Description

Technical Field

[0001] This invention relates to a curing cabinet, specifically to an intelligent curing system for concrete specimens. Background Technology

[0002] Today, cement concrete is widely used in construction, transportation, and other engineering projects, necessitating sample testing. Before testing, cement concrete specimens must be prepared according to specifications and cured for 28 days in a constant temperature and humidity environment. Current regulations require the construction of a standard curing room in the laboratory, maintaining a constant temperature and humidity environment for the curing of cement concrete specimens. Therefore, temporary curing rooms are often constructed at highway or railway construction sites, and then dismantled after construction. However, this method of using temporary curing rooms not only wastes resources and increases curing costs, but also requires a significant amount of time to construct, extending the construction period and reducing efficiency.

[0003] In addition, existing curing rooms all use multiple sets of storage racks in a closed space, and then place the cement concrete specimens to be cured in each set of storage racks. When it is necessary to put them into or take them out of the curing room, the door of the curing room must be opened in advance, or the air conditioner and atomizer must be turned off, so that the temperature and humidity environment in the curing room reaches a level that is human-resistant, making it easier for personnel to handle the specimens. Since the specimens are heavy and there are many of them, the handling and placement take a lot of time, causing the temperature and humidity parameters of the curing room to deviate from the standard allowable range for a long time, thus adversely affecting the curing effect. Summary of the Invention

[0004] This invention overcomes the shortcomings of existing technologies by providing an intelligent curing system for concrete specimens. This system can be flexibly assembled according to site size and project scale, and the cabinets are reusable, saving curing costs and reducing installation time, thus improving efficiency. Furthermore, the system automatically removes and places concrete specimens into the cabinets, with the cabinet door remaining open for only 8 seconds during each operation to ensure the curing environment is not disrupted. Additionally, the system automatically regulates the temperature and humidity inside the cabinets, keeping the specimens within the specified standard range.

[0005] The technical solution of this invention to solve the problems of the prior art is:

[0006] A smart curing system for concrete specimens includes multiple smart curing cabinets, an inbound / outbound workbench, and a transport device for removing concrete specimens from the smart curing cabinets and transferring them to the inbound / outbound workbench, or removing concrete specimens from the inbound / outbound workbench and transferring them to the smart curing cabinets. Each smart curing cabinet includes a cabinet body, an air conditioning system for regulating the temperature inside the cabinet, and an atomizing system for regulating the humidity inside the cabinet. The cabinet body has multiple grids for storing concrete specimens, with symmetrical support blocks on both sides of each grid for supporting the sides of the support. Each grid has a door at its inlet and outlet. The transport device is used to open the door of the corresponding grid in the cabinet body to remove the concrete specimen stored in that grid, or, during sample collection, to open the door of a designated grid to place the concrete specimen into that grid.

[0007] Preferably, the handling device includes an automatic fork, a handling lifting mechanism for driving the automatic fork to move up and down, and a traveling mechanism for driving the handling lifting mechanism to move to the intelligent maintenance cabinet. The handling lifting mechanism includes a frame, a handling seat mounted on the frame, and a lifting drive mechanism for driving the handling seat to move up and down. The automatic fork is mounted on the handling seat.

[0008] Preferably, the grilles are arranged in a matrix on the cabinet body, and each grille is provided with a cabinet door; all cabinet doors in the same row are installed on the cabinet body by a vertical sliding mechanism; the vertical sliding mechanism includes a slide rail provided on the cabinet body and located on both sides of the cabinet door, and a sliding member provided on both sides of the cabinet door and cooperating with the slide rail; when one set of cabinet doors slides vertically, the cabinet doors in the same row and located above the cabinet doors also slide vertically simultaneously.

[0009] Preferably, the slide rail is provided with a sealing element for sealing each grille to maintain a constant temperature and humidity within the grille; the inner wall of the cabinet is fully wrapped with heat-insulating cotton.

