[0002] During the construction process of relocating power lines across highways, bridges, etc., in order to avoid affecting the passage of traffic and ensure the smooth progress of construction, it is necessary to set up installation frames to support the power cables.

[0003] In the prior art, a Chinese utility model patent document with authorization announcement number CN218732779U discloses a portable crossing frame, in which a cross bar is propped up to a certain height by a first vertical bar and a second vertical bar, and a plurality of insulating cylinders for supporting cables are arranged on the cross bar, and the insulating cylinders are rotatably mounted on the cross bar. When the cable is pulled, the insulating cylinders can rotate relative to the cross bar, thereby converting sliding friction into rolling friction, effectively avoiding the problem of friction damage on the cable surface; however, during the construction process, since the cable cannot be completely tightened and fixed in the annular groove of the insulating cylinder, the cable is easily detached from the annular groove of the insulating cylinder under the influence of external forces such as wind or external vibration.

[0004] Therefore, it is necessary to design a high-voltage power line crossing installation frame for power line relocation that can prevent the cable from escaping from the slide groove of the insulating tube, provide stable support for the cable, and reduce wear on the outside of the cable to solve the current technical problems. Summary of the invention

[0005] In view of the deficiencies in the prior art, the utility model provides a high-voltage power line crossing installation frame for power line relocation, which can prevent the cable from escaping from the slide groove of the insulating tube, stably support the cable, and reduce the wear on the outer side of the cable.

[0006] The technical solution of the utility model is as follows: a high-voltage power line crossing installation frame for power line relocation comprises two parallel column assemblies, a base is provided at the bottom of the column assembly, a crossbeam is provided between the upper ends of the two column assemblies, the end of the crossbeam is connected to the top of the column assembly through a connecting seat, a support shaft is mounted on the top of the crossbeam, insulating cylinders are evenly provided on the support shaft along its axial direction, the insulating cylinder is rotatably provided on the outside of the support shaft, an insulating roller corresponding to the insulating cylinder is rotatably provided above the insulating cylinder, the insulating roller abuts against the top of the insulating cylinder, and both ends of the insulating roller are detachably fixedly connected to the crossbeam.

[0007] A pressing shaft is rotatably arranged inside the insulating roller, and mounting seats are arranged at both ends of the pressing shaft. The mounting seats are detachably fixedly connected to the top of the crossbeam.

[0008] The mounting seat has an axial end support block fixedly arranged at the end of the pressure shaft, and a support block bottom plate is arranged at the bottom of the axial end support block. The support block bottom plate is detachably fixedly connected to the cross beam through a bolt and nut mechanism.

[0009] The column assembly has at least two column units, the column units have two parallel connecting frames, vertical poles are evenly arranged between the two connecting frames, and a diagonal rod is arranged between two adjacent vertical poles; the corresponding connecting frames in two adjacent column units are detachably fixedly connected by a bolt and nut mechanism.

[0010] The connecting seat has a lower connecting plate matched with the top end of the column assembly, and an upper connecting plate corresponding to the crossbeam is vertically fixedly arranged on one side of the lower connecting plate.

[0011] Reinforced side plates are fixedly arranged between both sides of the lower connecting plate and the upper connecting plate.

[0012] Three connecting rings are evenly arranged on the lower connecting plate.

[0013] The base has a base bottom plate, a base connecting frame is fixedly arranged on the top of the base bottom plate, and the column assembly is detachably fixedly assembled on the top of the base connecting frame.
