[0002] The posture testing device in the related technology is usually used to simulate various tilting postures of the powertrain to test the performance of the powertrain. Specifically, the posture testing device in the related technology usually includes a pitch mechanism, which is provided with multiple groups of support columns.

[0041] In the description of the present invention, "first feature" or "second feature" may include one or more of the features.

[0042] In the description of the present invention, "plurality" means two or more than two, and "several" means one or more.

[0043] like Figure 1-Figure 8 As shown, the posture testing device 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0044] The posture testing device 1 according to the embodiment of the present invention includes a fixing seat 100 , a plurality of rotating mechanisms and a driving control module 400 .

[0045] One of the multiple rotating mechanisms is connected to the fixed seat 100 and the other is suitable for fixing the power assembly. The multiple rotating mechanisms are connected in sequence and each rotating mechanism includes a rotating table. The rotating table of each rotating mechanism can rotate along its rotation axis respectively. The projections of the rotation axes of the multiple rotating tables in the plane where the fixed seat 100 is located intersect. The drive control module 400 is respectively connected to the multiple rotating mechanisms to selectively drive at least one of the multiple rotating tables to rotate.

[0046] The driving component of the driving control module 400 in the embodiment of the present invention may be a hydraulic pump station 410. The powertrain may be an engine, or a hybrid powertrain of an engine and an electric motor, or a dual-motor powertrain.

[0047] Among them, the angular rotation range of the rotating table of each rotating mechanism can be less than the preset angle, for example, 50°, that is, when a rotating mechanism is in the initial state, the rotating table of the rotating mechanism can remain horizontal, and the angles of the rotating table rotating clockwise and counterclockwise around its rotation axis do not exceed half of the preset angle. It can be understood that when the vehicle is driving under normal working conditions, the tilt angle of the vehicle will not be too large. By limiting the rotation angle of the rotating table, the posture of the powertrain under normal working conditions can be simulated to facilitate testing the performance of the powertrain under normal working conditions, and the stability of the test of the posture test device 1 can be ensured.

[0048] Among them, the drive control module 400 is respectively connected to multiple rotating mechanisms to selectively drive at least one of the multiple rotating tables to rotate, which means that the drive control module 400 can drive multiple rotating tables of the multiple rotating mechanisms to rotate simultaneously to adjust the tilt angle of the powertrain in multiple directions, or the drive adjustment module can only drive part of the rotating mechanisms to operate, that is, only drive part of the multiple rotating tables to rotate, and then only adjust the tilt angle of the powertrain in one direction or part of the directions to realize the posture simulation of the powertrain under various working conditions.

[0049] According to the posture testing device 1 of the embodiment of the present invention, by connecting one of the multiple rotating mechanisms to the fixed seat 100 and the other fixing the power assembly, for example, the multiple rotating mechanisms can be stacked in the up and down directions, the bottom rotating mechanism can be fixed on the fixed seat 100, the multiple rotating mechanisms are arranged upward in sequence, and each rotating mechanism is fixed on another rotating mechanism below it, and the rotating table of the rotating mechanism located at the top is used to fix the power assembly.

[0050] In this way, when the drive control module 400 drives the rotating platform of a rotating mechanism to rotate, the rotating platform can drive all the rotating mechanisms above to rotate together, and then the driving mechanism can drive the power assembly to rotate relative to the fixed seat 100 to adjust the tilt posture of the power assembly, so as to facilitate testing the performance of the power assembly under different tilt postures. In addition, by setting up multiple rotating mechanisms, multiple rotating mechanisms can respectively drive the rotation angle of the power assembly in different directions, so as to facilitate adjusting the tilt angle of the power assembly in multiple directions, which is conducive to improving the accuracy of the posture simulation of the power assembly, and thus can improve the accuracy of the test.

[0051] In addition, compared with the pitch mechanism in the traditional technology that adjusts the angle of the powertrain through the support column, the embodiment of the present invention utilizes the rotation of multiple rotating tables to adjust the tilt angle of the powertrain. The rotation structure of the rotating table is relatively simple, which is conducive to simplifying the structure of the attitude testing device 1, and the angle adjustment of the powertrain is simpler and easier. Moreover, the response of the powertrain to rotate by rotating the rotating table around the rotation axis can be faster, thereby improving the response speed of the powertrain rotation adjustment.

