[0002] Stability refers to whether the volume change of cement or concrete is uniform during the hardening process, and is one of the important indicators for evaluating its quality. The concrete boiling box is a device used for cement or concrete stability testing. It is widely used in construction projects. By conducting heating experiments on materials such as cement or concrete, it simulates the performance changes of cement or concrete in a high temperature environment, thereby evaluating its quality and stability. The working principle of the concrete boiling box is to place the cement or concrete test block on a rack, immerse the rack in water, and boil the water through electric heating, thereby generating a continuous high temperature and high pressure environment, and observing the physical and chemical changes of the cement or concrete test block under this condition, thereby evaluating its stability.

[0003] After each use of the existing concrete boiling box, the cement or concrete test block needs to be manually taken out of the box, which is time-consuming and laborious, and can easily burn the user. Only one cement or concrete test block can be tested at a time, and multiple cement or concrete test blocks cannot be tested continuously. When the number of test blocks to be tested is large, the detection efficiency is low.

[0004] Therefore, it is necessary to propose a concrete boiling box for concrete testing to solve the technical problems existing in the existing concrete testing process. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) By setting a switching rotating assembly and a test block placement assembly, when in use, multiple cement or concrete test blocks can be placed on different placement grids according to actual needs. The rotating motor drives the rotating rod to rotate, so that the control telescopic rod drives the placement frame and the placement grid to move. When one of the control telescopic rods rotates to the bottom, the control telescopic rod automatically starts and drives the test block placement assembly to descend. The placement grid enters the boiling box to perform boiling detection on the cement or concrete test block. After the detection is completed, the control telescopic rod automatically drives the test block placement assembly to rise and leave the boiling box, and the test block placement assembly at the next adjacent position is moved to the bottom by rotating the rotating rod. The detection operation is repeated to realize the automation of the test block placement and removal operation, and achieve the technical effect of continuous detection of multiple test blocks;

[0016] (2) When the rotating rod rotates, the switching contact piece can contact with the positioning contact piece respectively. The positioning contact piece is arranged at the lower end of the circular moving track of the switching contact piece. Therefore, when the switching contact piece and the positioning contact piece are in contact, the control telescopic rod corresponding to the switching contact piece will move to the lowermost position. At this time, the main controller automatically starts the control telescopic rod according to the signal of the switching contact piece and the positioning contact piece contacting, thereby realizing the accurate positioning effect of the test block placement component;

[0017] (3) When the telescopic rod is controlled to drive the test block placement assembly into the boiling box, the closed box cover can automatically contact the upper edge of the boiling box, thereby ensuring the closure of the boiling box during the test process. When testing cement or concrete test blocks of different sizes, the telescopic rod can be controlled to drive the placement grille to extend into different height positions inside the boiling box to ensure that cement or concrete test blocks of different sizes can be boiled at a suitable water depth. In the process of adjusting the height of the test block placement assembly driven by the telescopic rod, the closed box cover will slide on the side wall of the support rod, and the reset spring will always apply a downward force to the closed box cover to ensure that the closed box cover always maintains a closed effect on the boiling box;

[0018] (4) The placement frame is rotatably connected to the support rod. When the rotating rod rotates and drives each test block placement assembly to move, the placement frame and the isolation box grate can always remain stable under the action of gravity to prevent the test block placed on the placement grid from falling out due to the tilt of the placement grid;

[0019] (5) The isolation box grate is set below the placement frame to prevent the fragments of the test block from remaining in the boiling box due to the explosion and breakage caused by heating. The isolation box grate can intercept the fragments, and the fragments are automatically moved out of the boiling box together with the isolation box grate, reducing the steps of manual cleaning;

[0020] (6) A friction damping plate is provided at the rotation position between the support rod and the placement frame. The friction damping plate serves to reduce the possibility of swinging of the placement frame when it rotates relative to the support rod, thereby preventing the test block from falling out due to excessive swinging of the placement frame and the placement grid during the movement of the test block placement assembly.

The support rod 41 is symmetrically arranged at the output end of the control telescopic rod 32, the placement frame 42 is arranged between the ends of the support rod 41, and the ends of the support rod 41 are respectively rotatably arranged at the middle position of the side walls at both ends of the placement frame 42. The isolation box grate 43 is fixedly arranged below the placement frame 42;

[0035] The number of the control telescopic rod 32 and the number of the test block placement assembly 4 are four respectively, the side wall of the support rod 41 is sleeved with a closed box cover 44, the closed box cover 44 is slidably arranged along the support rod 41, the inner lower edge of the placement frame 42 is provided with a placement grid 421 in a linear array, and the lower wall of the isolation box grate 43 is evenly provided with box grate holes 431;

[0036] An insulating sealing strip 441 is provided at the edge of the closed box cover 44, a return spring 442 is symmetrically connected between the side wall of the closed box cover 44 close to the control telescopic rod 32 and one end of the support rod 41 close to the control telescopic rod 32, and a friction damping plate 45 is provided at the rotating connection axis position of the support rod 41 and the placement frame 42.

