Description

Technical Field

[0001] The utility model relates to the technical field of testing machine equipment, in particular to an impact testing machine for recycled concrete finished products. Background Technique

[0002] Concrete is one of the most important civil engineering materials in modern times. It is an artificial stone prepared by mixing cementitious materials, granular aggregates (also known as aggregates), water, and, if necessary, admixtures and fillers in a certain proportion, uniformly stirred, densely formed, and cured and hardened. Concrete has the characteristics of rich raw materials, low price, and simple production process, so its consumption is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades.

[0003] The application number is CN202322288331.7, which discloses a concrete impact testing device, including a testing table. A support column is provided on the testing table. A top plate is provided at one end of the support column away from the testing table. An impact assembly is arranged on the testing table. The impact assembly includes an impact ball for hitting the test block. An installation plate is provided below the testing table. A third rotating motor is provided on the installation plate. A rotating hole is opened on the testing table. The output end of the third rotating motor is fixedly provided with a turntable. The turntable is located in the rotating hole. A test block placement groove is provided on the turntable. The cross-sectional area of the test block placement groove is larger than the cross-sectional area of the test block. When performing impact testing, there is always a test block placement groove directly below the impact ball. The utility model is used to solve the technical problem that when the existing concrete impact testing device is in use, when a large number of samples or control tests of samples of the same batch need to be carried out, the samples need to be frequently replaced, resulting in low testing efficiency mentioned in the background technique.

[0004] The above-mentioned disclosed concrete impact testing device has the following defects: when the testing device detects the stamping of concrete, a large amount of impact force will be generated when the impact block stamps the concrete. The concrete needs to be fixed, otherwise it is very easy to be driven to move and misalign by the impact force of the impact block. This structure only has one placement groove and cannot fix concrete of different sizes, reducing the flexibility of the device.

[0005] It can be seen that the existing impact testing device does not have the function of fixing concrete of different sizes, and it is necessary to improve the existing deficiencies to provide a function that can fix concrete of different sizes. Content of the Utility Model

[0006] The purpose of the utility model is to provide an impact testing machine for recycled concrete finished products to solve the problems mentioned in the above background technique.

[0007] To solve the above technical problems, the utility model is realized through the following technical solutions:

The clamping block is slidably connected to the inner wall of the placing block. A compression spring is sleeved on the outer wall of the thin rod of the two telescopic rods. Two ends of the compression spring are located between the thick rod of the telescopic rod and the clamping block. The purpose of such a setting is that during the use of the testing machine, components inside the bottom shell control the pressing rod to press down. The cover plate protects the components inside the bottom shell. The support seats isolate the bottom shell from the ground. The lock catches fix between the bottom shell and the cover plate. The turning handle is convenient for lifting the device. The design of the fixing seat makes the cover plate perpendicular to the fixing seat. Place the concrete block on the placing block. Limit the two ends of the soil block through the two side blocks of the placing block. Fix one side of the soil block through the stop block. The two pneumatic components drive the telescopic rods to push forward. The telescopic rods drive the clamping blocks to press and fix the other side of the soil block forward. The limiting frame limits the pressing rod and the sliding rod. When the pressing rod presses down, the bottom end movable rod of the pressing rod is driven to rotate downward perpendicular to the cover plate. The bottom end of the movable rod drives the sliding rod to slide downward in the limiting frame. Drive the stamping plate to press down on the concrete on the clamping structure for testing. When it is necessary to remove the soil block, pull the push handle. The push handle drives the clamping block to move backward. The clamping block squeezes the compression spring to contract towards one end of the telescopic rod. After taking out the soil block, the compression spring rebounds to drive the clamping block to reset. The clamping structure can clamp and fix concretes of different sizes, improving the flexibility of the device.

[0009] Furthermore, the testing machine comprises a bottom shell. Support seats are arranged around the bottom surface of the bottom shell.

[0010] Furthermore, a lock catch is installed on the outer wall of one side of the cover plate. One end of the lock catch extends to the outer wall of the bottom shell. A turning handle is rotatably connected to the inner wall of one side of the bottom shell. The purpose of such a setting is that during the use of the testing machine, the lock catch fixes between the bottom shell and the cover plate. The turning handle is convenient for lifting the device.

[0011] Further, a fixing seat is provided on the outer wall of one side at the top of the cover plate parallel to the clamping structure, and a limiting frame is provided on the outer wall of the fixing seat close to the clamping structure. The purpose of such a setting is that during the use of the testing machine, the design of the fixing seat makes the cover plate perpendicular to the fixing seat, and the limiting frame limits the pressure rod and the sliding rod.

[0012] Further, pressure rods are connected to the inner walls on both sides of the limiting frame, and movable rods are hinged to the outer walls on both sides of the bottom of the pressure rod. The movable rods and the hinged ends of the two movable rods are on the same coaxial line. The purpose of such a setting is that during the use of the testing machine, when the pressure rod is pressed down, the movable rod at the bottom end of the pressure rod is driven to rotate downward perpendicular to the cover plate.

[0013] Further, a sliding rod is hinged to the side where the two movable rods are close to each other. The rod body of the sliding rod is slidably connected to the inner wall at the bottom end of the limiting frame, and a punching plate is hinged to the bottom end of the sliding rod. The purpose of such a setting is that during the use of the testing machine, the bottom end of the movable rod drives the sliding rod to slide downward in the limiting frame, and the sliding rod drives the punching plate to press downward on the concrete on the clamping structure for punching tests.

[0014] Compared with the prior art, the present utility model has the following beneficial effects:

[0015] Through the arrangement of the placing block, the clamping block and the pneumatic components, the present utility model drives the telescopic rod to push forward by two pneumatic components.
