Medium and low voltage switchgear needs to be detected. Before the test, test wiring is required. Existing test wires are all manually wired by test personnel. Each test wire is relatively heavy, resulting in time-consuming and laborious manual wiring, increasing the work intensity. Moreover, manual wiring easily causes friction between the test wire and the ground, thus reducing the service life of the test wire. Summary of the Invention

[0003] The purpose to be achieved by the present invention is to provide an automatic wiring device for medium and low voltage switchgear detection, which can automatically install the test wire on the medium and low voltage switchgear, thus reducing the wiring work intensity.

[0004] To solve the above technical problems, the present invention is realized through the following technical solutions: an automatic wiring device for medium and low voltage switchgear detection, including a box body and a manipulator. An inlet hole for the test wire to pass through is provided on the box body. A horizontal optical rod is provided inside the box body. A vertical plate is provided on the horizontal optical rod. A wiring pipe for fixing the test wire is provided at both the upper and lower ends of the vertical plate, and the wiring pipe is movably connected to the box body. A connection plug connected to the test wire is provided at one end of the wiring pipe. A drag chain connected to the vertical plate is provided at the bottom end of the box body. A pulling ring is provided between the upper and lower wiring pipes. A clamping part connected to the pulling ring is provided on the manipulator. The pulling ring includes a front pulling plate, a rear pulling plate and a connecting rod provided between the front pulling plate and the rear pulling plate. When the clamping part abuts against the front pulling plate, the wiring pipe is pulled forward by the pulling force of the manipulator.

[0005] Preferably, a horizontal through hole is provided on the wiring pipe, and the test wire passes through the horizontal through hole and is connected to the connection plug after passing through the inlet hole.

[0006] Preferably, screws are provided at both ends of the connecting rod. Adjusting washers and / or adjusting nuts are provided on the screws. The adjusting washers and / or adjusting nuts are provided between the front pulling plate and the connecting rod and / or between the rear pulling plate and the connecting rod.

[0007] Preferably, the clamping part includes a push block and a flange plate connected to the manipulator, and the flange plate and the push block are of an integral structure.

[0008] Preferably, a limiting component is provided between the vertical plate and the horizontal optical rod, and the limiting component includes a limit switch and a limiting plate.

Detailed implementation manners

[0023] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, an automatic wiring device for medium and low voltage switchgear cabinet detection includes a box body 1 and a manipulator 7. The manipulator in this embodiment is a prior art and will not be described in detail in this embodiment. An inlet hole 11 is provided on the box body 1. A horizontal optical rod 4 is provided inside the box body 1. A vertical plate 40 is provided on the horizontal optical rod 4. A wiring pipe 2 for fixing test wires is provided at both the upper and lower ends of the vertical plate 40, and the wiring pipe 2 is movably connected to the box body 1. A connecting plug 3 is provided at one end of the wiring pipe 2. A drag chain 14 connected to the vertical plate is provided at the bottom end of the box body. A pulling ring 6 is provided between the upper and lower wiring pipes. A clamping part 71 connected to the pulling ring is provided on the manipulator 7. The pulling ring 6 includes a front pulling plate 61, a rear pulling plate 62 and a connecting rod 63 provided between the front pulling plate and the rear pulling plate. When the clamping part abuts against the front pulling plate, the wiring pipe is pulled forward by the pulling force of the manipulator. When the clamping part abuts against the rear pulling plate, the wiring pipe is driven backward by the acting force of the manipulator.

[0024] It is connected to the pulling ring between the clamping part on the manipulator and the wiring pipe. Since the pulling ring is arranged in the structure of a front pulling plate, a rear pulling plate and a connecting rod, during use, when the clamping part abuts against the front pulling plate, due to the acting force of the clamping part on the front pulling plate, the front pulling plate can move forward under the action of the manipulator. When the clamping part abuts against the rear pulling plate, due to the acting force of the clamping part on the rear pulling plate, the rear pulling plate can move backward under the action of the manipulator. Therefore, in the present invention, the manipulator acts on the clamping part to drive the linear movement of the wiring pipe on the box body. Since the connecting plug is provided on the wiring pipe, the connecting plug can be automatically inserted as the wiring pipe moves, so that the test wire can be automatically installed on the medium and low voltage switch cabinet, thereby reducing the working intensity of wiring and improving the wiring efficiency. Secondly, the setting of the horizontal optical rod and the vertical plate can ensure the straightness of the wiring pipe during movement, thereby ensuring the installation quality of the connecting plug. Finally, the setting of the cable carrier can fix the test wire on the cable carrier, so that the test wire can be protected from direct friction with the ground, thereby improving the service life of the test wire. Moreover, the wiring pipe can also solve the problem of cross winding between the test wires, avoiding the problem of ineffective wiring caused by winding.

