They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0029] The features and performance of this application will be further described in detail below with reference to the embodiments.

[0030] like Figure 1As shown, this application provides an intelligent curing box structure for antifreeze testing, which can provide auxiliary functions for the testing of concrete mixed with antifreeze. Its structure is compact and easy to operate, and it can smoothly and quickly transfer the concrete mixed with antifreeze from the curing area to the freezing area, avoiding deformation and damage to the test blocks caused by manual handling.

[0031] It mainly includes: the top seat of the curing box 1, the main body of the curing box 2, and the door of the curing box 3;

[0032] The upper and lower parts of the inner cavity of the curing box body 2 are respectively provided with a freezing zone 17 and a curing zone 19, and a reserved slot 20 is provided at the junction of the freezing zone 17 and the curing zone 19. A detachable heat insulation board 21 is installed in the reserved slot 20. The freezing zone 17 is provided with a temperature and humidity sensor 8 and a freezing device 22 (specifically an air conditioning refrigeration device in this example). The curing zone 19 is provided with a temperature and humidity sensor 9 and multiple sets of heating tubes 23. The bottom of the curing box body 2 is provided with a hydraulic lifting device 12. A lifting device tray 11 is installed on the top of the hydraulic lifting device 12. A double-sided retractable test block shelf 14 is provided on the lifting device tray 11. The double-sided retractable test block shelf 14 is used to place concrete test blocks 15 mixed with antifreeze.

[0033] like Figure 2 As shown, an observation window 4 is installed on the door 3 of the maintenance box, corresponding to the position of the maintenance area 19. A touch screen controller 13 is installed on the outside of the door 3 of the maintenance box. The touch screen controller 13 is equipped with a lifting device up button, a lifting device down button, a maintenance start and stop button, and a freezer start and stop button.

[0034] Furthermore, a sealing strip 16 is installed on the inner side of the maintenance box door 3 corresponding to the reserved slot 20, and a sealing rubber edge 18 is provided on the outer edge of the maintenance box door 3.

[0035] like Figures 3-4 As shown, the double-sided retractable test block rack 14 includes a fixed plate 141 whose size is adapted to the inner wall size of the curing area 19. Telescopic plates 142 are slidably inserted on both sides of the fixed plate 141, and the telescopic plates 142 on both sides are connected to the fixed plate 141 by telescopic springs 143.

[0036] Furthermore, the width of the telescopic plate 142 is one-third of the width of the fixed plate 141, and the telescopic plates 142 on both sides can be completely retracted into the fixed plate 141. When the telescopic plate 142 is retracted into the fixed plate 141, the telescopic spring 143 is in a compressed state.

[0037] Furthermore, the upper surfaces of the fixed plate 141 and the telescopic plate 142 are provided with anti-slip teeth 144, and the fixed plate 141, the telescopic plate 142 and the detachable heat insulation plate 21 are all made of ceramic fiber heat insulation material.

[0038] When the double-sided retractable test block rack 14 is in the curing area 19, the spring is compressed and automatically shortens, so that the telescopic plates 142 on both sides are completely retracted into the fixed plate 141.

[0039] When the hydraulic lifting device pushes the shelf up to the reserved slot 20, the telescopic plates 142 on both sides pop out under the thrust of the compression spring, so that the shelf is locked in the reserved slot 20. At the same time, the concrete test block 15 with antifreeze is sent to the freezing zone 17, and the freezing zone 17 and the curing zone 19 are separated again.

[0040] Furthermore, a signal transceiver 6, an alarm 7, and a running indicator light 10 are installed on the top seat 1 of the maintenance box, and a lighting lamp 5 is installed inside the main body 2 of the maintenance box.

[0041] Furthermore, the lighting lamp 5, alarm 7, temperature and humidity sensor 1 8, temperature and humidity sensor 2 9, operation indicator 10, hydraulic lifting device 12, refrigeration device 22 and heating tube 23 are all electrically connected to the signal transceiver 6 through the internal wiring of the enclosure, and the signal transceiver 6 is wirelessly connected to the touch screen controller 13.

[0042] The specific working principle is as follows:

[0043] 1) Curing process: The tester first places the concrete test block to be tested with antifreeze on the double-sided retractable test block shelf, and then places the shelf on the lifting device tray at the bottom of the curing area. Then, the removable insulation board is installed and the door of the curing box is closed to separate the curing area from the freezing area inside the box. At the same time, the heating tube is turned on through the touch screen controller to carry out the curing work of the concrete test block.

[0044] 2) Freezing process: When the concrete test blocks need to be sent to the freezing zone after curing, the tester opens the curing chamber door and takes out the detachable insulation board. Then, the tester starts the hydraulic lifting device through the touch screen controller to lift the shelf to the reserved slot at the boundary between the freezing zone and the curing zone. The double-sided retractable test block shelf is then locked into the reserved slot. While sending the concrete test blocks to the freezing zone, the freezing zone and the curing zone are separated again. Then, the curing chamber door is closed and the freezing device is turned on through the touch screen controller to carry out the freezing of the concrete test blocks.

[0045] Optionally, the detachable insulation board 21 can be replaced with an electrically retractable and closable insulation board symmetrically arranged on both sides below the reserved slot 20. During the curing of the concrete test block, the insulation board is used to separate the curing area 19 from the freezing area 17. When the concrete test block needs to be transferred to the freezing area, the closable insulation boards on both sides are retracted into the curing box to ensure that the lifting device can push the shelf through smoothly.

[0046] Furthermore, all parts of this application that are not described in detail are the same as or implemented using existing technology.

[0047] In summary:

[0048] 1. The present invention provides an intelligent curing box structure for antifreeze testing. Through the reasonable arrangement of the curing box top, curing box door and various components inside the curing box body, the internal cavity of the box is divided into a freezing zone and a curing zone. After the insulation board is removed, with the help of the hydraulic lifting device and the double-sided retractable test block rack, the concrete to be tested with antifreeze can be transferred smoothly and quickly from the curing zone to the freezing zone.
