TECHNICAL FIELD

[0001] The utility model relates to concrete technical field especially relates to a gasification slag replaces mechanism sand to the experiment equipment of concrete strength influence. BACKGROUND

[0002] Gasification slag is the waste slag produced in the production process of gasification furnace, and the water content of gasification slag is between 15% and 30%, the color is black, can be recycled, mainly sold to cement plant, replaces mechanism sand, is used for making concrete. But the concrete made by using gasification slag needs to test the performance of the sample made before actual use, so as to be able to fully grasp the quality of concrete. However, when the flexural strength of concrete is detected, the detection data cannot be controlled in time, and the existing detection device can only detect single item of concrete, so it is inconvenient to use, therefore we propose a gasification slag replaces mechanism sand to the experiment equipment of concrete strength influence. SUMMARY

[0003] The utility model discloses a kind of gasification slag replaces mechanism sand to the experiment equipment of concrete strength influence, to solve the problem proposed above.

[0004] To achieve the above object, the utility model adopts the following technical scheme:

[0006] Clamping mechanism, clamping mechanism is installed at the top of support seat, clamping mechanism is matched with support seat, for clamping positioning to concrete board, one side of clamping mechanism is installed at the top of bottom plate;

[0007] Experimental mechanism, experimental mechanism is installed at the top of bottom plate, experimental mechanism is used to test concrete board;

[0008] Power mechanism, power mechanism is installed at the top of bottom plate, power mechanism is connected with one side of experimental mechanism, power mechanism is used to drive experimental mechanism to move.

[0009] In a possible design, the clamping mechanism comprises two first limiting rods symmetrically and fixedly installed on the top of the support base, a same first limiting plate slidably sleeved on the two first limiting rods, an L-shaped pressing plate fixedly installed on one side of the first limiting plate, a plurality of anti-skid strips fixedly installed on the top inner wall of the L-shaped pressing plate and the top of the support base at equal intervals, the plurality of anti-skid strips being in contact with the concrete plate, an adjusting assembly installed on the other side of the first limiting plate, and the adjusting assembly connected with the top of the bottom plate.

[0010] In a possible design, the adjusting assembly comprises a threaded plate fixedly installed on the other side of the first limiting plate, a screw threadedly connected through the threaded plate, a bottom end of the screw rotatably connected with the top of the bottom plate, and a hand wheel fixedly installed on a top end of the screw.

[0011] In a possible design, the experimental mechanism comprises two second limiting rods symmetrically and fixedly installed on the top of the bottom plate, a same second limiting plate slidably sleeved on the two second limiting rods, a U-shaped transmission frame fixedly installed on one side of the second limiting plate, the concrete plate extending into the U-shaped transmission frame, a plurality of pressing rods fixedly installed on the top inner wall of the U-shaped transmission frame at equal intervals, the plurality of pressing rods being used for puncture experiments on the concrete plate, limiting rings fixedly installed on the top and the bottom of the second limiting plate, a same U-shaped plate slidably connected through the two limiting rings, one side of the U-shaped plate connected with the power mechanism, and a same pressure test assembly installed on the top of the U-shaped plate and the top of the upper limiting ring.

[0012] In a possible design, the pressure test assembly comprises a fixed plate fixedly installed on the top of the upper limiting ring and a test pressing plate fixedly installed on one side of the top of the U-shaped plate, a display screen and a pressure sensor fixedly installed on the two sides of the fixed plate respectively, the pressure sensor corresponding in position to the test pressing plate, and the pressure sensor electrically connected with the display screen.

[0013] In a possible design, the power mechanism comprises two support plates fixedly installed on the other side of the top of the bottom plate, a same transmission bar ring rotatably connected on the two support plates, one side of the transmission bar ring rotatably connected with one side of the U-shaped plate, an electric push rod fixedly installed on the top of the bottom plate between the two support plates, a transmission assembly installed on an output shaft of the electric push rod, the transmission assembly installed on the top of the bottom plate, and the transmission assembly penetrating through and in transmission connection with the transmission bar ring.

[0014] In one possible design, the transmission assembly includes a transmission plate fixedly mounted on the output shaft of an electric push rod. A first stop rod is fixedly mounted through the transmission plate. Two swing rods are rotatably connected to the top of the base plate. The swing rods have transmission holes. The first stop rod passes through the two transmission holes and engages with the two transmission holes respectively. The same second stop rod is fixedly mounted on the top of the side of the two swing rods that are close to each other. The second stop rod passes through the transmission bar ring and engages with the transmission bar ring.

[0015] In this application, after the concrete slab is placed on the support base, the handwheel is turned to drive the screw to rotate. At this time, under the threaded transmission action with the threaded plate, the first limiting plate can be driven to move longitudinally, which can drive the L-shaped pressure plate to move downward so as to clamp and position the concrete slab. Then, the electric push rod is activated to drive the transmission plate to move away from the electric push rod. At this time, under the pushing action of the first stop rod, the two swing rods can be driven to rotate upward, which can drive the second stop rod to move upward in an arc. This can drive the transmission bar ring to rotate upward, which can drive the U-shaped plate to move upward in an arc. Under the sliding cooperation between the U-shaped plate and the two limiting rings, the second limiting plate can be driven to move upward, which can drive the U-shaped transmission frame to move upward, so that the U-shaped transmission frame contacts the bottom of the concrete slab. As the U-shaped transmission frame continues to move upward, a pushing force can be applied to the concrete slab, thereby testing the flexural strength of the concrete slab.

