Abstract
Description
Technical Field
[0001] The utility model relates to the field of concrete testing, in particular to a concrete impact testing device. Background Art
[0002] There are two main test methods for concrete impact resistance testing: static load test and dynamic load test. Among them, dynamic load test can be divided into direct impact test and free drop hammer test. The direct impact test is to let the impact tester fall freely from a certain height and collide with the surface of the test piece to measure the dynamic response of the test piece under the impact load. It is usually used to evaluate the impact resistance of concrete. The free drop hammer test is to drop a free drop hammer loaded with a certain weight. The drop hammer observes and compares the deformation and crack degree formed on the concrete structure to be tested to derive its impact resistance. The existing impact test device has a simple structure, and it is troublesome to clean up the concrete after the test. Utility Model Content

Specific Embodiments
[0013] Embodiment:
[0014] As Figure 1 , this embodiment provides a concrete impact testing device, including a box body 1. Two cross bars 2 are arranged in the middle of the box body 1. A bearing plate 3 is arranged on the two cross bars 2. The bottom of the box body 1 is a hollow funnel structure 4. A recycling box 5 is arranged below the box body 1. A support beam 6 is arranged in the middle of the box body 1. The support beam includes a cross beam 7. A first cylinder 8 is arranged above the cross beam 7. A guide cylinder 9 is arranged on one side of the first cylinder 8. The end of the piston rod of the first cylinder 8 is fixedly connected to a connecting rope 10. The connecting rope 10 passes through the guide cylinder 9 and is connected to a drop hammer 11. A second cylinder 12 is arranged at the bottom of the cross beam 7. The piston rod of the second cylinder 12 is connected to an electromagnet 13. The guide cylinder 9 is arranged in the middle of the cross beam 7. The bearing plate 3 is arranged at the middle position of the bottom of the box body 1. The second cylinder 12 is arranged on the side of the guide cylinder 9 away from the first cylinder 8. The distance between the second cylinder 12 and the guide cylinder 9 is adapted to the size of the drop hammer 11.
[0015] When this embodiment is in use, according to the test requirements, control the second cylinder 12 to drive the electromagnet 13 to lift to an appropriate height. The first cylinder 8 lifts the drop hammer to the height of the electromagnet. The electromagnet adsorbs the drop hammer. Then the first cylinder 8 returns to the initial position. Place the concrete block to be tested on the bearing plate 3. The electromagnet is powered off, so that the drop hammer falls freely and drops onto the concrete block to be tested. Observe the results. After the test, clean the concrete around to the bottom recycling box, and clean the bearing platform.
[0016] The present utility model provides an idea and method for a concrete impact testing device. There are many methods and ways to specifically implement this technical solution. The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present utility model. Each component not clearly defined in this embodiment can be implemented by using the existing technology.
