Description

Technical Field

[0001] The utility model relates to the field of testing equipment, in particular to floor testing equipment. Background Art

[0002] At present, in the flooring industry, most of the lock-in flooring tests the buckle tension data. The test method is to use one end of the tensile machine clamp to clamp one side of the male groove and the other end of the female groove after the male and female grooves are assembled, and then the male and female grooves are pulled apart. The data obtained is the buckle tension data. However, this test can only know the horizontal force of the lock-in floor after the installation of the floor buckle, and cannot know the changes in the floor buckle after the vertical force, such as whether the buckle will be damaged by placing heavy objects on the floor, and the lock-in floor is laid on the ground with pits. The buckle force changes when people walk or the chairs turn cannot be evaluated, which leads to a large blind spot in the design and selection of floor buckles; in addition, the hardness of the floor is also an important indicator for measuring the performance and quality of the floor. Therefore, it is usually necessary to test the hardness of the floor. At the same time, preparing two test equipment consumes a long time when replacing, and the test efficiency is low. Utility Model Content

[0003] In view of this, in order to solve the above problems, the utility model provides a floor testing device.

[0004] A floor testing device comprises a pressure mechanism and a fixing mechanism, wherein the pressure mechanism comprises a pressure driving member, a pressure sensor and a pressure head assembly, wherein one end of the pressure sensor is connected to the output end of the pressure driving member, and the other end is detachably connected to the pressure head assembly, wherein the pressure head assembly comprises at least two test pressure heads, and the fixing mechanism comprises a first slide rail, wherein a test fixture and a lifting device are mounted on the first slide rail, wherein the lifting device is slidably connected to the first slide rail, and wherein the lifting device comprises a lifting driving member and a support plate, wherein the support plate is connected to the output end of the lifting driving member.

[0005] In the above technical solution, the pressure driving component can drive the connected pressure sensor and the pressure head assembly to move up and down to provide a test force. The pressure sensor is located before the pressure driving component and the pressure head assembly to detect the specific value of the force. The pressure head assembly includes at least two test pressure heads. The shape and structure of the two test pressure heads can be replaced according to the type of test to be performed. Normally, the two test pressure heads are used to test the vertical strength and hardness of the floor respectively. The fixing mechanism is arranged below the pressure head assembly, wherein the test fixture and the lifting device are both installed on the first slide rail. The lifting device is slidably connected to the first slide rail. The lifting device can be adjusted to a suitable position through the first slide rail, so that when testing the hardness of the floor, the lifting device can provide support to ensure the normal progress of the test. The test fixture is used to fix the floor test sample that needs to be tested. When the floor test sample is fixed on the test fixture for testing, the test pressure head presses down the buckle-shaped part of the floor test sample until it breaks. The maximum force value that causes the buckle-shaped part of the floor to break is obtained through the pressure sensor, thereby calculating the vertical strength of the floor buckle. Subsequently, the sliding jacking device is moved to the bottom of the floor test sample, and the support plate is driven upward by the lifting drive member so that the top surface of the support plate contacts the floor test sample, thereby providing support for the floor test sample. Subsequently, the test pressure head is pressed down, and the hardness data of the floor is obtained according to the indentation left on the floor test sample and the data of the pressure sensor, so that the vertical strength and hardness test of the floor can be completed on the same test equipment, thereby improving the test efficiency and practicality.

[0006] Furthermore, as a preferred technical solution, the test fixture is provided with a test slot for placing the test product, and openings are provided on both sides of the test slot.

[0007] In the above technical solution, both the left and right sides of the test slot are open, so that both the left and right ends of the floor test sample can extend a part of the test slot. Because after one side of the floor test sample is subjected to pressure, the performance of its surrounding parts will also be affected to a certain extent. Therefore, by performing different performance tests on the left and right sides of the floor test sample, the influence of the previous test can be effectively avoided and the accuracy of the test results can be improved.

[0008] Furthermore, as a preferred technical solution, the pressure mechanism also includes a connecting shaft, one end of which is rotatably connected to the output end of the pressure driving member, and the other end of which is detachably connected to the pressure head assembly.

