[0031] Example:

[0032] like Figure 1-3 As shown, this embodiment provides a concrete test block curing frame device, including a curing frame body, a lifting device, a support platform 6, a lifting platform, a limiting device, a pallet component 12, and a controller;

[0033] The number of support platforms 6 is two or more, and they are arranged parallel to each other along the height direction of the maintenance frame.

[0034] The lifting device is installed on the maintenance frame. The lifting drive end of the lifting device is connected to the lifting platform and can drive the lifting platform to move along the height direction.

[0035] The limiting device is located on the maintenance frame and corresponds to the position of the support platform 6. The limiting device is equipped with a limiting drive end that can move relative to the maintenance frame. The lifting platform is equipped with a limiting part that can cooperate with the limiting drive end.

[0036] The support platform 6 and the lifting platform are provided with guide rails that can slide and cooperate with the pallet 12. When the lifting platform and the support platform 6 are aligned, the guide rails on the support platform 6 are aligned with the guide rails on the lifting platform.

[0037] The controller is located on the maintenance frame and is electrically connected to the lifting device and the limit device.

[0038] The concrete specimen curing rack device of this embodiment has several support platforms 6 to increase the number of concrete specimens 14 that can be placed, thereby improving space utilization. At the same time, the lifting device, in conjunction with the structure of the lifting platform, allows the operator to easily adjust the pallet 12 to move relative to the support platform 6. The limiting device ensures that the lifting platform stays stably on each support platform 6, preventing the lifting platform from shaking during the handling of the concrete specimens 14, thus ensuring the safe placement and retrieval of the concrete specimens 14. Finally, the guide rail facilitates the relative movement of the pallet 12 on the support platform 6 and the lifting platform, making it convenient to place and retrieve the concrete specimens 14, and ensuring safe and convenient transportation.

[0039] The specific structure of the maintenance frame in this embodiment is as follows:

[0040] The system includes a base plate 2, columns 3, and pulleys 1. The columns 3 are vertically positioned at the four corners of the top surface of the base plate 2, and the pulleys 1 are positioned at the four corners of the bottom surface of the base plate 2. A support platform 6 is connected to the columns 3. In this embodiment, there are six support platforms 6 connected to the columns 3.

[0041] In the above structure, the base plate 2 and the column 3 of the curing frame can be made of aluminum alloy, which is structurally stable, lightweight, and corrosion-resistant. This material selection ensures the strength of the curing frame while improving its ease of movement and durability, ensuring that the curing frame maintains good performance and adapts to different curing environments during long-term use. The pulley component 1 specifically uses high-strength, pressure-resistant plastic casters with locking mechanisms, thus ensuring the stability of the curing frame structure and facilitating overall movement.

[0042] The guide rail section of this embodiment includes two parallel guide rail grooves, and the bottom of the tray 12 is provided with a roller 11 that cooperates with the guide rail groove.

[0043] Specifically, there are three guide rail sections, with each support platform 6 having three guide rail sections. In the above structure, each guide rail section on each support platform 6 is equipped with three tray pieces 12. The entire curing frame can hold 54 concrete specimens 14, which greatly increases the number of curing specimens compared to existing partial curing frames and improves curing efficiency.

[0044] The lifting device in this embodiment includes a lifting rotary motor 10, a horizontal rotating shaft 9, a vertical rotating shaft 8, a longitudinal transmission gear 4, and a horizontal transmission gear 5. The horizontal rotating shaft 9 and the vertical rotating shaft 8 are rotatably mounted on the base plate 2 of the maintenance frame. The longitudinal transmission gear 4 is mounted on the vertical rotating shaft 8, and the horizontal transmission gear 5 is mounted on the horizontal rotating shaft 9. The longitudinal transmission gear 4 and the horizontal transmission gear 5 mesh with each other. The drive end of the lifting rotary motor 10 is connected to the horizontal rotating shaft 9. The lifting platform is sleeved on the vertical rotating shaft 8 and threadedly engaged with the vertical rotating shaft 8. The lifting platform is slidably engaged with the maintenance frame column 3.

[0045] Specifically, the lifting platform includes a lifting platform base plate 16, a lifting bushing 7, and a lifting structure frame 15. The lifting bushing 7 is threadedly engaged with the vertical rotation shaft 8. The lifting structure frame 15 is connected to the lifting platform base plate 16 and the lifting bushing 7 respectively. The guide rail is located on the lifting platform base plate 16.

[0046] The lifting and rotating motor 10 rotates the horizontal rotating shaft 9, thereby rotating the vertical rotating shaft 8. The gear meshing structure and the threaded engagement structure mentioned above enable the lifting platform to move stably on the vertical rotating shaft 8.

[0047] The limiting device in this embodiment includes a limiting drive cylinder 18 and a limiting buckle 19. The limiting buckle 19 is connected to the drive end of the limiting drive cylinder 18, and the limiting part of the lifting platform is a limiting hole 20.

[0048] In this embodiment, the controller can be a PLC controller 17, and a sensor is installed on the maintenance frame and at the position corresponding to the support platform 6. The sensor is electrically connected to the PLC controller 17. When the lifting platform reaches the designated floor, the sensor triggers the information and feeds it back to the controller. The controller controls the lifting device to stop lifting to prevent the platform from being damaged due to excessive lifting. At the same time, it controls the limit buckle 19 of the limit device to pop out and cooperate with the limit hole 20 of the lifting platform.

[0049] The support platform 6 in this embodiment has several perforated holes, and the total area of ​​these perforated holes accounts for 50%-70% of the area of ​​the support platform 6. This perforated structure ensures sufficient airflow and curing medium. The design of the perforated structure not only facilitates the uniform distribution of humidity and temperature within the curing chamber to all surfaces of the test block, but also allows for the timely drainage of accumulated water or condensation generated during the curing process, preventing the test block from being soaked in water and affecting the curing effect.

[0050] The guide rail section of this embodiment includes two parallel guide rail grooves. The bottom of the tray 12 is provided with rollers 11 that cooperate with the guide rail grooves. At the same time, limit blocks are provided at both ends of the guide rail section. The limit blocks can be rubber blocks or metal blocks to ensure that the tray 12 moves within a specified range and to prevent the tray 12 from accidentally slipping off during the sliding process.

[0051] In this embodiment, the tray 12 is provided with a pad 13, and the pad 13 is provided with anti-slip ridges. The above structure increases the friction between the concrete specimen 14 and the pad 13, preventing the concrete specimen 14 from sliding on the tray 12.

[0052] In summary, the advantages of this embodiment are as follows:

[0053] 1. The curing frame adopts a frame structure, combined with the spatial layout of the multi-layered support platform 6, which increases the number of curing specimens and improves curing efficiency.

[0054] 2. The lifting device, limiting device, and guide rail structure ensure that the specimens are placed and moved stably on the curing frame. At the same time, the hollow structure provides good temperature and humidity exchange, and also reduces the tedious actions of operators in moving the concrete specimens 14, thus improving curing efficiency.

[0055] 3. The controller in this embodiment can realize the automated movement of the lifting platform, ensuring that operators can conveniently and quickly transport the specimens to the designated height.

[0056] 4. The support platform 6 and the lifting platform are equipped with guide rails, which can enable the pallet 12 to move between the support platform 6 and the lifting platform. At the same time, the pallet 12 on the support platform 6 at one of the positions can be moved, which can meet the needs of different near-term storage and greatly improve the maintenance efficiency.

[0057] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
