Description

Technical Field

[0001] The utility model relates to the technical field of electric power detection equipment, in particular to a suspension wire clamp failure load adjustable test device. Background Art

[0002] Suspension clamps are an important part of overhead transmission lines. They are mainly used to suspend conductors and optical cables on insulator strings or towers. They generally include components such as hulls, rotating shafts, and pressure strips (including fastening screws). Under normal operating conditions, they mainly bear vertical loads from conductors and optical cables. If the suspension clamp is of unqualified quality and cannot withstand the vertical load within the specified range and breaks, it will cause the conductor to break, causing circuit accidents and even casualties, with serious consequences and far-reaching impacts. Therefore, before the suspension clamp is put into use, it will be subjected to a destructive load test to determine whether its mechanical strength meets the requirements.

[0003] At present, during the test of the suspension clamp on the market, it is necessary to use the test fixture to carry out the destructive load test on the suspension clamp. The steel strand is often used as the load-bearing body of the experiment. The steel strand is installed in the wire trough of the suspension clamp, and the two ends of the wire trough are fixed on the two fixed brackets of the test fixture. After the connection is completed, the test fixture is connected to the fixed end of the tensile machine, and the suspension clamp is connected to the moving end of the tensile machine, so as to carry out the destructive load test on the suspension clamp. In order to better simulate the operation of the wire installed on the suspension clamp, the test requires that the lead-out angle of the force-adding wire should be maintained at about 1 / 2 of the designed lead-out angle α of the suspension clamp. However, since the installation and connection positions of the test fixture and the steel strand are fixed, the lead-out angle of the force-adding wire cannot be reliably and accurately controlled. With the loading of the test force, it is easy to cause the lead-out angle to be too large or too small, resulting in inaccurate test. Therefore, the applied force needs to be adjusted constantly during the experiment, and the debugging process is relatively cumbersome, which affects the normal progress of the test.

In the adjustable destructive load test device for the suspension wire clamp provided by the utility model, a sliding connection is realized between the two adjusting plates through the cooperation of the sliding hole and the sliding rod, and the length distance between the two adjusting plates connected to the two wiring baffles is changed by adjustment. Due to the change in the length distance of the adjusting plates, the two wiring baffles will be driven to rotate, thereby achieving the purpose of adjusting the rotation angle of the two wiring baffles, wherein, after the two adjusting plates are adjusted, a fixed connection is achieved through a locking structure, and the locking structure preferably adopts a nut fastening method to lock the connection position of the two adjusting plates, specifically, a threaded structure is provided on the sliding rod, that is, the sliding rod is equivalent to a screw structure, so that the locking nut is movably connected to the sliding rod through the threaded structure, and when the locking nut is tightened and fixed, the two adjusting plates are fastened together, thereby playing a role of locking the relative position of the two adjusting plates to avoid relative displacement between the two, with good installation stability and convenient adjustment operation.

[0022] 3. In the test device for adjustable destructive load of the suspension wire clamp provided by the utility model, two groups of wiring baffles and two groups of wiring baffles are symmetrically arranged about the central axis of the pull plate structure.

[0023] 4. In the adjustable breaking load test device for the suspension wire clamp provided by the utility model, both ends of the steel strand are fixedly connected to the mouths of two sets of wiring baffles through two square-headed crimping tubes, thereby firmly locking the two ends of the steel strand on the two sets of wiring baffles. The mouth has a notch, which just makes one end of the upper crimping tube abut against the notch of the mouth to form a limit fit, so as to prevent the square-headed crimping tube from shaking or shifting during the test, thereby ensuring the installation position stability of the square-headed crimping tube and the steel strand.

[0035] Example

[0036] The present embodiment is described in detail below with reference to the accompanying drawings:

