Technical Field

[0001] The utility model relates to the field of mine circuit detection equipment, in particular to a mine circuit detection equipment with a cable adjustment mechanism. Background Art

[0002] Mine circuit detection equipment uses the partial discharge method that does not destroy the original structure of the cable. It can easily and accurately detect damaged parts of the cable. At the same time, it is also equipped with automatic monitoring software that can detect faults in time and locate the location of the fault, helping mine workers to respond to power supply and other faults in a timely manner.

[0003] During cable power performance testing, the diameter and length of the cable have a significant impact on the loss of power conduction. However, existing testing devices lack a flexible adjustment mechanism when dealing with different cables, which brings a lot of inconvenience to staff.

[0004] Therefore, in view of the fact that the above-mentioned detection device lacks a flexible adjustment mechanism when dealing with different cables, which brings detection troubles to the staff, a mine circuit detection equipment with a cable adjustment mechanism can be designed. Through the threaded adjustment structure and the rotating structure, while detecting cables of different sizes, the detected cables can be automatically reeled up. Utility Model Content

The lifting rod is used to adjust the height of the receiving plate to meet the testing needs of testers of different heights. The cable tester is used to test the electrical performance of the cable. The adjustment component uses a threaded adjustment structure to facilitate the adjustment of cables of different sizes for testing. The winding component is driven to rotate by a motor to achieve winding and releasing of the cable, which is convenient for staff to operate and test the cable. The limiting structure is used to fix the cable tester so that it will not fall from the receiving plate.

[0008] Preferably, the adjustment assembly includes a horizontal plate, a U-shaped seat, an adjustment screw, and a knob; the horizontal plate is hinged to the rear end of the cable detector by a hinge, and there are two groups of U-shaped seats that are symmetrically installed at the front end of the horizontal plate.

The knob is the operating part of the adjustment screw, and the staff drives the adjustment screw to move up and down by rotating the knob.

[0011] Preferably, the winding assembly further includes a No. 2 rotating shaft and a limiting column; the No. 2 rotating shaft is rotatably connected to the inside of the right column and its front end extends forward to the front end of the right column.

When the servo motor is started, the No. 1 rotating shaft receives power through the coupling and rotates, driving the No. 1 rotating shaft to perform the winding operation.

The characteristic of the servo motor 702 is that it can accurately control the rotation speed, so that the cable winding speed can be accurately controlled. The rotation of the No. 1 rotating shaft 704 drives the cable to be wound, thereby avoiding the trouble of manual winding. The function of the No. 2 rotating shaft 705 is the same as that of the No. 1 rotating shaft 704, thereby assisting the cable to be wound. The limit column 706 is a component in the winding assembly for fixing and adjusting the distance between the No. 1 winding drum 707 and the No. 2 winding drum 708. By adjusting the height of the limit column 706, the distance between the No. 1 winding drum 707 and the No. 2 winding drum 708 can be controlled to adapt to cables of different thicknesses. The No. 1 winding drum 707 and the No. 2 winding drum 708 jointly fix the cable on the No. 1 rotating shaft 704 and the No. 2 rotating shaft 705.

At the same time, the No. 2 rotating shaft 705 is rotated due to the rotation of the cable, and then cooperates with the No. 1 rotating shaft 704 to perform a winding operation. The limiting structure includes a limiting frame 801 and a suction cup 802; the limiting frame 801 is fixedly connected to the upper end of the receiving plate 4, and the front and rear inner walls of the limiting frame 801 are provided with suction cups 802.

[0028] When inspecting the cable, the operator first places the cable securely on the second shaft 705. One end of the cable is then passed through the gap between the upper and lower clamping plates 605 and 606 to ensure the cable is positioned correctly. The operator then rotates the knob 604, which causes the adjustment screw 603 to move accordingly, driving the upper clamping plate 605 gradually closer to the cable until the cable is securely clamped between the upper and lower clamping plates 605 and 606, completing the cable fixation.

[0029] After the cable is fixed, the conductive sheet 607 is used to conduct a detailed inspection of the cable to ensure that the quality and performance of the cable meet the standards. After the inspection is completed, the cable is removed from the adjustment assembly, and then the servo motor 702 is started. After the servo motor 702 is started, the No. 1 shaft 704 receives power through the coupling 703 and starts to rotate, thereby driving the No. 1 shaft 704 to perform the winding operation. At the same time, due to the connection between the cable and the No. 2 shaft 705, the rotation of the cable will also cause the No. 2 shaft 705 to rotate synchronously, and then work together with the No. 1 shaft 704 to complete the cable winding operation.

In addition, the limiting structure firmly fixes the cable detector 5 to ensure that it remains stable during operation, solving the problem that the detection device lacks a flexible adjustment mechanism when dealing with different cables, thereby causing detection troubles for the staff.
