DETAILED DESCRIPTION

[0027] The present invention is described in further detail below in conjunction with the embodiments:

[0028] Example 1

[0029] like Figure 1-5As shown, the present invention provides a transposed conductor bending test device, including a bearing plate 1, a test mechanism 1 and a test mechanism 2 are provided on the top of the bearing plate 1, the test mechanism 1 includes two limit components 1 2 and a detection component 1 3, the test mechanism 2 includes a slide rail 1 4 and a detection component 2 5, one end of the slide rail 1 4 is fixedly installed with a fixing seat 401, and two pressure gauges 100 are fixedly installed on the top of the bearing plate 1. Preferably, the limit component 1 2 includes a placement frame 1 201, a screw 1 202, a positioning plate 1 203, The handle 204, the bearing base 205, the two fixing blocks 206 and the two fixing blocks 207, the bearing base 205 is fixedly connected to the top of the bearing plate 1, the placement frame 201 is fixedly installed on the screw 202 and is threadedly connected to the placement frame 201, the positioning plate 203 slides with the inner wall of the placement frame 201 and is rotatably connected to the bottom of the screw 202, the handle 204 is fixedly installed on the handle 204, and the two fixing blocks 207 are respectively fixedly installed at both ends of the placement frame 201 , two fixed blocks 206 are fixedly mounted on both ends of the supporting base 205, and the detection component 3 includes two electric push rods 301, a reciprocating displacement sensor 302, a lower pressure plate 303 and a pressure head 1. The two reciprocating displacement sensors 302 are fixedly mounted on the top of the two fixed blocks 206, the lower pressure plate 303 is connected to one end of the reciprocating displacement sensor 302, the electric push rod 301 is fixedly mounted on the top of the fixed block 207, and the pressure head 1 is fixedly connected to the output end of the electric push rod 301. Then, the detection component 2 5 also includes an electric push rod 2 509, a pressure head 2 510, a mounting plate 511, a reciprocating displacement sensor 2 512 and a lower pressure plate 2 513. The electric push rod 2 509 is fixedly installed on the top of the fixing frame 508, the pressure head 2 510 is fixedly connected to the output end of the electric push rod 2 509, the mounting plate 511 is fixedly connected to the fixing frame 508, the reciprocating displacement sensor 2 512 is fixedly installed on the top of the mounting plate 511, and the lower pressure plate 2 513 is fixedly installed on the top of the reciprocating displacement sensor 2 512.

[0030] In this embodiment, the staff can select one of the test mechanism 1 and the test mechanism 2 according to the model of the transposed conductor and the test method. When using the test mechanism 1, the staff first inserts the transposed conductor into the placement frame 1 201, and then extends the end of the transposed conductor to be tested from one end, or both ends extend from the two ends of the placement frame 1 201, and then rotates the screw 1 202. After the screw 1 202 is rotated, the height of the positioning plate 1 203 is adjusted so that the positioning plate 1 203 presses the part of the transposed conductor located inside the placement frame 1 201. Then, the electric push rod 1 301 is started. After the electric push rod 1 301 is operated, it pushes the pressure head 1 vertically downward, so that the pressure head 1 moves and squeezes the transposed conductor. At this time, the reciprocating displacement sensor 1 302 transmits the deformation signal of the transposed conductor to the pressure gauge 100, and the pressure gauge 100 displays the test result.

[0031] When using the test mechanism 2, the staff inserts the transposed conductor into the two placement frames 2 502, and then rotates the two screw rods 2 503. After the screw rods 2 503 rotate, the positioning plate 2 504 is driven to move vertically, so that the positioning plate 2 504 limits the transposed conductor, and then the electric push rod 2 509 is started. After the electric push rod 2 509 operates, it pushes the pressure head 2 510 and makes the pressure head 2 510 vertically downward to squeeze the transposed conductor, so that the transposed conductor bends downward. At this time, the reciprocating displacement sensor 2 512 transmits the deformation signal to the pressure gauge 100, and the pressure gauge displays the test results. By setting up multiple different test instruments, different types of tests can be performed on the transposed conductor, thereby improving the quality of the test and having strong applicability.

[0032] The staff can adjust the limiting distance of the transposed conductors by the positioning plate 1 203 and the positioning plate 2 504 according to the specific intensity of the test. The specific method is to adjust the number of rotations of the screw 1 202 and the screw 2 503.

