[0027] Please refer to Figure 1 and Figure 2 , a conductor crossing device, comprising a ground fixed base 1, an adjustable telescopic rod 2 and an insulating support platform 3;

[0028] The bottom end of the adjustable telescopic rod 2 is arranged on the ground fixed base 1, and the insulating support platform 3 is arranged on the top of the adjustable telescopic rod 2. At least two guide support wheels 4 are arranged on the insulating support platform 3 along the first horizontal straight line direction, and the guide support wheels 4 are used to support the wires.

[0029] From the above description, it can be seen that the beneficial effects of the utility model are: it is composed of a ground fixed base 1, an adjustable telescopic rod 2 and an insulating support platform 3. When in use, the insulating support platform 3 is made to reach the crossing position by adjusting the adjustable telescopic rod 2. The bottom of the device is fixed by the ground fixed base 1, and then the crossing wire is placed on the guide support wheel 4. With the help of the guide support wheel 4, the wire is kept in a horizontal extension state. During the crossing process, there is no need to disconnect the current of the wire below the crossing position and to specially build a crossing frame. The wire crossing can be completed safely and conveniently, thereby improving work efficiency.

[0030] Furthermore, the ground fixed base 1 comprises a mounting base plate 11;

[0031] The bottom end of the adjustable telescopic rod 2 is arranged at the center of the mounting base plate 11 . The mounting base plate 11 is provided with at least two positioning holes 13 distributed around the center. The positioning holes 13 are provided with iron rods.

[0032] From the above description, it can be seen that the support floor is used as the fixing foundation to reduce the space restriction requirements for the site. When fixing, an iron rod is used to pass through the positioning holes 13 distributed around the center and inserted into the ground. The fixing operation is simple and stable.

[0033] Furthermore, the ground fixed base 1 also includes at least two fixing cables 12;

[0034] One end of the fixing cable 12 is connected to the adjustable telescopic rod 2 , and the other end of the fixing cable 12 is provided with a ground nail.

[0035] From the above description, it can be seen that on the basis of the iron rod inserted into the ground, a fixing cable 12 is added to improve the overall wind resistance and impact resistance of the device, meet the needs of outdoor use, and improve the stability of the device.

[0036] Furthermore, the adjustable telescopic rod 2 includes a support rod 21 and a lifting mechanism 22;

[0037] The lifting mechanism 22 is disposed on the ground fixed base 1 , the bottom end of the support rod 21 is disposed on the movable end of the lifting mechanism 22 , and the insulating support platform 3 is disposed on the top end of the support rod 21 .

[0038] From the above description, it can be seen that the adjustable telescopic rod 2 is divided into two parts, with the support rod 21 and the lifting mechanism 22 in the initial state as the basic length of the device support part. In response to actual installation requirements, the lifting mechanism 22 can be flexibly adjusted to adapt to the crossing of wires at different heights; at the same time, the lifting mechanism 22 with a larger counterweight is connected to the ground fixed base 1, which can also lower the center of gravity of the device.

[0039] Furthermore, the lifting mechanism 22 and the support rod 21 as well as the support rod 21 and the insulating support platform 3 are detachably connected.

[0040] Furthermore, the lifting mechanism 22 and the support rod 21 as well as the support rod 21 and the insulating support platform 3 are all connected by bolts.

[0041] From the above description, it can be seen that the various components of the device can be detachably connected, and specifically can be connected using firmly connected bolts, which is convenient for storage management and carrying and installation.

[0042] Furthermore, the insulating support platform 3 is provided with protective baffles 5 on both sides in a second horizontal straight line direction perpendicular to the first horizontal straight line direction.

[0043] From the above description, it can be known that by providing the protective baffle 5, the wire that has deviated from the guide support wheel 4 can be blocked to prevent it from deviating to a position outside the entire insulating support platform 3, thereby improving the reliability of the device.

[0044] Furthermore, a wire limiting groove is provided on the wheel surface of the guide support wheel 4.

[0045] It can be seen from the above description that by setting the conductor limiting groove, the crossing conductor can be horizontally limited to improve the safety of conductor operation.

[0046] Furthermore, the position of the guide support wheel 4 on the insulating support platform 3 is adjustable.

[0047] It can be seen from the above description that the position of the guide support wheel 4 on the insulating support platform 3 is adjustable, so that the guide support wheel 4 can be adjusted according to actual wiring requirements to improve the flexibility of the device.

