[0042] Figure 1 It is a front view of a test device for a support rod provided in an embodiment of the present disclosure. Figure 2 FIG. 1 is a top view of a test device for a support rod provided in an embodiment of the present disclosure. Figure 1 , 2 As shown, the test device includes: a first fixing seat 10, a second fixing seat 20, a support rod 30 to be tested, a force-applying assembly 40 and a collection assembly 50. The first fixing seat 10 and the second fixing seat 20 are arranged at intervals, and the force-applying assembly 40 is located on the first fixing seat 10.

[0043] like Figure 1 , 2 As shown, the acquisition component 50 includes: a strain gauge 51 and a pressure sensor 52, the strain gauge 51 is located on the surface of the support rod 30 to be tested, and the force-applying component 40 includes: a bearing plate 41, a force-applying member 42 and a supporting ear plate 43, the force-applying member 42, the pressure sensor 52 and the supporting ear plate 43 are all located on the bearing plate 41, the force-applying member 42 and the supporting ear plate 43 are respectively located on the opposite end surfaces of the pressure sensor 52, the force-applying member 42 is used to apply a force perpendicular to the end surface of the pressure sensor 52 to the pressure sensor 52, one end of the support rod 30 to be tested is hinged to the supporting ear plate 43, and the other end of the support rod 30 to be tested is connected to the second fixing seat 20.

[0044] The bearing plate 41 is configured to be detachably mounted at different positions of the first fixing seat 10 , so that the force applied by the force applying member 42 to the pressure sensor 52 has different angles with the axial direction of the support rod 30 to be tested.

[0045] The test device of the support rod provided in the embodiment of the present disclosure includes a first fixed seat 10, a second fixed seat 20, a support rod 30 to be tested, a force-applying assembly 40 and a collection assembly 50. The force-applying assembly 40 is arranged on the first fixed seat 10, and the strain gauge 51 of the collection assembly 50 is installed on the surface of the support rod 30 to be tested, and is used to detect the deformation amount of the support rod 30 to be tested. One end of the support rod 30 to be tested is hinged to the support ear plate 43 of the force-applying assembly 40, and the other end of the support rod 30 to be tested is connected to the second fixed seat 20. When a test is required, a force is applied to the pressure sensor 52 through the force-applying member 42, so that the force is transmitted to the support ear plate 43 on the other side of the pressure sensor 52, and the support rod 30 to be tested connected to the support ear plate 43.

[0046] Meanwhile, the carrying plate 41 is detachably connected to the first fixing seat 10 . Figure 3 is a top view of another support rod test device provided by an embodiment of the present disclosure, such as Figure 2 , 3 As shown, by adjusting the position of the bearing plate 41 installed on the first fixing seat 10, the force applied by the force-applying member 42 to the pressure sensor 52 has different angles with the axial direction of the support rod 30 to be tested, thereby simulating the loads applied in various directions borne by the support rod. In this way, the loads borne in different directions by the support rod under various working conditions can be fully simulated, thereby effectively evaluating the bearing capacity of the support rod and ensuring that the support rod can be used safely after being installed on the pillar body.

[0047] Alternatively, if Figure 2 As shown, the surface of the first fixing seat 10 for mounting the bearing plate 41 has a plurality of connecting screw holes 11 , and the plurality of connecting screw holes 11 are evenly arranged circumferentially with the center of the inner hole of the supporting ear plate 43 as the center.

[0048] like Figure 2 As shown, the surface of the bearing plate 41 has a connecting through hole 410 , and the bearing plate 41 is connected to different connecting screw holes 11 by bolts passing through the connecting through hole 410 .

