DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention, so as to have a further understanding of the concept of the present invention, the technical problems solved, the technical features constituting the technical solutions and the technical effects brought about.

[0019] like Figure 1 、 Figure 2 As shown, a concrete test block demoulding device includes a base 20, and the left and right ends of the base 20 are respectively installed with a first hydraulic cylinder 12 and a second hydraulic cylinder 13, and the output ends of the first hydraulic cylinder 12 and the second hydraulic cylinder 13 are respectively installed with a first fixed block 14 and a second fixed block 15; the left end of the support plate 2 is installed on the first fixed block 14, and the right end of the support plate 2 is installed on the second fixed block 15; it also includes an upper pressing plate 1, a left connecting frame and a right connecting frame, the left end of the upper pressing plate 1 is connected to the upper end of the left connecting frame, and the right end of the upper pressing plate 1 is connected to the upper end of the right connecting frame; a test block mold 4 is installed at the bottom of the upper pressing plate 1, and the test block mold 4 is box-shaped, and the bottom of the test block mold 4 is open, and the bottom of the test block mold 4 abuts against the support plate 2.

[0020] The conventional method of demolding the test block is to use an air pump to inject high-pressure gas from the vent hole at the bottom of the test mold to squeeze the test block out of the test mold. However, the high-pressure gas demolding method has the safety risk of high-pressure gas injuring people.

[0021] The improvement of the present utility model is that the top of the test block mold 4 equipped with the test block is fixed to the upper pressing plate 1, and the two ends of the upper pressing plate 1 are respectively connected to the left connecting frame and the right connecting frame, so that the upper pressing plate 1 and the test block mold 4 are in a fixed state. During the molding process of the test block, the bottom is connected to the support plate 2 with a certain degree of adhesion. In addition, the test block itself is heavy. The first hydraulic cylinder 12 and the second hydraulic cylinder 13 are used to drive the support plate 2 to descend, so that a height difference is generated between the test block and the test block mold 4, so that the test block and the test block mold 4 can be separated. During the separation process, the staff stays away from the test block mold 4, which increases safety and avoids personal injury. In addition, the first hydraulic cylinder 12 and the second hydraulic cylinder 13 make the lifting process more stable, which can avoid problems such as unstable lifting and shaking.

[0022] Furthermore, a plurality of cameras 3 are provided at the bottom of the upper pressing plate 1, and the cameras 3 are aimed at the abutment between the support plate 2 and the test block mold 4. The cameras 3 are used to observe abnormal conditions during the demoulding process, and the staff can remotely view the process during the demoulding process.

[0023] Furthermore, the utility model further includes a control cabinet 18, which is connected to the first hydraulic cylinder 12, the second hydraulic cylinder 13, and the camera 3 respectively; the control cabinet 18 controls the extension and retraction of the first hydraulic cylinder 12 and the second hydraulic cylinder 13. A program is set in the control cabinet 18 to determine whether there is an abnormality in the demolding process based on the image detected by the camera 3. When an abnormality occurs, the control cabinet 18 controls the first hydraulic cylinder 12 and the second hydraulic cylinder 13 to stop working, thereby avoiding the danger caused by the first hydraulic cylinder 12 and the second hydraulic cylinder 13 continuing to operate under abnormal conditions. The program set in the control cabinet 18 is an existing program that makes judgments based on the data from the camera 3 and issues corresponding control instructions. The program in the control cabinet 18 is not an improvement point of the present utility model.

[0024] Furthermore, the left connecting frame includes a left stabilizing bar 6, on which a horizontally arranged left pressure plate 7 is mounted, and a left support rod 8 is connected to the left pressure plate 7; the right connecting frame includes a right stabilizing bar 9, on which a horizontally arranged right pressure plate 10 is mounted, and a right support rod 11 is connected to the right pressure plate 10; the left pressure plate 7 and the right pressure plate 10 are respectively located above the travel path of the first fixed block 14 and the second fixed block 15. The left pressure plate 7 and the right pressure plate 10 serve as limiting components for the first fixed block 14 and the second fixed block 15, respectively, and restrict the travel path of the first fixed block 14 and the second fixed block 15 above, so that the first hydraulic cylinder 12 and the second hydraulic cylinder 13 stop after extending to a specific position, thereby ensuring that the upper pressure plate 1 and the support plate 2 reach a fixed height difference, facilitating the molding of the test block in the test block mold 4.

[0025] Furthermore, electromagnets 5 are installed on the tops of the left support rod 8 and the right support rod 11. The left and right ends of the upper pressure plate 1 are iron connecting frames 16. The bottom of the connecting frame 16 is provided with a first groove, and the electromagnet 5 abuts against the first groove. The electromagnet 5 and the iron connecting frames 16 on the left and right ends of the upper pressure plate 1 form a controllable disassembly structure. When the electromagnet 5 is not energized, there is no connection between the electromagnet 5 and the connecting frame 16, that is, the upper pressure plate 1 and the test block mold 4 can be disassembled. In the test block molding stage, it is necessary to ensure the stability of the connection between the various structures. Therefore, the electromagnet 5 is energized so that the electromagnet 5 generates magnetic attraction to the connecting frame 16, so that the upper pressure plate 1 and the test block mold 4 are in a fixed state to avoid shaking.

[0026] Furthermore, circular bumps 19 are installed at the bottom of the left and right ends of the support plate 2. Second grooves are provided on the upper surfaces of the first fixing block 14 and the second fixing block 15. The second grooves are arc-shaped, and the circular bumps 19 abut against the second grooves. After the circular bumps 19 and the second grooves are provided, when a test block is placed on the support plate 2, the overall weight of the support plate 2 is relatively large, so the support plate 2 is not easy to shake during the lifting process. However, the support plate 2 is not fixedly connected to the first fixing block 14 and the second fixing block 15, which facilitates the removal of the support plate 2.

[0027] Furthermore, a pad 17 is provided on the base 20 and is located below the support plate 2. The pad 17 acts as a buffer for the descending support plate 2 to prevent the support plate 2 carrying the test block from damaging the base 20 during the descending process.

[0028] The words "connection" and "fixation" appearing in the description of the present invention may refer to fixed connection, processing and forming, welding, or mechanical connection. The specific meanings of the above terms in the present invention shall be understood according to the specific circumstances.

[0029] In the description of the present invention, the terms "center", "upper", "lower", "horizontal", "inner", "outer", etc., which indicate the orientation or position relationship, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents.