[0009] In the above technical solution, the top end of the connecting shaft is rotatably connected to the output end of the pressure driving member. When testing some lock-type floors with different angles, the angle of the pressure head assembly can be adjusted by rotating the connecting shaft to adapt to the testing of lock-type floors with different angles, thereby improving applicability. The pressure head assembly is detachably connected to the connecting shaft, and pressure heads of different shapes and structures can be replaced according to the test type.

The strength test pressure head and the hardness test pressure head are used to perform buckle-type vertical strength test and floor hardness test on the floor respectively.

[0012] Further, as a preferred technical solution, the contact end of the strength testing indenter is arc-shaped, and the hardness testing indenter is spherical.

[0013] In the above technical solution, the contact end between the strength test indenter and the floor is an arc shape with a certain curvature, and the curvature radius of the arc contact surface is relatively large, which can make the pressure distribution more uniform, reduce local stress concentration, and make the test results more accurate. The hardness test indenter is spherical in shape and is used to press into the floor test sample, so as to calculate the hardness data of the floor through the indentation.

[0014] Furthermore, as a preferred technical solution, a first slide plate and a second slide plate are slidably connected to the first slide rail, and the test fixture and the lifting device are respectively installed on the first slide plate and the second slide plate.

[0015] In the above technical solution, the first slide plate and the second slide plate are both slidably connected to the first slide rail and can slide left and right along the first slide rail. The test fixture and the lifting device are respectively installed on the first slide plate and the second slide plate. By moving the first slide plate and the second slide plate, the test fixture and the lifting device are adjusted to the appropriate position to ensure the normal progress of the test.

[0016] Furthermore, as a preferred technical solution, the fixing mechanism further includes a second slide rail, the first slide rail and the second slide rail are vertically arranged and slidably connected, and the second slide rail is provided with a locking structure.

[0017] In the above technical solution, the second slide rail is located at the bottom of the first slide rail and remains perpendicular to the first slide rail. The first slide rail is slidably connected to the second slide rail, so that the first slide rail can move forward and backward along the second slide rail, further facilitating the adjustment of the position of the test fixture and the lifting device. The second slide rail is also provided with a locking structure, which is used to lock the first slide rail after it moves to a suitable position to prevent the first slide rail from moving during the test and ensure the accuracy of the test results.

[0018] Furthermore, as a preferred technical solution, both the first slide plate and the second slide plate are provided with lock buckles, and the first slide rail is provided with lock grooves matching with the lock buckles.

[0019] In the above technical solution, the first slide plate and the second slide plate are both provided with a lock, and a lock groove matching the lock is opened on the inner side of the first slide rail. The lock and the lock groove are used to fix the first slide plate and the second slide plate to prevent the first slide plate and the second slide plate from moving during the test to avoid affecting the test results.

[0020] Furthermore, as a preferred technical solution, the lifting device is provided with an in-position sensor, and the in-position sensor is installed on the side of the support plate.

[0021] In the above technical solution, a position sensor is installed on one side of the support plate, and the position sensor is used to detect the position of the support plate to ensure that the support plate and the bottom surface of the floor test sample are in place, thereby preventing inaccurate test results due to loose fit.

[0022] Furthermore, as a preferred technical solution, a control device is provided on one side of the pressure mechanism and the fixing mechanism, and the control device includes a control screen.

[0023] In the above technical solution, the control device is used to control the operation of the entire device and receive data from the pressure sensor and the position sensor.

The lifting device is then adjusted to a suitable position through the first slide rail to provide support for the floor, and then the other test pressure head presses down to test the hardness of the floor. The present application obtains vertical strength and hardness data of the floor by having at least two test pressure heads in the pressure head assembly press down on the floor test sample respectively, so that vertical strength and hardness tests can be performed on the floor test sample respectively, that is, different types of tests on the floor can be implemented on the same testing equipment, effectively improving test efficiency and practicality.
