Description

Technical Field

[0001] The invention relates to the technical field of cable testing, and in particular to a cable tension testing machine. Background Art

[0002] Cables are usually rope-like cables composed of several or several groups of conductors (at least two in each group). Each cable is wrapped with a highly insulating covering layer, with the characteristics of internal power supply and external insulation. When cables are used in engineering projects, due to factors such as laying length and laying environment, there are greater requirements on the tension of the cables. In order to better meet the use needs and ensure construction quality and use, it is necessary to perform tension tests on the cables after production.

[0003] The metal conductors of existing cables are covered with an insulating paper layer. Therefore, workers usually need to manually peel off the metal conductors, manually clamp the metal conductors to a fixture during testing, and use the clamps to clamp the metal conductors before performing a tensile test. However, if the clamps are clamped too loosely, the metal conductors of the cable are likely to fall off at the connection with the fixture. If the clamps are clamped too tightly, the metal conductors of the cable are likely to be damaged at the connection with the fixture, and are flattened due to excessive force, resulting in inaccurate tensile test results for the cable.

[0038] The adjacent sides of the first movable block 5 and the second movable block 6 are fixedly connected with a mounting block 9, the upper surface of the mounting block 9 is provided with a winding column 10, the outer surface of the winding column 10 is fixedly connected with a mounting disk 11, the upper surface of the winding column 10 is provided with an opening 12, and the inside of the opening 12 is installed with a clamping assembly 13.

[0040] The screw 803 is driven to rotate by starting the motor 801. Since the screw 803 is threadedly connected to the U-shaped rod 802, the screw 803 can drive the U-shaped rod 802 and the mounting block 9 on the right to move right along the slide rod 4 during the rotation process. The information is transmitted to the electric control cabinet for processing through the tension sensor, and the cable is subjected to a tension test.

[0041] like Figure 4 and Figure 6 As shown, in this embodiment, the clamping assembly 13 includes a pressure plate 1301 installed inside the opening 12, and a first screw rod 1302 is fixedly connected to the middle of the lower surface of the pressure plate 1301. Of course, the pressure plate 1301 can also be rotatably connected to the first screw rod 1302. The bottom end of the first screw rod 1302 passes through the winding column 10 and is fixedly connected to the first handle 1303. The first screw rod 1302 is threadedly connected to the winding column 10. The lower surface of the pressure plate 1301 is provided with anti-slip grooves, and a clamping groove 1304 is formed between the pressure plate 1301 and the inner bottom wall of the opening 12.

[0042] When in use, the first handle 1303 is turned to drive the first screw rod 1302 to rotate. Since the first screw rod 1302 is threadedly connected to the winding column 10, the first screw rod 1302 can drive the pressure plate 1301 to move upward and expand the clamping groove 1304 during the rotation, and then put the cable end to be tested into the clamping groove 1304 from the opening 12 on the left, and then reverse the first handle 1303 to move the pressure plate 1301 downward to fix the cable in the clamping groove 1304.

[0043] like Figure 2-5 As shown, in this embodiment, the clamping assembly 16 includes a second screw rod 1601 threadedly connected to the connecting rod 15, the top of the second screw rod 1601 is fixedly connected to the second handle 1602, the bottom of the second screw rod 1601 is installed with a pressure plate 1603, the pressure plate 1603 is concentrically arranged with the mounting plate 11, the lower surface of the pressure plate 1603 is provided with an avoidance groove 1604, the avoidance groove 1604 is larger than the diameter of the winding column 10, the pressure plate 1603 is rotatably connected to the second screw rod 1601 through a bearing, a plurality of guide columns 1605 are fixedly connected to the edge of the lower surface of the pressure plate 1603, guide holes 1606 corresponding to the guide columns 1605 are provided on the mounting block 9, the outer surface of the pressure plate 1603 is installed with a guide wheel 1607, and the pressure plate 1603 is larger than the diameter of the mounting plate 11.

[0044] The second screw rod 1601 is driven to rotate by turning the second handle 1602. Since the second screw rod 1601 is threadedly connected to the connecting rod 15, the second screw rod 1601 can drive the pressure plate 1603, the guide column 1605 and the guide wheel 1607 to move downward during the rotation until the guide column 1605 is inserted into the guide hole 1606 on the mounting block 9. At this time, the winding column 10 is located in the avoidance groove 1604, the cable is wound around the outside of the guide wheel 1607, and the left end of the wound cable is fixed by the mounting plate 11 and the pressure plate 1603.