[0016] When the electric push rod is activated, it drives the transmission plate to move closer to the electric push rod. At this time, it can drive the overall structure to reverse the transmission, which can drive the transmission bar ring to rotate downward, causing the U-shaped transmission frame to move downward. At this time, multiple pressure rods can be used to press the concrete slab and conduct a puncture test on the concrete slab, thereby detecting the tightness of the concrete slab.

[0017] When the transmission ring rotates up or down, it can drive the U-shaped plate to move away from the U-shaped transmission frame. At this time, it can drive the test plate to move, so that the test plate comes into contact with the pressure sensor. The test plate applies pressure to the pressure sensor. As the force received by the U-shaped plate increases, the pressure on the pressure sensor also increases until the concrete slab is punctured or broken. The flexural strength and density of the concrete slab can be detected, and the detected data can be transmitted to the display screen to display the pressure value.

[0018] Beneficial effects:

[0019] In this utility model, the experimental equipment for measuring the effect of gasified slag replacing manufactured sand on concrete strength can, through a clamping mechanism, allow the concrete slab to be placed on the support base. At this time, the adjustment component can be operated to drive the first limiting plate to move downward, which in turn drives the L-shaped pressure plate to move downward. The L-shaped pressure plate and the support base can be used to clamp and position the concrete slab.

[0020] In this invention, the experimental device for measuring the effect of gasified slag replacing manufactured sand on concrete strength, through the experimental mechanism, allows the U-shaped plate to move after being driven by the power mechanism. At this time, under the sliding cooperation with the two limiting rings, the second limiting plate can be driven to move longitudinally, thereby driving the U-shaped transmission frame to move longitudinally. When the U-shaped transmission frame moves upward, it can provide an upward thrust to the concrete slab, thereby testing the flexural strength of the concrete slab. When the U-shaped transmission frame moves downward, multiple pressure rods can be used to prick the concrete slab, thereby detecting the compactness of the concrete slab.

[0021] In this utility model, the experimental equipment for measuring the effect of gasified slag replacing manufactured sand on concrete strength can be driven by a power mechanism to move the transmission component by starting an electric push rod. At this time, the transmission bar ring can be driven to rotate up or down, thereby driving the U-shaped plate to move in an arc shape. In this way, under the sliding cooperation with the two limiting rings, the second limiting plate can be driven to move longitudinally, so that the U-shaped transmission frame can move longitudinally.

[0022] This invention uses an electric push rod to drive a U-shaped transmission frame to move longitudinally, thereby enabling the testing of the compactness and flexural strength of concrete slabs. During the testing process, the pressure value on the concrete slab can also be detected, thus allowing for accurate testing of concrete slabs made from gasified slag. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Example 1

[0032] Reference Figures 1-6 An experimental device includes an experimental platform consisting of a base plate 1. A support base 2 is fixedly installed on one side of the top of the base plate 1 by means of welding or bolt connection. The support base 2 is used to support a concrete slab 7 to be tested.

[0033] A clamping mechanism is installed to fix the concrete slab 7. The clamping mechanism includes two first limiting rods 3 symmetrically fixedly installed on the top of the support base 2. The same first limiting plate 4 is slidably sleeved on the two first limiting rods 3. An L-shaped pressure plate 5 is fixedly installed on one side of the first limiting plate 4. Multiple anti-slip strips 6 are welded or pasted at equal intervals on the top inner wall of the L-shaped pressure plate 5 and the top of the support base 2. The multiple anti-slip strips 6 ensure that they can make close contact with and fix the concrete slab 7 during the clamping process. In order to adjust the position of the first limiting plate 4, an adjustment component is designed. This component includes a fixing... A threaded plate 8 is installed on the other side of the first limiting plate 4. A screw 9 is threaded through the threaded plate 8. The bottom end of the screw 9 is connected to the top of the base plate 1 through a bearing to ensure that the screw 9 can rotate freely without moving its position. A handwheel 10 is fixedly installed at the top of the screw 9 for easy manual rotation. After the concrete slab 7 is placed on the support base 2, the screw 9 is rotated by rotating the handwheel 10. Using the thread transmission principle, the first limiting plate 4 moves downward along the first limiting rod 3, thereby driving the L-shaped pressure plate 5 downward to achieve clamping and positioning of the concrete slab 7.