[0052] Moreover, compared with the supporting column structure of the pitch mechanism in traditional technology, the height of the rotating table can be set lower, which is not only conducive to reducing the overall height of the posture testing device 1, so that the stability of the posture testing device 1 is higher, thereby improving the safety of the posture testing device 1 during testing, but also convenient for fixing the powertrain to the posture testing device 1, and convenient for workers to stand on the posture adjustment equipment to perform assembly and connect wiring harnesses, etc., with higher operational safety.

[0053] As such, the posture testing device 1 according to the embodiment of the present invention has the advantages of simple structure, low height, higher safety and fast response.

[0054] In some specific embodiments of the present invention, Figure 1-Figure 5 As shown, the plurality of rotating mechanisms include at least a first rotating mechanism 200 and a second rotating mechanism 300 .

[0055] The first rotating mechanism 200 is disposed on the fixed seat 100, and the first rotating mechanism 200 includes a first rotating table 210, and the first rotating table 210 can rotate relative to the fixed seat 100 along a first axis. The second rotating mechanism 300 is disposed on the first rotating table 210, and the second rotating mechanism 300 includes a second rotating table 310, and the second rotating table 310 can rotate relative to the first rotating table 210 along a second axis, and the projections of the second axis and the first axis in the plane where the fixed seat 100 is located intersect.

[0056] The driving control module 400 is connected to the first rotating mechanism 200 and the second rotating mechanism 300 respectively to drive the first rotating platform 210 and / or the second rotating platform 310 to rotate.

[0057] For example, the drive control module 400 may only drive the first rotating table 210 to rotate along the first axis, or the drive control module 400 may only drive the second rotating table 310 to rotate along the second axis, or the drive control module 400 may simultaneously drive the first rotating table 210 to rotate around the first axis and drive the second rotating table 310 to rotate around the second axis.

[0058] Moreover, the projections of the second axis and the first axis in the plane where the fixing seat 100 is located intersect, so that the first rotating table 210 and the second rotating table 310 can drive the power assembly to rotate in different directions, and then adjust the rotation angle of the power assembly in different directions, which can better simulate the tilting posture of the power assembly and help improve the accuracy of the test.

[0059] Furthermore, if Figure 1 As shown, the projections of the first axis and the second axis in the plane where the fixed seat 100 is located are perpendicular to each other, so that the first axis can simulate the front-to-back direction of the powertrain, and the second axis can simulate the left-to-right direction of the powertrain. The first rotating table 210 and the second rotating table 310 can drive the powertrain to simulate the angle tilt in the front-to-back direction and the left-to-right direction, which can not only simplify the structure of the rotating mechanism, but also improve the posture simulation angle of the posture testing device 1 for the powertrain, and the test accuracy is higher.

[0060] In some specific embodiments of the present invention, Figure 1-Figure 5 As shown, the first rotating mechanism 200 further includes a first actuator 220 and a first bearing assembly 230 , and the second rotating mechanism 300 further includes a second actuator 320 and a second bearing assembly 330 .

[0061] The first actuator 220 is connected to the drive control module 400 , fixed to the fixed seat 100 and transmission-connected to one side of the first rotating platform 210 , the first bearing assembly 230 is fixed to the fixed seat 100 , and the other side of the first rotating platform 210 is rotatably connected to the first bearing assembly 230 .

[0062] The second actuator 320 is connected to the drive control module 400 , the second actuator 320 is fixed to the first rotating table 210 and is transmission-connected to one side of the second rotating table 310 , the second bearing assembly 330 is fixed to the first rotating table 210 , and the other side of the second rotating table 310 is rotatably connected to the second bearing assembly 330 .

[0063] Specifically, the first actuator 220 can be connected to the rotating shaft through a transition flange, and the rotating shaft is connected to one side of the first rotating platform 210, and the other side of the first rotating platform 210 can be rotatably fixed to the first bearing assembly 230 through another rotating shaft, so that both ends of the first rotating platform 210 can be stably supported, and the driving control module 400 can drive the first rotating platform 210 to rotate around the first axis through the first actuator 220. In addition, in this arrangement, the rotating shaft does not need to pass through the first rotating platform 210, thereby avoiding position interference between the rotating shaft and the second avoidance groove 212 described below, and the structural arrangement is more reasonable.

