Description

Technical Field

[0001] The present application relates to the technical field of floor testing, and in particular to a test device and method for testing the rolling load of an anti-static movable floor. Background Art

[0002] Anti-static raised floors are elevated floors connected by brackets and beams. The space between the raised floor and the base floor or floor not only accommodates the crisscrossing of cables and pipelines, but also, through design and placement of ventilation holes in appropriate locations on the raised floor, can meet air conditioning requirements such as static pressure supply. Therefore, anti-static raised floors are widely used in computer rooms, programmable switch rooms, audio-visual classrooms, power dispatch rooms, weak current machine rooms, clean workshops, and other places where dust protection, anti-static, and overhead conditions are required.

[0003] Anti-static raised floor is composed of floor panels and floor support system, such as Figure 1 As shown, the anti-static raised access floor includes floor panels 01, crossbeams 02, cushions 03, locking devices 04, and adjustable supports 05. The national standard GB / T36340-2018, "General Specification for Anti-static Raised Access Floors," specifies that the load-bearing capacity of the floor panels of anti-static raised access floors must meet certain standards and provides a test method for testing the rolling load of these panels. For example, the rolling load of the floor panels of a standard anti-static raised access floor is tested using a load value (10 times). Under a load value of 3560N, the deflection must be less than or equal to 2mm, and the residual deformation must be less than or equal to 0.5mm.

[0035] The present application provides a test device for testing the rolling load of an anti-static movable floor, comprising: a test bench 1, a guide rail 2, a sliding bracket 3, a loading device 4, a fixed beam 5, and a control device 6; the guide rail 2 is fixed to the test bench 1; the sliding bracket 3 is slidably connected to the guide rail 2, and at least one limit device 21 is provided at each end of the guide rail 2 in the longitudinal direction. The sliding bracket 3 is connected to a motor 31, wherein the limit device 21 and the motor 31 control the reciprocating motion of the sliding bracket 3 on the guide rail 2; the loading device 4 is fixed above the sliding bracket 3 by the fixed beam 5, and a pressure sensor is provided on the loading device 4, and a rolling wheel 41 is connected to the bottom of the loading device 4; the sliding bracket 3 is also provided with a displacement sensor 32 and a fixing device 33 for fixing a test plate 7, wherein the displacement sensor 32 is located on the radial center axis of the rolling wheel 41 and below the installed test plate 7; the motor 31, loading device 4, limit device 21, pressure sensor, and displacement sensor 32 are all connected to the control device 6.

[0036] Figure 2 It is a structural schematic diagram of a test device for testing the rolling load of an anti-static movable floor in an embodiment of the present application. Figure 3 It is a structural schematic diagram of a test device for testing the rolling load of an anti-static movable floor after installing a test plate in an embodiment of the present application.

[0037] The test device for testing the rolling load of the anti-static movable floor provided in the embodiment of the present application is as follows: Figure 1 and Figure 2As shown, when testing the floor panels of the anti-static movable floor, the test panel 7 is installed on the fixing device 33, wherein the test panel 7 described in the embodiment of the present application refers to the floor panel of the anti-static movable floor that needs to be tested. According to the load-bearing type of the test panel 7, the corresponding load value of the loading device 4 is set, and the corresponding model of the rolling wheel 41 is installed. The loading device 4 is provided with a lifting device, which can control the distance between the rolling wheel 41 and the test panel 7. The motor 31 provides power for the movement of the sliding bracket 3, so that the sliding bracket 3 drives the test panel 7 to move on the guide rail 2. A limit device 21 is provided at each end of the guide rail 2. The positions of the two limit devices 21 are installed so that the movement stroke of the sliding bracket 3 on the guide rail meets the requirements of the "General Specifications for Anti-static Movable Floors". The limit device 21 and the motor 31 jointly control the reciprocating motion of the sliding bracket 3 on the guide rail 2. When the sliding bracket 3 is controlled to move to a preset position at one end of the guide rail 2, the limit device 21 installed at the end of the guide rail 2 is triggered, and the motor 31 drives the sliding bracket 3 to move in the opposite direction to the preset position at the other end of the guide rail 2. The limit device 21 installed at the other end of the guide rail 2 is triggered again, and the motor 31 again drives the sliding bracket 3 in the opposite direction, thus achieving reciprocating motion. During the reciprocating motion of the sliding bracket 3, the rolling wheel 41 rolls on the test plate 7, performing a rolling load test on the test plate 7. The displacement sensor 32 located below the test plate 7 collects the displacement value generated by the rolling wheel 41 during the rolling process on the test plate 7 in real time, which is used to calculate the deflection and residual deformation of the test plate. It should also be noted that the limit device 21 in the embodiment of the present application is not only used to limit the movement range of the sliding bracket 3, but also to record the number of times the sliding bracket 3 reciprocates on the guide rail, that is, the number of times the test plate 7 rolls over the rolling wheel 41.

