At the same time, during the use of the T-shaped cross-arm component after installation, the connecting reinforcement component can improve its stability during use, and avoid the problem of lateral rotation offset of the T-shaped cross-arm component under the action of wind in a windy environment. At the same time, when installing the T-shaped cross-arm component, the auxiliary installation clamping mechanism can assist the operator in the installation. During the installation, there is no need for the operator at a high place to apply force to lift the T-shaped cross-arm component to be installed to a high place, thereby improving the safety during installation.

When the sliding distance exceeds the set safety range, a danger signal is fed back to the system and manual maintenance is notified.

[0020] The present invention is provided with a connection reinforcement component. When installing the T-shaped cross arm component, the operator climbs to the distribution network pole tower to install the fixing frame first, and then hoists the T-shaped cross arm component to the installation position by hoisting, and inserts the tight ring into the tight sleeve, and pre-positions the T-shaped cross arm component by clamping the positioning plate into the positioning ring groove, and fixes the T-shaped cross arm component after fine-tuning the installation angle of the T-shaped cross arm component by adjusting the component.

The end moves upward and drives the T-shaped cross-arm assembly to the installation position on the distribution network tower. There is no need for operators on the high distribution network tower to pull the rope to lift the T-shaped cross-arm assembly to the installation position, thereby improving the safety during installation.

When the T-type cross arm component is installed, the cone protrusion can be stored in the inner sleeve by rotating gear three, cooperating with gear four, the movable pressure wheel, the protruding pressure plate and spring two. At this time, the clamping wheel acts as a fixed pulley to improve the safety during installation. When the T-type cross arm component is used subsequently, the cone protrusion is adjusted to extend to the outside of the inner sleeve by rotating gear three, cooperating with gear four, the movable pressure wheel, the protruding pressure plate and spring two. When the clamping wheel clamps the distribution network tower, the inner sleeve can increase the friction of the contact surface and improve the clamping effect. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the clamping wheel 45 acts as a fixed pulley to improve the safety during installation. When the T-type cross arm component is used later, the cone protrusion 456 is adjusted to extend to the outside of the inner sleeve 451 by rotating gear three 454 to cooperate with gear four 455, movable pressure wheel 452, protruding pressure plate 453 and spring two 458. When the clamping wheel 45 clamps the distribution network tower, the inner sleeve 451 can increase the friction of the contact surface and improve the clamping effect.

[0044] The operator carries the fixing frame 2 and climbs to the installation position of the distribution network tower. After adjusting the two sets of fixing frames 2 to the set position, they are clamped and fixed on the distribution network tower by bolts and other fasteners. Then the operator slides the movable block 46 upward. While the movable block 46 slides, it drives the connecting arm 3 44 to rotate. The rotation of the connecting arm 3 44 drives the connecting arm 2 43 and the clamping wheel 45 to rotate away from the distribution network tower. When the movable block 46 moves to the uppermost side, the movable block 46 is fixed by threading the bolts on the fixing frame 2 with the movable block 46.

At this time, the clamping wheel 45 is equivalent to a fixed pulley, and the end tied to the T-shaped cross arm assembly moves upward and drives the T-shaped cross arm assembly to move up to the installation position on the distribution network tower, without the need for the operator on the high distribution network tower to pull the rope to lift the T-shaped cross arm assembly to the installation position;

[0045] When the T-shaped cross arm assembly is moved into place, the operator unties the draw rope and rotates the bolt threadedly connected to the movable block 46 to disengage the movable block 46. The movable block 46 moves and resets under the elastic force of the spring 3 47, and the clamping wheel 45 rotates again to clamp the distribution network tower;

[0046] The operator connects the two sets of tightening hoops 1 by threading with bolts and other fasteners, keeps the two sets of tightening rings 31 in contact with the distribution network tower, tightens the bolts to connect the two sets of tightening hoops 1 but do not clamp them with the distribution network tower, then pushes the tightening hoop 1 upward until the positioning tooth block 1 311 on the tightening ring 31 is inserted into the gap between every two adjacent positioning tooth blocks 2 326 inside the tightening sleeve 32, and at the same time, the positioning plate 312 is inserted into the interior of the positioning ring groove 325 under the elastic force of the spring 1 313, and the positioning plate 312 can slide inside the positioning ring groove 325. At this time, the tightening ring 31 and the tightening sleeve 32 are connected to each other, and the tightening hoop 1 is positioned on the lower side of the fixing frame 2, and then the bevel gear 2 324 is rotated, and the bevel gear 2 324 and The bevel gears 1 323 mesh with each other and drive the gear 1 322 to rotate synchronously and mesh with the gear ring 321 to drive the tight sleeve 32 to rotate as a whole. When the tight sleeve 32 rotates, it can drive the tight ring 31 and the T-shaped cross arm assembly thereon to rotate for fine adjustment of the angle. When the T-shaped cross arm assembly is adjusted to the set position, the bolts and other fasteners between the two sets of tightening hoops 1 are rotated to clamp the two sets of tightening hoops 1 on the distribution network tower to complete the installation of the T-shaped cross arm assembly. During the later use of the T-shaped cross arm assembly, when a large wind force acts on the cross arm 11, the mutually meshed positioning tooth block 2 326 and the positioning tooth block 1 311 can improve the limiting effect of the cross arm 11, thereby ensuring the stability of the T-shaped cross arm assembly during use.

[0047] After the T-shaped cross arm assembly is installed, the operator rotates the gear three 454 and drives the movable pressure wheel 452 to rotate by meshing with the gear four 455. When the movable pressure wheel 452 rotates, it drives the protruding pressure plate 453 to rotate and contact the fitting block 457. When the protruding pressure plate 453 contacts the fitting block 457, an outward force is applied to it. The conical protrusion 456 moves to the outside of the inner sleeve 451. When the clamping wheel 45 clamps the distribution network tower, the conical protrusion 456 can increase the friction of the contact surface and improve the clamping effect.

[0048] During the use of the T-shaped cross arm assembly, the movable wheel 41 is in contact with the distribution network tower. If the T-shaped cross arm assembly is loose and moves downward during use, the movable wheel 41 in contact with the distribution network tower rotates. When the movable wheel 41 rotates, the drive gear 2 411 rotates and drives the connecting arm 1 42 to move. When the connecting arm 1 42 moves, it drives the connecting arm 2 43 to rotate toward one side of the distribution network tower and drives the clamping wheel 45 to further clamp the distribution network tower to prevent the T-shaped cross arm assembly from further sliding down.

[0049] The pull rope displacement sensor 21 can detect the downward movement distance of the T-shaped cross arm assembly on the distribution network tower. When it is detected that the downward movement distance of the T-shaped cross arm assembly exceeds the set safety range, it notifies manual maintenance.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.

[0051] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