[0037] This embodiment provides Figure 1-5 The shown device is a test device for adjustable breaking load of a suspension wire clamp, comprising: two groups of wiring baffles 1, a pull plate structure 4, a steel strand 5 and an adjustment mechanism, wherein the two groups of wiring baffles 1 are connected to the two ends of a support plate 2 by relative rotation; the steel strand 5 is passed through the wire groove of the suspension wire clamp, and its two ends extending out of the wire groove are respectively fastened to the heads of the two groups of wiring baffles 1 through a fixing structure; the pull plate structure 4 is respectively connected to the tails of the two groups of wiring baffles 1 through two groups of connecting plates 3; the adjustment mechanism comprises at least two adjustment plates 6 slidably connected between the two groups of wiring baffles 1, and a locking structure 7 arranged between the two adjustment plates 6 for keeping the relative positions of the two fixed, the two adjustment plates 6 are respectively connected to the two groups of wiring baffles 1 at one end extending backwards, and when the two adjustment plates 6 slide relative to each other, the two groups of wiring baffles 1 are driven to rotate a certain angle with the two ends of the support plate 2 as the rotation center. During the mechanical strength tensile test of the suspension wire clamp, it is necessary to control the outlet angle of the steel strand 5 to about 1 / 2 of the designed outlet angle of the suspension wire clamp through the adjustment mechanism to ensure that the force is basically consistent with that during the actual operation of the suspension wire clamp. Then, the pulling plate structure 4 of the test device is connected to the moving section of the tensile testing machine, and the suspension wire clamp is connected to the fixed end of the tensile testing machine. Finally, the tensile testing machine is started to carry out the destructive load test of the suspension wire clamp.

[0038] In the above embodiment, the adjustment mechanism includes two adjustment plates 6 slidably connected between the two groups of wiring baffles 1. When the two adjustment plates 6 slide relative to each other to adjust the length distance, the two groups of wiring baffles 1 will be driven to rotate a certain angle with the two ends of the support plate 2 as the rotation center. The two ends of the steel strand 5 are fixedly connected to the two groups of wiring baffles 1, thereby realizing the angle adjustment of the outlet angle of the steel strand 5, and the two adjustment plates 6 keep the relative positions of the two locked by the locking structure 7 after completing the position adjustment to avoid further displacement. The adjustable test device of the technical solution can control the outlet angle within the range specified by the standard through the adjustment mechanism. It is suitable for suspension wire clamps of different specifications, lengths and different outlet angles, and has strong versatility. By using steel strands to simulate the mechanical strength of the suspension wire clamp, the outlet angle of the steel strand can be adjusted to about 1 / 2 of the designed outlet angle α of the suspension wire clamp during the test. This is closer to the actual use of the suspension wire clamp, ensuring the smooth progress of the test, and can improve the accuracy and reliability of the suspension wire clamp failure load test results, which is convenient for controlling the strength performance of the suspension wire clamp product.

[0039] The following is combined with Figure 1-4 The specific setting method of the adjustment mechanism is explained in detail:

[0040] The two adjustment plates 6 are connected and arranged parallel to the support plate 2. One of the adjustment plates 6 is provided with a sliding hole 61 extending along its length direction, and the other adjustment plate 6 is correspondingly provided with at least one sliding member slidably connected to the sliding hole 61. It is further preferably arranged that the sliding member is a sliding rod 62 arranged on the other adjustment plate 6 and passing through the sliding hole 61. The two adjustment plates 6 are slidably connected through the cooperation of the sliding hole 61 and the sliding rod 62. The length distance between the two adjustment plates 6 connected to the two wiring baffles 1 is changed by adjustment. Due to the change in the length distance of the adjustment plates, the two wiring baffles 1 will be driven to rotate, thereby achieving the purpose of adjusting the rotation angle of the two wiring baffles to meet the requirements of the outlet angle α during the test.

[0041] According to the two adjustment plates 6, after the adjustment is completed, the two adjustment plates 6 are fixedly connected by the locking structure 7, as a preferred embodiment, Figure 1-3As shown, the locking structure 7 includes a threaded structure arranged on the slide bar 62, and a locking nut 71 connected to the slide bar 62 through the threaded structure, and the locking nut 71 locks the two adjustment plates 6 to keep the relative position fixed when tightened. From the above structure, it can be seen that the locking structure 7 preferably uses a nut tightening method to lock the connection position of the two adjustment plates 6, and the slide bar 62 with a threaded structure is equivalent to a screw structure, so that the locking nut 71 can be movably connected to the slide bar 62 through the threaded structure, and when the locking nut 71 is tightened and fixed, the two adjustment plates 6 are fastened together, thereby playing a role of locking the relative position of the two adjustment plates to prevent the two from being relatively displaced again; and when adjustment is required, just loosen the locking nut, and the two adjustment plates can be slid to adjust the length distance, and the adjustment operation is convenient.

