Description

Technical Field

[0001] The utility model relates to the field of maintenance platforms, in particular to an electrical instrument maintenance platform. Background Art

[0002] Existing commonly used electrical instruments include multimeters, insulation resistance meters, ground resistance meters, bridges, field strength meters, oscilloscopes, diagrammers, voltage ratio automatic testers, relay protection calibrators, etc. After electrical instruments have been used for a long time, their performance needs to be tested and repaired. Currently, electrical instruments are placed on a rotatable maintenance platform to facilitate maintenance personnel to rotate the maintenance platform, so that they can perform all-round testing and maintenance on the electrical instruments.

[0003] The current maintenance platform has a rotation or clamping function, which is convenient for rotating or clamping the electrical instrument during maintenance. However, since the electrical instrument is placed on the maintenance platform, the bottom of the electrical instrument will fit above the maintenance platform. At this time, personnel will not be able to perform maintenance from the bottom of the electrical instrument. It is usually necessary to loosen the clamping device and then manually lift the electrical instrument up or turn the electrical instrument over. This method is not only time-consuming and labor-intensive, but also manual operation, and there will be certain safety hazards.

[0004] Therefore, it is necessary to invent an electrical instrument maintenance platform. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology.

[0007] The positioning assembly comprises a positioning seat and a driving gear installed inside the positioning seat, a bearing is installed on a side of the positioning seat close to the clamping plate, and a rotating shaft is installed in the middle of the driving gear.

[0008] Based on the above characteristics: when it rotates to the required position, the inspection table can stop rotating, and then the telescopic cylinder can drive the positioning assembly and the clamping plate to move, so that the clamping plate can be clamped and fixed from both sides of the electrical instrument. When the positioning assembly, the clamping plate and the telescopic cylinder move up, the active gear in the positioning seat will be driven to rotate by meshing. As the active gear rotates, the active gear will drive the clamping plate to rotate through the bearing and the rotating shaft. Finally, the clamping plate can drive the electrical instrument to rotate synchronously.

[0009] Preferably, the workbench and the top cover surface are provided with T-shaped grooves, the lower ends of both sides of the workbench are equipped with driving motors, the upper end of the driving motor is equipped with a screw rod, and the screw rod is located between the workbench and the top cover.

[0010] Based on the above characteristics: the T-shaped slide can limit the guide assembly so that the guide assembly can maintain translation when moving, and the drive motor can drive the screw rod to rotate forward and reverse.

[0011] Preferably, the external threaded connection of the screw rod is provided with a movable nut, connecting plates are symmetrically mounted on both sides of the movable nut, and a support plate is mounted on one end of the connecting plate away from the movable nut.

[0013] Preferably, an L-shaped plug plate is installed at the lower end of the positioning seat, and anti-dropping sliding blocks are symmetrically installed on both sides of the L-shaped plug plate.

[0014] Based on the above characteristics: when the positioning seat is raised or lowered, the positioning seat will be guided and limited by the L-shaped plug plate and the anti-dropping slider to keep the splint in a vertical moving state.

[0015] Preferably, the guide assembly includes a guide plate and a convex tooth provided on one side of the upper end of the guide plate, a guide slot is provided in the middle of the lower end of the guide plate, and anti-slip grooves are symmetrically provided on both sides of the guide slot.

[0016] Based on the above characteristics: when the splint and the positioning assembly rise upward, the driving gear on the inner side of the positioning seat will mesh with the convex teeth. At this time, the guide plate and the convex teeth are fixed, and the driving gear will rotate and drive the splint to rotate through the rotating shaft. When the splint rotates, the electrical instrument clamped in the middle of the splint will also flip over.

[0017] Preferably, the L-shaped plug plate is slidably connected to the guide slot, and the anti-slip sliding block is slidably connected to the anti-slip groove.

[0020] Based on the above features: the upper and lower ends of the guide plate are slidably connected with the T-shaped slide block and the T-shaped slide groove, so that the guide plate can be telescopically adjusted following the clamping plate and the positioning assembly.

[0021] The beneficial effects of the utility model are:

[0022] 1. When it is necessary to lift or turn over the electrical instrument, the driving motor can drive the screw to rotate. When the screw rotates, the movable nut will drive the telescopic cylinder, the clamping plate and the positioning assembly to move through the connecting plate and the support plate. At this time, the electrical instrument will be lifted upward. When the driving gear on the inner side of the positioning seat is engaged with the convex teeth, the guide plate and the convex teeth are fixed, and the driving gear will rotate, and drive the clamping plate to rotate through the rotating shaft. When the clamping plate rotates, the electrical instrument clamped in the middle of the clamping plate will also be turned over, without manual turning over, which is simple and convenient.

[0023] 2. The upper and lower ends of the guide plate are slidably connected by T-shaped sliders and T-shaped slide grooves. When the positioning seat is raised or lowered, the positioning seat will be guided and limited by the L-shaped plug plate and the anti-slip slider to keep the splint in a vertical moving state. When the splint is telescopically adjusted, the guide plate can be driven to move synchronously through the L-shaped plug plate and the anti-slip slider to avoid separation of the guide plate and the positioning seat, thereby improving the overall practicality.
