[0002] Insulation tube is an insulating material, mainly used in electrical equipment to prevent power leakage and sparks, ensuring the safety of operators. It is widely used in interior decoration and urban construction, especially in high-voltage vacuum circuit breakers.

[0003] Since insulating cylinders are widely used outdoors, they need to be subjected to a variety of different tests during their production. First, the insulating cylinder to be tested is cut, and a small part of it is selected as a sample. The sample is installed on a testing machine, and the testing machine is started to begin the corresponding test. However, in the actual testing process, traditional testing can only complete one type of testing operation on the insulating cylinder, namely, it can only perform separate stretching, bending, and extrusion tests on the insulating cylinder, and cannot perform combined testing. At the same time, when conducting the test, it is all carried out in a relatively closed space indoors. Since most insulating cylinders are installed outdoors, especially at high altitudes, the environment is relatively harsh, and there is no simulation operation of the environment in which the insulating cylinder is located. As a result, most of the experimental test results are theoretical results, which have a certain gap with the actual results. Therefore, a combined testing machine for inspecting insulating cylinders is provided. Summary of the Invention

DETAILED DESCRIPTION

[0030] See Figures 1-11 A combined testing machine for inspecting insulating cylinders includes a main body 1, a bracket fixedly connected to the lower side of the main body 1, a plurality of buffer pads fixedly connected to the lower side of the bracket, a fixing seat 2 fixedly connected to the upper inner side of the main body 1, a first hydraulic rod 3 fixedly connected to the lower inner side of the main body 1, an extrusion test plate 4 fixedly connected to the output end of the first hydraulic rod 3, a fixing ring 11 installed on the main body 1, and a clamping assembly installed on the fixing ring 11;

[0031] First, when testing is required, the sample to be tested is mounted on the clamping assembly and the sample is in a slightly tense state. At this time, the first hydraulic rod 3 is started, and the first hydraulic rod 3 drives the extrusion test plate 4 to move downward. The extrusion test plate 4 and the sample are pressed against each other, and the sample is squeezed. The extrusion test of the sample begins. After a period of time, the first hydraulic rod 3 is closed and returned to its original position. The sample is removed and the degree of damage to the sample is checked. The test is performed multiple times, and the force exerted by the extrusion test plate 4 on the sample is adjusted during each experiment. The experimental data are counted and analyzed, and finally the extrusion test effect of the sample is completed.

[0032] The clamping assembly includes an internally threaded barrel 5 fixedly passed through a fixing ring 11, and a plurality of clamping rods 6 are slidably passed through the side walls of the two internally threaded barrels 5. Each clamping rod 6 is fixedly connected to a first frustum 7 on one side located inside the internally threaded barrel 5, and a first spring 8 is fixedly connected between the first frustum 7 and the internally threaded barrel 5. A first externally threaded rod 9 is also threadedly connected to the internally threaded barrel 5, and a second frustum 10 is fixedly connected to the first externally threaded rod 9 on one side located inside the internally threaded barrel 5. The second frustum 10 and the first frustum 7 abut against each other. An anti-slip sleeve is fixedly connected to the side of the clamping rod 6 away from the internally threaded barrel 5, and the anti-slip sleeve is circular in design.

[0033] First, when it is necessary to clamp the sample, both ends of the sample are sleeved on the outside of the internally threaded cylinder 5, and the clamping rod 6 on the outside of the internally threaded cylinder 5 is also located in the sample. While pressing the internally threaded cylinder 5, the first externally threaded rod 9 is rotated to move the first externally threaded rod 9 relative to the internally threaded cylinder 5. The first externally threaded rod 9 drives the second frustum 10 to move. The second frustum 10 and the first frustum 7 abut against each other, squeezing the first frustum 7 and moving the first frustum 7 away from the internally threaded cylinder 5. While the first frustum 7 compresses the first spring 8, it drives the clamping rod 6 until the left and right clamping rods 6 and the sample are tightly abutted, thereby completing the clamping and fixing operation of the sample.

