[0004] The prior art mainly limits and fixes the concrete test piece through two symmetrically arranged clamping blocks. When the test piece is extruded by the pressing block, the huge pressure of the hydraulic rod will cause the test piece to break, and some debris will splash around. The high-speed moving stones or concrete fragments have certain safety hazards. Therefore, it is necessary to block and collect the debris when the test piece is extruded and broken.

[0005] Therefore, we propose a device for detecting the compressive strength of concrete. Content of the Utility Model

[0018] Beneficial effects

[0019] The present utility model provides a device for detecting the compressive strength of concrete. It has the following beneficial effects:

[0020] 1. This concrete compressive strength testing device, through two symmetrically arranged protective bodies, jointly shields the protective test bench and forms a protective barrier around the test bench. When the test block is crushed by pressure, the protective body and the plug plate can limit the splashing of the fragments, thereby improving the protection effect and safety. At the same time, the protective body with an inclined bottom can collect crushed stones, which is convenient for centralized cleaning later. When it is necessary to pour out the debris in a centralized manner, the protective body can be pushed to move and flip along the guide rod, and then the concrete fragments collected in the protective body can be poured out, which is convenient for discharge.

[0021] 2. This concrete compressive strength testing device is provided with a handle fixed on the wall of the plug plate by setting convex ribs and slots. The plug plate is pulled to move up, and the plug plate drives the convex ribs to slide in the slots, so that the bottom of the plug plate is separated from the protective body. With the flippable protective body, the protective body can be kept in an inclined posture to pour out the collected concrete fragments. When sealing the front of the protective body, it only needs to push the protective body down. It is simple to operate and easy to use.

[0022] 3. In this concrete compressive strength testing device, when the protective body slides, the protective body drives the sliding rod to slide in the sliding groove of the guide rod. When the front of the protective body slides to the front of the base and is in a suspended state, the concrete in the protective body and the gravity of the protective body itself will cause the protective body to flip toward the limit plate. The bottom of the protective body flips to fit the top surface of the limit plate to form an inclined state for slag discharge. The eccentric effect of the connection position between the protective body and the sliding rod can be used to promote slag discharge, further optimize the slag discharge method, and make it more labor-saving and convenient.

[0029] A concrete compressive strength testing device, such asFigure 1 and Figure 2 as shown in the figure, including:

[0030] A base 10, a frame structure for support;

[0031] A ram 11, arranged above the base 10 for extruding concrete, and the ram 11 is pushed by an oil cylinder;

[0032] A test bench 12, arranged above the base 10, and a pressure sensor is arranged between the test bench 12 and the ram 11. Of course, a controller is also installed on one side of the base 10 to control the oil cylinder and receive the sensor signal. The controller is connected to a display screen, and the signal of the sensor is transmitted to the display screen through the controller. The oil cylinder is fixedly installed on the top of the base 10, and the ram is fixedly installed at the end of the output shaft of the oil cylinder. The ram 11 is pushed by the oil cylinder to move downwards close to the test bench 12, and then the pressure exerted by the ram 11 on the test bench 12 is displayed, that is, the pressure received by the concrete test block, so as to realize the compressive strength test of the test block. The pressure sensor is a known prior art, and the specific control method will not be elaborated here;

[0033] As Figure 2 、 Figure 3 and Figure 4 shown in the figure, a protection component, arranged on the top of the base 10 for shielding the ram 11 and the test bench 12. The protection component includes a protection main body 20, a plug board 21 and a guide rod 30. The guide rod 30 is fixedly installed on the top surface of the base 10. The protection main body 20 can slide and flip along the guide rod 30. The plug board 21 is inserted into the protection main body 20. The bottom of the protection main body 20 is inclined towards the plug board 21. The plug board 21 can collect the crushed concrete blocks on the test bench 12 and flip and discharge the slag away from the base 10. The protection main body 20 forms a box structure with openings at the top and front and back. The plug board 21 is adapted to the front opening of the protection main body 20. The plug board 21 shields and seals the front opening of the protection main body 20. Two protection main bodies 20 and plug boards 21 are symmetrically arranged on the guide rod 30. The two protection main bodies 20 and plug boards 21 together form a box with an opening at the top to collect concrete blocks. In this solution, the two symmetrically arranged protection main bodies 20 jointly shield and protect the test bench 12 and form a protection barrier around the test bench 12. When the test block is crushed under pressure, the protection main body 20 and the plug board 21 can limit the splashing of the broken blocks, improve the protection effect and safety. At the same time, the protection main body 20 with an inclined bottom can collect the crushed stones, which is convenient for later centralized cleaning. When it is necessary to pour out the debris centrally, the protection main body 20 can be pushed to move and flip along the guide rod 30, and then the concrete broken blocks collected in the protection main body 20 can be poured out, which is for the purpose of facilitating discharging.