[0045] like Figure 3 and 5 As shown, in this embodiment, the guide wheel 1607 is rotatably connected to the pressure plate 1603 through a pin shaft 1608, the number of guide wheels 1607 is multiple and the sizes are different, and the bottom end of the guide column 1605 is fixedly connected with an arc-shaped guide head 1609.

[0046] By providing multiple guide wheels 1607 of different sizes and locating the guide wheels 1607 on the outside, the downward movement of the pressure plate 1603 will not be affected, so the position of the pressure plate 1603 can be rotated to change the guide wheels 1607, thereby being suitable for detecting cables of different thicknesses.

[0047] Located to facilitate winding of the cable on the right side, such as Figure 7 and Figure 8As shown, in this embodiment, the rotating assembly 17 includes a fixed box 1701 fixedly connected to the lower surface of the right mounting block 9, the right winding column 10 is rotatably connected to the mounting block 9 through a bearing and passes through the fixed box 1701, the outer surface of the winding column 10 located inside the fixed box 1701 is fixedly connected with a worm gear 1702, the worm gear 1702 is meshingly connected with a worm 1703, the other end of the worm 1703 passes through the fixed box 1701 and is fixedly connected with a third handle 1704, the worm 1703 is rotatably connected to the fixed box 1701 through a bearing, the winding column 10 on the left is fixedly connected to the mounting block 9, and the winding column 10 on the right is rotatably connected to the mounting block 9.

[0048] By placing the cable end to be tested into the clamping groove 1304 from the opening 12 on the right, fixing the right end of the cable by the clamping assembly 13 on the right, and then turning the third handle 1704 to drive the worm 1703 to rotate, the worm 1703 can cooperate with the worm wheel 1702 to drive the winding column 10 and the mounting disk 11 to rotate during the rotation process, and the winding column 10 can wind the right end of the cable during the rotation process.

[0049] The technical solution provided by the present invention is that when in use, the first handle 1303 is rotated to drive the first screw rod 1302 to rotate. Since the first screw rod 1302 is threadedly connected to the winding column 10, the first screw rod 1302 can drive the pressure plate 1301 to move upward and expand the clamping groove 1304 during the rotation process, and then the cable end to be tested is placed in the clamping groove 1304 from the opening 12 on the left side, and then the first handle 1303 is reversed to move the pressure plate 1301 downward to fix the cable in the clamping groove 1304, and then the cable is wound around the outer surface of the winding column 10, and then the column 14 and the connecting rod 15 are rotated to rotate the clamping assembly 16 to the upper side of the mounting plate 11 Then, the pressure plate 1603 is rotated to make the guide wheel 1607 of appropriate size located at the lower right side, and then the pressure plate 1603 is kept stationary, and the second handle 1602 is rotated to drive the second screw rod 1601 to rotate. Since the second screw rod 1601 is threadedly connected with the connecting rod 15, the second screw rod 1601 can drive the pressure plate 1603, the guide column 1605 and the guide wheel 1607 to move downward during the rotation, until the guide column 1605 is inserted into the guide hole 1606 on the mounting block 9. At this time, the winding column 10 is located in the avoidance groove 1604, the cable is wound around the outside of the guide wheel 1607, and the left end of the wound cable is fixed by the mounting plate 11 and the pressure plate 1603;

[0050] Then put the cable end to be tested into the clamping groove 1304 from the right opening 12, fix the right end of the cable by the clamping assembly 13 on the right, and then turn the third handle 1704 to drive the worm 1703 to rotate. The worm 1703 can cooperate with the worm wheel 1702 to drive the winding column 10 and the mounting plate 11 to rotate during the rotation. The winding column 10 can wind the right end of the cable during the rotation. At this time, the interlocking of the worm 1703 and the worm wheel 1702 prevents the winding column 10 on the right from rotating. The cable is then wound around the outside of the left and right guide wheels 1607. The motor 801 is then started to drive the screw 803 to rotate. Since the screw 803 is threadedly connected to the U-shaped rod 802, the screw 803 can drive the U-shaped rod 802 and the mounting block 9 on the right to move to the right along the slide bar 4 during rotation. The information is transmitted to the electric control cabinet for processing through the tension sensor, and the cable is subjected to a tension test.

In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0053] The above is only a preferred embodiment of the present invention.

These improvements and modifications should also be regarded as the scope of protection of the present invention.