[0042] As an alternative to the above-mentioned adjustment mechanism, refer to Figure 4 , the sliding member can also be a slider 63 arranged on the other adjusting plate 6 and passed through the sliding hole 61, the slider 63 is in an L-shaped structure or a T-shaped structure, the locking structure 7 includes a plurality of locking holes 73 arranged along the movement path of the slider 63 and arranged on one of the adjusting plates 6 and located on one side of the sliding hole 61, and a locking member 72 passing through the slider 63 and fixedly connected in the locking hole 73, the locking member 72 can preferably be a pin structure or a screw structure, and the locking hole corresponds to a pin hole or a screw hole. With this structural setting, the locking member 72 plays a limiting locking role on the slider 63 of the L-shaped or T-shaped structure, thereby limiting the displacement and sliding of the two adjusting plates 6. Such a design can also achieve the relative position locking between the two adjusting plates. Those skilled in the art can make a choice of the specific manner of the sliding member and the locking structure according to the above description, and will not be described one by one here.

[0043] In this embodiment, combined with Figure 1 and Figure 5 As shown, the two groups of wiring baffles 1 are provided with a concave mouth portion 13 on the side facing away from the support plate 2, and the fixing structure includes two square head crimping tubes 8 crimped on both ends of the steel strand 5, and the two square head crimping tubes 8 are respectively connected to the mouth portions 13 of the two groups of wiring baffles 1, so that the two ends of the steel strand 5 are firmly locked on the two groups of wiring baffles 1. Figure 5 It can be seen that the mouth portion 13 has a notch, which just allows one end of the square crimping tube 8 to abut against the notch of the mouth portion 13 to form a limit fit, so as to prevent the square crimping tube from shaking or shifting during the test, thereby ensuring the installation position stability of the square crimping tube 8 and the steel strand 5. The steel strand is used to test the mechanical strength of the suspension wire clamp, which avoids stress concentration and is closer to the actual application of the suspension wire clamp.

[0044] As a preferred embodiment, each set of wiring baffles 1 includes two baffles 11 arranged opposite to each other, and a limit bolt 12 passing through the head position of the two baffles 11, so that the steel strand 5 is matched with and abutted against the limit screw when passing through the two baffles 11. This structural setting plays the role of connecting the two baffles 11 through the limit bolt 12. In addition, when the two ends of the steel strand 5 are tightened by force, the steel strand 5 passing through the two baffles 11 is matched with and abutted against the limit screw, ensuring that the steel strand can only be deformed at the position of the limit bolt 12, thereby limiting the steel strand through the limit bolt.

[0045] Combination Figure 1-2 As shown, the two groups of wiring baffles 1 and the two groups of wiring baffles 1 are symmetrically arranged about the central axis of the pull plate structure 4. As a specific structural arrangement, the two ends of the support plate 2 are fixedly connected to the middle position of the two groups of wiring baffles 1 by the first bolt structure 91, and the two groups of connecting plates 3, the two groups of wiring baffles 1 and the two adjustment plates 6 are respectively connected by the two groups of second bolt structures 92, so that the two adjustment plates 6 are respectively connected between the two baffles 11 of the two groups of wiring baffles 1 by the second bolt structure 92, wherein the top of the pull plate structure 4 is provided with a T-shaped extension for connecting the two groups of the connecting plates 3, and each group of connecting plates 3 includes two strip plates arranged opposite to each other, and one end of the two strip plates is connected to the tail position of the two baffles 11 by the second bolt structure 92. The other ends of the two strip plates are connected to the T-shaped extension part through the third bolt structure 93. With this structural setting, when the mechanical strength test of the suspension clamp is carried out with the help of the test device, the steel strand 5 is installed in the wire groove of the suspension clamp to simulate the running conductor, and the outlet angle of the steel strand passing through the wire groove of the suspension clamp is adjusted by the adjustment mechanism, and the outlet angle is controlled within the range specified by the standard. Finally, the suspension clamp is subjected to a destructive load test by a tensile testing machine. The two sets of wiring baffles can achieve a stable connection with the pulling plate structure through the two sets of connecting plates to improve the strength of the test device, and can also evenly distribute the load of the tensile testing machine to the suspension clamp. The test device with this symmetrical structure setting can ensure that the suspension clamp is subjected to uniform force during the test and ensure the effect of the tensile test.

[0046] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