[0037] A main controller 5 is provided on one side of the supporting frame 1, and a control panel 51 is provided on the upper end of the main controller 5. The rotating motor 12, the heating tube 23, the switching contact piece 3111, the control telescopic rod 32 and the control panel 51 are electrically connected to the main controller 5 respectively.

[0038] Working principle and workflow: In the initial state, the device Figure 1As shown, one of the test block placement components 4 is located at the bottom. The user can place multiple cement or concrete test blocks on the placement grids 421 in different test block placement components 4 according to actual needs. At this time, the user starts the device through the control panel 51, and the main controller 5 automatically controls the control telescopic rod 32 at the bottom to automatically start, and the control telescopic rod 32 drives the test block placement component 4 to descend, so that the placement grid 421 enters the boiling box 2, and the test block is automatically placed in the boiling box 2 to wait for detection. At the same time, the closed box cover 44 descends with the support rod 41 until the edge of the closed box cover 44 touches the boiling box 2, so as to achieve the automatic sealing effect of the boiling box 2, and the heat insulation sealing strip 441 plays a heat insulation role to reduce the heat loss in the boiling box 2;

[0039] The user connects the water inlet 21 to an external water pipe, and the external water pipe introduces the external water source into the boiling box 2 through the water inlet 21 until the water level in the boiling box 2 reaches a suitable height and then stops adding water. The water inlet 21 and the water outlet 22 are respectively movably provided with closing covers. When the water inlet 21 or the water outlet 22 is not in use, the closing covers serve to temporarily close the water inlet 21 or the water outlet 22.

[0040] The user starts the detection step through the main controller 5, and the heating tube 23 is automatically powered on to heat the water in the boiling box 2. At this time, the test block starts the boiling detection process. The user can set the detection time through the control panel 51. When the preset time is reached, the control telescopic rod 32 will automatically start, driving the test block placement component 4 to rise and leave the boiling box 2. The test block completes a boiling test, realizing the automation of the test block placement and removal operation;

[0041] After one of the test blocks is detected, the main controller 5 will automatically start the rotating motor 12, and the rotating motor 12 drives the rotating rod 31 to rotate, so that the control telescopic rod 32 drives the placement frame 42 and the placement grid 421 to move, and the placement frame 42 is rotatably connected to the supporting rod 41. When the rotating rod 31 rotates and drives each test block placement assembly 4 to move, the placement frame 42 and the isolation box grate 43 can always maintain a stable state under the action of gravity, so as to prevent the test block placed on the placement grid 421 from falling out due to the inclination of the placement grid 421. The test block placement assembly 4 on which the test block after the detection is placed is moved away from the top of the boiling box 2, and another adjacent test block placement assembly 4 will move to the top of the boiling box 2 with the rotation of the control telescopic rod 32. At this time, the control telescopic rod 32 is automatically started, and the test block placement assembly 4 is placed in the boiling box 2, and the above-mentioned detection process is repeated, thereby achieving the technical effect of continuous detection of multiple test blocks.

[0042] When the rotating rod 31 rotates, the switching contact 3111 can contact with the positioning contact 111 respectively. The positioning contact 111 is set at the lower end of the circular moving trajectory of the switching contact 3111. Therefore, when the switching contact 3111 and the positioning contact 111 are in contact, the control telescopic rod 32 corresponding to the switching contact 3111 will move to the lowermost position, and at this time the main controller 5 automatically starts the control telescopic rod 32 according to the signal of the switching contact 3111 contacting with the positioning contact 111, thereby achieving the accurate positioning effect of the test block placement component 4.

[0043] When the control telescopic rod 32 drives the test block placement assembly 4 to enter the boiling box 2, the closed box cover 44 can automatically contact the upper edge of the boiling box 2, thereby ensuring the sealing of the boiling box 2 during the detection process. When testing cement or concrete test blocks of different sizes, the control telescopic rod 32 can drive the placement grille 421 to extend into different height positions inside the boiling box 2 to ensure that cement or concrete test blocks of different sizes can be boiled at a suitable water depth. In the process of controlling the telescopic rod 32 to drive the test block placement assembly 4 to adjust its height, the closed box cover 44 will slide on the side wall of the support rod 41, and the return spring 442 will always apply a downward force to the closed box cover 44, ensuring that the closed box cover 44 always keeps a closed effect on the boiling box 2.

[0044] The isolation box grate 43 is arranged below the placement frame 42 to prevent the fragments produced by the explosion and breakage of the test block due to heating from remaining in the boiling box 2. The isolation box grate 43 can intercept the fragments, and the fragments are automatically moved out of the boiling box 2 together with the isolation box grate 43, thereby reducing the steps of manual cleaning; a friction damping plate 45 is arranged at the rotation position of the support rod 41 and the placement frame 42, and the friction damping plate 45 plays a role in reducing the possibility of swinging of the placement frame 42 when it rotates relative to the support rod 41, thereby avoiding the problem of the test block falling out due to excessive swinging of the placement frame 42 and the placement grille 421 during the movement of the test block placement assembly 4.

[0045] It should be noted that, in this document, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0046] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