[0049] In the above implementation, the supporting plate 41 is moved to different positions of the first fixed seat 10 so that the connecting through hole 410 of the supporting plate 41 is opposite to the connecting screw hole 11 at different positions, and then bolts are passed through the connecting through hole 410 and the connecting screw hole 11 to fix the supporting plate 41 on the first fixed seat 10, thereby achieving the purpose of controlling the supporting plate 41 to rotate to different angles, so that the force applied by the force-applying member 42 to the pressure sensor 52 has different angles with the axial direction of the support rod 30 to be tested, and can simulate the loads applied in various directions to the support rod.

[0050] Optionally, the central angle of the arc passing through the centers of two adjacent connecting screw holes 11 is 10° to 50°.

[0051] For example, Figure 2 As shown, the central angle of the arc passing through the centers of two adjacent connecting screw holes 11 is 30°.

[0052] Exemplarily, the central angle of the arc passing through the centers of two adjacent connecting screw holes is 45°.

[0053] By setting the central angle of the arc passing through the centers of two adjacent connecting screw holes 11 within the above range, it is possible to avoid the spacing angle between adjacent connecting screw holes 11 being too large, so that the force applying member 42 can only apply force to the bearing rod in a small number of different directions.

[0054] Alternatively, if Figure 1 , 2 As shown, the force-applying assembly 40 further includes: a fixing clamp 44 and a connector 45 . The fixing clamp 44 clamps the pressure sensor 52 , and both end surfaces of the pressure sensor 52 are located outside the fixing clamp 44 .

[0055] Exemplarily, the fixing clamp 44 can be a Huff clamp. When installing the pressure sensor 52, the pressure sensor 52 is placed in a circular arc plate of the Huff clamp, and then covered with another circular arc plate to form a circular hole that clamps the pressure sensor 52, thereby fixing the pressure sensor 52 in the fixing clamp 44.

[0056] Among them, an arc plate of the fixing clamp 44 can be fixed on the bearing plate 41 by bolts to prevent the pressure sensor 52 from loosening.

[0057] like Figure 1 , 2 As shown, one end face of the pressure sensor 52 contacts the force applying member 42 , and the other end face of the pressure sensor 52 is threadedly connected to one end of a connector 45 , and the other end of the connector 45 is connected to the support ear plate 43 , and the fixing clamp 44 is located on the plate surface of the bearing plate 41 .

[0058] Exemplarily, one end of the connector 45 has an external thread, the end face of the pressure sensor 52 opposite to the connector 45 has a screw hole, and the end of the connector 45 with the external thread is threadedly connected to the screw hole of the pressure sensor 52 to fix the connector 45 on the pressure sensor 52.

[0059] Exemplarily, the support ear plate 43 includes a connecting plate and two ear plates spaced parallel to the connecting plate. The other end of the connector 45 is plate-shaped, and the other end of the connector 45 fits the connecting plate, and the other end of the connector 45 and the connecting plate can be fixedly connected by bolts. In this way, the force received by the pressure sensor 52 can be transmitted to the support rod 30 to be tested through the connector 45 and the support ear plate 43, so as to realize the load test.

[0060] Alternatively, if Figure 1 , 2 As shown, the force-applying assembly 40 also includes a baffle 46 and a pad 47. One side edge of the baffle 46 is located on the plate surface of the supporting plate 41. The baffle 46 and the fixing clamp 44 are arranged at intervals. The force-applying member 42 is located between the baffle 46 and the fixing clamp 44, and the pad 47 is clamped between the force-applying member 42 and the baffle 46.

[0061] Exemplarily, the force applying member 42 may be a jack and a hydraulic cylinder. For example, the force applying member 42 is a 20T thin jack.

[0062] When the jack or hydraulic cylinder applies force to the pressure sensor 52, it pushes the piston rod to extend and retract, so that the piston rod can move against the pressure sensor 52. If the piston rod cannot contact the pressure sensor 52 even after being extended and retracted to the maximum extent, a cushion block 47 can be provided between the force applying member 42 and the baffle 46 to ensure that the pressure is applied to the pressure sensor 52.

