[0002] As a key load-bearing material in the fields of high-altitude operation of electric power engineering, fire rescue and special transportation, the mechanical strength of the insulation rope is directly related to the safety of personnel and equipment. Static load tension test is a core quality inspection link for testing the rated working load, breaking strength and safety margin of the insulation rope, and has irreplaceable importance for ensuring operation safety, evaluating product life and verifying process stability.

[0003] At present, when the long-size (100m-300m) insulation rope is tested for static load, the following defects mainly exist: the traditional tension machine needs to apply traction along the axial direction of the sample, and the test of the super-long rope requires the equipment to have a super-long stroke and space matched therewith, which leads to high construction cost and most indoor sites cannot meet the requirement of super-long span. Therefore, the existing technology adopts a segmented test method to avoid the space problem, and the long insulation rope is tested by segmentally clamping the long insulation rope by a small tension testing machine. This test method needs to repeatedly adjust the clamping position of the insulation rope, which is not only low in efficiency, but also the method may cause local crushing, broken strands or internal injury of the insulation rope if the clamping is applied at the middle section of the rope body, and the test data may have a large deviation from the actual tension data of the insulation rope, which cannot guarantee the test precision.

DETAILED DESCRIPTION

[0025] The following will be described in detail in combination with the accompanying drawings. Figure 1 - the accompanying drawings Figure 8 The application will be further described in detail.

[0026] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 8 , an insulating rope static load tension testing machine, which is used for static load tension test of long-size insulating rope 8 over 100 meters. The testing machine comprises a test tank 1 which is open upward and fixed on the ground, inner edge plates 2 which are welded on the inner walls of the left and right sides of the test tank 1 along the length direction, two groups of pulley mechanisms 3 which are arranged between the two inner edge plates 2, a traction mechanism one 4 which is arranged between the front side of the test tank 1 and the pulley mechanism 3 sliding on the inner edge plate 2, and a traction mechanism two 5 which is arranged on the left side of the test tank 1.

[0027] In specific work, through the two groups of pulley mechanisms 3 in the test tank 1, a long insulating rope 8 can be naturally bent and reversed into multiple sections without affecting the tension, which can be pulled and moved by the traction mechanism one 4 to move the pulley mechanism 3 unlocked on the front side, and the insulating rope 8 is tested by multiple simultaneous tension; the two groups of pulley mechanisms 3 can also be fixed in the test tank 1 without moving, one end of the insulating rope 8 is fixed on one of the pulley mechanisms 3, and after the insulating rope 8 is continuously reversed and segmented through the two groups of pulley mechanisms 3, the traction mechanism two 5 is pulled and pulled to test the tension of both ends of the whole insulating rope 8, and the condition of the whole insulating rope 8 under tension is tested.

[0028] Referring to Figure 1 , Figure 3 and Figure 4 , in order to reduce the floor space required for long size insulating rope 8 tension test without affecting the force of insulating rope 8, the pulley mechanism 3 provided in the test tank 1 includes a base plate 31, the base plate 31 on one group of pulley mechanisms 3 is fixed on the inner side plate 2 by bolts, the base plate 31 on the other group of pulley mechanisms 3 is slidably arranged on the inner side plate 2 by the sliding block 9, and the base plate 31 is provided with multiple fixed pulleys 33 with adjustable spacing by the connecting assembly 32.

[0029] In specific work, one end of the insulating rope 8 is fixed on one of the rightmost fixed pulleys 33 on the back side, and then the insulating rope 8 is sequentially sleeved on different fixed pulleys 33, so that the originally long size insulating rope 8 can be placed in the test tank 1 without affecting the tension, and the tension transmission of the insulating rope 8 will not be affected.

[0030] It should be particularly pointed out that the fixed pulley 33 in the present scheme adopts a low-rolling-resistance high-precision bearing, and the friction of the fixed pulley 33 rotating is much lower than the tension of the insulating rope 8 tested in the present scheme, so the rotating friction of the fixed pulley 33 is negligible for the data of the present scheme.