[0034] The experimental mechanism is installed to conduct concrete strength testing. The experimental mechanism includes two second limiting rods 11 symmetrically fixedly installed on the top of the base plate 1. The same second limiting plate 12 is slidably sleeved on the two second limiting rods 11. A U-shaped transmission frame 13 is fixedly installed on one side of the second limiting plate 12. One side of the concrete slab 7 extends into the U-shaped transmission frame 13. Multiple pressure rods 131 are welded at equal intervals on the top inner wall of the U-shaped transmission frame 13 for puncture testing of the concrete slab 7. Limiting rings 14 are welded to the top and bottom of the second limiting plate 12. The same U-shaped plate 15 is slidably connected through the two limiting rings 14. One side of the U-shaped plate 15 is connected to the power mechanism.

[0035] A power mechanism, such as a cylinder or motor-driven push rod, is installed on the top of the base plate 1 and connected to one side of the U-shaped plate 15. When the power mechanism is started, the extension and retraction of the push rod or cylinder drives the U-shaped plate 15 and the entire experimental mechanism to move, completing the strength test of the concrete slab 7. During the test, the pressure sensor 19 measures the pressure applied to the concrete slab 7 by the test plate 18 in real time and transmits the data to the display screen 21 for display, thereby intuitively reflecting the flexural strength and density of the concrete slab 7.

[0036] In the power mechanism section, firstly, two support plates 17 are fixedly installed on the other side of the top of the base plate 1 by welding or bolting. The two support plates 17 should be parallel and stable to support the subsequent transmission structure. Then, a transmission ring 16 is installed between the two support plates 17. The two ends of the transmission ring 16 are rotatably connected to the support plates 17 by bearings or similar devices to ensure that it can rotate freely. One side of the transmission ring 16 is connected to one side of the U-shaped plate 15 by a hinge or similar rotating connector. In this way, the rotation of the transmission ring 16 can drive the U-shaped plate 15 to perform arc-shaped movement.

[0037] At the top of the base plate 1, between the two support plates 17, an electric push rod 22 is fixedly installed. The selection of the electric push rod 22 should be determined according to the driving force and stroke required for the experiment. A transmission plate 23 is installed on the output shaft of the electric push rod 22. The transmission plate 23 is firmly fixed to the output shaft by bolts or other fastening methods.

[0038] A first stop bar 25 is installed through and fixed on the transmission plate 23. At the same time, two swing bars 24 are rotatably connected to the top of the base plate 1. The two swing bars 24 should be located on both sides of the first stop bar 25, and each swing bar 24 has a transmission hole. The first stop bar 25 passes through the two transmission holes and forms a transmission engagement with the transmission holes. That is, when the first stop bar 25 moves, it can push the swing bar 24 to rotate around its rotation point.

[0039] A second stop 26 is fixedly installed on the top of the two swing rods 24 on the side that are close to each other. The second stop 26 passes through a preset hole in the transmission bar ring 16 and forms a transmission engagement with the transmission bar ring 16. In this way, when the swing rods 24 rotate, the second stop 26 will swing in an arc shape, thereby driving the transmission bar ring 16 to rotate.

[0040] During the experiment, the electric push rod 22 is activated. The output shaft of the electric push rod 22 pushes the transmission plate 23 to move, which in turn drives the first stop rod 25 to move laterally. The movement of the first stop rod 25 drives the two swing rods 24 to rotate upward or downward. The rotation of the swing rods 24 drives the second stop rod 26 to swing in an arc. Since the second stop rod 26 is in transmission cooperation with the transmission bar ring 16, the transmission bar ring 16 will also rotate. The rotation of the transmission bar ring 16 is connected to the rotation of the U-shaped plate 15, which drives the U-shaped plate 15 to move in an arc. The arc movement of the U-shaped plate 15, in sliding cooperation with the two limit rings 14, drives the second limit plate 12 to move longitudinally, thereby driving the U-shaped transmission frame 13 to move longitudinally, realizing the upward and downward pushing or puncture test on the concrete slab 7.

[0041] This application can be used in the field of concrete technology, or in other fields applicable to this application.

[0042] Example 2

[0043] refer to Figure 3 and Figure 4 Based on the first embodiment, an improved experimental device for measuring the effect of gasified slag replacing manufactured sand on concrete strength is applied to the field of concrete technology. To measure pressure, a pressure testing assembly is installed, including a fixed plate 20 fixedly mounted on the top of the upper limiting ring 14, and a test pressure plate 18 fixedly mounted on one side of the top of the U-shaped plate 15. A display screen 21 and a pressure sensor 19 are fixedly mounted on both sides of the fixed plate 20, respectively. The pressure sensor 19 corresponds to the position of the test pressure plate 18 and is connected to the display screen 21 via a circuit. When the U-shaped plate 15 is driven by a power mechanism, it slides along the two limiting rings 14, thereby driving the second limiting plate 12 and the U-shaped transmission frame 13 to move longitudinally. When the U-shaped transmission frame 13 moves upward, it provides an upward thrust to the concrete slab 7 to test its flexural strength; when it moves downward, the pressure rod 131 is used to prick the concrete slab 7 to detect its compactness.

[0044] However, as is well known to those skilled in the art, the working principles and wiring methods of the pressure sensor 19, display screen 21 and electric actuator 22 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
