Description

Technical Field

[0001] This utility model relates to the field of cable insulation layer testing technology, and specifically to a cross-linked cable insulation layer testing device. Background Technology

[0002] Cross-linked cables are power cables with cross-linked polyethylene as the insulation layer. Through chemical or physical methods, the polyethylene molecular chains are cross-linked to form a three-dimensional network structure, which significantly improves heat resistance, mechanical strength and electrical performance. The insulation layer of cross-linked cables provides current isolation and improves the cable's pressure resistance and corrosion resistance.

[0003] Currently, in the production process of cross-linked cables, testing devices are used to inspect the surface of the cross-linked electrical insulation layer to detect defects such as bubbles and cracks. However, the existing cross-linked cable insulation layer testing devices have fixed reels and cameras that cannot be adjusted according to the cable diameter. Therefore, a cross-linked cable insulation layer testing device is proposed. The first and second cameras are fixed to the outside of the side plate through the first and second plate sleeves and can move up and down according to the cable diameter. The rotating screw can push the second structural plate to move through the internal threaded sleeve, which makes it easy to adjust the distance between the first and second reels according to the cable diameter. Utility Model Content

[0004] To address the problems in the prior art, this utility model provides a cross-linked cable insulation layer detection device. The first camera and the second camera are fixed to the outside of the side plate by the first plate sleeve and the second plate sleeve, and can move up and down according to the cable diameter. The rotating screw can push the second structural plate to move through the internal thread sleeve, which makes it easy to adjust the distance between the first wire clamping wheel and the second wire clamping wheel according to the cable diameter.

[0005] The technical solution adopted by this utility model to solve its technical problem is a cross-linked cable insulation layer detection device, including a first structural plate. A reduction motor is installed on one side of the first structural plate through a mounting bracket. The output shaft of the reduction motor located at the top of the first structural plate is fixedly sleeved with a first wire-clamping wheel through a flat key. A second structural plate is provided on the other side of the first structural plate. A second wire-clamping wheel is rotatably connected to the top of the second structural plate through a shaft.

[0006] One end of the first structural plate is fixed with a crossbeam by bolts. A display screen is mounted on the bottom of the crossbeam by a mounting bracket. One end of the crossbeam is fixed with a side plate by bolts. A first plate sleeve is fitted on the outside of the side plate. A first camera is mounted on one end of the first plate sleeve by a mounting bracket. A second plate sleeve is fitted on the outside of the side plate located at the top of the first plate sleeve. A second camera is mounted on one end of the second plate sleeve by a mounting bracket.

[0007] By adopting the above technical solution, the geared motor drives the first wire clamping wheel to rotate, which pushes and assists the cross-linked cable clamped by the first and second wire clamping wheels to move. The first and second plate sleeves move up and down to adjust the distance between the first and second cameras. The first and second cameras take pictures of the surface during the movement of the cross-linked cable.

[0008] Specifically, an internal threaded sleeve is welded to the side of the second structural plate away from the first structural plate, and a screw is threaded through the internal threaded sleeve. One end of the screw is rotatably connected to one side of the first structural plate through a bearing.

[0009] Specifically, the first structural plate is connected to an auxiliary rod on one side of the bottom of the screw via a threaded groove, and the auxiliary rod passes through the second structural plate.

[0010] Specifically, a slot is provided on one side of the side plate, and fixing bolts are connected to one side of the first plate sleeve and the second plate sleeve through threaded grooves.

[0011] Specifically, a limit block is welded to the top of one side of the side plate.

[0012] Specifically, the signal output terminals of the first and second cameras are electrically connected to the signal input terminal of the display screen via a power cord.

[0013] The beneficial effects of this utility model are:

[0014] The cross-linked cable insulation layer detection device of this utility model can adjust the distance between the first and second wire clamping wheels by rotating the screw and pushing the second structural plate through the internal threaded sleeve. The distance between the first and second plate sleeves can be adjusted by moving the first and second plate sleeves up and down, thereby enabling the clamping and detection of cross-linked cables of different diameters.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] The first and second cameras are fixed to the outside of the side plate by the first and second plate sleeves, and can move up and down according to the cable diameter. Rotating the screw can push the second structural plate to move through the internal threaded sleeve, facilitating adjustment of the distance between the first and second cable clamping wheels according to the cable diameter. Figure 1-5 As shown, the cross-linked cable insulation layer detection device of this utility model includes a first structural plate 1. A reduction motor 10 is mounted on one side of the first structural plate 1 by a mounting bracket. The output shaft of the reduction motor 10 located at the top of the first structural plate 1 is fixedly sleeved with a first wire clamping wheel 5 by a flat key. A second structural plate 2 is provided on the other side of the first structural plate 1. A second wire clamping wheel 6 is rotatably connected to the top of the second structural plate 2 by a shaft.