[0063] Exemplarily, the pad 47 may include a plurality of pads 47 of different thicknesses, so that when it is necessary to increase the force applied by the force-applying member 42 , a pad 47 with a large thickness may be used to shorten the distance between the force-applying member 42 and the pressure sensor 52 , thereby allowing the piston rod of the force-applying member 42 to apply a greater force to the pressure sensor 52 .

[0064] Exemplarily, the pad 47 may be a rubber block.

[0065] Alternatively, if Figure 1 As shown, the force applying assembly 40 further includes a support frame 48 , which is located on the bearing plate 41 and between the baffle 46 and the fixing clamp 44 , and the force applying member 42 is located on the support frame 48 .

[0066] By providing a support frame 48 below the force applying member 42 to support the force applying member 42 , the force applying member 42 is prevented from sliding down from between the pressure sensor 52 and the baffle 46 due to gravity, thereby improving the reliability of the force applying assembly 40 .

[0067] Figure 4 FIG. 4 is a schematic diagram of another force-applying assembly 40 provided in an embodiment of the present disclosure. Figure 4 As shown, the support ear plate 43 is fixed to the connector 45 by bolts. The force applying assembly 40 further comprises an oil filling bag 49 , which is sandwiched between the support ear plate 43 and the connector 45 , and has an oil filling nozzle 491 .

[0068] like Figure 4As shown, an oil injection channel 431 is provided in the support ear plate 43, a first end of the oil injection channel 431 is located on the hole wall of the inner hole of the support ear plate 43, a second end of the oil injection channel 431 is located on the plate surface opposite to the support ear plate 43 and the connecting head 45, and the second end of the oil injection channel 431 is connected to the oil injection nozzle 491.

[0069] In the above implementation, an oil filling bag 49 is provided between the connector 45 and the support ear plate 43, and lubricating oil is injected into the oil filling bag 49. When the force exerted by the force applying member 42 on the pressure sensor 52 increases, the force exerted by the connector 45 on the oil filling bag 49 also increases, which will squeeze the lubricating oil in the oil filling bag 49 into the oil filling channel 431 from the oil filling nozzle 491, and flow into the hole wall of the inner hole of the support ear plate 43 through the oil filling channel 431, so that the lubricating oil can form an oil film between the support ear plate 43 and the pin, reduce the friction resistance between the support ear plate 43 and the pin, and reduce the damage to the support ear plate 43 or the pin caused by excessive pressure between the support ear plate 43 and the pin due to increased load.

[0070] Exemplarily, the surface of the connector 45 has a mounting groove, and the oil filling bag 49 can be placed in the mounting groove so that only a portion of the oil filling bag 49 is located outside the mounting groove and in contact with the support ear plate 43. This can prevent the oil filling bag 49 from being damaged by excessive extrusion pressure.

[0071] Alternatively, if Figure 4 As shown, an oil delivery channel 451 is provided in the connecting head 45, a first end of the oil delivery channel 451 is located on the side wall of the connecting head 45, a second end of the oil delivery channel 451 is located on the end surface of the connecting head 45 opposite to the supporting ear plate 43, and the oil filling bag 49 also has an oil delivery nozzle 492, which is connected to the second end of the oil delivery channel 451.

[0072] By providing an oil delivery channel 451 on the connector 45, when the lubricating oil in the oil filling bag 49 is missing, the lubricating oil can be replenished in time to ensure that the hinged position of the support ear plate 43 and the support rod 30 to be tested is fully lubricated to avoid easy damage due to excessive pressure.

[0073] Alternatively, if Figure 1 As shown, the test device also includes: a first lifting assembly 61 and a second lifting assembly 62, the first lifting assembly 61 is located on one side of the first fixed seat 10, and the first lifting assembly 61 and the force-applying assembly 40 are respectively located on opposite sides of the first fixed seat 10, the second lifting assembly 62 is located on one side of the second fixed seat 20, and the second lifting assembly 62 and the other end of the support rod 30 to be tested are respectively located on opposite sides of the second fixed seat 20.

