Description

Technical Field

[0001] This utility model belongs to the field of testing technology, and in particular relates to a device for testing the compressive strength of concrete. Background Technology

[0002] Concrete is a general term for engineering composite materials made by binding aggregates together with cementing materials. The term "concrete" usually refers to cement concrete, which uses cement as the cementing material, sand and gravel as aggregates, and water in a specific ratio, and is widely used in civil engineering. Concrete testing requires compressive strength testing instruments; however, existing instruments have poor protective capabilities, and concrete is prone to breakage during testing, causing debris to fly and potentially injure nearby personnel.

[0003] Concrete is an indispensable material in modern construction projects. Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, i.e., fresh concrete or concrete mix; and the hard state after hardening, i.e., hardened concrete or concrete. Concrete strength grade is determined by the standard value of cubic compressive strength. Concrete quality inspection can be divided into three main aspects: internal quality, surface quality, and dimensional quality. Surface quality and dimensional quality can be assessed using simple measurement and observation methods, while compressive strength requires further in-depth testing.

[0004] Chinese Patent Application No. CN202122575873.3 discloses a device for testing the compressive strength of concrete used in transportation civil engineering. The device includes a frame and a testing mechanism mounted on the frame. A moving device for moving the position of a concrete test block is mounted on the frame. The moving device includes a testing platform rotatably mounted on the frame via a rotating shaft, on which the concrete test block is placed; a pushing cylinder mounted on the frame; a pushing block fixedly connected to the piston rod of the pushing cylinder; and a rotating mechanism mounted on the frame and used to drive the testing platform to rotate. This application uses the pushing cylinder to activate the pushing block, which in turn moves the concrete test block, and rotates the testing platform to adjust the position of the concrete test block, thereby completing the strength testing at various positions of the concrete test block. This reduces the time required to move the test block and improves testing efficiency.

[0005] However, when the device tests the compressive strength of concrete, the concrete may break apart. The broken concrete is easily splashed onto the testing platform, which can contaminate the platform and make it difficult for staff to clean it. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned technical problems by providing a concrete compressive strength testing device that effectively shakes residual concrete from the clamping assembly into the collecting assembly, thus preventing it from affecting the clamping effect.

[0007] In view of this, the present invention provides a concrete compressive strength testing device, including a press, wherein the press base plate is provided with: A collection component for collecting concrete debris; A clamping assembly for clamping concrete; The clamping component is equipped with a mortar-shaking structure to shake off any residual concrete on the clamping component into the collecting component.

[0008] In this technical solution, the collecting component can collect concrete debris, making it easier for staff to clean the testing platform. In addition, the clamping component can hold the concrete in place so that it does not move around when pressed down. The dust-shaking structure can shake off the concrete remaining on the clamping component into the collecting component, preventing it from affecting the clamping.

[0009] Furthermore, the collection component includes a collection box, the bottom of which has a groove, a collection container is slidably connected in the groove, and a handle is installed on the collection container.

[0010] Furthermore, the clamping assembly includes: Clamping blocks, the clamping blocks are L-shaped, there are two clamping blocks, the two clamping blocks are arranged opposite each other and can approach each other to form a square space with the same shape as the concrete test block; A drive assembly for driving two clamping blocks to move closer or further apart.

[0011] Furthermore, the heads of the clamping blocks are comb-shaped, with the comb teeth of the two clamping block heads being staggered.

[0012] In this technical solution, by making the comb teeth of the two clamping blocks staggered, when the concrete test block is small, the comb teeth of the two clamping blocks can interweave and avoid collision, so that the two sets of clamping blocks can fix small-sized concrete.

[0013] Furthermore, the driving component is a cylinder, and the cylinder output end is fixedly connected to the clamping block.

[0014] Furthermore, the clamping block is disposed inside the collection box, and the cylinder is disposed outside the collection box, with the piston rod of the cylinder passing through the wall of the collection box and fixedly connected to the clamping block.

[0015] Furthermore, the dust-shaking structure shakes the dust by causing the clamping assembly to swing circumferentially.

[0016] Furthermore, the cylinder is fixedly connected to the swing plate, and a swing pin is fixedly connected to the end of the swing plate away from the cylinder. An arc-shaped groove is provided on the side wall of the collection box, and the swing pin is slidably disposed in the arc-shaped groove. A positioning hole is provided on the side wall of the collection box concentrically with the arc-shaped groove. The positioning hole is used for the cylinder piston rod to pass through. The dust shaking structure also includes a fixing structure for fixing the swing plate and preventing the swing plate from rotating.

[0017] Furthermore, the fixing structure includes: A limiting plate is fixedly installed on the outer wall of the collection box, and there are two limiting plates arranged opposite to each other. A rotating rod is disposed between two limiting plates and is in contact with the limiting plates; A positioning rod, one end of which is fixedly mounted on the swing plate and the other end is rotatably connected to a rotating rod, which can rotate away from the limiting plate or rotate into the space between the two limiting plates; A limiting spring is provided, with one end fixedly connected to the outer wall of the collection box and the other end connected to the rotating rod. The limiting spring always has the tendency to pull the rotating rod between the two limiting plates.