[0031] Referring to Figure 1 , Figure 3 and Figure 4 , the upper side of the inner side plate 2 is provided with a slide 6 along the length direction, the sliding block 9 is slidably arranged in the corresponding slide 6, and the bottom inner wall of the slide 6 near the front side is provided with a threaded positioning hole, and the sliding block 9 is provided with a limiting bolt 7, one end of the limiting bolt 7 is threadedly connected with the corresponding threaded positioning hole.

[0032] One of the pulley mechanisms 3 can be unlocked, moved and closed to the rear pulley mechanism 3 along the two inner side plates 2 during the winding of the insulating rope 8, facilitating the winding of the insulating rope 8, and then resetting and locking the pulley mechanism 3. When needed, the locking of the front pulley mechanism 3 can also be unlocked, and connected with the traction mechanism 4, and the front pulley mechanism 3 is moved away from the rear pulley mechanism 3 by the traction mechanism 4 to perform the multi-segment tension test of a single insulating rope 8.

[0033] Referring to Figure 4 and Figure 5 , in order to facilitate the test of insulating ropes 8 of different lengths, the connecting assembly 32 includes a fixed shaft fixedly arranged on the upper side of the base plate 31 close to the right side edge, a fixed beam 321 is rotatably arranged on the fixed shaft, a plurality of U-shaped sleeves 322 are slidably arranged on the fixed beam 321, a fixed pulley 33 is rotatably arranged in the corresponding U-shaped sleeve 322, and a length-adjustable limiting telescopic rod 323 is arranged on the upper side of the U-shaped sleeve 322. The adjacent limiting telescopic rods 323 in the same row along the length direction of the fixed beam 321 abut each other, a supporting locking seat 324 is fixedly arranged on the upper side of the base plate 31, and the side of the fixed beam 321 away from the fixed shaft is detachably fixedly arranged on the supporting locking seat 324.

[0034] Referring to Figures 4-7 , the connecting assembly 32 further includes a limiting seat one 325 fixedly arranged on the upper side of the fixed beam 321 close to the side of the fixed shaft, a sliding hole is formed in the upper side of the fixed beam 321 extending along the length direction thereof, an adjusting screw 326 is rotatably arranged in the sliding hole, one end of the adjusting screw 326 is fixedly connected with an adjusting knob embedded in the fixed beam 321, a sliding seat 327 is threadedly connected with the adjusting screw 326, and a limiting seat two 328 is slidably inserted into the sliding seat 327. The limiting telescopic rod 323 includes a fixed rod fixedly arranged on the upper side of the U-shaped sleeve 322, and a movable rod threadedly connected with one end of the fixed rod. When the U-shaped sleeve 322 is installed on the fixed beam 321, the limiting seat two 328 can be detached from the sliding seat 327, after all the U-shaped sleeves 322 are installed on the fixed beam 321 and adjusted, the limiting seat two 328 is inserted into the sliding seat 327, and then the staff adjusts the position of the limiting seat two 328 on the sliding seat 327 by rotating the adjusting knob to make the adjusting screw 326 rotate, and the limiting seat two 328 abuts against the leftmost movable rod on the fixed beam 321. Thus, all the U-shaped sleeves 322 on the fixed beam 321 are positioned between the corresponding limiting seat one 325 and limiting seat two 328 and cannot slide.

[0035] In specific work, the fixed beam 321 can be rotated to open relative to the base plate 31, as Figure 6, the U-shaped sliding sleeve one 322 can be slidably sleeved on the fixed beam 321, one end of the fixed rod in the rightmost limiting telescopic rod 323 is in active contact with the limiting seat one 325, one end of the active rod in the rightmost limiting telescopic rod 323 is in active contact with the fixed rod in the same row of the left limiting telescopic rod 323, the active rod in the leftmost limiting telescopic rod 323 is in active contact with the limiting seat two 328, and the length of each limiting telescopic rod 323 is adjusted to be consistent, so as to control the distance between the adjacent two U-shaped sliding sleeves one 322, thereby controlling the distance between the adjacent two fixed pulleys 33, and ensuring that each segment of the insulating rope 8 except the first and last two segments is uniformly distributed. When the insulating rope 8 is longer or shorter, the number of fixed pulleys 33 on the fixed beam 321 can be increased or decreased to meet the test needs.

