Problems solved by technology

The high-voltage line locking device is a part connected to the line to be repaired. It is usually used in conjunction with the grounding rod to complete the safe conduction work. The existing high-voltage line locking fixture used in conjunction with the grounding rod can be adapted during use. Permanent adjustments, such as height adjustment, tilt angle adjustment, etc., but most of them are fixed by mechanical nuts, which require manual operation at high altitude with corresponding tools. However, high-altitude operations are very inconvenient for maintenance personnel to operate; Need to adjust the lifting and horizontal angle separately, the operation steps are cumbersome and the structure is complicated

Embodiment 2

[0049] as attached figure 1 , 2 , 3, 4, 5, 6, and 7, the above scheme can further set the rack and pinion structure as a ball screw structure, and the output shaft of the three-phase asynchronous motor 5 is fixedly connected to the screw, and the three-phase asynchronous motor 5. After electrification, the lead screw is driven to rotate, and the nut meshed with the lead screw is transformed into a linear motion of the nut. The nut is slidably connected with the movable curved arm 14. Through the linear motion of the nut, the movable curved arm 14 drives the movable jaw 1 to rotate. , so as to realize the locking of high-voltage lines.

Embodiment 3

[0051] as attached figure 1 , 2 , 3, 4, 5, and 6, the three-phase asynchronous motor 5 can be further replaced by an air pump as a power source, the piston of the air pump is fixedly connected with a linear guide rail, and one end of the linear guide rail is fixedly connected There is a pin shaft 17, and the linear guide rail drives the pin shaft 17 to move upwards, and the deep groove ball bearing on the pin shaft 17 slides in the straight groove of the movable curved arm 14, driving the movable curved arm 14 to rotate, thereby realizing the locking of the high-voltage line, and the linear guide rail The sliding guide rail slide block is fixedly connected on the fixed plate 4, and the linear guide rail slides in the guide rail slide block, and a limit position needs to be fixedly set on the linear guide rail to prevent the slide block from falling off.

Embodiment 4

[0053] as attached Figure 4 As shown, the guide block 9 in this preferred solution can be further set as two nylon or wear-resistant material guide bars, which are respectively fixed on the fixed plate, on both sides of the rack 8, so as to realize the linear movement of the rack 8.

Abstract

The present invention relates to the field of electric safety, in particular to an automatic locking device in a high-voltage grounding maintenance device, comprising an insulating rod, a fixing base fixedly connected to the insulating rod, a fixing arm fixedly connected to the fixing base, and the The fixed arm is rotatably connected to the movable arm and the driving device; the driving device is fixedly connected to the fixed seat; the present invention adopts the power driving device, which improves the manual labor into manual automatic control, which saves the labor of the maintenance personnel and saves labor in the unit. Improve work efficiency within a short time; through the meshing of the gear and the rack, the rack drives the rotating arm to rotate to realize the locking action of the locking mechanism. This transmission mode moves smoothly and avoids the instability of automatic equipment in high-altitude operations; it has a wide The scope of application can also be used in other technical fields. This device is easy to use, and at the same time has a good clamping force on the charged body, and the contact is firm, ensuring the safety of the maintenance personnel.

Description

technical field [0001] The utility model relates to a locking device, in particular to an automatic locking device, which belongs to electric engineering safety auxiliary tools. Background technique [0002] In the daily maintenance of high-voltage lines, grounding protection work is required to ensure the safety of workers. The high-voltage line locking device is a part connected to the line to be repaired. It is usually used in conjunction with the grounding rod to complete the safe conduction work. The existing high-voltage line locking fixture used in conjunction with the grounding rod can be adapted during use. Permanent adjustments, such as height adjustment, tilt angle adjustment, etc., but most of them are fixed by mechanical nuts, which require manual operation at high altitudes with corresponding tools. However, high-altitude operations are very inconvenient for maintenance personnel to operate; Need to adjust the lifting and horizontal angle separately, the opera...