[0064] In addition, the second actuator 320 can be connected to one end of the rotating shaft through a transition flange, the rotating shaft is connected to the second rotating table 310, and the rotating shaft can pass from one side of the second rotating table 310 to the other side of the second rotating table 310, so that the other end of the rotating shaft can be rotatably fixed to the second bearing assembly 330, both ends of the second rotating table 310 can be stably supported, and the drive control module 400 can drive the second rotating table 310 to rotate around the second axis through the second actuator 320.

[0065] Furthermore, in this embodiment, if Figure 1 As shown, the driving component of the drive control module 400 can be a hydraulic pump station 410, and the first actuator 220 and the second actuator 320 can both be spiral swing cylinders. By using the hydraulic pump station 410 as the drive and the spiral swing cylinder as the actuator, a very large torque output can be achieved in a very small space, and the structure is compact and beautiful.

[0066] In some specific embodiments of the present invention, Figure 2 As shown, the posture testing device 1 further includes a first angle detector 211 .

[0067] The first angle detector 211 is disposed on the first rotating platform 210 and / or the first bearing assembly 230 to detect the rotation angle of the first rotating platform 210 , and the first angle detector 211 is electrically connected to the driving control module 400 .

[0068] Among them, the first angle detector 211 may include an angle encoder and an angle encoder bracket. The angle encoder can be fixed on the rotating shaft of the first rotating table 210, and the angle encoder bracket can be fixed on the first bearing assembly 230. In this way, when the first rotating table 210 drives the rotating shaft to rotate relative to the first bearing assembly 230, the angle encoder can rotate relative to the angle encoder bracket, and then the rotation angle of the first rotating table 210 can be detected, and the rotation angle of the first rotating table 210 can be fed back to the driving control module 400, so that the driving control module 400 can adjust the rotation angle and rotation speed of the first rotating table 210 driven by the first actuator 220 according to the rotation angle signal of the first rotating table 210. For example, the first rotating table 210 can be controlled by the first actuator 220 to rotate to a specific angle and hover, or the first rotating table 210 can be controlled by the first actuator 220 to rotate back and forth.

[0069] In addition, if Figure 3 and Figure 4 As shown, the posture testing device 1 also includes a second angle detector 311, which is arranged on the second rotating table 310 and / or the second bearing assembly 330 to detect the rotation angle of the second rotating table 310, and the second angle detector 311 is electrically connected to the drive control module 400.

[0070] Similarly, the second angle detector 311 may also include an angle encoder and an angle encoder bracket. The angle encoder may be fixed on the rotating shaft of the second rotating table 310, and the angle encoder bracket may be fixed on the second bearing assembly 330. In this way, when the second rotating table 310 drives the rotating shaft to rotate relative to the second bearing assembly 330, the angle encoder may rotate relative to the angle encoder bracket, thereby detecting the rotation angle of the second rotating table 310, and feeding back the rotation angle of the second rotating table 310 to the drive control module 400, so that the drive control module 400 can adjust the rotation angle and rotation speed of the second rotating table 310 driven by the second actuator 320 according to the rotation angle signal of the second rotating table 310. For example, the second rotating table 310 may be controlled by the second actuator 320 to rotate to a specific angle and hover, or the second rotating table 310 may be controlled by the second actuator 320 to rotate back and forth.

[0071] In some specific embodiments of the present invention, Figure 1 As shown, the driving control module 400 includes a hydraulic pump station 410 , a first servo unit 420 and a second servo unit 430 .

[0072] The first servo unit 420 is arranged on the fixed seat 100 and connected between the hydraulic pump station 410 and the first actuator 220, the first angle detector 211 is electrically connected to the first servo unit 420, the second servo unit 430 is arranged on the first rotating table 210 and connected between the hydraulic pump station 410 and the second actuator 320, and the second angle detector 311 is electrically connected to the second servo unit 430.

[0073] The first servo unit 420 and the second servo unit 430 may both be servo motors, and the first servo unit 420 may be fixed to the fixing base 100 via a fixing bracket 440 , and the second servo unit 430 may be fixed to the first rotating platform 210 via a fixing bracket 440 .

