Description

Technical Field

[0001] The utility model belongs to the technical field of electric power fittings, and particularly relates to an electric power fitting for ground traction of high-altitude electric poles. Background Art

[0002] The suspension fitting is a key component for fixing high-voltage transmission cables on the aerial cable chain. After the existing electric power fitting is connected to the traction wire, generally, the U-shaped ring and the bolt structure clamp the wire body. After the wire body is clamped, the connection between the U-shaped ring and the bolt is prone to looseness, resulting in the sliding of the traction wire body and affecting the traction effect. Among them, the "suspension clamp of an electric power fitting with a wire harness fixer" disclosed in the application number "CN202023227291.8" is also a technology that is becoming increasingly mature. By adding a traction rubber band between the clamping plate and the inner wall of the through pipe in the suspension clamp of the electric power fitting with a wire harness fixer, when the push screw is turned back, the traction rubber band rebounds to drive the clamping plate to reset, and a limit ring is added to the surface of the clamping plate to limit the end of the push screw. However, this device still has the following defects: after the suspension clamp is installed, when the U-shaped clamping ring and the external traction cable are installed and subjected to a tensile force, the installation angle of the right-angle ring after installation is inclined, affecting the cable installation progress. The long-term angle change is prone to cause a gap at the connection between the right-angle exchange and the suspension clamp, resulting in the loosening of the nut at the connection, expanding the clamping gap of the suspension clamp, and affecting the tightness of the cable clamped inside the suspension clamp. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an electric power fitting for ground traction of high-altitude electric poles, aiming to solve the problems in the prior art that when the U-shaped clamping ring and the external traction cable are installed and subjected to a tensile force, the installation angle of the right-angle ring after installation is inclined, affecting the cable installation progress. The long-term angle change is prone to cause a gap at the connection between the right-angle exchange and the suspension clamp, resulting in the loosening of the nut at the connection, expanding the clamping gap of the suspension clamp, and affecting the tightness of the cable clamped inside the suspension clamp.

[0004] To achieve the above purpose, the utility model provides the following technical solutions: It includes a vertical clamp. On both sides of the top of the vertical clamp, there are clamp seats. A connection hole is opened at the top of the clamp seat. A right-angle ring is arranged in the middle of the clamp seat. A U-shaped clamping ring is arranged at the top of the right-angle ring. An assembly hole is opened at the bottom of the right-angle ring. The connection hole and the assembly hole are threadedly connected by a bolt. An insulating pad is arranged in the middle of the vertical clamp. Card slots are opened on both sides of the top of the clamp seat, and an arcuate clamping plate is snap-fitted in the card slots.

[0005] In the implementation scheme of the electric power fitting for ground traction of high-altitude electric poles of the utility model, a first auxiliary hole is opened in the middle of the card slot, second auxiliary holes are opened on both sides of the arcuate clamping plate, and an auxiliary screw is threadedly connected in the first auxiliary hole and the second auxiliary hole.

[0006] In this solution, the cable is placed in the vertical clamp. When the clamp base is merged, the connection hole and the assembly hole are aligned at this time. A bolt is used to pass through the connection hole and the assembly hole. After the adjacent clamp bases are merged and clamped, the bow-shaped splint is inserted into the card slot. At this time, the two ends of the bow-shaped splint are used to clamp the clamp base to prevent the clamp base from separating. After the bow-shaped splint is inserted into the card slot, the first auxiliary hole and the second auxiliary hole are aligned, and the bow-shaped splint is fixed in the card slot by using an auxiliary screw.

[0007] In an implementation scheme of the electric power fitting for ground traction of an aerial power pole of the present utility model, an anti-loosening nut is threadedly connected to the top of the auxiliary screw, and retaining bars are arranged on both sides of the anti-loosening nut.

[0008] In this solution, after the auxiliary screw is installed, the retaining bar on the anti-loosening nut abuts against the surface of the clamp base to prevent the auxiliary screw from falling off, resulting in the bow-shaped splint falling off from the card slot.

[0009] In an implementation scheme of the electric power fitting for ground traction of an aerial power pole of the present utility model, cross-shaped protrusions are arranged at both ends of the assembly hole, a cross-shaped groove corresponding to the cross-shaped protrusion is opened at one end of the connection hole, and the cross-shaped groove is engaged with the cross-shaped protrusion.

[0010] In this solution, when the clamp base and the right-angle ring are installed, the cross-shaped groove on the connection hole is aligned with the cross-shaped protrusion, and the cross-shaped protrusion is inserted into the cross-shaped groove to fix the installation angle of the right-angle ring, preventing a slight angular rotation of the right-angle ring after installation due to the traction force during the subsequent traction of the U-shaped clamping ring.

[0011] In an implementation scheme of the electric power fitting for ground traction of an aerial power pole of the present utility model, an anti-slip washer is arranged at the other end of the connection hole, and a plurality of anti-slip protrusions are arranged on the surface of the anti-slip washer.

[0012] In this solution, after the screw rod in the connection hole and the assembly hole is installed, when installing the external nut, the anti-slip protrusions on the surface of the anti-slip washer are used to increase the friction with the external thread to prevent the external nut from falling off.

[0013] In an implementation scheme of the electric power fitting for ground traction of an aerial power pole of the present utility model, a plurality of wire arranging grooves are distributed on the inner wall of the vertical clamp, and a plurality of elastic protrusions are arranged on the surface of the insulating pad.

[0014] In this solution, after the traction cable is installed in the vertical clamp, the cables are scattered and placed in the wire arranging grooves. At this time, the elastic protrusions squeeze the cables, and the cables are clamped in the wire arranging grooves to prevent the cables from loosening after being fixed.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1) By inserting the cross bump into the cross groove, the installation angle of the right-angle ring is fixed, avoiding slight angular rotation of the right-angle ring after installation due to the traction force during the subsequent traction of the U-shaped clamping ring, which may cause loosening of the connection after long-term rotation and expand the clamping tightness of the vertical line clamp. The elastic bump presses the cable and clamps the cable in the cable management groove to prevent the cable from loosening after being fixed;

[0017] 2) After inserting the bow-shaped splint into the card slot, the first auxiliary hole is aligned with the second auxiliary hole, and the bow-shaped splint is fixed in the card slot by using the auxiliary screw. The bow-shaped splint prevents the vertical line clamp from loosening and the clamped cable from loosening. The anti-slip bumps on the surface of the anti-slip washer increase the friction with the external thread to prevent the external nut from falling off. BRIEF DESCRIPTION OF THE DRAWINGS
