Description

Technical Field

[0001] The utility model relates to the technical field of test cable sampling, in particular to a voltage withstand test cable sampling device. Background Art

[0002] Before conducting a withstand voltage test on a cable, it is necessary to cut a section of the cable as a test cable. The existing test cable sampling device cuts off a fixed-length test cable, and then cuts openings on the surface of both ends of the cut test cable to connect it to the test circuit. The existing sampling device needs to cut off the cable. If it is necessary to test cables of different lengths, it is necessary to cut off the corresponding length of the cable, resulting in high test costs. At the same time, it is difficult to cut off the cable, which is not conducive to saving the sampling time of the test cable. For this reason, we propose a withstand voltage test cable sampling device that can reduce the test cost. Utility Model Content

A support column is welded on the top of the base, and a crossbeam runs through the inside of the support column. A connecting rod is movably connected to the surface of the crossbeam, and the connecting rod rotates with the central axis of the crossbeam as the rotation axis. A motor is fixed to the side of the connecting rod, and the input end of the motor is electrically connected to an external power supply. The output end of the motor is connected to two parallel cutting discs through a rotating shaft. The two parallel cutting discs can cut the outer sleeve of a test cable into three sections. A groove is provided on one side of the base, and a cross-cutting knife component is installed inside the groove. The cross-cutting knife component can cross-cut the outer sleeve surface in the middle of the three outer sleeves to facilitate stripping of the outer sleeve. A symmetrical knife holder is welded on the top of the base, and a fixed knife plate is welded on the top of the knife holder. The fixed knife plate supports the bottom of the test cable.

[0005] As a further solution of the utility model: fixing blocks are welded on both sides of the base, threaded holes are penetrated through the top of the fixing blocks, the bottom surface of the fixing blocks is coplanar with the bottom surface of the base, and the fixing blocks can be fixed by bolts adapted to the threaded holes.

[0006] As a further solution of the utility model: the cutting disc is coaxially connected to the rotating shaft, and the diameters of the two symmetrical cutting discs are equal, which can ensure that after starting the motor, two openings can be cut synchronously on the test cable.

[0007] As a further solution of the utility model: an installation groove is opened on the side of the support column, and a pneumatic telescopic cylinder is detachably connected to the inside of the installation groove. A telescopic rod is connected through the top of the pneumatic telescopic cylinder. A force-bearing plate is welded to the bottom of the support column. The top of the telescopic rod is movably connected to one side of the force-bearing plate. When the pneumatic telescopic cylinder is started, the pneumatic telescopic cylinder can apply a supporting force to one side of the force-bearing plate through the telescopic rod to adjust the distance between the cutting disc and the test cable.

[0008] As a further solution of the utility model: the cross-cutting knife component includes a hydraulic cylinder, the top of the hydraulic cylinder is connected to a lifting plate, the top of the lifting plate is welded with a cutting blade, the inner wall of the base is provided with a limiting groove adapted to the lifting plate, and the hydraulic cylinder is started, the hydraulic cylinder can pull the cutting blade to move through the lifting plate to perform transverse cutting on the outer casing.

[0009] As a further solution of the utility model: the fixed blade plate is a semicircular cutting blade, and the two fixed blade plates are respectively tangent to the outer contours of the cutting blade discs adapted thereto in the horizontal direction projection, and can cut two blade edges synchronously.

[0010] As a further solution of the utility model: a test cable is clamped on the top of the two fixed blade plates, and a connection port is formed by cutting the surface of the test cable. The length of the connection port is equal to the distance between the two cutting blades. The connection port can be used as an access port for the test circuit to connect a specific length of the test cable to the test circuit.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1.
