Description

Technical Field

[0001] The invention relates to the technical field of mechanical load test devices, in particular to a universal mechanical load test connection device for a suspension wire clamp and a connecting plate. Background Art

[0002] Suspension wire clamps and connecting plates in power fittings are important metal components in the power system. Mechanical load test is an important test to measure the mechanical performance indicators of suspension wire clamps and connecting plates. Whether their mechanical load meets the standard is related to the overall safe, stable and reliable operation of the power grid.

[0003] The current standard GB / T2317.1-2008 provides the layout of the mechanical load test for the suspension clamp and the connecting plate. Fig.11 and Fig.12 . Fig.11 The mechanical property test of the mid-hanging wire clamp requires a linear component that matches the wire trough of the hanging wire clamp to be tested. The two ends of the linear component are connected to the lower U-shaped component, and an angle adjustment device is required. The connection method is analyzed and found to be relatively complex, with many corresponding connection accessories. The deformation of the linear component under load will affect the mechanical property test results of the test hanging wire clamp. Fig.12 The mechanical property test of the central connecting plate requires a similar-shaped and hole-positioned central connecting plate component and corresponding connecting accessories. This connection method is also relatively complicated, and the removal of the test piece after the test is cumbersome and labor-intensive.

[0004] The current standard GB / T2317.1-2008 only proposes the above two typical connection methods, but does not give the specific connection process and implementation methods. By comparing the above two connection methods, it is found that the test layout methods of the suspension wire clamp and the connecting plate are completely different, and their respective test layout methods are relatively complicated. This results in the need to continuously replace the auxiliary connecting parts matching the suspension wire clamp and the connecting plate during the alternating inspection of the suspension wire clamp and the connecting plate, which increases the workload of the inspection personnel and reduces work efficiency.

[0005] Therefore, on the basis of meeting the mechanical load test of suspension wire clamps and connecting plates specified in the national standard (GB / T2317.1), providing a universal mechanical load test connection device for suspension wire clamps and connecting plates that can quickly and efficiently perform alternating inspections of the above two types of hardware has become an urgent problem to be solved by technical personnel in this field.

The difference between the mechanical load test of the suspension wire clamp and the mechanical load test of the connecting plate performed using the universal mechanical load test connecting device for the suspension wire clamp and the connecting plate is whether a cross bar 9 is provided, and the two ends of the cross bar 9 are respectively detachably connected to the two third through grooves 8, and the cross bar 9 is easy to disassemble and assemble. In this way, the universal mechanical load test connecting device for the suspension wire clamp and the connecting plate can quickly and efficiently perform alternating inspections of the suspension wire clamp and the connecting plate.

[0036] In this embodiment, the universal mechanical load test connection device for the suspension wire clamp and the connecting plate further includes a connecting plate 13. When the mechanical load test of the suspension wire clamp is performed, the upper portion of the connecting plate 13 is clamped in the first through groove and detachably connected to the first through groove, and the lower portion of the connecting plate 13 is detachably connected to the hanger of the suspension wire clamp 11 to be tested. By providing the connecting plate 13, the top end of the suspension wire clamp is conveniently connected to the first through groove.

[0037] In this embodiment, the universal mechanical load test connection device for the suspension wire clamp and the connecting plate also includes four pins 14. The first through holes 15 for the pins 14 to pass through are arranged on the two side walls opposite to the first through slot, the two side walls opposite to the second through slot 6, and the two side walls opposite to the third through slot 8. The upper part of the connecting plate 13, the bottom end of the U-shaped support plate 7, and the two ends of the crosspiece 9 are all provided with second through holes 16 for the pins 14 to pass through. One second through hole 16 is connected to two first through holes 15, and forms a connecting hole with the two corresponding first through holes 15. One pin 14 is rotatably installed in one connecting hole, and the two ends of the pin 14 are respectively flush with the two ends of the connecting hole. With such an arrangement, the device is easy to disassemble and assemble.

