Description

Technical Field

[0001] The utility model relates to the technical field of power grid distribution power guiding frames, in particular to a power grid distribution power guiding frame. Background Technique

[0002] The power grid is an overall entity composed of substations of various voltages and transmission and distribution lines in the power system, also known as the power network, which includes three units: transformation, transmission, and distribution, and has the functions of transporting and distributing electric energy and changing voltage. When the power grid is erected, a power guiding frame is required to limit, support, and guide it, restricting displacement in other directions;

[0003] For example, a power guiding frame for power grid distribution disclosed in the authorized announcement number CN216290114U includes mounting rings arranged at equal intervals and fixed on a column. Both sides of the top of the column are fixedly installed with cross arms. The two ends of the outer wall of the cross arm and the column are supported and connected by T-shaped inclined rods. A wire clamp connected to an external cable is installed at the top of the cross arm. The wire clamp penetrates through the cross arm at the bottom end and extends to an adjusting mechanism inside the cross arm. The adjusting mechanism includes a rotating handle located at the center of the outer wall of the cross arm. The rotating shaft on the rotating handle penetrates through the cross arm and extends to a rotating gear inside the cross arm. The two ends of the rotating gear are respectively meshed and driven with a left gear plate and a right gear plate. The outer walls of the left gear plate and the right gear plate are connected with sliding grooves adapted to them along the length direction of the inner wall of the cross arm. When the device is in use, by rotating the handle, the gear is driven to mesh with the gear plate, and by using the movement of the gear plate, the wire clamp on the bracket can be moved to the center of the column. The device realizes transmission through the simple meshing of gears and gear plates. Since no relevant components are provided in the device to prevent the gear from rotating back, when the cable is pulled closer to the middle, the cable has tension and will generate a force opposite to it, which will affect the gears and gear plates, making it impossible to position the cable after it is pulled. At the same time, it may cause the gears and the handle to rotate back, posing a safety hazard to maintenance personnel. Content of the Utility Model

[0004] The purpose of the utility model is to provide a power grid distribution power guiding frame to solve the problem proposed in the above background technique that no relevant components are provided in the device to prevent the gear from rotating back. When the cable is pulled closer to the middle, the cable has tension and will generate a force opposite to it, which will affect the gears and gear plates, making it impossible to position the cable after it is pulled. At the same time, it may cause the gears and the handle to rotate back, posing a safety hazard to maintenance personnel.

Symmetric fixing vertical plates are erected in the middle of the inner side wall of the frame body of the guiding frame main body. Two mounting plates on the same side of the fixing vertical plates are connected through a connecting plate. A double-headed screw rod is horizontally penetrated through the middle of the fixing vertical plate, and the double-headed screw rod is screwed with the fixing nut. An adjusting wheel is arranged in the middle of the rod body of the double-headed screw rod. A positioning block is fixedly arranged at the upper end of the fixing vertical plate on one side of the adjusting wheel. A positioning bolt is horizontally penetrated through the positioning block, and the positioning bolt extends and inserts into the positioning block. This device has stable limiting and is conducive to safe maintenance.

[0006] Preferably, there are two chutes, and there are four groups of sliders in total, and one mounting plate is arranged at the upper end of each group, forming a single sliding structure with stable structure, which is convenient for the corresponding insulating porcelain bottles to move.

[0007] Preferably, adjusting jacks are opened on the side surfaces of the adjusting wheels, and the positioning bolts are screwed with the positioning blocks, which is convenient for using tools to rotate the adjusting wheels and the connection between the positioning bolts and the adjusting wheels.

[0008] Preferably, a connecting frame is fixedly arranged on one side of the guiding frame main body, and an arc-shaped groove is opened in the connecting frame, which is convenient for adapting to the shape of the electric pole and convenient for installation.

[0009] Preferably, a reinforcing plate is fixedly arranged on the side of the connecting frame connected to the guiding frame main body, and the reinforcing plate is fixedly connected to the bottom end of the guiding frame main body, enhancing the overall structural strength and stability of the guiding frame main body.

[0012] By designing parts such as a double-headed screw rod, an adjusting wheel, an adjusting jack, a positioning block, and a positioning bolt, a tool is inserted into the adjusting jack on the side of the adjusting wheel, so that the adjusting wheel drives the double-headed screw rod to rotate. The rotation of the double-headed screw rod is screwed with the fixed nuts in the mounting plates on both sides of the fixed vertical plate, so that the mounting plates approach each other, driving the insulating porcelain bottle to move towards the middle. When the adjusting wheel rotates to the final position, the positioning bolt is screwed with the positioning block, so that the positioning bolt extends into the adjusting wheel to realize another limit for the adjusting wheel. This process is carried out through a bolt driving method, and the restriction on the mounting plate is relatively stable. The positioning bolt is further used to limit the adjusting wheel, so that the positions of the adjusting wheel, the mounting plate, and the insulating porcelain bottle are fixed, which is conducive to safe maintenance.