[0010] Preferably, the transport base is provided with cabinet door opening mechanisms on both sides for opening the cabinet door. The cabinet door opening mechanism includes a bracket on the transport base, a lever on the bracket, and a door opening drive mechanism for driving the lever to extend or retract. The cabinet door is provided with a handle. When the cabinet door needs to be opened, the door opening drive mechanism drives the lever to extend, and the transport lifting mechanism drives the transport base to rise, so that the lever lifts the handle on the cabinet door to be opened, thereby pushing the cabinet door and all cabinet doors in the same row and above the cabinet door to rise, thereby opening the cabinet door. When the cabinet door needs to be closed, the door opening drive mechanism drives the lever to retract, so that all the previously raised cabinet doors slide down under their own gravity to close.

[0011] Preferably, the walking mechanism includes a track set on the ground and a mobile vehicle set on the track, wherein the frame is mounted on the mobile vehicle; multiple sets of intelligent maintenance cabinets are respectively set on both sides of the track.

[0012] Preferably, the inbound / outbound workbench is equipped with a pallet positioning mechanism, which includes two sets of positioning blocks arranged in parallel, with grooves on opposite sides of the two sets of positioning blocks; the grooves on the two sets of positioning blocks together form a positioning groove for positioning the pallet in the X-axis direction; when the pallet is placed on the positioning groove, the gap between the pallet and the surface of the inbound / outbound workbench can accommodate the automatic forks to extend and retract; the inbound / outbound workbench is also equipped with a pallet limiting mechanism, which includes a limiting block located at the end of the two sets of positioning blocks away from the handling device, wherein the two ends of the limiting block are respectively connected to the two sets of positioning blocks.

[0013] Preferably, each smart maintenance cabinet is connected to the ground by a detachable structure; each smart maintenance cabinet is also equipped with a moving mechanism at the bottom.

[0014] Preferably, the bottom surface of the tray is provided with a protrusion, and the concrete specimen is supported by the protrusion; there is a gap between the bottom surface of the concrete specimen and the bottom surface of the tray.

[0015] Preferably, it also includes a size measuring device for measuring the size of the concrete specimen. When the size measuring device measures that the size of the concrete specimen meets the standard, the concrete specimen is transported to a tray located in the inbound / outbound workbench.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The intelligent curing system for concrete specimens of the present invention is equipped with multiple intelligent curing cabinets, and each intelligent curing cabinet can store multiple sets of concrete specimens. Therefore, an appropriate number of intelligent curing cabinets can be selected according to the size of the site and the scale of the project, thereby achieving flexible assembly according to local conditions. Moreover, the intelligent curing cabinets can be reused. That is, after the project is completed, the disassembled intelligent curing cabinets can be transported to the next project construction site for reuse, which not only saves curing costs, but also saves the time of building intelligent curing cabinets compared with the existing method of building temporary curing rooms, which is conducive to improving efficiency.

[0018] 2. In the intelligent curing system for concrete specimens of the present invention, the concrete specimens on the inbound / outbound workbench can be moved into the cabinet of the intelligent curing cabinet by a conveying device, and the concrete specimens in the intelligent curing cabinet can also be taken out and moved into the inbound / outbound workbench, which has a higher degree of automation and thus greatly improves work efficiency.

[0019] 3. Each intelligent curing cabinet in the intelligent curing system for concrete specimens of the present invention is equipped with an air conditioning system and a misting system. The air conditioning system and the misting system can automatically adjust the temperature and humidity inside the intelligent curing cabinet, thereby ensuring that the concrete specimens inside each intelligent curing cabinet are in a constant temperature and humidity state. Furthermore, since there are multiple intelligent curing cabinets, each intelligent curing cabinet can hold the same batch of concrete specimens. When it is necessary to remove or put in concrete specimens, it will not have any adverse effects on the concrete specimens inside other intelligent curing cabinets, thus ensuring the curing effect.