[0038] Among them, the motor 31, the loading device 4, the limit device 21, the pressure sensor and the displacement sensor 32 can all be connected to the control device 6. The control device 6 can realize the fully automatic test of the rolling load of the anti-static movable floor according to the data collected by the limit device 21, the pressure sensor and the displacement sensor 32. Specifically, after the test plate 7 is installed on the fixing device 33, the control device 6 controls the lifting and lowering of the loading device 4 and the load value loaded by the loading device 4 through the pressure sensor, controls the motor 31 to drive the sliding bracket 3 to reciprocate on the guide rail 2, and the control device 6 can control the sliding bracket 3 to stop moving according to the displacement value collected by the displacement sensor 32. For example, if the maximum displacement value collected by the displacement sensor 32 exceeds the preset displacement value, the control device 6 controls the sliding bracket 3 to stop moving and records the number of cycles collected by the limit device 21. The control device 6 can also control the sliding bracket 3 to stop moving according to the number of cycles collected by the limit device 21. For example, if the number of cycles collected by the limit device 21 reaches the preset number of cycles, the control device 6 controls the sliding bracket 3 to stop moving and records the maximum displacement value collected by the displacement sensor 32.

[0039] In one specific embodiment, the limit device 21, the pressure sensor, and the displacement sensor 32 can all be connected to the control device 6 via wired communication. In another embodiment, the limit device 21, the pressure sensor, and the displacement sensor 32 can also be connected to the control device 6 via wireless communication. For example, the limit device 21, the pressure sensor, the displacement sensor 32, and the control device 6 are all provided with a Bluetooth module for wireless communication connection, and the limit device 21, the pressure sensor, the displacement sensor 32 and the control device 6 are connected via the Bluetooth module.

[0040] In another specific embodiment, Figure 4 As shown, the test device for testing the rolling load of the anti-static movable floor described in the embodiment of the present application also includes an operation display interface 8, and the operation display interface 8 is connected to the control device 6. The operation display interface 8 can be a display screen of an electronic device connected to the control device 6, or it can be a separate operation display interface 8 for operation, wherein the electronic device can be a computer, an iPad or a mobile phone terminal, etc. The data collected by the limit device 21, the pressure sensor, and the displacement sensor 32 can be displayed in real time on the operation display interface 8. For example, the operation display interface 8 can simultaneously display the current displacement value, the current load value, and the current number of cycles; and the user can control the operation of each actuator through the operation display interface 8. For example, the operation display interface 8 is provided with a start and stop button, or the operation display interface 8 is a touch screen display with various operation buttons, and the user can directly control the operation buttons on the touch screen display.

[0041] The following is a detailed introduction to the various components of the test device for testing the rolling load of the anti-static movable floor provided by the present application.

[0042] The test bench 1 is used to support the guide rail 2 and the fixed beam 5. The test bench 1 may include a planar frame and support legs for supporting the planar frame. The support legs may be adjustable support legs so that the height of the test bench 1 can be adjusted according to operational needs.

[0043] The sliding bracket 3 is used to drive the fixing device 33 and the test plate 7 fixed to the fixing device 33 to reciprocate on the guide rail 2. The sliding bracket 3 is connected to the motor 31, which provides power for the movement of the sliding bracket 3. The specific structure of the sliding bracket 3 is not limited in this application; as long as it can reciprocate on the guide rail, it is sufficient.

