[0020] Example 1: Figure 1 、 Figure 2 and Figure 3 The strength detection device for angle steel or channel steel shown in the figure includes a bottom plate 10, a PLC controller 11 and a pressure sensor 29.

[0021] A set of vertical support plates 16 are symmetrically provided at both ends of the bottom plate 10.

[0022] The upper end surfaces of the vertical support plates 16 are respectively connected with horizontal fixing plates 23.

[0023] A set of vertical support plates 16 are symmetrically provided with horizontal support parts 18 on the inner walls of the middle opposite sides.

[0024] A hydraulic cylinder slot 24 is provided in the symmetrical center line of the horizontal fixed plate 23.

[0025] A hydraulic cylinder mounting bracket 25 is provided on the horizontal fixing plate 23 and above the hydraulic cylinder slot 24.

[0026] A hydraulic cylinder 26 is provided on the hydraulic cylinder mounting frame 25.

[0027] One end face of the hydraulic cylinder 26 is provided with a transition pressure block 27.

[0028] One side of the transition pressing block 27 is symmetrically provided with vertical ear plates 30.

[0029] A circular groove 28 is provided on one side of the transition pressing block 27 and between the vertical lugs 30.

[0030] Vertical strip grooves 31 are symmetrically arranged in the vertical ear plate 30.

[0031] The vertical strip grooves 31 are respectively provided with horizontal screws 35.

[0032] The horizontal screw 35 is provided with a limit nut 33.

[0033] The opposite side of the horizontal screw 35 is provided with a movable pressure block 32.

[0034] The movable pressure bearing block 32 is provided with a circular boss 34 and a limit slot 36 on both sides.

[0035] The pressure sensor 29 is disposed in the circular groove 28 . The pressure sensor 29 is connected to the PLC controller 11 via wire or wireless communication. The horizontal screw 35 slides vertically in the vertical strip groove 31 .

[0036] The two ends of the angle steel or channel steel (blank or finished product) to be tested are clamped horizontally on the horizontal support part 18, and the hydraulic cylinder 26 is started to press down. The hydraulic cylinder 26 links the transition pressure block 27, the vertical ear plate 30, the horizontal screw 35, the limit nut 33, the movable pressure block 32, and the circular boss 34 to move downward synchronously until the limit slot 36 is aligned with the surface of the angle steel or channel steel. At this time, the hydraulic cylinder 26 continues to press down, and the horizontal screw 35 slides upward in the vertical strip groove 31. At this time, the circular boss 34 is embedded in the circular groove 28 and contacts the pressure sensor 29;

[0037] At this time, the hydraulic cylinder 26 continues to press down, and the pressure sensor 29 transmits the pressure data value to the PLC controller 11; when the angle steel or channel steel is deformed or broken, the PLC controller 11 records the final value and controls the hydraulic cylinder 26 to reset, thus completing the maximum pressure resistance (pressure bearing) test of the angle steel or channel steel.

[0038] Embodiment 2: Based on the embodiment 1, a strength detection device for angle steel or channel steel further includes a bottom plate screw groove 12 provided at an edge of an end surface of one end of the bottom plate 10, a vertical screw 13 provided in the bottom plate screw groove 12, a vertical screw nut 15 provided at one end of the vertical screw 13, and a warning strobe light 14 provided at the other end of the vertical screw 13;

[0039] Among them, the warning strobe light 14 is connected to the PLC controller 11. When the angle steel or channel steel is deformed or broken, the pressure data value transmitted to the PLC controller 11 by the pressure sensor 29 will fluctuate. At this time, the PLC controller 11 controls the warning strobe light 14 to flash to remind the inspection personnel and control the hydraulic cylinder 26 to stop to complete the safe inspection.

[0040] Example 3: Based on Example 1 or Example 2, Figure 4 and Figure 5The strength detection device for angle steel or channel steel shown in the figure also includes transverse through holes 20 symmetrically arranged in the middle of a group of vertical support plates 16, and fixing seats 17 respectively arranged on one side of the transverse support part 18, and fixing seat screw grooves 19 respectively arranged on one side of the fixing seat 17, and bolts 21 for fixing and assembling the vertical support plates 16 and the fixing seats 17 through the transverse through holes 20 and the fixing seat screw grooves 19. The above structure realizes the detachable design of the transverse support part 18, which is convenient for replacing the fixing seat 17 and the transverse support part 18 to match the pressure-bearing test of the angle steel or channel steel, and is also convenient for replacement after long-term use and wear.

[0041] Example 4: Based on Example 1, Example 2 or Example 3, the strength detection device for angle steel or channel steel also includes a reinforcing support portion 22 symmetrically arranged on the inner wall of the middle portion of a group of vertical support plates 16 and in contact with the connecting surface of the horizontal support portion 18 and the fixing seat 17. The above-mentioned design structure increases the pressure-bearing strength of the horizontal support portion 18 and the fixing seat 17, thereby completing a safe, stable and accurate compressive strength test of the angle steel or channel steel.

[0042] In addition, preferably, the horizontal support portion 18 and the limit slot 36 are respectively set to a right-angle structure or a U-shaped structure to provide horizontal support therefor, so as to achieve the matching pressure detection requirements of the angle steel or channel steel; the diameter of the circular groove 28 is larger than the diameter of the circular boss 34. During detection, the circular boss 34 is embedded in the circular groove 28 to achieve stable contact with the pressure sensor 29, thereby meeting the precise detection requirements.

[0043] The structural principle or working principle of the strength detection device for angle steel or channel steel of this structure is as follows:

[0044] Please review Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 :

[0045] First, place the angle steel or channel steel to be tested for pressure horizontally on the cross support 18;

[0046] Then, the hydraulic cylinder 26 is controlled to press downward, and the hydraulic cylinder 26 links the transition pressure block 27, the vertical ear plate 30, the horizontal screw 35, the limit nut 33, the movable pressure block 32, and the circular boss 34 to move downward synchronously until the limit slot 36 is aligned with the surface of the angle steel or channel steel. At this time, the hydraulic cylinder 26 continues to press downward, and the horizontal screw 35 slides upward in the vertical strip groove 31. At this time, the circular boss 34 is embedded in the circular groove 28 and contacts the pressure sensor 29.

[0047] Finally, the hydraulic cylinder 26 is controlled to continue to press downward, and the pressure sensor 29 transmits the pressure data value to the PLC controller 11.

[0048] When the angle steel or channel steel is deformed or broken, the PLC controller 11 records the final value and controls the hydraulic cylinder 26 to reset, thereby completing the maximum pressure resistance (bearing pressure) test of the angle steel or channel steel.

[0049] The PLC controller 11, hydraulic cylinder 26 and pressure sensor 29 of the strength detection device for angle steel or channel steel of this structure are all conventional components or equipment and will not be described in detail in this application.