[0030] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0031] See Figures 1-11 The intelligent curing system for concrete specimens of the present invention includes multiple intelligent curing cabinets 1, an inbound / outbound workbench 3, and a transport device 2 for removing concrete specimens from the intelligent curing cabinets 1 and delivering them to the inbound / outbound workbench 3, or for transporting concrete specimens from the inbound / outbound workbench 3 and delivering them to the intelligent curing cabinets 1. Each intelligent curing cabinet 1 is detachably connected to the ground (e.g., by bolts), and each intelligent curing cabinet 1 has a movable mechanism at its bottom for transferring disassembled cabinets 1. Each intelligent curing cabinet 1 includes a cabinet body 101 and an empty space within the cabinet body 101. The system includes an air conditioning system and an atomization system; the cabinet 101 is equipped with a cabinet door 102, and the cabinet 101 contains multiple grids for storing concrete specimens; L-shaped support blocks 105 are symmetrically arranged on both sides of the grids to support the sides of the trays; the air conditioning system is used to regulate the temperature inside the cabinet 101; the atomization system is used to regulate the humidity inside the cabinet 101; in order to achieve airflow circulation inside the cabinet 101 and thus maintain a stable temperature and humidity inside the cabinet 101 for a long time, a circulation pipe is installed inside the cabinet 101 to keep the temperature and humidity inside the cabinet 101 constant. In addition, control buttons for electrical equipment, air conditioning system, and atomization system, as well as a touch screen for concrete specimen curing management, are installed on the front of the cabinet 101. The handling device 2 includes an automatic fork 5, a handling lifting mechanism 9 for driving the automatic fork 5 to move up and down, and a traveling mechanism for driving the handling lifting mechanism 9 to move to the intelligent curing cabinet 1. The handling lifting mechanism 9 includes a frame, a handling seat mounted on the frame, and a lifting drive mechanism for driving the handling seat to move up and down. The automatic fork 5 is mounted on the handling seat. The lifting drive mechanism adopts a driving method combining a lifting motor and a screw transmission mechanism. The traveling mechanism includes a track 8 set on the ground and a mobile vehicle 7 set on the track 8. The frame is mounted on the mobile vehicle 7. The traveling wheels on the mobile vehicle 7 cooperate with the track 8. Multiple sets of intelligent curing cabinets 1 are respectively arranged on both sides of the track 8.

[0032] In this embodiment, the automatic fork 5 can be implemented using an existing bidirectional automatic telescopic fork, enabling the automatic fork 5 to remove and place concrete specimens from the intelligent curing cabinets 1 on both sides of the track 8; in addition, the mobile vehicle body 7 can also be implemented using an existing mobile walking mechanism, and the mobile vehicle body 7 is equipped with a control box 10 for controlling the automatic fork 5, the handling and lifting mechanism 9, the walking mechanism, and the cabinet door opening mechanism mentioned below.

[0033] See Figures 1-11 The inbound / outbound workbench 3 can be divided into two sets, one for inbound and the other for outbound. Each workbench 3 is equipped with a pallet positioning mechanism, which includes a support frame 301 and two sets of parallel positioning blocks 302 mounted on the support frame 301. Grooves 303 are provided on opposite sides of the two sets of positioning blocks 302. These grooves 303 together form a positioning groove for positioning the pallet 4 in the X-axis direction (i.e., both sides of the pallet 4 along its width). When the pallet 4 is placed on the positioning groove, the gap between the pallet 4 and the workbench 3 allows the automatic forks 5 to extend and retract. Furthermore, the workbench 3 is equipped with a pallet limiting mechanism, which includes a limiting block 304 located at the end of the two sets of positioning blocks 302 furthest from the transport device 2, for limiting the side of the pallet 4 furthest from the transport device 2 along its length. With the above settings, when the pallet 4 is delivered to the inbound / outbound workbench 3, the three sides of the pallet 4 can be positioned to ensure its positional accuracy before handling, so as to facilitate the automatic fork 5 in the handling device 2 to accurately transport the pallet 4 and the concrete specimen on the pallet 4 into the cabinet 101 of the intelligent curing cabinet 1.