[0034] The upper side of the body 1 is provided with a control assembly for controlling the movement of the fixed ring 11. The control assembly includes a slide 17 rotatably connected to the fixed ring 11. Two mounting grooves 36 are symmetrically provided on the upper side of the body 1. The two slides 17 are slidably connected to the mounting grooves 36. The slide 17 is rotatably connected to the fixed ring 11. A return spring is fixedly connected between the slide 17 and the mounting groove 36. A positioning rod 18 is slidably connected in the slide 17. A second spring 20 is fixedly connected between the positioning rod 18 and the slide 17. The side wall of the positioning rod 18 is fixedly connected There is an oblique head rod 19, and the oblique head rod 19 passes through the slide 17. The bottom of the two mounting grooves 36 are both provided with positioning grooves. One end of the positioning rod 18 extends into the positioning groove. The upper side of the body 1 is slidably connected to the slide 14. Both sides of the slide 14 are fixedly connected to the second hydraulic rod 12. The output ends of the two second hydraulic rods 12 are fixedly connected to the push plate 13. The side wall of the push plate 13 is fixedly connected to the moving head 31. The side wall of the fixed seat 2 is rotatably connected to the second externally threaded rod 15. The second externally threaded rod 15 is threaded through the slide 14.

[0035] First, in the initial state, the lower end of the positioning rod 18 is located in the positioning groove in the mounting groove 36, and the reset spring is in a stretched state. Secondly, before the test, it is determined whether to perform a tensile test or a bending test on the sample according to the actual work needs. When a tensile test is required, the second externally threaded rod 15 is rotated. Since the slide 14 and the body 1 are in a sliding connection, rotating the second externally threaded rod 15 will drive the slide 14 to move relative to the body 1, such as Figure 5As shown, the slide plate 14 will move forward and backward relative to the body 1, and the slide plate 14 will drive the second hydraulic rod 12 and the push plate 13 to move forward and backward relative to the body 1, and the push plate 13 will drive the moving head 31 to move until the push plate 13 and the bevel rod 19 are relative to each other. Then, the second hydraulic rod 12 is started, and the second hydraulic rod 12 drives the push plate 13 and the moving head 31 to move in the direction away from the fixed seat 2. The push plate 13 and the bevel rod 19 are against each other. Under the obstruction of the positioning groove, the bevel rod 19 will first be driven to move upward relative to the slide cylinder 17. While the bevel rod 19 drives the positioning rod 18 to move upward, it compresses the second spring 20 until the positioning rod 18 moves out of the positioning groove. At this time, the obstruction of the positioning groove is lost, which will cause the slide cylinder 17, the fixing ring 11 and the internal threaded cylinder 5 to move away from the fixed seat. The inner threaded cylinder 5 drives the clamping rod 6 and the sample to move in the direction away from the fixed seat 2, thereby forming a stretching effect on the sample. The second hydraulic rod 12 is repeatedly started many times to form multiple stretching operations, and the magnitude of the stretching force each time is different. The experimental data are counted and analyzed, and finally the stretching test effect on the sample is completed. It should be noted here that when the push plate 13 is against the bevel rod 19, the bevel rod 19 will be squeezed to an extreme position, and the extreme position is that the positioning rod 18 is moved out of the positioning groove. At this time, the push plate 13 is still against the bevel rod 19, and a force is applied to the bevel rod 19 to move the slide 17, the fixed ring 11 and the inner threaded cylinder 5. In this state, there is still a gap between the moving head 31 and the fixed ring 11, and the two will not offset each other.

[0036] When the sample needs to be bent, the second external threaded rod 15 is rotated. The difference from the above is that the moving distance of the moving head 31 is changed by the push plate 13. This time, the position of the push plate 13 and the moving head 31 is staggered with the position of the slide 17. That is, when the push plate 13 drives the moving head 31 to move to the left and right sides, the push plate 13 will not collide with the slide 17 when moving, but the moving head 31 will collide with the fixed ring 11. At this time, the second hydraulic rod 12 is started, and the second hydraulic rod 12 drives the push plate 13 and the moving head 31 to move away from the fixed seat 2. The moving head 31 and the fixed ring 1 1 is offset, and under the obstruction of the positioning groove and the positioning rod 18, the fixing ring 11 will not move as a whole. Therefore, when the moving head 31 and the fixing ring 11 are offset, the fixing ring 11 and the internal threaded cylinder 5 will rotate as a whole with the slide cylinder 17 as the center. The internal threaded cylinder 5 drives the clamping rod 6 to rotate with the slide cylinder 17 as the center, thereby causing the clamping rods 6 on both sides to rotate in opposite directions, which will eventually cause the sample to bend. The second hydraulic rod 12 is repeatedly started multiple times to form multiple bending operations, and the bending force each time is different. The experimental data are counted and analyzed, and the bending test effect of the sample is finally completed.