[0074] In this way, the hydraulic pump station 410 can first control the first actuator 220 to drive the first rotate table 210 to rotate through the first servo unit 420, and the first angle detector 211 will then feed back the detected rotation angle of the first rotate table 210 to the first servo unit 420 in real time. The first servo unit 420 will then control the first actuator 220 in real time according to the signal feedback from the first angle detector 211, and thus can control the rotation angle and rotation speed of the first rotate table 210, thereby achieving precise control of the tilt angle of the powertrain.

[0075] Similarly, the hydraulic pump station 410 can first control the second actuator 320 to drive the second rotating table 310 to rotate through the second servo unit 430, and the second angle detector 311 will then feed back the detected rotation angle of the second rotating table 310 to the second servo unit 430 in real time. The second servo unit 430 will then control the second actuator 320 in real time based on the signal feedback from the second angle detector 311, and thus can control the rotation angle and rotation speed of the second rotating table 310, thereby achieving precise control of the tilt angle of the powertrain.

[0076] In some specific embodiments of the present invention, Figure 4 As shown, the posture testing device 1 further includes a first sensor (not shown in the figure) and a second sensor 321 .

[0077] The first sensor is provided on the first actuator 220 to limit the rotation angle of the first rotating platform 210, and the second sensor 321 is provided on the second actuator 320 to limit the rotation angle of the second rotating platform 310. In this way, the rotation angle of the first actuator 220 and the rotation angle of the second actuator 320 can be safely limited to prevent the first actuator 220 and the second actuator 320 from overshooting.

[0078] In some specific embodiments of the present invention, Figure 1 As shown, the posture testing device 1 further includes a plurality of first limiting brackets 500 and a plurality of second limiting brackets 600 .

[0079] The first limiting bracket 500 is movably supported between the first rotating table 210 and the fixed seat 100, and multiple first limiting brackets 500 are arranged on opposite sides of the first axis to limit the rotation of the first rotating table 210 relative to the fixed seat 100. The second limiting bracket 600 is movably supported between the second rotating table 310 and the first rotating table 210, and multiple second limiting brackets 600 are arranged on opposite sides of the second axis to limit the rotation of the first rotating table 210 relative to the second rotating table 310.

[0080] In this way, when the first position-limiting bracket 500 is fixed between the first rotating table 210 and the fixing base 100, the first position-limiting bracket 500 can support the first rotating table 210 so that the first rotating table 210 does not rotate relative to the fixing base 100. And, when the second position-limiting bracket 600 is fixed between the second rotating table 310 and the first rotating table 210, the first position-limiting bracket 500 can support the second rotating table 310 so that the second rotating table 310 does not rotate relative to the first rotating table 210.

[0081] Therefore, the first limit bracket 500 and the second limit bracket 600 can be used to lock and limit the first rotating table 210 and the second rotating table 310, so that personnel can stand on the second rotating table 310 to install auxiliary wiring harnesses or connectors, etc., effectively preventing the first rotating table 210 or the second rotating table 310 from rotating, thereby ensuring the absolute safety of personnel, and when it is necessary to drive the power adjustment device to rotate through the posture testing device 1, the first limit bracket 500 and the second limit bracket 600 can be removed to avoid the first rotating table 210 or the second rotating table 310 from squeezing the limit brackets and causing damage.

[0082] In addition, it should be noted that the drive control device can be a hydraulic pump station 410, and the hydraulic pump station 410 can perform a hydraulic lock to lock the first actuator 220 and the second actuator 320. By adding a first limit bracket 500 and a second limit bracket 600, the first limit bracket 500 and the second limit bracket 600 can be used as a second safety barrier to further ensure the safety of personnel.

[0083] Furthermore, if Figure 2 and Figure 5 As shown, the posture testing device 1 further includes a third sensor 510 and a fourth sensor 610 .

[0084] The third sensor 510 is arranged on the first limit bracket 500 and is electrically connected to the drive control module 400 to detect the relative position of the first limit bracket 500 and the first rotating table 210. The fourth sensor 610 is arranged on the second limit bracket 600 and is electrically connected to the drive control module 400 to detect the relative position of the second limit bracket 600 and the second rotating table 310.