[0034] See Figures 1-11 The grilles are arranged in a matrix on the cabinet 101, and each grille is provided with a cabinet door 102. All cabinet doors 102 in the same row are mounted on the cabinet 101 via a vertical sliding mechanism 104. The vertical sliding mechanism 104 includes slide rails disposed on the cabinet 101 and located on both sides of the cabinet door 102, and sliding members disposed on both sides of the cabinet door 102 that cooperate with the slide rails. The slide rails are provided with sealing members to seal each grille, thereby maintaining the temperature and humidity inside the grille. When one set of cabinet doors 102 slides vertically, the cabinet doors 102 in the same row and located above it also slide vertically simultaneously.

[0035] To enable the opening and closing of the cabinet door 102, cabinet door opening mechanisms 6 are provided on both sides of the transport base for opening the cabinet door 102. Each cabinet door opening mechanism 6 includes a bracket 601 mounted on the transport base, a lever 602 mounted on the bracket 601, and an opening drive mechanism 603 for driving the lever 602 to extend or retract. The cabinet door 102 is provided with a handle 103. When the cabinet door 102 needs to be opened, the opening drive mechanism 603 drives the lever 602 to extend, so that the lever 602 is directly below the handle 103. The transport lifting mechanism 9 then raises the transport base, causing the lever 602 to lift the handle 103, thereby pushing the handle... The cabinet door 102 connected to the hand 103, as well as all cabinet doors 102 in the same row and above the cabinet door 102, are raised to open the cabinet door 102. During the upward opening of the cabinet door 103, the automatic fork 5 extends and, as the transport seat continues to rise, the automatic fork 5 supports the pallet 4. When the cabinet door 102 is opened to the point that the pallet 4 and the concrete specimen inside the pallet 4 can be easily removed, the automatic fork 5 resets (i.e. retracts) to remove the pallet 4 along with the concrete specimen on the pallet 4. Subsequently, the door opening drive mechanism 603 drives the lever 602 to retract, causing all the previously raised cabinet doors 102 to slide down under their own gravity to close the inlet and outlet of the grille. Similarly, when the pallet 4 on the automatic fork 5, along with the concrete specimen on the pallet 4, is placed onto the grid of the cabinet 101, the automatic fork 5 extends when the cabinet door 103 is opened to allow the pallet 4 and the concrete specimen on the pallet 4 to pass through, thereby placing the pallet 4 and the concrete specimen on the pallet 4 into the grid of the cabinet 101. Then, the transport lifting mechanism 9 drives the transport seat to move downward. When the pallet 4 is supported on the grid of the cabinet 101, the automatic fork 5 resets (i.e. retracts). Subsequently, the door opening drive mechanism 603 drives the lever 602 to retract, causing all the previously raised cabinet doors 102 to slide down under their own weight to close the entrance and exit of the grid.

[0036] See Figures 1-11 The intelligent curing system for concrete specimens of the present invention also includes a coding device that records the position of each placed or removed concrete specimen. When the curing of the concrete specimen is completed, the control system will automatically remind the staff. When the transport device 2 takes out the concrete specimen, the coding device will mark the empty grid. When the concrete specimen needs to be put into the warehouse for curing, the control system will control the transport device 2 to transport the concrete specimen to the empty grid.

[0037] See Figures 1-11The concrete specimen is placed in the tray 4. In this embodiment, the tray 4 is designed with three compartments, with one concrete specimen placed in each compartment. The spacing between two adjacent concrete specimens is maintained between 10mm and 20mm. At the same time, there are small protrusions 401 on each side and bottom of the tray 4, so that there is a gap between the concrete specimen and the edge of the tray 4 to facilitate the air circulation after atomization.

