Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the utility model.
[0025] The following gives specific embodiments.
[0026] Please refer to Figures 1-4, the present utility model provides a device for testing the compressive resistance of concrete test blocks, including an operating table 1, characterized in that: a bidirectional screw 2 is rotatably connected inside the operating table 1; both ends of the center position of the bidirectional screw 2 are threadedly connected with columns 3; the top ends of the columns 3 are fixedly connected with fixed circular plates 4; both ends of the two fixed circular plates 4 facing each other are fixedly connected with detection plates 5; the end of the fixed circular plate 4 away from the detection plate 5 is fixedly connected with a support frame 6; both ends of the bidirectional screw 2 are threadedly connected with threaded sleeves 7; the circumferential side of the threaded sleeve 7 is fixedly connected with a support base 8; the top end of the support base 8 is fixedly connected with the support frame 6;
[0027] A placement component; it is arranged at the position of the bottom end of the detection plate 5 at one end of the bidirectional screw 2; the placement component is used to cooperate with the detection plate 5. During operation, when the concrete test block to be subjected to lateral bearing capacity test is placed on the placement component, by driving the two detection plates 5 to move relatively, it is convenient to test the lateral bearing capacity of the concrete, improve the all-round detection effect of the concrete test block, and further improve the comprehensiveness of the detection data of the concrete test block. And through the structural cooperation design of the support frame 6, when the detection plate 5 applies detection pressure to the concrete, it is convenient to support the column 3 and the detection plate 5 bearing the reverse pressure through the support frame 6, improving the stability of the device during use.
[0028] Furthermore, as Figure 2 shown, a first transmission column 9 is rotatably connected inside one end of the operating table 1; the end of the first transmission column 9 away from the bidirectional screw 2 is fixedly connected with a first bevel gear 10; a second transmission column 11 is rotatably connected inside the operating table 1 at a position corresponding to the first transmission column 9; the bottom end of the second transmission column 11 is fixedly connected with a second bevel gear 12; the second bevel gear 12 is meshed and connected with the first bevel gear 10; a servo motor 13 is fixedly connected at the top end of the operating table 1 at a position corresponding to the second transmission column 11; the bottom end of the servo motor 13 is fixedly connected with the second transmission column 11. During operation, when it is necessary to start the bidirectional screw 2, by starting the servo motor 13, the output end of the servo motor 13 drives the second transmission column 11 and the second bevel gear 12 to rotate, and then the second bevel gear 12 drives the first transmission column 9 to rotate through the first bevel gear 10, thus conveniently driving the first transmission column 9 and the bidirectional screw 2 to rotate through the first bevel gear 10.
[0029] Furthermore, as Figure 4As shown, the placement component includes a placement base 14, a fixed column 15, a fixed sleeve 16, and a placement rack 17; the bottom end of the detection plate 5 at one end of the bidirectional screw 2 is fixedly connected to the placement base 14; the inner side of the placement base 14 is rotatably connected to the fixed column 15; the circumferential side of the fixed column 15 is fixedly connected to the fixed sleeve 16; the circumferential side of the fixed sleeve 16 is fixedly connected to the placement rack 17. During operation, the connection between the fixed column 15 and the placement base 14 facilitates adjusting the operation angle of the placement component, thereby facilitating the contact between the two detection plates 5 and the concrete test block and applying pressure to it. By adjusting the fixed column 15, the placement component is disconnected from the concrete test block.
[0030] Further, as Figure 4 shown, the placement component further includes a placement sleeve 18 and a telescopic placement column 19; the end of the placement rack 17 away from the placement base 14 is fixedly connected to the placement sleeve 18; the inner side of the placement sleeve 18 is slidably connected to the telescopic placement column 19. During operation, the placement sleeve 18 and the telescopic placement column 19 facilitate the placement of the concrete test block, and the telescopic placement column 19 that can be telescoped within the placement sleeve 18 facilitates adjusting its placement space, thereby facilitating the use of concrete test blocks of different sizes.
[0031] Further, as Figure 4 shown, the placement component further includes a clamping column 20 and a clamping round seat 21; one side of the placement base 14 is rotatably connected to the clamping column 20; the end of the clamping column 20 located inside the placement base 14 is fixedly connected to the fixed column 15; the end of the clamping column 20 away from the placement base 14 is fixedly connected to the clamping round seat 21. During operation, when it is necessary to adjust the angle of the fixed column 15, it is convenient to rotate it through the clamping column 20 and the clamping round seat 21.
[0032] Further, as Figure 3 shown, the placement component further includes a clamping strip 22 and a clamping rod 23; one side of the detection plate 5 corresponding to the clamping column 20 is fixedly connected to the clamping strip 22; the inner side of the clamping strip 22 is slidably connected to the clamping rod 23; the bottom end of the clamping rod 23 is detachably connected to the clamping round seat 21. During operation, when it is necessary to limit the fixed column 15 to facilitate adjusting its angle, by pulling up the clamping rod 23, the connection between the clamping rod 23 and the clamping round seat 21 is released, making it convenient to adjust the fixed column 15.
[0033] Further, as Figure 3 shown, the placement sleeve 18 and the telescopic placement column 19 are made of stainless steel. During operation, due to the material of the placement sleeve 18 and the telescopic placement column 19, concrete test blocks with a relatively high weight can be placed on them.
[0034] Working principle: After placing the concrete test block that needs to be subjected to lateral bearing capacity detection on the placement component, by driving the two detection plates 5 to move relative to each other, it is convenient to detect the lateral bearing capacity of the concrete, improve the all-round detection effect of the concrete test block, and further improve the comprehensiveness of the detection data of the concrete test block. And through the structural cooperation design of the support frame 6, when the detection plate 5 applies detection pressure to the concrete, it is convenient to support the column 3 and the detection plate 5 that bear the reverse pressure through the support frame 6, improving the stability of the device during use. When it is necessary to start the bidirectional screw 2, by starting the servo motor 13, the output end of the servo motor 13 drives the second transmission column 11 and the second bevel gear 12 to rotate. Then, the second bevel gear 12 drives the first transmission column 9 to rotate through the first bevel gear 10. Thus, it is convenient to drive the first transmission column 9 and the bidirectional screw 2 to rotate through the first bevel gear 10. The connection between the fixed column 15 and the placement seat 14 facilitates adjusting the operation angle of the placement component. Thus, when the two detection plates 5 are in contact with the concrete test block and apply pressure to it, by adjusting the fixed column 15, the placement component is disconnected from the concrete test block. The placement sleeve 18 and the telescopic placement column 19 facilitate the placement of the concrete test block. And through the telescopic placement column 19 that can be telescoped in the placement sleeve 18, it is convenient to adjust its placement space, thus facilitating the use of concrete test blocks of different sizes. When it is necessary to adjust the angle of the fixed column 15, it is convenient to rotate it through the clamping column 20 and the clamping circular seat 21. When it is necessary to limit the fixed column 15 to facilitate adjusting its angle, by pulling up the clamping rod 23, the connection between the clamping rod 23 and the clamping circular seat 21 is released, making it convenient to adjust the fixed column 15. Due to the materials of the placement sleeve 18 and the telescopic placement column 19, concrete test blocks with higher weights can be placed on them.