[0033] Example 2

[0034] like Figure 3-5 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, a motor 601 is fixedly installed at one end of the fixing seat 401, and an adjusting screw 602 is fixedly installed at the output end of the motor 601. The detection component 2 5 includes two supporting frames 501, two slide rails 2 506 and a fixing frame 508. The two supporting frames 501 are both threadedly sleeved on the adjusting screw 602. The two slide rails 2 506 are both fixedly connected to the outer wall of the slide rail 1 4. The fixing frame 508 is slidably matched with the two slide rails 2 506. The two supporting frames 501 are both slidably matched with the slide rail 1 4. Component 2 5 also includes two sliding rods 507, two placement frames 2 502, screw 2 503, positioning plate 2 504 and handle 2 505. The two sliding rods 507 are fixedly connected to the inner walls of the two slide rails 2 506, and the fixing frame 508 is slidably sleeved on the two sliding rods 507. The placement frame 2 502 is fixedly installed on the top of the supporting frame 501. The screw 2 503 is threadedly connected to the placement frame 2 502. The positioning plate 2 504 is fixedly installed at the bottom of the screw 2 503 and slides with the inner wall of the placement frame 2 502. The handle 2 505 is fixedly installed at one end of the screw 2 503.

[0035] In this embodiment, when the downward pressure position of the transposed conductor needs to be adjusted, the staff manually adjusts the position of the fixing frame 508 within the two second slide rails 506, and then adjusts the positions of the second electric push rod 509, the second pressure head 510, the mounting plate 511, the second reciprocating displacement sensor 512 and the second downward pressure plate 513, so that different positions of the transposed conductor can be tested, effectively improving the test quality and applicability.

[0036] At the same time, when it is necessary to test transposed conductors of different lengths, the staff starts the motor 601. When the output end of the motor 601 rotates, it drives the adjusting screw 602 to rotate. When the adjusting screw 602 rotates, it engages with one of the supporting frames 501 threads, so that the distance between the two supporting frames 501 is reduced, and then the two placement frames 502 cooperate to limit the transposed conductors of different lengths, and then test transposed conductors of different specifications, thereby increasing the scope of application and further improving applicability.

[0037] Example 3

[0038] like Figure 1 and Figure 7 As shown, based on Example 1, the present invention provides a technical solution: a plurality of fixing rods 102 are slidingly provided at the bottom of the supporting plate 1, a base 101 is fixedly installed at the bottom of the fixing rod 102, a fastening nut 103 is threadedly sleeved on the outer wall of the fixing rod 102, the fastening nut 103 is abutted against the top of the supporting plate 1, a tool box 104 is fixedly installed on the top of the base 101, two box doors 105 are provided at one end of the tool box 104, and a handle 106 is fixedly installed at one end of the box door 105.

[0039] In this embodiment, the staff can open the box door 105 through the handle 106 and then place spare parts and tools in the tool box 104, which facilitates maintenance of the equipment and improves applicability.

[0040] The working principle of the transposed conductor bending test device is described in detail below.

[0041] like Figure 1-7 As shown, the staff can select one of the test mechanism 1 and the test mechanism 2 according to the model and test method of the transposed conductor. When using the test mechanism 1, the staff first inserts the transposed conductor into the placement frame 1 201, and then extends the end of the transposed conductor to be tested from one end, or both ends extend from the two ends of the placement frame 1 201, and then rotates the screw 1 202. After the screw 1 202 is rotated, the height of the positioning plate 1 203 is adjusted so that the positioning plate 1 203 presses the part of the transposed conductor located inside the placement frame 1 201. Then, the electric push rod 1 301 is started. After the electric push rod 1 301 is operated, it pushes the pressure head 1 vertically downward, so that the pressure head 1 moves and squeezes the transposed conductor. At this time, the reciprocating displacement sensor 1 302 transmits the deformation signal of the transposed conductor to the pressure gauge 100, and the pressure gauge 100 displays the test result.

[0042] When using the test mechanism 2, the staff inserts the transposed wire into the two placement frames 2 502, and then rotates the two screws 2 503. After the screws 2 503 rotate, the positioning plate 2 504 is driven to move vertically, so that the positioning plate 2 504 limits the transposed wire, and then the electric push rod 2 509 is started. After the electric push rod 2 509 operates, it pushes the pressure head 2 510 and makes the pressure head 2 510 vertically downward to squeeze the transposed wire, so that the transposed wire bends downward. At this time, the reciprocating displacement sensor 2 512 transmits the deformation signal to the pressure gauge 100, and the pressure gauge displays the test results.

[0043] When it is necessary to adjust the downward pressure position of the transposed conductor, the staff manually adjusts the position of the fixing frame 508 in the two slide rails 506, and then adjusts the positions of the electric push rod 509, the pressure head 510, the mounting plate 511, the reciprocating displacement sensor 512 and the lower pressure plate 513, so that different positions of the transposed conductor can be tested, effectively improving the test quality and having strong applicability;

[0044] At the same time, when it is necessary to test transposed conductors of different lengths, the staff starts the motor 601. When the output end of the motor 601 rotates, it drives the adjusting screw 602 to rotate. When the adjusting screw 602 rotates, it engages with one of the supporting frames 501 threads, so that the distance between the two supporting frames 501 is reduced, and then the two placement frames 502 cooperate to limit the transposed conductors of different lengths, and then test transposed conductors of different specifications, thereby increasing the scope of application and improving applicability.

[0045] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made based on the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