[0034] As Figure 3 and Figure 4As shown, the protection component further includes a rib 22 and a slot 23. A slot 23 is formed on the wall surface of the protection main body 20. The rib 22 is fixedly arranged on one side of the insertion plate 21. The rib 22 can be inserted into the slot 23. The slot 23 is formed on the top surface of the protection main body 20 and extends towards the bottom. The depth of the slot 23 is less than the height of the protection main body 20. The rib 22 forms a rectangular rod structure. The rib 22 and the insertion plate 21 are integrally formed. The slot 23 is adapted to the rib 22. The rib 22 and the slot 23 are of the same height. As a supplement to the above solution, by providing the rib 22 and the slot 23, a handle is fixedly arranged on the wall surface of the insertion plate 21. Pulling the handle drives the insertion plate 21 to move upward. The insertion plate 21 drives the rib 22 to slide in the slot 23. Then the bottom of the insertion plate 21 is separated from the protection main body 20. Cooperating with the rotatable protection main body 20, the protection main body 20 can be kept in an inclined posture to pour out the collected concrete debris. When sealing the front of the protection main body 20, only need to push the protection main body 20 downward. The operation is simple and easy to use.

[0035] As Figure 4 and Figure 5 As shown, the protection component further includes a limiting plate 31 and a sliding rod 32. The sliding rod 32 is slidably connected to the guide rod 30. The protection main body 20 is hinged to the sliding rod 32. The limiting plate 31 is fixedly connected to the guide rod 30. The protection main body 20 can rotate around the sliding rod 32 and abut against the top surface of the limiting plate 31. A chute is formed on the top surface of the guide rod 30. The sliding rod 32 is adapted to the chute and is slidably connected to the chute. The hinged position of the protection main body 20 and the sliding rod 32 is close to the limiting plate 31. The limiting plate 31 is fixedly installed at the end of the guide rod 30 away from the base 10. In this solution, when the protection main body 20 slides, the protection main body 20 drives the sliding rod 32 to slide in the chute of the guide rod 30. When the front of the protection main body 20 slides to the front of the base 10 and is in a suspended state, the concrete in the protection main body 20 and the gravity of the protection main body 20 itself will cause the protection main body 20 to rotate towards the limiting plate 31. The bottom of the protection main body 20 rotates to fit the top surface of the limiting plate 31 and then forms an inclined state for slag discharge. The eccentric effect of the connection position between the protection main body 20 and the sliding rod 32 can be used to promote slag discharge, further optimizing the slag discharge method, which is more labor-saving and convenient.

[0036] The working principle of the present utility model: The pressure head is fixedly installed at the end of the output shaft of the oil cylinder. The oil cylinder is used to push the pressure head 11 downward to approach the test bench 12. Then the pressure applied by the pressure head 11 to the test bench 12 is displayed, that is, the pressure received by the concrete test block, so as to realize the anti-pressure detection of the test block.

[0037] Two symmetrically arranged protection bodies 20 jointly shield the test bench 12 and form a protection barrier around the test bench 12. When the test block is crushed by pressure and breaks, the protection bodies 20 and the plug board 21 can limit the splashing of the broken pieces. The protection body 20 with an inclined bottom can collect the crushed stones. When the protection body 20 slides, the protection body 20 drives the sliding rod 32 to slide in the chute of the guide rod 30. When the front of the protection body 20 slides to the front of the base 10 and is in a suspended state, the concrete in the protection body 20 and the gravity of the protection body 20 itself will cause the protection body 20 to flip towards the limit plate 31. The bottom of the protection body 20 flips to fit the top surface of the limit plate 31 and then forms an inclined state for discharging slag. A handle is fixedly arranged on the wall surface of the plug board 21. Pulling the handle drives the plug board 21 to move upward. The plug board 21 drives the convex rib 22 to slide in the slot 23. Then the bottom of the plug board 21 is separated from the protection body 20. Cooperating with the reversible protection body 20, the protection body 20 can be kept in an inclined posture to pour out the collected concrete fragments.
