DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1-6 A T-shaped insulating crossarm hardware shown in the figure includes a first crossarm body 1 and a second crossarm body 2, a first hoop member 3 is provided between the first crossarm body 1 and the second crossarm body 2, a second hoop member 4 is provided below the first hoop member 3, the first hoop member 3 and the second hoop member 4 are connected by flange nuts, and second support blocks 41 are fixedly installed on both sides of the second hoop member 4, the first crossarm body 1 and the second crossarm body 2 are located in symmetrical positions, the first crossarm body 1 and the second crossarm body 2 both include a connecting block 11, and the connecting block 11 is fixedly installed on the first hoop member 3, an anti-slip chain 31 is provided between the first hoop member 3 and the second hoop member 4, and the two ends of the anti-slip chain 31 are respectively fixedly installed on the connecting block 11 and the second support block 41, when in use, the first crossarm body The body 1 and the second crossarm body 2 directly bear the weight of the insulator and the high-voltage line, and the device is mostly installed at a higher position. It will shake when exposed to wind for a long time, which may easily cause the nuts at the connection to fall off or be damaged. Damage to the nuts may cause the first crossarm body 1 and the first clamping member 3 to fall off, thereby causing a safety hazard. Therefore, by providing the second clamping member 4 and the anti-detachment chain 31, the first clamping member 3 and the second clamping member 4 are both engaged with the pole during installation. Because the second clamping member 4 is subjected to less force in a normal state, it will not be damaged. When the first clamping member 3 is damaged and falls off, the anti-detachment chain 31 will tie the first crossarm body 1 and the second crossarm body 2 to prevent them from falling, thereby playing a role of early protection and reducing the occurrence of safety hazards.

[0025] A first support block 12 is fixedly installed on one side of the connecting block 11, a support plate 14 is fixedly installed on the side of the first support block 12 away from the connecting block 11, a core body 13 is fixedly installed in the middle of the first support block 12, a rotating rod 17 is rotatably provided in the middle of the support plate 14, a slide groove 15 is opened in the middle of the support plate 14, a pull rod 16 is rotatably provided inside the slide groove 15, and the pull rod 16 is fixedly installed in the middle of the rotating rod 17, sliding mounting seats 6 are slidably sleeved on the outside of both sides of the core body 13, and a plurality of evenly distributed silicone rubber umbrella sleeves 19 are slidably sleeved on the core body 13.

[0026] A sliding block 62 is fixedly installed on one side of the sliding mounting seat 6 close to the rotating rod 17, and a matching hole 63 is provided on the sliding block 62, and a rubber block 18 is fixedly installed on the outside of the rotating rod 17. The rubber block 18 and the rotating rod 17 are both movably clamped in the matching hole 63, and matching holes 63 are also provided on multiple silicone rubber umbrella covers 19.

[0027] When the umbrella skirt on the traditional insulating cross bar is damaged, it needs to be replaced as a whole. Replacement will not only increase the maintenance time and cause inconvenience in electricity use, but also increase the operation and maintenance cost of the device. When in use, first install the device as a whole at the target position, and then push the pull rod 16 upward. At this time, the rotating rod 17 and the rubber block 18 are just engaged with the matching hole 63, and will not cause squeezing on the inner wall of the matching hole 63. At this time, the silicone rubber umbrella cover 19 and the sliding mounting seat 6 can slide along the core body 13, pulling the pull rod 16 downward, and the rotating rod 17 and the rubber block 18 are driven to rotate, so that the rubber block 18 will squeeze the inner wall of the matching hole 63. At this time, the silicone rubber umbrella cover 19 and the sliding mounting seat 6 cannot move. Therefore, by setting the rotating rod 17, when the silicone rubber umbrella cover 19 at a certain place is damaged, the sliding mounting seat 6 can be removed from the core body 13, and then the damaged silicone rubber umbrella cover 19 can be removed from the core body 13 and replaced with a new silicone rubber umbrella cover 19. There is no need to replace the entire device, and there is no need to disassemble the device. Only the components at the corresponding position need to be replaced, which greatly reduces the maintenance cost of the device and reduces the steps of repeated disassembly, thereby reducing the time required for maintenance and improving the practicality of the device.

[0028] A mounting frame 61 is fixedly installed on the top of the sliding mounting seat 6. The mounting frame 61 is used to connect an external insulator. The insulator can be a common insulator on the market. A second clamp 64 is fixedly installed on the bottom end of the sliding mounting seat 6. First clamps 42 are fixedly installed on both sides of the second support block 41. A threaded telescopic rod 5 is detachably installed between the second clamp 64 and the first clamp 42. One end of the threaded telescopic rod 5 is rotatably installed on the second clamp 64, and the other end of the threaded telescopic rod 5 is rotatably installed on the first clamp 42. The threaded telescopic rod 5 is used to share the weight of the first crossarm body 1 and the second crossarm body 2, and form a triangular stable structure, so that the device is more stable when in use and has a longer service life.