[0044] In one specific example, the sliding bracket 3 includes a slideway that cooperates with the two rails of the guide rail 2. The two slideways of the sliding bracket 3 are formed of two oppositely disposed U-shaped channel steels 34. The U-shaped grooves of the two oppositely disposed U-shaped channel steels 34 are respectively sleeved onto the two rails of the guide rail 2, and the U-shaped channel steels 34 can run along the two rails of the guide rail 2. The slideway composed of the two U-shaped channel steels 34 can ensure that the test plate 7 on the fixture 33 does not experience any bumps during operation, thereby ensuring the accuracy of the test results.

[0045] The fixing device 33 is used to fix the test plate 7 during testing. The present application does not limit the structure of the fixing device 33, as long as it can fix the test plate 7. For example, the test plate 7 can be clamped using a clamp.

[0046] In a specific embodiment, if Figure 2 As shown, the fixing device 33 includes at least two parallel I-shaped steel structures, the length direction of the I-shaped steel structure is perpendicular to the length direction of the guide rail 2; one side surface of the I-shaped steel structure is fixedly connected to the sliding bracket 3, so that the grooves of the two adjacent I-shaped steel structures are arranged relative to each other; the spacing between the two adjacent I-shaped steel structures is adapted to the size of the test plate 7, so that the opposite ends of the test plate 7 are clamped in the grooves of the two adjacent I-shaped steel structures.

[0047] Because the I-shaped steel structure itself has two opposing grooves, the grooves of the two spaced-apart I-shaped steel structures are precisely adapted to hold the test plate 7 between them. The fixture 33 formed from the I-shaped steel structure is simple in structure and easily mounts the test plate 7. Furthermore, according to the national standard GB / T36340-2018, "General Specification for Anti-static Raised Floors," three test plates 7 are required for each test. Therefore, the fixture 33 can be formed from four equally spaced I-shaped steel structures.

[0048] Furthermore, the I-shaped steel structure can also serve to connect the two U-shaped channel steels 34 , that is, if the I-shaped steel structure is used to form the fixing device 33 , no other structure is needed to connect the two U-shaped channel steels 34 , and the I-shaped steel structure can serve to connect the two U-shaped channel steels 34 .

[0049] The limit device 21 can be a contact limit switch or a non-contact limit switch, which is not limited in this application. In addition, the limit device 21 can be installed at both ends of the guide rail 2 or at positions opposite to the sliding bracket 3 at both ends of the test bench 1, which is not limited in this application.

[0050] The displacement sensor 32 can be a dial indicator or an XY function recorder, etc., which is not limited in this application. The displacement sensor 32 can be pre-installed on the sliding bracket 3 or installed on the bottom surface of the test plate 7 during the test, which is not limited in this application.

[0051] The fixed beam 5 spans above the test bench 1 and is located in the middle of the length direction of the guide rail (2). It is used to fix the loading device 4 so that the loading device 4 is suspended above the sliding bracket 3. This application does not limit the structure of the fixed beam 5.

[0052] In a specific embodiment, the fixed beam 5 includes two groups of first fixed beams 51 and second fixed beams 52 arranged at intervals, and the structures of the first fixed beams 51 and the second fixed beams 52 are the same; the first fixed beam 51 includes two first vertical beams 511 and a first cross beam 512, and the second fixed beam 52 includes two second vertical beams 521 and a second cross beam 522; the two first vertical beams 511 are respectively located on both sides of the sliding bracket 3 and are vertically fixed to the two ends of the test bench 1, and the top ends of the two first vertical beams 511 are connected to the first cross beam 512; the two second vertical beams 521 are respectively located on both sides of the sliding bracket 3 and are vertically fixed to the two ends of the test bench 1, and the top ends of the two second vertical beams 521 are connected to the second cross beam 522; the first cross beam 512 and the second cross beam 522 are both perpendicular to the length direction of the guide rail 2; the top of the loading device 4 is fixed between the first cross beam 512 and the second cross beam 522, and the axial direction of the rolling wheel 41 is parallel to the first cross beam 512 or the second cross beam 522.

