[0041] Example 1:

[0042] like Figures 1 to 4 As shown, the present invention provides a combined insulating pole holding device for safely replacing insulators and crossarms, comprising a cable support assembly 1, a crossarm support assembly 2 and a pole holding assembly 3, wherein the cable support assembly 1 is used to support the cable connected to the insulator to be replaced; the crossarm support assembly 2 is used to support the crossarm to be replaced; the pole holding assembly 3 is used to connect to the utility pole, and the cable support assembly 1 and the crossarm support assembly 2 are arranged at the top of the pole holding assembly 3. In this embodiment, the entire combined insulating pole holding device is first fixed to the utility pole using the pole holding assembly 3, and then the cable support assembly 1 is used to support the cable connected to the insulator to be replaced, thereby preventing the cable from sagging and shaking after being disconnected from the insulator, thereby effectively avoiding the risk of electric shock caused by contact between the cable and the staff; in addition, the crossarm support assembly 2 is used to support the crossarm. When the insulator is replaced, the setting of the crossarm support assembly 2 can effectively prevent the crossarm from loosening and falling due to changes in the connection structure, thereby effectively improving the safety of the insulator replacement work; at the same time, when the crossarm is replaced, the crossarm support assembly 2 can be used as an operating table, which can effectively support the crossarm, and can facilitate the replacement work while improving the safety of the replacement work.

[0043] The cable support assembly 1 includes an extension rod 11 and a support rod 12. The extension rod 11 is connected to the holding rod assembly 3 and extends along the cable. The bottom end of the support rod 12 is vertically connected to the extension rod 11, and the top end of the support rod 12 is used to support the cable. In this embodiment, the provision of the extension rod 11 allows the vertical position of the support rod 12 to be adjusted to the cable position on both sides of the insulator. The support rod 12 then supports the cable, thereby preventing the cable from drooping and shaking, thereby effectively preventing the cable from contacting the operator and causing danger.

[0044] The crossarm support assembly 2 includes a support portion 21 and a conveying portion 22. The support portion 21 is vertically arranged and connected to the holding pole assembly 3. The conveying portion 22 is disposed on top of the support portion 21 and is used to convey the crossarm.

The conveying portion 22 is preferably a roller disposed on top of the support portion 21, which utilizes the rolling motion of the roller to convey the crossarm, thereby facilitating crossarm replacement.

[0045] The pole holding assembly 3 includes an insulating rod 31, a pole holding member 32, and a connector 33. The pole holding member 32 is arranged on the insulating rod 31 and is used to fix and connect to the electric pole; the connector 33 is arranged at the top of the insulating rod 31 and is used to connect and support the cable support assembly 1 and the cross-arm support assembly 2. In this embodiment, the insulating rod 31 is preferably a hollow pipe, which not only reduces the weight of the device and is convenient to carry, but also allows the ground wire to pass through the hollow structure; the connector 33 is a plate structure with appropriate length and width, which can effectively meet the installation and fixation of the cable support assembly 1 and the cross-arm support assembly 2, and the force borne by the cable support assembly 1 and the cross-arm support assembly 2 is finally transmitted to the electric pole through the insulating rod 31 and the pole holding member 32, thereby achieving the supporting effect of the device on the cable and the cross-arm.

[0046] The top of the support rod 12 is provided with a cable groove 13 for securing the cable. The cable groove 13 supports the cables on both sides of the insulator. In this embodiment, the provision of the cable groove 13 at the top of the support rod 12 effectively improves the cable securing effect, prevents the cable from slipping, and thus improves construction safety. To further enhance safety, an insulating sleeve 14 for insulating the cable is provided on the side of the cable groove 13 away from the insulator, and the insulating sleeve 14 wraps around the surface of the cable.

[0047] Specifically in this embodiment, the cross arm support assembly 2 is composed of a plurality of support units, and each of the support units includes the support portion 21 and the conveying portion 22; the plurality of support units are evenly and equidistantly arranged on the connecting member 33 along the cross arm direction.

[0048] Example 2:

[0049] like Figure 5 As shown, this embodiment provides a lifting device based on Example 1. Specifically, the lifting device 4 is used to lift and lower insulators and crossarms. The lifting device 4 is a winch, and the winch is fixed to the holding pole assembly 3. The hoisting rope of the winch is used to connect the insulator or crossarm. Before disassembling the insulator or crossarm, the hoisting rope is first connected to the component to be disassembled to prevent it from accidentally falling from a high altitude, thereby improving construction safety. At the same time, the provision of the lifting device also facilitates the lifting of tools and parts, so operators do not need to carry heavy equipment when climbing the pole, thereby ensuring the safety of the construction work to a certain extent.

[0050] Example 3:

[0051] like Figure 6 As shown, this embodiment provides a grounding assembly structure based on Example 1. The grounding assembly 5 includes a cable contact 51, a grounding wire 52, and a grounding member 53. One end of the grounding wire 52 is connected to the cable contact 51, and the other end of the grounding wire 52 is connected to the grounding member 53. In this embodiment, the use of the grounding assembly can effectively ensure the safety of live operations. Specifically, the cable contact 51 is disposed in the cable slot 13, and when the cable is fixed in the cable slot 13, the cable contact 51 contacts the cable; the grounding wire 52 is passed through the insulating rod 31, and the grounding member 53 is movably connected to the bottom of the insulating rod 31.