[0024] One end of the first structural plate 1 is fixed with a crossbeam 3 by bolts. A display screen 11 is mounted on the bottom of the crossbeam 3 by a mounting bracket. One end of the crossbeam 3 is fixed with a side plate 4 by bolts. A first plate sleeve 12 is fitted on the outside of the side plate 4. A first camera 13 is mounted on one end of the first plate sleeve 12 by a mounting bracket. A second plate sleeve 14 is fitted on the outside of the top of the first plate sleeve 12 on the side plate 4. A second camera 15 is mounted on one end of the second plate sleeve 14 by a mounting bracket.

[0025] In use, the geared motor 10 drives the first wire clamping wheel 5 to rotate, pushing and assisting the cross-linked cable held by the first wire clamping wheel 5 and the second wire clamping wheel 6 to move. The first plate sleeve 12 and the second plate sleeve 14 move up and down to adjust the distance between the first camera 13 and the second camera 15. The first camera 13 and the second camera 15 take pictures of the surface during the movement of the cross-linked cable.

[0026] For example, such as Figure 2 As shown, the present invention also includes an internal threaded sleeve 7 welded to the side of the second structural plate 2 away from the first structural plate 1, and a screw 8 is sleeved through the internal threaded sleeve 7. One end of the screw 8 is rotatably connected to one side of the first structural plate 1 through a bearing.

[0027] In use, rotating the screw 8 can push the second structural plate 2 to move through the internal threaded sleeve 7.

[0028] For example, such as Figure 2 As shown, the present invention also includes an auxiliary rod 9 connected to one side of the first structural plate 1 at the bottom of the screw 8 via a threaded groove, the auxiliary rod 9 passing through the second structural plate 2.

[0029] In use, the auxiliary rod 9 can prevent the second structural plate 2 from rotating with the screw 8 without affecting its movement.

[0030] For example, such as Figure 5 As shown, the present invention also includes a slot 16 on one side of the side plate 4, and fixing bolts 17 connected to one side of the first plate sleeve 12 and the second plate sleeve 14 through threaded grooves.

[0031] When in use, tighten the fixing bolt 17 so that one end is inserted into the slot 16 to fix the first plate sleeve 12 and the second plate sleeve 14 after they have moved up and down.

[0032] For example, such as Figure 5 As shown, the present invention also includes a limiting block 18 welded to the top of one side of the side plate 4.

[0033] When in use, the limiting block 18 is designed to prevent the first sleeve 12 and the second sleeve 14 from falling off the top of the side plate 4.

[0034] For example, such as Figure 4 , Figure 5 As shown, the present invention also includes that the signal output terminals of the first camera 13 and the second camera 15 are electrically connected to the signal input terminal of the display screen 11 via a power cord.

[0035] When in use, the images captured by the first camera 13 and the second camera 15 are transmitted to the display screen 11 for easy viewing by personnel.

[0036] When using this utility model, the operator installs the device on the cross-linked cable winding line, so that the cross-linked cable moves between the first wire clamping wheel 5 and the second wire clamping wheel 6, and connects the device to an external power source using a power cord.

[0037] Rotating screw 8 pushes the second structural plate 2 toward the first structural plate 1 through the internal threaded sleeve 7, causing the second wire clamping wheel 6 to move toward the first wire clamping wheel 5, thereby clamping the cross-linked cable with the second wire clamping wheel 6 and the first wire clamping wheel 5. Turning on the reduction motor 10 drives the first wire clamping wheel 5 to rotate, assisting the cross-linked cable to move between the first wire clamping wheel 5 and the second wire clamping wheel 6.

[0038] The first sleeve 12 and the second sleeve 14 are fitted onto the outside of the side plate 4. The first sleeve 12 and the second sleeve 14 are moved up and down to adjust the height of the first camera 13 and the second camera 15. They are then tightened so that one end is inserted into the slot 16 to fix the first sleeve 12 and the second sleeve 14 after they have been moved up and down. The first camera 13 and the second camera 15 take pictures of the surface of the cross-linked cable when it moves. The pictures are transmitted to the display screen 11 and displayed so that personnel can observe the surface of the cross-linked cable and detect whether there are defects such as bubbles or cracks on the surface of the cross-linked cable.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
