[0001] The utility model relates to the technical field of high-voltage line installation devices, in particular to a high-voltage line porcelain bottle installation and fixing device. Background Art

[0002] The high-voltage line porcelain cylinder, officially known as the insulator, is a key component used to support the conductors in high-voltage transmission lines and act as an insulator; the high-voltage line porcelain cylinder needs to be connected and installed to the high-voltage power tower through a special fixing or lifting device.

[0003] Most of the existing fixing devices lack a mechanism that can output a large driving force to drive the high-voltage line porcelain bottle to implement position sliding adjustment. They mostly rely directly on manual force output to drive and implement, which is troublesome and inconvenient to operate. After all, manual force is limited. As a result, after the high-voltage line porcelain bottle is bundled or wrapped around the high-voltage line and fixed, when the gravity or pulling force of the high-voltage line acts on the high-voltage line porcelain bottle, it is difficult or impossible to adjust the position of the high-voltage line porcelain bottle. Utility Model Content

[0005] The technical solution proposed by the utility model is: a high-voltage line porcelain bottle installation and fixing device, specifically comprising: an I-shaped fixing frame and a high-voltage line porcelain bottle, the I-shaped fixing frame has four sliding grooves symmetrically opened at the left and right ends of the upper and lower cross bracing plates, and the center of the high-voltage line porcelain bottle is inlaid with a mounting shaft;

[0006] The lower half of the mounting shaft protrudes from the high-voltage line porcelain bottle, and a socket is penetrated through the bottom side of the mounting shaft; a mounting sleeve is slidably installed in each of the four slide grooves along the length direction; the mounting shaft and the mounting sleeve are slidably matched, and a horizontally supported hexagonal positioning shaft is welded to the bottom side of the mounting sleeve, and an L-shaped plug rod is slidably installed on the hexagonal positioning shaft through spring pushing, and the bottom horizontal part of the L-shaped plug rod is plugged and matched with the bottom socket of the mounting shaft; the head end of the L-shaped plug rod is rotatably connected with a threaded propulsion shaft, and four threaded sleeves are symmetrically welded and hoisted at the bottom of the upper and lower cross braces of the I-shaped fixing frame, and the threaded propulsion shaft and the threaded sleeve are screwed together.

[0007] Furthermore, the installation sleeve is arranged vertically and penetrates the slide groove, and two limit rings are welded and sleeved on the middle part of the installation sleeve at upper and lower intervals.

[0008] Furthermore, the two limit rings are slidably fitted with the upper and lower end surfaces of the I-shaped fixing frame cross brace plate.

[0009] Furthermore, the four L-shaped insertion rods and the four threaded propulsion shafts are supported in left and right directions.

[0010] Furthermore, a retaining ring is welded and sleeved on the installation shaft at a position close to the bottom side of the high-voltage line porcelain bottle, and the retaining ring is in abutment contact with the top end of the installation shaft sleeve.

[0011] Furthermore, the vertical bending parts of the L-shaped insertion rod are all welded with finger rings.

It only needs to be slid away from the installation shaft sleeve to be pulled out from the installation shaft to loosen the high-voltage line porcelain bottle. Compared with the fixing device that uses a threaded form to fix the high-voltage line porcelain bottle, it is more convenient to disassemble and loosen the high-voltage line porcelain bottle.

[0015] In addition, the forward and reverse rotating threaded propulsion shaft can drive the L-shaped plug rod and the mounting sleeve to slide left and right, providing a driving force for position adjustment of the high-voltage line porcelain bottle. The propulsion torque that can be output when the threaded propulsion shaft rotates forward and reverse is relatively large. Compared with the existing technology that directly relies on manual output to drive the high-voltage line porcelain bottle to implement position adjustment, the operation is more convenient and labor-saving, and it can be used when the high-voltage line porcelain bottle is bundled or wrapped with the high-voltage line and fixed, and the gravity or pulling force of the high-voltage line acts on the high-voltage line porcelain bottle.