[0037] A friction simulation component is installed on the upper side of the fixed seat 2, and the friction simulation component includes two arc-shaped plates 21, the side walls of the two arc-shaped plates 21 are slidably connected to two control plates 28, the side walls of the two control plates 28 are fixedly connected to a connecting plate 26, and a third spring 27 is fixedly connected between the connecting plate 26 and the arc-shaped plate 21. The lower sides of the two arc-shaped plates 21 are fixedly connected to a fixed plate 29, and the side walls of the fixed plate 29 are fixedly connected to a connecting rod 24. The upper side of the body 1 is slidably connected to two moving frames 16, and the push plate 13 slides through the moving frame 16. The connecting rod 24 extends to the inside of the moving frame 16 and is fixedly connected to a circular plate 34 at one end. A plurality of moving blocks 35 are fixedly connected to the outer circumference of the circular plate 34, and a plurality of moving plates 30 are evenly fixedly connected to the side walls of the push plate 13;

[0038] First, when adjusting the position of the moving head 31, the push plate 13 drives the moving plate 30 to move, and the moving plate 30 and the moving block 35 are against each other, which will cause the moving block 35 to rotate with the connecting rod 24 as the center. The moving block 35 drives the circular plate 34 and the connecting rod 24 to rotate, and the connecting rod 24 drives the fixed plate 29 and the arc plate 21 to rotate. In this process, when the arc plate 21 rotates, the arc plate 21 drives the control plate 28 and the sample to be against each other, which will form an extrusion and friction effect on the sample, simulating the actual use environment of the sample, thereby improving the subsequent detection effect.

[0039] A knocking simulation assembly is installed on the upper side of the curved plate 21. The knocking simulation assembly includes a plurality of knocking protrusions 25 fixedly mounted on the inner side of the curved plate 21. A rotating ring 32 is rotatably connected to the outer side of the connecting rod 24. The rotating ring 32 is slidably connected to the moving frame 16. A fourth spring 33 is fixedly connected between the rotating ring 32 and the moving frame 16. A sliding groove 22 is opened on the upper side of the fixed base 2. A plurality of trapezoidal plates 23 are evenly fixedly connected to the upper side of the sliding groove 22.

[0040] First, when performing stretching or bending testing, the push plate 13 drives the moving frame 16 to move left and right, and the moving frame 16 drives the connecting rod 24, the fixed plate 29 and the curved plate 21 to move through the rotating ring 32. During this process, under the action of the fourth spring 33, the fixed plate 29 is always against the slide groove 22 or the trapezoidal plate 23, which results in that during this process, when the fixed plate 29 moves from being against the slide groove 22 to being against the trapezoidal plate 23, and when the fixed plate 29 moves from being against the trapezoidal plate 23 to being against the slide groove 22, the curved plate 21 will move up and down relative to the fixed seat 2, and the curved plate 21 drives the knocking protrusion 25 to move up and down. The knocking protrusion 25 is against the sample, which will form a knocking effect on the sample, thereby enriching the simulation effect and ultimately improving the subsequent detection effect.

[0041] In the present invention, when it is necessary to clamp the sample, both ends of the sample are sleeved on the outside of the internally threaded cylinder 5, and the clamping rod 6 on the outside of the internally threaded cylinder 5 is also located in the sample. While pressing the internally threaded cylinder 5, the first externally threaded rod 9 is rotated to move the first externally threaded rod 9 relative to the internally threaded cylinder 5. The first externally threaded rod 9 drives the second frustum 10 to move. The second frustum 10 and the first frustum 7 abut against each other, thereby squeezing the first frustum 7 and moving the first frustum 7 away from the internally threaded cylinder 5. While the first frustum 7 compresses the first spring 8, it drives the clamping rod 6 until the left and right clamping rods 6 and the sample are tightly abutted, thereby completing the clamping and fixing operation of the sample.

[0042] Start the first hydraulic rod 3, which drives the extrusion test plate 4 to move downward. The extrusion test plate 4 and the sample are pressed against each other, and the sample is squeezed. The extrusion test of the sample begins. After a period of time, the first hydraulic rod 3 is closed and returned to its original position. The sample is removed to check the degree of damage to the sample. The test is performed multiple times, and the force exerted by the extrusion test plate 4 on the sample is adjusted during each experiment. The experimental data are counted and analyzed, and finally the extrusion test effect of the sample is completed.