[0018] In this technical solution, under normal circumstances, the rotating rod is located between the two limiting plates and is limited by the two limiting plates, so it cannot swing. Thus, the swing plate cannot swing. When it is necessary to shake off the concrete on the clamping assembly, the rotating rod is rotated by force to move the rotating rod outside the two limiting plates. At this time, the rotating rod can be swung to make the swing plate swing, which drives the entire clamping assembly to swing, thereby achieving the purpose of shaking off the concrete.

[0019] The beneficial effects of this utility model are: 1. The collection component can collect concrete debris, making it easier for staff to clean the testing platform. In addition, the clamping component can hold the concrete in place and prevent it from moving around when it is pressed down. The dust-shaking structure can shake off the concrete remaining on the clamping component into the collection component to prevent it from affecting the clamping.

[0020] 2. By staggering the comb teeth at the heads of the two clamping blocks, when the concrete test block is small, the comb teeth at the heads of the two clamping blocks can interweave, thus preventing collisions and allowing the two sets of clamping blocks to fix small-sized concrete.

[0021] 3. Under normal circumstances, the rotating rod is located between the two limiting plates and is limited by the two limiting plates, so it cannot swing. Thus, the swing plate cannot swing. When it is necessary to shake off the concrete on the clamping assembly, the rotating rod is rotated by force to move the rotating rod outside the two limiting plates. At this time, the rotating rod can be swung to make the swing plate swing, which will drive the entire clamping assembly to swing, thereby achieving the purpose of shaking off the concrete.

[0029] Example 1: like Figure 1-4 As shown, A concrete compressive strength testing device includes a press 1, and the base plate of the press 1 is equipped with: Collection component 2, which is used to collect concrete debris; Clamping assembly 3, which is used to clamp concrete; The clamping component 3 is provided with a mortar-shaking structure 18, which is used to shake off the residual concrete on the clamping component 3 into the collecting component 2.

[0030] The collection component 2 can collect concrete debris, making it easier for staff to clean the testing platform. In addition, the clamping component 3 can clamp the concrete to ensure that the concrete is in the correct position and does not move around when it is pressed down. The dust shaking structure 18 can shake the concrete remaining on the clamping component 3 into the collection component 2 to prevent it from affecting the clamping.

[0031] The collection component 2 includes a collection box 4, the bottom of which is provided with a groove 6, and a collection container 5 is slidably connected in the groove 6. A handle 7 is installed on the collection container 5.

[0032] The clamping component 3 includes: Clamping blocks, the clamping blocks are L-shaped, there are two clamping blocks, the two clamping blocks are arranged opposite each other and can approach each other to form a square space with the same shape as the concrete test block; A drive assembly for driving two clamping blocks to move closer or further apart.

[0033] The head of the clamping block is shaped like a comb, and the comb teeth 8 of the two clamping block heads are staggered.

[0034] By staggering the comb teeth 8 at the heads of the two clamping blocks, when the concrete test block is small, the comb teeth 8 at the heads of the two clamping blocks can interweave and avoid collision, thus allowing the two sets of clamping blocks to fix small-sized concrete.

[0035] The driving component is a cylinder 9, and the output end of the cylinder 9 is fixedly connected to the clamping block.

[0036] The clamping block is installed inside the collection box 4, and the cylinder 9 is installed outside the collection box 4. The piston rod of the cylinder 9 passes through the wall of the collection box 4 and is fixedly connected to the clamping block.

[0037] Example 2: like Figure 3-6 As shown, The dust-shaking structure 18 shakes dust by causing the clamping assembly 3 to swing circumferentially.

[0038] The cylinder 9 is fixedly connected to the swing plate 11. A swing pin 10 is fixedly connected to the end of the swing plate 11 away from the cylinder 9. An arc-shaped groove 12 is provided on the side wall of the collection box 4. The swing pin 10 is slidably disposed in the arc-shaped groove 12. A positioning hole 13 is provided on the side wall of the collection box 4 concentric with the arc-shaped groove 12. The positioning hole 13 is used for the piston rod of the cylinder 9 to pass through. The dust shaking structure 18 also includes a fixing structure for fixing the swing plate 11 and preventing the swing plate 11 from rotating.

[0039] The fixing structure includes: Limiting plate 14, the limiting plate 14 is fixedly installed on the outer side wall of the collection box 4, and there are two limiting plates 14 arranged opposite to each other; Rotating rod 15, the rotating rod 15 is disposed between two limiting plates 14 and is in contact with the limiting plates 14; The positioning rod 16 has one end fixedly mounted on the swing plate 11 and the other end rotatably connected to the rotating rod 15. The rotating rod 15 can rotate away from the limiting plate 14 or rotate into the space between the two limiting plates 14. The limiting spring 17 is fixedly connected at one end to the outer wall of the collection box 4 and at the other end to the rotating rod 15. The limiting spring 17 always has the tendency to pull the rotating rod 15 between the two limiting plates 14.

[0040] Under normal circumstances, the rotating rod 15 is located between the two limiting plates 14 and is limited by the two limiting plates 14, so it cannot swing. This prevents the swing plate 11 from swinging. When it is necessary to shake off the concrete on the clamping assembly 3, the rotating rod 15 is rotated by force, so that the rotating rod 15 moves outside the two limiting plates 14. At this time, the rotating rod 15 can be swung to make the swing plate 11 swing, which drives the clamping assembly 3 to swing as a whole, thereby achieving the purpose of shaking off the concrete.
