electrothermal curing concrete device and method, comprising a housing, and further comprising: a curing section disposed on the housing; a buffer section comprising a plurality of buffer sections arranged in an array within the housing; two clamping and positioning sections disposed in a linear array within the housing; two rotating sections disposed in a linear array within the housing; the buffer section comprising a buffer assembly disposed on the housing; and a sliding assembly comprising a sliding... The component is installed inside the chassis; the buffer component includes a rectangular plate disposed inside the chassis, a fixing block is fixedly connected to the left side of the rectangular plate, a rectangular box is slidably connected to the outer wall of the fixing block, a sliding sealing plate is fixedly connected to the left side of the fixing block, the outer wall of the sliding sealing plate is slidably connected to the inner wall of the rectangular box, a clamping plate is fixedly connected to the left side of the rectangular box, and a damping element is disposed between the rectangular plate and the clamping plate; the rectangular box contains a compressed inert gas, and the damping element includes two dampers fixedly connected between the clamping plate and the clamping plate; the two dampers are arranged in a mirror image on both sides of the rectangular box.

[0007] Furthermore, the sliding assembly includes a groove on the disc, a slider is slidably connected to the inner wall of the groove, the top of the slider is fixedly connected to a rectangular plate, and two telescopic protective covers are fixedly connected to the outer wall of the slider; the side of the two telescopic protective covers away from the slider is fixedly connected to the inner wall of the groove.

[0008] Furthermore, the maintenance unit includes two partition doors hinged to the front of the chassis, several infrared lights are installed on the inner wall of the chassis, two brackets are fixedly connected to the inner wall of the chassis, and a disc is rotatably connected to the inner wall of each of the two brackets; one disc is provided with two buffer parts, one clamping and positioning part and one rotating part.

[0009] Furthermore, the clamping and positioning part includes a driving assembly disposed on a disc; and a transmission assembly mounted on the disc. The driving assembly includes a second slide groove formed on the corresponding disc, an electric telescopic rod fixedly connected to the inner front wall of the second slide groove, and a rectangular slider fixedly connected to the output shaft of the electric telescopic rod. The outer wall of the rectangular slider is slidably connected to the second slide groove, and the first slide groove is connected to the second slide groove.

[0010] Furthermore, the transmission assembly includes two inclined grooves formed on a rectangular slider. The inner walls of the two inclined grooves are provided with cylindrical sliders, and the outer walls of the two cylindrical sliders are fixedly connected with sliding rods. The outer walls of the corresponding sliding rods are slidably connected to the inner walls of the first inclined groove, and the tops of the corresponding sliding rods are fixedly connected to the sliders. The inner walls of the two inclined grooves are in slidable contact with the outer walls of the two cylindrical sliders, respectively.

[0011] Furthermore, the rotating part includes a protective shell fixedly connected to the bottom of the corresponding bracket, and a motor fixedly connected to the top of the corresponding protective shell. The output shaft of the motor is fixedly connected to a rotating shaft through a coupling. The rotating shaft extends into the corresponding disc and is fixedly connected thereto.

[0012] The present invention has the following beneficial effects:

[0013] (1) The present invention sets up a buffer part, and the rectangular plate is moved by the slider to realize the positioning of the clamping plate. Then, the fixed block pushes the sliding sealing plate to squeeze the compressed inert gas in the rectangular box. The expansion and contraction of the damper forms a flexible buffer force, which can ensure that the clamping plate is tightly attached to the concrete component to complete the fixation. The buffering characteristics of the compressed inert gas and the expansion and contraction damping force of the damper form a flexible support when the clamping plate clamps the concrete component. This can avoid damage to the surface of the component caused by rigid clamping, and can also achieve stable positioning by tightly attaching to the component, preventing the component from shifting during curing and rotation. At the same time, the telescopic protective cover can protect the slide groove to prevent debris from entering during curing and affecting the operational stability of the sliding component, thus providing a guarantee for the safe clamping of the component and the long-term reliable operation of the device.

