Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, and particularly relates to a surface grinding device for concrete blocks used in impermeability experiments. Background Art

[0002] When the existing concrete blocks for impermeability experiments are used, they need to be ground into the shapes required for the experiments.

[0003] Currently, the existing grinding device (such as patent number: CN213411500U) discloses a surface grinding device for concrete test blocks. When grinding a workpiece, the turntable is adjusted to be relatively fixed with the base to facilitate the grinding operation. When it is necessary to adjust the orientation of the test block, the turntable can be rotated relative to the base. The turntable drives the test block to rotate so that the surface to be ground can be rotated to the position where the grinding disc is located. There is no need to disassemble the limit of the test block, nor to move or adjust the test block separately, which reduces the operation difficulty, improves the test efficiency, and also avoids the test error caused by the movement of the test block.

[0004] However, in the process of implementing the above technical solution, it is found that there are at least the following technical problems: when the existing surface grinding device for concrete blocks is used, a grinding disc is used to grind the surface of the concrete block. However, since the moving mechanism and the rotating mechanism cannot operate in cooperation at the same time, when grinding the concrete block, it is difficult to grind the corners and the center evenly, and even manual operation of displacement is required for multiple grindings. Summary of the Utility Model

[0007] (II) Technical Solutions

[0008] To achieve the above object, the utility model is realized through the following technical solutions:

[0009] A surface grinding device for concrete blocks used in impermeability experiments includes a grinding table. A support frame is fixedly installed at the upper end of the grinding table. A first motor is arranged at the lower end of the horizontal section of the support frame. The end of the output shaft of the first motor is fixedly installed with a grinding disc, and the grinding disc is used to grind the concrete for impermeability experiments;

[0010] Among them, a sliding table is installed inside the grinding table. A third motor is fixedly installed inside the sliding table. A support plate is fixedly installed at the end of the output shaft of the third motor. Second hydraulic cylinders are arranged on both the left and right sides of the support plate, and the two second hydraulic cylinders are used to fix the concrete for the impermeability test during grinding.

[0011] Preferably: A first hydraulic cylinder is fixedly installed at the lower end of the horizontal section of the support frame;

[0012] Among them, a connecting frame is fixedly installed at the end of the output shaft of the first hydraulic cylinder. The upper end of the first motor is embedded inside the connecting frame, and the first motor is fixedly connected to the connecting frame;

[0013] Among them, the first motor and the connecting frame are at an oblique angle. A second motor is fixedly installed on the inner side wall of the grinding table;

[0014] Among them, a threaded rod is fixedly installed at the end of the output shaft of the second motor.

[0015] Preferably: The end of the threaded rod is rotationally connected to the inner wall of the grinding table;

[0017] Among them, rubber chucks are fixedly installed at the ends of the output shafts of the two second hydraulic cylinders, and the two rubber chucks are used to clamp the concrete for the impermeability test during grinding.

[0018] (III) Beneficial effects

[0019] First, the horizontal movement of the sliding table will drive the horizontal movement of the third motor. The horizontal movement of the third motor will drive the horizontal movement of the support plate. The horizontal movement of the support plate will drive the movement of the concrete for the impermeability test. At this time, the concrete for the impermeability test will rotate during the movement and be ground by the grinding disc at the same time. By adopting this way of coexisting movement and rotation, the uniformity of grinding the concrete for the impermeability test can be greatly improved.

[0020] Second, the downward movement of the connecting frame will drive the downward movement of the first motor. The downward movement of the first motor will drive the downward movement of the grinding disc. The grinding disc moves downward to contact the concrete for the impermeability test and grind it. Since the grinding disc is at an oblique angle, when the grinding disc grinds the concrete for the impermeability test, the smoothness during grinding can be effectively improved.

[0027] In the embodiment of the present application, by providing a surface grinding device for concrete blocks used in impermeability experiments, it effectively solves the problem that when the existing concrete block surface grinding device is in use, a grinding disc is used to grind the surface of the concrete block. However, due to the inability of the moving mechanism and the rotating mechanism to operate in coordination at the same time, when grinding the concrete block, it is difficult to grind the edges and corners and the center evenly. Even manual displacement is required for multiple grindings. The horizontal movement of the sliding table 2 will drive the third motor 21 to move horizontally. The horizontal movement of the third motor 21 will drive the support plate 22 to move horizontally. The horizontal movement of the support plate 22 will drive the concrete block for impermeability experiments to move. At this time, the concrete block for impermeability experiments will rotate during the movement and be ground by the grinding disc 15 at the same time. By adopting this method of coexisting movement and rotation, the grinding uniformity of the concrete block for impermeability experiments can be greatly improved.