[0053] In the embodiment of the present application, a first fixed beam 51 and a second fixed beam 52 are arranged in parallel and spaced relation to each other to jointly fix the loading device 4, and the loading device 4 is suspended above the sliding bracket 3, thereby ensuring the stability of the loading device 4. More importantly, the stability of the loading device 4 is maintained even when the rolling wheel 41 is in motion, thereby ensuring the consistency of the load applied to the test panel 7 throughout the test.

[0054] In another specific embodiment, in order to ensure the overall stability of the fixed beam 5, a triangular fixing member is provided on the upper side of the fixed beam 5, and a reinforcing member is provided on the lower side of the fixed beam 5. Specifically, Figure 2 and Figure 5 As shown, at least one reinforcement member 53 is connected between the first fixed beam 51 and the second fixed beam 52; the reinforcement member 53 is located on the lower side of the fixed beam 5; the reinforcement member 53 includes two first reinforcement members 531 and one second reinforcement member 532, wherein the two first reinforcement members 531 are respectively used to connect the first vertical beam 511 and the second vertical beam 521 located on the same side of the sliding bracket 3, and the second reinforcement member 532 is vertically connected to the two first reinforcement members 531. Figure 2 As shown, the first reinforcement 531 is used to connect the two vertical beams located on the same side of the sliding bracket 3, the second reinforcement 532 is used to connect the two first reinforcements 531 together, and the reinforcement 53 fixes the two independent first fixed beams 51 and second fixed beams 52 together, ensuring the stability of the lower side of the fixed beam 5.

[0055] The upper side of the first fixing beam 51 is connected to a first triangular fixing member 513, and the upper side of the second fixing beam 52 is connected to a second triangular fixing member 523. Figure 5 As shown, the first triangular fixing member 513 may include two inclined reinforcing ribs, one of which is used to connect the first vertical beam 511 and the first horizontal beam 512. This inclined reinforcing rib, the first vertical beam 511, and the first horizontal beam 512 form a stable triangular structure. The other inclined reinforcing rib is used to connect another first vertical beam 511 and the first horizontal beam 512. This inclined reinforcing rib, the other first vertical beam 511 and the first horizontal beam 512 form another stable triangular structure. The second triangular fixing member 523 is identical to the first triangular fixing member 513 and will not be described again here. The first triangular fixing member 513 and the second triangular fixing member 523 can ensure the stability of the individual first fixed beams 51 and the second fixed beams 52.

[0056] In summary, the cooperation between the reinforcement member 53 , the first triangular fixing member 513 and the second triangular fixing member 523 ensures the overall stability of the fixed beam 5 .

[0057] The loading device 4 is used to apply a load to the test plate 7. The loading device 4 can employ hydraulic, pneumatic, or mechanical loading methods, which are not limited in this application. The top of the loading device 4 is provided with a connector that connects to the fixed beam 5. The bottom of the loading device 4 is connected to a rolling wheel 41. The rolling wheel 41 is connected to a lifting mechanism of the loading device 4. The lifting mechanism of the loading device 4 can drive the rolling wheel 41 to extend and retract in a direction perpendicular to the plane of the guide rail 2.

[0058] In a specific embodiment, if Figure 2 and Figure 6 As shown, the top connector of the loading device 4 is detachably connected to the first crossbeam 512 and the second crossbeam 522. After installation, the loading device 4 is located between the first fixed beam 51 and the second fixed beam 52. The loading device 4 can be adjusted in the lengthwise direction of the first crossbeam 512 and the second crossbeam 522 according to test requirements. This application does not limit the manner in which the top connector of the loading device 4 is detachably connected to the first crossbeam 512 and the second crossbeam 522. For example, a threaded connection can be used.