[0036] Referring to Figure 5 and Figure 6 , the upper side of the supporting locking seat 324 is provided with a clamping groove, one side of the fixed beam 321 is movably embedded in the corresponding clamping groove, and the supporting locking seat 324 is further provided with a locking bolt 329, one end of the locking bolt 329 is threadedly connected with the fixed beam 321. The fixed beam 321 is locked by the locking bolt 329.

[0037] Referring to Figure 1 and Figure 5 , the traction mechanism one 4 comprises a hydraulic rod one 41 fixedly arranged on the front side of the test tank 1, and a base plate 31 slidably arranged on the inner edge plate 2. The lower side of the base plate 31 is fixedly provided with a butt joint block 42, the butt joint block 42 is provided with a butt joint hole, the telescopic end of the hydraulic rod one 41 is fixedly connected with a butt joint head 43 matched with the butt joint hole, and the butt joint head 43 is movably inserted into the butt joint hole and fixed by a fixing assembly 44. The fixing assembly 44 comprises a fixing bolt and a fixing nut, the butt joint block 42 is provided with a left-right penetrating through hole one, and the corresponding position of the butt joint head 43 is provided with a through hole two, one end of the fixing bolt is movably inserted through the through hole one and the through hole two and is threadedly connected with the fixing nut.

[0038] In specific work, the sliding block 9 below the front base plate 31 is unlocked, the butt joint head 43 is inserted into the butt joint hole by the extension of the hydraulic rod one 41, and then the butt joint head 43 is fixed with the base plate 31 by the fixing bolt and the fixing nut. Then the hydraulic rod one 41 can be retracted, the fixed pulley 33 on the front base plate 31 is pulled away from the fixed pulley 33 on the rear base plate 31, so that the single insulating rope 8 is divided into multiple sections and the tension test is carried out at the same time.

[0039] Referring to Figure 1 and Figure 4The traction mechanism two 5 includes a hydraulic rod two 51 fixedly arranged on the left side of the test tank 1, the telescopic end of the hydraulic rod two 51 is fixedly connected with a traction seat 52, the upper side of the traction seat 52 is fixedly arranged with a U-shaped sleeve two 53, the U-shaped sleeve two 53 is rotatably connected with a traction wheel 54, and the traction wheel 54 is at the same height as the fixed pulley 33.

[0040] In specific work, a strip-shaped hole for the insulating rope 8 to pass through is arranged on the left side wall of the test tank 1. The two pulley mechanisms 3 are fixed in the specified position and do not move, one end of the insulating rope 8 is fixed on the rightmost fixed pulley 33 in the rear pulley mechanism 3, then the other end of the insulating rope 8 passes through the strip-shaped hole on the side wall of the test tank 1 and is fixedly connected with the traction wheel 54 after sequentially and staggeringly passing through all the fixed pulleys 33. Then the hydraulic rod two 51 is retracted, and one end of the insulating rope 8 is slowly pulled. Due to the reversing effect of the fixed pulley 33, the force of each segment of the whole insulating rope 8 is uniform, the pulling force is consistent with the traction force of the hydraulic rod two 51, one end of the insulating rope 8 is subjected to the pulling force and the whole insulating rope 8 is subjected to the force, and the two ends of the whole insulating rope 8 are subjected to the pressure test pulling force.

[0041] It should be particularly pointed out that the corresponding positions of the fixed pulley 33 itself connecting shaft and the U-shaped sleeve one 322 and the corresponding positions of the traction wheel 54 itself connecting shaft and the U-shaped sleeve two 53 are provided with force sensors, the connecting shaft of the fixed pulley 33 is supported on the corresponding U-shaped sleeve one 322 through the force sensors at both ends, and the connecting shaft of the traction wheel 54 is supported on the U-shaped sleeve two 53 through the force sensors at both ends, for real-time monitoring of the force data of the fixed pulley 33 and the traction wheel 54.