[0048] Please refer to Figure 1 and Figure 2 , Embodiment 1 of the present utility model is:

[0049] A conductor crossing device comprises a ground fixed base 1, an adjustable telescopic rod 2 and an insulating support platform 3;

[0050] The bottom end of the adjustable telescopic rod 2 is arranged on a ground fixed base 1, and the insulating support platform 3 is arranged on the top of the adjustable telescopic rod 2. At least two guide support wheels 4 are arranged on the insulating support platform 3 along the first horizontal straight line direction, and the guide support wheels 4 are used to support the wires.

[0051] Among them, the adjustable telescopic rod 2 includes a support rod 21 and a lifting mechanism 22; the lifting mechanism 22 is arranged on a ground fixed base 1, the bottom end of the support rod 21 is arranged on the movable end of the lifting mechanism 22, and the insulating support platform 3 is arranged on the top end of the support rod 21; the lifting mechanism 22 and the support rod 21 as well as the support rod 21 and the insulating support platform 3 are all detachably connected.

[0052] The use process of the wire crossing device of this embodiment includes:

[0053] First, according to the actual spanning position, the lifting mechanism 22 is fixed on the ground through the ground fixed base 1;

[0054] Secondly, according to the height requirement of the crossing position, the height of the movable end of the lifting mechanism 22 is adjusted; wherein, the lifting mechanism 22 adopts a sleeve-type structure, which is composed of an outer cylinder providing a movable groove and an inner cylinder telescopically arranged in the sliding groove; the two can be relatively fixed by a limit pin, or a push rod motor can be arranged in the movable groove to realize automatic lifting.

[0055] Then, the insulating support platform 3 is adjusted to the crossing position, and the support rod 21 at the bottom of the insulating support platform 3 is connected to the movable end of the lifting mechanism 22;

[0056] Finally, the wire is laid out from one end of the insulating support platform 3 to the other end along the first horizontal straight line direction with the help of the guide support wheel 4 to complete the crossing. Among them, the position of the guide support wheel 4 on the insulating support platform 3 is adjustable. After the installation position of the ground fixed base 1 is determined in combination with the crossing position, the actual crossing direction of the wire relative to the insulating support platform 3 will also change. At this time, it is easy for the position of the guide support wheel 4 to be inconsistent with the guide extension direction. Therefore, the position of the guide support wheel 4 can be adjusted to flexibly respond to actual needs.

[0057] In this embodiment, the ground fixing base 1 includes a mounting base plate 11 and at least two fixing cables 12; the bottom end of the adjustable telescopic rod 2 is arranged at the center of the mounting base plate 11, and the mounting base plate 11 is provided with at least two positioning holes 13 distributed around the center, and the positioning holes 13 are provided with iron rods. One end of the fixing cable 12 is connected to the adjustable telescopic rod 2, and the other end of the fixing cable 12 is provided with a ground nail. When the device is fixed to the ground through the ground fixing base, the iron rod is specifically used to pass through the positioning hole 13 and the ground one by one for fixing, and then one end of the fixing cable 12 is fixed to the lifting mechanism 22, and the other end of the fixing cable 12 is inserted into the ground through the ground nail while keeping the fixing cable 12 straight.

[0058] In this embodiment, the lifting mechanism 22 and the support rod 21 as well as the support rod 21 and the insulating support platform 3 are connected by bolts; in other equivalent embodiments, the connection can also be made by adding a fixing ring or other means.

[0059] In addition, the insulating support platform 3 is provided with protective baffles 5 on both sides in the second horizontal straight line direction perpendicular to the first horizontal straight line direction. A wire limiting groove is provided on the wheel surface of the guide support wheel 4. The wire limiting groove and the protective baffle 5 form a double limit, which can effectively prevent the wire from detaching from the insulating support platform 3 and contacting the wire below.

When in use, the insulating support platform is made to reach the crossing position by adjusting the adjustable telescopic rod, and the bottom of the device is fixed by the ground fixed base.

With the help of the guide support wheel, the conductor is kept in a horizontal extension state, and a double limit is formed by a conductor limit groove and a protective baffle. During the crossing process, there is no need to disconnect the current of the conductor below the crossing position and to specially build a crossing frame. The conductor crossing can be completed safely and conveniently, thereby improving work efficiency.