[0085] In this way, the third sensor 510 can detect whether the first limit bracket 500 is between the first rotating table 210 and the fixed seat 100. When the posture testing device 1 needs to operate, the signal of the third sensor 510 can be obtained. If the third sensor 510 feedbacks that the first limit bracket 500 is still between the first rotating table 210 and the fixed seat 100, the posture testing device 1 will not be operated. If the third sensor 510 feedbacks that the first limit bracket 500 has been removed from between the first rotating table 210 and the fixed seat 100, the posture testing device 1 can be operated, which more effectively prevents the first rotating table 210 from squeezing the first limit bracket 500 and causing damage.

[0086] Similarly, the fourth sensor 610 can detect whether the second limit bracket 600 is between the second rotating table 310 and the first rotating table 210. When the posture testing device 1 needs to be operated, the signal of the fourth sensor 610 can be obtained. If the fourth sensor 610 feedbacks that the second limit bracket 600 is still between the second rotating table 310 and the first rotating table 210, the posture testing device 1 will not be operated. If the fourth sensor 610 feedbacks that the second limit bracket 600 has been removed from between the second rotating table 310 and the first rotating table 210, the posture testing device 1 can be operated, which more effectively prevents the second rotating table 310 from squeezing the second limit bracket 600 and causing damage.

[0087] In some specific embodiments of the present invention, Figure 5 As shown, the posture testing device 1 further includes a first buffer block 110 , which is disposed on a side of the fixing seat 100 facing the first rotating platform 210 and / or a side of the first rotating platform 210 facing the fixing seat 100 .

[0088] For example, the first buffer block 110 can be arranged on the side of the fixed seat 100 facing the first rotating table 210, or the first buffer block 110 can be arranged on the side of the first rotating table 210 facing the fixed seat 100, or the first buffer block 110 can be arranged on both the side of the fixed seat 100 facing the first rotating table 210 and the side of the first rotating table 210 facing the fixed seat 100.

[0089] By setting the first buffer block 110, when the first rotating table 210 rotates to the extreme position, or the posture testing device 1 fails and causes the first rotating table 210 to rotate and collide with the fixed seat 100, the first buffer block 110 can be used to buffer and reduce vibration between the first rotating table 210 and the fixed seat 100, thereby reducing the impact force between the first rotating table 210 and the fixed seat 100 and avoiding collision damage between the first rotating table 210 and the fixed seat 100.

[0090] Among them, there can be multiple first buffer blocks 110, and the multiple first buffer blocks 110 are arranged in a direction perpendicular to the first axis, so that when the first rotating table 210 rotates clockwise or counterclockwise to the extreme position, the first buffer blocks 110 can be used to buffer and reduce vibration of the first rotating table 210 and the fixed seat 100.

[0091] In addition, if Figure 2 and Figure 6 As shown, the posture testing device 1 further includes a second buffer block 240 , which is disposed on a side of the first rotating platform 210 facing the second rotating platform 310 and / or a side of the second rotating platform 310 facing the first rotating platform 210 .

[0092] For example, the second buffer block 240 can be arranged on the side of the first rotating table 210 facing the second rotating table 310, or the second buffer block 240 can be arranged on the side of the second rotating table 310 facing the first rotating table 210, or the second buffer block 240 can be arranged on both the side of the first rotating table 210 facing the second rotating table 310 and the side of the second rotating table 310 facing the first rotating table 210.

[0093] By setting the second buffer block 240, when the second rotating table 310 rotates to the extreme position, or the posture testing device 1 fails and causes the second rotating table 310 to rotate and collide with the first rotating table 210, the second buffer block 240 can be used to buffer and reduce vibration between the second rotating table 310 and the first rotating table 210, thereby reducing the impact force between the second rotating table 310 and the first rotating table 210 and avoiding collision damage between the second rotating table 310 and the first rotating table 210.

[0094] Among them, there can be multiple second buffer blocks 240, and the multiple second buffer blocks 240 are arranged in a direction perpendicular to the second axis, so that when the second rotating table 310 rotates clockwise or counterclockwise to the extreme position, the second buffer blocks 240 can be used to buffer and reduce vibration of the second rotating table 310 and the first rotating table 210.

[0095] In some specific embodiments of the present invention, Figure 5 As shown, the fixing seat 100 is provided with a first avoidance groove 120 to avoid the first rotating platform 210 when the first rotating platform 210 rotates.