[0028] Embodiment

[0029] Such as Figure 1 、 Figure 2 、 Figure 3 And Figure 4As shown in the figure, the technical solution in the embodiment of the present application effectively solves the technical problem that when the existing concrete block surface grinding device is in use, a grinding disc is used to grind the surface of the concrete block. However, since the moving mechanism and the rotating mechanism cannot cooperate and operate simultaneously, when grinding the concrete block, it is difficult to grind the edges and corners and the center evenly, and even manual operation of displacement is required for multiple grindings. The general idea is as follows:

[0030] In view of the problems existing in the prior art, the utility model provides a surface grinding device for concrete blocks used in impermeability experiments, including a grinding table 1. A support frame 11 is fixedly installed at the upper end of the grinding table 1. A first motor 14 is arranged at the lower end of the horizontal section of the support frame 11. The end of the output shaft of the first motor 14 is fixedly installed with a grinding disc 15, and the grinding disc 15 is used to grind the concrete for impermeability experiments. Among them, a sliding table 2 is installed inside the grinding table 1. A third motor 21 is fixedly installed inside the sliding table 2. The end of the output shaft of the third motor 21 is fixedly installed with a support plate 22. Second hydraulic cylinders 24 are arranged on both the left and right sides of the support plate 22, and the two second hydraulic cylinders 24 are used to fix the concrete for impermeability experiments. The horizontal movement of the sliding table 2 will drive the third motor 21 to move horizontally. The horizontal movement of the third motor 21 will drive the support plate 22 to move horizontally. The horizontal movement of the support plate 22 will drive the concrete for impermeability experiments to move. At this time, the concrete for impermeability experiments will rotate during the movement and be ground by the grinding disc 15 at the same time. By adopting this way of coexisting movement and rotation, the evenness of grinding the concrete for impermeability experiments can be greatly improved.

[0031] A first hydraulic cylinder 12 is fixedly installed at the lower end of the horizontal section of the support frame 11. Among them, the end of the output shaft of the first hydraulic cylinder 12 is fixedly installed with a connecting frame 13. The upper end of the first motor 14 is embedded in the inside of the connecting frame 13, and the first motor 14 is fixedly connected with the connecting frame 13. Among them, there is an oblique angle between the first motor 14 and the connecting frame 13. A second motor 16 is fixedly installed on the inner side wall of the grinding table 1. Among them, the end of the output shaft of the second motor 16 is fixedly installed with a threaded rod 17. The operation of the first hydraulic cylinder 12 drives the connecting frame 13 to move downward. The downward movement of the connecting frame 13 will drive the first motor 14 to move downward. The downward movement of the first motor 14 will drive the grinding disc 15 to move downward. The grinding disc 15 moves downward to contact the concrete for impermeability experiments and grind it.

[0032] The end of the threaded rod 17 is rotatably connected to the inner wall of the grinding table 1; among them, the threaded rod 17 passes through the inside of the sliding table 2 through threads. Two connecting plates 23 are fixedly installed at the upper end of the support plate 22, and each second hydraulic cylinder 24 is fixedly connected to the connecting plate 23; among them, rubber chucks 25 are fixedly installed at the ends of the output shafts of the two second hydraulic cylinders 24, and the two rubber chucks 25 are used to clamp the concrete for the impermeability test. The two rubber chucks 25 move closer to each other to push the concrete for the impermeability test to the center of the support plate 22 and clamp the concrete for the impermeability test. At this time, the second motor 16 operates to drive the threaded rod 17 to rotate through the output shaft. The rotation of the threaded rod 17 drives the sliding table 2 to move horizontally, and the horizontal movement of the sliding table 2 will drive the third motor 21 to move horizontally.

[0033] Working principle:

[0034] First step, the user places the concrete for the impermeability test to be ground on the support plate 22, starts the two second hydraulic cylinders 24, and the two second hydraulic cylinders 24 operate to drive the two rubber chucks 25 to move closer to each other through the output shafts. The two rubber chucks 25 move closer to each other to push the concrete for the impermeability test to the center of the support plate 22 and clamp the concrete for the impermeability test. At this time, the second motor 16 operates to drive the threaded rod 17 to rotate through the output shaft. The rotation of the threaded rod 17 drives the sliding table 2 to move horizontally, and the horizontal movement of the sliding table 2 will drive the third motor 21 to move horizontally. The horizontal movement of the third motor 21 will drive the support plate 22 to move horizontally, and the horizontal movement of the support plate 22 will drive the concrete for the impermeability test to move. At this time, the concrete for the impermeability test will rotate during the movement and be ground by the grinding disc 15 at the same time. By adopting this way of coexisting movement and rotation, the uniformity of grinding the concrete for the impermeability test can be greatly improved.

[0035] Second step, during grinding, the first hydraulic cylinder 12 operates to drive the connecting frame 13 to move downward. The downward movement of the connecting frame 13 will drive the first motor 14 to move downward. The downward movement of the first motor 14 will drive the grinding disc 15 to move downward. The grinding disc 15 moves downward to contact the concrete for the impermeability test and grind it. Since the grinding disc 15 is at an oblique angle, when the grinding disc 15 grinds the concrete for the impermeability test, the smoothness during grinding can be effectively improved.

[0036] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