[0059] It should also be noted that, in order to meet the test standards of the national standard GB / T36340-2018 "General Specification for Anti-static Raised Floors," the test apparatus for testing the rolling load of anti-static raised raised floors in the embodiments of the present application is equipped with at least three sizes of rolling wheels 41. The three sizes of rolling wheels 41 are different. The first size of the rolling wheel 41 has a diameter of 76.2 mm, a wheel width of 46.0 mm, and a rolling crown wrapped with hard rubber or phenolic material with a Shore hardness of 90±5. The second size of the rolling wheel 41 has a diameter of 152 mm, a wheel width of 50.8 mm, and a rolling crown wrapped with polyurethane material with a Shore hardness of 80±5. The third size of the rolling wheel 41 has a diameter of 254 mm, a wheel width of 102 mm, and a rolling crown wrapped with polyurethane material with a Shore hardness of 80±5.

[0060] In summary, the test device for testing the rolling load of the anti-static movable floor provided in the embodiment of the present application, the sliding bracket 3 can run smoothly on the guide rail 2 to ensure the accuracy of the test results; the control device 6 can realize fully automatic testing of the rolling load of the anti-static movable floor based on the data collected by the limit device 21, the pressure sensor and the displacement sensor 32.

[0061] The present application also provides a method for testing the rolling load of an anti-static movable floor. The method is implemented based on the anti-static movable floor rolling load test device described in any of the above embodiments. Figure 7 As shown, the following steps are included:

[0062] Step S1 : Install the test plate 7 on the fixing device 33 , and install a rolling wheel 41 of a corresponding model according to the model of the test plate 7 .

[0063] For example, the test panels 7 can be classified into ultralight, light, standard, heavy, and super heavy types according to their load-bearing types. The second type of rolling wheel 41 can be used to test test panels 7 of all types except the super heavy type, and the third type of rolling wheel 41 can be used to test super heavy type test panels 7.

[0064] In step S2 , the control device 6 controls the rolling wheel 41 to contact the test plate 7 , and controls the loading device 4 to load the test plate to a preset rolling load value.

[0065] The loading device 4 is equipped with a pressure sensor, which is connected to the control device 6. The pressure sensor can transmit collected pressure data to the control device 6 in real time. When the current load value collected by the pressure sensor reaches the preset rolling load value, the control device 6 can control the rolling load applied by the loading device 4 based on the pressure data transmitted by the pressure sensor.

[0066] Step S3: Adjust the displacement value of the displacement sensor 32 to zero.

[0067] The displacement sensor 32 is used to collect in real time the displacement changes of the bottom surface of the test plate 7 located above the displacement sensor 32 during the test, so as to calculate the deflection and residual deformation of the test plate.

[0068] The displacement sensor 32 can also be connected to the control device 6. The control device 6 can receive the displacement data collected by the displacement sensor 32 in real time and can process the displacement data. For example, the control device 6 can calculate the maximum deformation (i.e., deflection) of the bottom surface of the test plate 7 and the residual deformation of the test plate 7 based on the displacement data.

[0069] In step S4 , the control device 6 controls the sliding bracket 3 to drive the test plate 7 to reciprocate on the guide rail 2 .

[0070] After completing steps 1-3 above, the control device 6 starts the motor 31 connected to the sliding bracket 3 and the limiting device 21 , so that the sliding bracket 3 drives the test plate 7 to reciprocate on the guide rail 2 .

[0071] Step S5: The control device 6 receives the data collected by the displacement sensor 32 and the limit device 21 and processes the data.

[0072] Among them, the data collected by the displacement sensor 32 is the displacement change data of the bottom surface of the test plate 7, and the limit device 21 has a counting function. The data it collects is the number of times the sliding bracket 3 reciprocates on the guide rail 2, that is, the number of times the test plate 7 rolls through the rolling wheel 41.

[0073] Step S6: If the maximum displacement value collected by the displacement sensor 32 exceeds the preset displacement value, or the number of cycles collected by the limit device 21 reaches the preset number of cycles, the control device 6 controls the sliding bracket 3 to stop moving; wherein, if the maximum displacement value collected by the displacement sensor 32 exceeds the preset displacement value, the number of cycles collected by the limit device 21 is recorded; if the number of cycles collected by the limit device 21 reaches the preset number of cycles, the maximum displacement value collected by the displacement sensor 32 is recorded.

[0074] The number of cycles mentioned in step 6 above refers to the number of times the sliding bracket 3 reciprocates on the guide rail 2 .