[0042] The test principle of the testing machine is as follows: when the two ends of the whole insulating rope 8 are subjected to the pressure test pulling force, the front pulley mechanism 3 is moved to the position close to the rear pulley mechanism 3 before the insulating rope 8, one end of the insulating rope 8 is fixed on the rightmost fixed pulley 33 in the rear pulley mechanism 3, then the other end of the insulating rope 8 passes through the strip-shaped hole on the side wall of the test tank 1 and is fixedly connected with the traction wheel 54 after sequentially and staggeringly passing through all the fixed pulleys 33. Finally, the front pulley mechanism 3 is reset and fixed in position through limiting on the front side of the test tank 1, so that the two pulley mechanisms 3 are fixed in the test tank 1 and are distributed front and back. Then the hydraulic rod two 51 is retracted, and one end of the insulating rope 8 is slowly pulled. One end of the insulating rope 8 is subjected to the pulling force and the whole insulating rope 8 is subjected to the force, for simulating the scene of the two ends of the whole insulating rope 8 subjected to the pressure test pulling force, testing the change of the pulling force of the insulating rope 8 in the process of being pulled by the hydraulic rod two 51 and the final limit pulling force value.

[0043] II. After the whole insulation rope 8 is segmented, the multi-segment tension test is performed. Before winding the insulation rope 8, the front pulley mechanism 3 after unlocking is moved to be close to the rear pulley mechanism 3, one end of the insulation rope 8 is fixed on the rear and rightmost fixed pulley 33, then the insulation rope 8 is sequentially and alternately threaded through all the front and rear fixed pulleys 33, the other end of the insulation rope 8 is fixed on the front and leftmost fixed pulley 33, then the pulley mechanism 3 is pushed close to the hydraulic rod one 41, at the same time, the butt joint 43 of the telescopic end of the hydraulic rod one 41 is butt jointed with the butt joint block 42 on the lower side of the base plate 31 of the pulley mechanism 3 and is fixed by the fixing bolt and the fixing nut. Finally, the front row of fixed pulleys 33 is pulled away from the rear row of fixed pulleys 33 by the contraction of the hydraulic rod one 41, the tension of each segment of the insulation rope 8 wound between the front and rear fixed pulleys 33 is tested, the tension change data of each segment of the insulation rope 8 under continuous traction stress, the stress data when finally disconnected and the insulation rope 8 breaking node position are detected, so as to quickly obtain the different segment tension test data of the insulation rope 8 for data analysis and comparison.

[0044] The scheme sets the test tank 1 and two groups of pulley mechanisms 3 (one group is fixed and the other group is slidable), uses the principle of natural bending and reversing of pulleys, and winds the long-size insulation rope 8 (100m-300m) into multiple segments in the test tank 1 with limited length. The two ends of the whole insulation rope 8 can be separately pulled by the traction mechanism two 5 for tension test, and the whole insulation rope 8 can be divided into multiple uniform segments for simultaneous tension test of the single insulation rope 8, which reduces the required space span for test, reduces the requirements for indoor space and capital construction cost, and overcomes the defects of the traditional tension machine requiring super-long stroke and space.

[0045] The scheme adopts the pulley set to guide the insulation rope 8, one winding mode can adapt to two different test modes according to the test needs of the insulation rope 8. In the insulation rope 8 segmented test, the traditional insulation rope 8 segmented test does not need to repeatedly adjust the clamping position, and does not need to apply any clamping force to the middle segment of the insulation rope 8. The insulation rope 8 only contacts with the fixed pulley 33 with low friction resistance, which not only solves the problem of low efficiency caused by repeatedly clamping the insulation rope 8 at different positions in the traditional segmented test method, but also avoids the huge concentrated stress generated by the clamping device on the different positions of the middle segment of the insulation rope 8 during clamping, thereby completely eliminating the problems of local crushing, broken strands or internal injury of the insulation rope 8 caused thereby, and ensuring the integrity of the test sample and the authenticity and accuracy of the test data.