[0014] (2) By setting up a clamping and positioning part, the electric telescopic rod of the drive component pushes the rectangular slider to slide. By utilizing the sliding cooperation between the inclined groove of the transmission component and the cylindrical slider, the linear motion of the rectangular slider is converted into the opposite movement of the two sliders, thereby synchronously driving the sliders of the two buffer parts to move, realizing the centered clamping of concrete components of various sizes, ensuring that the components maintain a stable central position during the curing process, and providing the prerequisite for the rotating part to drive the components to be heated evenly.

[0015] (3) By setting up a rotating part, the motor drives the rotating shaft to rotate, which drives the disc to rotate slowly on the support, so that the concrete components placed on the disc rotate synchronously. Combined with the infrared lamp of the curing part, it achieves more uniform heating, avoids quality problems such as cracks caused by uneven heating of the components, improves the efficiency and quality of electrothermal curing, and ensures that the strength and performance of the concrete components after curing meet the standards.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-8As shown, the present invention is a rapid electrothermal curing concrete device and its curing method, including a housing 111, and further including: a curing section 1, which is disposed on the housing 111; a buffer section 2, of which several buffer sections 2 are arranged in an array inside the housing 111; two clamping and positioning sections 3, of which two clamping and positioning sections 3 are arranged in a linear array inside the housing 111; and two rotating sections 4, of which two rotating sections 4 are arranged in a linear array inside the housing 111. The curing section 1 includes two partition doors 112 hinged to the front side of the housing 111. A plurality of infrared lamps 113 are installed on the inner wall of the housing 111. Two supports 114 are fixedly connected to the inner wall of the housing 111. A disc 115 is rotatably connected to the inner wall of each of the two supports 114. Two buffer sections 2, one clamping and positioning section 3, and one rotating section 4 are disposed on one disc 115.

[0030] The buffer section 2 includes a buffer assembly 21, which is mounted on the chassis 111; and a sliding assembly 22, which is installed inside the chassis 111. The buffer assembly 21 includes a rectangular plate 211 disposed inside the chassis 111. A fixing block 212 is fixedly connected to the left side of the rectangular plate 211. A rectangular box 213 is slidably connected to the outer wall of the fixing block 212. A sliding sealing plate 214 is fixedly connected to the left side of the fixing block 212. The outer wall of the sliding sealing plate 214 is slidably connected to the inner wall of the rectangular box 213. A clamping plate 215 is fixedly connected to the left side of the rectangular box 213. A damping element is disposed between the rectangular plate 211 and the clamping plate 215. The rectangular box 213 contains a compressed inert gas. The damping element includes a component fixedly connected between the clamping plates 215. Two dampers 216 are mirror images of each other on both sides of the rectangular box 213. The sliding assembly 22 includes a groove 221 on the disc 115. A slider 222 is slidably connected to the inner wall of the groove 221. The top of the slider 222 is fixedly connected to the rectangular plate 211. Two telescopic protective covers 223 are fixedly connected to the outer wall of the slider 222. The side of the two telescopic protective covers 223 away from the slider 222 is fixedly connected to the inner wall of the groove 221. By setting the buffer part 2, a flexible support is formed when the clamping plate 215 clamps the concrete component. This can avoid damage to the surface of the component caused by rigid clamping, avoid cracks in the component that affect the experimental results, and also fit the component to achieve stable positioning, preventing the component from shifting during curing and rotation.

[0031] The clamping and positioning part 3 includes a drive assembly 31, which is mounted on the disk 115; and a transmission assembly 32, which is also mounted on the disk 115. The drive assembly 31 includes a second slide groove 311 formed on the corresponding disk 115. An electric telescopic rod 312 is fixedly connected to the inner front wall of the second slide groove 311, and a rectangular slider 313 is fixedly connected to the output shaft of the electric telescopic rod 312. The outer wall of the rectangular slider 313 is slidably connected to the second slide groove 311. A first slide groove 221 communicates with the second slide groove 311. The transmission assembly 32 includes two inclined grooves 313 formed on the rectangular slider 313. 21. The inner walls of the two inclined grooves 321 are each provided with a cylindrical slider 322. The outer walls of the two cylindrical sliders 322 are each fixedly connected with a sliding rod 323. The outer walls of the corresponding sliding rods 323 are slidably connected to the inner walls of the first groove 221, and the tops of the corresponding sliding rods 323 are fixedly connected to the sliders 222. The inner walls of the two inclined grooves 321 are in slidable contact with the outer walls of the two cylindrical sliders 322 respectively. By setting the clamping and positioning part 3, the centering of concrete components of various sizes can be achieved, ensuring that the components maintain a stable central position during the curing process, and providing the prerequisite for the rotating part 4 to drive the components to be heated evenly.