[0096] With such an arrangement, the distance between the first rotating table 210 and the fixed seat 100 can be shorter, and when the first rotating table 210 rotates, one side of the first rotating table 210 can be rotated into the first avoidance groove 120, thereby avoiding position interference between the first rotating table 210 and the fixed seat 100, so as to facilitate the rotation of the first rotating table 210, and the height of the first rotating table 210 can be lowered, which is beneficial to reduce the overall height of the posture testing device 1, and further improve the stability of the posture testing device 1.

[0097] Furthermore, if Figure 1 , Figure 2 and Figure 6 As shown, the first rotating platform 210 is provided with a second avoiding groove 212 to avoid the second rotating platform 310 when the second rotating platform 310 rotates.

[0098] With such an arrangement, the distance between the second rotating table 310 and the first rotating table 210 can be closer, and when the second rotating table 310 rotates, one side of the second rotating table 310 can be rotated into the second avoidance groove 212, thereby avoiding position interference between the second rotating table 310 and the first rotating table 210, so as to facilitate the rotation of the second rotating table 310, and the height of the second rotating table 310 can be lowered, which is beneficial to reduce the overall height of the posture testing device 1, and further improve the stability of the posture testing device 1.

[0099] Furthermore, there are multiple first avoidance grooves 120, and the multiple first avoidance grooves 120 are arranged on two opposite sides of the first axis; and / or there are multiple second avoidance grooves 212, and the multiple second avoidance grooves 212 are arranged on two opposite sides of the second axis.

[0100] In this way, when the first rotating platform 210 rotates clockwise or counterclockwise, the side of the first rotating platform 210 close to the fixed seat 100 can be rotated into the first avoidance groove 120, which more effectively avoids the position interference between the first rotating platform 210 and the fixed seat 100. And when the second rotating platform 310 rotates clockwise or counterclockwise, the side of the second rotating platform 310 close to the first rotating platform 210 can be rotated into the second avoidance groove 212, which more effectively avoids the position interference between the second rotating platform 310 and the first rotating platform 210, and the structural setting is more reasonable.

[0101] In some specific embodiments of the present invention, Figure 1 , Figure 3 and Figure 4 As shown, the second rotating mechanism 300 is used to fix the power assembly, and the second rotating platform 310 includes a skeleton plate 312 , a mounting plate 313 and a plurality of mounting brackets 315 .

[0103] That is to say, part of the first connecting holes 317 on the skeleton plate 312 can be connected to part of the connecting holes on the mounting plate 313 through the first fastener to ensure the connection reliability between the skeleton plate 312 and the mounting plate 313, and another part of the first connecting holes 317 on the skeleton plate 312 and another part of the second connecting holes 314 on the mounting part can be used to connect with the third connecting holes 316 of the mounting bracket 315 to ensure the stable connection between the mounting bracket 315 and the mounting plate 313.

[0104] Moreover, with such arrangement, the mounting bracket 315 can be connected and fixed with different first connecting holes 317 and second connecting holes 314, so that when the powertrain specifications are different, the positions of multiple mounting brackets 315 can be adjusted to ensure the reliability of the fixation of the powertrain on the second rotating table 310.

[0105] In addition, it should be noted that the third connecting hole 316 can be constructed as a through hole and the second connecting hole 314 can be constructed as a threaded hole, the second fastener can be passed through the third connecting hole 316 and the second connecting hole 314, and the second fastener can be only screwed to the third connecting hole 316; or, the third connecting hole 316 and the second connecting hole 314 can be constructed as a through hole and the first connecting hole 317 can be constructed as a threaded hole, the second fastener can be passed through the third connecting hole 316, the second connecting hole 314 and the first connecting hole 317, and the second fastener can be only screwed to the first connecting hole 317.

[0106] In addition, by disposing the second rotating platform 310 on the fixing plate and the mounting plate 313, the mounting bracket 315 and the mounting plate 313 can be pre-connected together, and then hoisted onto the frame plate 312 to connect the mounting plate 313 and the frame plate 312. Of course, in some embodiments, the mounting plate 313 and the frame plate 312 can also be constructed as an integral part.

[0107] In some specific embodiments of the present invention, Figure 1 and Figure 5 As shown, the fixing seat 100 includes a seat body 130 , a plurality of reinforcing beams 140 , a plurality of first supporting seats 150 and a plurality of second supporting seats 160 .

[0109] The first support seat 150 and the second support seat 160 can be connected and fixed to the concrete floor by using expansion bolts.
