In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The floor impact testing device according to the embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-Figure 3As shown, the floor impact test device according to the embodiment of the utility model includes: a base plate 1, a conduit 7 and an impact hammer 9, the base plate 1 carries a floor 10; the conduit 7 is vertically installed on the base plate 1 through a moving assembly, the conduit 7 can move above the floor 10 driven by the moving assembly, and a vertically arranged channel is provided in the conduit 7; the impact hammer 9 is confined in the channel of the conduit 7, and the impact hammer 9 is released when the conduit 7 moves to the corresponding position above the floor 10, and the impact hammer 9 falls to perform an impact test on the floor 10.

[0027] In other words, every corner and middle part of the floor 10 needs to be tested. The manual grabbing of the steel ball test cannot ensure that the steel ball falls accurately on the detection position of the floor 10, and the moving component can drive the conduit 7 to move above the floor 10, ensuring that the conduit 7 is vertically above the test position, and the channel in the conduit 7 is vertically arranged, thereby ensuring that the impact hammer 9 falls vertically on the test position, thereby ensuring the test accuracy.

[0028] Furthermore, a plurality of limit holes 71 are provided on the conduit 7 and are arranged to penetrate the conduit 7 in the direction of the wall thickness. The plurality of limit holes 71 are arranged at intervals in the vertical direction. A limit pin 8 is inserted into the limit hole 71. The limit pin 8 abuts against the lower end of the impact hammer 9 to limit the height of the impact hammer 9 in the conduit 7.

[0029] That is, when the limit pin 8 is inserted into the limit hole 71, the movement of the impact hammer 9 in the channel is blocked, so that the impact hammer 9 is above the limit pin 8 during each test, ensuring the height consistency of each test and improving the test accuracy. In addition, the position of the limit pin 8 can be changed according to different test requirements, so as to perform impact tests at different heights. Of course, the conduit 7 can also be marked with scales to facilitate personnel to select different heights for testing.

[0030] In this embodiment, the moving assembly includes a column 2, a mounting block 3, a guide rod 4 and a mounting plate 5. The column 2 is rotatably mounted on the bottom plate 1, and the column 2 is located on one side of the floor 10; the mounting block 3 is mounted on the upper end of the column 2; the guide rod 4 is horizontally arranged, and one end of the guide rod 4 is fixed on the mounting block 3; the mounting plate 5 is slidably mounted on the guide rod 4 through a slider 6, and the middle part of the guide tube 7 is mounted on the mounting plate 5. Further, the number of guide rods 4 is two, the two guide rods 4 are parallel, and the two guide rods 4 are on the same horizontal plane, the guide tube 7 is located between the two guide rods 4, and the two guide rods 4 are provided to keep the mounting plate 5 stable when sliding. Furthermore, the movement trajectory of the guide rod 4 constitutes a sector surface, and the positive projection of the sector surface on the bottom plate 1 covers the floor 10.

[0031] That is to say, the column 2 mainly plays a supporting and rotating role, driving the entire guide rod 5, the mounting plate 5 and the conduit 7 to rotate on the horizontal plane, and the conduit 7 can slide along the guide rod 4, so that the conduit 7 can move on a fan-shaped surface. It is only necessary to ensure that the floor 10 falls within the fan-shaped surface, so that the conduit 7 can be impact tested at any position on the upper surface of the floor 10.

[0032] According to an embodiment of the utility model, there is a gap between the lower end of the conduit 7 and the floor 10, and the length of the impact hammer 9 is greater than 50 mm. This design can prevent the conduit 7 and the floor 10 from abutting against each other to generate air pressure in the channel to affect the test results, and on the other hand, it ensures the guidance of the impact hammer 9 and can prevent the impact hammer 9 from bouncing to other places after falling, thereby ensuring the safety of personnel.

[0033] According to an embodiment of the utility model, the impact hammer 9 is a cylindrical member, the outer diameter of the impact hammer 9 matches the inner diameter of the channel, and the lower end of the impact hammer 9 is a semicircular spherical surface. In this embodiment, the outer diameter of the impact hammer 9 is slightly smaller than the inner diameter of the channel, so that the channel can guide the impact hammer 9 to ensure the test accuracy.

[0034] Preferably, the bottom plate 1 has a plurality of support blocks 11, the upper surfaces of the plurality of support blocks 11 are on the same horizontal plane, and the support blocks 11 are used to support the floor 10. There are four support blocks 11, and the four support blocks 11 are located at the four corners of the floor 10. The support blocks 11 can support the floor 10 to ensure that the floor 10 is on a horizontal plane, and can simulate the four-corner support of the floor 10 when it is actually used (the anti-static floor needs to be erected to a certain height through the four corners before use), so that the test results are more accurate.

[0035] The beneficial effect of the utility model is that the utility model uses the conduit 7 to guide the falling impact process of the impact hammer 9, ensuring that the impact hammer 9 can fall to the corresponding test position on the floor 10, ensuring the impact accuracy, and improving the test accuracy. At the same time, the conduit 7 can be moved under the drive of the moving component, so as to move to any position above the floor 10 for testing, which is more widely applicable and makes the impact test faster and more accurate.