[0032] The rotating part 4 includes a protective shell 411 fixedly connected to the bottom of the corresponding bracket 114. A motor 412 is fixedly connected to the top of the corresponding protective shell 411. The output shaft of the motor 412 is fixedly connected to a rotating shaft 413 via a coupling. The rotating shaft 413 extends into the corresponding disc 115 and is fixedly connected thereto. By setting the rotating part 4, in conjunction with the infrared lamp 113 of the curing part 1, relatively uniform heating is achieved, avoiding quality problems such as cracks caused by uneven heating of the components, improving the efficiency and quality of electrothermal curing, and ensuring that the strength and performance of the concrete components meet the standards after curing.

[0033] In use, first open the two hinged partition doors 112 on the front side of the casing 111, place the concrete component to be cured on the disc 115 supported by the two brackets 114 on the inner wall of the casing 111, ensuring that the component is located between the clamping plates 215 of the two buffer sections 2, then activate the extension of the electric telescopic rod 312 fixed to the inner wall of the front side of the slide groove 2 311, pushing the rectangular slider 313 to slide horizontally along the slide groove 2 311. The two inclined grooves 321 opened on the rectangular slider 313 move synchronously, and the inner wall of the inclined groove 321 slides into contact with the outer wall of the cylindrical slider 322, driving the two cylindrical sliders 322 to move. As the two sliders 222 approach each other, the slide rod 323, which is fixedly connected to the cylindrical slider 322, slides along the connected slide groove 221. The top of the slide rod 323 is fixedly connected to the slider 222. The two sliders 222 move synchronously towards each other in the two slide grooves 221. The two telescopic protective covers 223 fixed to the outer wall of the slider 222 extend to both sides and fit against the inner wall of the slide groove 221. The rectangular plate 211 fixed to the top of the slider 222 moves with the slider 222. The two rectangular plates 211 that approach each other drive the two clamping plates 215 to approach each other in the process and center the component.

[0034] After the two clamping plates 215 are centered, the clamping plates 215 no longer move. The fixing block 212 fixed on the left side of the rectangular plate 211 simultaneously pushes the sliding sealing plate 214 to slide on the inner wall of the rectangular box 213, squeezing the compressed inert gas inside the rectangular box 213. At the same time, the two dampers 216, which are mirror images of the rectangular plate 211 and the clamping plates 215, extend and retract to form a buffer force until the clamping plates 215 adhere to the concrete component and complete the clamping and fixing. Then, the two partition doors 112 are closed, and several infrared lamps 113 in the curing section 1 are activated to perform electrothermal curing on the component through infrared radiation.

[0035] After the infrared lamp 113 is turned on, the rotating part 4 is started, and the motor 412 fixed to the top of the protective shell 411 at the bottom of the bracket 114 is powered on and runs. Its output shaft is fixedly connected to the rotating shaft 413 through a coupling. The rotating shaft 413 extends into the disc 115 and is fixedly connected to it, thereby driving the disc 115 to rotate on the bracket 114, so that the components receive the heat of the infrared lamp 113 evenly. After curing, the infrared lamp 113 and the motor 412 are turned off first. After the disc 115 stops and the component temperature drops to a suitable range, the electric telescopic rod 312 is started to retract in the opposite direction, which drives the rectangular slider 313 to reset. The inclined groove 321 drives the cylindrical slider 322, the sliding rod 323 and the slider 222 to move in the opposite direction. The clamping plate 215 releases the component, the telescopic protective cover 223 retracts and resets, and finally the partition door 112 is opened to take out the cured concrete component.

[0036] It should be noted that the control of the infrared lamp 113, the electric telescopic rod 312 and the motor 412 in this application can all be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be achieved using existing technologies, such as PLC.