[0038] In this embodiment, the universal mechanical load test connection device for the suspension wire clamp and the connecting plate further includes a top plate assembly, and the first threaded hole 21 and the second threaded hole 22 are symmetrically arranged on both sides of each first through hole 15, and the top plate assembly includes a plate body 17, a first screw 18, a second screw 19 and a third screw 20. The plate body 17 is provided with a first threaded opening, a second threaded opening and a third threaded opening, and the first threaded opening, the second threaded opening and the third threaded opening correspond to the first threaded hole 21, the first through hole 15 and the second threaded hole 22, respectively. The first screw 18 is threadedly connected to the first threaded opening and the first threaded hole 21, the second screw 19 is threadedly connected to the second threaded opening, and the third screw 20 is threadedly connected to the third thread and the second threaded hole 22. Under normal circumstances, the pin is directly pushed out of the connecting hole along one end face by manpower. When it is difficult to remove by manpower, the top plate assembly is used for removal. The specific dismantling process takes the removal of the pin shaft between the first through groove and the connecting plate 13 as an example. First, the plate body 17 is fixed to the outer wall of the first connecting block 2 by the first screw 18 and the third screw 20, and then the third screw 20 is rotated. While the third screw 20 is rotated, the pin shaft can be pushed to gradually disengage from the connecting hole.

[0039] In this embodiment, specifically, one end of the first connecting column 1 is threadedly connected to the first connecting block 2, one end of the second connecting column 3 is threadedly connected to the second connecting block 4, one of the end of the first connecting column 1 away from the first connecting block 2 and the end of the second connecting column 3 away from the second connecting block 4 is threadedly connected to the upper clamp of the universal testing machine, and the other is threadedly connected to the lower clamp of the universal testing machine.

[0040] In this embodiment, considering the stress stability of the connecting plate 13 in the test and the size of the opening of the hanging bracket of the suspension clamp 11 to be tested, the upper thickness of the connecting plate 13 is greater than the lower thickness of the connecting plate 13 .

[0041] In this embodiment, specifically, the lower portion of the connecting plate 13 is connected to the bracket by bolts.

[0042] In this embodiment, specifically, the cross-sections of the first through groove, the second through groove 6 and the third through groove 8 perpendicular to their respective length directions are all U-shaped.

[0043] In this embodiment, specifically, the first connecting pillar 1 and the second connecting pillar 3 are both cylindrical structures.

[0044] In addition, in order to make the groove wall of the groove 10 fit with the groove wall of the wire groove, the groove line 24 of the groove of the crosspiece 9 and the groove line 25 of the wire groove of the suspended wire clamp 11 to be tested need to be consistent in shape and size. Fig.10 As shown, in this embodiment, specifically, the inner groove line 24 of the groove of the crosspiece 9 and the inner groove line 25 of the wire groove of the suspension wire clamp to be measured are both composed of straight line segments and arc segments. When the crosspiece 9 is processed, the tangent angle at the point where the inner groove line 24 of the groove of the crosspiece 9 coincides with the arc end point of the inner groove line of the suspension wire clamp is determined according to the total length of the suspension wire clamp to be measured, the length of the inner groove line straight line segment, and the radius of the arc segment, and then the forming condition of the inner groove line 24 of the groove of the crosspiece 9 is determined. The tangent angle calculation formula is as follows:

[0045] a=arcsin{(L1-L2) / R}

[0046] Wherein: a is the tangent angle at the point where the inner groove line 24 of the groove of the crosspiece 9 coincides with the arc end point of the inner groove line 25 of the suspension line clamp; L1 is 1 / 2 of the hull length of the suspension line clamp; L2 is 1 / 2 of the length of the straight section of the inner groove line of the suspension line clamp; R is the radius of the arc section of the inner groove line 25 of the suspension line clamp.

[0047] Specifically, in this embodiment, the tangent angle a at the point where the inner groove line 24 of the groove of the cross piece 9 and the arc end point of the inner groove line 25 of the suspension wire clamp coincide with each other is not less than 25°.

[0048] It should be noted that the inner groove shape and size of the groove 10 of the cross bar 9 of the universal mechanical load test connection device for the suspension wire clamp and the connecting plate provided in this embodiment are fixed, so the universal mechanical load test connection device for the suspension wire clamp and the connecting plate provided in this embodiment does not need to be equipped with an angle adjustment device. Fig.11 The function of the middle angle adjustment device 26 is to adjust the shape of the linear member 23 so that the shape of the linear member 23 meets the requirements of the outlet angle of the suspension clamp 11 to be tested; the top, bottom, upper part and lower part mentioned above are all the universal mechanical load test connection device for the suspension clamp and the connecting plate according to Figure 1 The arrangement shown refers to the arrangement shown.

[0049] The present specification uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