[0043] When a tensile test is required, the second externally threaded rod 15 is rotated. Since the slide 14 and the body 1 are in sliding connection, rotating the second externally threaded rod 15 will drive the slide 14 to move relative to the body 1. Figure 5 As shown, the slide plate 14 will move forward and backward relative to the body 1, and the slide plate 14 will drive the second hydraulic rod 12 and the push plate 13 to move forward and backward relative to the body 1, and the push plate 13 will drive the moving head 31 to move until the push plate 13 and the bevel rod 19 are relative to each other. Then, the second hydraulic rod 12 will be started, and the second hydraulic rod 12 will drive the push plate 13 and the moving head 31 to move away from the fixed seat 2. The push plate 13 and the bevel rod 19 will resist each other, and under the obstruction of the positioning groove, the bevel rod 19 will first be driven to move upward relative to the slide cylinder 17, and the bevel rod 19 will drive the positioning As the rod 18 moves upward, the second spring 20 is compressed until the positioning rod 18 moves out of the positioning groove. At this time, the blocking effect of the positioning groove is lost, causing the slide cylinder 17, the fixing ring 11 and the internal threaded cylinder 5 to move away from the fixing seat 2. The internal threaded cylinder 5 drives the clamping rod 6 and the sample to move away from the fixing seat 2, forming a stretching effect on the sample. The second hydraulic rod 12 is repeatedly started multiple times to form multiple stretching operations, and the stretching force each time is different. The experimental data are counted and analyzed, and finally the tensile test effect of the sample is completed;

[0044] When the sample needs to be bent, the second external threaded rod 15 is rotated. The difference from the above is that the moving distance of the moving head 31 is changed by the push plate 13. This time, the position of the push plate 13 and the moving head 31 is staggered with the position of the slide 17. That is, when the push plate 13 drives the moving head 31 to move to the left and right sides, the push plate 13 will not collide with the slide 17 when moving, but the moving head 31 will collide with the fixed ring 11. At this time, the second hydraulic rod 12 is started, and the second hydraulic rod 12 drives the push plate 13 and the moving head 31 to move away from the fixed seat 2. The moving head 31 and the fixed ring 1 1 is offset, and under the obstruction of the positioning groove and the positioning rod 18, the fixing ring 11 will not move as a whole. Therefore, when the moving head 31 and the fixing ring 11 are offset, the fixing ring 11 and the internal threaded cylinder 5 will rotate as a whole with the slide cylinder 17 as the center. The internal threaded cylinder 5 drives the clamping rod 6 to rotate with the slide cylinder 17 as the center, thereby causing the clamping rods 6 on both sides to rotate in opposite directions, which will eventually cause the sample to bend. The second hydraulic rod 12 is repeatedly started multiple times to form multiple bending operations, and the bending force each time is different. The experimental data are counted and analyzed, and the bending test effect of the sample is finally completed;

[0045] When adjusting the position of the moving head 31, the push plate 13 drives the moving plate 30 to move, and the moving plate 30 and the moving block 35 are against each other, which causes the moving block 35 to rotate with the connecting rod 24 as the center. The moving block 35 drives the circular plate 34 and the connecting rod 24 to rotate, and the connecting rod 24 drives the fixed plate 29 and the curved plate 21 to rotate. In this process, when the curved plate 21 rotates, the curved plate 21 drives the control plate 28 to resist the sample, which will form an extrusion and friction effect on the sample, simulating the actual use environment of the sample, thereby improving the subsequent detection effect;

[0046] When performing stretching or bending testing, the push plate 13 drives the moving frame 16 to move left and right, and the moving frame 16 drives the connecting rod 24, the fixed plate 29 and the curved plate 21 to move through the rotating ring 32. During this process, under the action of the fourth spring 33, the fixed plate 29 is always in contact with the slide groove 22 or the trapezoidal plate 23, which results in that during this process, when the fixed plate 29 moves from contacting the slide groove 22 to contacting the trapezoidal plate 23, and when the fixed plate 29 moves from contacting the trapezoidal plate 23 to contacting the slide groove 22, the curved plate 21 will move up and down relative to the fixed seat 2, and the curved plate 21 drives the knocking protrusion 25 to move up and down. The knocking protrusion 25 is in contact with the sample, which will form a knocking effect on the sample, thereby enriching the simulation effect and ultimately improving the subsequent detection effect.