[0025] Both ends of the connecting rod 63 are provided with screws 64. Adjusting washers 65 or / and adjusting nuts 66 are provided on the screws. The adjusting washers or / and adjusting nuts are arranged between the front pulling plate and the connecting rod or / and between the rear pulling plate and the connecting rod. A locking screw 67 is provided on the screw 64. The front pulling plate and the rear pulling plate are both locked on the screw by the locking screw, which can realize the quick installation and fixation of the front pulling plate and the rear pulling plate, and can adjust the distance between the front pulling plate and the rear pulling plate to meet different installation requirements. Secondly, by adjusting the thickness or quantity of the adjusting washers and / or adjusting nuts to adjust the distance between the front pulling plate and the rear pulling plate, the precise adjustment of the gap can be realized, ensuring the precise clamping of the clamping part and improving the clamping efficiency of the clamping part. The clamping part 71 includes a push block 72 and a flange 73 connected to the manipulator, and the flange and the push block are of an integral structure. The clamping part is arranged in the structure of a flange and a push block. The flange can increase the contact area between the clamping part and the manipulator and improve the fixing quality of the clamping part. Secondly, setting the flange and the push block as an integral structure can simplify the installation process between the flange and the push block and improve the installation strength of the whole clamping part.

[0026] A horizontal through-hole 20 is provided in the middle of the wiring pipe. After passing through the inlet hole, the wire is connected to the connecting plug 3 through the horizontal through-hole, which can protect the test wire. A limiting component 41 is provided between the vertical plate 40 and the horizontal optical rod 4. The limiting component 41 includes a limit switch 42 and a limit plate 43, which can effectively limit the moving displacement of the vertical plate 40 on the horizontal optical rod 4. The limit switch 42 and the limit plate 43 have good limiting effects and are convenient for installation and disassembly. The limit switch 42 is arranged on the horizontal optical rod 4, and the limit plate 43 is arranged on the vertical plate 40. The limit plate 43 includes a horizontal part and a vertical part. The horizontal part is arranged at the bottom or top of the vertical part. In this embodiment, the horizontal part is arranged at the bottom of the vertical part, which does not affect the installation of the horizontal optical rod. The vertical part is fixedly connected to the vertical plate 40. It is also possible to arrange the limit switch 42 on the vertical plate 40 and the limit plate 43 on the horizontal optical rod 4. Arranging the limit plate 43 on the vertical plate 40 can reduce the movement of the limit switch 42 and ensure the service life of the limit switch 42.

[0027] A magnetic attraction component 5 is provided between the rear side wall of the box body 1 and the vertical plate 40. The magnetic attraction component 5 includes a first magnet 51 and a second magnet 52 that attract each other. The setting of the magnetic attraction component 5 can ensure that the vertical plate 40 can return to the initial position. The magnetic attraction component 5 is set as the first magnet 51 and the second magnet 52. Since there is a good attraction force between the magnets, the attraction force can be improved. The first magnet 51 is arranged on the vertical plate 40, and the second magnet 52 is arranged on the rear side wall of the box body 1. It is also possible to arrange the first magnet 51 on the rear side wall of the box body 1 and the second magnet 52 on the vertical plate 40. The installation and disassembly are convenient and the connection is reliable.

[0028] A fixing block 44 for fixing the first magnet 51 is provided on the vertical plate 40. A horizontal connection hole matching with the horizontal optical rod 4 is provided on the fixing block 44. A cross beam 12 is provided on the rear side wall of the box body 1, and a fixing bracket 13 for fixing the second magnet 52 is provided on the cross beam 12. The fixing block 46 can realize the quick installation and fixation of the first magnet 51. The setting of the horizontal connection hole enables the fixing block 44 to slide synchronously with the vertical plate 40. The cross beam 12 can play a certain role in supporting and strengthening the box body 1. The fixing bracket 13 can realize the fixation of the second magnet 52, improve the fixing quality of the second magnet 52 on the cross beam 12, and reduce the distance between the first magnet 51 and the second magnet 52, so that the attraction force between the second magnet 52 and the first magnet 51 can pull the vertical plate 40 to slide freely on the horizontal optical rod 4.

[0029] A connecting plate 45 connected to the drag chain 14 is provided on the vertical plate 40, and the connecting plate and the vertical plate are of an integral structure, which can improve the connection quality between the vertical plate and the drag chain, optimize the internal space of the entire box body. Setting the connecting plate and the vertical plate as an integral structure can simplify the installation process between the connecting plate and the vertical plate and improve the connection strength of the entire connecting plate. A support beam is provided at the top of the box body 1, which can strengthen the box body and improve the fixing quality of the manipulator. The support beam and the box body are of an integral structure, which can simplify the installation process between the support beam and the box body and improve the support strength of the support beam.