[0038] See Figures 1-11 The inbound / outbound workbench is equipped with a dimensional measuring device 15 for measuring the dimensions of concrete specimens. Once the dimensional measuring device 15 measures the dimensions of the concrete specimen to be within the standard range, the specimen is transferred to a tray 4 located on the inbound / outbound workbench. The dimensional measuring device 15 includes a workbench, a dimensional positioning platform 13 mounted on the workbench, an X-axis position adjustment mechanism 11 for adjusting the position of the concrete specimen on the X-axis, a Y-axis position adjustment mechanism 12 for adjusting the position of the concrete specimen on the Y-axis, and a measuring sensor 14 for measuring the length, width, and height of the adjusted concrete specimen. The dimensional positioning platform 13 consists of a bottom support roller and two positioning baffles. The included angle between the two positioning baffles is 90 degrees. Three sets of measuring sensors 14 are positioned on three different sides (front, side, and top) of the concrete specimen located on the dimensional positioning platform 13. The absolute value of the difference between the distance between the measuring sensor 14 and the concrete specimen and the distance between the measuring sensor 14 and the bottom support roller (or the two positioning baffles) is the height (or length and width) of the concrete specimen, thus obtaining the dimensions of the concrete specimen. Furthermore, when placing the concrete specimen onto the dimensional positioning platform 13, the orientation of the concrete specimen needs to be adjusted using the X-axis position adjustment mechanism 11 and the Y-axis position adjustment mechanism 12, so that the two vertical sides of the concrete specimen are respectively attached to the two positioning baffles. Then, the dimensions are measured.

[0039] In this embodiment, the X-axis position adjustment mechanism 11 and the Y-axis position adjustment mechanism 12 use cylinders to push the push plate to move, thereby pushing the side of the concrete specimen to fit against the two positioning baffles.

[0040] See Figures 1-11 The inner wall of the cabinet 101 is fully wrapped with heat insulation cotton to further improve the heat preservation effect.

[0041] See Figures 1-11 The intelligent curing system for concrete specimens of the present invention also has the following advantages:

[0042] (1) To achieve fully automated, unattended management of concrete specimens from entry to exit from the warehouse;

[0043] The entry and exit of concrete specimens from the warehouse can be managed automatically by the information system without the need for manual handling, placement, or locating. This saves a lot of manpower, material resources, and time.

[0044] (2) Ensure that concrete specimens are cured according to specifications and reduce human interference;

[0045] Traditionally, the curing room door needs to be opened before each entry and exit to disperse the fog, a process that takes about an hour and disrupts the curing environment. The intelligent curing system for concrete specimens of this invention automates the entire process, requiring only the opening of a single grille for about 10 seconds each time specimens are stored or retrieved, thus preventing any disruption to the curing environment.

[0046] (3) To achieve full life cycle monitoring of the specimens;

[0047] Equipped with a warehouse management system, it provides information management for the entire life cycle of concrete specimens. The entire process of concrete specimens, from preparation, storage, curing to testing, is managed by the system. Once the specimens are stored, they cannot be taken out if the curing period is insufficient, thus avoiding human interference.

[0048] (4) The number of intelligent maintenance cabinets can be flexibly increased to optimize the use of funds;

[0049] Because each smart maintenance cabinet 1 has its own air conditioning, atomization, and circulation device, each cabinet 101 is an independent system. It can be configured according to the site conditions, project scale, and project progress to maintain a reasonable number of cabinets 101. For example, 1-2 cabinets can be configured at the beginning of the project, 15-20 cabinets can be configured during the peak period of the project, and 1-2 cabinets can be retained in the later stage of the project. This can optimize the use of funds.

[0050] (5) The intelligent maintenance cabinet 1 can be reused, saving costs;

[0051] The intelligent maintenance cabinet 1 has a lifespan that can meet the needs of two or more projects for continuous use. After one project is completed, it can be directly moved to a new project for continued use, thus improving utilization.

[0052] (6) It achieves rational use of space, reduces the use of air conditioning, and saves energy and protects the environment.

[0053] The above are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