[0074] By setting a first lifting assembly 61 on one side of the first fixing seat 10, the height of the first fixing seat 10 can be adjusted, and by setting a second lifting assembly 62 on one side of the second fixing seat 20, the height of the second fixing seat 20 can be adjusted. When it is necessary to simulate the support rod under extreme working conditions, when the force borne by the support rod is not along the axial direction of the support rod, the two lifting assemblies can be controlled to make the heights of the first fixing seat 10 and the second fixing seat 20 different to achieve the working condition where the force borne by the support rod is not along the axial direction of the support rod. Therefore, the test device can more comprehensively simulate the actual working conditions of the support rod, effectively evaluate the support rod, and ensure that the support rod can be used safely and reliably.

[0075] Optionally, the first lifting assembly 61 and the second lifting assembly 62 both include a mounting block 601 and a lifting rod 602 , one end of the lifting rod 602 is connected to the mounting block 601 , and the other end of the lifting rod 602 is connected to the first fixing seat 10 or the second fixing seat 20 .

[0076] Exemplarily, a plurality of mounting blocks 601 and a plurality of lifting rods 602 may be provided on one side of the first fixing seat 10 , and the plurality of lifting rods 602 may be arranged at intervals, so that the board surface of the first fixing seat 10 may be tilted by controlling the lifting heights of different lifting rods 602 .

[0077] For example, a plurality of mounting blocks 601 and a plurality of lifting rods 602 may be provided on one side of the second fixing seat 20, and the plurality of lifting rods 602 are arranged at intervals, so that the plate surface of the second fixing seat 20 can be tilted by controlling the lifting heights of different lifting rods 602, so as to simulate the load that the support rod can bear when there is torque at both ends of the support rod. Therefore, the test device can more comprehensively simulate the actual working conditions of the support rod, effectively evaluate the support rod, and ensure that the support rod can be used safely and reliably.

[0078] As an example, three mounting blocks and three lifting rods may be provided on one side of the first fixing seat 10, and the connecting line of the distribution positions of the three mounting blocks is an equilateral triangle.

[0079] As an example, three mounting blocks and three lifting rods may be provided on one side of the second fixing seat 20, and the connecting line of the distribution positions of the three mounting blocks is an equilateral triangle.

[0080] Exemplarily, the lifting rod may be a telescopic gas rod.

[0081] The test device for the support rod provided in the embodiment of the present disclosure can first conduct a small ballast pre-test when conducting a load test on the support rod to verify whether the test device is assembled in place and whether the pressure sensor 52 and the strain gauge 51 collect data normally, and ensure that all links are normal before starting the ballast test of the support rod. Control the jack to slowly load the force on the support rod, observe the pressure data and strain data of the support rod through the data acquisition system, and check whether the appearance of the support rod is intact under different pressures, whether there is deformation, and whether the pin shaft hole is deformed or burned.

[0082] The test device for the support rod provided in the embodiment of the present disclosure can verify whether the support rod can work normally under extreme working conditions such as wind loads of different intensities and directions, waves, and different degrees of tilt and sway; the bearing plate 41 can change different directions through the connecting screw holes 11 arranged at intervals of 30° on the first fixing seat 10, one end of the support rod is fixed and limited by the second fixing seat 20, and the other end of the support rod is limited by the fixing clamp 44, and the pressure sensor 52 is squeezed when the piston rod of the jack is extended to transfer the pressure to the support rod, and the direction of the force can be adjusted by adjusting the position of the bearing plate 41 on the first fixing seat 10, thereby simulating the support rod being subjected to wind loads of different directions and different degrees of tilt and sway; the pad 47 between the jack and the baffle 46 can adjust the distance between the pressure sensor 52 and the baffle 46, so as to adjust the pressure range of the support rod.

[0083] The above does not limit the present disclosure in any form.
